Flat washer manufacturers, know the knowledge about flat washer processing[]

Flat washer manufacturers produce flat washers in thin and thick. I have introduced the stamping matters of thin materials before, and today Xiaoshuo will take everyone to understand the matters needing attention when stamping thick flat washers: 1. Thick plate stamping, the gap used by the mold is large. 2. The thicker the material, the greater the punching deformation force, and the greater the working stroke of the punch. When selecting a punch, care should be taken to make the required punching pressure less than the actual pressure that the punch can allow. Because the work hardening phenomenon is more obvious when the thick plate is stamped, the shear strength of the plate is slightly larger than that of the thin plate. When t/d>0.3, the shear strength of the thick plate is about 30% higher than that of the thin plate (t is the plate thickness, d is the diameter of the round stamping part or the side length of the square stamping part). The unloading force of thick material stamping is relatively large, and the rigid unloading device or air cushion is generally used to complete the unloading. 3. Using ordinary methods to stamp thick plates, the dimensional accuracy and section finish of flat washers are relatively low (generally not higher than IT grade and V3~V4). If you want to improve the quality, you can increase the refurbishment process or switch to precision stamping. Hardware, 15 years of ingenuity and focus on flat washer manufacturers, 5000 square meters production workshop, hundreds of precision processing production equipment, monthly 100+ sets of customized mold processing capacity, daily production capacity of 3 million strokes, stamping accuracy up to 0.01mm, 16 quality inspections Strict checks at all levels. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
