Description

Technical Field

[0001] The utility model belongs to the technical field of production equipment for optical fiber preform rods, and in particular relates to a large-size quartz rod processing lathe with multiple process functions. Background Art

[0002] At present, according to different requirements of optical fiber products, there are many hot processing processes for large-size optical fiber preform rods in the existing technology, which require docking, taper pulling and rod twisting processes respectively. Each process needs to rely on processing lathes with different functions for processing, which leads to unfavorable situations such as many types of lathes in the workshop, crowded equipment, and poor logistics. At the same time, water, electricity and gas supply are also required to ensure the normal operation of the equipment. Crowded equipment will inevitably cause the water, electricity and gas supply pipelines to be messy and unreasonable. Moreover, each process is easy to interfere with each other during work, occupying public lifting and transportation equipment. Therefore, a lathe with multiple process functions is needed to reduce the number of equipment, reduce energy consumption, facilitate the reasonable layout of the workshop, and reduce the difficulty of equipment maintenance. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in view of the deficiencies of the prior art, a large-size quartz rod processing lathe with multiple process functions is provided, which has a compact structure, reasonable layout, multiple process functions and high working reliability.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A large-size quartz rod processing lathe with multiple process functions comprises a bed, a left headstock 3, a propane heating and insulation chamber 2, a propane combustion heating quartz chamber 1 and a right headstock 4; a sliding track is provided on the upper end surface of the bed, and the left headstock 3, the propane heating and insulation chamber 2, the propane combustion heating quartz chamber 1 and the right headstock 4 are sequentially clamped on the sliding track from left to right, and can move horizontally along the sliding track; a chuck 5 for clamping a quartz rod 6 to be processed is installed on both the left headstock 3 and the right headstock 4.

[0006] Preferably, the chucks 5 on the left headboard box 3 and the right headboard box 4 are both connected to corresponding drive motors.

[0007] Preferably, the chuck 5 is rotatably connected to the corresponding end surface of the headboard box, and the chuck 5 on the left headboard box 3 and the right headboard box 4 can be driven by a motor to rotate synchronously or asynchronously.

[0008] Preferably, the clamping size of the chuck 5 is adapted to the size of the quartz rod 6 to be processed.

[0009] Preferably, the bottoms of the left bedside box 3, the propane heating and insulation chamber 2, the propane combustion heating quartz chamber 1 and the right bedside box 4 are all provided with electric sliders, and are clamped on the sliding track through the electric sliders.

[0010] Preferably, the left bedside box 3 and the right bedside box 4 are symmetrically arranged on the sliding track.

[0011] Preferably, the middle parts of the propane heating and insulation chamber 2 and the propane combustion heating quartz chamber 1 are both provided with through holes matched with the size of the quartz rod 6 to be processed.

[0012] During docking, the quartz rod 6 to be docked is placed on the left and right head boxes 3 and 4 respectively, and the quartz rod 6 is clamped by the chuck 5 and rotated synchronously. During production, the high temperature generated by the combustion of the propane-heated quartz chamber 1 heats and melts the end face of the quartz rod 6, and the left and right head boxes 3 and 4 move relative to each other to squeeze the melted end face to complete the docking work. After the work is completed, the propane combustion is turned off, and the extruded and bonded area is placed in the propane-heated quartz chamber 1 for heat preservation and cooling to prevent internal stress caused by rapid cooling.

After the quartz rod is connected, the left and right head boxes 3 and 4 move in the opposite direction to stretch the quartz rod 6 into the required cone shape. One end of the formed cone is slowly cooled with the furnace temperature in the propane-heated quartz chamber 1, and the other end of the cone is kept warm in the propane-heated insulation chamber 2, and the propane flow rate of the propane-heated insulation chamber 2 is gradually reduced to achieve a slow cooling effect.

[0014] During the twisting operation, the two ends of the quartz rod 6 to be twisted are placed on the left and right head boxes 3 and 4 respectively, and the quartz rod 6 is clamped by the chuck 5 and rotated synchronously. During the twisting operation, only one quartz rod 6 is used. During production, the high temperature generated by the combustion of the propane combustion heating quartz chamber 1 melts the part of the quartz rod 6 that needs to be processed, and the chucks 5 of the left and right head boxes 3 and 4 rotate asynchronously under the control of the motor to twist the quartz rod 6. At the same time, the left and right head boxes 3 and 4 move relative to each other or in the opposite direction to stretch or extrude the twisted part. The twisted extrusion molding part is slowly cooled with the furnace temperature in the propane combustion heating quartz chamber 1, and the twisted stretching part is kept warm in the propane heating and insulation chamber 2, and the propane flow of the propane heating and insulation chamber 2 is gradually reduced to achieve the effect of slow cooling.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] It should be pointed out that, according to the needs of implementation, the various steps / components described in this application can be split into more steps / components, and two or more steps / components or partial operations of steps / components can be combined into new steps / components to achieve the purpose of the present utility model.

[0026] Embodiment 1: This embodiment provides a large-size quartz rod processing lathe with multiple process functions, such as Figures 1 to 4 As shown, it mainly includes a bed body, a left bedside box 3, a right bedside box 4, a propane combustion heating quartz chamber 1 and a propane heating and insulation chamber 2.

