Description

Technical Field

[0001] The present application relates to the technical field of hot pressing and forming, and in particular to a heat preservation module, a hot pressing and forming mechanism and a hot bending machine. Background Art

[0002] When preparing glass products through the hot pressing molding process, the workpiece needs to be placed in the mold. The mold is first heated by the mold heating unit in the hot bending machine to increase the mold temperature and soften the workpiece inside the mold. The preheated workpiece is then hot pressed by the molding mechanism to match the shape of the workpiece with the shape of the mold cavity.

[0003] See also Figure 1 In the production process, the mold heating unit usually heats the upper and lower surfaces of the mold 7 by using the upper heating module 4 and the lower heating module 5 which are arranged relatively to each other, and then pressurizes the mold 7 by using the lifting module 6. When the upper heating module 4 and the lower heating module 5 are attached to the mold 7, there is a gap between the upper heating module 4 and the lower heating module 5. Due to the heat transfer between the mold 7 and the air in the gap, it is very easy to cause the temperature of the head and tail ends of the mold 7 to drop due to heat dissipation, resulting in a large temperature difference between the two ends and the middle of the mold 7, which cannot meet the heating uniformity requirements during the hot pressing process, resulting in extremely poor molding effect of the glass workpiece.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0043] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0044] In order to solve the technical problem in the prior art that the mold 7 is prone to temperature difference due to heat dissipation in local areas, resulting in poor forming effect of the hot pressing workpiece, the present application provides a thermal insulation module, a hot pressing forming mechanism and a hot bending machine, which can block the heat dissipation path through the thermal insulation module, actively heat the local area of ​​the mold 7 through the heating element 2, so that the overall temperature of the mold 7 is balanced, meeting the temperature uniformity requirements during the hot pressing process.

[0045] See also Figures 1 to 11 In the first aspect of the embodiment of the present application, there is provided a heat preservation module, including a heat preservation component 1, a heating component 2 and a temperature detection component 3. The heat preservation component 1 is made of a high temperature resistant heat insulation material, such as calcium silicate. The structure of the heat preservation component 1 can be a plate-like structure or a block-like structure, which can block the gap between the upper heating module 4 and the lower heating module 5, cut off the heat dissipation path of the mold 7, prevent the heat at the end or edge of the mold 7 from being dissipated outward along the gap, and prevent the end or edge of the mold 7 from rapidly cooling due to the heat conduction effect. The heating component 2 is arranged on one side of the heat preservation component 1, and the heating component 2 extends along the length direction of the heat preservation component 1. The heating component 2 is arranged toward the part to be insulated, such as the mold 7. When the temperature at the end or edge of the mold 7 is relatively low, the heating component 2 can actively and uniformly heat the end or edge of the mold 7 by radiating heat, so that the temperature at the end or edge of the mold 7 is maintained at the same temperature as the middle of the mold 7, so that the overall temperature of the mold 7 is balanced. The temperature detecting element 3 is connected to or arranged relative to the heating element 2, and can realize temperature measurement by contact or non-contact method, and is used to detect the temperature of the heating element 2, so as to facilitate power control of the heating element 2, so that the temperature of the heating element 2 and the mold 7 is maintained within a preset temperature range, meeting the temperature requirements of each process in the hot bending process.

[0046] It should be noted that if only partitions or insulation materials are set at the ends or around the upper heating module 4 to block the temperature dissipation of the mold 7, there will still be a temperature difference of 15 to 20°C between the edge and the center area of ​​the mold 7. While the present application blocks the temperature dissipation path through the insulation component 1, it also actively and evenly heats the edge or both ends of the mold 7 through the heating component 2, which can reduce the overall temperature difference of the mold 7 to 0 to 5°C, which is beneficial to ensure the overall temperature balance of the mold 7.

[0047] It should be noted that the power cables of the temperature detection component 3 and the heating component 2 are connected to the controller signal of the hot pressing forming mechanism, so as to facilitate feedback adjustment of the heating temperature of the heating component 2 through the temperature detection signal. The temperature detection component 3 can measure the temperature of the heating component 2 by contact and non-contact methods. Since the temperature in the furnace of the hot bending machine is high during the hot bending process, in order to avoid damage to the temperature detection component 3 caused by high temperature, it is preferred to use a thermocouple as the temperature detection component 3, and realize temperature detection by contacting the thermocouple with the heating component 2.

