Description

Technical Field

[0001] This invention relates to the field of bent tempered glass, and more specifically, to a bent tempered glass forming apparatus and method. Background Technology

[0002] Curved tempered glass is a type of curved glass that has undergone heating, bending, and tempering. Due to its excellent curved surface shape, compressive strength, and safety performance, it is widely used in architectural curtain walls, automotive windows, appliance glass, and decorative moldings. In the large-scale production of curved tempered glass, the precision of the bending process directly determines the quality of the finished product and is the core of the entire processing.

[0003] Currently, traditional curved glass forming equipment mostly uses integral arc molds for shaping, with a fixed mold curvature that cannot be flexibly adjusted according to production needs, resulting in poor adaptability. At the same time, the load-bearing pressure roller frames of existing forming equipment are mostly fixed structures. During the glass conveying and bending extrusion process, the hinge position between the pressure roller and the mounting base is subjected to extrusion and friction loads for a long time, which can easily lead to problems such as wear of the hinge hole, increased fit clearance, and coaxiality misalignment.

[0004] Existing technologies lack targeted wear detection structures, making it impossible to detect minor wear hazards at hinge points in a timely manner. Long-term use can lead to uneven local stress during glass bending and forming, resulting in quality defects such as irregular curved surfaces, curvature deviations, and surface wrinkles, significantly increasing the product defect rate. In addition, the poor linkage between the forming, conveying, and station switching structures of traditional equipment and insufficient operational stability further affect the processing accuracy and production efficiency of bent tempered glass. Summary of the Invention

[0005] The purpose of this invention is to provide a bending glass forming device that solves the technical problems of existing forming equipment, such as inconvenient curvature adjustment, easy wear of hinge parts, lack of self-inspection function, low glass forming accuracy, and poor operation stability. It realizes flexible glass bending forming, automatic wear detection, and coaxiality error compensation, thereby improving product processing quality and production stability.

[0006] This invention is implemented as follows: The present invention provides a bending steel glass forming device, including a processing section disposed between a feeding roller and a conveying roller. The processing section includes an upper arc-shaped die and a lower arc-shaped die. The upper arc-shaped die is composed of multiple die rollers A arranged in an arc shape and is driven by an external vertical drive mechanism to perform vertical linear lifting and lowering motion.

[0007] The lower arc-shaped die includes a pressure roller B and a pressure roller frame. The pressure roller frame is assembled from multiple connecting seats that are hinged end to end. The pressure roller B is rotatably mounted at the hinge point of two adjacent connecting seats. Two adjacent pressure rollers B are connected by a transmission component. An external motor can drive any one pressure roller B to rotate all pressure rollers B synchronously.

[0008] When all pressure rollers B are in a horizontal arrangement, the glass to be processed is conveyed from the feed roller to the upper arc-shaped die by the rotation of the pressure rollers B. Then, the external lifting mechanism pulls the pressure roller frame diagonally upward from both ends, causing the entire pressure roller frame to bend into an arc shape. The lower arc-shaped die after bending cooperates with the descending upper arc-shaped die to extrude and complete the glass bending process. After the glass processing is completed, the lifting force is removed, the pressure roller frame returns to a horizontal state, and the upper arc-shaped die is lifted by the vertical drive mechanism to avoid the formed glass. Then, the formed arc-shaped glass is sent out to the feed roller side by the rotation of the pressure rollers B.

[0009] Furthermore, the two adjacent connecting seats are staggered and overlapped, and perforations are opened at the staggered and overlapped ends. The rotating shaft of the pressure roller B is coaxially connected and assembled with the perforations.

[0010] Furthermore, a set of pressure roller frames is provided at both ends of the axial direction of each pressure roller B, and the rotation and pressure bearing stability of the pressure roller B is improved by the limiting support of the double pressure roller frames on both sides.

[0011] Furthermore, a connecting rod is hinged to the connecting seat, and a guide rod is hinged to the other end of the connecting rod; a guide rod groove extending along the bending direction is opened on the side of the pressure roller frame, and the guide rod is limited and embedded in the guide rod groove and slides linearly along the groove to limit the bending trajectory of the connecting seat.

[0012] Furthermore, the device also includes a rail arranged below the processing section; when the pressure roller frame is in a horizontal position, the bottom surface of each connecting seat supports the top surface of the rail, and the pressure roller frame is limited in load-bearing capacity during glass conveying by relying on the rail, thereby improving conveying stability.

