Currently, the model for the Y shape shape tube that different automobile engines use is of different sizes, and smaller model can more save
Engine interior space and the performance for improving engine.For the Y shape shape tube that model is larger, generally use straight to seamless steel pipe
The mode for connecing punching press is completed to process, but this processing method not only easy tos produce seam in punching press joining place, influences whether different
Smoothness, glacing flatness and the fluid throughput of type pipe, and punching press concentrates that Deformation control is improper is susceptible to cracking phenomena, even
Cause to scrap, while single pipe fitting long processing time, low production efficiency, be unfavorable for saving production cost, it is most important that, it is this
Method cannot be used for processing the Y shape shape tube compared with ting model, or even can not use traditional cold-drawing technology, because cold-drawn is elongated
The case where tube body is even broken it is easy to appear crackle etc..
In view of the foregoing, it is necessary to design one kind and can be used in the small-sized Y shape shape tube of drawing and replacement easy to repair
Three-way pipe rolling mould.For this purpose, the applicant has made beneficial design, technical solution described below is this
It is generated under background.
Invention content
The task of the utility model is to provide for a kind of three-way pipe rolling mould, helps with press process mutually to tie cold-drawn
It closes and uses the dynamics for reducing drawing tube body and eliminate the wire drawing phenomenon that traditional cold-drawn processing is generated in tube surfaces, be conducive to excellent
Change mould structure and use the replacement and repair for facilitating parts, improves service life.
What the task of the utility model was performed by, a kind of three-way pipe rolling mould, it is characterised in that including a mould
Seat board offers a through-hole in the middle part of the die holder plate, the circumferencial direction on the one side of the die holder plate and around through-hole
Uniformly distributed there are three mold bases, and the mold base is separately installed with an idler wheel membrane module on one end relative to each other, described
Idler wheel membrane module includes that roller shaft, an idler wheel mould being mounted on roller shaft and a pair being set on mold base is respectively set
Nut on roller shaft and positioned at idler wheel mould both sides, constituting on the circumferencial direction of the idler wheel mould has a circle indent, three
Indent on idler wheel mould cooperates in the center position of through-hole and forms pressure hole, and the shape in the pressure hole is Y-shaped.
In a specific embodiment of the utility model, between being surrounded on the die holder plate on the circumferencial direction of through-hole
It separates and is equipped with screw hole, the mold base is connected with corresponding screw hole by screw and is fixed on die holder plate.
In another specific embodiment of the utility model, the mold base is in one end end structure relative to each other
Cheng Youyi is open, and the idler wheel membrane module is installed on by roller shaft in the opening.
In another specific embodiment of the utility model, the idler wheel mould, which by bearing rotary is arranged, to be rolled
On wheel shaft.
The utility model with the above structure, has the advantage that：Firstly, since three idler wheel moulds are surrounded idler wheel
Axis rotates and cooperates and form Y shape pressure hole, thus idler wheel mould rotation compacting tube body when by pressing hole drawing tube body, not only
The dynamics of drawing tube body is reduced, and eliminates traditional cold-drawing technology the wire drawing that tube surfaces generate the case where, is tied simultaneously
Structure is simple, is easily assembled to, and is advantageous to the replacement and repair of parts, improves service life.
