[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention feeds the aluminum alloy profile into the lower part of the adjustable cutting structure through the cooperation of the feeding component, the supporting component and the auxiliary component, and at the same time drives the adjustable cutting structure to run through the cooperation of the cylinder and the adjustable cutting structure to wrap the part to be cut inside the adjustable cutting structure, and utilizes the cooperation of the adjustable cutting structure and the fixing component to drive the fixing component to move downward to press the aluminum profile downward to limit its vertical movement, and simultaneously utilizes the cooperation of the fixing component and the feeding component to drive the feeding component to rise, and simultaneously utilizes the cooperation of the feeding component and the linkage component to drive the auxiliary component to press inward to limit its horizontal movement, so as to avoid the position displacement of the profile during the cutting process and improve the cutting accuracy.

[0019] 2. The present invention drives the shielding cover to descend through the action of the cylinder and the shielding cover, so that it covers the vicinity of the cutting point of the aluminum alloy profile. The shielding cover and the fire-resistant curtain prevent the debris cut from the aluminum profile from splashing and causing damage to personnel and other equipment. At the same time, the connecting groove collects the debris into the waste slag box to facilitate subsequent cleaning.

[0020] 3. The present invention also utilizes the cooperation between the compression spring 6 in the installation groove and the slider 2 to clamp the rotating disk at a specific angle through the limit groove, so that the circular saw installed on the lower side of the support frame 3 and the profile are maintained at a predetermined angle, which is convenient for adjusting the cutting angle and meeting the cutting requirements at different angles.

[0021] 4. The present invention supports the aluminum profiles of doors and windows from the bottom through the action of roller one, and during the supporting process, limits them from both sides through auxiliary components installed on the fixed plates on both sides, so as to avoid the horizontal angle of the profile from being offset when the feeding component is running to feed the material inward, thereby reducing the influence on the accuracy of the cutting angle. At the same time, the friction wheel, roller one and roller three on both sides are used to feed the material inward, and the profile to be cut is sent into the range of the shielding cover. After the cutting is completed, the feeding components on both sides are used to send out the cut profile, and new materials are sent into the range of the shielding cover to achieve continuous processing.

[0022] 5. In the process of the support frame three moving downward, the present invention simultaneously drives the T-shaped rod two to move downward through the connecting rod two, thereby prompting the compression block to press on the upper side of the aluminum profile, and simultaneously utilizes the action of the connecting rod one and the T-shaped relay block to drive the T-shaped relay block to rise. At this time, the wedge blocks on both sides are driven to slide downward along the fixed plate under the cooperation of the T-shaped relay block and the linkage components on both sides, thereby pushing the installation frame to approach the aluminum profile, so that the roller three is attached to the side wall of the aluminum profile, thereby limiting the horizontal and vertical directions of the aluminum profile, avoiding the position displacement of the aluminum profile due to the friction contact of the saw blade during cutting, thereby avoiding affecting the flatness of the cutting surface, and further avoiding the profile bouncing up caused by cutting, causing other safety accidents.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1 As shown, a cutting device for processing aluminum alloy doors and windows includes a base 1, a support frame 4 is fixedly connected to the middle of the upper end of the base 1, a cylinder 3 is fixedly connected to the upper end of the support frame 4, a piston rod at the output end of the cylinder 3 passes through the upper end of the support frame 4 and extends to the lower end of the support frame 4 and is provided with an adjustable cutting structure 5, a control console 6 is fixedly connected to the front end of the support frame 4, and a fixed feeding structure 2 fixedly connected to the adjustable cutting structure 5 is symmetrically provided on the upper end of the base 1.

[0036] It should be noted that the above-mentioned control console 6 is a conventional controller, which is mainly used to control the start and stop of the internal motor and the extension and retraction of the cylinder 3. It is a conventional technical means in the prior art. In the present invention, it is only used to control the operation of the equipment, and its internal wiring method and control method are not elaborated in detail.

[0037] Specifically, to achieve the feeding, limiting and fixing of aluminum alloy door and window profiles, refer to Figure 2The fixed feeding structure 2 includes a U-shaped support frame 21 fixedly connected to one side of the upper end of the base 1, and a fixing component 23 fixedly connected to the support frame 3 51 is arranged on one side of the support frame 21 close to the support frame 3 51, and a feeding component 22 is arranged at the front and rear ends of the fixing component 23 and the horizontal part of the support frame 21, and a symmetrically distributed linkage component 25 is arranged at the left and right ends of the feeding component 22 and the lower end of the horizontal part of the support frame 21, and a support component 24 is arranged at the upper end of the base 1 at the lower side of the horizontal part of the support frame 21, and auxiliary components 26 that are closely attached to the linkage component 25 on the same side are symmetrically arranged on the inner side of the support component 24.

