Description

Technical Field

[0001] This utility model relates to the field of quartz tube welding and processing, and more specifically, to a welding support device for deep processing of quartz tubes. Background Technology

[0002] "Deep processing" generally refers to further processing of raw materials or semi-finished products to produce more complex or higher-value products. For the deep processing of quartz tubes through welding, support devices are needed to improve the stability of the quartz tube in the welding position.

[0003] Before welding quartz tubes, the welding area needs to be preheated to reduce thermal stress and improve welding quality. However, the existing support device and preheating device are separate designs, and the preheating device itself does not have a support function. Therefore, an additional support device needs to be designed during the heating process to improve the stability of the quartz tube end.

[0004] The heating effect of the preheating device causes excessive local temperature difference in the quartz tube, resulting in stress concentration in some sections of the quartz tube, which affects subsequent welding. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a welding support device for deep processing of quartz tubes. The technical problem to be solved by this utility model is: how to integrate the support and preheating functions and reduce the impact of excessive temperature difference caused by local heating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding support device for deep processing of quartz tubes, comprising a gripper mechanism for clamping the quartz tube; a heating mechanism comprising a support ring and a spiral resistance wire, the spiral resistance wire being electrically connected to the mains power supply and fixed to the support ring, the quartz tube passing through the support ring and the spiral resistance wire; an air guiding mechanism comprising a housing and an air outlet, the air outlet being provided on the side of the housing and connected to a fan, the airflow blowing out from the air outlet flowing in a direction that conforms to the surface of the quartz tube and the spiral resistance wire being located in the airflow path; and a support mechanism for supporting the heating mechanism and the air guiding mechanism.

[0007] In a preferred embodiment, the housing is provided with an opening and closing door panel, one end of which is rotatably connected to the inner wall of the air outlet, and the other end rests on the outer side of the inner end face of the air outlet.

[0008] In a preferred embodiment, there is a damped rotatable connection between the door panel and the air outlet.

[0009] In a preferred embodiment, the door panel is magnetic, and the corresponding support ring is also magnetic, with magnetic repulsion between the door panel and the corresponding support ring.

[0010] In a preferred embodiment, a magnetic sheet is bonded to the side of the door panel facing outwards, and a magnetic sheet is bonded to the support ring; the two magnetic sheets have the same magnetism.

[0011] In a preferred embodiment, the housing is connected to a fan via a duct, and opening / closing doors are located on both sides of the duct.

[0012] In a preferred embodiment, the inner diameter of the spiral resistance wire is larger than the inner diameter of the support ring, which is used to support the corresponding end of the quartz tube.

[0013] In a preferred embodiment, the support mechanism includes a first support rod, a second support rod, and a base. The second support rod is fixed to a corresponding support ring or housing. The first support rod and the second support rod are mutually limited and slidably connected.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This application mainly utilizes the supportable and preheatable characteristics of the heating mechanism to heat the end of the quartz tube inserted in the heating mechanism. By utilizing the air guiding characteristics of the air guiding mechanism, the airflow blows the heat emitted by the heating mechanism towards the rear end of the quartz tube, thereby reducing the excessive local temperature difference in the quartz tube and reducing the impact of stress on the welding process.

Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure.

[0024] Example

[0025] like Figures 1-4 A welding support device for deep processing of quartz tubes includes a gripper mechanism 1, a heating mechanism 2, an air guide mechanism 3, and a support mechanism 4. The gripper mechanism 1 is used to clamp the middle sections of two quartz tubes to be welded. The heating mechanism 2 is used to provide support at the end of the quartz tube to be welded while preheating the end. The air guide mechanism 3 is used to blow air onto the heating mechanism 2 to gradually transfer the heat emitted by the heating mechanism 2 to the rear end of the quartz tube, thereby reducing the local temperature difference and stress on the quartz tube. The support mechanism 4 is used to support the heating mechanism 2 and the air guide mechanism 3.

[0026] Specifically, the gripper mechanism 1 includes a guide rail 11, a slide 12, and gripping claws 13. The guide rail 11 is fixed to a wall or frame and is set perpendicular to the ground. The slide 12 is slidably connected to the guide rail 11. A pair of gripping claws 13 are rotatably connected to the slide 12. The user can use a cylinder, slide table, or other equipment to drive the slide 12 to slide relative to the guide rail 11. The gripping claws 13 can move closer to or further away from each other under the drive of a motor or linkage mechanism. The specific structures of the cylinder, motor, etc. are not shown in the figure because the structure of the gripper mechanism 1 is existing technology and is therefore omitted here.

