Description

Technical Field

[0001] The present invention relates to the technical field of steel cutting and processing, and specifically to an automatic cutting device for steel profiles. Background Art

[0002] As a key device in modern industrial manufacturing, the automatic cutting device is widely used in the field of metal processing. It replaces manual operation through mechanical automation, significantly improving the cutting efficiency and precision of materials. In the manufacturing of steel cutting equipment, the precise cutting of steel profiles is the core link to ensure the structural strength and assembly precision of products, especially posing higher technical requirements for the batch processing of profiles with special-shaped cross-sections.

[0003] The existing steel profile cutting devices usually consist of a fixed platform, a cutting tool, and a driving mechanism. Specifically, traditional equipment fixes the steel by a manual or semi-automatic clamping mechanism, applying pressure to the workpiece in a single-point or linear clamping manner. The cutting tools are mostly fixed disc cutters or reciprocating saw blades, driven by a motor to complete linear or rotary cutting operations.

[0004] Although the cutting devices in the prior art can already achieve basic cutting functions, there are still certain deficiencies in some equipment. The clamping methods of traditional equipment mostly use unidirectional rigid clamping or mechanical screw adjustment, with uneven clamping force distribution. Especially for thin-walled profiles or workpieces with special-shaped cross-sections, it is easy to cause local stress concentration, resulting in workpiece deformation, surface scratches, or even fracture during the cutting process. In addition, the metal chips generated by some equipment naturally fall under the workbench by gravity or directly accumulate inside the equipment, requiring manual cleaning at regular intervals. Moreover, the ferromagnetic and non-ferromagnetic chips are mixed, and the sorting process is cumbersome and the recycling efficiency is low. In addition, the existing equipment lacks a certain automatic cleaning function, and the accumulation of cutting chips will result in a large manual cleaning intensity after the work is completed, affecting the continuous production efficiency.

[0005] Therefore, the present invention proposes an automatic cutting device for steel profiles to solve the deficiencies in the prior art. Summary of the Invention

[0028] Please refer to the attached Figure 3 and the attached Figure 9 , the cleaning mechanism 6 includes a protective shell 601, the protective shell 601 is fixed on the top of the connecting beam 13, a second electric push rod 602 is arranged at the rear side inside the protective shell 601, a receiving plate 603 is fixed at the bottom of the second electric push rod 602, a scraping plate 607 slides inside the receiving plate 603, a plurality of first damping rods 604 which are evenly distributed in a horizontal straight line are fixed at the top of the scraping plate 607 close to the receiving plate 603, limiting blocks 605 are fixed on both the left and right sides of the scraping plate 607, limiting grooves 606 are opened on both the left and right sides inside the receiving plate 603, and the two limiting blocks 605 are respectively slidably connected inside the two limiting grooves 606.

[0029] Specifically, the protective shell 601 is made of aluminum alloy and fixed on the top of the connecting beam 13 to protect the internal parts. The second electric push rod 602 is the same DC electric push rod as the first electric push rod 402, which drives the receiving plate 603 to move in the vertical direction. The receiving plate 603 is connected to the polyurethane scraping plate 607 through an internal sliding pair. The surface of the scraping plate 607 is provided with a wear-resistant corrugated structure for removing the cutting debris on the surface of the placing plate 16. The plurality of first damping rods 604 are distributed in a horizontal array, providing a supporting force for the scraping plate 607 through spring damping to ensure that the scraping plate 607 adaptively fits the surface of the placing plate 16. The limiting blocks 605 and the limiting grooves 606 adopt a clearance fit to limit the vertical movement range of the scraping plate 607, prevent deviation and maintain the cleaning track accuracy.

[0030] Please refer to the attached Figure 4 , the supporting assembly 5 includes a third electric push rod 501, the third electric push rod 501 is fixed inside the placing plate 16, an integrated block 502 is fixed at the top of the third electric push rod 501, a supporting plate 504 is slidably connected to the top side inside the integrated block 502, and a plurality of second damping rods 503 which are evenly distributed in a horizontal straight line are fixed at the bottom of the supporting plate 504.

[0031] Specifically, the third electric push rod 501 is the same DC electric push rod as the second electric push rod 602 and the first electric push rod 402, and is vertically fixed inside the placing plate 16.

The second damping rods 503 horizontally arrayed at the bottom of the supporting plate 504 are used to suppress the cutting vibration and prevent the profile from deforming to ensure the stability of the workpiece during cutting.

[0032] Please refer to the attached Figure 7, the screening component 2 includes a screening plate 206 which is slidably connected to the inner top side of the control box 1. A connecting block 205 is fixed to the rear side of the screening plate 206. A swing arm 204 is rotatably arranged inside the connecting block 205. A rotating disk 203 is rotatably arranged at one end of the swing arm 204 away from the connecting block 205. A second transmission rod 202 is fixed to the bottom of the rotating disk 203. A second bevel gear 201 is fixed to one end of the second transmission rod 202 away from the rotating disk 203. The second bevel gear 201 meshes with the first bevel gear 302.

[0033] Specifically, the screening plate 206 is made of Q235 steel plate with surface hardening treatment and is slidably connected inside the control box 1. The connecting block 205 is made of cast iron and is fixed to the rear side of the screening plate 206. The swing arm 204 is connected inside through a bearing. The swing arm 204 is forged from alloy steel and is used to transmit power, converting the rotational motion of the rotating disk 203 into the linear reciprocating motion of the screening plate 206. The rotating disk 203 is fixed to the top of the second transmission rod 202.

The second bevel gear 201 and the first bevel gear 302 are in meshing transmission, and the tooth surface is carburized and quenched, with a hardness of HRC58 - 62, achieving efficient power transmission.

