[0045] The technical content of the present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0046] In order to effectively solve the problem that the sintered inserts of polycrystalline diamond wire drawing dies of medium and large specifications in the prior art are prone to quality problems, and the use of large blanks for small-sized molds causes great waste, the present invention provides such figure 1 The shown metal powder pre-pressing device for polycrystalline diamond wire drawing die inserts. The metal powder pre-compression device is suitable for the metal powder pre-compression process with variable pressure values. The metal powder pre-compression process is realized by means of a pressure source operating mechanism with a mechanical jack as the pressure source, a lower pressure head operating mechanism and a pressure value display mechanism. The entire metal powder pre-compression process is easy to operat...
