Description

Technical Field

[0001] This utility model relates to the field of bending processing, and in particular to a heating mechanism and bending device. Background Technology

[0002] Current bending methods typically involve moving the plastic sheet onto a bending die with a concave corner, moving a heating blade close to the sheet to heat it, and then pressing the sheet against the concave corner of the die to achieve bending. However, when the plastic sheet is thick, most of the heat is directly transferred to the bending die, making it difficult to distribute quickly and evenly at the bending point. This uneven heating, affecting the bending and shaping effect, and can even cause the sheet to break when pressed against the concave corner. Therefore, a structure that can heat the plastic sheet more quickly and evenly at the bending point is urgently needed. Summary of the Invention

[0003] The purpose of this utility model is to provide a heating mechanism and a bending device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] A heating mechanism according to a first aspect of the present invention includes: a frame; a heating assembly including a supporting mold and a heating part disposed on the frame, wherein a heating groove is disposed on the top side of the supporting mold, the heating part is located above the supporting mold, and the heating part has a heating blade that can move downward toward or upward away from the heating groove.

[0005] This technical solution has at least the following beneficial effects: When a plastic sheet needs to be bent, the plastic sheet is first fed into the supporting mold, with the position of the plastic sheet to be bent aligned with the heating groove. Then, the heating blade of the heating unit moves downward, pressing down on the position of the plastic sheet corresponding to the heating groove and heating it. At this time, the part of the plastic sheet located on the bottom side of the heating blade will form a partial wrap around the heating blade, allowing the heat from the heating blade to be quickly transferred to the plastic sheet. Furthermore, since the part of the plastic sheet pressed down by the heating blade is suspended in the heating groove, the heat on the bottom side of the plastic sheet will not be directly transferred to the supporting mold and dissipated outward, effectively slowing down the rate of heat diffusion in the plastic part. This achieves rapid and uniform heating of the position of the plastic sheet to be bent, which is also applicable to thicker plastic sheets. Finally, the external bending mechanism bends the plastic sheet. In this way, pressing the plastic sheet down into the heating groove by the heating blade can quickly form a heating mark, thereby improving the subsequent bending and forming effect.

[0006] According to some embodiments of this utility model, the supporting mold includes two supporting members spaced apart from each other on the frame, and the gap between the two supporting members forms the heating groove. Alternatively, the supporting mold may include two separately arranged supporting members, in which case the heating groove is formed by the gap between the two supporting members.

[0007] According to some embodiments of this utility model, at least one of the support members can move and be positioned on the frame in a direction close to or far from another support member. In use, the support members can be moved according to the thickness of the plastic sheet and the molding requirements of the heat mark, thereby adjusting the gap size. For example, one support member can be adjusted, or both support members can be adjusted simultaneously. When the two support members move away from each other, the gap can be increased; when the two support members move closer together, the gap can be decreased.

[0008] According to some embodiments of this utility model, one side wall of the heating groove is higher than the other side wall. This creates a height difference at the opening of the heating groove. When the plastic sheet is pressed down in the heating groove, the height difference at the opening helps the plastic sheet to form a heating mark and then curl upwards at the point where it needs to be folded. This facilitates bending at the curled-up position during subsequent bending, improving bending stability and quality.

[0009] According to some embodiments of this utility model, the heating unit includes a first lifting drive component and a lifting frame. The first lifting drive component is connected to the frame and is tractively connected to the lifting frame. The first lifting drive component can drive the lifting frame to move up and down. The heating blade is connected to the bottom side of the lifting frame. The first lifting drive component provides a driving force for the lifting blade to move up and down, causing the heating blade to move downward and press against the plastic sheet, or causing the heating blade to move upward and move away from the plastic sheet.

[0010] According to some embodiments of this utility model, the bottom side of the lifting frame is provided with multiple heating blades, and the number of supporting molds is also multiple. Each heating blade is positioned opposite a multiple heating groove. With multiple heating blades, when the lifting frame moves downward, it can simultaneously press the plastic sheet into the multiple heating grooves, thereby forming multiple heating marks on the plastic sheet, facilitating subsequent multiple bending of the plastic sheet.

[0011] A bending device according to a second aspect of the present invention includes a first bending mechanism and the aforementioned heating mechanism. The first bending mechanism includes a first translational drive member and a first bending die. The first translational drive member is connected to the frame and is tractively connected to the first bending die. The first translational drive member can drive the first bending die to move above or away from the supporting die.

