Description

Technical Field

[0001] This invention belongs to the field of angle steel bracket processing technology, specifically involving drilling and bending equipment for angle steel brackets. Background Technology

[0002] As the name suggests, angle steel brackets are brackets made of angle steel. Because the two sides of an angle steel bracket are perpendicular to each other, it has strong stability and load-bearing capacity, and is therefore widely used in construction, machinery, furniture and other fields. It is mainly used to support and fix various components to ensure their stability and safety. Drilling holes in angle steel brackets is a key step in their processing and installation. The core purpose is to achieve connection and fixation, position adjustment and functional adaptation. After drilling, fasteners such as bolts, screws and rivets can be passed through the holes to rigidly connect different components. Compared with welding or binding, drilling connection has obvious advantages. At the same time, in order to ensure the stability of the bracket, the angle steel needs to be bent into a more supportive right angle. The right angle of the angle steel is essentially an L-shaped cross-section structure. This shape can efficiently distribute external forces to two perpendicular sides, thereby avoiding the concentration of load in a single part. Moreover, in industrial building scenarios, most of the structures that require brackets have right-angle interfaces. The right-angle shape of the angle steel can directly match these scenarios without additional processing to adapt the angle, greatly simplifying the installation.

[0003] After drilling holes in angle steel, uneven local stress can cause issues such as hole wall protrusions and slight hole edge protrusions on the surface of the angle steel. Although most of these protrusions are slight, these minor deformations can still compromise the dimensional accuracy of the original design, leading to deviations during installation or even preventing proper assembly. While slight deformations may not seem to affect the appearance, they can alter the stress structure of the angle steel, causing localized stress concentrations and reducing the overall load-bearing capacity. This poses a significant risk, especially in heavy-duty applications. Furthermore, it can shorten the lifespan of the angle steel components and increase subsequent maintenance costs. Therefore, workers need to carefully inspect the angle steel after drilling. Manual inspection is inefficient and may miss protrusions, resulting in poor quality of the finished product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a drilling and bending processing equipment for angle steel brackets.

[0005] The technical solution adopted to solve the above technical problems is: An angle steel bracket drilling and bending processing equipment includes a processing table, which includes a punching machine, a frame and a bending machine. The frame is fixedly installed on one side of the punching machine and the bending machine is installed on one side of the frame. Several support bars are provided in the frame. Two clamps are fixedly installed on the support bar, and both clamps are located on the same support bar. Each clamp has a vertical plate on both sides of its side wall, and the side wall of the vertical plate has an arc-shaped groove. A dual-axis motor is also installed on the side wall of the support bar, and each of the two output ends of the dual-axis motor is equipped with a tightening mechanism for controlling the tightness of the clamps. Several detection rollers are also provided on the support bar between the clamp and the punching machine. Two sets of telescopic rods are fixedly provided on the frame. A limiting groove is fixedly provided on the top of the telescopic rod. The detection roller slides in the limiting groove. A top plate is fixedly provided on the side wall of the upright plate. Several movement grooves are opened on the side wall of the top plate. The positions of the several movement grooves correspond one-to-one with the positions of the several detection rollers. An electric push rod is also fixedly provided on the side wall of the top plate. A push plate is fixedly connected to the output end of the electric push rod.

[0006] The above technical solution involves setting up clamps and a clamping mechanism on the stand to clamp and fix the angle steel when the punching machine drills holes in it, thereby ensuring the drilling quality. After drilling, the surface of the angle steel can be inspected using a testing roller, and a marker pen can be used to mark the protruding positions, making it convenient for workers to correct the position.

[0007] Furthermore, a guide platform is installed on the side wall of the punching machine facing away from the stand, and a guide slope is also provided at the end of the guide platform away from the punching machine.

[0008] With the above technical solution, the workers can insert the angle steel to be processed from the guide table into the punching machine, and the guide table can limit the angle steel. This not only makes the process of pushing the angle steel into the punching machine smoother, but also ensures that the position of the angle steel will not shift, thereby ensuring that the punching position will not be wrong.