[0013] Furthermore, the connecting rail includes a fixed rail and a moving rail. The moving rail slides vertically along the top surface of the fixed rail via a vertical positioning rod, and the bottom surface of the connecting seat is mounted on the upper surface of the moving rail. The fixed rail has a U-shaped groove structure, and a sliding rod is slidably assembled in the groove cavity along its own length. The sliding rod is connected to the side wall of the moving rail through a connecting rod assembly. When the sliding rod slides back and forth, it drives the moving rail to rise and fall via the connecting rod assembly, realizing the switching of the moving rail supporting or disengaging from the bottom surface of the connecting seat.

[0014] This device is also equipped with a pressure roller mounting rod. Under normal conditions, the pressure roller mounting rod is located directly below the pressure roller B and does not contact the pressure roller B. During the sliding process of the slide rod, the support rod assembly is driven to lift the pressure roller mounting rod, and the pressure roller mounting rod supports the pressure roller B from below.

[0015] Furthermore, two connecting seats located in the middle of the entire pressure roller frame are fixed on the fixed rail, and the outer walls of the two connecting seats are provided with detection shafts protruding outward; a detection mechanism for monitoring the radial runout of the detection shaft is assembled on the fixed rail; when the upper arc-shaped pressure mold and the lower arc-shaped pressure mold close and squeeze the glass, causing the gap between the pressure roller B and the perforation to increase, the connecting seats and the detection shaft will produce abnormal shaking, and the detection mechanism will determine the perforation and hinge wear faults by collecting the runout data of the detection shaft.

[0016] Furthermore, the detection mechanism includes an arc-shaped seat and a detection arc seat embedded inside the arc-shaped seat. An elastic buffer and a pressure sensor are arranged between the detection arc seat and the arc-shaped seat. During the normal conveying station of the equipment, the moving rail supports the connecting seat, and there is no squeezing contact between the detection shaft and the detection arc seat, so the pressure sensor is unloaded. During the self-inspection station of the equipment, the moving rail descends and disengages from the connecting seat, and the pressure roller mounting rod rises to support the pressure roller B, suspending the connecting seat. The arc-shaped seat drives the detection arc seat to rotate circumferentially around the detection shaft for inspection. If the value collected by the pressure sensor deviates from the preset threshold, it is determined that the perforation at the corresponding position has worn, and the equipment controller outputs a wear alarm, realizing all-round detection of coaxial wear of the perforation.

[0017] Furthermore, the arc-shaped seat is fixedly installed on the connecting plate seat, and multiple sets of connecting plate seats are driven in conjunction via a gear transmission group; the gear transmission group includes mutually meshing driving gears and driven gears, and all driving gears are synchronously driven by the same transmission belt; the device is also equipped with a pair of split clamping plates, and the two clamping plates form a limiting adjustment hole adapted to the outer diameter of the pressure roller B after they are put together; when the detection mechanism detects that the perforation wear exceeds the standard, the clamping plates are locked by means of bolts passing through the annularly distributed bolt holes on the connecting seat, and the clamping plates hold the limiting pressure roller B, correcting the coaxiality of the pressure roller B and the perforation, and compensating for the perforation wear gap.

[0018] The beneficial effects of this invention are: 1. This invention adopts a bendable hinged pressure roller frame structure. The pressure roller frame can be bent into an arc shape by lifting mechanisms at both ends. It is used in conjunction with a fixed arc-shaped upper arc-shaped pressure mold to complete the glass bending and forming. It can flexibly adapt to the processing of bent steel glass with different curvatures, breaking through the limitation of the single curvature of the traditional fixed mold, and the equipment has stronger adaptability.

[0019] 2. The present invention features a switchable rail support structure. By switching between fixed rail and moving rail, it can flexibly switch between normal conveying support and fault self-inspection station. Together with the pressure roller mounting rod, it can achieve stable support of the pressure roller in the self-inspection state, ensuring the stability and accuracy of the inspection process.

[0020] 3. This invention adds a dedicated wear detection mechanism, which can perform all-round circumferential detection on the wear gap and coaxiality deviation of the connecting seat perforation and the hinge position of the pressure roller B. It can detect the small wear hazards of the equipment in time and alarm, solving the problem of traditional equipment lacking self-inspection function and wear accumulation leading to irregular glass forming, and greatly improving the processing accuracy of finished products.

