Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a hot bending machine. Background Art

[0002] When bending sheets such as mylar sheets and insulating sheets at present, it is necessary to first separate the stacked sheets, and then put them into a mold for pressing and bending. After completion, the bent sheets are taken out manually or by a machine. In this process, since there is oil or static electricity between the stacked mylar sheets, insulating sheets and other sheets, they will adsorb each other and are difficult to separate, and the sheets are easy to rebound after being bent under pressure, and the bending effect is poor. Therefore, there is an urgent need for a hot bending machine with more stable operation and better bending effect. Summary of the Utility Model

[0003] The purpose of the utility model is to provide 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 hot bending machine, comprising: a frame; a feeding mechanism, including a feeding plate, a backing plate and a transfer component arranged on the frame, the backing plate is located on one side of the feeding plate, a separation baffle extending upward above the feeding plate is connected to the top side of the backing plate, and the transfer component has a transfer end that can move downward close to the feeding plate or upward away from the feeding plate; a forming mechanism, including a supporting member, a heating component and a forming die arranged on the frame, the forming die is located beside the supporting member, and the heating component has a heating plate that can move downward close to the forming die or upward away from the forming die; a transfer mechanism arranged on the frame, and the transfer mechanism is used to transfer the sheet taken out by the transfer end to the supporting member; a discharging mechanism, including a discharging plate and a transfer component arranged on the frame, and the transfer component is used to transfer the sheet on the supporting member to the discharging plate.

[0006] The technical solution has at least the following beneficial effects: Place the stacked sheets on the loading plate. When it is necessary to separate the sheets, the transfer end in the transfer assembly moves downward close to the loading plate, and moves the sheet at the topmost side upward. During the upward movement of the sheet, the side of the sheet will pass by the separation baffle. Under the interference of the separation baffle on the sheet, the side of the sheet will elastically deform downward. At this time, for two sheets adsorbed to each other, the sheet at the topmost side can continue to move upward under the action of the transfer end, while the sheet at the second topmost side cannot continue to move upward due to the obstruction of the separation baffle. In this way, two mutually adsorbed sheets can be effectively separated. After the transfer end separates the sheets, the transfer mechanism transfers the sheets to the material supporting member, the heating plate moves downward to the material supporting member, presses and heats the sheet, and as the heating plate gradually presses down, the sheet can be bent. After completion, the heating plate moves upward to reset. The sheet bent after being heated by the heating plate is not easy to rebound, effectively improving the bending effect on the heating plate. The transfer assembly transfers the sheet on the material supporting member to the unloading plate, and unloads the bent sheet. In this way, the sheets can be stably separated and loaded. It is also applicable to sheets with oil and electrostatic adsorption. And by heating and bending the sheet, the bent position is not easy to rebound after forming, effectively improving the quality of bending processing of sheets such as mylar sheets and insulating sheets.

[0007] As a further improvement of the above technical solution, an air blowing pipe is further arranged on the frame. The air blowing pipe is located beside the separation baffle. One end of the air blowing pipe is connected to an air source, and the other end of the air blowing pipe is arranged towards the upper part of the loading plate. When the mutually adsorbed sheets pass upward through the separation baffle, a gap will be formed between them. At this time, the air source blows air to the side of the sheet through the air blowing pipe, and the air flow passes through the two sheets from the gap, which can further separate the two sheets from each other, further improving the effect of separating the two sheets.

[0008] As a further improvement of the above technical solution, a pressing and lifting driving member is connected to the frame. The pressing and lifting driving member is drivingly connected to a pressing rod. The pressing rod is located above the loading plate. The pressing and lifting driving member can drive the pressing rod to move downward close to the loading plate or move upward away from the loading plate. Before separating the sheets, the pressing and lifting driving member drives the pressing rod to move downward to a position away from the separation baffle of the sheet at the topmost side. At this time, the stacked sheets can be limited up and down. When separating the sheets, the transfer end pulls up one end position of the sheet at the topmost side and crosses over the separation baffle, and then the pressing and lifting driving member drives the pressing rod to move upward, so that the transfer end can separate and move the sheet at the topmost side upward as a whole. In this way, using the pressing rod to maintain the limit when the sheet uses the separation baffle is beneficial to avoiding the problem that the sheet at the second topmost side moves out of the stacked sheets when dropping, and keeping the sheet stack neat.

