Glass lamp shade forming process by machine pressuring and blowing

Abstract

The invention discloses a glass lamp shade forming process by machine pressing and blowing. The process is characterized by comprising the following steps of: a, melting the glass material; b, preheating dies to 400-600 DEG C; c, starting the air compressor: starting the air compressor to introduce the compressed air into the work system; d, selecting material: selecting the boiled glass material from the crucible according to the appropriate weight by a selector and placing the glass material in the center of the bed die of the flat-plate air compressor pressing die; e, pressing the glass material cake with the flat-plate air compressor; f, forming the semi-finished product with paddle table; g, forming the finished product by blowing: reversely covering the blowing forming die on the sub-opening of the semi-finished product by a former, starting the compression air switch of the forming paddle table to blow the semi-finished product to the finished product, and starting the blowing forming die; h, annealing: taking the finished product from the paddle table forming die by a shade taker and sending the shade to a shade sender, and sending the the shade to an annealing furnace for annealing; and I, drilling: drilling a hole at the bottom of the lamp shade by a driller. The invention has the advantages of no fire finishing, low energy consumption, no false bobble, high use rate of glass material, low production cost, short forming time and the like.

Description

technical field [0001] The invention relates to a molding process for a glass lampshade, in particular to a molding technology for a machine-pressed blown glass lampshade. Background technique [0002] The production method (prior art) commonly used of glass lampshade at present is a blowing process, is exactly to start material with manual blowing rod earlier, is molded in blowing mould, sticks the bottom and excises product false foam again, burns mouth again, finalizes the shape. This production method produces false bubbles, which leads to low glass frit utilization rate; requires burners, consumes more diesel oil; and has high production costs. Contents of the invention [0003] The object of the present invention is to provide a glass lampshade molding process that does not need a burner, saves energy consumption, has no false bubbles, has a high utilization rate of glass frit, and has low production costs. [0004] Technical scheme of the present invention is as fo...
