Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of knife sharpening holders, and more particularly to a knife sharpening holder for shearing machine blades. Background Technology
[0002] Shearing machines, widely used in the metal processing industry, are primarily used for straight-line shearing of metal sheets. Their working efficiency and shearing quality are closely related to the sharpness of their blades. Over long-term use, shearing machine blades will wear down, leading to a decline in shearing performance. Therefore, they need to be periodically re-sharpened to restore the geometry and surface quality of their cutting edges.
[0003] Currently, when regrinding shearing machine blades, the blade needs to be fixed first, and then the blade is controlled to move back and forth on the whetstone for regrinding. However, the contact angle between the blade and the whetstone is usually fixed and cannot be flexibly adjusted according to the different wear levels of the blade. This fixed angle design easily leads to uneven regrinding of different parts of the blade edge, affecting the sharpness of the blade. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to provide a blade sharpening holder for a shearing machine, which can flexibly adjust the sharpening angle of the blade according to the degree of blade wear, thereby ensuring the uniformity of blade edge sharpening.
[0006] To achieve the above objectives, this utility model proposes a blade sharpening holder for a shearing machine, comprising a base, an electric slide rail, two clamping mechanisms, and two insertion mechanisms.

Rotating shafts are rotatably connected to both sides of the bracket, and a placement frame is connected between the two rotating shafts. An electric push rod is mounted on one side of the bracket, and a rack is connected to the piston end of the electric push rod. The rack meshes with a gear, which is mounted on the rotating shaft. The two clamping mechanisms are respectively mounted on the two sides of the placement frame. Two support plates are opposite each other on the top surface of the base, and a sharpening block is mounted on the front side of each support plate. The two insertion mechanisms are respectively mounted on the two support plates and are inserted into the sharpening blocks.
[0007] The blade sharpening holder for shearing machines of this invention can flexibly adjust the sharpening angle of the blade according to the degree of blade wear, thereby ensuring the uniformity of blade edge sharpening.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0020] The blade sharpening holder for a shearing machine according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0021] like Figures 1-3 As shown, the shearing machine blade sharpening holder of this utility model embodiment may include a base 10, an electric slide rail 20, two pressing mechanisms 40 and two insertion mechanisms 60. The electric slide rail 20 is mounted on the base 10 and is connected to a bracket 31. Both sides of the bracket 31 are rotatably connected to a rotating shaft 32. A placement frame 33 is connected between the two rotating shafts 32. An electric push rod 34 is mounted on one side of the bracket 31. A rack 35 is connected to the piston end of the electric push rod 34. The rack 35 meshes with a gear 36. The gear 36 is mounted on the rotating shaft 32. The two pressing mechanisms 40 are respectively mounted on the two sides of the placement frame 33.
[0022] The top surface of the base 10 has two support plates 50 facing each other. The front side of the two support plates 50 is provided with a sharpening block 51. Two plug-in mechanisms 60 are respectively provided on the two support plates 50 and are plugged into the sharpening block 51 respectively.
[0023] Specifically, the operator first activates the electric push rod 34, which moves the rack 35, thereby causing the gear 36 and the rotating shaft 32 to rotate at a certain angle, thus adjusting the angle of the placement frame 33 to achieve the re-sharpening of different cutting edge angles of the blade. Then, the blade is placed on the placement frame 33 and then pressed and fixed by two clamping mechanisms 40, so that the blade can abut against the sharpening block 51. Then, the electric slide rail 20 is activated, which drives the bracket 31 to move back and forth, so that the blade moves back and forth on the sharpening block 51 to perform the re-sharpening process.
[0024] When the sharpening block 51 gradually wears down, affecting the sharpening effect and requiring replacement, the operator operates the two insertion mechanisms 60 to release them from the insertion state of the sharpening block 51, and then inserts the new sharpening block 51 into the insertion mechanism 60.
[0025] The blade sharpening holder for shearing machines according to this utility model can flexibly adjust the sharpening angle of the blade according to the degree of blade wear, thereby ensuring the uniformity of blade edge sharpening.
[0026] In one embodiment of this utility model, such as Figure 1 As shown, the clamping mechanism 40 includes a fixed plate 41, an adjusting bolt 42, and a pressure plate 43. The fixed plate 41 is connected to the placement frame 33, the adjusting bolt 42 is threadedly connected to the fixed plate 41, and the bottom end of the adjusting bolt 42 is rotatably connected to the pressure plate 43.
[0027] It should be noted that by rotating the adjusting bolt 42, the staff can move the pressure plate 43, thereby pressing and fixing the blade placed on the placement rack 33 through the two pressure plates 43, and maintaining the stability of the blade.
[0028] In one embodiment of this utility model, such as Figure 3 As shown, the insertion mechanism 60 includes a housing 61, a spring 62, an insertion plate 63, and a pull rod 64. The housing 61 is mounted on the support plate 50. The spring 62 is connected to the inner wall of the housing 61. The insertion plate 63 is connected to the spring 62. The grinding block 51 has slots 511 on both sides. The insertion plate 63 passes through the housing 61 and is inserted into the slots 511. The pull rod 64 is connected to the insertion plate 63. The housing 61 has a through hole 611 through which the pull rod 64 passes.
[0029] It should be noted that when the sharpening block 51 needs to be replaced, the operator pulls the levers 64 on both sides to move the two insert plates 63 away from their respective slots 511, thereby removing the sharpening block 51. Then, the operator pulls the levers 64 on both sides again to move the insert plates 63, aligning the slots 511 on both sides of the new sharpening block 51 with the positions of the insert plates 63. Then, the levers 64 are released, and the spring 62 presses the insert plates 63, causing them to enter the slots 511 and fixing the position of the sharpening block 51.
[0030] In one embodiment of this utility model, such as Figure 2 As shown, a guide groove 37 is provided on one side of the bracket 31, and the rack 35 is slidably connected to the guide groove 37.
[0031] Understandably, both ends of the guide groove 37 are open. By setting the guide groove 37, the rack 35 can be guided and supported, making the rack 35 more stable when it moves.
[0032] In one embodiment of this utility model, such as Figure 1 As shown, the placement rack 33 is provided with an angle scale 70, which is located on the outside of the rotating shaft 32.
[0033] It should be noted that the angle dial 70 has a through hole in the center, which is larger than the size of the rotating shaft 32. The angle dial 70 is used to facilitate the comparison of the rotation angle of the blade.
[0034] In summary, the blade sharpening holder for the shearing machine according to this utility model embodiment can flexibly adjust the sharpening angle of the blade according to the degree of blade wear, thereby ensuring the uniformity of blade edge sharpening.
