Technical Field
[0001] This invention relates to the field of angle steel cutting machinery technology, specifically to a high-efficiency cutting device for angle steel production. Background Technology
[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. It belongs to the category of economical cross-section profiles and is divided into two main categories: equal-sided angle steel and unequal-sided angle steel. It is one of the most commonly used profiles in steel structures, supports, and frames.
[0003] Cutting the ends of angle steel into arcs is a common angle steel processing technique. Current technology involves directly cutting the angle steel end close to the cutting equipment. After cutting one side of the end, the angle steel needs to be rotated and flipped before cutting the other side. This method is inconvenient due to the overall length of the angle steel, making it difficult to operate manually. Furthermore, the horizontal angle between the angle steel end and the cutting point cannot be precisely maintained during positioning, resulting in asymmetry between the two arc surfaces of the cut end, which affects subsequent installation and use. Therefore, we propose a high-efficiency cutting device for angle steel production to address these shortcomings. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figures 1 to 7 The present invention provides a technical solution: including an operating table 1, the surface of which is provided with an installation groove 101, and the operating table 1 is respectively provided with a cutting mechanism 2, a conversion mechanism 3, a positioning mechanism 4 and a flipping mechanism 5;
[0034] The cutting mechanism 2 includes a mounting frame 201 disposed on one side of the operating table 1. A contact plate 202 is driven on the mounting frame 201. A cutting seat 203 is disposed below the contact plate 202. A cutting groove 204 is annularly opened on the cutting seat 203 near the lower part of the contact plate 202. Support arms 205 are fixedly connected to both sides of the contact plate 202. The center point of the support arm 205 is located at the two included angles of the contact plate 202. One end of the laser cutting head 206 is driven at the center of the support arm 205. The other end of the laser cutting head 206 is slidably connected to the contact plate 202.
[0035] In this embodiment, after the angle steel is positioned, the contact plate 202 is moved downward by the mounting bracket 201. The contact plate 202 drives the laser cutting head 206 to move downward and approach the angle steel. After the contact plate 202 contacts the angle steel, it stops moving. Then, the laser cutting head 206 is started to cut the angle steel in an arc. The laser cutting head 206 slides around the center of the support arm 205 as the axis point and around the track on the contact plate 202. The movement trajectory of the laser cutting head 206 is an arc, which is adapted to the arc of the angle steel to be cut. After the cutting is completed, one side of the end of the angle steel is cut into an arc shape.
[0036] The conversion mechanism 3 includes a support plate 301 that is slidably disposed in the mounting groove 101. A side arm 302 is fixedly connected to the side of the support plate 301. The end of the side arm 302 away from the support plate 301 is rotatably connected to the operating table 1. A drive motor 303 is provided at the top of the connection between the side arm 302 and the operating table 1. The drive motor 303 is used to drive the side arm 302 to rotate.
[0037] The positioning mechanism 4 includes a connecting arm 401, with an outer corner bracket 402 symmetrically and fixedly connected to both sides of the connecting arm 401, and an inner corner bracket 403 fixedly connected to the inner side of the outer corner bracket 402, forming a gap between the outer corner bracket 402 and the inner corner bracket 403.
[0038] A pressure roller 404 is provided diagonally on the inner corner frame 403. The pressure roller 404 is elastically connected to the inner corner frame 403. The top of the pressure roller 404 abuts against a wedge plate 405. The wedge plate 405 is elastically connected to the inner corner frame 403.
[0039] One of the outer corner brackets 402 is fixedly connected to a side box 406. A through slot 407 is provided through the side box 406, which is adapted to the gap between the outer corner bracket 402 and the inner corner bracket 403.
[0040] The side box 406 has a drive slide rail 408 arranged diagonally inside. A positioning head 409 is driven on the drive slide rail 408. The shape of the end of the positioning head 409 is adapted to the shape of the middle part of the slot 407. A trigger roller 410 is symmetrically installed on one side of the positioning head 409.
[0041] Inside the side box 406, rotating rods 411 are rotatably arranged on both sides of the drive slide rail 408. A torsion spring 412 is provided at the connection between the rotating rods 411 and the side box 406. The other end of the rotating rods 411 is rotatably arranged on an outer corner bracket 402 away from the side box 406.
[0042] A curved plate 413 is provided on the rotating rod 411 near the torsion spring 412. The curved plate 413 abuts against the trigger roller 410. A pressing plate 414 is also fixedly installed on the rotating rod 411. The surface of the pressing plate 414 is curved. The pressing plate 414 abuts against the wedge plate 405.
[0043] In this embodiment, the angle steel to be cut is passed through the through slot 407 and placed in the gap between the outer angle bracket 402 and the inner angle bracket 403, so that the outer wall of the angle steel is in contact with the outer angle bracket 402 and the inner wall of the angle steel is not in contact with the inner angle bracket 403. The position of the angle steel is adjusted so that the end of the angle steel is located between the cutting seat 203 and the contact plate 202.
