Rolling device for boss ring of exhaust pipe nozzle of rail engineering vehicle

Abstract

The invention belongs to a processing and manufacturing technology for a boss ring for connection of a pipe orifice of an admission / exhaust pipe of the rail engineering van, and provides a rolling device for the boss ring for the pipe orifice of the exhaust pipe of the rail engineering van. The rolling device for the boss ring for the pipe orifice of the exhaust pipe of the rail engineering van, provided by the invention, comprises a rolling assembly and a clamp (1); the clamp (1) is an opening circular ring opened in an axial direction; the inner wall of the clamp (1) is provided with a concave ring fitted with the boss ring of the exhaust pipe with the boss ring which needs to be rolled; a rolling toolbar (2) of the rolling assembly is fixedly arranged on a tool rest; a rolling tool (3) is sheathed at the upper end of the rolling toolbar (2), and is locked by a locknut (4); the rolling tool (3) is in clearance fit with the rolling toolbar (2) through a rolling tool sheath (5); two ends in the length direction of the rolling tool (3) are respectively provided with a bulge extending to two sides, and the shape of each bulge is the same as the shape of the boss ring of the exhaust pipe with the boss ring which needs to be rolled. The manufacturing accuracy of the boss ring for the pipe orifice of the exhaust pipe of the rail engineering van is met by the rolling device provided by the invention.

Description

technical field [0001] The invention belongs to the processing and manufacturing technology of a boss ring used for connecting the mouth of an intake and exhaust pipe of a rail engineering vehicle, and mainly proposes a rolling device for a boss ring of the mouth of an exhaust pipe of a rail engineering vehicle. Background technique [0002] The exhaust pipe of the rail engineering vehicle is a key component connecting the generator set, the power unit and the corrugated pipe. The precision requirement is high. In the existing technology, the boss ring of the exhaust pipe of the rail engineering vehicle needs non-standard special rolling equipment to complete the production. The professional equipment for connecting the nozzle to the boss ring requires a large investment and high cost, and is suitable for the production of large quantities of products. . For the requirements of single-piece or a small amount of product production, it is also necessary to design economical a...
