Description

Technical Field

[0001] The utility model relates to the technical field of mechanical feeding, in particular to a feeding device with deviation compensation and needle breakage prevention. Background Art

[0002] Pipe fittings are hollow, long, round metal pipes that are widely used in industrial pipelines and mechanical structural parts in the fields of petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, they are lighter in weight when the bending and torsional strengths are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures. With the continuous progress and development of modern mechanical processing, the processing accuracy of each process of pipes continues to improve. When pipes are sent to the punching die for punching, related feeding equipment is needed for auxiliary transportation.

[0003] Traditional equipment cannot add the function of dimensional offset compensation at the required multiple-length position, and can only cycle according to the length of a single set of programs. The length of all single pieces is unified, which cannot meet the different length size requirements of the subsequent laser cutting single-piece process after tube making and multiple-length cutting, and has a small scope of application. In addition, when the punching die needle breaks and causes material jamming, the feeding device cannot recognize it and will continue to feed, causing the strip material to accumulate inside the die, resulting in a large amount of waste and mold damage.

[0004] Based on the above technical problems, technical personnel in this field urgently need to develop a feeding device with offset compensation and anti-error needle breakage prevention, which has a simple structure and can effectively solve the different single-piece length size requirements of subsequent processing steps, and can prevent material jamming after the needle breaks in the punching die, thereby reducing waste and mold losses.
