Problems solved by technology

[0003] However, based on the characteristics of the CNC machining process itself, there are still problems of large raw material loss and low processing efficiency when processing the second part; at the same time, the tolerance requirements between the first part and the second part are high, otherwise it may The joint precision between the first part and the second part is too low, and it may cause deformation to the first part during the assembly process, reduce the flatness of the overall component after assembly, and even need to readjust the flatness of the overall component or cause the component scrapped

Abstract

The invention discloses a double-metal compound die casting process and component, an electronic device and a machining device. The double-metal compound die casting process comprises the steps that on a first workblank part based on a first metal material is subject to die casting treatment to obtain a first component; multiple second workblank parts based on a second metal material are subject to numerical control machine tool machining to obtain multiple structural parts, and the multiple structural parts can be combined to form a second component matched with the first component; accordingto the combination relation between the first component and the second component, the first component is connected with each structural part. Through the technical scheme, the raw material losses during machining of the second component can be reduced, machining efficiency of the second component can be improved, the requirement for the tolerance between the first component and the second component is low, the combination precision is high, deformation during assembling of the first component and the second component can be avoided, and the flatness after assembling of a whole component is improved.

Description

technical field [0001] The disclosure relates to the technical field of manufacturing technology, in particular to a bimetal composite die-casting technology and components, electronic equipment, and processing equipment. Background technique [0002] The basic principle of the bimetal composite die-casting process is: split the components to be manufactured into two parts, use die-casting to obtain a complete first part, and use a numerical control machine tool (CNC) to process a complete second part, and then the first Parts are bonded with a second part to obtain the desired overall component. Among them, due to the high efficiency, low cost and high yield rate of the die-casting process, the efficient and large-scale production of the first part can be realized, while the CNC processing can meet the refined requirements for the second part, thereby alleviating the related technology. The problem of low efficiency and low yield of full CNC processing technology. [0003...
