Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to a multi-station punching device for aluminum profile processing. Background Art

[0002] Strip aluminum buckle strips are generally used for house soft decoration, such as in bathrooms, kitchens, etc. Some are also used for office decoration. The aluminum buckle strips used in the kitchen are buckled on the wooden surface of the cabinet and table body to prevent the wood from deformation and mildew, facilitate cleaning, increase texture, and facilitate cleaning. Most aluminum buckle strips are not load-bearing, so their thickness is relatively thin, usually 0.3mm-0.6mm.

[0003] In order to facilitate the installation of components, it is necessary to Figure 8 The U-shaped aluminum buckle strip shown in the figure is punched. There are currently two punching methods.

[0013] Preferably, a rotary joint is installed on the delivery pipe, and the rotary joint is fixedly connected to the return pipe and the outlet pipe.

[0014] Preferably, a semiconductor refrigeration sheet is installed on the water tank, and a radiator is installed at the heating end of the semiconductor refrigeration sheet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] A hollow multi-prism is set up with a simple and stable structure, which is used to realize the switching of multiple workstations, avoiding the disadvantages of the existing technology that multiple workstations occupy a large space and the equipment is inconvenient to transport. The driving part above it is used as the power, and the driving mechanism is used to drive the hollow multi-prism to rotate, so that the U-shaped aluminum gusset plate can be loaded, positioned, limited and locked, etc. There is no need to wait for the previous U-shaped aluminum gusset plate to be removed before punching, and the punching process has strong continuity, which greatly improves the punching efficiency.

[0017] A locking component is also designed, which is also driven by the punching mechanism to lock the hollow multi-prism after rotation. The designed L-shaped block realizes the correction and limit of the product during the locking process to ensure that each U-shaped aluminum gusset plate can be aligned with the punch to ensure the quality of the punching process. The locking component uses the inclined surface to change the transmission direction. The structure is ingenious and highly adaptable to the punching process. It can be automatically locked before punching, and after the locking is completed, it can support the hollow multi-prism, allowing the punching process to proceed smoothly and stably.

[0018] In the present invention, the process of placing the U-shaped aluminum gusset plate is located before punching. Because of the above-mentioned rotation design, dislocation loading can be realized, and because the limit can be automatically corrected, the loading operation has a certain fault tolerance and reduces the accuracy requirement; the rotation realizes the station switching, and can also realize automatic unloading, and the gravity of the U-shaped aluminum gusset plate itself is used to realize the unloading work, and the debris generated by punching can also be discharged without manual participation. In the above process, dislocation of loading, reduced accuracy, and automatic unloading can improve punching efficiency and safety.

[0019] By setting up a piston cylinder, a water tank and a movable piston, cooling water can be transported into the hollow multi-prism to cool and dissipate the heat of the processed U-shaped aluminum gusset plate. When the moisture in the air encounters the hollow multi-prism with a temperature lower than the ambient temperature, it will liquefy into water droplets on the hollow multi-prism, which will lubricate the U-shaped aluminum gusset plate placed in the strip groove, so as to facilitate material discharge, correction and unloading.

[0020] In summary, the present invention avoids the low punching efficiency and potential safety hazards of the prior art. By setting up multi-station hollow multi-prisms distributed in a ring shape, it not only reduces the overall volume of the equipment, but also can realize the correction, limiting and cooling functions of the U-shaped aluminum gusset plate.

DETAILED DESCRIPTION

[0030] 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.

[0031] Reference Figure 1-Figure 7 A multi-station punching device for aluminum profile processing includes a stand and a punching mechanism, including a base 1. The stand includes a base 1, four support columns 2 are fixed on the base 1, and a mounting plate 3 is fixed on the four support columns 2. The punching mechanism includes a driving member 4 installed on the mounting plate 3, wherein the driving member 4 is a hydraulic cylinder, and a lifting plate 14 is installed at the output end of the driving member 4, and a punching plate 37 is installed at the bottom of the lifting plate 14. A plurality of punches 38 are fixed at the bottom of the punching plate 37, and the distribution of the punches 38 is the same as the distribution of holes required for installing fan blades on the U-shaped aluminum buckle plate.

[0032] The rotating switching mold assembly is a hollow polygonal column 11, and a mounting frame 10 is fixed on the base 1. Two rotatable conveying pipes 19 are passed through the mounting frame 10. The two conveying pipes 19 are fixed with the hollow polygonal column 11 connected thereto. A limiting groove group for cooperating with the placement of aluminum profiles and the use of the punch 38 is provided on the plane 16 of the hollow polygonal column 11. The limiting groove group includes two strip grooves 18 and a plurality of punching grooves 17 arranged on the plane 16. The plurality of punching grooves 17 are arranged in cooperation with the punch 38, and a plurality of punching grooves 17 are located between the two strip grooves 18.

