Description

[0002] With the rapid development of social industrialization, glass is increasingly used in contemporary applications, especially in decorative walls, buildings, balconies and furniture, and is favored for its beautiful visual effects. Generally speaking, glass is softened by heating and then formed in a mold, and then annealed to make flat glass. With the increasing demand, people's requirements for glass quality are also increasing. The production process of flat glass into curved glass mainly includes three key steps: heating, bending and cooling. First, the flat glass is heated to a certain temperature to make it soft, usually heated to the softening point or slightly higher. Then, the heated glass is bent using a bending mold or mechanical equipment to form the desired arc. The temperature and time need to be controlled during the bending process to ensure that there are no bubbles or cracks on the glass surface. Finally, the bent glass enters the cooling system and gradually cools to room temperature to ensure its strength and shape stability.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0041] See also Figure 1-Figure 8 As shown, the present invention discloses a forming device for glass processing, comprising an upper arc changing component 1, a lower arc changing component 2, and a chassis 5 located at the upper and lower sides of the glass, the chassis 5 is provided with an edge pulling component 3 for pulling the upper arc changing component 1 and the lower arc changing component 2 to deform and bend, and the upper arc changing component 1 and the lower arc changing component 2 are both provided with an air flow distribution component 7 for controlling the glass temperature;

[0042] The chassis 5 is used to adjust the distance between the upper arc changing component 1 and the lower arc changing component 2. The chassis 5 is provided with an inner pulling component 8 for pulling the middle section of the lower arc changing component 2, that is, when the lower arc changing component 2 is pulled, the middle section of the lower arc changing component 2 is pulled by the inner pulling component 8, and the edge section of the lower arc changing component 2 can be pulled by the side pulling component 3 on the lower arc changing component 2. The upper arc changing component 1 and the lower arc changing component 2 are symmetrically arranged, and the upper arc changing component 1 and the lower arc changing component 2 have the same structure. The lower arc changing component 2 includes a plurality of arc changing units 201. Since there are a plurality of arc changing units 201, the structure of the arc changing unit 201 is specifically that the arc changing unit 201 is The "T" shape as a whole includes a vertical end and a horizontal end, the vertical end is connected to one side of the length midline of the horizontal end, preferably, the vertical end is in a strip or trapezoidal structure, and the large end is connected to the horizontal end, and a strip groove 202 is provided on the vertical end of the arc changing unit 201, and the strip groove 202 extends along the vertical end of the arc changing unit 201, and the distal end of the vertical end of the arc changing unit 201 is rotatably provided with a connecting arm 203, that is, the connecting arm 203 is arranged away from the horizontal end, and the movable end of the connecting arm 203 is rotatably connected with a rotating pin, and the rotating pin is clearance-matched with the strip groove 202 on the adjacent arc changing unit 201. When the entire arc changing unit 201 rotates, the rotating pin is in the strip groove 20 2 internal sliding, can assist multiple arc changing units 201 to rotate in the same plane, so as to reduce the error in the horizontal direction when the arc changing unit 201 rotates. Further, both ends of the horizontal end of the arc changing unit 201 are rotatably connected with side rollers 204, and the side rollers 204 are used to assist the connection of two adjacent arc changing units 201. Further, a pulling spring 205 is connected between two adjacent arc changing units 201, and the pulling spring 205 forms a pulling force between the two adjacent arc changing units 201. When the upper arc changing component 1 and the lower arc changing component 2 are in operation, they will be affected by factors such as wind force and mechanical vibration. The use of the pulling spring 205 with a reasonable elastic coefficient , which can reduce the transmission of vibrations. The pulling spring 205 can absorb and alleviate these vibrations, reduce the vibration transmission between adjacent T-shaped plates, and thus improve the stability of the overall structure; at the same time, the pulling spring 205 can avoid the gap between two adjacent arc-changing units 201 being too large or too small due to changes in external forces, maintain a reasonable spacing of the structure, make the stress distribution between adjacent T-shaped plates more uniform, avoid local stress concentration, and reduce the risk of deformation or cracking of the plate; along with the overall dynamic response capability of the glass processing wind grid system, the ability to resist impact and vibration is enhanced, thereby ensuring the long-term stable operation of the system.

