Abstract
The utility model belongs to the technical field of the piston in the pneumatic cylinder is cuted to square billet continuous casting hydraulic pressure clipper. The piston comprises a piston body and a piston rod, wherein the piston body is connected with the rod into a whole, and a wear-resistant material layer is arranged on the surface of the working excircle of the piston body. The utility model discloses owing to compound wear-resisting material on the piston body, practiced thrift noble metal 90%, reduce the hydro-cylinder body hole degree of depth 80-120mm, reduced the wearing and tearing to hydro-cylinder internal surface simultaneously, prolonged life, guaranteed hydraulic cylinder use reliability.
Description
The utility model belongs to the piston technical field in the billet continuous casting hydraulic shearer shearing oil hydraulic cylinder.
Existing hydraulic shearer is sheared the piston that uses in the oil cylinder, and two kinds of structures are arranged: a kind of is that piston body and piston rod are made split, piston body material bronze, piston rod material steel, and piston body and piston rod are fixedly connected with nut or flange; Another kind is a piston with rod, all adopts steel to make.The former will consume a large amount of non-ferrous metals, needs certain axial length space when piston body is connected with bar simultaneously, has increased the axial dimension of cylinder body, strengthens the working depth of cylinder inner bore.The latter easily causes cylinder body to damage in early days owing to the piston body working surface with hard contact of inner surface of cylinder block, the using effect extreme difference.
The purpose of this utility model is to provide a kind of above-mentioned defective that overcomes, and can save precious metal, can guarantee that again oil hydraulic cylinder is difficult for the piston in the early stage cutting machine oil hydraulic cylinder that damages.
Now be described in detail the technical solution of the utility model:
The utility model comprises piston body and piston rod two parts, and piston body and bar fuse, and the pistons work outer round surface is provided with wear-resistant material layer.
The wearing layer of pistons work outer round surface is built-up welding or a spraying abrasion-proof copper on cylindrical, or antifriction material.
Radially have groove on the outside piston.
The utility model has the advantages that: owing to adopted composite abrasion resistance material on the piston with rod body, piston body can use general steel, saved precious metal 90%, reduce cylinder body hole depth 80～120mm, wearing and tearing have been reduced simultaneously to oil cylinder inner surface, prolong working life, guaranteed the operational safety of hydraulic jack.
Accompanying drawing is a structural representation of the present utility model.
1 is piston rod among the figure, the 2nd, and piston body, the 3rd, antifriction material.
Introduce embodiment in conjunction with the accompanying drawings:
As shown in the figure, the utility model comprises piston body and piston rod, piston body and piston rod are linked as an integral body, the piston body part adopts carbon steel or low-alloy structural steel, radially has the groove of certain width on the piston body cylindrical, to increase the adhesive strength between composite material and the piston body, the outer garden of piston body work surface recombination one deck has certain thickness wear-resisting copper layer, or other antifriction material layers, and then reaches usage requirement through fine finishing.
Claims (3)
1, the piston in a kind of cutting machine oil hydraulic cylinder, it comprises piston body and piston rod, and piston body and bar fuse, and it is characterized in that, and piston body work outer round surface is provided with wear-resistant material layer.
2, the wearing layer that it is characterized in that piston body work outer round surface according to the piston in the described cutting machine oil hydraulic cylinder of claim 1 is built-up welding or spraying abrasion-proof copper or an antifriction material on cylindrical.
3, according to the piston in the described cutting machine oil hydraulic cylinder of claim 1, it is characterized in that, radially have groove on the piston body cylindrical.
