The invention discloses a ball pin cold heading device and a heading process thereof. The ball pin cold heading device comprises a cutting mechanism, a feeding mechanism, a conveying mechanism and a plurality of moulds, wherein the feeding mechanism corresponds to the cutting mechanism in position, the conveying mechanism moves between the feeding mechanism and the moulds to convey materials, and the moulds are composed of a first mould for strongly binding the rod portions of wire rods, two second moulds for forming the head portions and the flanges of the wire rods, and a third mould for forming the ball joints of the wire rods; the third mould comprises a third punch mould and a third main mold, the inside of the third main mould is provided with a clamp mould corresponding to a ball pin. According to the ball pin cold heading device, the ball joint portion of the ball pin is formed through the clamping mould of the third mould, the material utilization rate reaches 100%, streamline fracture of materials can be avoided, and the strength of the products can be improved; the wire rods do not need machining after being cold-headed, the production efficiency can be effectively improved, the production cost of the ball pin can be effectively reduced.
Description
technical field [0001] The invention relates to the field of mold processing, in particular to a ball stud cold heading device. Background technique [0002] The ball stud is an important connecting part of the car and tractor, and it is also a key component to ensure the stability of the car's handling, ride comfort, safety, and the correct and accurate driving of the car. Therefore, there are high requirements for its physical and mechanical properties. Because the ball stud pin is thin in the middle and large at both ends, ordinary molds cannot be formed. In the past, it was mainly processed by cutting technology. The strength and hardness of the material cannot be guaranteed. In actual use, parts are often damaged and need to be replaced constantly. Phenomenon. [0003] There is an existing ball stud production process, which is completed by subjecting the bar to CNC (numerical control machine tool) full processing (that is, a processing process that accurately removes...
