DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0030] As Figure 1 and Figure 2 shown, a limiting structure includes: a base plate 20, a first side rod 21 fixedly connected to the top of the base plate 20. The top of the first side rod 21 is in a U-shape. A spring rod 22 is fixedly connected inside the opening of the first side rod 21. The spring rod 22 consists of two parts, the upper half with an open cavity at the bottom and the lower half elastically connected to the cavity of the upper half through a spring. A second side rod 23 is also fixedly connected to the top of the base plate 20. The top of the second side rod 23 is also in a U-shape. The first side rod 21 and the second side rod 23 are symmetrically arranged with their openings facing each other at the top of the base plate 20. Threaded holes are symmetrically opened on both sides of the top of the base plate 20. This is prior art, so it will not be elaborated here.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an adaptation structure can fix plates of different thicknesses to the top of the base plate 20. The adaptation structure includes: a lower seat 30, a lower roller 32, an upper plate 33, an upper roller 34, and a slider 35. The lower seat 30 is fixedly connected to the top of the base plate 20. The lower roller 32 is rotatably connected to the top of the lower seat 30. The upper plate 33 is slidably connected between the second side rod 23 and the first side rod 21. The upper roller 34 is rotatably connected to the side wall surface of the upper plate 33. The slider 35 is fixedly connected to the side wall surface of the upper plate 33. The upper roller 34 has the upper plate 33 and the slider 35 symmetrically arranged at both ends. The symmetric sliders 35 can slide in the openings of the second side rod 23 and the first side rod 21.

[0032] As Figure 1 , Figure 2 and Figure 3As shown, the top of the slider 35 in the opening of the first side rod 21 is fixedly connected to the bottom of the elastic rod 22, the cross-section of the lower seat 30 is a right-angled trapezoid, the lower roller 32 and the upper roller 34 are cylindrical, and a plurality of upper rollers 34 are evenly arranged between the symmetrical upper plates 33. The cross-section of the upper plate 33 is an inverted right-angled trapezoid. The front wall surfaces of the lower seat 30 and the upper plate 33 can form a V-shape with an opening facing forward. The adaptation structure also includes a roller groove 31, a sliding groove 36, a sliding block 37, a dial shaft 40, a clamping column 41 and a clamping groove 42. The roller groove 31 is opened at the top of the lower seat 30, the sliding groove 36 is opened on the front wall surface of the second side rod 23, and the sliding block 37 is fixedly connected to the second side rod 23. The front wall of the slider 35 in the opening, the dial shaft 40 is rotatably connected to the side wall of the sliding block 37, the clamping column 41 is fixedly connected to the top of the dial shaft 40, the clamping groove 42 is opened on the front wall of the second side rod 23, the wall of the lower seat 30 in the roller groove 31 is evenly rotatably connected with multiple lower rollers 32, the lower rollers 32 and the upper rollers 34 are parallel, the sliding block 37 is symmetrically arranged on the front wall of the slider 35, the dial shaft 40 is rotatably connected between the symmetrical sliding blocks 37, the sliding block 37 can slide vertically in the sliding groove 36, the clamping column 41 is cylindrical, and the clamping groove 42 is evenly and vertically opened on the front wall of the second side rod 23. The clamping groove 42 can adapt to the size of the clamping column 41

[0033] When in use, first, the clamping column 41 is separated from the clamping groove 42 by turning the dial shaft 40, and the position of the slider 35 is in an active state. Then, the plate to be processed can be inserted into the V-shaped groove of the roller groove 31 and the front wall of the upper plate 33. When the plate is placed between the upper plate 33 and the lower seat 30, the plate will push the upper roller 34 so that the upper plate 33 drives the slider 35 to slide vertically in the corresponding position. When the slider 35 slides, the spring in the cavity of the elastic rod 22 will be compressed to push the slider 35 downward. After the plate is placed, the clamping column 41 is pushed upward through the dial shaft 40 to the corresponding position of the clamping groove 42 to fix the position of the slider 35. At this time, the plate will be clamped by the upper roller 34 and the lower roller 32, and the clamped plate can be pushed backward to be processed. When processing each plate of different thickness, the position of the slider 35 is locked and unlocked by adjusting the clamping column 41 to adapt to the thickness of the plate.

[0034] In summary, by setting up an adapting structure, the thickness of the plate can be adapted more quickly and clamped, because the adapting structure clamps the plate through the upper and lower symmetrical lower rollers 32 and upper rollers 34, and the clamping column 41 is inserted into the clamping groove 42 to fix the distance between the lower roller 32 and the upper roller 34. When adjusting the clamping column 41, it is only necessary to move it. Therefore, compared with the prior art, this solution takes less time and is more convenient to fix the plate.

