Description

Technical Field

[0001] This utility model relates to the technical field of continuous punching and chamfering of a single angle steel, specifically to an angle steel position adjustment conveyor frame for ultra-high voltage transmission towers. Background Technology

[0002] Ultra-high voltage (UHV) transmission refers to transmission lines with AC voltage levels exceeding 1000kV or DC voltage levels exceeding ±800kV. UHV transmission lines utilize a large number of UHV towers, whose main components are angle steel members. Due to the large size of UHV transmission towers, their angle steel members are generally 200mm*200mm in size and 26mm thick; some even use 360mm*360mm angle steel members with a thickness of 32mm.

[0003] Because transmission towers are large, their prisms are also quite long. However, current technology used by transmission tower manufacturers involves first cutting a single angle steel bar into multiple angle steel blanks according to production requirements. These blanks are then mechanically processed, including bending, drilling, and chamfering, to obtain short angle steel components (typically within 2 meters in length). Finally, these short components are assembled on-site to form the prism. This existing technology works because the prism is not a completely straight structure; it has bends in certain sections. Therefore, shorter angle steels are used, and by creating angles during assembly or by bending shorter angle steels, the assembled transmission tower prism meets design requirements.

[0004] The existing technology of cutting angle steel into short pieces and then splicing them is actually a compromise due to the limitations of current production technology and equipment, which cannot directly process whole angle steels. Components formed by splicing multiple short angle steel pieces have relatively poor overall strength compared to components formed from a single whole angle steel. Furthermore, the bolts used to splice adjacent angle steels are more prone to corrosion than the angle steel itself. Cutting whole angle steel into blanks before processing obviously results in more waste than processing a whole angle steel directly, and it also adds cutting and splicing processes. The processing errors resulting from processing multiple short angle steel pieces are greater than those from processing a whole angle steel, thus increasing installation errors at the transmission tower construction site. This leads to increased installation difficulty and may even affect the actual strength performance of the transmission tower after installation.

[0005] Therefore, in the applicant's research and development process, how to reduce the number of angle steel components and the number of times angle steel components are spliced ​​in the disassembly production of power transmission tower structures, and how to use whole angle steel components for splicing as much as possible, is the research direction of the technical personnel.

[0006] Although the applicant has developed effective bending technology and equipment for angle steel during the production and R&D process, solving the technical bottleneck of bending whole angle steel, the length of the whole angle steel is too long (the whole length of a 200mm*200mm, 26mm thick angle steel piece is generally in the range of 10-15 meters; the whole length of a 360mm*360mm, 32mm thick angle steel piece is generally in the range of 15-20 meters, and some even reach 25 meters). Existing equipment cannot directly process whole angle steel, and there is currently no suitable special equipment on the market for the continuous production of punching and chamfering of whole angle steel. This results in relatively low production efficiency for punching and chamfering whole angle steel, which seriously affects the applicant's production efficiency.

[0007] Therefore, the applicant urgently needs to develop an automated production line and related components that can continuously punch and chamfer a whole angle steel. Summary of the Invention

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an angle steel position adjustment conveyor for ultra-high voltage transmission towers. Through the angle steel position adjustment conveyor, the angle steel located in the unloading rack A can be adjusted and positioned along the length of the angle steel. After the angle steel is transferred from the turnover feeding rack A to the angle steel feeding conveyor, the angle steel receiving device can directly perform corresponding operations on the angle steel, ensuring the smooth progress of subsequent automation.

[0009] The technical solution adopted by this utility model is:

[0010] A position adjustment conveyor frame for angle steel in ultra-high voltage transmission towers is characterized in that: the position adjustment conveyor frame includes two parallel and fixedly arranged frame bodies B. The top of each frame body B has a corresponding turnover notch corresponding to the position of each turnover frame A. The turnover notch corresponding to the outermost turnover frame A at both ends is called turnover notch A, and the remaining turnover notches are called turnover notches B. The material drop frames A are located within the range of the corresponding turnover notch A. When a turnover frame A rotates to the position of the angle steel position adjustment conveyor frame, the turnover frame A is simultaneously located within the corresponding turnover notch A or turnover notch B. Multiple conveying rollers A are evenly spaced between the frame bodies B, on both sides of turnover notch A, and on the top of both sides of turnover notch B. The rim of each conveying roller A has an annular groove matching the angle of the angle steel. The conveying roller A is connected to a drive motor B via a transmission belt A. The drive motor B is fixedly connected to one of the frame bodies B, and the conveying rollers A rotate synchronously, in the same direction, and at the same speed.

