Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, and particularly to a hot forming and bending device for strip-shaped metal sheets. Background Art

[0002] In the field of metal processing, the metal sheet bending process is an indispensable core link, widely used in key industries such as automobiles, construction, household appliances, and aerospace. Taking strip-shaped metal sheets as an example, the traditional processing process includes multiple steps such as loading, local heating, bending and forming, and discharging. Most of these steps rely on manual operation. Not only does each process require specialized personnel, but the coordination between processes is also extremely cumbersome, resulting in huge consumption of human resources and low processing efficiency.

[0003] For example, the hot forming and bending device for strip-shaped metal sheets with the publication number CN109731972A in the prior art can automatically complete a series of processing steps such as high-frequency local heating, stamping and bending, and discharging during the transmission process, achieving the purpose of stable processing quality and fast processing speed. However, the conveying method and bending link adopted are only applicable to the bending treatment of obtuse angles. For acute angles with smaller angles, it is difficult to achieve fast bending treatment, and during the bending process, the effect of automatic feeding cannot be achieved, greatly limiting the convenience of its processing.

[0004] In view of the above technical defects, a solution is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a hot forming and bending device for strip-shaped metal sheets to solve the above-mentioned technical defects.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A hot forming and bending device for strip-shaped metal sheets includes a fixed table. A fixed seat is fixedly connected to the top of the fixed table, and an alternating feeding mechanism and an adjustable bending mechanism are arranged on the fixed seat. On both sides of the top of the fixed table, feeding frames are symmetrically and fixedly connected, and a pushing plate is arranged in the feeding frame.

[0007] The alternating feeding mechanism includes a rotating belt, and a material blocking sliding table fixedly installed on both sides of the rotating belt and slidingly contacting the corresponding feeding frame. A groove seat adapted to the strip-shaped metal sheet is detachably installed on one side of the material blocking sliding table. The adjustable pushing plate includes a mounting seat, and clamping rollers are symmetrically installed at the bottoms of both sides of the mounting seat. A rotating shaft is rotatably installed at the top of the mounting seat, and a bending rod is movably installed through a bending seat on the rotating shaft. Limiting seats cooperating with the clamping rollers are symmetrically arranged on both sides of the fixed seat.

[0008] Preferably, a positioning seat adapted to the strip-shaped metal plate is detachably installed at the bottom inside the feeding frame. A plurality of guide rods slidably connected to the feeding frame are fixedly connected to the pushing plate, and a plurality of pushing springs are connected between the pushing plate and the feeding frame.

[0009] Preferably, an induction coil is connected through a mounting block to one side of the feeding frame close to the limit seat, and a high-frequency furnace connected to the induction coil is bolt-mounted on the top of the fixed seat.

[0010] Preferably, two groups of rotating rollers are rotatably installed on the fixed seat, and the two groups of rotating rollers are connected by a rotating belt. A servo motor for driving the corresponding rotating roller to rotate is bolt-mounted at the bottom of the fixed seat, and the material-blocking sliding table is slidably connected to the fixed seat.

[0011] Preferably, a gearbox for driving the rotating shaft to rotate at a reduced speed is installed on the top of the fixed seat. A bending motor matched with the gearbox is installed on the gearbox. The rotating shaft is fixedly connected to the bending seat through a semi-circular disk, and a plurality of threaded holes for threadedly connecting the bending rods are equidistantly arranged on the bending seat.

[0012] Preferably, sliding grooves are symmetrically formed on both sides of the mounting seat, and adjusting blocks rotatably connected to the clamping rollers are slidably connected in the sliding grooves. A reset tension spring is fixedly connected between the adjusting blocks and the sliding grooves, and a self-locking component for cooperating with the semi-circular disk is arranged on the top of the adjusting block.

[0013] Preferably, the self-locking component includes a toothed plate. A cavity for the toothed plate to slide is formed at the top inside the sliding groove. A limit post slidably connected to the mounting seat is fixedly connected to the top of the toothed plate, and a tooth groove for cooperating with the toothed plate is formed on the top of the adjusting block.

