DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Example:

[0024] like Figures 1 to 8 As shown, an automatic punching device for aluminum profile processing described in an embodiment of the present invention includes a workbench 1, a fixed table 11 is fixedly connected to the upper surface of the workbench 1, a work box 12 is fixedly connected to the upper surface of the workbench 1, a punching head 13 is fixedly connected to the lower surface of the work box 12, a limiting member is arranged on the circumferential surface of the punching head 13, and the limiting member includes a positioning ring 14 fixedly connected to the circumferential surface of the punching head 13; a plurality of limiting blocks 15 fixedly connected to the circumferential surface of the positioning ring 14; a fixed column 16 fixedly connected to the lower surface of each limiting block 15, the internal elastic connection of the fixed column 16 to the limiting column 17; and a positioning plate 18 fixedly connected to the bottom end of each limiting column 17.

[0025] Specifically, in the process of using the above-mentioned aluminum sheet punching device, the aluminum sheet to be punched is placed on the central support plate, and then the punching cylinder is started to drive the punching part to move toward the aluminum sheet, so as to punch the aluminum sheet. However, in the process of punching, the aluminum sheet is not limited to a certain position, so the punching part will first exert an extrusion force on the aluminum sheet during the falling process, which may cause the aluminum sheet to move and cause dislocation, thereby causing the offset of the punching position, and producing unqualified punching parts. The punched circular aluminum sheet can still be processed in other ways, but its circumferential surface may produce burrs due to the wear of the punching part during the punching process, resulting in the need to grind the circular aluminum sheet separately, which is cumbersome and increases the production cost. Therefore, the present invention solves this problem by setting a certain structure. First, the aluminum plate to be punched is placed on the fixed table 11, and then the built-in hydraulic cylinder in the working box 12 is started, and then the punching head 13 is driven to approach the aluminum plate, and then the punching head 13 will squeeze and punch the aluminum plate. In the process of the punching head 13 abutting against the aluminum plate, a positioning ring 14 is fixedly connected to the circumferential surface of the punching head 13, and a plurality of limit blocks 15 are fixedly connected to the circumferential surface of the positioning ring 14, and then a fixing column 16 is fixedly connected to the lower surface of the limit block 15, and the internal telescopic elastic connection of the fixing column 16 is limited. The positioning plate 18 is fixed to the bottom end of the limiting column 17. When the punching head 13 abuts against the aluminum plate, the positioning plate 18 also abuts against the aluminum plate. Then, the punching head 13 continues to drop and punch, and the positioning plate 18 can pressurize and limit the aluminum plate. At this time, the limiting column 17 can be squeezed through the positioning plate 18 to extend and retract into the interior of the fixed column 16. Since a high-strength compression spring is arranged inside the fixed column 16, the compression spring will apply an opposite extrusion force, so that effective limiting can be achieved during the aluminum plate punching process, so that the part of the aluminum plate to be punched can achieve the effect of being pressed; The problem that the aluminum sheet is not limited in a certain position during the punching process, which results in an extrusion force on the aluminum sheet during the falling process of the punching part, may cause the aluminum sheet to move and be dislocated, thereby causing the offset of the punching position and producing unqualified punching parts. The round aluminum sheet punched can still be used for other metal processing, but its circumferential surface may produce burrs due to the wear of the punching part during the punching process, resulting in the need to grind the round aluminum sheet separately, which is cumbersome and increases the production cost.

[0026] like Figure 3 As shown, this embodiment also includes two positioning platforms 2 fixedly connected to the upper surface of the workbench 1, and the upper surface of each positioning platform 2 is fixedly connected to a first hydraulic cylinder 21; a clamping plate 23 fixedly connected to the output end of each first hydraulic cylinder 21, and the cross-section of each clamping plate 23 is concave. The two clamping plates 23 can be spliced ​​into a rectangle and can limit the aluminum plate.

[0027] Specifically, before the punching head 13 abuts against the aluminum plate, the steel plate is placed on the fixed table 11, and then the two first hydraulic cylinders 21 on the two positioning tables 2 on the upper surface of the workbench 1 are started. At this time, the two first hydraulic cylinders 21 will drive the clamping plates 23 fixed at their output ends to clamp and limit the aluminum plate, thereby achieving the positioning of the aluminum plate, preventing the aluminum plate from moving, and improving the quality of punching.

[0028] like Figure 4 As shown, in this embodiment, friction strips 25 are fixedly connected to both sides of the inner wall of each clamping plate 23, and the friction strips 25 are used to grind the burrs generated by cutting on both sides of the outer wall of the aluminum plate.

