Description

Technical Field

[0001] This application relates to the field of glass manufacturing technology, and in particular to glass forming apparatus. Background Technology

[0002] Optical glass is a fundamental and essential component of the optoelectronic technology industry. With the continuous integration of optics with electronic information science and new materials science, the application of optical glass, as a basic optoelectronic material, in the three major fields of optical transmission, optical storage, and optoelectronic display has made rapid progress, becoming one of the fundamental conditions for the development of social informatization, especially optoelectronic information technology.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] In related technologies, glass forming apparatuses can be used to prepare optical glass. These apparatuses pour hot molten glass into a forming mold, where it cools and solidifies according to the mold's shape. However, these glass forming apparatuses cannot produce optical glass of varying thicknesses. Different glass forming apparatuses are required to prepare optical glass of different thicknesses, resulting in higher production costs.

[0050] To address the aforementioned problems, this application provides a glass forming apparatus that can be used to prepare glass of different thicknesses.

[0051] The following will combine Figures 1-4 The glass forming apparatus provided in the embodiments of this application will be described.

[0052] See Figure 1 This application provides a glass forming apparatus 100, which includes a plurality of driving structures 110. The plurality of driving structures 110 includes a first driving structure 110a and a second driving structure 110b arranged at intervals along a first direction A'. The plurality of driving structures 110 are used to drive a pressing structure 120 to move along a second direction B. For example, the second direction B can be parallel to the direction of gravity. The plurality of driving structures 110 are used to drive the pressing structure 120 to rise or fall.

[0053] See Figure 1 and Figure 2 The drive structure 110 includes a drive member 111, a mounting base 112, and a slider 113. The slider 113 includes a first sliding portion 1131 and a second sliding portion 1132 arranged and connected along the second direction B. The first sliding portion 1131 is movably disposed through the mounting base 112 along the second direction B. The drive end 1111 of the drive member 111 is connected to the first sliding portion 1131, and the drive member 111 is used to drive the slider 113 to reciprocate along the second direction B. The glass forming apparatus 100 includes a pressing structure 120, which is disposed on the side of the second sliding portion 1132 opposite to the first sliding portion 1131. The drive end 1111 of the drive member 111 can reciprocate along the second direction B to drive the slider 113 to move along the second direction B. The slider 113 is connected to the pressing structure 120, thereby driving the pressing structure 120 to reciprocate along the second direction B.

[0054] In some embodiments, the drive element 111 is a drive cylinder, which includes a cylinder barrel, a piston, and a piston rod. The piston is located inside the cylinder barrel, one end of the piston rod passes through the cylinder barrel and is connected to the piston, and the other end of the piston rod is located outside the cylinder barrel and is configured as the drive end 1111. The drive cylinder can be a pneumatic cylinder or a hydraulic cylinder.

[0055] Taking a cylinder as an example, the cylinder has a fast response speed, which can improve processing efficiency. The distance by which the cylinder drives the sliding member 113 to rise and fall along the second direction B can be a fixed value (for example, the maximum stroke of the piston rod). This reduces the difficulty of the cylinder controlling the rise and fall of the sliding member 113, and makes the force applied to the glass 200 by the pressing structure 120 more consistent in each operation, which is beneficial to improving the consistency of the glass product. When the cylinder drives the pressing structure 120 to fall, the cylinder applies pressure to the glass 200 through the pressing structure 120 to make the glass 200 more flat.

[0056] For example, the inner diameter of the cylinder is greater than or equal to 80mm, which makes the load-bearing capacity of the drive cylinder stronger and also facilitates the rapid upward movement of the pressure-pressing structure 120.

[0057] For example, the outer diameter of the piston along the radial direction of the piston rod is greater than or equal to 80 mm, and the outer diameter of the piston and the inner diameter of the cylinder are approximately the same. This makes the load-bearing capacity of the drive cylinder stronger and also facilitates the rapid upward movement of the pressing structure 120.

