Technical Field

[0001] The utility model relates to the technical field of aluminum alloy door and window cutting, in particular to a profile cutting device for aluminum alloy window frames. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles for frames, stiles, and sashes. These include doors and windows with aluminum alloy as the base material for load-bearing rods (rods that bear and transmit deadweight and loads) and doors and windows that are composited with wood or plastic, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. During the processing of aluminum alloy doors and windows, the aluminum alloy profiles need to be cut straight and at angles. The existing cutting method requires workers to measure and draw the lines of the cutting position on the profile before cutting. This is not only labor-intensive, but the cutting process is also prone to problems due to profile offset. Therefore, it is necessary to develop a profile cutting device for aluminum alloy window frames that can reduce the number of profile size measurement steps, reduce the offset caused by repeated installation and cutting, and improve cutting accuracy. Utility Model Content

[0003] In response to the above technical problems, the utility model provides a profile cutting device for aluminum alloy window frames that can reduce the steps of measuring profile dimensions, reduce the deviation of profiles caused by repeated installation and cutting, and improve cutting accuracy, so as to solve the problems of large workload of existing manual line drawing and cutting, and easy deviation of profiles during the cutting process.

The slide is slidably connected to the first slider and the second slider, and the first slider and the second slider are fixedly connected to a four-claw chuck, and the three-way slide groove is slidably connected to the third slider, and the upper end of the third slider is fixedly connected to a support plate, and a telescopic cylinder is arranged behind the support plate, and the output end of the telescopic cylinder passes through the support plate and is fixedly connected to the mounting frame, and a cutting wheel is rotatably connected to the inner side of the mounting frame, and the cutting wheel is driven by a cutting motor, and wing plates with positioning holes are provided on both sides below the first slider, the second slider and the third slider.

[0005] Furthermore, a scale line is provided above the workbench and parallel to the slideway, and the zero scale line of the scale line coincides with the center line of the workbench.

[0006] Furthermore, the chutes on both sides of the three-way chute are at an angle of 45° to the middle chute.

[0007] Furthermore, a guide rail is fixedly connected to the front of the support plate, a guide rod is fixedly connected to the outside of the mounting frame, and the guide rod is slidably connected to the guide rail.

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3The shown device is a profile cutting device for an aluminum alloy window frame, comprising a workbench 1. In order to facilitate fixing the profile according to the profile size, a slide 3 is provided above the workbench 1 along the long side direction. In order to be able to perform angle cutting on the profile without disassembling the fixed profile, a three-way slide groove 4 is provided on one side of the slide 3. A number of limiting holes are provided on both sides of the slide 3 and the three-way slide groove 4. In order to fix the profile, the slide 3 is slidably connected to the first slider 5 and the second slider 6. The first slider 5 and the second slider 6 are fixedly connected with a four-claw chuck 7. The three-way slide groove 4 is slidably connected to the third slider 8. The upper end of the third slider 8 is fixedly connected to a support plate 9. A telescopic cylinder 15 is provided behind the support plate 9. The output end of the telescopic cylinder 15 passes through the support plate 9 and is fixedly connected to the mounting frame 14. A cutting wheel 10 is rotatably connected to the inner side of the mounting frame 14. The cutting wheel 10 is driven by a cutting motor 11. Wing plates with positioning holes are provided on both sides below the first slider 5, the second slider 6 and the third slider 8.

[0017] It should be noted that the four-jaw chuck 7 used in the present invention is an existing structure. In order to adapt to the actual use of the present invention, the four-jaw chuck 7 is changed from the existing circular hole to a square hole.

[0018] In order to facilitate the determination of the profile size, a scale line 2 is provided above the workbench 1 and parallel to the slideway, and the zero scale line of the 2 scale lines coincides with the center line of the workbench 1.

[0019] In order to facilitate the 45° cutting, the two side chutes of the three-way chute 4 and the middle chute are at 45°.

[0020] In order to improve the stability of the device, a guide rail 13 is fixedly connected to the front of the support plate 9, and a guide rod 12 is fixedly connected to the outside of the mounting frame 14. The guide rod 12 is slidably connected to the guide rail 13.

[0021] In order to fix the cutting motor 11 and avoid position conflicts between the cutting motor 11 and the guide rod 12 and the guide rail 13, the two sides of the cutting wheel 10 are rotatably connected to the mounting frame 14 through a rotating shaft, the cutting motor 11 is fixedly connected to the outside of the mounting frame 14, the output shaft of the cutting motor 11 is fixedly connected to the rotating shaft at one end, and the guide rod 12 is arranged below the support frame 14.

[0022] The working process of this embodiment is as follows:

[0023] When cutting aluminum alloy profiles, the profile is clamped into the four-jaw chuck 7 on the first slider 5 and locked, and then the positions of the first slider 5 and the second slider 6 are adjusted. Then, the other end of the profile is clamped into the four-jaw chuck 7 on the second slider 6 and locked. Then, bolts are passed through the positioning holes on the wing plate and the workbench 1 to lock it, and the third slider 8 is pushed into the three-way slide 4. According to the needs of straight cutting and angle cutting, the third slider 8 is moved to the required position, and the limiting holes of the wing plate and the workbench 1 are locked by bolts. The cutting wheel 10 is controlled to move forward by the telescopic cylinder 15, and the cutting wheel 10 is controlled to rotate by the cutting motor to complete the straight cutting and angle cutting of the aluminum alloy profile.
