Description

Technical Field

[0001] The invention relates to the technical field of glass reforming, in particular to a device for gradually reforming bent tempered glass. Background Art

[0002] Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to transfer the softened glass to the forming area and bend it through molds or rollers. Mold forming is suitable for complex shapes, while roller forming is suitable for simple curved surfaces. Subsequently, the glass is quickly cooled so that when the glass is subjected to external forces, the surface stress is first offset, thereby improving the bearing capacity, thereby tempering the glass. The tempered glass will enhance its resistance to wind pressure, cold and heat, impact, etc.

[0003] Considering that the existing technology usually uses hydraulics or cylinders to adjust the size and shape, although the use of hydraulics or cylinders is highly flexible and can adjust different sizes and shapes according to needs, the air tightness and the amount of hydraulic oil must be checked before each use. If the hydraulic oil or air leaks, it may not only cause errors in size and shape, but also cause the leaked hydraulic oil to contaminate the glass; and the existing technology has poor accuracy and it is difficult to accurately control the curvature of the glass; at the same time, hydraulics and cylinders will also generate a lot of noise when in use, and are usually in a high-pressure environment during use, posing a safety hazard of explosion.

[0012] Furthermore, a spring is fixedly connected to the top of the second adjusting rod, and one end of the spring away from the second adjusting rod is fixedly connected to the first adjusting rod.

[0013] Furthermore, a feeding wheel is arranged at the bottom of the feeding port, and a discharging wheel is arranged at the bottom of the discharging port.

[0014] Furthermore, a boost unit is fixedly connected to the top of the outer shell, and the boost unit includes a boost bracket, which is fixedly connected to the top of the inner wall of the outer shell.

[0016] The present invention has the following beneficial effects:

[0017] 1.

When the first adjusting rods are close to each other, the connection between the hinge block and the connecting block of the adjusting shaft can make the adjusting block bend the middle adjusting shaft downward according to gravity or the squeezing force of the second adjusting rod, thereby making it possible to press glass with a higher curvature.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9 As shown, the present invention is a curved tempered glass gradual forming device, comprising a shell 1, a material inlet 11 is provided on one side of the shell 1, a material outlet 12 is provided on the other side of the shell 1, a forming unit 2 is fixedly connected to the bottom of the shell 1, and a traction groove 13 is symmetrically provided on the inner wall of the shell 1; the traction groove 13 is L-shaped, and an adjustment unit 3 is slidably connected in the traction groove 13; the adjustment unit 3 is fixedly connected to a pressing unit 36; the forming unit 2 and the pressing unit 36 ​​cooperate to press and form the glass;

[0034] The molding unit 2 includes a molding seat 21, a cavity is opened inside the molding seat 21, a plurality of electromagnets 22 are fixedly connected to the bottom of the cavity, a shielding cover 23 is fixedly connected to the outer wall of every two electromagnets 22, and two permanent magnets 24 are slidably connected to the inner wall of the shielding cover 23, and the permanent magnets 24 are all located above the electromagnet 22.

[0035] In this embodiment, considering that the prior art usually uses hydraulic pressure or cylinders to adjust the size and shape, although the use of hydraulic pressure or cylinders is highly flexible and can adjust different sizes and shapes according to needs, the air tightness and the amount of hydraulic oil must be checked before each use. If hydraulic oil or air leaks, it may not only cause errors in size and shape, but also cause the leaked hydraulic oil to contaminate the glass; and the prior art has poor accuracy and it is difficult to accurately control the curvature of the glass; at the same time, hydraulic pressure and cylinders will also generate a lot of noise when in use, and are usually in a high-pressure environment during use, posing a safety hazard of explosion;

[0036] When the heated and softened glass enters the device, the glass enters the device through the feed port 11 and is placed above the molding unit 2. At this time, the magnetic field is generated by starting the electromagnet 22, and the permanent magnet 24 is pushed upward by the magnetic field to lift the glass. Since there are multiple electromagnets 22 in the molding seat 21, the voltage of the electromagnet 22 can be adjusted to control the magnetic force during molding, so that the permanent magnet 24 can be moved to different heights, so that the curved glass can be molded and can adapt to glass of different shapes and sizes. When it is necessary to produce glass such as gradient molding, the height of the permanent magnet 24 can be adjusted with higher precision by adjusting the voltage of the electromagnet 22 according to the shape. Since the voltage adjustment can be very precise, the curvature of the glass can also be precisely adjusted.