[0021] 4. This invention is equipped with a split clamping plate error compensation structure. For perforation positions with excessive wear, the clamping plates can hold the limiting pressure roller tightly to quickly correct coaxiality deviation and compensate for wear gaps. Error correction can be achieved without disassembling the machine for maintenance, reducing equipment maintenance costs and ensuring long-term processing stability.

[0022] 5. This invention effectively improves the stability of the pressure roller operation and the bending process of the pressure roller frame through the double-sided pressure roller frame and the connecting rod guide groove limiting structure, avoiding deviation and shaking. At the same time, the full roller synchronous transmission structure ensures that the glass is conveyed at a uniform and stable speed, further improving the forming quality and production efficiency of bent steel glass.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example Reference Figures 1-8 A bending glass forming device includes a processing section installed between the feed roller and the feeding roller. The processing section, as the core station for glass bending forming, mainly consists of an upper arc-shaped mold 1 and a lower arc-shaped mold 2.

[0028] Reference Figure 1 and Figure 2 The upper arc-shaped pressure mold 1 is composed of multiple arc-shaped pressure rollers A, forming a fixed arc structure. Driven by an external vertical drive mechanism, it can achieve stable vertical lifting and lowering, completing the mold closing and demolding avoidance actions. In some embodiments, the pressure rollers A are mounted on a mounting base, and the vertical drive mechanism drives the pressure rollers A to move up and down by driving the mounting base. When the pressure rollers A move downward, they cooperate with the lower arc-shaped pressure mold 2 to press and position the glass. When the pressure rollers A move upward, they release the positioning of the glass and provide space for the forward conveying of the bent arc-shaped glass, preventing the upper arc-shaped pressure mold 1 from obstructing the conveying of the bent arc-shaped glass.

[0029] Reference Figures 1-4 In this embodiment, the lower arc-shaped pressure mold 2 consists of a pressure roller B20 and a pressure roller frame 21. The pressure roller frame 21 is assembled from multiple connecting seats 210 that are hinged end to end, and has two working states: horizontal flattening and arc bending. It should be added that: when the pressure roller frame 21 switches from horizontal flattening to arc bending, it can be lifted from both sides by lifting rods or ropes, causing the pressure roller frame 21 to bend in an arc.

[0030] In other embodiments, the lifting device includes an oblique lifting drive assembly, a hinged lug, a lifting rod, and a limiting guide assembly symmetrically arranged at both ends of the pressure roller frame. The lifting devices at both ends employ synchronous linkage control to ensure uniform force distribution and symmetrical bending curvature on both sides of the pressure roller frame, preventing misalignment in glass forming due to unilateral deviation. Specifically, the hinged lug is fixedly welded or bolted to the end of the outermost connecting seat of the pressure roller frame, serving as the lifting force point; the lower end of the lifting rod is hinged to the hinged lug, and the upper end of the lifting rod is obliquely connected to the lifting drive assembly, forming an overall obliquely upward lifting force structure, thus achieving the deformation principle of the pressure roller frame of this device: "oblique pulling at both ends and natural arching in the middle for forming."

[0031] Reference Figure 3 and Figure 4 The adjacent connecting seats 210 adopt a staggered overlapping structure design, with coaxial through holes 2100 at the overlapping positions. The rotating shaft of the pressure roller B20 is rotatably assembled inside the through holes 2100, enabling the pressure roller B20 to rotate flexibly. At the same time, pressure roller frames 21 are provided at both ends of the axial direction of each pressure roller B20. Through double-sided support and limiting, the stability of the pressure roller B20 during pressure bearing and rotation is greatly improved, avoiding offset and swaying caused by single-sided support.

[0032] To further limit the bending trajectory of the pressure roller frame 21 and prevent misalignment or displacement during bending, a connecting rod 211 is hinged to the connecting seat 210. One end of the connecting rod 211 is hinged to a guide rod 212. A suitable guide rod groove 213 is opened on the side wall of the pressure roller frame 21. The guide rod 212 is embedded in the guide rod groove 213 and can slide linearly along the groove. During the bending deformation of the pressure roller frame 21, the connecting rod 211 and the guide rod 212 cooperate to form a limiting and guiding structure, ensuring that all connecting seats 210 bend synchronously and regularly, and ensuring that the forming arc is uniform.

