Description

The concentric process equipment of double end reducing

Technical field

The utility model relates to the machining equipment technical field, the concentric process equipment of particularly a kind of double end reducing.

Background technology

Treadmill is a kind of novel health and fitness facilities, and the parts that cylinder can not lack as treadmill use cylinder form, production method on treadmill a lot.After the high-accuracy cylinder of tradition adopts machining more, the correction of concentricity in addition again, it mainly prepares the cylinder of a hollow, and cylinder must keep more thickness, excise during for machining, it cuts into the conical surface at the cylinder two ends earlier, make central authorities keep the plane, to drive the belt that cylinder covers outward, running band etc., and then prevent that outer covering about ribbon is offset, and at interior external diameter also in cylinder two ends car system concentric holes, device bearing in it, make the cylinder of external diameter when rotating, avoid producing centrifugal action, at the bearing centre device one central shaft is arranged, this central shaft then is fixed on the different structural devices, cylinder is rotated on this apparatus, yet, when finishing this cylinder, the concentric correction that must be rotated, as rotate concentricity not the Jia Shibi vibration that produces centrifugal action rotate, promptly on the cylinder both ends of the surface, hole heavily,, can not produce and rock to reach the concentric of cylinder rotation, yet, this processing operation all has following shortcoming for a long time: the one, and the internal diameter end of cylinder both sides need to divide a secondary operations, so also must twice clamping and take off; The 2nd, because the processing job procedure of sinciput, precision not only time-consuming and coaxial line is wayward, and fraction defective is higher; The 3rd, the external diameter of machined object is easily because of clamping and take off the damage that causes appearance; The 4th, the cylinder internal diameter can't be built into variable thickness by car, and two ends add man-hour, and purport must have the work of concentric correction, and makes the difficulty of cost increase and operation high, and needs experienced professional carry out correction operation; The 5th, cylinder must be reserved the thickness of cutting, so its cylinder weight is to still being difficult to reduction at present, so its material, processing and cost of transportation can't reduce; The 6th, the processing operation is loaded down with trivial details, and process velocity is slow, and causes the waste of material.Accurate requirement for above-mentioned concentric cylinder, and the shortcoming that in processing, causes, equipment with present processing notion and existing machining is difficult to break through improvement, the utility model is prior art bottleneck and the existing cutting machines shortcoming of seeking to achieve breakthrough, through constantly considering the technology of every profession and trade in light of actual conditions, utilize existing single lead screw ex truding briquetting machine, improve the puzzlement in the existing cylinder machine-shaping, it is to adopt present steel pipe single lead screw ex truding briquetting machine the technology of pipe deformation to be reached the precision standard of cylinder double end reducing concentricity.

Prior art TaiWan, China utility model patent ZL20062004598.2 (the concentric process equipment of roller bearing) provides a kind of and can realize the moulding of cylinder two ends and keep the accurate concentricity process equipment of central axis.It is provided with a upper and lower seat at make-up machine, and device has upper and lower mould in seat, is provided with the mould seat in its both sides, and device has shaping mould in the mould seat, is provided with die cavity in the shaping mould, and the die cavity center is run through locating shaft, clamp axis respectively; And run through this oil hydraulic cylinder respectively, so following with the mould seat between be connected by the concentric guide rod cunning of central axis maintenance is established.Guarantee that its interior external diameter of cylinder all keeps the concentricity of an axis.By above-mentioned cylinder under concentric process equipment moulding, external diameter can be fully on same axis in it, and release machining, by the extruding of mould to outer diameter of steel pipes, the external diameter concentricity is accurate in reaching, overcome traditional in the external diameter concentricity because of cutting can not be concentric defective, reduce the correction processing of making the cutting check point in the cylinder two side ends.But also there is following defective in said structure: this concentric process equipment is by a guide rod two ends die holder and die shoe cunning to be established connection, and move together by two side cylinders and upper bolster oil cylinder and to finish, adding man-hour 3 stress points coexists and is difficult on the line guarantee whether two ends are concentric, and when the upper bolster oil cylinder down moves, as above the not same line of die shoe displacement can cause this position distortion, causes two ends not on same straight line.The both sides die holder adopts same guide rod cunning to establish with die shoe to be connected, and causes operation inconvenience, and service time, long slide bar can wear and tear and inconvenience is adjusted, and can only subscription rate change this concentric oil (gas) filling device again.Adopt upper and lower die holder that entire making process is made troubles, flexibility time-consuming and coaxial line is wayward, and the clamping meeting of upper and lower die cavity causes this damage and distortion partly, therefore, remains further to be improved.
