Abstract

The invention discloses a processing device and a processing method of a prefabricated rod conical head. The processing device comprises a mounting plate, an upper clamp, a lower clamp, a heating mechanism, first driving equipment and second driving equipment; the upper clamp is arranged on the mounting plate and is used for clamping the top of a preform; the lower clamp is movably assembled on the mounting plate, is positioned below the upper clamp and is used for clamping or loosening the bottom of the preform; the heating mechanism is provided with a heating area, and the heating area is used for accommodating and heating the preform; the first driving equipment is assembled on the mounting plate, is connected with the lower clamp and is used for driving the lower clamp to be close to or far away from the upper clamp; the second driving equipment is connected with the mounting plate and used for driving the mounting plate to ascend and descend. The problem that the shape and the size of the conical head are difficult to unify due to a gravity cone falling mode is solved.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform processing, in particular to a processing device and a processing method for a preform cone head. Background technique [0002] Increasing the drawing length of a single optical fiber preform can effectively improve optical fiber production efficiency and reduce manufacturing costs. Therefore, optical fiber preforms are gradually developing towards larger sizes, and the length of a single rod can reach thousands of kilometers. [0003] As far as the manufacturing technology of large-scale optical fiber preform is concerned, a two-step manufacturing process is mainly used at present, that is, a core rod with a certain refractive index profile and geometric size is prepared first, and then a cladding with a certain thickness is outsourced. Among many outer cladding manufacturing processes, the sleeve method (RIC) is easy to produce large-size optical fiber preforms with stable optical...