[0033] A driving mechanism for driving the two conveying pipes 19 to rotate synchronously is installed on the lifting plate 14. The driving mechanism rotates the hollow multi-prism 11 to rotate at a fixed angle and keep it stationary. The driving mechanism includes a connecting plate 25 fixed on the lifting plate 14. The bottom of the connecting plate 25 is fixedly connected to a rectangular sleeve 22. A rectangular rod 23 is slidably connected in the rectangular sleeve 22. A first spring 36 is fixed to the upper end of the rectangular rod 23. The upper end of the first spring 36 is fixedly connected to the bottom of the connecting plate 25. A rack plate 24 is fixed to the bottom of the rectangular rod 23. A one-way bearing 41 is fixedly connected to the conveying pipe 19. A gear 20 meshing with the rack plate 24 is fixed on the one-way bearing 41. Figure 5 As shown, the hollow polygonal column 11 is a decagonal column, so the hollow polygonal column 11 stops after rotating 36° each time.

[0034] In order to ensure that the rack plate 24 can move up and down stably, a limiting mechanism for limiting the position of the rack plate 24 is also included. The limiting mechanism includes a short rod 29 fixedly mounted on the mounting frame 10. The short rod 29 is rotatably connected to a limiting wheel 30. The limiting wheel 30 abuts against the rack plate 24. The limiting wheel 30 abuts against the flat part on the rear side of the rack plate 24. In this way, the rack plate 24 can be limited, and the rack plate 24 can move up and down stably.

[0035] In order to cushion the rack plate 24 , a rubber block 12 is fixed to the base 1 . The rubber block 12 is directly opposite to the rack plate 24 , and can cushion and protect the rack plate 24 .

[0036] After the hollow polygonal column 11 is stationary, one of the planes 16 is opposite to the punch 38 , and the driving member 4 drives the lifting plate 14 to move up and down, and cooperates with the driving mechanism to punch holes in the aluminum profiles on the hollow polygonal column 11 one by one.

[0037] In order to ensure stability during punching, two locking components are also included to lock the hollow polygonal column 11 rotating at a fixed angle. The locking component includes a moving rod 32 that passes through the mounting frame 10 and is slidably connected thereto. A first wedge block 28 is fixed on the moving rod 32. A second spring 42 is fixed on the first wedge block 28. The second spring 42 is fixedly connected to the mounting frame 10. An L-shaped block 31 is fixed on the moving rod 32. A limiting column 33 is fixed on the L-shaped block 31. A plurality of slots 34 distributed in a ring array are provided at the end of the hollow polygonal column 11. The slots 34 are matched with the limiting columns 33. An L-shaped plate 26 is fixed on the lifting plate 14. A second wedge block 27 is fixed on the L-shaped plate 26. The second wedge block 27 is matched with the first wedge block 28.

[0038] Since the stamping process generates heat, in order to dissipate the heat of the U-shaped aluminum gusset plate, it also includes a conveying mechanism that can inject cooling water into the hollow polygonal column 11. The conveying mechanism includes a water tank 5 installed on the mounting plate 3. A semiconductor refrigeration plate 35 is installed on the water tank 5. The water in the water tank 5 can be cooled by the semiconductor refrigeration plate 35. A radiator is installed at the heating end of the semiconductor refrigeration plate 35 to ensure the stable operation of the semiconductor refrigeration plate 35.

[0039] A piston cylinder 13 is installed at the bottom of the mounting plate 3, and a movable piston 39 is slidably connected in the piston cylinder 13. A connecting rod 40 is fixed to the bottom of the movable piston 39, and the connecting rod 40 is fixedly connected to the upper end of the lifting plate 14. The piston cylinder 13 is connected to the water tank 5 through a water inlet pipe 9, and a first one-way valve 15 is installed on the water inlet pipe 9. The first one-way valve 15 only allows the cooling water in the water inlet pipe 9 to flow into the piston cylinder 13; a water outlet pipe 7 is installed on the piston cylinder 13, and a second one-way valve 8 is installed on the water outlet pipe 7. The second one-way valve 8 only allows the water in the piston cylinder 13 to flow into the water outlet pipe 7.

[0040] The water outlet pipe 7 is rotatably connected to the delivery pipe 19, and the delivery pipe 19 on the other side is rotatably connected to the return pipe 6, and the return pipe 6 is connected to the water tank 5. A rotary joint 21 is installed on the delivery pipe 19, and the rotary joint 21 is fixedly connected to the return pipe 6 and the water outlet pipe 7. The setting of the rotary joint 21 can ensure stable delivery of cooling water without affecting the rotation of the delivery pipe 19.

[0041] When the present invention is used, the U-shaped aluminum gusset plate can be placed in the two strip grooves 18 by a robot or manually. The strip grooves 18 here are located in a position close to the punch 38. The strip grooves 18 here are inclined, so the U-shaped aluminum gusset plate will not fall off when it is placed in the strip grooves 18 here.

