Shandong automotive hardware stamping parts, several experience in designing stamping dies + 20,000 sets of mold development experience

The hardware responsible for the Shandong automotive hardware stamping parts manufacturer has talked about several necessary experiences about stamping die design. If you understand these, you are the entry-level stamping die design. The following Xiaoshuo will take everyone to learn: 1. Before designing the material belt , We must master the dimensional tolerance regulations of the parts, material characteristics, high-speed punching capacity, high-speed punching cabinet countertops, SPM (per minute punching), feeding orientation, feeding aspect ratio, mold thickness regulations, material utilization rate, Mold life. 2. When designing the material belt, additional CAE analysis should be carried out. The key consideration is the softening rate of the material, which is generally below 25%. Very deep-drawn stainless steel plate material can be quenched after pre-stretching. With a high-frequency quenching machine, the softening rate can be accepted up to 40%. When designing the strip, you must communicate with customers more. It is best to The customer shows the previous mold photos or structure for reference. The empty steps are very important. Under the condition that the length of the mold allows, a moderate empty step is very helpful for the modification of the mold after the test. 3. The material belt design is an analysis of the molding process of handicrafts, most of which decide whether the mold is a success. 4. In the continuous mold design, the material lifting design is very important. If the material lifting rod cannot raise all the material belts, it is impossible to carry out the continuous production of automation technology. 5. In the design of stamping die, the selection of die material and quenching and tempering treatment and metal surface treatment (such as TD, TICN, TD time must be 3-4 days), very stretch die, if there is no TD, the surface of the die will be It's very easy to pull and burn the ball. 6. In the mold design, for the surface with smaller hole position or size tolerance, try to make adjustable inserts, which is conducive to adjustment during mold trial and production, which is very easy to achieve. The specifications of the parts should be left and right. In addition, the mold is made of adjustable inserts. Hardware, 15 years of focus on Shandong automotive hardware stamping parts, 20,000+ sets of customized mold production experience, 5000 square meters production workshop, stamping accuracy can reach ±0.01mm, 3 million punching next-day production capacity and 16 strict quality inspections. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose a rest assured!
