Description

Technical Field

[0001] This invention relates to the field of aluminum trapezoidal profile processing machine tool technology, specifically an automatic cutting machine tool for processing high-strength aluminum trapezoidal profiles. Background Technology

[0002] Aluminum ladder profiles are primarily made of high-strength aluminum alloy, with the core material being an aluminum-magnesium-silicon alloy or an aluminum-magnesium-zinc-copper alloy. They are processed into ladder structural components with specific cross-sectional shapes through extrusion molding. Aluminum ladder profile processing refers to the process of shaping raw aluminum alloy materials into profiles with specific cross-sectional shapes and dimensions that meet the structural requirements of aluminum ladders through processes such as extrusion, cutting, stamping, and surface treatment. The core purpose of this processing is to improve the mechanical properties of the aluminum ladder profiles.

[0003] The utility model disclosed in CN219402519U is an aluminum profile cutting device. It is composed of a vertical plate and a cutting table. A first electric telescopic rod is installed on the vertical plate. A motor with a cutting blade is installed on a fixed base to facilitate the cutting of corresponding aluminum profiles. Two support plates are set up and traction rollers are installed on the support plates to help pull the aluminum profile horizontally and facilitate the selection of the required length for cutting. The second electric telescopic rod cooperates with the moving clamping plate and the fixed clamping plate on the support plate to help to stably clamp both ends of the aluminum profile to be cut.

[0004] The utility model with announcement number CN218224865U discloses an aluminum profile cutting device for aluminum-plastic composite windows. Through a set of movable mechanisms, one side of one set of positioning plates is pushed outward, and the fastening spring on one side of the slider is squeezed. The aluminum profile is placed on the base and pushed to one side of the pushing block. Under the action of two sets of fastening springs, the two sets of positioning plates limit the two sides of the aluminum profile. When cutting, the cylinder works to push the sliding plate and the pushing block to move, thereby pushing the aluminum profile.

[0005] However, the automatic cutting device for aluminum profiles disclosed above still has the following problems in actual use: the aluminum profile is cut by the positioning mechanism of the cutting machine tool, but when this processing method is running, the aluminum chips that splash after cutting cannot be effectively collected. Some of the splashed aluminum chips enter the positioning groove inside the cutting machine tool, which increases the difficulty of cleaning and cannot be effectively collected, thus affecting the efficiency of subsequent positioning and processing operations.

[0006] Therefore, we propose an automatic cutting machine tool for processing high-strength aluminum trapezoidal profiles to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic cutting machine tool for processing high-strength aluminum trapezoidal profiles. This invention addresses the problem that existing cutting machine tools use positioning mechanisms to assist in cutting aluminum profiles, but in this type of processing, aluminum chips that splatter after cutting cannot be effectively collected. Some of the splattered aluminum chips enter the positioning groove inside the cutting machine tool, increasing the difficulty of cleaning and making effective collection impossible, thus affecting the efficiency of subsequent positioning and processing operations.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automatic cutting machine tool for processing high-strength aluminum trapezoidal profiles, comprising a cutting machine tool and a support column fixedly installed on the outside of the cutting machine tool; further comprising: The cutting machine tool is equipped with a cutting mechanism, which includes a cutting guide groove, and a saw blade assembly is slidably disposed inside the cutting guide groove; The top surface of the cutting machine tool is equipped with a positioning mechanism, which includes a positioning enclosure. Positioning brackets are slidably installed at the center of both the front and rear sides of the positioning enclosure, and the aluminum ladder profile is positioned by the positioning brackets. The top surface of the cutting machine tool is provided with a dust removal mechanism, which includes a dust removal bracket, and the dust removal bracket is distributed in a "Y" shape above the saw blade assembly.

[0009] Preferably, the top of the saw blade assembly included in the cutting mechanism is at a higher level than the top surface of the cutting machine tool, and cutting carriages are slidably arranged on both the front and rear sides inside the cutting machine tool, and transmission sliders are fixedly installed on the outer ends of the cutting carriages, and the transmission sliders are sleeved and slidably mounted on the front and rear sides outside the cutting machine tool.

