Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle glass processing equipment, and particularly relates to a vehicle glass hot bending machine. BACKGROUND

[0002] Vehicle glass adopts flat glass, after cutting, is moved to a mold, is softened after high-temperature heating, is bent and formed under self-gravity and external pressure, and is cooled to be made into curved glass. Then, the curved glass is polished and processed through horizontal transportation, so that the production of vehicle glass is completed.

[0003] Patent publication No. CN112520988B discloses a vehicle glass hot bending machine and a control method thereof. The hot bending machine comprises an upper die, a lower die, a main bottom plate, a vehicle glass hot bending mold reciprocating pushing mechanism, a vehicle glass hot bending heating device and a vehicle glass hot bending lifting pre-pressing forming mechanism. The vehicle glass hot bending mold reciprocating pushing mechanism is arranged on the main bottom plate, and a linear bearing is arranged on the front wall of the heating cavity. The vehicle glass hot bending mold reciprocating pushing mechanism comprises a linear ball screw transmission module, a rotary cylinder, a rotary cylinder seat and a rotary rod. The vehicle glass hot bending heating device is arranged in a heating area, and comprises a fixed plate. Lamp pipe frames are arranged on the left and right sides below the fixed plate, and a plurality of halogen lamp pipes are arranged between the lamp pipe frames. The vehicle glass hot bending lifting pre-pressing forming mechanism is arranged at the top of a forming area. The application can complete the processing of complex products, improve production efficiency and product quality, reduce the size of the equipment, and save the placement space of the equipment.

[0004] In the prior art, the forming area and the heating area are arranged to process complex curved glass, but there are still some problems. Firstly, the existing vehicle glass hot bending machine heats the glass first, and then horizontally transports the glass to the bending area for extrusion and shaping. Therefore, the glass needs to be heated multiple times, and the glass is prone to deformation during transportation, which affects the processing efficiency and easily causes processing defects of the glass. Secondly, after the vehicle glass is extruded and formed, it needs to be cooled. The existing processing equipment usually cools and cools during transportation. Since the glass is curved and has a high temperature, if shaking occurs during transportation, the curvature of the glass after cooling will change, thereby affecting the processing quality of the vehicle glass. Finally, during the processing of the existing vehicle glass, the glass needs to be horizontally transported. However, the existing clamping and conveying assembly cannot smoothly complete the clamping conversion when the glass is in a planar state and an arcuate state after hot bending, thereby affecting the horizontal conveying efficiency of the glass.

DETAILED DESCRIPTION

[0019] In order to make the person in the art better understand the present application scheme, the technical scheme in the embodiment of the present application will be described clearly and completely below by combining the drawings in the embodiment of the present application.

[0020] Example one: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a vehicle-mounted glass hot bending machine comprises a workbench 10, a concave die 12 fixedly arranged on the upper end surface of the workbench 10, and the upper end surface of the concave die 12 is arranged in a concave arc structure, which is adaptively processed and produced according to the bending arc of the produced glass. Meanwhile, the upper end arc surface of the concave die 12 is sprayed with a high-temperature-resistant anti-sticking coating with a thickness of 15-25 μm, so that the concave die 12 improves the smoothness of the contact surface between the glass and the concave die 12 when cooperating with other components to heat-bend and form the glass. The upper side of the concave die 12 is fixedly arranged with a first support frame 11 on the upper end surface of the workbench 10, the first support frame 11 is formed by a plurality of rod members and plate members through bolt fastening, and a convex die 13 matched with the concave die 12 is slidably arranged in the first support frame 11. The lower end of the convex die 13 is arranged in an outer convex arc structure, and the arc of the arc surface is the same as the arc of the upper end arc surface of the concave die 12. The upper side of the convex die 13 is fixedly arranged with a second push cylinder on the upper end surface of the first support frame 11, and the output end of the second push cylinder is fixedly connected with the upper end surface of the convex die 13 through the first support frame 11. The second push cylinder is selected to be a hydraulic push cylinder with self-locking function and large thrust, and the output end of the second push cylinder drives the convex die 13 to move downward, and cooperates with the concave die 12 to form the extrusion and shaping of the glass after the inner arc surface of the concave die 12 is heated.

