Description

Technical Field

[0001] The present invention belongs to the technical field of C-shaped steel processing, and specifically relates to a continuous and efficient punching device for the groove surface of C-shaped steel. Background Art

[0002] C-shaped steel is a thin-walled steel section manufactured by a cold bending forming process. During processing, it continuously discharges materials, and then is cut according to requirements. Its cross-section is in the shape of the English letter "C", with an open groove structure. Due to its lightweight, high strength, and easy installation characteristics, it is widely used in fields such as construction, machinery, and transportation. Its structure consists of a middle web and flanges that perpendicularly extend from both sides of the web. The web mainly bears shear forces and loads, and the flanges increase the overall bending resistance. Usually, the ends of the flanges are provided with curled edges to improve local stability and the anti-deformation ability at the ends of the flanges. The area composed of the web and the two side flanges of the C-shaped steel is the "groove surface" or working surface, which is used to install and fix components such as bolts.

[0003] When producing C-shaped steel, it is usually necessary to punch holes in the groove surface of the C-shaped steel according to actual usage requirements. The punching positions may be on the web or on the flange according to different requirements. When punching, punching processing or drilling processing is usually used. Punching processing has the advantage of fast punching speed and is suitable for processing continuous and uniform hole patterns, while drilling processing has the advantage of good flexibility and is suitable for punching when the hole pitch is uneven.

[0004] Existing punching equipment, such as a C-shaped steel punching device with the publication number CN219503760U. This C-shaped steel punching device includes a mounting frame, an adjustment component, and a uniform speed component. A driving device is arranged on the mounting frame, and a drilling device is arranged at the bottom of the driving device. The adjustment component is located inside the mounting frame and can be used to adjust the position of the C-shaped steel. The uniform speed component is located below the adjustment component and includes a first mounting rod, a toothless gear, a second mounting rod, a gear, a cam, and a motor. The motor can drive the toothless gear to rotate, and the toothless gear can drive the cam to rotate. The uniform speed component can be used to drive the C-shaped steel to perform intermittent punching work.

[0005] It punches the C-shaped steel after cutting and truncating, and cannot punch the C-shaped steel during the continuous production process, which wastes a lot of time and affects production efficiency.

[0006] Moreover, when punching the C-shaped steel, especially when punching the flange, it is difficult to obtain effective and stable support inside the C shape. Then, when punching, the flange of the thin-walled C-shaped steel is easily compressed and deformed, changing its cross-sectional shape and affecting product quality.

[0007] The Chinese patent with the publication number CN114871785B discloses a continuous C-shaped steel punching and cutting production line, which successively includes a forming roll group, a stamping device and a cutting device along the direction of the steel material advancing. The forming roll group includes a forming seat, and a number of rolling rolls are rotatably connected to the forming seat. The stamping device includes a processing table, and a stamping die is provided on the processing table. The profiled steel passes through the stamping die, and a structural groove is formed on the profiled steel. It also includes an accompanying track. The stamping device further includes a first driving component. The accompanying track is fixedly connected to the forming seat, and the processing table is slidably connected to the accompanying track. The first driving component is used to control the movement of the processing table. When the stamping die punches the profiled steel, the processing table and the stamping die are synchronously moved with the profiled steel through the first driving component, so that the profiled steel continuously advances and works on the production line to realize the function of synchronous punching during the continuous production process, thereby improving the production efficiency.

[0008] However, the above patent still has the following disadvantages:

[0009] 1. Since the C-shaped steel material is relatively thin, when punching, it is easy to cause defects such as depressions around the holes, which affects the product quality. At the same time, when installing connecting components such as bolts later, the depressions around the holes are not convenient for installation, and the depressions will cause gaps between the nut or gasket and the C-shaped steel groove surface, which is not conducive to stable connection.

[0010] 2. Since the processing and production of C-shaped steel is continuous, the continuous punching device described in the above patent also needs to work continuously for a long time. During the long-term working process, components such as the driving parts of the device will inevitably have errors. If the errors cannot be corrected and calibrated in time, it is easy to cause the continuous accumulation of errors, and then lead to large deviations in the positions of subsequent punching processes, affecting the processing quality. Summary of the Invention