[0009] Furthermore, the clamp includes a drive rod, a fixed base, a top block, a swing rod, an inner rod, a stop block, an extension rod, and a fixed pad. The drive rod is fixedly mounted on the side wall of the top block, and its two ends are slidably connected to the inner walls of two opposing arc-shaped grooves. The swing rod is fixedly connected to the bottom of the top block, and its other end is rotatably connected to the side wall of the fixed base. The fixed base is fixedly mounted on the top of the support bar. One end of the extension rod is rotatably connected to the top of the fixed base, and its other end is fixedly connected to the side wall of the fixed pad. The fixed pad abuts against the top of the support bar. One end of the inner rod is rotatably connected to the inner wall of the swing rod, and its other end is rotatably connected to the side wall of the extension rod. The stop block is fixedly mounted on the side wall of the inner rod, and its side wall abuts against the side wall of the extension rod.

[0010] With the above technical solution, the drive rod moving in the arc groove will drive the top block to move. The top block set at the top of the swing rod will drive the swing rod to move together. When the swing rod rotates around the fixed seat, the internal rod set inside the swing rod will drive the stop block to leave the position of the extension rod, thereby causing the fixed pad to leave the position of the support bar. This makes it convenient for the operator to push the angle steel into the original position of the fixed pad. After the drive rod returns to the initial position, the fixed pad will return to the original position, thereby fixing the angle steel in the current position, which is convenient for the punching machine to drill holes in the angle steel.

[0011] Furthermore, the fixing pad is made of rubber, and the height of the lowest point of the fixing pad is the same as the height of the fixing base.

[0012] With the above technical solution, since the fixing pad needs to be driven back to the initial position by the drive rod, and the original position is occupied by the angle steel pushed in by the staff, the fixing pad needs to be made of deformable rubber material, which can not only meet the needs of clamping the angle steel, but also avoid damaging the surface of the angle steel.

[0013] Furthermore, the tensioning mechanism includes an extension rod, a worm gear, a worm wheel, and a swing plate. The extension rod is fixedly mounted on the output end of the dual-axis motor. The worm gear is fixedly mounted on the side wall of the extension rod away from the dual-axis motor. A central rod is rotatably connected between the two support rods. The worm wheel is fixedly mounted on the central rod, and the worm gear meshes with the worm wheel. The swing plate is fixedly mounted on the side wall of the central rod, and the other end of the swing plate is fixedly connected to the side wall of the drive rod.

[0014] With the above technical solution, the two output ends of the dual-axis motor will rotate in the same direction, and the dual-axis motor can be driven to rotate in both directions. Therefore, the dual-axis motor will drive the extension rod and the worm to rotate, and the worm wheel meshing with the worm will drive the swing plate to swing, thereby causing the drive rod to move in the arc groove, so that the clamp is driven to clamp the angle steel.

[0015] Furthermore, the detection roller includes a vertical rod, a sliding rod, a lifting plate, a roller, a first spring, a second spring, a sleeve, and a marker. The vertical rod is located inside the lifting plate, the bottom of the lifting plate is rotatably connected to the roller, the top of the vertical rod is fixedly connected to the bottom of the push plate, a motion hole is opened on the side wall of the lifting plate, the sliding rod passes through the motion hole, and both ends of the sliding rod are slidably connected to the inner walls of two limiting grooves respectively. One end of the first spring abuts against the bottom of the sliding rod, a sliding groove is opened at the bottom of the motion hole, and the other end of the first spring is slidably connected to the inner wall of the sliding groove. The second spring is fixed to the side wall of the first spring, and the other end of the second spring passes through the side wall of the motion hole and is rotatably connected to the side wall of the sleeve. The marker is movably disposed inside the sleeve, and one end of the sleeve is rotatably connected to the side wall of the lifting plate.

[0016] Through the above technical solution, the setting of the first spring piece ensures that the sliding rod is at the top of the moving hole. At this time, the roller will contact the surface of the angle steel. If it encounters a protrusion on the surface of the angle steel, the protrusion will push the roller upward. Therefore, the lifting plate will be driven upward by the roller, thereby compressing the first spring piece. The bottom of the first spring piece slides in the sliding groove, thereby driving the second spring piece to move away from the sleeve. The rotating sleeve drives the marker pen to rotate together, thereby marking the position of the protrusion, which is convenient for the staff to correct later. Furthermore, since the movable part of the marker pen is located inside the sleeve, it can be easily removed and replaced when the marker pen cannot mark the position. The movable part here includes, but is not limited to, threaded connection, magnetic connection, or adhesive connection.

