DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Please refer to Figures 1 to 5 The present invention provides a technical solution: a steel plate processing and shearing device, comprising a machine body 1, a protection frame 11, a hydraulic cylinder 12 and a shearing knife 13, wherein the protection frame 11 is fixedly mounted on the upper surface of the machine body 1, the hydraulic cylinder 12 is fixedly mounted on the upper surface of the protection frame 11, the shearing knife 13 is fixedly mounted on the output shaft of the hydraulic cylinder 12, and a smoothing component is arranged on the protection frame 11, the smoothing component comprises a smoothing module and a supporting module, and the smoothing module and the supporting module cooperate with each other to improve the shearing effect; The smoothing module includes a cylinder 2, which is fixedly mounted on the upper surface of the protective frame 11. The number of cylinders 2 is five and they are evenly distributed. A fixing plate 21 is fixedly mounted on the output shaft of the cylinder 2. A support column 22 is fixedly mounted on the bottom of the fixing plate 21. A limit block 23 is fixedly mounted on the bottom of the support column 22. A limit spring 24 is sleeved on the outer peripheral side of the support column 22. A positioning sleeve 25 is movably mounted on the outer surface of the support column 22. A positioning block 26 is fixedly mounted on the bottom of the positioning sleeve 25. A fixing frame 27 is fixedly installed on both sides of the middle positioning sleeve 25, and a smoothing member 28 is rotatably connected to the inner side of the fixing frame 27 through a torsion spring, and the bottom of the smoothing member 28 is in an arc shape; A smoothing piece 28 is provided on one side of the two side positioning sleeves 25, and the direction of the smoothing piece 28 is away from the middle positioning sleeve 25, and the bottom of the smoothing piece 28 is below the bottom of the positioning block 26; The diameter of the limit block 23 is larger than the diameter of the support column 22. One end of the limit spring 24 is fixedly connected to the bottom of the fixed plate 21. The other end of the limit spring 24 is fixedly connected to the positioning sleeve 25. The positioning sleeve 25 has a travel groove inside, and the travel groove is adapted to the limit block 23. The support module includes a mounting groove 29, which is opened inside the body 1. An airbag 210 is arranged inside the mounting groove 29. An air injection pipe 211 is fixedly connected to the upper side of one side of the cylinder 2, and an air guide pipe 212 is fixedly connected to the lower side of one side of the cylinder 2. The end of the air guide pipe 212 away from the cylinder 2 is fixedly connected to the airbag 210. A through groove 213 is opened on the upper side of the mounting groove 29, and the through groove 213 is located directly below the two connected positioning blocks 26.

[0020] Specifically, when in use, the user first needs to place the steel plate on the upper surface of the machine body 1 and align the shear line with the shear knife 13. After the steel plate is aligned, the air supply device needs to supply air to the cylinder 2 through the air injection pipe 211, thereby starting the cylinder 2, so that the cylinder 2 drives the positioning block 26 to descend; Among them, the middle cylinder 2 needs to be lowered first. During the lowering process of the middle cylinder 2, the middle smoothing piece 28 will flip over after contacting the steel plate, thereby smoothing the protrusions that may exist in the middle of the steel plate. When the cylinder 2 continues to descend, the positioning block 26 will position the steel plate, and the positioning sleeve 25 will squeeze the limit spring 24, causing the limit spring 24 to deform, thereby providing a stroke for the continued descent of the cylinder 2 until the smoothing piece 28 completely smoothes the raised part of the steel plate. After the middle of the steel plate is smoothed, the cylinders 2 on both sides need to be started in turn, so as to gradually smooth the steel plate from the middle to both sides, ensuring the flatness of the steel plate surface, thereby improving the shearing effect; It should be noted that, during assembly, the height of the fixing frame 27 on the positioning sleeve 25 can be changed according to the thickness of the steel plate to be sheared. When a thinner steel plate needs to be sheared, such a steel plate is more likely to bulge, and the bulge is more deformed. In this case, the fixing frame 27 can be installed at a lower position of the positioning sleeve 25, thereby increasing the smoothing stroke. Furthermore, when the cylinder 2 descends, the gas inside it will be introduced into the airbag 210 by the air guide tube 212, causing the airbag 210 to collide. The airbag 210 can contact the steel plate through the through groove 213. The steel plate at this contact position is not positioned by the positioning block 26. The airbag 210 can support its own deformation or the part that is not completely smoothed, thereby increasing the stability of the steel plate during shearing and further improving the shearing effect.