[0009] As a further improvement of the above technical solution, the forming mechanism further includes a first lifting driving member connected to the frame. The first lifting driving member is drivingly connected with a pressing block, and the first lifting driving member can drive the pressing block to move downward close to or upward away from the material supporting member. Before the heating plate presses down on the sheet for heating, the first lifting driving member drives the pressing block to move downward onto the sheet, pressing the sheet tightly onto the material supporting member first, and then the heating plate heats and bends the sheet. In this way, through the downward 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.

[0010] As a further improvement of the above technical solution, the forming die includes a bottom die and a side die. The bottom die is connected to the frame, and the side die is arranged on the frame on the side of the bottom die away from the material supporting member. The height of the side die is greater than that of the bottom die, and the heating plate can move downward close to or upward away from the side die. When the sheet needs to be bent, the pressing block moves downward close to the sheet and presses the sheet tightly onto the material supporting member. A bending forming concave angle is formed between the side die and the bottom die. The heating plate moves downward to heat the position of the sheet that needs to be bent, and as the heating plate presses down on the sheet, it can be bent and formed at the concave angle position formed by the bottom die and the side die, so that the main part of the sheet is located on the bottom die, and the bent position of the sheet abuts against the side die, completing the upward bending of the sheet.

[0011] As a further improvement of the above technical solution, the forming die includes a first translation driving member connected to the frame. The first translation driving member is drivingly connected with a first slider. The first slider is located on the side of the side die away from the bottom die. The top side of the first slider is connected with a bending plate, and the bending plate protrudes from the first slider in the direction close to the side die. The first translation driving member can drive the first slider to approach the side die and make the bending plate move directly above the bottom die, or drive the first slider to move away from the side die and make the bending plate move out of the position directly above the bottom die. After the heating plate finishes heating and bending the sheet, the first translation driving member can drive the bending plate to abut against the bent 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 bent 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 bent position of the sheet inward through the first slider, which can bend a larger angle for the sheet, improving the processing quality of the sheet and the bending angle of the sheet.

[0012] As a further improvement of the above technical solution, the forming die includes a lower bending fixed die and a lower bending movable die. The lower bending fixed die is connected to the machine frame. A bending protrusion extending in a direction away from the sheet supporting member is provided on the top side of the lower bending fixed die. The lower bending movable die can be moved closer to or away from directly below the bending protrusion on the machine frame. The heating plate can move downward closer to or upward away from the lower bending fixed die. When the sheet needs to be bent, the pressing block moves downward closer to the sheet and presses the sheet against the sheet supporting member. The heating plate in the heating assembly moves downward closer to the sheet to heat the sheet. Then, the heating plate continues to press downward to bend the sheet along the lower bending fixed die. After that, the heating plate moves upward to reset. The lower bending movable die moves on the machine frame in a direction closer to the bending protrusion to continue bending the bending position of the sheet. According to different bending requirements, the lower bending movable die can be moved to different positions to meet the bending requirements of different angles of the sheet. For example, when the lower bending movable die is moved to a position on the side of the bending protrusion, a bending within 90 degrees of the sheet can be achieved. When the lower bending movable die is moved to directly below the bending protrusion, a bending within the angle range of 90 degrees to 180 degrees of the sheet can be achieved. After completion, the lower bending movable die moves away from the bending protrusion to prepare for bending the next workpiece. By heating and then bending the sheet in this way, the bending position is not easily rebounded after forming, effectively improving the quality of bending processing of sheets such as mylar sheets and insulating sheets. And it is not necessary to design different dies according to different bending angles, reducing production costs and improving production efficiency.