[0058] The following explains the calculation of the cylinder dimensions. Based on the total weight of the crossbeam 121 and the pressing component 122, combined with the frictional resistance, the thrust that the drive cylinder can provide is selected to be 307 kg ≈ 3014 N, and the cylinder working pressure P = 10. 5 Pa. According to the formula F=P×A, where F is the thrust, P is the working pressure, and A is the piston area of ​​the cylinder, substituting the data into the formula yields... Assuming the cylinder has a circular cross-section, the piston area A = πr 2 Transformed to: Substitute the data to obtain The cylinder bore diameter and piston area are calculated to be approximately 40mm*2=80mm. Therefore, based on the calculation, a cylinder with an inner diameter of 80mm is sufficient to meet the thrust requirement of 3014N.

[0059] See Figure 1 and Figure 2 The glass forming apparatus 100 may have a first direction A', a second direction B, and a third direction C, all of which are different. For example, the first direction A', the second direction B, and the third direction C may be perpendicular to each other. Exemplarily, the first direction A' may be the length direction of the glass forming apparatus 100, the second direction B may be the height direction of the glass forming apparatus 100, and the third direction C may be the width direction of the glass forming apparatus 100. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width may be greater than, equal to, or less than the length.

[0060] See Figure 1The glass forming apparatus 100 includes an adjusting member 130, which is disposed on the side of the pressing structure 120 facing the driving structure 110, and is located between the pressing structure 120 and the driving structure 110. The adjusting member 130 includes a first adjusting part 131 and a second adjusting part 132 arranged and connected along the second direction B. The first adjusting part 131 is detachably connected to the pressing structure 120, thereby facilitating the replacement and maintenance of the pressing structure 120. A groove 1133 is provided on the second sliding part 1132, and the second adjusting part 132 is located in the groove 1133. The outer wall of the second adjusting part 132 is threadedly connected to the groove wall of the groove 1133, thereby converting the rotational motion between the adjusting member 130 and the sliding part 113 into linear motion between the adjusting member 130 and the sliding part 113 along the second direction B. Thus, by removing the pressing structure 120 from the adjusting member 130, the adjusting member 130 can be rotated to rotate relative to the sliding member 113, thereby allowing the adjusting member 130 to move relative to the sliding member 113 along the second direction B, thus achieving the lifting and lowering of the adjusting member 130. Then, the pressing structure 120 is installed on the adjusting member 130, so that the pressing structure 120 is at the required horizontal height, and the distance between the pressing structure 120 and the bottom mold 153 after being driven down by the driving member 111 is at the required distance. This allows the glass forming apparatus 100 to produce glass 200 of the required thickness. By lifting and lowering the adjusting member 130, glass 200 of different thicknesses can be produced, improving the versatility of the glass forming apparatus 100 and reducing the cost of producing glass of different thicknesses.

[0061] For example, the first sliding part 1131 is located below the second sliding part 1132. The first adjusting part 131 is located above the second adjusting part 132.

[0062] For example, the adjusting element 130 can be a bolt or a screw.

[0063] In some embodiments, the pressing structure 120 and the adjusting member 130 can be detachably connected by bolts or screws.

[0064] In some embodiments, participants Figure 2 The drive end 1111 is connected to the sliding member 113 through the force transmission plate 115.

[0065] In some embodiments, participants Figure 1The mounting base 112 includes a linear bearing 1121 and a mounting base body 1122. The linear bearing 1121 is connected to the mounting base body 1122, and the sliding member 113 is movably inserted into the linear bearing 1121 along the second direction B. In this way, the linear bearing 1121 ensures that the sliding member 113 reciprocates along the second direction B in a straight line, while reducing friction and wear during the movement of the sliding member 113. It serves both a sealing function and a guiding function to ensure smooth operation and prevent wobbling, which helps to make the surface of the glass 200 flat and ensures the stable quality of the molded glass 200.

[0066] In some embodiments, participants Figure 1 The inner diameter of the linear bearing 1121 is greater than or equal to 40 mm. For example, the inner diameter of the linear bearing 1121 can be 40 mm, 41 mm, 42 mm or any value greater than 40 mm.