[0010] Preferably, the cutting mechanism includes a guide screw, and the guide screw bearing rotates on the front and rear sides of the bottom surface of the cutting machine tool. The guide screw thread passes through the lower end of the transmission slider on the front and rear sides, and the left ends of the symmetrically arranged guide screws are connected to each other through a pulley assembly to drive the cutting carriage and the saw blade assembly to slide inside the cutting machine tool to realize the cutting operation of aluminum trapezoidal profile.

[0011] Preferably, the positioning mechanism includes a positioning enclosure fixedly installed on the outer side of the top surface of the cutting machine tool, and a bidirectional lead screw is rotatably provided at the center of the top surface of the positioning enclosure via a bearing. The positioning brackets symmetrically distributed inside the positioning enclosure are arranged in an inverted "L" shape, and the inner top surface of the positioning bracket is threaded to the outer wall of the bidirectional lead screw.

[0012] Preferably, the positioning mechanism includes a positioning liner, which is fixedly installed on the inner end of a symmetrically arranged positioning bracket. Lockable positioning sliders are provided at equal angles on the inner side of the symmetrically arranged positioning liner. The positioning sliders lock and position the outer end of the aluminum trapezoidal profile to prevent it from falling off after cutting.

[0013] Preferably, the dust removal mechanism includes a buffer horizontal groove with an inverted trapezoidal structure, and the buffer horizontal groove is equally spaced inside the top surface of the cutting machine tool. The interior of the equally spaced buffer horizontal groove is slidably connected to the bottom end of the pusher slider, and the top end of the equally spaced pusher slider is fixedly connected to the bottom surface of the dust removal bracket.

[0014] Preferably, the dust removal mechanism includes a dust removal sprayer, which is installed at equal intervals on the outer ends of the left and right sides of the dust removal bracket. The symmetrically arranged dust removal sprayers are distributed one-to-one with the buffer cross grooves. The buffer cross grooves contact the aluminum chips that splash after cutting and reduce their moving potential energy, thereby effectively collecting the aluminum chips.

[0015] Preferably, the dust removal mechanism includes an air supply sleeve, which is fixedly installed on the front and rear sides below the positioning enclosure in a symmetrical manner. Each of the symmetrically arranged air supply sleeves has a slidably arranged sealing piston inside, and each of the symmetrically arranged sealing pistons has an elastic telescopic rod fixedly arranged at its inner end. The inner end of each elastic telescopic rod is fixedly connected to the outer wall of the distributing slider.

[0016] Preferably, the dust removal mechanism includes a distributing slider fixedly installed on the top surface of the transmission slider, so that the elastic telescopic rod and the sealing piston supply air during the cutting movement of the saw blade assembly, and the air supply sleeves included in the dust removal mechanism are all provided with one-way exhaust pipes through their interiors at opposite ends, and the inner end of the one-way exhaust pipe is connected to the dust removal sprayer on the outside of the dust removal bracket.

[0017] Preferably, the dust removal mechanism includes a one-way air inlet valve, which is installed below the outer end of the air supply sleeve, so that each air supply sleeve conveys the exhaust gas into the dust removal sprayer by squeezing, so that the dust removal sprayer blows the aluminum chips inside the buffer cross groove to the collection groove on the side of the cutting machine tool for centralized recycling when it moves.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This automatic cutting machine tool for processing high-strength aluminum trapezoidal profiles positions the aluminum trapezoidal profiles through the positioning mechanism of the cutting machine tool. When the cutting mechanism moves to perform cutting operations, it drives the dust removal mechanism synchronously, so that the aluminum chips are pushed by the pusher slider at the bottom of the dust removal bracket and the dust removal sprayer on the outside, so as to improve the cutting efficiency by cleaning them up. The specific details are as follows: 1. By rotating the bidirectional screw above the positioning fence, the positioning bracket, which is slidably installed inside the positioning fence, is moved synchronously. The inner end of the positioning bracket is equipped with a positioning liner and a positioning slider. The inclined surface of the positioning slider contacts the outer end of the aluminum trapezoidal profile, and after pressing, the positioning slider is adjusted and locked to position the aluminum trapezoidal profile, preventing loosening and slippage due to cutting.

