Description

Technical Field

[0001] The utility model relates to the technical field of drawing dies, in particular to a hard alloy drawing die. Background Art

[0002] Drawing dies are mechanical equipment that processes large-diameter metal materials into small-diameter materials through drawing dies. Traditional drawing dies do not have lubrication functions. During the drawing process, the dies can only be lubricated manually to avoid damage to the dies. However, manual lubrication is cumbersome, time-consuming and labor-intensive.

[0003] The existing Chinese patent CN216501578U discloses a cemented carbide drawing die with a lubrication function. The cemented carbide drawing die with a lubrication function allows the lifting plate to drive the fixed cylinder to slide upward by rotating the threaded column. When the through hole on the side wall of the fixed cylinder is exposed in the shell, the lubricating oil in the shell can enter the flow hole through the through hole and the fixed cylinder, and then flow out through the flow hole to lubricate the die body. In this way, when the die body is used, the lubricating oil can automatically flow out and then lubricate the die body;

[0004] The above-mentioned cemented carbide drawing die with lubrication function is equipped with a shell for containing lubricating oil in the drawing die, but the shell itself can accommodate less lubricating oil, and the flow holes connected to the shell are relatively concentrated, which will lead to limited flow range of the lubricating oil, thereby reducing the lubrication effect on the die. Utility Model Content

[0005] The utility model aims to provide a cemented carbide drawing die to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cemented carbide drawing die, comprising a drawing die body, wherein a lubrication mechanism is provided on the drawing die body;

[0007] The lubrication mechanism includes a lubricating oil tank, a peristaltic pump, a connecting ring, and an inclined hole. The top of the lubricating oil tank is connected with an oil filling pipe, the input end of the peristaltic pump is connected with the inside of the lubricating oil tank through a pipeline, the output end of the peristaltic pump is connected with a shunt pipe through a pipeline, the bottom of the shunt pipe is connected with a straight pipe, the connecting ring is fixedly installed on the front outer wall of the drawing die body, the inclined hole is arranged inside the drawing die body, and the interior of the inclined hole is connected with the interior of the connecting ring, the bottom end of the straight pipe is connected with the interior of the connecting ring, and a detachable joint is arranged at the connection between the straight pipe and the connecting ring, a plurality of inclined holes are provided, and they are evenly spaced in the upper half of the drawing die body, the interior of the inclined hole is connected with a flow hole, and the flow hole extends to the inner side of the drawing die body away from the end of the inclined hole.

[0008] Furthermore, a slow flow plate is fixedly mounted on the inner wall of the connecting ring, a plurality of slow flow plates are provided, and the slow flow plates separate two adjacent inclined holes, and a through hole is opened on the outer wall of the slow flow plate.

[0009] Furthermore, a placement seat is provided on the outside of the drawing die body, a placement groove corresponding to the drawing die body is opened on the top of the placement seat, a clamping groove is opened on the bottom inner wall of the placement groove, and the protrusion at the bottom of the drawing die body is inserted into the clamping groove, and there are three placement grooves.

[0010] Furthermore, a bracket is fixedly installed on the top of the placement seat, an electric telescopic rod is fixedly installed on the top of the bracket, a limit block is fixedly installed on the extended end of the electric telescopic rod, and the limit block is clamped on the left and right sides of the drawing die body.

[0025] The lubrication mechanism 2 includes a lubricating oil tank 201, a peristaltic pump 202, a connecting ring 206, and an inclined hole 207. The top of the lubricating oil tank 201 is connected with an oil filling pipe, the input end of the peristaltic pump 202 is connected with the inside of the lubricating oil tank 201 through a pipeline, the output end of the peristaltic pump 202 is connected with a shunt pipe 203 through a pipeline, the bottom of the shunt pipe 203 is connected with a straight pipe 204, the connecting ring 206 is fixedly installed on the front outer wall of the drawing die body 1, the inclined hole 207 is arranged inside the drawing die body 1, and the inside of the inclined hole 207 is connected with the inside of the connecting ring 206, the bottom end of the straight pipe 204 is connected with the inside of the connecting ring 206, and a detachable joint is arranged at the connection between the straight pipe 204 and the connecting ring 206, and a plurality of inclined holes 207 are arranged, and they are evenly spaced. The upper half of the drawing die body 1 is arranged, and the interior of the inclined hole 207 is connected with a flow hole 208. The flow hole 208 extends to the inner side of the drawing die body 1 away from the end of the inclined hole 207. A lubricating oil tank 201 is arranged to store lubricating liquid. The lubricating oil in the lubricating oil tank 201 is pumped into the shunt pipe 203 by a peristaltic pump 202. The lubricating oil enters the straight pipe 204 after being shunted by the shunt pipe 203, and then enters the connecting ring 206 from the straight pipe 204, and then flows into the inclined hole 207, and finally flows from the flow hole 208 to the inner side of the drawing die body 1. Because a plurality of inclined holes 207 are arranged in the upper half of the drawing die body 1, it is ensured that the flow range of the lubricating oil is sufficient, and the lubricating oil flowing out can also flow quickly to the lower half of the drawing die body 1 under the action of gravity.

[0026] A slow flow plate 5 is fixedly installed on the inner wall of the connecting ring 206. A plurality of slow flow plates 5 are provided, and two adjacent inclined holes 207 are separated. A through hole is opened on the outer wall of the slow flow plate 5. The slow flow plate 5 is provided to slow down the flow rate of the lubricating oil in the connecting ring 206, so that the amount of lubricating oil in the inclined hole 207 from top to bottom gradually decreases, thereby ensuring that the lubricating oil flows evenly on the inner side of the drawing die body 1;

[0027] A placement seat 3 is provided on the outside of the drawing die main body 1. A placement groove 6 corresponding to the drawing die main body 1 is provided on the top of the placement seat 3.

The limit block 8 is a hollow block to reduce the load acting on the electric telescopic rod 9. The outer wall of the limit block 8 fits with the outer wall of the drawing die main body 1 to ensure the fixing effect of the limit block 8 on the drawing die main body 1.

[0028] One end of the inclined hole 207 away from the connecting ring 206 is inclined toward the center of the drawing die body 1, so that after the lubricating oil enters the inclined hole 207 from the connecting ring 206, it will naturally flow to the depth of the inclined hole 207, and there are three connected flow holes 208 on the same inclined hole 207, so that the lubricating oil in the inclined hole 207 can flow out from different flow holes 208, thereby further increasing the flow range of the lubricating oil.
