What are the advantages and uses of multi-station cold heading machines

Cold heading process: The forging method of thickening the top of rod or wire with a cold heading machine at room temperature, inCold heading machineThe upper part can complete the cutting, upsetting head, accumulation, forming, chamfering, wire rubbing, shrinking diameter and edge cutting processes in sequence. The bar material is automatically fed to a certain length by the feeding mechanism. The cutting mechanism cuts it into a blank, and then is sent to the accumulation and punching stations by the clamp conveying mechanism for forming. It is mainly used to make parts such as bolts, nuts, iron nails, rivets and steel balls. The forging materials can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloys. The following briefly introduces the advantages of multi-station cold heading machine equipment:
1. Structural characteristics of multi-station cold heading machine
(1) The connection between the crankshaft and the body and the impact connecting rod are connected by high wear-resistant alloy copper tiles, with a large load-bearing capacity and a long service life.
(2) The body is made of ductile iron with alloy added, with high tensile strength and good wear resistance.
(3) A 2-stage gear transmission system is adopted, with high transmission efficiency and large transmission torque.
(4) Equipped with a pneumatic clutch brake to reduce motor power and energy consumption.
(5) The material cutting system uses a guide plate to drive the cutting rod, the guide plate reciprocates, and the cutting force is transmitted in a straight line, with large and stable force and good dynamic balance.
(6) The multi-station cold heading machine uses a closed clamp to convey the workpiece, and the clamp system can be flipped or translated, which facilitates the formation process arrangement.
(7) Equipped with a frequency converter speed regulation device, which can adjust the speed within a certain range without limit.
(8) Equipped with a fault detector and safety protection device, and the equipment will automatically stop when the equipment fails, giving the equipment and tool molds great protection.
(9) Install a thrust-resisting device in the feeding box to improve the feeding accuracy.
(10) The lubrication system oil circuit design is simple and efficient, and can effectively protect the punch rod and workpiece on the basis of ensuring circulation and filtration.
2. Process characteristics of multi-station cold heading machine
(1) Apply a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and mold according to the specified shape and size.
(2) Have good surface quality and high dimensional accuracy.
(3) The cold heading process applies to fasteners of large batches and various specifications.
3. Selection of raw materials by multi-station cold heading machine
(1) The cold heading machine is mainly manufactured based on the metal plastic deformation theory, and when selecting metal materials, it is also very high-quality for its materials and has very strict standards, especially the chemical composition and mechanical properties of riveted screw steel.
(2) The cold heading machine has good surface quality and very high dimensional accuracy during production. It has good cold hardening during the upsetting process, so it can maintain a good deformation amount and not cause too much deformation, thereby reducing the cracking of the workpiece.
4. Selection of cold heading oil for multi-station cold heading machines
(1) It has excellent extreme pressure lubrication performance, high temperature resistance, extreme pressure wear resistance, rust resistance and high temperature oxidation resistance. It improves the accuracy and finish of the processed parts, can prevent mold sintering, meets the multi-station molding of standard parts and non-standard parts, and can be fully qualified for cold heading stainless steel workpieces.
(2) The oil smoke and "drift fog" can be reduced to a low limit to meet the strict requirements of nuts containing reinforced molds.
(3) It has good performance for workpieces with relatively large deformation, such as hollow, high-strength bolts, sleeves, stainless steel hollow, semi-hollow rivets, etc.
(4) Can effectively protect punch rods and molds and extend service life.
(5) Good heat dissipation effect, avoiding excessive local temperature of the workpiece and mold during cold forming.
(6) High temperature resistance, good performance, and is not easy to produce sludge, low odor, low smoke, and protect the operating environment.
(7) It has certain anti-rust properties and can meet the anti-rust requirements between processes.
(8) Carbon steel molding that can meet the harsh cold heading stainless steel molding and large-variant carbon steel molding.
