The specific embodiment
Below in conjunction with accompanying drawing the utility model and beneficial effect thereof are described in further detail.
Referring to figs. 1 through Fig. 4 b, a kind of production of copper electrolysis drawing die of the special-shaped conducting copper of real core between groove, described drawing die adopts by left and right half die structure dimerous; The inner-cavity structure of this drawing die is followed successively by from the feeding mouth to the discharging opening: inlet region 2, lubricated deformed area 3, sizing area 4, outlet area 5; Described sizing area 4 enlarges the described lubricated deformed area 3 of formation to the feeding mouth end tapering of described mould, and the feeding mouth end face 1 usefulness R10 rounding off of this lubricated deformed area 3 and described mould is formed into oral region 2; Described sizing area 4 enlarges the described outlet area 5 of formation to discharge port end 6 taperings of described drawing die; Equal and the described cupric electrolysis of shape of cross section of described inlet region 2, lubricated deformed area 3, sizing area 4, outlet area 5 is identical with the geomery of the special-shaped conducting copper of real core between groove with described cupric electrolysis with the cross sectional shape size of the consistent and described sizing area 4 of shape of the special-shaped conducting copper of real core between groove.
The length of described drawing die sizing area 4 is 10～13 millimeters, and namely the length h1 of sizing area 4 is desirable 10,11,12 or 13 millimeters,Adopt 3～5 millimeters and this length is general in the prior art, sizing area 4 length after lengthening in the utility model play the effect to the material alignment that stretches when stretching, and the topmost part of drawing die is sizing area, the sizing bandwidth, tensile force is large, and stretched product is straight, and sizing is narrow, tensile force is little, and stretched material can occur bending and deformation.
The length of outlet area 5 is 15～20 millimeters, be desirable 15,16,17,18,19 or 20 millimeters of the length h2 of outlet area 5, described sizing area 4 enlarges with 10 °～15 ° tapering to the discharge port end of described drawing die and forms described outlet area 5, namely this outlet area 5 enlarges with the tapering of 10 °, 11 °, 12 °, 13 °, 14 ° or 15 ° to the discharge port end of described drawing die with described sizing area 4 and forms, thereby and the rigidity that can increase mould prolongs die life with stability; The angle of this outlet area is 45 ° in the prior art, the length 3-5 millimeter of outlet area, and this structure makes mould broken or crack when tensile force is large easily, causes mould to be scrapped.
The surface roughness of described drawing die die cavity is minute surface.
Because the cross section of " ISA method cupric electrolysis special-shaped conducting copper of real core between groove " is complicated, different difference everywhere will guarantee that the percentage elongation that each section stretches must unanimously, guarantee that pulling force is consistent; So described sizing area 4 enlarges with α °, β °, γ ° three kinds of taperings to the feeding mouth end of described drawing die and forms described lubricated deformed areas 3; Should lubricate the zone that deflection is large in the deformed area 3 and adopt little deformation angle α °, the place that deflection is little is adopted large deformation angle γ °, and remaining deformed region adopts β ° deformation angle.Described α ° angle is 5 °～6 °, and β ° of angle is 8 °～10 °, and γ ° of angle is 10 °～13 °, is specially: described α ° angle is 5 ° or 6 °, and β ° of angle is 8 °, 9 ° or 10 °, and γ ° of angle is 10 °, 11 °, 12 ° or 13 °.When deformed area cone angle hour, the stretching blank can not enter die orifice and get stuck easily.
It is 2 °～5 ° the conical surface that profile four limits of described drawing die are cone angle, and the angle that this cone angle is ω ° is specifically got 2 °, 3 °, 4 ° or 5 °This ω ° of conical surface guarantees that the mould installation and removal are convenient; ω ° tapering is less than the critical angle of steel self-locking, and mould can be stayed and be not easy in the die sleeve to fall down during stretching, takes out from die sleeve easily during the mould defectiveness; Die shape adopts tapering to match with die sleeve; Larger at the drawing process pulling force, mould is fitted tightr, the tolerance dimension that easier assurance stretches and expects; Overcome existing half die profile and adopted the mode that compresses with bolt of facing directly, cause because the distortion of bolt is not easy frequently problem of the tolerance dimension of restrained stretching material and die change.
The working modulus of general drawing process is 10～20%.The drawing die cavity dimension, the Containing size tolerance is chosen deviation, and contained size is selected lower deviation.To prolong the life-span of mould.
Processing technology of the present utility model: blanking → forging → roughing → nondestructive inspection → plane blank → car circular hole → plane dies cavity → plane die shape → heat treatment → mill mould faying face → manually repair file to going out finished product.
Specification requirement of the present utility model:
1, material: Cr12.
2, forge the blank of processing mold.
3, blank is carried out nondestructive inspection before the Mould Machining, detect a flaw and come into operation after qualified.
4, the inside of mould, the defective that must not exist slag inclusion, folder ash, pore, crackle, segregation, white point, shrinkage porosite etc. to affect the mould inside quality exists.
5, heat treatment hardness HRC:60-63.
6, inner surface must rounding off from the inlet to the outlet for the inner chamber of mould, and corner angle mustn't be arranged.
