Description

Technical Field

[0001] This utility model relates to the field of bidirectional punching die equipment, specifically to a bidirectional punching die for magnesium-aluminum alloy die castings. Background Technology

[0002] The main function of bidirectional punching dies for magnesium-aluminum alloy die castings is to achieve efficient punching of magnesium-aluminum alloy die castings.

[0003] The mold design allows for simultaneous upper and lower die-cutting of magnesium-aluminum alloy die-cast parts, avoiding the cumbersome process of creating two sets of molds or relying on two processes for die-cutting. This design not only improves die-cutting efficiency but also reduces mold costs and worker workload, thereby significantly increasing production efficiency. Through precise die-cutting operations, the mold ensures the dimensional accuracy and surface quality of magnesium-aluminum alloy die-cast parts, meeting the high standards required for product manufacturing. However, during the die-cutting process, with both upper and lower molds cutting simultaneously, and during the placement and removal of the die-cast parts, workers' hands are easily caught between the upper and lower molds, posing a mechanical injury and safety hazard. Utility Model Content

[0004] In response to the technical problem that the operator's hands are easily caught between the upper and lower dies during the current punching process, causing mechanical injury and posing a safety hazard, this utility model provides a bidirectional punching die for magnesium-aluminum alloy die castings.

[0005] The technical solution adopted by this utility model is as follows: It includes a processing table, on which a support column is fixedly connected, and a connecting plate is fixedly installed on the support column. A first hydraulic cylinder is fixedly installed on the processing table, and a first mounting plate is fixedly connected to the piston rod end of the first hydraulic cylinder. A lower die is fixedly installed on the first mounting plate. A second hydraulic cylinder is fixedly installed below the connecting plate, and a second mounting plate is fixedly connected to the piston rod end of the second hydraulic cylinder. An upper punch is fixedly installed below the second mounting plate, and the upper punch and lower die are adapted to each other. Sliding grooves are provided on both the processing table and the connecting plate, and limit rods are slidably connected in the sliding grooves. A driving mechanism is provided on the processing table.

[0006] Furthermore, the drive mechanism includes a mounting groove formed in the processing table and the connecting plate, a slide block slidably mounted in the mounting groove, and a lead screw rotatably mounted in the mounting groove. A drive motor is fixedly mounted at one end of the processing table, and the drive shaft of the drive motor is fixedly coaxially connected to one end of the lead screw. The slide block and the lead screw are threadedly connected, and the limiting rod is fixedly connected to the slide block.

[0007] By adopting the above technical solution, the driving limit rod moves in the slide groove.

[0008] Furthermore, a first bevel gear is fixedly installed at one end of each of the two sets of lead screws, and a rotating rod is rotatably installed in the support column. A second bevel gear is fixedly connected to both ends of the rotating rod, and the second bevel gear meshes with the first bevel gear.

[0009] By adopting the above technical solution, the drive motor can simultaneously drive two sets of lead screws to rotate.

[0010] Furthermore, each of the mounting grooves has a limiting groove on its side wall, and a limiting block is slidably connected in the limiting groove. The limiting block is fixedly connected to the side of the slide block.

[0011] By adopting the above technical solution, the stability of the slide during movement is improved.

[0012] Furthermore, a guide rail is provided on one side of the support column, and guide blocks are fixedly connected to one side of both the first mounting plate and the second mounting plate, with the guide blocks slidably installed in the guide rail.

[0013] By adopting the above technical solution, the stability of the upper punch and lower die during movement is improved.

[0014] Furthermore, a guide post is fixedly installed below the upper punch, and guide holes are provided on both the first mounting plate and the lower die, with the guide holes being adapted to the guide post.

[0015] By adopting the above technical solution, the accuracy of the upper punch and lower die docking is improved.

[0016] Furthermore, the first mounting plate and the lower die are provided with through holes, and a push rod is slidably installed in the through holes, and the push rod is fixedly installed on the processing table.

[0017] By adopting the above technical solution, it is easier to handle the magnesium-aluminum alloy die-cast parts after punching and cutting.

