Description

Technical Field

[0001] This utility model belongs to the field of hot bending technology, specifically relating to a hot bending forming device and hot bending equipment. Background Technology

[0002] With the increasing diversification of demands for consumer electronics products, the various structural components required for product assembly are also showing a trend towards structural diversification. Taking cover plates for consumer electronics products as an example, the required structures for components such as gemstone cover plates and glass cover plates are evolving from basic planar structures to complex styles such as 2.5D curved surface structures and 3D curved surface structures, leading to increasingly higher requirements for hot bending forming equipment. Existing hot bending forming equipment has low cooling efficiency for hot-bent parts. On the one hand, this results in a long hot bending process, affecting production efficiency. On the other hand, if the hot-bent parts cannot be cooled and solidified in time, the subsequent demolding process can easily cause deformation of the hot-bent parts, affecting product quality.

[0046] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0047] The following is a reference appendix. Figures 1 to 7This invention describes a hot bending forming device and a hot bending equipment.

[0048] like Figure 1 As shown, the first aspect of this utility model provides a hot bending and forming device, comprising:

[0049] Mounting base 1;

[0050] The hot pressing mechanism 2 includes a first driving component 21 and a hot pressing component 22. The first driving component 21 is mounted on the mounting base 1, and the first end of the hot pressing component 22 is connected to the driving end of the first driving component 21, and the second end is provided with a hot pressing forming surface. The hot pressing component 22 is also provided with a cooling and bonding surface that is opposite to the hot pressing forming surface.

[0051] The cooling mechanism 3 includes a second drive assembly 31 and a first cooling plate 32. The first cooling plate 32 forms a circulating water channel. The second drive assembly 31 is disposed on the drive end of the first drive assembly 21 and is drivenly connected to the first cooling plate 32 to drive the first cooling plate 32 to move closer to or away from the cooling contact surface.

[0052] Initially, the first cooling plate 32 is positioned away from the cooling bonding surface. During hot pressing, the first drive assembly 21 drives the hot pressing assembly 22 closer to the product, and the cooling mechanism 3 moves synchronously with the hot pressing assembly 22. After hot pressing, the first drive assembly 21 controls the hot pressing assembly 22 to remain stationary, and the hot pressing assembly 22 stops heating. The second drive assembly 31 drives the first cooling plate 32 closer to and onto the cooling bonding surface, cooling the hot pressing assembly 22 and the product to allow the product to solidify. After solidification, the first drive assembly 21 drives the hot pressing assembly 22 to reset, and the second drive assembly 31 drives the first cooling plate 32 to reset. Thus, by incorporating the cooling mechanism 3, the hot bending and pressing device can achieve rapid product solidification, improving production efficiency and quality.

[0053] like Figure 2As shown in this embodiment of the invention, the hot pressing assembly 22 includes a forming plate 221 and a hot pressing mold 222. The side of the hot pressing mold 222 facing away from the forming plate 221 forms a hot pressing surface, and the side of the hot pressing mold 222 facing the forming plate 221 forms a cooling and bonding surface. An adjustment space is formed between the forming plate 221 and the hot pressing mold 222 to allow the first cooling plate 32 to move. The forming plate 221 distributes the downward thrust of the first driving assembly 21 to various positions of the hot pressing mold 222, thereby making the pressure of the hot pressing mold 222 on the product more uniform and avoiding problems such as deformation and defects caused by uneven local force, thus improving the hot pressing quality of the product. The adjustment space formed between the forming plate 221 and the hot pressing mold 222, with the first cooling plate 32 located within it, allows the first cooling plate 32 to directly contact the hot pressing mold 222, thus avoiding the technical problem of reduced cooling efficiency due to the addition of the forming plate 221.

[0054] Specifically, see Figure 3 The hot press mold 222 includes a heating plate 2221, a heat spreader 2222 and an upper mold 2223 stacked from top to bottom.