[0011] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to enable the frame to move along the conveying direction of the C-shaped steel, so that after continuous cold bending processing of the C-shaped steel, the frame and the C-shaped steel move at the same speed and at the same time use a drilling machine for drilling processing, and after the processing is completed, the frame is reset to facilitate subsequent drilling processing again, so as to achieve efficient and continuous punching work on the C-shaped steel, improve the processing and production efficiency. By setting up an inner support component, the inner support component is used to support at the drilling position, effectively avoiding the problem that the pressure exerted by the drilling machine on the flange part of the C-shaped steel during drilling causes the flange to bend, and then causing the cross-sectional shape of the C-shaped steel to change and affecting the finished product quality. By setting up a shaftless pressure roller and an outer pressure roller, the surface of the C-shaped steel after punching can be rolled and leveled during the process of the frame resetting and returning after the drilling machine finishes drilling, so as to eliminate the depression around the hole after the drilling machine drills, thus ensuring the final finished product quality of the C-shaped steel and avoiding the holes with depressions from affecting the subsequent use of the C-shaped steel. By setting up a visual detector, it can detect whether the punching position is accurate after punching, or whether there is a problem of hole shape deformation caused by the different conveying speeds of the frame and the C-shaped steel, and then timely feedback to the control system, and the control system quickly responds to adjust and calibrate the first linear module and the second linear module, so as to achieve real-time correction of the drilling processing and ensure that the device can still ensure good processing quality and processing effect under long-term continuous work.

Detailed implementation manners

[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] As Figures 1-8 shown, a continuous and efficient punching device for the groove surface of C-shaped steel includes a C-shaped steel 10 and a frame 11. The C-shaped steel 10 passes through the inside of the frame 11. An inner support member is fixedly connected to the top of the C-shaped steel 10. The inner support member extends into the inner side of the C-shaped steel 10 and fits and rolls with the inner surface of the C-shaped steel 10. Three first linear modules 22 are respectively fixedly connected to the frame 11 at the positions of the web and the two flange edges of the C-shaped steel 10. The driving end of each first linear module 22 is fixedly connected to a second linear module 23. A second linear module 23 perpendicular to the first linear module 22 is drivingly connected to each second linear module 23. Each second linear module 23 is drivingly connected to a drilling machine 24. The drill bit of each drilling machine 24 points to the surface of the C-shaped steel 10. The frame 11 can reciprocate along the conveying direction of the C-shaped steel 10.

[0042] By setting that the frame 11 can move along the conveying direction of the C-shaped steel 10, after continuous cold bending processing of the C-shaped steel 10, the frame 11 is made to move at the same speed as the C-shaped steel 10 and at the same time the drilling machine 24 is used for drilling processing, and after the processing is completed, the frame 11 is reset to facilitate subsequent drilling processing again, so as to realize the efficient and continuous punching work of the C-shaped steel 10 and improve the processing and production efficiency.

[0043] And by setting the inner support member, the inner support member is used for supporting at the drilling position, effectively avoiding the problem that the pressure exerted by the drilling machine 24 on the flange part of the C-shaped steel 10 during drilling causes the flange to bend, and then causing the cross-sectional shape of the C-shaped steel 10 to change and affecting the finished product quality.

[0044] Moreover, by setting the first linear module 22 and the second linear module 23, the punching position can be conveniently adjusted, thereby meeting different processing requirements and being more flexible and convenient to use.

[0045] As Figures 1-8 shown, two slide rails 27 are respectively arranged on the bottom side of the frame 11. A set of sliders 30 are slidably connected in each slide rail 27. Each set of sliders 30 is fixedly connected to the frame 11. A lead screw 28 is rotatably connected in each slide rail 27. Each set of sliders 30 is threadedly connected to the corresponding lead screw 28. One end of each slide rail 27 is fixedly connected to a motor 29. The power output end of each motor 29 is drivingly connected to the corresponding lead screw 28. A length measuring wheel 31 is fixedly connected to the frame 11 at a position on one side of the C-shaped steel 10. The length measuring wheel 31 is in rolling contact with the surface of the C-shaped steel 10.

[0046] By setting the lead screw 28 and the slider 30, the function of driving the frame 11 to move along the conveying direction of the C-shaped steel 10 can be realized. And by setting the length measuring wheel 31, the control system can accurately know the conveying length and moving speed of the C-shaped steel 10, so as to control the moving speed of the frame 11 to be consistent with the conveying speed of the C-shaped steel 10, thereby ensuring the stability and accuracy of the drilling process.

