Description
Technical field
The present invention relates to a kind of processing technology, particularly a kind of heat processing technique of thin-walled hydraulic steel pipe flared fitting.
Background technology
Along with the control overflow of manufacturing enterprise to manufacturing cost is more and more higher.On conventional machining techniques basis, technique is innovated, and reach the means of advanced machining technology level, be generally used.The cold working of domestic current fluid pressure line is limited by the reason of overseas equipment, and often price is very high, causes very large burden to enterprise.In order to address this problem, this technique spy has set forth a kind of thin-walled hydraulic steel pipe flared fitting hot-working enlarging technique, adopts traditional lathe, heat treatment technics and modern processing perfect adaptation, well solves the problems referred to above.
Summary of the invention
The object of the invention is to overcome above deficiency, provide a kind of simple to operate, machining accuracy is high, improves production efficiency, reduces the heat processing technique of the thin-walled hydraulic steel pipe flared fitting of production cost.
Object of the present invention is achieved through the following technical solutions: a kind of heat processing technique of thin-walled hydraulic steel pipe flared fitting, comprises the following steps:
A, determine enlarging size: according to the size of joint caliber, wall thickness, enlarging, determine the size of mould, specification;
B, making mould: be divided into male model, master mold, master mold is used for clamping hydraulic steel pipe, and male model is used for shaping, and the making of male model should with after enlarging, and horn mouth interior angle, opening diameter are checked as emphasis; Master mold is two symmetrical semicircular structures, and master mold is to should be consistent with the error that hydraulic steel pipe caliber allows with rear caliber;
C, installation master mold:
Be placed on by master mold in engine lathe scroll chuck, hydraulic steel pipe processing termination is placed in master mold;
D, installation male model:
Male model is fixed on tail stock, locking;
E, steel pipe is regulated to lift one's head distance:
According to enlarging size, regulate hydraulic steel pipe to stretch out the distance of master mold termination, scroll chuck is locked;
F, homogeneous heating hydraulic steel pipe termination:
Start lathe, rotating speed is unsuitable excessive, controls at 100-200r/min, if rotating speed is excessive, then can affects and dry rifle heating effect, keeps drying rifle invariant position, homogeneous heating hydraulic steel pipe termination to be processed;
G, punching press enlarging place hydraulic steel pipe:
Heating-up temperature, to 600-1000 degree, treats that enlarging place hydraulic steel pipe is general red, should carry out punch forming immediately with male model; Can not overexert during punching press, shaping;
H, grinding process:
Remove the oxide skin produced in process, and with fine sandpaper, inwall is polished, until fineness reaches requirement;
I, inspection:
Use slide measure inspection enlarging size, and repeat above-mentioned steps F ~ step I, until be of the required size.
The present invention compared with prior art has the following advantages: optimize process, simple to operate, and machining accuracy is high, improves production efficiency, reduces production cost.
accompanying drawing illustrates:
Fig. 1 work flow schematic diagram of the present invention
detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this example only for explaining the present invention, does not form limiting the scope of the present invention.
A kind of embodiment of the heat processing technique of a kind of thin-walled of the present invention hydraulic steel pipe flared fitting is shown: comprise the following steps as Fig. 1:
A, determine enlarging size: according to the size of joint caliber, wall thickness, enlarging, determine the size of mould, specification;
B, making mould: be divided into male model, master mold, master mold is used for clamping hydraulic steel pipe, and male model is used for shaping, and the making of male model should with after enlarging, and horn mouth interior angle, opening diameter are checked as emphasis; Master mold is two symmetrical semicircular structures, and master mold is to should be consistent with the error that hydraulic steel pipe caliber allows with rear caliber;
C, installation master mold:
Be placed on by master mold in engine lathe scroll chuck, hydraulic steel pipe processing termination is placed in master mold;
D, installation male model:
Male model is fixed on tail stock, locking;
E, hydraulic steel pipe is regulated to lift one's head distance:
According to enlarging size, regulate hydraulic steel pipe to stretch out the distance of master mold termination, scroll chuck is locked;
F, homogeneous heating hydraulic steel pipe termination:
Start lathe, rotating speed is unsuitable excessive, controls at 100-200r/min, if rotating speed is excessive, then can affects and dry rifle heating effect, keeps drying rifle invariant position, homogeneous heating hydraulic steel pipe termination to be processed;
G, punching press enlarging place hydraulic steel pipe:
Heating-up temperature, to 600-1000 degree, treats that enlarging place hydraulic steel pipe is general red, should carry out punch forming immediately with male model; Can not overexert during punching press, shaping;
H, grinding process:
Remove the oxide skin produced in process, and with fine sandpaper, inwall is polished, until fineness reaches requirement;
I, inspection:
Use slide measure inspection enlarging size, and repeat above-mentioned steps F ~ step I, until be of the required size.
The present invention is by optimal design, and make to optimize process, simple to operate, machining accuracy is high, improves production efficiency, reduces production cost.
