Abstract
The invention discloses a method for arranging a stainless steel sleeve in a large-diameter cylinder block in a sleeving way. The method comprises the following steps: firstly, performing boring machining on the inner wall of the cylinder block, manufacturing the stainless steel sleeve according to the size of the machined inner wall of the cylinder block, and machining a triangular thread on the inner wall of the cylinder block; secondly, arranging the stainless steel sleeve in the cylinder body in a sleeving way at the normal temperature, performing hot rolling on the stainless steel sleeve while heating, cooling to the normal temperature after the completion of hot rolling, and performing cold rolling on the stainless steel sleeve at the normal temperature; lastly, honing the inner wall of the stainless steel sleeve by using a honing head. The process is simple, the adhesion between the stainless steel sleeve and the inner wall of the cylinder block is high, and the inner wall of the stainless steel sleeve can meet the requirements of smooth finish and size.
Description
Technical field
The present invention relates to a kind of coal-mine hydraulic support leg surface restorative procedure, particularly relate to a kind of method of major diameter cylinder body inner sleeve stainless steel sleeve.
Background technology
In use for some time, the inner surface of cylinder body there will be the defects such as scuffing, wearing and tearing to coal-mine hydraulic support column, needs to repair its surface.
Restorative procedure of the prior art, one carries out the rear plating iron of boring processing, chromium plating to inner surface of cylinder block, the inboard wall of cylinder block in use easy peeling that this method is repaired; Another kind method is that after carrying out cladding by electric welding, gas welding etc. to inner surface of cylinder block, boring processes, and this method workload is large, cost is high.
Also there is inwall to inlay the method for stainless steel sleeve in prior art, after cylinder body heating, stainless steel sleeve is loaded, a postwelding is carried out to stainless steel sleeve and inboard wall of cylinder block, with honing head, honing is carried out to stainless steel sleeve inwall.But the same easily peeling of the inboard wall of cylinder block that in prior art, the method for inwall edge stainless steel sleeve is repaired, service life is short, and due to stainless steel sleeve thinner, interference fit attire is very easily failed.
Summary of the invention
The object of this invention is to provide a kind of technique simply, the method for the not easily major diameter cylinder body inner sleeve stainless steel sleeve of peeling, long service life.
The object of the invention is to be achieved through the following technical solutions:
The method of major diameter cylinder body inner sleeve stainless steel sleeve of the present invention, comprises step:
First, boring processing is carried out to inboard wall of cylinder block, and make stainless steel sleeve by the size of the inboard wall of cylinder block after processing, at the inwall processing angular thread of described cylinder body;
Then, be loaded in described cylinder body by described stainless steel sleeve under normal temperature, limit heating edge carries out hot roll extrusion to described stainless steel sleeve, is down to normal temperature after hot roll extrusion, carries out cold rolling again under normal temperature to described stainless steel sleeve;
Afterwards, with honing head, honing is carried out to described stainless steel sleeve inwall.
As seen from the above technical solution provided by the invention, the method for the major diameter cylinder body inner sleeve stainless steel sleeve that the embodiment of the present invention provides, owing to carrying out boring processing to inboard wall of cylinder block, and processes angular thread at the inwall of cylinder body; Be loaded in cylinder body by stainless steel sleeve under normal temperature, limit heating edge carries out hot roll extrusion to stainless steel sleeve, is down to normal temperature after hot roll extrusion, carries out cold rolling again under normal temperature to described stainless steel sleeve; With honing head, honing is carried out to described stainless steel sleeve inwall afterwards, technique is simple, stainless steel sleeve and inboard wall of cylinder block tack good and in stainless steel sleeve wall energy meet the requirement of fineness and size.
Accompanying drawing explanation
The structural representation of the stainless steel sleeve reparation column inboard wall of cylinder block that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the structural representation of honing head in the embodiment of the present invention.
In figure:
1, hone stone, 2, oil cylinder, 3, cylinder bar, 4, cylinder body, 5, stainless steel sleeve, 6, angular thread.
Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
The method of major diameter cylinder body inner sleeve stainless steel sleeve of the present invention, preferably detailed description of the invention is as shown in Figure 1 for it:
Comprise step:
First, boring processing is carried out to inboard wall of cylinder block, and make stainless steel sleeve by the size of the inboard wall of cylinder block after processing, at the inwall processing angular thread of described cylinder body;
Then, be loaded in described cylinder body by described stainless steel sleeve under normal temperature, limit heating edge carries out hot roll extrusion to described stainless steel sleeve, is down to normal temperature after hot roll extrusion, carries out cold rolling again under normal temperature to described stainless steel sleeve;
Afterwards, with honing head, honing is carried out to described stainless steel sleeve inwall.
The heating-up temperature of described stainless steel sleeve is more than 723 °.
The wall thickness of described stainless steel sleeve is 1mm to 2mm, the outer wall of described stainless steel sleeve and described cylinder body boring process after inwall between matched in clearance.
The method of the major diameter cylinder body inner sleeve stainless steel sleeve that the embodiment of the present invention provides, utilize stainless steel sleeve to repair column inboard wall of cylinder block, first the inwall of major diameter cylinder body processes triangle thread, then fills stainless steel sleeve under normal temperature, then heats and carry out roll extrusion to stainless steel sleeve.Like this, in rolling process, the tip of triangle thread is heated simultaneously, make to produce between itself and stainless steel sleeve and similarly forge the effect adding steel, forged and pressed together, carry out cold rolling more afterwards, stainless steel sleeve fitted with major diameter cylinder body more closely, the major diameter cylinder surface of reparation not easily peeling, life-span long; Meanwhile, because stainless steel sleeve adopts matched in clearance, normal temperature cold charge, easy construction, reliability are high.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
