Description

Technical Field

[0001] The utility model relates to the technical field of square billet deburring, in particular to a segmented square billet deburring scraper. Background Art

[0002] After a billet is cut by a flame cutting machine, burrs will form on its lower surface. In the prior art, a scraper is usually raised to support the lower surface of the billet during transportation, and the billet is moved relative to the scraper to achieve deburring. However, the scraper used in the prior art billet deburring machine is usually a one-piece scraper. The scraper width is slightly wider than the width of the billet cross-section. During the casting process, the cross-section of the billet shrinks and deforms, and the lower surface of the billet is prone to bulges or depressions. Because the blade of the one-piece scraper is flat, when scraping burrs on a bulge, burrs on both sides may remain. When scraping burrs on a concave part, burrs in the middle may remain, resulting in incomplete burr removal.

[0003] The patent with publication number CN116274911A discloses a deburring scraper device suitable for bending and deformation of slabs. The scraper of the device is installed at the lower end of the knife seat component, and the knife seat component includes a swinging knife seat, a fixed knife seat and a pin shaft structure. However, the scraper of the device is still an integral scraper, and the bending deformation of the slab is not the same as the bulge or depression produced on the lower surface of the square billet.

[0004] Patent publication number CN212350644U discloses a rotary scraper-type billet deburring device. Multiple scraper groups are mounted on the outer wall of a blade roller, evenly spaced along the roller's circumference. Each scraper group includes multiple blades, each arranged in a spiral pattern on the outer wall of the roller. However, billets typically have a relatively narrow cross-section, making this type of scraper unsuitable for deburring. Furthermore, this multiple-blade arrangement fails to address the problem of incomplete deburring, which can be caused by bumps or depressions on the billet's lower surface. Utility Model Content

[0005] The purpose of the utility model is to provide a segmented billet deburring scraper, which changes the single scraper in the prior art into a segmented structure including multiple individual scrapers according to the characteristics of the lower surface of the billet. The width of each scraper is relatively small. In this way, when the utility model is working, each individual scraper can automatically compress its own spring according to the protrusions and depressions on the lower surface of the billet to achieve height adjustment to ensure that burrs are completely removed.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A segmented billet deburring scraper comprises a scraper mounting seat, a single scraper, a knife rod and a spring, wherein the scraper mounting seat is provided with a plurality of mounting holes, and a spring is provided in each mounting hole, the knife rod is inserted into the corresponding mounting hole and is floatingly supported by the corresponding spring, the upper end of the knife rod is fixedly connected to the corresponding single scraper, and the single scrapers are arranged in a line and the total width is greater than the cross-sectional width of the billet.

[0008] A guide sleeve assembly is provided between the outer wall of the knife rod and the inner wall of the mounting hole, a spring is provided in the lower part of the guide sleeve assembly, and a spring upper limit surface is provided in the middle part of the knife rod to abut against the upper end of the spring, and a spring lower limit surface is provided at the lower end of the guide sleeve assembly to abut against the lower end of the spring.

[0009] The guide sleeve assembly includes an upper guide sleeve and a lower guide sleeve, wherein the lower guide sleeve is fixed at the lower part of the corresponding mounting hole, the spring is arranged in the lower guide sleeve, the lower end of the lower guide sleeve is provided with the spring lower limit surface, and the upper guide sleeve is arranged at the upper part of the corresponding mounting hole and sleeved on the upper part of the tool rod.

[0010] A knife bar locking shaft is provided at the lower end of the knife bar, and the knife bar locking shaft extends to the outside of the scraper mounting seat and is threadedly connected to the corresponding lock nut.

[0011] A washer assembly is sleeved on the knife bar locking shaft, and the washer assembly is arranged between the lock nut and the lower surface of the scraper mounting seat.

[0012] The total width of the remaining single scrapers except the outermost single scrapers at both ends is greater than the cross-sectional width of the billet.