[0042] The driving member 4 drives the lifting plate 14, the punching plate 37 and the punch 38 to move downward, the lifting plate 14 moves downward to drive the connecting plate 25 to move downward, the connecting plate 25 moves downward to drive the rectangular sleeve 22, the first spring 36 and the rectangular rod 23 to move downward, the rectangular rod 23 moves downward to drive the rack plate 24 to move downward, the rack plate 24 moves downward to drive the gear 20 to rotate, the rotation of the gear 20 drives the one-way bearing 41 to rotate, the rotation of the one-way bearing 41 drives the conveying pipe 19 to rotate, so that the hollow multi-prism 11 can be rotated, when the rack plate 24 abuts against the rubber block 12, the rack plate 24 cannot move downward at this time, and drives the conveying pipe 19 to rotate at an angle of 36°. The U-shaped aluminum buckle plate placed in this way is opposite to the punch 38. Since the rack plate 24 cannot move downward, when the driving member 4 drives the lifting plate 14 to move downward, relative sliding occurs between the rectangular sleeve 22 and the rectangular rod 23, and the first spring 36 is compressed;

[0043] The downward movement of the lifting plate 14 also drives the L-shaped plate 26 and the second wedge block 27 to move downward. As the lifting plate 14 moves downward, the second wedge block 27 abuts against the first wedge block 28, and can drive the second wedge block 27 to move under pressure. The movement of the second wedge block 27 drives the moving rod 32, the L-shaped block 31 and the limiting column 33 to move. The movement of the L-shaped block 31 can push the U-shaped aluminum gusset plate located outside the strip groove 18 into the strip groove 18. Finally, the inner bottom of the L-shaped block 31 slides against the upper end of the U-shaped aluminum gusset plate, and the vertical surface of the L-shaped block 31 abuts against the U-shaped aluminum gusset plate. In this way, the U-shaped aluminum gusset plate can be corrected to ensure that the position where it needs to be punched corresponds to the punch 38, and at the same time, the U-shaped aluminum gusset plate is limited to ensure the stability of the punching.

[0044] It should be noted that the rack plate 24 is meshed with the gear 20 at this time;

[0045] At this time, the limiting column 33 is also inserted into the card slot 34, so that the hollow multi-prism 11 can be clamped and limited, so that it is not easy to rotate, thereby ensuring the stability of the U-shaped aluminum gusset plate punching; at the same time, it also plays a role in supporting the hollow multi-prism 11, and the force generated during the punching can be shared to the limiting column 33, thereby reducing the supporting force borne by the conveying pipe 19, and protecting the conveying pipe 19;

[0046] Finally, the punch 38 abuts against the U-shaped aluminum gusset plate to punch the U-shaped aluminum gusset plate, and the waste generated by the punching falls into the punching slot 17;

[0047] When the driving member 4 drives the lifting plate 14, the punch 38, etc. to move upward, since the U-shaped aluminum gusset plate is limited by the L-shaped block 31, the upward movement of the punch 38 will not drive the U-shaped aluminum gusset plate to move upward. As the lifting plate 14 moves upward, the first wedge block 28 and the second wedge block 27 separate, and then the rectangular sleeve 22 and the rectangular rod 23 slide relative to each other and reset, and finally drive the rack plate 24 to move upward. The upward movement of the rack plate 24 drives the gear 20 to rotate. Under the action of the one-way bearing 41, the gear 20 and the conveying pipe 19 rotate relative to each other, that is, the conveying pipe 19 remains stationary at this time;

[0048] During the above-mentioned stamping process, the U-shaped aluminum gusset plate can be placed into the strip groove 18 for subsequent processing;

[0049] As the hollow multi-prism 11 rotates, when the U-shaped aluminum gusset plate after punching is rotated to the lower side, it will be separated from the strip groove 18 due to gravity and can be collected by a collection box or transported by a conveyor belt, and the waste chips in the corresponding punching groove 17 will also fall and be discharged;

[0050] Repeat the above steps to punch holes on the U-shaped aluminum gusset plates at multiple stations on the hollow multi-prism 11 one by one.

[0051] In addition, the lifting plate 14 moves downward, driving the connecting rod 40 and the movable piston 39 downward, so that the cooling water in the water tank 5 can be sucked into the piston cylinder 13 through the water inlet pipe 9. When the lifting plate 14 moves upward, the lifting plate 14 drives the connecting rod 40 and the movable piston 39 upward, and the cooling water in the piston cylinder 13 can be transported to the hollow multi-prism 11 through the water outlet pipe 7 and the delivery pipe 19. This reciprocating movement increases the cooling water in the hollow multi-prism 11 and finally transports it to the water tank 5 through the return pipe 6; through the rotating hollow multi-prism 11, the cooling water can fully contact the hollow multi-prism 11 and exchange heat with it, thereby reducing the heat generated on the U-shaped aluminum gusset plate, so that it can be manually taken for further processing;

[0052] In addition, since the cooling water exchanges heat with the hollow polygonal prism 11 to lower its temperature, when the moisture in the air encounters the hollow polygonal prism 11 whose temperature is lower than the ambient temperature, it will liquefy into water droplets on the hollow polygonal prism 11, thereby lubricating the U-shaped aluminum gusset plate placed in the strip groove 18, making the U-shaped aluminum gusset plate move more smoothly in the strip groove 18, which is convenient for discharging, correction and unloading.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