[0037] When the electromagnet 22 adjusts the height of the permanent magnet 24, the shielding cover 23 can prevent the permanent magnet 24 from detaching, and the shielding cover 23 can prevent the magnetic fields of the electromagnet 22 or the permanent magnet 24 from interfering with each other, thereby increasing the accuracy of the adjustment of the electromagnet 22;

[0038] After the forming is completed, the formed glass can be discharged from the equipment through the discharge port 12 and rapidly cooled, and tensile stress is formed inside the glass to enhance the strength of the glass, thereby achieving tempering of the glass;

[0039] In the prior art, there is a gradually formed curved tempered glass arc changing device with a publication number of CN104973762A. When in use, the central tooth plate connected to the fixed seat remains stationary, and the tooth plates on both sides of the central tooth plate gradually move up and rotate accordingly as the arc changing operation proceeds. The support beam is forced to move with the tooth plate by the pin shaft, and the support rollers installed thereon are arranged into the required arc shape. If a single tooth plate fails during use of the device, since the tooth plates are connected to each other, the size of the entire tooth plate may change due to a chain reaction, and the shape of the entire tooth plate pressed when pressing the glass may be uneven. When the pressed glass is tempered, it may explode due to excessive local stress.

[0040] During the use of the electromagnet 22, only a small magnetic field will be generated. Even if an equipment failure occurs, no significant loss will be caused. Since there are multiple electromagnets 22 in the forming seat 21, when some of the electromagnets 22 fail and cannot support normally, other electromagnets 22 can continue to work. During pressing, there will be other electromagnets 22 for support, so deformation caused by lack of support can be reduced, thereby avoiding uneven shapes caused by pressing.

[0041] Specifically, an adjustment block 25 is fixedly connected to each side of two permanent magnets 24 that are away from each other, and a forming shaft 26 is rotatably connected between the adjustment blocks 25 .

[0042] In this embodiment, considering that when the glass enters the device, the glass has been softened at this time, when the glass slides on the electromagnet 22, the glass may be wrinkled or deformed due to friction, which may cause uneven stress during the subsequent tempering process and lead to self-explosion;

[0043] When the glass enters the equipment from the feed port 11, the glass will move on the molding shaft 26 through the setting of the adjusting block 25 and the molding shaft 26. Since the molding shaft 26 will rotate, the friction generated by the molding shaft 26 on the glass is small, thereby reducing the deformation caused by friction and avoiding self-explosion caused by uneven stress. At the same time, since the adjusting block 25 is fixed on the permanent magnet 24, when the permanent magnet 24 is adjusted according to the size of the magnetic force, the adjusting block 25 will drive the molding shaft 26 to adjust synchronously. When the permanent magnet 24 is one high and one low, the molding shaft 26 will be tilted, which can not only make molding more convenient, but also make the contact and support area of ​​molding larger, thereby reducing the occurrence of glass deformation.

[0044] Specifically, the adjustment unit 3 includes a traction block 31 and a rack plate 33. The traction block 31 is slidably connected to the traction groove 13. Both ends of the traction block 31 are provided with traction motors. The output shaft of the traction motor is fixedly connected to a gear 32, and the gear 32 is meshed with the rack plate 33. The rack plate 33 is L-shaped and is fixedly connected to the traction groove 13.

[0045] A sliding groove 311 is provided at the bottom of the traction block 31, and a first adjusting rod 34 is slidably connected in the sliding groove 311. A second adjusting rod 35 is slidably connected to the inner wall of the first adjusting rod 34. A fixed block 37 is fixedly connected to the side close to the second adjusting rod 35, and the fixed block 37 is fixedly connected to the pressing unit 36.

