Description

Technical Field

[0001] The utility model relates to the technical field of cold-bent strip steel production, in particular to a technology for processing the edges of cold-bent strip steel. Background Art

[0002] Cold-formed steel strip is increasingly used in modern industrial production. From structural steel components and color-coated steel sheets in the construction industry to automotive parts and components, and even various supporting structures in machinery manufacturing, cold-formed steel strip plays a key role. As these industries continue to demand higher quality and performance, quality control of cold-formed steel strip has become crucial.

[0003] However, edge quality problems frequently occur during the processing of cold-bent strip steel. For example, during the cold-bending process, the edges of the strip steel are easily squeezed and rubbed by the mold, which can easily produce defects such as burrs and microcracks. These defects not only affect the appearance quality of the strip steel, but more importantly, they can reduce the mechanical properties and performance of the strip steel. In cold-bent steel used in construction, edge burrs may cause injuries to installers and affect splicing accuracy during assembly. In automotive parts, edge microcracks may become the starting point of fatigue fracture, seriously threatening the safety performance of the vehicle.

[0004] The Chinese invention patent with authorization announcement number CN106736961B specifically discloses a strip edging method and equipment suitable for cold-rolled production of thin strip steel. The strip edging equipment disclosed therein is specifically composed of a frame, a width adjustment device, a thickness adjustment device, a grinding device, and a detection and control device that cooperate with each other. It can adapt to strips of various thicknesses and widths. The grinding speed can be adjusted according to the running speed of the strip on the production line to avoid over-grinding and under-grinding of the strip edge. The grinding device has a compensation function to compensate for the wear of the grinding roller, the edge wave of the strip, and the crescent bend of the strip edge during use.

[0005] However, the disclosed strip edge grinding equipment, based on its specific structural design, only uses grinding rollers to remove burrs, resulting in a relatively single function and an inability to adapt to different working conditions, thus affecting the practicality of the entire equipment. Furthermore, the equipment scheme lacks a compression and tensioning structure, which can easily lead to product deformation during the production process, affecting production quality. Summary of the Invention

[0006] In view of the problems existing in the existing cold-bent strip edge processing solutions, the purpose of the present utility model is to provide a cold-bent strip edge processing device that can adapt to various working conditions and at the same time can ensure the quality of the processed products, thereby improving the processing efficiency and quality.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0008] A device for processing the edges of cold-bent strip steel comprises a frame, wherein a winding roller is rotatably mounted on the inner surface of the frame, and a cold-bent strip steel body is provided on the outer surface of the winding roller, and a winding frame is provided on the other end of the cold-bent strip steel body away from the frame, and a deburring mounting frame is provided on both sides of the cold-bent strip steel body, and a slide rail and a mounting seat are fixedly mounted on the deburring mounting frame, and a first bidirectional screw rod is rotatably mounted on the inner surface of the mounting seat, and a transverse moving motor located on the deburring mounting frame is fixedly mounted on the other end of the first bidirectional screw rod away from the mounting seat, and a first fixed plate threadedly connected to the first bidirectional screw rod is slidably connected to the inner surface of the slide rail, and a cutting processing assembly is fixedly mounted on the winding frame, and a deburring processing assembly is fixedly mounted on the other side of the fixed plate away from the deburring mounting frame.

[0009] Preferably, the deburring mounting frame is fixedly installed with a fixing frame at two corners close to the cold-bent strip steel body, and the fixing frame is rotatably installed with a limiting roller on one side close to the cold-bent strip steel body, and the winding frame is fixedly installed with a tensioning roller in contact with the cold-bent strip steel body.

[0010] Through the above technical solution, the limiting roller on the fixed frame is installed at the corner of the deburring mounting frame near the cold-bent strip body, which can limit the lateral position of the cold-bent strip body. During the operation of the cold-bent strip body, it can prevent it from deviating from the normal operation track due to shaking, deviation, etc., ensuring that the cold-bent strip body accurately passes through the deburring processing area, thereby improving the accuracy and stability of the deburring process. The tensioning roller on the winding frame contacts the cold-bent strip body and can apply a certain tension to the cold-bent strip body. This helps to keep the cold-bent strip body taut throughout the entire processing process and avoid slack. During operations such as deburring and trimming, the appropriate tension can make the strip more stable and prevent the processing accuracy from being reduced due to strip slack.

