Description

Technical Field

[0001] The invention belongs to the technical field of thermal-break aluminum profile processing, and in particular relates to an automatic angle cutting device and method for thermal-break aluminum profiles. Background Art

[0002] Broken bridge aluminum is also called thermal insulation profile. Compared with ordinary profiles, it has better performance. The bridge refers to the hot and cold bridge in the sense of materials science, and the broken means action, which breaks the hot and cold bridge. It can be said that aluminum alloy is a metal material with a fast heat conduction speed. Therefore, when the indoor and outdoor temperatures are high, it can become a bridge for transferring heat.

[0003] Broken bridge aluminum doors and windows have the effect of regulating room temperature, have good air tightness, and can effectively prevent heat loss. However, in the processing of broken bridge aluminum profiles, the cutting of the forty-five-degree angle can only be performed at a single angle. After the cutting at one end is completed, the position of the profile needs to be adjusted to complete the cutting at another angle. The processing process is relatively cumbersome and time-consuming, and the automation intensity is low, which cannot meet the diversified needs for the cutting angles of broken bridge aluminum profiles. For this reason, it is necessary to provide an automatic cutting device and method for broken bridge aluminum profiles, adopt a processing method of variable angle cutting equipment, cut the profile at multiple angles, improve processing efficiency, and adopt automatic stacking to stack the processed profiles, so as to facilitate the user's sorting and transportation. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic corner cutting device and method for thermally broken aluminum profiles, which adopts a processing method of a variable angle cutting device to cut the profiles at multiple angles to improve processing efficiency. At the same time, an automatic stacking method is adopted to stack the processed profiles, thereby facilitating the user's sorting and transportation to solve the above-mentioned technical problems.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: an automated corner cutting method for broken bridge aluminum profiles, which is applied to an automated corner cutting device for broken bridge aluminum profiles, the device comprising a cutting table: a transfer frame is arranged on the right side of the cutting table, a rotating frame is arranged in the inner cavity of the cutting table, a corner cutting assembly is arranged in the inner cavity of the rotating frame, the corner cutting assembly comprises a displacement slide slidably connected to the inner cavity of the rotating frame, a rotating shaft is rotatably connected to the top of the displacement slide, a rotatable saw blade is arranged in the inner cavity of the displacement slide, the saw blade is fixedly connected to the surface of the rotating shaft, a cylinder is fixedly installed on the rear side of the rotating frame, the output end of the cylinder is fixedly connected to the rear side of the displacement slide, an adjustment assembly is arranged in the inner cavity of the cutting table, The adjusting assembly includes a first stepper motor fixedly mounted on the left side of the cutting table, a threaded push rod is rotatably connected to the right side of the inner cavity of the cutting table through a bearing, the left end of the threaded push rod passes through the outside of the cutting table and is fixedly connected to the output shaft of the first stepper motor, a threaded slide is slidably connected to the bottom of the inner cavity of the cutting table, the threaded slide is threadedly connected to the surface of the threaded push rod, the front and rear sides of the bottom of the rotating frame are fixedly connected to swing arms, the front and rear ends of the threaded slide are fixedly connected to push columns, an arc groove matched with the push column is provided on the front side of the swing arm, the top of the transfer frame is fixedly connected to a fixed base, the top of the fixed base is provided with a lifting assembly, and the top of the cutting table is provided with a clamping assembly;

[0006] The method steps for automatic corner cutting of the broken bridge aluminum profile are as follows:

[0007] Step 1: When in use, first move the transfer frame to the right side of the cutting table so that the left side of the transfer frame contacts the right side of the cutting table, then start the conveyor, and convey the broken bridge aluminum profile to the rear side through the conveyor. After being conveyed to the designated position, the electric telescopic rod is opened and pushes the fixed plate, so that the electric telescopic rod and the sliding plate slide in the opposite direction, and then the guide column and the clamping plate move to the rear side, thereby completing the clamping and fixing of the broken bridge aluminum profile, and then start the double-axis motor, which drives the rotating shaft to rotate through the cooperation of the belt pulley and the belt, thereby allowing the saw blade to rotate, and then the cylinder is opened and drives the displacement slide to slide in the inner cavity of the rotating frame, so that the displacement slide, the rotating shaft and the saw blade move, thereby allowing the saw blade to contact the surface of the broken bridge aluminum profile, completing the bevel cutting of the broken bridge aluminum profile, and then the conveyor is opened again and drives the broken bridge aluminum profile and the scraps cut by the broken bridge aluminum profile to move to the right side;

