Background
The telescopic sleeve type (multi-stage) hydraulic cylinder is characterized by small occupied space, long stroke and essential difference from a piston type hydraulic cylinder, is mainly applied to various dump trucks, garbage trucks, engineering machinery, port machinery and agricultural vehicles, and is an important functional part in industrial and agricultural production.
The cylinder of the telescopic hydraulic cylinder has higher precision requirements on the inner and outer cylindrical surfaces, more sealing and guiding grooves and higher requirements, and at present, 3 process methods are available corresponding to different raw materials and performance requirements:
1. blanking by a steel pipe sawing machine, aligning end faces, chamfering, roughly turning a reference position (a frame nest), boring, rolling and pressing holes, finely turning the reference position (the frame nest), turning, sealing, guiding, clamping key holes and grooves, turning an excircle (increasing roughly machined excircle) - (polishing), grinding the excircle, plating a hard path, and polishing and deburring.
2. Blanking by a steel pipe sawing machine, aligning end faces, chamfering, roughly turning a reference position (nest), boring, rolling holes, welding, finely turning the reference position (nest), turning sealing, guiding, clamping key holes and grooves, turning an excircle (increasing roughly machined excircle), grinding the excircle, plating hard chromium, and polishing to remove burrs.
3. Blanking a steel pipe sawing machine, aligning end surfaces, turning reference positions, turning sealing, guiding, clamping key holes and grooves, turning an outer circle (increasing a rough outer circle), grinding the outer circle (polishing), plating hard chromium, and polishing and deburring.
In the above 3 processes, in the process route, because the end face is generally difficult to be flush when the sawing machine is used for blanking, when the end face is chamfered by using the lathe, on one hand, the end face is uneven and easily generates knife resistance to cause damage of a cutter, and often knife resistance also easily causes damage of a driving mechanism of the lathe, on the other hand, the length of the cylinder barrel of the hydraulic cylinder is generally 2-3m, the lathe is fixed at one end of the cylinder barrel of the hydraulic cylinder, which is far away from the chamfer, the three-jaw chuck drives the cylinder barrel to rotate, the cylinder barrel is easily jumped and easily causes knife resistance to occur, therefore, the end face is generally polished and flushed to finish the end face process when the lathe is used for chamfering money, and a large amount of non-processing time is occupied by; the 3 rd process route is a foreign process route, adopts a seamless pipe and a hot-rolled or cold-drawn steel pipe which are different from those in China, has higher raw material cost and process cost, has more potential hazards when being executed without public welfare, has low adaptability to the current domestic market, and is adopted by only a few manufacturers.
In summary, the existing processing technology for the hydraulic cylinder barrel in the industry is mainly used for inheriting the traditional processing technology, on one hand, the process flow is long, occupied fields and equipment are more, the efficiency is low, for large-scale enterprises, the turnover of materials only in the process flow occupies a large amount of non-processing time, turning and turning pins are required to be completed on a lathe, the use of the lathe needs to be trained, and the requirement on the skill of an operator is high; on the other hand, the traditional process is formulated under the earlier seamless steel tube standard, and the deviation of each index of a steel tube blank is larger, so that the process is reasonable, but the traditional method faces to be gradually eliminated under the situation that the deviation of each index is smaller and the intelligent manufacturing trend is more obvious along with the continuous improvement of the quality of the seamless steel tube in recent years. The present invention is directed to making changes to conventional processing methods in such manufacturing contexts to accommodate manufacturing advances.
