Description

Technical Field

[0001] The utility model relates to the technical field of strip steel production auxiliary equipment, in particular to a cross-cutting shear device convenient for replacing shear blades. Background Technique

[0002] The cross-cutting shear is one of the key equipment in the continuous operation line of strip steel production. The shearing quality has a profound impact on the operation stability and reliability of the entire production line. The shear blade is a vulnerable part, and the replacement cycle is relatively frequent, usually ranging from 2 to 4 months.

[0003] At present, for the existing shear blade replacement device, generally two tracks are laid on the operation side of the cross-cutting shear. The tracks are strictly perpendicular to the direction of the knife seat of the cross-cutting shear. The height of the shear blade replacement slide is adjusted by turning the handle, adjusted to the same height as the upper shear blade or the lower shear blade, and then the hook head oil cylinder in the cross-cutting shear is released, the cross-cutting shear knife seat is loosened, the operator pulls the shear blade out to the shear blade replacement trolley, and then the shear blade is removed by a hoist or a crane, turned over or replaced with a new shear blade. Through on-site inspection, the operation time of a cross-cutting shear is 4 - 6 hours and requires 4 operators to cooperate to complete. It is not only time-consuming and laborious with low operation efficiency, but also very dangerous and easy to squeeze people. Therefore, there is an urgent need for a cross-cutting shear device convenient for replacing shear blades to solve the above problems. Summary of the Utility Model

[0013] Further, a slider is fixedly connected to the top of the upper tool holder, and a slideway adapted to the slider is opened inside the lifting frame.

[0014] The beneficial effect of adopting the above further solution is that a slideway with the same size as the lifting frame is opened inside the fixing frame, so that the upper tool holder slides into the inside of the lifting frame.

[0015] Further, a second motor is fixedly connected to the side wall of the lifting frame. A second threaded rotating shaft is fixedly connected to the output shaft of the second motor.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In the embodiment, it is given by Figures 1-5 A cross-cutting shear device facilitating the replacement of cutting edges. The present utility model includes the main body 1 of the cross-cutting shear device and the conveyor roller group 2. A replacement component is arranged on the side wall of the main body 1 of the cross-cutting shear device. A hydraulic push rod 7 is fixedly connected to the top of the main body 1 of the cross-cutting shear device. A fixed frame 8 is fixedly connected to the conveying rod of the hydraulic push rod 7. An upper tool holder 9 is movably connected inside the fixed frame 8. An upper cutting edge 10 is fixedly connected inside the upper tool holder 9. A connecting piece 11 is fixedly connected to the conveying rod of the hydraulic push rod 7.

[0029] In this embodiment, during actual use, a connecting chute 12 is opened inside the fixed frame 8. The connecting piece 11 is slidably connected inside the connecting chute 12. The setting of the connecting chute 12 enables the hydraulic push rod 7 to push the upper tool holder 9 to move up and down through the connecting piece 11. At the same time, the upper tool holder 9 can be slid off, improving the convenience during disassembly.

[0030] Specifically, referring to Figure 5 , the replacement components include a support frame 3 fixedly connected to the side wall of the main body 1 of the cross-cutting shearing device. A first motor 4 is fixedly connected to the top of the support frame 3. A first threaded rotating shaft 5 is fixedly connected to the output shaft of the first motor 4. A lifting frame 6 is threadedly connected to the outside of the first threaded rotating shaft 5. A limiting slide bar 22 is fixedly connected to the bottom of the support frame 3. The lifting frame 6 is slidably connected to the outside of the limiting slide bar 22. The conveying roller group 2 is arranged inside the main body 1 of the cross-cutting shearing device. A lower knife seat is arranged inside the main body 1 of the cross-cutting shearing device, and the lower knife seat is provided with the same replacement device.

[0031] In this embodiment, during actual use, due to the arrangement of the limiting slide bar 22, the lifting frame 6 can be stably lifted and moved. By starting the first motor 4 to drive the first threaded rotating shaft 5 to rotate, the lifting frame 6 can be lifted and moved. By lowering the height of the lifting frame 6, it is convenient for the staff to replace the cutting edge.

[0032] It should be noted that a slider 13 is fixedly connected to the top of the upper knife seat 9. A slideway 14 adapted to the slider 13 is opened inside the lifting frame 6. A slideway with the same size as the lifting frame 6 is opened inside the fixed frame 8, so that the upper knife seat 9 can slide into the inside of the lifting frame 6.

[0033] Specifically, referring to Figure 4 , a second motor 15 is fixedly connected to the side wall of the lifting frame 6. A second threaded rotating shaft 16 is fixedly connected to the output shaft of the second motor 15. A slide plate 17 is threadedly connected to the outside of the second threaded rotating shaft 16. A chain rope 18 is fixedly connected to the outside of the slide plate 17. A hook 19 is fixedly connected to one end of the chain rope 18 away from the slide plate 17. A hanging ring 20 adapted to the hook 19 is fixedly connected to the outside of the upper knife seat 9.

[0034] In this embodiment, during actual use, the slide plate 17 is slidably connected to the inside of the lifting frame 6. First, the hook 19 is hung into the inside of the hanging ring 20. By starting the second motor 15, the slide plate 17 is moved, and the upper knife seat 9 is pulled by using the chain rope 18, so that the upper knife seat 9 is pulled into the inside of the lifting frame 6.

[0035] It should be noted that a threaded groove extending into the upper knife seat 9 is opened inside the fixed frame 8. A fastening bolt 21 is threadedly connected to the inside of the threaded groove, and the upper knife seat 9 is fixed by the fastening bolt 21.

[0036] Working principle:

[0037] When the blade needs to be replaced, first cancel the restricted state of the upper tool holder 9 by rotating the fastening bolt 21. Start the first motor 4 to drive the first threaded rotating shaft 5 to rotate, so that the lifting frame 6 moves up and down, making the slideway inside the fixed frame 8 level with the slideway of the lifting frame 6. Then, hang the hook 19 inside the hanging ring 20. Start the second motor 15 to move the slide plate 17, and use the chain rope 18 to pull the upper tool holder 9, so as to pull the upper tool holder 9 into the lifting frame 6. Finally, lower the height of the lifting frame 6 to facilitate the staff to replace the blade. The replacement method of the lower cutting blade is the same as the above method.
