[0002] A stamping die is a special piece of equipment used in cold stamping to process materials into parts. Stamping is the process of applying pressure to material at room temperature using a die mounted on a press.

[0003] Existing high-speed stamping dies consist of an upper die and a lower die. During stamping, the upper die presses against the lower die at high speed. Guide pillars are provided between the upper and lower dies. Under the long-term stamping action of the upper die, the guide pillars wear out severely, resulting in a reduced service life of the stamping die. In view of this, this application proposes a stamping die with a lubrication structure. Utility Model Content

[0004] The main purpose of this invention is to provide a stamping die with a lubrication structure, which can improve the service life of the stamping die and reduce its wear.

[0005] To achieve the above objectives, this utility model proposes a stamping die with a lubrication structure, including a lower template. A lubrication assembly is provided inside the lower template. The lubrication assembly includes: an oil reservoir located inside the lower template, with an oil outlet hole on its interior surface and a through hole on its surface, through which an oil injection pipe is fixedly connected. A cap is threaded to the end of the oil injection pipe. Two sets of guide rods are symmetrically arranged, with both ends of the two sets fixedly connected to the inner wall of the oil reservoir. The guide rods penetrate and slidably connect to the side wall of a moving plate. A plug is fixedly connected to one side of the moving plate, and a return spring is fixedly connected to the other side of the moving plate. The end of the return spring away from the moving plate is fixedly connected to the inner wall of the oil reservoir.

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.

[0020] Please see Figures 1-3 This utility model provides a stamping die with a lubrication structure, including a lower template 1. Positioning holes 2 are provided at the four corners of the lower template 1. A sealing ring 3 is fixedly connected inside the positioning hole 2. A positioning rod 4 is inserted into the sealing ring 3. A protrusion 5 is fixedly connected to the side wall of the positioning rod 4. An upper template 6 is fixedly connected to the top of the positioning rod 4. There are four sets of positioning rods 4, and the four sets of positioning rods 4 are distributed at the corners of the bottom surface of the upper template 6. The positioning rods 4 are positioned by the positioning holes 2 and the sealing ring 3, which improves the stability of the upper template 6 during the stamping process. A lubrication component 7 is provided inside the lower template 1.

[0021] In this embodiment of the present invention, the lubrication component 7 includes:

[0022] An oil storage tank 71 is located inside the lower template 1. An oil outlet hole 72 is provided inside the oil storage tank 71. A through hole is provided on the surface of the oil storage tank 71, and an oil injection pipe 73 is fixedly connected in the through hole. A cap 74 is threaded to the end of the oil injection pipe 73. The oil storage tank 71 is filled with lubricating oil. By opening the cap 74, lubricating oil can be easily injected into the oil injection pipe 73, thereby storing the lubricating oil through the oil storage tank 71 and allowing the lubricating oil to flow out through the oil outlet hole 72.

[0023] And guide rods 75, two sets of guide rods 75 are symmetrically arranged, and the two ends of the two sets of guide rods 75 are fixedly connected to the inner wall of the oil storage tank 71. The guide rods 75 pass through and are slidably connected to the side wall of the moving plate 76. A plug 77 is fixedly connected to one side of the moving plate 76, and a return spring 78 is fixedly connected to the other side of the moving plate 76. The end of the return spring 78 away from the moving plate 76 is fixedly connected to the inner wall of the oil storage tank 71. The moving plate 76 is guided by the two sets of guide rods 75, and the moving plate 76 is tightly fitted to the side wall of the oil storage tank 71 under the elastic force of the return spring 78, thereby sealing the oil outlet 72, thus preventing all the lubricating oil from flowing out at once. At the same time, the plug 77 is inserted into the inside of the oil outlet 72 and a part of it is exposed outside the oil outlet 72.

[0024] In this embodiment of the utility model, the lubrication assembly 7 includes an oil reservoir 71, an oil outlet 72, an oil injection pipe 73, a cap 74, a guide rod 75, a moving plate 76, a plug 77, and a return spring 78. The diameter of the plug 77 is smaller than the diameter of the oil outlet 72. During stamping, the upper template 6 drives the positioning rod 4 to move downward, causing the protrusion 5 to press against the end of the plug 77. This causes the moving plate 76 to press against the return spring 78, compressing the return spring 78. The moving plate 76 then separates from the inner wall of the oil reservoir 71, opening the oil outlet 72 and dripping lubricating oil into the positioning hole 2, thereby lubricating the positioning rod 4.

[0025] In addition, in order to reduce the service life of the stamping die, the upper template 6 drives the positioning rod 4 to move downward, so that the protrusion 5 squeezes the end of the plug 77, the return spring 78 is compressed, the moving plate 76 separates from the inner wall of the oil reservoir 71, thereby opening the oil outlet 72 and dripping lubricating oil into the positioning hole 2, thereby lubricating the positioning rod 4.

[0026] To reduce lubricating oil waste, the moving plate 76 is guided by two sets of guide rods 75, and the moving plate 76 is tightly fitted to the side wall of the oil reservoir 71 under the elastic force of the return spring 78, thereby blocking the oil outlet 72 and preventing all the lubricating oil from flowing out at once.

[0027] In this invention, during use, by opening the cap 74, lubricating oil can be easily injected into the oil injection pipe 73, thereby storing the lubricating oil in the oil storage tank 71. The moving plate 76 is guided by two sets of guide rods 75, and under the elastic force of the return spring 78, the moving plate 76 is tightly fitted to the side wall of the oil storage tank 71, thereby sealing the oil outlet 72. During stamping, the upper template 6 drives the positioning rod 4 to move downward, causing the protrusion 5 to squeeze the end of the plug 77, thereby pressurizing the return spring 78 on the moving plate 76. The return spring 78 is compressed, and the moving plate 76 separates from the inner wall of the oil storage tank 71, thereby opening the oil outlet 72 and dripping lubricating oil into the positioning hole 2, thereby lubricating the positioning rod 4.
