An aluminum profile cutting device

Abstract

This invention relates to the field of aluminum profile cutting technology. An aluminum profile cutting device includes a worktable with a backing plate fixedly connected to its upper surface. Cutting holes are provided on the worktable, and a gantry frame is fixedly connected to its upper surface. A lifting mechanism is mounted on the gantry frame, and a cutting mechanism that works in conjunction with the cutting holes is mounted on the lifting mechanism. A length-fixing device and a feeding device are provided on the worktable. This invention uses an electric push rod to drive a liquid storage cylinder downwards. On one hand, this causes the anti-slip ring on the length-fixing ring to contact the upper surface of the aluminum profile, using friction to drive the length-fixing ring to rotate and achieve length measurement. On the other hand, the continuous thrust output by the electric push rod presses the aluminum profile against the worktable, effectively limiting the upward warping deformation of the aluminum profile caused by the saw blade cutting force during the cutting process. One set of actions simultaneously achieves two functions, realizing integrated "measurement and marking" functionality, providing intuitive positioning reference for quality traceability and subsequent processes.

Description

Technical Field

[0001] This invention belongs to the field of aluminum profile cutting technology, and specifically relates to an aluminum profile cutting device. Background Technology

[0002] Aluminum profiles are widely used in building doors and windows, curtain walls, industrial frames, transportation, and electronic appliances due to their advantages such as light weight, high strength, and corrosion resistance. In the processing of aluminum profiles, cutting is one of the basic and key processes, and the cutting accuracy and efficiency directly affect the subsequent assembly quality and production costs.

[0003] In existing technologies, aluminum profile cutting devices are mainly divided into two categories: semi-automatic and fully automatic. Semi-automatic cutting devices have a ruler and a positioning plate (commonly known as a "backing plate") set on the worktable. The operator places the end of the aluminum profile against the backing plate, aligns it with the ruler scale, confirms the length, and then manually starts cutting. This type of solution relies on manual reading of the ruler scale, which is subject to subjective errors and makes it difficult to guarantee the consistency of cutting accuracy. The cutting position cannot be visually marked on the profile surface, making quality untraceable and lacking intuitive basis when multiple people are working together to confirm the cut. The operator must be close to the cutting area, which poses a safety hazard.

[0004] Fully automatic cutting devices use electronic or mechanical measuring devices to automatically measure the moving length of aluminum profiles. Once the preset length is reached, cutting is automatically triggered. This type of solution usually requires the use of controllers, sensors, and drive components to achieve automatic cutting. The equipment cost is high, and it has stringent requirements for the operating environment (dust, temperature, vibration, etc.). Its reliability decreases in harsh environments such as construction sites.

[0005] In summary, although existing aluminum profile cutting devices have the function of fixed-length cutting, they still have the following shortcomings: semi-automatic solutions rely on manual reading, which has errors and safety hazards; fully automatic solutions have high equipment costs and poor environmental adaptability; and neither type of solution can form a visual and traceable cutting position mark on the surface of the aluminum profile while measuring the length. Summary of the Invention

[0006] The purpose of this invention is to provide an aluminum profile cutting device with a simple structure and reasonable design in order to solve the above problems.

The two ends of the spring are fixedly connected to the sides of the support plate and the sealing frame that are close to each other. An auxiliary component is provided between the sliding rod and the liquid storage cylinder.

[0012] As a further optimization of the present invention, the auxiliary component includes a first step block fixedly connected to the other end of the two slide rods, a support frame fixedly connected to one end of the support rod, the support frame being rotatably and sealingly connected to the side wall of the liquid storage cylinder, and a second step block fixedly connected to the support frame, the first step block and the second step block being used in conjunction.

[0013] As a further optimization of the present invention, a plurality of evenly distributed ball bearings are rolled on the second step block, and the ball bearings are spherical objects made of stainless steel.

