Features of cold heading machine

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

2. The machine body is cast by adding alloyed ductile iron 500, with high tensile strength and good wear resistance.

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

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

5. The cutting system adopts a guide plate to drive the cutting bar, the guide plate reciprocates, and the cutting force is transmitted linearly, with large force and stability and good dynamic balance.

6. The clamp system can be flipped or translated by 180 degrees. Conducive to the arrangement of the molding process.

Introduction to Cold Heading Process

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

(2) High-quality metal materials with good "plastic deformation" must be selected, such as riveting steel, which has strict standards for chemical composition and mechanical properties.

(3) The cold heading bolt and nut forming machine has multiple models and multiple series models. The equipment has reliable performance, high efficiency and stable product quality.

(4) The product has high forming and upsetting force, the configuration power is there, and the equipment investment is large at a time. Therefore, the production specifications below M24 are the most economical.

(5) It has good surface quality and high dimensional accuracy. Because of the cold work hardening in the upsetting process, the amount of deformation should not be too large. Reduce cracking.

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

The history of cold heading machines

The earliest cold heading machine in the world originated from Germany. At that time, the purpose of developing the cold heading machine was mainly for the mass production of bullet shells during World War II.

Introduction to the adjustment steps of the cold heading machine

The cold heading machine adopts cold dial elements or rod-shaped materials, which become lightweight hexagonal nuts after tapping. The cold heading machine is horizontal, and the stations are arranged horizontally. The whole process of feeding, cutting, clamping, and cold heading is carried out automatically.

 

Steps to adjust the cold heading machine:

1. Adjustment steps for hardware connection on site. Install the proximity switch on the device and connect all components according to the electrical schematic diagram.

2. Reset the device. Press the two reset switches on the counter operation panel to reset the preset number and processing number.

Introduction to the performance of metal materials in the cold heading machine

Features of the cold heading machine: It adopts a two-stage gear transmission system with high transmission efficiency and large transmission torque. The crankshaft is connected to the main body and the impact connecting rod through a high wear-resistant alloy copper tile. It has high carrying capacity, long service life and low maintenance cost.

Performance introduction of metal materials in cold heading machine:
The ability of metal materials to adapt to heat and cold processing is called processability, which is called processability. Materials with good process performance have higher process tolerance and lower manufacturing costs.
Forging performance: The blanks of key parts usually undergo a forging process. The ability of a material to withstand forging and forming is called forgeability. Metal forging performance can be measured by its plasticity and resistance to deformation (strength). If the amount of deformation is large and there are no cracks, the forgeability of the metal is good. Metal forging performance depends on material composition, structure and processing conditions.
Welding performance: Metal materials use specific welding processes, welding materials and structural forms, and have the ability to weld high-quality joints called metal weldability. The main factor affecting the welding performance of steel is the carbon content of the steel. The role of other alloying elements in steel is relatively small.
Mechanical properties: refers to the ability of metal materials to resist and accept external force deformation. Strength is a measure of the ability of a material to resist plastic deformation and fracture caused by external forces. Plasticity is a measure of the ability of a material to withstand external force and deformation.
