Description

Technical Field

[0001] The utility model belongs to the technical field of industrial production, in particular to a split insert closed die structure of a large hinge beam forging. Background Art

[0002] Artificial diamond is a valuable material in many applications. It has high hardness and good wear resistance and is widely used in cutting, grinding, drilling and other production. The forging equipment used to produce artificial diamond has a large tonnage. Therefore, some accessories in the equipment are also large. The hinge beam forging is the main structural part of the artificial diamond equipment and is produced by die forging. During the production of traditional forging dies, the forging is inside the lower die, and the upper end of the forging extends to the inside of the upper die for forging. After the forging is completed, the forging is ejected by the ejector.

[0003] However, the existing technology has the following shortcomings:

[0004] 1. In the forging process, the forging transfer speed is slow, and the long residence time in the die cavity makes the die temperature high. In addition, the large-sized die has poor hardenability, and the die is prone to annealing. Under the pressure of the large tonnage of the press, the die failure speed is accelerated, resulting in increased die costs. At the same time, the forging will have flash, which reduces the utilization rate of raw materials (utilization rate ≈ 84%).

[0005] 2. After long-term use, the forging die of the prior art is affected by the temperature of the forging during forging. The temperature of the forging die is high, which not only affects the service life of the forging die, but also affects the production quality of subsequent forgings. Utility Model Content

[0006] The purpose of the utility model is to provide a split-insert closed mold structure for large hinge beam forgings. The split-insert closed structure improves material utilization and reduces mold cost, and dissipates heat from the mold sleeve through cooling water, thereby solving the problems of high use cost and low raw material utilization of the prior art forging molds, and the high temperature of the prior art forging molds during use, which affects the service life of the forging molds and also affects the production quality of subsequent forgings.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a split insert closed die structure for large hinge beam forgings, comprising a mounting plate, a die sleeve is fixed on the left side of the upper wall of the mounting plate, a bottom plate is arranged at the bottom of the inner side of the die sleeve, a forging body is arranged above the bottom plate, an upper die is arranged above the forging body, and an insert body is arranged outside the upper die and the forging body;

[0010] Furthermore, eight insert bodies are provided, and two adjacent insert bodies are clearance-matched, and the lower wall of the insert body is in contact with the upper wall of the bottom plate.

[0011] Furthermore, the bottom plate and the die sleeve are clearance matched, a side wall of the insert body away from the forging body is provided with an inclined surface, and the insert body and the die sleeve are clearance matched.

[0012] Furthermore, the insert body is clearance-matched with the upper die, a hydraulic cylinder is fixed at the middle position of the lower wall of the bottom plate, and a steel wire is wound around the outer wall of the insert body.

[0013] Furthermore, the heat dissipation groove is arranged in a U-shape, and the left and right side walls of the mold sleeve and the front and rear side walls of the mold sleeve are all provided with connecting grooves, and the connecting grooves are communicated with the heat dissipation grooves.

[0014] Furthermore, connection holes are provided on the side walls of the corresponding mold sleeves at the two ends of the two tee pipes, and the connection holes are communicated with the corresponding heat dissipation grooves. The remaining end of the tee pipe located on the rear side is fixedly connected to the rear wall of the heat exchange box, and the remaining end of the tee pipe located on the front side is fixedly connected to the water outlet end of the water pump.

[0015] Furthermore, a connecting pipe is fixed to the water inlet end of the water pump, and the other end of the connecting pipe is fixedly connected to the front wall of the heat exchange box, and the upper and lower side walls of the heat exchange box are both provided with cooling fins.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model changes the structure of the mold by arranging an insert body, a mold sleeve, a bottom plate and an upper mold. The split insert body has a closed structure, which improves the material utilization rate and allows the insert body to be replaced at any time due to failure of the mold cavity instead of replacing the entire mold, thereby reducing the use cost of the mold and solving the problems of high use cost and low raw material utilization rate of the forging mold in the prior art.

[0021] 2. The utility model sets a heat exchange box and a water pump, and uses the water pump to circulate cooling water through the die sleeve to cool the die sleeve, so that the die sleeve absorbs the heat of the insert body to dissipate the heat of the insert body, which can avoid the problem of overheating of the die, which affects the service life of the forging die and the production quality of the subsequent forging body. The heat exchange box is used to dissipate the cooling water, which solves the problem that the high temperature of the forging die in the prior art affects the service life of the forging die and the production quality of the subsequent forgings.
