At present, the standardized products of minshuo die spring mainly refer to Japanese Standard JIS (7 colors: silver, yellow, blue, red, green, Tan, purple); American Standard (4 colors: blue, red, gold, green); ISO international standard (4 colors: green, blue, red, yellow). There are a total of 14 series (see the "product series table" for specific classification); ）Thousands of specifications are available for users.

The mould spring produced by our factory has passed the consummate craft check and the close examination, so that each spring has the good quality guarantee and the ideal service life.

1. Characteristics and advantages of die spring:

1) Spring material: made of high quality chrome vanadium steel (50CrVA), with good fatigue resistance, temperature resistance and toughness.

2) Material entity: it is in the shape of corner and edge of rectangular section, which is different from the general rectangular edge. The spring can reduce the stress concentration at high speed.

3) . strong pressure treatment: the spring is forced for more than three times to eliminate the stress before use, and the spring deformation and fracture will not occur again.

4) Shot Peening: after surface strengthening shot peening, the surface structure of the spring is firm, which improves the strength of stress concentration and prolongs the fatigue life of the spring.

5) Service life: according to the die stroke length, the service life of P1 is more than one million times, P2 is more than 500000 times, and P3 is the limit.

6) . spring frequency: the highest frequency is 1000 times / min, modern mold design, must have high quality mold spring, MSC spring can meet your requirements.

2. Values correctly selected and used:

1) The cost proportion of spring in the mold is very small, but the function is very large. In order to save the cost of a spring, it will waste time and efficiency.

2) The size and load of the die must be considered in the design of the die.

3) When designing the p value of the die, the medium load should be selected as far as possible, and the maximum load should be avoided.

4) When the spring is not suitable for the designed and processed die, the spring can only be re selected, and the inner and outer diameters and two end faces of the spring are not allowed to be ground.

3. Correct installation method:

The installation of die spring is particularly important. In order to achieve the best effect, we must pay attention to two points

1. When the spring is installed in a flat bottom hole without a guide rod, the depth of the hole shall reach at least two turns of the spring. When the spring is installed with a guide rod, the length of the guide rod must be greater than the length of the spring.
