Description

Technical Field

[0001] This invention relates to the field of profile processing technology, and in particular to a bending device suitable for various bending curvatures. 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 involved in producing the edges of 3D illuminated signs is the edging process, which primarily includes 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bending, done manually, is difficult to guarantee in terms of quality and is inefficient, so it has gradually been replaced by bending machines.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, cutting, and bending devices. However, for some special profiles, traditional bending machines present problems. When bending profiles to create edging, existing bending machines use the distance between the centers of the bending rollers as the bending radius. Since multiple bending radii are needed for the edging, multiple bending machines are required to achieve the desired bending shape, increasing equipment purchase costs, floor space requirements, and impacting processing efficiency. Summary of the Invention

[0003] The problem solved by this invention is to provide a bending device applicable to various bending radii, which can bend profiles to different radii according to actual needs, thereby improving work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bending device applicable to various bending radii includes a mounting plate, on which bending mechanisms for bending profiles are sequentially provided.

[0006] The bending mechanism includes a bending driven gear rotatably mounted on the upper part of the mounting plate. The mounting plate is equipped with a bending power component that drives the bending driven gear to rotate. A bending base plate is fixedly mounted on the upper part of the bending driven gear. A positioning bending roller rotatably connected to the bending driven gear is provided on the bending base plate. A vertically arranged bending positioning plate is mounted on one end of the bending base plate. A clamping cylinder and an adjusting cylinder with their extension and retraction directions perpendicularly are provided on one side of the bending positioning plate. A positioning side plate that can slide along the length direction of the bending positioning plate is provided on the front side of the bending positioning plate. The bending positioning plate and the positioning... A reset component is provided between the side plates. The piston rod of the clamping cylinder is connected to the positioning side plate. A front bending roller that cooperates with the positioning bending roller is rotatably installed on the left end of the positioning side plate. A rear bending plate that can slide left and right on the positioning side plate is provided on the rear side of the positioning side plate. The right end face of the rear bending plate is slidably connected to the piston rod of the adjusting cylinder. The distance from the front end face of the rear bending plate to the positioning side plate is not less than the radius of the front bending roller. When the piston rod of the adjusting cylinder extends, the distance between the end face of the rear bending plate and the positioning bending roller is less than the distance between the positioning bending roller and the front bending roller.

[0007] The beneficial effect of this invention is that the bending equipment applicable to various bending arcs can achieve bending of profiles with various radii. When the radius of the arc to be bent is not greater than that of the front bending roller, the clamping cylinder will fix the positioning side plate on the bending positioning plate. Then, the bending power component operates to drive the bending driven gear to rotate. The rotation of the bending driven gear drives the bending base plate to rotate. The rotation of the bending base plate drives the bending positioning plate to rotate. The rotation of the bending positioning plate drives the front bending roller to rotate. Since the positioning bending roller is located at the center of the bending driven gear, the front bending roller bends the profile around the positioning bending roller. When the radius of the arc to be bent is greater than that of the front bending roller, the clamping cylinder extends and retracts to allow the positioning side plate to slide on the bending positioning plate. The piston rod of the adjusting cylinder extends and drives the rear bending plate towards the positioning bending roller. The movement, specifically the sliding of the rear bending plate to the left on the bending positioning plate, occurs when the piston rod of the adjusting cylinder extends. At this point, the distance between the end face of the rear bending plate and the positioning bending roller is less than the distance between the positioning bending roller and the front bending roller. Therefore, the rear bending plate contacts the profile earlier than the front bending roller. Since the rear bending plate, positioning side plate, and rear bending plate are all in a state where they can slide left and right, the friction between the rear bending plate and the profile causes the rear bending plate to move towards the positioning bending roller as it bends the profile, reducing wear on the left end face of the rear bending plate. After bending, the reset component resets the positioning side plate, and the piston rod of the adjusting cylinder retracts, moving the rear bending plate away from the positioning bending roller. The clamping cylinder then fixes the positioning side plate on the bending positioning plate, allowing for the next bending step. Compared to changing equipment or bending rollers, this invention can bend profiles to different radii according to actual needs, improving work efficiency.

[0008] As an improved technical solution, the bending power component includes a bending motor located at the lower part of the mounting plate, and a bending power gear that is poweredly connected to the bending motor is provided at the upper part of the mounting plate. The bending power gear is meshed with the bending driven gear.

[0009] As an improved technical solution, the right side of the positioning side plate is provided with a positioning right plate that is slidably installed on the right side of the bending positioning plate, the right end of the adjusting cylinder is provided with a right fixing plate, the right end face of the right fixing plate is provided with a slide rail arranged back and forth in the axial direction, and the positioning right plate is provided with a slider that cooperates with the slide rail.

[0010] As an improved technical solution, a push plate is fixedly installed on the piston rod of the adjusting cylinder, a slider is provided on the left end face of the push plate, and a slide rail that cooperates with the slider is provided on the left end face of the rear bending plate.

[0011] As an improved technical solution, a protective layer for protecting the profile is provided on the right end face of the rear bending plate, a connecting plate is provided on the left end face of the rear bending plate, the front end face of the connecting plate is flush with the front end face of the rear bending plate, a slider is provided on the front end face of the connecting plate, a slide rail that cooperates with the slider is provided on the rear end face of the positioning side plate, and the distance from the right end face of the slider installed on the connecting plate to the right end face of the connecting plate is not less than the piston rod stroke of the adjusting cylinder.

[0018] 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.