[0013] As a further improvement of the above technical solution, the transfer mechanism includes a belt conveyor, a second lifting drive member and a second translation drive member. The belt conveyor is connected to the machine frame at a position between the loading plate and the sheet supporting member. The belt conveyor has a conveying surface moving from the loading plate towards the sheet supporting member. A conveying gap is provided on the conveying surface. The second translation drive member is connected to the machine frame. The second lifting drive member is arranged on the second translation drive member. The second translation drive member can drive the second lifting drive member to move back and forth between the conveying surface and the sheet supporting member. The second lifting drive member is drivingly connected with a dial rod. The second lifting drive member can drive the dial rod to move downward into or upward out of the conveying gap. The transfer end places the separated sheet on the conveying surface, and the conveying surface conveys the sheet towards the sheet supporting member. When the sheet moves to the end of its conveying on the conveying surface, the second lifting drive member drives the dial rod to move downward into the conveying gap, and the second translation drive member drives the dial rod to move towards the sheet supporting member to dial the sheet onto the sheet supporting member, realizing the feeding of the sheet onto the sheet supporting member. After completion, the second lifting drive drives the dial rod to move upward out of the conveying gap, and the second translation drive member drives the dial rod to return to its original position to prepare for the next dialing of the sheet.

[0014] As a further improvement of the above technical solution, the transfer assembly includes a third translation driving member and a third lifting driving member. The third translation driving member is connected to the third lifting driving member. The third translation driving member can drive the third lifting driving member to move back and forth between the sheet supporting member and the blanking plate. The third lifting driving member is drivingly connected with a blanking suction cup. The third lifting driving member can drive the blanking suction cup to move downward close to or upward away from the sheet supporting member. The third translation driving member and the third lifting driving member can respectively provide the driving force for the blanking suction cup to move reciprocally in translation and move up and down. After the bending of the sheet is completed, the blanking suction cup moves downward to the sheet supporting member and moves the sheet upward, and then transfers it above the blanking plate. After releasing the adsorption force of the blanking suction cup on the sheet, the sheet falls onto the blanking plate, completing the blanking of the bent sheet.

[0015] As a further improvement of the above technical solution, the blanking mechanism includes a fourth lifting driving member, a fourth translation driving member and anti-falling side plates. The fourth lifting driving member is connected between the blanking plate and the machine frame. The fourth lifting driving member can drive the blanking plate to move up and down. The anti-falling side plates are respectively connected to both sides of the blanking plate on the machine frame. An avoidance groove is provided at a position between the two anti-falling side plates on the top side of the blanking plate. The fourth translation driving member is connected to the machine frame. The fourth translation driving member is drivingly connected with a push plate. A push block that can enter the avoidance groove is provided on the bottom side of the push plate. The fourth translation driving member can drive the push plate to enter or exit between the two anti-falling side plates. The two anti-falling side plates are located on both sides of the blanking plate. The sheet is placed on the blanking plate. The two anti-falling side plates can prevent the sheet from tipping to both sides, so that the sheets placed on the blanking plate can be gradually stacked upward. When stacked to a certain height, the fourth lifting driving member drives the blanking plate to move downward, and then the fourth translation driving member drives the push plate to enter between the two anti-falling side plates, and the push block on the bottom side of the push plate enters the avoidance groove. As the push plate moves between the two anti-falling side plates, the stacked sheets can be pushed outwards. The push block on the bottom side of the push plate moves in the avoidance groove, and the sheet at the bottommost side of the blanking plate can also be pushed outwards. In this way, it is convenient to collect the sheets that have completed the bending process and improve the overall processing efficiency. Description of the Drawings

Detailed implementation manners

[0024] 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 the 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 scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not simply refer 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 mutual contradiction or conflict.