[0012] This technical solution has at least the following beneficial effects: When the first bending die bends the plastic sheet, it directly bends and forms the plastic sheet on the supporting die. Specifically, after the heating blade presses the plastic sheet against the heating groove to form a heating mark, the first translation drive moves the first bending die above the supporting die to bend the plastic sheet. When the plastic sheet is bent at an angle of no more than 90 degrees, the heating blade does not need to retract. However, when the plastic sheet needs to be bent at an angle greater than 90 degrees, the heating blade moves upward and retracts first, and then the first bending die bends the plastic sheet. In this way, heating and bending are performed directly on the supporting die. Furthermore, since the heating blade presses the plastic sheet down into the heating groove in the heating mechanism, a heating mark can be quickly formed, effectively improving the bending and forming effect.

[0013] According to some embodiments of this utility model, the first bending mechanism further includes a second lifting drive component and a first pressure plate. The second lifting drive component is connected to the frame at a position above the supporting mold. The second lifting drive component is drively connected to the first pressure plate, and can drive the first pressure plate downwards towards or upwards away from the supporting mold. Before bending the plastic sheet, the second lifting drive component first drives the first pressure plate downwards to press and position the plastic sheet on the supporting mold. This improves the stability of the plastic sheet during bending, thereby improving the heating and bending forming effect.

[0014] A bending device according to a third aspect of the present invention includes a second bending mechanism, a first conveying mechanism, a first pressing mechanism, and the aforementioned heating mechanism. The second bending mechanism, the first conveying mechanism, and the first pressing mechanism are respectively disposed on the frame. The first pressing mechanism has a second pressure plate that can move up and down. The first conveying mechanism has a first conveying member that can move back and forth below the supporting mold and the second pressure plate. The second bending mechanism has a second bending mold that can be moved horizontally toward or away from the second pressure plate.

[0015] This technical solution has at least the following beneficial effects: After the plastic sheet is heated to form a heating mark, it is moved outward from the supporting mold and then bent. Specifically, after the heating mechanism heats the plastic sheet to form a heating mark, the first conveying component in the first conveying mechanism moves the plastic sheet to below the second pressure plate. Then, the second pressure plate in the first pressing mechanism moves downward to press and position the plastic sheet on the frame. Next, the second bending mold in the second bending mechanism moves closer to the plastic sheet and further bends the plastic sheet at the position where the heating mark is formed. In this way, the heated plastic part is moved out of the supporting mold and then bent. Furthermore, since the heating mechanism can quickly form a heating mark by pressing the plastic sheet into the heating groove through the heating blade, the bending and forming effect is effectively improved.

[0016] A bending device according to a fourth aspect embodiment of the present invention includes a shaping mold, a second transfer mechanism, a third bending mechanism, a fourth bending mechanism, a fifth bending mechanism, and the aforementioned heating mechanism. Multiple heating blades are provided. The shaping mold is connected to a frame and has a first shaping portion and a second shaping portion spaced apart. A gap is formed between the first shaping portion and the second shaping portion and the frame. The second transfer mechanism has a second transfer member that can move back and forth between the supporting mold and the gap. The third bending mechanism and the fourth bending mechanism... The third bending mechanism is disposed on the frame, and the fourth bending mechanism is disposed on the frame. The third bending mechanism has a third bending die that can move up and down. The third bending die can move up to the side of the second shaping part away from the first shaping part or move down below the gap. The fourth bending mechanism has a fourth bending die that can be moved horizontally above the second shaping part or away from the second shaping part. The fifth bending mechanism has a fifth bending die that can move up and down. The fifth bending die can move down to the side of the first shaping part close to the second shaping part or move up away from the first shaping part.

[0017] This technical solution has at least the following beneficial effects: Because multiple heating blades are installed within the heating mechanism, when these blades move downwards and press against the plastic sheet, multiple heating marks can be formed on the plastic sheet. Then, the second transfer member in the second transfer mechanism moves the plastic sheet to the gap below the first and second shaping parts. The first and second shaping parts can limit the upward movement of the plastic sheet. At this time, the third bending die in the third bending mechanism moves upwards, bending the plastic sheet upwards around the side of the second shaping part away from the first shaping part. Then, the fourth... The fourth bending die in the bending mechanism moves horizontally above the second shaping part, bending the plastic sheet upwards to bend the portion above the second shaping part towards the first shaping part. Then, the fifth bending die in the fifth bending mechanism moves downwards, pressing the plastic sheet downwards at the position between the first and second shaping parts, causing the plastic sheet to bend upwards around the position where it abuts the first shaping part. This achieves multiple bending after the plastic sheet is removed from the supporting die. Furthermore, since the heating mechanism uses a heating blade to press the plastic sheet into the heating groove, heating marks can be quickly formed, effectively improving the bending and forming effect.

