Abstract

The invention belongs to the technical field of devices special for manufacturing discharge tubes, discharge lamps and parts of the discharge tubes and the discharge lamps. A lamp filament pressing mechanism comprises an air cylinder and a pressing device, the front end and the rear end of the air cylinder are provided with an air inlet and an air outlet respectively, a lead screw is in eccentric fit with a piston in the air cylinder, the free end of the lead screw is connected with an output shaft of the air cylinder, and a clamping strip is arranged on the output shaft of the air cylinder; a main shaft capable of linearly moving is arranged in the pressing device, a groove matched with the clamping strip is formed in the main shaft, and a spring is arranged between the main shaft and a shell of the pressing device; a wedge block is fixed to the tail end of the main shaft, a pair of oscillating rods hinged to the shell of the pressing device is arranged on the two sides of the wedge block, a core block is arranged between the oscillating rods, and a pair of opposite clamping blocks are arranged at the tail ends of the oscillating rods. Through the pressing mechanism, tungsten wires and core columns can be automatically pressed, working efficiency is high and quality consistency is high.

Description

technical field [0001] The invention belongs to the technical field of equipment specially used for manufacturing discharge tubes, discharge lamps and components thereof. Background technique [0002] In the production field of electric light source products, the main purpose of the wire stretching machine is to automatically bind the tungsten wire to the guide wire of the stem, and complete guide wire shaping, bottom wire cutting, guide wire flattening, guide wire There are multiple production processes such as hooks, automatic tungsten wire loading, electronic powder dipping, and protective rings. In the whole process, the most important thing is that after the tungsten wire is fed into the hook of the stem guide wire, the filament is pressed against the stem guide wire to form a whole. Due to the thin filament, the current process is manually operated, with low work efficiency, poor quality consistency and high production cost. Contents of the invention [0003] The i...
