An adjusting nut connects with the side of the ball bearing which facing the big diameter of the main shaft. Said adjusting nut is set on the taper-form main shaft and the radial hole is set on the ball bearing casing. The rolling balls which can press the inner tube are set in the holes and the balls are against the main shaft and inner tube. A locking nut is set on the other end of the taper main shaft which links the driving device. The utility model is simple on structure and easy for operation. The strength of the forming force is adjustable and energy-saving. And the comprehensive quality can be controlled easily and the productive efficiency is high, so as to bear a bigger practical value and social economic benefits.
Description
One, technical field
The utility model relates to a kind of device for preparing composite bimetal pipe, is applicable to the production of the composite bimetal pipe of industries such as chemical industry, building, fire-fighting, heat exchange, food processing, medical treatment.
Two, background technology
Multiple tube is the inside and outside two-layer tubing that is formed by combining closely by the metal of unlike material, make by stainless steel and carbon steel as comparatively common stainless steel composite pipe, the method that is used at present to process composite bimetal pipe both at home and abroad has: 1, mechanical hubbing, adhesion between the big and two-layer pipe of the required pulling capacity of this method is inhomogeneous, and regulating the adhesion size needs more mold exchange; 2, machinery spinning method, this method are difficult to process the bigger multiple tube of specification; 3, hydroforming, this method are higher and also higher to the quality requirement of pipeline to the seal request at two ends, and curring time is long; 4, explosion method, this method needs special-purpose place, and the explosive consumption that influence forming quality is difficult to control, and has danger in the operation.
Three, summary of the invention
Task of the present utility model is that to solve existing composite bimetal pipe of poor quality, and ectonexine is in conjunction with shortcoming such as insecure, provide a kind of can be with the set composite of the compound firm preparation composite bimetal pipe of inner and outer pipes.
The utility model is taked following technical scheme for this reason:
A kind of set composite for preparing composite bimetal pipe, include drive unit, be arranged in the interior taper spindle of interior pipe, be socketed in the ball cover on the described taper spindle, described ball overlaps the big side of corresponding taper spindle diameter and is connected with adjusting nut, described adjusting nut is arranged on the described taper spindle, described ball puts and has radial direction through hole, the ball of pipe in can pushing is installed in the described through hole, and described ball offsets with taper spindle, interior pipe respectively; The described taper spindle other end is provided with locking nut; Described taper spindle is connected with drive unit.
Further, described ball is the cydariform ball.
Further, the through hole cross section that puts of described ball and taper spindle axis normal are arranged.
Further, described ball puts and is furnished with three through holes, and described through hole is evenly distributed on ball and puts.
Preparation method described in the utility model has following advantage:
This set composite is simple in structure, easy to operate, formed composite power size can be regulated, and has that energy consumption is low, composite quality is easy to control, the production efficiency advantages of higher, therefore has bigger implementary value and economic results in society.
Four, description of drawings
Fig. 1 represents the utility model operation chart
Pipe 3-taper spindle 4-ball 5-ball cover 6-locking nut 7-adjusting nut in the 1-outer tube 2-
Five, specific implementation method
With reference to accompanying drawing 1, a kind of set composite for preparing composite bimetal pipe, include drive unit, be arranged in the interior taper spindle 3 of interior pipe, be socketed in the ball cover 5 on the described taper spindle, described ball overlaps the big side of corresponding taper spindle diameter and is connected with adjusting nut 7, described adjusting nut is arranged on the described taper spindle, described ball puts and has three radial direction through hole, and through hole cross section that described ball puts and taper spindle axis normal arrange that described through hole is evenly distributed on ball and puts.The ball of pipe in can pushing is installed in the described through hole, and described ball offsets with taper spindle, interior pipe respectively; The described taper spindle other end is provided with locking nut; Described taper spindle is connected with drive unit.
Interior pipe 2 is enclosed within the outer tube 1, adjusting nut 7 is spun on the taper spindle 3 by screw thread, ball cover 5 is provided with equally distributed ball 4 more than 3, the taper spindle 3 that has adjusting nut 7 passes ball cover endoporus, make ball 4 between ball cover 5 and taper spindle 3, can produce radial motion and not break away from ball and overlap 5, the outer end of locking nut 6 locking balls cover prevents that in process of production ball 4 and ball cover 5 come off from taper spindle 3 small ends.
Adopt the preparation method of the composite bimetal pipe of above-mentioned set composite to comprise the steps:
(1), inner and outer pipe is carried out surface treatment;
(2), with the interior pipe outer tube of packing into, the position, school cooperates inner and outer pipe and forms composite pipe blank, and described composite pipe blank is installed on the pedestal;
(3), Installation and Debugging set composite: transfer loose adjusting nut, above-mentioned set composite is arranged in the interior pipe, and then tighten adjusting nut, and determine that by the debugging adjusting nut ball is enclosed within the position on the taper spindle, make the moulding composite force of pipe in the ball extruding reach prefabricated value;
(4) extruding is compound: power set are realized taper spindle rotation and axial feed motion by mechanism, pipe in the extruding of ball rigidity, described taper spindle and ball diameter sum are greater than correspondence position inner tube diameter and inner and outer pipes gap sum, elastic deformation limit value (pipe distortion back perfect plasticity is surrendered in making, and outer tube is still the elastic deformation area) less than the correspondence position outer tube diameter;
(5) inner and outer pipes is compound, takes out set composite, composite bimetal pipe is unloaded bottom base get final product.
Interior pipe 2 is enclosed within earlier in the outer tube 1, and undressed compound tense exists small primary clearance between interior pipe 2 and the outer tube 1, and set composite is built in the interior pipe.During Compound Machining, taper spindle 3 rotates and axial feed motion.The drive ball 4 that rotatablely moves of taper spindle 3 rotates with the cover 5 that rolls; Because taper spindle 3 front portions are pyramidal structure, make ball 4 produce a certain size radial compression power as required, radial compression power size is regulated by adjusting nut 7.Constantly rotatablely moving of taper spindle, pipe 2 reaches surrender in radial direction expansion in making, and because of outer pipe stiffness is big, thereby interior pipe 2 is eliminated mutually with outer tube 1 closely to be contacted with gap, secure fit; Owing to the axial feed motion of taper spindle, make to be compounded in the whole pipe range and finish again.Because taper spindle 3 has certain tapering in the front portion when design, so ball 4 can be between taper spindle 3 and ball cover 5, and the recruitment that radially enlarges according to interior pipe 2 provides required radial compensation at any time; When one timing of taper spindle 3 rotating speeds, determine to roll cover 5 in the position of taper spindle 3 by regulating adjusting nut 7, thus 2 o'clock maximum extrusion pressure of pipe in 4 extruding of definite ball.When adjusting nut 7 moves right, can increase maximum extrusion pressure, otherwise, maximum extrusion pressure then reduced.
