Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a stamping mold for cylindrical workpieces. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts (or semi-finished products), commonly known as cold stamping dies. They consist of an upper die and a lower die. During operation, the upper die moves downwards to cooperate with the lower die, applying pressure to the sheet metal, causing it to undergo plastic deformation or separation under the action of the die, thereby obtaining stamped parts of the desired shape and size. Stamping dies have advantages such as high production efficiency, high processing accuracy, and relatively low cost, and are widely used in many fields such as automotive, electronics, home appliances, and aerospace, making them an indispensable and important process equipment in modern manufacturing.

[0003] In punching cylindrical hardware parts, existing stamping dies mainly employ two methods: first, placing the workpiece upright and using a sliding mechanism to allow the punch to cut from the side; second, placing the workpiece horizontally and having the punch cut from top to bottom. Both methods have advantages and can meet the punching requirements for cylindrical workpieces. However, when multiple holes need to be punched continuously on a single workpiece, it's difficult to flexibly change the workpiece's position under the punch, impacting production efficiency.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical workpiece stamping die, including a base, a vertical plate provided on the base, a top seat provided on the vertical plate, and a punching assembly installed on the top seat;

[0007] The base is also provided with a mold base installed on one side of the upright plate. The mold base is provided with a clearance groove. A fixing post is provided on one side of the upright plate. The fixing post is provided with a material discharge hole, and the fixing post and the clearance groove are mutually accommodating.

[0008] The mold base has movable grooves on both sides that communicate with the clearance grooves. Movable blocks are movably arranged inside the movable grooves. An electromagnet is installed on the side of the movable block facing the fixed column. The electromagnet is used to attract the workpiece.

[0009] The movable groove is connected to the external space through the mold base on the side away from the fixed column, and a positioning plate is installed from the outside of the mold base into the movable groove. The positioning plate has uniformly arranged arc-shaped notches on the side facing the movable block. The movable block is provided with an arc-shaped block that abuts against the arc-shaped notches. A first elastic element is provided between the arc-shaped block and the movable block. The first elastic element can push the arc-shaped block to abut against the arc-shaped notches.

[0010] The upright plate is provided with a handle on the side away from the mold base. Guide rods are connected to both sides of the handle. The guide rods pass through the upright plate, extend into the movable groove, and are fixedly connected to the movable block.

[0011] As a further embodiment of this utility model: a second elastic element is provided between the electromagnet and the movable block, and the second elastic element is used to drive the electromagnet to move away from the fixed column.

[0012] As a further embodiment of this utility model: a magnetic conductor is connected to the side of the electromagnet facing the fixed column, and the magnetic conductor is arranged with an arc surface facing the side of the fixed column.

[0013] As a further embodiment of this utility model: the guide rod penetrates the mold base and protrudes into the external space.

[0014] As a further embodiment of this utility model: the positioning plate is provided with an installation plate on the side away from the movable block, and the installation plate is fixedly connected to the mold base by bolts.

[0015] As a further embodiment of this utility model: a material feeding groove is provided inside the fixing column, and the material feeding hole is connected to the material feeding groove;

[0016] The bottom surface of the material feeding trough is inclined from high to low towards the vertical plate, and the lowest point of the material feeding trough has an opening that connects with the clearance groove.

[0017] Both the mold base and the base are provided with a material feeding channel corresponding to the opening of the material feeding groove.

[0018] Compared with existing technologies, the beneficial effects of this technical solution are as follows: When multiple punching operations are required at different positions on the workpiece, the handle can be held and pushed or pulled. Two guide rods drive the movable block to move horizontally within the movable slot. At the same time, the electromagnet attracts the workpiece, allowing it to be moved during operation. When the arc-shaped block on the other side of the movable block is moved horizontally, the interaction force between the arc-shaped block and the arc-shaped notch causes the arc-shaped block to retract and squeeze the first elastic element, causing the arc-shaped block to move into the next arc-shaped notch. At this point, the first elastic element pushes the arc-shaped block to abut against the next arc-shaped notch. The operator then needs to apply force again to move the movable block, i.e., the electromagnet, the workpiece, and the arc-shaped block, thereby achieving the effect of positioning and adjusting the workpiece position for punching at different positions on the workpiece. The adjustment is convenient and helps to improve production efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 A cylindrical workpiece stamping die includes a base 1, a vertical plate 2 is provided on the base 1, a top seat 3 is provided on the vertical plate 2, and a punching assembly 4 is installed on the top seat 3.