[0046] In this embodiment, considering that the structure of the pressing unit 36 ​​in the prior art is usually the same as that of the molding unit 2, the size and shape of the pressing unit 36 ​​need to be adjusted to be the same as that of the molding unit 2 during the pressing process. If the molding unit 2 fails and the shape changes, the pressing unit 36 ​​will still press the glass according to its own shape because the shape does not change, which may cause the shape of the pressed glass to change. Moreover, due to the large force during the pressing process, the glass may be over-pressed, which may cause a greater change in the shape of the glass, thereby causing a greater local stress during the subsequent tempering process.

[0047] When pressing the glass, the traction motor is started to make the gear 32 drive the traction block 31 to move along the rack plate 33. Since the rack plate 33 is L-shaped, the traction block 31 will first move downward and then move toward the discharge port 12. When the traction block 31 moves downward, it will drive the first adjustment rod 34 and the second adjustment rod 35 to move downward. When the second adjustment block 25 moves downward, it will drive the fixed block 37 and the pressing unit 36 ​​to move downward. When the traction block 31 moves to the turning point of the rack plate 33, the pressing unit 36 ​​will contact the softened glass. Since the glass has been lifted and preliminarily formed by the forming unit 2 at this time, the traction block 31 is driven by the gear 32 to move toward the discharge port 12. At this time, the pressing unit 36 ​​will follow the movement and press the glass during the movement.

[0048] Since the first adjusting rod 34 will slide in the sliding groove 311, the shape of the pressing unit 36 ​​can be changed. When the shape of the glass changes, the first adjusting rod 34 will be driven to approach each other. Since the first adjusting rod 34 is passively adjusted, the shape of the pressing unit 36 ​​will be changed and adapt to the shape of the glass. Since the adjusting unit 3 will drive the pressing unit 36 ​​to passively adapt to the shape of the glass, excessive pressing due to equipment failure during glass pressing can be avoided. When the pressing equipment is pressed, it is pressed from the feed port 11 to the discharge port 12. If there is too much glass and some of the glass overflows, it will only overflow to the discharge port 12, and the excess glass at the discharge port 12 can be cut off later, thereby avoiding the overflow of the glass causing self-explosion due to uneven stress during tempering treatment, and at the same time reducing the manpower or process required to cut off both sides of the glass.

[0049] Specifically, the pressing unit 36 ​​includes multiple groups of adjusting shafts 361, and the two ends of the adjusting shafts 361 are respectively fixedly connected with hinge blocks and connecting blocks. The adjacent adjusting shafts 361 are hinged through the hinge blocks and the connecting blocks. The adjusting shafts 361 close to the fixed block 37 are fixedly connected to the fixed block 37. The outer wall of the adjusting shaft 361 is provided with a pressing shaft 362, and the pressing shaft 362 is used to press the glass.

[0050] In this embodiment, when it is necessary to press flat glass, the first adjusting rods 34 are far away from each other and on both sides of the traction block 31, and the adjusting shaft 361 will be straight at this time; when it is necessary to press curved glass, since the length of the pressing unit 36 ​​remains unchanged, when the first adjusting rods 34 are close to each other, through the connection between the hinge block and the connecting block of the adjusting shaft 361, the adjusting block 25 can bend the middle adjusting shaft 361 downward according to gravity or the extrusion force of the second adjusting rod 35, so that glass with higher curvature can be pressed; by using multiple adjusting shafts 361, not only can the curved surface of the glass be pressed wider, but the surface of the glass can also be made smoother by rolling by the pressing shaft 362, thereby increasing the stability of the glass.

[0051] Specifically, a spring 341 is fixedly connected to the top of the second adjusting rod 35 , and one end of the spring 341 away from the second adjusting rod 35 is fixedly connected to the first adjusting rod 34 .