[0011] A further improvement of this utility model is that the axle A end of the conveyor roller A extends out of the side end face of the frame B with the drive motor B facing away from the other frame B and is coaxially fixed with a corresponding transmission wheel A. The end face of the frame B with the transmission wheel A, the bottom of the two sides of the turnover gap A, and the bottom of the two sides of the turnover gap B are all rotatably equipped with transmission wheels B. When the transmission belt A is wound around the top of the transmission wheel A to one side of the turnover gap A or one side of the turnover gap B, the transmission belt A is wound downwards and wound around the bottom of the transmission wheel B to the other side of the turnover gap A or the other side of the turnover gap B. Then the transmission belt A is wound upwards and wound around the top of the transmission wheel A on the corresponding side.

[0012] A further improvement of this utility model is that the frame B has an end face on the side where the transmission wheel A is located, and a transmission wheel C is respectively provided directly below the transmission wheels B on both sides of the turnover gap A, and a transmission wheel D is respectively provided directly below the transmission wheels B on both sides of the turnover gap B. The transmission belt A is respectively wrapped around the top of the transmission wheel C and the bottom of the transmission wheel D.

[0013] A further improvement of this utility model is that the drive motor B is located at the bottom of one end of the frame B, and the other end of the frame B with the drive motor B is rotatably connected to a transmission wheel E. The transmission belt A is wound around the drive wheel of the drive motor B from the bottom, and then wound around the transmission wheel A at the top end of the frame B. After the transmission belt A is wound around the transmission wheel A at the other end of the top of the frame B, it is wound around the bottom of the transmission wheel E, and then wound around the transmission wheel C and the transmission wheel D in sequence, until finally it is wound around the drive wheel of the drive motor B.

[0014] A further improvement of this utility model is that the end of the angle steel position adjustment conveyor frame away from the stamping machine is also provided with an angle steel adjustment and positioning device. When the angle steel position adjustment conveyor frame adjusts and conveys the end of the angle steel away from the stamping machine to make contact with the angle steel adjustment and positioning device, the angle steel is just matched and connected with the angle steel feeding conveyor frame when it is transferred to the angle steel feeding conveyor frame through the angle steel turnover feeding frame A.

[0015] A further improvement of this utility model is that the angle steel adjustment and positioning device includes a frame H, a sliding plate C is tunably fixedly connected to the top surface of the frame H, and a positioning plate is fixedly provided at the end of the top surface of the sliding plate C away from the angle steel position adjustment conveyor frame. The plane of the end face of the positioning plate is perpendicular to the conveying direction of the angle steel position adjustment conveyor frame, and the vertical projection of the angle steel conveyed by the angle steel position adjustment conveyor frame toward the positioning plate is within the range of the positioning plate.

[0016] A further improvement of this utility model is that a guide roller is rotatably connected to the end of the top surface of the slide plate C near the angle steel position adjustment conveyor frame. The two ends of the axle C of the guide roller are rotatably connected to the connecting uprights fixed on both sides of the top surface of the slide plate C. The structure of the guide roller is the same as that of the conveyor roller A of the angle steel position adjustment conveyor frame, and the guide roller is located on the straight line where each conveyor roller A is located.

[0017] A further improvement of this utility model is that horizontally arranged slide rails D are provided on both sides of the top surface of the frame H, and a matching slide groove is provided at the bottom of the slide plate C corresponding to the slide rails D. The slide plate C is locked and fixed to the slide rails D by locking bolts B.

[0018] The beneficial effects of this utility model are as follows:

[0019] First, the angle steel position adjustment conveyor frame for ultra-high voltage transmission towers of this utility model enables the angle steel located in the unloading rack A to be adjusted and positioned along the length of the angle steel. After the angle steel is transferred from the turnover feeding rack A to the angle steel feeding conveyor frame, the angle steel receiving device can directly perform corresponding operations on the angle steel, ensuring the smooth operation of subsequent automation.

[0020] Secondly, the angle steel position adjustment conveyor frame for ultra-high voltage transmission towers of this utility model, through the setting of the angle steel adjustment and positioning device, enables angle steels of different lengths and specifications to be adapted to the subsequent angle steel feeding device after passing through the angle steel adjustment and positioning device, thereby improving the applicability of the angle steel position adjustment conveyor frame and the production line.

