Description

Technical Field

[0001] The present invention relates to the field of cutting of power transmission tower components, and specifically to a cutting device for processing power transmission tower components and a method for using the same. Background Art

[0002] The primary function of a power transmission tower is to provide a stable support for the transmission line, ensuring that the conductor and the lightning protection wire can be accurately suspended in the air according to the predetermined line direction. A power transmission tower mainly consists of a tower head, a tower body, and a tower foundation. The tower head includes a conductor cross arm, a lightning protection wire cross arm, and an insulator string. The tower body includes main members, diagonal members, and horizontal members. The tower foundation includes a foundation and anchor bolts. Therefore, a power transmission tower is assembled from various tower components. A power transmission tower usually presents a tall and complex three-dimensional structure, and angle iron is one of the key materials for constructing the main body of this framework.

[0003] Among them, numerous angle irons are combined together by means of welding, bolt connection, etc. to form the skeleton of the power transmission tower, which can provide a stable installation foundation for the whole power transmission tower, enabling the power transmission tower to bear its huge self-weight and enabling the power transmission tower to withstand the external forces generated under different environmental conditions. The columns, cross arms, etc. of the tower body are mainly composed of angle irons, and a strong framework is formed by connecting the angle irons with each other to ensure high stability of the power transmission tower in the vertical and horizontal directions.

[0004] Before installing the angle iron, it is necessary to cut the angle iron into an appropriate length. When cutting the angle iron, a cutting device is usually required. The cutting device for angle iron is usually a hydraulic cutting device. The hydraulic cutting device mainly consists of a hydraulic system, a cutting knife, a cutting table, and a feeding system. The angle iron is conveyed to the cutting table through the feeding system, and the cutting knife is driven to move by the hydraulic system, so that the cutting knife cuts the angle iron.

[0005] However, during the process of cutting the angle iron by the hydraulic cutting device, the feeding system conveys a single angle iron. After the angle iron is cut, it is necessary to wait for the feeding system to reset, and then the angle iron is placed in the feeding system manually or by a hoisting device. Only at this time can the feeding system convey the angle iron again. A large amount of time is wasted in this process, resulting in the hydraulic cutting device needing to stop for too long, causing the number of angle irons cut in the same time to decrease. Based on the above problems, this application proposes a cutting device for processing power transmission tower components and a method for using the same. Summary of the Invention

[0019] A usage method of a cutting device for processing tower components of a power transmission tower includes the following steps:

[0020] Step 1: Place the angle iron body of the power transmission tower on the two placing tables at the rear. Drive the output end of the telescopic cylinder to push the pushing block downward, so that the connecting component is horizontally aligned with the angle iron body. Drive the output end of the driving motor to drive the rotating shaft to rotate. At this time, the rotating shaft cannot drive the installation shaft to rotate through the connecting component, and drive the rotating screw rod to rotate through the rotating shaft. The screw sleeve drives the moving plate to move to the right, and drives the guiding sleeve to slide on the surface of the guiding rod through the moving plate, so that the moving plate drives the pushing block to push the angle iron body to move to the right through the telescopic cylinder.

[0021] Step 2: When the angle iron body moves into the conveying shaft, limit the position of the angle iron body through the conveying shaft, so that the angle iron body enters the cutting component. Cut the angle iron body through the cutting component. And when the cutting component cuts the angle iron body, the angle iron body stops. Move the angle iron body intermittently to cut the angle iron body into multiple angle iron bodies of the same length. Among them, identify the steel stamp number on the angle steel through the vision system and cut it according to the corresponding drawing program.

[0022] Step 3: After the previous angle iron body is cut, drive the output end of the driving motor to rotate in the reverse direction. Drive the rotating screw rod to rotate in the reverse direction through the rotating shaft, and drive the installation shaft to rotate through the locked connecting component through the rotating shaft, and drive the sprocket to rotate through the installation shaft, so that the sprocket drives the placing table in the middle to move away, and drives the placing table at the rear with the angle iron body placed on it to move to the middle. When the angle iron body moves to the middle, the connecting component is unlocked. At this time, the rotating shaft cannot drive the installation shaft to rotate through the connecting component, and the rotating screw rod continues to rotate, so that the screw sleeve drives the moving plate to reset, and guides the moving plate through the guiding sleeve and the guiding rod, so that the moving plate drives the pushing block to reset through the telescopic cylinder, and at the same time, the telescopic cylinder drives the pushing block to move upward to reset.