[0033] Furthermore, adjacent pressure rollers B20 are linked together via a transmission assembly. When the equipment is working, an external motor drives any one pressure roller B20 to rotate, which in turn drives all pressure rollers B20 to rotate synchronously in the same direction. During the glass conveying stage, the pressure roller frame 21 is in a horizontal and flat state, achieving stable glass conveying. During normal processing, the pressure roller frame 21 remains horizontal, and the rotation of the pressure rollers B20 accurately conveys the glass to be processed from the feed roller to directly below the upper arc-shaped mold 1. Subsequently, the vertical drive mechanism drives the upper arc-shaped mold 1 to descend, while the external lifting mechanism lifts the pressure roller frame 21 obliquely upward at a uniform speed from both ends, causing the hinged pressure roller frame 21 to slowly bend into an arc shape, cooperating with the upper arc-shaped mold 1 to squeeze the glass and complete the bending forming process.

[0034] It should be noted that: in order to ensure rigid extrusion contact between pressure roller A and pressure roller B20, rubber buffer sleeves can be fitted on the outer walls of pressure roller A and pressure roller B20; in addition, to ensure uniform bending, pressure roller A and pressure roller B20 are staggered.

[0035] After the glass is formed, the lifting mechanism releases the force, and the pressure roller frame 21 returns to a horizontal state by its own structure. At the same time, the upper arc-shaped mold 1 is raised to avoid the formed arc-shaped glass. Finally, the finished glass is smoothly transported to the feeding roller by the continuous rotation of the pressure roller B20, completing a single processing cycle.

[0036] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 To ensure the stability of the equipment during horizontal conveying, a rail 3 is installed below the processing section. The rail 3 includes a fixed rail 30 and a movable rail 31 that can be raised and lowered. The movable rail 31 achieves precise vertical sliding through a vertical positioning rod at its bottom. When the pressure roller frame 21 is horizontally unfolded, the bottom surfaces of all connecting seats 210 are mounted on the top surface of the movable rail 31. Through the overall support of the movable rail 31, the pressure roller frame 21 is prevented from swaying in the air during glass conveying, ensuring smooth conveying.

[0037] Reference Figure 5 and Figure 6 The fixed rail 30 adopts a U-shaped groove structure, with a sliding rod 300 slidably mounted inside. The sliding rod 300 is connected to the side wall of the moving rail 31 through a connecting rod assembly 301. When the sliding rod 300 slides back and forth along the length of the fixed rail 30, it can drive the moving rail 31 to rise and fall as a whole through the connecting rod assembly 301, realizing the switching of support and disengagement of the moving rail 31 to the connecting seat 210. At the same time, a pressure roller mounting rod 32 is provided inside the fixed rail 30. Under normal conditions, the pressure roller mounting rod 32 is located directly below the pressure roller B20 and does not contact it, so it does not affect the normal operation of the equipment. When the sliding rod 300 slides to switch positions, it synchronously drives the support rod assembly 320 (an inclined connecting rod, the inclination direction of which is opposite to the inclination direction of the connecting rod assembly 301) to lift the pressure roller mounting rod 32, so that the pressure roller mounting rod 32 is raised and supports the pressure roller B20, providing stable support for the equipment's self-inspection position.

[0038] In this embodiment, to achieve automatic wear detection of the equipment, two connecting seats 210 in the middle of the entire pressure roller frame 21 are fixedly installed on the fixed rail 30; in addition, a detection shaft 2101 is integrally protruding from the outer wall of the connecting seat 210, and a corresponding detection mechanism 4 is assembled on the fixed rail 30. (Refer to...) Figure 6 and Figure 7 The detection mechanism 4 consists of an arc-shaped seat 40 and a built-in detection arc seat 41. An elastic buffer and a pressure sensor are assembled between the arc-shaped seat 40 and the detection arc seat 41 to detect changes in contact pressure in real time. The detection mechanism 4 is mounted on the connecting plate seat 5. The elastic buffer can be an elastic structure such as a spring or a rubber buffer pad, which causes relative movement between the arc-shaped seat 40 and the detection arc seat 41 after being subjected to force.

