Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of door and window profile cutting, and specifically to a cutting device for door and window profiles. Background Art
[0002] Door and window profiles are materials used to make door and window frames, including various types such as aluminum alloy, plastic steel, and broken bridge aluminum. These profiles have regular shapes and possess good strength, sealing performance, and decorative properties to meet various functional requirements of doors and windows in buildings.
[0003] Cutting devices for door and window profiles mainly include numerical control cutting devices and manual cutting devices. Numerical control cutting devices such as numerical control sawing machines can precisely control cutting dimensions, angles, and speeds through pre-programming, with high automation and cutting accuracy, and are suitable for large-scale and high-precision cutting operations of door and window profiles; manual cutting devices like manual saws are simple to operate and highly flexible, and are mainly used for simple cutting of door and window profiles during small-batch production or on-site installation.
[0004] However, the existing cutting devices for door and window profiles still have the following drawbacks during actual cutting and processing:
[0005] Firstly, there is a dilemma in metal dust treatment. When cutting door and window profiles, a large amount of metal dust will inevitably be generated. Currently, external vacuum cleaners are generally used to collect this dust by negative pressure suction. However, in actual operation, this method has obvious defects. During the cutting process, metal dust will fly around due to centrifugal force. Since the negative pressure suction range of the vacuum cleaner is relatively fixed and limited, it is often unable to handle the metal debris that splashes into the surrounding areas, resulting in a large amount of metal dust remaining in the working environment and being unable to be thoroughly cleaned. Neither the collection efficiency nor the final collection effect is satisfactory. In the long run, it will also have an adverse impact on the air quality of the workplace and the normal operation of the equipment.
[0006] Secondly, the noise hazard is serious. During the cutting operation, extremely strong noise will be emitted, and the intensity of this noise often exceeds the comfortable range that the human body can bear. Prolonged exposure to this high-decibel noise environment will cause physiological discomfort symptoms such as tinnitus and hearing loss in the staff. At the same time, it will also lead to psychological problems such as inattention and increased mental stress, greatly interfering with the working state of the staff, reducing work efficiency, and bringing great obstacles and troubles to the actual operation process of the entire cutting and processing. It may even lead to safety accidents due to worker operation errors caused by noise.
[0007] Thirdly, there is a hidden danger of high temperature for the cutting tool. As the cutting work continues, the cutting tool rubs violently against the door and window profiles for a long time, generating a large amount of heat, which causes the cutting tool to quickly heat up to a high temperature state. The high-temperature environment will change the metal microstructure of the cutting tool, resulting in a decrease in its hardness, poor toughness, and the cutting edge is more likely to be worn, deformed or chipped. This will not only greatly reduce the sharpness of the cutting tool, affecting the cutting accuracy and quality, but also significantly shorten the service life of the cutting tool, increasing the cost expenditure of the enterprise for frequent replacement of the cutting tool;
[0008] Fourthly, static electricity causes chain problems. During the cutting process, the existing cutting equipment lacks an effective static electricity elimination mechanism. The static electricity generated on the surface of the profile will adsorb the surrounding metal dust, making the metal dust tightly adhere to the surface of the profile. The negative pressure suction of an ordinary vacuum cleaner is difficult to overcome the static electricity adsorption force, and it cannot effectively clean the metal dust adsorbed by static electricity. This not only damages the originally smooth and beautiful surface of the profile, affecting the appearance quality and decorative effect of the product, but also may cause secondary pollution due to the shedding of dust during subsequent processing, assembly and use, bringing many inconveniences and potential quality hazards to the actual production and product application;
[0009] Fifthly, there is a lack of tool monitoring means. During the cutting process of the existing door and window profile cutting equipment, there is generally a lack of a tool monitoring device. When the tool gradually wears during long-term cutting work, it can only rely on the operator's experience and naked eyes to judge, or by stopping the machine and using professional measuring tools for detection. This manual monitoring method has many disadvantages. On the one hand, manual judgment is prone to errors and oversights, and it is difficult to detect the subtle wear of the tool in a timely manner. On the other hand, stopping the machine for detection will interrupt the production process, reduce production efficiency, and increase production costs. Moreover, in the absence of real-time monitoring, once the tool wears severely and is not detected in time, it may lead to quality problems such as inaccurate cutting dimensions and rough cutting surfaces of the profiles, and in severe cases, it may even damage the cutting equipment and door and window profiles, bringing unnecessary economic losses and production delays to the enterprise.

