Description

Technical Field

[0001] This invention relates to the field of glass frame processing equipment technology, specifically to an integrated device for cold bending of adjustable-angle glass frames. Background Technology

[0002] As a core component of glass products, the processing precision and bending quality of glass frames directly determine the assembly effect and service life of the glass products. Cold bending, because it eliminates the need for high-temperature heating of the profiles, effectively avoids oxidation and deformation, and fully preserves the original mechanical properties of the profiles, making it the mainstream process for glass frame processing. However, in existing technologies, the design of cold bending equipment for glass frames has some unresolved issues, such as the following: First, the angle adjustment is inconvenient and lacks precision, and it also lacks dual safety protection: most existing equipment uses fixed-angle molds. When processing frames with different bending angles, it is necessary to disassemble and replace the corresponding molds, which is cumbersome, time-consuming and labor-intensive. Moreover, positioning deviations are prone to occur during mold replacement, resulting in large fluctuations in bending angles, making it difficult to meet the requirements of high-precision processing. Even if there are some adjustable angle devices, their adjustment mechanisms are complex and mostly rely on single mechanical adjustment or simple electronic control. They lack a precise angle detection and feedback mechanism, and repeated trial bending and calibration are required after adjustment, which is inefficient. At the same time, there is no dedicated mechanical safety limit structure, which can easily lead to the scrapping of profiles or equipment damage due to accidental excessive rotation angle, increasing the cost of rework and scrapping.

[0003] Secondly, the processing flow is fragmented, with poor coordination and insufficient adaptability: In the existing processing, the leveling, clamping, bending and unloading of profiles require separate equipment, and the profiles need to be manually transferred between the equipment. This not only increases the labor intensity, but also easily causes scratches and deformation of the profiles during the transfer process, affecting product quality. At the same time, the collaborative operation of multiple equipment requires a large space, and the equipment purchase and maintenance costs are high, which does not meet the needs of intensive production.

[0004] Furthermore, the protection of the profiles is insufficient, resulting in a high damage rate: existing bending limit and clamping structures mostly adopt rigid contact and lack flexible buffer design, which can easily lead to pressure marks and scratches on the profile surface. This is especially true for ultra-thin and high-precision profiles, where the damage rate is even higher. Moreover, although some equipment attempts to set up buffer structures, the buffering effect is not good and cannot take into account the limit accuracy, which can easily cause profile deviation and further affect the bending quality.

[0005] In the existing technology, such as the fully automatic glass aluminum strip bending machine with publication number CN217453287U, it can only achieve angle adjustment of a single specification, but it lacks an integrated leveling and flexible protection structure, and does not have a dual angle control system function; another example is the integrated forming equipment for insulating glass with publication number CN216828568U, which achieves partial integration, but the angle adjustment accuracy is insufficient. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated device for cold bending of an adjustable-angle glass frame in order to solve the above-mentioned problems, as detailed below.

[0008] Preferably, the fixing mold assembly includes a fixing bracket and a fixing column. The fixing bracket is raised and fixed to the operating table body by the fixing column, and the fixing bracket is a horizontally arranged U-shaped bracket. Several clamping cylinders are fixedly arranged on the front end face of the fixing bracket. The output end of the clamping cylinder is inserted into the fixing bracket in a sliding fit manner and a clamping plate is fixed at the end. At the same time, the clamping plate is parallel to the rear part of the fixing bracket and is used to clamp one half of the profile to be bent.

[0009] Preferably, the bending die assembly includes a bending holder and a limiting cylinder. The bending holder is a horizontally arranged U-shaped holder and is located on the same horizontal direction as the fixed holder. The bending holder is fixedly connected to the bending drive assembly. Several limiting cylinders are fixedly arranged on the front end face of the bending holder. The output end of the limiting cylinder is inserted into the bending holder in a sliding fit manner, and a U-shaped wheel frame is fixed at the end. Several vertically arranged limiting rollers are rotatably installed between the upper and lower parts of the wheel frame through a wheel axle. At the same time, the limiting rollers are parallel to the rear part of the bending holder and are used to clamp and limit the other half of the profile to be bent.

