3. Check whether the cylinder action is flexible and consistent; if a cylinder action lags, you need to replace the new cylinder.

1.4 air supply

Every day before starting the machine, you should check whether the water in the pneumatic triplex and filter is drained or not; if there is residual water in the pneumatic triplex and filter, it should be drained before starting the machine, the pneumatic triplex equipped with this machine is the automatic drainage type, which can be drained automatically after disconnecting and relieving the pressure, if the automatic draining function is faulty, please replace with a new pneumatic triplex.

1.5 Head section maintenance

The head section is a key part of the equipment and is serviced at least once a month.

1.5.1. Regular cleaning.

To ensure the air tightness of the head, the head should be thoroughly scrubbed once a month, especially the fixture part, which should be carefully cleaned. The cleaning process is as follows:

(1) Click the ‘Clamping Effective ’ button in the function setting interface to close the clamping enable, click the ‘Rotary Control’ button in the main interface to make the machine run at low speed, press the inspection button, and all the fixtures will be in the open state after one week of machine operation;

(2) Press the test button, click the main interface ‘rotary control’ button, shut down the power supply, and clean the machine.

1.5.2. Regularly check the air tightness of the air circuit.

(1) Click the ‘Clamping Effective ’ and ‘Opening Effective ’buttons in the function setting interface to switch off the clamping function, click the ‘ Slewing
The control button in the main interface makes the machine run at low speed, and the ‘Inspection ’button is pressed. Press the detection button; all the fixtures will be in an open state after one week of operation;

(2) Put qualified gloves on all fixtures and apply soapy water on the wrist joints of the gloves (for easy observation of air leakage);

(3) Then click on the main interface ‘Clamping Effective ’ to open the clamping enable, click on the main interface ‘rotary control ’ button to make the equipment run at low speed, press the test button, and all the fixtures are clamped after one week of operation, and at the same time, the gloves are filled with gas;
(4) Press the test button, click the ‘rotary control ’button on the main interface,
observe the air bubbles after stopping the machine and check whether the air tightness is good.

1.6 Maintenance of electrical parts

(1) To improve the service life of the equipment, it is generally required to avoid direct sunlight and other heat radiation and to avoid places that are too humid, dusty, or have corrosive gases. Corrosive gases are prone to corrosion and deterioration of electronic components, resulting in poor contact or short-circuit components, affecting the normal operation of the equipment;

(2) The control cabinet door should be opened as little as possible. There are oil mist, dust, and other magazines in the air of the production workshop; once they fall on the circuit board or electronic devices in the control system, it is easy to cause the insulating resistance between the components to drop, and even lead to the damage of the components and circuit boards;

(3) Electrical parts such as electromagnetic switches, travel switches, etc., are all electrical-wearing parts. When the equipment fails, cut off the power supply the first time, let the professional electricians overhaul and investigate, and forbid the non-professionals to overhaul and operate blindly;

(4) operation buttons should be light, prohibit tapping the operating panel, and daily maintenance components should be careful; the surface of the dust clean up; do not scratch the components with a sharp object; do not use a damp rag to wipe the circuit board and exposed components. And often keep the electrical cabinet dry and ventilated;

(5) Clean the oil and dust on the main motor every March. If the motor is abnormally hot, it must be repaired and dealt with in time, and if it cannot be eliminated quickly, the machine operation should be suspended.

2. Other

(1) Keeping the machine clean, both externally and internally, is essential for ensuring its long life and high production efficiency.

Therefore, frequent and thorough removal of foreign objects, dirt, and deposits on the surface of the machine and all internal parts is required, and the machine should be
carefully maintained on time;

(2) When cleaning the machine, do not use sharp tools or corrosive cleaning agents;

(3) When the machine is working, it is not allowed to place any tools or other items that affect the work of the machine head on the machine;

(4) When scrubbing, the machine must be pulled down, and the electric switch stop working;

(5) The use of the cloth, preferably a whole piece of cloth, should not use bits and pieces of fabric;

(6) in the scrubbing, at the same time, should be on the machine oil eyes, oil, and parts of the inspection, timely detection of problems promptly;

(7) After scrubbing the machine, carry out a comprehensive inspection to see
whether there is a wipe and other items fall into the machine inside so as not to cause machine accidents;
(8) In daily production, the machine around and work environment hygiene also need to pay attention to, especially before work should be cleaned.

