Description

Technical Field

[0001] The present invention relates to the technical field of cutting settings, and specifically relates to a cutting device for processing high-precision cold-drawn steel. Background Technique

[0002] In the patent application with the publication number of CN215787060U, it includes a base. Four corners of the lower end of the base are fixedly installed with support columns, and fixed blocks are fixedly installed at the lower ends of the four support columns. A group of columns are fixedly installed at the left and right parts of the upper end of the base, and the two groups of columns are symmetrically distributed left and right. Chutes are opened between the two groups of columns. A support plate is fixedly installed in the middle of the upper end of the base. Fixators are fixedly installed at the four corners of the upper end of the base. A cutting groove is opened in the middle of the upper end of the support plate. An adjusting device is fixedly installed between the two groups of columns, and a cutting device is fixedly installed at the lower end of the adjusting device. The high-precision cutting machine for cutting steel plates described in the above patent can control the forward and backward movement of the cutting machine under the action of the adjusting device to improve the cutting effect, and then the steel plate can be limited by the limit block to improve the accuracy of the steel plate cut.

[0003] In the above patent, most steel plate cutting devices cannot clean the oil stains on the steel plate before cutting. During cutting, the oil stains and impurities will interfere with the contact between the saw blade and the steel plate, resulting in obvious traces and unevenness on the cutting surface. The oil stains and impurities will cause the saw blade to vibrate or deviate during cutting, thus affecting the cutting accuracy. The presence of oil stains and impurities will make the cutting resistance of the saw blade uneven, resulting in the saw blade shaking or deviating from the predetermined cutting path during cutting, increasing the dimensional deviation of the cut steel plate. And the presence of oil stains and impurities on the steel plate will affect the extrusion positioning of the steel plate. When the saw blade contacts the steel plate, a lateral force will be generated, causing the steel plate to shift horizontally during cutting, affecting the cutting accuracy. Most steel plate cutting settings cannot clean the debris by themselves after cutting, resulting in the accumulation of debris and affecting the cutting quality. Summary of the Invention

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) An extrusion assembly, a feeding assembly, and a slag collection assembly are arranged on the workbench. The moving assembly drives the extrusion assembly to descend, so that the preheating plate and the rotating roller extrude and position the steel plate, preventing the steel plate from sliding on the workbench due to the lateral force when contacting the circular saw cutting machine during the cutting process, causing the steel plate to shift and affecting the cutting accuracy. The steel plate is pretreated by the cleaning mechanism, effectively improving the cutting quality and efficiency. Before cutting, the oil stains and impurities on the surface of the steel plate are scraped off by the triangular rods. At the same time, the water supply device sprays water through the water spraying holes, further flushing away the oil stain impurities, making the surface of the steel plate cleaner. After the oil stains on the surface of the steel plate are cleaned, the problem of unstable positioning of the steel plate caused by the existence of oil stains is reduced when the preheating plate and the rotating roller extrude and position the steel plate. This cleaning method reduces the interference of impurities on the cutting process, avoids cutting defects and rough cutting surfaces caused by impurities, thereby improving the cutting quality. In addition, the surface of the cleaned steel plate is clean, and the cutting equipment can perform cutting positioning more accurately, reducing dimensional deviation and ensuring cutting accuracy. At the same time, the cleaning process is combined with the feeding process, and the first motor drives the rotating roller to rotate, realizing the automatic feeding of the steel plate and improving the cutting efficiency. After the steel plate is cleaned, the preheating plate heats it, so that the remaining water on the steel plate is dried, and at the same time, the steel plate is preheated to prevent the steel plate from deforming due to thermal stress caused by temperature difference during cutting, further ensuring the cutting quality. This combination of cleaning and preheating not only improves the cutting quality, but also reduces the subsequent grinding and trimming work caused by cutting defects, improving the overall production efficiency; (2) This device effectively optimizes the blanking and waste treatment processes. The cut steel plates and debris all fall on the rotating blanking plate. By driving the driving component to act through the telescopic electric cylinder, the rotating blanking plate is tilted, and the steel plates can smoothly slide towards the lower end, achieving automatic blanking, reducing manual intervention, and improving work efficiency. At the same time, the setting of the blanking rotating rod assists the steel plates to slide downward, preventing the steel plates from getting stuck on the rotating blanking plate, further ensuring the smoothness of blanking. During the blanking process, the debris generated by cutting will slide along the inclined surface of the rotating blanking plate and fall into the material leakage holes and enter the aggregate tank, realizing the automatic collection of debris. This design avoids the accumulation of debris on the workbench, reduces interference and damage to the cutting equipment, and is also convenient for subsequent cleaning work. When it is necessary to clean the debris in the aggregate tank, by removing the plugging rod, and using the driving component to drive the rotating blanking plate to tilt again, the debris in the aggregate tank can be poured out. The cleaning process is simple and convenient. This optimized blanking and waste treatment method not only improves production efficiency, but also keeps the working environment clean, reduces safety hazards and equipment failures caused by debris accumulation, and extends the service life of the equipment.

