Technical Field

[0001] The utility model relates to a metal sheet bending tool, in particular to a metal sheet bending jig. Background Art

[0002] In the packaging industry, bent metal sheets are often used to secure the boxes. These bends are often achieved using bending jigs. However, existing bending jigs generally lack the ability to adjust the bend depth (or length). Consequently, multiple different bending jigs are required to achieve different bend depths (or lengths), leading to high jig costs. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a metal sheet bending jig.

[0004] The purpose of the utility model is achieved through the following technical solutions: A metal sheet bending jig, comprising a front jig plate, a rear jig plate and a bending pressure plate, wherein the front jig plate and the rear jig plate are connected by screws and hexagonal nuts, and the bending pressure plate is connected to the upper end of the rear jig plate by a hinge, a depth adjustment gasket is clamped between the front jig plate and the rear jig plate, and adjustment push plates are respectively provided at both ends of the depth adjustment gasket, and the two adjustment push plates extend from the rear jig plate;

[0005] Turning the screw adjusts the distance between the front and rear jig plates. When the distance between the front and rear jig plates increases, the movement restriction on the depth adjustment pad is removed. Manually pushing the two adjustment push plates moves the depth adjustment pad up and down. Depending on the depth of the depth adjustment pad, the insertion depth of the metal sheet to be bent will also change, thereby enabling bends of varying depths (or lengths). The metal sheet to be bent is inserted between the distance formed between the front and rear jig plates, and the depth adjustment pad is used to support the metal sheet to be bent.

[0006] As an improvement to the metal sheet bending jig of the present invention, two symmetrical depth adjustment through holes are provided on the rear jig plate, and the two adjustment push plates extend from the depth adjustment through holes respectively. The two adjustment push plates can slide in the depth adjustment through holes. When the distance between the front jig plate and the rear jig plate becomes larger, the two adjustment push plates are manually pushed up and down to drive the position of the depth adjustment gasket.

[0007] As an improvement to the sheet metal bending jig of the present invention, grooves are provided on the upper edges of the corresponding surfaces of the front jig plate and the rear jig plate. A supporting metal sheet is fixedly mounted in the groove, with the upper edge of the supporting metal sheet protruding outside the groove. The supporting metal sheet is fixed in the groove by gluing.

[0008] As an improvement to the sheet metal bending jig of the present invention, a plurality of hexagonal screw holes are provided at intervals on the front jig plate, and the hexagonal nuts are installed in the hexagonal screw holes.

[0009] As an improvement to the sheet metal bending jig of the present invention, a plurality of screw holes are provided at intervals on the rear jig plate, the screws pass through the screw holes and are screwed to the hexagonal nuts, and the number of the screws is the same as the number of the hexagonal nuts.

[0010] As an improvement to the sheet metal bending jig of the present invention, the jig further includes a pressing metal sheet fixedly connected to the inner side of the bending platen and glued to the inner side of the bending platen. The pressing metal sheet can increase the rigidity of the contact between the bending platen and the sheet metal to be bent.

[0011] As an improvement to the sheet metal bending jig of the present invention, the hinge is connected to the bending pressure plate and the rear jig plate respectively by a plurality of fixing screws.

[0012] As an improvement to the sheet metal bending jig of the present invention, one end of the two adjusting push plates is vertically welded to the depth adjusting gasket.

[0013] The beneficial effects of the present invention are as follows: the present invention is used to bend metal sheets into right angles, has a simple structure and ingenious design, utilizes the depth adjustment gasket between the front jig plate and the rear jig plate to adjust the depth of insertion of the metal sheet, and can be adjusted according to the different bending depths of the metal sheet. One jig can adapt to products with multiple bending depths, which can greatly reduce the cost of the jig. BRIEF DESCRIPTION OF THE DRAWINGS
