Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass hot bending auxiliary devices, and more particularly to glass hot bending extrusion forming auxiliary devices. Background Technology
[0002] In the glass hot bending process, the core step is to heat the glass to a softened state and then hot-press it into shape using a mold, so that the glass forms a curved shape that meets the design requirements. Currently, the hot bending molds commonly used in the industry are prefabricated fixed welded structures. The core forming component, which is the contact component used to support and compress the softened glass, is usually integrated with the mold body. This structure determines that the spacing between the forming components is fixed and cannot be adjusted.
[0003] The integrated welding design means that the spacing between the forming components is fixed and cannot be adjusted, which leads to a series of problems: because the spacing is fixed, each mold can only correspond to a glass product with one bending diameter. When changing specifications, the entire mold needs to be replaced, which severely limits production flexibility. To cover multiple specifications, companies need to design and manufacture molds separately for each bending diameter, which increases the initial design and manufacturing costs, as well as additional storage and maintenance costs. Small-batch customized orders have even higher costs due to the special nature of the molds, resulting in low economic efficiency. Furthermore, each mold change requires machine shutdown, disassembly and installation, and repositioning, temperature calibration and other adjustments, which prolongs production downtime and increases the overall cycle time, making it difficult to meet the market's demand for rapid response to multiple specifications of products. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary device for hot bending and extrusion molding of glass in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glass hot bending extrusion forming auxiliary device, including a fixed frame and a support frame fixed at its lower part, a variable distance limiting component is slidably arranged on the fixed frame, a bidirectional driving component for driving the variable distance limiting component is arranged on one side of the fixed frame, and a return component is installed on the fixed frame below the variable distance limiting component. The variable pitch limiting component includes symmetrically opened slide grooves on both sides of the fixed frame, and rollers that slide between the two slide grooves respectively. The return assembly includes a quartz fiber cloth elastically disposed on the lower side of the two slides.
[0006] As a further description of the above technical solution: the roller includes a support rod and sliders that are fixedly installed at both ends of the support rod and slide between two grooves.
[0007] As a further description of the above technical solution: a rolling sleeve is rolled on the outer side of the support rod.
[0008] As a further description of the above technical solution: the bidirectional drive assembly includes a guide rail box fixed to one side of the fixed frame, and a threaded sliding member that is fixedly connected to the support rod on the same side is slidably installed on the inner side of the guide rail box. A partition seat is fixedly connected to the middle of the inner side of the guide rail box, and rotating seats are symmetrically installed on the two sides of the inner side of the guide rail box away from the middle.
[0009] As a further description of the above technical solution: the bidirectional drive assembly also includes a servo motor fixed on one side of the fixed frame, and two lead screws with opposite directions are rotatably installed between the separator and the two rotating seats respectively. The inner sides of the two rotating seats are threadedly connected to the outer sides of the two lead screws respectively, and the output shaft of the servo motor is fixedly connected to the rotating shaft relative to the lead screw through a coupling.
[0010] As a further description of the above technical solution: the return component also includes a number of hook springs installed in a rectangular array on both sides of the top of the fixed frame, and a number of fixing rings are installed through the outer rectangular array of the quartz fiber cloth away from the axis, and the side of the hook springs away from the fixed frame is respectively hung in the number of fixing rings.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This glass hot bending extrusion forming auxiliary device addresses the structural defects of traditional glass hot bending molds, which are prefabricated and fixed by welding. It innovatively designs adjustable rollers. When the heated and softened glass is placed on two rollers for hot pressing, the two rollers are driven to move closer or further apart by a bidirectional drive component, thereby adjusting the distance between the two rollers. In this way, the bending diameter of the glass after forming can be adjusted by the variable-pitch rollers during hot pressing. This allows the same device to adapt to glass products with multiple bending diameters, completely breaking the limitation of traditional molds that are used for only one specification, improving production flexibility, and reducing the cost of mold making.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] like Figure 1 As shown, the glass hot bending extrusion forming auxiliary device provided by this utility model includes a fixed frame 1 and a support frame 2 fixed at its lower part. A variable distance limiting component 3 is slidably arranged on the fixed frame 1. A bidirectional driving component 4 for driving the variable distance limiting component 3 is arranged on one side of the fixed frame 1. A return component 5 is installed on the fixed frame 1 below the variable distance limiting component 3.