[0031] The base 1 is also provided with a mold base 5 installed on one side of the upright plate 2. The mold base 5 is provided with a clearance groove 51. The upright plate 2 is provided with a fixing post 6. The fixing post 6 is provided with a material discharge hole 61, and the fixing post 6 and the clearance groove 51 are matched to allow for clearance.

[0032] The mold base 5 has movable grooves 52 on both sides that are connected to the clearance groove 51. Movable blocks 7 are movably arranged inside the movable grooves 52. Electromagnets 71 are installed on the side of the movable blocks 7 facing the fixed column 6. Electromagnets 71 are used to attract workpieces.

[0033] The side of the movable groove 52 away from the fixed column 6 protrudes from the mold base 5 and communicates with the external space. A positioning plate 8 is installed from the outside of the mold base 5 into the movable groove 52. The positioning plate 8 has evenly arranged arc-shaped notches 81 on the side facing the movable block 7. The movable block 7 is provided with an arc-shaped block 72 that abuts against the arc-shaped notches 81. A first elastic element 73 is provided between the arc-shaped block 72 and the movable block 7. The first elastic element 73 can push the arc-shaped block 72 to abut against the arc-shaped notches 81.

[0034] A handle 9 is provided on the side of the upright plate 2 away from the mold base 5. Guide rods 91 are connected to both sides of the handle 9. The guide rods 91 pass through the upright plate 2 and extend into the movable groove 52 and are fixedly connected to the movable block 7.

[0035] Specifically, the worker places the cylindrical workpiece onto the fixed post 6, covering the feeding hole 61. Then, the punching assembly 4 is activated to punch holes in the workpiece. When multiple punching operations are required at different locations, the handle is held and pushed forward or pulled backward. The two guide rods 91 drive the movable block 7 to move horizontally within the movable slot 52. Simultaneously, the electromagnets 71 installed on the movable block 7 are activated, using the electromagnets 71 on both sides to attract the workpiece, thus moving it during operation. The arc-shaped block 72 on the other side of the movable block 7 abuts against the arc-shaped notch 81 on the positioning plate 8, and the arc... Multiple notches 81 are evenly arranged. When the arc block 72 is moved, the interaction force between it and the arc notch 81 causes the arc block 72 to retract and squeeze the first elastic element 73, so that the arc block 72 moves into the next arc notch 81 and abuts against the next arc notch 81 through the push of the first elastic element 73. At this time, the operator needs to apply force again to drive the movable block 7, i.e., the electromagnet 71, the workpiece, and the arc block 72, thereby achieving the effect of positioning and adjusting the position of the workpiece, so as to punch holes at different positions of the workpiece. The adjustment is convenient and helps to improve production efficiency.

[0036] The upright plate 2 has a through hole for the guide rod 91 to pass through. The guide rod 91 extends through the through hole into the movable groove 52 and is fixed to the movable block 7. When the handle 9 is pushed or pulled, the guide rod 91 is guided and restricted by the through hole, which can ensure that the movable block 7 moves linearly.

[0037] The punching assembly 4 consists of a hydraulic cylinder (or pneumatic cylinder) and a punch. By activating the hydraulic cylinder, the punch is pushed to apply pressure to the workpiece, thereby achieving punching of the workpiece.

[0038] In this embodiment, reference Figure 5 and Figure 6 Furthermore, it is proposed that a second elastic element 74 is provided between the electromagnet 71 and the movable block 7, and the second elastic element 74 is used to drive the electromagnet 71 to move away from the fixed column 6.

