[0002] In the production of fitness equipment, when processing materials such as pedals and seat plates, laser cutting is usually used. That is, the material to be cut is placed on the worktable of the laser cutting equipment, and several rows of serrated support members on the worktable support the material to be cut. Then, the material to be cut is laser cut to obtain a material of a specific shape.

[0003] However, the length of the pedal and seat plate is greater than the distance between adjacent serrated supports on the workbench. Therefore, after cutting, the pedal and seat plate cannot fall directly downwards, and the cut material is located inside the original material, making it inconvenient to remove the material. Utility Model Content

Several lifting frames span the worktable; each lifting frame slides in conjunction with the inner slide rail; each lifting frame is provided with a clamping component for clamping the edge of the plate, the clamping component slides in conjunction with the lifting frame in the height direction, and the height of the lifting is greater than the thickness of the plate; Wherein, the width of the clamping component is less than the distance between adjacent saw tooth support components; when the laser cutting component cuts the plate, several of the lifting frames are located at one end of the worktable; after the laser cutting component finishes cutting, several of the lifting frames are spaced apart in the plate area.

[0006] In one possible implementation, clamping assemblies are provided on both sides of each of the lifting frames, and each clamping assembly includes: The sleeve slides in conjunction with the lifting frame along the height direction; the sleeve has an opening on the side facing the plate. A sliding component is slidably engaged with the sleeve; one end of the sliding component can extend out of the sleeve, and the extended end of the sliding component has a slot for insertion into the plate, the top surface and bottom surface of the slot contacting the top surface and bottom surface of the plate, respectively.

[0007] In one possible implementation, the top surface of the slot has a groove, and an abutment plate is slidably disposed within the groove, the abutment plate being able to press against the plate material; The abutment plate has a rotatable clamping bolt on its top, and the other end of the clamping bolt protrudes from the sliding component. The sliding component has a threaded hole that engages with the clamping bolt. The distance between the abutment plate and the clamping bolt in the height direction is constant.

[0008] In one possible implementation, the inner wall of the sleeve has a guide groove, and the sliding component has a guide block that slides with the guide groove; The guide groove is fixedly provided with a baffle at the opening of the sleeve to limit the sliding position of the guide block.

[0009] In one possible implementation, the lifting frame has an adjustment groove, an adjustment screw is rotatably disposed in the adjustment groove, and an adjustment component that is threadedly engaged with the adjustment screw is slidably disposed in the adjustment groove. The adjustment component is connected to the sleeve to drive the sleeve to rise and fall.

[0010] In one possible implementation, the lifting frame has adjustment slots, adjustment components, and adjustment screws on both sides, and the two adjustment screws are connected by a chain drive structure. The chain drive structure is located on the top of the lifting frame, and the top of the lifting frame is provided with a housing to accommodate the chain drive structure; a servo motor is provided on the top of the housing at the position of one of the adjusting screws, and the output shaft of the servo motor is connected to the adjusting screw.

[0011] In one possible implementation, the lifting frame has a support groove at the position after the adjusting component slides, the support groove is horizontally arranged and is a through groove; a support plate is inserted into the support groove, and the support plate can contact the bottom of the adjusting component.

[0012] In one possible implementation, the support plate is connected to the lifting frame via a flexible rope.

[0013] In one possible implementation, a limiting plate is connected to the end of the inner slide rail, the limiting plate being able to contact the side of one of the lifting frames to limit the sliding position of the lifting frame.

[0014] In one possible implementation, in the initial position, the truss is located at one end of the workbench, and the lifting frame is located at the other end of the workbench; a waste board collection box is provided on the workbench at one end of the lifting frame.

[0015] When cutting sheet metal using a laser cutting assembly, several lifting frames are slid to one end of the worktable to avoid the truss and prevent interference with the laser cutting process. After cutting, the truss moves to the other end of the worktable, and several lifting frames are slid to the area where the sheet metal is located, with the lifting frames spaced apart. By sliding the clamping assembly downwards, the height of the clamping assembly matches that of the sheet metal, facilitating the clamping assembly to hold the edge of the sheet metal. By moving the clamping assembly upwards, the sheet metal is moved upwards, separating it from the worktable, with the distance between the sheet metal and the worktable greater than the thickness of the sheet metal. If the cut part on the sheet metal is not separated from the sheet metal, the operator can tap the cut area on the sheet metal with a tool to make the cut area fall onto the worktable. Then, by sliding the lifting frames on the worktable, the sheet metal can be slid away from the cut area, making it easier for the operator to unload the cut part.

