Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die for aluminum alloy trim strips. Background Technology

[0002] Aluminum alloys have low density and high specific strength, and possess good mechanical properties, good corrosion resistance, excellent electrical and thermal conductivity, and good casting properties. Aluminum alloy trim strips are made of this material, and punching dies are required for processing aluminum alloy trim strips.

[0003] Existing punching dies require repositioning of the punching position for each aluminum alloy trim strip punching operation, which is cumbersome and unstable, leading to errors in the punching process. Furthermore, the clamping device requires frequent manual clamping and loosening adjustments, making it inconvenient to use. Therefore, we provide an aluminum alloy trim strip punching die to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects in the existing technology and provide a punching mold for aluminum alloy trim strips.

[0005] To achieve the above objectives, the technical solution of this utility model is to design an aluminum alloy trim punching mold, including a base plate, a lower template mounted on the upper end of the base plate, an upper template above the lower template, positioning posts mounted around the lower end of the upper template, an upper clamping plate movably inserted into the outer sides of the four sets of positioning posts, clamping grooves symmetrically arranged at the lower end of the upper clamping plate, a clamping mechanism mounted at the lower end of the upper clamping plate, punching heads symmetrically mounted at the lower end of the upper template, die holes symmetrically arranged at the lower end of the lower template corresponding to their positions, and through holes symmetrically arranged at the lower end of the base plate corresponding to their positions. The clamping mechanism includes three sets of spring rods connected to the upper clamping plate. A pushing assembly is installed at the lower end of the spring rods. Side clamping plates are installed on both sides of the pushing assembly. Side plates are symmetrically installed at the upper end of the lower template.

[0006] In a further preferred embodiment, the pushing assembly includes a support plate connected to a spring rod. The lower end of the support plate is symmetrically equipped with first connecting members. Each of the two first connecting members is rotatably connected to two sets of movable rods. Each of the four sets of movable rods is rotatably connected to a second connecting member. Each pair of second connecting members is connected to a side clamping plate.

[0007] In a further preferred embodiment, the lower end of each of the second connectors is connected to a limiting block, and the upper end of the lower template is provided with a limiting groove that slides with it.

[0008] In a further preferred embodiment, springs are connected to the lower perimeter of the upper clamping plate, and the lower ends of the springs are connected to the base plate. The springs are located outside the positioning posts, and positioning holes for insertion into the positioning posts are provided on the upper perimeter of the base plate.

[0009] In a further preferred embodiment, pads are symmetrically mounted on the lower end of the substrate.

[0010] The advantages and beneficial effects of this utility model are as follows: 1. By inserting the two trim pieces at the upper ends of the two aluminum alloy trim pieces into the two clamping grooves of the upper clamping plate, it is convenient to initially position the aluminum alloy trim pieces. Then, the aluminum alloy trim pieces are pushed towards one side of the clamping groove until the two trim pieces at the upper ends of the aluminum alloy trim pieces are in contact with one side of the clamping groove, which facilitates the positioning of the punching position of the aluminum alloy trim pieces, facilitates rapid positioning, and improves the positioning accuracy of the punching. 2. As the upper clamping plate moves down synchronously with the upper template, it drives the spring rod to move down, which in turn drives the support plate to move down. The first connecting piece at the lower end of the support plate drives one end of each of the two movable rods to move down, while the other end of each pair of movable rods drives the second connecting piece and the side clamping plate to move towards the aluminum alloy trim body. This continues until the side clamping plate pushes the aluminum alloy trim body to fit against the side plate, thereby clamping and fixing the aluminum alloy trim body. This effectively improves the automatic clamping and loosening effect, thus significantly increasing the efficiency of punching. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0014] Reference Figure 1-5 A punching die for aluminum alloy trim strips includes a base plate 1. A lower template 2 is mounted on the upper end of the base plate 1. An upper template 3 is positioned above the lower template 2. Positioning posts 4 are mounted around the lower end of the upper template 3. An upper clamping plate 5 is movably inserted into the outer side of the four sets of positioning posts 4. A clamping groove 13 is symmetrically arranged at the lower end of the upper clamping plate 5. A punching head 7 is symmetrically mounted at the lower end of the upper template 3. A die hole corresponding to the lower position is symmetrically arranged at the lower end of the lower template 2. A through hole corresponding to the lower position is symmetrically arranged at the lower end of the base plate 1. Springs 6 are connected around the lower end of the upper clamping plate 5. The lower ends of the springs 6 are all connected to the base plate 1. The springs 6 are located outside the positioning posts 4. Positioning holes 11 that are inserted into the positioning posts 4 are provided around the upper end of the base plate 1.

