In the process of using the rolling tube, the work performance, the use range, the construction precision, the appearance, the material and the test method are constantly put forward new requirements, so the development and progress of the rolling pipe are constantly promoted. For example, the use of loaders, bulldozers and compactors in construction machinery.
Characteristics of thin wall rolling tube
The thin wall rolling pipe can be divided into two categories in a certain degree, one is to do the reciprocating linear motion in the work, and also to do the reciprocating swing. In the process of the work of the thin-walled rolling pipe, to a certain extent, the piston is lubricated by the oil mist in the compressed air, as a pressure energy of the compressed gas. Pneumatic actuators for converting mechanical energy into thin walled tubes are widely applied in modern industry.
Classification of thin-walled rolling tubes
First of all, there are still single acting, double acting, diaphragm type and impact type parts for thin walled rolling pipe that keeps the linear motion state at work. From the analysis of composition, the main components include cylinder, end cap, piston, piston rod and seal.
The so-called single action thin-walled rolling pipe, mainly refers to a piston rod only at one end, so during the working period, the air pressure is produced by the gas supply at the side of the piston. In the air pressure, the piston reaches out, and then returns under the effect of spring or self weight.
While the double acting thin wall rolling pipe can be supplied alternately by the two sides of the piston, so that it can output force in one or two directions. For diaphragm thin-walled rolling tubes, they do not contain a piston inside, instead of a diaphragm, which usually only can output force from one direction and reposition with a spring. It has good sealing performance, but it has short travel.
Besides, the impact thin wall rolling pipe is actually a new type of executive element. In practical applications, it can convert the pressure energy of compressed gas into the kinetic energy of piston at high speed (usually 10~20 meters per second), so as to do work.
In addition, there is also a rod less thin-walled rolling pipe, which does not contain piston rod. The thin-walled rolling tube that does the reciprocating swing can also be called the oscillating thin wall rolling tube, which is divided into two by the blade, alternately supplying air to the two cavity, and the output axis is swinging, and the swing angle is less than 280 degrees.http://www.ht-tube.com/