[0021] Further, as shown in Figure 5 One side of the concave die 12 is arranged with a placing table 32 on the upper end surface of the workbench 10, and the upper end surface of the placing table 32 places the cleaned glass original piece. The other side of the concave die 12 is fixedly arranged with a third support frame 33 on the upper end surface of the workbench 10, and a plurality of transmission rollers 48 are rotatably arranged in the third support frame 33 through bearing seats. The plurality of transmission rollers 48 can be driven by a motor or mechanically synchronously driven to form a conveying line, which can horizontally convey the hot-bending formed glass product to the next process. The surface of the transmission roller 48 is coated with a high-temperature-resistant silica gel layer with a thickness of 3-5 mm, which ensures the scratch prevention and thermal stability during the glass conveying process.

[0022] Further, as shown in Figure 5 and Figure 6As shown, the punch 13 has a second cavity 47 inside. The inner bottom surface of the second cavity 47 has the same curvature as the lower end arc surface of the punch 13. The inner bottom surface of the second cavity 47 is evenly provided with a plurality of first elongated holes 14. A first sealing strip 15 is slidably disposed inside each first elongated hole 14. The surfaces of the plurality of first sealing strips 15 are polished to match the curvature of the punch arc surface. This ensures that when the punch 13 is engaged inside the first elongated hole 14, the complete curvature of the lower end arc surface is maintained so that no gaps appear. The first sealing strip 15 is made of high temperature resistant alloy material to ensure that the deformation is controllable when in contact with high temperature glass. Multiple first sealing strips 15 are fixedly connected by first fixed connecting brackets 16 at both ends to ensure that the sliding of multiple first sealing strips 15 is synchronized. At the same time, a rotating rod 21 is rotatably provided above the multiple first sealing strips 15 inside the second cavity 47. An elastic telescopic component is connected between the rotating rod 21 and both ends of each first fixed connecting bracket 16. An inclined sliding surface 17 is provided on the same side wall of each first elongated hole 14. One side wall of each first sealing strip 15 is slidably connected to the first elongated hole 14. The inclined sliding surface 17 mainly serves as a guide to facilitate the sliding of the first sealing strip 15 from the inside of the first elongated hole 14 to the inside of the second cavity 47, thereby opening and closing the first elongated hole 14.

[0023] A fourth motor is fixedly installed on one side of the rotating rod 21 on the outer wall of the punch 13. The output end of the fourth motor passes through the punch 13 and is fixedly connected to the axis of the rotating rod 21. The fourth motor is a high-torque servo motor with a self-locking function at its output end. The fourth motor drives the rotating rod 21 to rotate. Through the rotational connection of multiple elastic telescopic components, an arc rotation is formed on the first fixed connecting frame 16 and multiple first sealing strips 15. Under the inclined guidance of the inclined sliding surface 17, the multiple first sealing strips 15 drive the first fixed connecting frame 16 to compress the length of the elastic telescopic components and slide into the interior of the second cavity 47, opening multiple first long holes 14. This facilitates the subsequent heating of the glass placed on the inner arc surface of the lower concave mold 12 through the multiple first long holes 14, causing the glass to deform due to heat.

[0024] It should be noted here that, with Figure 5 For example, the rotation direction of the rotating rod 21 is counterclockwise. When the rotating rod 21 rotates counterclockwise, each elastic telescopic component is subjected to torque and undergoes synchronous radial contraction, driving the first fixed connecting frame 16 to drive all the first sealing strips 15 to slide out axially along the first long hole 14 and be guided into the inner cavity of the second cavity 47 along the inclined sliding surface 17.

[0025] Furthermore, such as Figure 5 and Figure 6As shown, one side of each first sealing long strip 15 is fixedly connected with a second support frame 22 between two first fixed connection frames 16, and the lower end surface of each second support frame 22 is fixedly provided with a plurality of infrared heating units 23, which include silicon carbide heating tubes capable of emitting infrared electromagnetic waves and corresponding heating control circuits and controllers. This is prior art, and will not be described in detail in this application. When the first sealing long strip 15 rotates away from the inside of the first long hole 14, the plurality of infrared heating units 23 rotate to a position above the axis of the first long hole 14 with the second support frame 22. Each infrared heating unit 23 is electrically connected to an external power supply and a controller, forming start-stop control of the infrared heating unit 23. The infrared heating unit 23 emits infrared electromagnetic waves, which are absorbed by glass molecules. The glass converts the absorbed infrared electromagnetic waves into molecular thermal motion internal energy, causing the glass to rapidly and uniformly heat and soften. At this time, after adjusting the horizontal position of the convex mold 13, the infrared electromagnetic waves emitted by the output end of the plurality of infrared heating units 23 are started to form a heating treatment of the glass. After being heated, the glass is deformed by bending to the inner arc surface of the concave mold 12 under the action of its own gravity, thereby preliminarily heat bending the glass.

