Description
Technical field
The present invention relates to preform process equipment, and in particular to preform is segmented and end face cuts angle device.
Background technology
With the development of preform industry, the external diameter of preform does bigger and bigger, and quality is also increasing, cutting
The increase of the hardness on surface, the cutting technique of large prefabricated optical fiber bar increasingly annoyings the development of each enterprise.
Cutting action is an aided process in prefabricated rods production procedure, it is necessary to many in prefabricated rods production overall process
Secondary entrance cutting action.
Existing two kinds of cutting technique：One kind is gas flame cuttiug；Another kind is machine cuts.Cut in actual production process
The rate of cutting of machine can influence the whole prefabricated rods production time, while the cut quality of cutting machine will also result in certain semi-finished product
And yield loss.Therefore, cutting equipment and technique are an important topics of current prefabricated rods manufacturing enterprise.
In existing sleeve pipe technique, prefabricated rod mandrel length after Longitudinal extending typically can all reach more than 3 meters, so
Be required for before one technique carrying out relevant segments, and be easy to after being segmented rear end operation vacuumizing and exhausting, it is necessary to
An exhaust angle is opened in prefabricated rods end, and crack-free at end face and angle is required to after all segmentations, the gas angle that begins to rehearse, and nothing collapses
Side.
, when angle is cut, near rotating blade, this cutting mode is to operation for direct hand-held barred body for existing machine cuts
Person requires easily chipping, breakage after height, and cutting.
The content of the invention
The present invention regarding to the issue above, overcomes at least one deficiency, it is proposed that a kind of preform segmentation and end face are cut
Angle device.