[0023] Step 4: Push the angle iron body that has moved to the middle to the right, so that the angle iron body enters the cutting component, push out the remaining angle iron body from the cutting component after the previous cut, and cut the next angle iron body.

[0024] Compared with the prior art, the present invention provides a cutting device for processing power tower components and its usage method, which has the following beneficial effects:

[0025] 1. For the cutting device for processing power tower components and its usage method, the driving motor drives the rotating shaft to drive the screw rod to rotate, so that the screw sleeve drives the pushing block to push the angle iron body into the cutting device through the moving plate and the telescopic cylinder. During the reset process, the connecting component drives the installation shaft to rotate, so that the sprocket drives the transmission chain to move, so that the next placing table with the angle iron body moves to the feeding position. And during the cutting of the angle iron body, the uncut angle iron body is placed on the last placing table, so that the angle iron body can be continuously conveyed, reducing the stop time of the cutting device, so that more angle iron bodies can be cut in the same time, improving the use efficiency of the cutting device.

[0026] 2. For the cutting device for processing power tower components and its usage method, when the angle iron body moves on the top of the placing table, the angle iron body drives the metal ball to roll inside the installation hole and the limiting hole, avoiding the friction between the angle iron body and the placing table, thus avoiding the wear and damage of the angle iron body during the movement, keeping the angle iron body beautiful, avoiding the influence on its surface beauty caused by scratches during the feeding process of the angle iron body, and avoiding the subsequent need to remove the scratches on the surface of the angle iron body by polishing.

[0027] 3. For the cutting device for processing power tower components and its usage method, when the angle iron body moves, it drives the conveying round shaft to rotate inside the fixed seat through the bearing, thus facilitating the support of the angle iron body, avoiding the bending of the angle iron body during the process, ensuring that the angle iron body can accurately enter the cutting component, and limiting the angle iron body through the limiting round plate, avoiding the inclination of the angle iron body during the conveying process, resulting in the angle iron body being unable to enter the cutting component.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a cutting device for processing tower components of power transmission towers and its usage method.

[0042] In a typical embodiment of the present application, as Figures 1-4 shown, a cutting device for processing tower components of a power transmission tower includes:

[0043] An installation base 1, with an installation frame 2 fixedly arranged on the left side of the installation base 1, a fixing plate 3 fixedly arranged on the left side of the installation frame 2, a driving motor 4 fixedly arranged on the left side of the fixing plate 3, a rotating shaft 5 fixedly arranged at the output end of the driving motor 4, a rotating screw 6 fixedly arranged at the right end of the rotating shaft 5, a screw sleeve 7 threadedly arranged on the surface of the rotating screw 6, a moving plate 8 fixedly arranged at the top of the screw sleeve 7, a guiding sleeve 9 fixedly arranged at the bottom of the moving plate 8, guiding sliding sleeves fixedly arranged between the opposite surfaces of the screw sleeve 7 and the guiding sleeve 9, a guiding sliding rail slidably arranged inside the guiding sliding sleeve, and the guiding sliding rail fixedly installed on the installation frame 2, which is convenient for sharing the forces on the rotating screw 6 and the guiding rod 10, avoiding excessive bending of the rotating screw 6 and the guiding rod 10 due to excessive force. A guiding rod 10 is slidably arranged on the surface of the guiding sleeve 9, a telescopic cylinder 11 is fixedly arranged at the top of the moving plate 8, a pushing block 12 is fixedly arranged at the output end of the telescopic cylinder 11, an installation shaft 14 is rotatably arranged inside the installation frame 2, a sprocket 15 is fixedly arranged on the surface of the installation shaft 14, a transmission chain 16 is meshed on the surface of the sprocket 15, placing platforms 17 are fixedly arranged on both the upper and lower sides of the transmission chain 16, an angle iron body 18 is lapped on the surface of the placing platform 17, a conveying shaft 19 is fixedly arranged on the top of the installation base 1. The driving motor 4 drives the rotating shaft 5 to drive the rotating screw 6 to rotate, causing the screw sleeve 7 to drive the moving plate 8 to move to the right, and guiding the moving direction of the moving plate 8 through the guiding sleeve 9 and the guiding rod 10. The moving plate 8 drives the pushing block 12 to drive the angle iron body 18 to move through the telescopic cylinder 11, thus facilitating the feeding of the angle iron body 18.