[0014] As a further optimization of the present invention, the feeding assembly includes a motor fixedly connected to a fixed plate, a screw rotatably connected between the two fixed plates, the output end of the motor being fixedly connected to one end of the screw, a threaded sleeve being threaded onto the screw, a slide bar being fixedly connected onto the threaded sleeve, a sliding groove being provided on the worktable, the slide bar being slidably connected to the sliding groove, and the clamping assembly being mounted on the slide bar.

[0015] As a further optimization of the present invention, the clamping assembly includes a clamping box fixedly connected to a slide bar. Multiple evenly distributed locking blocks (I) are slidably connected to the surface of the clamping box. A connecting plate is fixedly connected to all locking blocks (I). Multiple evenly distributed springs (II) are fixedly connected to the connecting plate and the clamping box. A push plate is fixedly connected to the connecting plate and slidably connected to the clamping box. A protective strip is fixedly connected to the push plate and the clamping box. Two symmetrically arranged guide rods are fixedly connected to the side wall of the clamping box. A clamping plate (L-shaped) is slidably connected between the two guide rods. Springs (III) are sleeved on the guide rods. The two ends of the springs (III) are fixedly connected to the sides of the guide rods and the clamping plate that are close to each other. Multiple evenly distributed locking blocks (II) are fixedly connected to the clamping plate. The locking blocks (I) and locking blocks (II) are interleaved. An anti-slip pad is fixedly embedded in the clamping plate. A guide assembly is provided on the clamping plate.

[0016] As a further optimization of the present invention, the guide component includes a triangular strip fixedly connected to the clamping plate, the triangular strip being a right triangle with its inclined surface facing the clamping box.

[0017] The beneficial effects of this invention are as follows: 1. This invention integrates fixed-length measurement and clamping anti-warping functions into a single device. The liquid storage cylinder is driven to descend by an electric push rod. On one hand, the anti-slip ring on the fixed-length ring contacts the upper surface of the aluminum profile, and the friction force drives the fixed-length ring to rotate to achieve length measurement. On the other hand, the continuous thrust output by the electric push rod presses the aluminum profile against the worktable, effectively limiting the upward warping deformation of the aluminum profile caused by the cutting force of the saw blade during the cutting process. One set of actions achieves two functions simultaneously, eliminating the need for separate measurement and clamping mechanisms.

[0018] 2. This invention uses a purely mechanical friction transmission method to achieve length measurement, and automatically forms a cutting position mark on the surface of the aluminum profile through a marking component. Every time the liquid storage cylinder rotates, step block one and step block two contact once, driving the marking block to extend from the rectangular frame and leave a marking liquid mark on the surface of the aluminum profile. This mark is related to the number of rotations of the fixed length ring, and the distance between adjacent marks is equal to the circumference of the fixed length ring, realizing the integrated function of "measurement is marking". The cutting position is clearly visible, which is convenient for the operator to visually confirm. At the same time, the mark is left on the surface of the profile, providing an intuitive positioning reference for quality traceability and subsequent processes (such as drilling and welding).

[0019] 3. The length-fixing device of the present invention uses the friction between the anti-slip ring and the aluminum profile to drive the length-fixing ring to rotate. The length of the aluminum profile is measured by the circumference of the length-fixing ring, and the marking action is triggered by the mechanical cooperation of step block one and step block two. No electronic components such as encoders, sensors, and controllers are required throughout the process. Compared with the fully automatic electronic metering schemes in the prior art that rely on controllers and sensors, the equipment cost is greatly reduced.

