Abstract

The invention relates to a method for shaping the mouth of a round double-layer glass vessel, which effectively solves the problem that the mouth shape of a round double-layer glass vessel is not beautiful. The technical scheme for solving the problem is as following: an inner-layer glass tube and an outer-layer glass tube of a double-layer glass vessel to be processed are clamped on a rotary device to synchronously rotate at a speed of 30 r/min to 170 r/ min, and mouths of the inner layer and the outer layer to be welded are heated to be softened so as to be adhered together under the temperature of 696-2400 DEG C, the mouths of the inner layer and the outer layer are sufficiently melted to enable the outer-layer tube or the inner-layer tube to move in the direction far away from the mouth of the inner-layer tube or the outer-layer tube along the axial line, and a welding seam moves to an outer cup body in the range of 0.1 mm to 35 mm which is under the mouth. The stretched part is thinned to be about 0.1 to 0.95 time of the original thickness. In the stretching process, the parts which are not sufficiently softened can be heated by a flame and continuously softened. The invention has simple technology, convenient operation and good effect, and is the innovation in the processing field of double-layer glass.

Description

A kind of making method of oral area moulding of circular double-layer glass vessel

One, technical field

The present invention relates to the making method of the oral area moulding in glass processing field, particularly a kind of circular double-layer glass vessel.

Two, technical background

The making method of the oral area moulding of present circular double-layer glass vessel mainly contains direct welding aftershaping and mould control moulding, the oral area of welding aftershaping is perfectly round thick and heavy, lack graceful outward appearance, oral area as thermos flask, during with mould molding with mould contact and noncontact position between have significantly different, influence overall appearance if be used for vessel commonly used such as cup, the vestige of mould itself is difficult to eliminate, destroyed the permeability of glass, because the lamellar spacing of double-layer glass vessel is little, but a large amount of tests and production practice proof can be made the oral area moulding of individual layer with mould is difficult to produce the oral area shape of the bilayer of smooth grace, therefore moulding process is unreasonable is to cause the inaesthetic major reason of double-layer glass vessel oral area, also be one of the sale of double-layer glass vessel and major reason that use is restricted, be born the more than ten years such as the double glazing cup, but can't obtain 1/10th the market share of single-glass cup and be accepted by masses, develop a kind of making method of oral area moulding of smooth graceful bilayer so?

Three, summary of the invention

At above-mentioned situation, for overcoming the prior art defective, the present invention's purpose just provides a kind of making method of oral area moulding of circular double-layer glass vessel, can effectively solve the inaesthetic problem of oral area moulding of double-layer glass vessel, the technical scheme of its solution is, the internal and external layers of glass pipe of the double-layer glass vessel that will process is clamped on the rotating equipment, rotation synchronously, the speed of rotation is 30-170 rev/min, the ectonexine oral area that heating will be welded, make it deliquescing, bonding together, the back is abundant merges, 696 ℃-2400 ℃ of Heating temperatures, the row's of use fire during heating, keep internal layer pipe or outer pipe axially motionless, skin or internal layer pipe are produced move away from the direction of internal layer or outer tube rim of the mouth portion along axis, weld movement is to outer cup, and the position is in the scope of the downward 0.1-35 millimeter of oral area, be stretched 0.1-0.95 that the position is thinned to original thickness doubly, can continue softening this position with flame heating when some position is fully not softening if find in the stretching.Technology of the present invention is simple, and is easy to operate, effective, is an innovation in the double glazing manufacture field.
