Future metal stamping process and industry development
Time:2017/12/14 9:56:13  Browse:

Metal stamping industry is an extremely broad field of industries involved, went to all aspects of manufacturing, metal stamping in foreign countries known as sheet metal forming. In our country there is such a name. China's metal stamping industry is what it looks like, how abroad, how we go, this is all of us concerned about national issues of concern.

Metal stamping process: Metal stamping process can be divided into the separation process and the forming process (sub-bending, drawing, forming) two categories. Separation process is in the metal stamping process so that the metal stamping parts and blank along a certain contour lines separated from each other at the same time, the quality of the metal stamping part of the separation must meet certain requirements; forming process is to make metal stamping blanks in the non-destructive conditions Plastic deformation occurs, and converted into the desired shape of the finished product, but also to meet the dimensional tolerances and other requirements. In accordance with the temperature of metal stamping cold metal stamping and hot metal stamping two ways. It depends on the material strength, plasticity, thickness, degree of deformation and equipment capacity, etc., taking into account the original state of the material heat treatment and end-use conditions.

1. Cold metal stamping metal processing at room temperature, generally applicable to the thickness of less than 4mm blank. Advantages of no need to heat, no oxide skin, good surface quality, easy operation, low cost. The disadvantage is that the work hardening phenomenon, the serious loss of metal deformation ability. Cold metal stamping blank thickness requirements and fluctuations in a small area, smooth surface, no spots, no scratches and so on.

2. Hot metal stamping Metal heating to a certain temperature range of metal stamping methods. Advantages for the elimination of stress, to avoid work hardening, increase the plasticity of materials, reduce deformation resistance, reduce power consumption equipment

Die structure: Die is the separation of sheets or deformation of tools. It consists of the upper mold and lower mold in two parts. Die on the mold fixed to the slider on the punch, with the slider up and down movement, the next model is fixed in the punch table. The punches and dies are the working parts that deform or separate the blanks in the die, and are fixed to the upper die plate and the lower die plate respectively by pressing plates. Upper and lower template are equipped with guide and guide column, respectively, to guide the punch and die alignment. The guide plate and the positioning pin are used to control the feed direction and feed length respectively. The role of the unloading plate is in the metal stamping after the workpiece or blank from the punch off.
