Description

Technical Field

[0001] This application relates to molds, and more particularly to a chamfer structure at the end of a progressive die for parts. Background Technology

[0002] Progressive dies are a common type of die used in stamping processes. They consist of multiple stations arranged sequentially along the feeding direction, mounted on the same die set. During operation, the strip material is fed intermittently at a set pitch, and each station performs different stamping operations in sequence, such as punching, blanking, and bending, ultimately producing finished or semi-finished products. Progressive dies offer numerous advantages: high production efficiency, completing multiple processes in a single stamping stroke; high precision, with accurate relative positioning of the processed parts at each station; safe and convenient operation, facilitating the use of automatic feeding equipment; and long die life. They are suitable for manufacturing parts in industries such as electronics, automotive, and consumer hardware, and are of great significance for mass production.

[0003] After the existing progressive die stamping, there will be burrs on the edge of the parts. In particular, the end of the parts is usually collected directly after stamping and requires further chamfering by the staff. However, chamfering multiple parts separately is time-consuming and laborious, and the staff are easily scratched by the burrs when handling the parts. Utility Model Content

[0004] To address the difficulty of chamfering the ends of components, this application provides a chamfering structure for the ends of continuous molds for components.

[0005] The chamfering structure at the end of a progressive die for a component provided in this application adopts the following technical solution:

[0006] A chamfering structure for the end of a continuous die for a component includes a base plate and a stamping machine for stamping the component, with a worktable fixedly mounted on the top of the base plate. The stamping machine includes a stamping base fixedly connected to the top of the worktable, a stamping top plate mounted on the stamping base, and a stamping die mounted on the bottom of the stamping top plate. A stamping groove is formed on the surface of the stamping base for the stamping die to pass through. A chamfering die for chamfering the end of the component is mounted on the worktable. A transport mechanism for transporting the component is mounted on the top of the base plate, and a collection mechanism for collecting the component is mounted on the base plate.

[0007] The chamfering mold includes a lower mold fixedly connected to the top of the workbench, and an upper mold fixedly connected to the bottom of the stamping top plate is provided above the lower mold. Both the upper mold and the lower mold have chamfering grooves on their adjacent sides that abut against the end of the part.

[0008] The transport mechanism includes a slide table set on the upper surface of the base plate. A cylinder is fixedly installed at the movable end of the slide table to support a support plate 1. A cylinder is fixedly installed at the movable end of the slide table to support a support plate 2. Limiting grooves for placing parts are opened on the upper surfaces of both the support plate 1 and the support plate 2. A support column fixedly connected to a support block is fixedly installed on the top of the base plate. A slot for placing the front end of a part is opened on the top of the support block.

[0009] By adopting the above technical solution, the end of the continuous mold of the parts can be chamfered by setting a chamfering mold. The chamfering mold can chamfer the end of two parts at the same time, which improves work efficiency and makes the edge of the part end smooth, effectively avoiding scratching the staff during transportation and storage, and ensuring the personal safety of the staff. The chamfered parts can be collected by the transportation mechanism and the collection mechanism for the staff to handle.

[0010] Preferably, the end of the component has the same shape and size as the chamfered groove.

[0011] By adopting the above technical solution, the chamfered groove side rounded corner structure can effectively chamfer the ends of parts.

[0012] Preferably, the bottom surface of the upper mold abuts against the top surface of the lower mold.

[0013] By adopting the above technical solution, the bottom surface of the upper mold and the top surface of the lower mold abut against each other, so that the upper and lower molds can simultaneously be chamfer the upper and lower end faces of the parts under the pressure of the stamping machine.

[0014] Preferably, the middle part of the component abuts against the inner side of the limiting groove.

[0015] By employing the above technology, the middle part of the component abuts against the inner side of the limiting groove, enabling the limiting groove to provide a limiting function for the component.

[0016] Preferably, a limiting rod is fixedly provided in the middle of both the first support plate and the second support plate, and the upper end of the limiting rod extends through the middle of the component to the top of the component.

[0017] By adopting the above technical solution, the limiting rod penetrates the component, thereby further enhancing the limiting effect of the limiting rod on the component.

[0018] Preferably, the maximum distance that the movable end of the slide can move is the distance between cylinder one and cylinder two.

[0019] By adopting the above technical solution, the moving end of the slide table moves cylinder one to the original position of cylinder two.

[0020] Preferably, the maximum height to which the first cylinder output end moves the first support plate is higher than the height of the support block, and the maximum height to which the second cylinder output end moves the second support plate is higher than the height of the steel wire.

