Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, specifically to a grooving device for the production and processing of aluminum profiles for doors and windows. Background Technology

[0002] Aluminum profiles, with their lightweight, high strength, corrosion resistance, and excellent processing performance, have become a core material in modern door and window manufacturing. To improve the sealing performance of door and window products during installation and the reliability of the overall structure, high-precision and high-efficiency grooving processing of aluminum profiles is required during the production process. Grooving equipment for aluminum profiles plays a direct role in improving the modernization level of the industrial chain and meeting market demand for high-quality building materials, representing an important manifestation of intelligent manufacturing equipment in the building materials processing field. In the processing technology of aluminum profiles, milling is the core process for forming various grooves, holes, and contours, and is widely used in industries such as construction, machinery manufacturing, and rail transportation.

[0003] However, during the milling and grooving process, the intense friction between the milling cutter and the workpiece generates a large amount of cutting heat, causing a sharp rise in local temperature. High temperature easily accelerates the wear and dulling of the milling tool, resulting in a significant reduction in the service life of the milling cutter. At the same time, dulled tools are prone to causing abnormal plastic deformation and tearing of the material at the machining boundary, producing a large number of unavoidable burrs at the edge of the groove, which directly affects the assembly accuracy and appearance quality of the product, seriously reducing the product qualification rate. In addition, frequent tool changes not only increase production costs, but also disrupt the continuous production process, reducing the reliability and production efficiency of the intelligent manufacturing equipment industry. Summary of the Invention

[0004] The purpose of this invention is to provide a grooving device for the production and processing of aluminum profiles for doors and windows, so as to solve the problems mentioned in the above process.

[0007] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, the following features are provided: a movable seat is horizontally slidably connected to the frame; two fixed frames are fixedly installed on the frame; a lifting plate is vertically slidably provided between the two fixed frames; the isolation cover is fixed to the bottom of the lifting plate; and multiple clamping plates for fixing the workpiece are slidably provided on the movable seat.

[0008] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, a dry ice deburring machine is fixedly provided on the top of the lifting plate, and the outlet of the dry ice deburring machine is connected to the spray pipe.

[0009] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, wherein: a collection groove is provided in the return flow channel, the bottom surface of the collection groove is lower than the inner wall surface of the adjacent part of the return flow channel, and a guide slope for guiding the collection groove is fixed in the return flow channel.

[0010] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, the isolation cover is threadedly connected with a sealing plug, and the end of the sealing plug extends into the collection groove.

[0011] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, the air pipe is provided with a main channel and a backup channel, both of which are equipped with dryers, and a sealing plate for sealing the end of the main channel or the backup channel is slidably connected inside the air pipe.

[0012] In a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, a vertically arranged first spring is fixedly connected between the sealing plate and the air pipe, a clamping plate is fixedly installed on one side of the sealing plate, a sliding rod is slidably connected inside the air pipe, a trapezoidal block that cooperates with the clamping plate is fixedly installed at one end of the sliding rod, and a second spring is fixedly connected between the other end of the sliding rod and the air pipe.

[0013] In a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows described in this invention, a piston block is slidably connected inside the air pipe, a fixed pulley is rotatably connected inside the air pipe, and a pull rope that passes around the fixed pulley is fixedly connected between the end of the piston block and the end of the slide rod.

[0014] As a preferred embodiment of the grooving device for the production and processing of aluminum profiles for doors and windows according to the present invention, wherein: a pull rod for pulling the sealing plate to reset is fixedly installed at the bottom of the sealing plate, and the bottom of the pull rod slides through the bottom of the air pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention allows the workpiece to pass sequentially through a first chamber and a second chamber under an isolation cover. The aluminum profile passes through the first chamber where it is grooved by a milling cutter, and then enters the second chamber where it is deburred at low temperature by dry ice spraying. The grooving and deburring processes are completed sequentially. During the operation, the low-temperature gas in the second chamber is introduced into the first chamber to cool the milling cutter, thereby improving the tool's service life. This ensures both the product qualification rate and the continuity of the production process, thereby improving the reliability and processing efficiency of the intelligent manufacturing equipment industry.

[0016] 2. This invention uses a fan to draw low-temperature carbon dioxide generated by the sublimation of dry ice from the second chamber into the intake pipe, which then flows along the return flow channel. When it reaches the end of the return flow channel, it is sprayed out through the jet pipe toward the milling cutter's machining position. On the one hand, the low-temperature gas directly cools the milling cutter, preventing the tool material from softening and aggravating wear and dulling. On the other hand, it blows away the waste chips generated during milling, preventing the waste chip particles from scratching the tool and profile surface during subsequent processing. This improves the tool's service life, ensures the product's qualification rate, and enhances the reliability and processing efficiency of the intelligent manufacturing equipment industry.

