Cold heading machineis specialized equipment for mass production of nuts, bolts, and other fasteners. The early cold heading machines in the world originated in Germany. The main purpose of development at that time was for the mass production of shell casings during World War II.Cold heading machineThe main purpose of development at that time was for the mass production of shell casings during World War II.1)According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature, causing the mold cavity to undergo plastic deformation and forming according to specified shapes and sizes.2)High-quality metal materials with good plastic deformation must be selected, such as riveted threaded steel, which has strict standards for chemical composition and mechanical properties.3)Cold heading bolt and nut forming machines come in various models and series. This equipment is reliable in performance, high in efficiency, and stable in product quality.4)The forming and upsetting force of the product is large, with power configuration, and the initial investment in equipment is high.5)The surface quality is good, and the dimensional accuracy is high. Due to cold working hardening during the upsetting process, the amount of deformation should not be too large to reduce cracking.6)The cold heading process is suitable for large quantities and multiple specifications of products to reduce costs.

Modern cold heading machines have developed from simple dual-station to multi-station. This equipment is easy to operate, with a simple process, and can be designed as a cold heading machine that pushes out elongated specifications.

The difference between cold forging machines andCold heading machinelies in the process. That is, the difference between forging and heading. Forging is a processing method that applies external force to parts to change their shape. Heading is a type of forging, which is a method of shortening the length of parts and increasing their diameter.

Characteristics of cold heading machines:

1. The crankshaft, machine body, and impact connecting rod are all connected with high wear-resistant alloy copper bearings, which have a large load capacity, long service life, and low maintenance costs.

2. The machine body is made of ductile iron with added alloys500, which has high tensile strength and good wear resistance.

3. A two-stage gear transmission system is used, which has high transmission efficiency and large torque transmission.

4. Equipped with a pneumatic clutch brake to reduce motor power consumption.

5. The cutting system uses a guide plate to drive the tool rod, with the guide plate moving back and forth, allowing cutting force to be transmitted linearly, providing great stability and good dynamic balance.

6. The clamping system can be flipped or translated180to facilitate the arrangement of the forming process.

7. Equipped with a variable frequency speed regulation device, which can infinitely adjust the speed within a certain range.

8. Equipped with a fault detector and safety protection device, which automatically shuts down the equipment in case of a fault, providing maximum protection for the equipment and tools.

9. A thrust device is installed in the feed box to improve feeding accuracy.