[0018] The beneficial effects of this utility model are: by using a processing table in conjunction with a connecting plate, a drive motor, a lead screw, a slide block, and a limiting rod, two sets of limiting rods limit the positions of the upper punch and the lower die before placing and picking up magnesium-aluminum alloy die castings, thus preventing workers from getting their hands pinched during operation, thereby avoiding mechanical injuries and eliminating corresponding safety hazards.

[0019] By using a sliding block with a limiting groove and a limiting block, the stability of the sliding block and the limiting rod during movement is improved. The first mounting plate and the second mounting plate, together with the guide rail and the guide block, improve the stability of the lower die and the upper punch during the punching process, and improve the quality of the magnesium-aluminum alloy die castings after punching.

[0020] With the help of the machining table, the ejector rod, and the through holes opened on the first mounting plate and the lower die, after the punching is completed, the first hydraulic cylinder drives the first mounting plate and the lower die to move downwards. The upper end of the ejector rod is inserted into the through hole, and the punched magnesium-aluminum alloy die casting is ejected from the lower die, making it easier for the operator to take it out and improving the convenience of using the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below.

[0031] To address the problems existing in the background art, this application proposes the following technical solution: A processing table 1 is included, a support column 2 is fixedly connected to the processing table 1, a connecting plate 3 is fixedly installed on the support column 2, a first hydraulic cylinder 4 is fixedly installed on the processing table 1, a first mounting plate 5 is fixedly connected to the piston rod end of the first hydraulic cylinder 4, a lower die 6 is fixedly installed on the first mounting plate 5, a second hydraulic cylinder 7 is fixedly installed below the connecting plate 3, a second mounting plate 8 is fixedly connected to the piston rod end of the second hydraulic cylinder 7, an upper punch 9 is fixedly installed below the second mounting plate 8, the upper punch 9 and the lower die 6 are adapted to each other, a sliding groove 10 is provided on both the processing table 1 and the connecting plate 3, a limit rod 11 is slidably connected in the sliding groove 10, and a driving mechanism is provided on the processing table 1.

[0032] The magnesium-aluminum alloy die-cast part is placed on the lower die 6. Simultaneously, the first hydraulic cylinder 4 and the second hydraulic cylinder 7 are activated. The two sets of piston rods drive the lower die 6 and the upper punch 9 closer together. The lower die 6 and the upper punch 9 cooperate to perform a punching operation on the magnesium-aluminum alloy die-cast part. Before placing and removing the die-cast part, the limiting rod 11 is moved to one side of the lower die 6 and the upper punch 9. The limiting rod 11 is L-shaped, and one end of each of the two sets of limiting rods 11 restricts the lower die 6 and the upper punch 9 respectively (as shown in the attached diagram). Figure 1 As shown), the movement of the lower die 6 and the upper punch 9 is restricted to prevent the lower die 6 and the upper punch 9 from being automatically activated due to electrical faults in the first hydraulic cylinder 4 and the second hydraulic cylinder 7, thus avoiding mechanical injury and eliminating the corresponding safety hazards. The limit rod 11 is driven to move in the slide groove 10 through the drive mechanism.

[0033] To further explain, the drive mechanism includes a mounting groove 12 formed in the processing table 1 and the connecting plate 3, a slide block 13 slidably mounted in the mounting groove 12, and a lead screw 14 rotatably mounted in the mounting groove 12. A drive motor 15 is fixedly mounted at one end of the processing table 1. The drive shaft of the drive motor 15 is fixedly coaxially connected to one end of the lead screw 14. The slide block 13 is threadedly connected to the lead screw 14. A limit rod 11 is fixedly connected to the slide block 13.

[0034] The drive motor 15 drives the lead screw 14 to rotate, the lead screw 14 pushes the slide block 13 to move, and the slide block 13 drives the limiting rod 11 to move. Adjusting the position of the limiting rod 11 in the slide groove 10, the limiting rod 11 is moved to one side of the lower die 6 and the upper punch 9 when placing and removing the die casting. During the punching operation, the limiting rod 11 is first moved to one side of the slide groove 10 and then moved away from one side of the lower die 6 and the upper punch 9 (as shown in the attached diagram). Figure 6 (As shown), to avoid the limit rod 11 from obstructing the punching operation.

