Description

Technical Field

[0001] This invention relates to the field of quartz tube drawing and forming technology, specifically to a quartz tube drawing and forming device for quartz tube production. Background Technology

[0002] Quartz glass tubes are a type of special industrial technical glass with silicon dioxide as the main component. They have characteristics such as high temperature resistance, corrosion resistance, good thermal stability, and excellent light transmission performance, and are widely used in high-tech fields such as semiconductors, photovoltaics, and aerospace.

[0003] Currently, there is a quartz glass tube drawing and forming device. When the traction equipment stretches the quartz tube, the entire tube drawing production line is stopped when the quartz tube reaches the preset cutting length. Then, the stationary quartz tube is cut by the cutting device. After the cutting is completed, the traction component is restarted to return to its original position and continue the next round of tube drawing and cutting cycle.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that when the quartz tube reaches the preset cutting length, the traction equipment stops operating, the entire tube drawing production line enters a shutdown state, and then the cutting device cuts the stationary quartz tube. After the cutting is completed, the traction equipment is restarted to continue the next round of tube drawing and cutting cycle. This means that the entire line must be stopped to wait for the cutting action to be completed each time, which restricts the capacity utilization of the tube drawing production line. Summary of the Invention

[0005] This invention provides a tube drawing and forming device for quartz tube production, which solves the problem of limiting the capacity of tube drawing production lines due to the need for a complete line shutdown for cutting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tube drawing and forming device for quartz tube production, comprising a forming guide device, a testing device, a quartz tube, and a traction assembly.

A bracket is installed on the first sliding frame. The other end of the bracket is connected to the traction assembly. A slot is provided inside the first sliding frame.

[0007] By adopting the above technical solution, the position of the U-shaped insert is adjusted by the telescopic rod, and a separable rigid connection between the bearing ring and the traction component is achieved with the slot. This allows the traction component to continuously pull the quartz tube forward, and drive the bearing ring to slide synchronously through the insertion lock, thus achieving follow-up cutting. At the same time, by setting a rotating ring driven by a transmission motor inside the bearing ring, the cutting equipment is installed on the inner wall of the rotating ring, so that it can rotate and cut around the quartz tube circumferentially while moving axially with the bearing ring. Combined with the synchronous clamping of the tube walls on both sides of the cutting point by the first and second electric push rods, and the uniform internal support of the inner wall of the end of the quartz tube by multiple sets of clamping plates inside the pull cylinder, a double stable constraint of the inner and outer walls is formed. With the linkage between the second inclined plate on the side of the traction component and the inclined surface of the first inclined plate of the material picking component, the traction component itself moves to drive the receiving frame to lift and pick up the material.

[0010] Preferably, the traction assembly includes a storage tube, which is installed at one end of the bracket. A third electric push rod and a limiting plate are respectively installed at both ends of the storage tube. A pull tube is slidably connected inside the limiting plate, and the moving end of the third electric push rod extends into the storage tube and connects to one end of the pull tube. An annular groove is formed on the edge of one end of the limiting plate, and a first pressure sensor is provided inside the annular groove.

[0011] Preferably, the traction assembly further includes a support rod and an inlet / outlet groove. The support rod is located at the center of one end of the pull tube. One end of the support rod is connected to a mounting plate. Multiple sets of guide grooves are formed around the mounting plate. A retaining plate is slidably connected inside the guide groove. The inlet / outlet groove is formed around the inside of the pull tube.

[0012] Preferably, the traction assembly further includes a fourth electric push rod and an anti-slip pad. The fourth electric push rod is located at the axis of one end of the pull cylinder away from the support rod. The moving end of the fourth electric push rod is connected to the push plate. Multiple sets of connecting rods are arranged around the push plate. The other end of the connecting rod is connected to the clamping plate. A material picking assembly is provided on one side of the traction assembly.

[0013] Preferably, the outer edge area of ​​the card plate is provided with an anti-slip pad, and the middle area of ​​the outer side of the card plate is provided with a second pressure sensor.

[0014] Preferably, the material handling assembly includes a second sliding frame, which is slidably mounted on a guide rail. A sleeve is installed on the second sliding frame, and a sleeve rod slides through the inside of the sleeve. A third spring is provided between the sleeve rod and the inside of the sleeve. One end of the sleeve rod is connected to a receiving frame, and a discharge plate is connected to the edge of the receiving frame. The receiving frame is provided with an inclined surface.

[0015] Preferably, the material handling assembly further includes a first inclined plate and a second inclined plate.

[0016] Preferably, a conveying device is placed on one side of the guide rail.

