Description

Technical Field

[0001] The invention relates to the technical field of machine tool metal cutting and processing, in particular to a cutting device for producing metal door and window frames. Background Art

[0002] Doors and windows are divided into enclosure components or partition components according to their location. They have different design requirements and must have one or more functions such as heat preservation, thermal insulation or sound insulation. Some doors and windows are now made of aluminum alloy profiles. The lightness of aluminum alloy profiles is deeply loved by everyone. The surface of aluminum alloy is oxidized and shiny. The window frame is large and can be inlaid with a large area of ​​glass, allowing sufficient and bright indoor light, enhancing the virtual and real contrast between the indoor and outdoor facades, and making the room more layered. Aluminum alloy itself is easy to extrude, the cross-sectional dimensions of the profile are precise, and the processing accuracy is high. Therefore, many owners choose to use aluminum alloy doors and windows in decoration.

[0003] However, since the aluminum profiles of aluminum alloy doors and windows are of different sizes, multiple groups of aluminum profiles need to be positioned and moved before cutting, which can easily cause the aluminum profiles to shift, resulting in the need for secondary calibration before each cutting, and low cutting efficiency. In addition, since most aluminum profiles for doors and windows are special-shaped parts, the conventional simple clamping structure cannot meet existing production needs. Excessive pressure can easily damage the protrusions of the special-shaped surface, and low pressure can easily cause shaking during cutting, so structural improvements are needed.

[0058] Working principle:

[0059] When in use, multiple groups of aluminum profile tubes in the array are conveyed into the first pushing assembly 2 through the linear conveyor 1. The spacing and height of the photoelectric distance sensor 341 are adjusted according to the plane and groove position of the side of the aluminum profile, so that the photoelectric distance sensor 341 is aligned with the plane of the side of the aluminum profile. Then, the spacing and position of the first pressing piece module 45 and the connecting frame 75 are adjusted according to the size of the aluminum profile. The lower end surface of the aluminum profile contacts the electric roller 211. The third cylinder 31 pushes the first pushing column 331 to approach and contact the aluminum profile. When the pushing frame 32 moves forward, the following frame 33 rotates and unfolds, pushing the aluminum profile to move sideways and contact the guide wheel 242. After the gap between the aluminum profiles disappears, the pressure sensor 35 detects the pressure of the following frame 33 retreating, and stops moving forward after reaching the specified pressure.

[0060] The first push assembly 2 drives the first pressing member assembly 4 to descend, and the pressing wheel 4541 and the second push column 456 contact the upper end surface of the aluminum profile. Figure 11-14 As shown, the spacing between the pressing wheels 4541 is adjusted and the second pushing column 456 is installed and removed according to the shapes of different aluminum profiles, so as to meet the pressing requirements of aluminum profiles of different sizes and styles. Then, the electric roller 211 is started to push the aluminum profile forward to enter the top of the first bracket 51, and the forward distance of the aluminum profile is controlled according to the required cutting length. The angle of the first bracket 51 is adjusted according to the required cutting angle. After the cutting length and angle are determined, the activity stops;

[0061] Then the second push assembly 6 pushes the second pressing piece assembly 7 down, and the pressing block 76 contacts the upper end surface of the aluminum profile and presses it. When the upper end surface of the aluminum profile is a horizontal plane, such as Fig.13 , 14 As shown, the long side of the pressing block 76 is horizontal with the lower bracket 71, and the lowering of the connecting frame 75 can better perform the pressing operation on the upper end surface of the aluminum profile. When the upper end surface of the aluminum profile is a special-shaped surface, such as Fig.11 , 12As shown, the third electric cylinder 72 pushes the second sliding frame 73 forward, and the rack 74 pushes the pressing block 76 to rotate 90 degrees. At this time, the short side of the pressing block 76 is horizontal with the lower bracket 71, which can effectively avoid the protrusion of the special-shaped surface on the aluminum profile, and at the same time, the aluminum profile can be pressed without shaking and misalignment. The cutting machine 53 starts to move and cut, and the circular blade 531 enters the first slot 761 or the second slot 762;

[0062] After the cutting is completed, the cutting machine 53 descends, takes away the cut piece, and then repeats the above operation to perform subsequent cutting work.