[0011] Preferably, the trimming processing component includes a second fixed plate on the winding frame, and the second fixed plate is provided with a positioning bolt on the other side away from the winding frame, which passes through the second fixed plate and extends to the inside of the winding frame. The second fixed plate is provided with a sliding groove on the other side away from the winding frame, and the second fixed plate is slidably installed with a slide seat through the sliding groove.

[0012] Through the above technical solution, the second fixing plate is connected to the winding frame via a positioning bolt. This connection method not only ensures the second fixing plate is firmly installed on the winding frame, but also facilitates removal and installation adjustment. When parts of the trimming processing assembly need to be repaired or replaced, the second fixing plate can be quickly removed, improving the convenience of equipment maintenance. The design of the slide and slide seat allows the slide to slide flexibly on the second fixing plate, and the trimming position can be precisely adjusted according to the width of the cold-bent strip body and the trimming requirements.

[0013] Preferably, a connecting frame with an L-shaped cross-section is fixedly installed on the other end of the slide away from the second fixed plate, a cylinder is fixedly installed on the side of the connecting frame close to the cold-bent strip steel body, and a cutter is fixedly installed on the output end of the cylinder.

[0014] Through the above technical solution, when trimming operation is required, the cylinder can quickly push the cutter to cut the cold-bent strip steel body, and the cutting force can be controlled by adjusting the air pressure of the cylinder to adapt to cold-bent strip steel bodies of different thicknesses and materials.

[0015] Preferably, two identical trimming processing assemblies are provided, and the two trimming processing assemblies are respectively located on the winding rack and on both sides of the cold-bent strip steel body.

[0016] Through the above technical solution, two identical edge trimming processing components are set on the winding rack and on both sides of the cold-bent strip steel body, so that the edges of both sides of the cold-bent strip steel body can be cut at the same time. The double-sided synchronous processing method can ensure that the edge trimming quality on both sides of the cold-bent strip steel body is consistent, thereby improving production efficiency.

[0017] Preferably, the deburring processing component includes a fixing rod and a reinforcing seat fixedly installed on the other side of the first fixing plate away from the deburring mounting frame, a positioning plate fixedly installed on the other end of the fixing rod away from the deburring mounting frame, a longitudinal moving motor fixedly installed on the other side of the positioning plate away from the fixing rod, a second bidirectional screw rod fixedly installed on the output shaft of the longitudinal moving motor, a burr processing motor is threadedly connected to the outer surface of the second bidirectional screw rod, and a grinding roller is fixedly installed on the output shaft of the burr processing motor.

[0018] Through the above technical solution, the fixing rod on the first fixed plate provides support and structural framework for the entire deburring processing assembly, ensuring the relative position stability of each component, and the positioning plate provides a stable installation base for the longitudinal moving motor, ensuring the position accuracy of the motor during operation.

[0019] Preferably, one side of the reinforcement seat is in contact with the first fixing plate and the other side is in contact with the fixing rod, and the burr processing motor is provided with two identical ones located in the same vertical horizontal direction.

[0020] Through the above technical solution, the fitting design of the reinforcement seat, the first fixed plate and the fixed rod is strengthened, which further enhances the structural strength of the entire deburring processing assembly. The longitudinal moving motor drives the second bidirectional screw to rotate, thereby realizing precise control of the longitudinal position of the burr processing motor. This enables the grinding roller to be flexibly adjusted in the longitudinal direction according to the burr condition of the cold-bent strip body, ensuring that strips of different thicknesses and different burr distributions can be deburred, thereby improving the adaptability of the equipment to different products.

