Description

Technical Field

[0001] This invention relates to the field of glass pressure forming technology, specifically to a mechanical device for uniformly pressing and forming tempered glass. Background Technology

[0002] Tempered glass is a type of safety glass made by strengthening ordinary flat glass through physical or chemical methods. Its core principle involves heating the glass to near its softening point, then uniformly and rapidly blowing high-pressure cold air onto its surface or forming a surface compressive stress layer through ion exchange. This creates compressive stress on the glass surface and tensile stress within. The uniform pressure forming process specifically refers to the application of uniform pressure to the heated and softened glass during hot bending or molding tempering. The purpose is to ensure that the glass surface fits perfectly with the mold, forming a precise curvature or surface.

[0003] In existing technologies, tempered glass is formed under uniform pressure. Ordinary flat glass is cut, edged, and cleaned, then heated in a furnace to its softening point, making it malleable. The softened glass is then rapidly conveyed to a lower mold via a high-temperature conveyor roller. A hydraulic pusher drives the upper mold downwards, applying uniform and stable pressure to the placed flat glass for extrusion, precisely shaping the glass into the target curved surface or shape between the upper and lower molds. After extrusion, an external robotic arm removes the formed glass from the lower mold and quickly transports it to an annealing furnace for slow cooling to eliminate internal thermal stress, ultimately yielding an annealed hot-pressed glass product.

[0004] However, during operation, if the hydraulic press presses down too quickly, the glass may be cracked or internal stress may be concentrated. If the hydraulic push rod moves down too fast, when the upper mold comes into contact with the high-temperature softened glass, the impact force may be too great, causing the glass to have excessively deep local dents, uneven thickness, or even direct cracking.

[0005] Although the above problems can be solved by controlling the downward pressure buffer, after soft contact, the upper mold is rebounded or suspended, resulting in incomplete mold closing. Since the buffer mechanism generates a reaction force before contacting the glass, although the hydraulic push rod slows down, it may not be able to overcome the buffer reaction force. As a result, the upper mold cannot continue to press down to the set mold closing position after contacting the glass, resulting in an excessive gap between the upper and lower molds, the glass is not pressed to the designed thickness, the product dimensions are out of tolerance, and it may even be unable to fit the complex curved surface of the mold. Summary of the Invention

The bottom inner wall of the threaded block is threadedly connected to the outer surface of the bidirectional screw. The interior of the second pulley is fixedly mounted to the outer surface of the receiving rod. The inner ring of the transmission belt is driven to the outer surface of the second pulley. The outer surface of the first pulley is driven to the inner ring of the transmission belt.

[0010] Preferably, one end of the compression spring is fixedly installed to the upper surface of the base, and one end of the telescopic rod is fixedly installed to the upper surface of the base.

[0011] Preferably, the U-shaped frame has a rectangular groove inside, and the gear is installed between the inside of the rectangular groove and the gear.

[0012] Preferably, the cam's buffer portion is initially attached to the upper surface of the bonding plate, and during overall operation, the cam's convex portion is attached to the upper surface of the bonding plate, and exerts downward pressure on the compression spring and telescopic rod.

[0013] Preferably, the inner surface of the pulley is fixedly installed on the outer surface of the rotating shaft, and the inner surface of the threaded block is provided with a insertion groove.

[0014] Preferably, a hydraulic push rod is fixedly installed on the upper surface of the U-shaped frame, a receiving plate is installed at the output end of the hydraulic push rod, an upper mold is fixedly installed on the lower surface of the receiving plate, the back of the receiving plate is fixedly installed with the front of the fixed rack, and an insertion block is fixedly installed at the bottom of the fixed rack. After the position of the insertion block is moved down, it is just positioned to insert and limit the connection between the threaded block and the interior forming the insertion groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This tempered glass uniform pressure forming machine effectively solves the problem of glass cracking or internal stress concentration caused by excessively fast hydraulic push rod pressing speed by setting a buffer mechanism. When the receiving plate drives the upper mold to descend rapidly, the fixed rack and gear mesh to drive the cam to rotate. The cam's convex part smoothly presses down on the bonding plate, causing the compression spring and telescopic rod to gradually compress, generating a progressive buffer reaction force. This achieves soft contact between the upper mold and the glass, avoiding the impact load that is difficult to control precisely in traditional hydraulic systems. It reduces the risk of local dents, uneven thickness, or direct cracking of high-temperature softened glass due to excessive impact in the early stages of forming, thereby improving the yield and product consistency.