[0010] Preferably, the bending drive assembly includes an L-shaped bracket, a bending motor, and a connecting seat.

A bearing seat two is coaxially rotatably connected to the bottom end of the support shaft, and the bearing seat two is fixed to the top surface of the operating platform body. A bending disc is coaxially fixed to the middle of the support shaft, and the outer side of the bending disc... The L-shaped connecting seat is fixedly connected to the rear of the bending die assembly, so as to drive the bending die assembly to rotate horizontally through the bending disc to perform profile bending action. The front of the bending disc is coaxially fixed with an arc-shaped top block, and the arc-shaped top block is located between the fixed die assembly and the bending die assembly, so as to limit and define the bending position. The bottom surface of the L-shaped bracket is fixedly equipped with an angle encoder, which is coaxial with the support shaft and linked with the bending motor, so as to detect the rotation angle of the support shaft and realize precise adjustment and control of the bending angle.

[0011] Preferably, the bending limiting assembly includes a planar bearing and a mounting base. The planar bearing is fixed to the top surface of the operating table body and coaxially disposed outside the bearing seat. The mounting base extending inward is fixedly mounted on both sides of the top of the planar bearing. The mounting bases on both sides are vertically inserted with clamping studs through threaded engagement at the positions where they extend out of the inner ring of the planar bearing. At the same time, a limiting post is vertically fixed on the top surface of the mounting base on one side to mechanically and safely limit the horizontal bending angle of the bending die assembly and prevent accidental excessive rotation angle.

[0012] Preferably, the profile leveling assembly includes a U-shaped bracket and a feeding motor. The U-shaped brackets are symmetrically arranged on the top front and rear of the operating table body, and the rear U-shaped bracket is fixed to the top surface of the operating table body. The front U-shaped bracket is connected to the operating table body through a spacing adjustment component. The feeding motor is vertically fixed to the top surface of each U-shaped bracket, and the output end of the bottom of the feeding motor passes through the U-shaped bracket in a sliding fit and is coaxially and vertically fixed to a rotating shaft. The bottom end of the rotating shaft is coaxially rotatably connected to a bearing seat, and the bearing seat is fixed to the bottom top surface of the U-shaped bracket. A leveling roller is coaxially fixed to the middle of each rotating shaft, and a buffer bushing is coaxially fixed to each leveling roller. At the same time, the front part of the buffer bushing at the rear position is laterally flush with the rear part of the fixed bracket.

[0013] Preferably, the spacing adjustment component includes an adjustment groove, an adjustment stud, and a guide post. The adjustment groove is longitudinally provided at the bottom of the U-shaped bracket at the front position. The adjustment stud and the guide post are vertically fixed on the top surface of the operating table body. The adjustment stud and the guide post both slide through the adjustment groove. The top of the adjustment stud extends out of the adjustment groove and is coaxially engaged with a locking nut.

[0014] Preferably, the back of the clamping plate is covered with a flexible buffer pad, and the flexible buffer pad is made of rubber; the limiting roller is a wear-resistant rubber roller; the bottom and top of the clamping stud are respectively fixed with an elastic pressure block and a handle; the outer periphery of the bottom surface of the flattening roller at the rear position is coaxially fixed with an anti-fall flange; and the adjusting groove is a waist-shaped groove arranged along the longitudinal direction.

[0015] Preferably, the discharge push assembly includes a mating hole and a push cylinder. The bottom surfaces of both the fixed bracket and the bending bracket are vertically provided with the mating hole. The bottom surfaces of both the fixed bracket and the bending bracket are vertically fixed with the push cylinder. The top of the push cylinder is provided with a push rod that can reciprocate vertically, and the push rod is coaxially and slidably engaged with the mating hole.

[0016] Preferably, the control component includes a microcomputer controller and a touch screen. The microcomputer controller is located on the top surface of the control panel, and the touch screen is disposed on the top surface of the microcomputer controller. Additionally, the microcomputer controller is also provided with a power switch and an emergency stop button on the side of the touch screen.

