Abstract
The invention relates to a copper pipe outer die of a crystallizer and particularly relates to a four-corner fold type locking head die. The four-corner fold type locking head die comprises an outer die body, wherein the outer die body comprises an outer-layer outer die body and an inner-layer outer die body; the outer-layer outer die body is made of #45 steel; the inner-layer outer die body is a hard chrome plating layer and the thickness is 0.04mm-0.06mm; the inner-layer outer die body comprises an upper section and a lower section; an inner cavity of the upper section is enclosed by four straight faces; the straight faces are connected together by a transition R angle two by two; a curved-surface-shaped bulge is arranged between the two adjacent R angles; a transition groove is formed among the two adjacent curved-surface-shaped bulges and the R angles; the outer surface of the outer die body comprises an outer surface upper section of the outer die body and an outer surface lower section of the outer die body; the outer surface lower section of the outer die body is in an inverted taper shape; the included angle between the outer surface lower section of the outer die body and the vertical surface is 10-15 degrees; the outer die body is provided with a hoisting hole. According to the four-corner fold type locking head die, the repairing quality of a copper pipe is ensured.
Description
Technical field
The present invention 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 present invention, 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 present invention solves the technical scheme that its technical problem takes: 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 invention has the beneficial effects as follows: the present invention 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, cavity shape of the present invention 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 invention;
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 accompanying drawing 2, the present invention is further illustrated:
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.
Further, the thickness of the outer mould body 8 of described internal layer is 0.05mm.
Further, described outer mould body outer surface hypomere 7 is 12 degree with the angle of vertical plane.
Operation principle of the present invention is: the epimere due to the outer mould body 8 of described internal layer in the present invention is four curved projections 11, four jiaos is transition groove 12, and whole natural transition, not only copper pipe distortion firmly can be pinned to plug head, and providing under the prerequisite of enough coupling mechanism force, the length of copper pipe end opening leading edge deformation is reduced to minimum, 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 is firmly locked, and symmetry is good, enough tensile force and equilibrant force are provided, guaranteed copper pipe repairing quality, in addition, the present invention is provided with hole for hoist 1, can very easily the present invention be sling.
Other parts in the present invention adopt prior art, do not repeat them here.
