Automatic cold heading machine is a high-efficiency, automatic professional machine tool in forging machinery. Cold heading process and automatic cold heading machine are important means for the standard parts industry to produce various bolts, screws, rivets and nuts. Due to the advanced nature of the cold heading equipment itself and the superiority of the cold heading process, it can be widely used in various fields of the national economy, such as: aviation, ships, machinery, rail transit, automobiles, motorcycles, bicycles, sewing machines, construction, Processing and production of fasteners and special-shaped non-standard parts in furniture, light industry, daily necessities and other industries.
Working principle of cold heading machine:
The cold heading machine of the cold heading machine is a forging method that uses a mold to upset (usually a local upsetting) a metal bar at room temperature. It is generally used to make the heads of screws, bolts, rivets, etc. The materials used can be aluminum, copper, carbon steel, stainless steel, alloy steel, and titanium alloys. Wire drawing allows the wire material to enter the machine, and the processes of material cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and edge trimming can be completed in sequence on the cold heading machine. The cold heading machine is divided into molds, multi-station, The production efficiency is high, and the feeding accuracy and cutting speed are achieved, and then sent to the accumulating and pressing station and punching station for cold heading forming by the clamp conveying mechanism.
Advantages of cold heading machine：
1. Compared with ordinary machines, cold heading machines can produce more special screws, and the screws produced are more accurate. This will depend on where the screws are used, because some places are relatively strict.
2. Compared with thicker hot-rolled steel, cold-formed steel can be processed to apply smaller loads and shorter spans.
3. Unusual cross-sectional shapes can be obtained economically through cold forming, and a satisfactory strength-to-weight ratio can be obtained.
4. Equipped with fault detector and safety protection device, it will stop automatically when the equipment fails, giving maximum protection to equipment and molds.
5. The feeding box is equipped with a thrust device to improve the feeding accuracy.
The above is the working principle and advantages of the cold heading machine. For more information about forging equipment, you can always consult Henan Jinzhen—the forging expert around you.
