Description
Technical field:
The utility model relates to a kind of pipe material inner wall processing unit (plant), relates in particular to utilize magnetic suspension to fix the processing unit (plant) that floating core head realizes pipe material inner wall is carried out rotary press modelling.
Background technology:
In the prior art, a kind of copper pipe internal thread rotary press modelling device (as shown in Figure 1) is arranged, be to adopt taper floating mandrel (5) to link to each other with floating core head (1), by taper floating mandrel (5) with fixedly cooperating of external mold (4) block taper floating mandrel (5), realize the location of floating core head (1) processing purpose with the realization rotary press modelling.But simultaneously, just require the processed pipe material to have the good ductility energy, otherwise can not produce qualified products because the existence that taper floating mandrel (5) cooperates with fixing external mold (4) has caused the one-off drawing to processed tubing.Existing inner screw thread copper pipe production technology just need be drawn the rosette copper Guan Jingpan that looses, finishing after-combustion rolling, after carrying out recrystallization annealing then and improving the ductility of tubing, could utilize this device to carry out the internal thread machining moulding.This shaped device is owing to contain taper floating mandrel and the fixedly cooperation of external mold, before rotary press modelling, processed copper pipe there is a stretching passage, therefore require processed copper pipe must possess higher extension property, can only adopt copper pipe behind the annealing softening as raw material.Do raw material if adopt hard attitude copper pipe; because of it will bear the stretching of taper floating mandrel and the rotary press modelling of floating core head when the moulding simultaneously; hard again attitude copper pipe tensile property is poor, resistance of deformation is big, thus the time regular meeting cause the fracture of tubing, can't produce qualified products.This shaped device can only carry out machine-shaping under the active force that sets in advance simultaneously, can not adjust automatically along with variation of force, and working (machining) efficiency is low, and crudy can not get guaranteeing.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, aims to provide that a kind of manufacturing procedure passage is few, cost is low, working (machining) efficiency is high, can regulate Working position automatically, and can directly carry out the device of rotary press modelling to the hard state tube material according to shaping resistance.
For achieving the above object, the utility model adopts following technical scheme: a kind of tubing rotary press modelling device, comprise the floating core head that places the tubing inner chamber, correspondence is arranged on the floating core head outside and is pressed at least one pair of symmetrical spinning external mold on the described outer pipe wall, make floating core head and spinning external mold remain the positioner of correspondence position, and one be positioned at the connecting rod that floating core head one side is connected with described positioner along described tubing axis direction, fixedly connected with positioner with described floating core head respectively in the two ends of connecting rod, it is characterized in that: described positioner comprises being connected with described connecting rod one end and is positioned at the iron core of described tubing inner chamber, correspondence is arranged on the coil that the iron core outside is positioned at described tubing outside, and the corresponding position regulator that is arranged at a coil and a side unshakable in one's determination.
Be provided with a protective sleeve between described tubing and described coil, this protective sleeve is made by nonmagnetic substance.
Described position regulator is made up of position sensor that is positioned at described iron core one side and the position sensor that is positioned at the corresponding side of described coil.
The position of described floating core head is to realize controlling by the electric current in the position regulator regulating winding.
Described spinning external mold can be the ball spinning external mold; Also can be roll forming spinning external mold.
The material of described tubing is A1, T2, TP1, TP2, BFe10-1-1, BFe30-1-1, HSn70-1, HA177-2, H62, H68.
As mentioned above, the technical scheme that the utility model provides is with respect to prior art, cancelled taper floating mandrel and fixing external mold, the substitute is iron core and coil, and increased position regulator and overcoat.During work, processed tubing is given active force of floating core head by the spinning external mold time, and coil electricity produces electromagnetic force simultaneously, gives rightabout active force of iron core.Both direction opposite effect power keeps balance in when work, thus with the floating core head relative fixed in the operation interval of spinning external mold, realize rotary press modelling to processed tubing.When any one active force changes because of external influence, the skew of position will be caused, after learning by position regulator induction, do corresponding the variation by the electric current in position regulator control and the regulating winding again, make electromagnetic force change, again realize two rightabout effect equilibrium of forces, thereby guarantee that floating core head is positioned at operation interval all the time, guarantee operating efficiency and crudy.
The utility model compared with prior art has following advantage:
1, owing to cancelled taper floating mandrel and the fixing stretching passage that cooperates of external mold, tensile force to processed tubing reduces, thereby realization is directly carried out rotary press modelling to the hard state tube material and is not ruptured, and processed tubing does not need to anneal passage, has enlarged the range of work;
2, when soft attitude tubing is carried out rotary press modelling, allow to use not rupture, improved production efficiency than the bigger working modulus of prior art;
3, owing to be provided with position regulator, can realize the automatic adjusting of self position, guarantee that floating core head is positioned at the rotary pressing processing district all the time along with environment and variation of force;
4, owing between coil and processed tubing, added protective sleeve, thereby improved widely the service life of coil, reduced cost.