[0025] Refer toFigure 1 , a hot bending machine, comprising: a frame 100; a feeding mechanism, including a feeding plate 210, a backing plate 240 and a transfer assembly disposed on the frame 100, the backing plate 240 being located on one side of the feeding plate 210, a separating baffle 241 extending upward above the feeding plate 210 being connected to the top side of the backing plate 240, the transfer assembly having a transfer end that can move downward close to the feeding plate 210 or upward away from the feeding plate 210; a forming mechanism, including a material supporting member 310, a heating assembly and a forming die disposed on the frame 100, the forming die being located beside the material supporting member 310, the heating assembly having a heating plate 361 that can move downward close to the forming die or upward away from the forming die, in practical applications, a forming lifting driving member 362 is connected to the frame 100, the forming lifting driving member 362 is drivingly connected to the heating plate 361, and the heating plate 361 is driven by the forming lifting driving member 362 to move up and down; a transfer mechanism, disposed on the frame 100, the transfer mechanism being used for transferring the sheet taken out by the transfer end to the material supporting member 310; a blanking mechanism, including a blanking plate and a transfer assembly disposed on the frame 100, the transfer assembly being used for transferring the sheet on the material supporting member 310 to the blanking plate.

[0026] As can be seen from the above, the stacked sheets are placed on the feeding plate 210. When it is necessary to separate the sheets, the transfer end in the transfer assembly moves downward close to the feeding plate 210, and the topmost sheet is moved upward. During the upward movement of the sheet, the side edge of the sheet will pass through the separating baffle 241. Under the interference of the separating baffle 241 on the sheet, the side edge of the sheet will elastically deform downward. At this time, for two mutually adsorbed sheets, the topmost sheet can continue to move upward under the action of the transfer end, while the second topmost sheet cannot continue to move upward due to the obstruction of the separating baffle 241. In this way, the two mutually adsorbed sheets can be effectively separated. After the transfer end separates the sheets, the transfer mechanism transfers the sheets to the material supporting member 310. The heating plate 361 moves down to the material supporting member 310 to press and heat the sheets. And as the heating plate 361 gradually presses down, the sheets can be bent. After completion, the heating plate 361 moves up and resets. The sheets bent after being heated by the heating plate 361 are not easy to rebound, effectively improving the bending effect on the heating plate 361. The transfer assembly transfers the sheets on the material supporting member 310 to the blanking plate to blank the bent sheets. In this way, the sheets can be stably separated and fed. It is also applicable to sheets with oil and electrostatic adsorption. And by heating and bending the sheets, the bent position is not easy to rebound after forming, effectively improving the quality of bending processing of sheets such as mylar sheets and insulating sheets.

[0027] In order to better separate the two adsorbed sheets from each other, such as Figure 2As shown, in this embodiment, the frame 100 is further provided with a blowing pipe 250, which is located beside the separation baffle 241, one end of the blowing pipe 250 is connected to an air source, and the other end of the blowing pipe 250 is arranged toward the top of the loading plate 210. When the mutually adsorbed sheets pass upward through the separation baffle 241, a gap is formed between the two. At this time, the air source blows air toward the sides of the sheets through the blowing pipe 250, and the air flow passes through the two sheets from the gap, which can further separate the two sheets from each other, further improving the effect of separating the two sheets from each other. In practical applications, thicker sheets can be separated without blowing, while thinner sheets can be further separated from each other by blowing.

[0028] The air blowing pipe 250 can blow air horizontally to the top of the loading plate 210. In order to use the airflow to assist the sheet to be positioned on the stacked sheets, in this embodiment, the end of the air blowing pipe 250 away from the air source is disposed obliquely downward toward the top of the loading plate 210. When the air blowing pipe 250 blows air, an airflow blowing obliquely downward can be formed. When the airflow passes through the two sheets from the gap, the sheet located on the second top side can be further blown downward, thereby further improving the effect of separating the two sheets from each other.