[0015] By placing one end of each of the two sets of aluminum alloy trim strips to be punched between the lower template 2 and the upper clamping plate 5, the two trim strips at the upper ends of the two aluminum alloy trim strips are respectively inserted into the inner cavities of the two clamping slots 13 of the upper clamping plate 5. This facilitates the initial positioning of the aluminum alloy trim strips. Then, the aluminum alloy trim strips are pushed towards one side of the inner cavity of the clamping slot 13 until the two trim strips at the upper ends of the aluminum alloy trim strips are in contact with one side of the inner cavity of the clamping slot 13. This facilitates the positioning of the aluminum alloy trim strips for punching, which is then convenient for the upper template 3 to be moved down by the hydraulic lifting mechanism (existing punching die drive equipment, which will not be described in detail again). The upper template 3 then moves the positioning pin 4 down through the hole. After the upper template 3 moves down and fits against the upper end of the upper clamping plate 5 through the positioning hole 11, it continues to move down and drives the upper clamping plate 5 to move down. When the upper clamping plate 5 moves down, the spring 6 is compressed. When the upper clamping plate 5 moves down, the top of the clamping groove 13 at the lower end of the upper clamping plate 5 gradually moves towards the two trim strips of the aluminum alloy trim strip body. Finally, the punching head 7 at the lower end of the upper template 3 cooperates with the die hole at the upper end of the lower template 2 to perform a punching operation on the aluminum alloy trim strip body. Then, the upper template 3 is reset by the hydraulic lifting mechanism. When the upper template moves away from the upper clamping plate 5, the compressed spring 6 rebounds and drives the upper clamping plate 5 to automatically reset, which makes it convenient to turn the two aluminum alloy trim strip bodies around and perform a punching operation on their other end.

[0016] A pad 9 is symmetrically mounted on the lower end of the substrate 1. When the punching head 7 performs punching operation, the waste chips that fall off the punching head fall from the die hole and through hole, so that the waste chips have space to fall and avoid having to manually remove the waste chips after each punching, which effectively improves the performance.

[0017] A clamping mechanism 8 is installed at the lower end of the upper clamping plate 5. The clamping mechanism 8 includes three sets of spring rods 81 connected to the upper clamping plate 5. A pushing assembly is installed at the lower end of the spring rods 81. Side clamping plates 86 are installed on both sides of the pushing assembly. Side plates 10 are symmetrically installed at the upper end of the lower template 2. The pushing assembly includes a support plate 82 connected to the spring rods 81. First connecting pieces 83 are symmetrically installed at the lower end of the support plate 82. Two sets of movable rods 84 are rotatably connected to the two first connecting pieces 83. Two sets of movable rods 84 are rotatably connected to the four sets of second connecting pieces 85. Each pair of second connecting pieces 85 is connected to one side clamping plate 86.