[0048] In the above embodiment, since the heating element 2 generates high temperature when working and the heat-insulating element 1 is made of insulating material, it is not convenient to connect the heat-insulating element 1 and the heating element 2 by bolt connection, welding or the like.

[0049] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 A mounting groove 11 is provided on one side of the thermal insulation component 1, and the heating component 2 is embedded in the mounting groove 11, so that the connection between the thermal insulation component 1 and the heating component 2 can be realized. The heating component 2 is limited by the mounting groove 11 to prevent the heating component 2 from falling off the thermal insulation component 1 during use of the thermal insulation module.

[0050] In some embodiments of this application, please refer to Figure 2 and Figure 3 Lead grooves 12 are provided at both ends of the insulation component 1 in the length direction. The power cable of the heating component 2 passes through the lead grooves 12, which is convenient for laying the power cable and connecting the heating component 2 to an external power source, so that the heating component 2 converts electrical energy into thermal energy.

[0051] In the above embodiment, the shape of the heating element 2 matches the inner wall of the mounting groove 11. Figure 2 and Figure 3 In some embodiments of the present application, the heating element 2 is a heating rod or a spiral tubular resistance wire.

[0052] In some embodiments of the present application, the heating rod includes a metal shell and a resistance wire arranged inside the metal (such as stainless steel, copper, etc.) shell. The resistance wire and the metal shell are filled with an insulating material with thermal conductivity. The resistance wire generates heat, transfers the heat to the metal shell, and then radiates the heat to the mold 7 through the metal shell. Figure 2 and Figure 6 shown.

[0053] In other embodiments of the present application, the spiral tubular resistance wire is a tubular heating structure formed by winding the resistance wire in a spiral shape. When the resistance wire is energized, heat is generated and the heat is radiated directly to the mold 7 through the resistance wire. Figure 3 and Figure 7 shown.

[0054] The second aspect of the embodiment of the present application provides a hot pressing forming mechanism, including the insulation module described in the above embodiment, and also including an upper heating module 4 and a lower heating module 5 arranged relatively to each other, and insulation modules are provided at both ends of the upper heating module 4 and / or both ends of the lower heating module 5. The upper heating module 4, the insulation component 1 and the lower heating module 5 enclose a heating space, and the heating component 2 is arranged toward the heating space, and is used to insulate and heat the mold 7 inside the heating space, so as to realize all-round preheating and insulation of the mold 7. Figure 8 and Fig.11 shown.

[0055] Specifically, when the heat preservation module is arranged on the upper heating module 4, at least two heat preservation modules are arranged at the two ends of the upper heating module 4 to heat the head and tail ends of the mold 7. The bottom of the heat preservation member 1 is arranged to protrude from the bottom of the upper heating module 4, which can be used to block the gap between the upper heating module 4 and the lower heating module 5 to prevent heat from radiating outward. The heating member 2 is located on the side of the heat preservation member 1 close to the upper heating module 4, which can be used to achieve radiation heating of the mold 7 below the upper heating module 4, such as Figure 4 and Figure 8 shown.

[0056] It should be noted that due to the large temperature difference between the head and tail ends of the mold 7, Figure 4 and Figure 8 It is only indicated that the insulation modules are arranged at both ends of the mold 7, but if the left and right sides of the mold 7 also need to be insulated, the insulation modules of the present application can be arranged around the upper heating module 4, which is not limited here.

[0057] In some embodiments of this application, please refer to Fig.10When insulation modules are provided at both ends of the lower heating module 5, the top of the insulation member 1 protrudes from the top of the lower heating module 5, and can be used to block the gap between the upper heating module 4 and the lower heating module 5. In order to prevent the insulation module from blocking the movement of the mold 7 inside the hot pressing molding mechanism, the length direction of the insulation member 1 is parallel to the movement direction of the mold above the lower heating module 5, so that the insulation modules are located on both sides of the movement direction of the mold 7, and the mold 7 is kept warm and heated while avoiding affecting the movement of the mold 7.

