Abstract
The invention relates to an execution mode of a hot working process for flared fittings of thin-walled hydraulic steel tubes, which comprises the following steps: determining the size of a flaring, manufacturing a mold, installing a female die, installing a male die, adjusting the protruded head distance of a steel tube, uniformly heating the end tips of the steel tube, stamping the steel tube at the flaring, polishing the obtained product, and inspecting the obtained product. The process disclosed by the invention has the advantages of simplicity in operation, high machining accuracy, capability of optimizing the processing process, improving the production efficiency and reducing the production cost.
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 manufacturing enterprise requires more and more higher to the control of manufacturing cost.On traditional process technology basis, technique is innovated, and reached the means of advanced machining technology level, generally adopted.The cold working of domestic current fluid pressure line is limited by the reason of overseas equipment, and often price is very high, to enterprise, causes very large burden.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, has well solved the problems referred to above.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, provides a kind of simple to operate, and machining accuracy is high, has improved production efficiency, has reduced 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 steel pipe, and male model is for moulding, and the making of male model should be with after enlarging, and horn mouth interior angle, opening diameter are checked as emphasis; Master mold is divided into two, and is two semicircular structures of symmetry, and master mold is consistent to the error that should allow with hydraulic steel pipe caliber with rear caliber;
C, installation master mold:
Master mold is placed in engine lathe scroll chuck, and steel pipe processing termination is placed in master mold;
D, installation male model:
Male model is fixed on tail stock, locking;
E, regulate steel pipe to lift one's head distance:
According to enlarging size, regulate steel pipe to stretch out the distance of master mold termination, scroll chuck is locked;
F, homogeneous heating steel tube head:
Start lathe, rotating speed is unsuitable excessive, is controlled at 100-200r/min, if rotating speed is excessive, can affects and dry rifle heating effect, keeps drying rifle invariant position, homogeneous heating steel tube head to be processed;
G, punching press enlarging place steel pipe:
Heating-up temperature, to 600-1000 degree, treats that enlarging place steel pipe is general red, should with male model, carry out punch forming immediately; During punching press, can not overexert, moulding;
H, grinding process:
Remove the oxide skin producing in process, and with fine sandpaper, inwall is polished, until fineness reaches requirement;
I, check:
Use slide measure check 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: optimized process, simple to operate, machining accuracy is high, has improved production efficiency, has reduced production cost.
accompanying drawing explanation:
Fig. 1 work flow schematic diagram of the present invention
the specific embodiment:
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.
As Fig. 1 shows a kind of embodiment of the heat processing technique of a kind of thin-walled hydraulic steel pipe of the present invention flared fitting: comprise 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 steel pipe, and male model is for moulding, and the making of male model should be with after enlarging, and horn mouth interior angle, opening diameter are checked as emphasis; Master mold is divided into two, and is two semicircular structures of symmetry, and master mold is consistent to the error that should allow with hydraulic steel pipe caliber with rear caliber;
C, installation master mold:
Master mold is placed in engine lathe scroll chuck, and steel pipe processing termination is placed in master mold;
D, installation male model:
Male model is fixed on tail stock, locking;
E, regulate steel pipe to lift one's head distance:
According to enlarging size, regulate steel pipe to stretch out the distance of master mold termination, scroll chuck is locked;
F, homogeneous heating steel tube head:
Start lathe, rotating speed is unsuitable excessive, is controlled at 100-200r/min, if rotating speed is excessive, can affects and dry rifle heating effect, keeps drying rifle invariant position, homogeneous heating steel tube head to be processed;
G, punching press enlarging place steel pipe:
Heating-up temperature, to 600-1000 degree, treats that enlarging place steel pipe is general red, should with male model, carry out punch forming immediately; During punching press, can not overexert, moulding;
H, grinding process:
Remove the oxide skin producing in process, and with fine sandpaper, inwall is polished, until fineness reaches requirement;
I, check:
Use slide measure check enlarging size, and repeat above-mentioned steps F～step I, until be of the required size.
The present invention, by optimal design, makes to have optimized process, and simple to operate, machining accuracy is high, has improved production efficiency, has reduced production cost.