Detailed Implementation

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0024] Reference Figure 1 According to a first aspect of the present invention, a heating mechanism includes: a frame 100; and a heating assembly including a support mold 210 disposed on the frame 100 and a heating part. The support mold 210 has a heating groove 211 disposed on its top side, and the heating part is located above the support mold 210. The heating part has a heating blade 220 that can move downward toward or upward away from the heating groove 211. Naturally, the heating blade 220 can also be in the form of a heating rod or heating strip to heat the plastic sheet. Its specific shape does not need to be specifically limited, as long as it can press the plastic sheet down at the position of the heating groove 211.

[0025] As described above, when a plastic sheet needs to be bent, it is first fed into the supporting mold 210, with the position to be bent aligned with the heating groove 211. Then, the heating blade 220 of the heating unit moves downward, pressing down on the position of the plastic sheet corresponding to the heating groove 211 and heating it. At this time, the part of the plastic sheet located on the bottom side of the heating blade 220 will partially wrap around the heating blade 220, allowing the heat from the heating blade 220 to be quickly transferred to the plastic sheet. Since the part of the plastic sheet pressed down by the heating blade 220 is suspended in the heating groove 211, the heat on the bottom side of the plastic sheet will not be directly transferred to the supporting mold 210 and dissipated outward, effectively slowing down the heat diffusion rate of the plastic part. This achieves rapid and uniform heating of the position to be bent, which is also applicable to thicker plastic sheets. Finally, the external bending mechanism bends the plastic sheet. In this way, the heating blade 220 presses the plastic sheet down into the heating groove 211, which can quickly form a heating mark, thereby improving the subsequent bending and forming effect.

[0026] In the above embodiments, the supporting mold 210 can be a one-piece structure, in which case the supporting mold 210 can directly form the heating groove 211 during production, or the heating groove 211 can be machined. However, in this embodiment, the supporting mold 210 can be a split structure. Specifically, the supporting mold 210 includes two supporting members spaced apart from the frame 100, and the gap between the two supporting members forms the heating groove 211. Alternatively, the supporting mold 210 can include two split supporting members, in which case the heating groove 211 is formed using the gap between the two supporting members.

[0027] In the above embodiment, the width of the heating groove 211 can be fixed. However, to improve production flexibility, in this embodiment, at least one of the support members can move and be positioned on the frame 100 in a direction close to or away from the other support member. In practical applications, the support members can be fixed to the frame 100 by bolts, positioning pins, snaps, etc. During use, the support members can be moved according to the thickness of the plastic sheet and the forming requirements of the heating mark, thereby adjusting the size of the gap. For example, one support member can be adjusted, or both support members can be adjusted simultaneously. When the two support members move away from each other, the gap can be increased; when the two support members move closer to each other, the gap can be decreased.

[0028] In the above embodiment, the two side walls of the heating groove 211 can be of the same height, and the two sides of the groove opening of the heating groove 211 are flush with each other. However, in order to make the plastic part curl upward at the position where it needs to be folded after the heating mark is formed, thereby facilitating the subsequent bending work, in this embodiment, one side wall of the heating groove 211 is higher than the other side wall. This creates a height difference at the groove opening of the heating groove 211. When the plastic sheet is pressed down at the position of the heating groove 211, the height difference at the groove opening helps the plastic sheet to curl upward at the position where it needs to be folded after the heating mark is formed, which facilitates bending at the curled position during subsequent bending, improving bending stability and quality.

[0029] In addition, in the embodiment where the heating groove 211 forms a vertical height difference, the support member can be moved to form this structure. Specifically, before use, the two sides of the groove opening of the heating groove 211 formed by the two support members can be flush. During the downward pressing of the heating blade 220, one of the support members moves up or down, thereby forming a vertical height difference on both sides of the groove opening of the heating groove 211. There are various ways to move the support member up or down. For example, it can be driven directly by a drive source such as a cylinder, electric screw, or hydraulic cylinder, or it can be driven by a rocker mechanism. In addition, an elastic element such as a spring can be provided on the bottom side of the support member, and the support member can be moved downward by the downward pressure of the heating blade 220.

