Manufacturing method of cross discharge tube

Abstract

The invention relates to a processing technology of internal components and parts in a laser, and provides a processing and making method of a cross-shaped discharge tube; the cross-shaped discharge tube is prepared by a plurality of steps including blanking, pretreatment, fixing, welding, cutting, trimming, chamfering, annealing, straightness accuracy shape righting and the like. According to the processing and making method of the cross-shaped discharge tube, by involvement of a mould, a work fixture and other external auxiliary ways, dependence of glass processing on artificial factors in local links can be reduced, and the quality of the production of glass processing is improved; the cross-shaped discharge tube made by the process method can meet technical requirements that position dimension precision of a welding position of the cross-shaped discharge tube in a high power laser is controlled within + / -0.5mm in general, installation dimension precision is controlled within + / -0.5mm, and straightness accuracy is controlled below 0.3mm and the like, so that the development of high power gas lasers can be promoted.

Description

technical field [0001] The invention relates to a processing technology of components in a laser, in particular to a processing method for a cross-shaped discharge tube. Background technique [0002] A laser is a device that uses the principle of stimulated radiation to amplify or oscillate light in certain excited substances. A gas laser is a device that uses gas or vapor as a working substance to generate laser light. It consists of three main parts: the activated gas in the discharge tube, the resonant cavity formed by a pair of mirrors, and the excitation source. [0003] At present, high-power gas lasers are widely used in cutting, welding, cladding and other industries. The demand for high-power gas lasers in domestic and foreign processing markets is increasing year by year. While a large number of imported high-power gas lasers are pouring into the market, domestic high-power gas lasers have gradually begun to rise, and their processing and use performance has grad...

AI Technical Summary

Problems solved by technology

Therefore, it is determined that traditional glass processing (including foreign countries) is all manual processing, and the processing accuracy of glass products is difficult to guarantee. Handmade products make the quality of mass-produced discharge tubes unable to maintain consistency and repeatability.

The processing accuracy of the external dimensions of traditional glass products after manual processing is generally controlled at ±2mm, which cannot meet the requirements for the processing accuracy of the cross-shaped discharge tube to be controlled within ±0.5mm; in addition, manual The finished product makes the quality of mass-produced discharge tubes unable to maintain consistency and repeatability

This phenomenon makes it impossible for the new core technology of laser resonator cross discharge tube to be replicated and mass-produced in large quantities.
