Shanghai Metal Stamping Co., Ltd., mold maintenance method + 16 strict quality inspections

The technicians of Shanghai Metal Stamping Parts Co., Ltd. have introduced the maintenance methods of some stamping dies. The following Xiaoshuo has collected some relevant knowledge and let you take a look: (1) Mold looseness: the amount of movement of the punch or die exceeds Unilateral clearance. Adjust the combination gap. (2) Die tilt: The straightness of the punch or die is not correct, or there is foreign matter between the templates, which makes the templates unable to be flat. Reorganize or grind correction. (3) Template deformation: The template is not sufficiently rigid or thick, or deformed by external force. Replace with a new template or correct the method of disassembly. (4) Deformation of the mold base: the thickness of the mold base is insufficient or the force is uneven, and the straightness of the guide post and the guide sleeve varies. Grinding and correcting or refilling plastic steel or replacing the mold base or equalizing the force. (5) Die interference: Whether the die size and position are correct, whether the upper and lower die positioning is deviated, whether it will loosen after assembly, the accuracy of the punch is different, and the die frame is not correct. (6) Punching shear deflection: The punch strength is not enough, the big and small punches are too close, the lateral force is not balanced, and the punch is semi-oblique. Strengthen the guiding and protection function of the sloping board or increase the punch, shorten the small punch and increase the heel length to support and guide early, pay attention to the length of the feed. Hardware, 15 years of ingenuity focused on metal stamping parts processing, 20000+ sets of stamping die customized production experience, monthly 100+ sets of mold processing capacity, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and stamping accuracy up to 0.01mm , The raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
