Roller, the second roller and the 3rd roller, several positioning holes are offered in the fixed plate, first roller passes through steady pin
In 1 positioning hole installed therein, the 3rd roller is arranged in another positioning hole by steady pin, for pacifying
Fill and push rod be also associated with the steady pin of first roller, also sold on the lower surface of the push rod axis connection have it is described
Second roller, forms the space for clamping pipe fitting between first roller, second roller and the push rod, and described
The curved space for bending pipe fitting is formed between one roller and second roller.
It is further improved to be, the positioning hole at least 2.
Further improved to be, the spacing between first roller, second roller is equal to the diameter of the pipe fitting.
It is further improved to be, at least 1, the 3rd roller.
The beneficial effects of the utility model are：
1st, a kind of device of modularization bending minor diameter thin wall pipe fitting of the utility model, can basis in bending pipe fitting
The diameter of pipe fitting to be bent designs corresponding first roller, the second roller, the 3rd roller, and the first roller, the second roller,
Position of 3rd roller in fixed plate can bend required position according to pipe fitting and be adjusted, and the device has very big
Flexibility.
2nd, because pipe fitting is in bending, the diameter of pipe fitting and the bending arc radius of the first roller or the second roller are one
Cause, so pipe fitting during brake forming, is less prone to tube wall fold or deflated phenomenon, can cause pipe fitting obtain compared with
Good bending quality.
3rd, the utility model modularization is exactly using fixed plate, the first roller, the second roller and steady pin as an entirety
Module, during pipe fitting brake forming, it is only necessary to combine bending position according to fixed plate upper Positioning holes.So add
Work pipe fitting just saves the time of frock, substantially increases labor productivity.
The utility model can solve the buckling problem for the minor diameter thin wall pipe fitting that can not be bent using bending machine at present.Cause
This shaped device practicality is preferable, simple in construction, easy to process, manufacturing cost is low, application easy to spread, has larger practicality
Value.