[0021] Compared with the prior art, the processing device for the edge of the cold-bent strip steel has the following beneficial effects:

[0022] 1、The processing device for the edge of the cold-bent strip steel, through the limiting roller on the fixing frame installed at the edge corner of the burr removing mounting frame close to the position of the cold-bent strip steel body and the tension roller on the winding frame in contact with the cold-bent strip steel body, can exert a certain tension on the cold-bent strip steel body. This helps to keep the cold-bent strip steel body in a taut state during the entire processing process, avoiding relaxation, and the appropriate tension can make the strip steel more stable during burr removing and edge cutting operations, prevent the processing precision from being reduced due to strip steel relaxation, and avoid affecting the product production quality.

[0023] 2、The processing device for the edge of the cold-bent strip steel, through the design of the air cylinder, can quickly push the cutter to cut the cold-bent strip steel body, and the cutting force can be controlled by adjusting the air pressure of the air cylinder, adapting to cold-bent strip steel bodies of different thicknesses and materials, and the fitting design of the reinforcing seat, the first fixed plate and the fixed rod further enhances the structural strength of the entire burr removing processing assembly. The longitudinal movement motor drives the second bidirectional screw rod to rotate, realizing accurate control of the longitudinal position of the burr processing motor. This enables the grinding roller to be flexibly adjusted in the longitudinal direction according to the burr condition of the cold-bent strip steel body, ensuring that strip steels of different thicknesses and burr distributions can be burr-removed, improving the adaptability of the equipment to different products, providing multiple processing modes, and improving the diversity of the overall device when in use.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1-5 As shown, it shows an example of the composition structure of the processing device for the edge of the cold-bent strip in this example.

[0035] Based on the diagram, the device for processing the edge of the cold-bent strip steel mainly comprises a frame 1, a winding roller 2 is rotatably installed on the inner surface of the frame 1, a cold-bent strip steel body 3 is provided on the outer surface of the winding roller 2, a winding frame 4 is provided at the other end of the cold-bent strip steel body 3 away from the frame 1, and deburring mounting frames 5 are provided on both sides of the cold-bent strip steel body 3.

[0036] The deburring mounting frame 5 is fixedly mounted with a slide rail 6 and a mounting seat 7, and a first bidirectional screw rod 8 is rotatably mounted on the inner surface of the mounting seat 7; the other end of the first bidirectional screw rod 8 away from the mounting seat 7 is fixedly mounted with a transverse moving motor 9 located on the deburring mounting frame 5.

[0037] Furthermore, a first fixed plate 10 threadedly connected to the first bidirectional screw 8 is slidably connected to the inner surface of the slide rail 6, a trimming processing component 14 is fixedly installed on the winding frame 4, and a deburring processing component 15 is fixedly installed on the other side of the fixed plate away from the deburring mounting frame 5.

[0038] The following describes the specific implementation of the device for processing the edge of the bent strip steel in this example.

[0039] Combine Figures 1 to 4 The deburring mounting frame 5 in this processing device is fixedly installed with a fixing frame 11 near the two corners of the cold-bent strip steel body 3. The fixing frame 11 is rotatably installed with a limiting roller 12 on one side close to the cold-bent strip steel body 3, and a tensioning roller 13 in contact with the cold-bent strip steel body 3 is fixedly installed on the winding frame 4.

[0040] With such an arrangement, the limiting roller 12 on the fixing frame 11 is installed at a position close to the cold-bent steel strip body 3 at the corner of the deburring mounting frame 5, so as to limit the lateral position of the cold-bent steel strip body 3. During the operation of the cold-bent steel strip body 3, it can prevent it from deviating from the normal operation track due to shaking, offset, etc., thereby ensuring that the cold-bent steel strip body 3 accurately passes through the deburring processing area, thereby improving the accuracy and stability of the deburring processing.

[0041] Furthermore, the tensioning roller 13 on the winding frame 4 is in contact with the cold-bent steel strip body 3, which can apply a certain tension to the cold-bent steel strip body 3. This helps to keep the cold-bent steel strip body 3 taut throughout the entire processing process and avoid slack. During operations such as deburring and trimming, the appropriate tension can make the strip more stable and prevent the processing accuracy from being reduced due to strip slack.