At the same time, lifting drive device 4312 drives lifting seat 4302 to move slide plate A4303 and vertical fixture downward to the maximum stroke position. Horizontal drive device 4315 drives slide plate A4303 to move vertical fixture relative to transmission box 4300 away from the press 5 to the maximum stroke position. Cylinder C4320 drives drive rocker arm 4324 to swing, thereby moving fixture drive rod 4325 away from the vertical fixture. This causes the clamping arm 4307 of the vertical fixture to swing around swing axis 4332 under the elastic restoring force of spring 4333, so that the end of clamping arm 4307 corresponding to the opening of the vertical fixture moves away from the opening until the opening of the vertical fixture is opened to the maximum opening state.

[0108] In this application, the angle steel 10 is placed along the feeding direction parallel to the angle steel feeding conveyor 4 on the link of the conveyor chain 101 on the frame A100 of the angle steel loading conveyor 1, where the corresponding pusher protrusion 107 is provided, so that the angle steel 10 is perpendicular to the conveying direction of the conveyor chain 101. One side plate of the angle steel 10 placed on the conveyor chain 101 is in contact with the conveyor chain 101. Place the angle steel 10 so that the other side plate is erected and located in front of the conveyor chain 101 in the conveying direction, i.e., facing the angle steel feeding conveyor frame 4. Then, drive motor A103 drives conveyor chain 101 to convey angle steel 10 to the side of angle steel feeding conveyor frame 4 until conveyor chain 101 conveys angle steel 10 to sprocket A106 located at the position of unloading frame A102. Under the action of gravity, the side plate of angle steel 10 that was originally in contact with the chain link moves down along the corresponding position of the chain link and the part of the connecting frame A100 of unloading frame A102 to the bottom of the "V" shaped structure. At this time, the bending point of angle steel 10 is exactly located at the bottom of the "V" shaped structure of unloading frame A102. At this time, drive motor A103 stops.

[0109] Since the angle steel 10 located at the bottom of the unloading rack A102 is also located in the annular groove of the conveyor roller A201 of the angle steel position adjustment conveyor rack 2 and is in contact with the conveyor roller A201, the drive motor B202 drives each conveyor roller A201 to move the angle steel 10 toward the positioning plate 902 until the end of the angle steel 10 is in positioning contact with the positioning plate 902. At this time, the drive motor B202 stops.

[0110] At this time, the drive motor C304 drives the transmission shaft B301, causing the radial rotating rod A302 and the turnover frame A303 to rotate around the axis of the transmission shaft B301. Since the sprockets B307 and C308 are connected by the transmission chain A306, and the diameters and number of teeth of the sprockets B307 and C308 are the same, the turnover frame A303 can always keep the opening of the "V" shape facing upward during the rotation around the axis of the transmission shaft B301. When the turnover frame A303 rotates from bottom to top to the position of the turnover gap A203 and turnover gap B204 of the angle steel position adjustment conveyor frame 2, it will lift the angle steel 10 that is in contact with the conveyor roller A201 and move it away from the angle steel position adjustment conveyor frame 2 and the unloading frame A102. At this time, the drive motor A103 drives the conveyor chain 101 again to convey the angle steel 10 on the conveyor chain 101 to the unloading frame A102; and drive the angle steel 10 away from the conveyor chain 10. The turnover frame A303 of the support roller A201 and the unloading frame A102 continues to rotate around the axis of the drive shaft B301 and rotates to the angle steel feeding conveyor frame 4. When the turnover frame A303 rotates from top to bottom to the gap position between two adjacent feeding roller frames 44, the angle steel 10 is placed on the feeding rollers 442 on both sides of the feeding roller frame 44. The turnover frame A303 continues to rotate under the action of the drive motor C304 until it separates from the angle steel feeding conveyor frame 4. At this time, the drive motor C304 stops.

[0111] Drive motor E4206 drives electromagnet 4203 to move upward to its maximum stroke. At this time, the slot 4214 of electromagnet 4203 is close to or in contact with angle steel 10, and the end of angle steel 10 away from the press 5 extends out of electromagnet 4203. Then drive device 4204 energizes electromagnet 4203, and the magnetic force of electromagnet 4203 attracts and fixes angle steel 10. Then drive motor D4205 drives electromagnet 4203 to move away from press 5 to its maximum stroke. At this time, the distance between the end of angle steel 10 extending out of electromagnet 4203 and the opening of vertical fixture is exactly the stroke of horizontal drive device 4315 driving slide plate A4303 to move.

