Description

Technical Field

[0001] This utility model relates to the technical field of blanking die guide structure, and more specifically to a guide structure for blanking dies. Background Technology

[0002] A blanking die is a mold used to separate materials by stamping. It is mainly used to manufacture parts or blanks of various shapes and sizes. According to the nature of the process, blanking dies can be divided into blanking dies, punching dies, etc. According to the combination of processes, they can be divided into single-operation dies, compound dies, and progressive dies. The guiding structure of a blanking die is a positioning system used to ensure that the die maintains accurate and stable positioning during the stamping process. Guide pillars and guide sleeves are used together. The guide pillars are usually fixed on the lower die base, while the guide sleeves are installed on the upper die base. The guiding function is achieved through the cooperation between the two.

[0003] As shown in the prior art published in CN214023072U, although this prior art improves the guiding effect on the upper die by having a slider slide in a groove and a rod slide in a through hole, thereby improving the blanking effect of the upper die, and by setting rollers and balls to reduce the friction between the slider and the groove and between the rod and the through hole, reducing frictional wear on the slider and rod, thus making the upper die blanking more accurate, the prior art increases the manufacturing complexity of the slider and the overall structure when assembling rollers and balls, thereby increasing the cost. Furthermore, this technical solution does not allow for convenient disassembly and maintenance when rollers and balls wear out, making its practicality relatively low. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a guide structure for a punching die. Through the threaded connection between the bottom ring and the guide post and the bottom post, and the threaded connection between the top ring and the guide ring and the top post, the bottom ring and the bottom post can be easily separated or contacted, and the top ring and the top post can be easily separated or contacted. This achieves the effect of convenient disassembly and assembly of the guide post and the guide ring, thereby solving the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guide structure for a punching die, comprising a base plate, a lower die holder mounted on the top of the base plate, a top plate and an upper die holder mounted on the bottom of the top plate, and multiple sets of guide members for enhancing displacement stability provided between the top plate and the base plate.

[0006] Each set of guide components includes a guide post and a guide ring. The guide ring is sleeved on the outside of the top of the guide post. The top of the guide ring is threadedly connected to a top ring, and the top ring is threadedly connected to a top post. The top of the top post is fixed to the bottom of the top plate.

[0007] The bottom end of the guide post is externally threaded to a bottom ring, and the bottom ring is internally threaded to a bottom post, with the bottom end of the bottom post fixed to the top of the base plate.

[0008] In a preferred embodiment, a top sealing cylinder is sleeved on the bottom end of the top ring, and the sealing cylinder is fixedly sleeved on the outside of the guide ring.

[0009] In a preferred embodiment, a bottom sealing cylinder is fixedly sleeved on the outside of the bottom end of the guide post, and the bottom sealing cylinder is sleeved on the outside of the top end of the bottom ring.

[0010] In a preferred embodiment, two spaced-apart fixed plates are installed at the top of both ends of the base plate, a support plate is installed between the two fixed plates, and two spaced-apart telescopic rods are installed on the top of the support plate, with springs sleeved on the outer ends of the telescopic rods.

[0011] The top of the fixed plate is provided with the same contact plate, and the top of the telescopic rod is fixed together with the bottom of the contact plate.

[0012] In a preferred embodiment, a pressure plate is provided on the top of the contact plate, and the pressure plate is installed on the side of the bottom of the upper mold base near the contact plate.

[0013] In a preferred embodiment, a plurality of reinforcing plates are mounted on the top of the pressure plate, and the plurality of reinforcing plates are evenly spaced apart.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1.

Detailed Implementation

[0023] 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.

[0024] Refer to the instruction manual appendix Figure 1-5 This utility model provides a guide structure for a punching die, including a base plate 1, a lower die holder 2 installed on the top of the base plate 1, a top plate 3 and an upper die holder 4 installed at the bottom of the top plate 3, and multiple sets of guide members for enhancing displacement stability are provided between the top plate 3 and the base plate 1.