[0042] Further integration Figure 6 As shown, the edge trimming processing component 14 in this device specifically includes a second fixed plate 1401 on the winding frame 4, and a positioning bolt 1402 is provided on the other side of the second fixed plate 1401 away from the winding frame 4, which passes through the second fixed plate 1401 and extends to the inside of the winding frame 4. A sliding groove 1403 is provided on the other side of the second fixed plate 1401 away from the winding frame 4, and the second fixed plate 1401 is slidably installed with a slide seat 1404 through the sliding groove 1403.

[0043] In this arrangement, the second fixing plate 1401 of the trimming assembly 14 is connected to the winding frame 4 via a positioning bolt 1402. This connection ensures a secure mounting of the second fixing plate 1401 on the winding frame 4 while facilitating removal, installation, and adjustment. When parts of the trimming assembly 14 need repairing or replacing, the second fixing plate 1401 can be quickly removed, improving maintenance convenience.

[0044] Meanwhile, based on the matching scheme of the set sliding groove 1403 and sliding seat 1404, the sliding seat 1404 can slide on the second fixed plate 1401 flexibly, and the cutting edge position can be accurately adjusted according to the width of the cold-bent strip body 3 and the cutting edge requirement.

[0045] Further, the sliding seat 1404 in the cutting edge processing assembly 14 is fixedly installed with a connecting frame 1405 in an "L" shape structure at the other end away from the second fixed plate 1401, a pneumatic cylinder 1406 is fixedly installed on the side of the connecting frame 1405 close to the cold-bent strip body 3, and a cutting knife 1407 is fixedly installed on the output end of the pneumatic cylinder 1406. In this way, when the cutting edge operation is needed, the pneumatic cylinder 1406 can quickly push the cutting knife 1407 to cut the cold-bent strip body 3, and the cutting force can be controlled by adjusting the air pressure of the pneumatic cylinder 1406 to adapt to cold-bent strip bodies 3 of different thicknesses and materials.

[0046] Embodiment two:

[0047] Based on the scheme of embodiment one, this example further gives a specific optimization scheme.

[0048] In combination Figures 1 to 3 , based on the scheme of embodiment one, two same cutting edge processing assemblies 14 are arranged on the winding frame 4 and on both sides of the cold-bent strip body 3. The same two cutting edge processing assemblies 14 arranged on the winding frame 4 and on both sides of the cold-bent strip body 3 in this example can simultaneously cut the two side edges of the cold-bent strip body 3, and the double-side synchronous processing mode can ensure that the cutting edge quality of the two sides of the cold-bent strip body 3 is consistent, thereby improving the production efficiency.

[0049] Further, referring to Figure 7 , a specific structure scheme of the deburring processing assembly 15 is given in this example.

[0050] Based on the drawings, the deburring processing assembly 15 given in this example includes a fixed rod 1501 and a reinforcing seat 1502 fixedly installed on the other side of the first fixed plate 10 away from the deburring mounting frame 5, the fixed rod 1501 is fixedly installed with a positioning plate 1503 at the other end away from the deburring mounting frame 5, the positioning plate 1503 is fixedly installed with a longitudinal movement motor 1504 on the other side away from the fixed rod 1501, a second bidirectional screw rod 1505 is fixedly installed on the output shaft of the longitudinal movement motor 1504, a burr processing motor 1506 is threadedly connected to the outer surface of the second bidirectional screw rod 1505, and a grinding roller 1507 is fixedly installed on the output shaft of the burr processing motor 1506.

[0051] The fixed rod 1501 on the first fixed plate 10 provides support and structural framework for the entire deburring assembly 15, ensuring the relative position of each component is stable. The positioning plate 1503 provides a stable mounting base for the longitudinal movement motor 1504, ensuring the position accuracy of the motor during operation.

