In order to ensure that the container can complete loading and unloading work smoothly, a large amount of punching work will be performed during the container production process.

[0003] When processing a container, it is necessary to punch holes in the bottom plate of the container. Currently, the bottom plate of the container is punched using a punch through a double-row punching die.

[0004] For example, the prior art Chinese patent publication number "CN211330927U" provides a double-row punching die for the outer side panel of a container, including a bottom plate, a support seat is fixedly installed on the top wall of the bottom plate, a top plate is fixedly installed on the top of the bottom plate and the support seat, a hydraulic press is fixedly installed on the top wall of the top plate, a piston rod is fixedly installed on the output end of the hydraulic press, and the bottom end of the piston rod passes through the top plate and extends to the lower side of the top plate, a mounting plate is fixedly installed on the bottom end of the piston rod, a plurality of mounting blocks are movably installed on the bottom wall of the mounting plate, a movable block is movably installed on the bottom wall of each mounting block, and a punch is detachably installed on the bottom wall of each movable block.

[0005] The device can conveniently adjust the position of the mounting block longitudinally and the position of the movable block laterally, so the position of the punch can be conveniently adjusted, so that holes can be punched at appropriate positions of the outer side plate of the container according to processing needs. The design is reasonable and the practical effect is good.

[0006] In the existing double-row punching die, during the process of punching holes on the container bottom plate, the container bottom plate part is relatively large in size and is not convenient to be placed directly under the punch of the punching die. It is relatively difficult to move the container bottom plate. At the same time, during the process of punching holes on the container bottom plate, the punch is prone to squeeze and collide with the surface of the container bottom plate when punching holes downward excessively, thereby causing damage to the container. No buffering and anti-impact protection structure is provided to provide protection during the punching process of the container bottom plate. Utility Model Content

[0007] The utility model aims to solve the shortcomings of the prior art that the container bottom plate is large in size, inconvenient to be directly placed under the punch of the punching die, and difficult to move the container bottom plate, and proposes a double-row punching die.

[0030] In detail, guide holes 6 are opened at the four corners of the surface of the lifting plate 5, and the support column 2 slides through the guide holes 6, so that the hydraulic telescopic rod 9 can drive the lifting plate 5 and the punch 3 to move up and down stably; a mounting seat 10 is installed at the bottom end of the lifting plate 5, and a punch 3 is installed at the bottom end of the mounting seat 10. The punch 3 is vertically arranged and punches the bottom plate of the container.

[0031] A punching platform 15 is installed at the top of the base 1. The punching platform 15 is a rectangular plate structure and is horizontally arranged for placing the bottom plate of the container. The punching platform 15 is located below the punch 3. A first through hole 14 is opened on the surface of the punching platform 15. The first through hole 14 is located directly below the punch 3 and is used for the punch 3 to impact downward to avoid collision between the punch 3 and the punching platform 15.

[0032] Furthermore, a slide rail 13 is fixed to the top of the base 1. The slide rail 13 is a long strip structure and is horizontally arranged. Its length is equal to the length of the base 1, so that the punching table 15 can drive the container bottom plate to move to the bottom of the punch 3.

[0033] Moreover, a clamping strip 16 is fixed to the bottom end of the punching station 15 . The clamping strip 16 is a long strip structure, and its length is not greater than the length of the slide rail 13 . The clamping strip 16 is slidably mounted on the top end of the slide rail 13 .

[0034] Furthermore, the cross-section of the clamping strip 16 is a U-shaped structure, the top of the slide rail 13 is an arc-shaped protruding structure, and the top of the slide rail 13 is in sliding contact with the inner top of the clamping strip 16 .