[0055] like Figure 2 and Figure 3 As shown in this embodiment of the invention, a first connecting post 223 is provided between the forming plate 221 and the hot pressing mold 222. The first connecting post 223 includes an outer ring body 2231 and a bolt body 2232. The two ends of the outer ring body 2231 abut against the forming plate 221 and the hot pressing mold 222, respectively. The bolt body 2232 passes through the forming plate 221, the outer ring body 2231, and the hot pressing mold 222 in sequence, and is threadedly connected to the forming plate 221 and the hot pressing mold 222. The outer ring body 2231 abuts against the forming plate 221 and the hot pressing mold 222, respectively. That is, the height of the outer ring body 2231 determines the height of the adjustment space. In the assembly process of the hot bending forming device, compared with the scheme of connecting the forming plate 221 and the hot pressing mold 222 only by bolts, the consistency of the height of the adjustment space can be guaranteed more accurately and efficiently, and there is no need to measure and adjust the installation position of the forming plate 221 and the hot pressing mold 222.

[0056] Furthermore, recesses are formed on opposite sides of the forming plate 221 and the hot pressing mold 222. These recesses are used to position and set the outer ring body 2231, thereby further improving assembly efficiency.

[0057] Further, see Figure 3 The profiled plate 221 includes an upper plate 2211 and a lower plate 2212 that are detachably connected. The upper plate 2211 is connected to the first drive assembly 21, and the lower plate 2212 forms a threaded hole for the bolt body 2232 to pass through.

[0058] In this embodiment of the invention, there are multiple first connecting posts 223 arranged in an array. This array arrangement makes the connection between the forming plate 221 and the hot pressing mold 222 more stable and the stress distribution more uniform. Because the multiple first connecting posts 223 are evenly distributed, the pressure on each part of the product during the hot pressing process can be transmitted more evenly through these arrayed first connecting posts 223, further reducing the possibility of defects caused by local stress differences in the product.

[0059] like Figure 3 As shown in this embodiment of the invention, the hot pressing mold 222 has a push rod hole extending through it along the height direction. The hot pressing assembly 22 also includes a push rod assembly 224. One end of the push rod assembly 224 is connected to the forming plate 221, and the other end of the push rod assembly 224 extends elastically out of the push rod hole. The push rod assembly 224 can flexibly extend and retract within the push rod hole. After hot pressing is completed, the formed product can be automatically ejected from the hot pressing mold 222 using the push rod assembly 224, eliminating the need for manual removal. This not only improves the efficiency of product removal but also effectively avoids damage to the product that may be caused by manual operation, further ensuring product quality. It also reduces the labor intensity of operators and improves the automation level of the entire hot pressing process.

[0060] Specifically, the push rod assembly 224 includes a push rod body and a spring. A hole for accommodating the spring is formed on the molding plate 221. One end of the push rod body is connected to the spring, and the other end passes through the push rod hole.

[0061] like Figure 2 and Figure 4 As shown in this embodiment of the invention, the second driving component 31 includes a lifting driving member 311 and a water pipe connecting component. The lifting driving member 311 is disposed on the driving end of the first driving component 21. The lifting driving member 311 is drivenly connected to the first cooling plate 32 through the water pipe connecting component. The water pipe connecting component passes through the forming plate 221 and connects to the inlet and outlet of the first cooling plate 32. The water pipe connecting component has two functions: firstly, it acts as an intermediate connection between the lifting driving member 311 and the first cooling plate 32; secondly, it connects the circulating water path of the first cooling plate 32 to the water source. By setting the water pipe as a connecting component, material costs can be reduced, and the structure of the cooling mechanism 3 can be made more compact, making it easier to install on the hot pressing mechanism 2.

[0062] like Figure 4As shown in this embodiment of the invention, the water pipe connection assembly includes a water pipe connection seat 312 and connecting water pipes 313. A lifting drive 311 drives the connecting water pipe connection seat 312. The water pipe connection seat 312 connects to two connecting water pipes 313. One connecting water pipe 313 is configured as an inlet pipe, passing through the forming plate 221 and connecting to the inlet of the first cooling plate 32. The other connecting water pipe 313 is configured as an outlet pipe, passing through the forming plate 221 and connecting to the outlet of the first cooling plate 32. The arrangement of the water pipe connection seat 312 allows the two connecting water pipes 313 to be spaced apart, ensuring that the thrust on the first cooling plate 32 is evenly distributed at both ends, thus better guaranteeing the stability of the first cooling plate 32 during lifting.

[0063] Of course, this utility model is not limited to this. The water pipe 313 can also be directly connected by the lifting drive component 311.