[0052] Further, one side of the reinforcing seat 1502 in the deburring assembly 15 is attached to the first fixed plate 10, and the other side is attached to the fixed rod 1501. The deburring motor 1506 is provided with two identical motors in the same vertical direction. With this arrangement, the attachment of the reinforcing seat 1502 to the first fixed plate 10 and the fixed rod 1501 further enhances the structural strength of the entire deburring assembly 15. The longitudinal movement motor 1504 drives the second bidirectional screw rod 1505 to rotate, achieving precise control of the longitudinal position of the deburring motor 1506. This allows the grinding roller 1507 to adjust flexibly in the longitudinal direction according to the edge condition of the cold-bent strip body 3, ensuring that strips of different thicknesses and edge distributions can be deburred, improving the adaptability of the equipment to different products.

[0053] For the above-mentioned cold-bent strip edge processing device, the following example illustrates the working process.

[0054] In combination Figures 1 to 7 , when the cold-bent strip edge processing device is in use, the limiting roller 12 on the fixed frame 11 is installed at the corner of the deburring mounting frame 5 near the cold-bent strip body 3, which can limit the transverse position of the cold-bent strip body 3. During the operation of the cold-bent strip body 3, it can prevent it from deviating from the normal running track due to shaking, deviation, etc., ensuring that the cold-bent strip body 3 accurately passes through the deburring processing area, thereby improving the accuracy and stability of the deburring process. The tensioning roller 13 on the winding frame 4 is in contact with the cold-bent strip body 3, which can apply a certain tension to the cold-bent strip body 3. This helps to maintain the cold-bent strip body 3 in a taut state during the entire processing process, avoiding relaxation. During deburring and edge cutting operations, appropriate tension can make the strip more stable, preventing the processing accuracy from being reduced due to strip relaxation.

[0055] On this basis, the second fixed plate 1401 is connected with the winding frame 4 through the positioning bolt 1402, which not only ensures the stable installation of the second fixed plate 1401 on the winding frame 4, but also facilitates disassembly and installation adjustment. When it is necessary to maintain or replace part of the components of the trimming processing assembly 14, the second fixed plate 1401 can be quickly disassembled, thereby improving the convenience of equipment maintenance. The design of the sliding groove 1403 and the sliding seat 1404 enables the sliding seat 1404 to flexibly slide on the second fixed plate 1401, so that the trimming position can be accurately adjusted according to the width of the cold-bent strip body 3 and the trimming requirement. When it is necessary to perform trimming operation, the cylinder 1406 can quickly push the cutter 1407 to cut the cold-bent strip body 3, and the cutting force can be controlled by adjusting the air pressure of the cylinder 1406, so as to adapt to cold-bent strip bodies 3 of different thicknesses and materials. The same two trimming processing assemblies 14 are arranged on the winding frame 4 and on both sides of the cold-bent strip body 3, so that the two side edges of the cold-bent strip body 3 can be simultaneously cut and processed. The double-side synchronous processing mode can ensure that the trimming quality of the two sides of the cold-bent strip body 3 is consistent, thereby improving the production efficiency.

[0056] On this basis, the fixed rod 1501 on the first fixed plate 10 provides support and a structural framework for the entire deburring processing assembly 15, so as to ensure the relative position stability of the components. The positioning plate 1503 provides a stable installation basis for the longitudinal movement motor 1504, so as to ensure the position accuracy of the motor during operation. The close-fit design of the reinforcing seat 1502 with the first fixed plate 10 and the fixed rod 1501 further enhances the structural strength of the entire deburring processing assembly 15. The longitudinal movement motor 1504 rotates the second bidirectional screw rod 1505 through driving, so as to realize the accurate longitudinal position control of the burr processing motor 1506. This enables the grinding roller 1507 to be flexibly adjusted in the longitudinal direction according to the burr condition of the cold-bent strip body 3, so as to ensure that the deburring processing can be performed on strip steels of different thicknesses and different burr distributions, thereby improving the adaptability of the equipment to different products.

[0057] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
