Description

Technical Field

[0001] This invention relates to a shearing device for aluminum curtain walls, belonging to the field of cutting technology for aluminum profiles for antique buildings. Background Technology

[0002] Antique-style architecture refers to buildings specifically designed to imitate and replace ancient architecture, traditional religious temples and monasteries, traditional landscaping, historical buildings, cultural relics, and ancient village clusters, restoring the general appearance of historical features. Antique-style architecture can be broadly or narrowly defined. Broadly defined, it refers to the re-creation of ancient architectural forms in accordance with traditional cultural characteristics using modern or traditional building materials. Narrowly defined, it refers to the restoration of ancient buildings within a specific scope using traditional building materials, strictly speaking falling under the category of cultural relic restoration. This article only discusses the broad definition of antique-style architecture. The production and manufacturing process of antique-style architecture requires a large amount of aluminum profiles, necessitating the use of aluminum panel shearing equipment for curtain walls.

[0003] Chinese invention patent application CN201410472550.3 discloses a CNC hydraulic shearing machine. The variable-speed, material-separating, and follow-up material-supporting device is a device with variable speed, material sorting capabilities, and stable follow-up performance. This improves the working efficiency of the shearing machine, increases its automation level, saves users labor costs, and eliminates safety hazards caused by manual material sorting. The shearing machine's back gauge adjustment and lifting device features a simple assembly of the back gauge, a high overall strength structure, and is not easily deformed during use. During installation and debugging, the back gauge adjustment and lifting device uses a first adjustment component and a second adjustment component... After installation and debugging, the connection points of the entire component and the third adjustment component are stable and not easily moved during use, which improves the positioning accuracy of the shearing machine's back gauge. Moreover, when adjusting the accuracy, only the set screw needs to be adjusted, without other auxiliary tools, making the adjustment convenient and simple. This greatly improves work efficiency during actual production assembly and on-site debugging at the customer's location. The back gauge adjustment and lifting device increases the stroke of the shearing machine's back gauge through the flipping movement of the bracket. In addition, the shearing machine's back gauge achieves an avoidance function through this flipping, enabling a larger range of shearing for steel plates that exceed the stroke range of the back gauge.

[0004] However, although the CNC hydraulic shearing machine proposed in the aforementioned comparative documents has high strength, high positioning accuracy and high shearing range, its cutting mode is relatively simple during the cutting process. Especially for aluminum profiles for antique buildings, it is necessary to perform fine cutting and hollowing in multiple positions. In order to facilitate transportation, it is still difficult to preserve the whole piece of aluminum profile after cutting.

[0005] This application is made in view of the above. Summary of the Invention

[0006] The purpose of this invention is to provide a curtain wall aluminum panel shearing device to solve the above-mentioned problems. This device uses a switchable lifting platform with adjustable adsorption points to adsorb, fix, and move antique-style aluminum profiles. When the antique-style aluminum profile is located between the middle and upper processing tables, it is used for initial cutting. A rotary telescopic cutting machine performs the initial sawing of the aluminum profile using a circular saw, resulting in a curved edge at the cut edge. At this point, the antique-style aluminum profile can be moved between the middle and lower processing tables via movement control. The component-controlled dual-mode secondary sawing mechanism performs secondary processing at the sawing position, finely finishing the cut edges. The secondary processing uses a strip saw, resulting in neat cut edges. After cutting, holes can be drilled at the cutting position to reduce the connection strength at the aluminum profile cutting position. This ensures that when the aluminum profile is cut, the outer frame of the whole aluminum profile remains intact after cutting, is not easily deformed, and is convenient for transportation. The edge connection strength is low, and it can be easily disassembled as needed later. It has multiple processing modes and good processing and cutting effect.

[0007] This invention achieves the above objectives through the following technical solution: a curtain wall aluminum panel shearing device, comprising a bottom processing table, a middle processing table, an upper processing table, a connecting bracket, and a support frame. The bottom processing table, the middle processing table, and the upper processing table are connected sequentially by the connecting bracket, arranged from bottom to top. The support frame is welded to the bottom of the bottom processing table. The three-tiered platform provides different processing spaces for the antique-style aluminum profiles. When the antique-style aluminum profiles are located between the middle and upper processing tables, they are used for initial cutting, generating more sawdust. When the antique-style aluminum profiles are located between the middle and bottom processing tables, they are used for fine cutting, generating less sawdust. Separating the processing spaces facilitates the classification and processing of sawdust and allows for intelligent control of the suction intensity by an external vacuum cleaner.