[0027] Wherein, the left bedside box, the right bedside box, the propane combustion heating quartz chamber, and the propane heating and insulation chamber are all installed on the bed body.

[0028] The left and right headboard boxes have the function of moving left and right, and the chucks of the left and right headboard boxes have the function of synchronous rotation and asynchronous rotation, thereby realizing the docking, taper pulling and twisting of quartz rods;

[0029] The propane combustion heating quartz chamber and the propane heating insulation chamber melt the large-sized quartz rods by propane combustion heating, and assist in completing the docking, taper and twisting of the quartz rods. At the same time, the residual heat of the propane combustion heating quartz chamber and the propane heating insulation chamber form an insulation area to prevent the quartz rods that have been deformed by heating from generating internal stress due to rapid cooling. Large internal stress can easily cause the quartz rods to break during the secondary heating process of the quartz rods.

[0030] Furthermore, when the quartz rods are docked, the quartz rods to be docked are placed on the left and right headboard boxes respectively and clamped with chucks. The left and right headboard boxes move toward each other, and the chucks of the two headboard boxes rotate synchronously. The propane combustion and heating quartz chamber melts the parts of the quartz rods that need to be heated at high temperature and then docks. The left and right headboard boxes continue to move to press the docking joints, and the chucks rotate synchronously to ensure uniform docking. The docking area is placed in the propane combustion and heating quartz chamber to use the insulation function of the quartz chamber and the residual temperature to slowly cool down to prevent internal stress.

[0031] Furthermore, when the quartz rod is tapering, the quartz rod to be taper is placed on the left and right headstocks respectively and clamped by chucks. The left and right headstocks move toward each other, and the chucks of the two headstocks rotate synchronously. The propane combustion and heating quartz chamber melts the part of the quartz rod to be heated at high temperature and then docks. Then, the left and right headstocks move in opposite directions to taper, and the two ends of the formed tapered area are placed in the propane combustion and heating quartz chamber and the propane heating and insulation chamber respectively to slowly cool down, thereby preventing the tapered area from drastically cooling down and generating internal stress.

[0032] Furthermore, when the quartz rod is twisted, the two ends of the quartz rod to be twisted are placed on the left and right head boxes respectively and clamped by chucks. After the propane combustion heats the quartz chamber to melt the part of the quartz rod to be heated at high temperature, the left and right head box chucks rotate asynchronously to twist the quartz rod. At the same time, the head box is controlled to move left and right to stretch or extrude the twisted area, and the forming area enters the propane heating and insulation chamber to prevent internal stress. Repeat the above steps to twist and form the entire quartz rod in sections.

[0033] Embodiment 2: This embodiment provides a large-size quartz rod processing lathe with multiple process functions, and the specific working principle is as follows:

[0034] During docking, the quartz rod 6 to be docked is placed on the left and right head boxes 3 and 4 respectively, and the quartz rod 6 is clamped by the chuck 5 and rotated synchronously. During production, the high temperature generated by the combustion of the propane-heated quartz chamber 1 heats and melts the end face of the quartz rod 6, and the left and right head boxes 3 and 4 move relative to each other to squeeze the melted end face to complete the docking work. After the work is completed, the propane combustion is turned off, and the extruded and bonded area is placed in the propane-heated quartz chamber 1 for heat preservation and cooling to prevent internal stress caused by rapid cooling.

[0035] When the taper is being pulled, the quartz rod 6 to be tapered is placed on the left and right head boxes 3 and 4 respectively, and the quartz rod 6 is clamped by the chuck 5 and rotated synchronously. During production, the high temperature generated by the combustion of the propane-heated quartz chamber 1 heats and melts the end face of the quartz rod 6, and the left and right head boxes 3 and 4 move relative to each other to squeeze the melted end face. After the quartz rod is connected, the left and right head boxes 3 and 4 move in the opposite direction to stretch the quartz rod 6 into the required cone shape. One end of the formed cone is slowly cooled with the furnace temperature in the propane-heated quartz chamber 1, and the other end of the cone is kept warm in the propane-heated insulation chamber 2, and the propane flow rate of the propane-heated insulation chamber 2 is gradually reduced to achieve a slow cooling effect.

[0036] During the twisting operation, the two ends of the quartz rod 6 to be twisted are placed on the left and right head boxes 3 and 4 respectively, and the quartz rod 6 is clamped by the chuck 5 and rotated synchronously. During the twisting operation, only one quartz rod 6 is used. During production, the high temperature generated by the combustion of the propane combustion heating quartz chamber 1 melts the part of the quartz rod 6 that needs to be processed, and the chucks 5 of the left and right head boxes 3 and 4 rotate asynchronously under the control of the motor to twist the quartz rod 6. At the same time, the left and right head boxes 3 and 4 move relative to each other or in the opposite direction to stretch or extrude the twisted part. The twisted extrusion molding part is slowly cooled with the furnace temperature in the propane combustion heating quartz chamber 1, and the twisted stretching part is kept warm in the propane heating and insulation chamber 2, and the propane flow of the propane heating and insulation chamber 2 is gradually reduced to achieve the effect of slow cooling.
