Progressive die maintenance, must be careful, patient, step by step, do not blindly engaged in.Due to the breakdown of the mold, the need to attach the material belt, so that the problem of inquiry.Open the mold, check the status of the mold, confirm the cause of the fault, find out the problem, then clean the mold, clean off the debris, etc., before the mold is removed.When dismantling the mold, the force should be uniform.Die maintenance essentials progressive die maintenance, must be careful, patient, step by step, do not blindly engaged in.Due to the breakdown of the mold, the need to attach the material belt, so that the problem of inquiry.

Open the mold, check the status of the mold, confirm the cause of the fault, find out the problem, then clean the mold, clean off the debris, etc., before the mold is removed.When dismantling the mold, the force should be uniform.In view of the mold structure of the unloading spring between the upper die (fixed) plate and the unloading plate, the disassembly of the unloading plate by the firing gun barrel manufacturer should be balanced and ejected.The tilt of the discharge plate may lead to the rupture of the punch in the die.

(1) the maintenance of convex die, die disassembly, should pay attention to the original condition of the mold

When the total length of the punch becomes shorter after maintenance and the gasket needs to be added to reach the required length, check whether the effective length of the punch is sufficient.When using a new punch or die insert, pay attention to the treatment of clean corners.Due to the wear of the grinding wheel in grinding, there will be a small R in the concave and clear Angle. Relative to the outer convex point, it is also necessary to manually fix R to make the matching gap reasonable.More attention should be paid to the formed small protrusions.Replace the broken punch, check the cause, at the same time, check the die whether it has caused the edge breakage, whether it is necessary to grind the edge.Die assembly, should be incorporated into, and then use a flat iron on mold core lightly with copper bar in place, must not oblique and rely on strong type (if necessary, can be in the bottom of the mold core Angle pouring R in order to easily import), such as uneven when assembly, set up under the die gasket should level off, generally no more than two pieces (and as far as possible use GangDian), otherwise easy to cause the die dimension unstable fracture or forming (especially forming).After the punch and core are assembled, necessary inspection should be made on the care belt to check whether the parts are installed wrong or upside down, check whether the concave core is inverted, and assemble the loading and unloading board or closing the mold after confirming the correctness.Pay attention to do unloading plate screw lock confirmation, ignition barrel direct to get enough locking force.When locking should be from inside to outside, cross lock with balanced force, do not lock one screw at a time and lock the other screw again, otherwise it will cause punch fracture or reduce the precision of the mold.

(2) the maintenance of the unloading plate unloading plate disassembly, two screwdriver balance can be used to pry up

In case of disassembly difficulties, check whether the mold is clean, whether the locking screws have been completely removed, and whether the mold is damaged due to stuck materials.Find out the reason, make corresponding processing again, must not handle blindly.When assembling the unloading board, first clean the punch and the unloading board, add lubricating oil to the guide column and the leading part of the punch, put it into a stable position, use rubber mallet or copper bar to strike it into a proper position, then press it into place with both hands and repeat several times.If it is too tight, please check the reason: whether the guide post and guide sleeve are normal, whether all parts are damaged, whether the new parts have been properly treated (such as punch is chamfered, whether it can pass the unloading plate, etc.), find out the reason, and then make appropriate disposal.If the material contact surface between the unloading plate and the die is pressed for a long time, the material thickness between the unloading plate and the die is generally reduced by 0.03-0.05mm. When the indentation is serious, the pressing accuracy of the material will be affected, resulting in the abnormal size and instability of the product. Therefore, the material panel insert and the unloading plate should be repaired or re-ground.The accuracy of contour sleeve should be checked. When it is unequal in height, the unloading plate will tilt, and its function of precise guidance and smooth spring pressure will be destroyed. Therefore, it must be maintained.

(3) guide parts of the inspection guide column, guide sleeve clearance

Guide parts wear and accuracy of the destruction, so that the accuracy of the mold, mold parts will appear problems, it must be appropriate maintenance and regular replacement.Check the accuracy of the guide parts. If the guide pin is worn, it has lost the guide accuracy and function of the guide belt, it must be replaced.The air cover of precision lighter shall check the status of spring (unloading spring and feeding spring, etc.), depending on whether the spring is broken, or it has lost its original strength due to fatigue even though it has not been broken for a long time. Regular maintenance and replacement must be carried out, otherwise it will cause damage to the mold or make the production not smooth.