[0112] Then, the horizontal drive device 4315 drives the slide plate A4303 to move towards the press 5 to its maximum stroke position. At this time, the end of the angle steel 10 extending from the electromagnet 4203 is exactly located at the opening of the vertical fixture. Then, the cylinder C4320 drives the drive lever 4324 to swing, thereby driving the fixture drive rod 4325 to swing the clamping arms 4307 of the vertical fixture against the force of the spring 4333 around the swing axis E4332 until the electromagnet 4203 is attracted and fixed, and the bent part of the angle steel 10 extending from the electromagnet 4203 is clamped and fixed. The rear drive unit 4204 de-energizes the electromagnet 4203. At this time, the electromagnet 4203 only contacts or separates from the angle steel 10 clamped and fixed by the vertical fixture. In addition, the drive motor E4206 drives the electromagnet 4203 to move downward to the maximum stroke position, and the drive motor D4205 drives the electromagnet 4203 to move towards the press 5 to the maximum stroke position, that is, the electromagnet 4203 returns to the starting position. Then, the drive motor F4309 drives the transmission box 4300 to move the vertical fixture and the angle steel 10 fixed to the vertical fixture towards the press 5.

[0113] During the process of angle steel 10 being conveyed to the stamping machine 5 via angle steel feeding device 43, whenever the chamfering or punching position of angle steel 10 is conveyed to the corresponding position of the corresponding stamping die of the stamping machine 5, the drive motor F4309 of angle steel feeding device 3 pauses its drive. After the punching machine 5 completes the corresponding stamping action, the drive motor F4309 continues to convey angle steel 10 to the stamping machine 5. The end of angle steel 10 after being stamped by the stamping machine 5 is conveyed from the discharge end of the stamping machine 5 to the angle steel discharge conveyor 6. When angle steel 10 is conveyed to the angle steel discharge conveyor 6 and contacts the conveying roller B601 of the angle steel discharge conveyor 6, the drive motor G602 drives the conveying roller B601 to contact the drive motor F4309. The driving transmission box 4300's traveling wheels 4308' synchronously transmit the angle steel 10 in the same direction and at the same speed until the next chamfering or punching position of the angle steel 10 is transmitted to the corresponding position of the corresponding stamping die of the stamping machine 5. At this time, the driving motors F4309 and G602 simultaneously stop driving, so that the punching machine 5 completes the corresponding stamping action. The above-mentioned synchronous transmission of the angle steel 10 by the angle steel feeding device 43 and the angle steel discharge conveyor 6 and the simultaneous pausing of the driving motors F4309 and G602 by the stamping machine 5 perform the corresponding stamping action on the angle steel 10 until the angle steel feeding device 43 moves to the maximum stroke position facing the stamping machine 5. At this time, the driving motors F4309 and G602 simultaneously stop driving again. The drive is paused. At this time, most of the angle steel 10 is located on the angle steel discharge conveyor 6. After the angle steel 10 is separated from the vertical fixture, the angle steel discharge conveyor 6 can drive the angle steel 10 to continue to be conveyed. Then, the cylinder C4320 drives the drive swing rod 4324 to swing, thereby driving the fixture drive rod 4325 to retract. Then, the clamping arms 4307 of the vertical fixture swing around the swing axis E4332 under the restoring force of the spring 4333 until the opening of the vertical fixture is at its maximum. Then, the horizontal drive device 4315 drives the slide plate A4303 to move away from the press 5 to the maximum stroke. The lifting drive device 4312 drives the lifting seat 4302 to move the slide plate A4303 and the vertical fixture upward to the maximum stroke. Then, the drive motor G602 drives the conveyor roller B601 again to continue conveying the angle steel 10 to the angle steel discharge conveyor frame 6. At the same time, the drive motor F4309 drives the angle steel feeding device 43 to move away from the punching machine 5. When the next chamfering position or punching position of the angle steel 10 is conveyed to the corresponding position of the corresponding stamping die of the punching machine 5, the drive motor G602 stops driving, so that the punching machine 5 completes the corresponding stamping action. The conveying of the angle steel 10 by the angle steel discharge conveyor frame 6 and the corresponding stamping action of the punching machine 5 on the angle steel 10 after the drive motor G602 stops driving are repeated until the angle steel 10 completely leaves the punching machine 5 and is fully supported by the angle steel discharge conveyor frame 6, at which point the drive motor G602 stops driving.When the angle steel feeding device 43 moves to its maximum stroke position in the direction away from the punching machine 5, the drive motor F4309 stops driving, and then the lifting drive device 4312 drives the lifting seat 4302 to move the sliding plate A4303 and the vertical clamp downward to the maximum stroke position.