[0018] When the upper clamping plate 5 moves down synchronously with the upper template 3, the upper clamping plate 5 drives the spring rod 81 to move down, and the spring rod 81 drives the support plate 82 to move down synchronously. The first connecting piece 83 at the lower end of the support plate 82 drives one end of each of the two movable rods 84 to move down. The other end of each pair of movable rods 84 drives the second connecting piece 85 and the side clamping plate 86 to move towards the aluminum alloy trim body until the side clamping plate 86 is in contact with one end of the aluminum alloy trim body. Then, it continues to push the other end of the aluminum alloy trim body to be in contact with the side plate 10, thereby effectively clamping and fixing the aluminum alloy trim body. When the upper clamping plate 5 continues to move down with the upper template 3, the upper clamping plate 5 and the support plate 82 compress the spring rod 81, which can prevent the side plate 10 from continuing to push the aluminum alloy trim body and causing damage, thus effectively improving the clamping and fixing effect.

[0019] The lower end of the second connector 85 is connected to a limiting block 87, and the upper end of the lower template 2 is provided with a limiting groove 12 that slides with it. When the second connector 85 drives the side clamping plate 86 to move, the second connector 85 slides in the inner cavity of the limiting groove 12 through the limiting block 87, which effectively improves the stability of the side clamping plate 86.

[0020] Working principle: When punching the aluminum alloy trim body, the upper template 3 is connected to the external hydraulic lifting mechanism (existing punching die drive equipment, which will not be described in detail here). Then, one end of the two sets of aluminum alloy trim bodies to be punched is placed between the lower template 2 and the upper clamping plate 5, that is, the two trim pieces at the upper ends of the two aluminum alloy trim bodies are respectively inserted into the two clamping grooves 13 of the upper clamping plate 5, which facilitates the initial positioning of the aluminum alloy trim body. Then, the aluminum alloy trim body is continued to be pushed towards one side of the clamping groove 13 until the two trim pieces at the upper ends of the aluminum alloy trim body are in contact with the clamping groove 13. The inner cavity of groove 13 fits against each other, facilitating the positioning of the punching position of the aluminum alloy trim body. This allows the upper template 3 to be moved downwards via a hydraulic lifting mechanism, while the upper template 3 moves the positioning post 4 downwards through the positioning hole 11. After the upper template 3 moves downwards and fits against the upper end of the upper clamping plate 5, it continues to move downwards, causing the upper clamping plate 5 to move downwards as it moves downwards. When the upper clamping plate 5 moves downwards, the top of the clamping groove 13 at the lower end of the upper clamping plate 5 gradually moves towards the two trim bodies of the aluminum alloy trim body. At the same time, the upper clamping plate 5 moves the spring rod 81 downwards, and the spring rod 81 simultaneously moves the support plate 82 downwards. The lower end of the support plate 82... Each connector 83 drives one end of each of the two movable rods 84 to move downwards, while the other end of each pair of movable rods 84 drives the second connector 85 and the side clamping plate 86 to move towards the aluminum alloy trim body. This continues until the side clamping plate 86 is in contact with one end of the aluminum alloy trim body, then it continues to push the other end of the aluminum alloy trim body to be in contact with the side plate 10, thus effectively clamping and fixing the aluminum alloy trim body. Finally, when the punching head 7 at the lower end of the upper template 3 moves downwards to punch holes, that is, when the upper clamping plate 5 continues to move downwards with the upper template 3, the compression spring rod 81 between the upper clamping plate 5 and the support plate 82 prevents the side plate 10 from continuing to push against the aluminum alloy trim body. The damage to the trim strip body effectively improves the clamping and fixing effect. The punch head 7 cooperates with the die hole at the upper end of the lower template 2 to punch the aluminum alloy trim strip body. Then, the upper template 3 is reset by the hydraulic lifting mechanism. When the upper template moves away from the upper clamping plate 5, its compressed spring 6 rebounds and drives the upper clamping plate 5 to automatically reset. This makes it easy to turn the two aluminum alloy trim strip bodies around and punch the other end. This effectively improves the positioning accuracy of the punching and facilitates quick positioning and quick automatic clamping and releasing of the aluminum alloy trim strip body, effectively improving the punching efficiency.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