[0017] Preferably, an audible and visual alarm and a controller are arranged on the outer wall of the dust collection box. A sliding door is connected to the outer wall on the other side of the dust collection box by a pin shaft.
[0018] Preferably, a cylinder is arranged on the top of the monitoring box. A guide plate is arranged at the bottom of the inner cavity of the monitoring box.

[0019] Preferably, dust suction pipes II are arranged on the tops of multiple dust suction boxes. The ends of the dust suction pipe I and the dust suction pipes II are respectively connected to the outer wall of the monitoring box.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: During cutting, the electric push rod III can be started to work. It can push the cutting assembly carrying the protective part to slowly descend. During the descending process of the protective and sound-insulating box in the protective part, it will gradually approach and contact the door and window profiles. At this time, the cutting motor is immediately started and rotates at a high speed. Driven by the cutting motor, the cutting knife can perform cutting operations on the profiles. During the cutting process, as the cutting knife continuously penetrates into the profiles, the telescopic frame below the protective and sound-insulating box will slowly contract into the protective and sound-insulating box under the resistance of contacting the profile surface. In this way, the debris generated during the cutting process of the cutting knife on the profiles will be enclosed in the limited space between the protective and sound-insulating box and the support frame I. This unique design effectively blocks the possibly splashing metal debris, greatly reduces the situation of metal debris splashing everywhere, enables the metal debris to be concentrated in a relatively enclosed space, and thus brings great convenience to the subsequent dust suction work;
[0021] Since the cutting position is effectively enclosed by the protective and sound-insulating box and the support frame I, this not only plays a good role in controlling the metal debris, but also achieves remarkable results in noise control. During the cutting process, the intense friction between the cutting knife and the door and window profiles will generate a large amount of harsh noise. The enclosed structure composed of the protective and sound-insulating box and the support frame I can effectively block the noise propagation path and limit the noise within a smaller range, thereby greatly reducing the discomfort and harm brought by excessive noise to the staff, creating a relatively quiet and comfortable working environment for the staff, and improving the comfort and safety of the work.
[0022] Secondly, during the process of cutting door and window profiles, in order to effectively solve the problem of high temperature generated by the cutting tool due to long-term work, the device introduces the cooling vortex tube technology. Compressed gas from the outside is injected into multiple cooling vortex tubes I and II. Multiple cooling vortex tubes I and II can convert the air flow into cold air, and then these cold airs are respectively guided to multiple exhaust boxes, air outlet guiding housing I and multiple air outlet guiding housing II. Through these guiding components, the cold air can be guided to the bottom and top of the door and window profiles, directly acting on the contact area between the cutting tool and the door and window profiles. This all-round cold air blowing method can efficiently absorb the heat generated during the cutting process, effectively reduce the temperature of the cutting tool, thus significantly extending the service life of the tool, reducing the frequency of frequent tool replacement due to high temperature, lowering the production cost, and improving the continuity and stability of production;
