[0032] As shown in Figures 1-7 , the embodiment provides a shaft rod body part R angle chamfering device, which comprises a base 2 and a stamping die 3, the part is placed on the base 2, the stamping die 3 is provided with a stamping groove 301 at the bottom, and the inner wall edge of the stamping groove 301 is matched with the R angle 102.

[0033] The stamping die 3 is provided with a mounting hole 4, a push block 401 is slidably connected in the mounting hole 4, and a spring 402 is arranged above the push block 401; under the action of the spring 402, the push block 401 can extend into the stamping groove 301.

[0034] When chamfering the fixed plate 101, the part is placed on the base 2, and then the stamping die 3 moves downward, and the fixed plate 101 is stamped through the stamping groove 301, so that the upper end face is treated with the R angle 102, and the chamfering purpose is achieved.

[0035] In the process of the reverse R angle 102, the punch groove 301 punches the fixed plate 101, at this time, the push block 401 is retracted into the mounting hole 4 under the action of the fixed plate 101, and the compression spring 402 is compressed, when the reverse R angle 102 is finished, the punch die 3 moves upward and separates from the base 2, and under the action of the spring 402, the push block 401 pushes the fixed plate 101 downward, avoiding the fixed plate 101 from being stuck in the punch groove 301, and avoiding affecting the reverse R angle efficiency.

[0036] As Figure 5 And Figure 7 The push block 401 is designed as T-shaped, so that it can only slide in the mounting hole 4 and cannot be separated from the mounting hole 4 downward.
