In a preferred embodiment, the material of this patrix 10 and this counterdie 20 is carbon steel.By this, the overall weight of steel pipe shaper 1 can be alleviated on the one hand, the bulk strength of steel pipe shaper 1 can also be improved on the other hand.
Please refer to Fig. 2, it shows the schematic diagram of the second embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 2, the present embodiment is roughly the same with the first embodiment, and difference is: comprise the outer surface that several fixed block 40 is covered in the seam crossing S of this patrix 10 and this counterdie 20 further, in order to be welded to each other fixing by this patrix 10 with this counterdie 20.By this, by the setting of fixed block 40, patrix 10 can be fixedly connected with counterdie 20, after wearing and tearing appear in patrix 10 or counterdie 20, by the mode of gas cutting, fixed block 40 can be destroyed, thus reach the centrifugation between patrix 10 and counterdie 20.
Please refer to Fig. 3, it shows the schematic diagram of the 3rd embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 3, the present embodiment is roughly the same with the first embodiment, difference is: several fixed block 40 is covered in the outer surface of the seam crossing S of this patrix 10 and this counterdie 20, those fixed blocks 40 has multiple fixing hole 41, this patrix 10 and this counterdie 20 are formed with corresponding connecting hole (not shown) relative to those fixing holes 41, several securing member 50 is arranged on corresponding fixing hole 41 with this connecting hole, in order to be interfixed with this counterdie 20 by this patrix 10.By this, by the setting of fixed block 40 with securing member 50, patrix 10 can be fixedly connected with counterdie 20, after wearing and tearing appear in patrix 10 or counterdie 20, by being taken out from fixed block 41 and connecting hole by securing member 50, thus the centrifugation between patrix 10 and counterdie 20 can be reached.
Please refer to Fig. 4, it shows the schematic diagram of the 4th embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 4, the present embodiment is roughly the same with the first embodiment, difference is: this patrix 10 has interface 12 on relative to this counterdie 20, and this counterdie has interface 22 relative to this patrix 10, and on this, interface 12 and this lower interface 22 are welded to each other fixing.
In a preferred embodiment, this is formed with multiple upper storage tank 121 in interface 12, in this lower interface 22 corresponding on those storage tank 121 be formed with multiple lower storage tank 221.One welding block 60 is arranged on this between interface 12 and lower interface 22, and correspondence is arranged among storage tank 121 and lower storage tank 221.By this, due to the setting of upper storage tank 121 and/or lower storage tank 221, can by wherein accommodating for welding block 60, thus ensure that interface 12 and lower interface 22 are pressed close to mutually on patrix 10 and counterdie 20 are when combine, and the Circular external mold 30 making upper semi-circle groove 11 and this lower half circle groove 21 mutually can combine rear one-tenth one to meet shaping standard.
Please refer to Fig. 5, it shows the schematic diagram of the 5th embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 5, the present embodiment is roughly the same with the first embodiment, difference is: this patrix 10 and this counterdie 20 relative to the side of this Circular external mold 30 (in the present embodiment, for the left and right sides) caving inward forms upper dented space 13 and lower recess space 23, and several reinforcement 70 to be arranged on this in dented space 13 and lower recess space 23.It should be noted that the present embodiment only shows the signal situation in wherein a side (left side), be understandable that, the opposite side (right side) do not shown can make identical design with left side.By this, the present embodiment can not need patrix 10 and counterdie 20 all to make solid structure on the one hand, thus plays saving material, alleviates the important effect of steel pipe shaper 1.On the other hand, the design of reinforcement 70 can improve the bulk strength of steel pipe shaper 1, thus increases the service life of steel pipe shaper 1 further.
In addition, the reinforcement 70 being arranged in dented space 13 can be different in quantity and arrangement mode from the reinforcement 70 being arranged in lower recess space 23, thus the strength demand of full different steel pipe shaper 1.
Please refer to Fig. 6, it shows the schematic diagram of the 6th embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 6, the present embodiment is roughly the same with the 5th embodiment, and difference is: the upper dented space 13 of this patrix 10 is provided with multiple through hole 14, and in the lower recess space 23 of counterdie 20, corresponding through hole 14 is provided with multiple through hole 24; Multiple securing member (not shown) is arranged in the through hole 14 of corresponding patrix and the through hole 14 of counterdie in order to be interfixed with this counterdie 20 by this patrix 10.By this, pass through securing member, the setting of the through hole 14 of patrix and the through hole 24 of counterdie, patrix 10 can be fixedly connected with counterdie 20, after there are wearing and tearing in patrix 10 or counterdie 20, by being taken out from the through hole 14 of patrix and the through hole 24 of counterdie by securing member, thus the centrifugation between patrix 10 and counterdie 20 can be reached.
Please refer to Fig. 7, it shows the schematic diagram of the 7th embodiment of the steel pipe shaping mould according to the present invention; As shown in Figure 7; the present embodiment is roughly the same with the first embodiment; difference is: a tubular protective sheath 80 is inserted in this Circular external mold 30, and in order to protect this Circular external mold 30, wherein the hardness of this tubular protective sheath 80 is greater than the hardness of this patrix 10 and this counterdie 20.By this, tubular protective sheath that the present invention adopts hardness higher protection easy dull die mouth in type-approval process, thus the precision problem avoiding mould mouth and cause because of wearing and tearing, raising can service life of steel pipe shaper.
In a preferred embodiment, the material of this tubular protective sheath 80 is wolfram steel.
This tubular protective sheath 80 is detachable to be connected on this patrix 10 and this counterdie 20.In a preferred embodiment, comprise multiple contiguous block 90 to be arranged on corresponding being arranged on tubular protective sheath 80 and by tubular protective sheath and to be fixed to removably on patrix 10 and counterdie 20.And fixed form can for being welded and fixed or being fixed by securing member, but the present invention is not as limit.
By this, when wearing and tearing appear in tubular protective sheath 80, or when needing to shape to the steel pipe of different sizes, can also directly change.
To sum up; the present invention adopts patrix and counterdie to be mutually combined to form steel pipe shaping mould; the mould solving integrally casting formula in prior art easily occurs that intensity is not high; the problems such as easy wearing and tearing; thus the precision that steel pipe is shaped also is ensure that while guarantee mould strength; and due to the mould after improving be stood by patrix and lower module to form; when wearing and tearing appear in certain part in mould; only can replace the patrix of wearing and tearing or counterdie and not need overall replacement, more also improving convenience while ensureing economy.
Further; tubular protective sheath protection easy dull die mouth in type-approval process that the present invention adopts hardness higher; thus avoid mould mouth because wearing and tearing and the precision problem that causes; raising can service life of steel pipe shaper; and tubular protective sheath can also be dismantled; when wearing and tearing appear in tubular protective sheath, or when needing to shape to the steel pipe of different sizes, can also directly change.
The foregoing is only embodiments of the invention, it is also not used to limit scope of patent protection of the present invention.Anyly have the knack of alike those skilled in the art, not departing from spirit of the present invention and scope, the equivalence of the change done and retouching is replaced, and is still scope of patent protection of the present invention.
