Cantilever expandable Shaft

The metal frame of the cantilever expansion shaft excavates a box-type window at the fixed end of the cantilever mandrel operating side to ensure the structural rigidity of the printing platform. The bearing seat is mounted on the inside of the movable steel block, and the steel block is High-precision ball screw drive, the moving position of the screw is on the center line of the plate mandrel, and linear guides are respectively installed at the upper and lower ends of the box window to fix the moving steel block, thus ensuring the stability of the printing platform in high-speed operation. . In this case, since the screw moves on the center line of the plate roller mandrel, the thrust of the center impression cylinder against the plate roller and the driving force along the direction of the ball screw act on the center of the plate roller mandrel, and there is no torque on the support frame. .

At present, there are more and more applications of the air-expansion shaft in the industrial manufacturing process. Volkswagen is gradually getting to know this product. Specifically, this part protrudes to form the shaft after the relevant gas pressure. Once this part is not available, The pressure, the component quickly retracted, because of its type of product characteristics, many applications have given it a variety of such as the reel, the expansion axis.
 
The working principle of the air-expansion shaft is particularly simple. When the gas is aligned with the air nozzle of the shaft, the parts will have a working effect. When the sliding vent switch of the air nozzle is pressed, the key strip will change back to the original shape, and In normal work, the advantage of the inflation shaft is also very significant. First, during the inflation period, the separation between the aeration nozzle and the gas-strength device is rapid, and the gas pressure can be changed within three seconds.
 
In addition, in terms of carrying capacity, such shafts can be controlled to a certain extent. According to the actual production load requirements, the shaft diameter will be determined to a certain extent, and the material of the shaft itself can withstand a certain degree of pressure and load. of.
 
As a component commonly used in production machinery, the air-expansion shaft plays a vital role. It uses high-pressure gas to fill the shaft to achieve the function of the shaft. It is widely used in the mechanical equipment of the printing industry because of the winding characteristics of such shafts. The air pressure has a great relationship. In mechanical production, its name is also inseparable from the gas. The inflation shaft is often called the inflation shaft and the inflation shaft.
 
The wide application of this type of inflation shaft has a great relationship with the performance of its products. First of all, the inflation process of such shafts is short, the operation and application are convenient, and whether the shaft body and other parts fit completely depends on the injection of high pressure gas. In addition, in terms of the load bearing range of the shaft, its variability is very large, and it is suitable for applications in many occasions.
 
The important point is that when the air-expansion shaft components work, it is very efficient, and it is suitable for economical products in the printing industry, so as to further broaden the application range of the products, and it is very important in the various mechanical production. effect.
