What role does the guide pillar play during mold production?

There are two main functions, namely guidance and support. The former is to guide the upper mold and the lower mold to align in the correct position. The common problem is that there is no guide pillar guide sleeve. In addition, there can also be some support for the upper membrane column. Considering that the sliding fit between the guide pillar and the guide sleeve is relatively frequent, it is necessary to provide better lubrication performance and open a lubricating oil groove. In order to ensure the working strength of the guide pillar, the diameter of the fixed position should be about twice the diameter of its working position.

Function and processing technology of piston rod

Piston rods can be used in hydraulic and pneumatic systems, and their processing requirements are relatively high. Therefore, the quality of hydraulic cylinders is mostly affected by the quality of the piston rods. They can be used in hydraulic and pneumatic systems, and their processing requirements are relatively high. Therefore, the quality of hydraulic cylinders is mostly affected by the quality of the piston rods.

Overview and Tips for Using Piston Rods

The piston rod is a connecting component that supports the piston to do work, and is mostly used in the moving parts of air cylinders and oil cylinders. It is a frequently moving and highly skilled moving component. The processing quality directly affects the life and reliability of the entire product. The machining requirements for piston rod are high, and the requirements for phase coaxiality and wear resistance are strict.

Precautions for Material Selection of Gear Reducer Gears

Gear transmission transmits motion and power between any two shafts in space through the meshing of teeth, and can change the form and speed of motion. Gear transmission has a wide range of applications, constant transmission ratio, high efficiency, and long service life. In the design and manufacturing process of mechanical parts, it is not only necessary to consider that the performance of the material can adapt to the working conditions of the part, making the part durable, but also requires that the material have good processing performance and economy, in order to improve the productivity of the part, reduce costs, and reduce consumption. If the gear material is improperly selected, premature damage or even failure of the parts can occur. Therefore, we should be cautious in selecting gear materials.