[0047] As Figures 1-8 shown, the inner support member includes a top plate 12. The top plate 12 is fixedly connected to the top of the C-shaped steel 10. At both ends of the bottom side of the top plate 12, a first side plate 13, a second side plate 14 and a third side plate 15 are fixedly connected in sequence from outside to inside. A gap convenient for the operation of the drill 24 is left between the two third side plates 15. Two push roller seats 16 are slidably connected in the horizontal direction between each first side plate 13 and the second side plate 14. One push roller seat 16 is slidably connected in the vertical direction between each second side plate 14 and the third side plate 15. A set of push rollers 17 are rotatably connected to the end of each push roller seat 16. A shaftless pressure roller 18 is rotatably arranged on the outside of each set of push rollers 17. The contour shape of the shaftless pressure roller 18 is consistent with the inner dimension shape of the C-shaped steel 10. The shaftless pressure roller 18 is in rolling contact with the inner wall of the C-shaped steel 10. A set of pressure roller seats 25 are fixedly connected to the frame 11 at positions corresponding to the shaftless pressure rollers 18. An external pressure roller 26 is rotatably connected in each set of external pressure rollers 26. Each external pressure roller 26 is in rolling contact with the outer surface of the C-shaped steel 10.

[0048] By setting the shaftless pressure roller 18 and the external pressure roller 26, it is possible to roll and flatten the surface after punching of the C-shaped steel 10 during the process of the frame 11 resetting and returning after the drilling operation of the drill 24 is completed, thereby eliminating the depression that appears around the hole after the drill 24 drills the hole, ensuring the final product quality of the C-shaped steel 10, and avoiding the influence of the hole with depression on the subsequent use of the C-shaped steel 10. The use of the shaftless pressure roller 18 can more comprehensively fit the inner surface of the C-shaped steel 10, thus providing a more comprehensive rolling and flattening effect, and it is more convenient to replace the shaftless pressure roller 18 after it is worn.

[0049] As Figures 1-8 shown, a bidirectional screw 21 is rotatably connected between two first side plates 13. The two ends of the bidirectional screw 21 have the same pitch and opposite screw directions. Two wedge blocks 20 are respectively threadedly connected to the two ends of the bidirectional screw 21. Each wedge block 20 can fit and slide on the inclined surface of the adjacent roller seat 16. The first side plate 13, the second side plate 14 and the third side plate 15 on the same side are fixedly connected by fastening bolts 19.

[0050] By setting the wedge block 20 and the bidirectional screw 21, it is possible to make each shaftless pressure roller 18 closely fit the inner surface of the C-shaped steel 10 by screwing the bidirectional screw 21, avoiding the existence of gaps that affect the rolling and flattening effect. At the same time, the pressure of each shaftless pressure roller 18 on the inner side of the C-shaped steel 10 can be adjusted, so that the shaftless pressure roller 18 and the external pressure roller 26 can effectively roll and flatten the depression around the hole, ensuring the flattening effect.

[0051] As Figures 1-8 shown, a bracket 32 is arranged behind the frame 11 along the conveying direction of the C-shaped steel 10. Visual detectors 33 are respectively fixedly connected to both sides and the top of the bracket 32. Each visual detector 33 points to the outer surface of the C-shaped steel 10. Inclined parts are respectively arranged at both ends of the top of the bracket 32. Light sources 34 are fixedly connected to the inclined parts at the top of the bracket 32. The light emitting area of each light source 34 points to the C-shaped steel 10. Two groups of idler rollers 35 are fixedly connected to the bracket 32. Each group of idler rollers 35 rolls in contact with the bottom edge of the C-shaped steel 10.

[0052] By setting the visual detector 33, it is possible to detect whether the punching position is accurate after punching, or whether there is a problem of hole shape deformation caused by the different conveying speeds of the frame 11 and the C-shaped steel 10, and then feed it back to the control system in time. The control system quickly responds to adjust and calibrate the first linear module 22 and the second linear module 23, so as to realize real-time correction of the drilling process and ensure that the device can still ensure good processing quality and processing effect under long-term continuous operation.

[0053] Meanwhile, by setting the light source 34, brighter light can be provided, which facilitates clearer imaging by the vision detector 33, ensuring the accuracy of detection by the vision detector 33. By setting the idler roller 35, the C-shaped steel 10 can be guided and stabilized, preventing the C-shaped steel 10 from shaking during transportation and affecting the detection accuracy of the vision detector 33.

[0054] In this embodiment, the device is arranged behind the cold bending processing equipment of the C-shaped steel 10. After the C-shaped steel 10 undergoes cold bending, the operator first passes the end of the C-shaped steel 10 through between the frame 11 and the support 32 in sequence, and finally inserts it into the cutting device arranged behind this device. When the C-shaped steel 10 passes through the frame 11, ensure that the inner support member passes through the inside of the C-shaped steel 10. Since the shaftless pressure roller 18 is always in contact with the inner wall of the C-shaped steel 10 and rolls under the support of the pushing roller 17 during the continuous production of the C-shaped steel 10, the shaftless pressure roller 18 will not fall off even without the positioning and restriction of the rotating shaft, and the shaftless pressure roller 18 can always roll and work inside the C-shaped steel 10.

