Description

Technical Field

[0001] The invention relates to the technical field of pipe end forming equipment for automobile exhaust system pipe fittings, in particular to automatic loading and unloading pipe end forming equipment. Background Art

[0002] At present, with the development of the automobile industry, the demand for processing automobile parts is increasing, and the control requirements for process costs are also getting higher and higher. Therefore, it is necessary to improve and optimize the pipe processing technology. When using conventional equipment to process pipe fittings in batches, manual hand-held processing is required one process at a time. With the increase in product volume and the processing of different processes, the processing intensity of employees is increasingly unable to be satisfied. In addition, when using conventional equipment to process pipe fittings, the quality of pipe fitting processing is unstable and the stability of the processed products is poor. Therefore, it will cause non-compliance with customer drawing requirements, directly leading to undesirable conditions such as rework and refinishing, which directly affects product quality, increases costs, and reduces product competitiveness.

However, they only perform forming operations on the pipe ends of the pipe fittings, but do not have automatic loading and unloading operations for the pipe fittings. Therefore, they require the assistance of workers to perform processing operations, which makes it difficult to meet the requirements of high-efficiency pipe end forming processing operations.
