Description

Technical Field

[0001] This invention relates to the field of building profile processing technology, and in particular to a sawing and milling machining center and processing method. Background Technology

[0002] The sawing and milling machining center is a CNC composite equipment integrating sawing and milling functions, widely used in door and window, furniture, industrial aluminum, and solid wood processing. Currently, the working principle and overall structural layout of sawing and milling machining centers are relatively mature. They mainly consist of an automatic feeding unit, a milling unit, a sawing unit, and an automatic unloading unit arranged sequentially. The automatic feeding unit adopts a longitudinal feeding and robotic arm clamping structure. The milling unit generally uses a gantry frame with four milling heads. The sawing unit mainly adopts an arbitrary angle sawing structure, while the automatic unloading unit adopts a clamping unloading and longitudinal exporting structure. The longitudinal feeding and exporting are achieved using a synchronous belt conveyor structure. For feeding, a robotic arm continuously clamps the profile from the rear end for feeding. For unloading, a clamping mechanism clamps and transports the cut finished profile. This structure realizes automatic feeding, milling, sawing, and unloading functions, offering advantages such as high automation and high processing efficiency.

[0003] However, existing milling and sawing machining centers also face some new challenges in practical applications. For example, while using a robotic arm to continuously feed the profile from the rear end offers high feeding efficiency, it requires a longer robotic arm and increased stroke to pass the profile through the milling unit to the sawing unit. This necessitates lengthening the frame of the automatic feeding unit by several meters, resulting in a machine length exceeding ten meters. This significantly increases material and transportation costs and places greater demands on space. Similarly, using a synchronous belt conveyor for loading and unloading also offers high efficiency, but it suffers from large footprint and high cost. Therefore, existing milling and sawing machining centers are primarily suitable for large-scale, batch production. For small and medium-sized door and window manufacturers, this presents challenges such as high costs, limited factory space, low utilization rates, and low returns. Therefore, it is necessary to develop a new milling and sawing machining center that retains automation while reducing overall size and cost to meet the needs of small and medium-sized door and window companies. Summary of the Invention

[0021] The beneficial effects of this invention are: (1) By designing the clamping and feeding mechanism, the clamping and discharging mechanism, and optimizing the structure of sawing fixture A and sawing fixture B, the clamping and discharging mechanism can pass through sawing fixture B to reach the position of sawing fixture A to clamp the raw material. Therefore, the clamping and feeding mechanism only needs to transport the raw material to sawing fixture A. Subsequently, the clamping and discharging mechanism can be used to realize the continuous feeding function. Therefore, the clamping and feeding mechanism does not need to clamp from the rear end of the raw material, but can clamp the middle and front part of the raw material. Finally, the length of the feeding unit does not need to be increased, which greatly shortens the overall length of the machine. (2) With the overall size of the sawing processing center greatly shortened, the feeding unit is designed separately, while the sawing unit, milling unit and discharging unit are integrated into a base. This achieves both convenient transportation and greatly shortens the equipment assembly and debugging time. Attached Figure Description

