[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0041] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0042] Embodiment 1:
[0043] This embodiment mainly describes the basic structure and principle of 3D glass hot bending forming equipment, specifically:
[0044] like Figure 1-Figure 2 As shown, the present application provides a glass 3D hot bending automatic forming device, including a forming mechanism 1, which is used to hot bend the cut glass, so that the glass is transformed from a flat state to a 3D curved state;
[0045] The forming mechanism 1 includes a support frame 11, which is generally placed on the floor of a workshop and mainly provides stable support for the forming mechanism 1 to ensure the normal operation of the forming mechanism 1;
[0046] like Figure 3 and Figure 8 As shown, a bottom plate 12 is fixedly mounted on the upper end of the support frame 11, and a mold core 110 is fixedly mounted on the upper end of the bottom plate 12. A through receiving groove 123 is provided on the mold core 110, and the receiving groove 123 is used to place glass;
[0047] At the same time, a receiving platform 111 is slidably arranged inside the receiving groove 123, and the top of the receiving platform 111 is used to carry the glass, and an elastic body 122 is installed between the bottom of the receiving platform 111 and the bottom plate 12, so that when the glass placed on the receiving platform 111 is pressurized, the receiving platform 111 will drop accordingly, and after the above pressure disappears, the receiving platform 111 is slowly reset by the elastic body 122. It should be noted that a convex mold is arranged at the upper end of the receiving platform 111, and the convex mold is adapted to the lower surface of the formed 3D glass, so it can be understood that in the initial state, the glass in the flat state can only overlap the upper end of the convex mold until the glass is hot-bent and formed, and can be completely fitted in the convex mold, and in the process of changing the state of the glass, the middle part of the glass is convex, and the surrounding parts of the glass are concave, so that the receiving platform 111 needs to move upward to be completely fitted with the 3D curved glass, and the rising process of the receiving platform 111 can be driven by the elastic body 122, and the specific principle is described in detail below;
[0048] like Figure 1-Figure 2 As shown, at least three groups of guide pillars 14 are fixedly mounted on the bottom plate 12, a top plate 16 is fixedly mounted on the top of the guide pillars 14, and a first cylinder 17 is fixedly mounted on the top plate 16, and the first cylinder 17 is a main driving cylinder of the molding mechanism 1;
[0049] At the same time, the output end of the first cylinder 17 is vertically arranged, and a slide plate 18 is fixedly installed on the output end of the first cylinder 17, so that the slide plate 18 can move in the vertical direction under the push of the first cylinder 17;
[0050] It should be noted that a guide sleeve 19 adapted to the guide post 14 is fixedly provided on the slide plate 18, so that during the movement of the slide plate 18, the slide plate 18 is guided by the cooperation between the guide sleeve 19 and the guide post 14;
[0051] like Figure 4 and Fig.10 As shown, a connecting plate 115 is fixedly arranged at the bottom of the slide plate 18, a spring 114 is fixedly installed at the bottom of the connecting plate 115, and a pressing sleeve 112 is fixedly installed at one end of the spring 114 away from the connecting plate 115, and the pressing sleeve 112 has a molding groove 113 adapted to the molded 3D curved glass;
[0052] It should be noted that the molding groove 113 is a concave cavity, which is adapted to the upper surface of the 3D glass after molding. In the initial state, the flat glass can only overlap the lower end of the concave cavity until the glass is hot-bent and molded, and can be completely attached to the concave cavity. During the change of the glass state, the glass moves upward and is completely attached to the 3D curved glass, and the upward movement of the glass is synchronized with the movement of the accommodating table 111.
