The equipment can make two seam pipes which are embedded together form an integration pipe part with the physical characteristics of the seamless steel pipes by passing the diameter-shrinkage mold and pulled mechanically; the manufacturing cost of the pipe part is far lower than that of the seamless steel pipe; meanwhile, the technical process of machining is extremely simple.
Description
Technical field:
The utility model relates to a kind of complete set of equipments of making seamless steel pipe, especially relates to a kind of complete set of equipments that utilizes the imitative seamless steel pipe of seamed steel pipe manufacturing.
Background technology:
Seamless steel pipe is by being called as valuable relatively raw material such as " spongy iron " and the technical process by complexity is made, and seamed steel pipe is that welding is made after according to the requirement of finished product size of pipe and tubing sheet material being curled, so the seamless steel pipe cost of manufacture is more much higher than seamed steel pipe.But, seamless steel pipe has withstand voltage and anti-good characteristic such as radially reverse, therefore be widely used in the pipeline of the various high-pressure fluids of transmission, seamless steel pipe Another application field is the drilling rod as blast furnace iron notch, and this drilling rod will bear sizable radially rotatory force when work.As seen, these good characteristics of seamless steel pipe be have seam welded tube do not have, yet, have seam welded tube also to have convenient processing and the low attribute of cost, consider from the aspect that reduces cost, get still unsolved so far major subjects for seamless pipe is that people are exploring always with seamed pipe.
In fact, seamed pipe is enough to make its density to increase and performance change by mechanical cold drawing, some characteristic that can possess seamless pipe, problem is to have the weld seam on the seam welded tube to become the defective that can't remedy, and also do not have in the prior art to find can be with method and the complete set of equipments that has seam welded tube to be processed into to have seamless steel pipe characteristic or function.
As the metal tube of carrying fluid to use, it or not merely the branch that has only seamed steel pipe and seamless steel pipe, consider for the anticorrosion aspects that waits, the process technology that has occurred composite bimetal pipe on the market, name as the CN1367050A bulletin is called " production method of composite bimetal pipe " patented technology, this kind composite bimetal pipe is to make its composite pipe blank that forms interference fit by also internally managing the hole enlargement drawing in the outer tube that interior pipe is packed into, again through heating the composite bimetal pipe that processing steps such as diffusion annealing form.Internal diameter tube can adopt anti-corrosion pipe, but internally manage hole enlargement, to caliber outwards be enlarged on original basis, and the density of tube wall is directly dwindled in the enlarged meeting of internal diameter, see that from the anti-radially twisting resistance of pipe and aspect such as withstand voltage this function is not improved, also have complicated technical process simultaneously, and then increase cost of manufacture, can not exchange the function that substitutes seamless steel pipe for the cost that increases cost.
In addition, using the equipment of mechanical drawing pipe fitting or device is technology known to the public, being called " hydraulic drawbench " in the name of CN2037268U bulletin is exactly an example wherein, and the hydraulic drawbench that this kind is used to produce metal tube, rod is called oneself by lathe bed, hydraulic cylinder, drawing-die, drawing dolly, hydraulic circuit system and formed.Its meaning is to want to utilize hydraulic system as driving source, and the drawing dolly makes blank form the shape of pipe or rod through drawing-die under the traction of drawing dolly as the ground-engaging element of drawbench.From the disclosed content of this patent, this kind drawbench just is applicable to seamless pipe or the bar of making reservation shape, even use this kind drawbench also can't produce by the imitative seamless pipe that has seam welded tube to make.
Summary of the invention:
Task of the present utility model provides the complete set of equipments that a kind of utilization has seam welded tube to produce to have the imitative seamless steel pipe of manufacturing of the identical or close function of seamless steel pipe.
The complete set of equipments of the imitative seamless steel pipe of the manufacturing that the utility model proposes have at least one be installed on the fixed support the undergauge mould and by hydraulic mechanism control and drawing assembly that on trapped orbit, move, it is corresponding and can catch the clamp assembly that passes the pipe fitting termination from the undergauge mould to be provided with quantity and position and undergauge mould in this drawing assembly.
Described drawing assembly has that have an a road wheel and inwall and has the housing of predetermined shaft to gradient, be equipped with in the housing with the undergauge mould and remain on clamp assembly on the straight line, and clamp assembly have the Lock Part that is used to catch pipe end and this Lock Part of control finish clamp or unclamp action and be installed in swelling device on its external diameter.Lock Part is a stairstepping by at least two external diameters, and internal diameter is the anchor clamps formation of circular arc, swelling device has the end can be placed on wedge block and the link assembly that moves of control wedge block on the described Lock Part external diameter, this link assembly comprise the transverse bar that is connected with the hydraulic piston end and two ends respectively with the pull bar of transverse bar and wedge block flexible connection.
Described undergauge mould is made of the rigid disc spare that is installed in the fixed support end, and is provided with the stairstepping circular hole at the central module of disc.
The complete set of equipments of the imitative seamless pipe of the manufacturing that the utility model proposed, be that two seamed pipes that nest together are formed the whole pipe fitting with seamless steel pipe physical characteristic by the undergauge mould and after mechanical cold-drawn, this pipe fitting cost of making is well below seamless steel pipe, simultaneously, the technical process of its processing is also quite simple; In addition, this kind complete set of equipments uses basically be exactly clamp, the device of drawing, so the structure of its equipment is quite simple.
Description of drawings:
Accompanying drawing 1 is that the part section master of an embodiment of the utility model looks schematic diagram;
Accompanying drawing 2 is local enlarged diagrams in I place among Fig. 1;
Accompanying drawing 3 be among Fig. 1 A-A to the amplification profile schematic diagram.
The specific embodiment:
Referring to Fig. 1, accompanying drawing 1 provides the overall appearance structure of an embodiment of the utility model.The complete set of equipments of the imitative seamless steel pipe of the manufacturing that the utility model proposes is reached the housing 4 that constitutes drawing assembly and is installed in clamp assemblies 5 in the housing 4 by the undergauge mould 2 and the hydraulic mechanism 3 that are installed on the fixed support 1.