[0021] By adopting the above technical solution, the output end of cylinder one moves upward so that the component on support plate one can be higher than the support block, so that when cylinder one descends, the front end and the end end of the component can be placed into the chamfered groove and the slot respectively. The output end of cylinder two moves upward so that the component on support plate two can be higher than the steel wire, so that when the output end of cylinder two descends, the component can be guided by the steel wire to fall into the collecting slide rail.

[0022] Preferably, the collecting mechanism includes a support frame fixedly connected to the top of the base plate, a collecting slide rail for collecting fallen parts is fixedly provided on the inner side of the support frame, and a steel wire for guiding the falling parts is fixedly provided on one side of the collecting slide rail.

[0023] By adopting the above technical solution, the steel wire can guide the chamfered parts on the second support plate to be unloaded, thereby preventing the parts from accumulating on the second support plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] By setting up a chamfering mold, the ends of continuous molds for parts can be chamfered. The chamfering mold can chamfer the ends of two parts at the same time, which improves work efficiency and makes the edge of the part end smooth, effectively preventing scratches to workers during transportation and storage, and ensuring the personal safety of workers. The chamfered parts can be collected by the transportation mechanism and the collection mechanism for workers to handle. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0040] Example 1

[0041] This application discloses a chamfer structure at the end of a continuous die for a component.

[0042] Reference Figure 1 , Figure 2 and Figure 7 A chamfering structure at the end of a continuous die for a component includes a base plate 1 and a stamping machine 2 mounted above the base plate 1 for stamping the component 6. The stamping machine 2 includes a stamping base 23 fixedly connected to the top of a worktable 11. The top of the base plate 1 is fixedly connected to the bottom of the worktable 11. A stamping top plate 21 is located above the worktable 11, and the size of the stamping top plate 21 is the same as that of the worktable 11. Both the bottom surface of the stamping top plate 21 and the top surface of the worktable 11 have multiple threaded holes for easy connection with screws, allowing the stamping machine 2 to... The stamping range can cover the surface of the workbench 11. The surface of the stamping base 23 is provided with a stamping groove 24. The inner side of the stamping groove 24 is movably connected to the side of the stamping die 22. The top of the stamping die 22 is fixedly connected to the bottom of the stamping top plate 21. The workbench 11 is provided with a scrap trough 13 with the same shape and size as the stamping groove 24 at the position of the stamping groove 24. The bottom plate 1 is provided with a collection trough 12 below the scrap trough 13, so that the scrap after the end of the part 6 is stamped can fall into the collection trough 12 and be collected.

[0043] When in use, the stamping press 2 is turned on to stamp the end of the part 6. The stamping top plate 21 moves downward, and at the same time, the stamping die 22 moves gradually through the stamping groove 24 of the stamping base 23, further stamping the end of the part 6 of the progressive die. The stamping die 22 moves downward, causing the divided waste material to pass through the stamping groove 24 and the waste material groove 13 and fall into the collection groove 12.

[0044] Reference Figure 3 , Figure 6 and Figure 7 The chamfering die 3 includes a lower die 32 fixedly connected to the top of the worktable 11, and an upper die 31 set directly above the lower die 32. Both the upper die 31 and the lower die 32 have several mounting holes 33 on their surfaces. The top of the upper die 31 is fixedly connected to the bottom of the stamping top plate 21. Both the upper die 31 and the lower die 32 have symmetrically distributed chamfering grooves 34 on their sides. The inner side of the chamfering groove 34 abuts against the end of the part 6, which can chamfer the ends of two parts 6 at the same time. The shape and size of the chamfering groove 34 are consistent with the shape and size of the end of the part 6. The side wall of the chamfering groove 34 is a rounded corner structure with a certain curvature, which makes the end of the part 6 more rounded after chamfering. The side of the upper die 31 near the lower die 32 abuts against the side of the lower die 32 near the upper die 31, so that the chamfering die 3 can perform a good chamfering treatment on the end of the part 6 under the pressure provided by the stamping machine 2.

[0045] During installation, first install the upper mold 31 onto the stamping top plate 21, and fix it by passing screws through the mounting holes 33 of the upper mold 31 and the threaded holes of the stamping top plate 21. Then, install the lower mold 32 onto the worktable 11 directly below the upper mold 31, so that the chamfered groove 34 of the upper mold 31 corresponds to the chamfered groove 34 of the lower mold 32. Finally, fix it by passing screws through the mounting holes 33 of the lower mold 32 and the threaded holes of the worktable 11.