[0017] In practical applications, the aforementioned adjustable-angle glass frame cold bending integrated device, due to the addition of an angle encoder to the bending drive assembly and its electrical connection with the control assembly, can detect the rotation angle of the support shaft in real time and provide feedback signals. This allows for automatic control of the bending motor's start and stop via the angle encoder and the control assembly, achieving precise adjustment and automatic control of the bending angle without the need for mold disassembly or replacement. Furthermore, the angle encoder's high detection accuracy ensures precise control of the bending angle. Additionally, a bending limiting assembly is provided externally to the bending drive assembly, where the limiting post of the bending limiting assembly abuts against the bending point during the bending process. The external mechanical stop of the clamping seat provides a mechanical safety limit on the bending angle of the bending die assembly, forming a dual angle protection system with the angle encoder. This ensures that even if the angle encoder malfunctions or the control component malfunctions, the bending limit component can still effectively prevent the bending die assembly from continuing to rotate, preventing excessive rotation angles that could lead to profile scrapping. This improves operational safety and helps reduce scrapping costs. Furthermore, by integrating the profile leveling assembly, the fixing die assembly, the bending die assembly, the bending drive assembly, the bending limit component, and the discharge push assembly onto the operating table body, the entire process from profile leveling, segmented clamping, bending to discharge is realized. The integrated operation throughout the entire process reduces manual intervention. Simultaneously, the control component is electrically connected to the profile leveling component, the fixing mold component, the bending mold component, the bending drive component, and the discharge push component, achieving automated control. Operators only need to set parameters using the touch screen to complete the profile processing, eliminating the need for real-time manual monitoring of the bending angle. This helps improve processing efficiency and reduce labor intensity. Furthermore, because the profile leveling component includes a polished buffer bushing, the profile is rolled through this bushing, achieving surface flatness before bending and avoiding bending deviations caused by the profile's own bending. Meanwhile, the fixing mold component... The clamping plate is also equipped with a flexible buffer pad, which can cushion and protect the profile during clamping. Furthermore, the limiting rollers of the bending die assembly are made of wear-resistant rubber and can rotate around the axle, thus cushioning and protecting the profile surface during bending and guiding its movement, achieving all-around flexible protection. Additionally, the spacing adjustment component in the profile leveling assembly allows for adjustment of the distance between the two leveling rollers, accommodating profiles of different thicknesses. Simultaneously, the limiting post in the bending limiting assembly can be adjusted in position by rotating the plane bearing, thus adapting to different bending angles of the bending die assembly.Furthermore, the clamping cylinders and limiting cylinders of both the fixed mold assembly and the bending mold assembly can adjust the clamping force, thus adapting to the processing needs of glass frames with different specifications and bending angles. This eliminates the need for separate equipment for different profile specifications, improving the equipment's applicability. Additionally, the control assembly is equipped with an emergency stop button, allowing for rapid shutdown in emergencies and preventing safety accidents caused by equipment malfunctions or operational errors. The dual system of "electronic precision angle control + mechanical safety limit" not only improves angle control accuracy but also avoids potential malfunctions associated with a single angle control method, contributing to improved operational safety and equipment stability, and reducing equipment maintenance frequency and costs.

