Abstract
The invention relates to a machine blowing molding technology for a glass lamp shade. The process feature lies in the following steps: a, melting frit; b, pre-heating a die to 400-600 DEG C; c, starting up an air compressor to enable compressed air to enter a working system; d, gathering materials in the way that a gatherer picks the cooked frit out of a crucible according to a proper weight and places the cooked frit in the bottom die center of a stamping die of a flat-plate aerostatic press; e, using the flat-plate aerostatic press to press glass cakes; f, forming a semi-finished product through a tread table; g, blowing to form a finished product in the way that a molding worker places a blowing molding die at the opening part of the semi-finished product in a back-off manner, starts up a compressed air switch of the molding tread table to blow the semi-finished product into the finished product and then starts up the blowing molding die; h, annealing in the way that a shade taking worker takes the finished product out of a tread table shaping die and gives the finished product to a shade delivery worker and the shade delivery worker feeds the finished product into an annealing furnace for annealing; and i, drilling in the way that a drilling worker performs drilling on the bottom of a lamp shade. The machine blowing molding technology has the advantages that fire finishing is not required, so that the energy consumption is reduced; counterfeit bubbles are not needed, so that the frit usage rate is high; the production cost is low; and the molding time is shortened.
Description
Technical field
The present invention relates to a kind of machine pressure blow-molded glass lamp shade forming technology, belong to muffle field shaping technique.
Background technology
At present, the production method (prior art) that muffle is conventional is technological process for blowing, is exactly first play material with manually blowing bar, shaping in blow mold, then sticky end excision product vacation bubble, the mouth that reburns, sizing.This production method produces false bubble, thus causes frit rate of utilization low; Need to burn mouth, consume diesel oil many; Production cost is high.
Summary of the invention
Object of the present invention will provide one need not burn mouth, energy efficient exactly; Do not have false bubble, frit rate of utilization is high; The muffle moulding process that production cost is low.
Technical scheme of the present invention is as follows: a, fusion cast glass material: utilize prior art and common equipment, raw material to melt frit; B, preheated mold: dull and stereotyped pneumatic press pressing mold, step on platform stock mould and blowing stock mould be preheated to 400 DEG C-600 DEG C; C, unlatching air compressor machine: open air compressor machine, make compressed gas enter work system; D, choose material: to be chosen from crucible by suitable component mutually by well-done frit by bit-gatherer and be placed on dull and stereotyped pneumatic press pressing mold bed die central authorities; E, pressed glass material cake: cut material work Special scissors and frit clout is cut off, open dull and stereotyped pneumatic press switch, frit is pressed into specified dimension frit cake; F, step on platform molding semi product: frit cake takes out from dull and stereotyped pneumatic press pressing mold bed die by film releasing work, is placed on and steps on platform stock mould centre; Step on platform work pine to open and shapingly step on platform stock mould drift, mold work in-process oral area shape together with sizing work, then pine opens shaping platform stock mould drift of stepping on to specified altitude 80-120mm; G, blow molding finished product: blowing stock mould is tipped upside down on work in-process oral area by sizing work, opens the shaping compressed gas switch stepping on platform, and work in-process are blown out finished product, open blowing stock mould; H, annealing: get cover work and taken out from stepping on platform stock mould by this finished product, transfer to send cover work to send annealing furnace annealing to; I, boring: drillman holes to lampshade bottom.
The invention has the beneficial effects as follows: 1. adopt streamline operration, shortening forming time, improve output.Blow molding produces this like product time, split run (general 10 people are a class) about 700, and machine pressure blowing split run can produce nearly 3000;
2. mouth need not be burnt, energy efficient.A daily diesel oil 200kg of consumption stove, for two blowing classes, and can only suppress blowing process, need not burn mouth, saving fuel oil loss; 3. the blowing of machine pressure does not have false bubble, improves frit rate of utilization.Reduce operation otch, technological process for blowing 30% vacation bubble, frit rate of utilization only has 70%, and it just must can complete formed product process with otch, burning mouth two-step, and suppresses blowing process frit rate of utilization more than 95%; 4. reduce costs.Technological process for blowing is fewer than technological process for blowing burns mouth, otch operation for machine pressure, improves frit rate of utilization simultaneously, thus can energy efficient, reduce artificial, this kind of moulding process cost is greatly reduced.Blowing HJC330 muffle production cost is 4.50 yuan/, and machine pressure blowing production HJC330 muffle cost only has 2.50 yuan/.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
(1) fusion cast glass material: utilize prior art and common equipment, raw material to melt frit; (2) preheated mold: dull and stereotyped pneumatic press pressing mold, step on platform stock mould and blowing stock mould be preheated to 400 DEG C-600 DEG C; Die temperature is too low causes mouldable glass material to be exceedingly fast sclerosis, and product difficulty is shaping; Too high fragile mould, causes frit and mould adhesion, causes the difficult demoulding or shaping imperfect; (3) air compressor machine is opened: open five cubic metres of air compressor machines, make compressed gas enter work system; (4) material is chosen: to be chosen from crucible by suitable component mutually by well-done frit by bit-gatherer and be placed on dull and stereotyped pneumatic press pressing mold bed die central authorities; (5) pressed glass material cake: cut material work Special scissors and frit clout is cut off, open dull and stereotyped pneumatic press switch, frit is pressed into specified dimension frit cake; (6) platform molding semi product is stepped on: frit cake takes out from dull and stereotyped pneumatic press pressing mold bed die by film releasing work, is placed on and steps on platform stock mould centre; Step on platform work pine to open and shapingly step on platform stock mould drift, mold work in-process oral area shape together with sizing work, then pine opens shaping platform stock mould drift of stepping on to specified altitude 80-120mm; (7) blow molding finished product: blowing stock mould is tipped upside down on work in-process oral area by sizing work, opens the shaping compressed gas switch stepping on platform, and work in-process are blown out finished product, opens blowing stock mould; (8) anneal: get cover work and this finished product is taken out from stepping on platform stock mould, transfer to send cover work to send annealing furnace annealing to; (9), hole: drillman holes to lampshade bottom.
Whole process speed wants fast, otherwise frit sclerosis, unfavorable formed product; Will send into compressed gas in right amount during the sizing of blowing stock mould, cause glass hardening, otherwise product blowing position is easily caused and subsided; Whole process attentional manipulation glass doses, otherwise blowing position is excessively thin, unfavorable product post-treatment.
