Description

Technical Field

[0001] This utility model belongs to the field of iron tower angle steel production and processing technology, specifically, it relates to an iron tower angle steel corner cutting device. Background Technology

[0002] Angle steel cutting device for iron towers is a specialized piece of equipment used for cutting angle steel in the manufacture of iron towers. By precisely cutting the edges and corners of the angle steel, it meets the angle requirements of the connection points of the iron tower structure, ensuring the stability of the structure and the accuracy of installation.

[0003] The prior art discloses an efficient corner cutting device for iron tower angle steel workpieces (CN221848865U), which includes a processing table, a rotating shaft rotatably connected inside the processing table, a rotary table fixedly connected to the top of the rotating shaft, an electric push rod fixedly installed on the top of the rotary table, a lifting block fixedly connected to the output end of the electric push rod, a support rod rotatably connected to the side wall of the lifting block, a push block rotatably connected to the end of the support rod away from the lifting block, a clamping block fixedly connected to the top of the push block, a clamping seat fixedly connected to the top of the rotary table, a corner cutting assembly provided on the top of the processing table, and a drive assembly for rotating the rotating shaft provided inside the processing table.

[0004] Research revealed that existing technologies rely on manual assistance to flip the angle steel of the tower, which can easily lead to errors in precision and placement during manual flipping, resulting in problems with the cutting angle and affecting its use. Furthermore, existing technologies rely on a rotary table to directly rotate and adjust the cutting angle, lacking measures to limit the angle. This means that after the rotary table rotates, the angle of the tower angle steel cannot be precisely adjusted, resulting in a large error range in the angle adjustment range, making it difficult to meet the precision required for high-strength tower connections.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A corner cutting device for iron tower angle steel, including A processing table, wherein a rotary table is rotatably mounted on the top surface of the processing table, a mounting frame is fixedly mounted on one side of the top surface of the processing table, a cylinder is fixedly mounted on the top surface of the mounting frame, and a cutting blade is fixedly connected to the output end of the cylinder; The tilting and adjusting structure is movably mounted on the top surface of the rotary table. The tilting and adjusting structure includes a guide rail, a lead screw, a first support rod, a movable seat, a tilting frame, and a second support rod. The guide rail is fixedly mounted on the top surface of the rotary table, the lead screw is rotatably mounted on the top surface of the rotary table, the first support rod and the second support rod are both hinged to the rotary table, the tilting frame slides and rotates on the movable seat, and the movable seat is slidably mounted between the rotary table and the guide rail.

[0007] In a preferred embodiment of this utility model, a mounting frame is fixedly provided at the center of the top surface of the rotary table, and a servo motor is fixedly provided on one side of the mounting frame. The output end of the servo motor is connected to one end of a lead screw through a coupling, and the lead screw is rotatably mounted on the mounting frame.

[0008] In a preferred embodiment of this utility model, a movable block is threaded onto the lead screw, and the movable block is slidably disposed between the mounting frame and the lead screw. The first support rod and the second support rod are both hinged to the top surface of the mounting frame at the end away from the servo motor.

[0009] In a preferred embodiment of the present invention, the top surface of the movable block is hinged with a first connecting rod and a second connecting rod. The first connecting rod is hinged within the second connecting rod. A hinge seat is fixed on each side of the first and second supporting rods. The first supporting rod is hinged to the first connecting rod through the corresponding hinge seat, and the second supporting rod is hinged to the second connecting rod through the corresponding hinge seat.

[0010] In a preferred embodiment of this utility model, the guide rail has an arc-shaped structure, the movable seat has a T-shaped structure, and the movable seat is slidably fitted inside the guide rail.

[0011] In a preferred embodiment of this utility model, the top of the movable seat is provided with a T-shaped driving cavity, and a limiting slider is fixed on each side of the driving cavity. The flipping frame is an L-shaped gear structure, and an arc-shaped slide is provided on each side of the flipping frame. The limiting slider slides in the arc-shaped slide accordingly.