[0023] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0025] like Figure 1-15As shown, the milling and sawing machining center includes a loading unit 1, a milling unit 2, a sawing unit 3, and an unloading unit 4 arranged sequentially. The milling unit 2, sawing unit 3, and unloading unit 4 share a base 5. The loading unit 2 includes a loading frame 6, with a clamping loading mechanism 7 laterally slidable at one end of the loading frame 6 near the milling unit 2. Multiple material support rollers 8 and guide rollers 9 are laterally spaced on the loading frame 6, and multiple longitudinal guiding mechanisms 10 are laterally spaced on the loading frame 6. The milling unit 2 includes a milling frame 11 laterally slidable on the base 5. The milling... The upper end of the frame 11 is longitudinally spaced with milling mechanism A12 and milling mechanism B13; the sawing unit 3 includes a sawing frame 14 integrally formed with the base 5, the upper end of the sawing frame 14 is laterally spaced with sawing angle A15 and sawing fixture B16, and a sawing head 17 is provided between the sawing fixture A15 and sawing angle B16; the discharge unit 4 includes a discharge frame 18 integrally formed with the base 5, the discharge frame 18 is laterally slidably provided with a clamping discharge mechanism 19, and the discharge frame 18 is respectively provided with a lifting material support mechanism 20 and a longitudinal guide mechanism 21. The longitudinal feeding mechanism 10 conveys the raw material to the material support roller 8 and the clamping feeding mechanism 7. The clamping feeding mechanism 7 clamps the raw material longitudinally for feeding, and the distance from the position where the raw material is clamped by the clamping feeding mechanism 7 to the end of the raw material is 1~2m. The clamping feeding mechanism 7 can convey the raw material to the sawing fixture A15. The clamping discharge mechanism 19 can pass through the sawing fixture B16 to reach the position of the sawing fixture A15 to clamp the raw material for continuous feeding. The raw material is milled and sawed during the feeding process. The profile 34 sawn off by the raw material is clamped and conveyed to the lifting material support mechanism 20 through the clamping discharge mechanism 19. The lifting material support mechanism 20 conveys the profile 34 to the longitudinal export mechanism 21. The longitudinal export mechanism 21 exports the profile longitudinally. The remaining part of the raw material after sawing is still clamped and processed by the clamping discharge mechanism 19 through the sawing fixture B16. By designing the clamping and feeding mechanism 7, the clamping and discharging mechanism 19, and optimizing the structure of the sawing fixtures A15 and B16, the clamping and discharging mechanism 19 can pass through the sawing fixture B16 to reach the position of the sawing fixture A15 to clamp the raw material. Therefore, the clamping and feeding mechanism 7 only needs to transport the raw material to the sawing fixture A15. Subsequently, the clamping and discharging mechanism 19 can be used to achieve continuous clamping and feeding. Thus, the clamping and feeding mechanism 7 does not need to clamp from the rear end of the raw material, but can clamp the middle and front part of the raw material. Finally, the length of the feeding unit 2 does not need to be increased, which greatly shortens the overall length of the machine. Compared with the existing sawing and milling machining center, it can be shortened by about 5m. In addition, with the overall size of the sawing machining center greatly shortened, the feeding unit 1 is designed separately, while the sawing unit 2, milling unit 3 and discharging unit 4 are integrated into a base 5. This achieves both convenient transportation and a significant reduction in equipment assembly and debugging time. Existing sawing and milling machining centers are difficult to transport due to their overall length (usually around 17m), requiring them to be disassembled and transported in large quantities, which makes subsequent installation and debugging very troublesome.

[0026] The base 5 is composed of multiple horizontal beams 501 and vertical beams 502 spliced ​​together.

[0027] The clamping and feeding mechanism 7 includes a feeding guide rail 701 horizontally arranged on the feeding frame 6, a feeding slider 702 on the feeding guide rail 701, a feeding slide block 703 on the feeding slider 702, a feeding reducer 704 vertically arranged on the feeding slide block 703, a feeding motor 705 at the input end of the feeding reducer 704, and a feeding gear 706 at the output end. The feeding frame 6 has a feeding rack 707 that meshes with the feeding gear 706. Two material support plates 708 are horizontally spaced on the feeding slide block 703, and two corresponding support plates 709 are horizontally spaced on the feeding slide block 703. A feeding clamping guide rail 710 is longitudinally arranged between the two material support plates 708. The 710 is equipped with a feeding clamping slider 711, the feeding clamping slider 711 is equipped with a feeding clamping slide plate 712, the feeding clamping slide plate 712 is equipped with a feeding clamping plate 713, and the feeding slide block 703 is equipped with a feeding clamping cylinder 714 connected to the feeding clamping slide plate 712; one of the backing plates 709 is equipped with a feeding pressing mounting plate 715 at its upper end, the feeding pressing mounting plate 715 is equipped with a feeding pressing cylinder 716 vertically, the feeding pressing cylinder 716 is equipped with a feeding pressure plate 717 at its lower end, the feeding pressure plate 717 is equipped with a guide shaft A718 vertically, and the corresponding feeding pressing mounting plate 715 is equipped with a linear bearing A719, and the guide shaft A718 is mounted on the linear bearing A719. The specific structure of the clamping and feeding mechanism 7 is given, which realizes the longitudinal clamping of raw materials for feeding. There is a distance between the clamping part of the raw material and the end of the raw material, so the feeding frame 6 does not need to be extended, effectively shortening the length of the feeding frame 6.

[0028] The material support roller 8 and the guide roller 9 are mounted on the mounting support 22, which is mounted on the feeding frame 6. The material support roller 8 is vertically aligned with the material support plate 708, and the guide roller 9 is longitudinally aligned with the guide plate 709.
