Description

Technical Field

[0001] This utility model relates to the field of glass tube processing technology, and in particular to a high-efficiency glass tube flange forming device. Background Technology

[0002] Glass tube flange forming equipment is a specialized mechanical device used to process the ends of glass tubes into flange connection structures. Through processes such as heating, mold forming, or machining, the ends of glass tubes are formed to meet flange connection standards, which is suitable for sealing connection needs in laboratory glassware, vacuum equipment, and chemical pipelines.

[0003] However, the clamping mechanism of traditional glass tube flange forming equipment is usually fixed, which makes it difficult to adapt to glass tubes of different specifications and reduces the overall versatility of the equipment. Secondly, the height of the heating mechanism on traditional equipment is fixed, which makes it difficult to adjust according to the specifications of the glass tube, and it is easy to cause uneven heating, which in turn leads to glass tube breakage or poor flange forming. In addition, the traditional equipment relies on manual handling of the forming mold during processing, and the position and force of the forming mold are difficult to control, which not only increases the burden of manual operation, but also easily leads to poor flange dimensional accuracy.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This invention, through the setting of a clamping assembly, uses a motor to drive the rotary table to rotate via a gear transmission system consisting of a rotating shaft, a gear, a rotating shaft, and a gear, enabling the glass tube to rotate stably and at a uniform speed. This creates favorable conditions for uniform heating of all parts of the glass tube flange and subsequent molding. Furthermore, the combined use of the telescopic cylinder, the clamping seat, and the guide rail enables multi-directional, stable, and reliable clamping of the glass tube. The guide rail provides precise guidance for the clamping seat, ensuring smooth movement and accurate positioning of the clamping seat, effectively preventing the glass tube from shaking or shifting during processing and ensuring processing accuracy.

[0013] This invention features a heating component. The telescopic cylinder 2, via a telescopic rod, allows for flexible adjustment of the height of the arc-shaped mounting bracket 1 and the flamethrower. This enables precise control of the flamethrower height according to different glass tube specifications, ensuring uniform heating of the glass tube and effectively preventing problems such as glass tube breakage or poor flange forming caused by uneven heating. Furthermore, the unique design of the arc-shaped mounting bracket 1 conforms to the shape of the glass tube, and with multiple flamethrowers evenly distributed, it can provide all-round, dead-angle-free heating of the rotating glass tube, greatly improving heating efficiency, shortening heating time, and enhancing overall production efficiency.

[0014] This invention, through the setting of a mold assembly, uses a second motor to drive a lead screw to rotate, converting the rotational motion into the linear motion of a drive block. Combined with the guidance of a second guide rail, the vertical position of the forming mold can be precisely controlled. Simultaneously, the extension and retraction of the telescopic rod of a third telescopic cylinder allows the fixed plate and the forming mold to move horizontally, achieving precise contact and separation between the forming mold and the glass tube flange. This ensures accurate positioning of the forming mold during the forming process and guarantees the dimensional accuracy of the flange. Furthermore, the forming mold is positioned by a limit block cooperating with the upper limit groove of the fixed plate, and then fixed by a snap fastener, a fixed column, and a fixed cap. This ensures both the accuracy and stability of the forming mold installation and facilitates quick disassembly and replacement, meeting the forming requirements of different specifications of glass tube flanges and improving the equipment's versatility and production flexibility.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a high-efficiency glass tube flange forming equipment, which includes a workbench 1, a support frame 2 on one side of the workbench 1, a clamping assembly 3 on the support frame 2, a heating assembly 4 on the workbench 1 on one side of the support frame 2, and a mold assembly 5 on the side of the heating assembly 4 away from the clamping assembly 3.

[0023] The clamping assembly 3 includes a mounting box 31 mounted on the support frame 2. The mounting box 31 provides a mounting base for other components in the clamping assembly 3. A motor 32 is mounted on one side of the mounting box 31. A rotating shaft 33 is mounted on the transmission end of the motor 32. A gear 34 is fitted on the outside of the rotating shaft 33. The motor 32 provides rotational power to the rotating shaft 33 and the gear 34. A rotating shaft 35 is mounted inside the mounting box 31 on one side of the rotating shaft 33. A gear 36 is fitted on the outside of the rotating shaft 35. The gear 34 meshes with the gear 36. When the gear 34 rotates, it transmits power to the gear 36 through meshing, thereby driving the rotating shaft 35 to rotate. A protective plate 37 is mounted on the mounting box 31 to protect the internal components of the mounting box 31 from external environmental interference.

[0024] A second rotating shaft 35 passes through a protective plate 37. One end of the second rotating shaft 35 is equipped with a rotating platform 38 via a bearing seat. The second rotating shaft 35 drives the rotating platform 38 to rotate. The rotating platform 38 provides an installation base for the first telescopic cylinder 39 and the clamping seat 310. Telescopic cylinders 39 are arranged around the rotating platform 38. Each telescopic cylinder 39 has a clamping seat 310 at the top of its telescopic rod. The telescopic rods of the first telescopic cylinders 39 extend and retract, driving several clamping seats 310 to move closer to or away from the center, thereby clamping or releasing the glass tube. Guide rails 311 are arranged around the rotating platform 38. The clamping seats 310 are slidably mounted on the guide rails 311. The guide rails 311 provide guidance for the clamping seats 310, ensuring the stability of the clamping seats 310 during movement.

