Description

Technical Field

[0001] This invention relates to the field of profile processing technology, and in particular to a toothed edge-folding device for profiles. Background Technology

[0002] 3D illuminated signs are a common form of advertising for businesses, offering advantages such as an attractive and high-end appearance and relatively low cost, making them a top choice for advertising in recent years. The main work in producing the edges of 3D illuminated signs is the edging process, which primarily involves folding and bending. Traditional bending, done manually, is difficult to guarantee in terms of quality and is inefficient, so it has gradually been replaced by bending machines. Bending machines include feeding devices, cutting devices, and bending devices; however, for some special profiles, traditional bending machines can encounter problems after bending.

[0003] Some local regulations require that 3D illuminated signs for advertising have specific requirements, namely, the outward-facing side of the profile must cover the embedded illuminated sign to ensure its fixation. This necessitates folding one edge of the profile to cover the internal illuminated sign. However, during processing, bending the profile can cause deformation or interference at the folded edge, requiring manual adjustment. This necessitates punching serrations into the profile beforehand, which reduces the gap between the serrations at the bending points, again requiring manual adjustment and reducing work efficiency. It also affects the appearance of the profile. Furthermore, cutting the profile after processing results in an excessively large cutting mechanism height or length, impacting the overall equipment. Existing equipment that cuts the profile before it is fully formed affects the material transport, or necessitates adding a transport mechanism, increasing equipment costs. Summary of the Invention

[0004] The problem solved by this invention is to provide a toothed and folding device for profiles, which can punch, fold, and cut profiles at different angles according to actual needs, realize multi-functional integrated processing of profiles, and ensure the aesthetics and forming effect of profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A profile shearing and folding device includes a mounting plate, on which, from front to back, are arranged a feeding mechanism for conveying the profile, a grooving mechanism for slotting the profile, a punching mechanism for punching the profile, a folding mechanism for folding the profile, a pre-cutting mechanism for semi-cutting the profile, a bending mechanism for bending the profile, and a post-cutting mechanism for cutting the profile.

[0007] The punching and swinging tooth mechanism includes a limiting clamp plate located on the upper part of the mounting plate. The limiting clamp plates form a punching tooth gap for the profile to pass through. The left and right sides of the limiting clamp plate are provided with mutually cooperating punching toothers and swinging toothers.

[0008] The punching device includes a punching seat located on the upper part of the mounting plate, a punching motor mounted on the punching seat, a punching gear rotatably mounted on the upper part of the punching seat and powered by the punching motor, a punching eccentric rod slidably mounted on the punching seat, one end of the punching eccentric rod being rotatably connected to the non-center part of the punching gear, and the other end of the punching eccentric rod being provided with a rotatable punching cutter with a triangular cross-section, and a stabilizing seat rotatably mounted on the limiting clamp plate on the punching cutter;

[0009] The oscillating gear includes an oscillating gear disk rotatably mounted on the limiting clamp and connected to the lower part of the stabilizing seat. The limiting clamp is provided with an oscillating gear motor that is poweredly connected to the oscillating gear disk. The oscillating gear disk has a limiting hole for inserting a punch cutter.

[0010] As an improved technical solution, a punch slider is installed at the lower part of the punch eccentric rod, a punch slide rail that cooperates with the punch slider is provided on the upper part of the punch seat, a positioning seat is installed on the end of the punch eccentric rod near the limiting clamp, a positioning rod extending towards the limiting clamp is provided on the positioning seat, a positioning block is rotatably installed on the positioning rod, and the punch cutter is fixedly installed at the end of the positioning block.

[0011] As an improved technical solution, the folding mechanism includes a folding plate on the mounting plate located on the right side of the limiting clamp. A folding motor is mounted on the folding plate, and a folding gear, power-connected to the folding motor, is rotatably mounted on the upper part of the folding plate. A folding eccentric rod is rotatably connected to the non-center portion of the folding gear. An L-shaped pusher is provided at the end of the folding eccentric rod. The lower part of the L-shaped pusher is slidably connected to the folding plate, and a folding roller is embedded in the upper part of the L-shaped pusher.

[0012] As an improved technical solution, the limiting clamp is provided with a folding through hole for passing through the L-shaped pusher. Folding supports are fixedly installed in the folding through hole and are respectively provided on the front and rear sides of the L-shaped pusher. The folding supports are provided with a support groove for supporting the profile. The lowest horizontal height of the support groove is lower than the highest height of the folding roller. The left side of the folding support is connected by a connecting plate. The lower part of the connecting plate is higher than the highest height of the folding roller. A limiting block is fixedly installed in the support groove on the connecting plate. A gap is formed between the limiting block and the inner wall of the support groove for the profile to pass through.

[0013] As an improved technical solution, a folding cylinder is fixedly installed on the right side of the limiting clamping plate. The piston rod of the folding cylinder is provided with a clamping plate that clamps the profile with the limiting block. The lower part of the clamping plate is higher than the uppermost height of the folding roller.

