Description

A kind of aperture reduction process of deep-hole cylinder tube
Technical field
The present invention relates to the technique that a kind of aperture reduces, in particular, relate to the aperture reduction process of a kind of deep-hole cylinder tube.
Background technology
Deep-hole cylinder tube class workpiece is as a kind of conventional mechanical part, as for piston, hydraulic pressure, oil cylinder etc. occasion, although it has the lubrication of lubricating oil at work, but inevitably there is surface and there is the defects such as scuffing/corrosion or the abrasion aperture change situation that impact seals greatly in its endoporus, so makes deep-hole cylinder tube class workpiece namely not meet instructions for use after application one end time, even scrap.Accordingly, it would be desirable to seek the aperture reduction process of a kind of deep-hole cylinder tube to reduce waste, to increase the service life of workpiece.
Summary of the invention
Based on this, it is an object of the invention to provide and a kind of reduce waste, increase the aperture reduction process of the deep-hole cylinder tube in workpiece service life.
In order to solve problem set forth above, the present invention provides following technical scheme:
A kind of aperture reduction process of deep-hole cylinder tube, it comprises the following steps,
S1, detect and record described internal diameter of cylinder and reduce parameter;
S2, described cylinder barrel cylindrical is carried out turnery processing so that cylinder barrel uniform wall thickness;
S3, use the welding wire identical with cylinder barrel material, and cylinder barrel outer wall is rotated welding, and keep cylinder barrel outer wall layer consistency of thickness, be then slowly cooled to room temperature;
Whether S4, detection internal diameter of cylinder meet the parameter request of the detection in step S1, if met, carrying out step S5, if do not met, being back to step S3 till internal diameter of cylinder meets the requirements;
S5, described inner hole of cylinder is carried out bore hole and honing process.
Further, the aperture in described step S1 reduce numerical value should within 2mm.
Further, in the turnery processing in described step S2, with inner hole of cylinder for positioning datum.
Further, what adopt in described step S3 is that cylinder barrel outer wall is rotated welding by carbon dioxide gas arc welding.
Further, in described step S3, if layer thickness is more than 5mm, also include carrying out the cylinder barrel after welding eliminating the step that stress processes.
Further, the step that described elimination stress processes is heat treatment.
There is advantages that and adopt the method expanded with heat and contract with cold that cylinder barrel outer wall is heated so that cylinder diameter reduces, the advantage that the present invention has clear principle, is easy to operation enforcement, less investment and good economical benefit.
Accompanying drawing explanation
Fig. 1. for the flow chart of aperture reduction process of the deep-hole cylinder tube of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Consulting shown in Fig. 1, the present invention provides the aperture reduction process of a kind of deep-hole cylinder tube, and it comprises the following steps, S1, first, detect and record described internal diameter of cylinder and reduce parameter, and the numerical value that preferably control aperture reduces is within 2mm, to facilitate follow-up rotation welding to operate;
S2, secondly, with inner hole of cylinder for positioning datum, carries out turnery processing to described cylinder barrel cylindrical so that cylinder barrel uniform wall thickness, and when this ensure that follow-up rotation welding, to reduce numerical value also consistent in aperture, and be avoided that the phenomenon that contractility is uneven simultaneously;And using endoporus as positioning datum, it is ensured that during turnery processing, the wall thickness of cylinder barrel keeps uniformly;
S3, then; use the welding wire identical with cylinder barrel material, adopt carbon dioxide gas arc welding that cylinder barrel outer wall rotates welding, and keep cylinder barrel outer wall layer consistency of thickness; then it is slowly cooled to room temperature, as carried out being cooled to room temperature state when room temperature;And in this this step, if the thickness of layer is more than 5mm, to also adopting heat treated mode that cylinder barrel carries out elimination stress process after cylinder barrel outer wall is carried out welding process;
Whether S4, again detection internal diameter of cylinder meet the parameter request of the detection in step S1, if met, carrying out step S5, if do not met, being back to step S3 till internal diameter of cylinder meets the requirements;As: the wall thickness of cylinder barrel is 15mm, then, when layer is 3mm, cylinder diameter can contract 0.3~0.4mm;
S5, last, described inner hole of cylinder is carried out bore hole and honing processes.This is primarily directed to the cylinder barrel of different application occasion, in order to ensure that it meets the requirement of the size of use and precision.
Above-described embodiment is the present invention preferably embodiment; but embodiments of the present invention are also not restricted to the described embodiments; and the change made under other any spirit without departing from the present invention and principle, modification, replacement, combination, simplification; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
