Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular to an aluminum alloy punching device. Background Art

[0002] Aluminum alloy punching refers to the process of forming regularly arranged holes on aluminum alloy plates or profiles by mechanical processing. This process usually uses special punching equipment, with molds (punches and lower molds) of different shapes and sizes, to partially separate the material under pressure, thereby realizing the forming of holes. According to demand, various geometric shapes such as round, square, and oval holes can be made. However, the current punching machines usually punch a single number of holes. Therefore, for six aluminum alloy parts that need to be punched, this punching device needs to be used. Six punchings are required to meet the requirements, resulting in low punching efficiency. In addition, this punching method must ensure the accuracy of the hole position during punching. If there is a deviation, the punched aluminum alloy parts will not meet the product requirements and affect product quality. Summary of the invention

[0003] The present invention is intended to provide an aluminum alloy punching device to solve the problem of low efficiency when punching multiple holes in an aluminum alloy part.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an aluminum alloy punching device, comprising a punch and a lower die, the punch comprising a connecting plate, the connecting plate is fixedly connected to the punching slide of the punching machine, both ends of the connecting plate are slidably connected with vertical guide rods, springs are sleeved on the two guide rods, the bottom ends of the two guide rods are fixedly connected with the same movable plate, and the movable plate is parallel to the connecting plate; the lower surface of the connecting plate is fixedly connected with a stamping plate, the lower surface of the stamping plate is provided with a plurality of stamping columns, the movable plate is provided with a plurality of through holes, and the plurality of through holes are located directly below the plurality of stamping columns and correspond one to one;

[0005] The lower surface of the lower die is fixedly connected with a fixing plate, which is horizontally fixedly connected to the punching table of the punch press, and the fixing plate is provided with an avoidance opening. The lower die is provided with a die hole used in conjunction with the punching column, and the bottom end of the die hole is connected to the avoidance opening.

[0006] The working principle of the present invention is as follows: when in use, the aluminum alloy part to be punched is placed on the surface of the lower die, and then the punch press is started. When the punch press is started, the connecting plate is driven downward by the downwardly moving stamping slider, and the movable plate is driven downward by two guide rods when the connecting plate moves downward. The movable plate moves downward until it contacts the aluminum alloy part and presses the aluminum alloy part so that it cannot move. While the stamping slider moves downward, the stamping slider drives the stamping plate and a plurality of stamping columns to move downward through the connecting plate, and the stamping columns pass through the through holes when moving downward, and punch the aluminum alloy part by shear force, and the waste punched off the aluminum alloy part is pressed into the die hole of the lower die and falls from the avoidance opening. At this time, the punching of the aluminum alloy part is completed, and when the movable plate presses the aluminum alloy part, the connecting plate continues to move downward, and the two guide rods are inserted into the connecting plate, and the connecting plate compression spring is in a compressed state. After the punching slide of the punch press starts to move upward, the connecting plate starts to move upward, and then drives multiple punching columns to move upward through the punching plate. At this time, the movable plate still presses the aluminum alloy part under the elastic force of the spring, so multiple punching columns can be pulled out of the aluminum alloy part when moving upward.

[0007] Beneficial effects of the present invention:

[0008] 1. This solution can provide multiple punching columns on the punching plate, so that multiple holes can be punched simultaneously in one operation, which significantly improves the punching efficiency.

[0009] 2. In this solution, the position of the punching column is fixed, so after the punching is completed, the spacing between the punching holes can be ensured to be consistent, ensuring the accuracy of the punching of the aluminum alloy parts and ensuring the product quality.

[0010] 3. The stamping column presses the waste directly into the die hole of the lower die and discharges it through the avoidance port. This method not only avoids the accumulation of waste and affects subsequent processing, but also facilitates the collection and recycling of these wastes, reflecting the concept of environmental protection.

[0011] Furthermore, a waste box is provided below the escape opening, and the top of the waste box is open, so as to collect the aluminum alloy waste dropped from the escape opening by the waste box for recycling.