[0026] Working principle of the present invention: When cutting a steel plate, the steel plate is placed below the inverted U-shaped frame 311. The output shaft of the second motor 334 drives the first runner 335 to rotate. The first runner 335 drives the left-handed and right-handed double-threaded rod 336 to rotate through the second transmission belt 338 and the second runner 337. The left-handed and right-handed double-threaded rod 336 drives the two sliding blocks 333 to move, so that the distance between the two sliding blocks 333 becomes larger. The sliding block 333 drives the connecting short plate 331 to descend through the connecting rotating plate 332. The connecting short plate 331 drives the connecting base 317 to descend. The connecting base 317 drives the inverted U-shaped frame 311 to descend, so that the inverted U-shaped frame 311 drives the rotating rod 321 and the preheating plate 322 to contact the steel plate, and presses and fixes the steel plate. When cutting the steel plate, when the circular saw cutting machine contacts the steel plate, a lateral force is generated, which causes the steel plate to shift horizontally during the cutting process, affecting the cutting accuracy. The output end of the first motor 326 drives the driving gear 327 to drive the driven gear 325 to rotate. The driven gear 325 drives one of the rotating wheels 323 to rotate. The rotating wheel 323 drives the first transmission belt 324 to drive the other rotating wheels 323 to rotate. The rotating wheel 323 drives the rotating rod 321 to rotate through the connecting rod. When the rotating rod 321 rotates to drive the steel plate to move, the triangular rod 313 cleans the surface of the steel plate. The triangular rod 313 scrapes off the oil stains and impurities on the steel plate. The water supply device sprays water from the water spraying holes 314 through the connecting pipe 316 and the water passing pipe in the connecting cross bar 312. The water is sprayed onto the steel plate from the guiding holes 315, and by the way, washes away the oil stains and impurities scraped off by the triangular rod 313. After the water is sprayed out, the oil stains and impurities on the steel plate are washed away, which is convenient for the subsequent triangular rod 313 to scrape off the oil stains and impurities. When the steel plate passes below the inverted U-shaped frame 311 with water, the preheating plate 322 heats the steel plate, so that the remaining water on the steel plate is dried, and the steel plate is heated to prevent the steel plate from deforming due to thermal stress during cutting, and to prevent the oil stains and impurities from interfering with the contact between the saw blade and the steel plate during the cutting process, resulting in obvious marks and unevenness on the cutting surface. After cleaning the oil stains on the steel plate, the rotating rod 321 and the preheating plate 322 will not contact the oil stains, preventing sliding when positioning the steel plate, resulting in affecting the cutting accuracy; After the cutting device 2 cuts the steel plate, the chips generated by the cutting and the cut steel plate are both on the rotating blanking plate 421. At this time, the output end of the telescopic electric cylinder 436 retracts, the telescopic electric cylinder 436 drives the mounting plate 434 to move, the mounting plate 434 drives the sliding cross bar 433 to move, the sliding cross bar 433 pulls the connecting short rod 431 to descend through the rotating plate 432, the connecting short rod 431 drives one end of the rotating blanking plate 421 to descend, the other end of the rotating blanking plate 421 rotates in the mounting groove 12, the rotating blanking plate 421 inclines, and the steel plate slides towards the lower end of the rotating blanking plate 421. When the steel plate slides on the rotating blanking plate 421, the blanking rotating rod 425 assists the steel plate to slide downwards to prevent the steel plate from getting stuck on the rotating blanking plate 421. When the chips generated by the cutting slide along the inclined surface of the rotating blanking plate 421, they fall into the material leakage hole 422 and enter the aggregate tank 423. After the cutting is completed, the chips are cleaned and the steel plate is blanked to prevent the chips from accumulating and affecting the cutting. When it is necessary to clean the chips in the aggregate tank 423, the bolt is removed, the material blocking plug rod 442 is removed from one side of the rotating blanking plate 421, and the rotating blanking plate 421 is driven by the driving assembly 43 to incline so that the chips in the aggregate tank 423 are poured out.
