Punching molding production quantities of parts is one of the practical process. Stamping die failure is the most prone to problems, often resulting in shutdown, the impact of the production cycle. Thus, the mold must be found as soon as possible cause of the malfunction, reasonable maintenance.
1, mold damage
Mold damage refers to mold cracking, breaking, etc. open up, deal with the problem of mold damage, it is necessary to find the reasons from the mold design, manufacturing processes and the use of molds. If foreign bodies into the mold, overlapping parts, waste obstruction without timely treatment, inheritance processing, it is easy to mold damage blanking plate, punch down the template and guide posts. Design of high spring force is too small or do not set high, can make spring break, blanking plate tilted cause overlapping washed up, damaged parts. If mold damage quenching temperature is too high, quenching methods, and time is not fair, as well as between the tempering temperature and frequency, elbow inappropriate choice, will lead into the mold after stamping production. Punch or improper screw fixing strength is not enough. Will lead the punch dropped or broken. Working height adjustment is too low, insufficient lubrication of the guide post. Typically, the heat treatment process mold material to its influence. Blanking aperture size or depth of the design is not enough, easy to make slots obstruction, causing damage blanking plate. When the use of molds, parts, directions and other installation errors or bad bolt.
2, the card mold
Cards are the main cause of mold: mold guide is not correct, tilt. Otherwise, the fault will be expanded, leading to mold damage. Deformation caused by mold, such as mold base, hardness template design thickness is too small, easily deformed by external impact; not allowed to install mold position, the upper and lower mold positioning error tolerance. At this time should progress punch strength, and enhance the protection of the discharge guide plate. Accuracy or bad press, so that the mold to produce interference; punch strength is not enough, the size of the ram position too close to the mold lateral force imbalance. Stamping process, once the mold clamping is not flexible, even stuck, it must immediately produce rest, find the reason for the card mode, troubleshooting.
