Mold spring production and production
Specifications: Specifications vary from 6-60mm in outer diameter and 10-300mm in length
Main Products: Japanese Material SWOSC-VA Mould Spring, Mickey Nitrogen Spring, Japanese Mickey Japanese Standard, American Standard, Disc Spring, Retaining Spring, Mechanical Spring, Ordered Various Non-standard Springs, Taiwan Drill Chuck, Mould Accessories, mold steel and so on.
Scope of application: This mold spring is suitable for use in metal stamping dies, punch dies, plastic dies, die casting dies, or other reset functions.
Features: The mold spring is specially made for the characteristics of the mold. After strict quality management, each spring is subjected to pressure test. It has special effects on high stress, high speed stamping and heat resistance.
The specifications are divided into seven categories: yellow, blue, red, green, brown, purple, and silver. Customers can choose among them according to their strength.
Material: Mold springs are available from Japan Mickey Co., Ltd. SWOSC-VA Alloy Steel and 50CRVA and 65 Manganese for different customer requirements.
The correct installation and use of mold spring
In general, the most common cause of mold spring problems is often due to improper selection and use of springs.
The percentage of springs in the total cost of the mold is minimal. Trying to save on springs can cause premature spring failures, increase maintenance costs, reduce productivity, waste more time and labor costs, and even damage the mold. And cause greater losses. Therefore, ensuring that the best mold springs are used in every application is a wise investment.
The focus of the design is to determine the type and number of springs before constructing the mold, so that selecting the right spring becomes the design
Part of the job is the best choice.
To allow the springs to load in advance to each spring in the mounting mold, a preload of 5% must be performed in advance to avoid sudden load generation.
Inhomogeneous stress causes loss of spring life.
Do not arbitrarily cut and grind any inner or outer diameter of the grinding spring or reduce the number of turns to match the size of the mold, which can easily lead to damage to the spring and early failure.
The replacement must be replaced at the same time with the same maintenance. Do not replace only one spring. The springs of different lengths and lengths will cause uneven force distribution.
Protection and Maintenance Use under high heat, corrosion, etc. should be protected and mold springs replaced at pre-determined intervals.
Proportional deepening of the guide hole spring installed in the repaired mold should be deepened in proportion to the guide hole, so that the spring device can be stable and produce a uniform and uniform stress.
Proper guidance protection When the free length of the spring is more than four times the average diameter, the spring will deform under compression. To solve
This can be done using sleeves or sleeves, or both, to reduce the potential for spring bending.
Properly long service life Although the mold spring design allows maximum stress, the mold spring does not work at maximum load.
It is expected that it will maintain its maximum working life.
Correct installation method
In order to obtain the best use of performance, the following two points must be observed when installing the spring:
When installing in a flat bottom hole without a guide, the depth of the guide hole must be at least two turns deep
When installed in a guide, the length of the guide must be greater than the length of the spring