[0039] In the normal production station, the moving rail 31 supports the connecting seat 210, and the detection shaft 2101 contacts the detection arc seat 41. When the equipment enters the self-inspection mode, the slide bar 300 slides, causing the moving rail 31 to descend and disengage from the connecting seat 210. At the same time, the pressure roller mounting rod 32 lifts up to support the pressure roller B20, so that the connecting seat 210 is in a suspended state. At this time, the gear transmission group 6 works, and through the meshing of the driving gear and the driven gear, it drives multiple sets of connecting disc seats 5 to rotate synchronously with the transmission belt, thereby driving the arc seat 40 and the detection arc seat 41 to rotate circumferentially around the detection shaft 2101.

[0040] During the rotational testing process, if the perforation 2100 is worn or the clearance increases, the connecting seat 210 will wobble radially, causing the detection shaft 2101 to press against the detection arc seat 41, resulting in abnormal fluctuations in the pressure sensor value. When the value deviates from the preset threshold, the controller immediately triggers an alarm, accurately locates the wear fault position, and realizes all-round wear detection at the hinge position between the perforation 2100 and the pressure roller B20.

[0041] To address the detected wear defects, this invention incorporates an error compensation structure, referring to... Figure 8 This refers to a pair of split clamping plates 7. When the two clamping plates 7 are aligned, they form a limiting hole that matches the outer diameter of the pressure roller B20. The operator can use bolts to lock and fix the clamping plates 7 in the abnormally worn hinge position by using bolts arranged in a ring on the connecting seat 210. By clamping the pressure roller B20 with the clamping plates 7, the wear gap of the perforation 2100 is effectively compensated, and the coaxiality deviation between the pressure roller B20 and the perforation 2100 is corrected. This avoids the problem of local irregularities in glass bending caused by excessive gap and coaxiality deviation. There is no need to disassemble the machine to replace parts, which greatly reduces the equipment maintenance cost and ensures long-term high-precision operation of the equipment.

[0042] In this embodiment, the connecting seat 210 located in the middle of the entire pressure roller frame 21 is not fixed on the fixed rail 30. When testing, the pressure roller mounting rod 32 moves upward, thereby horizontally supporting the entire connecting seat 210. This also allows for testing of the middle pressure roller frame 21.

[0043] This glass bending forming device uses an adaptively bendable lower arc-shaped die in conjunction with a fixed upper arc-shaped die to achieve flexible glass bending. It also integrates automatic station switching, wear self-inspection, and coaxiality error compensation functions. The overall workflow is divided into four core stages: glass conveying and feeding, glass bending and forming, finished product discharge and resetting, and equipment self-inspection and error calibration. The specific steps are as follows: S1, the glass conveying and loading stage (horizontal standby station) process is as follows: 1. In the initial state of the equipment, the pressure roller frame is kept horizontal and flat. The moving rail above the fixed rail is in the raised position, providing full support to the bottom of all connecting seats. With the pressure roller frame arranged on both sides, the pressure roller B is placed horizontally without deviation or shaking, and the equipment is in a stable standby state.

[0044] 2. An external drive motor operates, driving all pressure rollers B to rotate synchronously and in the same direction through a transmission assembly, forming a continuous conveying table. The glass to be processed is fed into the processing area of ​​the equipment by the feed rollers, and is smoothly conveyed by the uniformly rotating pressure rollers B, accurately delivered to the forming station directly below the upper arc-shaped die, completing the loading and positioning.

[0045] 3. During the conveying process, the connecting rod, guide rod and guide groove on the connecting seat form a limiting and guiding structure, which constrains the structural stability of the pressure roller frame in a horizontal state, avoids misalignment and offset of the connecting seat during the conveying process, and ensures that the glass is conveyed flat and at a uniform speed without jamming or warping.

[0046] S2, the glass bending and forming stage (arc-shaped mold closing station) process is as follows: 1. After the glass is positioned, the external vertical drive mechanism drives the upper arc-shaped mold to move downward at a uniform speed, close to the surface of the glass to be processed, and leaving a forming extrusion allowance.

[0047] 2. The external lifting mechanism lifts the pressure roller frame at an angle and upward at a uniform speed from both ends, causing the multiple connecting seats that are hinged at the ends to bend and deform synchronously. The whole structure slowly bends from a horizontal state to a preset arc shape, which drives the glass to be processed above to bend and shape synchronously.