[0055] Before the drilling operation, the operator first uses tools such as a wrench to screw the end of the bidirectional screw 21, causing the two wedge-shaped blocks 20 to move towards each other. During the movement of the wedge-shaped blocks 20, they slide by squeezing against the inclined surfaces of the push roller seats 16, respectively pushing the corresponding two-point push roller seats 16 to move horizontally or vertically, so that the push roller 17 pushes the shaftless pressure roller 18 to make the shaftless pressure roller 18 closely fit the inner wall of the C-shaped steel 10 to avoid gaps. At the same time, adjust the length measuring wheel 31 to make it closely fit the surface of the C-shaped steel 10.

[0056] During the drilling operation, this device is connected to the power supply and the control system. After cold bending, the steel raw material is continuously transported and moved. At this time, the frame 11 does not move, and the shaftless pressure roller 18 and the external pressure roller 26 roll on the inner and outer surfaces of the C-shaped steel 10. The length measuring wheel 31 rolls and records information such as the conveying distance and conveying speed of the C-shaped steel 10, and transmits the information to the control system. When the control system determines that the designated drilling position is reached, the control system starts the motor 29 to drive the lead screw 28 to rotate. Through the threaded connection between the lead screw 28 and the slider 30, the slider 30 and the C-shaped steel 10 are driven to move along the conveying direction of the C-shaped steel 10, and it is ensured that the moving speeds of the frame 11 and the C-shaped steel 10 are the same, so that the frame 11 and the C-shaped steel 10 remain relatively stationary.

[0057] During the synchronous movement of the frame 11 and the C-shaped steel 10, the control system starts the high-speed rotation of the drilling rig 24, and starts the second linear module 23 to make the drilling rig 24 quickly move towards the C-shaped steel 10 to drill the groove surface of the C-shaped steel 10. After the hole is drilled through, the control system controls the second linear module 23 to move in the reverse direction to reset the drilling rig 24. By controlling the first linear module 22, the drilling position of the drilling rig 24 can be adjusted, or multiple holes can be processed in sequence at the same cross-section position of the C-shaped steel 10. During the drilling process, the control system can control the frame 11 to stop moving for a short time and then drive the frame 11 and the C-shaped steel 10 to move synchronously again, so that the processing position of the drilling rig 24 changes slightly in the conveying direction of the C-shaped steel 10, realizing the adjustment of the drilling position along the conveying direction of the C-shaped steel 10.

[0058] After the drilling process is completed, depressions are likely to appear around the hole. At this time, the control system controls the motor 29 to reverse, thereby driving the frame 11 to return to the initial position for reset. During the reset process of the frame 11, the shaftless roller 18 and the external roller 26 cooperate to roll and press on the inner and outer surfaces of the C-shaped steel 10, so as to roll and flatten the depressions around the hole, thereby ensuring the processing quality of the C-shaped steel 10. During the rolling process of the shaftless roller 18, the pushing roller 17 provides pressure, and the pushing roller 17 and the shaftless roller 18 roll relative to each other, reducing the friction force so that the shaftless roller 18 can roll smoothly inside the C-shaped steel 10.

[0059] During the continuous drilling process, the visual detector 33 continuously detects the formed holes, detects whether the drilling position is accurate, or whether there is hole deformation caused by the different moving speeds of the C-shaped steel 10 and the frame 11. The visual detector 33 transmits the detected information data to the control system, and the control system judges and corrects and calibrates the driving and detecting components of the first linear module 22, the motor 29, and the length measuring wheel 31 to ensure that the subsequent drilling process can be carried out stably and accurately, and ensure the processing quality of the C-shaped steel 10.

[0060] After the C-shaped steel 10 is processed by punching and detected by the visual detector 33, the C-shaped steel 10 is conveyed to the cutting device, and the cutting device cuts the C-shaped steel 10 at an appropriate position to finally form the finished C-shaped steel 10.

[0061] The above-mentioned first linear module 22, second linear module 23, drilling rig 24, motor 29, length measuring wheel 31, visual detector 33, etc. are mature existing technologies, and the structures in the drawings are only for illustration and will not be elaborated herein.