[0017] This invention provides a tube drawing and forming apparatus for quartz tube production. It has the following beneficial effects: 1. This invention adjusts the axial position of the U-shaped insert by setting a telescopic rod, and achieves a separable rigid connection between the bearing ring and the traction component by cooperating with the slot on the first sliding frame. During the cutting process, the traction component can drive the bearing ring to slide synchronously along the bearing rod through plug-in locking, realizing online follow-up cutting of quartz tubes in a continuous forward state, and improving the continuous production capacity and output efficiency of the tube drawing production line.

[0018] 2. This invention sets up a rotating ring driven by a transmission motor inside the bearing ring, and installs the cutting equipment on the inner wall of the rotating ring. This allows the cutting equipment to move synchronously along the axial direction with the bearing ring while rotating circumferentially around the quartz tube to complete circumferential cutting. This achieves the coordination of the two cutting movements: axial following and circumferential rotation. In addition, the first and second electric push rods synchronously clamp and fix the tube walls on both sides of the cutting point, and multiple sets of clamping plates driven by the fourth electric push rod inside the pull cylinder provide internal support for the inner wall of the quartz tube end, thus achieving dual stable constraints on the inner and outer walls of the tube during the cutting process.

[0019] 3. The present invention sets a second inclined plate on the traction component to cooperate with the inclined surface of the first inclined plate of the material taking component. The traction component itself moves to drive the receiving frame to rise and fall, thereby receiving and guiding the finished quartz tube. In addition, the receiving frame is automatically reset by a third spring. At the same time, in the reset state, the receiving frame completely gives way to the tube travel channel, avoiding interference with the position of subsequent tubes. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 8This invention provides a tube drawing and forming device for quartz tube production, including a forming guide device 1, a testing device 2, a quartz tube 3, and a traction component 6. The top side of the testing device 2 is equipped with a first electric slide table 4 and a second electric slide table 5. The bottom side of the testing device 2 is equipped with a guide rail 10. The middle side of the testing device 2 is also equipped with a bearing rod 7. A bearing ring 8 is installed on the bearing rod 7. A cutting component is provided inside the bearing ring 8. A first push plate 906 is provided on the outer wall of the bearing ring 8. A second push plate 907 is installed at one end of the slider of the second electric slide table 5. A transmission component is provided between the bearing ring 8 and the traction component 6. Specifically, the forming guide device 1 is located at the front end of the device and is used to guide and support the continuously drawn quartz tube to ensure that the quartz tube enters the subsequent station in a stable posture; the detection device is the quality inspection end, with a built-in photoelectric sensor for real-time detection of the outer diameter, surface quality and travel length of the quartz tube; the first electric slide 4 is used to drive the traction component 6 to move back and forth along the guide rail 10, and the second electric slide 5 is used to drive the second push plate 907 to move, so that the quartz tube 3 pushes the bearing ring 8 to reset after cutting. The traction component is used to clamp the quartz tube 3 and pull it to move forward continuously in the horizontal direction. The bearing rod 7 is used to provide sliding support for the bearing ring 8, and a magnetic block is provided at the end near the detection device 2 to stabilize the reset position of the bearing ring 8.

[0024] The transmission assembly includes a connecting rod 901 and a first sliding frame 904. The connecting rod 901 is located on one side of the outer wall of the bearing ring 8. The other end of the connecting rod 901 is connected to a telescopic rod 902. The adjusting end of the telescopic rod 902 is connected to a U-shaped insert rod 903. The first sliding frame 904 is mounted on the guide rail 10. A bracket 908 is installed on the first sliding frame 904. The other end of the bracket 908 is connected to the traction assembly 6. A slot 905 is provided inside the first sliding frame 904.

[0025] Specifically, based on the required cutting length of the quartz tube 3, the axial position of the U-shaped insertion rod 903 can be changed by adjusting the extension length of the telescopic rod 902, thereby controlling the starting position of the bearing ring 8 when inserting it into the generator, achieving switching between different cutting lengths. During operation, the first electric slide table 4 drives the traction component 6 to move continuously, causing the traction component 6 to continuously clamp and pull the quartz tube 3 to move, which in turn drives the first sliding frame 904 to slide synchronously along the guide rail 10 via the bracket 908. (See attached instruction manual) Figure 4It is known that a third pressure sensor is provided on the inner side of the U-shaped insertion rod 903. When the U-shaped insertion rod 903 extends with the telescopic rod 902 and is inserted into the slot 905, the third pressure sensor detects the insertion pressure signal and triggers the control terminal, which then controls the cutting assembly to start the cutting program. During the cutting process, the U-shaped insertion rod 903 is locked to the first sliding frame 904 through the slot 905. Then, the bearing ring 8 can be pulled along the bearing rod 7 by the connecting rod 901 and the telescopic rod 902 to achieve the follow-up cutting effect. This ensures that the traction assembly 6 remains in operation throughout the cutting process, continuously clamping and pulling the quartz tube 3 forward without stopping and waiting, thus achieving online continuous cutting of the quartz tube.

