Zhuhai hardware stamping parts, how to design stamping dies + 20000+ sets of mold custom design experience

The hardware responsible for the production of metal stamping parts in Zhuhai has said about several important experiences in stamping die design. Knowing these is the master of stamping die design. The following Xiaoshuo will take everyone to understand: 1. Before designing the material belt, you must master the dimensional tolerances of the parts, material characteristics, high-speed punching capacity, high-speed punching cabinet countertops, SPM (per minute), and Material orientation, feeding aspect ratio, mold thickness regulation, material usage 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-drawing. With a high-frequency quenching machine, the softening rate can be accepted up to 40%. When designing the strip, you must communicate more with the customer, and the customer is required to show it For reference from previous mold photos or structures, empty steps are very critical. Under the condition that the length of the mold allows, a moderate amount of empty steps is very helpful for mold modification after mold trial. 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 molds, the selection of mold materials and quenching and tempering treatment and metal surface treatment (such as TD, TICN, TD time must be 3-4 days), very stretch molds, if there is no TD, the surface of the mold It will be 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. Regarding the word mark, it is stipulated that it can be dismantled on the side of the punch, and the time is wasted by dismantling without the upper mold. 7. When designing the radon bomb, it is designed according to the working pressure analyzed by CAE. It is not necessary to design an oversized radon bomb to avoid product cracking. The general situation is: low working pressure, product wrinkles, too much pressure, product cracking. To deal with product wrinkles, you can choose to partially lift the drawbeads, first add the drawbeads to fix the plate in the immobile position, and then pull it to reduce the wrinkles. Hardware, 15 years of focusing on Zhuhai metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly processing of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy up to 0.01 mm, 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 to rest assured!
