Function introduction of shrapnel

2022-12-06

Main functions of spring stainless steel spring:

1. Control the movement of machinery, such as valve shrapnel in internal combustion engine, control shrapnel in clutch, etc.

2. Absorb vibration and impact energy, such as buffer shrapnel under cars and trains, vibration absorbing shrapnel in couplings, etc.

3. Store and output energy as power, such as watch shrapnel, shrapnel in guns, etc.

4. It is used as a force measuring element, such as a force measuring device, a spring in a spring scale, etc. The ratio of load and deformation of the shrapnel is called the shrapnel stiffness. The greater the stiffness, the harder the shrapnel is. According to the mechanical properties, shrapnel can be divided into tensile shrapnel, compression shrapnel, torsional shrapnel and bending shrapnel, and according to the shape, it can be divided into dished shrapnel, annular shrapnel, plate shrapnel, spiral shrapnel, truncated cone scroll shrapnel and torsion bar shrapnel. The ordinary cylindrical spring fragments are widely used because of their simple manufacture, various types can be made according to the loading conditions and simple structure.

Generally speaking, the manufacturing materials of shrapnel shall have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Carbon shrapnel steel, alloy shrapnel steel, stainless steel shrapnel, copper alloy, nickel alloy and rubber are commonly used. The manufacturing methods of shrapnel include cold coiling method and hot coiling method. The cold coiling method is generally used for the spring wire with a diameter of less than 8 mm, and the hot coiling method is used for the spring wire with a diameter of more than 8 mm. Some shrapnel will be subjected to strong pressure or shot peening after being made, which can improve the bearing capacity of the shrapnel.

The shrapnel is an elastic element widely used in the mechanical and electronic industries. The stainless steel shrapnel can produce large elastic deformation when it is loaded, transforming mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the shrapnel disappears and returns to its original state, transforming deformation energy into mechanical work or kinetic energy.

5. How to make good quality stainless steel shrapnel?

(1). The customer wants to find an etching factory with complete qualifications. Only qualified etching plants, corresponding equipment, including etching equipment, pre-treatment oil removal and dust removal equipment, roller coating equipment, exposure pattern transfer equipment, development equipment, etching processing equipment, anime imager equipment, dust-free clean room, and professional operators are very important.

(2). Is the system complete? Don’t think of ISO9001 and ISO14001 as a decoration. A factory that truly meets the 7S standard will always be a standard and tidy factory. As customers often tell us: a standardized and tidy factory, I believe that the products will not be worse.

(3). Is customer service complete? Serving customers means helping customers, and serving customers means helping customers solve problems. Actively provide various solutions, and the business personnel take the initiative to propose solutions to problems, which is a major element to gain customer trust. Don’t just nod and say yes. Proactive discovery and prevention of problems are the most fundamental elements to do a good job in related products!

(4). Are the details in place? Details determine success or failure! For the etched products, we should ensure the accuracy of every detail and every key dimension, and ensure that they meet the requirements of the customer’s engineering drawings.

(5). The stability of suppliers is also an important link to ensure the quality of etching processing. The stability of material quality is the premise of good product processing. Yaodafa’s precise material purchasing channels are all directly supplied by regular and large steel rolling plants. The materials are stable, and the environmental protection standards are up to standard. Don’t make a big failure to save small costs!