[0026] Furthermore, the cutting assembly includes a rotating ring 801 and a drive motor 804. The rotating ring 801 is rotatably disposed inside the bearing ring 8. The drive motor 804 is installed on one side of the outer wall of the bearing ring 8. A gear ring 802 is installed on the outer peripheral wall of the rotating ring 801. The output shaft of the drive motor 804 is provided with a drive gear 803 that meshes with the gear ring 802. A cutting device 808 is provided on the inner side wall of the rotating ring 801.

[0027] Specifically, when the drive motor 804 starts, its output shaft drives the drive gear 803 to rotate. The drive gear 803 drives the gear ring 802 to rotate through meshing transmission, which in turn drives the rotating ring 801 to rotate around its axis inside the bearing ring 8. This causes the rotating ring 801 to drive the cutting device 808 to rotate. The cutting device 808 is a conventional cutting device, consisting of components such as a distance control device and a cutting head. During cutting, the distance control device pushes the cutting head close to the outer wall of the quartz tube 3, and then the drive device that controls the cutting head drives the cutting head to rotate, making circumferential cuts on the outer wall of the quartz tube 3, thus cutting the quartz tube 3.

[0028] Furthermore, the cutting assembly also includes multiple sets of first electric actuators 805 and multiple sets of second electric actuators 806. The multiple sets of first electric actuators 805 and second electric actuators 806 are correspondingly arranged around both ends of the bearing ring 8. The moving ends of the first electric actuators 805 and the second electric actuators 806 extend into the interior of the bearing ring 8 and are connected to clamping plates 807.

[0029] Specifically, each clamping plate 807 has an arc-shaped concave surface on its inner side. The radius of curvature of the arc-shaped concave surface is adapted to the outer diameter of the quartz tube 3 to increase the contact area between the clamping plate 807 and the outer wall of the quartz tube 3 and reduce the contact pressure. At the same time, a flexible buffer pad layer, such as high-temperature resistant polyurethane or graphite pad, is also embedded in the arc-shaped concave surface of the clamping plate 807. In addition, the first electric push rod 805 is used to clamp the quartz tube 3 segment connected to the traction component 6 during cutting to prevent the finished segment from shaking or sagging due to loss of constraint at the moment of cutting. The second electric push rod 806 is used to clamp another segment of the quartz tube 3, so that during the cutting process, the subsequent segment to be cut can be pulled by pulling the bearing ring 8. At the same time, the first electric push rod 805 and the second electric push rod 806 clamp the areas on both sides of the cutting point of the quartz tube 3 to improve the cutting stability and cutting quality.

[0030] Furthermore, the traction assembly 6 includes a storage tube 601, which is installed at one end of the bracket 908. A third electric push rod 602 and a limiting plate 604 are respectively installed at both ends of the storage tube 601. A pull tube 603 is slidably connected inside the limiting plate 604, and the moving end of the third electric push rod 602 extends into the storage tube 601 and connects to one end of the pull tube 603. An annular groove 605 is provided on the edge of one end of the limiting plate 604, and a first pressure sensor is provided inside the annular groove 605.

[0031] Specifically, the drive motor of the first electric slide 4 is a variable speed motor. When the quartz tube 3 is pulled, the first electric slide 4 drives the receiving cylinder 601 to move quickly toward the end of the quartz tube 3 to be cut at a stroke greater than the stretching speed, shortening the idle stroke time. The annular groove 605 is also equipped with a laser rangefinder. When the receiving cylinder 601 moves to the end of the quartz tube 3 to be cut, the laser rangefinder monitors the distance between the receiving cylinder 601 and the end of the quartz tube 3 in real time and feeds it back to the control terminal. The control terminal controls the first electric slide 4 to decelerate according to the distance signal, so that the receiving cylinder 601 slowly approaches the cutting end of the quartz tube 3 until the cutting end contacts the first pressure sensor set at the front end of the receiving cylinder 601. The first pressure sensor triggers a signal to the control terminal, and the control terminal controls the third electric push rod 602 to start, pushing the pull cylinder 603 to extend axially into the interior of the quartz tube 3 to support the inner wall of one end of the quartz tube 3.

