Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a bending mechanism with an upward bending function and a hot bending machine. Background Art

[0002] When bending electronic product materials, such as upward bending of sheet materials such as mylar sheets and insulating sheets, the current processing method is generally to place the sheet material on a forming die and press the sheet material onto the forming die to achieve upward bending processing. However, this method has a poor bending effect on the sheet material, and the sheet material is prone to rebound after bending, resulting in the bending angle not meeting the production requirements. Therefore, there is an urgent need for a bending mechanism that can better perform upward bending on sheet materials. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bending mechanism with an upward bending function and a hot bending machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or creation condition.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A bending mechanism with an upward bending function includes: a frame; a material supporting member connected to the frame; a forming unit including a bottom die and a side die, the bottom die is connected to the frame, the side die is arranged on the frame on the side of the bottom die away from the material supporting member, and the height of the side die is greater than that of the bottom die; a first lifting driving member connected to the frame, the first lifting driving member is drivingly connected with a heating plate, the heating plate is located above the bottom die, and the first lifting driving member can drive the heating plate to move up and down.

[0006] This technical solution has at least the following beneficial effects: Move the sheet material to be bent onto the side die, the heating plate is directly opposite to the position where the sheet material needs to be bent, a bending and forming concave angle is formed between the side die and the bottom die, drive the heating plate to move down by the first lifting driving member, heat the position where the sheet material needs to be bent, and with the downward pressure of the heating plate on the sheet material, bending and forming can be carried out at the concave angle position formed by the bottom die and the side die, so that the main body part of the sheet material is located on the bottom die, and the bent position of the sheet material abuts against the side die, completing the upward bending of the sheet material. Bending the sheet material after heating in this way makes the bent position not easy to rebound after forming, effectively improving the quality of bending processing of sheet materials such as mylar sheets and insulating sheets.

[0007] As a further improvement of the above technical solution, the utility model further includes a second lifting driving member, which is connected to the frame. The second lifting driving member is drivingly connected with a pressing block, and the pressing block is located above the sheet supporting member. The second lifting driving member can drive the pressing block to move up and down. Before the heating plate presses down on the sheet for heating, the second lifting driving member drives the pressing block to move down onto the sheet, pressing the sheet tightly against the sheet supporting member first, and then the heating plate heats and bends the sheet. In this way, through the downward pressing and positioning of the sheet, the stability during the heating and bending of the sheet can be improved, the offset of the sheet can be reduced, which is beneficial to further improving the bending processing quality.

[0008] As a further improvement of the above technical solution, the forming unit includes a first translation driving member connected to the frame. The first translation driving member is drivingly connected with a first slider, and the first slider is located on the side of the side mold away from the bottom mold. The top side of the first slider is connected with a bending plate, and the bending plate protrudes from the first slider towards the side mold. The first translation driving member can drive the first slider to approach the side mold and make the bending plate move directly above the bottom mold, or drive the first slider to move away from the side mold and make the bending plate move out of directly above the bottom mold. After the heating plate finishes heating and bending the sheet, the first translation driving member can drive the bending plate to abut against the bending position of the sheet through the first slider to assist in forming the sheet. When the heating plate moves upward, during subsequent processes such as blowing air to cool the sheet, it is not easy to damage the bending position of the sheet. In addition, when the heating plate moves upward, the first translation driving member can also drive the bending plate to further bend the bending position of the sheet inward through the first slider, so as to form a larger angle for the bending of the sheet, improving the processing quality of the sheet and the bending angle of the sheet.

[0009] As a further improvement of the above technical solution, two first limiting frames are connected to the frame, and two first limiting plates are respectively connected to the two first limiting frames. The first limiting plates are located above the bending plate, and a first limiting area is formed between the two first limiting plates. Guide rounded corners are respectively arranged at the side corners of the two first limiting plates facing each other. When the sheet is transferred to the processing position, it can be moved into the position between the two first limiting plates. When moving between the two first limiting plates, the guide rounded corners at one end of the two first limiting plates can be used to guide the entry of the sheet, so that the sheet can be smoothly moved into the first limiting area. By using the two first limiting plates to limit the two sides of the sheet, the accuracy of the sheet when transferred to the processing position can be improved.