[0018] The beneficial effects are as follows: 1. This invention adds an angle encoder to the bending drive assembly, and the angle encoder is electrically connected to the control assembly. It can detect the rotation angle of the support shaft in real time and feed back the signal. Thus, the bending motor can be automatically controlled to start and stop with the help of the angle encoder and the control assembly, realizing precise adjustment and automatic control of the bending angle without disassembling and replacing the mold. At the same time, the angle encoder has high detection accuracy, which can ensure precise control of the bending angle. Moreover, a bending limit assembly is also set on the outside of the bending drive assembly. In the bending process, the limit post of the bending limit assembly abuts against the outside of the bending card seat to mechanically stop the bending angle of the bending mold assembly. This achieves a dual angle protection system with the angle encoder. It ensures that when the angle encoder fails or the control assembly is abnormal, the bending limit assembly can still effectively prevent the bending mold assembly from continuing to rotate, preventing the profile from being scrapped due to excessive rotation angle. This improves operational safety and helps to reduce scrap costs. 2. The profile leveling component, fixing mold component, bending mold component, bending drive component, bending limit component, and discharge push component are integrated on the operating table body, realizing the whole process of profile leveling, segmented clamping, bending to discharge in an integrated manner, reducing the number of manual intervention links. At the same time, the control component is electrically connected to the profile leveling component, fixing mold component, bending mold component, bending drive component, and discharge push component, realizing automated control. Operators only need to set parameters with the touch screen to complete the processing of profiles, without the need for manual real-time monitoring of bending angle, which helps to improve processing efficiency and reduce labor intensity. 3. The profile leveling assembly is equipped with a polished buffer bushing. By rolling the buffer bushing, the profile can be leveled before bending, avoiding bending deviations caused by the profile's own bending. At the same time, the clamping plate of the fixed mold assembly is also equipped with a flexible buffer pad, which can buffer and protect the profile during clamping. Furthermore, the limiting roller of the bending mold assembly is made of wear-resistant rubber and can rotate around the wheel axle, which can buffer and protect the profile surface during bending and guide the profile's movement during bending, achieving all-round flexible protection for the profile. 4. A spacing adjustment component is set in the profile leveling assembly, which can adjust the spacing between the two leveling rollers to adapt to profiles of different thicknesses. At the same time, the limiting post in the bending limiting assembly can be adjusted by rotating the plane bearing to adjust the limiting position, so as to adapt to different bending angles of the bending die assembly. Moreover, the clamping cylinders and limiting cylinders of the fixed die assembly and the bending die assembly can adjust the clamping force, thus adapting to the processing needs of glass frames of different specifications and bending angles. There is no need to configure separate equipment for different specifications of profiles, which improves the applicability of the equipment. 5. The control components are equipped with an emergency stop button, which can quickly stop the machine in an emergency to avoid safety accidents caused by equipment failure or operational errors. At the same time, the dual system of "electronic precision angle control + mechanical safety limit" not only improves the angle control accuracy, but also avoids the potential faults that may occur with a single angle control method. This helps to improve operational safety and equipment stability, and reduce equipment maintenance frequency and costs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] See Figures 1-12 As shown, the present invention provides an integrated cold bending device for adjustable-angle glass frames, including an operating platform body 4. A frame 401 for raising and supporting is fixedly installed at the bottom of the operating platform body 4. A fixing mold assembly 2 is fixedly arranged in the middle of the operating platform body 4 to clamp one half of the profile. Specifically, the fixing mold assembly 2 includes a fixing bracket 203 and a fixing post 204. The fixing bracket 203 is raised and fixed on the operating platform body 4 by the fixing post 204, and the fixing bracket 203 is a horizontally arranged U-shaped bracket. The front end of the fixed card holder 203 is fixedly equipped with several clamping cylinders 201. The output end of the clamping cylinder 201 is inserted into the fixed card holder 203 in a sliding fit and the end is fixed with a clamping plate 202. At the same time, the clamping plate 202 is parallel to the rear part of the fixed card holder 203 to clamp one half of the profile to be bent. Preferably, multiple clamping cylinders 201 are synchronized. The purpose of this arrangement is to facilitate the clamping of one half of the profile between the clamping plate 202 and the fixed card holder 203 by pushing the clamping plate 202 through the clamping cylinder 201.

[0024] See Figures 1-12As shown, a profile leveling component 3 for surface leveling of the profile to be bent is provided on one side of the fixed mold assembly 2. The profile leveling component 3 is located on the top surface of the operating table body 4. The profile leveling component 3 is used to perform surface leveling of the profile before bending. Specifically, the profile leveling component 3 includes a U-shaped bracket 302 and a feeding motor 301. U-shaped brackets 302 are symmetrically arranged on the front and rear of the top surface of the operating table body 4. The rear U-shaped brackets 302 are fixed to the top surface of the operating table body 4, and the front U-shaped brackets 302 are connected to the operating table body 4 through a spacing adjustment component 308. The feeding motor 301 is vertically fixed on the top surface of each U-shaped bracket 302, and the output end of the bottom of the feeding motor 301 passes through the U-shaped bracket in a sliding fit manner. The U-shaped bracket 302 is coaxially and vertically fixed with a rotating shaft 303. The bottom end of the rotating shaft 303 is coaxially rotatably connected to a bearing seat 307, and the bearing seat 307 is fixed to the bottom top surface of the U-shaped bracket 302. The middle part of the rotating shaft 303 is coaxially fixed with a leveling roller 304, and the leveling roller 304 is coaxially fixed with a buffer bushing 305. At the same time, the front part of the buffer bushing 305 at the rear position is horizontally flush with the rear part of the fixed card seat 203. The reason for this arrangement is that by using the rolling of the buffer bushing 305 to pass through the profile, the surface of the profile can be leveled before bending, avoiding bending deviation caused by the bending of the profile itself. It should be noted that the two feeding motors 301 rotate in opposite directions to achieve leveling and forward conveying of the profile.