[0025] like Figure 1-5 As shown, each set of guide components includes a guide post 5 and a guide ring 6. The guide ring 6 is sleeved on the outside of the top end of the guide post 5. The top end of the guide ring 6 is threadedly connected to a top ring 7, and the top ring 7 is threadedly connected to a top post 8. The top end of the top post 8 is fixed to the bottom of the top plate 3. The bottom end of the guide post 5 is threadedly connected to a bottom ring 9, and the bottom ring 9 is threadedly connected to a bottom post 10. The bottom end of the bottom post 10 is fixed to the top of the bottom plate 1. Through the threaded connection between the bottom ring 9 and the guide post 5 and the bottom post 10, and the threaded connection between the top ring 7 and the guide ring 6 and the top post 8, the bottom ring 9 and the bottom post 10 can be easily separated or contacted, and the top ring 7 and the top post 8 can be easily separated or contacted, thereby achieving the effect of convenient assembly and disassembly of the guide post 5 and the guide ring 6.

[0026] In use, the guide ring 6 is fitted onto the guide post 5, and the guide ring 6 and the guide post 5 are placed between the top plate 3 and the bottom plate 1. Then, the bottom ring 9, which is threadedly connected to the guide post 5, is rotated to move down, so that the bottom ring 9 is threadedly fixed together with the bottom post 10. Then, the top ring 7, which is threadedly connected to the guide ring 6, is rotated to move up, so that the top ring 7 is threadedly fixed together with the top post 8. In this way, the guide ring 6 and the guide post 5 can be used for limiting and guiding, ensuring the displacement stability between the top plate 3 and the bottom plate 1, and ensuring the precise machining of the upper mold base 4 and the lower mold base 2.

[0027] When the guide post 5 and guide ring 6 are worn or even damaged, the operator rotates the bottom ring 9 to separate it from the bottom post 10 and fixes the bottom ring 9 to the bottom thread of the guide post 5. Then, the operator rotates the top ring 7 to separate it from the top post 8 and fixes the top ring 7 to the top thread of the guide ring 6. This achieves the effect of easy disassembly of the guide ring 6 and guide post 5 and avoids the difficulty of disassembly and assembly due to the complexity of the process.

[0028] To ensure the connection stability between the top ring 7 and the bottom ring 9, such as Figure 1-4 As shown, a top sealing cylinder 11 is sleeved on the bottom of the top ring 7, and the sealing cylinder is fixedly sleeved on the outside of the guide ring 6. The fixed sealing cylinder protects the threads between the guide ring 6 and the top ring 7, preventing impurities from adhering and affecting the connection between the top ring 7 and the guide ring 6. Since a bottom sealing cylinder 12 is fixedly sleeved on the bottom of the guide post 5, and the bottom sealing cylinder 12 is sleeved on the top of the bottom ring 9, the bottom sealing cylinder 12 can protect the threads between the bottom ring 9 and the guide post 5, thereby ensuring the connection stability between the top ring 7 and the bottom ring 9.

[0029] To mitigate the downward impact of the upper mold base 4, such as Figure 1 , 2As shown in Figure 5, two spaced-apart fixed plates 13 are installed at the top of both ends of the base plate 1. A support plate 14 is installed between the two fixed plates 13. Two spaced-apart telescopic rods 15 are installed on the top of the support plate 14. A spring 16 is sleeved on the top of the telescopic rod 15. A common contact plate 17 is provided at the top of the fixed plate 13. The top of the telescopic rod 15 is fixed to the bottom of the contact plate 17. A pressure plate 18 is provided on the top of the contact plate 17. The pressure plate 18 is installed on the bottom of the upper mold base 4 near the contact plate 17. The pressure plate 18 is supported by a spring 16. The elasticity of the spring 16 allows the contact plate 17 to be cushioned by the spring 16 when it comes into contact with the pressure plate 18, thus reducing the impact and preventing damage to the upper mold base 4 and lower mold base 2 caused by excessive downward impact. This ensures the integrity of the upper mold base 4 and lower mold base 2. Furthermore, since multiple reinforcing plates 19 are installed on the top of the pressure plate 18, and the multiple reinforcing plates 19 are evenly spaced, the pressure plate 18 can be supported and fixed from multiple directions by the multiple reinforcing plates 19. This ensures the stability of the pressure plate 18 and prevents the pressure plate 18 from tilting or collapsing.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
