[0002] Aluminum alloy door and window refers to door and window made of aluminum alloy extruded section as frame, vertical and fan materials, which is referred to as aluminum door and window. The aluminum alloy door and window includes door and window with aluminum alloy as force bar (rod that bears and transmits dead weight and load) base material and wood and plastic composite, which is referred to as aluminum-wood composite door and window and aluminum-plastic composite door and window. The main features of the aluminum alloy door and window are light, durable and corrosion-resistant, with high strength, capable of bearing large pressure, and light weight, which helps to reduce the burden of building structure.
[0003] When the aluminum alloy door and window is processed, it is usually necessary to cut it. The prior art generally cuts the aluminum alloy material by means of a high-speed rotating cutter head.

Similarly, the position of the aluminum alloy material close to the cut will also generate heat and be in a high-temperature state. The high-speed rotating cutter head needs to be applied with external force. Therefore, the aluminum alloy material in a high-temperature state will be slightly concave downward due to the action of external force, so that the end of the cut aluminum alloy material is in a non-horizontal state. When the aluminum alloy material is assembled and spliced into a door and window frame by artificial, it needs to be corrected by means of a tool, thereby affecting the assembly efficiency of the door and window frame.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.
[0019] The following describes an embodiment of the present invention based on its overall structure.
[0020] A cutting device for processing aluminum alloy doors and windows, such as Figures 1 to 9 As shown, the cutting machine comprises a cutting table 100 and a conveyor belt 500. The conveyor belt 500 is provided at one end of the cutting table 100 and is used to convey the aluminum alloy material to the cutting table 100 for cutting. A clearance groove 120 is provided in the center of the upper surface of the cutting table 100. A cutting assembly 300 for cutting the aluminum alloy material is installed in the clearance groove 120. An anti-deformation assembly 400 is installed on one side of the cutting assembly 300, located on the upper surface of the cutting table 100, to prevent deformation of the incision position of the aluminum alloy material. The deformation prevention assembly 400 comprises a board 410 arranged along the length direction of the cutting table 100, one end of the board 410 is fixed with a I-shaped head 430 abutting against the inner wall of the aluminum alloy material, the I-shaped head 430 is located at the center position of the cutting assembly 300, the upper surface of the I-shaped head 430 is rotatably provided with two groups of first rolling balls 431, the front and rear surfaces of the board 410 are fixed with edge strips 440, the surfaces of the edge strips 440 are arranged with second rolling balls 441 at equal intervals along the length direction of the edge strips 440, the other end of the board 410 abuts against an end plate 420 rotatably connected to the end surface of the cutting table 100, the end plate 420 is transversely provided with an insertion plate 480 extending into the end surface of the board 410, and the end surface of the board 410 is provided with a rectangular groove 470 at the position in contact with the insertion plate 480, and the upper portion of the board 410 is sleeved with a U-shaped baffle 460 connected to the upper surface of the cutting table 100; The cutting assembly 300 comprises a ring frame 310 fixed in the accommodation groove 120, a driven ring 340 rotatably arranged in the ring frame 310, the end surface of the driven ring 340 is provided with four groups of guide arc grooves 360 distributed along the circumferential direction of the driven ring 340, each group of guide arc grooves 360 comprises a non-extrusion area 361 and an extrusion area 362, the non-extrusion areas 361 and the extrusion areas 362 in the adjacent two groups of guide arc grooves 360 are arranged in a staggered manner, and the ring frame 310 is provided with a motor frame 381 on one side of each group of guide arc grooves 360, the output end of the motor frame 381 is connected with a cutter disc 382 through a rotating shaft, the rotating shaft passes through the guide arc groove 360 and extends to the outside of the ring frame 310, the outside of the motor frame 381 is provided with a second driving motor 380, the end surface of the second driving motor 380 is fixed with a positioning shaft 370 extending into the ring frame 310, and the inner wall of the ring frame 310 is provided with a long straight groove 390 at the position in contact with the positioning shaft 370; The cutting assembly 300 further comprises a first driving motor 330 assembled to the end surface of the ring cover 320 and having an output end extending into the ring frame 310, the output end of the first driving motor 330 is provided with a gear 350, and the outer wall of the driven ring 340 is fixed with a gear ring 341 engaged with the gear 350; The aluminum alloy material cut by the cutting assembly 300 forms a segmented aluminum alloy 450 and is sleeved outside the board 410; The front surface of the cutting table 100 is provided with a control console 110, the control console 110 is provided with a module capable of controlling the forward rotation and reverse rotation of the first driving motor 330, and the electric push rod 230 and the second driving motor 380 can be controlled to work through wires.
