Description

Since the existing hydraulic shearing machines shear the plates by vertical downward pressure, it is easy to fail to cut the plates, and the plates are deformed during the extrusion process, affecting the shearing efficiency of the equipment; 2. The plates to be sheared are relatively thin, and this shearing method is easy to cause deformation at the sheared edge of the plate, affecting the flatness of the incision. Summary of the invention

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Example

[0025] A shearing machine, such as Figure 1-3 As shown, it includes a machine tool 1, a plate conveying assembly 2 mounted on the machine tool 1, and a shearing assembly 3 mounted on the machine tool 1 and cooperating with the plate conveying assembly 2. The machine tool 1 includes a machine tool body 11, and a workbench 12 for assembling the plate conveying assembly 2 and the shearing assembly 3. The plate conveying assembly 2 is mounted on the plate feeding side of the workbench 12, and the shearing assembly 3 is mounted on the plate outlet side of the workbench 12.

[0026] The workbench 12 is provided with a drive roller assembly hole 121 on the plate inlet side corresponding to the plate conveying assembly 2, a hydraulic cylinder mounting seat 122 welded on both sides above the workbench 12 and corresponding to the drive roller assembly hole 121, and an adjustment slot 123 welded on both sides of the workbench 12 and corresponding to the hydraulic cylinder mounting seat 122. A hinge seat 124 is fixedly installed at one end of the plate outlet side corresponding to the shearing plate assembly 3 of the workbench 12 by bolts, and a screw assembly hole 125 and a guide column assembly hole 126 are also provided on the workbench 12, which are higher than the hinge seat 124. Specifically, the hinge seat 124 is used to hinge the shearing knife 31, and the screw assembly hole 125 and the guide column assembly hole 126 are respectively equipped with the screw 32 and the guide column 34.

[0027] like Figure 4 As shown, combined with Figure 1-3 The plate conveying assembly 2 includes a driving roller 21, a driving pulley 22 assembled at one end of the driving roller 21, a plate feeding servo motor 23 fixed inside the machine tool body 11 and connected to the driving pulley 22 through a belt, a pressure plate roller 24 movably assembled on the workbench 12 and parallel to the driving roller 21, and a hydraulic cylinder 25 vertically mounted on the workbench 12, with the output end fixedly mounted on both ends of the pressure plate roller 24. Specifically, both ends of the driving roller 21 pass through the driving roller assembly hole 121 and are fixedly mounted by a fixed bearing seat. The driving roller 21 is driven by the plate feeding servo motor 23 to feed the plate, and both ends of the pressure plate roller 24 pass through the adjusting groove 123 and are fixed to the output end of the hydraulic cylinder 25. The hydraulic cylinder 25 is vertically fixedly mounted on the hydraulic cylinder mounting seat 122.

[0028] It should be further explained that, when shearing, the plate feeding servo motor 23 is paused, and the hydraulic cylinder 25 extends downward so that the drive roller 21 squeezes the plate body, which is beneficial for the shearing assembly 3 to run and perform shearing processing. When feeding, the plate feeding servo motor 23 is started, and the hydraulic cylinder 25 extends downward so that the drive roller 21 squeezes the plate body, which is beneficial for the plate body to smoothly pass through the workbench 12 and enter the working area of ​​the shearing assembly 3.

[0029] like Figure 5-7 As shown, combined with Figure 1-3 The shearing plate assembly 3 includes a shearing knife 31 hingedly mounted on the workbench 12 at one end, a screw rod 32 assembled on the workbench 12 through fixed bearing seats at both ends, a screw rod slide 33 assembled on the screw rod 32 and assembled with the shearing knife 31, guide columns 34 assembled on the workbench 12 through fixing nuts at both ends and cooperating with the screw rod 32 to improve the smooth sliding of the screw rod slide 33, and a screw motor 35 fixedly mounted on the workbench 12 for driving the screw rod 32 to rotate.

[0030] Specifically, by reasonably installing the shearing knife, the screw rod, the screw rod slide, the guide column and the screw rod motor on the workbench, the shearing machine can efficiently complete the shearing process of the plate.

[0031] In this embodiment, a hinge hole 311 is provided at one end of the shearing knife 31 , which can be assembled with a hinge seat 124 installed on the plate outlet side of the workbench 12 .

[0032] In the present embodiment, an oblique guide groove 312 for assembling a screw slide 33 is transversely opened in the middle portion of the shearing knife 31. Specifically, the screw 32 drives the screw slide 33 to slide back and forth in the oblique guide groove 312, so that the shearing knife 31 can be controlled to rotate downward to shear the plate, or the shearing knife 31 can be controlled to rotate upward and lift up, thereby accurately controlling the rotation of the shearing knife to achieve stable shearing of the plate, avoiding bending and deformation of the plate, and thus improving the flatness of the incision.

[0033] In this solution, a large gear 321 is mounted on one end of the lead screw 32 close to the lead screw motor 35 , and can mesh with a driving gear on the output end of the lead screw motor 35 .

[0034] In the present embodiment, the screw slide 33 includes a screw nut 331 assembled with the screw 32, a fixing column 332 welded and fixed to the screw nut 331, and two assembly clips 333 with one end fixed to the fixing column 332 and the other end mounted on the guide column 34; specifically, the fixing column 332 passes through the oblique guide groove 312 of the shear knife 31 and is fixed to the two assembly clips 333.

[0035] In this embodiment, an annular groove 3321 is provided at the end of the fixing column 332, and an annular protrusion 3331 is provided at one end of the assembly clip 333 and the fixing column 332. Specifically, when the two assembly clips 333 and the fixing column 332 are assembled, the annular protrusion 3331 can be embedded in the annular groove 3321, which can improve the structural stability of the screw slide 33.

[0036] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
