Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to a metal plate bending machine. Background Art

[0002] A sheet metal bending machine is an industrial equipment used to process sheet metal into a specific shape. It forms the desired shape by applying pressure to the sheet metal so that it bends along a predetermined bending line. Bending machines are widely used in the metal processing industry, including the manufacture of automotive parts, furniture, building structures, etc.

[0003] In the prior art, a metal sheet bending machine is generally used by a professional bender who holds the sheet and moves it to perform the bending operation.

[0004] However, when bending by holding the sheet metal, on the one hand, it is difficult to control the bending position, which affects the processing effect of the sheet metal; on the other hand, when bending by holding the sheet metal, the operator may accidentally touch mechanical parts such as tools, sliders, etc., causing fingers or arms to be clamped, resulting in production safety accidents. Utility Model Content

[0005] The utility model aims to provide a metal sheet bending machine to solve the above-mentioned technical problems of inaccurate bending position and production safety accidents caused by bending handheld sheets.

[0006] In order to solve the above technical problems, the utility model provides a metal sheet bending machine, which includes a workbench, an upper mold frame is arranged on the upper right surface of the workbench, an upper mold is arranged on the upper mold frame, a lower mold is arranged correspondingly below the upper mold, a positioning groove is arranged on the left side of the lower mold, a transverse slide rail is arranged in the middle of the positioning groove, an installation groove is arranged below the slide rail, a first screw device is arranged in the installation groove, a first slider is installed through the first screw device, an electric telescopic rod is arranged on the first slider, a second screw device is arranged at the rear end of the lower mold, the second screw device includes a push plate, and the push plate and the lower mold are matched.

[0007] Furthermore, an L-shaped support frame is arranged on the first sliding block, the right end of the support frame is connected to an electric telescopic rod, and the lower end of the electric telescopic rod is arranged with a soft gasket.

[0008] Furthermore, the second screw device also includes a second slider and a connecting rod; the second slider is installed on the second screw device, the upper end of the second slider is fixedly connected to the connecting rod, the front end of the connecting rod is fixedly connected to the push plate, and the push plate is engaged with the lower mold.

[0009] Furthermore, the front and rear sides of the positioning groove are provided with 45° chamfers.

[0010] Furthermore, hydraulic rods are provided on both sides of the lower end of the upper mold frame, and the upper mold is connected below the hydraulic rods.

[0011] Furthermore, a transition block is provided at the front end of the lower mold, a collection box is provided on the side of the workbench near the bottom of the transition block, an inner wall layer is provided inside the collection box, and the inner wall layer is made of sponge material.

[0012] The beneficial effects of the utility model are as follows: compared with the prior art, a metal sheet bending machine places the metal sheet to be processed into a positioning groove, then starts the electric telescopic rod to descend to fix the metal sheet, and then starts the first screw device, which pushes the metal sheet to be processed onto the lower mold through the slider, and the electric telescopic rod rises to cancel the fixation of the metal sheet. The first screw device drives the electric telescopic rod back to the initial position, which is convenient for the staff to load. The upper mold returns to the initial position after completing the bending of the metal sheet under the action of the hydraulic rod, and then starts the second screw device, and pushes the bent metal sheet on the lower mold into the collection box through the push plate connected to the second slider. The first screw device pushes the sheet to be bent to accurately control the bending position, ensure the processing effect of the sheet, and at the same time avoids the bending of the hand-held sheet, avoids the operator from accidentally touching the mechanical parts, avoids the fingers or arms from being clamped, and protects the operator's production safety.