(9) If there is any abnormal noise in the process of operation, we should stop the work immediately, find out the cause of the noise, and exclude it before continuing the

operation, and strictly prohibit the equipment from ‘working with disease’, which may cause damage to the equipment.

3. Head power belt repair and replacement

The head power belt should be inspected every three months and repaired or replaced if there are obvious signs of damage or if the diamond nut tends to fall off.

3.1 Maintenance of the head power belt

The active belt of the head is a disposable polyurethane synchronous belt with three sets of mounting holes punched in the belt at the factory. Under the premise that the belt does not break if the connecting block of the head and the belt is dislodged from the belt due to external force, head jamming, mechanical fatigue, etc., even if the holes in the belt are not damaged after the dislodging, a set of mounting holes for the connecting block of the head and the belt should be replaced to continue the production. It is not permitted to return the head to its original position to continue production to avoid the connecting block of the head and the belt dislodging again from the belt, which would cause more damage to the equipment. Damage to the equipment.

3.2 Head power belt replacement

 

The procedure for replacing the header belt is as follows:

The preparation before replacing the header belt is the same as that for replacing the header belt connecting block mounting holes. Firstly, tap the walker to move the header belt connecting block of the header closest to the main wheel, and mark the teeth corresponding to the main wheel and the header belt connecting block, and note down the number of the header located in this position at this time, as shown in Fig. 3.2.1.
Firstly, remove the upper circular guide at the main pulley to make it easier to remove the belt. The rest of the guides must not be removed to ensure the accuracy of the inspection.

Then, remove the belt connecting blocks from all the machine heads, remove all the diamond nuts from the belt, and install them in the corresponding mounting holes on the new belt. Loosen the belt pulley set screw, turn the belt tensioning screw, loosen the belt until it can be removed from the four timing pulleys, remove the belt from the removed arc guide rail, and set the belt into the gap between the heads on the outside of the upper guide rail, then manually push the head to make the 36 heads rotate along the guide rail to remove the old belt, and in the same way can be put the new belt into the synchronous belt pulleys. The new belt can be put on the timing pulley similarly. When the new belt is put back on the timing pulley, first put the belt on the main pulley, and then make sure that the teeth where the diamond nut is located are put on the teeth corresponding to the marks of the timing pulley so that there are no wrong teeth.

Then put the belt into the remaining three driven pulleys and then adjust the tensioning screw to tighten the belt and the driven pulleys back to the original position. Finally, reinstall the head belt, connecting the block to the fixing holes in the belt. When reinstalling the head, first reinstall it at the marking of the active pulley, making sure that the head number here is the same as the one before removal. Otherwise, the head number must be initialized after the skin replacement. Finally, check all the screws and make sure they are all tight. This completes the replacement of the header belt connecting block mounting holes.

After replacing the head belt connecting block mounting holes, check that the head position is correct before continuing production.

4 . Replacement of synchronous belts in reciprocating mechanisms

The synchronous belt of the reciprocating mechanism is subjected to large and complex forces and should be inspected once a month. If the belt is loosened, it should be tensioned in time; if the synchronous belt shows apparent signs of breakage or there are signs that the belt teeth have fallen off, it should be replaced in time.

As shown in Fig. 4.1, loosen screws 1, 2, 3, and 4 indicated by arrows in the figure, and then loosen screw five slowly until the synchronous belt can be removed. Install the new synchronous belt, then screw 1, 2, 3, and 4 until the cap of the screw is just in contact with the spring pad; tighten screw 5 to tension the synchronous belt to the appropriate tension, and then tighten screws 1, 2, 3, 4 can be.

The two synchronous belt pulleys must be kept stationary during the whole operation; if there is any rotation of the pulleys during the operation, after the belt is mounted, check whether the relative positions of the male end of the butt joint and the female end of the machine head meet the requirements (deviation within ± 3mm), and adjust the phasing of the reciprocating mechanism if it does not meet the criteria. Ensure that the relative positions of the male butt joint and the female head meet the requirements before restarting the equipment.