[0038] The support frame 21 is mainly used to provide an installation place and support for other structures. The feeding component 22 arranged at the lower part of the support frame 21 is in contact with the upper part of the aluminum alloy profile in the initial state. Driven by the internal motor, the profile can be driven to slide on the upper side of the support component 24. At the same time, the auxiliary components 26 on both sides can limit the feeding direction of the aluminum alloy profile to reduce the deviation of the profile during feeding. At the same time, the fixing component 23 is mainly used to fix the profile during cutting to avoid the deviation of the profile due to cutting vibration, which affects the flatness of the cutting surface.

[0039] During the operation of this embodiment, the aluminum alloy profile is first fed into the lower part of the adjustable cutting structure 5 through the cooperation of the feeding component 22, the supporting component 24, and the auxiliary component 26. At the same time, the adjustable cutting structure 5 is driven to run through the cooperation of the cylinder 3 and the adjustable cutting structure 5 to wrap the part to be cut inside the adjustable cutting structure 5. The adjustable cutting structure 5 is driven to move the fixing component 23 downward by the cooperation of the fixing component 23 and the feeding component 22 to press the feeding component 22 downward to limit its vertical movement. The feeding component 22 is driven to rise by the cooperation of the linkage component 25 and the auxiliary component 26 is driven to press inward to limit its horizontal movement to avoid position displacement of the profile during the cutting process and improve the cutting accuracy.

[0040] Embodiment 2: Based on Embodiment 1, the shielding cover 52 is driven to descend by the action of the cylinder 3 and the shielding cover 52, so that it covers the vicinity of the cutting point of the aluminum alloy profile. The shielding cover 52 and the fire-resistant curtain 53 are used to isolate the aluminum profile from the debris cut off from splashing, causing damage to personnel and other equipment. At the same time, the connecting groove 57 is used to collect the debris into the waste slag box 56, which is convenient for subsequent cleaning.

[0041] In addition, by utilizing the cooperation between compression spring six 546 in the installation slot 543 and slider two 545, the rotating disk 541 is locked at a specific angle through the limit slot 542, so that the circular saw 59 installed on the lower side of the support frame three 51 is maintained at a predetermined angle with the profile, making it convenient to adjust the cutting angle to meet the cutting requirements at different angles.

[0042] Specifically, to achieve the cutting of aluminum alloy door and window profile raw materials, refer to Figure 3 The adjustable cutting structure 5 includes a support frame 3 51 fixedly connected to the piston rod at the output end of the cylinder 3. The left and right sides of the support frame 3 51 are fixedly connected to the fixed feeding structure 2 on the same side. The lower end of the support frame 3 51 is fixedly connected to a shielding cover 52. The upper end of the shielding cover 52 is provided with an adjusting component 54. The upper end of the adjusting component 54 is fixedly connected to a driving motor 55. The lower end of the adjusting component 54 is fixedly installed with a circular saw 59 through a bearing bracket. The driving shaft of the circular saw 59 is connected to the output end of the driving motor 55 through a belt drive.

[0043] After the piston rod of the cylinder 3 extends outward, it will drive the support frame 3 51 and the shielding cover 52 connected thereto to descend. A slot is provided on the upper side of the base 1 for the shielding cover 52 to pass through. The shielding cover 52 can gradually descend until the circular saw 59 completely cuts through the aluminum profile. The circular saw 59 is driven by the drive motor 55 and can rotate rapidly inside the shielding cover 52, thereby cutting off the aluminum alloy tube profile from a predetermined position.

[0044] Furthermore, in order to achieve the shielding and collection of waste and splashing debris generated by cutting, refer to Figure 4 The adjustable cutting structure 5 also includes a plurality of connecting grooves 57 opened in the middle of the upper end of the base 1, and a plurality of fire-resistant curtains 53 are linearly distributed and fixedly connected to the left and right parts of the inner surface of the shielding cover 52. The upper end of the base 1 located on the left and right sides of the connecting groove 57 is fixedly connected to support rollers 58, and the lower end of the base 1 located below the connecting groove 57 is slidably connected to a waste slag box 56 through a slide.

