[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a scratch-proof and deformation-proof transverse shearing machine.

[0024] The utility model provides Figure 1-2 The scratch-proof and deformation-proof transverse shearing machine shown in the figure comprises a workbench 1, a fixing frame 2 is fixedly provided on the top of the workbench 1, a hydraulic cylinder 3 is fixedly installed on the top of the fixing frame 2, a top head 4 is fixedly provided at the end of the piston rod of the hydraulic cylinder 3, and the top head 4 adopts a hemispherical structure, which can increase the contact effect between the top head 4 and the extrusion surface; a transverse shearing blade 5 is provided above the workbench 1, and the transverse shearing blade 5 is inclined, and the downwardly inclined end of the transverse shearing blade 5 is elastically rotatably connected to the upper surface of the workbench 1, and the upwardly inclined end of the transverse shearing blade 5 is arranged corresponding to the position of the top head 4. A U-shaped seat 7 is fixedly provided on one side of the upper surface of the workbench 1, and a connecting rod 8 is fixedly provided on the downwardly inclined end of the transverse shear blade 5. One end of the connecting rod 8 extends to the interior of the U-shaped seat 7 and is rotatably connected through a rotating shaft 9. A torsion spring 10 is sleeved on the shaft wall of the rotating shaft 9, and the two ends of the torsion spring 10 are respectively fixedly connected to the U-shaped seat 7 and the connecting rod 8. One end of the transverse shear blade 5 can be rotated through the angle of the rotating shaft 9, so that the transverse shear blade 5 can be rotated and moved. The torsion spring 10 can apply an elastic torsional force to the transverse shear blade 5, so that the transverse shear blade 5 can be automatically lifted.

[0025] When the hydraulic cylinder 3 is extended, it drives the top head 4 to move downward, and through the top head 4, it contacts the transverse scissor blade 5, so that the transverse scissor blade 5 rotates downward and shears the material transversely. In this process, the transverse scissor blade 5 does not move downward in a vertical direction, but cuts downward in an inclined manner. After the transverse shearing is completed, the transverse scissor blade 5 is automatically lifted upward under the action of elastic force, and in the process of lifting, it is tilted so that the transverse scissor blade 5 is gradually separated from the material, which can effectively prevent the material from being scraped off.

[0026] like Figure 1-3As shown, pressure plates 6 are provided on both sides of the transverse shear blade 5, the height of the pressure plate 6 is less than the height of the blade of the transverse shear blade 5, and the pressure plate 6 is elastically and telescopically connected to the transverse shear blade 5, a sliding rod 11 is fixedly provided on the upper surface of the pressure plate 6, a sliding sleeve 12 is fixedly provided on the side wall of the transverse shear blade 5, the rod wall of the sliding rod 11 is slidably set inside the sliding sleeve 12, a fixing block 13 is fixedly provided on the upper end of the sliding rod 11, and a spring 14 is sleeved on the upper end of the sliding rod 11, and the two ends of the spring 14 are respectively fixedly connected to the sliding sleeve 12 and the fixing block 13, each pressure plate 6 is provided with two sliding rods 11, and two sliding sleeves 12 are provided on both sides of the transverse shear blade 5, the sliding rod 11 can move up and down inside the sliding sleeve 12, so that the fixed block 13 can stretch the spring 14, thereby making the pressure plate 6 have the function of elastic expansion and contraction.

[0027] When the transverse shear blade 5 rotates and moves downward, the pressing plate 6 presses the two sides of the transverse shearing part of the material, thereby preventing the material from being deformed during the transverse shearing process and improving the accuracy of the transverse shearing.

[0028] Finally, if Figure 1 As shown, a wear-resistant plate 15 is fixedly provided at one inclined end of the transverse shear blade 5 and at a position corresponding to the position of the plug 4 , and the plug 4 can contact the wear-resistant plate 15 in order to reduce the contact wear of the transverse shear blade 5 .

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