[0014] The beneficial effects of this invention are that the punching tooth mechanism adjusts the punching tooth angle, enabling toothing of the profile edge to achieve a sawtooth shape at the corresponding angle. The folding mechanism allows the profile edge to bend, reducing the footprint and cost of the processing equipment. Due to the connection between the stabilizing seat and the swinging tooth disc, the swinging of the swinging tooth motor drives the stabilizing seat to swing, which in turn drives the swinging of the punching tooth cutter. Adjusting the punching tooth angle allows for different angles of toothing on the profile, thereby adjusting the gap between the sawtooths. During punching, the operation of the punching tooth motor drives the rotation of the punching tooth gear, which in turn... The eccentric rod of the punch moves, and since it is slidably mounted on the punch holder, it can only move back and forth along the punch holder, thereby driving the punch cutter to punch the profile. Although the punch cutter is rotatably mounted on the eccentric rod, due to the connection between the stabilizing seat and the swing tooth plate, the punch cutter can only swing when the swing tooth motor is running. When the swing tooth motor is not rotating, the swing tooth plate will not rotate, so the punch cutter will not rotate. It can punch, fold, and cut the profile at different angles according to actual needs, realizing multi-functional integrated processing of the profile and ensuring the aesthetics and forming effect of the profile.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To facilitate understanding of this patent, the existing profiles are described. Due to certain local regulations, three-dimensional illuminated signs for advertising have fixed requirements; that is, the outward-facing surface of the profile needs to shield the embedded illuminated signs to ensure their fixation. Therefore, one edge of the profile needs to be folded to shield the internal illuminated signs. (Refer to...) Figure 7 As shown, the upper part is an arc-shaped plate, the side part is a straight plate, and the lower part is a horizontal plate. First, the edges of the profile need to be folded, and then punched and bent separately. The arc-shaped plate needs to be punched and then bent. The processing between the arc-shaped plate and the straight plate also requires punching and then bending. The right-angle bend between the straight plate and the horizontal plate is also different. The punching angle of the arc-shaped plate bending by itself, the punching angle of the arc-shaped plate bending with the straight plate, and the punching angle of the straight plate bending with the horizontal plate are all different, and the punching shape of the profile is different.

[0025] For ease of description, Figure 2 The left is the front. Figure 2 The top is to the right. Figure 2 The vertical plane of the paper facing outwards is considered upwards. To solve the above problem, refer to... Figures 1-6 As shown, the profile shearing and folding device includes a mounting plate 1, on which a punching mechanism for punching the profile and a folding mechanism for folding the profile are arranged sequentially from front to back.

[0026] The punching and swinging gear mechanism enables the controllability of the punching gears. The mechanism includes a limiting clamp plate on the upper part of the mounting plate 1, with the limiting clamp plates forming a punching gap for the profile to pass through. The left and right sides of the limiting clamp plate are equipped with cooperating punching and swinging gears. Each punching gear includes a punching seat 401 on the upper part of the mounting plate 1, a punching motor 402 on the punching seat 401, a punching gear 403 rotatably mounted on the upper part of the punching seat 401 and powered by the punching motor 402, a punching eccentric rod 404 slidably mounted on the punching seat 401, a punching slider mounted on the lower part of the punching eccentric rod 404, and a matching punching slider on the upper part of the punching seat 401. The punch slide rail 406 is assembled. One end of the punch eccentric rod 404 is rotatably connected to the non-center part of the punch gear 403. The other end of the punch eccentric rod 404 is provided with a rotatable punch cutter 407 with a triangular cross section. A positioning seat 408 is installed on the end of the punch eccentric rod 404 near the limiting clamp. The positioning seat 408 is provided with a positioning rod 409 extending towards the limiting clamp. A positioning block 410 is rotatably installed on the positioning rod 409. In this embodiment, the end of the positioning rod 409 is provided with two positioning discs. The positioning block 410 is fitted on the positioning rod 409 between the positioning discs. The punch cutter 407 is fixedly installed on the end of the positioning block 410. A stabilizing seat 411, rotatably mounted on a limiting clamp, is fitted onto the punch cutter 407. The punch of the punching mechanism can achieve a serrated edge on the profile. The operation of the punching motor 402 drives the rotation of the punching gear 403, which in turn moves the punching eccentric rod 404. Since the punching eccentric rod 404 is slidably mounted on the punching seat 401, it can only move back and forth along the punching seat 401, thereby driving the punch cutter 407 to punch the profile. Although the punch cutter 407 is rotatably mounted on the punching seat... On the eccentric rod 404, but due to the connection between the stabilizer 411 and the swing tooth disk 412, the swing tooth motor 413 does not rotate, and the swing tooth disk 412 will not rotate. Therefore, the punch cutter 407 will not rotate. At the same time, a zeroing switch for controlling the punch cutter to return to zero can be installed on the mounting plate. The swing tooth device includes a swing tooth disk 412 rotatably mounted on the limit clamp and connected to the lower part of the stabilizer 411. The limit clamp is provided with a swing tooth motor 413 that is poweredly connected to the swing tooth disk 412. The swing tooth disk 412 has a limit hole 414 for inserting the punch cutter 407. When the saw teeth of the profile need to be adjusted, the tooth-splitting mechanism inserts the tooth-splitting cutter 407 into the limiting hole 414 of the tooth-splitting disk 412 during tooth-splitting. The operation of the tooth-splitting motor 413 drives the tooth-splitting disk 412 to rotate. The rotation of the tooth-splitting disk 412 drives the tooth-splitting cutter 407 to swing. The swing of the tooth-splitting cutter 407 will cut the profile, thereby adjusting the shape of the saw teeth. At the same time, a zeroing switch for controlling the tooth-splitting mechanism to return to zero can be installed on the mounting plate.