[0019] 2. The guide screw under the cutting machine rotates, driving the transmission slider and the cutting carriage to move synchronously. The saw blade assembly installed at the inner end of the cutting carriage moves along the direction of the cutting guide groove so as to cut the positioned aluminum trapezoidal profile.

[0020] Furthermore, the moving transmission slider drives the elastic telescopic rod and the sealing piston away from the air supply sleeve, so that the negative pressure air supply sleeve draws in external air through the one-way air inlet valve and stores it inside the air supply sleeve. After the sealing piston approaches the air supply sleeve, the internal air is transported out through the one-way exhaust pipe to achieve the effect of spraying dust removal and cleaning.

[0021] 3. When the saw blade assembly cuts aluminum trapezoidal profiles, aluminum chips splash outwards and come into contact with the cutting machine tool. They are blocked by buffer grooves that are opened at equal intervals, thereby reducing the potential energy of the splashing chips. The buffer grooves then collect the aluminum chips, preventing them from sliding outwards and facilitating subsequent collection.

[0022] Furthermore, the transmission slider dust removal bracket moves and slides in contact with the top surface of the cutting machine tool. At the same time, the pusher slider slides inside the buffer cross groove, pushing the aluminum chips stored inside the buffer cross groove so that the aluminum chips can be pushed out through the discharge cross groove to avoid residue affecting the cutting operation.

[0023] 4. When the sealed pistons inside the air supply sleeve approach each other, the air inside is transported outward through the one-way exhaust pipe. The dust removal sprayer then sprays the air into the corresponding buffer cross groove, blowing out the fine aluminum chips inside the buffer cross groove. The auxiliary pusher slider collects and discharges the aluminum chips, improving the cleaning effect on the cutting platform. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: To solve the problems existing in the cutting and processing of aluminum ladder profiles, this example discloses the following technical solution: an automatic cutting machine tool for processing high-strength aluminum ladder profiles, including a cutting machine tool 1. The top surface of the cutting machine tool 1 is provided with a positioning mechanism, and the positioning mechanism includes a positioning enclosure 5. Positioning brackets 6 are slidably arranged at the center positions of the front and rear sides of the positioning enclosure 5. The aluminum ladder profile is positioned by the positioning brackets 6. The positioning enclosure 5 included in the positioning mechanism is fixedly installed on the outer side of the top surface of the cutting machine tool 1. A bidirectional lead screw 12 is rotatably arranged at the center position of the top surface of the positioning enclosure 5 through a bearing. The positioning brackets 6 symmetrically distributed inside the positioning enclosure 5 are arranged in an inverted "L" shape. The inner top surface of the positioning bracket 6 is threaded to the outer wall of the bidirectional lead screw 12.

[0028] The positioning mechanism includes a positioning liner 13, which is fixedly installed on the inner end of the symmetrically arranged positioning bracket 6. The inner side of the symmetrically arranged positioning liner 13 is provided with lockable positioning sliders 14 at equal angles. The positioning sliders 14 lock and position the outer end of the aluminum trapezoidal profile to prevent it from falling off after cutting.

[0029] like Figures 6-7 As shown, the aluminum trapezoidal profile to be cut is placed above the cutting machine tool 1, with its end located inside the positioning brackets 6 on both sides of the positioning enclosure 5. Then, the bidirectional lead screw 12 above the positioning enclosure 5 is rotated by the servo motor. The positioning brackets 6, which are threadedly connected to the bidirectional lead screw 12, are limited by the positioning enclosure 5, so that the rotating bidirectional lead screw 12 drives the positioning brackets 6 on both sides to move synchronously, thereby adapting and adjusting according to the length of the aluminum trapezoidal profile.