[0048] 3. During the bending process, the guide rod slides linearly along the guide rod groove, limiting the bending trajectory of all connecting seats, ensuring that the curvature of the entire pressure roller frame is uniform and symmetrical, without local protrusions or depressions, so that the glass is subjected to uniform force.

[0049] 4. The lower arc-shaped die after bending precisely matches the upper arc-shaped die after descending to the position, and flexibly extrudes and shapes the heated glass to complete the bending and forming process of the bent tempered glass, ensuring that the curvature of the glass surface is regular and the forming accuracy is high.

[0050] S3, the finished product discharge and equipment reset process is as follows: 1. After the glass is formed, the lifting mechanism removes the oblique lifting force, the pressure roller frame loses the external force constraint, and relies on its own hinge structure to reset, returning from the arc state to the initial horizontal flat state.

[0051] 2. The vertical drive mechanism lifts the upper arc-shaped mold upwards, away from the surface of the formed glass, effectively avoiding the curved glass and preventing damage or deformation caused by scratching or squeezing the glass during demolding.

[0052] 3. The pressure roller B continues to rotate, driving the formed curved glass to move smoothly towards the feeding roller, completing the finished product discharge. The single glass forming process is completed, and the equipment returns to the horizontal standby position, waiting for the next feeding process.

[0053] S4. Equipment Wear Self-Inspection and Error Calibration Stage (Intermittent Self-Inspection Station): The process is as follows: This device can automatically enter self-inspection mode during equipment downtime or at a set cycle to realize wear detection and error compensation of hinged parts. The specific steps are as follows: 1. Workstation switching: The slide bar slides along the length of the fixed rail, and the moving rail is driven to descend as a whole through the linkage assembly, so that the moving rail is separated from the bottom of the connecting seat and the support of the pressure roller frame is released; at the same time, the slide bar linkage support rod assembly lifts the pressure roller mounting rod, and the pressure roller mounting rod stably supports all pressure rollers B from below, so that the connecting seat is in a suspended state for testing.

[0054] 2. Full-range detection: The gear transmission group works, and multiple sets of connecting disc seats rotate synchronously through the transmission belt, driving the arc-shaped seat and the internal detection arc seat to rotate circumferentially around the detection axis of the central connecting seat; during the detection process, the pressure sensor collects contact pressure data in real time, and detects the wear gap and coaxiality deviation at the hinge position between the perforation and the pressure roller B throughout the process.

[0055] 3. Fault diagnosis: If there is wear in the perforation and the fit clearance increases, the connecting seat will wobble radially, causing the detection shaft to squeeze the detection arc seat, causing the pressure sensor value to deviate from the preset threshold. The system will automatically determine that the hinge structure at this position is abnormally worn and issue a fault reminder through the controller to accurately locate the wear point.

[0056] 4. Error calibration: For the detected abnormal wear locations, a pair of split clamping plates are assembled together and locked in place by bolts through the bolt holes arranged in a ring on the connecting seat. The clamping plates hold the pressure roller B tightly, compensating for the gap caused by the wear of the perforation, correcting the coaxiality deviation between the pressure roller B and the perforation, and eliminating the local irregular shape defects in glass forming caused by equipment wear.

[0057] 5. Self-test reset: After the test and calibration are completed, the slide bar slides in the opposite direction, driving the pressure roller mounting rod to descend and reset, and the moving rail to rise and reset, re-supporting the connecting seat. The equipment exits the self-test mode and resumes normal glass processing.

[0058] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.

The bending steel glass forming device according to claim 4, characterized in that, It also includes a rail (3) arranged below the processing section; when the pressure roller frame (21) is in a horizontal position, the bottom surface of each connecting seat (210) is supported on the top surface of the rail (3), and the pressure roller frame (21) is limited in load-bearing capacity during glass conveying by relying on the rail (3).

