[0026] The angle adjustment mechanism 43 of this embodiment includes a front connecting seat 56 and a rear connecting seat 55. The front connecting seat 56 and the rear connecting seat 55 are respectively fixed on both ends of the feed frame 49. The upper part of the front connecting seat 56 is fixed with a front connecting shaft 58. , The upper part of the rear connecting seat 55 is fixed with a rear connecting shaft 57, the rear connecting shaft 57 is connected to the second reducer 59, and the second reducer 59 is connected to the second servo motor 60; the front connecting shaft 58 and the rear connecting shaft 57 are respectively installed to rotate At both ends of the frame 2, the second reducer 59 and the second servo motor 60 are installed outside the frame 2.
[0027] This embodiment is implemented by a PLC automatic control system. Multiple profiles are placed on the sawing table 3 between the vertical baffle 12 and the positioning frame 13, and the block pressing device 12 and the horizontal pressing device 17 limit the profiles to one layer Closely arranged, the saw blade 44 is located between the left pressing device 13 and the right pressing device 14. The left pressing device 13 and the right pressing device 14 press down to fix the profile, and the feeding mechanism 42 drives the sawing mechanism 41 to realize sawing. Cutting feed, sawing multiple profiles, and adopting the angle adjustment mechanism 43 to realize automatic adjustment of the saw blade according to the requirements of the sawing angle. The specific working process of this embodiment is as follows:
[0028] The profile is sent to the sawing table 3 on the frame 2 through the feeding mechanism, the profile is located between the vertical baffle 22 and the positioning frame 23, and the telescopic shaft of the compression cylinder 15 of the block compression device 12 extends , Drive the compression beam 16 to the set position, the height between the compression beam 16 of the stopper compression device 12 and the plane where the profile is located just allows a layer of profile to pass, the horizontal compression cylinder 19 of the horizontal compression device 17 telescopic shaft Extend through the positioning frame 23, the pressing pad 20 moves forward to compress the profile, and under the limit action of the stopper pressing device 12, the profile between the vertical baffle 22 and the positioning frame 23 is formed into one The layers are tightly arranged. At this time, the compression cylinders 15 of the left compression device 13 and the right compression device 14 are pressed down, and the compression beams 16 of the left compression device 13 and the right compression device 14 fix and compress the profile. The next step is to start During the sawing work, the stopper pressing device 12 only acts as a limit and does not really press on the profile to prevent the horizontal pressing device 17 from pushing the profile, especially the round tube profile, when the profile arches and appears multiple layers Arrangement; when sawing, according to the needs of the sawing angle, the second servo motor 60 rotates, and the second reduction motor 59 drives the rear connecting shaft 57 to rotate, because the rear connecting shaft 57 is fixed on the rear connecting seat 55, and the rear connecting seat 55 Fixed on the feed frame 49, therefore, the rear connecting shaft 57 drives the feed frame 49 to rotate together, while the front connecting shaft 58 also drives the front connecting seat 56 and the feed frame 49 to rotate at the same time, because the sawing mechanism 41 is fixed on the feed frame Therefore, the sawing mechanism 42 rotates at the same time, and the saw blade 44 rotates to a specified angle; during sawing, the third servo motor 54 rotates to drive the nut holder 53 to move on the ball screw 52, and the sawing mechanism 42 is on the wire The female seat 53 moves, and the sliding block 51 moves on the linear guide 50 to guide the sawing mechanism. The saw blade 44 of the sawing mechanism 41 completes the sawing work during the movement. The sawing is accurate and the angle can be adjusted. Tune, high degree of automation.