[0013] The advantages and positive effects of this utility model are:

[0014] 1. According to the characteristics of the lower surface of the billet, the utility model changes the single scraper in the prior art into a segmented structure including multiple individual scrapers. The width of each scraper is relatively small. In this way, when the utility model is working, each individual scraper can automatically compress its own spring according to the protrusions and depressions on the lower surface of the billet to achieve height adjustment to ensure that burrs are completely removed.

[0015] 2. The present invention takes into account that the cross-section of the billet is small, and it is easy to deform in a red-hot state, and it may also deviate from the center during transportation. Therefore, the combined width of each single scraper in the scraper assembly of the present invention is greater than the width of the billet, wherein the combined width of all the single scrapers except the single scrapers at the outermost ends on both sides is close to the cross-sectional width of the billet and greater than the width of the billet. When the billet deflects to the left or right, the single scrapers at the outermost ends on both sides will be utilized. In this way, the present invention can have the single scrapers work within the deformation range of the billet, thereby avoiding the situation where burrs are not scraped off due to the narrow width of the tool.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, the utility model includes a scraper mounting seat 9, a single scraper 1, a knife rod 2 and a spring 5, wherein the scraper mounting seat 9 is provided with a plurality of mounting holes, and a spring 5 is provided in each mounting hole, the knife rod 2 is inserted into the corresponding mounting hole and is floatingly supported by the corresponding spring 5, the upper end of the knife rod 2 is fixedly connected to the corresponding single scraper 1 by a bolt, and the single scrapers 1 are arranged in a line and the total width is greater than the cross-sectional width of the square billet 10.

[0020] like Figure 1 As shown, in this embodiment, a guide sleeve assembly is provided between the outer wall of the knife rod 2 and the inner wall of the mounting hole to ensure that the knife rod 2 can smoothly slide vertically up and down along the mounting hole, a spring 5 is provided in the lower part of the guide sleeve assembly, and a spring upper limit surface 202 is provided in the middle part of the knife rod 2 to abut against the upper end of the spring 5, and a spring lower limit surface 8 is provided at the lower end of the guide sleeve assembly to abut against the lower end of the spring 5.

[0021] like Figure 1 As shown, in this embodiment, the guide sleeve assembly includes an upper guide sleeve 3 and a lower guide sleeve 4, wherein the lower guide sleeve 4 is fixed to the lower part of the corresponding mounting hole, the spring 5 is arranged in the lower guide sleeve 4, and the lower end of the lower guide sleeve 4 is provided with the spring lower limit surface 8, and the upper guide sleeve 3 is arranged at the upper part of the corresponding mounting hole and is sleeved on the upper part of the tool rod 2.

[0022] like Figure 1 As shown, in this embodiment, a shank locking shaft 201 is provided at the lower end of the shank 2. The shank locking shaft 201 extends outside the scraper mounting seat 9 and is threadedly connected to the corresponding lock nut 6.

[0023] The total width of the remaining single scrapers 1 except the outermost single scrapers 1 at both ends is greater than the cross-sectional width of the billet 10 .

[0024] The working principle of this utility model is:

[0025] like Figure 1 As shown, due to the reasons of continuous casting and roller transportation, the lower surface of the billet 10 is not flat. If the scraper is made into a single integral form, it is difficult to adapt to the uneven shape of the lower surface of the billet 10. The utility model changes the single scraper into a segmented structure including multiple single scrapers 1. The width of each scraper is relatively small. In this way, when the utility model is working, each single scraper 1 can automatically compress the spring 5 according to the protrusions and depressions on the lower surface of the billet 10 to achieve height adjustment to ensure that the burrs are removed cleanly. In this embodiment, five single scrapers 1 are included, and the width of the three middle single scrapers 1 combined is similar to and larger than the cross-sectional width of the billet 10. Since the cross-sectional area of ​​the billet 10 is small, it is easy to deform in a red-hot state and may also deviate from the center during transportation. When the billet 10 deviates to the left, Figure 1 The leftmost scraper 1 is used when the billet 10 deflects to the right. Figure 1 The rightmost single scraper 1 will be utilized, so that the utility model can have the single scraper 1 work within the deformation range of the billet 10, thereby avoiding the situation where the burrs are not scraped due to the narrow width of the tool.