[0045] The support roller 58 is mainly used to place the profile fed by the fixed feeding structure 2 on the lower side of the shielding cover 52, so that its cutting point is suspended on the upper part of the connecting groove 57. After the shielding cover 52 covers the vicinity of the profile cutting point, the fire-resistant curtain 53 naturally droops to cover the left and right sides of the profile cutting position. When the circular saw 59 moves downward under the action of the shielding cover 52 and the support frame 51 to cut the profile, the waste residue generated by the cutting will move along the tangent direction of the circular saw 59 and hit the inner wall of the shielding cover 52, and finally fall downward through the connecting groove 57 into the waste residue box 56, which is convenient for subsequent operators to clean up and avoids splashing of debris to cause injuries to operators.

[0046] Further, to adjust the cutting angle, refer to Figure 4 and Figure 5The adjustment component 54 includes a rotating disk 541 rotatably connected to the upper end of the shielding cover 52, and the driving motor 55 and the circular saw 59 are both installed on the rotating disk 541. The upper end of the shielding cover 52 is provided with a plurality of mounting grooves 543 distributed in a fan shape along the rear part of the outer surface of the rotating disk 541, and the sides of the plurality of mounting grooves 543 away from the rotating disk 541 are fixedly connected with compression springs 6 546, and the sides of the plurality of compression springs 6 546 close to the rotating disk 541 are fixedly connected with sliders 2 545 slidably connected to the inner surfaces of the adjacent mounting grooves 543, and the upper ends of the plurality of sliders 2 545 are fixedly connected with pull rings 544, and one side of the outer surface of the rotating disk 541 is provided with a limiting groove 542 with the same width as the pull ring 544.

[0047] If the rotating disk 541 is not limited by the second slider 545, it can rotate on the upper part of the shielding cover 52. Since the driving motor 55 and the circular saw 59 are both installed on the rotating disk 541, they can rotate synchronously with the action of the rotating disk 541, so that the circular saw 59 can present different angles relative to the profile.

[0048] When one of the sliders 545 is in the limiting groove 542, the rotating disk 541 cannot rotate. At this time, the angle is fixed at the relative angle where the slider 545 is located. The slider 545 can be pulled out of the limiting groove 542 by the pull ring 544. At this time, the rotating disk 541 can rotate. The opening angle of the mounting groove 543 is different according to different needs. Generally, the cutting angle is basically 45 degrees and 90 degrees. The effects of three angles of 45 degrees to the left, 45 degrees to the right and 90 degrees are shown in the accompanying drawings. Other opening positions are determined by actual production needs and are no longer shown in the present invention.

[0049] Embodiment 3: Based on Embodiment 2, this embodiment further supports the aluminum profiles of the alloy doors and windows from the bottom through the action of roller 1 242, and during the supporting process, it is simultaneously limited from both sides by the auxiliary components 26 installed on the fixed plates 243 on both sides, so as to avoid the horizontal angle of the profile from being offset during the operation of the feeding component 22 to feed the material inward, thereby reducing the influence on the accuracy of the cutting angle. At the same time, the friction wheel 224, roller 1 242 and rollers 3 262 on both sides are used to feed the material inward, and the profile to be cut is sent into the range of the shielding cover 52. After the cutting is completed, the cutting profile is sent out by the action of the feeding components 22 on both sides, and the new material is sent into the range of the shielding cover 52 to realize continuous processing.

[0050] Specifically, to achieve the support of aluminum alloy door and window profiles, refer to Figure 6The support component 24 includes a fixed plate 243 that is symmetrically distributed on the left and right and fixedly connected to the upper end of the base 1. The ends of the two fixed plates 243 that are close to each other are commonly fixedly connected with two central shafts 241 that are symmetrically distributed on the left and right. The middle parts of the outer surfaces of the two central shafts 241 are symmetrically rotated front and back and connected with a roller 242. The outer surfaces of the two central shafts 241 and the inner surfaces of the fixed plates 243 on both sides are slidably connected to the auxiliary component 26.

[0051] The center shaft 241 is mainly used to install roller 1 242 and simultaneously limit the auxiliary component 26. The outer surface of roller 1 242 fits the lower end of the aluminum alloy profile and is used to follow the movement and rotation of the profile to assist the upper feeding component 22 to feed inward or outward.