[0025] See Figures 1-10 As shown, the spacing adjustment component 308 includes an adjustment groove 3081, an adjustment stud 3084, and a guide post 3082. The bottom of the U-shaped bracket 302 at the front position has an adjustment groove 3081 longitudinally. The top surface of the operating table body 4 is vertically fixed with the adjustment stud 3084 and the guide post 3082, and the adjustment stud 3084 and the guide post 3082 both slide through the adjustment groove 3081. The top of the adjustment stud 3084 extends out of the adjustment groove 3081 and is coaxially engaged with a locking nut 3083. The purpose of this arrangement is to adjust the spacing between the two flattening rollers 304 by longitudinally sliding the adjustment groove 3081 and tightening the locking nut 3083, which is suitable for use with profiles of different thicknesses.

[0026] See Figures 1-12As shown, on the other side of the fixed mold assembly 2, a bending mold assembly 1 is provided for clamping and limiting the other half of the profile. Specifically, the bending mold assembly 1 includes a bending holder 101 and a limiting cylinder 102. The bending holder 101 is a horizontally arranged U-shaped holder and is located on the same horizontal direction as the fixed holder 203. The bending holder 101 is fixedly connected to the bending drive assembly 6. Several limiting cylinders 102 are fixedly arranged on the front end face of the bending holder 101. The output end of the limiting cylinder 102 is inserted into the bending holder 101 in a sliding fit manner, and the end... A U-shaped wheel frame 103 is fixed, and multiple vertically arranged limiting rollers 105 are rotatably mounted between the upper and lower parts of the wheel frame 103 via a wheel axle 104. At the same time, the limiting rollers 105 are parallel to the rear part of the bending clamp 101 and are used to clamp and limit the other half of the profile to be bent. The purpose of this arrangement is that the limiting rollers 105 can be moved by the limiting cylinder 102 to clamp and limit the other half of the profile to be bent. Moreover, since the limiting rollers 105 are rotatable, they can guide and adapt to the movement of the profile during the bending process, specifically through a pull-out motion.

[0027] See Figures 1-12 As shown, both the fixed mold assembly 2 and the bending mold assembly 1 are fixedly equipped with a discharge push assembly 8 at their bottom. Specifically, the discharge push assembly 8 includes a mating hole 802 and a push cylinder 801. The bottom surfaces of the fixed card seat 203 and the bending card seat 101 are both vertically provided with mating holes 802. The bottom surfaces of the fixed card seat 203 and the bending card seat 101 are both vertically fixed with push cylinders 801. The top of the push cylinder 801 is provided with a push rod 803 that can reciprocate vertically. The push rod 803 is coaxially and slidably engaged with the mating hole 802. With this configuration, after bending is completed and the clamping cylinder 201 and the limiting cylinder 102 are both released from the profile, the push cylinder 801 drives the push rod 803 to rise, which can push the profile higher than the fixed card seat 203 and the bending card seat 101, thereby facilitating the worker to remove the bent profile from the operating table body 4.