[0046] The slide table 41 includes a fixed end, a movable end, a slider, a guide rail, and a telescopic cylinder. The slide table 41 is a mature existing technology product, and its detailed structural principle will not be described in detail here.

[0047] Reference Figures 4-5The transport mechanism 4 includes a slide 41 mounted on the top of the base plate 1. Two cylinders 42 are symmetrically fixedly arranged on the upper surface of the movable end of the slide 41. The top of the output end of cylinder 42 is fixedly connected to the bottom of support plate 44, allowing the output end of cylinder 42 to control the movement of support plate 44. Two cylinders 43 are symmetrically fixedly arranged on the upper surface of the movable end of the slide 41. The top of the output end of cylinder 43 is fixedly connected to the bottom of support plate 45, allowing the output end of cylinder 43 to control the movement of support plate 45. Limiting grooves 46 of the same shape and size are formed on the top of both support plate 44 and support plate 45. The inner side of the limiting groove 46 is connected to the zero... The bottom of component 6 abuts against the middle to provide a limiting effect on component 6. The bottom of the inner side of the limiting groove 46 is fixedly connected to the bottom end of the limiting rod 47. The surface of the limiting rod 47 is movably connected to the circular groove in the middle of component 6. The upper end of the limiting rod 47 is set as a pointed tip so as to pass through the circular groove in the middle of component 6. The limiting rod 47 further provides a limiting effect on component 6 to prevent component 6 from falling off. Two symmetrical support columns 48 are fixedly installed on the top of the base plate 1 on both sides of the slide table 41. The top of the support column 48 is fixedly connected to the bottom of the support block 49. The top of the support block 49 is provided with a slot 410, which engages with the front end of component 6.

[0048] In use, cylinder 42 is activated, and its output end moves upward, simultaneously driving support plate 44 and limit rod 47 upward. This causes the limit groove 46 of support plate 44 to abut against the bottom of part 6, and the limit rod 47 to pass through the circular groove of part 6. After the stamping press 2 completes the stamping of the end of part 6, the end of part 6 separates from the continuous die. The stamping top plate 21 moves upward to prepare for the next stamping without hindering the subsequent movement of cylinder 42. The slide table 41 is activated, and its movable end drives cylinder 42 towards cylinder 43. The output end of cylinder 42 continues to move upward, further causing the un-chamfered part 6 to move upward with support plate 44. Meanwhile, the chamfered part 6 moves upward with the support plate 45, making the height of the unchamfered part 6 higher than the support block 49, and the chamfered part 6 higher than the steel wire 52. At this time, the horizontal position of cylinder 42 is the same as that of cylinder 43 before the moving end of the slide table 41 moves. Cylinder 43 is located below the steel wire 52. Then, the output ends of cylinder 42 and cylinder 43 are controlled to descend, so that the unchamfered part 6 is supported by the lower mold 32 and the support block 49. The front end of the unchamfered part 6 is inserted into the slot 410 and the end is in the chamfering slot 34. The chamfered part 6 is guided down by the steel wire 52 and further collected. Then the slide table 41 returns to its original position and the process is repeated.

[0049] Reference Figures 3-5The collection mechanism 5 includes a support frame 51 fixedly connected to the top of the base plate 1. The side of the support frame 51 near the collection slide rail 53 is fixedly connected to the side of the collection slide rail 53 near the support frame 51, so that the end of the two collection slide rails 53 that is close to each other is higher than the end that is far away, so that the parts 6 can slide in the collection slide rail 53. The bottom end of the steel wire 52 is fixedly connected to the side of the collection slide rail 53 near the worktable 11, and a collection frame is placed below the end of the collection slide rail 53 to collect the parts 6 that have slid down.

[0050] During installation, first fix the support frame 51 to the base plate 1, adjust the position of the two collection slide rails 53 so that the end of the two collection slide rails 53 that is close to each other is higher than the end that is far away, fix and weld the collection slide rails 53 to the support frame 51, then weld the ends of the two collection slide rails 53 that are close to each other together to enhance the stability of the structure, and finally weld the steel wire 52 to the side of the collection slide rail 53 that is close to the worktable 11.

[0051] The implementation principle of the chamfer structure at the end of a continuous die for a component in this application embodiment is as follows:

[0052] After the end of component 6 is stamped, the horizontal movement of slide 41 and the lifting and lowering of cylinder 42 are controlled to move component 6, whose end has not been chamfered, on support plate 44 to chamfer groove 34. Then, the chamfered component 6 is moved above steel wire 52 by support plate 45 and guided by steel wire 52 to fall into collection rail 53. It then slides down collection rail 53 and is collected into collection frame.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
