Talk about the principle of spring distribution

Spring distribution principle:
1. When the springs are arranged in a row, make sure that the distance between the center of the spring through hole and the edge of the template is greater than the outside diameter D, and the distance between the spring and the other through holes is more than 5 mm.

2. The arrangement of springs first considers the stressed parts, and then considers that the entire mold is balanced and stable. The key parts of the stress are: the inner stripper shape of the composite mold and the periphery of the punch; the punch around the punching die; the bent edge of the forming die and the place where the teeth are formed.

3. The spring should be evenly distributed around the inner guide pillar to ensure the normal movement of the mold.

China's spring standardization work began in the early 60s and has been 40 years old. It has formed a relatively complete standard system. At present, there are 22 national standards for springs and 30 industry standards. In 1999, the AQSIQ approved the establishment of the National Spring Standardization Technical Committee (SAC/TC235), and the spring standardization work was fully promoted. In 2004, ISO/TC 227 (spring) was established internationally and China participated as a member. This marked that China's spring standardization work has entered a new stage, that is, to fully track and substantively participate in the work phase.

The special-shaped spring has the characteristics of small volume, large load, convenient combination and the like, and also has the advantage of concentrated transmission of load. A variety of different curves can be obtained by means of single-piece combination, multi-piece combination and mixed combination.

The replacement of cylindrical coil springs in a wide range of mechanical industries reflects the miniaturization and versatility of the new product (mainframe) design. For example, in the direction of the load, smaller deformations can withstand larger loads and the axial space is compact.

Compared with other types of springs, its deformation energy per unit volume is larger, and it has better shock absorption capacity. In particular, the use of superimposed combinations, the effect of absorbing shocks and dissipating energy is even more pronounced due to surface frictional damping. At present, it is widely used in such industries as defense, metallurgy, engineering, electric power, machine tools, and construction.
