Key Control Points in Aluminum Plate Forming and Stamping Mold Design
2.1 Key Points for Designing Extrusion and Forming Molds
Due to the far inferior forming properties of aluminum sheets compared to steel plates., Low elongation, poor plasticity, soft material, and low elastic modulus in aluminum plates., Therefore, during the design process of molding molds, the following points mainly need to be considered::The elongation of aluminum sheets is less than that of steel sheets., Allowable deformation is less than steel plate., Therefore, aluminum sheets are more prone to cracking., Please provide the Chinese content to be translated.RThe corner and draft angles should be slightly larger than the steel plate., Eliminate the phenomenon of cracking in product design and development. Aluminum plates have poor plasticity., During the stamping process, the steel plate is more prone to wrinkling., For deeply drawn parts, Maximize the inclusion of crease bosses or convex ribs on the side wall of the product., Addressed the issue of creases in the product from the process design aspect. Aluminum sheet material is softer than steel plate., Therefore, the surface roughness requirements for molding molds are quite high., Surface chrome plating is recommended for all moldings of forming types., Enhancing product quality through the design and development of industrial apparel. The elastic modulus of aluminum plates is lower than that of steel plates., Only steel plates1/3, The springback of aluminum plates is greater than that of steel plates.3No Chinese content provided, please provide the news content to be translated., Controlling the springback of aluminum sheet forming is therefore particularly important.
Key Points for Designing Repair and Refurbishing Molds
Aluminum sheets are valued for their lightweight and soft properties., During the production of trimming die molds, aluminum shavings are often generated., Uncontrolled pressure can cause surface indentation on parts., Product appearance quality defects were caused. For aluminum shavings, optimization treatment can be carried out on them with the assistance of process and mold auxiliary devices. In the process, the angle of trimming and punching should be designed as small as possible during the design phase., "Optimize the use of positive piercing processes.", AvailableNo Chinese content provided.

Key Control Points in Aluminum Plate Stamping Production
3.1 Raw Material Storage
Currently, most vehicle manufacturers still use aluminum sheets and primarily procure and deliver them in the form of sheet materials. The major aluminum sheet producers are still predominantly foreign-based., The logistics delivery cycle is longer., Aluminum sheets have a shorter时效性., EasyMold occurrence, Therefore, stringent requirements must be imposed on the preservation of materials at this stage., The entire production and transportation process of aluminum plates must ensure strict waterproofing and moisture resistance., To prevent mold from affecting normal production due to moisture damage.
3.2 Unstacking Sheets
During the automated production process of aluminum sheets, Due to the inherent non-magnetic properties of the aluminum sheet material., The technical challenge lies in the process of separating stacked aluminum sheets during production. The issue of aluminum sheet separation not only leads to downtime in stamping production, but also significantly impacts production efficiency., In severe cases, it can lead to double molding, resulting in serious production accidents and damage to molds., The incident has resulted in significant economic losses for the company. As we progressively advance the automation of aluminum sheet production., How to address the issue of aluminum sheet separation has become a key research focus. There are various different methods for the current process of separating aluminum sheets., One of the more common methods is the blow-off splitting device., But as aluminum plates find extensive applications in an increasing number of fields, Press machine suppliers can equip their newly designed automated stamping production lines with blowing separation devices., The company has integrated aluminum plate splitting into the automated production line., Achieve automatic and rapid splitting of aluminum plates. However, during the splitting process of aluminum plates on an automated production line, if a blowing separation device is used..., Select blow mode and pressure values accurately and effectively., Only by meeting the requirements can the splitting effect of the aluminum sheets be guaranteed., Otherwise, the anticipated aluminum sheet separation goals cannot be achieved.
3.3 Component Automation Production
As science and technology continue to evolve and advance, At present, the performance of aluminum plate materials is continuously being updated., But when compared to the forming properties of steel plates,, Aluminum sheet forming performance is relatively low., This also makes the stamping and forming process of aluminum plate materials, as well as the design and selection of the forming molds, a crucial part of the process., The requirements must be continually elevated, with the surface lubrication performance of the materials themselves being crucial as well., But the current surface lubrication process employs dry lubrication technology., Compared to oil lubrication, it can effectively enhance the forming performance of aluminum plate materials. The forming mold must ensure good forming processability., The mold's flange fitting rate must be achieved.90%The above, And the edge trim and mold surfaces must be smooth., Chrome plating can enhance the surface finish of molds. Aluminum sheet forming also demands a high level of control over the equipment's pressure edge force output. If it's a single-action press machine..., Avoid using cushion forming equipment as much as possible., Utilize a CNC hydraulic pad with more stable pressure control or a servo motor-controlled pad. Aluminum shavings are produced during the forming or trimming process of aluminum sheets., Regular cleaning of mold surfaces and guide posts/plates is required., The news content you provided does not contain any Chinese text to translate. Please provide the Chinese content for translation., It can also prevent wear on molds caused by aluminum shavings., Precision has decreased., Reducing the lifespan of molds.
3.4 Product Inspection and Repair
In terms of stiffness performance, steel stamping parts exhibit significantly higher stiffness than aluminum stamping parts., Aluminum plate stamping parts are relatively soft. During the component inspection process, to ensure the overall integrity of the aluminum plate stamping parts,, Handle with care. Aluminum stamping parts require a high degree of surface smoothness., The surface inspection methods share certain similarities with the stiffness stamping parts., Visual inspection, tactile inspection, oilstone inspection, and other methods can all be applied to the surface inspection of aluminum stamping parts. However, during the use of tactile inspection and oilstone inspection..., To prevent the inspection method from causing damage to the surface of the stamping parts, The applied pressure requires humidity, Avoid using excessive pressure to prevent part deformation. During the product inspection process, the inspection department can use a polishing jig tailored to the part's profile., Ensuring product inspection quality and efficiency. Due to the low stiffness of aluminum plate stamping parts, Pressings cannot be repaired piece by piece., During the actual production process, it is not guaranteed that all parts will meet the actual requirements., Generally speaking, defects on stamping parts can be retained., And then merge it onto the assembled parts before overhauling.