[0010] As a further improvement of the above technical solution, the forming unit includes a second translation driving member connected to the frame. The second translation driving member is drivingly connected to a second slider. The second translation driving member can drive the second slider to approach or move away from the sheet supporting member, and the side mold is connected to the second slider. At this time, the side mold has a movable and adjustable structural form on the frame. Before bending the sheet, the second translation driving member drives the side mold to approach or move away from the sheet supporting member through the second slider, which can conveniently adjust the bending position. After the sheet is bent, the side mold can be moved away from the sheet supporting member, which is convenient for further processing of the bent sheet or moving the sheet outwards.

[0011] As a further improvement of the above technical solution, two second limiting frames are connected to the frame. The two second limiting frames are respectively connected with second limiting plates. The second limiting plates are located above the second slider. A second limiting area is formed between the two limiting plates. Limiting protrusions are respectively arranged at the top of one side of the two limiting plates facing each other. When the sheet needs to be transferred to the processing position, the sheet to be bent is moved between the two second limiting plates. The two limiting protrusions can be used to limit the sheet from tilting upwards and disengaging from the second limiting plates when the sheet is moved into the two second limiting plates, ensuring that the sheet can be transferred in place. By using the two second limiting plates to limit the two sides of the sheet, the accuracy of the sheet transferred to the processing position can be improved. When the sheet is bent, the bending position of the sheet can cross the limiting protrusions to complete the bending.

[0012] As a further improvement of the above technical solution, the forming unit further includes a forming die, a forming plate, a third translation driving member and a bending block. The forming die and the third translation driving member are respectively connected to the machine frame. The forming die is located on the side of the sheet supporting member away from the bottom die. The forming plate is connected to the top side of the forming die. The forming plate protrudes from the forming die in a direction away from the sheet supporting member. The third translation driving member is drivingly connected to the bending block. The bending block is located on the side of the forming die away from the sheet supporting member. The third translation driving member can drive the bending block to approach or move away from directly below the forming plate. There are two heating plates. One heating plate is located above the forming plate. The first lifting driving member can drive the two heating plates to move up and down. After the sheet to be bent is placed in place, one side of the sheet is located on the forming plate. During the bending process, one of the heating plates moves down to the position where the sheet on the forming plate needs to be bent. Similarly, the sheet is first heated and bent downward. After pre-forming the bending position of the sheet, the heating plate moves up and resets. The third translation driving member drives the bending block to move below the forming plate to further bend and form the sheet, realizing downward bending of the sheet. On the other side of the sheet supporting member, the other heating plate bends the sheet upward on the side die and the bottom die. In this way, upward and downward bending of the sheet can be achieved, further enriching the overall use functions.

[0013] As a further improvement of the above technical solution, there are two forming units. The two forming units are respectively located on both sides of the sheet supporting member. There are two heating plates correspondingly arranged above the two bottom dies. The first lifting driving member can drive the two heating plates to move up and down. Having two forming units on both sides of the sheet supporting member that can bend the sheet upward can realize upward bending of both sides of the sheet at the same time, further enriching the overall use functions.

[0014] A hot bending machine includes the bending mechanism with the upward bending function as described above.

[0015] The technical solution has at least the following beneficial effects: Since the hot bending machine has a bending mechanism with the upward bending function, when bending a workpiece, the sheet can be heated and then bent, so that the bent position is not easy to rebound after forming, effectively improving the quality of bending and processing sheets such as mylar sheets and insulating sheets.

Specific Embodiments

[0023] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all the connection relationships mentioned in the text do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0024] Refer to Figure 1, A bending mechanism with a bending function, comprising: a frame 100; a sheet supporting member 200 connected to the frame 100; a forming unit including a bottom die 310 and a side die 320, the bottom die 310 being connected to the frame 100, the side die 320 being disposed on the frame 100 on a side of the bottom die 310 away from the sheet supporting member 200, and the height of the side die 320 being greater than the height of the bottom die 310; a first lifting driving member 410 connected to the frame 100, the first lifting driving member 410 being drivingly connected to a heating plate 420, the heating plate 420 being located above the bottom die 310, and the first lifting driving member 410 being capable of driving the heating plate 420 to move up and down.

