6 main features of cold heading machine process

Cold heading machine is a special cold forging machine mainly used for mass production of screws, nuts, bolts and other fasteners.

The world’s earliest cold heading machine originated from Germany.

6 main features of cold heading machine process

(1) According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at normal temperature to cause plastic deformation in the mold cavity and molding according to the specified shape and size.

(2) Metal materials with good “shaping” must be selected, such as rivet steel, which has strict standards for its chemical composition and mechanical properties.

(3) There are many models and series of cold heading bolt and nut forming machines. The equipment has reliable performance, high efficiency and stable product quality.

(4) The product forming and upsetting force is large, the configuration power is high, and the equipment investment is large at one time. Therefore, it is economical to produce products with specifications below M24.

(5) It has good surface quality and high dimensional accuracy. Because there is cold work hardening during the upsetting process, the deformation should not be too large.

(6) The cold heading process is suitable for products with large batches and various specifications, so as to reduce costs.

1. The connections between the crankshaft, the engine body and the impact connecting rod are all made of highly wear-resistant alloy copper tiles, which have large bearing capacity, long service life and low maintenance costs.

2. The machine body is cast from ductile iron 500 with added alloy, which has high tensile strength and good wear resistance.

3. It adopts a two-stage gear transmission system with high transmission efficiency and large transmission torque.

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

5. The cutting system uses a guide plate to drive the cutting rod. The guide plate reciprocates and the cutting force is transmitted linearly. The force is large, stable and has good dynamic balance.

6. The clamping system can be flipped or translated 180 degrees. Conducive to molding process arrangement.

7. Equipped with a frequency conversion speed regulating device, which allows no speed regulation within a certain range.

8. Equipped with fault detector and protection device, the machine will automatically stop when the equipment fails, giving maximum protection to the equipment and tools.

9. The feeding box is equipped with a thrust device to improve feeding accuracy.
