Flat washer manufacturer, tell you the characteristics of the material in thin flat washer stamping [hardware]

Flat washer manufacturers, in the production of flat washers, will encounter the production of thick materials, but also the production of thin materials. What are the precautions when producing thin flat washers? Next, Xiaoshuo sorts out a few points, and understands with you: 1, the stamping gap of the mold The reasonable gap of the stamping die is based on the overlap of the upper and lower cracks when the sheet is broken. The smaller the thickness of the punched sheet, the smaller the projection length of the crack on the surface, and the smaller the gap of the punching die used. 2. Thin material stamping parts have larger springback but better cross-section quality. Thin material has greater deformation during stamping. When stamping is completed, the workpiece must return to its original shape and produce greater springback. However, due to the small stamping gap and sheet thickness, the resulting stamping section is perpendicular to the surface, the section is bright and wide, and the composition of the section is not easy to distinguish, and the quality of the section is better. 3. The characteristics of the thin plate stamping die. The gap of the thin plate stamping die is small. When the die adopts a common stamping die structure, the mold base used is required to have high accuracy. The guide pin and guide sleeve of the mold base should be matched to H6/h5. , The guide sleeve should not be detached. And the use of floating mold handle and ball guide sleeve structure. In order to make the gap between the convex and concave molds can be adjusted during the working process, the concave mold can adopt the mosaic structure or not quenching. The structure of the non-quenched concave die is to stamp complex parts and improve the accuracy of stamping parts. At present, polyurethane rubber dies are commonly used to stamp soft and thin materials below 1 mm. Thin parts can also be stamped with large gaps. The concave mold is made with rounded corners, and the convex mold is made with sharp cutting edges. After the pressing plate is pressed against the sheet under the strong force of the spring, the material is pulled down by the sharp edge of the punch, and the size of the workpiece is generally the same as that of the punch. 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 mold processing capacity, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, 16 quality inspection layers The layer is strictly controlled. It can quickly solve the time-critical problem for you, solve the problem of flat washer stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
