Composite squeeze casting is a complex forming method suitable for large parts. Because of its difficult process, high functional requirements
Forming method of composite squeeze casting for large castings, design and manufacture composite squeeze casting forming equipment and peripheral devices,
At present, the theoretical analysis method of squeeze casting is not very perfect. There is no ideal design method of
1. Defect characteristics Pores are found around the hot joint of the cut workpiece, and pores are also found on
1. Defect characteristics Through the observation of the surface of the extruded bucket tooth casting, it is found that a
There are two main forms of incomplete forming of bucket teeth in Squeeze Casting: incomplete bucket teeth and incomplete forming
Squeeze casting technology continuously applies pressure to the liquid metal in the forming process, which makes the liquid metal solidify
The 110 engine support of a commercial vehicle is shown in Figure 1. It has a long life cycle and
Figure 1 shows the aluminum alloy control arm. The material is A356.2 alloy, and the maximum overall dimension is 320mm
The airbag support arm is the core support part of the vehicle wheel drive axle, as shown in Figure 1.
The steering knuckle is a chassis safety part, which has the functions of connection, bearing and steering, and the service
Squeeze casting can make the liquid metal form, solidify or accompanied by a small amount of plastic deformation under high
The segregation behavior of impurity elements needs to be analyzed from the aspects of solidification thermodynamics and kinetics. From the
According to the data in Table 1, the segregation position of each element along the longitudinal direction can be further
On the whole, the impurity segregation of reverse squeeze casting belongs to positive segregation. The last position of reverse filling
The contents of impurity elements at different positions in A356 aluminum alloy wheel hub by reverse squeeze casting are shown
The results show that the segregation zone with high impurity element content is located at position 1 and the segregation
The test material is A356 aluminum alloy, and its chemical composition is controlled according to American Standard b108-03a. A heavy
Due to the effect of flow and high pressure in squeeze casting, it is difficult to avoid the component segregation
In the process of solid solution, the alloy elements are dissolved into the base metal, the hardness and strength of
In this paper, the rheo squeeze casting technology of 7075 aluminum alloy was studied, and the process parameters of rheo
After determining 475 ℃ as the best solution temperature, four 15 × 15 × 15mm heat-treated samples were taken from
Hardness test is the most simple and easy method in mechanical property test. In order to replace some mechanical property
The equipment of rheo squeeze casting is few, and the general experiment is to use the general four column hydraulic
The effect of injection specific pressure on the mechanical properties of 7075 alloy by rheo squeeze casting is shown in
According to the classification of squeeze casting process, indirect squeeze casting was used in the experiment, and the “translational pouring
The volume of 7075 aluminum alloy shrinks when it crystallizes. For squeeze casting, solidification under pressure will increase the undercooling
Through lspsf process, connecting with the special semi-solid vertical squeeze casting equipment developed by the laboratory, and adopting reasonable process
The squeeze casting molding machine is equipped with manual and linkage working modes. A kind of working procedure is preset