[0025] As can be seen from the above, the sheet to be bent is moved onto the side die 320, the heating plate 420 is positioned directly opposite the position on the sheet where bending is required, a bending forming concave angle is formed between the side die 320 and the bottom die 310, the first lifting driving member 410 drives the heating plate 420 to move downward to heat the position on the sheet where bending is required, and as the heating plate 420 presses down on the sheet, bending forming can be achieved at the concave angle position formed between the bottom die 310 and the side die 320, such that the main body portion of the sheet is located on the bottom die 310, while the bent position of the sheet abuts against the side die 320, completing the upward bending of the sheet. Thus, by heating and then bending the sheet, the bent position is not easily rebounded after forming, effectively improving the quality of bending processing of sheets such as mylar sheets and insulating sheets.

[0026] In the above embodiment, directly heating and pressing the sheet by the heating plate 420 easily causes the sheet to shift. Therefore, the present utility model further includes a second lifting driving member 510 connected to the frame 100, the second lifting driving member 510 being drivingly connected to a pressing block 520, the pressing block 520 being located above the sheet supporting member 200, and the second lifting driving member 510 being capable of driving the pressing block 520 to move up and down. Before the heating plate 420 presses down and heats the sheet, the second lifting driving member drives the pressing block 520 to move downward onto the sheet to first press the sheet tightly against the sheet supporting member 200, and then the heating plate 420 heats and bends the sheet. Thus, by pressing and positioning the sheet, the stability during heating and bending of the sheet can be improved, the shift of the sheet can be reduced, which is beneficial to further improving the quality of bending processing.

[0027] In the above embodiment, as Embodiment 1 of the forming unit, bending of the sheet is mainly achieved by the heating plate 420. In order to improve the bending effect of the sheet, in Embodiment 2, as Figure 2As shown, the forming unit includes a first translation driving member 331 connected to the frame 100. The first translation driving member 331 is drivingly connected to a first slider 332. The first slider 332 is located on the side of the side mold 320 away from the bottom mold 310. The top side of the first slider 332 is connected to a bending plate 333. The bending plate 333 protrudes from the first slider 332 in the direction close to the side mold 320. The first translation driving member 331 can drive the first slider 332 close to the side mold 320 and move the bending plate 333 directly above the bottom mold 310, or drive the first slider 332 away from the side mold 320 and move the bending plate 333 out of the position directly above the bottom mold 310. After the heating plate 420 heats and bends the sheet material, the first translation driving member 331 can drive the bending plate 333 through the first slider 332 to abut against the bending position of the sheet material to assist in forming the sheet material. When the heating plate 420 moves upward, it is not easy to damage the bending position of the sheet material during subsequent processes such as blowing air to cool the sheet material. In addition, when the heating plate 420 moves upward, the first translation driving member 331 can also drive the bending plate 333 through the first slider 332 to further bend the bending position of the sheet material inward, so as to form a larger angle for the bending of the sheet material, improving the processing quality of the sheet material and the bending angle of the sheet material.

[0028] In the first embodiment, two first limiting frames 334 are connected to the frame 100. The two first limiting frames 334 are respectively connected to a first limiting plate 335. The first limiting plate 335 is located above the bending plate 333. A first limiting area is formed between the two first limiting plates 335. Guide rounded corners are respectively provided at the side corners of the two first limiting plates 335 facing each other. Similarly, in the first embodiment, a first limiting plate 335 can also be provided. At this time, the first limiting plate 335 is directly installed above the side mold 320. When transferring the sheet material to the processing position, it can be moved into the position between the two first limiting plates 335. When moving between the two first limiting plates 335, the guide rounded corners at one end of the two first limiting plates 335 can be used to guide the entry of the sheet material, so that the sheet material can be smoothly moved into the first limiting area. By limiting the two sides of the sheet material with the two first limiting plates 335, the accuracy of the sheet material transferred to the processing position can be improved.

[0029] In the first embodiment, the side mold 320 can be directly locked to the frame 100. For example, the side mold 320 is fixed to the frame 100 by using connecting parts such as screws. When it is necessary to adjust the sheet material according to the processing position, the locking of the side mold 320 by the screws is released, and the position of the side mold 320 is adjusted movably. In this embodiment, the side mold 320 can be directly adjusted movably on the frame 100. Specifically, as the second embodiment, such as Figure 3 And Figure 4As shown in the figure, the forming unit includes a second translation driving member 341 connected to the frame 100. The second translation driving member 341 is drivingly connected to a second slider 342. The second translation driving member 341 can drive the second slider 342 to approach or move away from the sheet supporting member 200. The side mold 320 is connected to the second slider 342. At this time, the side mold 320 has a movable and adjustable structural form on the frame 100. Before bending the sheet, the second translation driving member 341 drives the side mold 320 to approach or move away from the sheet supporting member 200 through the second slider 342, which can conveniently adjust the bending position. After the sheet bending is completed, the side mold 320 can be moved away from the sheet supporting member 200, which is convenient for further processing of the bent sheet or moving the sheet outwards.