[0014] Preferably, a spring cavity is formed on the inner wall of one side of the limit seat far from the fixed seat, and a plurality of limit blocks distributed in a rectangular array are slidably connected in the spring cavity. A limit spring is fixedly connected between the limit blocks and the spring cavity, and an arc-shaped guiding surface is formed on one side of the limit block close to the feeding frame.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) In the present invention, the strip-shaped metal plates are first stored through two groups of feeding frames, and the feeding and material feeding are synchronously carried out by cooperating with the two groups of material-blocking sliding tables carrying the groove seats to reciprocate alternately. Then, combined with the induction coil on one side of the feeding frame and the forward and reverse deflection of the bending rods, the strip-shaped metal plates are subjected to an integrated and rapid bending treatment of automatic feeding, processing and discharging. In addition, the bending angle and radian are adjusted by adjusting the deflection angle and position of the bending rods. Moreover, through the detachably installed positioning seat and the groove seat, the bending treatment of different types of strip-shaped metal plates is realized, which can further improve the application range of the device;

[0017] (2) During the process of the strip-shaped metal sheet being carried by the groove base in the present invention, some of the limit blocks in the limit seat come into contact with the strip-shaped metal sheet and move to compress the corresponding limit springs. On the one hand, it realizes the preliminary clamping during the movement process to avoid the problem of dropping. On the other hand, the limit blocks that do not come into contact with the strip-shaped metal sheet restrict the up and down movement of the strip-shaped metal sheet to avoid the problem of skew bending affecting the bending quality. In addition, the provided clamping rollers can adaptively clamp different types of strip-shaped metal sheets in cooperation with the fixed seat. After that, in cooperation with the rotation of the semi-circular disk, the position of the clamping rollers is fixed independently, and combined with the limit seat, the position of the strip-shaped metal sheet is fixed during the bending process, further realizing the precise bending treatment of different types of strip-shaped metal sheets.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1 - 6 As shown, to solve the problem in the prior art that it is difficult to perform multi-type angle bending treatment on strip-shaped metal plates, the following solutions can be adopted;

[0033] In this embodiment, a hot forming and bending device for strip-shaped metal plates includes a fixed table 1. A fixed seat 11 is fixedly connected to the top of the fixed table 1, and an alternating feeding mechanism 2 and an adjustable bending mechanism 3 are arranged on the fixed seat 11. Two sides of the top of the fixed table 1 are symmetrically and fixedly connected with feeding frames 12. The top and the side close to the fixed seat 11 of the feeding frame 12 are open for placing and pushing out strip-shaped metal plates, and a pushing plate 13 is arranged in the feeding frame 12 for pushing out the placed strip-shaped metal plates one by one from the feeding frame 12;

[0034] The alternating feeding mechanism 2 includes a rotating belt 21 and retaining slide tables 22 fixedly installed on both sides of the rotating belt 21 and slidingly contacting the corresponding feeding frames 12. The provided retaining slide tables 22 are used to temporarily block the strip-shaped metal plates in the feeding frames 12 during the feeding process of the groove seats 23. A groove seat 23 adapted to the strip-shaped metal plates is detachably installed on one side of the retaining slide table 22. The corresponding groove seat 23 is selected according to the shape of the strip-shaped metal plate to be bent and connected to the retaining slide table 22. The connection method is bolt or snap connection to realize the feeding treatment of different types of strip-shaped metal plates;

[0035] The adjustable pusher plate 13 includes a mounting base 31, and clamping rollers 32 are symmetrically installed at the bottom of both sides of the mounting base 31. The provided clamping rollers 32 are used to restrict the bending area of the strip-shaped metal sheet, and cooperate with the rotating bending rod 34 to achieve the bending process. A rotating shaft is rotatably installed at the top of the mounting base 31, and the bending rod 34 is movably installed through a bending seat 33 on the rotating shaft. A bending roller is rotatably connected to the outside of the bending rod 34, which avoids the problem that the strip-shaped metal sheet moves during the bending process, thereby causing a low accuracy of the bending area. Limit seats 14 that cooperate with the clamping rollers 32 are symmetrically arranged on both sides of the fixed seat 11 to assist in preventing the strip-shaped metal sheet from falling during the conveying process.