[0029] Specifically, when the two clamping plates 23 clamp the aluminum plate, the two friction strips 25 fixed on the inner walls of the clamping plates 23 can grind the edge of the aluminum plate through the friction strips 25 on both sides, thereby achieving the effect of improving the quality of the aluminum plate blanking parts.

[0030] like Figure 4 As shown, in this embodiment, a baffle 24 is fixedly connected to the upper surface of each clamping plate 23, and the baffle 24 is used to prevent the two ends of the aluminum plate from warping during the stamping process.

[0031] Specifically, while the clamping plate 23 clamps and limits the aluminum plate, a baffle 24 is fixed to the upper surface of the clamping plate 23, thereby achieving the effect of longitudinally limiting the aluminum plate, preventing the two ends of the aluminum plate from warping up due to uneven force during the punching process, thereby achieving a more stable punching effect on the aluminum plate.

[0032] Example:

[0033] like Figures 2 to 8 As shown, compared with Example 1, another implementation of the present invention is: a first cavity 28 is opened inside the fixed table 11, a first gear 210 is rotatably arranged in the middle of the first cavity 28, a first motor 29 is fixedly connected to the middle of the first gear 210, the first motor 29 is arranged inside the fixed table 11, the first gear 210 is meshed with a gear ring 213, the gear ring 213 is used for grinding the round aluminum sheet, a slot 27 is opened on one side of the fixed table 11, a connecting plate 22 is fixedly connected to the output end of the first hydraulic cylinder 21, a plug plate 26 is fixedly connected to the position of the connecting plate 22 corresponding to the slot 27, one end of the plug plate 26 is located directly below the gear ring 213, and a fixing hole 215 is opened on the fixed table 11 corresponding to the position of the punching head 13.

[0034] Specifically, after the punching is completed, the circular aluminum sheet will fall onto the plug plate 26, and then will be squeezed and positioned on the plug plate 26 under the extrusion of the punching head 13, and then the first motor 29 of the fixed table 11 will be started. After the first motor 29 is started, it will drive the first gear 210 to rotate, and the rotation of the first gear 210 can drive the gear ring 213 to rotate, and the rotation of the gear ring 213 can grind the circular aluminum sheet that falls between the plug plate 26 and the gear ring 213, thereby achieving the effect of saving costs.

[0035] like Figure 4 As shown, in this embodiment, the inner wall of the gear ring 213 is rotatably connected to a plurality of grinding rollers 214, and the grinding rollers 214 can abut against the circular aluminum sheet.

[0036] Specifically, when the gear ring 213 rotates, the plurality of grinding rollers 214 connected by the inner wall can grind the circumferential surface of the circular aluminum plate, thereby simplifying the process, shortening the grinding process, and improving work efficiency.

[0037] like Figure 4 As shown, in this embodiment, the first gear 210 is also meshed with the second gear 212, and a reciprocating screw 211 is fixedly connected to the middle of the second gear 212. The reciprocating screw 211 passes through the fixed table 11, and a storage frame 216 is fixedly connected to the lower surface of the fixed table 11. The storage frame 216 is used to reduce and absorb metal dust generated by grinding.

[0038] Specifically, when the first gear 210 rotates, it can also drive the second gear 212 meshing with it to rotate. After the second gear 212 rotates, it will drive the reciprocating screw 211 fixed in the middle thereof. After the reciprocating screw 211 is driven to rotate, it will drive the dust reduction parts on its circumferential surface. The dust reduction parts can spray water mist to absorb the dust debris generated by grinding, thereby reducing the diffusion of metal dust and protecting the surrounding working environment.

[0039] like Figure 4 As shown, in this embodiment, a partition 218 is fixedly connected to the inside of the storage frame 216, a third cavity 223 is opened on one side of the partition 218, a positioning plate 217 is slidably connected to the circumferential surface of the reciprocating screw 211, a plurality of spray holes 221 are opened on one side of the storage frame 216, and a plurality of connecting holes 222 are opened on one side of the storage frame 216.

[0040] Specifically, the rotation of the reciprocating screw 211 can drive the positioning plate 217 on its circumferential surface to move up and down. The up and down movement of the positioning plate 217 will squeeze the third cavity 223 on one side of the partition 218, thereby increasing the pressure on the third cavity 223 and spraying the water inside it from the nozzle to the position where the circular aluminum plate falls. At the same time, a number of connecting holes 222 are opened on one side of the storage frame 216 to balance the pressure and achieve a better maintenance working environment.

[0041] like Figure 4 As shown, in this embodiment, a slider 220 is fixedly connected to one side of the positioning plate 217 , and a slide groove 219 is provided at a position of the partition plate 218 corresponding to the slider 220 , so that the positioning plate 217 can slide stably along the slide groove 219 through the slider 220 .

