Cold Forging Process In Electrical Products And Motor
Cold forging is a forming process in which workpieces are processed at room temperature by using a highly specialized cold extrusion hydraulic press. The material is subjected to high compression forces to produce plastic deformation to form new products. Cold forging technology provides many benefits to both manufacturers and users.
This is one of the forging methods being using in so many industries. One of these industries is the manufacturing of electrical products and accessories. From motor housing, LED lampshades to electronic cigarette housings, most of them are today being cold forged. There are many accessories for electrical and motor products including:
Motor shaft
The motor shaft is used as a part that bears the rotation of the motor or transmits the torque from the prime mover to the motor. It is the part that also transmits the torque from the motor to the part being dragged. Its strength and matching accuracy directly determine whether it can be used under normal conditions for reliable operation.
In addition, instantaneous over-torque conditions such as sudden load or abnormal load are inevitable. But for any of the strength and toughness that exceeds the capacity limit of the motor shaft, the consequences can be devastating. Therefore, customers should be very picky about the shaft when buying.
Cold forged products have high strength and features of high precision. This makes cold forging the best choice for the motor shaft forming process.
Radiators
Cold forging one-piece radiator is produced by placing AL1070, AL6063, or AL1050 aluminum in a precision cold forging die and plastically deforms it by extrusion by a press. Only the arcs of the ends and blades need to be processed by CNC lathes. It saves valuable raw materials and processing time and reduces production costs.
The cold-forged radiator currently produced by CXIN Forging is made of AL1070, AL6063, or AL1050 aluminum, and the internal structure is denser than other processes. The actual thermal conductivity of the finished forging is higher than that of pure aluminum, which is 226W/mk. For the alloy aluminum AL6063, the thermal conductivity is 180W/mk, while the thermal conductivity of ordinary die-cast aluminum A380 is only 96W/mk.
The greater the thermal conductivity, the faster the released heat can be conducted, which is more conducive to the overall heat dissipation of the electrical appliance.
Copper Terminals
Copper terminals are conductive contacts commonly used in power control cabinets and are usually made of copper. The traditional process is mostly extruded copper profile + machining manufacturing. The disadvantage of this process is that the cost of the copper profile is higher in small batches, and the machining process has low material utilization, low processing efficiency, and high processing equipment cost.
Using the cold forging and cold extrusion composite process, compared with the process of using copper profiles + machining, the material utilization rate is increased by 20%. The production efficiency is improved, the production cost is reduced, the dimensional accuracy is good, and the appearance quality is good.