[0053] At the same time, in order to maintain the sealing of the glass during hot bending, a sealing arrangement is adopted between the pressing sleeve 112 and the mold core 110 to form a molding cavity. Specifically, an annular groove (not shown in the figure) is arranged on the outer ring of the accommodating groove 123 on the upper surface of the mold core 110, and a flange (not shown in the figure) adapted to the annular groove is arranged at the lower end of the pressing sleeve 112, so that when the pressing sleeve 112 and the mold core 110 are close to each other, the flange will be inserted into the annular groove to form the above-mentioned molding cavity;
[0054] Furthermore, a high temperature resistant sealing ring (not shown in the figure) is arranged on the outer side of the flange, so that as long as the flange is inserted into the annular groove, the molding cavity is in a sealed state, and when the flange moves in the annular groove, the molding cavity is always in a sealed state;
[0055] Furthermore, the molding cavity is provided with an air inlet and an air outlet, the air inlet is used to introduce an inert gas into the molding cavity, and the air outlet is used to discharge the inert gas in the molding cavity. The inert gas is argon, nitrogen, etc., which is used to discharge the oxygen in the molding cavity to prevent the oxygen from affecting the quality of the glass product. In the present application, the air inlet and can be provided on the pressing sleeve 112 at the same time, or can be provided on the pressing sleeve 112 and the mold core 110 respectively, as long as the air inlet and the air outlet are both connected to the molding cavity, thereby facilitating the input and output of the inert gas.
[0056] like Figure 3 and Figure 8 As shown, a heating mechanism 2 is arranged outside the pressing sleeve 112 and the mold core 110. The heating mechanism 2 adopts a high-frequency heating method to heat the glass in the molding cavity. The heating mechanism 2 includes a side frame 21 fixedly mounted on the support frame 11, and a fourth cylinder 22 is fixedly mounted on the side frame 21. The output end of the fourth cylinder 22 is arranged in the vertical direction, and a vertical plate 23 is fixedly mounted. An induction coil 24 is fixedly mounted on the vertical plate 23. The induction coil 24 is sleeved on the outside of the pressing sleeve 112 and the mold core 110, so that the induction coil 24 can move in the vertical direction under the drive of the fourth cylinder 22, so that the induction coil 24 can be adjusted to be in a suitable position to heat the glass.
[0057] It can be understood that the induction coil 24 is a high-frequency heating device, and heats the glass in the molding cavity in a non-contact manner.
[0058] like Figure 1 As shown, a distribution box 13 is fixedly mounted on the support frame 11, and a PLC control system is provided in the distribution box 13. The PLC control system is used to coordinate the collaborative work between various electrical components so that the glass 3D hot bending automatic forming equipment can operate stably according to the established program.
[0059] In summary, when the glass needs to be hot-bent, the glass in a flat state is first placed on the upper end of the receiving platform 111, and then the first cylinder 17 is driven to drive the pressing sleeve 112 to approach the receiving platform 111 until the molding groove 113 is pressed on the upper end of the glass. At this time, the flange on the pressing sleeve 112 is inserted into the annular groove of the mold core 110, so that a sealed molding cavity is formed;
[0060] Then the induction coil 24 is driven by the fourth cylinder 22 to be located outside the molding cavity and start heating the glass. During the heating process, inert gas is filled into the molding cavity to discharge oxygen in the molding cavity to prevent oxygen from affecting the quality of the glass product.
[0061] During the glass forming process, as the glass softens at high temperature, the upper surface of the glass slowly fits with the concave cavity, and the lower surface of the glass slowly fits with the convex mold. Because the elastic body 122 is compressed at this time, it always exerts an upward thrust on the receiving platform 111, and slowly pushes the receiving platform 111 to move upward to adapt to the above-mentioned bonding process. Finally, the glass is in a completely bonded state, thereby achieving the purpose of continuous molding.
[0062] After the glass is formed, the first cylinder 17 drives the pressing sleeve 112 to move upward, thereby making it easier for the staff to take out the formed 3D glass.
