The clamping device used in the general market fixes the sheet metal plate in the clamping device by tightening screws when in use, and its clamping thickness is fixed. When sheet metal plates of different thicknesses need to be clamped, the sheet metal plate needs to be removed from the clamping device and then replaced with a different clamping device. This process is time-consuming and labor-intensive, reducing the efficiency of sheet metal processing. Utility Model Content

[0021] Example 1

[0022] See also Figure 1-Figure 3 As shown, this embodiment provides a sheet metal clamping device for a sheet metal bending machine, including a base 1. When in use, the base 1 is fixed on the sheet metal bending machine, and a main body 2 is fixedly installed on the top of the base 1. The clamping device can clamp sheet metal plates of different thicknesses through the main body 2. A sliding component 3 is sleeved on the main body 2. The clamped sheet metal plate is quickly taken out by loosening the sliding component 3. The main body 2 includes a slide bar 21. A wedge is arranged on the side wall of the slide bar 21. The wedge is gradually clamped when clamping the sheet metal plate through the convex and concave of the wedge on the slide bar 21. The slide bar 21 An upper clamp block 22 is fixedly installed on the side away from the base 1, and a lower clamp block 24 is arranged between the upper clamp block 22 and the base 1. When in use, the sheet metal plate is clamped between the upper clamp block 22 and the lower clamp block 24. The side wall of the lower clamp block 24 is fixedly connected with a sliding ring 23. The distance between the upper clamp block 22 and the lower clamp block 24 is changed by sliding the sliding ring 23 on the slide rod 21 to clamp sheet metal plates of different thicknesses. The sliding ring 23 is arranged in a C shape, and both ends of the C shape are sleeved on the slide rod 21, so that the lower clamp block 24 follows the sliding ring 23 to slide up and down on the slide rod 21.

[0023] The sliding assembly 3 includes a wrench 31, which is rotatably connected to the side wall of the sliding ring 23 through a latch, and the wrench 31 is set to a bent Y shape. The wrench 31 is squeezed by the Y shape to make the wrench 31 swing around the latch, and a limit block 33 is set between the Y-shaped openings. The limit block 33 is set in a square shape, and the edge of the square is stuck on the wedge of the sliding rod 21 to prevent the sliding assembly 3 from slipping. The limit block 33 is fixedly connected to a control rod 34, and the limit block 33 is rotatably connected to the wrench 31 through the control rod 34. When the wrench 31 is pressed down, the edge of the limit block 33 away from the control rod 34 is stuck in the wedge of the sliding rod 21, and the limit block 33 away from the control rod 34 is The spring 32 is provided on the side, and the spring 32 squeezes one end of the limit block 33 so that the limit block 33 is engaged with the wedge on the slide bar 21. When the wrench 31 is pressed down, the limit block 33 squeezes the wedge on the slide bar 21 downward, and the wrench 31 is released. Under the elastic force of the spring 32, the limit block 33 slides upward along the wedge, so that the lower clamping block 24 gradually approaches the upper clamping block 22 to clamp the sheet metal plate. The wrench 31 protrudes from one side of the control rod 34 and is fixedly connected to the control block. Pressing the control block down drives the limit block 33 to swing around the control rod 34, so that the side away from the control rod 34 is disengaged from the wedge, and then the lower clamping block 24 is away from the upper clamping block 22 to remove the clamped sheet metal plate.

[0024] When the sheet metal clamping device for a sheet metal bending machine of this embodiment is used, the sheet metal clamping device is fixed to the sheet metal bending machine through the base 1, and the sheet metal plate is placed between the upper clamping block 22 and the lower clamping block 24. By gradually squeezing the wrench 31, the limit block 33 is driven to gradually slide up on the wedge, so that the lower clamping block 24 gradually approaches the upper clamping block 22 and then clamps the sheet metal plate. When the sheet metal is completed, the control block on the downward pressure control rod 34 causes the limit block 33 to disengage from the wedge, thereby removing the sheet metal plate from between the upper clamping block 22 and the lower clamping block 24, so that the operator can easily and quickly remove the sheet metal parts, avoiding the problem of complicated removal, and improving work efficiency. At the same time, sheet metal plates of different thicknesses can be clamped, making this sheet metal clamping device for a sheet metal bending machine more practical.