[0019] To facilitate understanding of this patent, the existing profiles are described below. When profiles need to be bent to create edging, existing bending machines use the distance between the centers of the bending rollers as the bending radius. Since multiple bending radii are required for the edging, multiple bending machines are needed to achieve the desired bending and shaping. (Refer to...) Figure 5 As shown, the upper bending radius is much larger than the two lower bending radii. Existing technology uses two bending radii, which increases the purchase cost of the equipment and the floor space required. Processing with two bending radii will affect the processing efficiency.

Figures 1-4 As shown, a bending device applicable to various bending curvatures includes a mounting plate 1, on which a bending mechanism for bending profiles is provided;

[0021] The bending mechanism includes a bending driven gear 501 rotatably mounted on the upper part of the mounting plate 1. The mounting plate 1 is provided with a bending power component that drives the bending driven gear 501 to rotate. The bending power component includes a bending motor 502 located at the lower part of the mounting plate 1. The upper part of the mounting plate 1 is provided with a bending power gear 503 that is poweredly connected to the bending motor 502. The bending power gear 503 meshes with the bending driven gear 501. A bending base plate 504 is fixedly mounted on the upper part of the bending driven gear 501. A positioning bending roller 505, rotatably connected to the bending driven gear 501, is provided on the bending base plate 504. A vertically arranged bending positioning plate 506 is mounted on one end of the bending base plate 504. A clamping cylinder 507 and an adjusting cylinder 508, arranged vertically in the telescopic direction, are sequentially arranged on one side of the bending positioning plate 506 from top to bottom. A positioning side plate 509, which can slide along the length of the bending positioning plate 506, is provided on the front side of the bending positioning plate 506. A reset component 510, which is a reset spring, is provided between the bending positioning plate 506 and the positioning side plate 509. The piston rod of the clamping cylinder 507 is connected to the positioning side plate 509. A fixed spring is slidably mounted on the right side of the bending positioning plate 506. The right positioning plate 511 has a right fixing plate 512 installed at the right end of the adjusting cylinder 508. The right end face of the right fixing plate 512 is provided with a slide rail arranged axially back and forth. The positioning right plate 511 is provided with a slider that cooperates with the slide rail. The left end of the positioning side plate 509 is rotatably mounted with a front bending roller 513 that cooperates with the positioning bending roller 505. The rear side of the positioning side plate 509 is provided with a rear bending plate 514 that can slide left and right on the positioning side plate 509. The right end face of the rear bending plate 514 is slidably connected to the piston rod of the adjusting cylinder 508. A push plate 515 is fixedly installed on the piston rod of the adjusting cylinder 508. The left end face of the push plate 515 is provided with a slider. The left end face of the rear bending plate 514 is provided with a slide rail that cooperates with the slider. The right end face of the rear bending plate 514 is provided with a protective layer for protecting the profile. The left end face of the rear bending plate 514 is provided with a connecting plate 517. The front end face of the connecting plate 517 is flush with the front end face of the rear bending plate 514. A slider is provided on the front end face of the connecting plate 517. A slide rail that cooperates with the slider is provided on the rear end face of the positioning side plate 509. The distance from the right end face of the slider installed on the connecting plate 517 to the right end face of the connecting plate 517 is not less than the piston rod stroke of the adjusting cylinder 508. The distance from the front end face of the rear bending plate 514 to the positioning side plate 509 is not less than the radius of the front bending roller 513. When the piston rod of the adjusting cylinder 508 extends, the distance between the end face of the rear bending plate 514 and the positioning bending roller 505 is less than the distance between the positioning bending roller 505 and the front bending roller 513.

[0022] In use, the present invention employs a material straightening mechanism to correct the profile, a feeding mechanism to convey the profile, a cutting mechanism to cut the profile, and a bending mechanism to bend the profile. When bending a profile with a radius of curvature not greater than that of the front bending roller 513, the clamping cylinder 507 fixes the positioning side plate 509 onto the bending positioning plate 506. Then, the bending power component drives the bending driven gear 501 to rotate, which in turn drives the bending base plate 504 to rotate. The bending base plate 504 rotates due to the rotation belt... The bending positioning plate 506 rotates, which drives the front bending roller 513 to rotate. Since the positioning bending roller 505 is located at the center of the bending driven gear 501, the front bending roller 513 bends the profile around the positioning bending roller 505. When the radius of curvature to be bent is greater than that of the profile bent by the front bending roller 513, the clamping cylinder 507 extends and retracts, allowing the positioning side plate 509 to slide on the bending positioning plate 506. The piston rod of the adjusting cylinder 508 extends, driving the rear bending plate 514 toward the positioning bending roller. The movement at position 505, that is, the rear bending plate 514 slides to the left on the bending positioning plate 506. When the piston rod of the adjusting cylinder 508 extends, the distance between the end face of the rear bending plate 514 and the positioning bending roller 505 is less than the distance between the positioning bending roller 505 and the front bending roller 513. Therefore, the rear bending plate 514 will contact the profile earlier than the front bending roller 513. Since the rear bending plate 514, the positioning side plate 509, and the rear bending plate 514 are all in a state that can slide left and right, as the rear bending plate 51... In the bending of the profile, the friction between the rear bending plate 514 and the profile causes the rear bending plate 514 to move towards the positioning bending roller 505, reducing wear on the left end of the rear bending plate 514 against the profile. After bending, the reset component 510 drives the positioning side plate 509 to reset, and the piston rod of the adjusting cylinder 508 retracts, causing the rear bending plate 514 to move away from the positioning bending roller 505. The clamping cylinder 507 fixes the positioning side plate 509 onto the bending positioning plate 506, thus enabling the next bending process. Compared to changing equipment or bending rollers, this invention can achieve bending of profiles with various radii, allowing for bending of different radii according to actual needs, thus improving work efficiency.

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.
