Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, and specifically, to a small cutting device for steel plate processing. Background Art

[0002] A stainless steel plate refers to a steel plate that resists corrosion by weak media such as the atmosphere, steam, and water. It is a type of alloy steel that is not easily rusted, but it is not completely rust-proof. The surface of the stainless steel plate is smooth, with high plasticity, toughness, and mechanical strength. During the processing of stainless steel plates, cutting equipment is usually required to cut the stainless steel plates horizontally and longitudinally.

[0003] The utility model with the authorization publication number of CN221270021U provides a stainless steel horizontal and vertical cutting device. By setting a workbench, a laser cutting machine, a pressing mechanism, a driving mechanism, and a rotating mechanism, the pressing mechanism is used to press the stainless steel plate onto the workbench. After the horizontal cutting of the stainless steel plate is completed by driving the laser cutting machine through the driving mechanism, the rotating mechanism drives the workbench to rotate, and the driving mechanism continues to drive the laser cutting machine to perform vertical cutting on the stainless steel plate.

[0004] In the above patent, after the operator places the steel plate on the processing table, four screws need to be rotated successively to press and fix the steel plate on the upper surface of the processing table to ensure the stability of the steel plate during the cutting process. After the cross-cutting of the steel plate is completed, the four screws need to be rotated in the reverse direction to release the pressing and fixing of the four steel plates one by one, and then the steel plate is removed from the processing table. Rotating the four screws one by one during the cutting process takes a lot of time, increasing the labor intensity of the operator and reducing the efficiency of cutting the steel plate. In view of this, we propose a small cutting device for steel plate processing. Summary of the Invention

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0026] Please refer toFigure 1 As shown in the figure, this embodiment provides a small cutting device for steel plate processing, including a frame 1. Inside the frame 1, there is a processing table 2. On the processing table 2, there is a pressing mechanism 3 and a guiding component 5. After placing the steel plate on the upper surface of the processing table 2, the guiding component 5 is used to finely adjust the position of the steel plate to make the cutting position of the steel plate more accurate. The pressing mechanism 3 presses and fixes the steel plate after the position is finely adjusted to improve the stability of the steel plate during cutting. At the top of the frame 1, there is a cutting component 6. The cutting component 6 cuts and processes the steel plate fixed on the processing table 2. Between the lower surface of the processing table 2 and the bottom surface inside the frame 1, there is a position adjustment mechanism 4. The position adjustment mechanism 4 drives the processing table 2 to rotate. After the cutting component 6 cuts the steel plate into two sections, the position adjustment mechanism 4 drives the steel plate placed on the processing table 2 to rotate 90 degrees, so that the cutting component 6 performs a cross-cut on the steel plate. When using the device, place the steel plate on the processing table 2, finely adjust the position of the steel plate and then press and fix it. After the cutting component 6 cuts the steel plate into two sections, rotate the processing table 2 by 90 degrees to adjust the position of the two sections of the steel plate, and then perform a secondary cut on the steel plate through the cutting component 6 to complete the cross-cut of the steel plate.

[0027] For the accuracy of the steel plate cut by the cutting component 6, the guiding component 5 is used to finely adjust the position of the steel plate so that multiple cut steel plates are all rectangles. The following details the structure of the guiding component 5. Refer to Figure 3 , the guiding component 5 includes a cross-cutting groove 51 opened on the top of the processing table 2. The cross-cutting groove 51 is composed of a horizontal groove and a vertical groove that are perpendicular to each other. Both the horizontal groove and the vertical groove are perpendicular to the side wall of the processing table 2. The cutting path of the cutting component 6 corresponds to the horizontal groove or the vertical groove, and the bottom surfaces of both the horizontal groove and the vertical groove are of an inverted V-shaped structure. When the chips generated by cutting the steel plate fall into the cross-cutting groove 51, the chips slide along the bottom surface of the cross-cutting groove 51 to the outside of the processing table 2, which is convenient for cleaning. At the same time, T-shaped blocks 53 are slidably connected to the inner walls of both the horizontal groove and the vertical groove. The horizontal section of the T-shaped block 53 is in contact with the upper surface of the processing table 2. After placing the steel plate at a predetermined position on the upper surface of the processing table 2, move the two T-shaped blocks 53 along the inner wall of the cross-cutting groove 51 successively until the horizontal section of the T-shaped block 53 is in contact with one side of the steel plate. Push the steel plate through the T-shaped block 53 to adjust the position of the steel plate so that the steel plate is completely in contact with one side of the horizontal section of the T-shaped block 53, thereby completing the fine adjustment of the position of the steel plate. The side wall of the finely adjusted steel plate is parallel to the side wall of the processing table 2, so that the cutting component 6 whose cutting path corresponds to the horizontal groove or the vertical groove cuts the steel plate into regular rectangles, which is convenient for subsequent processing of the steel plate.

