Abstract
The utility model discloses a bowl, which comprises a wall and a hole. A transitional round corner is arranged at a connection position of the wall and the hole, and an arc-shaped vertex of the transitional round corner faces to the outer side of the wall. The radius of the transitional round corner ranges from 6mm to 30mm. The bowl has the advantages that the arc-shaped vertex of the transitional round corner faces to the outer side of the wall, molten glass can be effectively prevented from overflowing from the hole due to self weight, and radian diameter of the transitional round corner is increased so that a punch can adsorb the molten glass better. By means of changing the direction and the radius of the transitional round corner, the problem of control of shapes and weights of materials when large-tonnage products are produced is resolved well, so that the perfect shapes and the perfect weights of the materials are realized. The bowl guarantees that the molten glass fast fully fills a model by moving the shortest distance during pressing, so that surface kink marks and temperature differences of various portions of glass parts are reduced, and the bowl creates necessary conditions for temperature equalization and tempering of the glass parts for a next working procedure, guarantees the quality of the products and creates benefits for enterprises.
Description
Technical field
The utility model relates to a kind of feeding machine part, relates in particular to a kind of orifice ring that large tonnage product uses that is suitable for.
Background technology
In the glasswork production technique, the gob shape determines the glass workpiece quality of being suppressed to a great extent, and orifice ring is one of two big key equipments that obtain desirable gob shape.In the gob production process, allow the weight of gob and shape in orifice ring, push as far as possible and form by the drift of artificial control, get rid of the influence of effects such as gravity.Also have, feeding machine prevents that gob from leaking a very important technology of discharge hole downwards because of conducting oneself with dignity, and exactly in drift makes progress process, forms negative pressure between drift and material hole.
Orifice ring at present commonly used as shown in Figure 1, it is the knuckle of 5mm that radius is all adopted in the junction in the material hole of bowl wall and lower end, and the circular arc summit of this knuckle is towards medullary ray one side of orifice ring, smooth transition between bowl wall and the material hole.When this kind orifice ring is used for the production of miscellaneous goods, because miscellaneous goods material heavy and light, and the machine speed of drift is fast, glass metal residence time in feeding machine is short, the heavy control easily of material shape and material; It is fast that drift is done even undulatory motion along the medullary ray of orifice ring, the bowl wall and the material hole between smooth transition be beneficial to glass metal from the material hole extrude smoothly; But when producing large tonnage product, because temperature of glass liquid is about 1200 degree, the glass metal gob is heavy, and the machine speed of drift is slow, and drift is relatively slow when the medullary ray of orifice ring is done even undulatory motion, so drift is when suction, gob can not adsorbed by drift because of deadweight, and free-falling can not form ideal gob shape, weight is also uncontrollable, has brought difficulty to production; And glass metal residence time in feeding machine is longer relatively, and glass metal will spill downwards from the material hole because of deadweight, and the influence of gravity factor is difficult to artificial control, causes material shape long and too short, makes glass workpiece easily produce surface imperfection.
The utility model content
The utility model is at the existing in prior technology deficiency, and provides a kind of simple in structure, reasonable in design, can effectively control the orifice ring of gob shape and weight.
The utility model is realized by following measure: a kind of orifice ring, comprise bowl wall and material hole, and wherein: the junction between described bowl wall and the described material hole is provided with knuckle, and the circular arc summit of described knuckle is towards the outside of bowl wall.
The radius of described knuckle can be 6-30mm.
The radius of described knuckle can also be 15-30mm.
The beneficial effect of this programme can be learnt according to the narration to such scheme, and is simple in structure, reasonable in design.The circular arc summit of knuckle can prevent effectively that towards the outside of bowl wall glass metal from overflowing from the material hole because of deadweight; Increase the radius of the radian of knuckle, be convenient to drift and adsorb glass metal better, prevented that further glass metal from leaking discharge hole downwards because of deadweight; By the direction of change knuckle and the size of radius, when well having solved the production large tonnage product, the problem of material shape and weight control, thereby obtain ideal material shape and expect heavy, guaranteed when compacting, allow glass metal move shortest distance, fill up model very soon, so that reduce the temperature difference of surperficial folding line and minimizing glass workpiece each several part, created prerequisite for the equal gentle tempering of glass workpiece next process, the qualification rate that makes glass workpiece is brought up to about 70% from about 30%, guaranteed quality product, for enterprise has created benefit.
Description of drawings
Fig. 1 is the structural representation of orifice ring in the prior art;
Fig. 2 is the structural representation of the utility model embodiment.
Among the figure, 1, the bowl wall; 2, knuckle; 3, material hole.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by embodiment.
As shown in Figure 2, a kind of orifice ring comprises bowl wall 1 and material hole 3, and wherein: the junction between bowl wall 1 and the material hole 3 is provided with knuckle 2, and the circular arc summit of knuckle 2 is towards the outside of bowl wall 1, and the radius of knuckle 2 is 20mm.
The circular arc summit of knuckle 2 is towards the outside of bowl wall 1, can prevent effectively that glass metal from overflowing from material hole 3 because of deadweight, by adjusting drift and barrel, just can obtain suppressing required wax gourd shape material shape, and the heavy control easily of material, its objective is that the shape that makes gob is similar to the size shape of product, during compacting, allow glass metal move shortest distance, fill up model very soon, so that reduce the temperature head of surperficial folding line and minimizing glass workpiece each several part, avoid improving the glass workpiece quality because of the long and too short generation glass workpiece of material shape surface imperfection.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
Claims (3)
