Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for iron plates. Background Technology

[0002] In the field of tinplate can making and metal processing, sheet metal punching is one of the core processes.

The first motor 9 drives the first movable seat 6 to move left and right. The conveying table 1 is provided with a through movable groove 4, which is parallel to the first slide rail 5. The first movable seat 6 is provided with a first cylinder 11. The output end of the first cylinder 11 is fixedly provided with a lifting block 12.

[0033] Specifically, the first movable seat 6 is provided with first sliders 7 on both sides, and the first sliders 7 are slidably connected to the first slide rail 5. The bottom of the conveyor table 1 is provided with a first lead screw 8 through a bearing seat. The first lead screw 8 is arranged parallel to the first slide rail 5. The first movable seat 6 is provided with a first ball screw nut 10. The first lead screw 8 and the first ball screw nut 10 are connected by threads. The first motor 9 is connected to the first lead screw 8 for transmission, and the first motor 9 drives the first movable seat 6 to move.

[0034] Specifically, the second movable seat 15 is provided with side plates 16 on both the front and rear sides, and a second slider 17 is provided on the inner side of the side plate 16.

[0035] Specifically, a third lead screw 24 is provided below the second movable seat 15 via a bearing, and a third ball screw nut 25 is provided on the third slider 22. The third lead screw 24 and the third ball screw nut 25 are connected by threads. The third lead screw 24 is connected to the third motor 23 for transmission, and the third motor 23 drives the third slider 22 to move.

[0036] Specifically, both the conveyor table 1 and the punching table 2 are equipped with several support legs 29 at their bottoms.

[0037] When using this utility model, an automated punching device is installed above the punching table 2. A limiting structure is provided on one side of the conveyor table 1. A conveyor belt is installed on one side of the conveyor table 1, and the conveyor belt transports the iron plate to the conveyor table 1 and is positioned by the limiting structure. At this time, the lifting block 12 is located below the table surface of the conveyor table 1, and the push block 13 cooperates with the left side of the iron plate. The first motor 9 drives the push block 13 to move to the right. After the iron plate moves to the right side of the conveyor table 1, the first cylinder 11 drives the lifting block 12 to move upward, lifting one side of the iron plate so that it is slightly higher than the upper end surface of the fixed jaw 2831. The second motor 18 drives the fixed jaw 2831 to move below the iron plate, and the second cylinder 281 drives the movable jaw 284 to clamp the iron plate. The first cylinder 11 drives the lifting block 12 to retract. The first motor 9 drives the push block 13 to reset, and the second motor 18 drives the clamping mechanism 28 to push the iron plate onto the punching table 2. The automated punching device punches the iron plate. The second motor 18 and the third motor 23 drive the clamping mechanism 28 to move back and forth and left and right, so that the different positions of the iron plate correspond to the automated punching device to complete the punching action. The punched workpiece is removed using a magnetic material absorption device. An automatic push plate is set on one side of the punching table 2. After the entire iron plate is punched, the second cylinder 281 drives the clamping mechanism 28 to open. The punched waste is pushed off the punching table 2 by the automatic push plate. Under the drive of the second motor 18, the clamping mechanism 28 resets, and the push block 13 continues to push the new iron plate to the right side of the conveyor table 1. The clamping mechanism 28 clamps the iron plate and moves it onto the punching table 2 for punching.
