Embodiment approach

[0036] The upper limit device is a buffer limit cylinder 14 located on both sides of the upper template. The buffer limit cylinder 14 includes a buffer cylinder, a buffer piston rod and an adjusting bolt. The buffer cylinder is installed on the upper template 2, and the buffer piston rod is vertically downward. The lower end of the buffer piston rod is threadedly connected with the adjusting bolt 15. The buffer piston rod of the buffer limit cylinder 14 is pressed against the female template to realize the lower limit that the upper die punches in the female template.

[0037] The lower limiting device is a lateral limiting cylinder 11 horizontally installed on the middle template, the cylinder body of the lateral limiting cylinder 11 is fixed on the middle template 7 through a backing plate 19, and the end of the piston rod of the lateral limiting cylinder 11 passes through The T-shaped block is connected to the lateral limit slide block 12, and some lower limit blocks A are ...

Abstract

The invention relates to a compression molding technique for a tungsten alloy holding-up hammer, and relates to a device for realizing the technique. The innovation points are as follows: the tungsten alloy holding-up hammer provided by the invention is molded through compression by adopting an automatic molding device for the tungsten alloy holding-up hammer; the automatic molding device for the tungsten alloy holding-up hammer comprises a female mold, an upper punch and a lower punch; the technique comprises the following steps: (S1) powder is added; (S2) staging compression is performed for 5 times; the upper punch is used for enabling the female mold to downwards move so as to realize floating compression through the indirect effect of the powder body on the female mold; (S3) after the compression is completed, the pressure maintaining is performed for 56-67 S, and the pressure is relieved; (S4) demolding is carried out. The automatic molding technique and device have the following advantages: as the tungsten alloy holding-up hammer is produced by adopting the powder metallurgy technology, the utilization rate of raw materials is high, and the production cost is low; through the multi-grading compression is combined with the floating compression, the density consistency of products is largely improved, the reject number is decreased, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to an automatic forming process of a tungsten alloy top hammer, and also relates to a device for realizing the forming process. Background technique [0002] Since Bridgman successfully designed a high-pressure device that reaches a pressure above 5 GPa, high-pressure physics has achieved many significant results. For example, materials such as diamond and cubic boron nitride have been synthesized under high temperature and high pressure, and the physical properties of many different substances under high pressure have been studied. However, almost all high-pressure research is inseparable from high-pressure sealing devices, and the top hammer is used as a high-pressure sealing device. One of the key components, the length of its life directly determines the production cost of materials such as diamond and cubic boron nitride. Therefore, effectively improving the service life of tungsten carbide anvil in actual production and str...