[0016] The plate cutting device provided in this application, compared with the prior art, after the plate is cut, lifts the position of the plate by a lifting frame to facilitate the operator to separate the cut parts; then the lifting frame slides the plate away from the cutting area to facilitate the operator to unload the cut parts.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figures 1 to 12 This application describes a sheet metal cutting device. The sheet metal cutting device includes a worktable 1 and several lifting frames 2. The top of the worktable 1 has several rows of serrated support components 11. Inner slides 12 and outer slides 13 are provided on both sides of the top of the worktable 1. A truss is provided on the worktable 1, spanning the worktable 1 and slidingly engaging with the outer slides 13. A laser cutting assembly is slidably mounted on the truss. Several lifting frames 2 span the worktable 1. Each lifting frame 2 slidesly with the inner slide 12. Each lifting frame 2 is provided with a clamping assembly 3 for clamping the edge of the sheet metal. The clamping assembly 3 slidesly with the lifting frame 2 in the height direction, and the height of the clamping assembly is greater than the thickness of the sheet metal. The width of the clamping assembly 3 is less than the distance between adjacent rows of serrated support components 11. When the laser cutting assembly cuts the sheet metal, the lifting frames 2 are located at one end of the worktable 1. After the laser cutting assembly finishes cutting, the lifting frames 2 are spaced apart in the sheet metal area.

[0021] The plate cutting device provided in this application, compared with the prior art, after the plate is cut, the position of the plate is raised by the lifting frame 2, which makes it easier for the operator to separate the cut parts; then the plate is slid away from the cutting area by the lifting frame 2, which makes it easier for the operator to unload the cut parts.

[0022] It should be noted that the driving method of the truss on the worktable 1 is existing technology, and the laser cutting component is also existing technology, which will not be described in detail here.

[0023] In some embodiments, such as Figures 1 to 12 As shown, each lifting frame 2 is provided with a clamping assembly 3 on both sides. Each clamping assembly 3 includes a sleeve 31 and a sliding component 32. The sleeve 31 slides with the lifting frame 2 along the height direction. The sleeve 31 has an opening on the side facing the plate. The sliding component 32 slides with the sleeve 31. One end of the sliding component 32 can extend out of the sleeve 31. The extended end of the sliding component 32 has a slot 321 that engages with the plate. The top and bottom surfaces of the slot 321 contact the top and bottom surfaces of the plate, respectively, to facilitate the upward sliding of the plate.

[0024] It should be noted that after the board is cut, the lifting frame 2 is slid to the board area; during the sliding of the lifting frame 2, the clamping component 3 is located above the saw tooth support component 11, so the saw tooth support component 11 will not interfere with the horizontal sliding of the clamping component 3; after the lifting frame 2 is slid to the designated position, the sleeve 31 and the sliding component 32 are slid down, and the sliding component 32 slides into the sleeve 31. There is a certain distance in the horizontal direction between the outer end of the sliding component 32 and the edge of the board, so the edge of the board will not affect the downward movement of the sliding component 32.

[0025] Since the width of the sleeve 31 is less than the distance between adjacent serrated support members 11, the sleeve 31 can slide to the position between adjacent serrated support members 11 so that the slot 321 on the sliding member 32 can be aligned with the edge of the board; then the sliding member 32 slides to the edge of the board and finally engages with the edge of the board.

[0026] After the sliding component 32 is inserted and engaged with the plate, the plate can be moved upward by sliding the sleeve 31, thereby separating the plate from the worktable 1. After the plate is separated from the worktable 1, if the cutting part is on the plate, the operator can knock the cutting part down onto the worktable 1 by tapping it with a tool.

[0027] In some embodiments, such as Figures 1 to 12As shown, the top surface of the slot 321 has a groove 322, and an abutment plate 33 is slidably disposed in the groove 322. The abutment plate 33 can press against the plate, and the outer peripheral wall of the abutment plate 33 contacts the inner peripheral wall of the groove 322. The top of the abutment plate 33 is rotatably provided with a clamping bolt 34, and the other end of the clamping bolt 34 protrudes through the sliding member 32. The sliding member 32 has a threaded hole that is threaded to engage with the clamping bolt 34. The distance between the abutment plate 33 and the clamping bolt 34 in the height direction is constant.

[0028] It should be noted that after the sliding component 32 is inserted and engaged with the edge of the plate, the clamping bolt 34 can be rotated to provide a downward clamping force to the abutment plate 33, thereby causing the abutment plate to press against the plate in the slot 321. With the above arrangement, the occurrence of separation between the plate and the sliding component 32 can be reduced.

[0029] A limiting plate 35 is welded to the threaded end of the tightening bolt 34. A limiting shell 36 is fitted onto the tightening bolt 34. The limiting shell 36 is fixed to the abutment plate 33 by bolts. That is, the limiting shell 36 has a through hole, and the abutment plate 33 has a threaded hole. The through hole on the limiting shell 36 is aligned with the threaded hole on the abutment plate 33, and then fixed by bolts. After the limiting shell 36 is fixed to the abutment plate 33, the bottom end of the limiting plate 35 contacts the top end of the abutment plate 33, the top end of the limiting plate 35 contacts the inner top wall of the limiting shell 36, and the outer peripheral wall of the limiting plate 35 contacts the inner peripheral wall of the limiting shell 36. This can play a limiting role and ensure the relative fixation of the tightening bolt 34 and the abutment plate 33 in the height direction.