[0012] Furthermore, the upper surface of the lower die is provided with a groove for placing the aluminum alloy. The purpose is to ensure that the aluminum alloy piece is placed accurately through this arrangement, thereby ensuring the punching accuracy.

[0013] Furthermore, a transverse telescopic rod is fixedly connected to the side wall of the lower die, and a vertical limit plate is fixedly connected to the end of the telescopic rod away from the lower die, and the limit plate is used to form abutment against the aluminum alloy part to limit the movement of the aluminum alloy part. The purpose is that through this arrangement, the length of the telescopic rod can be adjusted according to the position where the hole needs to be punched on the aluminum alloy part, and then the position of the limit plate can be moved. In this way, when placing the aluminum alloy part, the end of the aluminum alloy part can be directly abutted against the limit plate and the aluminum alloy part can be placed in accordance with the position of the groove to ensure the accuracy of the punching position during punching.

[0018] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown:

[0019] An aluminum alloy punching device comprises a punch and a lower die 14, the punch comprises a connecting plate 2, the connecting plate 2 is fixedly connected to a punching slide 1 of a punching machine, both ends of the connecting plate 2 are slidably connected with vertical guide rods 4, springs 3 are sleeved on the two guide rods 4, the bottom ends of the two guide rods 4 are fixedly connected with the same movable plate 7, and the movable plate 7 is parallel to the connecting plate 2; a stamping plate 5 is fixedly connected to the lower surface of the connecting plate 2, six stamping columns 6 are arranged on the lower surface of the stamping plate 5, six through holes 17 are arranged on the movable plate 7, and the six through holes 17 are located directly below the six stamping columns 6 and correspond one to one;

[0020] The upper surface of the lower die 14 is provided with a groove 15 for placing the aluminum alloy. The side wall of the lower die 14 is fixedly connected to a transverse telescopic rod 9. The end of the telescopic rod 9 away from the lower die 14 is fixedly connected to a vertical limit plate 8. The limit plate 8 is used to form abutment against the aluminum alloy part to limit the movement of the aluminum alloy part. The lower surface of the lower die 14 is fixedly connected to a fixed plate 12. The fixed plate 12 is horizontally fixedly connected to the punching table 10 of the punch press. The fixed plate 12 is provided with an avoidance opening 13. The lower die 14 is provided with a die hole 16 used in conjunction with the punching column 6. The bottom end of the die hole 16 is connected to the avoidance opening 13. A waste box 11 is provided below the avoidance opening 13, and the top of the waste box 11 is open.

[0021] The specific implementation process is as follows:

[0022] When in use, the aluminum alloy part that needs to be punched is placed on the surface of the lower die 14, and then the punch press is started. When the punch press is started, the connecting plate 2 is driven downward by the downwardly moving stamping slider 1. When the connecting plate 2 moves downward, the movable plate 7 is driven downward by the two guide rods 4. The movable plate 7 moves downward until it contacts the aluminum alloy part and presses the aluminum alloy part so that it cannot move. While the stamping slider 1 moves downward, the stamping slider 1 drives the stamping plate 5 and the six stamping columns 6 to move downward through the connecting plate 2. When the stamping column 6 moves downward, it passes through the through hole 17 and punches the aluminum alloy part through the shear force, and the waste punched off the aluminum alloy part is pressed into the die hole 16 of the lower die 14 and falls from the avoidance opening 13. At this time, the punching of the aluminum alloy part is completed. When the movable plate 7 presses the aluminum alloy part, the connecting plate 2 continues to move downward, and the two guide rods 4 are inserted into the connecting plate 2. At the same time, the connecting plate 2 compresses the spring 3 to be in a compressed state. After the punching slide 1 of the punch press starts to move upward, the connecting plate 2 starts to move upward, and then drives the six punching columns 6 to move upward through the punching plate 5. At this time, the movable plate 7 still presses the aluminum alloy part under the elastic force of the spring 3, so the six punching columns 6 can be pulled out of the aluminum alloy part when moving upward.