[0036] A positioning seat 15 adapted to the strip-shaped metal sheet is detachably installed at the bottom of the material discharge frame 12. The corresponding positioning seat 15 is selected according to the shape of the strip-shaped metal sheet to be bent and connected to the material discharge frame 12. Its connection method is bolt or snap connection, so as to realize the feeding process of different types of strip-shaped metal sheets, so that they can accurately enter the groove seat 23 after being pushed out and smoothly complete the feeding process. A plurality of guide rods slidably connected to the material discharge frame 12 are fixedly connected to the pusher plate 13 to increase the stability of the movement of the pusher plate 13;

[0037] Moreover, a plurality of pusher springs 16 are connected between the pusher plate 13 and the material discharge frame 12. The pusher springs 16 are sleeved outside the corresponding guide rods. Pull the guide rods to drive the pusher plate 13 to compress the pusher springs 16. Stack a plurality of strip-shaped metal sheets in the material discharge frame 12, and then release the guide rods. The pusher plate 13 pushes the strip-shaped metal sheets to abut against the material blocking slide table 22, and then through the movement of the groove seat 23, the feeding process is automatically completed.

[0038] An induction coil 17 is connected to one side of the material discharge frame 12 close to the limit seat 14 through a mounting block. A high-frequency furnace (not shown in the figure) connected to the induction coil 17 is bolt-mounted on the top of the fixed seat 11. The bending part of the strip-shaped metal sheet is located at the position of the induction coil 17, and the high-frequency furnace heats the bending area through the induction coil 17.

[0039] Two groups of rotating rollers 24 are rotatably installed on the fixed seat 11, and the two groups of rotating rollers 24 are connected by a rotating belt 21. A number of tooth blocks (not shown in the figure) are arranged on the outer side wall of the rotating roller 24, and a card slot (not shown in the figure) is opened on the rotating belt 21 to avoid the problem of relative sliding between the rotating roller 24 and the rotating belt 21, thereby improving the accuracy of feeding. A servo motor 25 for driving the corresponding rotating roller 24 to rotate is bolt-mounted at the bottom of the fixed seat 11, and the material blocking slide table 22 is slidably connected to the fixed seat 11;

[0040] The servo motor 25 drives the corresponding rotating roller 24 to rotate, and the rotating belt 21 drives the rotating belt 21 to rotate, prompting the side material blocking slide 22 to move away from the limit seat 14 until the groove seat 23 moves to one side of the feeding frame 12. Under the compression of the pushing spring 16, the pushing plate 13 pushes a strip-shaped metal plate into the groove seat 23. The servo motor 25 drives the rotating roller 24 to rotate in the reverse direction, and the groove seat 23 containing the strip-shaped metal plate moves closer to the limit seat 14. During this process, another groove seat 23 follows the corresponding material blocking slide 22 to move in the reverse direction for the feeding process, thereby improving the bending processing efficiency.

[0041] A gearbox 35 for driving the rotating shaft to rotate at a reduced speed is installed on the top of the fixed seat 11. A bending motor 36 that cooperates with it is installed on the gearbox 35. The output shaft of the gearbox 35 is fixedly connected to the rotating shaft, and the output shaft of the bending motor 36 is connected to the input shaft of the gearbox 35. The set gearbox 35 can increase the torque of the rotating shaft rotation, thereby realizing the bending effect of the strip-shaped metal plate.

