Stamping die wire drawing machine is very simple. The standard equipment on the market is the carrier of the mold. There are differences in the size of hot stamping machines and hot stamping machines. Taking into account the size of the medium pressure product and the thickness of the material, presses of different tonnage should be selected
The shape and precision of the parts play a decisive role in the stamping die and are very important. The accuracy of the mold determines the accuracy of the parts. So there are many structures and types of metal molds.
From the point of view of the stamping process of metal molds, the commonly used molds should have the following processes:
1. The blanking die separates the material from the die along a closed or open contour. Such as blanking die, punching die, cutting die, blocking die, blocking die, blocking die, etc. These have the effect of blanking, so they are called blanking dies.
2. The drawing die is a die that draws the material into an open hollow part or further changes the shape and size of the hollow part.
3. The forming die is a die that directly copies the blank or semi-finished product according to the shape of the punch and the die, and the material itself only produces partial plastic deformation. Such as bulging dies, shrinking dies, flaring dies, forming dies, flanging dies and forming dies
4. Riveting die is to use external force to connect or connect parts in a certain order and way, and then form a whole.
From the point of view of the metal stamping process, the mold can have the following categories:
1. The punching die is a relatively simple die in the die, one can be formed, as long as the punching process is completed in one action of the punching machine.
2. The deep drawing die only needs one process and action. In one action of the punch, two or more metal stamping dies are done simultaneously in the same process.
3. Forming molds, some main molds are also called progressive molds, which are a more difficult type of mold. Choose automatic feeding, choose two or more processes. In the middle bed, two or more stamping dies are completed in different processes under the effect of one press.
4. Handling method: Combined with the characteristics of single-process die and continuous stamping die, the robot handling system is used to complete the rapid handling in the die, which can greatly improve the production efficiency of products, reduce production costs, and save material costs. Stable and reliable product quality is the characteristic of mold maintenance.
With the widespread use of metal molds, the requirements for parts and molds are getting higher and higher. On this road, China still has a long way to go, facing higher challenges and breakthroughs.
