Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a lifting device based on a fragile structure and glass processing equipment. Background Art

[0002] The difficulty in the production process of curved glass is the hot pressing forming process. As disclosed in the Chinese invention patent application with application number 201611190903.6, in the general hot pressing forming process, the flat glass blank needs to be preheated, hot pressed and cooled in a hot bending furnace in sequence to form it. In this process, a graphite mold is required for carrying, conveying and mold closing. However, the graphite mold has defects during use. Specifically, the graphite mold is prone to collision when the mold is closed. That is, when the upper mold and the lower mold contact the joint mold during use, the impact force is too large and it is easy to be damaged, which makes the graphite mold prone to wear and tear, affecting the overall service life of the graphite mold. For example, the Chinese invention patent application with application number 201922097434.9 A new utility model patent application is applied for, which is equipped with a slide groove, a buffer block and a buffer pad to buffer the pressure plate, and will not cause large wear between the upper and lower molds of the graphite mold. However, it is necessary to modify and adjust the mold used for each specification of curved glass products, and its universality is poor. For example, the Chinese utility model patent application with application number 202122540737.0 installs a buffer structure on both sides of the bottom end of the graphite upper mold, which reduces the friction and collision force of the upper and lower molds of the graphite mold when the mold is closed, thereby improving the overall protection of the graphite mold, but it also requires modification and adjustment of the mold used for each specification of curved glass products, and its universality is poor.

[0025] The above-mentioned lifting device based on the fragile structure enables the first pressure-regulating valve to be connected to the first air port of the cylinder, and further cooperates with the solenoid valve to be connected to the second air port of the cylinder, and the second pressure-regulating valve to be connected to the solenoid valve, so that the cylinder can realize real-time control of the pressure difference between its corresponding first air port and the second air port through the cooperation of the solenoid valve, the first pressure-regulating valve and the second pressure-regulating valve, so that the power output end of the cylinder can reduce the pressure difference between the first air port and the second air port of the cylinder to 0.01MPa at the moment of driving the mold to close the mold. At this time, the power output end of the cylinder stops extending further, thereby effectively reducing the wear of the mold, and has a simple structure. The lifting device based on the fragile structure can be adapted to various molds, thereby effectively reducing the wear of graphite molds used for processing curved glass of various specifications.

[0026] In order to better understand the lifting device based on the fragile structure of the present application, the lifting device based on the fragile structure of the present application is further explained below:

[0027] Please also refer to Figures 1 to 3In one embodiment, a lifting device 10 based on a fragile structure includes a cylinder 100 and a cylinder pressure difference regulating assembly 200. The cylinder 100 is provided with a first air inlet 101 and a second air inlet 102. The first air inlet 101 is arranged near the power output end of the cylinder 100, and the second air inlet 102 is arranged on the side of the first air inlet 101 away from the power output end of the cylinder 100. The power output end of the cylinder 100 is used to connect a carrier, and the carrier includes at least a mold 20. The cylinder pressure difference regulating assembly 200 includes a solenoid valve 210, a first pressure regulating valve 220 and a second pressure regulating valve 230. The first pressure regulating valve 220 is connected to the first air inlet 101, the solenoid valve 210 is connected to the second air inlet 102, and the second pressure regulating valve 230 is connected to the solenoid valve 210. Furthermore, the power output end of the cylinder 100 is connected to at least a portion of the mold 20 , and further, the power output end of the cylinder 100 is connected to the upper mold of the mold 20 , for driving the upper mold to move toward the lower mold to achieve mold closing of the mold 20 .

[0028] The lifting device 10 based on the fragile structure enables the first pressure regulating valve 220 to be connected to the first air inlet 101 of the cylinder 100, and further cooperates with the solenoid valve 210 to be connected to the second air inlet 102 of the cylinder 100, and the second pressure regulating valve 230 to be connected to the solenoid valve 210, so that the cylinder 100 can achieve real-time control of the pressure difference between its corresponding first air inlet 101 and the second air inlet 102 through the cooperation of the solenoid valve 210, the first pressure regulating valve 220 and the second pressure regulating valve 230, so that the power output end of the cylinder 100 can reduce the pressure difference between the first air inlet 101 and the second air inlet 102 of the cylinder 100 to 0.01 MPa at the moment when the mold is closed. At this time, the power output end of the cylinder 100 stops extending further, thereby effectively reducing the wear of the mold, and the structure is simple. The lifting device 10 based on the fragile structure can be adapted to various molds, thereby effectively reducing the wear of graphite molds for processing curved glass of various specifications.

