Description

TECHNICAL FIELD

[0001] The utility model relates to the field of numerical control bus punching and shearing machine for copper bar processing, more specifically, to a numerical control bus punching and shearing machine for copper bar processing. BACKGROUND

[0002] The numerical control bus punching and shearing machine has the functions of punching, embossing and shearing on copper bars. In the process of clamping and dragging the processed copper bar, the clamping force of the clamping part on the copper bar is not easy to control accurately. In addition, the anti-slip tooth groove design of the clamping part, and the strong plasticity and easy variability of the copper bar, ultimately make it easy for the copper bar to have clamping marks during clamping by the clamping part, or even cause the copper bar to be deformed due to the clamping force of the clamping part, thereby affecting the processing quality of the copper bar. Moreover, during the clamping process, if the clamping force is too large, the end of the copper bar that has been deformed during clamping may be raised or even ejected, which makes it difficult for the numerical control bus punching and shearing machine to accurately punch and shear the raised copper bar, ultimately affecting the stable operation of the numerical control bus punching and shearing machine and the processing quality of the copper bar.

[0003] In the prior art, as disclosed in the utility model with the authorization announcement number CN218532464U, the utility model relates to the technical field of numerical control bus punching and shearing machines, and discloses a numerical control bus punching and shearing machine for copper bar processing, which comprises a numerical control bus punching and shearing machine body and a copper bar body. The rear end of the numerical control bus punching and shearing machine body is provided with a discharging conveyor belt. The discharging conveyor belt is provided with a clamping mechanism that can move forward and backward. The clamping mechanism comprises a clamping seat. The front end of the clamping seat is provided with two clamping heads that cooperate with each other. The two clamping heads are respectively provided with clamps. The side of the two clamps that faces each other is evenly provided with corresponding feed grooves in the vertical direction. Each feed groove is slidably connected with a clamping plate for clamping the copper bar body. The end of each two corresponding clamping plates that faces away from each other is provided with an elastic top piece for elastically supporting the clamping plate. This effectively improves the clamping protection effect and clamping stability of the copper bar body, ensures the stable operation of the numerical control bus punching and shearing machine body during punching and shearing processing operation, and improves the punching and shearing processing quality of the copper bar body.

[0004] In the above-mentioned patent, a movable clamping mechanism is provided. When the copper bar is continuously moved and punched, the feeding is unstable. When the copper bar is long and the feeding is from the outside to the inside, it is easy to deviate. It is not convenient to correct the copper bar of different widths and to align the feeding. The use is not flexible. SUMMARY