[0030] Before welding the limiting plate 35, first put the limiting shell 36 on the tightening bolt 34, and then weld the limiting plate 35 onto the tightening bolt 34.

[0031] In some embodiments, such as Figures 1 to 12 As shown, the inner wall of the sleeve 31 has a guide groove 311, and the sliding component 32 has a guide block 323 that slides with the guide groove 311; wherein, a baffle 312 is fixedly provided at the opening of the sleeve 31 to limit the sliding position of the guide block 323.

[0032] It should be noted that there are two guide grooves 311 on the inner wall of the sleeve 31, and the two guide grooves 311 are arranged opposite to each other; the number of guide blocks 323 on the sliding component 32 is the same as the number of guide grooves 311, and the guide blocks 323 correspond one-to-one with the guide grooves 311; by slidingly engaging the guide blocks 323 with the guide grooves 311, and by fixing a baffle 312 at the opening of the guide grooves 311 in the sleeve 31, the sliding position of the guide blocks 323 can be limited, which can reduce the possibility of the sliding component 32 sliding out of the sleeve 31.

[0033] In some embodiments, such as Figures 1 to 12 As shown, the lifting frame 2 has an adjustment groove 21, an adjustment screw 22 is rotatably installed in the adjustment groove 21, and an adjustment component 23 that is threadedly engaged with the adjustment screw 22 is slidably installed in the adjustment groove 21. The adjustment component 23 is connected to the sleeve 31 to drive the sleeve 31 to rise and fall. Both sides of the lifting frame 2 have adjustment grooves 21, adjustment components 23 and adjustment screws 22. The two adjustment screws 22 are connected by a chain drive structure. The chain drive structure is set on the top of the lifting frame 2, and the top of the lifting frame 2 has a housing 4 to accommodate the chain drive structure. A servo motor 41 is installed on the top of the housing 4 at the position of one of the adjustment screws 22. The output shaft of the servo motor 41 is connected to the adjustment screw 22.

[0034] This embodiment uses three sets of lifting frames 2 as an example for explanation. The three sets of servo motors 41 are of the same model, each adjusting screw 22 has the same size, and each adjusting component 23 has the same size. The servo motors 41 on the three sets of lifting frames 2 are connected to the same controller, so it can be ensured that the three sets of servo motors 41 work at the same time. The transmission ratio of the chain drive structure between the two adjusting screws 22 is one to one, so it can be ensured that the rotational speed between the two adjusting screws 22 is the same.

[0035] It should be noted that a tension sprocket (not shown in the figure) is rotatably provided inside the housing 4, and the tension sprocket meshes with the chain 42; the bottom of the housing 4 contacts the bottom of the chain 42 to reduce the up-and-down swaying of the chain 42; a support sleeve 44 for supporting the sprocket 43 is connected to the bottom of the housing 4 to provide support for the sprocket 43; the sprocket 43 is keyed to the adjusting screw 22.

[0036] In some embodiments, such as Figures 1 to 12 As shown, the lifting frame 2 has a support groove 24 at the position after the adjusting component 23 slides. The support groove 24 is horizontally arranged and is a through groove. A support plate 25 is inserted into the support groove 24, and the support plate 25 can contact the bottom of the adjusting component 23. The support plate 25 is connected to the lifting frame 2 by a flexible rope, which can reduce the possibility of the support plate 25 being lost. The length of the flexible rope is sufficient to allow the support plate 25 to be inserted into the support groove 24.

[0037] It should be noted that by setting a support groove 24 on the lifting frame 2 and by inserting a support plate 25 into the support groove 24, the support plate 25 can provide support for the adjusting component 23. When the operator strikes the cutting part with a tool, the support plate 25 supports the adjusting component 23, which can reduce the downward movement of the adjusting component 23 and thus improve the stability of the clamping assembly 3.

[0038] In some embodiments, such as Figures 1 to 12As shown, in the initial position, the truss is located at one end of the workbench 1 and the lifting frame 2 is located at the other end of the workbench 1; a waste board collection box 5 is provided at one end of the lifting frame 2 on the workbench 1; when the board is slid to the end position of the workbench 1, the tightening bolt 34 is loosened and the board is slid horizontally outward, so that the board can fall into the waste board collection box 5, which is convenient for the subsequent centralized processing of waste boards.

[0039] For example, the end of the inner slide 12 is connected to a limiting plate 14, which can contact the side of one of the lifting frames 2 to limit the sliding position of the lifting frame 2. By providing a limiting plate 14 at the end of the inner slide 12, the extreme position of the lifting frame 2 can be limited, reducing the possibility of the lifting frame 2 falling off the worktable 1.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