[0028] See Figures 1-10As shown, a bending drive assembly 6 with adjustable bending angle is fixedly arranged at the rear position between the fixed mold assembly 2 and the bending mold assembly 1 on the operating table body 4. The bending drive assembly 6 is fixedly connected to the bending mold assembly 1 and is used to drive the bending mold assembly 1 to rotate horizontally to bend the profile. Specifically, the bending drive assembly 6 includes an L-shaped bracket 607, a bending motor 601, and a connecting seat 605. An inverted L-shaped bracket 607 is fixed at the rear position of the operating table body 4 behind the fixed mold assembly 2. A bending motor 601 is vertically fixed to the top surface of the frame 607. The output end of the bending motor 601 passes through the L-shaped bracket 607 in a sliding fit, and a support shaft 602 is coaxially fixed to its bottom end. A bearing seat 606 is coaxially rotatably connected to the bottom end of the support shaft 602, and the bearing seat 606 is fixed to the top surface of the operating table body 4. A bending disc 604 is coaxially fixed to the middle of the support shaft 602, and the outer side of the bending disc 604 is fixedly connected to the rear of the bending die assembly 1 through an L-shaped connecting seat 605, so as to drive the bending disc 604. The bending die assembly 1 rotates horizontally to perform profile bending. An arc-shaped top block 603 is coaxially fixed to the front of the bending disc 604, and is located between the fixed die assembly 2 and the bending die assembly 1. This arc-shaped top block 603 is used to limit and define the bending position. An angle encoder 608 is fixedly mounted on the bottom surface of the L-shaped bracket 607. The angle encoder 608 is coaxial with the support shaft 602 and linked to the bending motor 601 to detect the rotation angle of the support shaft 602, thereby achieving precise adjustment and control of the bending angle. With this setup, the bending process begins... The motor 601 drives the support shaft 602 and the bending disc 604 to rotate, which enables the bending holder 101 to rotate and perform the bending operation on the profile. During this process, the bending of the profile is guided by the surface of the profile contacting the outer surface of the arc-shaped top block 603. At the same time, the rotation angle of the support shaft 602 can be detected by the angle encoder 608. After feedback control of the bending motor 601, the bending angle can be precisely adjusted and controlled. The preferred bending angle adjustment range is 0° to 180°, and the suitable profile thickness is 1 to 10 mm.

[0029] See Figures 1-12As shown, a bending limiting component 5 is also provided on the outside of the bending drive component 6, and the bending limiting component 5 is fixed on the top surface of the operating table body 4. It is used to mechanically and safely limit the bending angle of the bending die component 1. Specifically, the bending limiting component 5 includes a plane bearing 502 and a mounting base 505. The plane bearing 502 is fixed on the top surface of the operating table body 4 and is coaxially arranged outside the bearing seat 606. Mounting bases 505 extending inward are fixedly placed on both sides of the top of the plane bearing 502. At the position where the mounting bases 505 on both sides extend outward from the inner ring of the plane bearing 502, a clamping stud 501 is vertically inserted through the threaded engagement. At the same time, one side The mounting base 505 has a vertically fixed limit post 504 on its top surface, which is used to mechanically limit the horizontal bending angle of the bending die assembly 1 to prevent accidental excessive rotation angle. With this setting, during the bending process, the limit post 504 of the bending limit assembly 5 abuts against the outside of the bending holder 101 to mechanically stop the bending angle of the bending die assembly 1. This achieves a dual angle protection system with the angle encoder 608, ensuring that when the angle encoder 608 malfunctions or the control component 7 is abnormal, the bending limit assembly 5 can still effectively prevent the bending die assembly 1 from continuing to rotate, preventing accidental excessive rotation angle and scrapping of the profile.

[0030] See Figures 1-12 As shown, the control panel body 4 is also fixedly equipped with a control component 7, which is electrically connected to the profile leveling component 3, the fixed mold component 2, the bending mold component 1, the bending drive component 6, and the discharge push component 8. This control component 7 controls the coordinated operation of each component to achieve automatic and precise control of the bending angle. Specifically, the control component 7 includes a microcomputer controller 702 and a touch screen 704. The microcomputer controller 702 is located on the top surface of the control panel body 4, and the touch screen 704 is mounted on the top surface of the microcomputer controller 702. A switch is also located next to the touch screen 704 on the microcomputer controller 702. Button 701 and emergency stop button 703 are configured such that, with the help of the microcomputer controller 702, the rotation angle signal of the support shaft 602 detected by the angle encoder 608 can be received and fed back in real time, automatically controlling the coordinated work of each component to achieve automatic and precise control of the bending angle, reducing manual intervention. At the same time, the touch screen 704 allows operators to easily set parameters such as bending angle and clamping force, making operation convenient. The emergency stop button 703 can quickly stop the machine in an emergency, ensuring the safety of the equipment and operators and reducing the accident rate. The switch button 701 can be used to start and stop the overall operation.