[0043] When counting, see Figure 7As shown, the following arc changing component 2 is used as a reference for counting. When the number of arc changing units 201 is an odd number, the midline of the arc changing unit 201 located in the middle is used as a reference 0 to start counting, and the position where the edge roller 204 appears is used for counting. The counts of the edge roller 204 located on the right side of the midline of the arc changing unit 201 are: 1, 2, 3...k-2, k-1, k...n-2, n-1, n, and the counts of the edge roller 204 located on the left side of the right side of the midline of the arc changing unit 201 are: -1, -2, -3...-(k-2), -(k-1), -k...-(n-2), -(n-1), -n, wherein k is greater than or equal to 4, and n is greater than or equal to 7;

[0044] When the number of the arc changing units 201 is an even number, the position located in the middle of all the arc changing units 201 is the edge roller 204 between two arc changing units 201, and the counting is performed with the count of the edge roller 204 being 0. The counts of the edge roller 204 located on the right side of the edge roller 204 are: 1, 2, 3...k-2, k-1, k...n-2, n-1, n, and the counts of the edge roller 204 located on the left side of the edge roller 204 are: -1, -2, -3...-(k-2), -(k-1), -k...-(n-2), -(n-1), -n, wherein k is greater than or equal to 4, and n is greater than or equal to 7;

[0045] Then in the wind grid system, the middle section of the lower arc changing component 2 mainly refers to the part of the arc changing unit 201 between -k and k, that is, the inner pulling component 8 is mainly used to pull the part of the arc changing unit 201 between -k and k, to assist the lower arc changing component 2 in deformation support, maintain the stable connection between the arc changing units 201, avoid the structure from loosening or deformation due to wind or external impact, share the external force on each part of the wind grid, and maintain its overall stability, thereby reducing the difference in arc diameter between the middle position and the edge position of the arc changing unit 201 in the lower arc changing component 2 during the deformation process. At the same time, since the airflow distribution component 7 is required for airflow distribution during the overall use of the device, the use of the inner pulling component 8 can also reduce the impact of uneven wind force or load on the lower arc changing component 2, reduce the transition deformation between the middle section arc changing units 201, and improve the wind resistance of the middle section arc changing units 201. In addition, during the use of the device, the load distribution is adjusted, and the overall seismic resistance of the lower arc changing component 2 can be enhanced by pulling the inner pulling component 8.

[0046] The chassis 5 is provided with a stopper assembly 6 for locking and positioning the side pulling assembly 3 and the inner pulling assembly 8. When the device is in use, the glass can be conveyed between the upper arc changing assembly 1 and the lower arc changing assembly 2 through the front conveying equipment, and high-pressure gas is blown toward the upper and lower surfaces of the glass through 7 to keep the glass in a higher temperature range so that the glass is more easily deformed at high temperatures; when the glass is being shaped, high-pressure gas with a lower temperature is blown toward the upper and lower surfaces of the glass through 7 to assist in shaping the glass; the two sets of side pulling assemblies 3 on the chassis 5 can be used to pull and set the edge positions of the upper arc changing assembly 1 and the lower arc changing assembly 2 respectively, and when the side pulling assemblies 3 are pulled, the glass is kept in a higher temperature range. After pulling, the arc changing mechanism 1 and the lower arc changing component 2 form a concave arc frame structure, and cooperate with the inner pulling component 8 to support the middle section of the lower arc changing component 2, so that the entire lower arc changing component forms an arc surface structure, increasing the supporting force of the lower arc changing component 2. This pulling force ensures that the glass can bend or deform within an appropriate range, making the arc changing structure more uniform and stable; the stopper component 6 can be used to lock and position the side pulling component 3 and the inner pulling component 8, ensuring that the side pulling component 3 and the inner pulling component 8 accurately position the upper pulling component 1 and the lower pulling component 2 in an arc angle, making the operation more precise and avoiding looseness during the pulling process;Since the arc changing units 201 are connected mainly by the rotation of the side rollers 204 to connect the two adjacent arc changing units 201, there will be gaps and incomplete alignment at the connection positions. Since the upper arc changing assembly 1 and the lower arc changing assembly 2 both contain multiple arc changing units 201, during the pulling process, the connection of the multiple arc changing units 201 will cause the connection errors to be transmitted and accumulated between the multiple arc changing units 201. As the number of arc changing units increases, the cumulative effect of the errors may cause the final arc deformation of the glass to be uneven, affecting the product quality. However, in the present device, the adjacent arc changing units 201 are connected by the pulling springs 205, and the pulling springs 205 can be used to pull the two adjacent arc changing units 201. For example, when the connection between the arc changing units 201 is not tight, the elastic characteristics of the pulling springs 205 themselves can be used to compensate for the errors of the two adjacent arc changing units 201, thereby avoiding The buffering effect of the pulling spring 205 can absorb and alleviate the external impact force when the upper arc changing component 1 and the lower arc changing component 2 are deformed, thereby forming a more stable arc structure, thereby supporting the deformation process of the glass and avoiding drastic fluctuations or excessive deformation. In a preferred embodiment, the arc changing unit 201 at the middle section can use a pulling spring 205 with a higher elastic coefficient, and the edge position close to the arc changing unit 201 can use a pulling spring 205 with a slightly lower elastic coefficient, that is, the elastic coefficient of the pulling spring 205 at the middle section is greater than the elastic coefficient of the pulling spring 205 at the edge position. The pulling spring 205 can effectively compensate for the connection error between the arc changing units 201 through its elastic force and adjustment function, maintain the uniform distribution of the pulling force, absorb external vibration and impact, and avoid excessive deformation, thereby ensuring the deformation accuracy of the glass. ;