5. Replacement of guide rod cylinders and buttressing males

5.1 Replacement of guide rod cylinder

The male butt joint should be inspected once a month; if the male head is seriously worn or there is air leakage, it should be replaced in time. An alarm will be indicated if the guide cylinder needs to be replaced or malfunctions. Even if the guide cylinder still usually works after the alarm indication, the guide cylinder must be replaced to prevent the guide cylinder from suddenly malfunctioning and damaging the equipment.
As shown in Figure 5.1.1, first remove the air tube from the male head, then use a 4mm hexagonal spanner to remove one of the screws in the figure, and then the cylinder male head assembly can be taken down as a whole. Remove all parts of the old cylinder and replace them with the new cylinder, then reinstall the cylinder head assembly to its original position. When reinstalling, pay attention to the bottom of the cylinder and the step surface indicated in Figure 2, and at the same time, make the side of the cylinder coincide with the surface indicated in Figure 3, so as to make sure that the cylinder is the same as the one before disassembling when reinstalled to its original position.

5.2 Replacement of the male butt joint

As shown in Fig. 5.2.1, there is no need to disassemble the cylinder when replacing the butt joint male head; just remove the screws indicated by the arrows in the figure to remove the male head assembly, then remove the quick coupling on the male head, and then remove the retaining ring to take out the male head, and then put the parts back in order after replacing with a new male head.

6. Replacement of fixtures

When replacing the fixture, the whole set must be replaced, including the guiding vertebrae, the clamping core, and the clamping sleeve.

Note: The fixture is made of nylon, the tightening torque should not be too large, and when the threads are not tightened well, do not use brute force to tighten them, so as not to damage the threads!

Step 1: Remove the clamping core
As shown in Fig. 6.6.1, remove the clamping core by removing the two M8 screws and the two combination washers 1, clamping core 2, and O-ring 3, indicated by the arrows in the figure; (There is a seal on each screw when removing it, so be careful to keep it in place! Screw 1 must be fitted with a combination sealing washer, flat washers or spring washers are not permitted!)

Step 2: Remove the clamping sleeve
Remove the clamping plate four and the clamping sleeve five by removing the four M8 hexagon socket head cap screws 6, indicated by the arrows in the illustration, as shown in Figure 6.6.2;

Step 3: Install the new clamping core and clamping sleeve back in the original way.
Load back when the first clamping sleeve, and then load the clamping core (pay attention to the dense three seals. Do not miss the installation); the clamping core and the clamping sleeve back to install the first fastening screws can not be tightened to death, tighten to the screw and the parts just contact with the parts. There is a slight gap that can be adjusted for the best, all the heads of the clamping core and the clamping sleeve are assembled and dutifully, the first time after the tightening, the set on the O-ring seals, open the device, set to ‘open invalid ’ ‘clamping effective,’ run a circle, so that all the heads of the clamp are in the clamping of the clamp. ‘open invalid ’ ‘clamping effective,’ run a circle so that all the heads of the fixture are in the clamping state, and then again on the clamping sleeve and the clamping core of the screws for the second time fastening. To ensure the concentricity of the clamping sleeve and the clamping core, the clamping core of the screw fastening can not be tightened once in place; the two screws should be repeated several times alternately fastened, each time to increase the torque a little bit until completely tightened so far.

Step 4: Check the sealing performance of the fixture
The clamping core and clamping sleeve are fastened after the completion of the test with soapy water to check the airtightness of the fixture. If there is an individual fixture leakage phenomenon, check whether the sealing ring is leakage; if leakage, install the sealing ring according to the requirements of the fifth step again after tightening and then check the fixture’s airtightness; if the sealing ring is not leakage, all the screws will be loosened according to the fifth step of the way to reassemble, adjust the relative position of the clamping core and the clamping sleeve, so that the two are concentric and then again after tightening, and then again airtightness test until all the fixtures are not leakage. Then, recheck the airtightness until all fixtures have no air leakage.