[0042] Specifically, by fixing a slider 220 on one side of the positioning plate 217 and then providing a slide groove 219 at a position of the partition plate 218 corresponding to the slider 220 , the positioning plate 217 can slide stably along the slide groove 219 through the slider 220 .

[0043] like Figure 4 As shown, in this embodiment, a collection frame 3 is provided inside the workbench 1, and a collection groove 34 is snap-connected inside the collection frame 3. An elastic net 35 is fixedly connected to the bottom surface of the collection groove 34. Two connecting blocks 31 are fixedly connected to the bottom end of the collection frame 3. A connecting groove 32 is opened at the position of each connecting block 31 of the workbench 1. A handle 33 is fixedly connected to the outer wall of the collection frame 3. The collection frame 3 can slide out of the workbench 1 along the connecting groove 32 through the two connecting blocks 31.

[0044] Specifically, when the round aluminum plate is polished, the first hydraulic cylinder 21 on the positioning table 2 will also retract, and then the insert plate 26 will be pulled back at the same time, causing the round aluminum plate to fall into the collection frame 3 that is slidably connected to the workbench 1. A collection groove 34 is clamped in the collection frame 3, and an elastic net 35 is fixed to the bottom end of the collection groove 34, thereby reducing the bumps of the round aluminum plate when it falls to a certain extent, achieving the effect of protecting the round aluminum plate and achieving effective recycling.

[0045] Working principle: first, the aluminum plate to be punched is placed on the fixed table 11. After the steel plate is placed on the fixed table 11, the two first hydraulic cylinders 21 on the two positioning tables 2 on the upper surface of the workbench 1 are started. At this time, the two first hydraulic cylinders 21 will drive the clamping plates 23 fixed at their output ends to clamp and limit the aluminum plate, thereby achieving the positioning of the aluminum plate and preventing the aluminum plate from moving, thereby improving the quality of punching. In the process of the two clamping plates 23 clamping the aluminum plate, the two friction strips 25 fixed on both sides of the inner wall of the clamping plate 23 can grind the edge of the aluminum plate through the friction strips 25 on both sides, thereby achieving the effect of improving the quality of aluminum plate punching parts; Then, the built-in hydraulic cylinder in the working box 12 is started, and the punching head 13 is driven to approach the aluminum plate, and then the punching head 13 will squeeze and punch the aluminum plate. In the process of the punching head 13 abutting the aluminum plate, a positioning ring 14 is fixedly connected to the circumferential surface of the punching head 13, and a plurality of limit blocks 15 are fixedly connected to the circumferential surface of the positioning ring 14, and then a fixing column 16 is fixedly connected to the lower surface of the limit block 15, and the internal telescopic elastic connection of the fixing column 16 is connected to the limit column 17, and then a positioning plate 1 is fixedly connected to the bottom end of the limit column 17 8. When the punching head 13 abuts against the aluminum plate, the positioning plate 18 will also abut against the aluminum plate. Then, the punching head 13 continues to drop and punch, and the positioning plate 18 can pressurize and limit the aluminum plate. At this time, the positioning plate 18 can squeeze the limiting column 17 to extend into the interior of the fixed column 16, and since a high-strength compression spring is arranged inside the fixed column 16, the compression spring will apply an opposite extrusion force, thereby achieving effective limiting in the process of punching the aluminum plate, so that the part of the aluminum plate to be punched can achieve the effect of being pressed; After the punching is completed, the circular aluminum sheet will fall onto the insert plate 26, and then will be squeezed and positioned on the insert plate 26 under the extrusion of the punching head 13, and then the first motor 29 of the fixed platform 11 will be started. After the first motor 29 is started, it will drive the first gear 210 to rotate, and the rotation of the first gear 210 can drive the gear ring 213 to rotate, and the rotation of the gear ring 213 can grind the circular aluminum sheet falling between the insert plate 26 and the gear ring 213, thereby achieving the effect of cost saving. When the round aluminum plate is polished, the first hydraulic cylinder 21 on the positioning table 2 will also retract, and then the insert plate 26 will be withdrawn at the same time, causing the round aluminum plate to fall into the collection frame 3 slidably connected to the workbench 1, and a collection groove 34 is clamped in the collection frame 3, and an elastic net 35 is fixed to the bottom end of the collection groove 34, thereby reducing the bumping of the round aluminum plate when it falls to a certain extent, achieving the effect of protecting the round aluminum plate and achieving effective recycling; Finally, the aluminum blanking is completed.