[0021] It is worth noting that the non-extrusion area 361 in the guide arc groove 360 coincides with the center of the ring frame 310, and the extrusion area 362 does not coincide with the center of the ring frame 310, for example, Figure 4As shown, when the driven ring 340 rotates clockwise, the extrusion areas 362 in the two sets of guide arc grooves 360 in the vertical direction approach (or rotate closer) toward the positioning shaft 370, and the extrusion areas 362 will squeeze the positioning shaft 370 to make it move radially (or move closer to the center of the ring frame 310), while the non-extrusion areas 361 of the two sets of guide arc grooves 360 in the horizontal direction are close to the positioning shaft 370. Therefore, the two sets of positioning shafts 370 in the horizontal direction will not move, and the outer side of the ring frame 310 and the corresponding cutter heads 382 move synchronously to cut the upper and lower surfaces of the aluminum alloy material; when the driven ring 340 rotates counterclockwise, the two sets of positioning shafts 370 in the vertical direction will not move, and the two sets of positioning shafts 370 in the horizontal direction will not move. 0 radially converges inward, thereby cutting the front and back surfaces of the aluminum alloy material. The I-head 430 is located on both sides of the incision position of the aluminum alloy material, and the grooves around the I-head 430 allow the cutter head 382 to completely cut one side of the aluminum alloy material (to prevent the positive corner position of the aluminum alloy material from being uncut). After two cuts, the cutting operation of the aluminum alloy material is completed. At the same time, it can support the aluminum alloy material at the incision position to prevent the incision position of the aluminum alloy material from deformation, thereby improving the cutting quality of the aluminum alloy material. The four sets of cutter heads 382 are all vertically close to the aluminum alloy, so the burrs generated by cutting are pointed inward, preventing workers from being injured when picking up for assembly. At the same time, there is no need to manually clean the burrs, which indirectly improves the assembly efficiency of door and window frames. like Figure 6 As shown, the aluminum alloy segments 450 slide toward the ends on the slats 410 under the push of the rear conveyor belt 500 (the conveyor belt 500 transports the long aluminum alloy material toward the cutting table 100, generating a thrust on the aluminum alloy segments 450), making them easier to remove for assembly into door and window frames. Furthermore, because one end of the I-head 430 is located within the aluminum alloy material to be cut, when the conveyor belt 500 transports the long aluminum alloy material, the aluminum alloy material can move directly to one side along the rectangular outline of the I-head 430. The I-head 430 guides the aluminum alloy material moving from the rear, allowing it to pass through the interior of the cutting assembly 300 and await the next cut. When cutting aluminum alloy materials, push the U-shaped baffle 460 to move on the top of the cutting table 100, so that the U-shaped baffle 460 is close to or away from the cutting assembly 300, and refer to the scale lines on the cutting table 100 to determine the cutting length of the aluminum alloy materials. Figure 6As shown, the U-shaped baffle 460 abuts against the end face of the segment-shaped aluminum alloy 450, and the main bearing point is the top of the I-beam 430, so the end of the segment-shaped aluminum alloy 450 in contact with the U-shaped baffle 460 after cutting will tilt downward and no longer abut, and the end close to the I-beam 430 will slightly lift upward. By arranging the first ball 431, the friction between the segment-shaped aluminum alloy 450 and the I-beam 430 is reduced, and the segment-shaped aluminum alloy 450 will slide onto the board strip 410. Since the thickness of the board strip 410 is smaller than the thickness of the I-beam 430, the segment-shaped aluminum alloy 450 will pass along the board strip 410 and through the channel in the U-shaped baffle 460, and the side strip 440 can abut against the inner side wall of the segment-shaped aluminum alloy 450, so that the segment-shaped aluminum alloy 450 will not deviate left and right when sliding outside the board strip 410, and then, under the cooperation of the second ball 441, the segment-shaped aluminum alloy 450 will be pushed to the end of the board strip 410. The plug plate 480 is manually pulled out and separated from the board strip 410 and the end plate 420, the end plate 420 is swung to be horizontal to the cutting table 100, and then the segment-shaped aluminum alloy 450 can be taken off.
[0022] Please refer to Figure 2 The bottom of the U-shaped baffle 460 is fixed with dovetail blocks, and the upper surface of the cutting table 100 is provided with dovetail grooves at the positions where each group of dovetail blocks contacts. The upper surface of the cutting table 100 is provided with a scale line on one side of the dovetail groove, and the size of the channel in the U-shaped baffle 460 is greater than the size of the aluminum alloy material.