[0042] The rotating shaft is fixedly connected to the bending seat 33 through a semi-circular disk 37. The bending motor 36 drives the internal gears of the gearbox 35 to rotate, and then prompts the rotating shaft to rotate slowly. The rotating shaft drives the bending seat 33 to carry the bending rod 34 to rotate through the semi-circular disk 37. The bending rod 34 contacts the strip-shaped metal plate, and cooperates with the clamping roller 32 to perform bending treatment on the strip-shaped metal plate. The bending angle is controlled by the angle of deflection of the rotating shaft driven by the bending motor 36. A plurality of threaded holes threadedly connected to the bending rod 34 are equidistantly arranged on the bending seat 33. By connecting the bending rod 34 to the threaded holes at different positions on the bending seat 33, the bending arc is adjusted.

[0043] Embodiment 2: Please refer to Figures 5 - 8 As shown, for the problem that when only the groove seat is used to carry the strip-shaped metal plate for feeding, it is easy to have the problem of feeding inclination and reducing the bending accuracy, the following solution can be adopted;

[0044] In this embodiment, sliding grooves are symmetrically opened on both sides of the mounting seat 31, and an adjusting block 38 rotatably connected to the clamping roller 32 is slidably connected in the sliding grooves. A return spring 39 is fixedly connected between the adjusting block 38 and the sliding grooves. When the strip-shaped metal plate contacts the clamping roller 32, it pushes the clamping roller 32 to carry the adjusting block 38 to move away from the fixed seat 11, and under the elastic force of the return spring 39, the clamping roller 32 is prompted to combine with the fixed seat 11 to clamp the strip-shaped metal plate, which can adaptively clamp different types of strip-shaped metal plates in cooperation with the fixed seat 11. A self-locking component that cooperates with the semi-circular disk 37 is arranged on the top of the adjusting block 38 to autonomously fix the position of the clamping roller 32 and realize the precise bending treatment of different types of strip-shaped metal plates.

[0045] The self-locking component includes a toothed plate 310. A cavity for the toothed plate 310 to slide is provided at the top inside the chute. A limiting post 311 that slides with the mounting seat 31 is fixedly connected to the top of the toothed plate 310. A tooth groove 312 that cooperates with the toothed plate 310 is provided at the top of the adjusting block 38. When the semi-circular disk 37 does not block the top of the limiting post 311, the strip-shaped metal plate contacts the clamping roller 32. When moving the adjusting block 38, the separation of the toothed plate 310 and the tooth groove 312 can be realized. When the semi-circular disk 37 blocks the top of the limiting post 311, when the adjusting block 38 moves, the separation of the toothed plate 310 and the tooth groove 312 cannot be realized, thereby restricting the movement of the clamping roller 32, and further realizing the precise bending process of different types of strip-shaped metal plates.

[0046] On the inner wall of the side of the limiting seat 14 far from the fixed seat 11, a spring cavity is provided, and a plurality of limiting blocks 18 distributed in a rectangular array are slidably connected in the spring cavity. A limiting spring 19 is fixedly connected between the limiting block 18 and the spring cavity. An arc-shaped guiding surface is provided on the side of the limiting block 18 close to the material feeding frame 12. The groove seat 23 drives the strip-shaped metal plate to move. One end of the strip-shaped metal plate extends into the limiting seat 14, and through the arc-shaped guiding surface on the limiting block 18, the limiting block 18 in contact with the strip-shaped metal plate is urged to compress the corresponding limiting spring 19, realizing the preliminary clamping during the movement of the strip-shaped metal plate and avoiding the problem of dropping.

[0047] The up-and-down movement of the strip-shaped metal plate can be restricted by the limiting blocks 18 that are not in contact with the strip-shaped metal plate, avoiding skewed bending. In addition, the plurality of limiting blocks 18 can also independently restrict the up-and-down movement of strip-shaped metal plates of different shapes. Through the arc-shaped guiding surface on one side of the limiting block 18, the strip-shaped metal plate can move normally when being bent. When the groove seat 23 resets after bending, the separation of the strip-shaped metal plate and the groove seat 23 is smoothly completed.