[0032] Furthermore, the traction assembly 6 also includes a support rod 606 and an inlet / outlet groove 609. The support rod 606 is located at the center of one end inside the pull tube 603. One end of the support rod 606 is connected to a mounting plate 607. Multiple sets of guide grooves 608 are formed around the mounting plate 607. A retaining plate 610 is slidably connected inside the guide groove 608. The inlet / outlet groove 609 is formed around the inside of the pull tube 603.

[0033] Furthermore, the traction assembly 6 also includes a fourth electric push rod 611 and an anti-slip pad 613. The fourth electric push rod 611 is located at the axis of one end inside the pull tube 603 away from the support rod 606. The moving end of the fourth electric push rod 611 is connected to the push plate 614. Multiple sets of connecting rods 612 are arranged around the push plate 614. The other end of the connecting rod 612 is connected to the card plate 610.

[0034] Furthermore, the outer edge area of ​​the card plate 610 is provided with an anti-slip pad 613, and the middle area of ​​the outer side of the card plate 610 is provided with a second pressure sensor.

[0035] Specifically, after the pull cylinder 603 extends axially into the quartz tube 3, the control terminal immediately controls the fourth electric actuator 611 to extend, pushing the push plate 614 to move axially along the pull cylinder 603 towards the support rod 606. When the push plate 614 moves, it pushes the corresponding locking plates 610 through multiple sets of connecting rods 612 arranged around it, so that each locking plate 610 slides outward along the corresponding guide groove 608 on the mounting plate 607 and passes through the inlet / outlet groove 609 circumferentially opened around the pull cylinder 603. The outer wall of the clamping plate 610 abuts against the inner wall of the quartz tube 3, and the anti-slip pad 613 embedded in the outer wall of the clamping plate 610 fits tightly against the inner wall of the quartz tube 3, achieving an internal support fixation of the inner wall of the end of the quartz tube 3. This continues until the second pressure sensor receives a pressure contact signal, at which point the control terminal stops the advancement of the fourth electric push rod 611 to avoid damage or breakage of the inner wall of the quartz tube 3 due to excessive tension. The control terminal then controls the first electric slide 4 to drive the traction component 6 at a uniform speed at the initial speed of stretching the quartz tube 3. The movement provides a traction basis for subsequent follow-up cutting. After the U-shaped insert rod 903 extends with the telescopic rod 902 and inserts into the slot 905, and the cutting assembly completes the circumferential cutting of the quartz tube 3, the first electric push rod 805 and the second electric push rod 806 are controlled to reset and release the clamping and fixing of the outer wall of the quartz tube 3. Then, the second electric slide table 5 drives the second push plate 907 to push the first push plate 906 to move closer to the detection device 2, so that the entire bearing ring 8 slides and resets to the initial position along the bearing rod 7. At this time, one end of the quartz tube 3 of the cutting section is separated from the inside of the bearing ring 8. At the same time, the fourth electric push rod 611 is controlled to retract, which can release the fixing of the multiple clamping plates 610 to the inner wall of the quartz tube 3. Then, the third electric push rod 602 is controlled to retract, which can drive the pull cylinder 603 to completely retract into the storage cylinder 601, so that the finished section of the quartz tube 3 after cutting is completely freed from the constraint of the traction assembly 6 and the bearing ring 8 and is in a suspended state, so that it can be received by the subsequent unloading mechanism.

[0036] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 8The material handling assembly includes a second sliding frame 1101, which is slidably mounted on the guide rail 10. A sleeve 1102 is installed on the second sliding frame 1101. A sleeve rod 1103 slides through the inside of the sleeve 1102. A third spring 1104 is provided between the sleeve rod 1103 and the inside of the sleeve 1102. One end of the sleeve rod 1103 is connected to a receiving frame 1107. A discharge plate 1109 is connected to the edge of the receiving frame 1107. An inclined surface 1108 is provided on the receiving frame 1107.

[0037] Furthermore, the material handling assembly also includes a first inclined plate 1105 and a second inclined plate 1106. The first inclined plate 1105 is connected to one end of the sleeve rod 1103, and a limiting groove for the first inclined plate 1105 to slide up and down is provided on one side of the sleeve 1102. The second inclined plate 1106 is installed on the first sliding frame 904.

[0038] Furthermore, a conveying device 12 is placed on one side of the guide rail 10.

