Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, specifically referring to a glass processing hot bending device. Background Technology

[0002] Traditional glass processing primarily uses flat glass, mainly to meet basic needs such as architectural lighting and everyday utensils. However, with the development of industrial technology, many fields have put forward requirements for the "curved" form of glass. Glass is a typical amorphous material with a unique "glass transition" characteristic: it is a rigid solid at room temperature, but when heated to a specific temperature, it gradually loses its rigidity and exhibits viscoelasticity (plasticity). At this point, it can be bent into a predetermined curved surface by external force (such as mold pressure or gravity); after cooling, the glass regains its rigidity and the curved shape is fixed.

[0003] Existing technology for hot bending glass involves placing the glass on a mold and heating it inside a furnace. After the glass is bent, the supporting part in the middle of the mold is lifted and removed. However, once the mold is detached, the edges of the glass are prone to losing support, which can cause slight deformation during cooling and affect the quality of the finished hot-bent glass. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a glass processing hot bending device to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: A glass processing hot bending device is proposed, including a furnace body, the top of which is provided with a liftable sealed furnace cover, and a gantry crane is provided outside the furnace body for lifting the sealed furnace cover and removing it from above the furnace body; a bending mold assembly, including a fixed mold set at the bottom of the furnace body, a movable mold set inside the fixed mold, and the movable mold being fixedly connected to the top of the sealed furnace cover by a lifting cable; both the fixed mold and the movable mold include several support ribs arranged in an arc shape; wherein, the support ribs at the joint between the movable mold and the fixed mold are arranged in an alternating pattern of lengths, and the long end of the support rib of the movable mold is used to provide additional support points during lifting.

[0006] Furthermore, ground rails are provided on both sides of the furnace body, the bottom sides of the gantry crane slide on the ground rails, guide rails are provided on the front and back of the inner side of the gantry crane, and guide rollers are provided on the front and back of both sides of the outer side of the sealed furnace cover, and the sealed furnace cover moves on the guide rails via the guide rollers.

[0007] Furthermore, the fixed mold includes a base plate, and several evenly distributed first support rods are fixedly connected to the front and back surfaces of the base plate. The first support rods are fixedly connected to the bottom of the support ribs of the fixed mold, respectively.

[0008] Furthermore, the movable mold includes a splicing base pad, and a plurality of evenly distributed second support rods are fixedly connected to the surface of the splicing base pad. The other end of the second support rods connected to the splicing base pad is fixedly connected to the bottom of the support ribs of the movable mold.

[0009] Furthermore, a positioning groove is provided at the top center of the base plate for use with the splicing base pad. After the splicing base pad and the positioning groove are spliced ​​together, the movable mold and the fixed mold are connected.

[0010] Furthermore, when the gantry crane is fully lifted, the movable mold is located above the opening at the top of the furnace body. Beneficial effects

[0011] When the furnace lid is lifted, the movable mold, which is part of the bending mold assembly used for hot bending of the glass, is also lifted. The joints of the support ribs of the movable mold and the fixed mold are not flush. After the movable mold is lifted, the protruding part of the support ribs of the movable mold can provide additional support points for the glass after it is bent and cooled, protecting the glass from cooling and forming after hot bending, and making the hot bending operation more convenient.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0021] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0022] like Figures 1-6 As shown in the figure, this utility model provides a hot bending device, particularly a glass processing hot bending device, including a furnace body 1, a bending mold assembly 2, a sealed furnace cover 3, a gantry crane 4, a fixed mold 5, a movable mold 6, and supporting ribs 8. A liftable sealed furnace cover 3 is provided on the top of the furnace body 1. A fixed mold 5 is provided inside the furnace body 1, with supports at both ends. A detachable movable mold 6 is provided in the middle of the fixed mold 5. Both the movable mold 6 and the fixed mold 5 have several supporting ribs 8 arranged in an arc shape on their tops. The supporting ribs 8 of the movable mold 6 and the fixed mold 5 are joined in such a way that adjacent supporting ribs 8 are staggered along their distribution direction, with one longer and one shorter rib on the movable mold 6. This allows the movable mold 6 to provide edge support points for the hot-bent glass after it is detached from the fixed mold 5, ensuring proper cooling and shaping of the glass after hot bending. Meanwhile, the fixed mold 5 and the movable mold 6 can be separated, which can also reduce the additional load after the sealed furnace cover 3 is lifted, reduce the lifting weight, and extend the service life of the bottom lifting cable 7 of the sealed furnace cover 3.

[0023] The fixed mold 5 also includes a base plate 501 that contacts the bottom of the furnace body 1. Several evenly distributed first support rods 502 are fixedly connected to the front and back of the upper surface of the base plate 501. The upper ends of the first support rods 502 are fixedly connected to the bottom of the support ribs 8 of the fixed mold 5, supporting the support ribs 8 of the fixed mold 5, and working together with the arched support rods at the bottom of the support ribs 8 for support. The movable mold 6 also includes a splicing base pad 601. Several second support rods 602 are also fixedly connected to the upper surface of the splicing base pad 601. The top ends of the second support rods 602 are fixedly connected to the bottom of the support ribs 8 of the movable mold 6. To expedite the splicing of the movable mold 6 and the fixed mold 5, a positioning groove 12 is formed in the middle of the surface of the base plate 501. After the splicing base pad 601 is placed inside the positioning groove 12, the movable mold 6 and the fixed mold 5 are successfully spliced.

[0024] A gantry crane 4 is installed on the outside of the furnace body 1. Ground rails 9 are installed on both sides of the bottom of the furnace body 1. The bottom of the gantry crane 4 moves back and forth along the ground rails 9. The lifting mechanism of the gantry crane 4 is connected to the top of the sealed furnace cover 3 to lift the sealed furnace cover 3 upward. As the sealed furnace cover 3 is lifted, the movable mold 6 is also lifted. When the height of the sealed furnace cover 3 exceeds that of the furnace body 1, the gantry crane 4 is pushed to lift the movable mold 6 out of the furnace body 1 and then lower the movable mold 6 to the ground. Guide rails 10 are installed on the front and back of both sides inside the gantry crane 4. Guide rollers 11 are fixedly connected to the front and back of both sides outside the sealed furnace cover 3. The guide rollers 11 are locked on the guide rails 10 to ensure that the sealed furnace cover 3 can only move up and down along the gantry crane 4.