[0034] Please refer to the appendix Figure 5 - appendix Figure 6 , the matching component 7 includes a matching block 701 which is fixed to one side of the first moving block 403 close to the second moving block 404. A matching groove 702 is formed inside the second moving block 404. The matching block 701 is slidably connected inside the matching groove 702.

[0035] Specifically, the matching block 701 is made of alloy steel and is fixed to the side surface of the first moving block 403. Its cross-section is trapezoidal in structure, forming a sliding pair with the matching groove 702 inside the second moving block 404. The matching groove 702 is treated by surface carburizing and quenching, converting the linear motion of the first moving block 403 into the vertical motion of the second moving block 404 through sliding fit.

[0036] Please refer to the appendix Figure 8 , the auxiliary component 8 includes a second motor 801 which is fixed inside the control box 1. A cleaning plate 802 is fixed to the output end of the second motor 801. The cleaning plate 802 is rotatably connected inside the control box 1. One end of the cleaning plate 802 abuts against the outer circumference of the magnetic separation drum 306.

[0037] Specifically, the second motor 801 uses a low-speed DC motor with a rated speed of 30 r / min and is fixed inside the control box 1. The cleaning plate 802 is fixed to its output end. After the second motor 801 is started, the cleaning plate 802 can be controlled to rotate. The cleaning plate 802 is made of polyurethane material with a thickness of 5 mm and a length matching the axial dimension of the magnetic separation drum 306. One end of it continuously abuts against the outer peripheral surface of the magnetic separation drum 306, and the adsorbed ferromagnetic debris is removed by the rotating scraping action.

[0038] Working principle: Before cutting the steel, first check whether all parts of the equipment are working properly, and then start the first electric push rod 402 inside the protective shell 401, so that the telescopic moving end of the first electric push rod 402 controls the moving block 403 to extend and move. During the process of the moving block 403 extending and moving, the upper and lower sides of the moving block 403 will respectively contact the opposite sides of the two moving blocks 404. Since the moving block 403 is an isosceles triangle, the shape of the moving block 404 is a right triangle, and the fitting block 701 and the fitting groove 702 are in sliding fit, so when the moving block 403 moves, the two moving blocks 404 will move in opposite directions accordingly. When the position of the moving block 404 changes, the clamping plate 406 connected by the connecting rod 405 will also change its position accordingly. After the two clamping plates 406 move to the limit position, the steel can be slid into the space between the two clamping plates 406, and then the first electric push rod 402 can be started again. The telescopic end of the first electric push rod 402 drives the moving block 403 to move away from the steel. At this time, the two moving blocks 404 move towards each other and then contact the upper and lower sides of the steel, thus fixing the steel. After the steel is fixed, the third electric push rod 501 can be started. The third electric push rod 501 drives the integrated block 502 to move upward until the support plate 504 contacts the bottom of the steel, which can provide a supporting force for the edge of the steel and avoid serious deformation of the steel caused by lack of support at the edge during the cutting of the steel. After the steel is fixed, according to the cutting size, adjust the positions of the two disc cutters 12. Then, by moving the electric slide 11, the disc cutters 12 can be moved to one end of the steel. After that, the disc cutters 12 can be started to cut the steel. The debris generated during the cutting process will fall on the surface of the placement plate 16 and the screening assembly 2. At this time, the first motor 301 can be started. By starting motor 1 - 301, motor 1 - 301 controls the rotation of bevel gear 1 - 302. Since bevel gear 1 - 302 meshes with bevel gear 2 - 201, when bevel gear 2 - 201 rotates, it will drive transmission rod 2 - 202 to rotate together. And transmission rod 2 - 202 will transmit the rotational motion to rotating disk 203. Then, rotating disk 203 controls swing arm 204 to swing inside control box 1. The connecting block 205 connected to the other end of swing arm 204 will correspondingly drive screening plate 206 to reciprocate inside control box 1, causing debris to fall into control box 1. While motor 1 - 301 controls the rotation of bevel gear 1 - 302, bevel gear 1 - 302 controls the rotation of cylindrical gear 1 - 304 through transmission rod 1 - 303. At this time, the cylindrical gears 2 - 305 meshing on the left and right sides of cylindrical gear 1 - 304 will rotate synchronously in the same direction. Then, magnetic separation drum 306 rotates. By using the rotation of magnetic separation drum 306 inside control box 1, the steel debris can be adsorbed and attached to the outer circumference of magnetic separation drum 306; After cutting is completed, take out the steel, start electric push rod 2 - 602, and make the telescopic end of electric push rod 2 - 602 control receiving plate 603 to move downward. At this time, receiving plate 603 drives scraper 607 to move until it contacts the surface of placing plate 16. Then, start electric slide 11, and make electric slide 11 move along cross - frame 9. Use scraper 607 to clean the surface of placing plate 16, and sweep the debris into control box 1. When scraper 607 moves and cleans the surface of placing plate 16, damping rod 1 - 604 will provide a supporting force for scraper 607, so that scraper 607 can always fit the surface of placing plate 16 and allow scraper 607 to slide to a certain extent inside receiving plate 603; When cutting non - ferromagnetic materials, the weakly magnetic material debris will directly fall into collection box 15. Thus, during multiple processing operations, ferromagnetic debris and non - ferromagnetic debris can be separated, reducing the difficulty of subsequent manual cleaning and collection of debris; After the work is completed, pull out collection box 15 containing non - magnetic debris from control box 1, replace it with a new collection box 15. Then, start motor 2 - 801, and control cleaning plate 802 to rotate inside magnetic separation drum 306 through motor 2 - 801, making the outer circumference of cleaning plate 802 contact the outer circumference of magnetic separation drum 306. Use cleaning plate 802 to scrape and collect the adsorbed debris. After all the work is completed, clean the equipment and conduct equipment inspections to ensure normal operation during the next work.
