[0025] The crawler vehicle 2, the first servo motor 5, the electric telescopic rod 9, the electric lifting rod 11, the spindle motor 13, the electric drive rod 15, the laser rangefinder 23, the second servo motor 36, the third servo motor 37 and the conveying motor 50 in this embodiment are all conventional equipment purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and they will not be described in detail here.

[0026] In summary, the working principle of the metal cutting device for door and window manufacturing is that before use, the metal cutting device for door and window manufacturing is firstly formed into a matching electrical device and debugged, and a controller and a control handheld are installed for the crawler 2, the first servo motor 5, the electric telescopic rod 9, the electric lifting rod 11, the spindle motor 13, the electric drive rod 15, the laser rangefinder 23, the second servo motor 36, the third servo motor 37 and the conveying motor 50. The control handheld can send operation commands to the controller and feedback on the execution of the controller commands. The laser rangefinder 23 can transmit the detected data to the controller to form the measurement and determination of the cutting length of the metal profile, and the calculation program of the cutting length of the metal profile is written in the controller, as shown in the attached figure. Fig.18 As shown, L is the distance from the laser rangefinder 23 to the end of the metal profile measured by the laser rangefinder 23, and b is the distance from the laser rangefinder 23 to the bottom of the metal profile. Since the distance b is perpendicular to the bottom of the metal profile, the Pythagorean theorem can be used to deduce , which can form an attached Fig.18 The calculation of the distance at a in Fig.18 The distance d in the figure is the straight-line length from the saw blade 1 to the laser rangefinder 23. The data of distance d plus the data of distance a are the length of the metal profile after the saw blade 1 cuts it. According to the elongation degree of the electric drive rod 15, the dimension data of b and d of the rotating ramp frame 14 and the linkage ramp frame 38 in different postures in the crawler vehicle 2 are pre-measured, and the pre-measured dimensions are stored in the central controller for subsequent use.

[0027] Furthermore, when it is necessary to cut the metal profile, the front end of the rotating ramp frame 14 is first adjusted relative to the metal profile through the travel function of the crawler vehicle 2. As the crawler vehicle 2 approaches the metal profile, the electric drive rod 15 operates to realize the rotation adjustment of the rotating ramp frame 14 relative to the crawler vehicle 2, so that the front end of the rotating ramp frame 14 rotates and falls until the front end of the rotating ramp frame 14 contacts the ground. During the rotation and falling process of the rotating ramp frame 14, under the sequential transmission action of the driving outrigger 43, the transmission plate frame 45 and the driven outrigger 44, the linkage ramp frame 38 will rotate and rise in the crawler vehicle 2. The rotating and raised linkage ramp frame 38 will increase the gap distance between it and the rotating ramp frame 14, so as to facilitate the metal profile on the rotating ramp frame The relative passage between 14 and the linkage ramp frame 38 maintains the aforementioned adjustment state through the crawler vehicle 2 continuing to form a relative approach with respect to the metal profile until the end of the metal profile close to the rotating ramp frame 14 is scooped up by the rotating ramp frame 14. Thereafter, the crawler vehicle 2 continues to move to achieve a relative sliding displacement of the metal profile with respect to the rotating ramp frame 14, and in the scooping process, when the metal profile cannot adapt to the scooping action and forms a synchronous movement under the pushing action of the rotating ramp frame 14, an appropriate limit is formed relative to the end of the metal profile away from the rotating ramp frame 14 through external equipment or structure, so as to ensure that the rotating ramp frame 14 can scoop up the metal profile smoothly. In this process, the inclination degree of the rotating ramp frame 14 is appropriately adjusted according to the specific inclination of the metal profile, so that the rotating ramp frame The top end of 14 is close to a relatively parallel state with the bottom end of the metal profile, which also facilitates the contact support of multiple bottom conveying rollers 19 relative to the metal profile, so as to reduce the scraping loss caused by one end of the metal profile entering the rotating ramp frame 14 to the rotating ramp frame 14. In the process of the rotating ramp frame 14 rotating and rising relative to the crawler vehicle 2, the linkage ramp frame 38 will also rotate and fall relative to the crawler vehicle 2, so that the relative distance between the linkage ramp frame 38 and the rotating ramp frame 14 is reduced, thereby achieving the metal profile entering between the linkage ramp frame 38 and the rotating ramp frame 14. In the process of the linkage ramp frame 38 forming a compression limit relative to the metal profile, the conveying pressure roller 42 will first form a relative contact and compression with the metal profile. At this time, if the rotating ramp frame 14 does not rotate further, When the metal profile is raised, under the action of the connecting spring 49, the linkage ramp 38 will maintain a certain distance relative to the metal profile. In this state, the first pair of shift blocks 39 and the second pair of shift blocks 40 will be staggered in the upper and lower heights relative to the metal profile, that is, the first pair of shift blocks 39 and the second pair of shift blocks 40 will further align the metal profile in the center. The operation of the conveying motor 50 will form a movement drive of the synchronous soft belt 53 through the driving pulley 52. ​​The movement of the synchronous soft belt 53 drives the multiple synchronous pulleys 51 to rotate. The rotation of the multiple synchronous pulleys 51 will drive the multiple conveying rollers 42 to rotate to realize the auxiliary conveying movement of the metal profile between the rotating ramp 14 and the linkage ramp 38, forming a corresponding adjustment of the cutting point on the metal profile. The laser rangefinder 23 detects the passing distance of the metal profile.