[0026] It should be noted that, since the plurality of first long holes 14 and the plurality of infrared heating units 23 are arranged in a ring array and concentrically arranged with the inner arc surface of the concave mold 12, the density of the infrared electromagnetic waves emitted by each infrared heating unit 23 decreases along the radial direction of the glass, thereby forming a temperature field on the upper surface of the glass that gradually weakens from the center to the edge. This effectively avoids the problem of edge overheating and warping and center non-softening caused by traditional uniform heating, ensuring that the stress release rate of each region of the glass matches its thermal expansion gradient during bending, causing the glass to gradually bend and deform from the center to both sides, effectively improving the heat bending forming quality of the glass.

[0027] Further, as shown in Figure 5 and Figure 9 , the elastic expansion assembly includes a second sliding rod 19 rotationally connected with the first fixed connection frame 16 and a first sliding rod 18 rotationally connected with the rotating rod 21. Each two adjacent first sliding rods 18 and second sliding rods 19 are slidingly connected, and a spring 20 is arranged inside the first sliding rod 18 between the first sliding rod 18 and the second sliding rod 19. The spring 20 is a compression spring made of high-temperature-resistant material, and is away from the plurality of infrared heating units 23, so that the influence of the output heat of the infrared heating units 23 is limited, and the elastic tensioning effect can be ignored.

[0028] Further, as shown in Figure 5As shown, a heat insulation plate 46 is fixedly installed above the multiple infrared heating units 23 inside the second cavity 47. The heat insulation plate 46 is made of high thermal conductivity ceramic fiber composite material and is used to block the heat generated by the infrared heating units 23 from being conducted to the upper part of the inner cavity of the second cavity 47, thereby further forming high temperature protection for the spring 20.

[0029] Furthermore, such as Figure 5 and Figure 7 As shown, the interior of the die 12 is provided with a first cavity 24, and the upper inner arc surface of the die 12 is evenly provided with a plurality of second elongated holes 25 that communicate with the first cavity 24. A second sealing strip 26 is slidably disposed inside each second elongated hole 25. The second sealing strip is made of the same material as the first sealing strip, and its outer end face is flush with the inner arc surface of the die 12. A second fixed connecting frame 27 is slidably disposed below the plurality of second sealing strips 26 inside the first cavity 24. The second fixed connecting frame 27 is fixedly connected to both ends of the plurality of second sealing strips 26 above it.

[0030] Each second elongated hole 25 has a ventilation hole 29 on its inner sidewall. A cold air output component is externally connected to multiple ventilation holes 29 on one sidewall of the die 12. This component can output cold air at different temperatures and blow it into the interior of the second elongated hole 25 through multiple ventilation holes 29, thereby cooling the glass above the multiple second elongated holes 25 after hot bending.

[0031] Meanwhile, a third pusher cylinder is fixedly installed on the lower end face of the first cavity 24. The third pusher cylinder adopts a hydraulically driven linear pusher rod, and its piston rod end passes through the concave mold 12 and is fixedly connected to the lower end face of the second fixed connecting frame 27. The extension and retraction of the third pusher cylinder drives the second fixed connecting frame 27 to slide along the axial direction of the first cavity 24. When the glass needs to be hot-bent, the second fixed connecting frame 27 drives multiple second sealing strips 26 to slide and engage inside the second elongated hole 25 to ensure the flat structure of the inner arc surface of the concave mold 12 and form a stable support for the lower end face of the glass. After the glass is formed, the output end of the third pusher cylinder drives the second fixed connecting frame 27 and multiple second sealing strips 26 to move down, so that the multiple second sealing strips 26 are released from the seal of the ventilation holes 29 at both ends, and the multiple second elongated holes 25 form a uniform strip-shaped ventilation groove on the lower end face of the hot-bent glass. The cold air output component continuously outputs cold air into the interior of the second sealing strips 26 through multiple ventilation holes 29 to form a relatively proportional uniform cooling treatment.

[0032] It should be noted that the hot air output by the aforementioned cold air output component should gradually decrease with the cooling time to prevent micro-cracks or stress concentration on the glass surface due to sudden cooling.