[0030] Furthermore, after the positioning bracket 6 drives the positioning liner 13 and the positioning slider 14 at the inner end to approach the aluminum ladder bracket in sync, the positioning slider 14, which is set at equal angles, presses against the end of the aluminum ladder profile so that after contacting the inner inclined surface of the positioning slider 14, it slides outward to lock, thereby locking and positioning according to the specifications of the aluminum ladder profile to prevent it from falling off after subsequent fitting.

[0031] Example 2: In order to solve the problems existing in the cutting and processing of aluminum ladder profiles, this example discloses the following technical solution and a support column 2 fixedly installed on the outside of the cutting machine tool 1; the cutting machine tool 1 is provided with a cutting mechanism, and the cutting mechanism includes a cutting guide groove 3, and a saw blade assembly 4 is slidably arranged inside the cutting guide groove 3; the top horizontal height of the saw blade assembly 4 included in the cutting mechanism is higher than the top horizontal height of the cutting machine tool 1, and a cutting carriage 8 is slidably arranged on both the front and rear sides inside the cutting machine tool 1, and a transmission slider 9 is fixedly installed on the outer end of the cutting carriage 8, and the transmission slider 9 is sleeved and slidably mounted on the front and rear sides outside the cutting machine tool 1.

[0032] The cutting mechanism includes a guide screw 10, and the guide screw 10 is rotatably rotated on the front and rear sides of the bottom surface of the cutting machine tool 1. The guide screw 10 is threaded through the lower end of the transmission slider 9 on the front and rear sides. The left ends of the symmetrically arranged guide screws 10 are connected to each other through the pulley assembly 11, which is used to drive the cutting carriage 8 and the saw blade assembly 4 to slide inside the cutting machine tool 1 to realize the cutting operation of aluminum trapezoidal profile.

[0033] like Figures 1-3As shown, when cutting aluminum trapezoidal profiles, the drive motor installed on the right side of the cutting machine tool 1 operates, driving the guide screw 10 connected through the pulley assembly 11 to rotate, so that the guide screw 10 drives the threaded transmission slider 9 and the cutting carriage 8 to move inside the cutting machine tool 1. At the same time, the saw blade assembly 4 installed inside the cutting carriage 8 is driven to move along the direction of the cutting guide groove 3, so that the saw blade assembly 4 performs automatic cutting operation on the positioned aluminum trapezoidal profile during the movement.

[0034] Example 3: In order to solve the problems existing in the cutting and processing of aluminum ladder profiles, this example discloses the following technical solution: the dust removal mechanism includes an air supply sleeve 18, and the air supply sleeve 18 is fixedly installed on the front and rear sides below the positioning enclosure 5 in a symmetrical manner. The air supply sleeve 18 is slidably provided with a sealing piston 19 inside each of the symmetrically arranged air supply sleeves 18. The inner end of each of the symmetrically arranged sealing pistons 19 is fixedly provided with an elastic telescopic rod 20, and the inner end of each elastic telescopic rod 20 is fixedly connected to the outer wall of the distributing slider 23.

[0035] The dust removal mechanism includes a distributing slider 23 fixedly installed on the top surface of the transmission slider 9, so that the elastic telescopic rod 20 and the sealing piston 19 supply air during the cutting movement of the saw blade assembly 4. The air supply sleeves 18 included in the dust removal mechanism are all provided with one-way exhaust pipes 21 through their interiors at opposite ends, and the inner end of the one-way exhaust pipe 21 is connected to the dust removal sprayer 17 on the outside of the dust removal bracket 7. The dust removal mechanism includes a one-way air inlet valve 22, which is installed through the lower part of the outer end of the air supply sleeve 18, so that each air supply sleeve 18 conveys air into the dust removal sprayer 17 by squeezing and exhausting air.