[0044] A connecting component 13, which is arranged on the left side of the installation frame 2 and is used for the rotating shaft 5 to drive the installation shaft 14 to rotate. Through the connecting component 13, the rotation of the installation shaft 14 can be controlled by driving the rotating shaft 5, thus facilitating the installation shaft 14 to drive the sprocket 15 to rotate, and facilitating the transmission chain 16 to drive the angle iron body 18 to move through the placing platform 17, so as to facilitate the movement of the angle iron body 18 to the feeding position. And after the angle iron body 18 moves to the feeding position, the rotation of the installation shaft 14 can be controlled not to be driven by the rotating shaft 5, so that the transmission chain 16 and the placing platform 17 stop, thus facilitating the angle iron body 18 to stop at the feeding position.

[0045] A cutting component 20, which is arranged on the top of the installation base 1 and is used for cutting the angle iron body 18. Through the cutting component 20, it is convenient to cut the angle iron body 18, so as to facilitate cutting the angle iron body 18 into a suitable length.

[0046] As a preferred embodiment in this example, referring to Figures 5 to 8As shown, a driving pulley 131 is fixedly installed on the surface of a rotating shaft 5 on the surface of a connecting component 13. A transmission belt 132 is meshed inside the driving pulley 131. A driven pulley 134 is meshed inside the transmission belt 132. A rotating ring 135 is fixedly arranged on the left side of the driven pulley 134. A limiting ring 133 is fixedly arranged on the outer surface of the rotating ring 135. A limiting circular ring 136 is rotatably arranged on the surface of the rotating ring 135. A circular groove is formed inside the limiting circular ring 136. The limiting ring 133 is slidably arranged inside the circular groove. The limiting ring 133 is a metal circular ring. The circular groove facilitates the installation of the limiting ring 133, thereby facilitating the limitation of the position of the rotating ring 135, enabling the limiting circular ring 136 to limit the driven pulley 134. The limiting circular ring 136 is fixedly installed on the left side of the mounting frame 2. A belt rotating ring 137 is fixedly arranged inside the driven pulley 134. A triangular groove is formed inside the belt rotating ring 137. The number of the triangular grooves is several and they are distributed in a circular array. The longitudinal section of the connecting block 1312 is triangular. The triangular groove and the triangular connecting block 1312 cooperate to facilitate the insertion of the connecting block 1312 into the belt rotating ring 137 and also facilitate the removal of the connecting block 1312 from the belt rotating ring 137. A rotating sleeve 138 is arranged inside the belt rotating ring 137. A mounting sleeve 139 is fixedly arranged inside the rotating sleeve 138. A moving piston 1310 is slidably arranged inside the mounting sleeve 139. A moving rod 1311 is fixedly arranged inside the moving piston 1310. One end of the moving rod 1311 is fixedly provided with a connecting block 1312. The surface of the connecting block 1312 abuts against the inner wall of the belt rotating ring 137. The other end of the moving rod 1311 is fixedly provided with a hemispherical convex block 1314. A spring 1313 is connected between the side surface of the moving piston 1310 and the inner wall of the mounting sleeve 139. A rotating shaft 1317 is fixedly arranged inside the rotating sleeve 138. The rotating shaft 1317 is fixedly installed at the left end of the mounting shaft 14. A pushing sleeve 1315 is lapped on the surface of the rotating shaft 1317. The left end of the pushing sleeve 1315 is a conical surface. The inner diameter of the pushing sleeve 1315 is the same as the diameter of the rotating shaft 1317. An installation groove for installing a bearing and an electric push rod 1316 is formed at the left end of the pushing sleeve 1315, facilitating the pushing sleeve 1315 to push the hemispherical convex block 1314 to move, thereby facilitating the hemispherical convex block 1314 to push the moving rod 1311 to move, enabling the moving rod 1311 to push the connecting block 1312 to insert into the belt rotating ring 137. The outer surface of the pushing sleeve 1315 abuts against the surface of the hemispherical convex block 1314. An electric push rod 1316 is arranged on the left side of the pushing sleeve 1315. The output end of the electric push rod 1316 is fixedly installed inside the pushing sleeve 1315, and the pushing sleeve 1315 is fixedly installed on the left side of the fixing plate 3. The electric push rod 1316 drives the pushing sleeve 1315 to separate from the hemispherical convex block 1314. The spring 1313 drives the moving rod 1311 to approach the rotating shaft 1317 through the moving piston 1310, enabling the hemispherical convex block 1314 to contact the rotating shaft 1317, causing the connecting block 1312 to move out of the belt rotating ring 137.The rotating shaft 5 cannot drive the mounting shaft 14 to rotate through the connecting component 13, making the transmission chain 16 uncertain. When it is necessary to load the next angle iron body 18, the electric push rod 1316 pushes the hemispherical convex block 1314 upward through the push sleeve 1315, causing the moving rod 1311 to drive the moving piston 1310 and the connecting block 1312 to move, so that the connecting block 1312 is inserted into the inside of the belt rotating ring 137. At the same time, the moving piston 1310 stretches the spring 1313. At this time, the rotating shaft 5 can drive the mounting shaft 14 to rotate through the connecting component 13, and the mounting shaft 14 drives the sprocket 15 to rotate, so that the transmission chain 16 moves the next angle iron body 18 to the middle position of the mounting frame 2 through the placing table 17. And when the pushing block 12 moves to the left and resets, the next angle iron body 18 can be moved to the loading position. After the pushing block 12 resets, the angle iron body 18 can be loaded, reducing the time consumed in the loading process of the angle iron body 18.,