[0047] The chassis 5 includes an upper box body 501 and a lower box body 503. When the device is installed, the upper box body 501 can be fixedly installed. The upper box body 501 is used to fix the side pulling component 3 on the upper arc changing component 1, and the lower box body 503 is used to fix the side pulling component 3 and the inner pulling component 8 on the lower arc changing component 2. The upper box body 501 and the lower box body 503 are connected by a telescopic cylinder 502. When the telescopic cylinder is extended, the distance between the upper box body 501 and the lower box body 503 increases, and the distance between the upper box body 501 and the lower box body 503 can be adjusted. The telescopic cylinder 502 is electrically connected to the controller, and the telescopic cylinder can be controlled by the controller, so that the overall operation of the device is simpler and more convenient.

[0048] Furthermore, the side pulling assembly 3 includes a side pulling belt 301 and a plurality of side winding rollers 302 located inside the chassis 5. The width of the side pulling belt 301 and the inner pulling belt 804 is greater than or equal to 50 mm, which can greatly improve the pulling force of the side pulling belt 301. The inside of the chassis 5 is connected to a bracket plate 304 through a side thrust cylinder 305. The side thrust cylinder 305 is electrically connected to the controller. The side pulling belt 301 serves as the main load-bearing component of the entire side pulling assembly 3 and is responsible for bearing and transmitting the pulling force. When connecting, the side pulling belt 301 bypasses the nth side roller 204 and is sequentially connected to no less than n-2 side rollers 204 located on the inner side, where n is greater than or equal to 7. When connecting with the side roller 204, see Figure 3 As shown, a fixing ring 306 is provided on the arc changing unit 201 corresponding to the edge roller 204. Preferably, the fixing ring 306 is located on the outer side of the edge roller 204. The outer side of the fixing ring 306 realizes the connection between the edge pulling belt 301 and the fixing ring 306 through a fixing clip 307, thereby realizing the connection between the edge pulling belt 301 and the edge roller 204. After the connection, the rotation of the edge roller 204 will not be affected. When connecting, the edge pulling belt 301 is connected to no less than three edge rollers 204 near the edge position, ensuring the pulling force. The side pulling belt 301 is evenly distributed. In the pulling structure of the side pulling belt 301, the movable end of the side pulling belt 301 extends upward and passes through a plurality of side winding rollers 302 in sequence. The side winding roller 302 is an axial structure. Both ends of the axial structure are rotatably connected to the chassis 5. The axial structure of the side winding roller 302 is provided with an annular guide groove 302a corresponding to the side pulling belt 302, which is used to limit the side winding roller 302. Preferably, the outer wall of the annular guide groove 302a is provided with a slot, and the inner wall of the side pulling belt 301 is provided with an insert corresponding to the slot to ensure The side pulling belt 301 is pulled more smoothly on the inner side of the annular guide groove 302a, and after the side winding roller 302 is locked by the stop assembly 6, the fixing effect of the side pulling belt 3010 can be guaranteed. The movable end of the side pulling belt 302 is fixedly connected to the bracket plate 304, and the side pulling belt 301 located at the four corners of the length and width of the lower arc changing assembly 2 can be fixed by the bracket plate 304. When the side thrust cylinder 305 is extended or shortened, the side thrust cylinder 305 is pushed to move up and down, and the side pulling belt 301 can be The outer sides of the plurality of side winding rollers 302 are driven to pull the side rollers 204 to achieve deformation adjustment of the arc changing unit 201. Since there are a large number of side winding rollers 302, the installation of the side pulling belt 301 can be assisted by the upper and lower rows of staggered side winding rollers 302. Furthermore, the bottom end of the side thrust cylinder 305 on the upper arc changing assembly 1 is fixedly connected to the bracket plate 304 for pulling the lower arc changing assembly 2, and the upper arc changing assembly 1 and the lower arc changing assembly 2 can be supported respectively by the two variable pulling assemblies 3;

