[0055] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0056] The hot bending forming workstation of the present invention is described below with reference to the accompanying drawings.

[0057] The utility model provides a hot bending forming workstation, such as Figure 1 and Figure 2 As shown, the hot bending forming workstation includes:

[0058] The heat-insulating furnace 1 has an opening 11 extending to both sides at the front end;

[0059] The lower mold assembly 2 is lifted and arranged in the heat-insulating furnace 1 and driven by the first lifting drive module 4;

[0060] The upper mold assembly 3 is lifted and arranged in the heat-insulating furnace 1 and driven by the second lifting drive module 5. The upper mold assembly 3 and the lower mold assembly 2 are arranged in a vertically aligned manner.

[0061] The hot bending and forming workstation and / or the heat-insulating furnace 1 are provided with partition doors, which at least open and close part of the openings 11 on both sides.

[0062] By arranging the lower mold group 2 and the upper mold group 3 in the heat-insulating furnace 1, and configuring a partition door that can be opened and closed in the hot bending molding workstation and / or the heat-insulating furnace 1, the furnace cavity of the heat-insulating furnace 1 can be locked and insulated to avoid excessive heat loss in the furnace cavity. In this way, it can ensure that the temperature difference distribution in the surrounding areas of the lower mold group 2 and the upper mold group 3 in the furnace is uniform, so that the mold and the glass on the mold are heated evenly when heated; at the same time, it can be convenient to carry the glass from the heat-insulating furnace 1 to the rotating drive mechanism by opening an opening 11 extending to both sides on the front side of the heat-insulating furnace 1, and setting the partition door to be openable and closed, so that the heat-insulating furnace 1 and the partition door can be rotated in and out, thereby avoiding interference of the heat-insulating furnace 1 and the partition door with the rotating drive mechanism. In summary, the heat-bending molding workstation in the utility model can be applied to turntable-type heat-bending molding equipment, and can ensure that the temperature distribution around the mold is uniform, so that the mold and the glass are heated evenly when heated.

[0063] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments of the present application, the lower mold set 2 includes a lower mold body 21, and the upper mold set 3 includes an upper mold body 31. The lower mold body 21 and the upper mold body 31 can be close to each other in the area corresponding to the opening 11 or above the corresponding area. One of the lower mold body 21 and the upper mold body 31 is a convex mold, and the other is a concave mold. Through the extrusion and engagement of the convex mold and the concave mold under a high temperature environment, a single-station molding method similar to a stamping action is formed for the workpiece (in this case, glass is used as a specific workpiece for processing, and the applicable workpiece can also be a variety of materials such as sapphire and ruby), so that the heated and softened glass is pressed into a preset shape. Specifically, when the rotary drive mechanism carries the bracket and the glass placed on the bracket into the heat-insulating furnace 1, it will stay at a preset position. At this time, the glass stays between the lower mold body 21 and the upper mold body 31. After the glass is heated and softened by the heating element, the next process is that the upper and lower molds press the glass into shape. That is, by setting the relative positions of the lower mold body 21 and the upper mold body 31 within the area corresponding to the opening 11 or above the corresponding area, the lower mold assembly 2 can be used to lift the glass a certain distance in advance before the upper and lower molds are brought together to separate the glass from the bracket, thereby avoiding damage to the bracket during the mold closing process.

[0064] In some embodiments of the present application, the upper mold body 31 and the lower mold body 21 are preferably alloy tungsten steel molds, which have high hardness and strong high-temperature oxidation resistance.

[0065] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present application, the lower mold assembly 2 includes a heating base 22 and a side heating fence 24, the side heating fence 24 surrounds the heating base 22 and forms a lower mold heating cavity 241 with the opening 11 facing upward; the lower mold body 21 is arranged on the heating base 22. When the rotary drive mechanism carries the glass and stays between the lower mold body 21 and the upper mold body 31, the lower mold body 21 can be preferentially controlled to rise a preset distance, so that the glass is carried by the lower mold body 21. Then the heating base 22 is controlled to heat the lower mold body 21, and the heat is transferred to the glass through the lower mold body 21, so as to achieve heating of the glass. By setting the side heating fence 24, the temperature around the lower mold body 21 can be locked and insulated, so as to ensure that the temperature distribution around the lower mold body 21 and the glass is uniform, and the glass is evenly heated during the heating process.