[0018] 2. This tempered glass uniform pressure forming machine, through the setting of a limiting splicing mechanism, completely solves the practical production problem of the upper mold being rebounded or suspended due to the buffer reaction force after soft contact, making it impossible to close the mold in place. When the fixed rack continues to descend, the rotating shaft drives the receiving rod and the bidirectional screw to rotate through pulley one, the transmission belt and pulley two, driving the two threaded blocks to approach each other and form an insertion groove, so that the insertion block at the bottom of the fixed rack is precisely inserted into the insertion groove to form a hard limit. After the buffering action is completed, this linkage structure automatically locks the compression spring, so that all the downward pressure of the hydraulic push rod can be transmitted to the upper mold without loss, forcibly completing the mold closing action, ensuring that the gap between the upper mold and the lower mold is precisely controllable, the glass is pressed to the design thickness and perfectly fits the complex curved surface, avoiding product dimensional deviations and shape defects. At the same time, the locking mechanism automatically unlocks and resets during the return stroke, without the need for additional power or electrical control, improving the reliability and automation of the device.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 , Figure 4 and Figure 5 A mechanical device for uniformly pressing and forming tempered glass includes a base 1, a U-shaped frame 8 fixedly installed on the upper surface of the base 1, and a pressing limiting mechanism installed on both the front and rear sides of the upper surface of the base 1. The power input end of the downward pressure limiting mechanism is equipped with a buffer mechanism that converts the downward pressure into engagement force, and the power output end of the buffer mechanism is equipped with a splicing mechanism that converts the converted force into reciprocating force. The downward pressure limiting mechanism consists of a buffer mechanism and a limiting splicing mechanism. The buffer mechanism includes a rotating shaft 13, a gear 14, a fixed rack 15, a cam 16, a bonding plate 17, a compression spring 18, and a telescopic rod 19. The outer surface of the rotating shaft 13 is rotatably mounted to the inner wall of the U-shaped frame 8. The inside of the gear 14 is fixedly mounted to the outside of the rotating shaft 13. The back of the fixed rack 15 meshes with the outer surface of the gear 14. The inside of the cam 16 is fixedly mounted to the outer surface of the left end of the rotating shaft 13. The upper surface of the bonding plate 17 is bonded to the outer surface of the cam 16. One end of the compression spring 19... The lower surface of the bonding plate 17 is fixedly installed, one end of the telescopic rod 19 is fixedly installed to the lower surface of the bonding plate 17, one end of the compression spring 18 is fixedly installed to the upper surface of the base 1, one end of the telescopic rod 19 is fixedly installed to the upper surface of the base 1, a rectangular groove 12 is opened inside the U-shaped frame 8, and the inside of the rectangular groove 12 is installed between the gear 14 and the gear 14. The buffer part of the cam 16 is initially attached to the upper surface of the bonding plate 17, and during the overall operation, the convex part of the cam 16 is attached to the upper surface of the bonding plate 17, and exerts downward pressure on the compression spring 18 and the telescopic rod 19.

[0023] Specifically, the rotating shaft 13 is fixedly connected to the gear 14, and the fixed rack 15 meshes with the outer surface of the gear 14, converting the downward pressure into a meshing force. Then, the cam 16 is fixedly connected to the left end of the rotating shaft 13, further converting the meshing force into a reciprocating force output. The force conversion path is clear and the transmission is stable, ensuring the smoothness of the pressure application process. The cam 16 initially adheres to the upper surface of the bonding plate 17, and during operation, the convex part adheres to the upper surface of the bonding plate 17, generating downward pressure on the compression spring 18 and the telescopic rod 19. The elastic deformation of the compression spring 18 achieves force buffering and absorption, and the telescopic rod 19 provides stable support and guidance. The two work together to change the pressure application process from rigid impact to flexible gradual pressure, reducing the risk of breakage during glass forming.

[0024] Please see Figure 1 , Figure 6 and Figure 7The limiting and splicing mechanism includes a first pulley 21, a transmission belt 22, a second pulley 23, a receiving rod 24, a double-acting screw 25, and a threaded block 26. One end of the receiving rod 24 is rotatably mounted to the inner wall of the base 1. One end of the double-acting screw 25 is fixedly mounted to one end of the receiving rod 24. The bottom inner wall of the threaded block 26 is threadedly connected to the outer surface of the double-acting screw 25. The interior of the second pulley 23 is fixedly mounted to the outer surface of the receiving rod 24. The inner ring of the transmission belt 22 is driven by the outer surface of the second pulley 23. The outer surface of the first pulley 21 is connected to the inner ring of the transmission belt 22. The drive is installed in a ring, with the inside of the pulley 21 fixedly installed to the outer surface of the rotating shaft 13. The threaded block 26 has an insertion groove 27 inside. The upper surface of the U-shaped frame 8 is fixedly installed with a hydraulic push rod 9. The output end of the hydraulic push rod 9 is provided with a receiving plate 10. The lower surface of the receiving plate 10 is fixedly installed with an upper mold 11. The back of the receiving plate 10 is fixedly installed with the front of the fixed rack 15. The bottom of the fixed rack 15 is fixedly installed with an insertion block 20. After the position of the insertion block 20 is moved down, it is just inserted and limited between the threaded block 26 and the inside of the insertion groove 27.

