Description

Technical Field

[0001] The utility model relates to the technical field of welding piece processing, in particular to an anti-blocking punching die for welding piece processing. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Welded parts refer to workpieces manufactured using welding technology. In the process of processing welded parts, punching operations must be performed on the welded parts to meet the assembly requirements of the welded parts.

[0003] The patent with the patent authorization announcement number CN218798559U discloses a punching die, including a support plate, a telescopic cylinder is fixedly connected to the center of the top of the support plate, a punching block is fixedly connected to the center of the bottom of the punching plate, and a punching frame is fixedly connected to the bottom of the telescopic spring. Although the above patent can effectively avoid the deviation of punching accuracy by setting a punching frame to fix the material, it still has shortcomings in actual use. For example, when punching the material, the waste material and debris punched out fall into the punching groove, so the debris will remain on the inner wall of the punching groove, and the punching block will be completely embedded in the punching groove and contact with its inner wall when punching the material. The debris on the inner wall of the punching groove will gradually wear the surface of the punching block, causing the punching block to destroy the flatness of the inner wall of the punching surface of the material when continuing to punch the material, thereby reducing the punching quality of the workpiece.

[0004] Therefore, there is a particular need for an anti-blocking punching die for welding parts processing to solve the problems existing in the prior art. Utility Model Content

[0005] In order to overcome the disadvantage that when punching materials in the existing patents, the debris on the inner wall of the punching groove will gradually wear the surface of the punching block, resulting in the destruction of the flatness of the inner wall of the punching surface of the material when the punching block continues to punch the material, thereby reducing the punching quality of the workpiece, the utility model provides an anti-blocking punching die for processing welded parts.

The gear is meshed with the gear ring through the operation of the double-axis motor, the gear ring drives the two cleaning rods to rotate, the front cleaning rod drives the connecting rod to rotate, and the rotation of the threaded ring causes the bidirectional threaded rod to drive the cleaning block to move downward and upward.

[0007] Preferably, the center points of the two punching slots are vertically aligned, and the diameter of the punching slot on the lower side is greater than the diameter of the punching slot on the upper side.

[0008] Preferably, a screening frame is also included. The screening frame is placed at the lower part of the base. The screen aperture of the screening frame is relatively dense, and the screening frame is located below the punching slot, so that the screening frame can screen the waste and debris falling from the inside of the punching slot, and the lower end of the bidirectional threaded rod passes through the screening frame.

[0009] Preferably, a receiving frame is also included, and a receiving frame for catching debris is placed inside the screening frame.

[0010] Preferably, a collecting frame is also included, and the lower part of the base is connected to the collecting frame, and the collecting frame surrounds the screening frame so that large pieces of waste on the screen fall into the collecting frame.

[0011] Preferably, a guide rod is further included, the lower end of the bidirectional threaded rod is fixedly connected to the guide rod, and the guide rod is in contact with the inner wall of the screening frame.

[0012] Preferably, it also includes an oblique block, a lifting frame, a spring and a connecting plate.

[0014] 2. By setting up a screening frame, waste materials and debris fall from two punching slots onto the screening frame, and the screening frame screens the waste materials and debris to facilitate subsequent separate recycling of waste materials.

[0015] 3. By setting the oblique block, lifting frame, spring and connecting plate, the output shaft on the lower side of the dual-axis motor drives the oblique block to rotate and disengage from the connecting plate. At this time, the spring assists the lifting frame to drive the screening frame to move upward, and the oblique block continues to rotate to squeeze the connecting plate downward, so that it drives the screening frame to move downward, thereby making the screening frame move up and down, speeding up the screening speed of waste and debris.
