Bending machine for small-bore medium pipelines and using method of bending machine

Abstract

The invention discloses a bending machine for small-bore medium pipelines and a using method of the bending machine. The bending machine comprises a working plate which is arranged on a working panel of a transmission case and is connected with a transmission chain of the transmission case, the working plate is provided with a center wheel installed on a center pin shaft and a bending wheel installed on a bending pin shaft, the wheel edge of the center wheel and the wheel edge of the bending wheel are respectively provided with a wheel groove of which the section is in a semi-circle shape, the semi-circle diameter of each wheel groove is matched with the diameter of a bent pipeline, the two sides of the working plate are respectively provided with a piece of stop iron used for installation of stop pin shafts, each piece of stop iron is provided with mechanical limiting positions which are used in cooperation with a limiting pin shaft on the working plate, and the edge of the working plate is provided with a steel angle contact which is used in cooperation with a travel switch which is connected with a switch box and synchronizes with a switch button. By means of the bending machine, the problem that differences exist between angles obtained by an existing bending method and angles used on spot is solved, secondary hand finishing is not needed, labor intensity is relieved, and working efficiency is improved.

Description

technical field [0001] The present invention relates to a machine for stewing pipes and its usage method, more specifically, the present invention relates to a stewing bending machine for stewing hydraulic, pneumatic and other small-diameter medium pipes and its usage method . Background technique [0002] In the mechanical equipment installation project, the steel bars used in civil construction are made of figure 1 The steel bar bending machine shown is for bending processing, and the structure of the steel bar bending machine includes a working disk 1 connected to the transmission box. The method of using it when bending steel bars is: put the steel bar 2 flat on the working disk 1 , so that it is located between the central pin 3 and the eccentric pin 4, when the machine is started to rotate the working disc 1, one end of the steel bar 1 is stopped by the blocking pin 5, so that it cannot follow the When the work disk 1 rotates, since the central pin shaft 3 is fixed, ...

Problems solved by technology

[0004] Although the bending methods of these two kinds of pipes are feasible and commonly used, if the special hydraulic pipe bending equipment is used for the bending process of the pipes, the bending angle may be different from that required on site, and secondary manual trimming is required; Although the manual cold bending method is suitable for the needs of the site, the manual cold bending method is labor-intensive, and the processing speed is slow and the work efficiency is low.