[0052] In this embodiment, considering that thicker glass may be encountered when pressing the glass, the glass will generate a reaction force on the pressing shaft 362 during pressing, and cause it to push the second adjusting rod 35 to move upward. When the second adjusting rod 35 moves upward, since the first adjusting rod 34 cannot continue to move upward, the second adjusting rod 35 will compress the spring 341 and move upward inside the first adjusting rod 34. In this way, it can adapt to glass of different thicknesses. Compared with the prior art, glass of different thicknesses can be pressed without adjusting parameters, saving processes.

[0053] Specifically, a feeding wheel 111 is disposed at the bottom of the feeding port 11 , and a discharging wheel 121 is disposed at the bottom of the discharging port 12 .

[0054] In this embodiment, since the forming shaft 26 and the pressing shaft 362 are both passively rotated, the setting of the feeding wheel 111 and the discharging wheel 121 can add power when the glass moves, thereby allowing the glass to smoothly enter and exit the equipment.

[0055] Specifically, the top of the shell 1 is fixedly connected to the boost unit 4, and the boost unit 4 includes a boost bracket 41, and the boost bracket 41 is fixedly connected to the top of the inner wall of the shell 1. A boost motor is arranged in the middle of the boost bracket 41, and an impeller 42 is fixedly connected to the output end of the boost motor. The outer wall of the impeller 42 near the top is rotatably connected to a filter screen 43, and the filter screen 43 is fixedly connected to the shell 1.

[0056] In this embodiment, considering that the appearance or stability of the glass may be affected by the entry of impurities during pressing, when the equipment is running, the boost motor on the boost bracket 41 is started to drive the impeller 42 to rotate. At this time, the impeller 42 will suck external air into the equipment and blow out the impurities inside the equipment from the inlet 11 and the outlet 12. Since the entry of external air will cause the air pressure in the equipment to increase, external impurities cannot enter the equipment, and impurities on the surface of the glass can also be blown away when the glass enters the equipment; the setting of the filter 43 can avoid the inhalation of external impurities to ensure the quality of glass production.

[0057] Specifically, the forming shaft 26, the pressing shaft 362, the feeding wheel 111 and the discharging wheel 121 are all made of high temperature resistant materials; and the forming seat 21 is made of heat insulating materials.

[0058] In this embodiment, since the temperature of the softened glass is usually around 700 degrees Celsius, the molding shaft 26, pressing shaft 362, feed wheel 111 and discharge wheel 121 that are in contact with the glass need to use high-temperature resistant materials to avoid melting. At the same time, since the temperature of the glass is relatively high, the temperature inside the equipment may increase. By using heat-insulating materials on the molding seat 21, dimensional errors caused by temperature or damage to the equipment due to excessive temperature can be prevented during use.

[0059] When using,

[0060] First, before the glass enters, the booster motor on the booster bracket 41 is started to drive the impeller 42 to rotate. At this time, the impeller 42 will suck the external air into the equipment and blow the impurities inside the equipment out from the inlet 11 and the outlet 12. Since the entry of external air will increase the air pressure inside the equipment, external impurities cannot enter the equipment, and impurities on the surface of the glass can also be blown away when the glass enters the equipment; the setting of the filter 43 can avoid the inhalation of external impurities, so as to ensure the quality of glass production;

[0061] When the heated and softened glass enters the device, the glass enters the device through the feed port 11, and the feed wheel 111 adds power when the glass moves, so that the glass can enter the device smoothly;

[0062] When the glass moves to the top of the molding unit 2, the magnetic field is generated by starting the electromagnet 22, and the permanent magnet 24 is pushed upward by the magnetic field to lift the glass. Since there are multiple electromagnets 22 in the molding seat 21, the voltage of the electromagnet 22 can be adjusted to control the magnetic force during molding, so that the permanent magnet 24 can be moved to different heights, so that the curved glass can be molded and can adapt to glass of different shapes and sizes. When it is necessary to produce glass such as gradient molding, the height of the electromagnet 22 can be adjusted according to the shape.