[0031] See Figures 1-12As shown, the following optimizations have been made to this application. Specifically, the back of the clamping plate 202 is covered with a flexible buffer pad 205, which is made of rubber. The limiting roller 105 is a wear-resistant rubber roller. This arrangement facilitates elastic buffering protection during the bending process of the profile. Optionally, the bottom and top ends of the clamping stud 501 are respectively fixed with an elastic pressure block 503 and a handle 506. This allows the clamping stud 501 to be tightened by holding the handle 506 to press the elastic pressure block 503 against the top surface of the operating table body 4, thereby preventing the upper half of the locking plane bearing 502 from rotating and thus locking the position of the limiting post 504. Optionally, a fall-prevention flange 306 is coaxially fixed to the outer periphery of the bottom surface of the flattening roller 304 at the rear position, and the adjusting groove 3081 is a waist-shaped groove arranged along the longitudinal direction. With this arrangement, it is easy to use the fall-prevention flange 306 to support and prevent the bottom of the profile from falling and detaching during the process of passing through the flattening roller 304.

[0032] With the above structure, in practical applications, since an angle encoder 608 is added to the bending drive assembly 6 and is electrically connected to the control assembly 7, the rotation angle of the support shaft 602 can be detected in real time and a feedback signal can be provided. Thus, the start and stop of the bending motor 601 can be automatically controlled by the angle encoder 608 and the control assembly 7, achieving precise adjustment and automatic control of the bending angle without disassembling or replacing the mold. Furthermore, the angle encoder 608 has high detection accuracy, ensuring precise control of the bending angle. Additionally, a bending limit assembly 5 is provided outside the bending drive assembly 6. During the bending process, the limit post 504 of the bending limit assembly 5 abuts against the outside of the bending holder 101, mechanically stopping the bending. The bending angle of the bending die assembly 1 is mechanically limited, forming a dual angle protection system with the angle encoder 608. This ensures that even if the angle encoder 608 malfunctions or the control assembly 7 is abnormal, the bending limit assembly 5 can still effectively prevent the bending die assembly 1 from continuing to rotate, preventing excessive rotation angle that could lead to profile scrapping. This improves operational safety and helps reduce scrapping costs. Furthermore, by integrating the profile leveling assembly 3, the fixed die assembly 2, the bending die assembly 1, the bending drive assembly 6, the bending limit assembly 5, and the discharge push assembly 8 onto the operating table body 4, a fully integrated operation is achieved, from profile leveling, segmented clamping, bending to discharge. This reduces manual intervention. Simultaneously, the control assembly 7 and the profile... The leveling assembly 3, fixing die assembly 2, bending die assembly 1, bending drive assembly 6, and discharge push assembly 8 are electrically connected, realizing automated control. Operators only need to set parameters using the touch screen 704 to complete the processing of the profile, eliminating the need for real-time manual monitoring of the bending angle. This helps improve processing efficiency and reduce labor intensity. Furthermore, the profile leveling assembly 3 is equipped with a polished buffer bushing 305. By using the rolling of the buffer bushing 305 to pass the profile, the surface of the profile can be leveled before bending, avoiding bending deviations caused by the profile's own bending. At the same time, the clamping plate 202 of the fixing die assembly 2 is also equipped with a flexible buffer pad 205, which can cushion and protect the profile during the clamping process. Furthermore, the limiting roller 105 of the bending die assembly 1 is made of wear-resistant rubber and can rotate around the wheel axle 104, thereby providing cushioning and protection to the surface of the profile during bending and guiding its movement during the bending process, achieving all-round flexible protection for the profile. Additionally, the profile leveling assembly 3 includes a spacing adjustment component 308, which adjusts the spacing between the two leveling rollers 304 to accommodate profiles of different thicknesses. Simultaneously, the limiting post 504 in the bending limiting assembly 5 can adjust its limiting position by rotating the plane bearing 502, thus adapting to different bending angles of the bending die assembly 1. Moreover, the clamping cylinder 201 and limiting cylinder 102 of both the fixing die assembly 2 and the bending die assembly 1 can adjust the clamping force.Therefore, it can adapt to the processing needs of glass frames with different specifications and bending angles, eliminating the need for separate equipment for different profile specifications, thus improving the equipment's applicability. Furthermore, the control component 7 is equipped with an emergency stop button 703, allowing for rapid shutdown in emergencies and preventing safety accidents caused by equipment malfunctions or operational errors. Simultaneously, the dual system of "electronic precision angle control + mechanical safety limit" not only improves angle control accuracy but also avoids potential malfunctions that may occur with a single angle control method, contributing to improved operational safety and equipment stability, and reducing equipment maintenance frequency and costs.