[0044] In this embodiment, the drive slide rail 408 is activated, and the drive slide rail 408 drives the positioning head 409 to slide along the drive slide rail 408. The end of the positioning head 409 is in contact with the inner surface of the angle steel to achieve the initial positioning of the angle steel. When the positioning head 409 moves, the trigger roller 410 on one side moves synchronously, squeezing the curved plate 413 and driving the rotating rod 411 to overcome the elastic force of the torsion spring 412 and rotate around the side box 406 and the outer corner frame 402.
[0045] In this embodiment, when the rotating rod 411 rotates, the pressing plate 414 on it rotates synchronously, pressing the wedge plate 405, causing the wedge plate 405 to slide outward along the inner angle frame 403, and pressing the pressure roller 404. Since the pressure roller 404 is elastically connected to the inner angle frame 403, it tightly abuts against the inner wall of the angle steel after being pressed. In conjunction with the outer angle frame 402 and the positioning head 409, the angle steel is locked and fixed from the inside, outside and side directions, ensuring that the angle steel does not shift or shake during the cutting process.
[0046] The flipping mechanism 5 includes a switching plate 501 that is slidably connected to the support plate 301. A connecting arm 401 is rotatably provided on the top of the switching plate 501. Angle brackets 502 are fixedly connected to the middle of both sides of the switching plate 501. An electric cylinder 503 is provided on the side of the angle bracket 502. The output shaft end of the electric cylinder 503 is fixedly connected to the angle bracket 502.
[0047] A through-hole 504 is provided in the middle of the switching plate 501, and a trigger plate 505 is fixedly connected to the connecting arm 401. The trigger plate 505 is set at an angle.
[0048] The side of the trigger plate 505 abuts against the stop bar 506, the stop bar 506 is fixedly connected to the support plate 301, and the two sides of the stop bar 506 are provided with support frames 507, which are used to support the switching plate 501.
[0049] In this embodiment, after one side of the angle steel end is cut, the contact plate 202 drives the laser cutting head 206 to rise, and then controls the electric cylinder 503 to push the switching plate 501 to slide along the support plate 301 to the other side. During the process, when the outer angle frame 402 moves, the trigger plate 505 connected in its middle is blocked by the stop bar 506, causing the trigger plate 505 to drive the outer angle frame 402 to flip. The other side of the outer angle frame 402 contacts the switching plate 501, causing the angle steel installed on the outer angle frame 402 and the inner angle frame 403 to be flipped. At this time, the angle steel end The side of the head that has been cut is in an upright position, and the side that has not been cut is in a horizontal position. At this time, the conversion mechanism 3 is activated, the drive motor 303 drives the side arm 302 to run, and the support plate 301 rotates ninety degrees around the mounting groove 101, so that the angle steel moves from one side of the cutting seat 203 to the other side, so that the end of the angle steel is rotated and aligned again between the cutting seat 203 and the contact plate 202. At this time, the contact plate 202 is activated to press down, and the laser cutting head 206 cuts the end of the angle steel again and cuts the arc on the side of the angle steel that has not been cut.
[0050] The method of use and advantages of this invention: The working principle of this high-efficiency cutting device for angle steel production is as follows:
[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown:
[0052] S1: After the angle steel is placed into the gap between the inner and outer angle brackets 402, the positioning head 409 is driven by the drive slide rail 408 to complete the initial positioning on the inner side. When the positioning head 409 moves, the trigger roller 410 squeezes the curved plate 413, which drives the rotating rod 411 to rotate against the torsion spring 412. The squeezing plate 414 pushes the wedge panel 405 at the same time, so that the elastic pressure roller 404 presses the inner wall of the angle steel. Together with the outer angle bracket 402 and the positioning head 409, the three sides are automatically clamped to ensure that there is no movement during cutting.
[0053] S2: After the contact plate 202 is pressed down and positioned against the top surface of the angle steel, the laser cutting head 206 slides in an arc along the track of the contact plate 202 with the center of the support arm 205 as the fulcrum of rotation, and outputs an arc-shaped cutting trajectory that matches the end of the angle steel to complete the single-sided arc cutting edge.
[0054] S3: The electric cylinder 503 pushes the switching plate 501 to move horizontally. The trigger plate 505 is limited by the stop rod 506, which drives the positioning mechanism 4 and the angle steel to rotate as a whole, realizing the reversal of the cutting surface. The conversion mechanism 3 drives the support plate 301 to rotate through the drive motor 303 and the side arm 302, and moves the angle steel to the cutting station. The laser cutting head 206 repeats the arc movement to complete the arc cutting on the other side of the angle steel, realizing double-sided arc cutting in one clamping.
[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
