Abstract
The invention discloses a method for finish machining an inner hole of a cylinder tube in boring, honing and rolling mode. First, the inner hole of the cylinder tube is roughly bored with a deep hole boring machine; then, the inner hole of the cylinder tube is roughly honed with a deep hole honing machine; next, the inner hole of the cylinder tube is rolled with the deep hole boring machine with a boring cutter replaced by a rolling head. Under the condition that existing machine tool equipment is utilized, the surface quality of the inner hole of the cylinder tube is improved, and machining cost is reduced.
Description
Technical field
The present invention relates to the deep hole fine-processing technique of a kind of column of coal-mine hydraulic support or the earthen pipe of jack, relate in particular to the method for fine finishing that a kind of earthen pipe endoporus takes the boring top gem of a girdle-pendant to roll.
Background technology
At present, the deep hole fine-processing technique of the column of coal-mine hydraulic support or the earthen pipe of jack generally adopts the technique of right boring+roll extrusion Compound Machining or the combination process of scraping+roll extrusion.
In above two kinds of schemes, the bore area quality of the first is analyzed from microcosmic, if the amount of feeding when right boring is excessive, can cause crest to strike the beam, and uses half a year to the phenomenon that occurs peeling after year; The second process program, bore area quality is no problem, and shortcoming is that scraping tumbling special purpose machine tool involves great expense, and is roughly equal to more than 1,000 ten thousand yuan of RMB.
Summary of the invention
The object of this invention is to provide the method for fine finishing that a kind of cost is low, machining accuracy is high earthen pipe endoporus takes the boring top gem of a girdle-pendant to roll.
The object of the invention is to be achieved through the following technical solutions:
The method for fine finishing that earthen pipe endoporus of the present invention takes the boring top gem of a girdle-pendant to roll, comprises step:
First, use deep hole boring machine to carry out heavy boring to earthen pipe endoporus;
Then, use deep hole honing machine to carry out the thick top gem of a girdle-pendant to earthen pipe endoporus;
Afterwards, then use described deep hole boring machine, boring cutter is removed and changes milled head into, roll extrusion is carried out in described earthen pipe Inner hole.
As seen from the above technical solution provided by the invention, the method for fine finishing that the earthen pipe endoporus that the embodiment of the present invention provides takes the boring top gem of a girdle-pendant to roll, owing to first using deep hole boring machine to carry out heavy boring to earthen pipe endoporus; Then use deep hole honing machine to carry out the thick top gem of a girdle-pendant to earthen pipe endoporus; Use again afterwards described deep hole boring machine, boring cutter is removed and changes milled head into, roll extrusion is carried out in described earthen pipe Inner hole.Utilizing under the condition of existing machine tool, improving the surface quality of earthen pipe endoporus, reducing processing cost.
The specific embodiment
To be described in further detail the embodiment of the present invention below.
The method for fine finishing that earthen pipe endoporus of the present invention takes the boring top gem of a girdle-pendant to roll, its preferably the specific embodiment be:
Comprise step:
First, use deep hole boring machine to carry out heavy boring to earthen pipe endoporus;
Then, use deep hole honing machine to carry out the thick top gem of a girdle-pendant to earthen pipe endoporus;
Afterwards, then use described deep hole boring machine, boring cutter is removed and changes milled head into, roll extrusion is carried out in described earthen pipe Inner hole.
For the earthen pipe endoporus of drawing requirement size Φ 400H9 (+0.14,0), the processing dimension of described heavy boring is that Φ 400 (0.05 ,-0.10), roughness are Ra3.2;
The processing dimension of the described thick top gem of a girdle-pendant is that Φ 400 (+0.12,0), roughness are Ra3.2;
The amount of feeding of described roll extrusion is that the rolling quantity on 1.25mm/r, diameter is that 0.08-0.10mm, roughness are Ra0.1-0.2.
The model of described deep hole boring machine is TK2240, and the model of described deep hole honing machine is HTC-4300W.
The present invention is utilizing under the condition of existing machine tool, improved the surface quality of earthen pipe endoporus, the new technology of the heavy boring+thick top gem of a girdle-pendant+roll extrusion has been taked in the fine finishining of endoporus, the feature of this technique is: by honing, eliminated the larger Wave crest and wave trough phenomenon staying after boring, finally again by roll extrusion, surface roughness is significantly improved, dimensional accuracy and surface roughness reach respectively IT9 and Ra0.1-0.2, and on surface, form compression, its effect can compare favourably with scraping tumbling, it has avoided boring to roll the drawback that Compound Machining exists, it makes be expected to be significantly improved the service life of earthen pipe.
Boring machine adds that the cost of honing machine is roughly equal to 3,600,000 yuan of RMB, only has 1/3 left and right of scraping tumbling special purpose machine tool.
Specific embodiment:
The vat pipe orifice drawing requirement size Φ 400H9 (+0.14 of Y204, 0), roughness Ra 0.4, use technical scheme of the present invention, first use deep hole boring machine TK2240 heavy boring that endoporus is processed into Φ 400 (0.05,-0.10), roughness Ra 3.2, re-use deep hole honing machine HTC-4300W Hole honing to Φ 400 (+0.12, 0), Ra3.2, owing to being the thick top gem of a girdle-pendant, roughness is only required Ra3.2, so efficiency is higher, and then get back to deep-hole boring TK2240, boring cutter is removed, simple roll extrusion, the rotating speed of roll extrusion is about 125r/min, feed speed: the 200mm/min(amount of feeding: 1.25mm/r), if rolling quantity Φ 0.08-0.10mm. part length is 1620, be about so 10 minutes and 30 seconds process time.Surface roughness after roll extrusion can reach Ra0.1-0.2, and dimensional accuracy is still controlled within the scope of Φ 400H9.
The beneficial effect that technical solution of the present invention is brought: realized the high-quality processing of earthen pipe endoporus under existing equipment condition, saved 7,400,000 yuan of costs of equipment.
Key problem in technology point of the present invention is by using deep-hole boring and the so common special equipment of deep hole honing machine to realize the high-quality fine finishining of deep hole, and wish protection point is that the boring top gem of a girdle-pendant rolls this new technology scheme.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
