Description

Technical Field

[0001] The utility model relates to a clamping device, in particular to a sheet metal clamping device for a sheet metal bending machine, belonging to the technical field of sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates. The products processed by sheet metal processing are called sheet metal parts. Sheet metal products have the characteristics of light weight, high strength, conductivity, low cost, good mass production performance, etc., and have a wide range of uses. Sheet metal processing has been widely used in the fields of electronics, communications, automobile industry, medical equipment, etc. Sheet metal bending machine is a special mechanical equipment used in sheet metal processing. It is mainly used to bend metal plates (such as iron plates, aluminum plates, stainless steel plates, etc.) into a certain angle or shape to meet the production needs of various sheet metal parts;

[0026] In one embodiment, a rectangular groove 6 is provided on the upper surface of the base 1, and a threaded rod 7 is rotatably installed between the left side and the right side of the inner wall of the rectangular groove 6. A moving block 8 is fixedly installed on the lower surface of the second support seat 4. The moving block 8 is threadedly sleeved on the outer side of the threaded rod 7, and the right end of the threaded rod 7 extends to the right side of the base 1. A handle 12 is fixedly installed on the right end of the threaded rod 7. A threaded hole 9 is provided on the right side of the moving block 8, and the threaded hole 9 is threadedly connected to the threaded rod 7. When the handle 12 is rotated, the handle 12 drives the threaded rod 7 to rotate, and the threaded rod 7 is threadedly connected to the threaded hole 9, so that the threaded rod 7 rotates and drives the moving block 8 to move, and the moving block 8 drives the second support seat 4 to move, so that it is convenient to limit sheet metal parts of different widths.

[0027] In one embodiment, two limit blocks 301 are fixedly installed on the upper surfaces of the first support seat 2 and the second support seat 4, and a connecting rod 306 is fixedly connected to the side where the two limit blocks 301 are close to each other, and a rectangular plate 302 is movably sleeved on the outer side of the connecting rod 306, and a plurality of springs 303 are fixedly connected to the lower surface of the rectangular plate 302, and an upper clamping plate 305 is fixedly connected to the end of the spring 303 away from the rectangular plate 302, and two guide rods 304 are fixedly installed on the upper surface of the upper clamping plate 305, and the top ends of the two guide rods 304 extend to the top of the rectangular plate 302, and a limit plate is fixedly installed on the top end of the guide rod 304, and the rotating rectangular plate 302 drives the upper clamping plate 305 and the plurality of springs 303 to rotate, so that the lower surface of the upper clamping plate 305 contacts the upper surface of the sheet metal, thereby clamping the sheet metal.

[0028] In one embodiment, a circular hole 11 is opened on the front side of the rectangular plate 302 , and the inner wall of the circular hole 11 is in movable contact with the outer side of the connecting rod 306 , so that the rectangular plate 302 can rotate on the outer side of the connecting rod 306 through the opened circular hole 11 .
