The characteristics of the cold heading machine: two-stage gear transmission system, 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 load carrying capacity, long service life and low maintenance cost.
The performance of metal materials in cold heading machine is introduced:
The ability of metal materials to adapt to hot and cold processing is called workability, called workability. Materials with good process properties have higher process tolerance and are less expensive to manufacture.
Forging performance: The blank of the key parts usually goes through the forging process. The ability of a material to withstand forging and forming is called malleability. Metal forging performance can be measured by its plasticity and deformation resistance (strength). If the amount of deformation is large and there is no crack, the forgeability of the metal is good. Metal forging performance depends on material composition, structure and processing conditions.
Welding performance: Metal materials adopt 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 steel. Other alloying elements play a relatively minor role in steel.
Mechanical properties: refers to the ability of metal materials to resist and accept external force deformation. Strength is a measure of a material's ability to resist plastic deformation and fracture caused by external forces. Plasticity is a measure of the ability of a material to withstand deformation by external forces.
Introduction to the adjustment steps of the cold heading machine
The cold heading machine uses cold dial elements or rod-shaped materials, which become lightweight hexagonal nuts after tapping. The cold heading machine is horizontal, and the work stations are arranged horizontally. The whole process of feeding, cutting, clamping and cold heading is automatic.
The adjustment steps of the cold heading machine are introduced:
1. Adjustment steps of hardware field connection. Install the proximity switch on the device and connect all components according to the electrical schematic.
2. Reset the device. Press the two reset switches on the counter operation panel to reset the preset number and the process number.
3. One-touch protection. When the key switch (SA1) is turned, the key operation on the counter operation panel is invalid.
4. Parameter setting. By setting the acceleration and deceleration time parameters (2202) according to the requirements of the user unit, the starting frequency of the frequency converter is increased from 1Hz to 50Hz (I. e., the motor speed is increased from 0r/min to 1500r/min) to 3 seconds.
5. Processing test. Start the machine first in manual mode to machine the part. The device will operate normally and will switch to automatic mode. Set the total number of processed parts on the counter to 30 and start the device. When the number of processed parts reaches 30, the equipment will stop running. In manual and automatic modes, turning the potentiometer on the governor will change the processing speed of the part, and the speed of each cycle will be displayed on the digital display.
Five. Emergency stop, please. Press the emergency stop button on the operation panel of the control panel to stop the device. When the total power is removed, the counter data remains unchanged. Then, when the power is turned on again, the parts will be processed and stop running until the preset number is reached.
History of cold heading machines
The world's earliest cold heading machine originated in Germany. At that time, the purpose of developing the cold heading machine was mainly to manufacture a large number of bullet casings during the Second World War.
Introduction of cold heading process
(1) According to the theory of metal plastic change, a certain pressure is applied to the metal blank at room temperature to make it produce plastic change in the mold cavity and form according to the specified shape and size.
(2) must choose high-quality "plastic change" good metal materials, such as riveted screw steel, its chemical composition and mechanical properties have strict standards.
(3) cold heading bolt, nut forming machinery has many models, many series of models. The equipment has reliable performance, high efficiency and stable product quality.
(4) The product forming and forging force is large, the configuration power is in, and the equipment is invested at one time. Therefore, it is economical to produce specifications below M24.
(5) It has better surface quality and higher dimensional accuracy. Due to the presence of cold hardening in the upsetting process, the amount of deformation should not be too large. Reduced cracking.
(6) The cold heading process is applicable to products with large quantities and various specifications, so as to reduce costs.
Characteristics of cold heading machine
1. The connection between the crankshaft and the body and the impact connecting rod is made of high wear-resistant alloy copper tile, which has large bearing capacity, long service life and low maintenance cost.
2. The body is made of ductile iron 500 cast with alloy, 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 consumption.
5. The cutting system adopts the guide plate to drive the cutting rod, the guide plate reciprocates, the cutting force is transmitted in a straight line, the force is large and stable, and the dynamic balance is good.
6. The clamp system can be turned over or translated 180 degrees. Conducive to molding process arrangements.
7. Equipped with frequency conversion speed regulation device, it can speed regulation stepless within a certain range.
8. Equipped with fault detector and safety protection device, automatic shutdown when equipment fails, giving greater protection to equipment and tools.
9. The feeding box is equipped with thrust device to improve the feeding accuracy.
