Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a reinforced iron stamping die. Background Technology

[0002] In hinge connection systems such as car doors and furniture cabinet doors, hinge reinforcement is the core component that bears the load and ensures the long-term stable operation of the hinge. It needs to meet both high strength and high precision requirements. At present, the mass production of hinge reinforcement mainly relies on stamping process, which uses molds to complete the forming processes such as punching, flanging, and trimming of the sheet metal in sequence. This process has become the mainstream processing method in the industry due to its high production efficiency and low manufacturing cost.

[0003] Currently, the stamping process for hinges involves multiple steps, including punching, bending, and shaping. However, during the punching process, the waste material generated by the current stamping molds accumulates on the surface of the lower die base. Over time, this leads to a significant accumulation of waste material on the surface of the lower die base. If this waste material is not cleaned in time, it will affect the subsequent stamping process of the reinforcing iron, causing the stamped shape to be affected by the waste material.

[0004] Therefore, we propose a reinforced iron stamping die to solve the above problems. Utility Model Content

[0027] 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.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of this utility model provides a reinforced iron stamping die, including a lower die base 1, a lifting seat 2 distributed above the lower die base 1, the top center of the lifting seat 2 being connected to an external driving structure, and the driving principle is clear to those skilled in the art and will not be described in detail here, and an upper die base 3 fixed at the bottom center of the lifting seat 2. The upper surface of the lower die base 1 is provided with a structure for subsequent hinge reinforcing iron stamping, and correspondingly, the bottom of the upper die base 3 is provided with a stamping head and other structures for stamping, and the structure and distribution position are clear to those skilled in the art and will not be described in detail here.

[0030] A guide groove 4 is provided on one side of the top of the lower die base 1. The guide groove 4 is connected to the waste outlet 5 and is symmetrically distributed along the vertical center line of the lower die base 1. A waste outlet 5 is provided in the middle of the bottom end of the lower die base 1. A collection frame 6 is snapped into the bottom of the lower die base 1. A fixing rod 7 is fixedly provided on the inner side of the top of the lower die base 1, and a return spring 8 is sleeved on the outer surface of the middle section of the fixing rod 7. The fixing rod 7 and the lower die base 1 are detachably connected to facilitate the replacement of the return spring 8 in the future. A sliding sleeve 9 is fixedly connected to the other end of the return spring 8, and a push rod 10 is rotatably connected to the top of the sliding sleeve 9. A top plate 11 is rotatably connected to the other end of the push rod 10. There are two top plates 11, and both sides of the two top plates 11 are rotatably connected to the lower die base 1 through bearing seats. The plane formed by the two top plates 11 is slightly lower than the lowest position when stamping the hinge reinforcement.

[0031] In use, the hinge reinforcement iron to be stamped is placed on the stamping structure on the surface of the lower die base 1. Then, the lifting seat 2 moves longitudinally under the action of the external drive structure. As the lifting seat 2 moves longitudinally, the upper die base 3 fixed at the bottom center also moves accordingly. By using the stamping head and other structures at the bottom of the upper die base 3 in conjunction with the stamping structure on the surface of the lower die base 1, the hinge reinforcement iron can be stamped. During the stamping of the hinge reinforcement iron, the waste material generated by punching in some positions will fall onto the upper surface of the top plate 11. At this time, the two top plates 11 are in contact with each other and are distributed at a flat angle under the action of the punching structure. After the punching step of the hinge reinforcement iron is completed, the downward pressure applied to the top plate 11 disappears. At this time, when the top plate 11 is pressed down, it will push the sliding sleeve 9 through the push rod 10, causing it to move laterally along the fixed rod 7 and causing the return spring 8 to deform and generate a reverse force. Therefore, when the pressure disappears, the reverse force generated by the deformation of the return spring 8 will push the sliding sleeve 9 in the opposite direction, causing it to move laterally along the fixed rod 7. As the sliding sleeve 9 returns to its lateral position, it will push the push rod 10 connected to its top, thereby causing the push rod 10 to push the top plate 11 in the opposite direction, so that the top plate 11 and the lower die base 1 are inclined. Then, under the action of the inclination of the top plate 11, the waste material remaining on its surface will enter the guide groove 4 and flow in the guide groove 4. Finally, it will fall into the inner side of the collection frame 6 through the waste material outlet 5, which facilitates the subsequent centralized collection of waste material and prevents waste material from remaining on the surface of the lower die base 1, affecting the normal stamping process of the hinge reinforcing iron. It is worth noting that when the stamping support structure set on the surface of the lower die base 1 supports the hinge reinforcing iron, there is a certain gap between the position of the hinge reinforcing iron and the top plate 11, allowing the waste material to fall.

[0032] like Figure 4 and Figure 6As shown, in some embodiments, a guide rail 12 is provided on one side of the bottom of the lower mold base 1, and a clip 13 is fixed on one side of the top of the collection frame 6. The clip 13 is T-shaped in general, and the size of the clip 13 is adapted to the size of the guide rail 12.