[0008] It also includes a switchable adsorption point lifting platform, a motion control component, a rotary telescopic cutting machine, and a dual-mode secondary sawing mechanism. The switchable adsorption point lifting platform is fixedly installed in the bottom processing table for adsorption, fixation, and lifting control of aluminum profiles. The motion control component is installed at the bottom of both the middle processing table and the top processing table. The rotary telescopic cutting machine is installed on the motion control component located on the top processing table, and the dual-mode secondary sawing mechanism is installed on the motion control component located on the middle processing table.

[0009] In practical use, the antique-style aluminum profile is adsorbed and fixed using a lift platform with switchable adsorption points. Then, the aluminum profile is moved up and down under control. When the aluminum profile is between the middle and upper processing tables, it undergoes initial cutting. At this point, the intelligent control host drives the movement control component to activate, which in turn controls the movement of the rotary telescopic cutting machine. The rotary telescopic cutting machine performs the initial sawing and cutting of the aluminum profile using a circular saw. The cut edges have a curved edge. At this point, the antique-style aluminum profile can be placed between the middle and upper processing tables. When the bottom processing table is in contact with the material, the dual-mode secondary sawing mechanism is controlled by the motion control component to perform secondary processing at the sawing position, and the cutting edge is finely processed. The secondary processing uses a strip saw, and the cutting edge is neat. After the cutting is completed, holes can be drilled at the cutting position to reduce the connection strength at the cutting position of the aluminum profile. This ensures that when the aluminum profile is cut, the outer frame of the whole aluminum profile remains intact after the cutting is completed, which is not easy to deform and is convenient for transportation. The edge connection strength is low, and it can be easily disassembled as needed later. The processing mode is diverse and the processing and cutting effect is good.

[0010] Preferably, in order to enable the lifting control column to control the lifting and moving of the placement plate, the adsorption pump creates negative pressure by extracting air from the adsorption plate, thereby adsorbing and fixing the aluminum profile surface. The positions of the adsorption plate and the adsorption pump can be controlled by the movement of the first telescopic rod and the self-propelled seat, allowing the adsorption point to be adjusted according to the shape and processing requirements of the aluminum profile. This avoids the adsorption point coinciding with the cutting position of the aluminum profile, ensuring the cutting effect. The adjustable adsorption point lifting platform includes a lifting control column and a placement plate. The lifting control column is fixedly installed inside the bottom processing table, and the placement plate is installed on the top extension of the lifting control column. On the retractable end, the top of the placement plate is provided with a recessed groove. The adjustable adsorption point lifting platform also includes a first telescopic rod, a moving bar, and a self-propelled seat. The moving bar is connected to the telescopic end of the first telescopic rod. A strip-shaped groove is provided in the moving bar. The self-propelled seat is installed in the strip-shaped groove. The adjustable adsorption point lifting platform also includes an adsorption pump and an adsorption plate. The adsorption plate is disposed on the top suction end of the adsorption pump. The adsorption pump is fixed on the top of the self-propelled seat. The fixed end of the first telescopic rod is installed on the side wall of the recessed groove, and two first telescopic rods are symmetrically arranged on both sides of the recessed groove.

[0011] Preferably, in order to enable the drive motor to rotate the rotary screw, control the left and right moving seats to move left and right, carry the second telescopic rod and the front and rear moving seats to move left and right, and control the front and rear moving seats to move back and forth by extending and retracting the second telescopic rod, thereby flexibly adjusting the position of the adjustable suction point lifting platform or the rotary telescopic cutting machine, the movement control component includes a drive motor, a rotary screw, left and right moving seats and a sliding rod. The left and right moving seats on one side are movably mounted on the sliding rod. The rotary screw is connected to the output shaft of the drive motor. The left and right moving seats on the other side are threaded onto the rotary screw. The movement control component also includes a mounting base, a second telescopic rod and a front and rear moving seat. The mounting base is located at the end of the sliding rod. The second telescopic rod is fixedly located on the side wall of the left and right moving seats. The extension and retraction ends of the two second telescopic rods are respectively connected to the two sides of the front and rear moving seats. The front and rear moving seats serve as the direct mounting carrier for the adjustable suction point lifting platform or the rotary telescopic cutting machine.

