Problems solved by technology

Each pass requires heating of the billet and manual replacement of the rotary forging aperture die. The production process requires a lot of manpower, which prolongs the production cycle, low production efficiency, and low product yield.
Moreover, in the process of manual operation, it is unavoidable that the heated blank is oxidized in contact with air, and the MoO formed by oxidation 3 Dissipated in the form of smoke and dust, resulting in the loss of raw materials, and the heating furnace dissipates heat to the environment, causing part of the heat loss
The production site is seriously polluted by noise and smoke and dust, and the environmental conditions are bad

Abstract

The invention discloses a continuous rotary swaging device and method for producing molybdenum rods or molybdenum alloy rods. The continuous rotary swaging device adopts the structure that delivery mechanisms are mounted on a heat-proof and noise-reducing box body, a molybdenum or molybdenum alloy blank is fed from the feed opening of the box body; a molybdenum rod product or a molybdenum alloy rod product is discharged from the discharge opening of the box body; an air extracting mechanism is mounted at the inner top of the box body; the delivery mechanisms adopt a three-stage continuous rotary swaging technology; a spray cooler capable of cooling the molybdenum rods or the molybdenum alloy rods on the fourth delivery mechanism is mounted on the air extracting mechanism above the fourth delivery mechanism. The continuous rotary swaging device has the advantages that the production process is automatic and continuous; the environmental condition of a production field is improved; the problems of oxidation and loss of the product are solved; moreover, the machining dimensional precision of the blank after each machining step is high; the finished product ratio is remarkably improved.

Description

technical field [0001] The invention belongs to the field of metal wires, relates to molybdenum rods or molybdenum alloy rods, and in particular to a continuous swaging device and method for manufacturing molybdenum rods or molybdenum alloy rods. Background technique [0002] High-temperature molybdenum rods and molybdenum alloy rods are molybdenum alloy rods formed by pure molybdenum and molybdenum doped with alloying elements or rare earth elements. They have high recrystallization temperature and excellent high-temperature performance, and can be used as electrode rods and high-temperature furnaces for heating It can also be used as the pre-processing blank of molybdenum and molybdenum alloy wire such as electric light source core wire, bracket and lead-out wire, wire cutting wire. [0003] The traditional rotary forging of molybdenum rods and molybdenum alloy rods is to put the blank into the ten-hole resistance furnace for heating, and then carry out the rotary forging ...
