Abstract
The utility model relates to a spinning diameter fixing device for making a composite cylinder body or a pipeline, which comprises a shaft, a rolling guide, rolling poles, a baffling ring, a supporting frame, a bearing and an adjusting sleeve, wherein the rolling guide is positioned at the front end of the shaft, the rolling poles are uniformly distributed on the external conical surface of the rolling guide and are positioned in the axial direction by the supporting frame and the baffling ring, the bearing is arranged between the supporting frame and the adjusting sleeve, and the adjusting sleeve is connected with the shaft by screw threads and is positioned through screws. When the utility model works, the maximum spinning diameter of the revolution of the rolling poles is determined through adjusting the position of the adjusting sleeve. The utility model has the advantages of simple structure, low cost, convenient operation and high production efficiency, and can rapidly manufacture a composite cylinder body or a pipeline with high accuracy in one-shot forming without injury.
Description
The utility model belongs to machinery processing apparatus, is specifically related to a kind of spinning diameter-setting equipment of making compound cylinder body or pipeline.
Oil cylinder or pipeline adopt homogenous material to make mostly in the prior art, and its performance often satisfies a certain specification requirement and weaken other specification requirement or technical-economic index.As mine support hydraulic prop cylinder body, adopt the 27SlMn material, can satisfy the supporting intensity requirement, but corrosion resisting property is poor, use promptly can occur the corrosion leakage in 6～8 months and need maintenance.Some chemical pipeline adopts stainless steel for another example, has satisfied the anti-corrosion requirement of working media, but has involved great expense, the cost of investment height.
In order to address the above problem, the cylinder body or the pipeline of the compound manufacturing of different metal layer appearred adopting at present, and its combination property improves, but the part that also comes with some shortcomings.As, adopt adhesive with the multiple tube that composite bed and basic unit are bonded together and make, there are deficiencies such as the composite bed bond strength is low, the adhesive solidification time is long, the accuracy of manufacture is low; Adopt drawing method to produce multiple tube, be to utilize broaching machine that composite bed and basic unit are used compound the making of conical pull head repeatedly pulling that varies in size, its composite surface combination is better, but in pulling process, easily produces defectives such as inner surface is pulled, cut, influences the cylinder body quality.
The purpose of this utility model is at the deficiencies in the prior art, and provide a kind of fast, not damaged, one-shot forming make the spinning diameter-setting equipment of compound cylinder body of high accuracy or pipeline.
Technical solution of the present utility model is:
This spinning diameter-setting equipment comprises axle, roll lead, roller, roller back-up ring, roller bearing frame, bearing, regulating sleeve etc.Wherein, roll that to lead be a cylindrical tapered sleeve, be fixedly mounted on the front end of axle; But regulating shaft is distributed on to roll to the roller of position and leads on the outer conical surface, and roller is by roller back-up ring and roller bearing frame axial location; Bearing is arranged between roller bearing frame and the regulating sleeve; Regulating sleeve is connected with male thread and locatees by screw.
During work,, determine that roller rolls the position of leading in taper, thereby determine the maximum spinning diameter of roller revolution, promptly determine to be spun inner diameter of workpiece by adjusting the position of regulating sleeve.
This device is to utilize mechanical spinning principle, roller rotation by tapered arrangement, revolve round the sun and move axially the rotational pressure of generation, the expansion of inner layer metal light wall pipe is combined closely with outer parent tube, and process bright and clean inner surface and high-precision internal diameter size as mirror.In the process, work holder and spinning apparatus can exchange station, and the spinning effect is constant.
This device not only can be used for making new cylinder body or pipeline, but also can repair the cylinder body or the pipeline of corrosion, and the composite bed after the reparation has the effect of strong combination, high accuracy, best bright finish equally.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is the utility model structural representation.
Wherein: 1, wire ring 2, screw 3, roller back-up ring 4, roller 5, end axle 6, roll lead 7, roller bearing frame 8, bearing pin 9, inclined hole 10, bearing 11, cooling fluid hole 12, regulating sleeve 13, screw 14, axle
As shown in the figure, rolling and leading 6 is sleeves of an outer round belt tapering, adopts high hardness material to make, and is fixedly mounted on the front end of axle 14, and fixing by wire ring 1, bearing pin 8 and axle.Roller 4 with high rigidity is distributed on to roll by roller back-up ring 3 and roller bearing frame 7 and leads on 6 the outer conical surface, and roller back-up ring 3 is fixing with roller bearing frame 7 by screw 2.The end face that the roller bearing frame bears the roller axial compressive force is provided with end axle 5, and end axle 5 adopts the high hardness wear-resisting material to make.Also be furnished with inclined hole 9 at roller bearing frame circumference, this inclined hole 9 communicates with axle cooling fluid hole, center 11.For overcoming axial force, between roller bearing frame 7 and regulating sleeve 12, bearing 10 is housed, this bearing adopts thrust ball bearing.Regulating sleeve 12 14 is threaded with axle, adjusts behind the position fixing by screw 13 and axle.
Adopt the utility model manufacturing and repairing composite cylinder or pipeline to have following characteristics:
1, production efficiency height. Can finish 10 centimetres of cylinders of length 110 centimeter inner diameter in 4～5 minutes The neck bush spinning process of body or pipeline.
2, composite bed bond strength height. The bonded area of neck bush and cylinder body or pipeline is 99% More than. In the destructive testing, cylinder body is cut into the rear axially extruding of ring, can't makes the inner bushing ring branch From, can take off after destroying.
3, internal diameter size precision height, linearity is good. The internal diameter size precision can reach ± 0.02mm.
4, inside surface roughness grade height. The smooth interior surfaces that spinning regenerates is bright and clean, The defectives such as the easy inner surface that produces of pultrude process is pulled, cut have been stopped fully. Roughness Grade is more than 7～9 grades.
5, this apparatus structure is simple, and cost of manufacture is low, easy operating.