[0012] Preferably, in order to enable the rotation of the rotating mounting plate to drive the third telescopic rod and the mounting frame to rotate, so that the sawing component in the mounting frame can flexibly perform secondary cutting processing on the aluminum profile, the bidirectional lead screw, driven by the motor, can drive the two sliding seats to separate or move closer, thereby flexibly cutting the aluminum profile. The dual-mode secondary sawing mechanism includes a rotating mounting plate, a third telescopic rod, and a mounting frame. The rotating mounting plate is connected to the output shaft of the servo motor built into the motion control component. The third telescopic rod is installed at the bottom of the rotating mounting plate. The mounting frame is fixedly set on the telescopic end of the third telescopic rod. The dual-mode secondary sawing mechanism also includes a bidirectional lead screw and sliding seats. A motor is embedded in one end of the inner wall of the mounting frame. One end of the bidirectional lead screw is connected to the output shaft of the motor. The other end of the bidirectional lead screw is connected to the side wall of the mounting frame through a rotating shaft. There are two sliding seats. The top of the sliding seats is slidably connected to the inner wall of the mounting frame. The two sliding seats are respectively installed on the threaded grooves with opposite directions at both ends of the bidirectional lead screw.

[0013] Preferably, in order to allow the direction of the double-sided saw blade to be adjusted by a motor, an electric cylinder can drive the double-sided saw blade to move up and down quickly. When the two saw teeth face each other, it is used to achieve a flat sawing of the aluminum profile. When the two separation cones are close together, they can drill holes at the cutting position of the aluminum profile to reduce the connection strength for rapid separation later. The dual-mode secondary sawing mechanism also includes an electric cylinder, a double-sided saw blade, and separation cones. The end of the electric cylinder is connected to the bottom motor output shaft of the sliding seat. The double-sided saw blade is fixedly installed on the telescopic end of the electric cylinder. The separation cones are welded to one side of the double-sided saw blade, and the other side of the double-sided saw blade is provided with saw teeth.

[0014] The beneficial effects of this invention are as follows: This invention uses a switchable lifting platform with adjustable adsorption points to adsorb, fix, lift, and move antique-style aluminum profiles. When the antique-style aluminum profiles are located between the middle and upper processing platforms, they are used for initial cutting. The aluminum profiles are initially sawn and cut using a rotary telescopic cutting machine and a circular saw. The cut edges have arc edges. At this point, when the antique-style aluminum profiles are located between the middle and lower processing platforms, a dual-mode secondary sawing mechanism is controlled by a movement control component to perform secondary processing at the sawing position. The cut edges are then finely processed using a strip saw, resulting in neat cut edges. After cutting, holes can be drilled at the cut position to reduce the connection strength at the cut position of the aluminum profile. This ensures that when the aluminum profile is cut into hollow pieces, its outer frame remains intact, is not easily deformed, and is easy to transport. The edge connection strength is low, allowing for easy disassembly as needed later. The processing modes are diverse, and the processing and cutting effect is good. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-7 As shown.

[0025] Example 1

[0026] A curtain wall aluminum panel shearing device includes a bottom processing table 1, a middle processing table 2, an upper processing table 3, a connecting bracket 4, and a support frame 5. The bottom processing table 1, the middle processing table 2, and the upper processing table 3 are connected sequentially by the connecting bracket 4 and arranged from bottom to top. The support frame 5 is welded to the bottom of the bottom processing table 1. The three-layer platform arrangement provides different processing spaces for antique building aluminum profiles. When the antique building aluminum profiles are located between the middle processing table 2 and the upper processing table 3, they are used for initial cutting, which produces more sawdust. When the antique building aluminum profiles are located between the middle processing table 2 and the bottom processing table 1, they are used for fine cutting, which produces less sawdust. Separating the processing spaces facilitates the classification and processing of sawdust and allows for intelligent control of the suction intensity by an external dust collection machine.

