Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: see Fig. 4 and Fig. 5, a kind of porous continuous extrusion die described in the utility model, it comprises one can be placed in extrusion die body 1 in recipient, the leading section of described extrusion die body 1 is provided with an extrusion chamber 5, protruding water conservancy diversion hemisphere 2 is provided with at the center of this extrusion chamber, the bottom even being positioned at surrounding's extrusion chamber 5 of described water conservancy diversion hemisphere 2 is placed with at least five extrusion die cores, and each correspondence of each core rod is provided with the wire hole 4 of cross connection extrusion die body 1 rearward end.
Described extrusion chamber is interior, surrounding's formation one arc foundation ring of water conservancy diversion hemisphere 2, and at least five extrusion die cores are evenly equipped with on arc foundation ring, be provided with a tapered channel passed through smoothly for extruding object in the middle of described extrusion die core, and after this tapered channel, be connected on described wire hole 4.
The material of described core rod 3 is carbide alloy, outlet diameter phi 2.8 ~ φ 6; The base angle, outside 6 of described arc foundation ring is rounding R5 ~ R20, degree of depth 20mm ~ 55mm; The base angle, inner side 7 of described arc foundation ring is rounding R3 ~ R6.
The radius of described water conservancy diversion hemisphere 2 is 1/1 to five/7th of extrusion chamber 5 back cut diameter; The hardness of extrusion die body 1 is HRC45 ~ HRC55.
Extrusion chamber 5 in described porous continuous extrusion die, Main Function retains more than pressure, and continuously extruded to realize, cavity base angle 6 is rounding R5 ~ R20, and less material is in the accumulation at dead angle;
Described porous continuous extrusion die core rod is carbide alloy, effect is the surface smoothness guaranteeing wire rod, improve wearability and the intensity of core rod, equal or when reducing extrusion ratio, outlet diameter phi 2.8 ~ φ 6, a large amount of minimizing following process passage, improves working (machining) efficiency, and significantly reduces and wrap up in core phenomenon.
Described porous continuous extrusion die core rod number is at least 5, both the load that less extrusion ratio alleviates extruder had been maintained, turn improve extruding efficiency, core rod is rounded to be evenly arranged in bottom cone-shaped cavity, ensure that the pressure at each core rod place is substantially equal, thus ensure out the uniformity of linear velocity.
The number of described porous continuous extrusion die wire hole is identical with core rod number, and wire hole connects with core rod, and wire rod is extruded smoothly, also assures that the intensity of extrusion die body, effectively avoids stifled mould phenomenon to occur.
Described porous continuous extrusion die hemisphere radius is 1/1 to five/7th of cavity back cut diameter, hemisphere and cavity bottom junction rounding R3 ~ R6, in extrusion process, shunting served to kamash alloy and reduce extrusion die to the shear stress of line base, and avoid extrusion die center pressure excessive and reduce the life-span.
Shown in Fig. 6, extruding flow process described in the utility model is: by porous continuous extrusion die, namely extrusion die body 1 is mounted to recipient 8 one end, recipient 8 is raised to uniform temperature, alloy pig is put into recipient 8, pressure ram 9 advances and makes alloy pig distortion become line base, when pressure ram 9 stops automatically apart from during the utility model porous continuous extrusion die 3mm ~ 10mm, pressure ram 9 is back to desired location, recipient 8 keeps origin-location to maintain static, in recipient, put next alloy pig into, realize continuously extruded.
Embodiment: the utility model instantiation is shown in Figure 6, kamash alloy ingot diameter phi 80, cavity base angle rounding, hemisphere radius R 13, hemisphere and cavity bottom junction rounding, extrusion die is inlayed into 12 carbide alloy core rods (as Fig. 2).Extrusion ratio is 43.54, originally the single φ 9 of extrusion ratio 70.01(), in the unit interval, output is substantially equal, overall yield rate brings up to 95% by original about 85%, decrease the processing passage between φ 9 ~ φ 3.5, the line base between alloy pig is connected firmly, and follow-up drawing process does not break substantially.Line base surface smoothness and material property improve all greatly, for ZYSnZn70, the line base of the utility model extruding is adopted to be drawn to φ 1.54, tensile strength brings up to 169.82MPa from 161.08MPa compared with former technique, percentage elongation brings up to 57% from 30%, and recipient and kamash alloy ingot are all added to suitable temperature in extrusion process, therefore being squeezed to φ 3.5 can unannealed directly down drawing, former processing technology need increase twice annealing and joint is numerous, easily break in joint, the utility model substantially increases production efficiency, reduces production cost.