[0063] When the glass enters the equipment from the feed port 11, the glass will move on the molding shaft 26 through the setting of the adjusting block 25 and the molding shaft 26. Since the molding shaft 26 will rotate, the friction generated by the molding shaft 26 on the glass is small, thereby reducing the deformation caused by friction and avoiding self-explosion caused by uneven stress. At the same time, since the adjusting block 25 is fixed on the permanent magnet 24, when the permanent magnet 24 is adjusted according to the size of the magnetic force, the adjusting block 25 will drive the molding shaft 26 to adjust synchronously. When the permanent magnet 24 is one high and one low, the molding shaft 26 will be tilted, which can not only make molding more convenient, but also make the contact and support area of ​​molding larger, thereby reducing the occurrence of glass deformation.

[0064] Secondly, when the glass is pressed, the traction motor is started to make the gear 32 drive the traction block 31 to move along the rack plate 33. Since the rack plate 33 is L-shaped, the traction block 31 will first move downward and then move toward the discharge port 12. When the traction block 31 moves downward, it will drive the first adjustment rod 34 and the second adjustment rod 35 to move downward. When the second adjustment block 25 moves downward, it will drive the fixed block 37 and the pressing unit 36 ​​to move downward. When the traction block 31 moves to the turning point of the rack plate 33, the pressing unit 36 ​​will contact the softened glass. Since the glass has been lifted and preliminarily formed by the forming unit 2 at this time, the traction block 31 is driven by the gear 32 to move toward the discharge port 12. At this time, the pressing unit 36 ​​will follow and press the glass during the movement.

[0065] Since the first adjusting rod 34 slides in the sliding groove 311, the shape of the pressing unit 36 ​​can be changed. When the shape of the glass changes, the first adjusting rod 34 is driven to move closer to each other. Since the first adjusting rod 34 is passively adjusted, the shape of the pressing unit 36 ​​is changed and adapted to the shape of the glass. Since the adjusting unit 3 drives the pressing unit 36 ​​to passively adapt to the shape of the glass, excessive pressing due to equipment failure during glass pressing can be avoided. When the pressing device is pressed, the pressing is performed from the feed port 11 to the discharge port 12. If there is too much glass and some of the glass overflows, it will only overflow to the discharge port 12, and the excess glass at the discharge port 12 can be cut off later, thereby avoiding the self-explosion caused by uneven stress during tempering due to glass overflow, and at the same time, less manpower or processes are required to cut off both sides of the glass.

[0066] When it is necessary to press flat glass, the first adjusting rods 34 are far away from each other and on both sides of the traction block 31, and the adjusting shaft 361 will be straight at this time; when it is necessary to press curved glass, since the length of the pressing unit 36 ​​remains unchanged, when the first adjusting rods 34 are close to each other, through the connection between the hinge block and the connecting block of the adjusting shaft 361, the adjusting block 25 can be made to bend the middle adjusting shaft 361 downward according to gravity or the squeezing force of the second adjusting rod 35, so that glass with a higher curvature can be pressed; by using multiple adjusting shafts 361, not only can a wider curved surface of the glass be pressed, but the surface of the glass can also be made smoother by rolling the pressing shaft 362, thereby increasing the stability of the glass;

[0067] When pressing, the glass will generate a reaction force on the pressing shaft 362, and push the second adjusting rod 35 to move upward. When the second adjusting rod 35 moves upward, since the first adjusting rod 34 cannot continue to move upward, the second adjusting rod 35 will compress the spring 341 and move upward inside the first adjusting rod 34. This can adapt to glass of different thicknesses. Compared with the existing technology, glass of different thicknesses can be pressed without adjusting parameters, saving processes.

[0068] Finally, when the forming is completed, the formed glass is powered by the discharge wheel 121, so that the glass is discharged from the equipment through the discharge port 12, and then quickly cooled to form tensile stress inside the glass to enhance the strength of the glass, thereby achieving tempering of the glass.
