Novel anti-deformation tie piece

Abstract

A novel anti-deformation tie piece is characterized by comprising a tie piece body, a first fixing clamp and a second fixing clamp; the tie piece body is a long columnar metal body; the first fixing clamp and the second fixing clamp are of same structures and symmetrically arranged at the two ends of the tie piece body; the first fixing clamp comprises a first inner clamp body and a first outer clamp body; the second fixing clamp comprises a second inner clamp body and a second outer clamp body as well; by adjusting the positions of the first inner clamp body, the first outer clamp body, the second inner clamp body and the second outer clamp body, a casting is positioned and shaped in advance. The novel anti-deformation tie piece is designed for the welding repairing process of the casting, a traditional mode that the tie piece body is directly welded on the casting is changed, the slidable fixing clamps are arranged on the tie piece body; and meanwhile the fixed distance between the inner clamp bodies and the outer clamp bodies can be adjusted according to the various sizes of the castings, the tie piece can be reused, under the condition that the welding repairing quality is guaranteed, welding material waste is reduced, each casting can save tie piece welding materials by 20 kg, and meanwhile the welding repairing efficiency is improved greatly.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a novel anti-deformation tie bar. Background technique [0002] In the production process of large steel castings, due to the severe thermal, mechanical and chemical effects of molten steel on sand molds, problems such as sand sticking, pores, sand washing, and slag inclusions will inevitably occur. In order to solve these problems, the existing defects must be excavated and repaired by welding. Because preheating, post-heating, welding and other processes are required during the welding repair process, the castings are easily deformed during the repair process due to the heating. The casting is positioned and shaped to avoid thermal deformation. The traditional anti-deformation tie is to directly weld the tie to the casting, which wastes welding materials and welding time, and it is difficult to remove the tie after the casting is reworked.
