DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1-Figure 5 The present application provides a self-tightening end plate shearing device, including a shearing machine 10 and a tightening and limiting assembly 20.

[0029] Among them, the shearing machine 10 can shear the end plate, and the clamping and limiting component 20 can limit the top and both sides of the end plate to be sheared, and can limit end plates of various specifications, thereby improving the accuracy of shearing the end plate and preventing deviation.

[0030] See also Figure 1 and Figure 2 The shearing machine 10 includes a frame 110, a shearing piece 130 is installed on the top of the frame 110, a shearing platform 120 is provided on the frame 110 below the shearing piece 130, and a slide groove 121 is symmetrically provided on the shearing platform 120, and a plurality of threaded holes are equidistantly provided inside the slide groove 121; wherein, the end plate is placed on the shearing platform 120 and pushed under the shearing piece 130, and the shearing piece 130 is started to shear the end plate.

[0031] In this embodiment, the shearing member 130 includes a mounting rod 131, a cylinder 132, a mounting seat 133, and a shearing blade 134. The mounting rod 131 is fixedly connected at both ends to the top opposite surfaces of the frame 110. The barrel end of the cylinder 132 is mounted on the lower surface of the mounting rod 131. The mounting seat 133 is fixedly connected to the rod end of the cylinder 132. The shearing blade 134 is mounted on the mounting seat 133. When the cylinder 132 is activated, the shearing blade 134 descends, thereby shearing the end plate.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The clamping and limiting assembly 20 includes a sliding plate 210. The bottom of each of the two sliding plates 210 is fixedly connected to a first slider 211. The first slider 211 is slidably arranged inside the slide groove 121. A fastening bolt 280 is screwed into a threaded hole. The fastening bolt 280 is screwed to the bottom of the first slider 211. A limiting member 270 is provided on each of the two sliding plates 210. The front end of the shearing member 130 is connected to a top pressing member 230 and is located above the shearing platform 120. When the end plate needs to be sheared, the end plate is placed on the shearing platform 120, and then the sliding plates 210 on both sides are slid according to the width of the end plate so that the sliding plates 210 slide to the appropriate position. Then, the fastening bolt 280 is passed through a threaded hole and fixed to the bottom of the first slider 211 to achieve the fixation of the sliding plates 210. Then, the two limiting members 270 are rotated again so that the side of the end plate can be limited. The two position-limiting members 270 enable the end plate to be pre-positioned, preventing it from shifting during insertion. This prevents the end plate from shifting during shearing, improving the quality of the sheared end plate. Furthermore, the position-limiting members 270 can position end plates of varying specifications, particularly those with modest width variations. The sliding arrangement of the sliding plate 210 and the shearing platform 120 allows for positioning end plates with large width variations, improving the practicality of the entire shearing device. The fastening bolts 280 secure the sliding plate 210 after sliding, improving the stability of the position-limiting mechanism.

[0033] In this embodiment, the limiting member 270 includes a handwheel 271, a threaded rod 272, and a limiting plate 273. One end of the threaded rod 272 is fixedly connected to the handwheel 271, and the other end of the threaded rod 272 is threadedly connected to the sliding plate 210 and rotatably connected to the limiting plate 273. The limiting plate 273 limits the side of the end plate. When the end plate needs to be limited, the handwheel 271 is rotated, causing the threaded rod 272 to rotate, thereby moving the limiting plate 273 and limiting the side of the end plate.

[0034] Furthermore, mounting grooves are formed on the opposing surfaces of the two limiting plates 273. Several rollers 290 are rotatably mounted within the mounting grooves, and all rollers 290 are spaced apart. The arrangement of the rollers 290 reduces effort when pushing the end plate, facilitating insertion of the end plate.

[0035] Specifically, the bottom of the limiting plate 273 is fixedly connected to a second slider 240, and the second slider 240 is slidably arranged inside the sliding groove 121. Among them, the setting of the second slider 240 makes the limiting plate 273 more stable when moving.

[0036] In a specific configuration, a crossbeam 220 is slidably provided on the opposite surface of the frame 110 above the top pressing member 230. The top of the top pressing member 230 is connected to the bottom of the crossbeam 220. A fixed connector 250 is fixedly connected to the rear side of the top pressing member 230. The other end of the fixed connector 250 is fixedly connected to the shearing member 130. When the shearing blade 134 descends to shear the end plate, the top pressing member 230 also descends, pressing the upper surface of the end plate to improve the limiting effect. After a shearing operation is completed, the shearing blade 134 rises, and the top pressing member 230 also rises, leaving the upper surface of the end plate and not hindering the advancement of the end plate. By connecting the top pressing member 230 and the shearing member 130, the top pressing member 230 and the shearing member 130 can be raised and lowered simultaneously, achieving automatic compression of the end plate, realizing shearing and compression, without the need for workers to press, and reducing labor intensity.

[0037] Furthermore, the top pressing member 230 includes a pressing plate 231 and an elastic connecting portion 232, wherein both ends of the elastic connecting portion 232 are respectively connected to the cross beam 220 and the pressing plate 231. The elastic connecting portion 232 enables the pressing plate 231 to elastically press the end plate without causing damage to the end plate.

[0038] Specifically, a plurality of pressure columns 260 are equidistantly arranged on the lower surface of the pressure plate 231. The pressure columns 260 are used to press the upper surface of the end plate.

[0039] In a specific configuration, the fixed connector 250 includes a connecting rod 251 and a fixing block 252. The fixing block 252 is fixed to the pressure plate 231. The ends of the connecting rod 251 are fixedly connected to the fixing block 252 and the shearing member 130, respectively. The connection between the pressure plate 231 and the mounting seat 133 is achieved so that the pressure plate 231 can be raised and lowered simultaneously with the shearing blade 134.

[0040] When the end plate needs to be sheared, the end plate is placed on the shearing table 120. Then, the sliding plates 210 on both sides are slid according to the width of the end plate until the sliding plates 210 slide to the appropriate position. Then, the fastening bolt 280 is passed through a threaded hole and fixed to the bottom of the first slider 211 to fix the sliding plate 210. Then, the two limiting members 270 are rotated again to limit the side of the end plate. After limiting, the end plate is pushed forward so that the end plate is directly below the shearing member 130. Then, the shearing member 130 is activated to allow the shearing member 130 to shear. When the shearing member 130 descends to shear, the top pressing member 230 descends accordingly to press the end plate. By setting the two limiting members 270, the end plate to be sheared can be pre-limited to prevent the end plate from deflecting when pushed in, thereby preventing the end plate from deflecting during shearing, and improving the quality of the end plate shearing. Furthermore, the position limiter 270 can limit the position of end plates of varying sizes, particularly those with relatively small width variations. The sliding arrangement of the sliding plate 210 and the shearing platform 120 allows for the position limiter of end plates with large width variations, improving the practicality of the entire shearing device. The fastening bolts 280 secure the sliding plate 210 after sliding, improving the stability of the position limiter.

[0041] It should be noted that the specific model and specifications of the cylinder 132 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and principle of the cylinder 132 are clear to those skilled in the art and will not be described in detail here.
