Description

Technical Field

[0001] The present invention belongs to the field of composite processing technology, and specifically relates to a portable additive and subtractive composite manufacturing device that can perform ultrasonic vibration, cold and hot treatment assisted incremental forming, additive manufacturing, in-situ rolling, and milling reduction. Background Art

[0002] As a new type of flexible, mold-free processing technology for sheet metal, incremental forming has the characteristics of low forming force, good manufacturing flexibility, high material utilization rate, and strong forming capability. At the same time, it can greatly shorten the production cycle and processing cost in small batch and customized forming modes, but it is difficult to form block features and complex structures.

[0003] Additive manufacturing is a manufacturing technology that achieves complex shapes by stacking materials layer by layer. Additive manufacturing technology has the characteristics of high material utilization, short production cycle, and complex formed parts. However, the dimensional accuracy and surface quality of additively manufactured components are difficult to meet design requirements. After additive manufacturing, it is necessary to clamp the workpiece again and perform milling and other finishing methods to solve problems such as insufficient precision and poor quality.

[0004] Milling is a traditional manufacturing process that forms parts by removing material. The milling process has the characteristics of high processing precision, high forming efficiency, wide application range, and strong controllability. Among them, the five-axis machining process can achieve precise forming of complex features, but there are problems such as material waste, high tool cost, high equipment cost, and long processing time. Additive and subtractive composite manufacturing can achieve the effect of combining additive near-net forming and subtractive precision.

[0005] Patent authorization announcement number CN 115488635 B discloses an additive composite manufacturing tool that can be modified by ultra-low temperature and heat treatment. It uses cold and heat treatment assisted incremental forming-laser additive composite manufacturing to achieve composite manufacturing of complex thin-walled metal components with block characteristics under cold and heat treatment synergistic modification. However, it does not consider the finishing optimization of surface quality after additive manufacturing. At the same time, the composite manufacturing tool needs to be connected to a robotic arm to work, which has high manufacturing costs and is not convenient for disassembly and movement. Patent authorization announcement number CN 114101712 B discloses an integrated arc 3D printing additive and subtractive manufacturing system and additive and subtractive processing method. Through the cooperation of an arc additive printing system, a milling subtractive processing system, and a millimeter energy processing system, it can achieve simultaneous printing, finishing, and rough processing. However, the gantry system is large in size, the processing equipment is expensive, and it is difficult to move. At the same time, it lacks the synergistic auxiliary modification of an external energy field. Patent publication number CN 117380977 A discloses an incremental forming-laser additive manufacturing composite processing tool head and processing system. The device is simple, portable and low-cost through a folding connection. It can realize the alternating extrusion forming and laser additive manufacturing of thin-walled components, which is convenient for the processing and forming of complex-shaped parts with thin-wall features. However, the top of the incremental forming processing tool is drilled to destroy the rigidity of the tool through high-energy laser. The high-energy laser passes through the coaxial laser channel of the tool head, causing the tool head to heat up, affecting the service life of the tool, and it is impossible to achieve coordinated printing of multiple materials such as wire and powder.

[0084] 1. After the bowl-shaped base and the block platform are formed, the block platform is prepared for milling to further improve the surface quality and shape accuracy of the workpiece.

[0085] 2. According to the specific structure of the bowl-shaped base and the block-shaped platform, clamp the appropriate CNC milling cutter and fixture to avoid overcutting and interference.