[0017] Furthermore, the upright is fixedly mounted on the top of the sliding rod, and the lifting plate has a movable hole inside, through which the upright extends.

[0018] With the above technical solution, the two ends of the upright are respectively set at the bottom of the push plate and the top of the sliding rod. Both of these components are fixed. The only movable part is the lifting plate with rollers at the bottom. When it encounters a protrusion on the surface of the angle steel, the rollers will drive the lifting plate to rise, ensuring that the upright can rise in the correct direction.

[0019] Furthermore, the first spring is Z-shaped, with its top fixedly connected to the bottom of the sliding rod and its bottom slidably connected to the inner wall of the groove.

[0020] With the above technical solution, when the lifting plate rises, the first spring is compressed. The "Z"-shaped design causes the bottom of the first spring to slide in the groove, which in turn causes the first spring to drive the second spring to move laterally together, which in turn causes the sleeve to drive the marker pen to mark the protruding position.

[0021] Furthermore, the height of the marker tip is greater than the height of the bottom of the roller, and the height of the roller is the same as the height of the punching machine.

[0022] With the above technical solution, in the initial case, the tilted marker will not contact the surface of the angle steel. Therefore, the height of the marker needs to be relatively high, but not too high. This is because when the second spring causes the sleeve and the marker to rotate together, the marker needs to mark the surface of the angle steel as soon as possible. Therefore, the height difference between the two needs to be small.

[0023] Furthermore, a connecting rod is fixedly connected between the two limiting slots, and the connecting rod is located above the support bar.

[0024] Through the above technical solution, the connecting rod can be set up to bring the two limiting grooves and the telescopic rod together, so that when the two telescopic rods drive the limiting grooves to rise and fall, they can be at the same height as much as possible, so that the detection roller can detect the surface of the angle steel in a horizontal posture.

[0025] The beneficial effects of this invention are as follows: This invention, by setting clamps on a stand and controlling the clamping and loosening mechanism, allows workers to clamp and fix angle steel when the punching machine drills holes by driving a dual-axis motor, thereby ensuring drilling quality. After the punching machine drills the holes, an electric actuator can be used to drive an inspection roller to inspect the surface of the angle steel. The protruding positions of the inspection roller on the surface of the angle steel are marked with a marker pen, making it convenient for workers to correct the position. This invention features a vertical pole inside the lifting plate, with its two ends positioned at the bottom of the push plate and the top of the sliding rod, respectively. Since these two components are fixed, the only movable part is the lifting plate with rollers at the bottom. Therefore, when the rollers encounter a protrusion on the surface of the angle steel, the rollers will drive the lifting plate to rise together. At this time, the vertical pole can ensure that the lifting plate rises in the correct direction, and the marker pen on the side wall of the lifting plate can mark the position of the protrusion. This invention uses a tilted marker pen installed on the side wall of the lifting plate. Initially, the tilted marker pen will not contact the surface of the angle steel. However, the height of the marker pen cannot be too high. When the second spring causes the sleeve and the marker pen to rotate together around the side wall of the lifting plate, the marker pen needs to mark the surface of the angle steel as soon as possible so that it can mark the protrusions nearby, reducing the time that workers spend searching for the protrusions. Therefore, the height of the marker pen tip needs to be slightly higher than the bottom of the roller. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figure 1 - Figure 2 As shown, this embodiment provides a drilling and bending processing equipment for angle steel brackets, including a processing table 1. The processing table 1 includes a punching machine 2, a frame 3, and a bending machine 4. The frame 3 is fixedly installed on one side of the punching machine 2, and the bending machine 4 is installed on one side of the frame 3. The bending position of the bending machine 4 is on a straight line with the middle position of the punching machine 2. Therefore, when the operator pushes the angle steel, the angle steel can pass through the drilling and bending steps in a straight line. Several support bars 5 are provided in the frame 3. A guide platform 15 is installed on the side wall of the punching machine 2 facing away from the frame 3. A guide slope 16 is also provided at the end of the guide platform 15 away from the punching machine 2. The operator can insert the angle steel to be processed into the punching machine 2 through the guide platform 15. The guide platform 15 can limit the angle steel, which not only makes the process of pushing the angle steel into the punching machine 2 smoother, but also ensures that the position of the angle steel will not be deviated, thereby ensuring that the punching position is not wrong.