[0027] It also includes a switchable adsorption point lifting platform 6, a motion control component 7, a rotary telescopic cutting machine 8, and a dual-mode secondary sawing mechanism 9. The switchable adsorption point lifting platform 6 is fixedly installed in the bottom processing table 1 for adsorption and fixing of aluminum profiles and lifting control. The bottom of the middle processing table 2 and the bottom of the upper processing table 3 are both equipped with the motion control component 7. The rotary telescopic cutting machine 8 is installed on the motion control component 7 located on the upper processing table 3. The dual-mode secondary sawing mechanism 9 is installed on the motion control component 7 located on the middle processing table 2.

[0028] In practical use, the antique-style aluminum profile is adsorbed and fixed by the adjustable lifting platform 6, and then the aluminum profile is moved up and down. When the antique-style aluminum profile is between the middle processing platform 2 and the upper processing platform 3, it is used for initial cutting. At this time, the intelligent control host drives the movement control component 7 to start, and the movement control component 7 moves the rotary telescopic cutting machine 8. The rotary telescopic cutting machine 8 performs the initial sawing and cutting of the aluminum profile by circular sawing. The cut edge has a curved edge. At this time, the antique-style aluminum profile can be placed on the middle processing platform. When the aluminum profile is between the bottom processing table 1 and the bottom processing table 2, the dual-mode secondary sawing mechanism 9 is controlled by the motion control component 7 to perform secondary processing at the sawing position, and the cutting edge is finely processed. The secondary processing uses a strip saw, and the cutting edge is neat. After the cutting is completed, holes can be drilled at the cutting position to reduce the connection strength at the cutting position of the aluminum profile. This ensures that when the aluminum profile is cut, the outer frame of the whole aluminum profile remains intact after the cutting is completed, is not easily deformed, is convenient for transportation, and has low strength at the edge connection. It can be easily disassembled later as needed. The processing mode is diverse and the processing and cutting effect is good.

[0029] like Figure 3 and Figure 4As shown, the adjustable adsorption point lifting platform 6 includes a lifting control column 601 and a placement plate 602. The lifting control column 601 is fixedly installed inside the bottom processing table 1. The placement plate 602 is installed on the top telescopic end of the lifting control column 601. A recessed groove 603 is provided on the top of the placement plate 602. The adjustable adsorption point lifting platform 6 also includes a first telescopic rod 604, a moving bar 605, and a self-propelled seat 606. The moving bar 605 is connected to the telescopic end of the first telescopic rod 604. A strip-shaped groove is provided inside the moving bar 605. The self-propelled seat 606 is installed in the strip-shaped groove. The adjustable adsorption point lifting platform 6 also includes an adsorption pump 607 and an adsorption plate 608. The adsorption plate 608 is located on top of the adsorption pump 607. At the suction end, the adsorption pump 607 is fixed to the top of the self-propelled seat 606. The fixed end of the first telescopic rod 604 is installed on the side wall of the recessed groove 603, and two first telescopic rods 604 are symmetrically arranged on both sides of the recessed groove 603. The lifting control column 601 controls the lifting and moving of the placement plate 602. The adsorption pump 607 draws out the air in the adsorption plate 608 to form a negative pressure, thereby adsorbing and fixing the aluminum profile surface. The positions of the adsorption plate 608 and the adsorption pump 607 can be controlled by the movement of the first telescopic rod 604 and the self-propelled seat 606, so that the adsorption point can be adjusted according to the shape of the aluminum profile and the processing requirements of the aluminum profile, avoiding the adsorption point from coinciding with the cutting position of the aluminum profile and ensuring the cutting effect.