[0047] As a preferred implementation manner in this embodiment, refer to Figure 11 As shown in the figure, the cutting component 20 includes a U-shaped plate 201 fixedly installed on the top of the mounting base 1. A hydraulic push rod 202 is fixedly arranged on the top of the U-shaped plate 201. The output end of the hydraulic push rod 202 is installed with a mounting plate 203 through bolts. A guide plate 204 is slidably arranged inside the mounting plate 203. The guide plate 204 is fixedly installed inside the U-shaped plate 201. A cutting knife 205 is fixedly arranged inside the mounting plate 203. A cutting table 206 is arranged inside the U-shaped plate 201. The cutting table 206 is fixedly installed on the top of the mounting base 1. The output end of the hydraulic push rod 202 pushes the mounting plate 203 downward through bolts and guides the mounting plate 203 through the guide plate 204, so that the mounting plate 203 pushes the cutting knife 205 to cut the angle iron body 18, facilitating the cutting of the angle iron body 18 and keeping the cut of the angle iron body 18 vertical, avoiding errors in the cut of the angle iron body 18.

[0048] As a preferred implementation manner in this embodiment, refer to Figure 9 As shown in the figure, the placing table 17 includes a triangular table 171. The triangular table 171 is fixedly installed on the surface of the transmission chain 16. Mounting holes 172 are formed on the inclined surface of the triangular table 171. Metal balls 173 are lapped inside the mounting holes 172. A limiting plate 174 is fixedly arranged on the surface of the triangular table 171. Limiting holes 175 penetrate through the inclined surface of the limiting plate 174. The inner wall of the limiting hole 175 is lapped with the surface of the metal ball 173. When the angle iron body 18 moves on the surface of the placing table 17, the angle iron body 18 drives the metal ball 173 to rotate inside the mounting hole 172 and the limiting hole 175, thus avoiding friction between the placing table 17 and the angle iron body 18, preventing wear of the angle iron body 18, and facilitating the protection of the angle iron body 18.

[0049] As a preferred implementation manner in this embodiment, refer to Figure 10 As shown, the conveying shaft 19 includes a fixed seat 191 fixedly installed on the top of the installation base 1. A conveying circular shaft 192 is installed inside the fixed seat 191 through a bearing. A limiting circular plate 193 is fixedly arranged on the surface of the conveying circular shaft 192. When the angle iron body 18 enters the conveying shaft 19, the angle iron body 18 is supported by the conveying circular shaft 192, and the conveying circular shaft 192 can rotate inside the fixed seat 191 through the bearing, thereby avoiding friction between the angle iron body 18 and the conveying circular shaft 192. Moreover, the limiting circular plate 193 contacts the angle iron body 18, and can move the moving direction of the angle iron body 18, so that the angle iron body 18 can accurately enter the cutting component 20.

