Processing process of screw pipe bending machine

Abstract

The invention relates to a processing process of a screw pipe bending machine, which is used for bending hollow steel pipes. The processing process comprises the following steps of: (1) filling a real object into a hollow steel pipe, sealing both ends of the steel pipe and bending the steel pipe; (2) receding a counter shaft through a driving and reversing mechanism, mounting one end of the steel pipe in a mounting groove of the counter shaft, aligning a bending part to the end part of the counter shaft, and buckling the other end of the steel pipe into a first tooth of a thread groove; (3) forwards impelling the counter shaft through the driving and reversing mechanism until the counter shaft is engaged with a spindle; (4) starting a motor to drive the spindle to rotate and bending and molding the steel pipe along the thread groove of the spindle; (5) receding the counter shaft, taking out the counter shaft through manpower, taking out a processed and molded product and pouring out the real object in the steel pipe; and (6) mounting the counter shaft on an engine base to renewedly produce a next workpiece. The processing process does not need too much manpower so as to reduce the production cost, improve the efficiency and have stable quality.

Description

technical field [0001] The invention relates to a processing technology of a screw tube bending machine. Background technique [0002] Bent pipe products are widely used in people's life and production fields, such as the automobile environmental protection fuel pipe in the automobile fuel tank, its function is mainly to heat up the gasoline in the cold winter, the material of the automobile environmental protection fuel pipe is generally stainless steel, such as No. 304 , No. 316, etc., the diameter of the tubing is generally 12.7MM, and the wall thickness is 1.0MM. However, in reality, the manufacture of automobile environmental protection fuel pipes is generally done by hand, which is labor-intensive and cannot guarantee product quality. And when bending this kind of workpiece, the situation of steel pipe deformation easily occurs, and the yield rate is low, causing unnecessary waste. [0003] Therefore, the industry is badly in need of a processing technology for a scr...
