Description
Technical field
The utility model relates to a kind of outer die for copper tubes of crystallizers, specifically a kind of four jiaos of pleat type tapered end moulds.
Background technology
in pulling process, old copper pipe to be repaired, two ends are penetrating, if do not taken measures, copper pipe radian direction just can not obtain enough stretchings and cannot draw, camber line radian direction at copper pipe need to have the power of stretching to impose on it, and way only has the distortion of copper pipe end opening, to pin core head, obtains enough tensile forces.In actual production process, inventor has tried out the method for various deformation copper pipe end opening, be in the past with two symmetrical blunts to pushing up into tapered end shape, irregular to the tapered end form symmetry of pushing up, and materials are many, the original old copper pipe that just lacks material because wearing and tearing again because tapered end is wasted a part of material.
Summary of the invention
The utility model, in order to make up deficiency of the prior art, provides a kind of four jiaos of pleat type tapered end moulds easy to use.
The technical scheme in the invention for solving the technical problem is: a kind of four jiaos of pleat type tapered end moulds, comprise outer mould body, described outer mould body is double-decker, described outer mould body comprises outer outer mould body and the outer mould body of internal layer, the outer mould body of described internal layer is arranged on the inner side of outer outer mould body, the outer mould body of described skin is No. 45 steel matter, the outer mould body of described internal layer is hard chromium, the thickness of the described outer mould body of internal layer is 0.04mm-0.06mm, the outer mould body of described internal layer comprises epimere and hypomere, the inner chamber of described epimere is faced directly and is surrounded by four, and by transition R angle, link together between any two, between described adjacent two R angles, be provided with curved projection, between described adjacent two curved projections and R angle, formed transition groove, the outer surface of described outer mould body comprises outer mould body outer surface epimere and outer mould body outer surface hypomere, described outer mould body outer surface hypomere is back taper setting, the angle of described outer mould body outer surface hypomere and vertical plane is 10-15 degree, on described outer mould body, be provided with hole for hoist.
Further, the thickness of the outer mould body of described internal layer is 0.05mm.
Further, the angle of described outer mould body outer surface hypomere and vertical plane is 12 degree.
The beneficial effects of the utility model are: the utility model not only firmly pins plug head copper pipe distortion, and providing under the prerequisite of enough coupling mechanism force, the length of copper pipe end opening leading edge deformation is reduced to minimum, the utility model cavity shape is four curved projections, four jiaos of excessive grooves, and whole natural transition.Like this, just can be deformed into smoothly the recessed four jiaos of indentation shapes that become pleats in four sides while compressing into tapered end mould copper pipe end opening is squeezed, thereby in the course of the work core head firmly be locked, and symmetry is good, enough tensile force and equilibrant force are provided, have guaranteed copper pipe repairing quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the A-A of Fig. 1 cuts open;
In figure: 1, hole for hoist, 2, outer mould body, 3, outer mould body outer surface epimere, 4, outer outer mould body, 5, epimere, 6, hypomere, 7, outer mould body outer surface hypomere, 8, the outer mould body of internal layer, 9, face 10, R angle, 11, curved projection, 12, transition groove directly.
The specific embodiment
Below in conjunction with accompanying drawing 1 to 2 pairs of the utility model of accompanying drawing, be further described:
A kind of four jiaos of pleat type tapered end moulds, comprise outer mould body 2, described outer mould body 2 is double-decker, described outer mould body 2 comprises outer outer mould body 4 and the outer mould body 8 of internal layer, the outer mould body 8 of described internal layer is arranged on the inner side of outer outer mould body 4, the outer mould body 4 of described skin is No. 45 steel matter, the outer mould body 8 of described internal layer is hard chromium, the thickness of the described outer mould body 8 of internal layer is 0.04mm-0.06mm, the outer mould body 8 of described internal layer comprises epimere 5 and hypomere 6, the inner chamber of described epimere 5 is faced 9 directly by four and is surrounded, and by transition R angle 10, link together between any two, between described adjacent two R angles 10, be provided with curved projection 11, between described adjacent two curved projections 11 and R angle 10, formed transition groove 12, the outer surface of described outer mould body 2 comprises outer mould body outer surface epimere 3 and outer mould body outer surface hypomere 7, described outer mould body outer surface hypomere 7 is back taper setting, described outer mould body outer surface hypomere 7 is 10-15 degree with the angle of vertical plane, on described outer mould body 2, be provided with hole for hoist 1.