6. The bending steel glass forming apparatus according to claim 5, characterized in that, The connecting rail (3) includes a fixed rail (30) and a moving rail (31). The moving rail (31) slides vertically along the top surface of the fixed rail (30) via a vertical positioning rod. The bottom surface of the connecting seat (210) is mounted on the upper surface of the moving rail (31). The fixed rail (30) has a U-shaped groove structure. A slide rod (300) is slidably mounted in the groove cavity of the fixed rail (30) along its own length direction. The slide rod (300) is connected to the side wall of the moving rail (31) through the connecting rod assembly (301). When the slide rod (300) slides back and forth, it drives the moving rail (31) to rise and fall through the connecting rod assembly (301), so as to realize the support or disengagement of the moving rail (31) on the bottom surface of the connecting seat (210). It is also equipped with a pressure roller mounting rod (32). Under normal conditions, the pressure roller mounting rod (32) is located directly below the pressure roller B (20) and does not contact the pressure roller B (20). During the sliding process of the slide rod (300), the support rod assembly (320) is driven to lift the pressure roller mounting rod (32), and the pressure roller B (20) is supported from below by the pressure roller mounting rod (32).

7. The bending steel glass forming apparatus according to claim 6, characterized in that, The connecting seat (210) located in the middle of the entire pressure roller frame (21) is fixed on the fixed rail (30); the outer wall of the connecting seat (210) is provided with a detection shaft (2101) protruding outward; The fixed rail (30) is equipped with a detection mechanism (4) for monitoring the radial runout of the detection shaft (2101); when the wear gap between the pressure roller B (20) and the perforation (2100) increases, the connecting seat (210) and the detection shaft (2101) will shake abnormally. The detection mechanism (4) will determine the wear fault of the perforation (2100) and the hinge position by collecting the runout data of the detection shaft (2101), so as to avoid the glass forming irregular shape caused by uneven hinge gap.

8. The bending steel glass forming apparatus according to claim 7, characterized in that, The detection mechanism (4) includes an arc-shaped seat (40) and a detection arc seat (41) embedded inside the arc-shaped seat (40). An elastic buffer and a pressure sensor are arranged between the detection arc seat (41) and the arc-shaped seat (40).

9. The bending steel glass forming apparatus according to claim 8, characterized in that, The arc-shaped seat (40) is fixedly installed on the connecting plate seat (5), and multiple sets of connecting plate seats (5) are driven in linkage via a gear transmission group (6); the gear transmission group (6) includes meshing driving gears and driven gears, and all driving gears are synchronously driven by the same transmission belt. It is also equipped with a pair of split clamping plates (7). After the two clamping plates are put together, they form a limiting adjustment hole that matches the outer diameter of the pressure roller B (20). When the detection mechanism detects that the wear of the perforation (2100) exceeds the standard, the clamping plate (7) is locked by passing a bolt through the annularly distributed bolt holes on the connecting seat (210). The clamping plate (7) holds the limiting pressure roller B (20) tightly, corrects the coaxiality of the pressure roller B (20) and the perforation (2100), compensates for the wear gap of the perforation (2100), and prevents the glass bending and local deformation defects caused by excessive hole wear gap.

10. A method for forming bent tempered glass, using the bending tempered glass forming apparatus according to claim 9, characterized in that, Includes the following steps: S1. Glass conveying and feeding stage: The pressure roller frame is kept horizontal and flat. The external drive motor works and drives all pressure rollers B to rotate synchronously in the same direction through the transmission component to form a continuous conveying table. The glass to be processed is fed into the processing area of ​​the equipment by the feeding roller. It is smoothly conveyed by the pressure rollers B rotating at a uniform speed and accurately delivered to the forming station directly below the upper arc-shaped mold to complete the feeding and positioning. S2, Glass Bending and Forming Stage: The external vertical drive mechanism drives the upper arc-shaped mold to move downward at a uniform speed, close to the surface of the glass to be processed, and leaves a forming extrusion allowance; the external lifting mechanism lifts the roller frame at a uniform speed from the left and right ends, so that the multiple connecting seats with hinged ends are bent and deformed synchronously, and the whole is slowly bent from a horizontal state to a preset arc shape, which drives the glass to be processed above to be bent and shaped synchronously. S3. Finished Product Discharge and Equipment Reset Stage: After the glass is formed, the lifting mechanism removes the oblique lifting force, the pressure roller frame loses the external force constraint, and resets itself by relying on its own hinge structure, returning from the arc state to the initial horizontal flat state; the vertical drive mechanism drives the upper arc mold to rise upward, and the pressure roller B continues to rotate, driving the formed arc glass to move smoothly towards the feeding roller, completing the finished product discharge.