[0029] In one embodiment, when the power output end of the cylinder retracts, the retraction force of the cylinder decreases from greater than the gravity of the load to at least equal to the gravity of the load; and when the power output end of the cylinder extends, the extension force of the cylinder decreases from greater than 0.01 MPa to equal to 0.01 MPa. It can be understood that the cylinder controls the pressure difference between the corresponding first air port and the second air port through the solenoid valve, the first pressure regulating valve and the second pressure regulating valve, thereby realizing real-time and precise control of the extension and retraction of the cylinder. Specifically, when the pressure difference between the first air port and the second air port is controlled to cause the extension force of the cylinder to be greater than 0.01 MPa, the power output end of the cylinder continues to extend. Further, when the pressure difference between the first air port and the second air port is controlled to cause the cylinder to drive the mold to close, the extension force of the cylinder is reduced to 0.01 MPa. At this time, the power output end of the cylinder stops extending further, thereby effectively reducing the wear of the mold. In addition, when the pressure difference between the first air port and the second air port is controlled to cause the retraction force of the cylinder to be greater than the gravity of the load, the power output end of the cylinder continues to retract. Further, when the pressure difference between the first air port and the second air port is controlled to cause the retraction force of the cylinder to be reduced to equal to or greater than the gravity of the load, the power output end of the cylinder is completely retracted.

[0030] In one embodiment, when the power output end of the cylinder is extended until the extension force decreases to 0.01 MPa, the extension force of the cylinder is reduced from 0.01 MPa to 0. It can be understood that when the pressure difference between the first and second air inlets is controlled to be 0, the extension force of the cylinder is 0. This effectively reduces the operating intensity of the solenoid valve, the first pressure regulating valve, and the second pressure regulating valve, further reducing energy consumption and better ensuring the stability of mold clamping.

[0031] In one embodiment, the first pressure regulating valve is a precision pressure regulating valve. Further, in one embodiment, the second pressure regulating valve is a precision pressure regulating valve, which better ensures accurate control of the pressure difference between the first air inlet and the second air inlet of the cylinder.

[0032] In one embodiment, the cylinder is further provided with a pressure relief hole, which is connected to the first air inlet and the second air inlet respectively, so that excess gas in the cylinder is discharged from the pressure relief hole, thereby better maintaining the constant pressure of the first air inlet and the second air inlet.

[0033] Please also refer to Figures 1 to 3 In one embodiment, the lifting device 10 based on the fragile structure further includes a mounting frame 300, and the cylinder 100, the solenoid valve 210, the first pressure regulating valve 220 and the second pressure regulating valve 230 are connected to the mounting frame 300 at intervals.

[0034] In one embodiment, the mounting frame is an alloy mounting frame, which better ensures the installation stability of the cylinder, the solenoid valve, the first pressure regulating valve and the second pressure regulating valve.

[0035] In one embodiment, the mold is a graphite mold.

[0036] The present application also provides a glass processing device. One embodiment of the glass processing device includes a workbench and a lifting device based on a fragile structure of any of the above embodiments, wherein a cylinder, a solenoid valve, a first pressure regulating valve and a second pressure regulating valve are arranged on the workbench at intervals.

The cylinder 100 is provided with a first air inlet 101 and a second air inlet 102. The first air inlet 101 is arranged near the power output end of the cylinder 100, and the second air inlet 102 is arranged on the side of the first air inlet 101 away from the power output end of the cylinder 100. The power output end of the cylinder 100 is used to connect the carrier, and the carrier includes at least a mold 20. The cylinder pressure difference regulating assembly 200 includes a solenoid valve 210, a first pressure regulating valve 220 and a second pressure regulating valve 230. The first pressure regulating valve 220 is connected to the first air inlet 101, the solenoid valve 210 is connected to the second air inlet 102, and the second pressure regulating valve 230 is connected to the solenoid valve 210.

[0038] Compared with the prior art, the present invention has at least the following advantages:

[0039] The lifting device 10 based on the fragile structure of the present invention enables the first pressure regulating valve 220 to be connected to the first air inlet 101 of the cylinder 100, and further cooperates with the solenoid valve 210 to be connected to the second air inlet 102 of the cylinder 100, while the second pressure regulating valve 230 is connected to the solenoid valve 210, so that the cylinder 100 can achieve real-time control of the pressure difference between its corresponding first air inlet 101 and the second air inlet 102 through the cooperation of the solenoid valve 210, the first pressure regulating valve 220 and the second pressure regulating valve 230, so that the power output end of the cylinder 100 can reduce the pressure difference between the first air inlet 101 and the second air inlet 102 of the cylinder 100 to 0.01 MPa at the moment when the mold is closed. At this time, the power output end of the cylinder 100 stops extending further, thereby effectively reducing the wear of the mold.