[0050] A usage method of a cutting device for processing tower components of a power transmission tower includes the following steps:

[0051] Step 1: Place the angle iron body 18 of the power transmission tower on the two placing platforms 17 at the rear. Drive the output end of the telescopic cylinder 11 to push the pushing block 12 downward, so that the connecting component 13 is horizontally aligned with the angle iron body 18. Drive the output end of the driving motor 4 to drive the rotating shaft 5 to rotate. At this time, the rotating shaft 5 cannot drive the installation shaft 14 to rotate through the connecting component 13, and drive the rotating screw 6 to rotate through the rotating shaft 5. The screw sleeve 7 drives the moving plate 8 to move to the right, and drives the guiding sleeve 9 to slide on the surface of the guiding rod 10 through the moving plate 8, so that the moving plate 8 drives the pushing block 12 to push the angle iron body 18 to move to the right through the telescopic cylinder 11;

[0052] Step 2: When the angle iron body 18 moves into the conveying shaft 19, and the position of the angle iron body 18 is limited by the conveying shaft 19, so that the angle iron body 18 enters the cutting component 20, and the cutting component 20 cuts the angle iron body 18. Moreover, when the cutting component 20 cuts the angle iron body 18, the angle iron body 18 stops. By intermittently moving the angle iron body 18, the angle iron body 18 is cut into multiple angle iron bodies 18 of the same length. Among them, the steel stamp number on the angle steel is identified through the vision system, and the cutting is carried out according to the corresponding drawing program;

[0053] Step 3: After the cutting of the previous angle iron body 18 is completed, the driving motor 4 drives the output end to rotate in the reverse direction, drives the rotating screw 6 to reverse through the rotating shaft 5, and the rotating shaft 5 drives the mounting shaft 14 to rotate through the locked connecting member 13, and drives the sprocket 15 to rotate through the mounting shaft 14, so that the sprocket 15 drives the placing table 17 in the middle to move away, and drives the placing table 17 at the rear where the angle iron body 18 is placed to move to the middle. When the angle iron body 18 moves to the middle, the connecting member 13 is unlocked. At this time, the rotating shaft 5 cannot drive the mounting shaft 14 to rotate through the connecting member 13, while the rotating screw 6 continues to rotate, so that the screw sleeve 7 drives the moving plate 8 to reset, and guides the moving plate 8 through the guide sleeve 9 and the guide rod 10, so that the moving plate 8 drives the pushing block 12 to reset through the telescopic cylinder 11. At the same time, the telescopic cylinder 11 drives the pushing block 12 to move upward and reset;

[0054] Step 4: Push the angle iron body 18 that has moved to the middle to the right, so that the angle iron body 18 enters the cutting member 20, push out the remaining angle iron body 18 from the last cutting from the cutting member 20, and cut the next angle iron body 18.