[0029] In order to better keep the sheets neatly arranged on the loading plate 210, in the present embodiment, the frame 100 is connected with a material pressing and lifting driving member, and the material pressing and lifting driving member is drivingly connected with a pressure rod 260, and the pressure rod 260 is located above the loading plate 210. The material pressing and lifting driving member can drive the pressure rod 260 downward toward the loading plate 210 or upward away from the loading plate 210. Before separating the sheets, the pressure material lifting and lowering driving member drives the pressure rod 260 to move downward to a position where the topmost sheet is away from the separation baffle 241. At this time, the stacked sheets can be limited up and down. When separating the sheets, the transfer end pulls up one end position of the topmost sheet and passes over the separation baffle 241. Then the pressure material lifting and lowering driving member drives the pressure rod 260 to move upward again, so that the transfer end can separate and move the entire topmost sheet upward. In this way, the pressure rod 260 is used to keep the limit when the sheet passes through the separation baffle 241, which is conducive to avoiding the problem of the sheet on the second top side moving out of the stacked sheets when it falls, and keeping the sheets stacked neatly.

[0030] The loading plate 210 can be placed horizontally. In order to stack the sheets better on one side of the backing plate 240, in this embodiment, the loading plate 210 extends obliquely downward in the direction close to the backing plate 240. The inclined loading plate 210 can facilitate abutting the stacked sheets against the backing plate 240, which is beneficial to stack the sheets more neatly. In addition, limit plates 230 can be arranged on both sides of the loading plate 210 on the frame 100, so as to stack the sheets more neatly on the loading plate 210.

[0031] When a sheet is removed, the height of the entire stacked sheets on the loading plate 210 will decrease. At this time, the transfer end can be controlled to move further downward to ensure the adsorption of the topmost sheet. In this embodiment, the stacked sheets are raised. Specifically, an electric lead screw 220 is arranged between the frame 100 and the loading plate 210. The electric lead screw 220 is drivingly connected to the loading plate 210, and the electric lead screw 220 can drive the loading plate 210 to move up and down. After the transfer end removes a sheet, the electric lead screw 220 can drive the loading plate 210 to move up by the height of a sheet, so that the transfer end reaches the topmost sheet after moving down the same distance each time, and adsorbs and transfers the topmost sheet, thus improving the stability during work.

[0032] The transfer assembly mainly forms a transfer end that can move up and down to adsorb the sheet. There are various ways to transfer the sheet by the transfer end. It can be by clamping the sheet. In this embodiment, the transfer assembly includes a transfer lifting driving member 270, a transfer translation driving member 290, and a transfer suction cup 280. The transfer translation driving member 290 is connected to the frame 100. The transfer lifting driving member 270 is arranged on the transfer translation driving member 290. The transfer translation driving member 290 can drive the transfer lifting driving member 270 to move in the direction close to or away from the loading plate 210. The transfer lifting driving member 270 is drivingly connected to a lifting plate, and the transfer lifting driving member 270 can drive the lifting plate to move up and down. The transfer suction cup 280 is connected to the lifting plate, and the transfer suction cup 280 is the transfer end. The transfer translation driving member 290 and the transfer lifting driving member 270 can provide driving forces for the transfer suction cup 280 to move reciprocally in the translation direction and in the up and down direction. When the sheet needs to be transferred, the transfer lifting driving member drives the transfer suction cup 280 to move down to the topmost sheet, then drives the transfer suction cup 280 to move up to adsorb and separate the topmost sheet, and then moves in the direction away from the loading plate 210 to transfer the sheet to the conveying surface of the transfer mechanism, realizing the loading of the sheet.

[0033] In the above embodiments, directly heating and pressing the sheet by the heating plate 361 easily causes the sheet to shift. Therefore, the forming mechanism further includes a first lifting driving member 351 connected to the frame 100. The first lifting driving member 351 is drivingly connected with a pressing block 352. The first lifting driving member 351 can drive the pressing block 352 to move downward close to or upward away from the sheet supporting member 310. Before the heating plate 361 presses and heats the sheet, the first lifting driving member drives the pressing block 352 to move downward onto the sheet, presses the sheet tightly onto the sheet supporting member 310 first, and then the heating plate 361 heats and bends the sheet. In this way, through the downward positioning of the sheet, the stability during the heating and bending of the sheet can be improved, the shift of the sheet can be reduced, which is beneficial to further improving the bending processing quality.

