Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and particularly to a punching and processing device for a condenser manifold tube. Background Art

[0002] During the processing of the condenser manifold tube, according to the installation requirements, it is necessary to perform hole opening processing on the manifold tube. The invention patent with the patent authorization announcement number CN222371789U discloses a rapid punching device for a manifold tube, including a box body. A cover plate is fixedly connected to the top side of the box body. Two sliding grooves are opened on the top side of the cover plate. A sliding component is arranged inside the sliding grooves. An arc-shaped block one is fixedly connected to the top side of the sliding component. The right end of the arc-shaped block one is connected to an arc-shaped block two through a locking component one. A driving component is arranged on the outer wall of the right side of the box body. The bottom side of the sliding component is connected to the driving component through a gear set. A support frame is fixedly connected to the rear end of the top side of the cover plate. A bracket is arranged at the bottom end of the support frame. In this invention, the motor drives and the cooperation between the arc-shaped block one and the arc-shaped block two drive the manifold tube to move back and forth on the top of the cover plate, which is convenient for punching the manifold tube at different positions. At the same time, the drill bit can be conveniently replaced in view of the wear of the drill bit, saving a large amount of manpower and material resources.

[0003] However, this device has certain deficiencies. The wall of the manifold tube is relatively thin, and the punching process will cause the wall to be extruded and deformed, affecting the later installation and use. At the same time, the device is not convenient for protectively clamping manifold tubes with different lengths, resulting in the end of the manifold tube being extruded and damaged. Summary of the Invention

[0031] The specific implementation process of the present invention is as follows: When in use, manually move the manifold to slide on the upper end of the support 2 to the outside of the support column 45.
