The stamping process of iron frame aluminum alloy folding table plays an extremely critical role in its production process, directly affecting the molding quality of the parts and the performance and quality of the final product.
First of all, in the design of the stamping die, it is necessary to fully consider the shape, dimensional accuracy requirements and material properties of the iron frame and aluminum alloy parts. For the iron frame part, the die should be able to adapt to the strength and toughness of the steel, and design a reasonable blanking gap to ensure that the edges of the iron frame parts are neat, burr-free, and accurate in shape during the stamping process. For example, the stamping die of the table leg should accurately shape its curvature and the shape of the connection part so that it can be assembled smoothly with other parts later. For parts such as aluminum alloy desktops, the mold design should take into account the ductility of aluminum alloy, and adopt a suitable demoulding angle and stamping speed to prevent the aluminum alloy surface from being scratched or deformed. Through computer-aided design (CAD) and simulation analysis technology, the mold structure can be optimized in advance, and possible molding defects such as cracking and wrinkling can be predicted, thereby providing a reliable basis for actual production.
Secondly, the selection and pretreatment of stamping materials are crucial to the molding quality. For the iron frame, it is necessary to select steel with stable quality, uniform thickness and meeting the design strength requirements, and carry out necessary rust removal and leveling before stamping to ensure that the surface of the material is flat and free of impurities, so that the stamping process can proceed smoothly and reduce the forming errors caused by material problems. For aluminum alloy materials, it is necessary to pay attention to its alloy composition and hardness, and choose the appropriate heat treatment state to obtain good stamping performance. Before stamping, the aluminum alloy sheet is cleaned and lubricated to reduce the friction during the stamping process, which helps to improve the surface quality and dimensional accuracy of the parts, such as making the surface of the aluminum alloy desktop smooth, scratch-free, and flatness meet the standards after stamping.
Furthermore, the control of stamping process parameters is the core of ensuring the forming quality. Parameters such as stamping speed, pressure, and stroke need to be accurately set according to the requirements of different components. For example, when stamping the connection part of the iron frame, a large pressure is required to ensure a firm connection, but it should not be too large to cause excessive deformation or rupture of the material. For the forming of the aluminum alloy desktop, the stamping speed should be controlled to avoid too fast impact marks and affect the appearance quality. At the same time, during the stamping process, the changes in process parameters should be monitored in real time and adjusted in time to ensure that each batch of parts can meet the same molding quality standards and ensure the overall stability and reliability of the iron frame aluminum alloy folding table.
Finally, quality inspection and correction after stamping are indispensable. Use advanced testing equipment, such as three-coordinate measuring machines, to conduct comprehensive inspections on stamped parts, including dimensional accuracy, shape tolerance, surface quality, etc. For unqualified parts detected, analysis should be carried out and corresponding corrective measures should be taken, such as correcting slightly deformed parts through the shape correction process, and for parts with serious defects, they should be scrapped or re-stamped. Only by strictly controlling the quality inspection link after stamping can we ensure that the final assembled iron frame aluminum alloy folding table is of high quality and meets market demand and consumer expectations.