[0012] In a preferred embodiment of this utility model, the flipping frame is driven by a drive gear, which is rotatably disposed at the bottom of the drive cavity, and a magnetic block for magnetically fixing the angle steel is fixedly provided on the inner side plane of the flipping frame.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This device uses magnetic blocks to attract angle steel, avoiding deformation of the angle steel caused by local stress and displacement during the flipping process. The flipping frame is driven by the meshing of drive gears, and the sliding cooperation between the limit slider and the arc-shaped slide rail limits the flipping frame to rotate only along the arc-shaped trajectory without radial offset, thereby avoiding positional deviation during manual flipping and avoiding problems with the cutting angle due to flipping displacement, which would affect its use.

[0014] 2. After the rotary table drives the entire tilting and adjusting structure to change the initial angle, the screw 18 and the moving block 23 are threaded together to drive the hinged first and second connecting rods to change the hinge angle. The first and second connecting rods drive the corresponding first and second support rods to change their angles simultaneously. At this time, the angle between the first or second support rod and the central mounting frame is the angle of the chamfer. The semi-circular trajectory of the arc guide rail limits the sliding path of the moving seat 20, so that the angle steel always fits against the first or second support rod for a secondary angle change. Then, precise and detailed adjustments are made to refine the angle adjustment range of the chamfer, so that the device can meet the precision requirements of high-strength connection of the iron tower.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A corner cutting device for iron tower angle steel, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including A processing table 10 is provided with a rotating table 14 rotatably mounted on its top surface. A scale is coaxially mounted at the junction of the rotating table 14 and the processing table 10. The diameter of the scale is larger than that of the rotating table 14, which can be used by the user to determine the initial angle of the rotating table 14 after rotation. A mounting bracket 11 is fixedly mounted on one side of the top surface of the processing table 10. A cylinder 12 is fixedly mounted on the top surface of the mounting bracket 11 by bolts. A cutter 13 is fixedly connected to the output end of the cylinder 12 by a flange. The tilting and adjusting structure is movably mounted on the top surface of the rotary table 14. The tilting and adjusting structure includes a guide rail 16, a lead screw 18, a first support rod 19, a movable seat 20, a tilting frame 21, and a second support rod 24. The guide rail 16 is fixedly mounted on the top surface of the rotary table 14 by bolts. The lead screw 18 is rotatably mounted on the top surface of the rotary table 14. The first support rod 19 and the second support rod 24 are both hinged to the rotary table 14. The tilting frame 21 slides and rotates on the movable seat 20. The movable seat 20 is slidably mounted between the rotary table 14 and the guide rail 16.

[0020] It is worth noting that a rotating shaft is rotatably connected inside the processing table 10, and a rotary table 14 is fixedly connected to the top of the rotating shaft. A drive assembly for rotating the rotating shaft is installed inside the processing table 10. The drive assembly includes a drive motor fixedly installed inside the processing table 10, a worm gear fixedly connected to the output shaft of the drive motor, and a worm wheel fixedly connected to the worm gear drive on the outside of the rotating shaft. Starting the drive motor causes the worm gear to drive the worm wheel to rotate, thereby causing the rotating shaft to drive the rotary table to rotate, adjusting the position of the angle steel. The processing table 10 and the mounting bracket... 11. The specific connection methods and usage methods of each unit, including cylinder 12, cutter 13, rotary table 14 and drive assembly, are disclosed in detail in the prior art of an efficient corner cutting device for iron tower angle steel workpieces (CN221848865U). It is only necessary to ensure that the specifications are compatible with this device, so they will not be described in detail here. In use, the current cutting position and angle of the angle steel are controlled by the flipping and adjusting structure. The cylinder 12 is started, and the piston rod of the cylinder 12 drives the cutter 13 to cut the end of the angle steel fixed on the flipping frame 21.