[0030] Combined with references Figure 5 and Figure 6Two clamps are fixedly mounted on the support bar 5, both clamps being located on the same support bar 5. Each clamp has a vertical plate 6 on its sidewalls, with an arc-shaped groove 7 on the sidewall of the vertical plate 6. Each clamp includes a drive rod 17, a fixed base 18, a top block 19, a swing rod 20, an inner rod 21, a stop block 22, an extension rod 23, and a fixed pad 24. The drive rod 17 is fixedly mounted on the sidewall of the top block 19, with both ends slidably connected to the inner walls of two opposing arc-shaped grooves 7. The swing rod 20 is fixedly connected to the bottom of the top block 19, and its other end is rotatably connected to the sidewall of the fixed base 18. The fixed base 18 is fixedly mounted on the top of the support bar 5. One end of the extension rod 23 is rotatably connected to the top of the fixed base 18, and its other end is rotatably connected to the fixed base 18. The fixed pad 24 is fixedly connected to the side wall and abuts against the top of the support rod 5. The drive rod 17, which moves in the arc groove 7, will drive the top block 19 to move. The top block 19, which is set on the top of the swing rod 20, will drive the swing rod 20 to move together. When the swing rod 20 rotates around the fixed seat 18, the internal rod 21 set inside the swing rod 20 will drive the stop block 22 to leave the position of the extension rod 23, thereby causing the fixed pad 24 to leave the position of the support rod 5. This makes it convenient for the operator to push the angle steel into the original position of the fixed pad 24. After the drive rod 17 returns to the initial position, the fixed pad 24 will return to the original position, thereby fixing the angle steel in the current position, which is convenient for the punching machine 2 to drill holes in the angle steel.

[0031] The fixing pad 24 is made of rubber. The lowest point of the fixing pad 24 is the same as the height of the fixing seat 18. Because the fixing pad 24 needs to be driven back to the initial position by the drive rod 17, and the angle steel pushed in by the staff is in the original position, the fixing pad 24 needs to be made of deformable rubber material, which can meet the needs of clamping the angle steel and avoid damaging the surface of the angle steel.

[0032] One end of the inner rod 21 is rotatably connected to the inner wall of the swing rod 20, and the other end is rotatably connected to the side wall of the extension rod 23. The stop block 22 is fixedly installed on the side wall of the inner rod 21, and the side wall of the stop block 22 abuts against the side wall of the extension rod 23. When the top block 19 is in a vertical state, the stop block 22 will abut against the side wall of the extension rod 23, thereby fixing the position of the extension rod 23, so that the fixing pad 24 can clamp the angle steel position. At the same time, when the top block 19 is driven to rotate by the drive rod 17, the inner rod 21 and the stop block 22 will move, so that the position of the extension rod 23 is no longer restricted. Since the extension rod 23 is also rotatably connected to the inner rod 21, the extension rod 23 and the fixing pad 24 are lifted.

[0033] from Figure 3 and Figure 4As can be seen, a dual-axis motor 8 is also installed on the side wall of the support bar 5. Both output ends of the dual-axis motor 8 are equipped with a tightening mechanism for controlling the clamp's tightness. The tightening mechanism includes an extension rod 25, a worm gear 26, a worm wheel 27, and a swing plate 28. The extension rod 25 is fixedly mounted on the output end of the dual-axis motor 8, and the worm gear 26 is fixedly mounted on the side wall of the extension rod 25 away from the dual-axis motor 8. A central rod 29 is rotatably connected between the two support bars 5, and the worm wheel 27 is fixedly mounted on the central rod 29. The worm gear 26 and the worm wheel 27 are connected... The wheel 27 is engaged, and the swing plate 28 is fixedly set on the side wall of the center rod 29. The other end of the swing plate 28 is fixedly connected to the side wall of the drive rod 17. The two output ends of the dual-axis motor 8 will rotate in the same direction, and the dual-axis motor 8 can be driven to rotate in both directions. Therefore, the dual-axis motor 8 will drive the extension rod 25 and the worm 26 to rotate. The worm wheel 27, which is engaged with the worm 26, will drive the swing plate 28 to swing, thereby causing the drive rod 17 to move in the arc groove 7, so that the clamp is driven to clamp the angle steel.

