Welding manufacturing method of hinge support

Abstract

The invention provides a welding manufacturing method of a hinge support. The hinge support comprises a base plate, at least one ribbed plate and at least one lug plate, wherein the ribbed plate is connected with the lug plate and the base plate. The welding manufacturing method of the hinge support comprises the following steps that a base material is cut and then is blanked, so that a rough blank of the lug plate, the ribbed plate and the base plate are obtained; the rough blank of the lug plate is chamfered, so that the lug plate is obtained; and the base plate, the ribbed plate and the lugplate are fixed and welded, so that the hinge support is obtained. The welding manufacturing method of the hinge support has the beneficial effects that the method is easy and convenient to implement, the cost is low, deformation of the obtained hinge support can be controlled, the size is accurate, and the mechanical property is better; and the quality is greatly improved, and thus, the requirements of higher-quality projects can be met.

Description

technical field [0001] The invention relates to the field of bearing engineering, in particular to a method for manufacturing hinge support forgings through manual welding. Background technique [0002] At present, domestic hinge bearings are mostly manufactured by casting technology, which has defects such as pores and cracks, and cannot meet the engineering design requirements of higher quality standards. The main process includes mold preparation, wax pressing, casting and other technological processes, and the hinge support is integrally formed by casting. [0003] A support is a device that connects a structure or a component to a support. In engineering, the component is often supported on the foundation or another stationary component through the support. The hinge bearings act as horizontal restraints at the beam ends. [0004] The manufacturing method of the existing hinge support is casting, which is the manufacturing process of pouring the smelted metal liquid i...

Poor mechanical properties, easy to leave safety hazards for projects with high mechanical properties requirements

[0005] At the same time, with the improvement of quality standards for large-scale projects, some engineering designs require the inspection quality of hinge supports to reach the ultrasonic inspection level I, and castings cannot meet this requirement.
