DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-Figure 4 The cutting device for steel ring production shown in the figure comprises a workbench 1, an L-shaped support frame 2 is fixedly arranged on the top of the workbench 1, a telescopic cylinder 3 is fixedly arranged on the bottom of the L-shaped support frame 2, a mounting plate 4 is fixedly installed on the output end of the telescopic cylinder 3, a shearing knife 5 is fixedly arranged on the bottom of the mounting plate 4, a shearing hole matched with the shearing knife 5 is opened on the top of the workbench 1, a strip-shaped sliding hole is opened on the top of the workbench 1, an adjusting screw 6 is rotatably installed on the inner wall of the side of the strip-shaped sliding hole, a moving block 7 matched with the strip-shaped sliding hole is threadedly sleeved on the adjusting screw 6, a positioning plate 8 is fixedly installed on the top of the moving block 7, the end of the adjusting screw 6 extends to the outside of the workbench 1 and is fixedly installed with an L-shaped hand crank 9, A locking gear 10 is fixedly sleeved on the adjusting screw 6, a first protrusion 11 is fixedly installed on the side of the workbench 1, a hexagonal sliding hole is opened on the side of the first protrusion 11, a hexagonal sliding rod 12 is slidably installed in the hexagonal sliding hole, a locking tooth block 13 meshing with the locking gear 10 is fixedly installed on one end of the hexagonal sliding rod 12, a baffle located between the locking tooth block 13 and the first protrusion 11 is fixedly sleeved on the hexagonal sliding rod 12, and an elastic reset element for squeezing and pushing the baffle to automatically reset is provided on the first protrusion 11, and the elastic reset element includes a reset spring 14 sleeved on the hexagonal sliding rod 12, and both ends of the reset spring 14 are respectively fixedly installed on the first protrusion 11 and the side of the baffle.

[0024] By means of the above structure, when the hexagonal slide bar 12 is pulled, the locking tooth block 13 will be driven away from the locking gear 10, and the adjusting screw 6 will be loosened. At this time, the L-shaped hand crank 9 can be rotated. The rotation of the L-shaped hand crank 9 will drive the positioning plate 8 to move horizontally through the adjusting screw 6 and the moving block 7, so that the shearing size of the steel ring plate can be adjusted and positioned. After the adjustment is completed, the hexagonal slide bar 12 is released. Under the elastic force of the reset spring 14, the push-block will be squeezed and pushed to automatically reset, and then the locking tooth block 13 can be automatically reset and meshed with the locking gear 10 through the hexagonal slide bar 12, so that the adjusting screw 6 is automatically locked and cannot be rotated, and the locked state can be maintained all the time. Therefore, during use, the automatic displacement of the positioning plate 8 caused by the vibration of the device or the accidental contact with the L-shaped hand crank 9 can be effectively reduced, thereby ensuring the shearing accuracy of the steel ring plate size. The structure is simple, easy to use and practical.

[0025] As a preferred implementation of this embodiment, a control pull ring 15 is fixedly installed at the other end of the hexagonal slide bar 12, and a second protrusion 16 is fixedly installed on the side of the workbench 1. A latch slide hole is provided on the top of the second protrusion 16, and a fixed latch 17 adapted to the control pull ring 15 is slidably installed in the latch slide hole. The advantage of this arrangement is that when the hexagonal slide bar 12 is pulled to loosen the adjustment screw 6, the control pull ring 15 will be driven to move together. When the control pull ring 15 is moved to a position corresponding to the fixed latch 17, the fixed latch 17 can be inserted into the control pull ring 15 to fix the control pull ring 15 and the hexagonal slide bar 12, so that the adjustment screw 6 can be kept in a loosened state, and the staff no longer needs to pull the hexagonal slide bar 12 all the time, which is more convenient to use.

[0026] In this embodiment, the top of the fixed latch 17 and the top of the workbench 1 are fixedly mounted with a connecting rope 18. The advantage of this arrangement is that the connecting rope 18 can be used to connect the fixed latch 17, thereby preventing the fixed latch 17 from being accidentally dropped and lost during use.

[0027] As a preferred implementation manner of this embodiment, two fixed blocks 19 are fixedly installed on both sides of the mounting plate 4 away from each other, vertical sliding holes are opened on the tops of the four fixed blocks 19, vertical sliding rods 20 are slidably installed in the four vertical sliding holes, and a fixed pressure plate 21 is fixedly installed together at the bottom ends of the two vertical sliding rods 20 located on the same side, and an extrusion spring 22 is sleeved on the vertical sliding rod 20, and the two ends of the extrusion spring 22 are respectively fixedly installed on the top of the fixed pressure plate 21 and the bottom of the fixed block 19. The advantage of such a configuration is that when the telescopic cylinder 3 is started to make the mounting plate 4 and the shear knife 5 move downward to shear the steel ring plate, the fixed pressure plate 21 will be driven downward by the fixed block 19 and the extrusion spring 22. When it moves downward until the fixed pressure plate 21 contacts the top of the steel ring plate, the fixed pressure plate 21 continues to move downward, causing the extrusion spring 22 to undergo elastic deformation. At this time, under the elastic force of the extrusion spring 22, the fixed pressure plate 21 will be squeezed downward to press the steel ring plate tightly and fix it on the workbench 1, thereby preventing the steel ring plate from moving during shearing, further ensuring the shearing accuracy of the steel ring plate size, and improving practicality.

[0028] In this embodiment, anti-skid pads are fixedly arranged at the bottom of the two fixed pressing plates 21. The advantage of such arrangement is that the friction between the fixed pressing plates 21 and the steel ring plate can be increased by the arrangement of the anti-skid pads, and the clamping and fixing can be more stable.

[0029] As a preferred implementation of this embodiment, two limiting guide rods 23 are fixedly installed on the top of the mounting plate 4, and two limiting guide holes are opened on the top of the L-shaped support frame 2. The two limiting guide rods 23 are slidably installed in the two limiting guide holes. The advantage of this arrangement is that the mounting plate 4 can only move vertically up and down, which plays a role of limiting guidance and has good stability during shearing.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