[0034] The sheet after the bending process can be shaped by natural cooling. In order to improve the shaping effect of the sheet, in this embodiment, the pressing block 352 is provided with an air inlet and a plurality of air blowing holes. The plurality of air blowing holes are respectively communicated with the air inlet. The air inlet is connected to an air outlet source through a pipeline. The air outlet source can be an electromagnetic air blowing valve, an air pump, etc. After the heating plate 361 finishes heating and bending the sheet, the heating plate 361 moves upward. At this time, the air outlet source supplies air to the plurality of air blowing holes through the air inlet hole, blows air on the sheet to cool it, which is beneficial to quickly shaping the sheet and reducing the influence on the bending quality of the sheet during the subsequent next operation on the sheet.

[0035] By setting different structures of the forming die, the sheet can be bent upward or downward. As the first embodiment of the forming die, it is used to bend the sheet upward. Specifically, as Figure 3 shown in Figure 4 , the forming die includes a bottom die 321 and a side die 322. The bottom die 321 is connected to the frame 100. The side die 322 is arranged on the frame 100 on the side of the bottom die 321 away from the sheet supporting member 310. The height of the side die 322 is greater than the height of the bottom die 321. The heating plate 361 can move downward close to or upward away from the side die 322. When the sheet needs to be bent, the pressing block 352 moves downward close to the sheet and presses the sheet tightly onto the sheet supporting member 310. And a bending forming concave angle is formed between the side die 322 and the bottom die 321. The heating plate 361 moves downward to heat the position of the sheet that needs to be bent. And as the heating plate 361 presses the sheet downward, it can be bent and formed at the concave angle position formed by the bottom die 321 and the side die 322, so that the main body part of the sheet is located on the bottom die 321, and the bent position of the sheet abuts against the side die 322, completing the upward bending of the sheet.

[0036] In order to improve the bending effect on the sheet, in this embodiment, the forming die 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 die 322 away from the bottom die 321. 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 die 322. The first translation driving member 331 can drive the first slider 332 to approach the side die 322 and move the bending plate 333 to directly above the bottom die 321, or drive the first slider 332 away from the side die 322 and move the bending plate 333 out of the position directly above the bottom die 321. After the heating plate 361 heats and bends the sheet, 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 to assist in forming the sheet. When the heating plate 361 moves upward, it is not easy to damage the bending position of the sheet during subsequent processes such as blowing air to cool the sheet. In addition, when the heating plate 361 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 inward, so as to form a larger angle for the sheet bending, improving the processing quality of the sheet and the bending angle of the sheet.

[0037] In order to facilitate the transfer mechanism to push the sheet onto the forming die, two first limiting frames 334 are connected to the frame 100. The two first limiting frames 334 are respectively connected to a guide plate 335. The guide plate 335 is located above the bending plate 333. A first limiting area is formed between the two guide plates 335. Guide rounded corners are respectively provided at the side corners of the two guide plates 335 facing each other. Similarly, in the first embodiment, a guide plate 335 can also be provided. At this time, the guide plate 335 is directly installed above the side die 322. When transferring the sheet to the processing position, it can be moved into the position between the two guide plates 335. When moving between the two guide plates 335, the guide rounded corners at one end of the two guide plates 335 can be used to guide the movement of the sheet, so that the sheet can be smoothly moved into the first limiting area. By limiting the two sides of the sheet with the two guide plates 335, the accuracy of the sheet transfer to the processing position can be improved.