[0049] In the structure of the air flow distribution component 7 for heating and supplying air to the glass, the air flow distribution component 7 includes an air duct 702 with an air outlet 701, the air duct extends along the length direction of the edge roller 204, the air inlet end of the air duct 702 is connected to the air inlet control module, and an air pressure temperature sensor module 703 is arranged in the air duct 702, the air pressure temperature sensor module 703 is used to monitor the air pressure and temperature inside the air duct 702, the air pressure temperature sensor module 703 and the air inlet control module are both electrically connected to the controller; in actual operation, the temperature inside the air duct 702 is monitored by the air pressure temperature sensor 703, the air inlet control module is controlled by the controller to control the air inlet, and the hot air is guided to the surface of the glass through the air outlet 701 to assist the glass in molding, wherein the air inlet control module includes a corresponding air inlet valve, an air inlet channel, and a heating gas storage structure, and the temperature and deformation of the glass are controlled by controlling the air inlet valve and the heating gas;

[0050] Furthermore, a middle roller 206 is provided at the position where the horizontal part and the vertical part of the arc-changing unit 201 are connected. The middle roller 206 is elliptical, and its long side corresponds to the horizontal end of the arc-changing unit 201. The middle roller 206 with an elliptical outer wall can guide the wind, reduce the loss of hot wind, and make the wind blow closer to the glass surface. Furthermore, the middle roller 206 is made of a heat-insulating material;

[0051] In the structure of the inner pulling component 8, the inner pulling component 8 includes an inner pulling belt 804 and an inner belt winding roller 803 rotatably connected to the chassis 5. The chassis 5 is connected to a fixed shaft 802 through an inner thrust cylinder 801. The inner thrust cylinder 801 is electrically connected to the controller. The bottom end of the inner pulling belt 804 passes around the kth side roller 204 and is sequentially connected to no less than k-2 side rollers 204 located on the inner side thereof, where k is greater than or equal to 4. The connection method used when connecting the inner pulling belt 804 and the side roller 204 is consistent with the connection method of the side pulling belt 301 and the roller 204, see Figure 8 As shown, guide grooves 302a corresponding to the inner pulling belts 804 are provided on the inner winding rollers 803. When operating, the inner thrust cylinder 801 is extended to pull the inner pulling belts 804 to rotate outside the multiple inner winding rollers 803, thereby synchronously pulling the arc changing units 201 on both sides to rotate. Furthermore, after the inner thrust cylinder 801 is shortened, the arc changing unit 201 can be reset.

[0052] The side pulling belt 301 between the side winding rollers 302 and the inner pulling belt 804 between the inner winding rollers 803 are transmission belts. The chassis 5 is provided with a pressure sensing module 9 corresponding to the transmission belt. The pressure sensor 9 can detect whether the transmission belt position is in a tensioned state. Since the distance between the axes of the two side winding rollers 302 and the two inner winding rollers 803 is relatively stable, that is, when the transmission belt is in a tensioned state, a larger value appears on the pressure sensor 9. When all the pressure sensors 9 are in the above state, it means that the section of the transmission belt is in a stressed state. The monitoring value of the pressure sensor 9 can be used to feed back the auxiliary controller to control the airflow distribution component 7 to work, which can save more high-pressure gas energy transported in the airflow distribution component 7 and has higher thermal energy efficiency.

[0053] When using the device, the chassis 5 can be used to make the lower arc-changing component 2 close to the upper arc-changing component 1, and the airflow distribution component 7 can assist in softening the glass. The length is adjusted by the side thrust cylinder 305 corresponding to the upper arc-changing component 1, and the side pulling belt 301 is used to pull the arc-changing unit 201 at the edge of the upper arc-changing component 1 along with the rotation of the side belt roller 302 to complete the deformation of the upper arc-changing component 1, and the side thrust cylinder 305 corresponding to the lower arc-changing component 2 and the internal thrust cylinder 801 assist the lower arc-changing component 2 to perform arc deformation, so as to achieve precise adjustment of the angles of the upper arc-changing component 1 and the lower arc-changing component 2; complete the overall adjustment of the device, and through the stop component 6, the internal pulling component 8 and the locking of the two groups of side pulling components 3, the angle of the upper arc-changing component 1 and the lower arc-changing component 2 is fixed, so as to assist the glass in shaping processing, and the processing effect is good.