[0114] When the drive motor F4309 drives the angle steel feeding device 43 to move away from the punching machine 5, the drive motor C304 drives the transmission shaft B301 again to drive the radial rotating rod A302 and the turnover frame A303 to rotate around the axis of the transmission shaft B301, thereby lifting the angle steel 10 that is in contact with the conveying support roller A201 away from the angle steel position adjusting conveyor frame 2 and the unloading frame A102 and conveying it to the feeding rollers 442 on both sides of the feeding roller frame 44.

[0115] When angle steel 10 completely leaves the punching machine 5 and is fully supported by the angle steel discharge conveyor 6, and when motor G602 stops driving, drive motor H704 drives transmission shaft C701 to drive radial rotor B702 and turnover frame B703 to rotate around the axis of transmission shaft C701. Since sprockets D707 and E708 are connected by transmission chain B706, and sprockets D707 and E708 have the same diameter and number of teeth, turnover frame B703 rotates around the axis of transmission shaft C701. Always maintaining the "V"-shaped opening facing upwards, when the turnover frame B703 rotates from bottom to top to the turnover gap C603 position of the angle steel discharge conveyor frame 6, it lifts the angle steel 10 that is in contact with the conveyor roller B601 and removes it from the angle steel discharge conveyor frame 6; the turnover frame B703, which drives the angle steel 10 away from the conveyor roller B601, continues to rotate around the axis of the drive shaft C701 and rotates towards the angle steel collection frame 8. When the turnover frame B703 rotates from top to bottom to the frame body G80... When the angle steel 10 is placed at the bottom of the "V" shaped structure of the material drop rack B805 on both sides, the side plate edge of the angle steel 10 on the side away from the angle steel discharge conveyor 6 extends out of the connection between the material drop rack B805 and the horizontal longitudinal bar 802. The turnover rack B703 continues to rotate downward under the action of the drive motor H704 until it separates from the material drop rack B805 and continues to rotate to the lowest position. At this time, the drive motor H704 stops.

[0116] After the turnover rack B703 conveys the angle steel 10 into the unloading rack B805, the worker on one side of the angle steel collecting rack 8 flips the angle steel 10 inside the unloading rack B805 upwards around the connection between the diagonal bar of the unloading rack B805 and the horizontal longitudinal bar 802 of the frame G800. This flips the side plate of the angle steel 10, which was originally facing away from the angle steel discharge conveyor 6, so that it is in contact with the horizontal longitudinal bar 802. Then, the angle steel 10 is moved along the horizontal longitudinal bar 802 in the direction away from the angle steel discharge conveyor 6 to the connection between the horizontal longitudinal bar 802 and the horizontal crossbar 803. The angle steel 10 is then moved further away from the angle steel discharge conveyor 6 until it is in contact with the horizontal longitudinal bar 802. The side plate extends out of the horizontal longitudinal bar 802. Then, using the height difference between the horizontal longitudinal bar 802 and the horizontal crossbar 803, the edge of the angle steel 10 extending out of the horizontal longitudinal bar 802 is flipped downward around the top of the horizontal longitudinal bar 802, facing away from the edge of the angle steel discharge conveyor 6. The edges of the side plates on both sides of the angle steel 10 are in contact with the horizontal crossbar 803. At this time, the bent part of the angle steel 10 is facing upward. When there is another angle steel 10 placed in the unloading rack B805, the above operation is repeated. The angle steel 10 in the unloading rack B805 is flipped until the edges of the two side plates are in contact with the horizontal crossbar 803. Then, the end of the angle steel 10 extending out of the frame body G800 is pressed downward so that the other end of the angle steel 10 is wrapped around the edge of the horizontal crossbar 803. The outermost edge of the outermost horizontal crossbar 803 at the lower end is raised upwards to a height higher than the top of the previous angle steel 10. Then, the raised end of the angle steel 10 is swung around the edge of the horizontal crossbar 803 to above the previous angle steel 10. After the raised end of the angle steel 10 contacts the top surface of the previous angle steel 10, the lower end of the angle steel 10 is raised to a height higher than the corresponding end of the previous angle steel 10. The raised angle steel 10 is then swung around the other end placed on the previous angle steel 10 until the raised end of the angle steel 10 is above the previous angle steel 10. Next, the end of the angle steel 10 is swung towards the bend at the top of the previous angle steel 10 and the outer wall of the side plate. Finally, the end placed on the upper... The square angle steel 10 is moved along its length until the ends of the angle steel 10 are aligned, forming an angle steel stack. The above action is repeated until the number of angle steel 10 stacked in the angle steel stack reaches the required number of angle steel for bundling and packaging. Then, the angle steel stack is moved along the length of the horizontal crossbar 803 to the position of the horizontal longitudinal bar 802 at the end of the frame G800 away from the angle steel discharge conveyor 6. The operator bundles and fixes the angle steel stacks. The bundling positions are located on the angle steel stacks between two adjacent frames G800 and the end of the angle steel stack extending from the outermost frame G800 and facing away from other frames G800. Finally, the angle steel stacks are hoisted and transferred to the bundling points by the hoisting and turnover equipment.