[0025] The heating assembly 4 includes a telescopic cylinder 41 mounted on the workbench 1. An arc-shaped mounting bracket 42 is mounted on the top of the telescopic rod of the telescopic cylinder 41. The telescopic rod of the telescopic cylinder 41 extends and retracts, driving the arc-shaped mounting bracket 42 to rise and fall, thus allowing the flamethrower 45 to adapt to glass tubes of different sizes and specifications. A pair of lifting guide columns 44 are symmetrically arranged at the bottom of the arc-shaped mounting bracket 42. Guide column sleeves 43 are provided on both sides of the workbench 1 corresponding to the positions of the lifting guide columns 44. The combined use of the lifting guide columns 44 and the guide column sleeves 43 ensures the stability of the arc-shaped mounting bracket 42 during its rise and fall. Several flamethrowers 45 are mounted on the arc-shaped mounting bracket 42. The flamethrowers 45 heat the rotating glass tube by spraying flames, bringing the glass tube to a formable temperature, preparing it for subsequent flange forming.

[0026] The mold assembly 5 includes a mounting bracket 51 mounted on the workbench 1. The mounting bracket 51 provides a mounting base for other components in the mold assembly 5. A fixing sleeve 52 is provided on the inner top surface of the mounting bracket 51, and a lead screw 53 is inserted into the fixing sleeve 52. The fixing sleeve 52 provides support for the lead screw 53 and ensures the stability of the lead screw 53 during rotation. A motor 54 is provided at the bottom of the mounting bracket 51. One end of the lead screw 53 is connected to the transmission end of the motor 54. The motor 54 provides rotational power for the lead screw 53 and converts the rotational power of the lead screw 53 into linear motion of the drive block 55. The drive block 55 is spirally sleeved on the outside of the lead screw 53. The drive block 55 provides a mounting base for the telescopic cylinder 57. A guide rail 56 is provided on one side of the mounting bracket 51. The drive block 55 is slidably mounted on the guide rail 56. The guide rail 56 provides guidance for the drive block 55 and ensures the stability of the drive block 55 during movement.

[0027] A telescopic cylinder 57 is provided on one side of the drive block 55. The telescopic rod of the telescopic cylinder 57 extends and retracts, driving the fixed plate 58 and the forming mold 511 closer to or further away from the glass tube. The top of the telescopic rod of the telescopic cylinder 57 is equipped with the fixed plate 58, which provides the mounting base for the forming mold 511. A pair of connectors 59 are symmetrically arranged on both sides of the fixed plate 58. Each connector 59 has a movably mounted flip-up buckle 510. The connectors 59 provide the mounting base for the flip-up buckle 510 and allow the flip-up buckle 510 to rotate a certain angle around the connector 59. The forming mold 511 is provided on one side of the fixed plate 58. The forming mold 511 is used to shape the flange of the heated glass tube. Its shape and size are determined according to the glass tube's shape and dimensions. The design requirements for the glass tube flange are determined. A pair of limiting blocks 512 are provided on the back of the forming mold 511. Limiting grooves are provided on the fixing plate 58 at the corresponding positions of the limiting blocks 512. The limiting blocks 512 cooperate with the limiting grooves on the fixing plate 58 to position the installation position of the forming mold 511 and ensure that the forming mold 511 is installed accurately. A pair of fixing posts 513 are symmetrically arranged on both sides of the forming mold 511. The fixing posts 513 pass through the flip buckle 510. One end of the fixing post 513 is threaded to the fixing cap 514. The fixing posts 513, through cooperation with the flip buckle 510 and the fixing cap 514, fix the forming mold 511 and ensure that the forming mold 511 will not loosen or shift during operation, thus ensuring the forming quality of the flange.

[0028] In use, the operator first places the glass tube between the clamping seats 310 on the rotating table 38. The extension of the telescopic rod of the telescopic cylinder 39 pushes the clamping seats 310 along the guide rail 311, causing several clamping seats 310 to move towards the center, thus clamping and fixing the glass tube. Then, the operator starts the motor 32, which drives the rotating shaft 33 to rotate. The rotating shaft 33 drives the gear 34 to rotate, and the gear 34 transmits power to the gear 36 through meshing, thereby driving the rotating shaft 35 to rotate, which in turn drives the rotating table 38 and the glass tube to rotate synchronously. Then, the operator can control the extension of the telescopic rod of the telescopic cylinder 41 to drive the arc-shaped mounting bracket 42 and its flamethrower 45 to rise to a suitable position. The flame is sprayed to uniformly heat the rotating glass tube. Then, the operator can extend the telescopic rod of the telescopic cylinder 3 57 to move the forming mold 511 directly above the preset processing position of the glass tube. Then, the motor 2 54 drives the lead screw 53 to rotate, converting the rotational motion of the lead screw 53 into the linear motion of the drive block 55, causing the drive block 55 to move downward along the guide rail 2 56, so that the forming mold 511 accurately abuts against the end face and side of the flange opening, ensuring the accuracy of the flange opening dimensions during the rotational heating process. After forming, the operator can turn off the flame sprayer 45, reverse the motor 2 54 to raise the forming mold 511 to a safe height, and then retract the telescopic rod of the telescopic cylinder 1 39 to remove the processed glass tube.

[0029] If the operator needs to replace the molding mold 511, first loosen and remove the fixing cap 514, then flip the buckle 510 so that the fixing post 513 can be disengaged from the buckle 510, and the molding mold 511 can be removed. Then, the operator can align the limiting block 512 on the back of the new molding mold 511 with the limiting groove on the fixing plate 58, then flip the buckle 510 so that the fixing post 513 passes through the buckle 510, and finally pick up the fixing cap 514, align it with the fixing post 513 and tighten it to complete the replacement of the molding mold 511.