[0063] At the same time, in order to facilitate the removal of 3D glass, Fig.10 As shown, a demolding assembly is arranged on the pressing sleeve 112, and the demolding assembly includes a fifth cylinder 116 fixedly mounted on the upper end of the pressing sleeve 112, and a top block 117 is fixedly mounted on the output end of the fifth cylinder 116, and a through hole (not marked in the figure) is arranged on the pressing sleeve 112, and the through hole is used for the passage of the top block 117, so that the fifth cylinder 116 can drive the top block 117 to protrude through the through hole and enter the interior of the molding groove 113, and eject the 3D glass to prevent the 3D glass from adhering to the interior of the molding groove 113. It should be noted that, in the initial state, the top block 117 is adapted to the through hole so that the molding groove 113 forms a whole to avoid affecting the molding of the glass.
[0064] In this embodiment, due to the arrangement of the convex mold at the upper end of the receiving platform 111, it is difficult to keep the glass stable when placed. In order to solve this problem, Figure 4 and Fig. 9 As shown, a clamping mechanism 3 is provided on the slide plate 18, and the clamping mechanism 3 includes a second cylinder 31 fixedly mounted on the slide plate 18, and a push plate 32 is fixedly mounted on the output end of the second cylinder 31, so that the push plate 32 can move in the vertical direction under the drive of the second cylinder 31;
[0065] Meanwhile, a third cylinder 33 is fixedly mounted on the push plate 32, and a clamping block 34 is fixedly mounted on the output end of the third cylinder 33, so that the clamping block 34 can move in the horizontal direction under the drive of the third cylinder 33;
[0066] The clamping mechanism 3 is provided with two groups, so that the two groups of clamping blocks 34 can be close to each other to clamp and stabilize the glass placed on the upper end of the receiving platform 111, so that the glass can be located at the center position of the receiving platform 111, and after the glass is stabilized, the two groups of clamping blocks 34 move away from each other and reset to prevent affecting the downward movement of the pressing sleeve 112.
[0067] It should also be noted that the glass 3D hot bending automatic forming equipment of the present application also includes at least one cold circulation system, which is used for cooling the 3D glass after forming. The cold circulation system includes a water storage device and a cooling device. At the same time, a water inlet and a water outlet are provided on the water storage device, and a cooling pipeline can be provided on the outer ring of the pressing sleeve 112 and the mold core 110, wherein the water inlet and the water outlet are respectively connected to the cooling device, and the cooling pipelines of the pressing sleeve 112 and the mold core 110, so as to realize water cooling circulation, and then cool the pressing sleeve 112 and the mold core 110;
[0068] At the same time, the water storage device is used to store cooling water, and the cooling equipment is used to cool the cooling water. The cooled cooling water flows from the water outlet into the cooling pipeline of the press sleeve 112 and the mold core 110. After cooling the press sleeve 112 and the mold core 110, it flows back to the water storage device from the water inlet, thereby realizing the cold cycle.
[0069] Embodiment 2:
[0070] In the final stage of the glass forming, the separation of the pressing sleeve 112 from the mold core 110 may cause the formed curved glass to rebound, thereby failing to achieve the preset curvature and size.