[0067] In some embodiments, the pressing structure 120 includes a crossbeam 121 and a pressing member 122. The pressing member 122 is located on the side of the crossbeam 121 facing the drive structure 110 and is connected to the crossbeam 121. The adjusting member 130 is detachably connected to the crossbeam 121. Thus, by providing the crossbeam 121, the weight of the pressing structure 120 can be increased, facilitating the application of pressure from the pressing structure 120 to the glass 200. This eliminates the need to make the pressing member 122 very large to increase the weight of the pressing structure 120, thereby reducing the manufacturing cost of the pressing member 122. The pressing member 122 is in direct contact with the glass 200, while the crossbeam 121 is not in contact with the glass 200. The material selection for the pressing member 122 is more stringent than that for the crossbeam 121, resulting in higher costs. Therefore, providing the crossbeam 121 helps to reduce costs.

[0068] In some embodiments, the dimension of the crossbeam 121 along the first direction A' is larger than the dimension of the pressing member 122 along the first direction A'. In this way, by setting the crossbeam 121, pressure can be applied to all parts of the pressing member 122 along the first direction A', which is beneficial to make the force on the pressing member 122 more balanced when pressing the glass 200.

[0069] In some embodiments, see Figure 3 The crossbeam 121 is provided with a plurality of weight-reducing holes 1211 arranged at intervals along the first direction A'. Since the crossbeam 121 has a large size along the first direction A', the crossbeam 121 has a large weight. By providing weight-reducing holes 1211, the crossbeam 121 can have the required weight while ensuring that it has a large size along the first direction A', thereby avoiding excessive pressure on the elastic buffer 114, allowing the elastic buffer 114 to recover, extending the service life of the elastic buffer 114, ensuring the continuity of operation of the glass forming device 100, and reducing downtime.

[0070] For example, without the weight reduction holes 1211, the total weight of the crossbeam 121 and the pressing component 122 reaches 120kg. By setting multiple weight reduction holes 1211 on the crossbeam 121, the total weight can be reduced to 90kg.

[0071] For example, the size of the pressing member 122 along the first direction A' is greater than the width of the glass 200 to be prepared. For example, the width of the glass 200 to be prepared can be 1200mm, and the size of the pressing member 122 along the first direction A' is greater than or equal to 1400mm, so that the pressing member 122 can press the glass 200 at various points along the first direction A', which is beneficial to improving the flatness of the glass 200.

[0072] For example, the dimension of the pressing member 122 along the third direction C is greater than or equal to 100 mm, so that the contact area between the pressing member 122 and the glass 200 is large, which is beneficial to applying pressure to the glass 200.

[0073] For example, the dimension (thickness of beam 121) of crossbeam 121 along the second direction B is greater than or equal to 50 mm. Thus, since beam 121 is relatively long, by setting the thickness of beam 121 to be relatively large, it is beneficial to prevent beam 121 from bending, thereby preventing the pressing member 122 from bending, which is beneficial to improving the flatness of glass 200.

[0074] For example, the dimension of the crossbeam 121 along the third direction C (the width of the crossbeam 121) is greater than or equal to 74mm. This makes the cross-sectional area of ​​the crossbeam 121 perpendicular to the first direction larger, which helps to prevent the crossbeam 121 from bending, thereby preventing the pressing member 122 from bending, and helping to improve the flatness of the glass 200.

[0075] For example, the crossbeam 121 has a dimension of 1900 mm or greater along the first direction A'. This is beneficial because the crossbeam 121 can apply pressure to all parts of the pressing member 122 along the first direction A', and the force on the pressing member 122 is more balanced when pressing the glass 200.

