Cold Heading Machine Description


The processing and forming of metal parts of cold heading machine originally requires mechanical multi process cutting, while the cold heading method can minimize cutting or no cutting, and then directly form into the shape and size people want, which not only saves a lot of materials, but also greatly improves the production efficiency and significantly improves the mechanical strength. The multi station automatic cold heading machine uses the cold heading method to process optical disc components or bars. After tapping, it automatically upsets various hexagon nuts, that is, grinding the standard hexagon nuts. The reinforcement bar is transported through the roller driving device, and then transported, cut, press ball, press angle, hydraulic pressure and punch press. Several processes are completed by one machine. The cold heading station is horizontally arranged, which has the characteristics of accurate positioning, stable operation and convenient maintenance, and is suitable for large-scale production of manufacturers. Multi station automatic cold heading machine is a special equipment for producing hexagon nuts and some non-standard parts. Single side S-shaped plate is more stable and stronger, and the time is adjustable.

Multi station cold heading machine has good surface quality and high dimensional accuracy. Because of the cold work hardening in the upsetting process, the deformation is not too large and the crack is reduced. Multi station cold heading machine has high forming power, fixed power and electric power. Therefore, the manufacturing standard of multi station cold heading machine is economical. Multi station cold heading machine mainly includes screw cold heading machine and nut cold heading machine. The technical principle of multi station cold heading machine is mainly used to make bolts, nuts, nails, rivets, steel balls and other parts. The cold heading machine is convenient to realize continuous, multi station and active production.

Safety operation procedures for automatic multi station cold heading machine:

1. It is forbidden to wear gloves to operate the cold heading machine.

2. Before start-up, carefully check whether the fasteners of the equipment are locked and whether the safety protection devices are in good condition, and regularly check during work to prevent loosening due to violent vibration and accidents.

3. After the equipment is adjusted, pull the flywheel first to check whether the operation of each mechanism is normal. The motor can be started only after the lever for pulling the vehicle is removed. It is forbidden to start the motor while pulling the car.

4. All faults shall be eliminated before start-up, and trial upsetting can be carried out after short space-time rotation.

5. During the operation of the equipment, the operator shall stand in a safe position. It is strictly prohibited to pick up the workpiece at the concave convex die. The product can only be viewed at the lower end.

6. When replacing products, the mould and punch must be carefully adjusted, and the components must be carefully checked for normal operation.

7. In the production process, if there is a fault, it must be stopped immediately to find out the cause and eliminate the hidden danger. When the brake fails, it is strictly prohibited to drive.

8. The safety board (bumper) must be equipped with protective devices to avoid breakage and accidents. All protective devices shall not be disassembled or lost arbitrarily.

Structural features and advantages of multifunctional screw and nut cold heading machine:

1. The crankshaft is connected with the engine body and impact connecting rod with high wear-resistant alloy copper tile, which has large bearing capacity, long service life and low maintenance cost.

2. The body is made of nodular iron 500 with alloy added, 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 brake to reduce motor power and energy consumption.

5. The cutting system adopts the guide plate to drive the cutter bar. The guide plate moves back and forth, and the cutting force is transmitted in a straight line. The force is large, stable and has good dynamic balance.

6. The clamp system can be turned or translated 180 degrees. It is conducive to the arrangement of forming process.

7. Equipped with frequency conversion speed regulation device, it can adjust speed steplessly within a certain range.

8. Equipped with fault detector and safety protection device, the equipment will stop automatically in case of equipment failure, giving maximum protection to the equipment and tooling.

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