[0033] When in use, since the size of the clip 13 is compatible with the size of the guide rail 12, when installing the collection box 6, simply insert the clip 13 into the guide rail 12 and let it slide along the guide rail 12 to install the collection box 6. Conversely, the collection box 6 can be disassembled.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, a guide groove 14 is provided on the upper surface of the lower mold base 1, a guide seat 15 is fixed at the top corner of the lower mold base 1, a guide rod 16 is provided on one side of the bottom of the upper mold base 3, the guide rods 16 are symmetrically distributed along the vertical center line of the upper mold base 3, and the positions of multiple guide rods 16 correspond one-to-one with the positions of the guide grooves 14, a vertical rod 17 is fixed at the bottom corner of the lifting seat 2, and a buffer sleeve 18 is sleeved on the bottom of the vertical rod 17, the vertical rod 17 is symmetrically distributed along the vertical center line of the lifting seat 2, the buffer sleeve 18 and the vertical rod 17 form a sliding connection, and the inner cavity of the buffer sleeve 18 is provided with a cavity for it to slide along the vertical rod 17, a buffer spring 19 is connected to the top of the buffer sleeve 18, and the two ends of the buffer spring 19 are respectively connected to the top of the buffer sleeve 18 and the bottom corner of the lifting seat 2, and the buffer sleeve 18 can be disassembled from the vertical rod 17 to facilitate the subsequent replacement of the buffer spring 19;

[0035] During use, as the lifting seat 2 moves longitudinally, the vertical rods 17 symmetrically arranged on both sides of its bottom also move longitudinally. At this time, the longitudinal movement of the vertical rods 17 pushes the buffer sleeve 18 to move accordingly, so that one end of the buffer sleeve 18 is input into the inner side of the guide seat 15. When the bottom of the buffer sleeve 18 contacts the bottom of the inner cavity of the guide seat 15, the buffer sleeve 18 will move along the vertical rod 17 and drive the buffer spring 19 to deform and generate a reverse force, thereby achieving the purpose of buffer protection. At the same time, as the lifting seat 2 moves, the upper mold seat 3 will drive the guide rod 16 to move accordingly and input one end of the guide rod 16 into the guide groove 14, thereby further achieving the purpose of guidance and preventing positional displacement during subsequent stamping of the hinge reinforcing iron.

[0036] like Figure 7 As shown, in some embodiments, the sliding sleeve 9 is slidably connected to the fixed rod 7 via the return spring 8, and the sliding sleeve 9 is symmetrically distributed along the vertical center line of the lower mold base 1.

[0037] When in use, when the sliding sleeve 9 moves laterally along the fixed rod 7, it will cause the return spring 8 to deform and generate a reverse force. Then, the reverse force generated by the deformation of the return spring 8 will be used to push the sliding sleeve 9 in the opposite direction, so as to realize the lateral reset of the sliding sleeve 9.

[0038] like Figure 7 As shown, in some embodiments, the two ends of the push rod 10 are rotatably connected to the sliding sleeve 9 and the top plate 11 respectively through connecting ears, and one end of the top plate 11 is rotatably connected to the lower mold base 1 through a bearing seat.

[0039] When in use, when the sliding sleeve 9 pushes the push rod 10, the push rod 10 will push the top plate 11, which is rotatably connected to its other end, so that one end of the top plate 11 rotates along one side of the top of the lower mold base 1.

[0040] In summary, the hinge reinforcement to be stamped is placed on the stamping structure on the surface of the lower die base 1. Then, the lifting seat 2 moves longitudinally, driving the upper die base 3 to move. The upper die base 3 is used to stamp the hinge reinforcement. During the stamping process, scrap falls onto the upper surface of the top plate 11. At this time, the two top plates 11 are in contact with each other and are distributed at a flat angle under the action of the punching structure. After the punching step of the hinge reinforcement is completed, the downward pressure applied to the top plate 11 disappears. When the top plate 11 is pressed down, it pushes the sliding sleeve 9 through the push rod 10, causing it to move laterally along the fixed rod 7 and causing the return spring 8 to deform accordingly. The reverse force is generated, so when the pressure disappears, the reverse force generated by the deformation of the return spring 8 will push the sliding sleeve 9 in the opposite direction, causing it to move laterally along the fixed rod 7. As the sliding sleeve 9 returns to its lateral position, it will push the push rod 10 connected to its top, thereby causing the push rod 10 to push the top plate 11 in the opposite direction, so that the top plate 11 and the lower mold base 1 are inclined. Then, under the action of the inclination of the top plate 11, the waste material remaining on its surface will enter the guide groove 4 and flow in the guide groove 4. Finally, it will fall into the inner side of the collection frame 6 through the waste outlet 5, which facilitates the subsequent centralized collection of waste material and prevents waste material from remaining on the surface of the lower mold base 1.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