[0058] It should be noted that the insulation module can be set separately on the upper heating module 4 or the lower heating module 5, or the insulation modules can be set on both the upper heating module 4 and the lower heating module 5 at the same time to ensure that the heating space can at least form uniform heating and insulation for the head and tail ends of the mold 7.

[0059] In some embodiments of this application, please refer to Figure 5 , Figure 6 and Fig. 9 The upper heating module 4 and the lower heating module 5 each include a heating plate and a plurality of heating elements, wherein the heating plate is made of a high-strength, high-temperature-resistant heat-conducting material, and can achieve uniform heat conduction to the mold 7. The plurality of heating elements are inserted into the mounting holes of the heating plate, and are used to convert electrical energy into thermal energy, and transfer the heat to the mold 7 through the upper heating plate, so as to preheat the mold 7.

[0060] It should be noted that multiple heating elements are evenly arranged along the length or width direction of the heating plate, and the heating power of the multiple heating elements can be independently controlled, so that the heating power of the heating element at the edge of the heating plate can be higher than the heating power of the heating element in the center area of ​​the heating plate, which is beneficial to reducing the overall temperature difference of the mold 7.

[0061] As a specific embodiment of the present application, the upper heating module 4 includes an upper heating plate 41 and a plurality of first heating elements 42. Five first heating elements 42 are sequentially arranged along the width direction of the upper heating plate 41. The first heating element 42 is a heating rod or a heating tube. The length direction of the first heating element 42 is parallel to the length direction of the upper heating plate 41 and the length direction of the mold 7. Since the temperature difference in the width direction of the mold 7 can be adjusted by adjusting the power of the first heating element 42 (that is, the heat generation of the first heating elements 42 on both sides of the width direction of the upper heating plate 41 can be increased to achieve the temperature difference adjustment in the width direction of the mold 7), at this time, only the insulation modules need to be arranged at both ends of the length direction of the upper heating plate 41 to adjust the temperature difference generated in the length direction of the mold 7. Through the combined action of the plurality of first heating elements 42 and the insulation module, the temperature difference between the edge of the mold 7 and its central area can be adjusted.

[0062] In some embodiments of this application, please refer to Fig. 9The lower heating module 5 includes a lower heating plate 51, a plurality of second heating elements 52 and a support seat 53. The lower heating plate 51 is arranged on the support seat 53. The plurality of second heating elements 52 are sequentially arranged along the length or width direction of the lower heating plate 51 to achieve uniform heating of the bottom of the mold 7.

[0063] As a specific embodiment of the present application, six second heating elements 52 are evenly arranged along the width direction of the lower heating plate 51. When the upper heating plate 41 and the lower heating plate 51 are arranged relative to each other, the first heating element 42 and the second heating element 52 are staggered with each other, that is, in the vertical direction, the first heating element 42 and the interval area between two adjacent second heating elements 52 are arranged relative to each other, so that the mold 7 can be evenly heated as a whole. Figure 4 shown.

[0064] It should be noted that the upper heating module 4 and the lower heating module 5 are both provided with corresponding detection elements, and the temperature of the upper heating module 4 and the lower heating module 5 can be adjusted according to the temperature detection information. Figure 4 Specifically, the upper heating module 4 is provided with a first detection element 43 and the lower heating module 5 is provided with a second detection element 54. The first detection element 43 and the second detection element 54 are preferably thermocouples.

[0065] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Fig.10 The top or bottom of the insulation component 1 is connected to the heating plate, and an avoidance portion 13 is provided on the insulation component 1. The avoidance portion 13 is matched with the mounting hole to avoid affecting the installation of the heating component when the insulation module is set on the heating plate.

[0066] Specifically, when the heat preservation module is connected to the upper heating module 4, the top of the heat preservation member 1 is connected to the upper heating plate 41, and the avoidance portion 13 can be used to avoid the installation of the first heating member 42, such as Figure 6 and Figure 7 When the heat preservation module is connected to the lower heating module 5, the bottom of the heat preservation component 1 is connected to the lower heating plate 51, and the avoidance portion can be used to avoid the installation of the second heating component 52, as shown. Fig.10 and Fig.11 shown.