[0027] After punching, the profile is sent to the folding mechanism. The folding mechanism includes a folding plate 501 on a mounting plate 1 located on the right side of the limiting clamp. A folding motor 502 is mounted on the folding plate 501. A folding gear 503, which is powered by the folding motor 502, is rotatably mounted on the upper part of the folding plate 501. A folding eccentric rod 504 is rotatably connected to the non-center part of the folding gear 503. An L-shaped pusher 505 is provided at the end of the folding eccentric rod 504. The lower part of the L-shaped pusher 505 is slidably connected to the folding plate 501. A slide rail is provided on the folding plate 501. A slider that cooperates with the slide rail is provided at the lower part of the L-shaped pusher 505. A folding roller 506 is embedded in the upper part of the L-shaped pusher 505. A folding through hole for passing through the L-shaped pusher 505 is provided on the limiting clamp. Folding rollers 506 are fixedly installed in the folding through hole. The L-shaped pusher 505 has folding edge supports 507 on both the front and rear sides. The folding edge supports 507 have support grooves for supporting the profile. The lowest horizontal height of the support groove is lower than the highest height of the folding roller 506. The left side of the folding edge support 507 is connected by a connecting plate. The lower part of the connecting plate is higher than the highest height of the folding roller 506. A limiting block 508 is fixedly installed on the connecting plate in the support groove. The limiting block 508 and the inner wall of the support groove form a gap for the profile to pass through. A folding edge cylinder 510 is fixedly installed on the right side of the limiting clamping plate. The piston rod of the folding edge cylinder 510 is provided with a clamping plate 509 that clamps the profile with the limiting block 508. The lower part of the clamping plate 509 is higher than the highest height of the folding roller 506. Meanwhile, a zeroing switch for controlling the folding mechanism to return to zero can be installed on the mounting plate. During folding, the folding cylinder 510 extends and drives the clamping plate 509 to cooperate with the limiting block 508 to clamp the profile. The operation of the folding motor 502 drives the rotation of the folding gear 503. The rotation of the folding gear 503 drives the folding eccentric rod 504 to move. The movement of the folding eccentric rod 504 drives the L-shaped pusher 505 to move. Since the L-shaped pusher 505 is slidably mounted on the folding plate 501, the L-shaped pusher 505 can only move back and forth along the folding plate 501, thereby driving the folding roller 506 to fold the profile.

[0028] In use, the punching tooth mechanism can punch the edge of the profile. The operation of the punching tooth motor 402 drives the rotation of the punching tooth gear 403, which in turn drives the punching tooth eccentric rod 404 to move. Since the punching tooth eccentric rod 404 is slidably mounted on the punching tooth seat 401, it can only move back and forth along the punching tooth seat 401, thereby driving the punching tooth cutter 407 to punch the profile. Although the punching tooth cutter 407 is rotatably mounted on the punching tooth eccentric rod 404, the stabilizing seat 411 and the swing tooth disk 412... When the oscillating tooth motor 413 is not rotating, the oscillating tooth disk 412 will not rotate, so the punching cutter 407 will not rotate. At the same time, the punching oscillating tooth mechanism can process saw teeth of the corresponding angle. When the saw teeth of the profile need to be adjusted, the punching cutter 407 will be inserted into the limiting hole 414 of the oscillating tooth disk 412 during the punching process. The operation of the oscillating tooth motor 413 drives the oscillating tooth disk 412 to rotate. The rotation of the oscillating tooth disk 412 drives the punching cutter 407 to swing. The swinging of the punching cutter 407 will cut the profile, thereby adjusting the gap between the saw teeth. The folding mechanism enables the profile edge to bend. During folding, the folding cylinder 510 extends, driving the clamping plate 509 to cooperate with the limiting block 508 to clamp the profile. The operation of the folding motor 502 drives the folding gear 503 to rotate. The rotation of the folding gear 503 drives the folding eccentric rod 504 to move. The movement of the folding eccentric rod 504 drives the L-shaped pusher 505 to move. Since the L-shaped pusher 505 is slidably mounted on the folding plate 501, it can only move back and forth along the folding plate 501, thereby driving the folding roller 506 to fold the profile. This reduces the footprint and cost of the processing equipment, and allows for punching, folding, and cutting of profiles at different angles according to actual needs, achieving multi-functional integrated processing of profiles and ensuring the aesthetics and forming effect of the profiles.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
