Description

Technical Field

[0001] The utility model relates to the field of tool maintenance, in particular to a tooling device for leveling an upper flange plate of a corrugated web steel box girder. Background Art

[0002] In recent years, our company's main business projects are corrugated web steel box girders. During the product manufacturing process, the upper and lower flange plates of the corrugated steel web box girders are greatly deformed after welding. During correction, our company uses a combination of traditional flame correction and external force assistance. The one-time pass rate is low and the correction time is too long, which leads to box volume accumulation in the workshop, seriously affecting the overall production progress and failure to deliver on time.

After discussion, the company focuses on the cold correction of the upper flange plate, which has better effects not only in terms of quality, safety, environment, and cost. The company's special team is committed to improving the upper flange plate correction process tooling equipment to 100% semi-automatic cold correction. The traditional steel plate cold correction and leveling method adopts the method of applying external force and auxiliary tools hydraulic press leveling. According to experience, after the first correction, the deformation points increase and the position becomes smaller, step by step, until the deformation position correction is completed and meets the allowable error. According to the structural characteristics of the corrugated web steel box girder manufactured by our company, the process is changed, external force auxiliary tooling is added, and the deformation correction position is small. After discussion, intermediate cold correction can be used. In the production process, in order to improve the safety factor, from the aspects of safety, quality, management, and environmental protection, it is decided to adopt a new process tooling to make the deformation correction tooling 100% semi-automatic and improve the correction efficiency. The process equipment design task book, new process development input review, product process review record, product design verification and subsequent measures record were carried out. According to the formulated countermeasures, the company used the company's existing inventory of 100t hydraulic jacks to make external force auxiliary tooling. After the tooling was made and installed, it was verified through on-site operation that this tooling is easy to disassemble, has low production cost, is safe to use, and can effectively reduce labor costs, improve work efficiency, and improve product quality. The effect after implementation is mainly reflected in the improvement of the company's quality reputation. Through this innovation, our company rarely encounters quality problems in the production of corrugated web steel box girders, further broadening our company's development space in the steel structure bridge product market.