[0021] like Figure 1 and Figure 2 As shown, a mounting frame 15 is fixedly provided at the center of the top surface of the rotary table 14, and a servo motor 17 is fixedly provided on one side of the mounting frame 15. The output end of the servo motor 17 is connected to one end of the lead screw 18 through a coupling. The servo motor 17 is connected to an external control panel for precisely outputting and controlling the rotational distance of the servo motor 17. The lead screw 18 is rotatably mounted on the mounting frame 15 through an angular contact ball bearing. like Figure 2 and Figure 3As shown, a movable block 23 is threaded onto the lead screw 18. The lead screw 18 is a precision ball screw, and the movable block 23 is made of cast iron. It has a ball nut that matches the lead screw 18 inside. The movable block 23 is slidably disposed between the mounting frame 15 and the lead screw 18. The first support rod 19 and the second support rod 24 are both hinged to the top surface of the mounting frame 15 away from the servo motor 17 through a hinge shaft. like Figure 3 and Figure 4 As shown, the top surface of the movable block 23 is hinged with a first connecting rod 26 and a second connecting rod 27. The first connecting rod 26 is hinged inside the second connecting rod 27. A hinge seat 25 is fixed on the adjacent side of the first support rod 19 and the second support rod 24. The first support rod 19 is hinged to the first connecting rod 26 through the corresponding hinge seat 25, and the second support rod 24 is hinged to the second connecting rod 27 through the corresponding hinge seat 25.

[0022] The working principle is as follows: according to the cutting angle requirements, the target angle mark is found on the scale on the top surface of the rotary table 14. Then, the rotary table 14 is driven to rotate to the initial angle by the drive motor. Then, the drive motor 17 is started, and the lead screw 18 rotates to drive the moving block 23 to move away from the drive motor 17 along the mounting frame 15. The moving block 23 pushes the first support rod 19 to rotate around its hinge point with the mounting frame 15 through the first connecting rod 26. At the same time, the second support rod 24 is pulled around its hinge point with the mounting frame 15 through the second connecting rod 27. At this time, the first support rod 19 and the second support rod 24 are rotating in opposite directions. At this time, the operator can select the first support rod 19 or the second support rod 24 that is suitable for the current cutting angle position according to the usage requirements. The angle steel to be cut is placed on the horizontal side of the flipping frame 21. The magnetic block 29 uses strong magnetic force to attract and fix the angle steel. After attraction, the angle steel does not loosen when gently shaken. The vertical side of the angle steel is in contact with the protrusion on the top surface of the first support rod 19 or the second support rod 24. At this time, the horizontal side of the angle steel is the current cutting angle position.

[0023] like Figure 3 As shown, the guide rail 16 is a precision-machined semi-circular arc structure. The surface of the guide rail 16 is subjected to high-frequency quenching treatment to reduce the wear of the moving seat 20 during long-term sliding. The moving seat 20 is a T-shaped structure and slides within the guide rail 16. like Figure 3 and Figure 5 As shown, the top of the movable seat 20 is provided with a T-shaped drive cavity 28, and a limiting slider 22 is fixed on each side of the drive cavity 28. The flipping frame 21 is an L-shaped gear structure. Specifically, the shape of the flipping frame 21 is a gear structure with a square groove inside. The two inner walls of the flipping frame 21 form an L-shaped cross section. The curved surface of the flipping frame 21 is a gear sawtooth surface. An arc-shaped slide is provided on each side of the flipping frame 21, and the limiting slider 22 slides in the arc-shaped slide accordingly. like Figure 5As shown, the drive gear 30 is rotatably mounted at the bottom of the drive cavity 28. The inner plane of the flipping frame 21 is fixed with a magnetic block 29 for magnetically fixing the angle steel. The flipping frame 21 drives the drive gear 30. A handwheel is fixed on one end of the drive gear 30 exposed on the movable seat 20. The rotation of the drive gear 30 can be controlled by the handwheel.

[0024] Specifically, when the angle steel is fixed first, the rotation and swing of the first support rod 19 and the second support rod 24, driven by the moving block 23, will synchronously push the moving seat 20 to slide along the guide rail 16. At this time, the moving seat 20 moves in coordination with the angle steel to change the cutting angle. When it is necessary to flip the angle steel and cut the vertical edge, the handwheel at the outer end of the drive gear 30 is manually turned. The handwheel drives the drive gear 30 to rotate. The rotating drive gear 30 meshes with the sawtooth side of the flipping frame 21, and the flipping frame 21 can rotate and flip at the top of the drive cavity 28. At this time, the limiting slider 22 in the drive cavity 28 of the moving seat 20 slides synchronously along the arc-shaped slide of the flipping frame 21 to cooperate. At this time, the flipping frame 21 drives the angle steel to flip, and the vertical edge of the angle steel becomes the horizontal edge so that the angle can be cut.