[0020] 4. The fixed-length ring of the present invention has a preset circumference. The operator can select fixed-length rings with different circumferences or design different transmission ratios according to actual processing needs, thereby adjusting the spacing between the marks on the aluminum profile surface and realizing rapid switching of different cutting lengths. Compared with the scale / baffle scheme in the existing semi-automatic cutting device (which requires manual reading or adjustment of the baffle position), the present invention does not require repeated measurement or adjustment, making the operation simpler and more efficient. Compared with the fully automatic scheme (which requires resetting the controller parameters), the present invention can complete the length adjustment without professional electrical control personnel, making it more universal.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] For examples, please refer to Figures 1-11 An aluminum profile cutting device includes a worktable 1, a backing plate 101 fixedly connected to the upper surface of the worktable 1, a cutting hole 102 on the worktable 1, a gantry frame 2 fixedly connected to the upper surface of the worktable 1, a lifting mechanism 201 on the gantry frame 2, and a cutting mechanism 202 that cooperates with the cutting hole 102 on the lifting mechanism 201; a length fixing device 3 and a feeding device 4 are provided on the worktable 1; the length fixing device 3 includes a guide rail 301 fixedly connected to the upper surface of the worktable 1, a slider 302 slidably connected to the inner wall of the guide rail 301, a driving assembly fixedly connected to the upper surface of the worktable 1, the driving assembly being symmetrically arranged with the guide rail 301, a liquid storage assembly between the slider 302 and the driving assembly, and a length fixing assembly and a marking assembly on the liquid storage assembly; the feeding device 4 includes two fixing plates 401 fixedly connected to the lower surface of the worktable 1, a feeding assembly between the two fixing plates 401, and a clamping assembly on the feeding assembly.

[0025] In this embodiment, the operator places the aluminum profile on the workbench 1, initially positioning it so that its side is against the backing plate 101. The aluminum profile is then clamped and fixed by the clamping assembly on the feeding device 4. Next, the length-fixing device 3 is activated. The driving assembly in the length-fixing device 3 lowers the liquid storage assembly, bringing the length-fixing assembly on the liquid storage assembly into contact with the upper surface of the aluminum profile. Then, the feeding device 4 is activated. The feeding assembly in the feeding device 4 moves the clamping assembly and the aluminum profile toward the cutting mechanism 202. As the aluminum profile moves, the length-fixing assembly rotates along with it. The number of moving coils measures the moving length of the aluminum profile. At the same time, the marking component on the liquid storage component forms a cutting position mark on the surface of the aluminum profile. When the mark on the surface of the aluminum profile moves to the cutting position, the feeding device 4 is stopped and the lifting mechanism 201 is started. The lifting mechanism 201 drives the cutting mechanism 202 to descend. The circular saw blade in the cutting mechanism 202 enters the cutting hole 102 and performs a rotating circular cut on the aluminum profile. After the cut is completed, the lifting mechanism 201 drives the cutting mechanism 202 to rise and reset. The feeding device 4 continues to feed material and repeats the above marking and cutting process until the entire aluminum profile is cut.

[0026] It should be noted that both the lifting mechanism 201 and the cutting mechanism 202 are existing technologies and will not be described in detail here.

[0027] Please see Figures 3-8The drive assembly includes two support rods 305. One end of one support rod 305 is fixedly connected to the slider 302. An electric push rod 303 is fixedly connected to the upper surface of the worktable 1. A base block 304 is fixedly connected to the output end of the electric push rod 303. The base block 304 is fixedly connected to one end of the other support rod 305. A liquid storage assembly is installed between the two support rods 305. The liquid storage assembly includes a liquid storage cylinder 306 rotatably connected between the two support rods 305. An inlet is provided on the liquid storage cylinder 306. The liquid inlet 307 is threaded with a sealing plug 308. Both the length-fixing assembly and the marking assembly are mounted on the liquid storage cylinder 306. The length-fixing assembly includes two symmetrically fixed length rings 309 fixedly connected to both sides of the liquid storage cylinder 306, with anti-slip rings 310 embedded in each ring. The marking assembly includes a rectangular frame 311 fixedly connected to the liquid storage cylinder 306, with a sealing frame 312 slidably connected to the inner wall of the rectangular frame 311. A support plate 313 is fixedly connected to the inner wall of the liquid storage cylinder 306. The support plate 313 and the sealing frame 312 are slidably connected by two symmetrically arranged slide rods 314. One end of each slide rod 314 is fixedly connected to a square plate 315. A marking block 316 is fixedly connected between the two square plates 315. The marking block 316 is slidably connected to the rectangular frame 311. A spring 317 is sleeved on each slide rod 314. The two ends of the spring 317 are fixedly connected to the adjacent sides of the support plate 313 and the sealing frame 312, respectively. The slide rod 314 and the liquid storage cylinder 306 are connected together. An auxiliary component is provided between the two slide bars 314. The auxiliary component includes a step block 318 fixedly connected to the other end of the two slide bars 314. A support frame 319 is fixedly connected to one end of a support rod 305. The support frame 319 is rotatably connected to the side wall of the liquid storage cylinder 306. A step block 320 is fixedly connected to the support frame 319. The step block 318 and the step block 320 are used together. Multiple evenly distributed balls 321 are rolled on the step block 320. The balls 321 are spherical objects made of stainless steel.