[0054] In the pulling process of the upper pulling component 1 and the lower pulling component 2, since the connection between the fixing rings 306 is realized by the fixing card 307, the connection between the side pulling belt 301 and the fixing ring 306, and the connection between the inner pulling belt 804 and the fixing ring 306 are realized. Taking one group as an example, since the side pulling belt 301 is in a straight line state when directly connecting the two fixing rings 306, and since the side pulling belt 301 is not connected to the axial position of the fixing ring 306, when the arc unit 201 is pulled to the arc state by the side pulling belt 301, that is, when the side pulling belt 301 is in a tensioned state, the side pulling belt 301 close to 306 is pulled. 01 is in a state of being close to 306, thereby causing the side pulling belt 301 between the pulling fixing ring 306 to be in an over-tight state, then the side pulling belt 301 connected between the multiple arc changing units 201 can straighten these arc changing units 201, and all of them are in a nearly straight line state with a small curvature, and cooperate with the pulling spring 205 to correct the angle between two adjacent arc changing units 201, so that the angle of the arc changing unit 201 in the tensioned state can be adjusted at a smaller angle. After the adjustment is completed, the situation where the angle between the arc changing units 201 in the non-pulling state is larger and the angle of the arc changing units 201 in the pulling state is smaller will still exist , so there will be an angle difference. In order to further avoid the above difference, a corresponding adjustment structure is set on the arc changing unit 201: the length of 301 located between the two fixing rings 306 is greater than the distance between the two adjacent fixing cards 307, and an electric screw 308 and a support block 309 are arranged on the outside of the arc changing unit 201. The electric screw 308 is provided with a motor to control its rotation. The motor is electrically connected to the controller, and the motor can be controlled by the controller to work. The motor drives the electric screw 308 to rotate. The support block 309 is threadedly connected to the movable end of the electric screw 308, and the support block 309 is slidably matched with the arc changing unit 201. To achieve a guiding effect on the support block 309, when the electric screw 308 rotates, the electric screw 308 drives the support block 309 to move up and down, and the movable end of the support block 309 corresponds to the side pulling belt 301 or the inner pulling belt 804. The support block 309 is used to support the side pulling belt 301, so as to adjust the tightness of the side pulling belt 301 between the two fixed rings 306. When the side pulling belt 301 pulls the arc-changing unit 201 into an arc shape, the side pulling belts 301 with different tightness can achieve arc-shaped pulling between multiple arc-changing units 201 without affecting the pulling effect of the arc-changing unit 201.

In the device, after the upper arc-changing component 1 and the lower arc-changing component 2 are arc-changed, the lowest point of the upper arc-changing component 1 is located at the position of the arc-changing unit 201 in the middle. After the arc-changing unit 201 in the middle is pulled by the height-adjusting component 4, it is beneficial to form the overall alignment of the device. In the structure of the height component 4, the height adjustment component 4 includes a connecting frame 401 connected to the arc changing unit 201 in the middle of the upper arc changing component 1, and the connecting frame 401 is an inverted "L"-shaped structure, wherein the vertical end is connected to the arc changing unit 201 located in the middle, and the horizontal end thereof extends horizontally, and also includes a fixedly arranged door-shaped frame, the top surface of the door-shaped frame is located above the upper arc changing component 1, and the top surface of the door-shaped frame is connected to a threaded rod 402, and the threaded rod 402 extends longitudinally, and the threaded rod 402 passes through the horizontal end of the connecting frame 401 A through hole, a threaded rod 402 passes through the through hole, and the outer side of the threaded rod 402 is threadedly connected to the nuts located at the upper and lower parts of the horizontal end of the connecting frame 401.

Further, a longitudinal extension groove is provided on the threaded rod 402, and the groove body faces one side of the device, and a scale mark for indicating the height of the threaded rod 401 is provided on the inner side of the longitudinal extension groove. Further, the two connecting frames 401 located in the width direction of the upper arc changing component 1 form a "door" shape structure. In addition, preferably, a horizontal monitoring module is provided on the horizontal end face of the connecting frame 401, so that when the height of the upper arc changing component 1 is adjusted, the arc changing units 201 located on both sides of the width are adjusted to a horizontal state through the horizontal detection module, thereby ensuring the horizontal state of the arc changing units 201. The horizontal monitoring module is a level bubble or an electronic level.

After the electromagnet 605 is energized, it can absorb the iron moving rod 604, drive the moving rod 604 to overcome the elasticity of the thrust spring 603 and slide toward the electromagnet 605, thereby releasing the locking and fixing of the plug 602 to the slot ring 601. In a preferred embodiment, a displacement sensor is provided on the outer wall of the moving rod 604, and the displacement sensor and the electromagnet 605 are both electrically connected to the controller.
