A straight pipe forming guarantee device and process flow

Abstract

The invention discloses a high-precision straight pipe forming guarantee device and technological process. A forming boss punching die device and a composition pipe diameter guarantee device are included. A forming product body is arranged between the forming boss punching die device and the composition pipe diameter guarantee device. The forming boss punching die device comprises a pincher pin. Acore bar is arranged in the puncher pin in a penetrating manner. The high-precision straight pipe forming technological process comprises the following steps of S1, material placement, S2, extruding,S3, forming and S4, oil cylinder reset. The invention relates to the technical field of straight pipe forming. According to the high-precision straight pipe forming guarantee device and technologicalprocess, a pipe diameter die achieves the function of preventing pipe diameter deviation in the boss forming process, the required precision is achieved, and the material return action is completed through combination with a stop block, an equal sleeve, an ejector block and a material return core bar; and by means of the technology, procedures are combined, meanwhile, the precision requirement ofthe outer diameter is guaranteed, forming and outer circle grinding are combined to achieve one-time forming precision punching, efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of straight pipe forming, in particular to a straight pipe forming guarantee device and a process flow. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Before 2004, there was even a vacuum postal express pipeline used to transport mail. Because of its unique characteristics, the pipeline is widely used in many industries and fields. [0003] As the...
