Stainless Steel Shaft

The air-expansion shaft is very convenient and quick to use. It only needs to be self-contained. The air pressure is controlled within the range of 6-8kg/cm2. When the external components (such as a round paper tube) need to be locked, as long as the air gun pair The air nozzle on the inflatable shaft can be inflated to withstand the external parts (such as a circular paper tube). When you want to loosen the paper discharge, press the sliding outer part of the air nozzle (such as a circle). The paper tube can be removed. The following describes its technical features:

The metal frame of the inflatable shaft is dug out of a box-type window at the fixed end of the operating side of the cantilever mandrel 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. The precision ball screw drive, the moving position of the air shaft is on the center line of the plate mandrel, and the linear guides are respectively installed at the upper and lower ends of the box window to fix the moving steel block, thereby ensuring the printing platform is running at high speed. Stable. In this design, the fixing of the mandrel is completely automatic, and the movement of the entire screw and the locking of the shaft end eliminate the human factor. The moving steel block is fixed to the frame by two upper and lower linear guide rails, and since the screw rod 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 are both effective. At the center of the plate mandrel, only a small partial pressure is formed, and since the force load acts only on the center of the plate mandrel, there is no torque on the support frame.

Because the weight of the air bearing shaft can be large and the use time is long, what are the misunderstandings in the performance judgment of the air shaft?
1. Customized production specifications and standard specifications have performance limitations and cannot be the performance criteria;
2, can not judge the performance of the application from the corresponding application;
3, the damage of the inflatable shaft can not be attributed to the performance of the inflatable shaft, and many reasons will be damaged;
4, the parameters are generally reference objects, for the main sports components such as airbags can withstand the nominal parameters and actual parameters need to be treated correctly according to the actual situation.
The performance judgment error of the inflation shaft has the above points, such as the air pressure of the airbag, and the performance caused by too large or too small can not be used as a basis for judging the performance.

The inflation shaft needs to be checked for basic conditions after purchase, and has a preliminary understanding of the machine and introduces its basic inspection items:
1. Whether the movable parts of the inflation shaft device are free to move. Whether the stop position of the movable part is appropriate.
2. Whether the mechanical, hydraulic and pneumatic components of the air shaft device are ready for installation. Whether the working conditions of the equipment have met the requirements of the operation.
3. Whether the various detection switches and sensors of the air shaft device can reliably send letters. Is the position adjustment appropriate? Has it been installed and fixed reliably?
The basic inspection of the air-expansion shaft includes movable parts, hydraulic pressure and various switches. The functions of these parts must also be initially understood to facilitate later use.
