Cold heading machine — the core equipment in bolt production

Cold heading machine is a forging machine for upsetting metal bar material at normal temperature, mainly used to make bolts, nuts, nails, rivets and steel balls and other parts. The following is a detailed introduction to the cold header:

1.The working principle
The working principle of the cold heading machine is mainly transmitted by the belt wheel and the gear, the linear movement is carried out by the crank connecting rod and the slider mechanism, and the plastic deformation or separation of the embryo of the processed parts is made by the punch and the concave die. When the main motor drives the flywheel to rotate, it drives the crankshaft connecting rod mechanism to make the slider move up and down. When the slider goes down, the metal bar material placed in the mold is impacted by the punch fixed on the slider, causing it to undergo plastic deformation and fill the mold cavity, so as to obtain the required shape and size of the forging.

2. Features
1.High efficiency: The cold header can efficiently carry out continuous, multi-station and automated production, significantly improving production efficiency.

2.High precision: Due to the use of mold forming, the cold heading machine machining parts with high dimensional accuracy and good surface finish.
3.High material utilization rate: the material utilization rate in the cold heading process can reach 80 ~ 90%, reducing material waste.
4.Strong adaptability: Can process a variety of metal materials, such as copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy.
5.Strong structure: The key components of the cold header, such as the crankshaft, body, impact connecting rod, etc., are cast with high wear-resistant alloy, with large bearing  capacity and long service life.
6.Equipped with advanced devices: equipped with frequency control device, pneumatic clutch brake, fault detection device and safety protection device, etc., to improve the safety and stability of the equipment.

3. Application field
Cold heading machine is widely used in fastener industry, auto parts manufacturing, construction and building materials industry and other fields. For example, it can be used to produce auto parts such as bolts, nuts, screws, pins and bearings; Construction materials such as expansion screws, flat head nails, rivets and anchor bolts can also be produced.
