Description

Technical Field

[0001] The utility model relates to the field of forging die processing, in particular to a processing fixture for star-shaped sleeve blocks. Background Art

[0002] The star sleeve is an important component in the transmission system of a car. In the prior art, it is generally forged by axial demolding, and then the outer ball and inner groove are machined to remove the excess. The star sleeve formed by this forging method has a low material utilization rate and a large machining allowance. Therefore, the forging die structure is improved, and the radial demolding method is used for forging production, which can achieve the goal of high material utilization rate and small machining allowance.

[0003] The radial demolding die generally uses an embedded block as the forging die cavity, with the front of the block being a special-shaped cavity and the back being an inclined surface with a demolding angle. This type of die is difficult to clamp during subsequent processing.

[0004] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the utility model discloses a star-shaped nesting block fixture, and the specific technical solution is as follows:

[0006] The utility model provides a star-shaped sleeve insert block fixture, comprising an insert block fixture platform, a star-shaped sleeve insert block, a fixed pressure block and a fixed screw rod.

[0007] The top of the insert fixture table is provided with a fixing groove inwardly from the side wall thereof, and the fixing groove is narrow at the top and wide at the bottom.

[0008] The star-shaped insert block is arranged in the fixing groove.

[0009] The fixed pressure block is fixed at the starting end of the fixed groove on the side wall of the insert fixture, and the fixed pressure block is also provided with a threaded hole connected to the fixed groove.

[0010] One end of the fixing screw rod passes through the threaded hole and extends into the fixing groove to abut against the star-shaped insert block.

[0011] Furthermore, the bottom of the fixing groove is set to be a slope that matches the back of the star-shaped nesting block, the front of the star-shaped nesting block remains horizontal, and the fixing groove is gradually extended upward from the starting end.

[0012] The above structure ensures that the mold can be placed horizontally on the work surface, and the insert can be pushed by a screw to clamp it.

[0013] Furthermore, inwardly protruding steps are provided on both sides of the top of the fixing groove, and long inwardly recessed bayonet holes are provided on the corresponding waists on both sides of the star-shaped nesting block. The bayonet holes are parallel to the steps, and the shapes of the bayonet holes and the step contact surfaces match and engage with each other.

[0014] The above structure limits the upward movement of the insert and prevents it from leaving the fixture table.

[0015] Furthermore, the cross section of the star-shaped nesting block is in a fan-shaped shape, and the fixing groove is configured as a dovetail groove having the same fan-shaped angle as that of the star-shaped nesting block.

[0016] The above structure facilitates the assembly of the insert into the fixing groove.

[0017] Furthermore, the step protrudes from the dovetail groove structure.

[0018] The above structure enables the bayonet on the insert to be snap-fitted onto the step.

[0019] The utility model has the following beneficial effects:

[0020] 1. The star-shaped nesting block fixture provided by the utility model has a simple structure and an ingenious design, and is easy to manufacture and popularize.

[0021] 2. The star-shaped insert block fixture provided by the utility model can realize rapid fixation and positioning of the mold on the processing table through rapid assembly of the insert block and the tooling fixture table.

[0022] 3. The star-shaped insert block fixture provided by the utility model is designed with a contoured fixture table according to the star-shaped insert block, so that the insert block's special-shaped cavity is accurately and horizontally placed on the processing table, and then a stabilizing screw is used to limit the movement of the insert block.

[0023] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
