Pressure frame used for thin plate splicing submerged arc welding machine

Abstract

The invention relates to a pressure frame used for a thin plate splicing submerged arc welding machine. The pressure frame comprises a half portal frame device, a lifting and rotating device and a dual-side pressure frame device; the half portal frame device is composed of dual transverse beams, a vertical column, an upper end frame, a lower end frame, a longitudinal guide rail, a longitudinal motor speed reducer, a longitudinal wheel set, a trolley, a transverse guide rail, a transverse motor speed reducer, a transverse wheel set and the like, longitudinal and transverse walking of the pressure frame can be achieved, the lifting and rotating device is composed of a hydraulic station, an oil cylinder, a lifting pin shaft, an oil cylinder frame, a lifting vertical column, a guide wheel, a rotation support, a small gear, a cycloidal pin gear speed reducer, a motor and the like, lifting and rotating of the pressure frame can be achieved, and through longitudinal and transverse motion of the half portal frame device and lifting and rotating motion of the lifting rotating device, placing of the workpiece at any position and any direction is in the work range; the dual-side pressure frame device can achieve effective and reliable pressing of two steel plates required to be spliced, and is matched with related welding devices and the like, it is ensured that welding work operation isconvenient, and efficiency is high, and welding quality is ensured.

Description

technical field [0001] The invention relates to the technical field of thin plate splicing, in particular to a pressure frame used for thin plate splicing submerged arc welding machines. Background technique [0002] In industrial production, due to the high welding heat, the submerged arc tailor welding of thin steel plates will cause large deformation of the steel plates, resulting in poor welding quality, and even the welding work cannot be completed. Therefore, the measures of pressing the thin steel plates before welding are usually adopted. There are two pressing methods, one is to use simple guide rails and the welding machine's own weight plus auxiliary pressing iron, and the other is to use double-sided multi-head pressing with a fixed mast. [0003] The method of simple guide rail and welding machine’s self-weight plus auxiliary pressure iron is to place two steel plates spliced ​​by spot welding on a steel platform with better flatness. A simple guide rail is lai...
