Embodiment Construction

[0019] refer to Figure 1 to Figure 6 , what the present invention describes is a core-containing extrusion molding method for a ceramic pin blank tube, the steps of which are: extruding the extruded sludge 12 in an extruder containing an extrusion head to form a core-containing wire The pin material 10 of 9, after the material 10 is straightened and dried, the pin material 10 is machined to make pin blanks 18.1, 18.2, 18.3, and then the pin blanks are obtained by degreasing and high-temperature sintering Tube.

[0020] A further technical solution may be: automatically and continuously wrap the core wire 9 of a certain diameter in the center of the ceramic mud 12 during the extrusion process of the ceramic mud 12 to become the pin material 10, and after the material 10 is dried, extract the core Silk 9 obtains the central aperture.

[0021] A further technical solution may also be: use a machine tool to mechanically process the material 10, cut off, chamfer, and process the...

Abstract

The invention is a contact pin perform tube core containing ejecting shaping method and its ejecting head of which the feature is that eject the clay from the ejector with an ejecting head to form a contact pin material with a core filament inside which is processed with machine after the stretching and baking to obtain the contact pin perform which can obtain the contact pin perform tube by defatting and high temperature agglomeration. The perform tube of the invention is easily processing and of high accuracy.

Description

technical field [0001] The invention relates to a core-containing extrusion molding method of a ceramic ferrule blank tube and an extrusion head thereof, in particular to a core-containing extrusion molding method and an extrusion head of a ceramic pin blank tube used as an optical fiber connector. Background technique [0002] Optical fiber connectors widely used in the field of optical fiber communication are passive devices used for on-off connection of optical fibers, and their core components are ceramic ferrules that fix optical fibers and make them coaxial with each other. The ceramic ferrule is a thin ceramic tube with a 0.125mm hole. Currently commonly used models have an outer diameter of 2.5mm and a length of 10.5mm. In order to ensure the efficiency and reliability of optical fiber transmission, the dimensional accuracy and coaxiality of the outer circle and inner hole of the ceramic ferrule are required to be within 0.5μ. [0003] Ceramic pins are mixed with c...