[0039] Specifically, when the electromagnet 71 is not needed to attract the workpiece, its power can be turned off. At this time, the electromagnet 71 loses its magnetic attraction to the workpiece, and the second elastic element 74 moves the electromagnet 71 away from the workpiece to avoid the electromagnet 71 being too close to the fixed post 6, which would affect the loading of subsequent workpieces. When the electromagnet 71 needs to be used to attract the workpiece again, its power is turned on, and a magnetic attraction is generated between the electromagnet 71 and the workpiece, causing the workpiece to be fixed by the fixed post 6. This allows the electromagnet 71 to move toward and attract the workpiece. During this process, the electromagnet 71 will stretch the second elastic element 74. When the power of the electromagnet 71 is turned off again, the second elastic element 74 can move the electromagnet 71 away from the fixed post 6.

[0040] Both the first elastic element 73 and the second elastic element 74 are springs.

[0041] In this embodiment, reference Figure 5 Furthermore, it is proposed that a magnetic conductor 75 is connected to the side of the electromagnet 71 facing the fixed post 6, and the magnetic conductor 75 is arranged with an arc surface facing the fixed post 6. When the electromagnet 71 is activated, the magnetic attraction force generated by the electromagnet 71 will affect the magnetic conductor 75, so that the magnetic conductor 75 has a magnetic attraction force. Since the side of the magnetic conductor 75 is arranged with an arc surface, the magnetic conductor 75 can fit as close as possible to the workpiece, thereby increasing the adsorption area of ​​the workpiece and improving the stability when moving the workpiece.

[0042] In this embodiment, reference Figure 1 and Figure 3Furthermore, it is proposed that the guide rod 91 penetrates the mold base 5 and protrudes into the external space; the mold base 5 also has a through hole connected to the movable groove 52 on the side away from the vertical plate 2, and the guide rod 91 extends to the outside through the through hole. Combined with the guide rod 91 penetrating the vertical plate 2, both ends of the guide rod 91 are guided and restricted by the through hole, thereby improving the stability of the guide rod 91 when moving back and forth; wherein, after the end of the guide rod 91 extends to the outside of the mold base 5, a limiting plate can be set to prevent the guide rod 91 from disengaging from the through hole opened on the mold base 5.

[0043] In addition, refer to Figure 2 and Figure 5 Furthermore, it is proposed that the positioning plate 8 is provided with a mounting plate 82 on the side away from the movable block 7, and the mounting plate 82 is fixed to the mold base 5 by bolts.

[0044] Specifically, the mounting plate 82 of the positioning plate 8 is fixed to the mold base 5 by bolts, so that the operator can unscrew the bolts to remove the mounting plate 82 and the positioning plate 8 to replace the positioning plate 8 with arc-shaped notches 81 with different spacing, thereby changing the moving distance and improving production adaptability.

[0045] In this embodiment, reference Figure 4 Furthermore, it is proposed that the fixed column 6 has a material discharge groove 62 inside, and the material discharge hole 61 is connected to the material discharge groove 62;

[0046] The bottom surface of the material feeding trough 62 is inclined from high to low towards the vertical plate 2, and the lowest point of the material feeding trough 62 has an opening that connects with the clearance groove 51.

[0047] Both the mold base 5 and the base 1 are provided with a feeding channel 10 corresponding to the opening of the feeding groove 62.

[0048] Specifically, after the punching assembly 4 punches the workpiece, the scrap will fall into the feed trough 62 through the feed hole 61. Then, the scrap will slide down the inclined bottom surface of the feed trough 62 and fall into the feed channel 10 opened on the mold base 5 and the base 1 through the opening of the feed trough 62. Finally, it will fall to the bottom of the base 1. The bottom of the base 1 is provided with a scrap area gap, where the scrap accumulates and can be cleaned regularly by the staff.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