[0021] Example 2: Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 A balancing assembly is provided on the body 1, and the balancing assembly includes a bearing slot 3, the bearing slot 3 is opened inside the body 1, and a containing frame 31 is fixedly installed on one side of the body 1; A driving frame 32 is fixedly installed on one side of the fixing plates 21 on both sides. The driving frame 32 penetrates the protection frame 11 and extends to the outside of the protection frame 11. A driving slot 33 adapted to the driving frame 32 is opened inside the protection frame 11. A rack 34 is fixedly installed on one end of the driving frame 32 away from the fixing plate 21. A gear 35 is meshed with one side of the rack 34. The gear 35 is movably installed on the surface of the body 1. A turning frame 36 is fixedly installed on the edge of one side of the gear 35, a bearing member 38 is fixedly installed on the inner side of the turning frame 36, and the bearing member 38 is located in the inner cavity of the bearing groove 3. A turning groove 37 adapted to the turning frame 36 is opened on the surface of the body 1; The shape of the turning groove 37 is arc-shaped and matches the turning path of the turning frame 36 . When the positioning block 26 descends to the maximum stroke, the bearing member 38 turns ninety degrees and there is a gap between it and the shearing knife 13 .

[0022] On the basis of Example 1, when the cylinder 2 descends, it will drive the fixed plate 21 to descend, and the fixed plate 21 can be used to drive the driving frame 32 to descend in the driving groove 33, so that the driving frame 32 drives the rack 34 to descend, and the rack 34 can be used to drive the gear 35 to rotate, so that the gear 35 drives the flip frame 36 to move in the flip groove 37, so that the bearing member 38 flips, and when the cylinder 2 is completed, the bearing member 38 will complete a 90-degree flip, so that it is under the steel plate at the part to be sheared, and the steel plate is supported, so that the steel plate is in a balanced state before shearing, which can further improve the shearing effect; Furthermore, during the resetting process of the supporting member 38, the sheared steel plate will be driven to gradually descend and finally slowly fall into the inner cavity of the supporting groove 3, so as to avoid the steel plate falling directly after being sheared and causing wear to the containing space. Moreover, when the supporting member 38 is flipped again, the sheared steel plate can be pushed toward the containing frame 31, which is convenient for users to take and organize.

[0023] Example 3: Please refer to Figure 3 and Figure 6 A grinding assembly is provided on the protection frame 11, and the grinding assembly includes a mounting plate 4. The number of the mounting plates 4 is two, and they are fixedly mounted on the top of the inner cavity of the protection frame 11. A guide column 41 is fixedly mounted on the inner side of the mounting plate 4; Resistance springs 42 are sleeved on both sides of the outer surface of the guide column 41, one end of the resistance spring 42 is fixedly connected to a first connecting piece 43, the first connecting piece 43 is movably installed on the outer surface of the guide column 41, a resistance arm 44 is movably installed on the surface of the first connecting piece 43, a second connecting piece 45 is movably installed on one end of the resistance arm 44 away from the first connecting piece 43, a whetstone 46 is fixedly installed on one end of the second connecting piece 45 away from the resistance arm 44, and the whetstone 46 is movably contacted with one side of the hydraulic cylinder 12.

[0024] On the basis of Example 2, when the steel plate is positioned and smoothed, it is necessary to start the hydraulic cylinder 12 to drive the shearing knife 13 to descend and perform the shearing operation. During the descending process of the shearing knife 13, it will contact the whetstone 46, and the whetstone 46 will drive the resistance arm 44, so that the first connecting member 43 squeezes the resistance spring 42. The elastic force provided by the resistance spring 42 can make the whetstone 46 always contact with the shearing knife 13, so as to avoid the whetstone 46 and the shearing knife 13 being unable to contact each other after being worn out; When the whetstone 46 and the shear knife 13 are in continuous contact, the shear knife 13 will be sharpened by the whetstone 46 as it reciprocates up and down, so that the cutting edge of the whetstone 46 always remains sharp, thereby improving its shearing effect. It should be noted that a detachable fixed connection method is required between the second connecting member 45 and the whetstone 46 to facilitate the user to replace the whetstone 46.

[0025] A steel plate processing and shearing method, using the steel plate processing and shearing equipment as described above, comprises the following steps: S1: First, the steel plate needs to be placed so that the shear line is directly below the shear knife 13, and then the cylinder 2 is started to drive the positioning block 26 and the smoothing member 28 to descend, thereby completing the positioning and smoothing of the steel plate; S2: When the cylinder 2 descends, the gas inside it will be introduced into the airbag 210 by the air guide pipe 212. When the steel plate is not completely flattened at the position where there is no positioning block 26, the inflated airbag 210 will support the protruding part of the steel plate through the through groove 213; S3: When the cylinder 2 descends, it drives the driving frame 32 to descend, thereby driving the rack 34, so that the rack 34 drives the bearing member 38 to flip, thereby supporting the end of the steel plate to be sheared.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