[0017] 3. In the second chamber, the temperature continues to drop due to the continuous sublimation of dry ice. If the excessively cold gas is continuously sprayed onto the profile processing area, it can easily cause the aluminum profile to become brittle due to localized overcooling, leading to cracks during subsequent milling and affecting the final product quality. Therefore, this invention installs a contraction tube inside the air inlet pipe. When the gas flows through the contraction tube, based on the Venturi effect, the gas velocity increases and the static pressure decreases at its narrow point, thereby creating a negative pressure in that area. This negative pressure can automatically draw in ambient temperature air from outside through the air pipe, and after mixing and heating, the gas is then sprayed onto the processing area, thus avoiding the cold brittleness caused by excessively low gas temperature on the aluminum profile and effectively ensuring processing quality and product qualification rate.

[0018] 4. Both the main and backup air channels are equipped with dryers to dry the incoming ambient air. This prevents moisture in the ambient air from condensing into ice particles as it enters the low-temperature pipe. Ice particles move with the pipe and accumulate, which can easily block the gas flow. This ensures that during the grooving process of aluminum profiles, a stable cooling airflow is always directed at the milling cutter performing the processing task. This not only ensures the cooling effect on the milling cutter but also helps to improve the stability of the equipment operation.

[0019] 5. During normal operation, ambient temperature air enters the inlet pipe through the main channel of the air pipe and mixes with the low temperature gas. As the dryer in the main channel continues to absorb moisture, its ventilation resistance gradually increases, resulting in a relative decrease in the air pressure in the downstream pipe. When the air pressure drops to a set threshold, the internal air pressure will automatically pull the piston block to move. The pull rope that passes around the fixed pulley will drive the slide rod to move, causing the trapezoidal block to separate from the clamping plate. Then, under the action of the first spring, the sealing plate will move from the end of the backup channel to the end of the main channel, thereby automatically completing the switching between the main channel and the backup channel, ensuring the continuous supply of drying air to the equipment and the stable operation of the entire equipment.

[0020] 6. The bottom of the sealing plate is equipped with a pull rod for resetting it. When the resistance of the main channel dryer increases, causing the downstream air pressure to drop to the threshold, the sealing plate moves upward, completing the automatic switch from the main channel to the backup channel. The upward movement of the sealing plate simultaneously moves the pull rod upward, significantly reducing its length extending outside the air pipe. This provides operators with a clear and visible indication of the channel switching status. When the pull rod is observed to be in a shorter extended state, the operator knows that the equipment has switched to the backup channel and can immediately replace or regenerate the main channel dryer for maintenance. After maintenance is completed, manually pulling down the pull rod will move the sealing plate downward, switching back to the main channel. In this way, not only can the automatic switching and status indication of the channel be realized, but the maintenance and reset of the dryer can also be completed without stopping the equipment, greatly improving the overall operating efficiency and maintainability of the equipment.

[0021] 7. Even after drying, trace amounts of water vapor inevitably enter the air inlet pipe. When this water vapor comes into contact with low-temperature carbon dioxide gas, it condenses instantly and forms tiny ice particles. These ice particles enter the reversing flow channel with the airflow. The reversing flow channel is equipped with a guide slope at a set angle. Because the mass and inertia of the ice particles are much greater than those of gas molecules, when the airflow changes direction, the ice particles cannot turn with the gas in time due to inertia. They are thus guided and separated, eventually falling into the collection tank. At the same time, the mixed gas without ice particles after reversing continues to flow along the channel, completing the subsequent mixing and heating process. In this way, while achieving full mixing and heating of the gas, the effective separation and collection of ice particles are completed simultaneously, ensuring the long-term stable operation of the equipment.