[0025] Specifically, through the transmission cooperation of pulley 21, transmission belt 22, pulley 23, and receiving rod 24, the rotational motion of rotating shaft 13 is stably transmitted to bidirectional screw 25, realizing the synchronous linkage of power between buffer mechanism and limit splicing mechanism. No additional power source is required, the structure is simple, the transmission is reliable, and the precise timing coordination of downward pressure and limit action is guaranteed. The bidirectional screw 25 is fixedly installed at one end with the receiving rod 24, and the inner wall of the bottom end of the threaded block 26 is threadedly connected to the outer surface of the bidirectional screw 25. When the bidirectional screw 25 rotates, it can drive the threaded blocks 26 on both sides to move relative to each other or towards each other at the same time, so that the insertion grooves 27 on the two threaded blocks 26 open or close synchronously. This allows for precise bidirectional limit control of the downward stroke of the upper mold 11, ensuring accurate alignment and uniform pressure of the upper and lower molds during the tempered glass forming process. The bottom of the fixed rack 15 is fixedly installed with an insertion block 20. At the end of the downward stroke, the insertion block 20 and the insertion groove 27 on the threaded block 26 form an insertion limit setting, which constitutes a mechanical hard limit structure. Even if the hydraulic push rod 9 is overloaded or out of control, the cooperation between the insertion block 20 and the insertion groove 27 can prevent the receiving plate 10 and the upper mold 11 from continuing to press down, effectively preventing the tempered glass from breaking due to excessive pressure, and improving the safety of equipment operation and the consistency of product forming.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The base 1 has a placement groove 6 inside, and a lower mold 7 is fixedly installed inside the placement groove 6. A receiving platform 1 2 is fixedly installed on the right side of the base 1. Multiple sets of conveyor rollers 1 3 are installed inside the receiving platform 1. A receiving platform 2 4 is fixedly installed on the left side of the base 1. Multiple sets of conveyor rollers 2 5 are installed inside the receiving platform 2 4.

[0027] Specifically, the placement groove 6 inside the base 1 provides a precise positioning and installation space for the lower mold 7, ensuring that the lower mold 7 is fixed stably and not easily shifted. This ensures the alignment accuracy between the tempered glass and the upper mold 11 during molding, reducing product defects caused by mold misalignment. The base 1 has a receiving platform 2 fixedly installed on the right side, which is equipped with multiple sets of conveyor rollers 3. The receiving platform 4 fixedly installed on the left side is equipped with multiple sets of conveyor rollers 5. This forms a complete roller conveyor system for the feeding and discharging ends. Tempered glass can smoothly enter the forming station above the placement trough 6 along the conveyor rollers 3. After forming, it can be smoothly output along the conveyor rollers 5. This realizes continuous flow operation of feeding, forming, and unloading. The setting of multiple sets of conveyor rollers 3 and multiple sets of conveyor rollers 5 makes the glass uniformly stressed and runs smoothly during the conveying process. It avoids the tilting of the glass or local stress concentration caused by single-point support. It is especially suitable for the conveying of large-area tempered glass and effectively reduces the breakage rate in the transfer process. The receiving platform 2 and receiving platform 4 are fixedly installed on the right and left sides of the base 1, respectively. Together with the U-shaped frame 8, hydraulic push rod 9 and other core forming components on the base 1, they form a symmetrical layout structure. The overall device has a compact footprint and a clear workflow. Operators can perform feeding and unloading operations from both sides at the same time, which improves the efficiency of mass production.