[0016] In actual use, this solution first uses the bidirectional drive component 4 to drive and adjust the limiting distance of the variable distance limiting component 3 on the fixed frame 1, thereby changing the support shape and force of the variable distance limiting component 3 on the glass depression area when hot pressing the glass; after the glass is hot pressed and formed, the return component 5 applies an upward pushing force to the glass depression area to smoothly push out the formed glass.
[0017] Specifically, such as Figure 2 and Figure 4 As shown, the variable pitch limiting component 3 includes symmetrically opened slide grooves 31 on both sides of the fixed frame 1, and rollers 32 that slide between the two slide grooves 31 respectively. The rollers 32 include support rods 321 and sliders 322 that slide between the two slide grooves 31 are fixedly installed at both ends of the support rods 321. Rolling sleeves 323 are rolled on the outside of the support rods 321. The two rollers 32 are driven to move closer or further apart by the bidirectional drive assembly 4, thereby adjusting the distance between the two rollers 32. In this way, the bending diameter of the glass after forming can be adjusted by the variable-pitch rollers 32 during hot pressing. When the glass is bent downwards, its lower surface comes into contact with the rolling sleeve 323 that rolls on the outside of the support rod 321. When the glass bends and sinks, it causes the rolling sleeve 323 to rotate around the support rod 321, reducing the rigid support stress of the support rod 321 on the glass.
[0018] Furthermore, such as Figure 1 and Figure 3 As shown, the bidirectional drive assembly 4 includes a guide rail box 41 fixed to one side of the fixed frame 1. The inner side of the guide rail box 41 is slidably installed with a threaded nut slide 44 fixedly connected to the support rod 321 on the same side. The middle of the inner side of the guide rail box 41 is fixedly connected to a partition seat 42. Rotary seats 421 are symmetrically installed on the two sides of the inner side of the guide rail box 41 away from the middle. The bidirectional drive assembly 4 also includes a servo motor 45 fixed on one side of the fixed frame 1. Two lead screws 43 with opposite directions are rotatably installed between the partition seat 42 and the two rotating seats 421. The inner sides of the two rotating seats 421 are threadedly connected to the outer sides of the two lead screws 43 respectively. The output shaft of the servo motor 45 is fixedly connected to the rotating shaft relative to the lead screws 43 through a coupling. When the servo motor 45 is started to rotate forward, the servo motor 45 drives the two lead screws 43 with opposite directions to rotate together. This causes the threaded nut slides 44 on the two lead screws 43 to drive the two rollers 32 to move closer to each other. Conversely, when the servo motor 45 rotates forward, it drives the two rollers 32 to move away from each other.
[0019] Furthermore, such as Figure 2 and Figure 5 As shown, the return assembly 5 includes a quartz fiber cloth 52 elastically disposed on the lower side of the two slides 31; The return assembly 5 also includes a number of hook springs 51 mounted in a rectangular array on both sides of the top of the fixed frame 1. A number of fixing rings 521 are installed through the rectangular array of the quartz fiber cloth 52 away from the axis. The side of the hook springs 51 away from the fixed frame 1 is respectively hung in the fixing rings 521. When the glass bends downwards, after it is released from the quartz fiber cloth 52, several hook springs 51 are pulled downwards together. After the glass is hot-pressed, several hook springs 51 lose their supporting force and pull the quartz fiber cloth 52 back to its original position, pushing the formed glass to the top of the fixed frame 1.
[0020] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
