Abstract
The invention relates to a stainless steel seamless steel tube with a precise inner diameter for a hydraulic and pneumatic cylinder, which is mainly used for manufacturing and processing hydraulic and pneumatic elements or being directly processed into cylinder pipes. The stainless steel seamless steel tube with the precise inner diameter for the hydraulic and pneumatic cylinder is made of an austenite stainless steel material instead of a common carbon steel material, the inner surface roughness thereof completely adopts the precision of more than 0.8mum of a nominal value Ra, and the allowable precision deviation of the outer diameter size thereof is improved by one time than that of the steel pipe product made of the common carbon steel material. The stainless steel seamless steel tube with the precise inner diameter for the hydraulic and pneumatic cylinder enhances corrosion resistance and wear resistance of the product, enables the product to adapt to severe and special working environment, has the characteristics of good inner-surface finish, high precision, no need of grinding machining and the like, and further improves the installation precision of the product.
Description
Technical field
The present invention relates to be used for the stainless steel seamless steel tube with precise inner diameter of hydraulic pressure and pneumatic complete sets of equipment, automation equipment.
Background technique
The precise inner diameter seamless steel pipe that is used for hydraulic pressure and pneumatic complete sets of equipment, automation equipment at present, the main Ordinary Steel material that adopts, as 10,20,35, No. 45 steel etc., have characteristics such as internal diameter precision height, tortuosity be little, and have internal surface degree of finish preferably.But along with the technical performance of hydraulic pressure such as the gentle moveable cylinder of hydraulic pressure and automation equipment is more and more higher, technical requirements is more and more higher.Except to precision, the surface finishment proposition requirements at the higher level, more proposed performance requirements such as corrosion resistance, toughness plasticity, and the seamless steel pipe that common carbon steel material is made obviously can not satisfy these high performance requirements.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of hydraulic pressure gentle moveable cylinder stainless steel seamless steel tube with precise inner diameter, be used for hydraulic pressure and pneumatic complete sets of equipment, automation equipment, stainless-steel seamless pipe has higher precision and internal surface degree of finish, and corrosion resistance, wear-resisting property are better.
The technical solution adopted for the present invention to solve the technical problems is: the gentle moveable cylinder stainless steel seamless steel tube with precise inner diameter of a kind of hydraulic pressure, the gentle moveable cylinder of described hydraulic pressure is made by austenitic stainless steel material with stainless steel seamless steel tube with precise inner diameter.
Further, the gentle moveable cylinder of described hydraulic pressure all adopts the above precision of 0.8 μ m of nominal value Ra with the inside surface roughness of stainless steel seamless steel tube with precise inner diameter.Like this, the present invention can be applied directly to pneumatic element or cylinder spare, need not further grinding.
Further, the gentle moveable cylinder of the described hydraulic pressure outside dimension permissible error such as table 1 requirement of stainless steel seamless steel tube with precise inner diameter.The permissible error of the tube product that the ratio of precision Ordinary Steel material of outside dimension permissible error band of the present invention is made is doubled.
Table 1:(unit is mm)
| External diameter | Permissible error |
| ??0～30 | ??+0.10??0 |
| ??＞30～40 | ??+0.18??0 |
| External diameter | Permissible error |
| ??＞40～60 | ??+0.25??0 |
| ??＞60～80 | ??+0.30??0 |
Further, the gentle moveable cylinder of described hydraulic pressure all adopts the required precision of " H9 " with the precision of the permissible error band of the internal diameter size of stainless steel seamless steel tube with precise inner diameter, makes the installation precision of pneumatic element and cylinder spare be further improved.The internal diameter size permissible error such as table 2 requirement of stainless steel seamless steel tube with precise inner diameter of the gentle moveable cylinder of described hydraulic pressure.
Table 2:(unit is mm)
| Internal diameter | Permissible error |
| ??0～30 | ??+0.05??0 |
| ??＞30～40 | ??+0.06??0 |
| ??＞40～60 | ??+0.07??0 |
| ??＞60～80 | ??+0.08??0 |
The invention has the beneficial effects as follows: the gentle moveable cylinder of hydraulic pressure of the present invention adopts austenitic stainless steel material to make with stainless steel seamless steel tube with precise inner diameter, substitute common carbon steel material, be mainly used in manufacturing and processing hydraulic and pneumatic element, also can directly be processed into cylinder tube.The present invention has not only strengthened corrosion resistance, the wear-resisting property of product, make product can adapt to relatively more abominable and working environment in particular cases, have characteristics such as internal surface degree of finish is good, precision height simultaneously, need not grinding again, the installation precision of product is further improved.
Embodiment
The gentle moveable cylinder stainless steel seamless steel tube with precise inner diameter of a kind of hydraulic pressure adopts austenitic stainless steel material, through two rollers and the cold rolling rolling metal processes that waits of three rollers, makes through melting heat treatment admittedly again.The present invention is mainly used in the gentle moveable cylinder of hydraulic pressure, automation equipment etc.Because austenitic stainless steel material has characteristics such as non-hardenable, corrosion resistance, weldability, nonmagnetic and toughness plasticity, the corrosion resistance and the wear resistance of product have been strengthened, made things convenient for processing, made product can adapt to the working environment of relatively more abominable and special circumstances, using scope further enlarges.
Steel pipe length is generally 1m～6m, is 06Cr18Ni11Ti, 06Cr19Ni10,06Cr17Ni12Mo as adopting the trade mark
2, 022Cr17Ni12Mo
2The Austenitic Stainless Steel manufacturing.The steel pipe internal-surface roughness all adopts the above precision of 0.8 μ m of nominal value Ra, makes product can be applied directly to pneumatic element or cylinder spare, need not further grinding.The permissible error of the tube product that the ratio of precision Ordinary Steel material of outer diameter of steel pipes permissible variation in dimension band is made is doubled.The precision of the permissible error band of pipe diameter size all adopts the required precision of " H9 ", makes the installation progress of pneumatic element and cylinder spare be further enhanced.
The present invention has not only strengthened corrosion resistance, the anti-wear performance of product, product can be adapted to relatively badly and the working environment under the special circumstances, have simultaneously the characteristics such as inner surface fineness is good, precision is high, need not again grinding, the installation accuracy of product is further improved.