[0076] The following calculations are performed on the width and thickness of the crossbeam 121. The dimension of the crossbeam 121 along the first direction is 1900mm, the width of the crossbeam 121 is equal to half its thickness, and the cross section of the crossbeam 121 perpendicular to the first direction is rectangular. Under uniformly distributed load, the mid-span deflection f is calculated to be less than 1mm, for example, f = 0.5mm, and the total weight of the crossbeam 121 and the pressing component 122 is 130kg. The minimum moment of inertia I of the crossbeam is calculated to ensure that the deflection f of the crossbeam under uniformly distributed load does not exceed the allowable value of 0.5mm. The first step is to use the deflection formula for a simply supported beam under uniformly distributed load: To meet the deflection limit f≤0.5mm, the deformation is obtained. Substitute the data to get Where f = deflection (maximum bending deformation of the beam), q = uniformly distributed load intensity (load per unit length), L = span of the beam (dimension along the first direction A'), E = elastic modulus of the material, and I = moment of inertia of the cross section (a measure of the cross section's resistance to bending). The second step is to use the formula for the moment of inertia of a rectangular cross section: Where b is the width of beam 121 and h is the height of beam 121, b = h / 2, substituting the data yields... After substituting the data, we get: The minimum cross-sectional area of ​​beam 121 is calculated to be A = b * h = 76 * 38 = 2888 mm². 2 Based on the calculation results of the minimum cross-sectional area, in this embodiment of the application, the width of the beam 121 is set to 74mm and the thickness to 50mm. The rectangular cross-sectional area at this time is 74 * 50 = 3700mm². 2 Much larger than 2888mm 2 This makes the crossbeam 121 less prone to bending.

[0077] For example, the pressing frequency of the pressing structure 120 is less than or equal to 6 times / min. The pressing frequency can be the number of times the pressing structure 120 presses the glass 200 per minute. In this way, the frequency is low, and the contact time when the pressing structure 120 presses the glass 200 once can be set to be longer, which is beneficial to the forming of a wider glass 200.

[0078] For example, the total weight of the pressing structure 120 is greater than or equal to 90 kg, so that the pressing structure 120 can apply pressure to the glass 200.

[0079] In some embodiments, see Figure 4The pressing member 122 has a first cooling channel 1221 and a second cooling channel 1222. The pressing member 122 includes a first pressing portion and a second pressing portion arranged along a first direction A'. The first cooling channel 1221 penetrates the first pressing portion along the first direction A', and the second cooling channel 1222 penetrates the second pressing portion along the first direction A'. The first end of the first cooling channel 1221 and the second end of the second cooling channel 1222 are both located near the center of the pressing member 122 along the first direction A'. The first cooling channel 1221 and the second cooling channel 1222 are arranged at intervals along the first direction A'. The first end is the end of the first cooling channel 1221 facing the second cooling channel 1222. The second end is the end of the second cooling channel 1222 facing the first cooling channel 1221. The glass forming apparatus 100 includes a first air inlet pipe 141 and a second air inlet pipe 142. The air inlets of the first air inlet pipe 141 and the second air inlet pipe 142 are connected to an air source. The air outlet of the first air inlet pipe 141 is connected to a first end, and the air outlet of the second air inlet pipe 142 is connected to a second end. Thus, the cooling airflow is transmitted through the first air inlet pipe 141 and the second air inlet pipe 142 to the middle of the pressing member 122, and then transmitted to both ends of the pressing member 122 through the first cooling channel 1221 and the second cooling channel 1222. This improves the cooling effect on the pressing member 122 and prevents the pressing member 122 from sticking to the glass 200 and becoming difficult to separate.

[0080] In some embodiments, a first exhaust pipe 171 may be provided in the first cooling channel 1221, and a second exhaust pipe 172 may be provided in the second cooling channel 1222. The first exhaust pipe 171 and the second exhaust pipe 172 may extend out of the pressing member 122.

[0081] In some embodiments, see Figure 1 The glass forming apparatus 100 includes a forming mold 150, which has a forming groove 154 for supporting glass 200. The glass forming apparatus 100 is configured such that, in a pressing state, the forming mold 150 is located on the side of the pressing structure 120 facing the driving structure 110, and is located between the first driving structure 110a and the second driving structure 110b; the opening of the forming groove 154 faces the pressing structure 120 and is disposed opposite to the pressing structure 120 along a second direction B. The forming mold 150 includes a bottom mold 153, and a first side mold 151 and a second side mold 152 located at both ends of the bottom mold 153 along a first direction A'.