[0117] The stamping machine 5 can directly adopt existing technology, such as the structure of the processing head and the matching device for temporarily pressing the angle steel during stamping disclosed in the patent application number 202220362618.2, so as to realize that during the transmission of the angle steel 10, the corresponding positions of the side plates of the angle steel 10 are respectively punched with chamfers and punched with holes.

[0118] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers, which enables automated and continuous production of punching and chamfering of a single piece of angle steel. This not only improves production efficiency but also enhances the positional accuracy of the holes on the angle steel, thereby improving the convenience of subsequent transmission tower installation and the installation accuracy of different components.

[0119] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel.

[0120] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. Through the structure of the pusher protrusion in the conveyor chain of the angle steel feeding conveyor, the angle steel can be conveyed in an orderly manner. Moreover, the positioning slot and the inclined setting of the pusher protrusion can both position the edge of the angle steel side plate and limit the edge of the angle steel side plate. This prevents the angle steel from tipping over to the front side due to instability during the conveyor chain and falling into the unloading rack A, causing the bent part of the angle steel to not correspond to the bottom of the unloading rack A.

[0121] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. Through the set angle steel position adjustment conveyor frame, the angle steel located in the unloading rack A can be adjusted and positioned along the length of the angle steel.

The sprocket B, which is fixed to the bearing seat of the frame body C, is rotatably connected to the other end of the radial rotating rod A. The sprocket B is connected to the sprocket C via a transmission chain A, thereby ensuring that while the turnover frame A rotates around the radial rotating rod A, the opening of the "V"-shaped structure of the turnover frame A always remains upward, thus achieving the turnover effect of the angle steel.

[0124] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. Through the action of the angle steel receiving device, the angle steel transferred from the turnover frame A to the angle steel feeding conveyor frame is connected to the angle steel feeding device. This ensures that the angle steel feeding device is always in the starting position when the angle steel is fixedly connected, thereby ensuring the accuracy of the processing points during subsequent angle steel stamping and the consistency of stamping processing for each angle steel.

[0125] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. Through the structure of the angle steel feeding device, the angle steel end is clamped and fixed, then conveyed to the punching machine to the corresponding position, paused, and then punched. After punching, it is conveyed to the next corresponding position, paused again, and then punched again, until it is conveyed to the maximum stroke, then separates from the angle steel and automatically returns to the starting position.

[0126] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. The lifting drive device of the angle steel feeding device drives the lifting seat to move the vertical clamp upward to the maximum stroke and then move it away from the punching machine to the maximum stroke. This allows the angle steel feeding device to return to the starting position while the angle steel feeding device, angle steel position adjustment conveyor, and turnover conveyor A can work simultaneously without being affected by the angle steel feeding device, thereby further improving production efficiency.

[0127] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. The vertical clamp structure allows the angle steel to be moved towards the punching machine by clamping and fixing only the bend at the end of the angle steel, without interfering with the feed rollers.

