- Mar 19, 2018-

With the development of electronic industry, Aluminum Alloy thin-wall parts has been widely used in this kind of parts has the advantages of light weight, compact structure, but this kind of parts has been difficult to long processing cycle and high processing cost, the precision is difficult to control, the reason is the removal of metal parts during the process, a large amount of low rigidity the strength, weak, prone to large deformation, after processing is difficult to ensure the machining precision and surface quality. In this paper, from the analysis of the causes of the deformation of the parts, the process methods of controlling and reducing the deformation of the aluminum alloy thin-walled cavity parts are studied and discussed.

Aluminum pipe can process parts with strong corrosion resistance. The processing technology includes casting process. But when implementing this technology, it will cause the deformation of products easily, and how to reduce the occurrence of such a situation.

1, we suggest that you use the axial clamping fixture, which is also a simple method to prevent the deformation of aluminum rods.

2, add the cutting fluid to cool the workpiece, so that the casting deformation of the aluminum rod can be reduced.

3, the clamping contact surface, such as the use of the slit sleeve, makes the contact surface increase, and the clamping force is evenly distributed on the workpiece, and it is not easy to produce deformation. This method can also improve the clamping precision of the three - claw self - fixed core chuck, and can reach a high coaxiality.

4, increase the process rib in the clamping part of the copper sleeve, specially made of several technological ribs, the clamping force on the rib, in order to reduce the deformation of the aluminum rod.

Aluminum tube has brought many conveniences to our industrial production and life. Reducing its casting deformation can effectively reduce the loss and increase the efficiency of the enterprise.

The main factors affecting the machining accuracy and surface quality of the aluminum alloy thin-walled cavity parts are the easy deformation during the processing of this kind of parts. To solve the deformation problem of aluminum alloy thin-walled cavity parts during machining, we can improve the working efficiency of milling parts, improve the accuracy and quality of parts, and achieve rapid product production.

The machining process of aluminum alloy thin-walled cavity parts is analyzed. The parts are generally processed by aluminum alloy plate. The metal removal is large and the rigidity is low. During the processing, three factors such as residual stress, clamping force and cutting motion will cause deformation.

During the machining process of aluminum alloy thin-walled cavity parts, from the following four aspects: optimization of process flow, heat treatment, improvement of clamping methods and high-speed machining, combined with the structural characteristics of parts, a reasonable process and processing plan are worked out. The machining deformation of parts can be solved, and the machining accuracy and surface quality of the parts are improved.
