Description
Technical Field
The utility model relates to a non-fixed capping plastic frock belongs to weldment plastic technical field.
Background
The rapid unbalanced heating and cooling of the structural part in the welding process inevitably generates non-negligible welding deformation; welding deformation affects key factors of structural member design integrity, manufacturing process rationality and use reliability. The welding of steel is usually performed by fusion welding, i.e. the welded part is locally heated to melt the welded structural part and the added welding material into liquid metal, forming a molten pool, and then the molten pool is cooled and solidified into solid metal, so that the originally separated structural parts are integrally connected. The structural member is heated in the welding process, the base material except the fusion line expands, and then the base material is cooled, so that the molten pool metal and the base material near the fusion line contract, and the thermal change of heating and cooling is rapidly performed in a local range, so that the expansion and contraction deformation of the structural member are restrained and the plastic deformation is generated. The correcting method of the welding deformation structural part comprises a manual correcting method, a flame heating correcting method and a mechanical correcting method, wherein the manual correcting method is used for hammering the deformation position of the welding part by tools such as a hand hammer, a big hammer and the like, and the correcting method is mainly suitable for bending deformation of small simple welding parts and wave deformation of thin plates; the flame heating correction method is used for locally heating the weldment through flame to enable the weldment to generate new deformation to offset welding deformation, and the method is suitable for correcting the weldment with smaller deformation such as bending deformation, angular deformation, wave deformation, distortion deformation and the like; mechanical straightening corrects welding deformation through a machine or a tool, namely, a jack, a tensioner, a press and the like are used for straightening or flattening a weldment, and the method is generally suitable for weldments made of materials with better plasticity and simple in shape. Some welded slot covers are not suitable for correcting welding deformation by a manual correction method and a flame heating correction method, the cover plate of the slot cover is a square frame formed by welding four steel plates, then a taper sleeve, a skirt plate and the like are welded on the cover plate of the square frame, so that the cover plate of the slot cover is long in welding seam, large in welding amount and complex in structure, the cover plate of the slot cover is in a narrow and long strip shape, and the cover plate of the welded slot cover is seriously deformed, so that the welding deformation of the slot cover is corrected by a mechanical correction method, in the prior art, the slot cover is shaped by the mechanical correction method, a fixed shaping tool is generally used, but the slot cover is shaped by the fixed shaping tool, workers are required to carry the slot cover, and for some large slot covers, the fixed shaping tool cannot accommodate the slot cover, cannot shape the slot cover, has large limitation and large labor intensity of the workers, the shaping efficiency is low.
