Abstract
The utility model relates to a double-metal piston for pneumatic mechanisms, which is characterized in that the piston is composed of a piston disk and a piston shaft which are closely combined together. The piston disk is a component made of aluminium. The piston shaft is a component made of steels. The position of the piston shaft inserted in the piston disk is provided with annular steps. The utility model has the advantages of light weight, high reliability, low processing cost and high productivity.
Description
The utility model relates to the pneumatic mechanism piston, and a kind of pneumatic mechanism piston made from bimetal is provided especially.
Being used for the cylinder to-and-fro motion of the piston of pneumatic mechanism at pneumatic mechanism, playing transferring power, is the critical component in the mechanism, and piston is divided into two-part: 1. piston plate; 2. piston shaft.Two-part of initial piston all are to make with the 45# steel, weld together then, and its shortcoming is: 1. weight is big, and transmission performance is poor; 2. with the serious wear of steel cylinder body, cylinder body is damaged.After change aluminum piston dish and steel piston shaft into, piston plate processes with aluminium bar or aluminium sheet, middle threading, with the steel piston shaft by scyewed joint as a whole.This design alleviates 50% than former design weight, but shortcoming be piston in to-and-fro motion, thread looseness and wearing and tearing descend linking intensity and reliability greatly.
The purpose of this utility model is to provide a kind of pneumatic mechanism bimetal piston, and it is in light weight, the reliability height, and processing cost is low, the productivity height.
The utility model provides a kind of pneumatic mechanism bimetal piston, it is characterized in that: this piston is made of piston plate that is closely linked (1) and piston shaft (2), and piston plate (1) is an aluminium matter part, and piston shaft (2) is a steel spare.The position that is embedded on the piston shaft in the utility model (1) in the piston plate (2) is equipped with circular step (11).
The utility model piston, piston plate are aluminium tree material, and piston shaft still is a steel material, and the two is compound by Extrution casting technique, and overall time casts out.
The utlity model has following characteristics: 1. this part adopts extrusion casting method, whole casting together, make between aluminium piston plate and the steel axle combine effective, the adhesive strength height, this is because compound under the pressure, can significantly improve the filling of aluminium liquid, strengthen the interlocking between the two, also can make between the bimetal to contact closely, and increase mechanism's clamping action, can improve the wellability of liquid metal again the solid-liquid surface, the temperature of rapid rising solid metallic surface, thereby increase the seam effect, the piston of this structure significantly improves than the piston reliability of welding and spiral marking connection, and practical effect is good.2. when casting,, reduce cost, improve the transmission performance of product by the further weight reduction of stiffening rib is set.3. reduce corresponding machining amount, enhance productivity.
Below by accompanying drawing in detail the utility model is described in detail in conjunction with the embodiments.
Accompanying drawing 1 is the bimetal piston structural representation.
Embodiment
As shown in Figure 1, the pneumatic mechanism bimetal piston is made of piston plate that is closely linked (1) and piston shaft (2), and piston plate (1) is an aluminium matter part, piston shaft (2) is a steel spare, and the position that is embedded on the piston shaft (1) in the piston plate (2) is equipped with circular step (11).
Claims (2)
1. pneumatic mechanism bimetal piston is characterized in that: this piston is made of piston plate that is closely linked (1) and piston shaft (2), and piston plate (1) is an aluminium matter part, and piston shaft (2) is a steel spare.
2. according to the described pneumatic mechanism bimetal piston of claim 1, it is characterized in that: the position that is embedded on the piston shaft (1) in the piston plate (2) is equipped with circular step (11).
