However, the precision and improper design of the die may cause the retainer to be deformed in the subsequent riveting process, resulting in insufficient strength of the retainer.

[0050] Based on the above research, the embodiment of the present disclosure provides a retainer side punch die.

[0051] The above-mentioned defects are the results of the inventors' practice and careful research, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions of the inventors to the present disclosure.

[0052] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0053] Referring to Figure 1 andFigure 2 The present embodiment of the present disclosure provides a side punching die for a retainer, comprising: an upper die 100 and a lower die 200; the lower die 200 is provided with a die cavity 300 for placing a retainer 400, and a plurality of punching portions 310 adapted to move radially are arranged in the die cavity 300; wherein the upper die 100 is configured to drive the corresponding punching portions 310 to move radially to punch the side wall of the retainer 400 when the die is closed.

[0054] Through the above arrangement, the side punching die for the retainer can directly punch the retainer 400, compared with the traditional positive punching die, the riveting process is saved, and the strength of the bearing retainer 400 is avoided to be reduced in the subsequent riveting process.

[0055] Continuing to refer to Figure 2 In some embodiments, a plurality of through holes are radially arranged on the inner wall of the die cavity 300, and a sliding block 320 is slidably arranged in the through hole, wherein the punching portion 310 is arranged at one end of the sliding block 320 close to the center of the die cavity 300.

[0057] Specifically, when the die is closed, the driving block 110 moves downward to press the slope two 111 of the driving block 110 against the slope one 321 of the sliding block 320, so that the sliding block 320 moves towards the center of the die cavity 300.

[0058] Continuing to refer to Figure 2 In some embodiments, the die cavity 300 is further provided with a positioning column 330 corresponding to the inner diameter of the retainer 400, and the outer wall of the positioning column 330 is provided with a plurality of accommodation grooves 331 adapted to the punching portions 310.

[0059] Referring to Figure 3 In some embodiments, the punching portion 310 comprises a mounting block 311, a guide block 312 and a punch 313, the punch 313 and the guide block 312 are arranged at the upper end and the lower end of the mounting block 311 respectively, the mounting block 311 is arranged at one end of the sliding block 320 close to the center of the die cavity 300, and the outer wall of the positioning column 330 is further provided with a guide groove.

[0060] Specifically, the guide block 312 is slidingly arranged in the guide groove. When the mold is closed, the sliding block 320 moves towards the center of the mold cavity 300 to push the stamping part 310 to move towards the mold cavity 300, and when the guide block 312 slides into the guide groove, the punch 313 synchronously slides and extends into the accommodation groove 331, thereby realizing the hole on the side wall of the retainer 400.

[0061] Referring to Figure 2 In some embodiments, the length of the accommodation groove 331 is greater than the width of the retainer 400.

[0062] Specifically, after the punch 313 punches the hole, the waste material cut by the punch 313 on the retainer 400 can fall through the accommodation groove 331.

[0063] Referring to Figure 1 In some embodiments, a retainer side punching die is also provided, comprising: a lower die 200, the lower die 200 being provided with a mold cavity 300 for placing a retainer 400, and a plurality of stamping parts 310 adapted to move radially being arranged in the mold cavity 300; and an upper die 100, the upper die 100 being provided with driving parts for driving the corresponding stamping parts 310 to move radially; and a conveying part 500, the conveying part 500 being configured to convey a material strip 600 with the retainer 400 to the mold cavity 300; wherein when the mold is closed, the driving parts drive the stamping parts 310 to move radially to punch the side wall of the retainer 400.

[0064] Referring to Figure 4 In some embodiments, the two driving blocks 110 located in the moving direction of the material strip 600 are further provided with positioning blocks 120 corresponding to the inner wall of the retainer 400, and the two positioning blocks 120 are centrally symmetric about the center of the mold cavity 300; and the bottom of the positioning block 120 is provided with a rounded corner.

[0066] In summary, the mold cavity 300 of the lower die 200 of the present retainer side punching die is adapted to place the retainer 400, and the stamping parts 310 are arranged in the mold cavity 300. When the upper die 100 and the lower die 200 are closed, the upper die 100 drives the corresponding stamping parts 310 to move radially to punch the side wall of the retainer 400. Compared with the traditional positive punching die, the present retainer side punching die can directly punch the hole on the circular retainer 400, which saves the riveting process and avoids the reduction of the strength of the bearing retainer 400 in the subsequent riveting process.
