Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and more specifically, to a full-brightness strip punching device for aluminum profiles. Background Technology

[0002] Full-brightness strip punching: refers to the high-gloss, burr-free, tear-free finish achieved in aluminum profile punching, with low surface roughness, suitable for direct use in exterior parts or precision assemblies. An existing publication (CN217665719U) describes a mold structure for improving the full-brightness stripe finish of punched sections. It includes a lower mold and an upper die. The upper mold houses a punching mechanism, and the lower mold houses a clamping mechanism. The punching and clamping mechanisms are arranged vertically and vertically. The punching mechanism includes a punch and an upper spring for downwardly supporting the punch. The clamping mechanism includes a ejector float that moves within the lower mold and a lower spring for upwardly supporting the ejector float.

[0003] However, in the above scheme, after the stamping mechanism and the clamping mechanism stamp the sheet metal, the molded part will be stuck in the forming cavity of the lower mold and needs to be manually removed by the staff. This not only increases the workload of the staff, but also the small space inside the forming cavity requires the staff to spend a certain amount of time to remove the molded part. During this period, the mold cannot be used, reducing production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a full-brightness strip punching equipment for aluminum profiles, which can effectively solve the problem in the background technology that after the stamping mechanism and the clamping mechanism punch the sheet metal, the formed part will be stuck in the forming cavity of the lower die, which requires the operator to manually remove it. This not only increases the workload of the operator, but also the small space inside the forming cavity requires the operator to spend a certain amount of time to remove the formed part. During this period, the die cannot be used, which reduces production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A full-brightness strip punching equipment for aluminum profiles includes a base. Two positioning rods are fixedly installed on both sides of the upper surface of the base. A support plate is fixedly installed on the upper end of each positioning rod. A hydraulic cylinder is fixedly installed in the middle of the upper surface of the support plate. The output end of the hydraulic cylinder passes through the support plate and a lifting plate is installed thereon. The lifting plates are slidably arranged on one side of each positioning rod.

[0007] The lower surface of the lifting plate is provided with a punch structure, the upper surface of the base is provided with a mold, and the lower surface of the base is provided with an ejection assembly for ejecting the molded part.

[0008] Preferably, the ejection assembly includes a mounting groove, which is formed on the lower surface of the base. Several connecting rods are slidably disposed through the lower surface of the mounting groove, and the upper end of each connecting rod extends into the mold and is jointly fixedly mounted with an annular top plate.

[0009] Preferably, a crossbar is rotatably installed between the two sides of the inner wall of the mounting groove, and an eccentric wheel is sleeved in the middle of the crossbar.

[0010] A circular plate is fixedly installed at the lower end of each of the connecting rods.

[0011] Preferably, gears are fitted on both sides of the crossbar, and racks are slidably disposed through both sides of the top of the mounting groove, with the two racks meshing with the corresponding gears respectively;

[0012] Mounting brackets are fixedly installed on both sides of the punch structure, and the upper ends of the two racks are respectively fixedly connected to the corresponding mounting brackets.

[0013] Preferably, each of the connecting rods is fitted with an elastic element capable of compression and resetting.

[0014] Preferably, the elastic element is a spring.

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

[0016] (1) After the punch structure presses the sheet metal, the operator controls the connecting rod to move, so that the connecting rod drives the annular top plate to rise, so that the annular top plate can lift the material in the forming cavity, thereby ejecting the material out of the forming cavity. The operator does not need to manually remove the material, which reduces the workload of the operator and shortens the material removal time. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-5 As shown, a full-brightness strip punching equipment for aluminum profiles includes a base 1. Two positioning rods 2 are fixedly installed on both sides of the upper surface of the base 1. A support plate 3 is fixedly installed on the upper end of each positioning rod 2. A hydraulic cylinder 4 is fixedly installed in the middle of the upper surface of the support plate 3. The output end of the hydraulic cylinder 4 passes through the support plate 3 and a lifting plate 5 is installed thereon. The lifting plate 5 is slidably arranged on one side of the rod body of each positioning rod 2.

[0025] The lower surface of the lifting plate 5 is provided with a punch structure 6, the upper surface of the base 1 is provided with a mold 7, and the lower surface of the base 1 is provided with an ejection assembly 8 for ejecting the molded part.

[0026] The ejection assembly 8 includes a mounting groove 801, which is formed on the lower surface of the base 1. Several connecting rods 802 are slidably disposed through the lower surface of the mounting groove 801. The upper end of each connecting rod 802 extends into the mold 7 and is fixedly mounted on an annular top plate 803.

[0027] The worker places the sheet material between the punch structure 6 and the mold 7. Then, the worker activates the hydraulic cylinder 4, causing its output end to move the lifting plate 5, which lowers the punch structure 6. After the punch structure 6 punches the sheet material, the worker controls the connecting rod 802 to move, causing the connecting rod 802 to raise the annular top plate 803. This allows the annular top plate 803 to lift the material in the forming cavity, thus ejecting the material from the forming cavity. This eliminates the need for the worker to manually remove the material, reducing the workload and shortening the material removal time.

[0028] In another embodiment of the present invention, a crossbar 9 is rotatably installed between the two sides of the inner wall of the mounting groove 801, and an eccentric wheel 10 is sleeved in the middle of the crossbar 9.

[0029] A circular plate 1001 is fixedly installed at the lower end of each connecting rod 802.

[0030] The staff controls the horizontal bar 9 to rotate. Under the pushing action generated by the rotation of the eccentric wheel 10, the circular plate 1001 can drive the connecting rod 802 and the annular top plate 803 to rise and fall.

[0031] In another embodiment of this utility model, gears 11 are sleeved on both sides of the crossbar 9, and racks 12 are slidably disposed through both sides of the top of the mounting groove 801, with the two racks 12 meshing with the corresponding gears 11 respectively.

[0032] The punch structure 6 has mounting brackets 601 fixedly installed on both sides, and the upper ends of the two racks 12 are fixedly connected to the corresponding mounting brackets 601 respectively.

[0033] In another embodiment of this utility model, when the punch structure 6 is raised and lowered, the rack 12 is raised and lowered, and the rack 12 and the gear 11 are in contact.

[0034] In another embodiment of this utility model, each connecting rod 802 is fitted with an elastic element 13 capable of compression and reset.

[0035] The elastic element 13 is a spring.

[0036] By setting a spring, after the annular top plate 803 rises, when the eccentric wheel 10 stops pushing the circular plate 1001, the spring can push the circular plate 1001, causing it to move the annular top plate 803 back to its original position. This avoids the situation where the two sides of the annular top plate 803 rub against the inner wall of the forming cavity of the mold 7, which would prevent the annular top plate 803 from being unable to move to its original position.

[0037] The working principle of this type of aluminum profile full-brightness strip punching equipment:

[0038] In use, the operator places the sheet material between the punch structure 6 and the mold 7. Then, the operator activates the hydraulic cylinder 4, causing its output end to move the lifting plate 5, which lowers the punch structure 6. After the punch structure 6 punches the sheet material, the operator controls the connecting rod 802 to move, causing the connecting rod 802 to raise the annular top plate 803. This allows the annular top plate 803 to lift the material in the forming cavity, thus ejecting the material from the forming cavity. This eliminates the need for the operator to manually remove the material, reducing the workload and shortening the material removal time.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