[0028] Furthermore, during the detection process, the operation of the second servo motor 36 can realize the left-right adjustment of the laser rangefinder 23, so that the laser rangefinder 23 can form a corresponding left-right detection with the end of the metal profile in width. The third servo motor 37 works to form a rotation adjustment of the mounting turret 31 through the meshing transmission of two gears, so that the up-and-down rotation adjustment of the moving seat 34 can be formed through the transverse axis 33, so that the laser rangefinder 23 and the end of the metal profile form an adaptive adjustment. During the detection process, when the laser rangefinder 23 has detection data within a certain range, it means that the light emitted by the laser rangefinder 23 is irradiated on the metal profile. With the increase of the angle between the light emitted by the laser rangefinder 23 and the metal profile, when the detection data of the laser rangefinder 23 After the detection data increases significantly or disappears instantly, the detection data increases significantly instantly, which means that the metal profile no longer forms a corresponding detection for the light emitted by the laser rangefinder 23. The light emitted by the laser rangefinder 23 is irradiated on objects other than the metal profile. The absence of detection data instantly means that the metal profile no longer forms a corresponding detection for the light emitted by the laser rangefinder 23. The light emitted by the laser rangefinder 23 cannot irradiate the response surface, so the detection data cannot be formed. The detection data of the critical point before the detection data increases instantly or disappears instantly is the effective detection value of the L data value. The corresponding values ​​of d and b are retrieved according to the inclination angle of the rotating ramp 14. The value of a is formed by combining the value of L and the value of b according to the Pythagorean theorem. Calculation is performed, and finally the size of the saw blade 1 and the metal profile passing through one end of the crawler vehicle 2 is judged by adding the value a and the value d. When the cutting position of the metal profile meets the cutting requirement of the metal profile, the conveying motor 50 stops to form a plurality of rotation limits of the conveying rollers 42, and then the spindle motor 13 is powered on. The output end of the spindle motor 13 and the mounting spindle 12 are both equipped with a transmission pulley, and the two transmission pulleys are connected by a transmission belt transmission. Therefore, the spindle motor 13 is powered on to realize the rotation drive of the mounting spindle 12, and the rotation of the mounting spindle 12 drives the saw blade 1 to rotate. After the saw blade 1 rotates stably, the electric lifting rod 11 is powered on to realize the relative height reduction of the lifting frame 10 relative to the rotating frame 6, so that the saw blade 1 is relative to the metal The profile forms a cutting feed motion, and when the metal profile is wider, the saw blade 1 can be swung left and right by powering on the electric telescopic rod 9 to increase the lateral cutting range of the saw blade 1. At the same time, when the metal profile needs to be beveled, the first servo motor 5 is powered on, and the meshing transmission of the spur gear on the output shaft of the first servo motor 5 and the spur gear ring outside the turntable frame 4 can form an adjustment of the turntable frame 4 relative to the linkage ramp frame 38, so that the saw blade 1 forms a bevel adjustment relative to the metal profile. When the cutting accuracy of the metal profile is required to be high or the material hardness is high, on the basis of the above, the electric drive rod 15 is operated to further control the rotation and elevation of the rotating ramp frame 14, so that the relative distance between the rotating ramp frame 14 and the linkage ramp frame 38 is further reduced.During this process, the connecting spring 49 is continuously elastically stretched until the bottom surface of the linkage ramp 38 forms a mutual contact and compression effect with respect to the metal profile, so as to improve the compression and positioning effect of the metal profile and reduce the occurrence of relative displacement of the metal profile between the rotating ramp 14 and the linkage ramp 38 caused by vibration during the cutting process.