[0030] like Figure 5 As shown, the motion control assembly 7 includes a drive motor 701, a rotary screw 702, a left and right moving seat 705, and a sliding rod 704. The left and right moving seat 705 on one side is movably mounted on the sliding rod 704. The rotary screw 702 is connected to the output shaft of the drive motor 701. The left and right moving seat 705 on the other side is threaded onto the rotary screw 702. The motion control assembly 7 also includes a mounting base 703, a second telescopic rod 706, and a front and rear moving seat 707. The mounting base 703 is located at the end of the sliding rod 704, and the second telescopic rod 706 is fixedly mounted on the side wall of the left and right moving seat 705. The telescopic ends of the two second telescopic rods 706 are connected to the two sides of the front and rear moving seats 707 respectively. The front and rear moving seats 707 serve as the direct mounting carrier for the adsorption point switchable lifting platform 6 or the rotary telescopic cutting machine 8. The start of the drive motor 701 drives the rotary screw 702 to rotate, controlling the left and right moving seats 705 to move left and right, carrying the second telescopic rods 706 and the front and rear moving seats 707 to move left and right. The extension and retraction of the second telescopic rods 706 controls the front and rear moving seats 707 to move back and forth, thereby flexibly adjusting the position of the adsorption point switchable lifting platform 6 or the rotary telescopic cutting machine 8.

[0031] Example 2

[0032] A curtain wall aluminum panel shearing device includes a bottom processing table 1, a middle processing table 2, an upper processing table 3, a connecting bracket 4, and a support frame 5.

The support frame 5 is welded to the bottom of the bottom processing table 1. The three-tiered platform provides different processing spaces for the antique-style aluminum profiles. When the antique-style aluminum profiles are located between the middle processing table 2 and the upper processing table 3, they are used for initial cutting, producing more sawdust. When the antique-style aluminum profiles are located between the middle processing table 2 and the bottom processing table 1, they are used for fine cutting. The process produces less sawdust, separates the processing space, facilitates the classification and processing of sawdust, and allows for intelligent control of the suction intensity by external vacuum cleaners. It also includes a switchable suction point lifting platform 6, a movement control component 7, a rotary telescopic cutter 8, and a dual-mode secondary sawing mechanism 9. The switchable suction point lifting platform 6 is fixedly installed in the bottom processing platform 1 for the adsorption, fixation, and lifting control of aluminum profiles.

[0033] like Figure 6 As shown, the dual-mode secondary sawing mechanism 9 includes a rotating mounting plate 901, a third telescopic rod 902, and a mounting frame 903. The rotating mounting plate 901 is connected to the output shaft of a servo motor built into the motion control component 7. The third telescopic rod 902 is installed at the bottom of the rotating mounting plate 901. The mounting frame 903 is fixedly mounted on the telescopic end of the third telescopic rod 902. The dual-mode secondary sawing mechanism 9 also includes a bidirectional lead screw 904 and a sliding seat 905. A motor is embedded in one end of the inner wall of the mounting frame 903.

The top of the sliding seats 905 is slidably connected to the inner wall of the mounting frame 903. The two sliding seats 905 are respectively installed on the threaded grooves with opposite directions at both ends of the double-acting screw 904. The rotation of the rotating mounting plate 901 can drive the third telescopic rod 902 and the mounting frame 903 to rotate, so that the sawing component in the mounting frame 903 can flexibly perform secondary cutting processing on the aluminum profile. Under the drive of the motor, the double-acting screw 904 can drive the two sliding seats 905 to separate or move closer, thereby flexibly cutting the aluminum profile.

[0034] like Figure 7As shown, the dual-mode secondary sawing mechanism 9 also includes an electric cylinder 906, a double-sided saw blade 907, and a separating cone 909. The end of the electric cylinder 906 is connected to the bottom motor output shaft of the sliding seat 905. The double-sided saw blade 907 is fixedly installed on the telescopic end of the electric cylinder 906. The separating cone 909 is welded to one side of the double-sided saw blade 907. The other side of the double-sided saw blade 907 is provided with saw teeth 908. The direction of the double-sided saw blade 907 can be adjusted by the motor. The electric cylinder 906 can drive the double-sided saw blade 907 to move up and down quickly. When the two saw teeth 908 face each other, they are used to achieve a flat sawing of the aluminum profile. When the two separating cones 909 are close together, they can drill holes at the cutting position of the aluminum profile to reduce the connection strength for rapid separation later.
