DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0023] Refer to Figures 1-6The utility model provides a punch die with high -efficient power guide mechanism, including lower die seat 001, the lower die seat 001 upper end fixedly connected with a plurality of bottom column 101, and a plurality of directional slot 102 are arranged in the annular array distribution of bottom column 101 upper end, a plurality of damping springs 103 are fixedly connected with bottom column 101 upper end, and the end of a plurality of damping springs 103 is fixedly connected with movable plate 104, and a plurality of through slots 105 are arranged in the annular array distribution of movable plate 104 inside, upper die seat 002, upper die seat 002 is located in lower die seat 001 upper end, and a plurality of board piece 201 are fixedly connected with upper die seat 002 lower end, and a plurality of guide column 205 are fixedly connected with the annular array distribution of board piece 201 lower end, and guide column 205 is slidably connected with through slot 105, and guide column 205 is slidably connected with directional slot 102, and the operator fixes lower die seat 001 with upper die seat 002 in the specified position in die carrier, and the lower die seat 001 upper end is fixedly connected with punch die lower die, and the upper die seat 002 lower end is fixedly connected with punch die upper die, when needing to stamp the raw material, the operator places the raw material on the lower die seat 001 upper end lower die upper end, then pushes the upper die seat 002 to slide down through the external hydraulic equipment, and the upper die seat 002 drives the upper die and a plurality of board piece 201 to slide down, and guide column 205 slides in through slot 105, and guide column 205 slides to directional slot 102 simultaneously, to ensure that the upper die seat 002 can be subjected to the high -efficient guide effect during the process of sliding down, and keep stable motion track, when the upper die seat 002 slides down appropriate distance, the movable plate 104 upper end is contacted with the board piece 201 lower end, then the movable plate 104 is pushed to slide, and the damping spring 103 is compressed, and the elastic effect of damping spring 103 plays the effect of deceleration at this moment, and the sliding speed of upper die seat 002 is controlled to a certain extent, then the upper and lower dies are closed, and the raw material is stamped into the required shape.

[0024] The cavity 202 is arranged in the board piece 201, the pipeline 203 is fixedly connected with the side wall and communicates with the cavity 202, the valve is arranged in the pipeline 203, the lubricating liquid is conveyed to the cavity 202 by opening the valve in the pipeline 203, and then the valve in the pipeline 203 is closed.

[0025] A plurality of hole grooves 204 are arranged in the annular array distribution of the board piece 201 lower end, the hole groove 204 upper end communicates with the cavity 202 inside, the slot hole 206 is arranged in the guide column 205 upper end, and the slot hole 206 communicates with the hole groove 204 lower end, and the lubricating liquid in the cavity 202 flows to the slot hole 206 inside through the hole groove 204.

[0026] The guide post 205 has a chamber 207 inside, which is connected to the slot 206. The side wall of the guide post 205 has a plurality of holes 208 arranged in a ring array, which are connected to the chamber 207. The lubricating fluid inside the slot 206 flows into the chamber 207, and then flows out of the chamber 207 through the plurality of holes 208. The lubricating fluid flows out to the inner wall of the directional groove 102, lubricating the side wall of the guide post 205 and the inner wall of the directional groove 102, thereby reducing the friction between the side wall of the guide post 205 and the inner wall of the directional groove 102.

[0027] The guide post 205 has an inclined air inlet 209 on its side wall, which is connected to the chamber 207. When the air inlet 209 is blocked, air cannot enter the chamber 207, and a negative pressure is formed inside the chamber 207, preventing the lubricant from flowing out through the hole 208. When the air inlet 209 is open, air enters the chamber 207, and the pressure inside the chamber 207 is balanced with the outside. The lubricant flows out through the hole 208 under the action of gravity or pressure. The air inlet 209 is larger than the hole 208.

[0028] A sealing ring 106 is fixedly connected to the inner wall of the through groove 105. The inner wall of the sealing ring 106 is slidably connected to the side wall of the guide post 205. When the raw material does not need to be stamped, the initial position of the sealing ring 106 is located on one side of the air inlet 209. The air inlet 209 is blocked by the sealing ring 106. When the guide post 205 slides longitudinally, the air inlet 209 slides out from one side of the sealing ring 106, thereby releasing the blockage of the air inlet 209.

[0029] In this invention, when the raw material needs to be stamped, the operator places the raw material on the upper end of the lower die base 001 and the upper die. Then, the upper die base 002 is pushed downward by an external hydraulic device. The upper die base 002 drives the upper die and multiple plates 201 to slide downward. The guide post 205 slides inside the through groove 105 and simultaneously slides into the directional groove 102, thereby ensuring that the upper die base 002 can receive efficient guidance during the downward movement and maintain a stable movement trajectory. When the upper die base 002 slides down an appropriate distance, the upper end of the movable plate 104 contacts the lower end of the plate 201. Then, the movable plate 104 is pushed to slide, and the damping spring 103 is compressed. The elasticity of the damping spring 103 at this moment plays a deceleration role, which controls the downward speed of the upper die base 002 to a certain extent. Then, the upper and lower dies close, and the raw material is stamped into the required shape.

[0030] As the guide post 205 slides downward, the air inlet 209 slides out from one side of the sealing ring 106, releasing the blockage of the air inlet 209. Air enters the interior of the chamber 207, and the pressure inside the chamber 207 is balanced with the outside. Under the action of gravity, the lubricant flows out through the hole 208 and flows out to the inner wall of the directional groove 102, lubricating the side wall of the guide post 205 and the inner wall of the directional groove 102, reducing the friction between the side wall of the guide post 205 and the inner wall of the directional groove 102.

[0031] After the upper and lower molds are demolded and reset, the guide post 205 slides back to its original position, and the air inlet 209 slides to the side of the sealing ring 106. The sealing ring 106 blocks the air inlet 209, preventing air from entering the cavity 207. A negative pressure is formed inside the cavity 207, preventing the lubricant from flowing out through the hole 208.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
