A bend pipe forging die with a springing device comprises a fixed die body and a movable die body, wherein the movable die body is arranged below the fixed die body; a convex die body is arranged on a forging surface of the fixed die body; a concave die body which is matched with the convex die body is arranged on a forging surface of the movable die body; the convex die body is matched with the concave die body to form a forging cavity of which the shape is matched with that of a bend pipe; the springing device is arranged in the movable die body; a downward blind hole is formed in the forging surface of the movable die body; the springing device comprises a first spring arranged at the bottom of the blind hole and a pressure lever arranged on the first spring; the upper end of the pressure lever extends out of the blind hole; the upper part of the pressure lever is a wedge-shaped surface; a through hole is formed in a position, which corresponds to the forging cavity, of the wedge-shaped surface; a push rod which is matched with the wedge-shaped surface of the pressure lever is arranged in the through hole; and a resetting spring is arranged on the push rod. The springing device is arranged in the movable die body, so that a finished bend pipe can be unloaded from the die when stripped from the die; the labor intensity of workers is reduced; and the forging efficiency of the bend pipe is improved remarkably.

The invention relates to pressure meter assembling equipment. A pressure meter is conveyed below a mounting mechanism by a feeding mechanism; a clamping lifting cylinder of the mounting mechanism drives a lifting connection plate to move up and down on a lifting slide rail, a cam is driven to lift, the cam is descended to drive a meter clamping lever to clamp the pressure meter, the cam is ascended to drive the meter clamping lever to loosen the pressure meter, firstly, the meter clamping lever is loosened, a lifting mechanism drives the mounting mechanism to move downwards to clamp the pressure meter, the feeding mechanism returns back to the initial position, then a rotary mechanism is moved to drive a pressure meter seat to move to a place below the mounting mechanism, a compressing mechanism clamps the pressure meter seat, the mounting mechanism is driven by the lifting mechanism to move downwards, and when the pressure meter reaches a place above the pressure meter seat, the mounting mechanism is driven to drive a rotary spindle to rotate, so the pressure meter is rotated and descended to be screwed into the meter seat, and when the torsion achieves a certain value range, the pressure meter stops rotating. The assembly of the pressure meter is full-automatically performed, the labor intensity of operation staff is reduced, and the production cost is reduced.

The invention discloses a process for modifying an optical fiber preform, comprising the steps of 1) using a quartz rod cutter to cut a rod preform to obtain a primary quartz rod; 2) secondarily processing the primary quartz rod in a secondary former to obtain a secondary quartz rod; 3) embedding a conductive material in the secondary quartz rod, and sealing with a sealing machine to obtain the optical fiber preform. Special cutting equipment is used herein, zero offset from the axis can be ensured during cutting of a quartz rod, a variable-frequency speed-adjusting motor is arranged in a motor box, speed adjusting is facilitated, and resource and energy can be saved. Special secondary forming equipment is provided, and manual and electric feeding can be achieved; special sealing equipment is also used, non-uniform local distribution of film is avoided, and the preform is more attractive.
