Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, and particularly relates to a metal sheet shearing machine. Background Technique

[0002] A metal sheet shearing machine is a mechanical device used for cutting and trimming metal sheets. It usually consists of a base, supports, a transmission device, a cutting device, etc.

[0003] Patent No. CN218365181U discloses a shearing machine. The staff places the raw material plate on the top of the workbench. The staff cooperates with the baffle mechanism to fix the raw material plate on the top of the workbench. Two hydraulic cylinders are started, and the two hydraulic cylinders control the lifting plate to move downward. The automatic top-fixing mechanism fixes the top of the raw material plate. The lifting plate drives the upper cutting knife to cut the fixed raw material plate, improving the shearing efficiency, simplifying the operation process of fixing the raw material plate, improving convenience. The automatic top-fixing mechanism prevents the raw material plate from moving up and down during cutting, strengthening the fixation of the raw material plate, and contributing to the smooth completion of the cutting work. The function of the two support rods is to prevent the lifting plate from shaking left and right, improving stability; it includes a workbench, support rods, a top plate, hydraulic cylinders, a lifting plate, an upper cutting knife, a baffle mechanism and a support mechanism. The workbench is placed horizontally, and two strip-shaped grooves are provided on the top of the workbench.

[0004] The previous shearing machines have the following disadvantages: 1. The cutting tool does not have a limit guiding structure when moving, is prone to shaking during movement, and has a poor stability effect during sheet metal shearing. For this reason, we propose a metal sheet shearing machine. Summary of the Invention

Embodiment

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] As Figures 1 - 3 shown, a metal sheet shearing machine includes a vertical column 1, a bottom plate 4, a top beam 22, a servo electric cylinder 23, a rotating arm 19, a rotating shearing blade 20, a cross column 12 and a fixed shearing blade 13. Among them, a first cross beam 2 is welded between two groups of the vertical columns 1. A fixing bracket 17 is arranged near the center at the top of the first cross beam 2. The rotating arm 19 is connected in the fixing bracket 17 through a hinge bolt. A rotating shearing blade 20 is fixed on one side of the rotating arm 19 through a bolt. A second strip plate 26 is welded on the other side of the rotating arm 19. A U-shaped block 27 is welded on one side of the second strip plate 26. One side of the end of the vertical column 1 is fixed with a mounting arm 28 through a bolt. One side of the end of the mounting arm 28 is fixed with a bushing 29 through a positioning bolt. One end of the bushing 29 is provided with a guide wheel 31 through a rotating shaft. One side of one end of the mounting arm 28 near the bushing 29 is welded with an L-shaped fixing plate 30. One side of the L-shaped fixing plate 30 is tightly connected with the bushing 29 through a fastening bolt. A baffle plate 25 is welded near the back of the vertical column 1.

[0020] Among them, a backing plate 32 is welded on one side of the top of the cross column 12. A cross plate 14 is connected to one side of the top of the backing plate 32. A first strip plate 15 is welded on one side of the top of the cross plate 14. A fixed shearing blade 13 is locked and fixed on one side of the first strip plate 15 through a screw.

[0021] Among them, a reinforcing rib plate 16 is welded at the connecting corner of the cross plate 14 and the first strip plate 15.

[0022] Among them, a top beam 22 is welded near the top of the column 1. One end of the bottom of the top beam 22 is welded with a fixing plate 18.