[0082] For example, the first side mold 151 and the second side mold 152 are provided with notches on the side opposite to the bottom mold 153. When the pressing member 122 presses the glass 200, the pressing member 122 can be located in the notch so that the pressing member 122 can contact the glass 200.

[0083] In some embodiments, the first side mold 151 and the second side mold 152 are detachably connected to the bottom mold 153. By replacing the first side mold 151 and the second side mold 152, the groove depth of the forming groove 154 formed by the first side mold 151, the second side mold 152, and the bottom mold 153 can be different, thereby enabling the preparation of glass 200 of different thicknesses. When the glass forming apparatus 100 prepares glass 200 of different thicknesses, the first side mold 151 and the second side mold 152 can be replaced, or the entire forming mold 150 can be replaced, so that the forming mold 150 can be adapted to glass 200 of different thicknesses. The embodiments of this application do not limit this.

[0084] In some embodiments, at least one of the first side mold 151 and the second side mold 152 can reciprocate relative to the bottom mold 153 along the first direction A'. Thus, the size of the forming groove 154 along the first direction A' can be adjusted by moving at least one of the first side mold 151 and the second side mold 152, thereby adapting it to forming glass 200 of different widths (size along the first direction A').

[0085] For example, the bottom mold 153 has a dimension of 1200 mm or more along the first direction A', so that it can be used to prepare glass 200 with a width of 1200 mm or more, thereby realizing the preparation of medical large screen monitoring glass 200.

[0086] For example, the outer diameter of the slider 113 along the direction perpendicular to the second direction B is greater than or equal to 40 mm, which helps to improve the mechanical strength of the slider 113 and its load-bearing capacity.

[0087] In some embodiments, the drive structure 110 further includes an elastic buffer 114. The mounting base 112 has a mounting space 1123, and the elastic buffer 114 is located in the mounting space 1123. A first sliding part 1131 extends into the mounting space 1123 and is connected to one end of the elastic buffer 114. The elastic buffer 114 is in a compressed state along the second direction B, and is used to provide elastic force to the sliding part along the direction from the first sliding part to the second sliding part. Thus, by providing the elastic buffer 114, when the drive member 111 drives the sliding part 113 to descend, the elastic buffer 114 can buffer the descent of the sliding part 113, making the descent speed of the sliding part 113 slower, so that the pressing member 122 slowly contacts the glass 200, which is beneficial to improving the stability of the pressing.

[0088] For example, the maximum elastic force of the elastic buffer 114 is greater than the total weight of the pressing structure 120. The maximum elastic force of the elastic buffer 114 is greater than or equal to 300 kg, so that the elastic buffer 114 can withstand the total weight of the pressing structure 120 and can also prevent the elastic buffer 114 from failing.

[0089] For example, the elastic buffer 114 includes a spring.

[0090] In some embodiments, the glass forming apparatus 100 includes a plurality of support structures 160, and the plurality of support structures 160 and a plurality of drive structures 110 are correspondingly arranged, with the drive structure 110 disposed on the top side of the corresponding support structure 160. For example, the support structures 160 and drive structures 110 are arranged in a one-to-one correspondence.

[0091] In some embodiments, in the corresponding support structure 160 and drive structure 110, the support structure 160 includes a support frame 161 and at least one support plate 162. The number of support plates 162 can be multiple, stacked along a second direction B, and located between the support frame 161 and the drive structure 110. The multiple support plates 162 may include a first support plate and a second support plate, located between the support frame 161 and the drive structure 110, stacked along the second direction B. The second support plate is located on the side of the first support plate facing the drive structure 110 and is connected to the drive structure 110. The first support plate is connected to the support frame 161, and the second support plate is movable relative to the first support plate along a third direction C. Thus, the first and second support plates have an active state. When the second support plate moves relative to the first support plate along the third direction C, it can drive the pressing structure 120 to move along the third direction C, thereby adjusting the position of the pressing structure 120 along the third direction C.

