Embodiment Construction

[0017] Refer to attached figure 1 , The structure of the miniature tight-packed stainless steel optical fiber unit includes optical fiber 2, optical fiber ointment 3, and stainless steel tube 1. An optical fiber 2 is installed in the stainless steel tube 1 and filled with optical fiber ointment 3 to form an optical fiber unit.

[0018] The production method of miniature tight-packed stainless steel optical fiber unit is as follows:

[0019] 1. Put the stainless steel coils on the steel belt rack, and then pull the steel belt to the steel pipe forming table through the steel belt tractor. The tension of the belt should be stable and there should be no shaking. The tension of the belt should be controlled at 80~90N.

[0020] 2. At the steel pipe forming table, the stainless steel strip is cut to the width required by the forming mold. The stainless steel strip is 6.2-6.3mm wide and 0.15-0.2mm thick, and then enters the φ2.0mm steel pipe forming mold. Wrap it into a stainless ...

Abstract

The invention discloses a minitype tightly packaged fiber unit and a production method thereof and relates to a high-strength minitype tightly packaged fiber unit produced by adopting specific equipment and production method and the production method thereof. The minitype tightly packaged fiber unit comprises a fiber, fiber balm and a stainless steel pipe, wherein the fiber is arranged in the stainless steel pipe and the fiber balm is filled in the stainless steel pipe to form the fiber unit. The production method comprises the following steps: (1) arranging a stainless steel coiled material on a steel band resting rack and sending a steel band to a steel pipe shaping table by a steel band hauling machine in a hauling way; (2) cutting the stainless steel band to the width needed by a shaping mould on the steel pipe shaping table, then entering into a steel pipe shaping mould, longitudinally packing into a stainless steel pipe with seams, leading the fiber in and filling the fiber balmin the stainless steel pipe simultaneously; completely welding the longitudinal seams of the stainless steel band longitudinally packaged and shaped by a laser beam welding machine and carrying out drawing by a drawing die for many times; (3) drawing the shaped minitype stainless steel fiber unit and taking in the fiber unit on a wire coil winding a steel pipe to obtain the minitype tightly packaged fiber unit.

Description

technical field [0001] The invention relates to a miniature tight-packed optical fiber unit and a production method thereof, which relate to a high-strength miniature tight-packed optical fiber unit and a production process manufactured by adopting special equipment and a production process. The ultra-fine stainless steel optical fiber unit can be used in national defense technology, field operations, railways, fire protection, medical equipment, oil well temperature measurement, power communication, cable temperature measurement, submarine optical cable and other system communications. Background technique [0002] At present, there are many enterprises producing stainless steel optical fiber units in our country, but they cannot produce stainless steel units of about φ1.0mm. Conventional stainless steel optical fiber units have the characteristics of poor bending performance, large volume, and limited scope of application. The stainless steel optical fiber unit of about φ...