[0028] In this embodiment, initially, the electric push rod 303 is in a retracted state, and the liquid storage cylinder 306 is located above the workbench 1. When cutting is required, the electric push rod 303 is activated, and its output end extends and pushes the base block 304. The base block 304 drives the support rod 305 connected to it to move upward. Since the other support rod 305 is slidably connected to the guide rail 301 through the slider 302, the two support rods 305 synchronously drive the liquid storage cylinder 306 to rise and fall smoothly. When the liquid storage cylinder 306 rises to its highest position, the aluminum profile is cut... Place it on the workbench 1 and let the aluminum profile abut against the backing plate 101. At this time, according to the size of the aluminum profile, drive the output end of the electric push rod 303 to retract, thereby driving the liquid storage cylinder 306 to descend to the workbench 1 until the anti-slip ring 310 on the fixed length ring 309 contacts the upper surface of the aluminum profile and applies a preset pressure. This pressure, on the one hand, generates sufficient static friction between the anti-slip ring 310 and the surface of the aluminum profile, and on the other hand, presses the aluminum profile against the workbench 1, limiting the upward warping deformation that may occur in the subsequent cutting process. In the initial state, spring 317 (tension spring) causes the port of sealing frame 312 to abut against the lower surface of support plate 313, forming a seal between sealing frame 312 and support plate 313, preventing the marking liquid in storage cylinder 306 from flowing into rectangular frame 311 and marking block 316, thereby preventing leakage of marking liquid when necessary. When feeding device 4 moves aluminum profile forward, the friction between the surface of aluminum profile and anti-slip ring 310 drives fixed length ring 309 to rotate, and fixed length ring 309 drives storage cylinder 306 to rotate synchronously. During the rotation of the liquid storage cylinder 306, the first step block 318 fixed on the slide rod 314 revolves with the liquid storage cylinder 306. When the first step block 318 rotates to contact the second step block 320 on the support frame 319, the reaction force of the second step block 320 pushes the first step block 318 outward. The first step block 318 drives the slide rod 314 and the square plate 315 to slide, overcoming the tension of the first spring 317, causing the slide rod 314 to drive the sealing frame 312 to move downward. The port of the sealing frame 312 leaves the lower surface of the support plate 313, and the seal is closed. Released, the marking liquid in the reservoir 306 flows from the port of the sealing frame 312 into the rectangular frame 311, and then through the rectangular frame 311 to the marking block 316. The marking block 316 is soaked in the marking liquid. At the same time, the square plate 315 pushes the marking block 316 out of the rectangular frame 311 to contact the surface of the aluminum profile. The marking liquid on the marking block 316 leaves a cutting position mark on the surface of the aluminum profile. The ball bearings 321 provided on the second step block 320 can reduce the frictional resistance when in contact with the first step block 318, ensuring smooth transmission. As the liquid storage cylinder 306 continues to rotate, when step block 318 separates from step block 320, spring 317 resets and pulls the sealing frame 312 upward, causing the port of the sealing frame 312 to re-attach to the lower surface of the support plate 313, restoring the seal and preventing the marking liquid from continuing to flow out. At the same time, the slide bar 314 drives the marking block 316 to retract into the rectangular frame 311, completing one complete marking action. The above process is repeated once for each rotation of the liquid storage cylinder 306, thereby forming equally spaced cutting position marks on the surface of the aluminum profile.