[0066] like Figure 3 and Figure 4As shown, in some embodiments of the present application, a plurality of first heating elements 23 are provided on the heating base 22, and the plurality of first heating elements 23 are distributed in different areas of the heating base 22. The first heating elements 23 may be infrared heating tubes, infrared heating sheets, resistance wires, etc. The hot bending forming workstation may further include a control unit, which may control the heating power and temperature of the first heating elements 23 in different areas. By controlling the first heating elements 23, the heating base 22 may be able to adaptively adjust the heating power of different areas according to the heating rate of different areas of the glass, thereby achieving control of the softening degree of different areas of the glass during the heating process.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, a plurality of second heating elements 25 may be arranged on the side heating fence 24, and the second heating elements 25 are used to transfer temperature to the lower mold heating cavity 241. The aforementioned control unit can also control the heating power and temperature of the second heating elements 25. In this way, the second heating elements 25 on the side heating fence 24 can be controlled to further adjust the temperature of different areas of the lower mold heating cavity 241, so as to achieve a better uniform heating effect on the glass.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, a temperature sensing element may be arranged on the heating base 22 to facilitate monitoring the heating temperature of different areas of the heating base 22. Of course, a temperature sensing element may also be arranged on the side heating fence 24 to facilitate monitoring the heating temperature of different areas of the side heating fence 24, wherein the temperature sensing element may be a thermocouple 26.

[0069] like Figure 3 As shown, in some embodiments of the present application, the heating base 22 is connected to the first lifting drive module 4 by transmission, and is adjusted to rise and fall in the lower mold heating cavity 241. That is, the heating base 22 is arranged in the lower mold heating cavity 241 and can be lifted and lowered relative to the heating fence 24. By connecting the heating base 22 to the first lifting drive module 4 by transmission, the lower mold body 21 can be conveniently lifted to lift the glass on the bracket, and the pressed and formed glass can be conveniently placed on the bracket.

[0070] like Figure 2 and Figure 3As shown, in some embodiments of the present application, the hot bending forming workstation may further include a frame 6, on which a mounting plate 61 is provided, and a first lifting drive module 4 includes a first lifting fixed seat 41 fixedly provided at the bottom of the mounting plate 61, a first movable seat 42 slidably matched with the first lifting fixed seat 41, and a first driving assembly 43 provided between the first lifting fixed seat 41 and the first movable seat 42.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a sealing plate 46 is also sleeved on the support connecting column 45, and a sealing gasket 47 is provided between the sealing plate 46 and the support connecting column 45, and the sealing plate 46 is used to be fixedly installed on the bottom of the mounting plate 61. In order to avoid oxidation of the mold, the thermal insulation furnace 1 or the entire workstation located above the frame 6 needs to be in a closed environment. By filling the closed environment with nitrogen, the oxidation of the mold can be slowed down, and by providing the sealing plate 46 and the sealing gasket 47, the nitrogen in the closed environment can be prevented from leaking from the gap between the support connecting column 45 and the mounting plate 61.

[0072] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the lower mold assembly 2 further includes a fixed bottom enclosure 27, and the side heating fence 24 is installed on the bottom enclosure 27. The bottom enclosure 27 is a heat insulation board and is sealed at the bottom opening of the lower mold heating cavity 241. Specifically, the bottom enclosure 27 is fixedly installed on the upper end of the mounting plate 61 by high-temperature screws, and the side heating fence 24 can be installed on the bottom enclosure 27 or directly on the mounting plate 61. The supporting connecting column 45 movably passes through the mounting plate 61 and the bottom enclosure 27 and is fixedly connected to the heating base 22 in the lower mold heating cavity 241. In this setting form, by setting the bottom enclosure 27 as a heat insulation board, not only can the heat loss in the lower mold heating cavity 241 be reduced, but also the bottom of the lower mold heating cavity 241 can be insulated to prevent the temperature in the lower mold heating cavity 241 from being transferred to the first lifting drive module 4 or other components under the frame 6.

[0073] In some embodiments of the present application, the supporting connecting column 45 is a hollow column and a water cooling pipe A is arranged inside to further reduce the heat transferred from the lower mold heating cavity 241 to the first lifting drive module 4.

[0074] In some embodiments of the present application, a nitrogen filling pipeline B for filling nitrogen may also be provided on the bottom enclosure 27 and the furnace wall of the upper furnace body 12 .

A plurality of third heating elements 33 are arranged on the upper heating plate 324 and / or the base side plate 323, and the control unit can also control the working condition and heating power of the third heating element 33. In this way, the temperature distribution in the upper mold heating cavity 321 can be ensured to be uniform through the plurality of third heating elements 33, so that the upper mold body 31 is evenly heated, and the temperature of different areas of the upper mold body 31 is controlled. So that when the upper and lower molds are pressed together, the curvature of the curved surface of the glass can be better controlled.

[0079] like Figure 2 and Figure 5As shown, in some embodiments of the present application, the second lifting drive module 5 includes a second lifting fixed seat 51 that is fixedly arranged, a second movable seat 52 that is lifted and slidably matched with the second lifting fixed seat 51, and a second driving assembly 53 that is arranged between the second lifting fixed seat 51 and the second movable seat 52.