[0027] The heating mechanism 2 includes a support ring 21 and a spiral resistance wire 22. The spiral resistance wire 22 is fixed on the support ring 21 and is electrically connected to a wire embedded inside the support ring 21. The wire in the support ring 21 is used to connect to the mains power. When the power is turned on, the spiral resistance wire 22 is energized and heats up, heating the end of the quartz tube that passes through the support ring 21 and the spiral resistance wire 22. At the same time, the support ring 21 can also support the quartz tube. The combination of the gripper mechanism 1 and the heating mechanism 2 can improve the stability of the quartz tube during preheating.

[0028] Preferably, the inner diameter of the spiral resistance wire 22 is larger than the inner diameter of the support ring 21 to avoid direct contact between the spiral resistance wire 22 and the quartz tube resting on the support ring 21.

[0029] Furthermore, there are two heating mechanisms 2, which are used to preheat the ends of the two quartz tubes that need to be welded, and a wind guide mechanism 3 is arranged between the two heating mechanisms 2.

[0030] The air guiding mechanism 3 includes a housing 31, a cover plate 32, an air outlet 33, and a duct 34. The axes of the housing 31 and the support ring 21 are collinear. The housing 31 and the cover plate 32 are detachably connected by a snap-fit ​​structure. Several air outlets 33 are provided on the cover plate 32. The housing 31 is a hollow structure. The duct 34 is used to connect the ventilator, the cavity of the housing 31, and the air outlet 33. Each air outlet 33 is rotatably connected to an opening and closing door plate 35. One end of the opening and closing door plate 35 is embedded and rotatably connected to the inner wall of the air outlet 33, and the other end rests on the outer side of the inner end face of the air outlet 33.

[0031] In one embodiment of this invention, the opening and closing door panel 35 and the cover plate 32 are connected by a damped rotation. At the beginning of use, after the opening and closing door panel 35 is rotated to the designated position, the cover plate 32 is closed onto the housing 31. A ventilator is then connected, and the ventilator inputs airflow from the duct 34 and outputs airflow from the opening of the opening and closing door panel 35 and the air outlet 33. The output airflow moves along the periphery of the quartz tube and carries the heat emitted by the spiral resistance wire 22 to the rear end of the quartz tube away from the welding end, thereby reducing the probability of stress deformation caused by excessive local temperature gradient in the quartz tube due to local heating of the spiral resistance wire 22.

[0032] In another embodiment of this invention, the opening and closing door panel 35 is magnetic, and the support ring 21 is also magnetic. The two magnetic elements repel each other. When the air guide mechanism 3 and any support ring 21 are close, the opening and closing door panel 35 will open, allowing a larger airflow to be blown toward the spiral resistance wire 22 after being guided by the air outlet 33. The airflow carries more heat and blows past the rear end of the quartz tube, further accelerating the efficiency of reducing the temperature gradient.

[0033] The aforementioned magnetic properties can be achieved by attaching magnetic patches to the surfaces of both the opening / closing door panel 35 and the support ring 21, or by making the opening / closing door panel 35 and the support ring 21 themselves from magnetic materials. No specific limitations are made here.

[0034] It should also be noted that the preheating temperature range of the quartz tube is 200-400℃, and iron, cobalt, and nickel can all be used as magnets.

[0035] The support mechanism 4 includes a first support rod 41, a second support rod 42, and a base 43. The first support rod 41 and the second support rod 42 are slidably connected. The second support rod 42 is used to be fixedly connected to the corresponding housing 31 or support ring 21. The second support rod 42 is slidably connected to the first support rod 41. The first support rod 41 is slidably connected to the base 43. The base 43 is placed on the factory ground.

[0036] Preferably, the support rod 41 and the support rod 42 are limited by a pin limiting member. Specifically, the support rod 41 and the support rod 42 are provided with several pin holes. By inserting a pin into the corresponding pin hole, the support rod 41 and the support rod 42 can be fixed.

[0037] Preferably, damping sheets are adhered between the contact surfaces of support rod 41 and support rod 42. After the positions of support rod 41 and support rod 42 are manually adjusted, their positions can remain stable without human interference, thereby keeping the position of the supported quartz tube unchanged.

[0038] In summary, this application mainly utilizes the supportable and preheatable characteristics of the heating mechanism 2 to heat the end of the quartz tube inserted in the heating mechanism 2. The air guiding characteristics of the air guiding mechanism 3 are used to blow the heat emitted by the heating mechanism 2 towards the rear end of the quartz tube, thereby reducing the excessive local temperature difference of the quartz tube and reducing the impact of stress on the welding process. After that, the power supply to the heating mechanism 2 is turned off, the air guiding mechanism 3 is lowered, and the clamping mechanism 1 clamps the quartz tube and moves it in the heating mechanism 2. After aligning the ends of the two quartz tubes, welding can be carried out.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