[0029] It should be noted that the anti-slip ring 310 is made of polyurethane foam to increase the friction between the fixed-length ring 309 and the aluminum profile; the spring 317 is a stainless steel spring; the circumference of the fixed-length ring 309 is equal to the moving length of the aluminum profile, and the circumference of the fixed-length ring 309 can be designed by the operator according to the actual processing conditions; in the initial state, part of the rectangular frame 311 protrudes from the liquid storage cylinder 306, and part of the marking block 316 protrudes from the rectangular frame 311 (the outer diameter of the protruding marking block 316 and the fixed-length ring 309 are on the same horizontal plane). The rectangular frame 311 is vertically downward under its own weight. Therefore, when the aluminum profile moves and approaches the liquid storage cylinder 306, the marking block 316 in the rectangular frame 311 first contacts the aluminum profile and marks the initial position of one end of the aluminum profile.

[0030] Please see Figure 1 , Figure 2 , Figure 9 The feeding assembly includes a motor 402 fixedly connected to a fixed plate 401, a screw 403 rotatably connected between the two fixed plates 401, the output end of the motor 402 fixedly connected to one end of the screw 403, a screw sleeve 404 threadedly connected to the screw 403, a slide bar 405 fixedly connected to the screw sleeve 404, a sliding groove is provided on the worktable 1, the slide bar 405 is slidably connected to the sliding groove, and the clamping assembly is installed on the slide bar 405.

[0031] In this embodiment, after the aluminum profile is fixed by the clamping assembly, the motor 402 is started, and the motor 402 drives the screw 403 to rotate. The screw 403 drives the screw sleeve 404 to move along the axis of the screw 403 through the threaded engagement. The screw sleeve 404 drives the slide bar 405 to slide along the sliding groove on the worktable 1. The slide bar 405 drives the clamping assembly and the clamped aluminum profile to move synchronously towards the cutting mechanism 202 to realize automatic feeding. After one cut is completed, the motor 402 continues to rotate, and continues to transport the uncut aluminum profile forward until all cuts are completed. After the cut is completed, the motor 402 reverses and drives the clamping assembly back to the initial position to wait for the next feeding.

[0032] Please see Figures 9-11 The clamping assembly includes a clamping box 406 fixedly connected to a slide bar 405. Multiple evenly distributed locking blocks 411 are slidably connected to the surface of the clamping box 406. A connecting plate 407 is fixedly connected to the multiple locking blocks 411. Multiple evenly distributed springs 410 are fixedly connected between the connecting plate 407 and the clamping box 406. A push plate 408 is fixedly connected to the connecting plate 407 and slidably connected to the clamping box 406. A protective strip 409 is fixedly connected between the push plate 408 and the clamping box 406. Two symmetrically arranged guide rods 412 are fixedly connected to the side wall of the clamping box 406. A clamping plate 413 is slidably connected to the clamping plate 413. The clamping plate 413 is L-shaped. A spring 415 is sleeved on the guide rod 412. The two ends of the spring 415 are fixedly connected to the sides of the guide rod 412 and the clamping plate 413 that are close to each other. Multiple evenly distributed locking blocks 414 are fixedly connected to the clamping plate 413. The locking blocks 411 and the locking blocks 414 are interleaved. An anti-slip pad 417 is fixedly embedded in the clamping plate 413. A guide assembly is provided on the clamping plate 413. The guide assembly includes a triangular strip 416 fixedly connected to the clamping plate 413. The triangular strip 416 is a right triangle and the inclined surface of the triangular strip 416 faces the clamping box 406.