[0035] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0036] Example 1, referring to Figure 1-12 According to the first embodiment of the present invention, a grooving device for the production and processing of aluminum profiles for doors and windows is provided. The grooving device for the production and processing of aluminum profiles for doors and windows includes a frame 1 and an isolation cover 4 slidably disposed above the frame 1. The isolation cover 4 is provided with a first chamber 41 and a second chamber 42. The first chamber 41 is provided with a milling cutter 7 for grooving, and the second chamber 42 is fixed with a spray pipe 61 for spraying dry ice. Sealing plates 43 are slidably connected to both sides of the bottom of the isolation cover 4. An exhaust pipe 44 is fixed through one side of the first chamber 41. A folding flow channel 47 is provided inside the first chamber 41. An air jet pipe 473 facing the machining position of the milling cutter 7 is fixed at the end of the folding flow channel 47. An air inlet pipe 46 communicating with the folding flow channel 47 is fixed inside the second chamber 42. A fan 461 is fixed inside the air inlet pipe 46. A constriction tube 462 is fixed inside the air intake pipe 46, and an air pipe 45 is provided on the outside of the isolation cover 4, which is connected to one side of the air intake pipe 46, and the connection position between the air pipe 45 and the air intake pipe 46 is located on the side of the constriction tube 462.

[0037] A hydraulic push rod 72 is fixedly installed on the isolation cover 4. A drive motor 71 is fixedly installed on the telescopic end of the hydraulic push rod 72. The spindle of the drive motor 71 is fixedly connected to the end of the milling cutter 7.

[0038] A movable seat 5 is horizontally slidably connected to the frame 1. Two fixed frames 2 are fixedly installed on the frame 1. A lifting plate 3 is vertically slidably provided between the two fixed frames 2. An isolation cover 4 is fixed to the bottom of the lifting plate 3. Multiple clamping plates 51 for fixing the workpiece are slidably provided on the movable seat 5.

[0039] A dry ice deburring machine 6 is fixedly installed on the top of the lifting plate 3, and the outlet of the dry ice deburring machine 6 is connected to the spray pipe 61.

[0040] Two electric push rods for driving the two sealing plates 43 to slide are fixedly installed on one side of the isolation cover 4. Multiple rollers that abut against the workpiece are rotatably connected to the opposite end faces of the two sealing plates 43.

[0041] The frame 1 is provided with a first screw threaded through the movable seat 5, and the fixed frame 2 is rotatably connected with a second screw threaded through the lifting plate 3. The two clamping plates 51 on the movable seat 5 are driven by electric push rods respectively.

[0042] During use, the aluminum profile is first placed on the movable seat 5, and the clamping plate 51 is fixed by the electric push rod corresponding to the clamping plate 51. The movable seat 5 is moved to the bottom of the isolation cover 4 by the rotation of the first screw, and the starting position of the slot is moved to the bottom of the milling cutter 7. Then, the lifting plate 3 is moved down by the rotation of the second screw, so that the two sealing plates 43 are located on both sides of the aluminum profile and above the clamping plate 51. Then, the sealing plate 43 is moved at the bottom of the isolation cover 4 by the electric push rod corresponding to the sealing plate 43, so that the multiple rollers on the two sealing plates 43 abut against both sides of the aluminum profile. Then, the drive motor 71 is started to drive the milling cutter 7 to rotate at high speed. Next, the hydraulic push rod 72 is activated to extend the telescopic end, causing the bottom of the milling cutter 7 to gradually extend into the aluminum profile. The extension amount of the hydraulic push rod 72 controls the depth of the milling groove. Then, the rotation of the first lead screw drives the moving seat 5 to move, causing the aluminum profile to move along the first chamber 41 towards the second chamber 42. The aluminum profile passes sequentially through the first chamber 41 and the second chamber 42 below the isolation cover 4. Simultaneously, the milling cutter 7 performs grooving on the moving aluminum profile. When the grooved part of the aluminum profile moves to below the second chamber 42, the dry ice deburring machine 6 sprays dry ice particles through the spray pipe 61 towards the grooving position. After the dry ice particles impact the workpiece at high speed, the low temperature generated by sublimation embrittles the burrs. The kinetic energy impact and the micro-explosive force generated by instantaneous sublimation peel the burrs off the workpiece surface without damaging the aluminum profile surface. This allows the equipment to sequentially complete the grooving and deburring processes. During the above operation, the second chamber 42 is filled with low-temperature carbon dioxide produced by the sublimation of dry ice. The fan 461 is activated, drawing the low-temperature carbon dioxide into the intake pipe 46. As the low-temperature carbon dioxide flows through the contraction pipe 462, due to the Venturi effect, the gas velocity increases and the static pressure decreases at the narrowest point, creating a negative pressure in that area. This negative pressure automatically draws in ambient air through the air pipe 45. The low-temperature carbon dioxide mixes with the ambient air and enters the return flow channel 47. During its flow along the return flow channel 47, thorough mixing and heat exchange occur, improving the efficiency of the return flow channel. The temperature of the mixed gas in chamber 47 is such that when it flows to the end of the return flow channel 47, it is sprayed out towards the milling cutter 7 through the jet pipe 473. This introduces the low-temperature gas in the second chamber 42 into the first chamber 41. On the one hand, the low-temperature gas directly cools the milling cutter 7, preventing the tool material from softening and aggravating wear and dulling. On the other hand, it blows away the waste chips generated during milling, preventing the waste chip particles from scratching the tool and profile surface during subsequent processing. This improves the tool's service life, ensures the product qualification rate, and enhances the reliability and processing efficiency of the intelligent manufacturing equipment industry.