[0048] Embodiment Three: Please refer to Figures 1 - 8 As shown, the present invention also proposes a use method of a strip-shaped metal plate hot forming and bending device, including the following steps:

[0049] Step One: Select the corresponding positioning seat 15 and groove seat 23 according to the shape of the strip-shaped metal plate to be bent, and connect them to the material feeding frame 12 and the material blocking sliding table 22 respectively. Pull the guide rod to drive the pushing plate 13 to compress the pushing spring 16, place a plurality of strip-shaped metal plates in the material feeding frame 12 for stacking, and then release the guide rod. The pushing plate 13 pushes the strip-shaped metal plate to contact the material blocking sliding table 22.

[0050] Step 2: The servo motor 25 drives the corresponding rotating roller 24 to rotate, and the rotating belt 21 drives the rotating belt 21 to rotate, prompting the material blocking slide 22 on one side to move away from the limit seat 14 until the groove seat 23 moves to one side of the feeding frame 12. Under the compression of the pushing spring 16, the pushing plate 13 pushes a strip-shaped metal sheet into the groove seat 23. The servo motor 25 drives the rotating roller 24 to rotate in the reverse direction, and the groove seat 23 containing the strip-shaped metal sheet moves closer to the limit seat 14. During this process, the other groove seat 23 follows the corresponding material blocking slide 22 to move in the reverse direction for the feeding process;

[0051] Step 3: The groove seat 23 drives the strip-shaped metal sheet to move. One end of the strip-shaped metal sheet extends into the limit seat 14, and through the arc-shaped guiding surface on the limit block 18, the limit block 18 in contact with the strip-shaped metal sheet compresses the corresponding limit spring 19. The limit block 18 not in contact with the strip-shaped metal sheet restricts the up and down movement of the strip-shaped metal sheet to prevent skew bending until the bending area of the strip-shaped metal sheet is located at the position of the induction coil 17. The high-frequency furnace conducts high-frequency heating on the bending area through the induction coil 17. After the hot forming is completed, the strip-shaped metal sheet continues to move through the rotation of the rotating belt 21;

[0052] Step 4: When the strip-shaped metal sheet contacts the clamping roller 32, it pushes the clamping roller 32 to drive the adjusting block 38 to move away from the fixed seat 11. Under the elastic force of the reset tension spring 39, the clamping roller 32 and some of the limit blocks 18 that compress the limit spring 19 are combined with the fixed seat 11 to clamp the strip-shaped metal sheet. When the bending area of the strip-shaped metal sheet moves to the position of the clamping roller 32, the bending motor 36 drives the gears inside the gearbox 35 to rotate, and then prompts the rotating shaft to rotate slowly. The rotating shaft drives the bending seat 33 to carry the bending rod 34 to rotate through the semi-circular plate 37. By using the semi-circular plate 37 to block the top of the limit post 311, the separation of the toothed plate 310 from the tooth groove 312 on the adjusting block 38 is restricted, thereby restricting the movement of the clamping roller 32;

[0053] The bending rod 34 contacts the strip-shaped metal sheet and, in cooperation with the clamping roller 32 with a fixed position, bends the strip-shaped metal sheet. The bending angle is controlled by the angle of deflection of the rotating shaft driven by the bending motor 36. By connecting the bending rod 34 to different position threaded holes on the bending seat 33, the bending arc is adjusted;

[0054] Step Five: After the current strip-shaped metal sheet is bent, through the re-same-direction movement of the material stop sliding table 22, the strip-shaped metal sheet is separated from the limiting block 18 in the limiting seat 14. Then, the servo motor 25 drives the rotating belt 21 to rotate in the reverse direction to perform alternate feeding and material conveying processes. In combination with the reverse rotation of the bending motor 36 and the clamping roller 32 on the other side of the fixed seat 11, the next strip-shaped metal sheet is bent. The strip-shaped metal sheet conveyed in the subsequent feeding process pushes the previously bent strip-shaped metal sheet to move, so that it is separated from the clamping roller 32 to complete automatic unloading.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
