The present invention arranges a plurality of mutually parallel main beams included in at least one of the lower part and the upper part of the forming section at an angle relative to the glass quenching process direction, and the rotation axis of the forming wheel installed on the lower part is perpendicular to the glass quenching process direction, so that during the quenching process, the glass bent into the single-curved arc surface moves linearly along the glass quenching process direction, that is, the outer diameter tangent direction of each forming wheel, thereby effectively preventing the glass bent into the single-curved arc surface from being exposed to the outside of the forming section and affecting the optical quality, thereby reducing the width and size of the forming section, which not only saves resources but also significantly reduces the requirements for the installation site, thereby facilitating large-scale promotion and use.

Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass production, and in particular to a device and method for producing single-curved arc-surface tempered glass based on straight-line movement. Background Art

[0002] Currently, the production method of single-curved arc tempered glass is mainly to heat the glass to the temperature required by the process and then transfer it to the forming and tempering section for cold quenching to obtain the product. If divided according to the process direction of the glass during cold quenching in the forming and tempering section, there are two methods: straight line and spiral.

[0003] The linear method is a widely used method. The forming and tempering section consists of a lower and upper section arranged opposite each other, each containing multiple parallel main beams, forming wheels attached to the main beams, and air nozzles. The main beams move in a linear direction parallel to the main beams during quenching after glass forming. Due to the presence of the main beams and the combined linear motion, the air nozzles cause inconsistent cooling and stress between the main beams and the main beam gaps on the glass, both in the normal projection of the glass. This results in severe wind spots on the tempered glass, seriously affecting the strength and optical quality of the tempered glass.

[0004] The spiral method was created to solve the problems of the linear method. For example, the Chinese invention patent CN107140814B discloses a device and method for producing tempered glass with a single curved arc surface. By setting a certain angle between the axis of the forming wheel and the axis of the main beam, and during the cold quenching process, the glass bent into the single curved arc surface has a spiral trajectory relative to the single curved arc surface composed of the outer diameter generatrix of each forming wheel. This method effectively solves the current problem of severe wind spots on tempered glass with single-curved arc surfaces and improves the optical quality of the product. However, the following technical problems exist during the implementation of this patent: since a certain angle is set between the axis of the forming wheel and the axis of the main beam, the movement trajectory of the glass bent into a single-curved arc surface relative to the single-curved arc surface composed of the outer diameter generatrix of each forming wheel is a spiral line. Therefore, the glass bent into a single-curved arc surface will continuously swing left and right in the walking direction perpendicular to the production process during the movement. In order to prevent the glass bent into a single-curved arc surface from being exposed to the outside of the forming section and affecting the optical quality, it is necessary to increase the effective width and size of the forming section, and thereby increase the effective width of the heating furnace and the loading and unloading device. This not only causes a waste of effective equipment resources, but also increases the equipment's own cost and operating cost, and increases the requirements for its installation site, which is not conducive to its large-scale use. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a single-curved arc surface tempered glass production device and method based on straight-line walking.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a single-curved arc surface tempered glass production device based on straight-line travel includes a heating section and a forming section, wherein the forming section is composed of a lower part and an upper part arranged opposite to each other, wherein the lower part of the forming section includes multiple mutually parallel main beams, multiple blowing nozzles, multiple forming wheels and their transmission system, multiple forming wheels and blowing nozzles are all installed on the main beams, and the blowing nozzles face the glass; the surface formed by the outer diameter generatrix of the multiple forming wheels can be unfolded into a plane or a continuous curved surface, or bent into a single-curved arc surface with the axis parallel to the direction of the glass quenching process; all the forming wheels rotate synchronously and at the same speed; the upper part of the forming section includes multiple mutually parallel main beams and multiple blowing nozzles, and the blowing nozzles are installed on the main beams and face the glass;

[0007] At least one of the lower and upper parts of the forming section includes multiple parallel main beams that are inclined relative to the direction of the glass quenching process, and the rotation axis of the forming wheel installed on the lower part is perpendicular to the direction of the glass quenching process.

[0008] Preferably, the multiple mutually parallel main beams included in the lower part of the forming section are arranged obliquely relative to the direction of the glass quenching process, and the inclination angle A is an acute angle.

[0009] Alternatively, the upper portion of the forming section includes a plurality of mutually parallel main beams that are arranged tilted relative to the glass quenching process direction, and the tilt angle B is an acute angle.

[0010] Alternatively, the multiple mutually parallel main beams included in the lower part and the upper part of the forming section are all inclined relative to the direction of the glass quenching process, with inclination angles A and B respectively, and both are acute angles.

[0011] Furthermore, the inclination angle A is equal to the inclination angle B.

[0012] Furthermore, both ends of the plurality of mutually parallel main beams are fixedly connected via hinged connecting plates.

[0013] Furthermore, the forming wheels and the blowing nozzles installed on the same main beam are staggered, and the forming wheels are installed on the main beam at equal distances.

[0014] The production method of the single-curved arc surface tempered glass production device based on straight-line travel of the present invention includes the following steps:

[0015] Heating process: The glass is heated to the temperature required by the process in the heating section, softened, and then sent out;

[0016] Transfer process: The outer diameter generatrix of each forming wheel in the forming and tempering section forms a horizontal plane or a continuous curved surface, which transfers the glass into the glass;

[0017] Forming process: The horizontal plane or continuous curved surface formed by the outer diameter generatrix of each forming wheel in the forming tempering section is bent into a single curved arc surface. The heated and softened glass is bent into a single curved arc surface by gravity against the forming wheel.

[0018] Cold quenching process: The glass bent into a single arc surface moves continuously relative to the single arc surface formed by the outer diameter generatrix of each forming wheel, while the blowing nozzles on the upper and lower surfaces blow air to quench the glass until the tempering is completed;

[0019] During the quenching process, the glass bent into a single curved arc surface moves linearly along the direction of the glass quenching process.

[0020] Furthermore, the glass bent into a single curved arc surface performs reciprocating motion along the direction of the glass quenching process.

[0021] Furthermore, the glass bent into the single-curved arc surface performs unidirectional movement along the direction of the glass quenching process.

[0022] Compared with the prior art, the beneficial effect of the present invention is as follows: the present invention tilts the multiple parallel main beams included in at least one of the lower part and the upper part of the forming section relative to the direction of the glass quenching process, and the rotation axis of the forming wheel installed on the lower part is perpendicular to the direction of the glass quenching process, so that during the quenching process, the glass bent into a single-curved arc surface moves in a straight line along the direction of the glass quenching process, that is, the tangent direction of the outer diameter of each forming wheel, thereby effectively preventing the glass bent into a single-curved arc surface from being exposed to the outside of the forming section and affecting the optical quality, and further reducing the width and size of the forming section, which not only saves resources, but also significantly reduces the requirements for the installation site, which is conducive to large-scale promotion and use.