[0023] Moreover, while blowing cold air to cool the tool, the device also integrates an electrostatic elimination function. When the cold air blowing towards the top of the door and window profile passes through the fixed cylinder, it will act on the electrostatic elimination rod II installed therein. The electrostatic elimination rod II releases a large number of positive and negative ions, enabling it to cooperate with the blowing of the cold air to neutralize the static charge on the surface of the profile, thereby effectively eliminating static electricity. Similarly, when the cold air blowing towards the bottom of the door and window profile passes through multiple electrostatic elimination rods I, static electricity will also be eliminated. This design of synchronously eliminating static electricity during the cooling process not only effectively solves the problem of static electricity on the surface of the profile during the cutting process, avoiding surface contamination and quality degradation of the profile caused by electrostatic adsorption of metal dust, but also the air flow can further clean the metal dust attached to the surface of the door and window profile during the blowing process, stripping the metal dust from the surface of the profile and moving it along with the air flow. Finally, under the suction of the dust suction pump I, the air flow carrying the metal dust is orderly transferred to the dust collection box for convenient unified cleaning and processing later. This integrated design further improves the cleanliness of the door and window profiles after cutting, making the surface of the profiles smoother and neater, significantly enhancing its appearance quality, and meeting the production and processing requirements of higher standards;
[0024] Moreover, during the process of collecting metal dust, the device is also equipped with a dust monitoring component. When the airflow carrying metal dust passes through the guide plate, the guide plate changes the direction and velocity of the airflow, enabling the airflow to pass through the monitoring area of the dust particle analysis sensor more evenly. The dust particle analysis sensor uses high-precision laser diffraction or image recognition technology to monitor the size and shape of the metal dust in real time and accurately, quickly analyzing key information such as the particle size and shape of the dust. Once it detects that the dust particles are too large or irregular in shape, according to the pre-set logical judgment, this may mean that the cutting tool is worn or the current cutting parameter settings are improper. At this time, the dust particle analysis sensor will quickly transmit the relevant data to the controller. After receiving the data, the controller immediately activates the audible and visual alarm to send an alarm signal, reminding the on-site staff to conduct inspections and handling in a timely manner. In this way, problems with the tool can be detected and measures can be taken at the initial stage, effectively reducing further cutting damage to the door and window profiles caused by improper tools or cutting parameters, and improving the product qualification rate and production quality.

A lead screw motor two 410 is arranged on the outer wall of the descending frame 400, and the output end of the lead screw motor two 410 is connected to a second lead screw;
[0039] It is convenient to drive the cutting assembly to cut the door and window profiles along the cutting line by using the lead screw motor 410;
[0040] A cutting assembly is sleeved on the outer wall of the circumferential surface of the second lead screw. The cutting assembly includes a second support frame 420. A protective part is fixedly connected to the outer wall of the second support frame 420 by screws. The protective part includes a protective sound-insulating box 430. A dust collection assembly is arranged at the bottom of the fixed seat 100. The dust collection assembly includes a dust collection box 500. A second dust suction pump 547 is arranged on the outer wall in front of the dust collection box 500. The output end of the second dust suction pump 547 is connected to a dust monitoring assembly.

[0041] Specifically, an electric push rod one 210 is arranged on the outer wall of the fixing plate 200. The output end of the electric push rod one 210 is connected to a clamping frame 220. An electric push rod two 230 is arranged on the top of the clamping frame 220.

[0042] Furthermore, a groove 331 is formed at the top of the first support frame 330. Springs 332 are arranged at the bottom of the inner cavities of a plurality of grooves 331. The ends of the plurality of springs 332 are connected to an exhaust box 333. Air delivery pipes 335 are arranged on the outer walls of the plurality of exhaust boxes 333. Electrostatic eliminator rods one 334 are arranged inside the plurality of exhaust boxes 333. Air delivery pipes 335 are also arranged on the outer walls of the plurality of exhaust boxes 333. The ends of the plurality of air delivery pipes 335 are connected to the refrigerating air outlet ends of a plurality of cooling eddy current pipes one 120.
