What are the fundamental requirements for the upholstery hardware foot stamping process?

 

It can be asserted that hardware stamping components are extensively utilized in both the industrial sector and in everyday life.

 

We are all aware that metal stamping is a fabrication technique that employs a stamping press and dies to forge materials through pressing.

 

It boasts the advantages of convenient operation, high precision in stamping, and ease of mechanization and automation, making it the most prevalent manufacturing method currently in use.

 

Basic Process Requirements for Sofa Hardware Foot Stamping:

Material Specification: The materials used for metal stamping components must meet not only the technical demands of product design but also the requirements of the stamping process itself and post-stamp processing such as cutting, electroplating, and welding.

 

Design Prudence: When designing the structural shape of sofa feet, it is advisable to opt for simple and rational surfaces (such as planes, cylindrical surfaces, and spiral surfaces) and their combinations. Additionally, the number of processed surfaces and the area subjected to processing should be minimized.

 

Blank Preparation: Select a rational method for blank preparation in mechanical manufacturing, which may include the direct use of profiles, castings, forgings, stampings, and weldments. The choice of blanks is related to specific production technical conditions and generally depends on production batch size, material properties, and the possibilities for processing.

 

Forming Performance Demands: For the forming process, materials should possess good plasticity, a small yield strength ratio, a large plate thickness directional coefficient, a small plate plane directional coefficient, and a small ratio of the material's yield strength to its elastic modulus to facilitate stamping deformation and enhance part quality.

 

For the separation process, materials need not have high plasticity but should maintain a certain degree of ductility; the higher the material's plasticity, the more challenging it is to achieve separation.

 

Precision and Cost Determination: Specify the appropriate manufacturing precision and surface roughness to control part processing costs. The cost of processing sofa hardware foot stamping parts will increase with enhanced precision, especially in cases requiring high accuracy, where the increase is particularly significant. Therefore, high precision should not be pursued without adequate justification. Similarly, the surface roughness of metal stamping parts should be determined based on the actual needs of the mating surfaces.

 

The processing technology of sofa hardware foot stamping parts is relatively intricate. To ensure that the performance of these parts meets usage requirements, it is necessary to adhere to the corresponding process requirements to ensure the feasibility of production.

 

Basic Conditions for Sofa Hardware Foot Stamping Parts:

Material Conservation: Metal stamping parts are manufactured through stamping with minimal material consumption. The parts are lightweight and possess just the right hardness. After the sheet material undergoes plastic deformation, the internal structure of the metal is improved, thereby increasing the strength of the stamping parts.

 

Dimensional Accuracy: Metal stamping parts exhibit high dimensional precision, uniformity in dimensions among parts from the same mold, and good interchangeability. No further machining is needed to meet general assembly and usage requirements.

 

Surface Integrity: During the stamping process, as the material's surface remains undamaged, the surface quality is unaffected, resulting in a smooth and aesthetically pleasing appearance. This provides favorable conditions for surface treatments such as painting, electroplating, and phosphating.

 

Advantages of Sofa Hardware Foot Stamping Parts:

Quality Consistency: During metal stamping, molds ensure the dimensional and shape accuracy of the parts, typically without compromising the surface quality. With a generally longer mold lifespan, the quality of metal stamping is reliable.

 

Complexity in Design: Metal stamping can produce parts with exquisite designs and complex shapes, including large-sized components like rivets, cap nails, sofa legs, and even larger automotive parts and covers.

 

Interchangeability: Metal stamping parts have high dimensional accuracy and uniform size among parts from the same mold, ensuring good interchangeability without the need for further machining for general assembly and use.

 

Production Efficiency: Metal stamping processing boasts high production efficiency, easy operation, and is easily mechanized and automated. This is due to the reliance on stamping dies and equipment, with ordinary presses capable of dozens of strokes per minute and high-speed presses reaching hundreds or even thousands of strokes per minute.

 

Strength with Lightness: Manufactured through stamping with minimal material consumption, the parts are lightweight with just the right hardness. The plastic deformation of the sheet material improves the metal's internal structure, enhancing the strength of the stamping parts.

 

Aesthetic Surface Finish: The undamaged surface quality post-stamping ensures a good surface finish that is smooth and visually appealing, providing convenient conditions for various surface treatments.