[0039] Specifically, when the traction assembly 6 moves the bearing ring 8, its second inclined plate 1106 moves along with the traction assembly 6. During this process, the inclined surface of the second inclined plate 1106 gradually contacts the bottom side of the first inclined plate 1105, pushing the first inclined plate 1105 up along the limiting groove of the sleeve 1102, thereby driving the sleeve rod 1103 to slide upward against the elastic force of the third spring 1104, so that the receiving frame 1107 rises to a high position and contacts the finished section of the quartz tube 3 to receive it. After the quartz tube 3 falls onto the receiving frame 1107, it rolls down its inclined surface 1108 to the discharge point. The quartz tube 3 is guided by the discharge plate 1109 and falls into the conveying device 12 located on one side of the guide rail 10. The conveying device 12 transports the finished quartz tube 3 to the next process. When the traction component 6 drives the first sliding frame 904 to move in the reverse reset direction, the second inclined plate 1106 moves backward, releasing the thrust on the first inclined plate 1105. The sleeve rod 1103 slides down along the sleeve 1102 under the elastic restoring force of the third spring 1104, driving the receiving frame 1107 to descend to a low position, completely clearing the travel channel of the quartz tube 3 and ensuring no positional interference with subsequent tubes.

[0040] Workflow: First, based on the required cutting length of the quartz tube 3, adjust the extension length of the telescopic rod 902 to change the axial position of the U-shaped insert rod 903, and determine the starting position of the insertion contact of the bearing ring 8. After startup, the variable speed motor of the first electric slide table 4 drives the traction assembly 6 to move quickly towards the end of the quartz tube 3 to be cut. The laser rangefinder in the annular groove 605 monitors the distance in real time and provides feedback to control deceleration, so that the storage cylinder 601 slowly approaches until the end of the quartz tube 3 touches the first pressure sensor, triggering the third electric push rod 602 to push the pull cylinder 603 into the interior of the quartz tube 3. Subsequently, the fourth electric push rod 611 extends to push the push plate 614, which drives multiple sets of clamping plates 610 to slide radially out along the guide groove 608 via the connecting rod 612, and then passes through the anti-slip pad 613 and the quartz tube. The inner wall of tube 3 is tightly fitted to achieve internal support fixation. After the second pressure sensor feeds back a pressure contact signal, the advancement stops. The first electric slide table 4 pulls the quartz tube 3 forward at an initial stretching speed. When the traction component 6 moves the first sliding frame 904 to the preset position via the bracket 908, the telescopic rod 902 pushes the U-shaped insert rod 903 to extend and insert into the slot 905. The third pressure sensor triggers a signal to confirm that the bearing ring 8 and the traction component 6 have established a rigid connection. Then, the first electric push rod 805 and the second electric push rod 806 extend simultaneously, clamping the tube walls on both sides of the cutting point of the quartz tube 3 through the clamping plate 807. At the same time, the drive motor 804 drives the rotating ring 801 to rotate via the drive gear 803 meshing with the gear ring 802, driving the cutting device 80. 8. The quartz tube 3 is circumferentially cut. During the cutting process, the traction component 6 maintains a constant speed and is locked by the U-shaped plug 903 and the slot 905, pulling the bearing ring 8 to slide synchronously along the bearing rod 7 to achieve follow-up cutting. After the cutting is completed, the first electric push rod 805 and the second electric push rod 806 are reset to release the external clamp. The second electric slide table 5 pushes the first push plate 906 through the second push plate 907 to make the bearing ring 8 slide and reset along the bearing rod 7. At the same time, the fourth electric push rod 611 retracts, driving the clamping plate 610 to slide inward along the guide groove 608 and retract into the pull cylinder 603 through the inlet and outlet groove 609, releasing the internal support fixation. The third electric push rod 602 retracts, making the pull cylinder 603 completely retract into the receiving cylinder 601. The cut finished section of the quartz tube 3 is completely The tube is released from its constraint and suspended in mid-air. Simultaneously, as the traction assembly 6 moves forward, the second inclined plate 1106 on the first sliding frame 904 moves forward, and its inclined surface pushes the first inclined plate 1105 to rise along the limiting groove of the sleeve 1102. This causes the sleeve rod 1103 to overcome the elastic force of the third spring 1104, causing the receiving frame 1107 to rise to a high position to receive the suspended finished quartz tube 3. The quartz tube 3 rolls down along the inclined surface 1108 to the discharge plate 1109 and is guided into the conveying equipment 12 for delivery. Finally, when the traction assembly 6 moves in the reverse direction to reset, the second inclined plate 1106 retracts, and the sleeve rod 1103, under the action of the third spring 1104, causes the receiving frame 1107 to descend to a low position, making way for the tube, thus completing a complete online follow-up cutting cycle.
