Description

TECHNICAL FIELD

[0001] The application relates to a continuous cutting device and a cutting method of a quartz rod and belongs to the technical field of quartz glass rod production. BACKGROUND

[0002] Quartz glass material is widely used in the fields of semiconductors, precision optics, information transmission and the like due to its excellent optical performance, heat shock resistance, extremely low thermal expansion coefficient and electrical conductivity. The quartz fiber drawn from the quartz glass rod not only has heat resistance, corrosion resistance and softness, but also has high strength retention rate, size stability, heat shock resistance, chemical stability, light transmission and electrical insulation in a high-temperature state. The quartz fiber is often used in optical fibers, aerospace, high-speed rail and the like aerospace, military industry and semiconductor industry. The quartz glass rod is a basic material for manufacturing the quartz fiber.

[0003] At present, the quartz glass rod is mainly processed by repeatedly hot reforming a quartz glass ingot into a quartz glass rod with a certain diameter and then cutting the quartz glass rod into a fixed length by hand in a subsequent station. Since the specifications of quartz fiber drawing machines are different, the diameter of the quartz glass rod is usually required to be controlled within 1-10 mm with an error of ±0.05 mm, and the length is required to be controlled within 1500-1800 mm. In the preparation process of the quartz glass rod, the diameter and temperature affect the quartz glass rod, and the quartz glass rod is prone to breakage when being cut into a fixed length by hand in the subsequent station, which cannot meet the fixed length requirement of the quartz glass. This result leads to inconsistent consumption speed of the quartz glass rod in the drawing process of the quartz fiber, and the quartz fiber drawing machine needs to be stopped and the rod needs to be replaced from time to time, thereby leading to low quartz fiber drawing efficiency. On the other hand, the hot-reformed quartz glass rod needs to be transported to the subsequent station for cutting into a fixed length by hand. Since the quartz glass rod is high in brittleness, the quartz glass rod is prone to breakage due to external vibration in the transportation process and jumping of the quartz glass rod in the cutting process. The result not only affects the fixed length production of the quartz glass rod, but also leads to an increase in production cost and affects the subsequent quartz fiber drawing efficiency. Therefore, it is necessary to improve the quartz glass rod. SUMMARY

[0004] The application aims to provide a continuous cutting device and a cutting method of a quartz rod which can meet the fixed length cutting requirement of the quartz glass rod and effectively avoid the breakage of the quartz glass rod caused by jumping of the quartz glass rod in the cutting process.

[0018] 1) Start the lifting motor, and drive the positioning sliding plate 2 to move to the set position along the sliding rail by the lifting motor according to the product length requirement, and complete the preparation work;

[0019] 2) The quartz glass rod which has been heated and reshaped in the conventional pre-process and cooled vertically goes down through the guide pipe into the upper clamping piece and the lower clamping piece, and continues to extend downward to contact the mounting base plate, and the quartz glass rod does not go down any more after contacting the mounting base plate,

[0036] The continuous cutting device of the quartz rod is composed of a mounting base plate 1, a positioning sliding plate 2, a cutting mechanism and a push rod mechanism. The mounting base plate 1 is symmetrically provided with sliding rails 3, the positioning sliding plate 2 is slidingly installed on the sliding rails 3, the ends of the sliding rails 3 corresponding to the positioning sliding plate 2 are fixed with lifting motors 5 through the mounting base plate 1 and a mounting bottom plate 4, and the lifting motors 5 are connected with the positioning sliding plate 2 through lifting lead screws 6, so that the positioning sliding plate 2 is driven to move up and down along the sliding rails 3 during work. The cutting mechanism is slidingly installed on the positioning sliding plate 2 through symmetrically arranged transverse sliding grooves 7.

[0037] The cutting mechanism is composed of a cutting sliding block 8, a cutting motor 9, a cutting knife 10 and a mounting block 11. The cutting sliding block 8 is provided with an assembly recess on one side, the cutting motor 9 is fixed in the assembly recess, the cutting knife 10 in the shape of a disc is mounted in the assembly recess on one side of the cutting motor 9 through the mounting block 11 and an assembly shaft, and the cutting motor 9 is connected with the assembly shaft through a transmission belt 12. A lead screw motor 13 is fixed on the positioning sliding plate 2 between the transverse sliding grooves 7 on one side of the cutting sliding block 8, and the lead screw motor 13 is connected with the cutting sliding block 8 through a transmission lead screw.