[0043] In some embodiments: The principles of the plurality of cooling eddy current pipes one 120 and the plurality of cooling eddy current pipes two 441 are that the compressed gas is injected tangentially into the eddy current chamber after expanding and accelerating through the nozzle to form a free eddy current. Due to the interlayer friction, the energy of the central part of the air flow is transferred to the outer layer of the air flow. The kinetic energy of the central air flow decreases and the temperature drops. The kinetic energy of the outer layer of the air flow increases and part of it is converted into heat energy. Then, the central layer of the air flow with a reduced temperature is led out from one end through the central orifice plate to form a cold air flow, and the outer layer of the air flow with an increased temperature is led out from the other end through the control valve to form a hot air flow. Its structure mainly includes a nozzle for expanding and accelerating the gas, an eddy current chamber for forming a free eddy current, a cold end pipe for leading out the cold air flow, a hot end pipe for leading out the hot air flow, and a hot end regulating valve for regulating the flow rate of the hot air flow.

These ions will interact with the static charges in the cutting position environment under the traction of cold air, and opposite charges attract each other to neutralize the static charges on the object surface, achieving the purpose of eliminating static electricity. The principle is prior art, and its control console 600 is mainly used for controlling the device for use.
[0045] Furthermore, a dust suction base 336 is provided at the bottom of the support frame 330. A dust suction port 337 is opened at the top of the dust suction base 336, and a dust suction pipe 338 is further provided on the outer wall of the dust suction base 336, facilitating the collection of metal dust generated during the cutting of the bottom of the door and window profiles.

[0047] It should be noted that a dust suction box 450 is provided at the top of the protective and sound-insulating box 430. A fixed cylinder 440 is further provided on the outer wall of the protective and sound-insulating box 430. A cooling eddy tube 441 is provided on the outer wall of the fixed cylinder 440, and a static eliminator rod 442 is provided on the inner wall of the fixed cylinder 440. A through hole 340 matching the fixed cylinder 440 is further opened on the outer wall of the moving frame 320, and the through hole 340 facilitates the passing of the fixed cylinder 440, reducing the collision of its cooling eddy tube 441 and affecting its cutting stroke.
[0048] It should be noted that a telescopic frame 460 is slidably connected to the top of the protective and sound-insulating box 430. An air outlet guiding shell 470 and an air outlet guiding shell 480 are provided on the inner wall of the telescopic frame 460. Air inlet pipes 471 are provided on the outer walls of the air outlet guiding shell 470 and the air outlet guiding shell 480, and the ends of multiple air inlet pipes 471 are connected to the outer wall of the fixed cylinder 440, facilitating the transportation of cold air.
[0049] In some embodiments: A traction roller is further rotatably connected to the bottom of the telescopic frame 460, facilitating rolling traction during the cutting along the door and window profiles.
[0050] In addition, an audible and visual alarm 510 and a controller 520 are provided on the outer wall of the dust collection box 500. A sliding door 530 is connected to the other outer wall of the dust collection box 500 by a pin shaft.
[0051] In some embodiments: The acoustic-optic alarm 510 is a prior art. Its dust particle analysis sensor 545, controller 520, laser particle size analyzer 610, and acoustic-optic alarm 510 are electrically connected in series to facilitate timely monitoring and alarming.
[0052] In addition, a cylinder 541 is provided at the top of the monitoring box 540, a guide plate 542 is provided at the bottom of the inner cavity of the monitoring box 540, a connecting frame 543 is slidably connected inside the guide plate 542, rubber pads 544 are provided on the outer walls of both sides of the connecting frame 543, and multiple rubber pads 544 are in contact with the outer walls of both sides of the monitoring box 540. A dust particle analysis sensor 545 is also provided on the outer wall of the monitoring box 540, and a dust suction pump 546 is provided at the bottom of the monitoring box 540. The output end of the dust suction pump 546 is connected to a dust suction hose, and the end of the dust suction hose is connected to the outer wall of the dust collection box 500.