[0128] This utility model relates to a production line for continuous punching and chamfering of a single angle steel for ultra-high voltage transmission towers. The vertical clamp can automatically open when the clamp drive rod retracts due to the restoring force of the spring, which facilitates the tightening and fixing of the bending point at the end of the next angle steel.

[0129] This utility model relates to a continuous punching and chamfering production line for integral angle steel used in ultra-high voltage transmission towers. Through the adjustable fixing of the sliding plate A and the reinforcing side rod, the horizontal drive device can move the vertical clamp to accommodate angle steel of different lengths and specifications, thereby ensuring the fixation of the vertical clamp and the angle steel and improving the applicability of the angle steel feeding device.

[0130] This utility model relates to a production line for continuous punching and chamfering of a single angle steel for ultra-high voltage transmission towers. By extending the reinforcing side bars on both sides of the vertical plate, the bending resistance of the vertical clamp connected and fixed to the extended vertical plate can be improved. Under the drive of the horizontal drive device, the movement consistency between the vertical clamp and the slide plate A is ensured, and under the drive of the drive motor F, the movement consistency between the vertical clamp and the transmission box is ensured.

[0131] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. Through the action of the angle steel discharge conveyor, the punched or chamfered parts of the angle steel are discharged and conveyed by the punching machine. The angle steel is then transferred to the angle steel collection rack via turnover rack B for collection, bundling, and transfer to other processes.

[0132] This utility model relates to a production line for continuous punching and chamfering of a single piece of angle steel for ultra-high voltage transmission towers. The turnover frame B of the angle steel turnover feeding rack B is rotatably connected to one end of the radial rotating rod B via a sprocket E. The sprocket D, which is fixed to the bearing seat of the frame body F, is rotatably connected to the other end of the radial rotating rod B. The sprocket D is connected to the sprocket E via a transmission chain B, thereby ensuring that the opening of the "V"-shaped structure of the turnover frame B always faces upward while rotating around the radial rotating rod B, thus achieving the turnover effect of the angle steel.

[0133] This utility model relates to a continuous punching and chamfering production line for ultra-high voltage transmission towers using whole angle steel. The angle steel collecting rack facilitates the transfer of punched angle steel from the angle steel turnover feeding rack B to the unloading rack B. The operator then flips and moves the angle steel from the unloading rack B onto the frame G. The angle steel on the frame G has its bends facing upwards and its side edges contacting the horizontal crossbars of the frame G, allowing for the subsequent stacking of the remaining angle steel collected by the collecting rack. After being stacked into an angle steel pile, the pile is moved along the horizontal crossbar to the side of the angle steel collecting rack away from the angle steel discharge conveyor, thus facilitating the bundling and turnover of the angle steel pile.

[0134] This utility model relates to a production line for continuous punching and chamfering of whole angle steel for ultra-high voltage transmission towers. Through the "V"-shaped structure of the feeding rack B, the angle steel in the turnover rack B is placed at the bottom of the feeding rack B at the bend.

[0135] This utility model relates to a production line for continuous punching and chamfering of a single piece of angle steel for ultra-high voltage transmission towers. The inclined bar of the "V"-shaped structure of the unloading rack B, which is connected to the horizontal longitudinal bar, is shorter than the width of the angle steel side plate, making it easy for the angle steel inside the unloading rack B to be easily flipped onto the horizontal longitudinal bar.

[0136] This utility model relates to a production line for continuous punching and chamfering of integral angle steel for ultra-high voltage transmission towers. The top surface of the horizontal longitudinal bar is higher than the top surface of the horizontal transverse bar, which facilitates the flipping of the angle steel on the horizontal longitudinal bar onto the horizontal transverse bar and ensures that the bent part of the angle steel on the horizontal transverse bar is located at the top, and the edges of the two side plates are in horizontal balance contact. Furthermore, the angle steel or angle steel pile located on the horizontal transverse bar is limited by the horizontal longitudinal bar when moving along the horizontal transverse bar, preventing the angle steel or angle steel pile on the horizontal transverse bar from falling off.

[0137] This utility model relates to a production line for continuous punching and chamfering of whole angle steel for ultra-high voltage transmission towers. The packaging interval area facilitates operators to bundle and pack the middle part of the angle steel stack, and ensures the safety of the angle steel pairs during turnover.
