Description

Technical Field

[0001] This utility model belongs to the field of metal plate punching, and specifically relates to a punching device for metal plates. Background Technology

[0002] A punching machine is a device for punching holes in materials such as steel and iron. Due to the large size of the metal plate, it is difficult to position it. During the punching process, the metal plate often shifts. When fixing the metal plate, excessive pressure can cause deformation of the metal plate, making it impossible to punch accurately. Therefore, there is an urgent need for a punching device for metal plates that can avoid deformation and punch accurately. Utility Model Content

[0003] To address the technical deficiencies in the background art, this utility model proposes a punching device for metal plates, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0004] A punching device for metal plates includes a frame, a punching platform at the upper end of the frame, a fixing plate at the upper end of the punching platform, a first cylinder at the upper end of the fixing plate, a punching plate at the output end of the first cylinder, a punching head at the lower end of the punching plate, a second cylinder at the lower end of the fixing plate, a first connecting plate at the output end of the second cylinder, a first limiting hole inside the first connecting plate, a first connecting rod inside the first limiting hole, a first pressing plate at one end of the first connecting rod, a first limiting block at the other end of the first connecting rod, and a first spring on the outer side of the first connecting rod, one end of the first spring abutting against the first connecting plate, and the other end of the first spring abutting against the first pressing plate.

[0005] As an improvement to the above solution, the upper end of the perforated plate is provided with a mounting ring that matches the output end of the first cylinder. The output end of the first cylinder is connected to the mounting ring with bolts. The upper end of the perforated plate is also provided with a balance bar, and the fixed plate is provided with a balance hole that matches the balance bar.

[0006] As an improvement to the above solution, the surface of the frame is provided with a conveyor belt, and the interior of the frame is provided with a load-bearing plate corresponding to the lower part of the conveyor belt.

[0007] As an improvement to the above solution, a rotary motor is provided on one side of the frame, a rotary rod is provided at the output end of the rotary motor, and a first positioning plate is provided on one side of the rotary rod.

[0008] As an improvement to the above solution, a connecting column is provided on one side inside the frame, and a positioning screw hole is provided in the connecting column. The connecting column is bolted to a second positioning plate.

[0009] As an improvement to the above solution, a third cylinder is provided on the side of the frame away from the second positioning plate. The output end of the third cylinder is provided with a second connecting plate. The second connecting plate is provided with a second limiting hole. A second connecting rod is provided in the second limiting hole. One end of the second connecting rod is provided with a second pressing plate. The other end of the second connecting rod is provided with a second limiting block. A second spring is provided on the outside of the second connecting rod. One end of the second spring abuts against the second connecting plate. The other end of the second spring abuts against the second pressing plate.

[0010] The beneficial effects of this utility model are as follows: Before operation, the punching plate is installed at the output end of the first cylinder. Because of the bolt connection, a customized punching plate can be replaced according to work requirements. At the same time, the position of the second positioning plate is adjusted using the positioning screw holes, which can adapt to punching metal plates of various sizes. During processing, the metal plate is first placed on the surface of the conveyor belt. The rotary motor is controlled to rotate the second positioning plate 90 degrees and stand it up, so that the metal plate stops below the punching table. At this time, the third cylinder is controlled to press the second pressing plate against one side of the metal plate, adjusting the angle of the metal plate to increase the punching accuracy. When the second pressing plate is pressing the metal plate, after adjusting the angle of the metal plate, the second cylinder is controlled to press the first pressing plate against the surface of the metal plate to fix it, preventing the metal plate from shifting during punching and further increasing the punching accuracy. The first spring and the second spring play a buffering role to prevent the metal plate from deforming during pressure. At the same time, multi-angle positioning can increase the punching accuracy. After the metal plate is fixed, the first cylinder is started to push the punching plate, so that the punching head punches the metal plate. Attached Figure Description
