Description
Technical field:
The utility model relates to the end upsetting field that a kind of length is less than the ultrashort heavy wall tubing pipe nipple of 1 meter, particularly relates to the end upsetting former of ultrashort tubing nipple.
Background technology:
Along with oil exploitation constantly expands, oil well pipe uses and also constantly strengthens thereupon, and oil well pipe pipe nipple is as the part in oil well pipe, and the consumption of oil well pipe pipe nipple also increases thereupon.Oil well pipe thickening pipe nipple because of length short, especially length is less than the oil well pipe pipe nipple of following 1m, adopts conventional oil pipe process for upsetting to process, causes retrogressing to thicken because the clamp segment of oil pipe is too short.Current most steel pipe's production producer all adopts thick-walled pipe machine cut processing molding method to produce, but can by the impact to the even property of wall unevenness of thick-walled pipe with cutting technology, be easy to cause the local wall thickness of pipe nipple not up to standard, need the whole turning of unnecessary wall thickness in the middle part of by body to fall with machine cut processing simultaneously, not only cause the waste of metal material, and machining is costly, time-consuming, economy is very poor, and the qualification rate of product is low.Many steel pipe's production producers are reluctant to accept tubing nipple supply contract, but oil well pipe is often packed and is submitted a tender to manufacturer by client together with tubing nipple, whole oil pipe contract order success rate will be affected as produced the production not accepting tubing nipple, therefore, steel pipe's production manufacturer can only carry out the production of tubing nipple by regardless of expense, can only use thick-walled pipe turnery processing, the production of the tubing nipple of ultrashort thickening is the technical barrier of common concern in the industry.
Applicant is through constantly research and test, successfully test out a kind of end upsetting forming method of ultrashort heavy wall tubing pipe nipple, the method adopts makes base pipe with the middle body same specification body of tubing nipple, the external diameter of base pipe is all identical with the middle body of tubing nipple with internal diameter, by equi-volume process determination base length of tube, base pipe is heated to austenitic state, carries out with ultrashort tubing nipple compression molding device that bi-directional synchronization top is molded obtains ultrashort heavy wall tubing pipe nipple light pipe.
Its molding die process technique flow process:
Blanking---heating---material pipe---the ultrashort heavy wall tubing pipe nipple light pipe of matched moulds---two-way top is molded---that enters mould
Concrete pressing step is given:
The first step, the blanking of thick stock pipe to be added: calculate base length of tube according to the equal-volume method of forming and carry out blanking, the external diameter of base pipe is identical with the middle body of tubing nipple to be processed with internal diameter;
Second step, the heating of base pipe: the base pipe homogeneous heating first step obtained is to austenitic state;
3rd step, base pipe enters mould: start ultrashort tubing nipple three cylinder to top compression molding device, the piston rod of right oil cylinder, Vertical Cylinders and left oil cylinder is made all to be in contraction state, wherein, upper die body moves with on vertical piston bar, be separated with lower mold body, the die cavity of lower mold body is exposed, the pipe to be processed after heating is put into the die cavity of lower mold body;
4th step, matched moulds: start the Vertical Cylinders of ultrashort tubing nipple three cylinder to the shaping press device in top and move down, make upper die body and lower mold body pressing matched moulds, realize the matched moulds of upper die body and lower mold body and treat and process pipe and clamp, clamping position is the middle body portion of tubing nipple to be processed;
5th step, two-way top is molded, obtain ultrashort heavy wall tubing pipe nipple light pipe: the right oil cylinder of synchronous averaging and left oil cylinder, their piston synchronous is stretched, driving right shaping core rod and left shaping core rod synchronously to treat processing pipe, to carry out equal-volume compressing, after compressing, the piston synchronous of right oil cylinder and left oil cylinder is synchronously made to shrink, right shaping core rod and left shaping core rod is driven synchronously to transfer to from heavy wall tubing pipe nipple light pipe, restart Vertical Cylinders to make vertical piston bar drive upper die body moves the demoulding, take out ultrashort heavy wall tubing pipe nipple light pipe.
In this approach, ultrashort tubing nipple three cylinder is the key implementing the method to top compression molding device.