[0038] As Figure 5As shown in the figure, as the second embodiment of the forming die, the forming die includes a lower bending fixed die 341 and a lower bending movable die 342. The lower bending fixed die 341 is connected to the frame 100. A bending protrusion 343 extending in a direction away from the sheet supporting member 310 is provided on the top side of the lower bending fixed die 341. The lower bending movable die 342 can be close to or away from directly below the bending protrusion 343 on the frame 100. The heating plate 361 can move downward close to or upward away from the lower bending fixed die 341. In practical applications, a forming translation driving member 344 is connected to the frame 100. The forming translation driving member 344 is drivingly connected to the lower bending movable die 342. The forming translation driving member 344 drives the lower bending movable die 342 to move in a direction close to or away from directly below the bending protrusion 343. When the sheet needs to be bent, the pressing block 352 moves downward close to the sheet and presses the sheet against the sheet supporting member 310. The heating plate 361 in the heating assembly moves downward close to the sheet to heat the sheet. And the heating plate 361 continues to press downward to bend the sheet along the lower bending fixed die 341. Then the heating plate 361 moves upward to reset. And the lower bending movable die 342 moves on the frame 100 in a direction close to the bending protrusion 343 to continue bending the bending position of the sheet. According to different bending requirements, the lower bending movable die 342 can be moved to different positions to meet the bending requirements of different angles of the sheet. For example, when the lower bending movable die 342 is moved to a position on the side of the bending protrusion 343, a bending within 90 degrees can be achieved for the sheet. When the lower bending movable die 342 is moved to directly below the bending protrusion 343, a bending within the angle range of 90 degrees to 180 degrees can be achieved for the sheet. After completion, the lower bending movable die 342 moves away from the bending protrusion 343 to prepare for bending the next workpiece. Thus, after heating and then bending the sheet, the bending position is not easy to rebound after forming, effectively improving the quality of bending processing of sheets such as mylar sheets and insulating sheets. And it is not necessary to design different dies according to different bending angles, reducing production costs and improving production efficiency.

[0039] In order to further improve the cooling effect on the sheet, in this embodiment, a second air inlet and a plurality of second air blowing holes are provided on the lower bending movable die 342. The plurality of second air blowing holes are respectively communicated with the second air inlet. The second air inlet is connected to a second air outlet source through a pipeline. When the bending of the sheet is completed, the sheet can also be cooled by blowing air through the lower bending movable die 342. Specifically, the second air outlet source supplies air to the plurality of second air blowing holes through the second air inlet hole to blow air on the sheet for cooling, which is beneficial to quickly shaping the sheet and reducing the influence on the bending quality of the sheet during the subsequent next operation on the sheet.

[0040] In both the first and second embodiments of the forming die, in actual use, the number of forming dies can be one, or two or more. The number of heating plates 361 is equal to the number of forming dies and is respectively disposed above the forming dies. For example, if the number of forming dies is two, the two sides of the sheet can be bent upward or downward simultaneously. Additionally, the forming dies of the first and second embodiments can be respectively disposed on both sides of the sheet supporting member 310, as Figure 6 shown, bending one side of the sheet upward and the other side of the sheet downward.

[0041] The transfer mechanism is mainly used to transfer the sheet taken out from the transfer end to the sheet supporting member 310. In this embodiment, the transfer mechanism includes a belt conveyor 410, a second lifting driving member 420, and a second translation driving member 430. The belt conveyor 410 is connected to the frame 100 at a position between the loading plate 210 and the sheet supporting member 310. The belt conveyor 410 has a conveying surface moving from the loading plate 210 towards the sheet supporting member 310. A conveying gap is provided on the conveying surface. The second translation driving member 430 is connected to the frame 100, and the second lifting driving member 420 is disposed on the second translation driving member 430. The second translation driving member 430 can drive the second lifting driving member 420 to move back and forth between the conveying surface and the sheet supporting member 310. The second lifting driving member 420 is drivingly connected to a dial rod 440, and the second lifting driving member 420 can drive the dial rod 440 to move downward into or upward out of the conveying gap. The transfer end places the separated sheet on the conveying surface, and the conveying surface conveys the sheet towards the sheet supporting member 310. When the sheet moves to the end of its conveyance on the conveying surface, the second lifting driving member 420 drives the dial rod 440 to move downward into the conveying gap, and the second translation driving member 430 drives the dial rod 440 to move towards the sheet supporting member 310 to dial the sheet onto the sheet supporting member 310, realizing the feeding of the sheet onto the sheet supporting member 310. After completion, the second lifting driving member drives the dial rod 440 to move upward out of the conveying gap, and the second translation driving member 430 drives the dial rod 440 to return to its original position to prepare for the next dialing of the sheet.