[0053] In some embodiments: The dust particle analysis sensor 545 mainly consists of a light source, a detection chamber, a photodetector, and a signal processing circuit. Its principle is based on light scattering. The light source emits light to irradiate the dust particles, causing them to scatter. Since the scattering characteristics of particles of different sizes are different, the scattered light intensity of large particles is stronger. The photodetector receives the scattered light and converts it into an electrical signal, which is processed by the signal processing circuit to obtain information such as particle size and concentration, and is compared with the preset standard data in the laser particle size analyzer 610. For metal dust, when the cutting tool wears, the size distribution of the generated metal dust particles is different from the normal situation, the particles become larger or the proportion of particles with specific abnormal sizes increases. By comparing the particle information detected by the dust particle analysis sensor 545 with the standard particle data under normal operating coefficients, the wear degree of the cutting tool can be judged, and then it can be reflected whether the operating coefficient deviates from the normal range, thereby providing a basis for equipment maintenance and process adjustment. The above all belong to the prior art.
[0054] In addition, dust suction pipes 451 are provided at the tops of multiple dust suction boxes 450, and the ends of the first dust suction pipe 338 and the second dust suction pipe 451 are respectively connected to the outer wall of the monitoring box 540.
[0055] In some embodiments, the cylinder 541 can be controlled by an external console to start, so that the connecting rod 543 carrying the rubber pad 544 is driven by the cylinder 541 to move downward to clean the monitoring port of the dust particle analysis sensor 545. The dust cleaned can be transferred to the inside of the dust collection box 500 through the first dust suction pump 546 for collection. Moreover, the guide plate 542 can further reduce the direct attachment of metal dust to the monitoring port of the dust particle analysis sensor 545, affecting its monitoring. The cylinder 541 can be controlled by the console 600 at regular intervals. The console 600 is internally provided with a PLC timer and is electrically connected to the cylinder 541. Thus, the dust particle analysis sensor 545 can be cleaned at regular intervals to achieve continuous monitoring. The device can use external conventional power supplies for power supply.
[0056] The working principle of the present invention: When cutting and processing door and window profiles, first, the door and window profiles are placed stably between two clamping components. These two clamping components are driven by a plurality of first electric push rods 210. Once receiving a control instruction, the first electric push rods 210 will drive the two clamping frames 220 connected thereto to move slowly until they closely fit from both sides of the door and window profiles, achieving stable lateral clamping. After completing the lateral clamping, to further ensure the stability of the door and window profiles during the cutting process, a plurality of second electric push rods 230 start to function. They will push the two clamping plates 240 to limit and fix the top of the door and window profiles. Thus, the door and window profiles are fixed in all directions on the cutting platform, effectively avoiding displacement and shaking that may occur during the cutting process, and greatly improving the cutting accuracy and safety. When the door and window profiles are firmly fixed, the cutting process is officially started. The first lead screw motor 310, as the power source for the horizontal movement of the cutting component, after receiving the start signal, the cutting component and the support component can reach the preset cutting position under the drive of the first lead screw motor 310. At this time, the third electric push rod 350 starts to work. It can push the cutting component carrying the protective part to slowly descend. During the descent, the protective sound insulation box 430 in the protective part will gradually approach and contact the door and window profiles. At this time, the cutting motor 421 is immediately started and rotates at a high speed. The cutting tool can perform cutting operations on the profiles under the drive of the cutting motor 421. During the cutting process, as the cutting tool 423 continuously penetrates into the profiles, the telescopic frame 460 below the protective sound insulation box 430 will slowly contract into the protective sound insulation box 430 under the resistance of contacting the profile surface. In this way, the chips generated during the cutting process of the cutting tool 423 on the profiles will be enclosed in the limited space between the protective sound insulation box 430 and the first support frame 330. This unique design effectively blocks the possible flying metal chips, greatly reducing the situation of metal chips flying everywhere, enabling the metal chips to be concentrated in a relatively enclosed space, and thus bringing great convenience to the subsequent dust suction work;