[0028] ​On both sides of the vertical section of the T-shaped block 53, side plates 54 are symmetrically and fixedly connected. The side plates 54 are slidably arranged inside the inclined slots 52. When the T-shaped block 53 moves along the inner wall of the cross-cutting slot 51, the side plates 54 synchronously slide along the inner wall of the inclined slots 52. The cooperation between the side plates 54 and the inclined slots 52 restricts the upward movement of the T-shaped block 53 out of the cross-cutting slot 51, reducing the possibility of the loss of the T-shaped block 53. An inclined slot 52 is formed on the inner wall of the cross-cutting slot 51, and the end of the inclined slot 52 communicating with the cross-cutting slot 51 is located at a lower position, preventing chips from falling into the interior of the inclined slot 52 and affecting the sliding of the side plates 54.

[0029] In order to press and fix the steel plate after fine-tuning its position, the structure of the pressing mechanism 3 is refined as follows. Refer to Figure 2 , the pressing mechanism 3 includes four L-shaped pressing plates 31. The lower end of the vertical section of the L-shaped pressing plate 31 penetrates through the side wall of the processing table 2. The vertical section of the L-shaped pressing plate 31 can slide up and down on the processing table 2. The horizontal section of the L-shaped pressing plate 31 is arranged on the upper side of the processing table 2. Connecting rods 32 are symmetrically arranged below the processing table 2. Both ends of the connecting rod 32 are fixedly connected to the L-shaped pressing plate 31. The two L-shaped pressing plates 31 are connected together through the connecting rod 32. A lead screw 33 is threadedly connected to a position near the middle of the connecting rod 32. The lead screw 33 is arranged vertically. The upper end of the lead screw 33 is fixedly connected to a first gear 34. The first gear 34 is rotatably connected to the bottom of the processing table 2. When the lead screw 33 is rotated, due to the threaded connection between the lead screw 33 and the connecting rod 32, the connecting rod 32 moves upward along the axis of the lead screw 33. The upward moving connecting rod 32 drives the two L-shaped pressing plates 31 to move vertically, making the horizontal section of the L-shaped pressing plate 31 move away from the processing table 2. After placing the steel plate on the upper surface of the processing table 2 and positioning the steel plate below the horizontal sections of the four L-shaped pressing plates 31, the two lead screws 33 are rotated in the reverse direction, causing the four L-shaped pressing plates 31 to move vertically downward synchronously until the horizontal sections of the L-shaped pressing plates 31 press down the steel plate, so that the four L-shaped pressing plates 31 press and fix the steel plate on the upper surface of the processing table 2, restricting the movement of the steel plate during cutting and improving the stability of cutting.

[0030] In order to make the two lead screws 33 rotate synchronously to drive the four L-shaped pressing plates 31 to move vertically synchronously, a first gear 34 is fixedly connected to the upper end of the lead screw 33. The first gear 34 is rotatably connected to the bottom of the processing table 2. A second gear 35 is rotatably connected to the lower surface of the processing table 2. Both of the two first gears 34 are meshed with the second gear 35. The lower surface of the processing table 2 is symmetrically rotatably connected with a crank 36. The outer wall of the rotating shaft of the crank 36 is fixedly connected with a third gear 37. The third gear 37 is meshed with the second gear 35. When the crank 36 is rotated, the third gear 37 rotates synchronously. Through the meshing transmission between the third gear 37 and the second gear 35, the second gear 35 is driven to rotate. Through the meshing transmission between the second gear 35 and the third gear 37, the two first gears 34 are driven to rotate synchronously, and then the two lead screws 33 rotate synchronously to drive the four L-shaped pressing plates 31 to move vertically synchronously, and quickly press and fix the steel plate on the upper surface of the processing table 2.

