Continuous extruding machine for tin brass welding wires and production process based on same

Abstract

The invention discloses a continuous extruding machine for tin brass welding wires. The continuous extruding machine comprises a machine body, a driven extrusion wheel, an extrusion shoe, a driving extrusion wheel, a material blocking block and an extrusion die; a driving shaft is arranged in the machine body, the driving extrusion wheel is fixedly arranged on the driving shaft, the driven extrusion wheel is rotationally installed in the machine body through a rotating shaft, a first extrusion groove is formed in the circumference of the driving extrusion wheel, and a second extrusion groove is formed in the circumference of the driven extrusion wheel; and the extrusion shoe is installed in the machine body, an arc-shaped inclined face is arranged on the side face, facing the driving extrusion wheel, of the extrusion shoe, groove sealing blocks are arranged on the arc-shaped inclined face, the groove sealing blocks is matched with the first extrusion groove of the driving extrusion wheel to form a second extrusion cavity, the material blocking blocks ar efixedly arranged on the arc-shaped inclined surface of the extrusion shoe and are located at the bottom part of the second extrusion cavity, and the bottom part of the second extrusion cavity is closed. The invention further discloses a production process based on the same. According to the continuous extruding machine for thetin brass welding wires and the production process based on the same, energy is saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tin-brass welding wire production, in particular to a tin-brass welding wire continuous extruder and a production process based on the extruder. Background technique [0002] The production of tin brass wire has a history of more than 50 years in our country, and its production process is actually the processing and production process of tin brass wire. There are generally two types of traditional tin-brass welding wire production processes: one is horizontal (or upward) continuous casting wire billet → multi-pass drawing, annealing, pickling → finishing. The second is horizontal continuous casting of ingot → annealing and heating of ingot → four-column hydraulic press extrusion blanking → multi-pass stretching, annealing, pickling → finishing. [0003] Both of the above two processes are based on large-scale equipment and complete sets of units. The process is long and consumes a lot of energy. For exa...

Problems solved by technology

The disadvantages of these two processes are that there are many production processes and high energy consumption. The power consumption of the annealing process alone reaches 30% of the total power consumption, and the total yield is low.

In addition, the traditional extrusion process is to weld the front and rear extrusion parts together through high temperature and high pressure, and then extrude, which is prone to joint defects and the efficiency of extrusion production is low
