Description
Technical field
The present invention relates to aluminium-alloy pipe bus process equipment field, specifically a kind of fFour piece type aluminium-alloy pipe bus hydraulic pressure head mould tool.
Background technology
Needed in aluminium-alloy pipe bus production process to the prior making stretching head of its one end, stretching head makes conventional method substantially there are two kinds：The first tightens up its deformation directly to act on aluminium-alloy pipe bus one end with large-tonnage pneumatic hammer by way of hammering pressure into shape；Second is come stretching head processed using upper and lower two-flap type head mould tool by hydraulic way.
The first makes the mode of stretching head, due to being directly to enable aluminum alloy to pipe tube head by way of hammering pressure into shape to deform, consumes energy larger, simultaneously because tube head force part skewness, the stretching head for being formed is in irregular shape, and normal production is made some difference；Additionally, during pressure is hammered into shape, huge metal strike sound can be produced, there is certain noise pollution.
Second mode of making stretching head, main drawback is that：
1. because mould is upper and lower two-flap type structure, made stretching head is hollow, and the phenomenon of " being pulled off " easily occurs in stretching head in drawing process, and continuous production receives certain influence, reduces production efficiency；
2. because mould is upper and lower two-flap type structure, overlap is easily formed at the engaging position of upper and lower two petal tool in head processed, be this, generally, need to carry out second head processed after rotating 90 ° to head processed for the first time, overlap is flattened, increased the labour intensity of operating personnel；
3. due in drawing process, aluminium alloy pipeline itself will be subject to larger tensile force, once aluminium alloy pipeline is pulled off in head and middle part, after stretched processing hardening, when making stretching head is carried out again to it, aluminium-alloy pipe surface is susceptible to tear and cannot make qualified stretching head upper and lower two-flap type head mould tool, and the aluminium-alloy pipe so broken has no idea to reuse, production efficiency is have impact on, lumber recovery is decreased obviously.
The content of the invention
For aluminium-alloy pipe problem present in tradition head technique processed, the invention provides a kind of fFour piece type compo pipe bus hydraulic pressure head mould tool, the lumber recovery of aluminium alloy control head can be preferably ensured, while labor strength can also be reduced.
The technical scheme is that：A kind of fFour piece type aluminium-alloy pipe bus hydraulic pressure head mould tool, including upper mould, lower mould, left side mould and right side mould, there is open slot on the opposite face of the upper die and lower die die body, upper mould open slot is followed successively by tapered opening groove A and semicircle open slot A along feedstock direction, lower die open groove is followed successively by tapered opening groove B and semicircle open slot B along feedstock direction, the position corresponding with tapered opening groove A is provided with the relative tapered opening groove C of notch on the opposite face of the left side mould and right side mould, the opposite face of the left side mould and right side mould position corresponding with semicircle open slot A is plane；The tapered diameter of the tapered opening groove A, tapered opening groove B and tapered opening groove C is gradually reduced along feedstock direction.
The die body portion that upper mould of the present invention is provided with tapered opening groove A is mesa-shaped body, the die body portion that upper mould is provided with semicircle open slot A is cuboid, the die body width of mesa-shaped body portion is gradually reduced along feedstock direction, until consistent with the die body width of rectangle body portion；The lower mould die body has the cuboid of tapered opening groove B for front end, and its width is identical with the die body width of upper mould rectangle body portion.
The die body portion that tapered opening groove C is provided with left side mould of the present invention and right side mould is beloid sphenoid.
The upper end of upper mould die body of the present invention is provided with a rectangular strip boss, and rectangular strip boss is provided with screw, and left side mould is provided with T-shape strip boss with the lateral surface of right side mould, and the bottom of lower mould die body also is provided with a T-shape strip boss.
Compared to traditional aluminium alloy control head method, the advantage that the present invention possesses is：
1., due to being that fFour piece type hydraulic pressure system head mould profile changes tube head shape, made stretching head is real core, solves the phenomenon that " being pulled off " often occurs in aluminium-alloy pipe stretching head, while noiselessness during processing, improves operating personnel's working environment；
2. had using the hydraulic pressure head mould of fFour piece type, pipe tube head is enabled aluminum alloy in horizontal and vertical four direction uniform force, prevent " overlap " phenomenon occur in extrusion process, when making stretching head to it again to the aluminium-alloy pipe that head and middle part are pulled off simultaneously, because aluminium closes pipe surface will not occur tear phenomenon, it is possible to obtain qualified stretching head, the aluminium-alloy pipe broken is utilized again, lumber recovery is improved significantly, and also reduces the working strength of operating personnel.
