Description

Technical field:

[0001] The utility model relates to the technical field of intelligent processing of profiles, in particular to a hoisting type front and rear split milling device and a sawing and milling workstation. Background technology:

[0002] Milling is an essential process in the production of doors and windows, curtain walls, sunrooms, etc. It mainly processes holes and grooves, such as lock mounting holes and drainage grooves (holes). At present, there are two main types of equipment for milling in the door and window industry. One type is equipment that performs milling independently, such as CNC drilling and milling machines and CNC drilling and milling processing centers. CNC drilling and milling machines have the advantages of mature technology, small size, and low cost. For specific structures, please refer to a multi-angle CNC drilling and milling machine disclosed in a Chinese patent (authorization announcement number: CN219704142U). Its main working principle is that the drilling and milling head can perform three translations in space, and the profile can be flipped under the clamp for processing different surfaces. The working principle of the CNC drilling and milling processing center is similar to that of the CNC drilling and milling machine. The main difference is that it is larger in size and equipped with a tool magazine, which can automatically change tools according to needs. The other type needs to be integrated with other processes. For example, the currently popular sawing and milling workstation (also called sawing and milling processing center) integrates milling and sawing processes to achieve automatic loading, milling, sawing, and automatic unloading. Some will also perform labeling during the unloading process. At present, there are relatively mature sawing and milling workstations on the market, such as a CNC sawing and milling machine for six-sided processing of door and window profiles disclosed in a Chinese patent (application number: 202311718742.3), and a multifunctional profile automatic sawing and milling processing system and method disclosed in a Chinese patent (application number: 202311437539.9). Through research on existing sawing and milling workstations and combining user feedback, it was found that although the existing sawing and milling workstations have a high degree of overall automation, the actual production efficiency has not met expectations. The main reason is that there is a time difference in the coordination of the two processes. Sawing efficiency is higher, while milling usually takes a longer time. This results in sawing having to wait for milling to be completed, thus limiting the overall processing efficiency. In addition to the large number of milling processing points, another important reason for the above problems is that the existing milling structure generally adopts an integrated design, that is, all milling heads are integrated together to share one or two translations. This makes it impossible for multiple milling heads to work at the same time. Only one milling head can be used at a time, which undoubtedly restricts the milling efficiency. This integrated design seems to save costs, but it seriously restricts the milling efficiency. At the same time, it is inconvenient to install, overhaul and maintain, and the comprehensive cost of use is not low. Therefore, it is necessary to re-layout the existing milling structure in order to significantly improve the milling efficiency, match it with the sawing efficiency, and make the overall efficiency of the sawing and milling workstation higher.