[0052] Further, to achieve inward feeding, see Figure 7 The feeding assembly 22 includes a compression spring 222 fixedly connected to the lower end of the horizontal part of the support frame 21, the lower end of the compression spring 222 is fixedly connected to a T-shaped relay block 223, the upper end of the T-shaped relay block 223 is fixedly connected to a T-shaped rod 221, the upper end of the T-shaped rod 221 passes through the lower end of the horizontal part of the support frame 21 and extends to the upper end of the support frame 21, the left and right ends of the T-shaped relay block 223 are both rotatably connected to a connecting rod 225, and the two connecting rods 225 are away from the T-shaped relay One end of the block 223 is rotatably connected to the adjacent end surface of the pressure plate 235, and the middle parts of the two connecting rods 225 close to each other are rotatably connected to a support rod fixedly connected to the lower end of the mounting rod 231. The lower left and right ends of the vertical part of the T-shaped relay block 223 are symmetrically rotatably connected to the friction wheel 224. A small motor is arranged inside the T-shaped relay block 223 to drive the friction wheel 224 to rotate, and the left and right ends of the horizontal part of the T-shaped relay block 223 are rotatably connected to the linkage assembly 25 on the same side.

[0053] The connecting rod 225 is retractable, and forms a seesaw-like structure through the support rod. When the fixed component 23 rises, it drives the T-shaped relay block 223 to descend. At this time, the friction wheel 224 fits with the upper end of the aluminum alloy profile. When the internal motor rotates, the friction wheel 224 rotates to drive the profile to move toward the adjustable cutting structure 5 or move the cut profile away from the adjustable cutting structure 5.

[0054] Synchronously, when the T-shaped relay block 223 descends, it will drive the linkage assembly 25 to run and release the limit on the auxiliary assembly 26. At this time, the auxiliary assembly 26 fits against the side wall of the aluminum profile, and when the friction wheel 224 rotates to feed the material, it limits the profile from both sides to reduce its deviation.

[0055] It should be noted that the above-mentioned small motor is a conventional driving component in the prior art, which can drive other components to rotate and is a mature technical means in the prior art. Its specific installation method, structure, and wiring method will no longer be displayed and explained in the present invention.

[0056] Further, in order to limit and position the aluminum profile from both sides during feeding, refer to Figure 6 and Figure 8 The auxiliary component 26 includes an installation frame 261 that is slidably connected to the outer surfaces of the two central shafts 241 through a connecting block, and a roller three 262 is symmetrically connected to the inner surface of the installation frame 261 for rotation. The end of the installation frame 261 away from the roller three 262 is symmetrically fixedly connected to the limit rod two 267 that is slidably connected to the inner surface of the fixed plate 243 on the same side. The ends of the two limit rods 267 away from the installation frame 261 both penetrate the proximal end of the fixed plate 243 on the same side and extend to the distal end of the fixed plate 243 and are fixedly connected to a compression spring five 268 fixedly connected to the fixed plate 243. The end of the fixed plate 243 close to the installation frame 261 is slidably connected to a wedge block 266, and the top wall of the inner surface of the wedge block 266 is fixedly connected to a compression spring four 264 fixedly connected to the fixed plate 243. The upper end of the wedge block 266 is tightly attached to the lower part of the adjacent striker 258, and a contact wheel 263 is fixedly installed on one side of the installation frame 261 close to the wedge block 266 through a bracket.

[0057] In the initial state, the linkage assembly 25 does not act on the wedge block 266. When the profile enters between the installation frames 261 on both sides, its side wall will fit with the roller three 262 and drive the roller three 262 to rotate in the process of gradually moving toward the adjustable cutting structure 5. In this process, the aluminum alloy profile is kept in the center position by the action of the compression spring five 268 to reduce its position deviation.

[0058] Embodiment 4. Based on embodiment 3, this embodiment drives T-bar 232 downward through connecting rod 234 during the downward movement of support frame 3 51, thereby prompting compression block 236 to press on the upper side of the aluminum profile, and simultaneously utilizes the action of connecting rod 1 225 and T-shaped relay block 223 to drive T-shaped relay block 223 to rise. At this time, with the cooperation of T-shaped relay block 223 and linkage components 25 on both sides, wedge blocks 266 on both sides are driven to slide downward along fixed plate 243, thereby pushing mounting frame 261 to approach aluminum profile, so that roller 3 262 fits against the side wall of aluminum profile, thereby limiting the horizontal and vertical directions of aluminum profile, avoiding position displacement of aluminum profile due to friction contact of saw blade during cutting, thereby avoiding affecting the flatness of cutting surface, and further avoiding profile bouncing caused by cutting, causing other safety accidents.

