Automotive Hardware Flat Springs are flat spring hardware components used in automotive manufacturing.
Flat springs play a critical role in the car. For example, in the suspension system of an automobile, the flat spring can help absorb the vibration and impact of the road surface and provide a smooth driving experience. They may also appear in the vehicle’s braking system, engine components and various mechanical connections to achieve buffering, support or reset functions.
In the automobile manufacturing industry, the quality and performance requirements for flat springs of automobile hardware are very strict. High-quality flat springs require good elasticity, durability and fatigue resistance to meet the needs of the vehicle under various complex road conditions and use conditions.
Manufacturing process of automobile hardware flat spring mainly includes the following steps:
Winding and forming: use a spring machine to wind the steel wire into the shape of a flat spring. This can be done by cold forming or hot forming processes.
Heat Treatment: Heat treatment of coiled flat springs to improve elasticity and durability. The heat treatment process may include processes such as quenching and tempering.
Strengthening treatment: in order to further improve the performance of flat spring, strengthening treatment can be carried out, such as shot blasting, extrusion, etc.
Surface treatment: the flat spring shall be subject to surface treatment, such as galvanization and phosphating, to improve its corrosion resistance and appearance quality.
In the manufacturing process, the size, precision and performance of the flat spring shall be strictly inspected and controlled to ensure that it meets the relevant standards and requirements.
Flat spring has the following features:
Good elasticity: Flat spring has good elasticity, can withstand large pressure and vibration, while maintaining good recovery performance.
Good conductivity: Flat spring is usually made of metal materials, which have good conductivity and can ensure smooth current transmission.
Corrosion resistance: Flat spring made of metal materials has good corrosion resistance and can be used for a long time in various environments.
Wear resistance: Flat spring has a certain degree of wear resistance, can withstand certain friction and wear, and is not easily damaged.
Easy to process and manufacture: The shape and dimensions of Flat Spring can be customized through precise stamping and machining techniques, making the manufacturing process relatively simple.
Low cost: Compared to other metal springs, Flat spring has a relatively lower cost and is suitable for large-scale production and application.
It should be noted that the specific performance and application of Flat Spring also need to be selected and designed according to specific usage scenarios and requirements.
Flat spring has the following characteristics:
Good elasticity: Flat spring has undergone precise stamping and processing, with good elasticity that can adapt to different pressures and bending degrees, maintaining long-lasting elasticity and conductivity.
Excellent conductivity: Flat spring is made of metal materials and has good conductivity, ensuring stable current transmission.
Corrosion resistance: Flat spring surfaces are usually coated with coatings such as gold or silver to improve their corrosion resistance and wear resistance, thereby extending their service life.
Wide applicability: Flat spring is widely used in battery contacts, circuit board connections, electrical switches, and other fields, and can adapt to different usage scenarios and equipment requirements.
High cost-effectiveness: Compared to other types of shrapnel, Flat Spring has a higher cost-effectiveness, which can meet the needs of most applications while reducing costs
Flat Springs are widely used in industry and play a crucial role in multiple fields due to their unique elasticity and recovery performance. Metal flat spring clips are used in a wide range of applications, such as:
Office supplies: used to fix documents, paper, bills, etc.
Electronic industry: clamp wires and cables and fix electronic components.
Manufacturing: fixing parts and components on production lines.
The working principle of the metal flat spring clamp is mainly based on the elastic deformation of the metal material. When an external force is applied to the spring clamp to make it open, the metal material will undergo elastic deformation and store potential energy. When the external force disappears or decreases, the elastic restoring force of the metal returns the spring clamp to the original closing or clamping state, so as to clamp or fix the object.
Specifically, the working principle includes the following key aspects:
Elastic property of material: metal usually has a certain elastic modulus, which determines the degree of elastic deformation and the ability to restore to the original state when it is stressed.
Shape and structure design: the flat shape and specific bending and curling structure of the spring clamp can produce uniform elastic deformation during stress and provide balanced clamping force during recovery.
Generation of clamping force: when the collet of the spring clamp is stretched, the stress generated inside the clamp will make the collet close quickly after releasing the external force, so as to generate clamping force to clamp the object.
For example, a common dovetail clamp has a spring structure formed by bending the metal sheets on both sides. When the tail of the dovetail clamp is pressed to open, the metal sheet bends and deforms. Once the pressing force is released, the elastic restoring force of the metal sheet makes the jaw of the dovetail clamp tightly closed to clamp the paper and other articles.
For another example, some metal flat spring clips used to fix wires are stretched during installation through special bending and crimping design. After installation, the wires are tightly clamped by the elastic restoring force of the metal to ensure that the wires are fixed in position.