[0034] Reference Figure 7 - Figure 10 The support bar 5 between the clamp and the punching machine 2 is also equipped with several detection rollers. The detection rollers include a vertical rod 30, a sliding rod 31, a lifting plate 32, a roller 33, a first spring 34, a second spring 35, a sleeve 36, and a marker 37. The vertical rod 30 is located inside the lifting plate 32. The bottom of the lifting plate 32 is rotatably connected to the roller 33. The top of the vertical rod 30 is fixedly connected to the bottom of the push plate 14. The vertical rod 30 is fixedly set on the top of the sliding rod 31. The lifting plate 32 has a movable hole 40 inside, and the vertical rod 30 extends out of the movable hole 40. The two ends of the vertical rod 30 are respectively set at the bottom of the push plate 14 and the top of the sliding rod 31. These two parts are fixed. The only movable part is the lifting plate 32 with the roller 33 at the bottom. When it encounters a protrusion on the surface of the angle steel, the roller 33 will drive the lifting plate 32 to rise. The vertical rod 30 can ensure that it can rise in the correct direction.

[0035] The lifting plate 32 has a movement hole 38 on its side wall. The sliding rod 31 passes through the movement hole 38. The two ends of the sliding rod 31 are slidably connected to the inner walls of the two limiting grooves 10 respectively. One end of the first spring piece 34 abuts against the bottom of the sliding rod 31. The bottom of the movement hole 38 has a sliding groove 39. The other end of the first spring piece 34 is slidably connected to the inner wall of the sliding groove 39. The second spring piece 35 is fixed to the side wall of the first spring piece 34. The first spring piece 34 is "Z" shaped. The top of the first spring piece 34 is fixedly connected to the bottom of the sliding rod 31, and the bottom is slidably connected to the inner wall of the sliding groove 39. When the lifting plate 32 rises, the first spring piece 34 will be compressed. The "Z" shaped design makes the bottom of the first spring piece 34 slide in the sliding groove 39, which causes the first spring piece 34 to drive the second spring piece 35 to move laterally together, which causes the sleeve 36 to drive the marker pen 37 to mark the protruding position.

[0036] The other end of the second spring 35 passes through the side wall of the moving hole 38 and is rotatably connected to the side wall of the sleeve 36. The marker 37 is movably disposed inside the sleeve 36. One end of the sleeve 36 is rotatably connected to the side wall of the lifting plate 32. The height of the marker tip 37 is greater than the height of the bottom of the roller 33. The height of the roller 33 is the same as the height of the punching machine 2. In the initial case, the tilted marker 37 will not contact the surface of the angle steel. Therefore, the height of the marker 37 should be relatively high, but not too high. When the second spring 35 drives the sleeve 36 and the marker 37 to rotate together, the marker 37 needs to mark the surface of the angle steel as soon as possible. Therefore, the height of the marker 37 needs to be slightly higher than the height of the roller 33. Since the marker 37 is movably disposed inside the sleeve 36, when the marker 37 cannot mark the position, the operator can easily remove it for replacement. The movable setting here includes, but is not limited to, threaded connection, magnetic connection or adhesive connection. The color of the marker 37 can also be changed according to the requirements to meet the needs of different application scenarios.

[0037] The first spring 34 is positioned so that the sliding rod 31 is at the top of the moving hole 38. At this time, the roller 33 will be in contact with the surface of the angle steel. If it encounters a protrusion on the surface of the angle steel, the protrusion will push the roller 33 upward. Therefore, the lifting plate 32 will be driven upward by the roller 33, which will compress the first spring 34. The bottom of the first spring 34 slides in the sliding groove 39, which will drive the second spring 35 to move away from the sleeve 36. The rotating sleeve 36 will drive the marker pen 37 to rotate together, thereby marking the position of the protrusion for the convenience of the staff for subsequent correction.