[0059] Specifically, in order to achieve the compression and fixation of the aluminum profile during the cutting process, refer to Fig. 9 and Fig.10 The fixing assembly 23 includes a mounting rod 231 fixedly connected to the middle part of one side of the horizontal part of the support frame 1 21 close to the support frame 3 51, a compression spring 233 is fixedly connected to the upper end of the mounting rod 231, a T-shaped rod 232 is fixedly connected to the upper end of the compression spring 233, a vertical portion of the T-shaped rod 232 passes through the upper end of the mounting rod 231 and extends to the lower end of the mounting rod 231 and is fixedly connected to a compression block 236, a pressing plate 235 is fixedly connected to the upper part of the outer surface of the vertical portion of the T-shaped rod 232, and a portion of the outer surface of the T-shaped rod 232 located above the pressing plate 235 is slidably connected to a connecting rod 234 fixedly connected to the adjacent end surface of the support frame 3 51.

[0060] When the T-shaped rod 232 descends, the T-shaped relay block 223 is driven to rise. At this time, the cooperation between the T-shaped relay block 223 and the linkage components 25 on both sides drives the auxiliary component 26 to operate, thereby auxiliary limiting the side walls of the profile from both sides to reduce the front and rear deviation of the profile.

[0061] When the support frame 3 51 descends, the connecting rod 234 will be used to drive the T-shaped rod 232 to descend. At this time, the pressing block 236 follows the T-shaped rod 232 to descend until it fits with the upper part of the profile, and the profile is pressed and fixed;

[0062] The height of the pressing block 236 is determined according to the type of the profile. When the connecting rod 225 is in a horizontal state, the lower end of the pressing block 236 is tangent to the bottom of the friction wheel 224.

[0063] Further, in order to cooperate with the relative movement of the fixing assembly 23 and the feeding assembly 22 to drive the auxiliary assembly 26 to clamp inwardly, refer to Figure 6 and Figure 7 The linkage assembly 25 includes a horizontal groove 252 opened at the lower end of the horizontal part of the support frame 21 and a vertical groove 251 connected to the tail end of the horizontal groove 252 and fixedly connected to the lower end of the support frame 21, the inner surfaces of the vertical groove 251 and the horizontal groove 252 are both slidably connected with roller two 253, the inner surfaces of the two rollers two 253 are rotatably connected with a connecting rod three 254, the inner surface of the roller two 253 close to the T-shaped relay block 223 is rotatably connected with a connecting rod four 255 rotatably connected to the end surface of the horizontal part of the adjacent T-shaped relay block 223, the inner surface of the vertical groove 251 is slidably connected with a slider one 256 that fits the roller two 253, the lower end of the slider one 256 is fixedly connected with a compression spring three 257 that is fixedly connected to the bottom wall of the inner surface of the vertical groove 251, and the lower end of the slider one 256 is fixedly connected with a striker 258 that penetrates the bottom wall of the inner cavity of the vertical groove 251, extends to the lower end of the vertical groove 251 and is tightly attached to the auxiliary assembly 26.

[0064] When the T-shaped rod 232 descends, the T-shaped relay block 223 rises, thereby pushing the upper roller 253 to slide in the horizontal groove 252 through the connecting rod 4 255. At this time, under the action of the roller 253, the connecting rod 3 254 pushes the roller 253 located in the vertical groove 251 to slide downward in the vertical groove 251. In this way, the roller 253 will press the slider 1 256 to slide downward in the vertical groove 251, thereby pushing the striker 258 to move downward. At this time, the striker 258 will push the wedge block 266 to slide downward along the fixing plate 243. Through the action of the wedge block 266 and the contact wheel 263, the installation frame 261 is pushed to approach the aluminum profile along the direction of the limiting rod 267. At this time, the roller 3 262 is pressed on the surface of the aluminum profile, and its front and rear directions are limited by the installation frame 261 and the roller 3 262 on both sides, thereby achieving the fixation of the aluminum profile during the cutting process.
