Description

Technical Field

[0001] The utility model relates to the technical field of automobile frame production equipment, and more specifically, it relates to a numerical control punching machine for a longitudinal beam. Background Art

[0002] The frame is the most important load-bearing component in the car, and the longitudinal beam of the frame is one of the key parts, so the longitudinal beam plays an important role in the load-bearing of the car. The side beam frame and the middle beam frame of the car all contain longitudinal beams. The longitudinal beam is usually stamped from low-alloy steel plates, and the stamped longitudinal beam needs to be punched.

[0003] The Chinese patent with publication number CN220196081U discloses a CNC punching machine for a longitudinal beam, and its technical highlights are: it includes a base and a punching table, and the punching table is installed on the top of the base; it also includes a moving device, a flipping device, a fixing device, a gantry, a support arm, a first cylinder and a punching head, the fixing device is installed on the punching table, the fixing device is used to fix the longitudinal beam, a moving device is arranged on the top of the base, the gantry is installed on the top of the base by moving left and right through the moving device, the support arm is installed on the gantry when it moves up and down, the fixed end of the first cylinder is installed on the top of the gantry, the moving end of the first cylinder is connected to the top of the support arm, the punching head is installed at the bottom of the support arm, the flipping device is arranged on the left and right parts of the base, and the flipping device is used to flip the longitudinal beam.

[0004] The above solution solves the problem of improving the convenience of punching processing on different sides of the longitudinal beam, reducing the labor intensity of manual operation and improving work efficiency. However, when punching the crossbeam, there is no support at the punching hole of the crossbeam. During the punching process, the crossbeam will bend around the punching hole, which makes the processing quality of the crossbeam not guaranteed after the processing is completed. At the same time, after the crossbeam is punched, it takes a long time to wait for the punching device to move to the next punching position, resulting in a long punching processing time.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
