Abstract
The invention discloses a method for producing one-piece compressed hard glass fish collecting lamp bulb shell. The method comprises the following steps of: (1) selecting the specific size of a standard bulb shell to design the scheme of forming dies in advance, wherein in die materials, graphite or high-strength heat-resisting alloy can be used as blanks; (2) designing the bulb shell dies; (3) designing the two dies which have the same size, and forming feed holes with the diameters of between 30 and 50 millimeters uniformly at the upper ends of the two dies, wherein the two dies can be opened or closed under the mechanical control; (4) blanking hard glass melts continuously from a blanking opening and melting in a hard glass electric kiln at the high temperature of 1,200 DEG C, and conveying the hard glass melts into the dies directly from the feed holes of the dies; (5) after the hard glass melts are conveyed into the dies from the feed holes of the dies, introducing compressed air from the feed holes of the dies, and blowing; and (6) opening the dies, and cooling slowly to form the fish collecting lamp bulb shell. The method has the advantages that: the lamp bulb shell is fixed in a shape, uniform in outer diameter and wall thickness, standard in length and high stability and consistency; a large number of glass materials are saved; and the cost is reduced.
Description
Technical field
The present invention relates to quartz ware and make the field, field, be specifically related to a kind of production method of a compression moulding hard glass fishing lamp cell-shell
Background technology
At present, domestic electric light source industry is continued to use traditional working method to the production of fishing lamp shell with manufacturing always, the sheating material that adopts is filter ultraviolet silica tube, production method adopts glass work lathe flame integer and handblown technical matters, with Φ 60 ∽ 100mm, length is the filter ultraviolet silica tube of 500 ∽ 600mm, is fixed on an end of glass work lathe with anchor clamps; Start lathe then, directly fire silica tube in the rotation, when treating silica tube, carry out the manual blowing integer and seal, form the fishing lamp cell-shell after cooling near softening temperature with oxyhydrogen flame.The working method that this kind is traditional, a lot of defectives and deficiency are arranged, the one, silica tube is under high temperature and soft state during integer, variation has taken place in original shape and wall thickness, cause the consistence of external diameter, internal diameter and the wall thickness of cell-shell after the moulding relatively poor, particularly wall thickness differs, and makes easily to press with external pressure in the whole fishing lamp to be had a strong impact on, and reduces the work-ing life of fishing lamp; The 2nd, fire with moulding after, because of anchor clamps fixedly the part of silica tube 1/3rd can't secondary use, cause waste.
Summary of the invention
For addressing the above problem, the invention provides a kind of production method of a compression moulding hard glass fishing lamp cell-shell, it have cell-shell fixed in shape, external diameter unanimity, wall thickness evenly, consistence advantage preferably.For achieving the above object, the present invention adopts following technical scheme:
The production method of a compression moulding hard glass fishing lamp cell-shell comprises step:
(1) the concrete size of selected a kind of standard cell-shell is carried out the conceptual design of forming mould in advance, and moulding stock can use graphite or high strength thermal resistant alloy as the base material;
(2) cell-shell die design.During designing mould, with the internal diameter of mould respectively Fixed Design be the cell-shell shape of multiple different sizes such as Φ 60mm, Φ 80mm, Φ 100mm, Φ 120mm, the bottom design of mould is that circle is sealed or protruded circle and seals;
(3) die design is identical two of size dimension, and two moulds upper end average design have Φ 30-50mm feed port, and two moulds can folding arbitrarily under machinery control;
(4) after 1200 ℃ of the hard glass electric kiln continuous high temperature fusions, the hard glass melt is from the continuous blanking of feed opening, and directly sends in the mould by the die feeding hole;
(5) after the hard glass melt is sent into mould by the die feeding hole, blow 15 seconds blowing time, compressed air pressure pressure 0.1-0.2MPa, peak flow 1m3/min, but once shaped fishing lamp cell-shell at the feed port feeding pressurized air of mould then;
(6) open mould, after slowly cooling off, the moulding of fishing lamp cell-shell;
(7) but this technology continuity 24 hours produce.
Advantage of the present invention:
The first, adopt fixed mould, the high conformity of moulding cell-shell.
The second, the cell-shell external diameter can be adjusted and change at any time according to the size of die design and user's different demands.
The 3rd, cell-shell fixed in shape, external diameter unanimity, wall thickness evenly, length standard, stability, consistence are better, and have saved glass material in a large number, have reduced cost.
Embodiment
The enforcement of the technical program is described with specific embodiment below.
Embodiment one:
The one-time formed implementation step of Φ 60mm fishing lamp cell-shell:
Two fishing lamp cell-shell moulds that size is identical are installed on the anchor respectively, and under mechanical braking, folding arbitrarily;
After 1200 ℃ of the hard glass electric kiln continuous high temperature fusions, the hard glass melt is from the continuous blanking of feed opening, and directly sends in the mould by the die feeding hole;
When melted glass all enters in the mould, be 0.1-0.2MPa pressurized air with pressure, flow is 1m3/min, is pressed into mould from the upper port of mould, and melted glass is suppressed;
Mechanical manipulator is opened mould automatically, the moulding of Φ 60mm fishing lamp cell-shell.
The above; only be the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