[0038] The cutting sliding block 8 is a rectangular body, and the transverse sliding grooves 7 are trapezoidal sliding grooves. Trapezoidal sliding blocks are arranged on the back of the cutting sliding block 8 corresponding to the transverse sliding grooves 7, and the cutting sliding block 8 is slidingly installed on the positioning sliding plate 2 through the cooperation of the trapezoidal sliding blocks and the transverse sliding grooves 7.

[0039] An upper clamping piece 14 and a lower clamping piece 15 are installed on the cutting sliding block 8 on one side of the cutting mechanism in an upper and lower interval manner through the positioning sliding plate 2, upper locking plates 16 and lower locking plates 17 are installed on the end faces above and below the assembly recess of the cutting sliding block 8 of the cutting mechanism corresponding to the upper clamping piece 14 and the lower clamping piece 15, and the length of the upper locking plates 16 is greater than the length of the lower locking plates 17. The upper locking plates 16 and the lower locking plates 17 are intermittently slidingly connected with the upper clamping piece 14 and the lower clamping piece 15.

[0040] The mounting base plate 1 is in the shape of a "7" in cross section. Guiding pipes 18 are arranged on the top of the mounting base plate 1 corresponding to the upper clamping piece 14 and the lower clamping piece 15, and the upper clamping piece 14, the lower clamping piece 15 and the guiding pipes 18 are coaxially arranged to ensure that the quartz glass rod to be cut can accurately enter the upper clamping piece 14 and the lower clamping piece 15 during work.

[0041] The upper clamping piece 14 and the lower clamping piece 15 of the continuous cutting device are respectively composed of a mounting ring 19, a clamping block and a clamping gasket 20, and the mounting ring 19 is arranged in an up-down manner; the mounting ring 19 is a C-shaped ring, and radially symmetrical assembly holes are arranged on the mounting ring body on both sides of the opening of the mounting ring 19; the clamping block is movably mounted on the mounting ring through the assembly holes. The clamping block is cylindrical and is composed of a left clamping block 21 and a right clamping block 22 which are semicircular in cross section; a slide rod 23 is arranged on the outer circumferences of the left clamping block 21 and the right clamping block 22 corresponding to the assembly holes; the left clamping block 21 and the right clamping block 22 are slidably mounted on the mounting ring 19 through the cooperation of the slide rods and the assembly holes. A return spring is arranged on the slide rod 23 in the assembly hole, and a clamping gasket 20 is arranged on the corresponding end faces of the left clamping block 21 and the right clamping block 22, and a clamping groove 24 is arranged on the end face of the clamping gasket 20. An installation seat 25 is arranged on one side of the mounting ring 19; and the mounting ring 19 is fixedly connected with the positioning slide plate 2 through the installation seat 25. During work, the left clamping block 21 and the right clamping block 22 can be folded towards each other under the action of an external force, and the quartz glass rod can be clamped through the clamping groove 24 on the end face of the clamping gasket 20; after the external force is removed, the clamping gaskets 20 on the left clamping block 21 and the right clamping block 22 can be separated from each other under the action of the return spring. The clamping gasket 20 is made of elastic material and has a certain variable range under the extrusion of the external force, so as to achieve the purpose of clamping and stabilizing the quartz glass rod 27. By replacing the clamping gaskets 20 with different sizes of clamping grooves 24, the clamping requirements of quartz glass rods 27 of different diameters can be met.

[0042] The upper locking plate 16 and the lower locking plate 17 of the continuous cutting device are respectively rectangular plate-shaped bodies; and the upper locking plate 16 and the lower locking plate 17 are respectively provided with open locking sliding grooves 26, and the end ports of the locking sliding grooves 26 are in a horn shape. The upper locking plate 16 and the lower locking plate 17 are respectively slidably connected with the upper clamping piece 14 and the lower clamping piece 15 through the locking sliding grooves 26.

[0043] The positioning slide plate 2 movably mounts a push rod mechanism through a pin 28, the push rod mechanism is composed of a push rod 29 and a lever 30, the push rod 29 is movably mounted on the positioning slide plate 2 through the pin 28, and the cutting sliding block 8 is symmetrically provided with the lever 30; the push rod 29 is L-shaped, one end of the push rod 29 extends to above the lever 30 through the levers 30, and the push rod 29 extending to above the lever 30 is slidably connected with the lever 30. The other end of the push rod 29 movably mounts a push plate 31 through the pin 28.