[0030] In this embodiment, the heating unit includes a first lifting drive 230 and a lifting frame 240. The first lifting drive 230 is connected to the frame 100 and is drively connected to the lifting frame 240. The first lifting drive 230 can drive the lifting frame 240 to move up and down. The heating blade 220 is connected to the bottom side of the lifting frame 240. The first lifting drive 230 can be driven by a cylinder, electric screw, or hydraulic cylinder, while the lifting frame 240 can cooperate with the frame 100 through a sliding structure such as a guide post or slider, thereby improving the stability of the up and down movement of the heating blade 220. The first lifting drive 230 provides a driving force for the up and down movement of the lifting blade, causing the heating blade 220 to move downward and press against the plastic sheet, or to move upward and move away from the plastic sheet.

[0031] The lifting frame 240 may have only one heating blade 220 on its bottom side, but in this embodiment, the lifting frame 240 has multiple heating blades 220 on its bottom side, and there are multiple supporting molds 210. Each heating blade 220 is positioned opposite a multiple heating groove 211. The heating blades 220 can be arranged in a straight line, or adjacent heating blades 220 can be arranged perpendicularly to each other. There are various arrangement options, which can be tailored to the desired bending position of the plastic part. With multiple heating blades 220, when the lifting frame 240 moves downward, it can simultaneously press the plastic sheet into the multiple heating grooves 211, thus forming multiple heating marks on the plastic sheet, facilitating subsequent multiple bending of the plastic sheet.

[0032] A bending device according to a second aspect embodiment of the present invention, such as Figure 2 As shown, the device includes a first bending mechanism and the aforementioned heating mechanism. The first bending mechanism includes a first translation drive 310 and a first bending die 320. The first translation drive 310 is connected to the frame 100 and is drively connected to the first bending die 320. The first translation drive 310 can drive the first bending die 320 to move above or away from the supporting die 210. The first translation drive 310 can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc.

[0033] At this time, when the first bending die 320 bends the plastic sheet, it directly bends and forms the plastic sheet on the supporting die 210. Specifically, after the heating blade 220 presses the plastic sheet against the heating groove 211 to form a heating mark, the first translation drive 310 drives the first bending die 320 to move above the supporting die 210 to bend the plastic sheet. When the plastic sheet is bent at no more than 90 degrees, the heating blade 220 can remain in place. However, when the plastic sheet needs to be bent at more than 90 degrees, the heating blade 220 moves upward and retracts first, and then the first bending die 320 bends the plastic sheet. In this way, the plastic sheet is directly heated and bent on the supporting die 210. Furthermore, since the heating blade 220 presses the plastic sheet down into the heating groove 211 in the heating mechanism, a heating mark can be quickly formed, which effectively improves the bending and forming effect.

[0034] According to some embodiments of this utility model, the first bending mechanism further includes a second lifting drive component 330 and a first pressure plate 340. The second lifting drive component 330 is connected to the frame 100 at a position above the supporting mold 210. The second lifting drive component 330 is drively connected to the first pressure plate 340. The second lifting drive component 330 can drive the first pressure plate 340 downward toward or upward away from the supporting mold 210. The second lifting drive component 330 can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. Before bending the plastic sheet, the second lifting drive component 330 first drives the first pressure plate 340 downward to press and position the plastic sheet on the supporting mold 210. This can improve the stability of the plastic sheet during bending, thereby improving the heating and bending forming effect.

[0035] A bending device according to a third aspect of the present invention includes a second bending mechanism, a first conveying mechanism, a first pressing mechanism, and the aforementioned heating mechanism. The second bending mechanism, the first conveying mechanism, and the first pressing mechanism are respectively disposed on the frame 100. The first pressing mechanism has a second pressure plate that can move up and down. The first conveying mechanism has a first conveying member that can move back and forth between the supporting mold 210 and the second pressure plate. The second bending mechanism has a second bending mold that can be moved horizontally toward or away from the second pressure plate.

[0036] At this point, after the plastic sheet is heated to form a heating mark, it is moved outward from the supporting mold 210 and bent. Specifically, after the heating mechanism heats the plastic sheet to form a heating mark, the first transfer component in the first transfer mechanism moves the plastic sheet to below the second pressure plate. Then, the second pressure plate in the first pressing mechanism moves downward to press and position the plastic sheet on the frame 100. Next, the second bending mold in the second bending mechanism moves closer to the plastic sheet and further bends the plastic sheet at the position where the heating mark is formed. In this way, the heated plastic part is moved out of the supporting mold 210 and then bent. Since the heating knife 220 in the heating mechanism presses the plastic sheet into the heating groove 211, the heating mark can be formed quickly, which effectively improves the bending and forming effect.

