Description

Technical Field

[0001] The invention relates to a cutting device, in particular to a cutting device for primary processing of steel plates. Background Art

[0002] Steel plate is a flat material made of steel. It has the characteristics of high strength, corrosion resistance and wear resistance. It is often used in construction, manufacturing, ships, bridges and automobiles. The thickness of the steel plate can vary according to the needs of use. Generally, there are thinner plates and thicker plates. Common steel plates include ordinary carbon steel plates, alloy steel plates, stainless steel plates and galvanized steel plates. Among them, steel plate cutting is a process of primary processing of steel plates, which is usually the process of cutting or splitting steel plates according to the required size. Steel plate disc knife cutting is a common processing method used to cut steel plates or workpieces into the required size to meet the manufacturing needs of subsequent processes.

[0003] For example, the patent with authorization announcement number CN220970970U discloses a fixed length cutting device for steel plate processing, including a workbench, a support plate fixedly installed on the upper side of the workbench, two cylinders fixedly installed on the front side of the support plate, a limit plate fixedly installed on the front end of the vertical slot shaft of the two cylinders, a material discharge trough opened on the workbench, a rotating motor fixedly installed on the upper side of the workbench, a cutting blade fixedly installed on the output shaft of the rotating motor, a mobile drive fixedly installed on the lower side of the workbench, and three mobile bars fixedly installed on the mobile drive. By inserting the plate to be cut into the mobile frame, the plate can be pushed backward so that the plate is against the limit plate. The spacing between the limit plate and the cutting blade can be adjusted by the cylinder, so that the length of the cut plate can be adjusted, and then the mobile drive can drive the mobile frame to move back and forth left and right after cutting, and the user only needs to push the plate backward after the plate is cut once.

An adjusting screw 702 is rotatably installed in the slide groove 701. The fixed-length baffle 7 is threadedly installed on the adjusting screw 702. The right end of the adjusting screw 702 extends to the outside of the horizontal platform 201 and is fixedly connected to the handwheel 703. The right side of the steel plate body is against the left side of the fixed-length baffle 7.

[0054] Specifically, a filter bucket 6 is detachably installed at the bottom of the horizontal platform 201, and the filter bucket 6 is located directly below the cut long hole. An external pipe 602 is fixedly connected to the bottom of the filter bucket 6. The external pipe 602 is used to discharge the used coolant and recycle it through an external recovery device. A filter net 601 is fixedly installed inside the filter bucket 6.

[0055] The specific implementation method of this embodiment is as follows: the steel plate body 1 to be processed is moved onto the horizontal surface 201, so that it passes through two side brackets 501, and the side brackets 501 limit it to prevent it from moving off, and the right side of the steel plate body 1 is against the fixed-length baffle 7, so that the position to be cut is located directly below the disc cutter 403;

[0056] When cutting the steel plate body 1, the driving motor 404 and the electric push rod work, the driving motor 404 drives the first gear 405 to rotate, the first gear 405 drives the second gear 406 to rotate, so that the rotating shaft 402 drives the disc cutter 403 to rotate, and the electric push rod drives the cutting equipment mounting plate 4 to move downward, and then the steel plate cutting assembly moves downward, so that the rotating disc cutter 403 cuts the steel plate body 1;

[0057] During the above-mentioned cutting process, the servo motor 305 works, which drives the propulsion screw 303 to rotate, so that the moving platform 304 moves in the through-length track 302, and the moving platform 303 moves together with the electric push rod, the cutting equipment mounting plate 4 and the steel plate cutting assembly, so that the rotating disc slicer 403 can perform linear movement cutting on the steel plate body 1, so that the right part of the steel plate body 1 can be completely cut off, the cutting is smoother, and the quality is guaranteed;

[0058] Before cutting, the hand wheel 703 is turned to rotate the adjusting screw 702, and then the fixed-length baffle 702 slides in the slide groove 701, so that the distance between the fixed-length baffle 7 and the cutting area changes, and the right side of the steel plate body 1 always contacts the fixed-length baffle 7, that is, the cutting length of the steel plate body 1 changes accordingly, thereby achieving the purpose of fixed-length cutting, which can be adjusted according to actual conditions and is suitable for the initial processing of steel plates with different length requirements;

[0059] When the electric push rod drives the cutting device mounting plate 4 to move downward, the guide roller 408 moves downward and squeezes the pressing plate 508. The pressing plate 508 drives the vertical slide bar 506 to move downward, so that the piston head 507 slides down in the liquid storage cylinder 502, so that the connecting pipeline 504 is connected with the nozzle 503, and then the coolant in the water storage tank 5 flows out to the cutting area, so that the coolant can be automatically added during cutting to improve the processing quality. When the disc cutter 403 moves to the bottom, it will realize linear movement cutting. During this period, the guide roller 408 always applies pressure on the pressing plate 508, so that the coolant can be continuously transported. When the cutting device mounting plate 4 moves linearly, the guide roller 408 will roll along the pressing plate 508 to reduce friction.

[0060] After the cutting is completed, the steel plate cutting equipment plate 4 is reset and moved upward until the guide roller 408 releases the force on the pressing plate 508. Under the elastic force of the compression spring 509, the piston head 507 in the liquid storage cylinder 502 moves upward, and the piston head 507 blocks the connection between the connecting pipe 504 and the nozzle 503 to make the connecting pipe 504 "closed", thereby realizing the blocking operation of the coolant. The coolant used in the cutting process flows into the filter bucket 6, and the filter net 601 blocks and collects the waste chips mixed in the coolant.
