Abstract
An oil cylinder piston with copper supporting rings comprises a piston body, and a piston seal ring and a phenolic aldehyde cloth inserted wearing ring are respectively arranged on the outer circle of the piston body. Ring grooves are formed in the two ends of the outer circle of the piston body respectively and used for installing copper supporting rings. The copper supporting rings are two symmetric semicircular rings and installed in the ring grooves in the two ends of the piston body respectively, and the outer diameter of the copper supporting rings is slightly smaller than that of the piston seal ring and that of the phenolic aldehyde cloth inserted wearing ring. The copper supporting rings are added at the two ends of the piston body and have the effects of guiding and supporting and have the effect of protecting the piston seal ring and the phenolic aldehyde cloth inserted wearing ring, the service life of an oil cylinder is prolonged, it is prevented that the oil cylinder piston and a cylinder body are difficult to repair and even scrap after being scuffed, and maintenance cost of the oil cylinder is reduced.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, and particularly a kind of application load variations is large, stroke long, fast large scale hydraulic cylinder piston.
Background technique
Existing hydraulic cylinder piston as shown in Figure 7, is respectively equipped with piston packing ring 2 and phenolic aldehyde folder cloth wear ring 3 on the cylindrical of hydraulic cylinder piston body 1.The problem of existing hydraulic cylinder piston is: the cylinder body of hydraulic jack and piston all adopt steel construction piece to make, in the time that piston does high speed to-and-fro motion in cylinder body, piston packing ring 2 and the 3 easily wearing and tearing of phenolic aldehyde folder cloth wear ring, once piston packing ring 2 and 3 wearing and tearing prematurely of phenolic aldehyde folder cloth wear ring, piston face easily can produce collision and occur pulling phenomenon with inboard wall of cylinder block, occurs pulling the rear normal reparation that is difficult to; The requirement of piston accuracy of manufacturing is high besides, and cost is also high.
Summary of the invention
The purpose of this utility model is overcome the above-mentioned deficiency of prior art and a kind of oil cylinder piston with copper support ring is provided, increase respectively a copper supporting ring at the outer surface at piston circumference two ends, copper supporting ring plays certain guiding and supporting role, prevent that piston packing ring and phenolic aldehyde folder cloth wear ring from wearing and tearing prematurely, occurs pulling phenomenon.
The technical solution of the utility model is: a kind of oil cylinder piston with copper support ring, comprise piston only, on the cylindrical of piston only, be respectively equipped with piston packing ring and phenolic aldehyde folder cloth wear ring, be respectively equipped with the annular groove for copper supporting ring is installed at the two ends of piston only cylindrical; Copper supporting ring is two symmetrical semicircular ring, and copper supporting ring is arranged on respectively in the annular groove at piston only two ends, the smaller external diameter with piston packing ring and phenolic aldehyde folder cloth wear ring of the external diameter of copper supporting ring.
The further technological scheme of the utility model is: copper supporting ring adopts respectively welding manner heap to be welded in the annular groove at piston only two ends, after built-up welding completes, reaches fit dimension required precision by machine tooling.In the time adopting the copper supporting ring of overlaying structure, the opening end of annular groove is processed with horn mouth.
The utility model compared with prior art has following features:
The two ends of piston only have increased respectively copper supporting ring; copper supporting ring plays certain guiding and supporting role; and play the effect of protection piston packing ring and phenolic aldehyde folder cloth wear ring; extend the working life of oil cylinder; prevent oil cylinder piston and cylinder body from pulling and repair difficulty; even scrap, reduced the maintenance cost of oil cylinder.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
