[0002] Cold-rolled steel strip is made of hot-rolled coil and is rolled at room temperature below the recrystallization temperature. It includes plates and coils. Cold-rolled steel has good performance. That is, through cold rolling, thinner and higher-precision cold-rolled strip and steel plate can be obtained. It has high flatness and high surface finish. The surface of cold-rolled plate is clean and bright, easy to be coated and plated, with many varieties and wide applications. It also has the characteristics of high stamping performance, no aging and low yield point.

[0003] For example, the Chinese patent publication number CN216150673U discloses a cold-rolled strip shearing device, comprising a workbench, a roller seat fixedly installed on one side above the workbench body, a transmission roller arranged horizontally in the middle position inside the roller seat body, a correction bin arranged on one side outside the roller seat, and the bottom of the bin body of the correction bin fixedly connected to the workbench. The utility model is provided with a collecting box, and the cold-rolled strip after shearing will move and fall into the interior of the collecting box under the drive of the conveyor belt. The setting of the collecting box plays a temporary role in collecting the cold-rolled strip, and when the cold-rolled strip after shearing is stacked, the two push plates arranged inside the collecting box will move and cooperate with the baffle inside the box to align the pile of cold-rolled strips, which facilitates the subsequent classification and collection of the cold-rolled strips and optimizes the working performance of the device.

[0004] The existing technology has the following problems:

The scraps cannot be used directly, and directly discarding them will cause a messy processing environment and make subsequent cleaning difficult. It may also cause cutting accidents and waste materials. The scraps are coiled together with the normally sheared cold-rolled steel coils and need to be removed later, resulting in labor waste.

[0029] By providing the scrap collecting structure 6, the scrap produced by shearing can be collected separately, which not only avoids collecting it together with the normally sheared steel coils, but also facilitates the recycling of the scrap.

[0030] like Figure 4 and Figure 5As shown, the edge material collection structure 6 includes two support plates 61, the bottoms of the two support plates 61 are respectively fixedly connected to the front and rear end positions on the right side of the top of the base 1, and the opposite sides of the two support plates 61 are rotatably connected to the first limit plate 63.

[0033] By providing the clamping rod 613, one end of the edge material can be fixed on the surface of the sleeve 611, thereby ensuring the stability of the winding when the winding starts.

[0034] like Figure 4 and Figure 5 As shown, a positioning plate 64 is fixedly connected to the right side of the middle part of the top of the base 1, and a sleeve rod 65 is rotatably connected to the middle part of the positioning plate 64.

[0036] like Figure 4 and Figure 5 As shown, the front and rear sides of the positioning plate 64 are fixedly connected to the first springs 66 , and the ends of the two first springs 66 that are away from each other are fixedly connected to the second limiting plate 67 , and the inner wall of the second limiting plate 67 is plugged into the outer wall of the sleeve 611 .

[0037] By providing the second limiting plate 67 , in cooperation with the first limiting plate 63 , the edge material can be assisted in rolling up, so that the rolling is beautiful and neat, and is convenient for removal and storage.

[0038] like Figure 5As shown, the bottom of the opposite sides of the two support plates 61 are fixedly connected with a rectangular block 610, the middle of the top of the rectangular block 610 is slidably connected with a round rod 614, the top of the round rod 614 is fixedly connected with a bottom frame 616, the bottom of the bottom frame 616 is fixedly connected with a second spring 615, the bottom end of the second spring 615 is fixedly connected to the top of the rectangular block 610, and the second spring 615 is located on the outside of the round rod 614, and the opposite surfaces on the front and rear sides of the top of the bottom frame 616 are rotatably connected with a round roller 617, and the round roller 617 is located below the outer wall of the sleeve 611 near the side of the first limit plate 63.

[0039] By providing the round roller 617, the edge material can be limited, thereby preventing the edge material from loosening and rebounding after winding is completed.

[0040] like Figure 6 As shown, the limiting structure 7 includes a rectangular frame 71, which is located in the middle of the left side of the shearing assembly 3. The inner wall of the rectangular frame 71 is rotatably connected to a threaded rod 72. The threads of the threaded rod 72 are symmetrically distributed in opposite directions. The front end of the threaded rod 72 extends from the front of the rectangular frame 71. The front and rear outer surfaces of the threaded rod 72 are threadedly connected to a limiting block 73. The bottom of the limiting block 73 is slidably connected to the inner wall of the rectangular frame 71. The left side and the inside of the limiting block 73 are rotatably connected to a number of cylinders 74.

[0041] By setting the limit block 73, the loaded steel coil can be limited, thereby assisting in its stable delivery into the shearing assembly 3.

[0042] like Figure 6 and Figure 7 As shown, the front and rear positions on the right side of the rectangular frame 71 are fixedly connected with a clamping block 75, and the side of the two clamping blocks 75 away from each other is plugged with a buckle 76, and the front and rear positions on the left side of the shearing component 3 are provided with a fixing groove 77, and the inner wall of the fixing groove 77 is plugged with the outer surface of the clamping block 75, and a circular hole 78 is provided in the middle right position of the front and rear surfaces of the shearing component 3, and the inner wall of the circular hole 78 is plugged with the outer surface of the buckle 76.

[0043] By providing the clamping block 75 and the fixing groove 77 , the limiting structure 7 can be disassembled and assembled, thereby facilitating its maintenance and replacement.

[0044] The working principle of the present invention is as follows: when in use, the cold-rolled steel strip is first placed on the loading rack 2, and then one end of the steel coil is delivered to the shearing assembly 3. Under the cooperation of the upper shear roller and the lower shear roller, the cold-rolled steel strip is sheared. The sheared steel coil passes through the guide rail groove 42 and the guide rail plate 41, and is finally reeled by the receiving roller in the receiving assembly 5. During the shearing process, one end of the edge material produced is delivered to the surface of the sleeve 611, and then fixed by the clamping rod 613, driving the driving motor 62, driving the first limit plate 63 close to the side of the driving motor 62 to rotate, and then driving the sleeve 611 to rotate. At this time, under the action of the clamping block 69 and the sleeve rod 65, the first limit plate 63 away from the driving motor 62 rotates synchronously, and then The edge material is wound up. At the same time, under the action of the second spring 615, the round roller 617 is always in contact with the sleeve 611 to limit the wound edge material. When the edge material needs to be taken out, the first spring 66 is pushed to the side close to the positioning plate 64, and then the electric telescopic rod 68 is retracted. At this time, the edge material can be withdrawn from the position of the sleeve 611 close to the side of the sleeve rod 65. During the cold-rolled strip loading process, the threaded rod 72 is first rotated according to the width of the cold-rolled strip, and the distance between the two limit blocks 73 is adjusted. Then the steel coil is passed through the middle of the limit block 73. The cylinder 74 reduces the friction between the limit block 73 and the steel coil, and at the same time reduces energy consumption. When the limiting structure 7 needs to be disassembled and replaced, the buckle 76 is removed and the block 75 is pulled out.