[0043] Due to the continuous sublimation of dry ice particles in the second chamber 42, the temperature inside the chamber continues to decrease. If the gas at an excessively low temperature is continuously sprayed onto the profile processing area, it can easily cause the aluminum profile to become brittle due to localized overcooling, which can easily lead to cracks during subsequent milling and affect the final product quality. Therefore, through the Venturi effect, ambient temperature air is automatically introduced to mix with low-temperature carbon dioxide to increase the temperature of the gas ejected from the jet pipe 473, so that the temperature of the gas finally sprayed onto the processing area is within a safe range. This avoids the cold brittleness effect on the aluminum profile caused by excessively low gas temperature, effectively ensuring processing quality and product qualification rate.

[0044] In summary, by integrating the grooving and dry ice deburring processes into a continuous processing flow using the isolation cover 4, automated and efficient production is achieved. Furthermore, by utilizing the Venturi effect to automatically introduce room temperature air and mix it with low-temperature carbon dioxide generated by the sublimation of dry ice, intelligent gas temperature regulation is achieved. This not only avoids the risk of aluminum profile brittleness but also provides effective cooling for the milling cutter and chip removal, thus meeting the high reliability, high precision, and high stability requirements of intelligent manufacturing equipment.

[0045] The dry ice deburring machine 6 is existing technology and has been fully disclosed, so it will not be described in detail here.

[0046] Example 2, refer to Figure 8-12 This is the second embodiment of the present invention, which differs from the first embodiment in that: The air pipe 45 is provided with a main channel 451 and a backup channel 452. Both the main channel 451 and the backup channel 452 are provided with dryers 453. A sealing plate 455 for sealing the end of the main channel 451 or the backup channel 452 is slidably connected inside the air pipe 45.

[0047] A vertically arranged first spring 4552 is fixedly connected between the sealing plate 455 and the air pipe 45. A clamping plate 4551 is fixedly installed on one side of the sealing plate 455. A sliding rod 456 is slidably connected inside the air pipe 45. A trapezoidal block 4562 that cooperates with the clamping plate 4551 is fixedly installed at one end of the sliding rod 456. A second spring 4561 is fixedly connected between the other end of the sliding rod 456 and the air pipe 45.

[0048] A piston block 458 is slidably connected inside the air pipe 45, and a fixed pulley 457 is rotatably connected inside the air pipe 45. A pull rope 4571 that passes around the fixed pulley 457 is fixedly connected between the end of the piston block 458 and the end of the slide rod 456.

[0049] A pull rod 454 for resetting the sealing plate 455 is fixedly installed at the bottom of the sealing plate 455. The bottom of the pull rod 454 is sealed and slides through the bottom of the air pipe 45.

[0050] During normal operation, ambient temperature air enters the inlet pipe 46 through the main channel 451 of the air pipe 45 and mixes with the low-temperature gas. The dryer 453 is used to dry the incoming ambient temperature air to prevent the water vapor in the ambient temperature air from condensing into ice particles instantly upon entering the low-temperature pipe. This prevents the accumulation of ice particles from clogging the gas flow channel, thus ensuring that there is always a stable cooling airflow directed towards the milling cutter 7 that is performing the processing task during the grooving process of the aluminum profile. This not only ensures the cooling effect on the milling cutter 7, but also helps to improve the stability of the equipment operation.