[0092] In some embodiments, the same support structure 160 includes multiple locking components for fixing the second support plate to the first support plate. The first support plate and the second support plate are connected by the locking components to form a locked state between the first support plate and the second support plate, which can prevent accidental relative movement between the first support plate and the second support plate in the locked state. The first support plate has multiple first through holes extending through it along a second direction B, and the second support plate has multiple second through holes extending through it along the second direction B. Any two of the first through holes, second through holes, and locking components are correspondingly provided. The first through holes and their corresponding second through holes are connected. At least one of the first through holes and their corresponding second through holes extends along a third direction C and is configured as a sliding hole. The locking component includes a first abutment, an insertion member, and a second abutment. When the first and second support plates are in a locked state, the first abutment abuts against the side of the first support plate opposite to the second support plate, and the second abutment abuts against the side of the second support plate opposite to the first support plate. The insertion member is inserted into the corresponding first and second through holes, and guides the movement direction of the second support member. The first and second abutments are used to clamp and fix the first and second support plates together. At least one of the first and second abutments is threadedly connected to the insertion member.

[0093] In some embodiments, in the same support structure 160, there are multiple sliding holes on the same one of the first support plate and the second support plate, and at least two sliding holes are arranged at intervals along the first direction, so as to prevent the first support plate and the second support plate from rotating relative to each other.

[0094] For example, the first abutment and the insertion part are constructed together as a bolt, and the second abutment is a nut. Tightening the nut onto the bolt can clamp and fix the first support plate and the second support plate to prevent them from moving accidentally in the locked state. After loosening the nut, the bolt and the strip-shaped sliding hole can move relative to each other to realize the relative movement of the first support plate and the second support plate.

[0095] In some embodiments, the glass forming apparatus 100 includes a controller and a solenoid valve. The controller is electrically connected to the solenoid valve, which controls the reciprocating motion of the piston of the drive cylinder along a second direction B. The controller controls the operation of the solenoid valve. Additionally, by setting parameters for the controller, the striking frequency (i.e., the striking frequency) of the striking structure 120 is controlled via the solenoid valve to adapt to the forming adjustments of different grades of glass 200.

[0096] For example, the working process of the glass forming device can be as follows: the solenoid valve controls the operation of the cylinder, and the piston rod of the cylinder drives the sliding part 113 to descend through the force transmission plate 115, thereby driving the pressing plate to press the top surface of the glass 200, assisting the glass 200 to widen and fill the bottom mold 153 to achieve a width of 1.2 meters, so that the top surface of the glass 200 is flat, meeting the flatness requirements of the subsequent cold processing of the glass 200. This glass forming device 100 can adjust the width and thickness of the glass 200 according to user needs to meet the production requirements of different specifications of glass 200. The glass forming device 100 can be used for the forming production of ultra-wide glass 200, with a daily output of 3-4 tons of glass. It has successfully produced 120 tons of qualified radiation-resistant wide glass, with a glass 200 forming qualification rate as high as 98%, demonstrating significant effectiveness.

[0097] For example, glass 200 can be optical glass, such as leaded glass.

[0098] In order to meet the requirements of forming ultra-wide glass 200, the glass forming apparatus 100 of this application embodiment has been redesigned and manufactured for the entire drive structure 110, pressing structure 120 and controller. Since the length of the pressing component 122 has been increased to at least 1400 mm, the length of the crossbeam 121 has been increased to at least 1900 mm, and the total weight of the crossbeam 121 and the pressing component 122 has been increased to at least 90 kg. After thrust calculation, the spring thrust has been increased to at least 300 kg, the cylinder inner diameter has been increased to at least 80 mm, and the diameter of the sliding component 113 has been increased to at least 40 mm.

[0099] For example, the glass forming apparatus can be used to produce leaded glass 200 with dimensions of 1500mm×1000mm×25mm / 30mm / 50mm or 2000mm×1200mm×25mm / 30mm. This application does not impose any limitations on these dimensions.

[0100] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