[0064] like Figure 4 As shown in this embodiment of the invention, a vertically extending guide rail 14 is provided on the mounting base 1, and a slider is provided on the guide rail 14. The water pipe connector 312 is connected to the slider. The slider can slide up and down along the guide rail 14, so that the water pipe connector 312 can achieve lifting and lowering actions more smoothly and accurately under the drive of the lifting drive component 311, which improves the stability of the entire second drive component 31, thereby ensuring the reliability of the first cooling plate 32 during the lifting and lowering process, and can also effectively reduce the frictional loss caused by the lifting and lowering of the connecting water pipe 313 relative to the forming plate 221.

[0065] like Figure 2 As shown, in this embodiment of the present invention, the first driving component 21 includes a telescopic driving member 211, an intermediate connecting seat 212 and a connecting rod 213. The telescopic driving member 211 is disposed on the mounting base 1. The top surface of the intermediate connecting seat 212 is connected to the driving end of the telescopic driving member 211. The two ends of the connecting rod 213 are respectively connected to the bottom surface of the intermediate connecting seat 212 and the hot pressing component 22. The second driving component 31 is disposed at the intermediate connecting seat 212.

[0066] Specifically, see Figure 4 The mounting base 1 includes a mounting frame 13, a mounting top plate 12, and a mounting bottom plate 11. There are two mounting frames 13, which are spaced apart. The mounting top plate 12 and the mounting bottom plate 11 are respectively connected to the top and bottom of the two mounting frames 13. The telescopic drive component 211 is provided on the mounting top plate 12. The intermediate connecting seat 212 is sandwiched between the two mounting frames 13. The side of the intermediate connecting seat 212, which is arranged along the interval direction of the two mounting frames 13, is provided with a second drive component 31.

[0067] Furthermore, the mounting frame 13 has two spaced-apart support columns 131, a guide rail 14 is mounted on one of the support columns 131, and a water pipe 313 is located between the two support columns 131.

[0068] like Figure 5 and Figure 7 As shown, to achieve the above objectives, the second aspect of this utility model provides a hot bending equipment, which includes a turntable device 400, a feeding / discharging device 700, a heating device, a cooling device, and the aforementioned hot bending forming device. The feeding / discharging device 700, heating device, hot bending forming device, and cooling device are fixedly arranged above the turntable device 400 along its circumference. The turntable device 400 can sequentially convey the material to be processed to different devices for corresponding processing through circumferential rotation. The feeding / discharging device 700 is responsible for conveying and removing the material; the heating device can accurately heat the material to reach a suitable hot bending temperature; and the cooling device can quickly and effectively cool and shape the hot-bent material, ensuring the quality and shape accuracy of the product. The hot bending equipment utilizes the circumferential motion of the turntable, with each device processing the material sequentially during the continuous rotation of the turntable, greatly reducing processing intervals and effectively improving overall production efficiency. Furthermore, this arrangement ensures that the number of molds corresponds to the number of processing devices above the turntable device 400, reducing the use of molds.

[0069] like Figure 5 and Figure 6 As shown in this embodiment of the invention, the turntable device 400 is provided with multiple lowering devices 500. Each lowering device 500 includes, from top to bottom, a lower mold 501, a second heating plate 502, a second cooling plate 503, and a mounting plate 504. A second connecting column is provided between the mounting plate 504 and the second heating plate 502. The second cooling plate 503 is movably disposed along the second connecting column. The hot bending equipment also includes a lifting device 600 disposed opposite to the hot bending forming device along the height direction. The mounting plate 504 has a lifting hole through which the lifting device 600 passes. Thus, by cooperating with the lowering devices 500 and the hot bending forming device, heating and cooling can be performed on the upper and lower sides of the product respectively, ensuring uniform heating of the product during hot pressing and improving the cooling efficiency after hot pressing.

[0070] In this embodiment of the invention, the hot bending equipment further includes a positioning device. The positioning device has a retractable positioning rod, and a positioning hole is provided on the turntable for the positioning rod to pass through. The positioning device allows the positioning rod to quickly pass into the positioning hole when the turntable rotates to a specific position, accurately determining the position of the turntable. This ensures that each processing device can accurately operate on the material on the turntable, thereby improving the accuracy of the hot bending process and reducing product defects caused by positional deviations.

[0071] Specifically, the positioning device includes a pneumatic-hydraulic linkage cylinder, a positioning rod, and a protective sleeve. The pneumatic-hydraulic linkage cylinder can drive the positioning rod to extend out of the protective sleeve, which can play a protective role and absorb the radial force on the positioning rod.
