Problems solved by technology

[0005] However, for components with an internal closed cavity structure, such as cooling plates, in addition to the split processing method, traditional friction stir welding still lacks effective processing methods. Therefore, can the whole material be used, by welding Technology and cutting technology are integrated, and it is of great significance to carry out joint processing and manufacturing to form parts with an internal closed cavity structure at one time. For traditional mechanical manufacturing methods, this processing technology is also an important tool for

Example

[0075] Example 1: Manufacturing and processing of marine aluminum alloy serpentine channel ice-making plates. 2214 aluminum alloy material, the size of which is 1.6m in length, 1m in width, and 10mm in thickness, is processed by cutting-friction stir welding combined processing equipment and its method. The speed is 1600r / min, the welding speed is 80mm / min, argon is used as the shielding gas, and the flow rate is 180L / min, water-based environmentally friendly milling fluid is used for milling, and the lead-out plate is used for cutting-friction stir welding composite processing The tool makes no keyholes on the aluminum alloy plate, and uses high-pressure gas to clean the hollow serpentine flow channel to complete the overall near-net molding of the hollow serpentine flow channel of the ice-making plate.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing parts processing, in particular to a cutting-friction stir welding combined processing equipment and a manufacturing method thereof. Background technique [0002] At present, for the manufacture of structural parts with internal closed cavities, the traditional manufacturing methods mainly include the use of profile welding, plate welding and bulging processing, or the entire workpiece is cut and then sealed with a cover plate. These traditional processing methods have many steps, long manufacturing cycle, high manufacturing cost, and the workpiece is easily deformed, which affects the strength of the structural part. [0003] In 1991, W.M.Thomas of the British Welding Institute (TWI) invented the friction stir welding technology. This new welding technology derived from the mechanical cold processing manufacturing process and based on the solid phase connection has obvious advant...
