Description

technical field [0001] The invention belongs to a wood forming processing device, in particular to a pyrolysis wood surface forming processing device. Background technique [0002] The processing of wood has experienced manual, mechanized, and digital development, but this process has always relied on metal tools to directly perform sawing, planing, filing, milling, turning, carving and other processing methods on wood. Our country's traditional wooden carving products have a unique style with exquisite carving art and shape, which is the perfect combination of technology and art. Art cultivation, which has long relied on manual skills for inheritance, has also become a bottleneck restricting the in-depth development of this skill and the realization of large-scale, batch, low-cost, and high-efficiency production. With the widespread application of CNC (computer numerical control) technology in the machining industry, the use of multi-axis CNC equipment to process complex 3...

Problems solved by technology

However, there is a big difference between the CNC processing of wood and metal. In addition to the significant differences in the physical and chemical properties of wood and metal, metal processing is usually standardized processing, while wood processing pays more attention to aesthetics and artistry. The product surface is often a complex and uncertain 3D random field, it is difficult to find a unified and standardized processing method, so it is more complex and uncontrollable

[0003] At present, the research and practice of digital woodworking engraving technology shows that there are still some insurmountable defects when engraving complex 3D surface models such as classical carved furniture with numerical control equipment. It is also often easy to cause workpiece chipping, edge cracking, etc., and it is difficult to realize the processing of complex curved surfaces

At the same time, since the CNC system needs to adopt a close-loop layered processing method for the processing of complex 3D curved surfaces, the number of steps, travel and time required for the tool to start from a certain point to complete the processing of each layer of the circuit and the entire curved surface are huge. If If the processing thickness and loop spacing of each layer are set small, it will still be a time-consuming and low-efficiency processing process, but if these parameters are set large, there will be tool breakage, skipping, cracking or blocking at any time during the processing Death and other possibilities, and it is difficult to obtain the ideal processing effect, and more post-processing procedures are required

[0004] The laser removal molding technology of wood that has appeared in recent years is a new technology different from the traditional processing method of wood surface. It uses numerical control equipment to drive the laser generator, and uses the high-temperature sintered wood surface generated by the laser to form patterns. At present, the processing technology can only process very shallow patterns on the surface of wood, and cannot obtain the complex 3D surface effect of products such as Chinese classical carved furniture, and the equipment is expensive, consumes a lot, and the processing cost is high

[0005] In addition, the so-called soldering iron painting that appears is to use electric heat to form painting patterns on the surface of the wooden board. This requires highly skilled professionals to completely rely on manual operation of the electric soldering iron to complete. It can only create a very shallow surface pattern effect, and the efficiency is low and it is not suitable for industrialization. Production