[0030] In the second embodiment, two second limiting frames 343 are connected to the frame 100. The two second limiting frames 343 are respectively connected with second limiting plates 344. The second limiting plates 344 are located above the second slider 342. A second limiting area is formed between the two limiting plates. Limiting ridges are respectively arranged at the top of one side of the two second limiting plates 344 facing each other. In practical applications, the limiting ridges do not need to press on the sheet, and there is a gap between the sheet and the limiting ridges. When the sheet needs to be transferred to the processing position, the sheet to be bent is moved between the two second limiting plates 344. The two limiting ridges can be used to prevent the sheet from tilting upwards and disengaging from the second limiting plates 344 when being moved into the two second limiting plates 344, ensuring that the sheet can be transferred in place. By using the two second limiting plates 344 to limit the two sides of the sheet, the accuracy of the sheet transferred to the processing position can be improved. When the sheet is bent, the bending position of the sheet can cross the limiting ridges to complete the bending.

[0031] In the first and second embodiments of the above forming unit, only unilateral upward bending processing of the sheet can be performed. On the basis of these two implementation manners, bending of both sides of the sheet can also be performed, such as Figure 5As shown, as the third embodiment of the forming unit, the bending method is that one side is bent upward and the other side is bent downward. Specifically, the forming unit further includes a forming die 351, a forming plate 352, a third translation driving member 353 and a bending block 354. The forming die 351 and the third translation driving member 353 are respectively connected to the frame 100. The forming die 351 is located on the side of the material supporting member 200 away from the bottom die 310. The forming plate 352 is connected to the top side of the forming die 351. The forming plate 352 protrudes from the forming die 351 in the direction away from the material supporting member 200. The third translation driving member 353 is drivingly connected to the bending block 354. The bending block 354 is located on the side of the forming die 351 away from the material supporting member 200. The third translation driving member 353 can drive the bending block 354 to be close to or away from directly below the forming plate 352. The number of the heating plates 420 is two. One heating plate 420 is located above the forming plate 352. The first lifting driving member 410 can drive the two heating plates 420 to move up and down. After the sheet to be bent is placed in place, one side of the sheet is located on the forming plate 352. During the bending process, one of the heating plates 420 moves down to the position where the sheet on the forming plate 352 needs to be bent. Similarly, the sheet is first heated and bent downward. After the bending position of the sheet is pre-shaped, the heating plate 420 moves up and resets. The third translation driving member drives the bending block 354 to move below the forming plate 352 to further bend and form the sheet, realizing the downward bending of the sheet. On the other side of the material supporting member 200, the other heating plate 420 bends the sheet upward on the side die 320 and the bottom die 310. In this way, the upward and downward bending of the sheet can be realized, further enriching the overall use function.

[0032] Similarly, on the basis of the first and second embodiments of the above-mentioned forming unit, the two sides of the sheet can also be bent respectively. As the fourth embodiment of the forming unit, as Figure 1 and Figure 3 shown, the two sides of the sheet can be bent upward simultaneously. The number of the forming units is two. The two forming units are respectively located on both sides of the material supporting member 200. Two heating plates 420 are arranged corresponding to the upper sides of the two bottom dies 310. The first lifting driving member 410 can drive the two heating plates 420 to move up and down. There are two forming units on both sides of the material supporting member 200 that can bend the sheet upward, which can realize the simultaneous upward bending of the two sides of the sheet, further enriching the overall use function.

[0033] In practical applications, the first lifting drive member 410, the second lifting drive member 510, the first translation drive member 331, the second translation drive member 341, and the third translation drive member 353 are all used to provide a driving force for linear movement. There are various structural forms, such as cylinders, hydraulic cylinders, or electric push rods, etc.

[0034] A hot bending machine includes the bending mechanism with the above-mentioned upper bending function.

[0035] Since the hot bending machine has a bending mechanism with an upper bending function, when bending a workpiece, the sheet material can be heated and then bent, so that the bent position is not easy to rebound after forming, effectively improving the quality of bending processing of sheet materials such as mylar sheets and insulating sheets.

[0036] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