[0038] Combined with references Figure 1 and Figure 2 The table 3 is equipped with two sets of telescopic rods 9. Each telescopic rod 9 has a limiting groove 10 fixedly installed at its top. These telescopic rods 9 are electrically operated. Because the thickness of the angle steel to be processed may vary, the distance between the roller 33 and the support bar 5 also needs to be adjusted. The electrically operated telescopic rods 9 allow for the adjustment of the limiting groove 10 and the roller 33, thus meeting the processing requirements of angle steels of different thicknesses. A connecting rod 41 is fixedly connected between the two limiting grooves 10. The connecting rod 41 is located above the support bar 5. The two limiting grooves 10 and the telescopic rods 9 can be brought together so that when the two telescopic rods 9 drive the limiting grooves 10 to rise and fall, they can be at the same height as much as possible. This allows the detection roller to detect the surface of the angle steel in a horizontal posture. The detection roller slides in the limiting grooves 10. A top plate 11 is fixedly installed on the side wall of the upright plate 6. Several moving grooves 12 are opened on the side wall of the top plate 11. The positions of the several moving grooves 12 correspond one-to-one with the positions of several detection rollers. An electric push rod 13 is also fixedly installed on the side wall of the top plate 11. A push plate 14 is fixedly connected to the output end of the electric push rod 13.

[0039] The working principle of this embodiment is as follows: In the initial state, the fixed pad 24 does not contact the surface of the support rod 5. Then, the operator pushes the angle steel into the punching machine 2 through the guide table 15. During the pushing process, the dual-axis motor 8 is started. The two output ends of the dual-axis motor 8 will rotate in the same direction. Therefore, the dual-axis motor 8 will drive the extension rod 25 and the worm gear 26 to rotate. The worm wheel 27 meshing with the worm gear 26 will drive the swing plate 28 to swing, thereby causing the drive rod 17 to move in the arc groove 7. The drive rod 17 moving in the arc groove 7 will drive the top block 19 to move. When the swing rod 20 is moved, the top block 19 set at the top of the swing rod 20 will drive the swing rod 20 to move together. When the swing rod 20 rotates around the fixed base 18, the inner rod 21 set inside the swing rod 20 will drive the stop block 22 to leave the position of the extension rod 23 together, thereby causing the fixed pad 24 to leave the position of the support rod 5, so that the operator can push the angle steel into the original position of the fixed pad 24. After the drive rod 17 returns to the initial position, the fixed pad 24 will return to the original position, thereby fixing the angle steel in the current position, which is convenient for the punching machine 2 to drill holes in the angle steel. After punching a hole in one position on the surface of the angle steel, the dual-axis motor 8 can be driven in reverse. The reverse operation of the above steps will cause the fixing pad 24 to leave the angle steel, which will make it easier for the workers to push the angle steel back into the punching machine 2, thus making it easier for the punching machine 2 to drill holes in other positions of the angle steel. When the drilled hole reaches below the inspection roller, the electric push rod 13 can be driven, causing the push plate 14 to move along the direction of the motion groove 12. The upright rod 30 at the bottom of the push plate 14 will drive the lifting plate 32 and the sliding rod 31 to move along the direction of the limiting groove 10. The elasticity of the first spring 34 will cause the sliding rod 31 to be at the top of the motion hole 38. At this time, the roller 33 will contact the surface of the angle steel. If it encounters a protrusion on the surface of the angle steel, the protrusion will push the roller 33 upward. Therefore, the lifting plate 32 will be driven upward by the roller 33, which will compress the first spring 34. The bottom of the first spring 34 slides in the sliding groove 39, which will drive the second spring 35 to move away from the sleeve 36. The rotating sleeve 36 will drive the marker pen 37 to rotate together, thereby marking the position of the protrusion for the convenience of the staff for subsequent correction. After the angle steel is corrected, the angle steel can enter the final bending machine 4 for bending processing.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
