[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] In this embodiment, by Figure 1-4 The present invention includes a base 1, with support rods 2 at each of the four corners of the upper end of the base 1, a top frame 3 at the upper end of the support rods 2, a first electro-hydraulic push rod 4 at the middle of the upper end of the top frame 3, a connecting plate 5 at the output end of the first electro-hydraulic push rod 4, a punch 6 at the lower end of the connecting plate 5, a die 7 at the middle of the upper end of the base 1 corresponding to the punch 6, a through hole 8 formed in the middle of the bottom end of the die 7, a second electro-hydraulic push rod 9 in the through hole 8, a sliding sleeve 10 at the connection between the base 1 and the second electro-hydraulic push rod 9, and support legs 11 at each of the four corners of the lower end of the base 1.

[0021] The lower end of the support rod 2 is connected to the base 1 by bolts, and the upper end of the support rod 2 is connected to the top frame 3 by bolts. The support rod 2 supports the top frame 3 by relying on the base 1. The middle part of the upper end of the top frame 3 is connected to the first electro-hydraulic push rod 4 by bolts. The output end of the first electro-hydraulic push rod 4 is slidably connected to the middle part of the top frame 3. The output end of the first electro-hydraulic push rod 4 is connected to the middle part of the upper end of the connecting plate 5 by bolts. When working, the first electro-hydraulic push rod 4 can drive the connecting plate 5 to rise and fall.

[0022] The four corners of the connecting plate 5 are connected to the four corners of the upper end of the punch 6 by bolts. The die 7 is connected to the upper middle part of the base 1 by a slot. The die 7 has a punching cavity 12 formed in the middle. The punch 6 can be raised and lowered synchronously with the connecting plate 5.

[0023] The through hole 8 is formed in the middle of the bottom end of the die 7. The second electro-hydraulic push rod 9 is connected to the lower end of the base 1 by bolts. The output end of the second electro-hydraulic push rod 9 is slidably connected to the inner wall of the sliding sleeve 10 and the inner wall of the through hole 8. The upper end of the output end of the second electro-hydraulic push rod 9 is flush with the inner bottom end of the die 7 under normal conditions. During operation, it can push the original plate of the guard plate punched out in the die 7 upwards. The sliding sleeve 10 is connected to the middle of the lower end of the base 1 by a slot. The upper end of the support leg 11 is connected to the lower end of the base 1 by bolts.

[0024] Working principle: The device uses an external power supply and is controlled by an external control device. When using the device to punch the car body panel, the body panel material is placed on the upper end of the die 7. The first electro-hydraulic push rod 4 drives the connecting plate 5 and the punch 6 to move down. The punch 6 cooperates with the die 7 to punch the body panel material on the upper end of the die 7, so that the punched body panel is formed by relying on the punching cavity 12. The height of the first electro-hydraulic push rod 4 is limited by the support rod 2 and the top frame 3. Its maximum extension length at the output end, in conjunction with the punch 6, can ensure that the thickness of the punched body panel meets the requirements and that the material can be punched stably. After punching is completed, the first electro-hydraulic push rod 4 drives the connecting plate 5 and the punch 6 to rise. When the second electro-hydraulic push rod 9 is working, it can push the punched body panel out of the die 7, which can be collected manually or by a material handling robot.