[0033] Furthermore, such as Figure 5 andFigure 7 As shown, the cold air output assembly includes a cold air storage frame 28 arranged on one side wall of the concave mold 12. One side wall of the cold air storage frame 28 is provided with a plurality of cold air machines 30 in communication with the internal cavity of the cold air storage frame 28. The cold air machine 30 is a variable frequency speed regulating centrifugal cold air machine, a PID temperature control module and an annular air duct. The air outlet of the cold air machine is in one-to-one correspondence with the air vent 29 of the side wall of the concave mold through a flexible air guide pipe. The temperature control module collects the infrared temperature of the glass surface in real time and dynamically adjusts the cold air temperature to be between 25°C and 120°C, so as to ensure that the hot bent glass completes gradient controlled cooling before being separated from the concave mold and suppresses the rebound deformation. The output cold air can be dynamically adjusted in temperature and air pressure according to the cooling demand of different time periods, so as to ensure stable and continuous cooling treatment of the glass.

[0034] Further, as shown in Figure 7 , the internal cavity of the cold air storage frame 28 is provided with a filter plate 31. The filter plate 31 is a multi-layer metal sintered mesh structure, which is used to intercept dust and other impurities carried in the cold air, so as to increase the light transmittance of the glass while cooling the surface of the glass.

[0035] Example two: On the basis of example one, further examples are made, as shown in Figure 4 , Figure 5 and Figure 8As shown, the two sides of the concave die 12 are fixedly provided with first sliding frames 34 on the upper end face of the workbench 10, the inside of each first sliding frame 34 is vertically slidably provided with a second sliding frame 35, the inside of each second sliding frame 35 is horizontally slidably provided with a first sliding block 36 and a second sliding block 43, one side of each first sliding block 36 and second sliding block 43 is slidably provided with a first motor 38, the output end of each first motor 38 is provided with an electric sliding ring, and an electric clamp jaw 39 is provided outside the electric sliding ring, so that when the electric clamp jaw 39 clamps the object, the first motor 38 can drive the electric clamp jaw 39 to rotate. The side wall of each first sliding block 36 and second sliding block 43 is fixedly provided with a first push cylinder 37, the output end of each first push cylinder 37 penetrates through the first sliding block 36 or the second sliding block 43 and is fixedly connected with the side wall of the first motor 38, the upper end face of the first sliding frame 34 is fixedly provided with a fourth push cylinder, the output end of the fourth push cylinder penetrates through the first sliding frame 34 and is fixedly connected with the upper end face of the second sliding frame 35, the second sliding frame 35 is driven to vertically slide in the inside of the first sliding frame 34 by the fourth push cylinder, thereby adjusting the horizontal clamping position of the plurality of electric clamp jaws 39. At the same time, the output end of the first push cylinder 37 drives the first motor 38 and the electric clamp jaw 39 to horizontally approach and clamp the glass to be clamped, and the rotation angle of the electric clamp jaw 39 is adjusted by the first motor 38, so that when the glass is clamped after hot bending forming, the stable clamping of the glass is more suitable by adjusting the clamping angle and the distance between the two electric clamp jaws 39.

[0036] The inside of the second sliding frame 35 is rotatably provided with a first lead screw 44, the first lead screw 44 is threadedly connected with the second sliding block 43, the first lead screw 44 is slidably connected with the first sliding block 36, one end of the first lead screw 44 is fixedly provided with a second motor on the outside of the first sliding frame 34, the output end of the second motor drives the first lead screw 44 to rotate, thereby forming the horizontal sliding displacement of the second sliding block 43 in the inside of the second sliding frame 35, the side wall of the second sliding block 43 is fixedly provided with a third motor, the output end of the third motor is rotatably provided with a second lead screw 45, the second lead screw 45 is threadedly connected with the adjacent second sliding block 43, each second lead screw 45 is rotatably connected with the adjacent first sliding block 36, and the side wall of each first sliding block 36 is provided with a third motor driving the second lead screw 45 to rotate, the output end of the third motor drives the second lead screw 45 to rotate, thereby driving the first sliding block 36 to axially synchronously slide along the first lead screw 44, adjusting the distance between the first sliding block 36 and the second sliding block 43, so that the clamping position of the plurality of electric clamp jaws 39 can be adaptively adjusted after the overall horizontal length of the glass changes after hot bending deformation, thereby ensuring the clamping stability of the glass.

[0037] It should be noted that the first motor, the second motor and the third motor are high-precision servo motors, and real-time communication is realized through the PLC control system, and the speed, torque and displacement parameters of each motor are dynamically calibrated through a preset algorithm, so that precise closed-loop control of the clamping angle, displacement speed and positioning accuracy can be realized, and the attitude stability of the hot-bent glass during the whole transportation and cooling process is ensured, so that adaptive clamping and transportation of the glass in different stages are formed.
