Abstract
The invention relates to a train brake cylinder piston which comprises a piston cap and a piston rod, wherein the piston cap is of a cylinder shape with one open end and one sealed end; the piston rod is tubular, and the length of the piston rod is greater than the depth of the inner cavity of the piston cap. The train brake cylinder piston is characterized in that one end of the piston rod is fixedly arranged on the end surface of the inner cavity of the piston cap by virtue of a welding method, and the piston rod and the piston cap are concentrically arranged. The piston is low in processing difficulty, simple in processing step, relatively high in production efficiency and relatively low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of retainer, is retainer cylinder piston specifically.
Background technique
Train brake is exactly the motion preventing train artificially, comprises and makes its slow down, not accelerate or out of service.The train braked or locomotive are removed or weakened its braking action, is then called " alleviation ".The equipment set installed aboard for apply brake and alleviation, is generically and collectively referred to as retainer.Critical piece retainer being used for realize braking and mitigation capability is exactly cylinder.
Traditional retainer cylinder piston comprises piston cap and piston rod, the cylindrical shape that described piston cap is one end open, one end is closed, and described piston rod is tubulose, and the length of piston rod is greater than the depth of inner cavity of piston cap; One end of piston rod is connected in one with the intracavity bottom of piston cap, and piston rod and piston cap are arranged concentric.Manufacture this retainer cylinder piston, first must utilize casting or Forging Technology, make corresponding foundry goods or forging, and then the fine finishing such as cutting are carried out to this foundry goods or forging, just can process the integrative-structure of piston cap and piston rod, its difficulty of processing is large, process step is complicated, and manufacturing efficiency is lower.In addition, adopt the technique of casting or forging, carrying out cutting, casting and forging process need to use a large amount of raw material, and cutting can produce a large amount of waste wood, can improve the manufacture cost of this piston like this.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of retainer cylinder piston, and the difficulty of processing of this piston is little, process step simple, and manufacturing efficiency is higher, and manufacture cost is relatively low.
For solving the problem, take following technological scheme:
Retainer cylinder piston of the present invention comprises piston cap and piston rod, and the cylindrical shape that described piston cap is one end open, one end is closed, described piston rod is tubulose, and the length of piston rod is greater than the depth of inner cavity of piston cap.Be characterized in that one end of described piston rod is fixed on the interior resonator end surface of described piston cap by the mode of welding, and piston rod and piston cap are arranged concentric.
Wherein, described piston cap is integrally formed by connecting with one heart by the first cylindrical shell and the second cylindrical shell, the internal diameter of the first cylindrical shell is greater than the internal diameter of the second cylindrical shell, the opening end of the first cylindrical shell there is the circular fold of outside 90 degree, center hole is arranged at the bottom of the first cylindrical shell, and this center hole is connected with the opening end of the second cylindrical shell; Described piston rod is fixed on the interior resonator end surface of the second cylindrical shell by the mode of welding with the connecting end of piston cap.
Take such scheme, have the following advantages:
Because one end of the piston rod of retainer cylinder piston of the present invention to be fixed in piston cap on resonator end surface by the mode of welding.Therefore, can adopt the mode of pressure rolling that steel plate Direct Rolling is become the shape of piston cap, piston rod is fixed on the corresponding position of piston cap by the mode of recycling welding, namely can be made into this retainer cylinder piston.With casting of the prior art or forging, carry out cutting again technique compared with, its difficulty of processing is little, and process step is very simple, effectively can improve the manufacturing efficiency of this piston.In addition, adopt the processing technology of rolling and welding, waste wood raw material a large amount of in casting or forging process can avoided to drop into and produce in working angles, greatly reduces the raw material usage of course of working, the manufacture cost of this piston is reduced.