[0037] Naturally, the first pressing mechanism has a drive structure that can move the second pressure plate up and down. For example, a third lifting drive is provided on the frame 100. The third lifting drive can be driven by a cylinder, electric screw, or hydraulic cylinder. The third lifting drive is connected to the second pressure plate, and the second pressure plate moves up and down by the third lifting drive. Similarly, the first transfer mechanism includes a second translation drive installed on the frame 100. The second translation drive is connected to the first transfer component. The second translation drive can drive the first transfer component to move back and forth between the supporting mold 210 and the second pressure plate. The second translation drive can be driven by a cylinder, electric screw, or hydraulic cylinder, while the first transfer component can be a suction cup, telescopic rod, or other structural component, mainly used to realize the transfer of plastic parts between the two workstations.

[0038] A bending device according to a fourth aspect embodiment of the present invention, such as Figure 3 As shown, the system includes a shaping mold 410, a second transfer mechanism 420, a third bending mechanism, a fourth bending mechanism, a fifth bending mechanism, and the aforementioned heating mechanism. Multiple heating blades 220 are provided. The shaping mold 410 is connected to the frame 100. The shaping mold 410 has a first shaping portion 411 and a second shaping portion 412 spaced apart. A gap is formed between the first shaping portion 411 and the second shaping portion 412 and the frame 100. The second transfer mechanism 420 has a second transfer member that can move back and forth between the supporting mold 210 and the gap. The third bending mechanism, the fourth bending mechanism, and the fifth bending mechanism are separate... The third bending mechanism is separately installed on the frame 100. It has a third bending die 430 that can move up and down. The third bending die 430 can move up to the side of the second shaping part 412 away from the first shaping part 411 or move down below the gap. The fourth bending mechanism has a fourth bending die 440 that can be moved horizontally above or away from the second shaping part 412. The fifth bending mechanism has a fifth bending die 450 that can move up and down. The fifth bending die 450 can move down to the side of the first shaping part 411 near the second shaping part 412 or move up away from the first shaping part 411.

[0039] Because multiple heating blades 220 are provided in the heating mechanism, when the multiple heating blades 220 move down and press against the plastic sheet, multiple heating marks can be formed on the plastic sheet. Then, the second transfer member in the second transfer mechanism 420 moves the plastic sheet to the gap below the first shaping part 411 and the second shaping part 412. The first shaping part 411 and the second shaping part 412 can limit the upward movement of the plastic sheet. At this time, the third bending die 430 in the third bending mechanism moves upward first, bending the plastic sheet upward around the side of the second shaping part 412 away from the first shaping part 411. Then, the fourth bending die in the fourth bending mechanism... The mold 440 is moved to the top of the second shaping part 412, and the plastic sheet is bent upwards to the part above the second shaping part 412 towards the first shaping part 411. Then, the fifth bending mold 450 in the fifth bending mechanism moves down and presses the plastic sheet down at the position between the first shaping part 411 and the second shaping part 412, so that the plastic sheet is bent upwards around the position where the first shaping part 411 is pressed. This achieves multiple bending after the plastic sheet is removed from the supporting mold 210. In addition, the heating mechanism can quickly form heating marks by pressing the plastic sheet down into the heating groove 211 through the heating blade 220, which effectively improves the bending and forming effect.

[0040] Naturally, the second transfer mechanism 420 has a drive source that can drive the second transfer component to move back and forth. Specifically, the second transfer mechanism 420 includes a third translation drive component mounted on the frame 100. The third translation drive component drives and connects to the second transfer component, and can drive the second transfer component to move back and forth between the supporting mold 210 and the gap. The third translation drive component can be a cylinder, electric screw, or hydraulic cylinder, etc., as the drive source, while the second transfer component can be a suction cup, telescopic rod, or other structural component, mainly used to realize the transfer of plastic parts between two workstations. The third bending mechanism includes a linear drive component mounted on the frame 100. The linear drive component can be a cylinder, electric screw, or hydraulic cylinder, etc., as the drive source, and drives and connects to the third bending mold 430, causing the third bending mold 430 to move back and forth. Similarly, the fourth and fifth bending mechanisms can each use the same drive structure as the third bending mechanism.

[0041] The first bending die 320, the second bending die, the third bending die 430', the fourth bending die 440, and the fifth bending die 450 mentioned above can be connected to the frame 100 through sliding structures such as guide pillars or sliders, thereby further improving the stability of the movement of the first bending die 320, the second bending die, and the third bending die 430.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