[0067] In some embodiments of this application, please refer to Figure 6 , Figure 7 and Fig.11The top or bottom of the thermal insulation component 1 has a first positioning surface 14 and a second positioning surface 15 set at an angle. The first positioning surface 14 is in contact with the end surface of the heating plate, and the second positioning surface 15 is in contact with the bottom surface or top surface of the heating plate 41, which can be used to achieve rapid positioning between the thermal insulation component 1 and the heating plate, thereby facilitating rapid assembly of the thermal insulation module.

[0068] Specifically, when the heat preservation module is connected to the upper heating module 4, the top of the heat preservation component 1 is connected to the upper heating plate 41, the first positioning surface 14 is used to fit with the end surface of the upper heating plate 41, and the second positioning surface 15 is used to fit with the bottom surface of the upper heating plate 41. When the heat preservation module is connected to the lower heating module 5, the bottom of the heat preservation component 1 is connected to the lower heating plate 51, the first positioning surface 14 is used to fit with the end surface of the lower heating plate 51, and the second positioning surface 15 is used to fit with the top surface of the lower heating plate 51.

[0069] Specifically, when the heating plate (i.e., the upper heating plate 41 and the lower heating plate 51) is a rectangular block structure, the angle between the end face and the bottom face of the heating plate is 90°. At this time, the first positioning surface 14 and the second positioning surface 15 are connected to form an L-shaped positioning structure, which can quickly realize the horizontal positioning and vertical positioning of the insulation module.

[0070] In some embodiments of this application, please refer to Figure 4 and Figure 5 The hot pressing molding mechanism also includes a lifting module 6, which is connected to the upper heating module 4 and is used to drive the upper heating module 4 and the heat preservation module to rise and fall as a whole, so as to avoid blocking the mold 7 during the process of moving the mold 7. During molding, the lifting module 6 pressurizes the upper heating module 4 and the mold 7, so that the workpiece in the mold 7 fits with the inner cavity of the mold 7 under the extrusion effect, thereby realizing the preparation of the hot-bent glass workpiece.

[0071] In some embodiments of the present application, the lifting module 6 includes a lifting drive 61, a guide rail 62 and a connecting seat 63, the bottom end of the connecting seat 63 is connected to the upper heating module 4, the top of the connecting seat 63 is connected to the lifting drive 61, and the guide rail 62 can guide the connecting seat 63 in the vertical direction to ensure that when the connecting seat 63 is pressed down, a vertical downward pressure is applied to the mold 7. Specifically, the lifting drive 61 can be a cylinder, a hydraulic cylinder or other components.

[0072] A third aspect of the present application provides a heat bending machine, comprising the heat preservation module in the above embodiment; the heat preservation module can be applied to the preheating station and the forming station in the heat bending machine.

[0073] Alternatively, the heat bending machine includes the hot pressing forming mechanism in the above embodiment, which can be used to perform hot pressing forming processing on the mold 7 inside the heat bending machine. During the processing, the overall temperature of the mold 7 is balanced, which is beneficial to ensuring the forming effect of the hot-bent glass workpiece.

[0074] See also Figures 1 to 11 In some embodiments of the present application, the method of using the above-mentioned hot pressing forming mechanism is as follows:

[0075] Step 1: The heat preservation module is arranged at both ends of the upper heating module 4 and / or the lower heating module 5, and the power cables of the temperature detection element 3 and the heating element 2 are connected to the controller of the hot pressing forming mechanism;

[0076] Step 2: Move the mold 7 onto the lower heating plate 51 of the lower heating module 5, and move the lifting module 6 to make the upper heating module 4 fit the top of the mold 7. At this time, the heat preservation modules are located at both ends of the mold 7.

[0077] Step 3: Confirm the overall temperature distribution of the mold 7 by obtaining temperature information through the temperature detection elements (i.e., the first detection element 43 and the second detection element 51) in the upper heating module 4 and the lower heating module 5 and the temperature detection element 3 in the heat preservation module;

[0078] Step 4: Adjust the power of the first heating element 42, the second heating element 52 and the heating element 2 to make the overall temperature of the mold 7 balanced;

[0079] Step 5: Apply pressure to the upper heating module 4 and the mold 7 through the lifting module 6 to form the workpiece inside the mold 7.
