Background technique
In hardware manufacture, the manufacture of pipe fitting is very universal, needs to carry out bending processing to pipe fitting in many cases.Generally
Using manually bending, since the rigidity of pipe fitting is relatively good, bending, and every are not easily done by manual hand manipulation
Pipe fitting needs to carry out multiple bending, so spending the very big time very much, and bending efficiency is very low.Therefore, it usually adopts at present
Pipe fitting bending is carried out with electronic bending machine, it is relatively labor-saving in this way, and also bending efficiency also improves.But existing bending machine is still
It so has the following disadvantages: that the pipe fitting after bending can not achieve automatic discharging, while being also not easy to take out from bending machine；For side
Just it assembles, the subsequent operations such as punching is also needed after bending, cause working procedure cumbersome, to influence working efficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of pipe fitting bending and molding works for facilitating automatic discharging and capable of simplifying processing program
Skill.
In order to achieve the above objectives, the technical solution of the present invention is to provide pipe fitting bending molding process, include the following steps:
Step 1: preparing a kind of pipe fitting bending and molding device, including rack, supporting table, remove mechanism, loading mechanism, bending
Mechanism and electromagnet；Bending slot is provided in the supporting table, the bottom of bending slot is fixed with aperture nail；The mechanism that removes includes
The opposite No.1 gear of No.1 rack gear, rotation direction and No. two gears, the No.1 rack gear are engaged in No.1 gear and two simultaneously
