What are the requirements for the production of automotive stamping parts processing molds?
The use of high-speed cutting technology for automotive stamping parts processing molds has a great effect on reducing production time and improving production efficiency, but ordinary high-speed cutting requires a milling speed of more than 40,000 revolutions per minute. All parts of a high-speed machining lathe must be able to respond to the joint operation to make the machine work normally. What are the detailed requirements for automobile Stamping Die production?
Processing characteristics of automobile stamping parts
- 1. Since the high-speed cutting lathe is controlled by a microcomputer program, it is necessary to have a central processing unit and large-capacity storage equipment to quickly process a large amount of data; it has the ability to transmit data and web pages quickly; it has the function of error compensation, Including measurement error compensation, quadrant error compensation, and thermal error compensation.
- 2. The drive system requires a relatively large feed rate and acceleration, which can generally reach an acceleration of 20-30 meters per minute and 20-40 meters per second square.
- 3. The main axis of a high-speed airport. Since stamping dies need to be milled at a very fast speed in high-speed cutting, the speed of the spindle should also keep up with it. Generally speaking, it needs to be adjustable from 10,000 to 100,000 per minute, and has the function of rapid acceleration and rapid and precise parking. Therefore, the bearing layout of lathes generally adopts hydrostatic pressure, aerostatic pressure, and suspended magnetic suspension.
- 4. The processing of automobile stamping dies is carried out by milling tools. Milling without tens of thousands of revolutions tests the hardness and wear resistance of the tools. Therefore, the material of the tool must be cemented carbide, polycrystalline diamond, etc. At the same time, the positioning of the tool must be accurate, and the error is controlled within 0.001 mm.
