Description

Technical Field

[0001] The present invention relates to the technical field of profile cutting, and in particular to a cutting device for door and window processing. Background Art

[0002] Frequently used door and window profiles include aluminum alloy profiles, wooden profiles, plastic profiles, steel profiles, and glass profiles, etc. There are two most commonly used door and window profiles in most families. One is made of aluminum alloy, and the other is made of plastic steel. The popularity of these two materials in the market is particularly high, so the processing and cutting of door and window profiles will also be particularly particular.

[0003] However, when cutting plastic steel profiles, the blade is prone to overheating during long-term operation. When the cut surface of the plastic steel profile comes into contact with the overheated saw blade, it is easy to cause the melting of the end face of the plastic steel profile. The residues generated by melting are easily adhered to the saw blade, which not only affects the rotational balance of the saw blade, but also affects the cutting effect of the saw blade, and is more likely to cause the unevenness of the cutting end face of the plastic steel profile. For this reason, a cutting device for door and window processing is proposed. Summary of the Invention

On the side of the round pipe 652 close to the saw blade one 57, there are opened a plurality of spraying holes 653 distributed linearly.

[0024] On the vertical seat 51, there is fixedly installed a vertically arranged linear module one 52. On the slider of the linear module one 52, there is fixedly installed a horizontally arranged linear module three 512. On the slider of the linear module three 512, there is fixedly installed a mounting seat one 53. The mounting seat two 55 is rotatably installed at the bottom of the mounting seat one 53. On the mounting seat one 53, there is fixedly installed a rotating table 54 for driving the mounting seat two 55 to rotate.

[0025] On the vertical seat 51, there is fixedly installed a vertically arranged linear module two 58. On the slider of the linear module two 58, there is fixedly installed a mounting seat three 59. On the top of the mounting seat three 59, there is fixedly installed a motor two 510. The saw blade two 511 is fixedly connected to the output shaft of the motor two 510.

[0026] In this embodiment: The profile to be cut is clamped and fixed by the clamping device 1 2, the clamping device 2 3, and the clamping device 3 4, and the profile is positioned between the saw blade 1 57 and the saw blade 2 511. When a 45-degree cut of the profile is required, only need to make the linear module 2 58 drive the motor 2 510 to move upward, and drive the saw blade 2 511 to rotate through the motor 2 510 to cut the profile, or adjust the angle of the motor 1 56 through the rotary table 54, and then make the linear module 1 52 drive the motor 1 56 to move downward, and drive the saw blade 1 57 to rotate through the motor 1 56 to cut the profile; When a cut of the profile at an angle other than 45 degrees is required, the saw blade 1 57 needs to be used. In this case, first drive the mounting seat 2 55 to rotate through the rotary table 54, and the mounting seat 2 55 then drives the saw blade 1 57 to rotate through the motor 1 56, so that it can present different angles. Then drive the saw blade 1 57 to move downward through the linear module 1 52 to cut the profile at other angles; As Figure 4 、 Figure 9 shown, when the saw blade 1 57 rotates clockwise to cut the plastic-steel profile, by connecting two hoses 654 to the external coolant, after the coolant enters the round tube 652, it is atomized and sprayed out through multiple spray holes 653 and lands on the saw blade 1 57. After the coolant is sprayed on the saw blade 1 57, it can not only cool the saw blade 1 57, but also cool and solidify the plastic-steel slag that is melted and adhered due to high temperature; As Figures 4 - 9 shown, when the motor 1 56 drives the saw blade 1 57 to rotate through the fixed shaft 561, the fixed shaft 561 will drive two collar rings 671 to rotate synchronously, and the collar rings 671 drive the guide wheels 673 to rotate through the columns 672. When the guide wheels 673 abut against the slope surface 6651, as the collar rings 671 continue to rotate, the guide wheels 673 will push the wedge blocks 665, the rectangular spring telescopic rods 6610, the swing arms 663, and the scraping plates 661 to rotate clockwise around the fixed shaft 561. During this process, the sliding sleeve 669 will compress the return spring 668; When the two swing arms 663 rotate clockwise, they will drive the two rotating rings 682 and the inclined scraping bars 683 to rotate synchronously with the saw blade 1 57. When the two swing arms 663 rotate clockwise for half a week, since the two connecting rods 1 662 and the two connecting rods 2 684 abut against the inner walls of the corresponding semi-circular holes 1 611 and the semi-circular holes 2 63 on the other side respectively, they will not be able to rotate. At this time, the continuously rotating fixed shaft 561 will push the two wedge blocks 665 through the two guide wheels 673 and compress the corresponding rectangular spring telescopic rods 6610. When the two columns 672 are separated from the corresponding wedge blocks 665, the two compressed return springs 668 will reset; During the process of the two reset springs 668 driving the two swing arms 663 to reset after being compressed, at this time, the first saw blade 57 will continue to rotate clockwise, while the two inclined scraping bars 683 will rotate in opposite directions. At this time, the two inclined scraping bars 683 will sweep across the surface of the first saw blade 57. The first saw blade 57 can scrape off the plastic-steel slag that has cooled and solidified on the first saw blade 57, and during the rotation of the inclined scraping bars 683, the scraped slag can be thrown away by centrifugal force, enabling it to enter the chip storage cavity 614 through the gap between the two flexible retaining bars 613; The slag that enters the chip storage cavity 614 will be pushed to one end of the chip storage cavity 614 by the scraping plate 661 that sweeps across the chip storage cavity 614, causing it to fall into the corresponding chip discharge pipe 64 and be automatically discharged. In summary, during the process of the fixed shaft 561 driving the first saw blade 57 to rotate, the two cleaning mechanisms 68 and the scraping plate 661 will perform a reciprocating half-turn rotation. During this process, the scraping plate 661 can push the slag that has fallen into the chip storage cavity 614 into the two chip discharge pipes 64 for self-discharge, while the two cleaning mechanisms 68 scrape off the slag attached to the first saw blade 57 after cooling through the corresponding inclined scraping bars 683 and throw it into the chip storage cavity 614.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
