Abstract
The present invention discloses a technology for producing a high-precision glass and quartz capillary, which comprises the steps: raw materials for manufacturing the capillary is put into a feed inlet of a melting furnace and is processed inside the melting furnace; simultaneously, a metal wire is stretched into the feed inlet of the melting furnace by using a metal wire driving device and a metal wire positioning device, and is put into the melting furnace; a glass rod or a quartz rod which is processed by using the melting furnace is stretched, and the metal wire is wrapped inside the rod to move along with the rod; a product can be obtained after the metal wire is removed from the glass rod or the quartz rod which is obtained after stretched, etc. In the present invention, the metal wire positioning device and the metal wire driving device are added to a traditional device for producing the glass and quartz capillary by using hot melt stretching, and the high-precision glass and quartz capillary with an inner diameter within one millimeters can be produced; a porous capillary which has more than two inner holes in a shape of a rectangle, an oval, etc. can be produced, and the purpose that the produced capillary has high precision and well concentricity can be ensured.
Description
Technical field:
The present invention relates to a kind of production technique capillaceous.
Background technology;
The technology of existing production capillary glass, silica tube, still can not produce internal diameter 1mm with interior high-accuracy glass and quartz capillary, also can't produce the above porous capillary in shape endoporus such as having rectangle, ellipse and two holes, can't guarantee that also the kapillary of producing has desired accuracy requirement.
Summary of the invention:
Technical solution of the present invention is:
The production technique of a kind of high-precision cullet, quartz capillary is characterized in that: comprise the following steps:
1. will make raw material capillaceous and drop into the smelting furnace dog-house, enter furnace process, simultaneously wire be stretched into the smelting furnace dog-house through metal wire drive device and wire locating device, enter smelting furnace;
2. will stretch through the glass or the quartz pushrod of furnace process, wire is enclosed in the rod and moves together;
3. the glass or the quartz pushrod that will obtain after will stretching are removed wire wherein, get product.
The wire wire drive device is adorned wrapping wire roller bearing wiry, and wrapping wire roller bearing rear is provided with the seal wire roller.The wire locating device has positioning body, and wire hole is set in the positioning body.Wire hole is single hole, diplopore or porous.Wire hole is circle, rectangle, ellipse, trilateral or abnormity.The 3. middle removal of step method wiry adopts the acid corrosion method.
The present invention stretches at traditional hot melt and produces on the device basic of glass, quartz capillary, wire locating device and wire wire drive device have been increased, can produce internal diameter 1mm with interior high-accuracy glass and quartz capillary, energy production have the above porous capillaries of shape endoporus and two holes such as rectangle, ellipse, can guarantee that the kapillary of producing has high precision and good concentricity.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the process flow sheet of one embodiment of the invention.
Fig. 2 is the configuration diagram of wire locating device among Fig. 1.
Embodiment:
The production technique of a kind of high-accuracy glass, quartz capillary comprises the following steps:

2. will stretch with stretching and drawing equipment 5 by the prior art ordinary method through the glass or the quartz pushrod of furnace process, wire is enclosed in the rod and moves together, during stretching, adopt the method for laser diameter measurement Controlling System same as the prior art 6 control kapillary external diameters to control the kapillary external diameter;
3. the glass or the quartz pushrod that will obtain after will stretching are immersed in erosion removal wire wherein in the acid solution, get product.General nitric acid, sulfuric acid or other acid solutions that adopts 10% above concentration (example 10%, 30%, 50% etc.) of acid solution.Also can adopt other suitable acid solutions of other concentration.
Above-mentioned wire wire drive device has the wrapping wire roller bearing 7 of dress wire 3, and wrapping wire roller bearing 7 rears are provided with seal wire roller 8.Wire locating device 4 has positioning body 9, and wire hole 10 is set in the positioning body 9.Wire hole is circular diplopore form (or adopt single hole or porous, be shaped as rectangle, ellipse, trilateral or odd-shaped wire hole).Set a pulley 11 on the positioning body 9, further help the wire location.
Remove methods such as method wiry can also adopt that machinery reels off raw silk from cocoons.
The present invention is by wire wire drive device and wire locating device, make wire be stabilized in the glass of required stretching generation and the specific position of quartz pushrod, begin then to stretch, and wire and glass stick are moved simultaneously, like this, the wire specific position that just is fixed on glass stick has suffered.Adopt the method for bite, take down wire, just obtain required kapillary, the wire of different shapes and diameter just can obtain different glass capillaries in different positions.
