Abstract
The invention relates to a pressure frame for submerged arc welding machine for thin plate splicing, which includes a half-gantry device, a lifting and rotating device and a double-sided pressure frame device; Guide rail, longitudinal motor reducer, longitudinal wheel set, trolley, transverse guide rail, transverse motor reducer, transverse wheel set, etc., can realize the longitudinal and transverse travel of the pressure frame; the lifting and rotating device consists of a hydraulic station, an oil cylinder, a lifting It is composed of pin shaft, oil cylinder frame, lifting column, guide wheel, slewing bearing, pinion, cycloid reducer, motor, etc., which can realize the lifting and rotating motion of the pressure frame. The longitudinal and lateral movement of the semi-gantry device, the lifting and rotating movement of the lifting and rotating device, and the placement of workpieces in any position and direction are all within the scope of the invention. The two-sided pressure frame is effective and reliable for the two steel plates that need to be spliced. Pressing and cooperating with related welding devices not only ensure the convenience of welding operation and high efficiency, but also ensure the quality of welding.
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...