[0023] When cutting the aluminum alloy material to a fixed size, the U-shaped baffle 460 can be linearly moved along the dovetail groove, and the cutting size of the aluminum alloy material can be accurately controlled by comparing with the scale line. The dovetail blocks can be fixed in the dovetail grooves by applying an external force to the fastening bolts with a tool, so that the U-shaped baffle 460 can be fixed above the U-shaped baffle 460 to block the end face of the aluminum alloy material. The cut segment-shaped aluminum alloy 450 can linearly move along the board strip 410, pass through the space between the U-shaped baffle 460 and the board strip 410, and approach the end of the board strip 410, which facilitates taking off the aluminum alloy material for assembly of the door and window frame.
[0024] Please refer to Figure 2 The anti-deformation assembly 400 further includes two groups of support tables fixed to the upper surface of the cutting table 100, and the two groups of support tables are respectively arranged below the board strip 410 and close to the positions near the two ends.
[0025] The support tables support the aluminum alloy material sleeved on the board strip 410, and can prevent the end of the board strip 410 connected to the I-beam 430 from tilting downward.
[0026] Please refer to Figure 3The cutting assembly 300 comprises a ring cover 320 connected with the end of the ring frame 310, the ring cover 320 is composed of two groups of arc-shaped ring plates and is fixed with the end surface of the ring frame 310 through bolts; The end surface of the ring cover 320 is provided with a plurality of groups of heat dissipation grooves for dissipating heat of the first driving motor 330.
[0027] By arranging the arc-shaped ring plates, the ring cover 320 can be loosened by a wrench or the like, so that the ring cover 320 is removed from the ring frame 310, and the internal parts or the first driving motor 330 can be disassembled and repaired.
[0028] Please refer to Figure 1 , Figure 8 and Figure 9 , the upper surface of the cutting table 100 is provided with a positioning jig 200 for clamping the aluminum alloy material, the positioning jig 200 is located on the side of the cutting assembly 300 away from the deformation prevention assembly 400, the positioning jig 200 comprises two groups of vertical arms 220 fixed on the upper surface of the cutting table 100, the top of the two groups of vertical arms 220 is fixed with a top plate 210, the bottom of the top plate 210 is provided with two groups of pressing strips 240 for extruding the aluminum alloy material along the length direction of the top plate 210, the two groups of pressing strips 240 are respectively located on the two sides of the vertical arms 220, and the top of the top plate 210 is provided with four groups of electric push rods 230 for pushing the pressing strips 240 to descend.
[0029] The lower surface of the top plate 210 is provided with two groups of positioning rods 270 inserted into the upper surface of the cutting table 100, the outer wall of each positioning rod 270 is sleeved with a driven roller 260, the top of the driven roller 260 is provided with a threaded cap 272 threadedly connected with the positioning rod 270, the outer wall of the positioning rod 270 is provided with a stepped ring groove 271 at the position in contact with the driven roller 260, and the upper surface of the cutting table 100 is provided with a plurality of groups of insertion holes at the position in contact with the positioning rod 270; The center position of the upper surface of the top plate 210 is provided with a roller group 250, and the diameters of the rollers in each group are different.
[0030] When the aluminum alloy material is cut, the telescopic end of the electric push rod 230 is extended and the pressing strip 240 is lowered until it is in contact with the aluminum alloy material, and the cutting table 100 fixes the aluminum alloy material; When different sizes of aluminum alloy materials are cut, the rollers can be selected according to the width of the aluminum alloy material to control the space between the two groups of driven rollers 260, and the size of the aluminum alloy material is adapted by replacing the insertion holes of the positioning rod 270 and the cutting table 100, and the deformation prevention assembly 400 is also replaced according to the need, thereby improving the applicability of the present application.
[0031] In use, the driven ring 340 rotates in two directions in turn, so that the cutter head 382 cuts the aluminum alloy material twice, and the burr tips generated by the cutting are directed inward (the burr tips are directed to the center of the end face of the aluminum alloy material), preventing the workers from being pricked when taking and assembling, and without manual burr cleaning, indirectly improving the assembly efficiency of the door and window frame; Figure 6 As shown, the segment-shaped aluminum alloy 450 will slide to the end on the board 410 under the pushing action of the rear conveying belt 500 (the conveying belt 500 conveys the long aluminum alloy material to the cutting table 100, and generates a pushing force on the segment-shaped aluminum alloy 450), facilitating manual removal for assembling the door and window frame; and since one end of the I-beam 430 is located in the aluminum alloy material to be cut, when the conveying belt 500 conveys the long aluminum alloy material, the aluminum alloy material can directly move along the rectangular profile of the I-beam 430 to one side, and the I-beam 430 can guide the aluminum alloy material moving rearward to pass through the cutting assembly 300 and wait for the next cutting; Although the embodiments of the present application have been shown and described, the specific embodiments are merely illustrative of the present application, and are not intended to limit the application, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
