Structural principle of metal stamping abrasive tools

The principle of metal-stamping-tool is at room temperature, using the metal-stamping-tool installed on the press to apply pressure to the material to cause separation or plastic deformation, so as to obtain a pressure processing method of the required parts. 1. The working process of the metal-stamping-tool die: The working principle of the blanking die is as follows. The upper die of the die is directly or indirectly fixed on the upper die, and it is connected with the punch slider through the die handle. The parts fixed on the lower die constitute the lower die of the mould, and are fixed on the workbench of the punch press by means of a pressing plate. The upper metal-stamping-tool and the lower metal-stamping-tool are guided by guides and guides. When working, the strip material is fed and positioned against the stopper. When the upper metal-stamping-tool descends with the slider, the unloading material first presses the sheet material, and then the convex punches the material on the concave surface to obtain the workpiece. At this time, the workpiece is stuck between the punch and the top block, and the waste is tightly bound on the punch. When the upper die rises, the workpiece is ejected from the cavity of the die by the force of the spring against the top plate; at the same time, the waste hooped on the punch is removed by the spring force of the unloading plate, and then the workpiece is taken away. Complete the entire blanking process. Then the strip is fed into a step, and the next punching and blanking process is carried out, and so on. 2. Classification of metal-stamping-tool dies: 1. Open die: simple structure, small size, light weight, easy manufacturing, low cost, but low life, poor precision, suitable for low precision requirements, simple start, small batch or trial production punching cut pieces.2. Guide plate type: The precision is higher than that of the open die, and it is suitable for blanking parts with simple opening and small workpiece size. It is required that the stroke of the press is not greater than the thickness of the guide plate. 3. Guide column type: Guide column guide ensures uniform blanking gap, high dimensional accuracy of punched workpiece, long service life of mold, easy installation, suitable for mass production. 4. Continuous mold: The strip material requires precise positioning, so that the mutual position accuracy of the inner hole and the shape can be guaranteed. High productivity, with a certain punching precision, suitable for mass production. 5. Composite mold: The inner and outer shapes of metal-stamping-tool parts have high position accuracy, which is suitable for mass production.、