[0036] like Figures 8-9 As shown, during the movement of the saw blade assembly 4 and the transmission slider 9, the elastic telescopic rod 20 and the sealing piston 19 distributed on the corresponding side are moved (the elastic force of the elastic telescopic rod 20 is greater than the pressure of the gas inside the air supply sleeve 18). After the sealing piston 19 on the left moves away from the air supply sleeve 18, it makes its interior a negative pressure state. Then, the one-way air inlet valve 22 set at the bottom of the air supply sleeve 18 draws in external air through the negative pressure state, so that it can be stored inside the air supply sleeve 18 to provide energy for subsequent cleaning operations.

[0037] Example 4: In order to solve the problems existing in the cutting and processing of aluminum ladder profiles, this example discloses the following technical solution: The top surface of the cutting machine tool 1 is provided with a dust removal mechanism, and the dust removal mechanism includes a dust removal bracket 7, which is distributed in a "Y" shape above the saw blade assembly 4; the dust removal mechanism includes a buffer transverse groove 15 with an inverted trapezoidal structure, and the buffer transverse groove 15 is equally spaced inside the top surface of the cutting machine tool 1, and the interior of the equally spaced buffer transverse groove 15 is slidably connected to the bottom end of the pusher slider 16, and the top end of the equally spaced pusher slider 16 is fixedly connected to the bottom surface of the dust removal bracket 7.

[0038] The dust removal mechanism includes a dust removal sprayer 17, which is installed at equal intervals on the outer ends of the left and right sides of the dust removal bracket 7. The symmetrically arranged dust removal sprayers 17 are distributed one-to-one with the buffer horizontal grooves 15. The buffer horizontal grooves 15 contact the aluminum chips that splash after cutting and reduce their moving potential energy, so as to effectively collect the aluminum chips. When the dust removal sprayer 17 moves, it blows the aluminum chips inside the buffer horizontal grooves 15 to the collection groove on the side of the cutting machine tool 1 for centralized recycling.

[0039] like Figures 4-5 As shown, during the cutting process of trapezoidal aluminum material, the saw blade assembly 4 produces aluminum chips that fly outwards and come into contact with the buffer grooves 15 on the top surface of the cutting machine tool 1. The buffer grooves 15, being trapezoidal in structure, slow down the movement of the aluminum chips after they come into contact with the chips, so that the aluminum chips can be collected by the buffer grooves 15, which are opened at equal intervals, preventing them from sliding outwards and facilitating subsequent collection.

[0040] Furthermore, during the movement of the saw blade assembly 4, the correspondingly distributed dust removal brackets 7 are moved by the transmission slider 9 at the outer end. The bottom surface of the dust removal bracket 7 slides against the top surface of the cutting machine tool 1. At the same time, the pusher slider 16 set on the bottom surface of the dust removal bracket 7 slides inside the buffer cross groove 15, thereby pushing the aluminum chips stored inside the buffer cross groove 15 so that after moving to the unloading cross groove opened on the side of the cutting machine tool 1, the aluminum chips are pushed out, avoiding excessive concentration and residue that affects normal cutting operations.

[0041] Simultaneously, the movement of the saw blade assembly 4 drives the transmission slider 9 to move the fixedly connected elastic telescopic rod 20. The sealing piston 19 at the end of the elastic telescopic rod 20 moves and squeezes into the air supply sleeve 18, so that the air stored inside the air supply sleeve 18 is squeezed and then transported outward through the one-way exhaust pipe 21. The dust removal sprayer 17, which is connected to the one-way exhaust pipe 21, sprays the air out and into the corresponding buffer cross groove 15, thereby assisting in blowing the fine aluminum chips inside the buffer cross groove 15, and assisting the pusher slider 16 in collecting and discharging the aluminum chips, thus improving the cleaning effect on the cutting platform 1.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