[0008] Step 2: Then, the first stepper motor is turned on and drives the threaded push rod to rotate. During the rotation process, the threaded push rod drives the threaded slide to slide through the thread on its surface. During the sliding process, the threaded slide drives the push column to displace, so that the push column squeezes the inner wall of the arc groove, causing the swing arm to deflect. During the deflection process, the swing arm drives the rotating frame to rotate, so that the rotating frame rotates ninety degrees with the rotating part connected to the cutting table as the rotation center, so that the saw blade is adjusted to tilt forty-five degrees to the left, so that the cutting direction of the saw blade can be adjusted, and then the dual-axis motor and the cylinder are turned on again to cut the left end of the broken bridge aluminum profile, thereby completing the bevel cutting of both ends of the entire broken bridge aluminum profile;

[0009] Step three, the cut thermally-broken aluminum profiles and scraps move to the right under the transmission action of the conveyor, so that the scraps fall into the inner cavity of the material guide box and are discharged, and the cut thermally-broken aluminum profiles reach the top of the stacking platform. According to the stacking height change of the thermally-broken aluminum profiles on the top of the stacking platform, the stacking platform automatically descends to ensure that the thermally-broken aluminum profiles can be stacked on the top of the stacking platform. During the automatic descent, the second stepper motor is turned on and drives the bidirectional threaded rod to rotate. During the rotation, the bidirectional threaded rod drives the two threaded sliders to move in reverse through the action of the surface threads, so that the diagonal support frame is deflected to a certain extent, thereby reducing the support height of the stacking platform. Finally, after the thermally-broken aluminum profiles on the top of the stacking platform are stacked to a certain height, the user moves the transfer frame to transfer the thermally-broken aluminum profiles.

[0034] The method steps for automatic corner cutting of the broken bridge aluminum profile are as follows:

[0035] Step 1: When in use, first move the transfer rack 2 to the right side of the cutting table 1, so that the left side of the transfer rack 2 contacts the right side of the cutting table 1, and then turn on the conveyor 12 to transport the broken bridge aluminum profile to the rear side. After being transported to the designated position, the electric telescopic rod 83 is turned on and pushes the fixed plate 81, so that the electric telescopic rod 83 and the sliding plate 82 slide in the opposite direction, thereby moving the guide column 84 and the clamping plate 85 to the rear side, thereby completing the clamping and fixing of the broken bridge aluminum profile, and then turn on the dual-axis motor 44. The double-axis motor 44 drives the rotating shaft 42 to rotate through the cooperation of the belt pulley 45 and the belt, thereby rotating the saw blade 43.

[0036] Step 2: Next, the first stepper motor 51 is turned on and drives the threaded push rod 52 to rotate.

During the automatic descent, the second stepper motor 72 is turned on and drives the two-way threaded rod 73 to rotate. During the rotation, the two-way threaded rod 73 drives the two threaded sliders 74 to move in reverse through the action of the surface threads thereof, causing the diagonal support frame 75 to deflect to a certain extent, thereby reducing the support height of the stacking platform 71. Finally, after the broken aluminum profiles on the top of the stacking platform 71 are stacked to a certain height, the user moves the transfer frame 2 to transfer the broken aluminum profiles.

Through the setting of the lifting assembly 7, in which the second stepping motor 72 is driven and the two-way threaded rod 73 and the threaded slider 74 are used in coordination, the bottoms of the two diagonal support frames 75 are moved, so that the height of the stacking platform 71 is lowered, and then the stacking platform 71 can be automatically adjusted according to the stacking height of the thermal insulation aluminum profiles, thereby facilitating the user to organize and transport the processed thermal insulation aluminum profiles.

[0039] It is basically the same as the first embodiment, and further: the clamping assembly 8 includes a fixed plate 81 fixedly connected to the rear side of the top of the cutting table 1, and slidable sliding plates 82 are arranged at both ends of the rear side of the fixed plate 81, and guide columns 84 are fixedly connected at both ends of the front side of the sliding plate 82.