[0042] The transfer component is mainly used to take out and blank the bent sheet. In this embodiment, the transfer component includes a third translation driving member 510 and a third lifting driving member 520. The third translation driving member 510 is connected to the third lifting driving member 520. The third translation driving member 510 can drive the third lifting driving member 520 to move back and forth between the sheet supporting member 310 and the blanking plate. The third lifting driving member 520 is drivingly connected to a blanking suction cup 530. The third lifting driving member 520 can drive the blanking suction cup 530 to move downward close to or upward away from the sheet supporting member 310. The third translation driving member 510 and the third lifting driving member can respectively provide the driving force for the blanking suction cup 530 to move reciprocally in translation and move up and down. After the bending of the sheet is completed, the blanking suction cup 530 moves downward to the sheet supporting member 310 and moves the sheet upward, and then transfers it above the blanking plate. After releasing the adsorption force of the blanking suction cup 530 on the sheet, the sheet falls onto the blanking plate, completing the blanking of the bent sheet.

[0043] In order to further improve the convenience of collecting the sheets after blanking, in this embodiment, the blanking mechanism includes a fourth lifting driving member 540, a fourth translation driving member 550 and an anti - tipping side plate 560. The fourth lifting driving member 540 is connected between the blanking plate and the frame 100. The fourth lifting driving member 540 can drive the blanking plate to move up and down. The anti - tipping side plates 560 are respectively connected to two sides of the blanking plate on the frame 100. An avoidance groove is provided at a position between the two anti - tipping side plates 560 on the top side of the blanking plate. The fourth translation driving member 550 is connected to the frame 100. The fourth translation driving member 550 is drivingly connected to a push plate 551. A push block that can enter the avoidance groove is provided at the bottom side of the push plate 551. The fourth translation driving member 550 can drive the push plate 551 to enter or exit between the two anti - tipping side plates 560. The two anti - tipping side plates 560 are located on both sides of the blanking plate. The sheets are placed on the blanking plate. The two anti - tipping side plates 560 can prevent the sheets from tipping to both sides, so that the sheets placed on the blanking plate can be gradually stacked upward. When stacked to a certain height, the fourth lifting driving member drives the blanking plate to move downward, and then the fourth translation driving member 550 drives the push plate 551 to enter between the two anti - tipping side plates 560, and the push block at the bottom side of the push plate 551 enters the avoidance groove. As the push plate 551 moves between the two anti - tipping side plates 560, the stacked sheets can be pushed outwards. The push block at the bottom side of the push plate 551 moves in the avoidance groove, and the sheet at the bottommost side of the blanking plate can also be pushed outwards. In this way, it is convenient to collect the bent sheets, improving the overall processing efficiency.

[0044] In practical applications, the blank holding lifting drive member, the forming lifting drive member 362, the transfer lifting drive member 270, the transfer translation drive member 290, the first lifting drive member 351, the second lifting drive member 420, the third lifting drive member 520, the fourth lifting drive member 540, the first translation drive member 331, the second translation drive member 430, the third translation drive member 510, and the fourth translation drive member 550 are all used to provide the driving force for linear movement, and there are various structural forms, such as cylinders, hydraulic cylinders, or electric push rods, etc.