[0057] Since the cutting position is effectively enclosed by the protective sound-insulating box 430 and the first support frame 330, this not only plays a good role in controlling metal debris, but also achieves remarkable results in noise control. During the cutting process, the intense friction between the cutting tool 423 and the door and window profiles will generate a large amount of harsh noise. The enclosed structure composed of the protective sound-insulating box 430 and the first support frame 330 can effectively block the noise propagation path and limit the noise within a smaller range, thus greatly reducing the discomfort and harm caused by excessive noise to the staff, creating a relatively quiet and comfortable working environment for the staff, improving the comfort and safety of the work, and further being conducive to improving work efficiency and work quality;
[0058] Secondly, during the process of cutting the door and window profiles, in order to effectively solve the problem that the cutting tool generates high temperature due to long-term work, the device innovatively introduces the cooling vortex tube technology. Compressed gas from the outside is injected into the interiors of multiple first cooling vortex tubes 120 and second cooling vortex tubes 441. The multiple first cooling vortex tubes 120 and second cooling vortex tubes 441 can convert the air flow into cold air, and then this cold air is respectively guided to multiple exhaust boxes 333, the first air outlet guiding shell 470 and multiple second air outlet guiding shells 480. Through these guiding components, the cold air can be guided to the bottom and top of the door and window profiles and directly act on the contact area between the cutting tool 423 and the door and window profiles. This all-round cold air blowing method can efficiently absorb the heat generated during the cutting process, effectively reduce the temperature of the cutting tool, thus significantly extending the service life of the tool, reducing the frequency of frequent tool replacement due to high temperature, reducing production costs, and improving the continuity and stability of production;
[0059] Moreover, while cooling the cutting tool by blowing cold air, the device also integrates an electrostatic elimination function. When the cold air blown towards the top of the door and window profile passes through the inside of the fixed cylinder 440, it will act on the electrostatic eliminator rod two 442 installed therein. The electrostatic eliminator rod two 442 releases a large number of positive and negative ions, enabling it to cooperate with the blowing of the cold air to neutralize the static charges on the surface of the profile, thereby effectively eliminating static electricity. Similarly, when the cold air blown towards the bottom of the door and window profile passes through multiple electrostatic eliminator rods one 334, static electricity is also eliminated. This design of synchronously eliminating static electricity during the cooling process not only effectively solves the problem of static electricity on the surface of the profile during the cutting process, avoiding surface contamination and quality degradation of the profile caused by static electricity adsorption of metal dust, but also the air flow can further clean the metal dust attached to the surface of the door and window profile during the blowing process, stripping the metal dust from the surface of the profile and moving it along with the air flow. Finally, under the suction of the dust suction pump one 546, the air flow carrying the metal dust is orderly transferred to the inside of the dust collection box 500, facilitating unified cleaning and treatment in the later stage. This integrated design further improves the cleanliness of the door and window profile after cutting, making the surface of the profile smoother and neater, significantly enhancing its appearance quality, and meeting the production and processing requirements of higher standards;
[0060] Moreover, during the process of collecting metal dust by the device, a dust monitoring component is also equipped. When the air flow carrying metal dust passes through the guide plate, the guide plate changes the direction and flow rate of the air flow, enabling the air flow to pass through the monitoring area of the dust particle analysis sensor 454 more evenly. The dust particle analysis sensor 545 uses high-precision laser diffraction or image recognition technology to monitor the size and shape of the metal dust in real time and accurately, quickly analyzing key information such as the particle size and shape of the dust. Once it detects that the dust particles are too large or irregular in shape, according to the pre-set logical judgment, this may mean that the cutting tool is worn or the current cutting parameter settings are improper. At this time, the dust particle analysis sensor 545 will quickly transmit the relevant data to the controller 520. After receiving the data, the controller 520 immediately activates the sound and light alarm 510 to send an alarm signal, reminding the on-site staff to conduct inspections and take measures in a timely manner. In this way, problems with the cutting tool can be detected and measures can be taken at the initial stage, effectively reducing further cutting damage to the door and window profile caused by improper cutting tools or cutting parameters, and improving the product qualification rate and production quality.