[0071] In order to solve the above problems, Figure 1 and Figure 5 As shown, an arc block 121 is fixedly mounted on the pressing sleeve 112, and a slide table 5 is fixedly mounted on the arc block 121;
[0072] At the same time, an auxiliary platform 15 is fixedly installed on the bottom plate 12, and a guide rod 4 is arranged on the auxiliary platform 15. The guide rod 4 is suitable for cooperating with the slide 5 to limit the position of the press sleeve 112;
[0073] like Figure 6-Figure 7 As shown, the guide rod 4 includes a seat body 41 fixedly mounted on the auxiliary platform 15, a rod body 42 is rotatably mounted on the seat body 41, and a ball 43 is fixedly mounted on one end of the rod body 42 away from the seat body 41, and the ball 43 has a certain elasticity;
[0074] Meanwhile, a slideway matching the ball 43 is arranged on the slide platform 5, and the slideway includes a vertically arranged first slideway 51, and in the initial state, the ball 43 is located in the first slideway 51;
[0075] Continue to refer Figure 7 The first slideway 51 is connected to a second slideway 52 which is arranged obliquely upward, and the groove bottom position of the second slideway 52 is lower than the groove bottom position of the first slideway 51, so that the ball 43 is suitable for entering the second slideway 52 from the first slideway 51, but cannot return to the first slideway 51 from the second slideway 52;
[0076] At the same time, a third slideway 53 is connected to the end of the second slideway 52 and is inclined downward. The bottom position of the third slideway 53 is lower than the bottom position of the second slideway 52, so that the ball 43 is suitable for entering the third slideway 53 from the second slideway 52, but cannot return to the second slideway 52 from the third slideway 53, and a first stationary point 56 is provided at the intersection of the second slideway 52 and the third slideway 53, and the first stationary point 56 is located in the third slideway 53;
[0077] The third slideway 53 is connected to a fourth slideway 54 which is inclined upward at the end thereof. The groove bottom position of the fourth slideway 54 is lower than the groove bottom position of the third slideway 53, so that the ball 43 is suitable for entering the fourth slideway 54 from the third slideway 53, but cannot return to the third slideway 53 from the fourth slideway 54. Meanwhile, a second stationary point 57 is provided at the connection between the third slideway 53 and the fourth slideway 54, and the second stationary point 57 is located in the fourth slideway 54.
[0078] In this embodiment, the first cylinder 17 does not need to be extended all the time to resist the pressing sleeve 112. The first cylinder 17 only needs to be extended and then retracted. The position of the pressing sleeve 112 can be fixed by the cooperation of the ball 43 and the slideway. Specifically:
[0079] When the first cylinder 17 is extended, the ball 43 enters the second slideway 52 along the first slideway 51 until the ball 43 reaches the first stationary point 56. At this time, the additional extension of the first cylinder 17 is absorbed by the spring 114.
[0080] When the first cylinder 17 retracts and resets, the ball 43 moves from the first stationary point 56 along the third slideway 53 to the second stationary point 57. At this time, the ball 43 is restricted by the second stationary point 57, so that the position of the pressing sleeve 112 is fixed;
[0081] Then, the glass is bent by heat. The specific process of the bending process has been described in the first embodiment and will not be repeated here.
[0082] Continue to refer Figure 7, a fifth slide 55 extending vertically downward is connected at the end of the fourth slide 54, and the fifth slide 55 is composed of a first section close to the fourth slide 54 and a second section close to the first slide 51, wherein the groove bottom position of the first section is lower than the groove bottom position of the fourth slide 54, so that the ball 43 is suitable for entering the first section from the fourth slide 54, but cannot return to the fourth slide 54 from the first section, and a third stationary point 58 is provided at the connection between the fourth slide 54 and the first section, and the third stationary point 58 is located in the first section, and the position of the third stationary point 58 is higher than the position of the first stationary point 56;
[0083] At the same time, the bottom position of the second section gradually rises in the direction close to the first slideway 51, and a step is formed at the connection with the first slideway 51, so that due to the existence of the step, the ball 43 is suitable for entering the first slideway 51 from the second section, but cannot enter the second section from the first slideway 51;
[0084] Therefore, when the first cylinder 17 is extended again, the ball 43 will reach the position of the third stationary point 58 from the second stationary point 57 via the fourth slide 54. Because the position of the third stationary point 58 is higher than the position of the first stationary point 56, the pressing sleeve 112 will drop a greater distance at this time, so as to perform a second pressing with greater strength on the formed 3D glass, so that the 3D glass is better fitted with the forming groove 113 and the receiving platform 111, and the rebound of the 3D glass after forming is also avoided;
[0085] Then the first cylinder 17 retracts and resets, and the ball 43 also returns to the initial position of the first slide 51 along the fifth slide 55 to prepare for the next glass molding.
[0086] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
