A forging method for forming a metal bar to be upset (often partially upset) at a normal temperature using a mold. Usually used to make heads for screws, bolts, rivets, etc. It can reduce or replace cutting. A forging method for forming a metal bar to be thickened (often partially upset) at a normal temperature by using a mold is described. Usually used to make heads for screws, bolts, rivets, etc. It can reduce or replace cutting.
The forging material can be copper, aluminum, carbon steel, alloy steel, stainless steel "target=_blank> stainless steel and titanium alloy, etc., the material utilization rate can reach 80-90%. The cold heading is carried out on a special cold heading machine, which is easy to realize. Continuous, multi-station, automated production. On the cold heading machine, the processes of cutting, hoeing, accumulation, forming, chamfering, twisting, shrinking and trimming can be completed sequentially. The production efficiency is high, up to 300 pieces/min. Above, the diameter of the largest cold heading workpiece is 48 mm. The bar material is automatically fed to a certain degree by the feeding mechanism, the cutting mechanism cuts it into a blank, and then the clamp conveying mechanism sequentially sends it to the accumulation pressing and punching station for cooling.镦 Forming.
This technology is a type of cold forming, which is a processing method of punching, bending, stretching, etc. without heating. The cold forming process includes cold heading, cold rolling, die forging, and the like. Multi-station bolt cold heading machine
Advantages The main advantages of cold formed steel structures:
1. Compared to thicker hot-rolled sections, cold-formed steel can be machined to accommodate smaller loads and shorter spans.
2. An unusual cross-sectional shape can be economically obtained by cold forming processing to obtain a satisfactory strength-to-weight ratio.
3, considering the compact type of packaging and transportation, can produce nestable sections.
4. There is no expansion and deformation under the action of environmental gravity.
