Abstract
The invention discloses hot bending reinforced glass. Any surface (an upper surface, a lower surface or both the upper surface and the lower surface) at the arc edge of the glass is provided with a bevel edge. The thickness of the glass is 5 mm to 25 mm and the width of the bevel edge is 5 mm to 100 mm. The glass can be single-pane glass, hollow glass or laminated composite glass. A processing method of the hot bending glass comprises the following steps: firstly, preprocessing the edge to be bended into an arc edge; processing any surface (the upper surface, the lower surface or both the upper surface and the lower surface) at the arc edge of the glass to form a bevel edge; and finally conducting hot treatment processing. The invention solves the problem that the arc edge of the prior artis easily cracked and even damaged during the hot treatment forming of the glass.
Description
Technical field
The present invention relates to the glass processing field, especially relate to a kind of processing method of reinforcing glass and hot bending glass of hot bending.
Background technology
The purpose of the processing of simple glass mainly is to prevent incised wound, realize appearance looks elegant, satisfy heat treatment requirements.The reinforcing glass of hot bending has generally comprised half tempered glass, tempered glass and superpower tempered glass, its heat treatment considers that mainly the micro-crack expansion of glass edge portion causes the crackle diffusion, can expand rapidly because of micro-crack and cause breaking when glass enters these micro-cracks of hot environment, so mainly be tempered glass by heat treated safety glass at present.
The inventor is by long-term a large amount of knowhow and experimental datas, find that glass is in doing heat treatment palintrope forming process, if the glass radius of curvature of design is too small, then easily extrude and cause stress too concentrated because of the glass that softens limit portion occurs in forming process, glass cracks, fracture phenomena thereby cause.
In view of this, the inventor studies in great detail and explores at this defective of hot bending glass specially, develops a kind of hot bending glass.Develop the processing method of this hot bending glass simultaneously, the application kind of hot bending glass is increased greatly, this case produces thus.
Summary of the invention
One object of the present invention is to provide a kind of reinforcing glass and processing method thereof of hot bending, to solve the problem that the heat-treating profiled process arc of glass limit cracks even breaks in the prior art.
In order to reach above-mentioned purpose, solution of the present invention is:
The invention provides a kind of reinforcing glass of hot bending, have hypotenuse on arbitrary surface on glass arc limit (upper surface, soffit or upper and lower surface are simultaneously).The thickness of described glass is 5mm～25mm, and the width of hypotenuse is 5mm～100mm.Glass can be monolithic glass, hollow glass or interlayer composite glass.
In addition, the present invention also provides a kind of processing method of hot bending glass, earlier the limit portion of desiring to curve the arc limit is carried out preliminary treatment, arbitrary surface (upper surface, soffit or upper and lower surface are simultaneously) on glass arc limit is processed to form hypotenuse, and then heat-treats processing.This heat treatment process steps in sequence comprises heating, brake forming, blowing, process for cooling.Described glass can be monolithic glass, hollow glass or interlayer composite glass.The thickness of glass is 5mm～25mm.The width of hypotenuse is 5mm～100mm.
The mode of described formation hypotenuse is cutting or grinding.
Described wheel cutting, water cutting or the laser cutting of being cut into; Described grinding is correct grinding, fine grinding, corase grind or chamfering.
Product of the present invention and method are mainly used in building doors and windows, curtain wall, family property, sanitary equipment, dining table tea table, showcase, refrigerator-freezer, shower room, balcony and land the manufacture field of glass such as glass, household electrical appliances, the limit portion crooked position place that can reduce the little glass product of radius of curvature produces metaboly, can improve yield rate by the processing method that adopts above scheme.
In addition, adopt the reinforcing glass of hot bending of the present invention can reduce the glass heat processing time.Especially at than heavy sheet glass, elongated thick more heat time heating time when glass, and glass surface will produce pit during near softening point.The present invention can reduce heat time heating time and eliminate pit (heat spot) and the power consumption that the surface causes, when producing the hot bending glass of slab, can reduce by 5%～20% power consumption, has good economic benefit.
Description of drawings
Fig. 1 is the product appearance figure of the reinforcing glass of hot bending of the present invention;
Fig. 2 is the product cross section figure of the reinforcing glass of hot bending of the present invention, and upper and lower surface all forms hypotenuse;
Fig. 3 is the product cross section figure of the reinforcing glass of hot bending of the present invention, and only upper surface forms hypotenuse;
Fig. 4 is the product cross section figure that increases glass of hot bending of the present invention, and only soffit forms hypotenuse.
The specific embodiment
As shown in Figure 1, a kind of hot bending glass that the present invention discloses, be to have hypotenuse 1 on arbitrary surface on glass arc limit, as shown in Figure 2, can be respectively to form a hypotenuse 1 on upper and lower surface, and for example shown in Figure 3, can be only to form a hypotenuse 1 at upper surface, perhaps as shown in Figure 4, can be only to form a hypotenuse 1 at soffit.
The glass that is used for hot bending can be monolithic glass, hollow glass or interlayer composite glass, and thickness is 5mm～25mm, and the width of corresponding hypotenuse is 5mm～100mm, and the width of the thick more hypotenuse 1 of glass is also wide more.
Because arbitrary surface on glass arc limit has hypotenuse 1, limit portion occurs and extrude and cause stress too concentrated so can overcome forming process, glass cracks, the defective of fracture phenomena thereby cause.Thereby can be applied in thicker hot bending glass, such as hollow glass and interlayer composite glass.
The concrete processing method of hot bending glass of the present invention is as follows:
Be used to make the raw material of hot bending glass earlier by product specification requirement cutting, again before heat-treating processing, the limit portion of desiring to curve the arc limit is carried out preliminary treatment, adopt wheel cutting, water cutting, laser cutting or grindings such as correct grinding, fine grinding, corase grind or chamfering, arbitrary Surface Machining on raw material glass arc limit is formed hypotenuse, the width of processing hypotenuse depends on the thickness of glass, the thick glass of 5mm～25mm in general, and the working width of hypotenuse is 5mm～100mm.Heat-treat processing through heating, brake forming, blowing (making glass strengthen stress), process for cooling successively then, obtain having the reinforcing glass product of the hot bending of certain radian after the processing, this reinforcing glass product stress can reach 20～250Mpa; Be that radian is 90 ° a product as shown in Figure 1.
Like this, with the cutting of arbitrary surface or the grinding formation hypotenuse on glass arc limit, purpose is to reduce the concentrated crackle that causes of stress of glass or break.The limit portion crooked position place that can reduce the little glass product of radius of curvature produces metaboly, can improve yield rate by the processing method that adopts above scheme.
