Abstract
The invention belongs to material processing technique, and relates to a moulding method for a piece of organic glass. In a moulding method for an organic glass large-curved-surface windshield, CATIA software is utilized to analyze a curved surface of a product, and a tool corresponding to a female frame moulding method is designed. In a product moulding process, a numerical control processing method is utilized to perform pre-cutting treatment at positions, where materials are easy to be piled due to a conventional rolling process, so that problems of wrinkles and accumulation of raw materials in an upper mold rolling process in a moulding process are prevented. A mold is heated at a low temperature; the conventional rolling method is used; time of cooling the raw materials is shortened in the moulding process; and product processing becomes convenient to workers in the production line. The shape and curved surface of the product are ensured.
Description
Technical field
The invention belongs to materials processing technology, relate to a kind of lucite forming method.
Background technology
The problem that large curved surface windshield is produced difficulty and cannot be produced.In the ordinary course of things, traditional cloudy frame forming method, because of the impact of environment, temperature, makes large-scale bi-curved lucite cannot be shaping, and windshield is for the requirement of product thickness, optical distortion, general forming method is the shaping of the windshield that cannot meet large curved surface.
Summary of the invention
The present invention seeks to: in order to the problem of difficulty cannot be produced and produce to large curved surface windshield.Meet company's scientific research and batch demand of producing, enhance productivity, reduce costs.
Technical solution of the present invention is: propose a kind of lucite forming method, CATIA software is used to analyze product curved surface, design the frock of the corresponding cloudy frame method of forming, formed product utilize numerical-control processing method to prolong for tradition platen press is shaping causes easy windrow place to carry out cutting process in advance, prevent patrix in material forming process from prolonging the problem of the fold pressed through in journey, accumulation.And by carrying out low-temperature heat to mould, use traditional pressure method of prolonging shaping, reduce the time of the raw material cooling in forming process, facilitate worker at the production line for the processing process of product.Ensure profile and the curved surface of product.
A kind of lucite large curved surface windscreen forming method, comprises the following steps:
The first step, according to the digital-to-analogue of product, designs cloudy frame shaping mould, and require mould to ensure the summit at product four angles is on a horizontal plane as far as possible;
Second step, on aerial organic glass raw material, under go out the square stock of shaping mould size, with three-dimensional software, the digital-to-analogue of product is launched, obtains the shape of product paved, then square stock is excised into: the shape of product paved adds the edge of 25mm-30mm;
3rd step, after heating the material cut, take out, be layered on cloudy frame shaping mould, cloudy frame shaping mould should heat in advance; Material is flattened on cloudy frame shaping mould, cuts out windshield along cloudy frame shaping mould, cooling;
In 3rd step, expect that the temperature carrying out heating is determined by the thickness of glass.
Advantage of the present invention is: can carry out under general glass ware forming environment, method breaches hyperboloid lucite and uses and traditional prolong the key technologies such as platen press difficult forming, the optical property of both having possessed traditional cloudy frame shaped article is better, and has thickness evenly to wait technical characterstic
Accompanying drawing explanation
Fig. 1 is certain windshield product digital-to-analogue X-Y scheme in embodiment;
Fig. 2 is certain windshield product digital-to-analogue planar development plane configuration in embodiment.
Fig. 3 is that in embodiment, material is flattened form on cloudy frame shaping mould by certain windshield product.
Detailed description of the invention
Below the present invention is described in further details.
The first step, according to the digital-to-analogue of product, designs cloudy frame shaping mould, and require mould to ensure the summit at product four angles is on a horizontal plane as far as possible; Need in die design process to consider that human body is easy to operate, be convenient to worker at the production line and in forming process, product processed.
Second step, on aerial organic glass raw material, under go out the square stock of shaping mould size, with three-dimensional software, the digital-to-analogue of product is launched, obtains the shape of product paved, then square stock is excised into: the shape of product paved adds the edge of 25mm-30mm; Solve patrix in forming process and prolong the problem of the fold pressed through in journey, accumulation.
3rd step, after heating the material cut, take out, be layered on cloudy frame shaping mould, cloudy frame shaping mould should heat in advance; Material is flattened on cloudy frame shaping mould, cuts out windshield along cloudy frame shaping mould, cooling.The low-temperature heat of mould reduces the time of the raw material cooling in forming process, facilitates worker at the production line for the processing process of product.Ensure profile and the curved surface of product.
Embodiment
Produce as example with certain windshield below.
Diagram 1 is certain windshield product.
The first step, analyzes this windshield digital-to-analogue, and planar development determination windshield plane configuration (as illustrated 2), blanking relaxes 30mm at the state lower limb of paving.
Second step, puts into glass pot arch and heats by spread material, heating-up temperature 150 °, constant temperature 15 minutes.
3rd step, heating mould, product mold heats under being placed in infrared lamp assembly, uses infrared temperature-measuring gun testing mould surface temperature, stops heating, remove infrared lamp component devices when temperature reaches 65 °.
4th step, takes out spread material and is laid in shaping mould, press box on compression mould from pot arch, (as illustrated 3), the manual mould of being fitted by inner plane of operative employee.
5th step, is cooled to normal temperature, takes out product, carries out the protection of subsides mould to product.
Claims (2)
1. a lucite large curved surface windscreen forming method, is characterized in that, comprise the following steps:
The first step, according to the digital-to-analogue of product, designs cloudy frame shaping mould, and require mould to ensure the summit at product four angles is on a horizontal plane as far as possible;
Second step, on aerial organic glass raw material, under go out the square stock of shaping mould size, with three-dimensional software, the digital-to-analogue of product is launched, obtains the shape of product paved, then square stock is excised into: the shape of product paved adds the edge of 25mm-30mm;
3rd step, after heating the material cut, take out, be layered on cloudy frame shaping mould, cloudy frame shaping mould should heat in advance; Material is flattened on cloudy frame shaping mould, cuts out windshield along cloudy frame shaping mould, cooling.
2. a kind of lucite large curved surface windscreen forming method as claimed in claim 1, is characterized in that, in the 3rd step, expects that the temperature carrying out heating is determined by the thickness of glass.