[0033] In this embodiment, the aluminum profile is first placed on the workbench 1. The operator then pulls the push plate 408 with one hand, causing the first clamping block 411 to retract into the clamping box 406 and compressing the second spring 410. The operator then uses their other hand to drag one end of the aluminum profile to the area between the clamping plate 413 and the backing plate 101, pressing down on that end. At this point, the aluminum profile contacts the triangular strip 416. Guided by the inclined plane, the aluminum profile pushes the clamping plate 413 outward along the guide rod 412, compressing the third spring 415. Once the aluminum profile is fully in the clamping position, the third spring 415 resets, pushing the clamping plate 413 inward to clamp the aluminum profile. The anti-slip pad 417 on the clamping plate 413 is in close contact with the surface of the aluminum profile, increasing friction and preventing slippage during conveying and cutting. At this point, the push plate is released. Under the elastic force of spring 410, plate 408 causes locking block 411 to move outward from the clamping box 406. Locking block 411 and locking block 414 on clamping plate 413 engage in a dog-tooth interlocking manner to form a one-way locking structure. This structure allows clamping plate 413 to move in the clamping direction but prevents clamping plate 413 from moving in the releasing direction, thereby ensuring that the aluminum profile will not be loosened due to vibration or external force during the cutting process. When it is necessary to release the aluminum profile, the operator pulls push plate 408. Push plate 408 drives connecting plate 407 and locking block 411 to move into clamping box 406, so that locking block 411 and locking block 414 disengage. At this time, the operator can take out the cut aluminum profile. The protective strip 409 is an elastic strip that extends and retracts according to the movement of push plate 408 to block the rectangular groove when push plate 408 moves.

[0034] In actual use, the aluminum profile cutting device first pushes the aluminum profile into the inlet side of the clamping box 406. Spring 3 415 drives the clamping plate 413 to press the aluminum profile. At this time, the clamping plate 413 cooperates with the backing plate 101 to form a clamp, preventing the aluminum profile from shifting laterally during movement. Then, the cooperation between the first clamping block 411 and the second clamping block 414 prevents the clamping plate 413 from shaking. Next, the electric push rod 303 is activated, driving the liquid storage cylinder 306 to descend, causing the anti-slip ring 310 on the fixed-length ring 309 to contact the upper surface of the aluminum profile and apply a preset pressure. The motor 402 is then activated, and the screw 403 drives the screw sleeve 404 and the clamping assembly to move, moving the aluminum profile forward. As the aluminum profile moves, the friction between the anti-slip ring 310 and the aluminum profile drives the fixed-length ring 309 to rotate. The fixed-length ring 309 drives the liquid storage cylinder 306 to rotate synchronously. For each rotation of the liquid storage cylinder 306, the first step block 318... After contacting step block 2 320 once, drive marking block 316 to extend from rectangular frame 311, leaving a cutting position mark on the aluminum profile surface. When the mark on the aluminum profile surface moves to the cutting position, the operator identifies the mark, controls motor 402 to stop, and simultaneously starts lifting mechanism 201. Lifting mechanism 201 drives cutting mechanism 202 to descend, and the circular saw blade in cutting mechanism 202 enters cutting hole 102 to cut aluminum profile. After cutting, lifting mechanism 201 drives cutting mechanism 202 to rise and reset, and motor 402 continues to rotate, continuing to transport the uncut aluminum profile forward. The above marking and cutting process is repeated. When the entire aluminum profile is cut, the operator pulls push plate 408 to disengage clamping block 1 411 from clamping block 2 414, removes the cut aluminum profile segment, and then motor 402 reverses, driving clamping assembly back to the initial position, ready for the next cutting operation.

[0035] The above embodiments are merely illustrative of several implementation methods of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