[0035] like Figure 4 and Figure 5As shown, the adapting structure also includes a cross bar 50, a locking groove 51, an adapting edge 52, an adapting groove 53, a handle 54 and an elastic groove 55. The cross bar 50 is fixedly connected between the symmetrical upper plates 33. The locking groove 51 is arranged at the top of the cross bar 50. The adapting edge 52 is slidably connected to the wall of the cross bar 50. The adapting groove 53 is arranged at the bottom of the adapting edge 52. The handle 54 is fixedly connected to the top of the adapting edge 52. The handle 54 cavity is hollow. The elastic groove 55 is symmetrically arranged in the handle 54 cavity. The adapting structure also includes a connecting plate 56, a return block 57, a grip 58, a lock column 60 and a fixed groove 61. The connecting plate 56 is slidably connected to the handle 54 cavity. The return block 57 is symmetrically fixed on the front and rear walls of the connecting plate 56. The handle 58 is fixedly connected to the top of the connecting plate 56, the locking column 60 is fixedly connected to the bottom of the connecting plate 56, the fixing groove 61 is penetrated and opened at the bottom of the handle 54 cavity, the cross bar 50 has a convex cross section, the adapting groove 53 can adapt to the size of the cross bar 50, the adapting edge 52 at the bottom of the adapting groove 53 is symmetrically fixedly connected with a rectangular plate, the top of the rectangular plate can contact the bottom of the cross bar 50, the top of the return block 57 is elastically connected in the elastic groove 55 by a spring, the fixing groove 61 can be penetrated and opened from the top of the adapting edge 52, and a plurality of locking grooves 51 are opened at the top of the cross bar 50, the fixing groove 61 can be connected with the locking groove 51, and the bottom of the locking column 60 can pass through the fixing groove 61 and enter the locking groove 51;

[0036] When the width of the plate needs to be adapted, the handle 58 is lifted upward from the handle 54 cavity, and the handle 58 can drive the connecting plate 56 to move upward, and the connecting plate 56 can drive the locking column 60 to move up and down from the fixed groove 61. When the return block 57 slides upward in the elastic groove 55, the spring at the top of the return block 57 is compressed, and the locking column 60 is separated from the locking groove 51 when it moves upward. At this time, the handle 54 is pushed toward the side of the plate to drive the adapting edge 52 to move toward and contact the side of the plate. After the adapting edge 52 contacts the side wall of the plate, the handle 58 can be stopped from being lifted, and the spring at the top of the return block 57 will push the return block 57 to the lowest point of the elastic groove 55, so that the connecting plate 56 drives the locking column 60 to move downward in the fixed groove 61 and the bottom of the locking column 60 enters the locking groove 51, thereby fixing the position of the adapting edge 52, and when the adapting edge 52 slides, it will slide along the top of the cross bar 50;

[0037] In summary, by providing an adjustable and fixed adaptor edge 52, plates of different widths can be adapted so that they can be better fixed between the lower roller 32 and the upper roller 34 to prevent plates with a width less than the symmetrical spacing between the second side rods 23 from being fixed between the lower roller 32 and the upper roller 34, resulting in processing failure, thereby further improving the scope of application of the device.

[0038] A hydraulic shearing device, including a body and a cutter, not shown in the figure, including all the above-mentioned limiting structures, the bottom of the base plate 20 is fixedly connected to the top of the body;

[0039] When in use, the threaded hole on the top of the base plate 20 is installed to the top of the machine body through bolts, and when the plate is clamped by the lower roller 32 and the upper roller 34, the plate can be sheared by pushing the plate in the direction of the cutter;

[0040] In summary, by setting a limiting structure, the hydraulic shearing device can process plates faster, thereby improving work efficiency, and can also enable the hydraulic shearing device to process plates of different sizes so that it has a wider range of applications.

[0041] Working principle: first, separate the clamping column 41 from the clamping groove 42 by flipping the dial shaft 40. At this time, the position of the slider 35 is in an active state. Then, the plate to be processed can be inserted into the V-shaped groove of the roller groove 31 and the front wall of the upper plate 33. When the plate is placed between the upper plate 33 and the lower seat 30, the plate will push the upper roller 34 so that the upper plate 33 drives the slider 35 to slide vertically in the corresponding position. When the slider 35 slides, the spring in the cavity of the elastic rod 22 will be compressed, thereby pushing the slider 35 downward. After the plate is placed, the clamping column 41 is pushed upward through the dial shaft 40 to the corresponding position of the clamping groove 42 to fix the position of the slider 35. At this time, the plate will be clamped by the upper roller 34 and the lower roller 32. The clamped plate can be processed by pushing it backward. When processing each plate of different thickness, the position of the slider 35 is locked and unlocked by adjusting the clamping column 41 to adapt to the thickness of the plate.