[0031] In order to efficiently cut the steel plate corresponding to the opening path of the cross-cutting groove 51, the structure of the cutting assembly 6 is refined as follows. Refer to Figure 4 , the cutting assembly 6 includes a lifting frame 61 arranged inside the frame 1. A telescopic electric cylinder is fixedly connected to the top of the frame 1. The lower end of the telescopic electric cylinder is fixedly connected to the lifting frame 61. The lifting frame 61 is driven to move vertically by the telescopic movement of the telescopic electric cylinder. A laser cutting machine 62 is horizontally slidably connected inside the lifting frame 61. The laser cutting machine 62 is located above the processing table 2. The lifting frame 61 and the laser cutting machine 62 are driven to move vertically by the telescopic movement of the telescopic electric cylinder to adjust the height of the laser cutting machine 62 so that the laser cutting machine 62 can cut steel plates of different thicknesses. A reciprocating lead screw driven by a motor is arranged inside the lifting frame 61. The laser cutting machine 62 is threadedly connected to the reciprocating lead screw. When the output shaft of the motor drives the reciprocating lead screw to rotate, the laser cutting machine 62 moves horizontally along the inner wall of the lifting frame 61 through the threaded connection between the laser cutting machine 62 and the reciprocating lead screw. The moving path of the laser cutting machine 62 corresponds to the horizontal groove or vertical groove directly below the lifting frame 61. After the steel plate is fixed on the upper surface of the processing table 2, the telescopic electric cylinder is extended to drive the lifting frame 61 and the laser cutting machine 62 to move vertically downward, so that the laser cutting machine 62 approaches the steel plate. Then the laser cutting machine 62 is started, and the laser cutting machine 62 is moved corresponding to the horizontal groove or vertical groove of the cross-cutting groove 51 to perform laser cutting on the steel plate.

[0032] After the laser cutting machine 62 moves corresponding to the horizontal groove of the cross-cutting groove 51 and cuts the steel plate into two sections, by rotating the processing table 2 by 90 degrees, the vertical groove of the cross-cutting groove 51 is rotated to a position corresponding to the moving path of the laser cutting machine 62, and then the laser cutting machine 62 is moved corresponding to the vertical groove of the cross-cutting groove 51 to reset and perform secondary cutting on the steel plate, cutting the steel plate into four parts. The four parts of the steel plate are all regular rectangles. In order to drive the rotation of the processing table 2, the structure of the positioning mechanism 4 is refined as follows. Refer toFigure 2 , the position adjustment mechanism 4 includes a stepping motor 42 fixedly connected to the inner bottom surface of the frame 1. The output shaft of the stepping motor 42 is fixedly connected to the lower surface of the processing table 2. After the stepping motor 42 is started, its output shaft drives the processing table 2 to rotate. The rotation angle of the processing table 2 can be accurately adjusted by means of the stepping motor 42. The lower surface of the processing table 2 is rotatably connected to a support frame 41, and the lower end of the support frame 41 is fixedly connected to the inner bottom surface of the frame 1. The stepping motor 42 is arranged inside the support frame 41. The support frame 41 plays a role in supporting and guiding the processing table 2, improving the stability of the processing table 2 during rotation. By rotating the processing table 2, the laser cutting machine 62 can accurately complete the cross-cutting of the steel plate.

[0033] In summary, the working principle of this solution is as follows: After placing the steel plate on the upper surface of the processing table 2, move the T-shaped block 53 to a position where it contacts the side wall of the steel plate, and then finely adjust the position of the steel plate so that the steel plate is in full contact with the T-shaped block 53. Then rotate the crank 36 and the third gear 37 to drive the second gear 35 to rotate. The second gear 35 then drives the two first gears 34 to rotate synchronously, causing the two lead screws 33 to rotate synchronously, driving the four L-shaped pressing plates 31 to move vertically downward synchronously, quickly pressing and fixing the steel plate on the upper surface of the processing table 2. After lowering the height of the laser cutting machine 62, move the laser cutting machine 62 horizontally corresponding to the horizontal groove of the cross-cutting groove 51 to cut the steel plate into two sections. Then rotate the processing table 2 and the two sections of the steel plate fixed on the processing table 2 by 90 degrees, and move the laser cutting machine 62 corresponding to the vertical groove of the cross-cutting groove 51, so that the laser cutting machine 62 can accurately complete the cross-cutting of the steel plate and cut the steel plate into four regular rectangular steel plates.