[0055] Working principle of the present invention: When in use, place the angle iron body 18 on the top of the metal ball 173. Drive the output end of the driving motor 4 to drive the rotating shaft 5 to rotate. At this time, drive the output end of the electric push rod 1316 to drive the push sleeve 1315 to move to the left, so that the push sleeve 1315 is separated from the hemispherical convex block 1314. Drive the moving piston 1310 to contract into the installation sleeve 139 through the elastic return of the spring 1313, and drive the moving rod 1311 to approach the rotating shaft 1317 through the moving piston 1310, so that the hemispherical convex block 1314 contacts the rotating shaft 1317. At this time, the moving rod 1311 drives the connecting block 1312 to move out of the belt rotating ring 137. The rotating shaft 5 drives the rotating screw 6 and the driving transmission wheel 131 to rotate at the same time. The driving transmission wheel 131 drives the driven transmission wheel 134 to rotate through the transmission belt 132. The driven transmission wheel 134 drives the limiting ring 133 and the rotating ring 135 to rotate inside the limiting circular ring 136. When the belt rotating ring 137 rotates, it cannot drive the connecting block 1312 to move, so that the rotating shaft 1317 does not rotate. The screw sleeve 7 drives the left side of the moving plate 8 to move, and drives the guide sleeve 9 to slide on the surface of the guide rod 10 through the moving plate 8, so that the moving plate 8 drives the push block 12 to move to the left through the telescopic cylinder 11, and pushes the angle iron body 18 to move to the left through the push block 12. When the angle iron body 18 moves, it drives the metal ball 173 to roll inside the installation hole 172 and the limiting hole 175, so that the angle iron body 18 moves to the top of the conveying round shaft 192. The limiting circular plate 193 contacts the front and rear sides of the angle iron body 18, and limits the angle iron body 18 through the limiting circular plate 193. When the angle iron body 18 moves to the top of the cutting table 206 and passes through the U-shaped plate 201. When the angle iron body 18 reaches the cutting length, drive the output end of the hydraulic push rod 202 to extend, so that the output end of the hydraulic push rod 202 pushes the installation plate 203 to move downward through the bolt, and guides the moving direction of the installation plate 203 through the guide plate 204, so that the installation plate 203 moves in the vertical direction, so that the installation plate 203 pushes the cutting knife 205 to cut the angle iron body 18. After the cutting of the previous angle iron body 18 is completed, the telescopic cylinder 11 drives the output end to drive the push block 12 to move upward to reset. The driving motor 4 drives the output end to drive the rotating shaft 5 to reverse. At this time, the electric push rod 1316 drives the output end to push the push sleeve 1315 into the rotating sleeve 138. Push the hemispherical convex block 1314 to move upward through the conical surface of the push sleeve 1315, so that the hemispherical convex block 1314 pushes the moving rod 1311 to move, and drives the moving piston 1310 and the connecting block 1312 to move through the moving rod 1311, so that the connecting block 1312 is inserted into the belt rotating ring 137. At the same time, the moving piston 1310 stretches the spring 1313. The rotating shaft 5 drives the rotating screw 6 and the driving transmission wheel 131 to rotate, so that the driving transmission wheel 131 drives the driven transmission wheel 134 to rotate through the transmission belt 132.The driven transmission wheel 134 drives the belt rotating ring 137 to rotate, and drives the connecting block 1312 to move through the belt rotating ring 137, drives the moving rod 1311 to move through the connecting block 1312, so that the moving rod 1311 drives the mounting sleeve 139 to move through the moving piston 1310, drives the rotating sleeve 138 to rotate through the mounting sleeve 139, drives the rotating shaft 1317 to rotate through the rotating sleeve 138, so that the belt rotating ring 137 drives the mounting shaft 14 to rotate, the mounting shaft 14 drives the sprocket 15 to rotate, so that the transmission chain 16 drives the placing table 17 to move, and drives the angle iron body 18 to move through the placing table 17, so that the next angle iron body 18 moves to the middle position of the mounting frame 2. At this time, the electric push rod 1316 drives the pushing sleeve 1315 to move out of the rotating sleeve 138, so that the spring 1313 drives the moving piston 1310 to contract into the mounting sleeve 139, and drives the moving rod 1311 to approach the rotating shaft 1317 through the moving piston 1310, so that the moving rod 1311 drives the connecting block 1312 to move out of the belt rotating ring 137, and the hemispherical convex block 1314 contacts the rotating shaft 1317. At this time, the belt rotating ring 137 cannot drive the connecting block 1312 to move, so that the rotating shaft 1317 does not rotate, the mounting shaft 14 and the sprocket 15 do not rotate, so that the transmission chain 16 does not drive the placing table 17 to move, and the angle iron body 18 does not move any more. And the rotating screw 6 continues to rotate, the screw sleeve 7 drives the moving plate 8 to reset, and guides the moving plate 8 through the guide sleeve 9 and the guide rod 10, so that the moving plate 8 drives the pushing block 12 to reset through the telescopic cylinder 11, and the output end of the telescopic cylinder 11 drives the pushing block 12 to move downward, so as to push the next angle iron body 18 to move to the left, so that the next angle iron body 18 enters the cutting member 20, and pushes the remaining angle iron bodies 18 in the cutting member 20 out through the angle iron body 18, so as to cut the next angle iron body 18, and continuous feeding and conveying of the angle iron body 18 can be carried out.