[0028] Working principle: During use, ordinary flat glass heated to a softened state is conveyed to the lower mold 7 in the placement groove 6 inside the base 1 via multiple sets of conveying rollers 3 within the receiving platform 2. Subsequently, the hydraulic push rod 9 on the upper surface of the U-shaped frame 8 is activated, driving the receiving plate 10 and the upper mold 11 at its output end to descend rapidly. To prevent the glass from cracking due to excessive descent speed, the fixed rack 15 on the back of the receiving plate 10 first engages with the gear 14 on the rotating shaft 13 during the initial descent, driving the cam 16 to rotate. The convex part of the cam 16 gradually presses down against the contact plate 17, generating a buffering reaction force through the compression spring 18 and the telescopic rod 19, allowing the upper mold 11 to lightly touch the glass at a low speed, achieving soft contact and preventing excessive impact. The presence of the buffering force could cause the upper mold 11 to bounce back and fail to close properly. At this time, the fixed rack 15 continues to descend, and the insertion block 20 at its bottom descends further. Simultaneously, the rotating shaft 13 transmits power to the receiving rod 24 via pulley 21, transmission belt 22, and pulley 23, driving the bidirectional screw 25 to rotate, causing the two threaded blocks 26 on its outer surface to approach each other. When the insertion block 20 is completely lowered to its lowest point, the distance between the two threaded blocks 26 decreases, forming an insertion groove 27. The insertion block 20 is just inserted into the insertion groove 27, forming a hard limit, thereby locking the buffer mechanism and preventing the compression spring 18 from rebounding. At this time, all the downward pressure of the hydraulic push rod 9 is transmitted to the upper mold 11, overcoming the buffer reaction force and precisely pressing the glass to the designed thickness. After extrusion molding is completed, the hydraulic push rod 9 drives the upper mold 11 to return, the fixed rack 15 moves upward, driving the bidirectional screw 25 to reverse, causing the two threaded blocks 26 to separate, the insertion block 20 to disengage from the insertion groove 27, and the buffer mechanism to reset. Finally, the molded glass is removed by an external robot and transported to the annealing furnace for slow cooling via the conveyor roller 25 on the receiving platform 4.

[0029] The hydraulic push rod 9 is recommended to be a tie-rod type hydraulic cylinder with a central hinge mounting, which can provide sufficient mold closing pressure and accommodate the vertical reciprocating motion of the receiving plate 10. This hydraulic cylinder is driven by hydraulic oil supplied by an external hydraulic station, which includes a motor, oil pump, solenoid directional valve, and relief valve. The solenoid valve is controlled by a PLC or relay control system to achieve the extension and retraction of the hydraulic push rod 9. The entire device is powered by a three-phase AC power supply connected to the control cabinet. The control cabinet contains a circuit breaker, contactor, transformer, and DC power module, converting 380V AC power into the power required by the hydraulic station motor. Simultaneously, it is stepped down and rectified to 24V DC power to supply control components such as proximity switches and limit sensors. The upper mold 11 and lower mold 7 should be made of heat-resistant stainless steel or heat-resistant cast iron, and their forming surfaces should be polished and coated with an anti-oxidation coating to prevent high-temperature sticking and oxidation corrosion. The cam 16, contact plate 17, compression spring 18, and telescopic rod 19 in the buffer mechanism must be made of heat-resistant alloy steel and undergo quenching and tempering treatment to ensure that they can maintain sufficient rigidity and fatigue strength under frequent compression and rebound and high-temperature radiation. Transmission and limiting components such as gear 14, fixed rack 15, double-acting screw 25, and threaded block 26 should be made of high-strength carburized steel and have their surfaces hardened and wear-resistant.

[0030] Before operating the device, the lubrication status of all moving parts must be checked, especially the surface of the telescopic rod of the hydraulic push rod 9, which should be free of scratches or rust. Simultaneously, ensure that the rotation of conveyor roller 3 and conveyor roller 5 is smooth and free of foreign objects to prevent scratching the softened glass. Before each startup, a no-load test run should be performed to observe whether the insertion block 20 can accurately insert into the insertion groove 27 formed by the two threaded blocks 26 when the receiving plate 10 drives the fixed rack 15 to rise and fall, and whether it can smoothly disengage during the return stroke. If jamming occurs, the initial position of the bidirectional screw 25 or the spacing of the threaded blocks 26 needs to be adjusted. During operation, the uniformity of the glass heating temperature and the pressure and speed parameters of the hydraulic push rod 9 must be strictly controlled to avoid crushing due to excessively low temperature or damaging the mold due to excessive pressure. Glass debris or dust around the placement groove 6 and the lower mold 7 must be cleaned regularly to prevent dust from entering the gap between the compression spring 18 and the telescopic rod 19 and affecting the buffering effect. When stopping for maintenance, the device must be waited for. After the material has cooled to room temperature, maintenance should be carried out. In particular, direct contact with high-temperature components such as mold 11 and cam 16 should be avoided while the material is in a high-temperature state. The tension of the transmission belt 22 and the keyway connection of pulley 1 21 and pulley 23 should be checked regularly to ensure long-term reliability.