[0044] The installation base plate 4 of the continuous cutting device is the installation base of the lifting motor 5 and the fixed-length base plate of the quartz glass rod. During operation, the installation base plate 4 is used as a reference; first, the lifting motor 5 is started, and the positioning slide plate 2 is driven by the lifting motor 5 to move along the slide rail 3 to the set position according to the product length requirement, and the preparation work is completed. In the conventional pre-process link above the continuous cutting device, the quartz glass rod that has completed hot reforming and cooling vertically descends through the guide pipe 18 into the continuous cutting device and extends downward. The downward extending quartz glass rod is inserted into the locking sliding groove 26 of the upper clamping part 14 and the lower clamping part 15 in turn, and continues to extend downward to contact the installation base plate 4. After contacting the installation base plate 4, the quartz glass rod no longer descends, at this time, the lead screw motor 13 and the cutting motor 9 are started; the lead screw motor 13 drives the cutting sliding block 8 to move forward along the transverse sliding groove 7 through the transmission lead screw, at the same time, the cutting motor 9 drives the assembly shaft to rotate through the transmission belt 12, thereby driving the cutting knife 10 on the assembly shaft to rotate.

[0045] Because the length of the upper locking plate 16 is greater than the length of the lower locking plate 17; during the process of the lead screw motor 13 driving the cutting sliding block 8 to move forward along the transverse sliding groove 7, the upper locking plate 16 first contacts the upper clamping part 14, that is, the part of the upper clamping part 14 between the installation rings 19 enters the locking sliding groove 26 of the upper locking plate 16. Under the action of the trumpet-shaped port of the locking sliding groove 26, at this time, the forward movement of the upper locking plate 16 gradually shrinks the trumpet-shaped port of the locking sliding groove 26, forming radial pressure on the left clamping block 21 and the right clamping block 22 of the upper clamping part 14, forcing the left clamping block 21 and the right clamping block 22 to close to each other, thereby clamping the quartz glass rod through the clamping groove 24 on the end face of the clamping gasket 20. The radial pressure of the trumpet-shaped port of the locking sliding groove 26 on the upper clamping part 14 makes the left clamping block 21 and the right clamping block 22 close to each other, and the state is maintained through the parallel groove part of the locking sliding groove 26 at the rear end of the trumpet-shaped port.

[0046] The upper clamping member 14 continues to slide to the bottom of the parallel groove part of the locking sliding groove 26 during the process that the lead screw motor 13 drives the cutting sliding block 8 to continue to move forward along the transverse sliding groove 7. The lower locking plate 17 completes the locking of the lower clamping member 15 as the cutting sliding block 8 continues to move forward along the transverse sliding groove 7. At this time, the locking state of the lower clamping member 15 is maintained through the parallel groove part of the locking sliding groove 26. The cutting knife 10 contacts the quartz glass rod 27 during the sliding of the clamping member in the locking sliding groove 26, and the cutting of the quartz glass rod 27 is completed during the process that the cutting sliding block 8 continues to move forward along the transverse sliding groove 7. The upper clamping member 14 and the lower clamping member 15 not only serve a stable purpose for the quartz glass rod 27 through the clamping of the clamping gasket 20 on the left clamping block 21 and the right clamping block 22, but also disperse and eliminate the vibration force generated by the cutting knife 10 during the cutting of the quartz glass rod 27, so as to avoid the fracture of the quartz glass rod 27 caused by the jumping of the quartz glass rod 27 during the existing cutting process. Thus, the problem that the quartz glass rod 27 is easily broken due to the jumping during the existing cutting process is solved.

[0047] After the cutting of the quartz glass rod 27 is completed, the lead screw motor 13 drives the cutting sliding block 8 to retreat and reset along the transverse sliding groove 7. During this process, the locking state between the lower locking plate 17 and the lower clamping member 15 is released, and the clamping gasket 20 on the left clamping block 21 and the right clamping block 22 can be separated from each other under the action of the reset spring. At the same time, the push rod 29 is installed on the positioning sliding plate 2 through the pin 28, the push rod 30 is symmetrically arranged on the cutting sliding block 8, and the push rod 29 and the push rod 30 are in sliding connection. During the process that the cutting sliding block 8 retreats and resets along the transverse sliding groove 7, the push rod 29 is driven by the push rod 30 to rotate counterclockwise around the pin 28 as the axis. During the counterclockwise rotation of the push rod 29, the truncated quartz glass rod 27 is pushed out of the lower clamping member 15 by the push plate 31 at the end of the push rod 29, so as to prepare for the subsequent work cycle.

[0048] The truncated quartz glass rod 27 is pushed out of the lower clamping member 15 at the same time that the locking state of the upper clamping member 14 is released. The quartz glass rod 27 to be cut in the upper clamping member 14 extends downward and inserts into the lower clamping member 15 and continues to extend downward to contact the installation bottom plate 4, and the next work cycle begins.