[0035] To further explain, a first bevel gear 16 is fixedly installed at one end of each of the two sets of lead screws 14, and a rotating rod 17 is rotatably installed in the support column 2. A second bevel gear 18 is fixedly connected to both ends of the rotating rod 17, and the second bevel gear 18 meshes with the first bevel gear 16.

[0036] When the drive motor 15 drives a set of lead screws 14 to rotate, the lead screws 14 drive a set of first bevel gears 16 to rotate. The first bevel gears 16 drive the rotating rod 17 to rotate through the second bevel gear 18. The rotating rod 17 drives the other set of lead screws 14 to rotate through another set of second bevel gears 18 and first bevel gears 16. This allows the drive motor 15 to drive both sets of lead screws 14 to rotate simultaneously, reducing the cost of the device and making it more economical.

[0037] Furthermore, each side wall of the mounting groove 12 is provided with a limiting groove 19, and a limiting block 20 is slidably connected in the limiting groove 19. The limiting block 20 is fixedly connected to the side of the slide block 13.

[0038] The limiting block 20, together with the limiting groove 19, guides and limits the movement of the slide block 13, preventing the slide block 13 from flipping over when the lead screw 14 rotates, and improving the stability of the slide block 13 and the limiting rod 11 during movement.

[0039] Furthermore, a guide rail 21 is provided on one side of the support column 2, and guide blocks 22 are fixedly connected to one side of both the first mounting plate 5 and the second mounting plate 8. The guide blocks 22 are slidably installed in the guide rail 21.

[0040] The guide block 22, together with the guide rail 21, guides the movement of the first mounting plate 5 and the second mounting plate 8, improving the stability of the movement of the lower die 6 and the upper punch 9 during the punching process, which is beneficial to improving the quality of the magnesium-aluminum alloy die castings after punching.

[0041] Furthermore, a guide post 23 is fixedly installed below the upper punch 9, and guide holes 24 are provided on both the first mounting plate 5 and the lower die 6. The guide holes 24 are adapted to the guide post 23.

[0042] During the punching process, the guide post 23 is first inserted into the guide hole 24 to ensure that the lower die 6 and the upper punch 9 are precisely aligned, thereby improving the punching quality of the magnesium-aluminum alloy die casting.

[0043] Furthermore, the first mounting plate 5 and the lower die 6 are provided with through holes 25, and a push rod 26 is slidably installed in the through hole 25. The push rod 26 is fixedly installed on the processing table 1.

[0044] After the punching is completed, the first hydraulic cylinder 4 drives the first mounting plate 5 and the lower die 6 to move downwards, and the upper end of the push rod 26 is inserted into the through hole 25 to push the punched magnesium-aluminum alloy die casting out of the lower die 6, making it easier for the operator to take it out and improving the convenience of using the device.

[0045] For specific operation, please refer to the following steps: Before placing the magnesium-aluminum alloy die casting on the lower die 6, start the drive motor 15. The drive motor 15 drives the lead screw 14 to rotate, the lead screw 14 pushes the slide block 13 to move, and the slide block 13 drives the limit rod 11 to move. Move the limit rod 11 to one side of the lower die 6. The lead screw 14, in conjunction with the first bevel gear 16, the rotating rod 17, and the second bevel gear 18, rotates to drive another set of lead screws 14 to rotate, so that the other set of limit rods 11 moves to one side of the upper punch 9. Place the magnesium-aluminum alloy die casting on the lower die 6, and move the two sets of limit rods 11 away from one side of the lower die 6 and the upper punch 9. At the same time, start the first hydraulic cylinder 4 and the second hydraulic cylinder 7. The two sets of piston rods drive the lower die 6 and the upper punch 9 to move closer to each other. The lower die 6 and the upper punch 9 cooperate to perform punching operations on the magnesium-aluminum alloy die casting.
