Description

A molybdenum bar processing and forming equipment

Technical Field

The utility model relates to the technical field of molybdenum product production equipment, in particular to molybdenum bar processing and forming equipment.

Background technique

Molybdenum bars are generally used as raw materials to produce other later molybdenum products, such as molybdenum wire, etc., and are usually cylindrical. Existing molybdenum bar processing and molding equipment includes a molding die, and molybdenum powder is fed into the feed port of the molding die through a molybdenum powder conveying mechanism, pressed into shape in the molding die, and then solidified by firing. However, the outer surface of the cylindrical molybdenum bar heats quickly, while the inner core heats slowly, and the heating uniformity is poor, which is not conducive to accelerating the firing efficiency.

Based on this, the existing technology evenly arranges multiple grooves on the outer circumference of the cylindrical molybdenum bar, and the bottom of the groove is close to the inner core of the molybdenum bar to increase the heating speed of the inner core. However, this structural design has the following problems in production: the inner contour section of the forming mold is also designed to be an adaptive shape, but it also makes it difficult to spread the material, which is easy to cause uneven distribution, resulting in different overall structural densities of the pressed molybdenum bar, which does not meet the product design requirements.
