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-groove cam type bar end hot-forming mechanism. The planetary gear train-groove cam type bar end hot-forming mechanism is characterized in that the planetary gear train-groove cam type bar end hot-forming mechanism comprises a bar containing platform used for installation of a heated bar 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 main shaft, a planetary carrier body and a sun gear; the motors are fixed to the supporting platforms, the main shafts are coaxially and fixedly connected with driving shafts of the motors, the planetary carrier bodies are coaxially and fixedly connected with the main shafts, and the sun gears are located in the planetary carrier bodies and fixedly connected with the supporting platforms; two planetary gears which are symmetrically arranged along the corresponding sun gear are in shaft connection with the interior of each planetary carrier body and engaged with the corresponding sun gear; a groove cam mechanism is arranged between each planetary gear and the corresponding planetary carrier body, and a forming tool is arranged on each groove cam mechanism. The planetary gear train-groove cam type bar end hot-forming mechanism has the advantages that the ends of the heated bar can form specific shapes after being subjected to squeezing deformation, and the high-quality original bar is provided for rolling of a head-free cross wedge rolling; in addition, the utilization rate of materials is high, the production efficiency is high, and the structure of the whole mechanism is simpler.

Description

Technical field [0001] The invention relates to a hot forming mechanism for the end of a bar in the field of plastic forming and machining, in particular to a planetary gear train that processes the end of a heated bar into a specific shape—groove cam type bar end thermal Forming mechanism. Background technique [0002] In the cross wedge rolling process, the irregular flow of the metal causes the two ends of the rolled piece to be formed into a concave core phenomenon, and the concave core part must be removed as a scrap head, which leads to the normal yield rate of the cross wedge rolling process Below 85%. The original billet of the rolled product 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, truncated, arc, etc. shape, can greatly improve the utilization rate of the rolled material. It is currently the most effective and most versatile process method to realize cross wedge rolling without head. ...
