Bending method of to-be-bent pipe fitting for spraying atomization in deodorization equipment

Abstract

The invention discloses a bending method of a to-be-bent pipe fitting for spraying atomization in deodorization equipment. The bending method comprises the following steps that firstly, a positioning support is fixed to a bench vice; secondly, the front end of the to-be-bent pipe fitting penetrates through a pipe bending hole, and the to-be-bent position of the to-be-bent pipe fitting is located at the pipe bending hole; thirdly, a movable screw rod is inserted into an inner hole of the to-be-bent pipe fitting, and a tightening nut is adjusted to enable a supporting ball to be located at the pipe bending hole; fourthly, the right hand applies force through a force applying rod to enable a fixed and movable pulley fixing rotary arm to rotate outwards around a first positioning shaft, and the left hand rotates the tightening nut to enable the supporting ball to be located at the stressed part of the bent pipe fitting all the time; and fifthly, the to-be-bent pipe fitting is bent to the needed angle. By means of the bending method of the to-be-bent pipe fitting for spraying atomization in the deodorization equipment, it can be guaranteed that the bent pipe part is not flat, not wrinkled and not broken, the appearance is smooth, the method is very suitable for product trial-manufacturing and small-batch production, manual operation is easy, investment is small, and the effect is fast.

Description

technical field [0001] The invention relates to deodorizing equipment, in particular to a bending method for a pipe to be bent for spray atomization in the deodorizing equipment. Background technique [0002] In deodorization equipment, many small-diameter thin-walled pipes for spraying and atomization need to be used. These small-diameter thin-walled pipes are laid in the deodorization equipment according to the requirements of the internal structure, and sometimes even need to be installed in the air. It is necessary to bend the small-diameter thin-walled tube to adapt to the internal structure of the deodorizing device. [0003] There is an insurmountable technical problem in the bending of small-diameter thin-walled tubes: either the tube wall at the bend will be wrinkled due to the extrusion during bending, or the circular inner hole at the bend will be This greatly increases the fluid resistance in the tube, and the smaller the bending angle, the more serious the prob...

Problems solved by technology

[0003] There is an insurmountable technical problem in the bending of small-diameter thin-walled tubes: either the tube wall at the bend will be wrinkled due to the extrusion during bending, or the circular inner hole at the bend will be wrinkled due to bending. Squeezed and flattened, which greatly increases the fluid resistance in the tube, the smaller the bending angle, the more serious the problem

Since the pipe fittings to be bent are filled with fine sand, the wrinkling and flattening of the pipe wall at the bend will be much better, but the bend will still be flattened, wrinkled, and even cracked, and the quality is difficult to control
