Problems solved by technology

However, in actual production, the end shape of the bar is generally processed by cutting or forging, and the waste still exists during cutting, and the production efficiency of forging is relatively low, so the current methods cannot meet the production requirements well. And there is a lot of material waste

Abstract

The invention discloses a planetary gear train-constant diameter cam type bar end hot forming mechanism. The planetary gear train-constant diameter cam type bar end hot forming mechanism is characterized by comprising a bar containing platform used for installing heated bars and a bar clamping device; hot forming devices are arranged on the two sides of the bar containing platform respectively; each hot forming device comprises a supporting platform, a motor, a spindle, a planet carrier body and a sun wheel; each motor is fixed to the corresponding supporting platform; each spindle is coaxially and fixedly connected with a drive shaft of the corresponding motor; each planet carrier body is coaxially and fixedly connected with the corresponding spindle; each sun wheel is located in the corresponding planet carrier body and is fixedly connected with the corresponding supporting platform; two planet wheels symmetrically arranged along each sun wheel are coupled in the corresponding planet carrier body; the planet wheels are engaged with the corresponding sun wheels; a constant diameter cam mechanism is arranged between each planet wheel and the corresponding planet carrier body and is provided with a forming cutter. The planetary gear train-constant diameter cam type bar end hot forming mechanism has the advantages that the ends of the heated bars are extruded and deformed to be in a specific shape; high-quality original bars are provided for material-head-free cross wedge rolling; the material utilization rate is high; the material production efficiency is high; and the structure of the whole mechanism is simple.

Description

technical field [0001] The present invention relates to the thermoforming mechanism of the end of the bar in the field of plastic forming and mechanical processing, in particular to a planetary gear system for processing the end of the heated bar into a specific shape—equal diameter cam type bar end thermoforming forming mechanism. Background technique [0002] During the cross wedge rolling forming process, the irregular flow of the metal will cause concavities to appear at both ends of the rolled piece when it is finally formed, and the concavities must be cut off as waste heads, which leads to the general yield rate of the cross wedge rolling process. Below 85%. The original billet of the rolled piece is usually a cylindrical rod. Changing the shape of the end of the bar, such as processing the end of the bar into a conical, frustum-shaped, arc-shaped, etc., can greatly improve the utilization rate of the rolled material. It is currently the most effective and most vers...
