Description

Technical Field

[0001] This utility model relates to the field of glass tube bending technology, specifically to a glass tube multi-angle bending forming tool. Background Technology

[0002] Glass tube bending is common in industrial production, such as in the manufacture of glass instruments, lamps, or decorative items. Patent publication CN221370974U discloses a capillary glass tube bending device, which includes a base plate, a retractable support rod connected to the top of the base plate, a horizontal sleeve connected to the top of the support rod, a partially exposed glass tube inserted into the sleeve, and a screwing mechanism for tightening the glass tube at its opening; additionally, a vertical connecting plate connected to the top of the sleeve, a horizontal plate vertically connected to the top of the connecting plate, a pressure block located above the exposed portion of the glass tube below the horizontal plate, and an arc-shaped opening at the bottom of the pressure block that matches the outer side of the glass tube; furthermore, a drive mechanism for raising and lowering the pressure block is provided on the horizontal plate; the drive mechanism... The structure includes a screw threaded through a horizontal plate and located vertically, with a bearing connected between the screw and the top of the pressure block. In the aforementioned patent, a softened glass tube is inserted into a sleeve, and the pressure block is moved downwards by manually rotating the screw, thus bending the glass tube. However, in this patent, the screw rotates and moves vertically, while the pressure block at its bottom rotates and moves accordingly, failing to achieve simple movement. Although the patent includes a bearing at the contact point between the pressure block and the screw, this alone is insufficient to ensure the pressure block can only move without rotating. An additional structure guiding the pressure block is needed to achieve proper movement, and this aspect urgently requires improvement. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a glass tube multi-angle bending and forming tool with a simple structure, reasonable design, and convenient use. In addition to ensuring that the first pressure block does not rotate during the descent, a second pressure block is added to press the glass tube horizontally, thereby achieving bending at more angles.
