The working parts and appearance quality of the stamping die are closely related to the wear resistance, crack resistance and adhesion of the die, which directly affect the service life of the die. In particular, the size of the surface roughness has a great influence on the service life of the mold. The wear problem of stamping dies is a problem that every stamping parts manufacturer must face, so how to solve this problem? Yiwei Precision has summarized years of production experience and found that the following

Nitrogen gas springs: Nitrogen gas springs for molds (referred to as die nitrogen springs or nitrogen springs or nitrogen cylinders or nitrogen cylinders) are a new type of high-pressure nitrogen as the working medium Elastic components, which are small in size, large in elasticity, long in stroke, stable in operation, precise in manufacturing, long in service life (one million times), flat in elastic curve, and do not require preloading, etc. It has metal springs, rubber and air cushions, etc. It is difficult to c

As we all know, the gas source of the nitrogen spring is nitrogen, but I wonder if you have thought about why the nitrogen spring should choose nitrogen as the gas source instead of other common gases? The nitrogen gas spring is designed according to the compressibility principle of gas. The nitrogen spring cylinder is filled with a gas to obtain the elastic pressure. The reason for choosing the nitrogen gas spring as the origin of the work has sorted out the following three points for you: 1. First of all, as t

Lubrication overview: With the development of CNC machine tool technology, the ball screw pair is also becoming more and more high-speed. High-speed ball screws face problems such as noise, vibration and temperature rise caused by friction. If there is no good lubrication, the friction of rolling parts will increase, which is the main reason for shortening the life. In order to properly lubricate the high-speed ball screw pair, the operating load, speed, accuracy, environment and power of the ball screw are impo

The mold nitrogen gas spring is an elastic component with high pressure nitrogen as the working medium, which requires customers to install and use it correctly to ensure its safety, reliability, expected use effect and ideal service life. The following content, the editor of Shiruida has sorted out some precautions for the use of nitrogen gas springs: Precautions for the use of mold gas springs 1. Ensure that the workpiece pressed against the upper end of the piston rod of the nitrogen gas spring of the mold
