Description
Technical Field
[0001] This utility model relates to the technical field of bearing forging equipment accessories, and in particular to a multi-angle rotary forging head for bearing forging. Background Technology
[0002] During bearing forging, the bearing blank is heated to above the recrystallization temperature. Then, the blank is loaded into a rotary forging machine. The CNC system drives multiple sets of high-speed rotating forging heads to apply high-frequency radial forging to the blank along the circumference. At the same time, the mandrel axial feed controls the deformation amount, so that the metal flows according to the mold cavity and is gradually formed into components such as rings and rollers. Through multi-directional dynamic forging, the uniform deformation of the blank and the optimization of the internal structure are achieved.
[0003] In existing rotary forging machines, the four-die forging head installed inside the machine can perform angular forging of the bearing while rotating. This forging head comes into contact with the bearing blank under high temperature and high frequency hot forging conditions, which can lead to thermal fatigue cracking. After damage, the entire forging head needs to be replaced. However, such forging heads on the market are usually of one-piece structure, which has a high overall replacement cost. At the same time, it is not convenient to adjust the forging surface size of the forging head individually when forging bearings of different specifications. Therefore, we propose a multi-angle rotary forging head for bearing forging. Utility Model Content
[0004] The main objective of this invention is to provide a multi-angle rotary forging head for bearing forging. By disassembling the forging head, which can be driven to rotate and installed inside the rotary forging machine, into a forging head body and sub-forging bodies, and assembling and connecting the forging head body and sub-forging bodies with an assembly forging mechanism, when the forging groove surface of the sub-forging body is worn, only the sub-forging body needs to be replaced individually, unlike the need for the entire forging head to be replaced as in an integrated forging head, which significantly reduces the cost of use. At the same time, multiple sub-forging bodies with the same installation structure can be customized and uniformly assembled on the forging head body according to actual needs, improving the applicability of the forging head and effectively solving the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A multi-angle rotary forging head for bearing forging includes a forging head body and a separate forging body, and also includes an assembly forging mechanism. The assembly forging mechanism includes a top cover, a jaw groove, a jaw section, a fan head main groove, a fan head main bar, a fan head secondary groove, and a fan head secondary bar. The forging head body has symmetrically formed jaw grooves on both sides for engaging the jaw section, and the jaw section is integrally formed on the back surface of the separate forging body. A fan head main groove for engaging the fan head main bar is centrally located on the surface of the forging head body between the jaw grooves. The forging head body is integrally formed on the back side of the forging body between the claws. The surface of the forging head body between the main fan head groove and the claw groove is provided with a fan head auxiliary groove for mounting the fan head auxiliary bar. The fan head auxiliary bar is integrally formed on the back side of the forging body between the claws and the main fan head bar. One end of the forging body, the main fan head bar, the fan head auxiliary bar and the claws is integrally formed with a top cover that presses against the outer end face of the forging head body. The top cover is locked to the forging head body by bolts. The top cover and the surface of the forging head body are provided with assembly holes.
[0007] Furthermore, the remaining cover surface of the top cover away from its own assembly hole is symmetrically provided with a T-shaped hole, and a bottom screw hole is provided at the forging head body below the T-shaped hole. An internal hex bolt is screwed between the T-shaped hole and the bottom screw hole, and the head of the internal hex bolt is screwed into the large cavity of the T-shaped hole.
[0008] By adopting the above technical solution, after the top cover is placed on the forging head body, an internal hex bolt can be screwed through the T-shaped hole into the bottom hole, and then the head of the internal hex bolt can be hidden in the T-shaped hole.
[0009] Furthermore, the length of the claw groove is less than the length of the forging head body block, and an inner inclined surface is provided at the groove of the claw groove.
[0010] By adopting the above technical solution, the forging head body can be fitted with the jaw part by means of the jaw groove, and the inclined surface inside the jaw groove can be fitted with the inclined surface of the jaw part in an inward snapping manner.
[0011] Furthermore, the length of the fan head main groove is the same as the length of the forging head body, and the groove cavity of the fan head main groove is a fan-shaped groove cavity.
[0012] By adopting the above technical solution, the forging head body can use the longer fan head main groove as the main locking position, thereby adapting to the fan head main bar of the forging body for locking of the fan-shaped surface.
[0013] Furthermore, the length of the fan-head sub-groove is less than the length of the claw groove, and the fan-head sub-groove is a fan-shaped groove.
[0014] By adopting the above technical solution, the fan head secondary groove can use a short fan-shaped groove cavity to engage the fan head secondary strip to engage the fan-shaped surface.
[0015] Furthermore, a T-shaped pin groove for engaging the T-shaped pin is provided at the bottom of the claw groove, and the T-shaped pin is integrally formed on the bottom surface of the claw.
[0016] By adopting the above technical solution, when the claw part is clamped at the claw groove, the T-shaped pin at the bottom of the claw part can be inserted into the T-shaped pin groove of the claw groove for bottom connection clamping.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention separates the forging head, which can be driven to rotate and is installed inside the rotary forging machine, into a forging head body and a forging sub-body. An assembly forging mechanism is set at the forging head body and the forging sub-body for assembly and connection. When the forging groove surface of the forging sub-body is worn, only the forging sub-body needs to be replaced individually, unlike the one-piece forging head which needs to be replaced as a whole, significantly reducing the cost of use. At the same time, multiple forging sub-body with the same installation structure can be customized and assembled on the forging head body according to actual needs, improving the applicability of the forging head.
[0019] Furthermore, the forging head body and the sub-forging body are connected by clamping through the forging mechanism's claw groove, fan head main groove, and other structures. These connection positions have different lengths, which can ensure multi-point connection between the forging head body and the sub-forging body, and achieve a firm and precise assembly connection between the forging head body and the sub-forging body.
