3. Inspection of guide parts

How about the fitting gap of guide post and guide sleeve, whether there are burns or wear marks, and whether the oil feeding state of the mold guide is normal, should be checked.Guide wear and accuracy of the destruction, so that the accuracy of the mold reduced, progressive die parts will appear problems, it must be appropriate maintenance and regular replacement.

(1) check the accuracy of the guide parts, if the guide pin wear, has lost the due material belt guide accuracy and function, must be replaced.

(2) check the status of the spring (unloading spring and spring, etc.), according to whether it is broken, or long time use although not broken, but has lost the original strength of fatigue, must be regular maintenance, replacement, otherwise it will cause damage to progressive die or production is not smooth.

4. Care of unloading board

The disassembly of discharge board, the outer cover of lighter flamethrower can use two screwdrivers to balance to pry up, and then use both hands to balance to take it out.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.

Contact area between the stripper plate and die materials, long time stamping produce indentation (stripper plate between the die and the material thickness reduction in capacity of aggregate is commonly 0.03 0.05 mm, when indentation is serious, affect materials repression of precision, destabilize product size abnormalities, such as, lighter wind cap custom need to plate edge and stripper plate for repair or regrinding.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.

In a word, for the progressive die in the stamping production of the fault, need to do specific analysis, die maintenance is often ignored, such as the mold guide accuracy, guide accuracy and the use of the spring inside the mold, will affect the other parts of the mold, must make regular inspection and maintenance.
