Description

The seamless steel pipe hydraulic pressure cold drawing machine
Technical field
The utility model relates to the seamless steel pipe technical field of processing equipment, relates in particular to a kind of seamless steel pipe hydraulic pressure cold drawing machine.
Background technology
At present, the technical process of general cold-drawing seamless tube is that the blank steel pipe that needs change caliber and wall thickness is carried out " tup ", be called the blank steel pipe as cold-drawing seamless tube is last, hammer flat, toe with needing the end of the blank steel pipe of cold-drawn processing into shape with pneumatic hammer, so that make the blank steel pipe of hammering into shape can stretch out the die orifice of drawbench draw mould, make the jaw dolly can clamp blank steel tube end part " tup ", carry out draw.This technology was generally used till today from the fifties, had wretched insufficiency, and the waste raw material mainly show:
1. every blank steel pipe needs the length of " tup " to be about 200mm, adds that pulling out the head length degree is about 50mm, calculates according to every blank steel pipe length 6000mm, and only 4% steel consumption has just improved in " tup " portion, causes that lumber recovery is low, waste of raw materials is big.
2. blank steel pipe " tup " rearward end becomes closed state because of distortion, is not easy to the processing of later process.For example cleaning performance is poor, and during cleaning, cleaning agent flows into other end sealing from an end and forms vapour lock, is unfavorable for that cleaning agent enters blank steel pipe inner chamber, is unfavorable for that the cleaning of foreign material such as oxide skin is got rid of, and also is unfavorable for phosphatization, saponification.
3. during seamless pipe moulding fixed length, the tube head that " tup " portion downcuts can only melt down again the stove refining as waste material because of being out of shape seriously, causes the waste of the energy.
Therefore, do not need to damage the blank steel pipe and just can carry out draw, both can reduce the wasting of resources, can use manpower and material resources sparingly again, will profound significance all be arranged the manufacturing enterprise of each seamless steel pipe if the cold-drawing technology of seamless steel pipe is modified into.
The utility model content
Technical problem to be solved in the utility model is: a kind of seamless steel pipe hydraulic pressure cold drawing machine is provided, improves on the basis of existing drawbench, can either reduce equipment investment, can reduce the wasting of resources again, use manpower and material resources sparingly.
For solving the problems of the technologies described above, the technical solution of the utility model is: the seamless steel pipe hydraulic pressure cold drawing machine, comprise blow tank, and a side of described blow tank is provided with pay-off; Be installed on the machine that the pulls out foreground frame of described blow tank downstream position, described pulling out on the frame of machine foreground is installed with external mold; Be installed on the described jaw dolly slideway that pulls out machine foreground frame downstream position, the jaw dolly that is driven by first power set is installed on the described jaw dolly slideway; Be installed on the core bar dolly slideway of described blow tank upstream position, the core bar dolly that is driven by second power set is installed on the described core bar dolly slideway, be installed with core bar on the described core bar dolly, the free end of described core bar is provided with internal mold; Be provided with between described blow tank and the core bar dolly slideway and pull out machine backstage frame, described pull out to be equipped with on the frame of machine backstage be used for axially promoting the hydraulic pressure material-pulling device that blank steel pipe and extruding enter described external mold; Be installed on the protector that is used to prevent the distortion of blank tube bending on the described blow tank; On the jaw of described jaw dolly clamping have with draw after the suitable core of seamless steel pipe internal diameter lining.
As a kind of improvement, described hydraulic pressure material-pulling device comprises the push pedal that is installed on the horizontal rail, has the hole that allows described core bar to pass in the described push pedal, and described push pedal and described pulling out between the frame of machine backstage are provided with first hydraulic cylinder.
As further improvement, described protector comprises the protective cover that is interlocked with described blow tank, and described protective cover is articulated on the described blow tank, and the outside of described protective cover is hinged by second hydraulic cylinder of a linking arm and fixed-site.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because on the production line of existing drawbench, increased and be used for axially promoting the blank steel pipe and push hydraulic pressure material-pulling device that enters external mold and the protector that prevents the distortion of blank tube bending, and be provided with on the jaw dolly with draw after the suitable core of seamless steel pipe internal diameter lining, make the blank steel pipe under the thrust of first hydraulic cylinder, diameter diminishes in the external mold that pulls out machine foreground frame, the wall thickness attenuation, from pulling out after machine foreground frame stretches out one section, in the seamless steel pipe inner chamber behind the core lining insertion reducing of jaw dolly, the clamp of jaw dolly is clamped the bare terminal end that seamless steel pipe exposes, and carries out draw.Compare with existing drawbench, omitted " tup " process, just every steel pipe has just been saved the steel pipe of 250mm, also reduced the highly intensive labour that manpower removes " tup ", make the inner surface quality of steel pipe also be improved simultaneously, for enterprise has reduced production cost, increased economic benefit.
Because protector comprises the protective cover that is interlocked with blow tank, the outside of protective cover is hinged by second hydraulic cylinder of a linking arm and fixed-site, when the pay-off feeding, and the action of second hydraulic cylinder, protective cover is opened, make the blank steel pipe enter blow tank, protective cover fastens then, is pressed on the blank steel pipe, in hydraulic pressure material-pulling device pusher process, the blank steel pipe can not occur bending and deformation because of being subjected to axial resistance, has guaranteed that the blank steel pipe passes smoothly to pull out machine foreground frame, exposes bare terminal end.