[0033] See Figures 1-12 As shown, the workflow in the actual process is briefly described as follows: First, the operator sets the processing parameters through the touch screen 704 and adjusts the spacing between the upper and lower sets of leveling rollers 304 through the spacing adjustment component 308; then, the profile is fed laterally into the profile leveling assembly 3, and the feeding motor 301 drives the leveling rollers 304 to rotate, leveling the profile and eliminating bending deformation in the thickness direction; after leveling, the profile continues to move, and the left half enters the fixed seat 203 of the fixed mold assembly 2. The clamping cylinder 201 drives the clamping plate 202 to move and press the left half of the profile; the right half of the profile enters the bending mold assembly 1, and the limiting cylinder 102 drives the wheel frame 103 to move so that the limiting roller 105 is in close contact with the right half of the profile, realizing flexible clamping and limiting; then, the bending motor 601 starts, driving the support shaft 602 to rotate around the Y direction, driving the bending disc 604. As the arc-shaped top block 603 rotates, the right half of the profile rotates with the bending holder 101 for cold bending. The angle encoder 608 detects the rotation angle of the support shaft 602 in real time and transmits the signal to the control component 7. When the preset bending angle is reached, the control component 7 controls the bending motor 601 to stop rotating. During the bending process, if the angle encoder 608 or the control component 7 malfunctions, when the bending die assembly 1 rotates to the bending angle, the limit post 504 will abut against the bending holder 101 to prevent it from continuing to rotate, thus achieving mechanical safety limiting. After bending is completed, the clamping cylinder 201 and the limit cylinder 102 are reset, and the push cylinder 801 drives the push rod 803 to move upward, pushing the bent profile out from the top of the fixed holder 203 and the bending holder 101, completing the unloading. By repeating the above process, the integrated cold bending processing of batch profiles can be realized.

[0034] See Figures 1-12As shown, in practical applications, multiple combined synergistic effects are implemented. Specifically, the combined synergistic effect of integrated design and dual angle control system is achieved: integrated design ensures coordinated operation of all components, allowing the dual angle control system to play its full role—the precise detection signal from the angle encoder 608 can be transmitted to the control component 7 in real time, and the control component 7 synchronously controls the start and stop of the bending drive component 6, while the bending limit component 5 is on standby in real time, avoiding signal delay and limit failure caused by component dispersion; conversely, the accuracy and safety of the dual angle control system ensure the smoothness of integrated operation and avoid process interruption caused by angle deviation. The combination of the two results in a double improvement in processing efficiency and accuracy, far exceeding the effect of "single integration + single angle control".

[0035] The combined efficiency of automated control and multi-component optimization: The control component 7 is linked with the angle encoder 608, clamping cylinder 201, limit cylinder 102, push cylinder 801, bending motor 601, and feeding motor 301 to achieve parameter preset, automatic adjustment, and real-time monitoring. At the same time, with the optimized structure of the spacing adjustment component 308 and the position-adjustable limit column 504, the equipment can quickly adapt to different specifications of profiles without repeated manual adjustments, forming a synergistic effect of "automated control → multi-specification adaptation → high-efficiency processing". Its processing efficiency and ease of operation far exceed the effect of "single automation + single component optimization".