[0051] As the dryer 453 in the main channel 451 continuously absorbs moisture, the air resistance of the dryer 453 in the main channel 451 gradually increases, resulting in a relative decrease in the air pressure in its downstream pipeline. When the air pressure drops to a set threshold, the internal air pressure will automatically pull the piston block 458 to move. When the piston block 458 moves, it pulls the pull rope 4571 that passes around the fixed pulley 457, causing the pull rope to drive the slide rod 456 away from the sealing plate 455. At the same time, the slide rod 456 compresses the second spring 4561, thereby causing the trapezoidal block 4562 to move away from the clamping plate 4551 until the trapezoidal block 4562 separates from the clamping plate 4551. At this time, under the action of the first spring 4552, the sealing plate 455 moves from the end of the backup channel 452 to the end of the main channel 451, thereby automatically completing the switching between the main channel 451 and the backup channel 452. The external ambient temperature air is dried by the dryer 453 in the backup channel 452, ensuring a continuous supply of drying air to the equipment and stable operation of the entire equipment.

[0052] The sealing plate 455 moves upward, causing the pull rod 454 to move upward, and at the same time, the main channel 451 and the backup channel 452 are automatically switched. The external ambient temperature air is dried by the dryer 453 in the backup channel 452, so that its downstream is restored to the normal pressure state. The elastic force of the second spring 4561 causes the end of the slide rod 456 to move to the pull rod 454 to achieve reset.

[0053] The upward movement of the sealing plate 455 causes the pull rod 454 to move upward, significantly reducing the length of the pull rod 454 extending beyond the air pipe 45. This provides the operator with a clear and visual indication of the channel switching status. When the operator observes that the pull rod 454 is in the shorter extended position, the operator knows that the equipment has switched to the backup channel 452. Subsequently, the operator can immediately replace or regenerate the dryer 453 in the main channel 451. After maintenance is completed, manually pulling down the pull rod 454 will cause the sealing plate 455 to move downward. The sealing plate 455 compresses the first spring 4552 and moves back to its original position. At the same time, the sealing plate 455 causes the locking plate 4551 to move downward. The movement causes the clamping plate 4551 to push the inclined surface of the trapezoidal block 4562, causing the slide rod 456 to compress the second spring 4561 until the clamping plate 4551 moves to below the trapezoidal block 4562. The elastic force of the second spring 4561 causes the slide rod 456 to move the trapezoidal block 4562 to above the clamping plate 4551, thereby limiting the sealing plate 455 and causing the air intake of the air pipe 45 to switch back to the main channel 451. In this way, not only can the automatic switching of the channel and the status indication be realized, but the dryer 453 can also be maintained and reset without stopping the equipment, which greatly improves the overall operating efficiency and maintainability of the equipment.

[0054] Dryer 453 is an adsorption dryer that uses an adsorbent (activated alumina) for drying, which is existing technology and will not be described in detail here.

[0055] The remaining structure is the same as that in Example 1.

[0056] Example 3, referring to Figure 5-8 This is the third embodiment of the present invention, which differs from the second embodiment in that: The folding flow channel 47 is provided with a collection groove 472. The bottom surface of the collection groove 472 is lower than the inner wall surface of the adjacent part of the folding flow channel 47. The guide slope 471 of the guide collection groove 472 is fixed in the folding flow channel 47.

[0057] A sealing plug 48 is threadedly connected to the isolation cover 4, and the end of the sealing plug 48 extends into the collection groove 472.

[0058] During operation, even after drying by the dryer 453, trace amounts of water vapor inevitably enter the air inlet pipe 46. When this water vapor comes into contact with the low-temperature carbon dioxide gas, it instantly condenses and forms tiny ice particles. These ice particles enter the reversing flow channel 47 along with the airflow. The reversing flow channel 47 is equipped with a guide slope 471 at a set angle. When the ice particles come into contact with the guide slope 471, because the mass and inertia of the ice particles are much greater than those of the gas molecules, the ice particles cannot turn with the gas in time when the airflow changes direction. As a result, they are guided by the guide slope 471 to the collection tank 472 for separation. The ice particles are eventually collected in the collection tank 472. At the same time, the mixed gas without ice particles after reversing continues to flow along the flow channel to complete the subsequent mixing and heating process. In this way, while achieving full mixing and heating of the gas, the effective separation and collection of ice particles are completed simultaneously, ensuring the long-term stable operation of the equipment.

[0059] After the processing is completed, the isolation cover 4 is raised to connect its bottom with the external environment, and the temperature in the second chamber 42 gradually returns to normal. Then, for maintenance and cleaning, the fan 461 can be started to introduce normal temperature air into the air inlet pipe 46, which circulates along the return flow channel 47. This warm airflow can accelerate the melting of the ice particles accumulated in the collection tank 472. After the ice particles have completely melted, the threaded sealing plug 48 can be unscrewed to drain the liquid water in the collection tank 472, completing the cleaning.

[0060] The remaining structure is the same as that in Example 2.
