Description

Technical Field

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

[0002] After a billet is cut by a flame cutting machine, burrs are formed on its lower surface. Most existing billet deburring machines use a single double-edged scraper to remove the burrs. Specifically, during the billet's transportation, the scraper rises and uses one blade to remove burrs from the billet's head, and the other blade to remove burrs from the billet's tail. However, this process primarily relies on a conveyor roller to drive the billet relative to the scraper, and the scraper itself only has a lifting function. For example, patent publication number CN212350642U discloses a reciprocating spring cutting and deburring machine for continuous casting billets. During operation, the billet is placed on a conveyor roller bed. A computer controls the clockwise rotation of the conveyor rollers, feeding the billet until the front end exceeds the deburring machine's scraper position, where it stops. The lifting mechanism then rises and drives the scraper against the billet's lower surface. The computer then controls the counterclockwise rotation of the conveyor rollers, and the scraper, in conjunction with the billet's own weight, removes the burrs from the billet's front end. However, in actual production, it is found that since the transmission roller is usually long, the speed and movement distance control accuracy of this method of controlling the movement of the billet relative to the scraper is relatively low, and burrs are easily not removed cleanly.

[0003] In the prior art, deburring can also be accomplished using devices such as cleaning rollers. For example, Patent No. CN210498634U discloses a billet deburring machine equipped with a liftable deburring roller assembly. After the deburring roller assembly rises and contacts the billet, it is driven by a variable frequency motor to rotate and deburr. To ensure compaction of the billet, Patent No. CN214108721U also discloses a device that incorporates front and rear pressure roller assemblies and cleaning rollers. However, the deburring rollers of these devices, aside from rotating and lifting, cannot be moved or adjusted along the billet transport direction. Utility Model Content

[0032] like Figures 1 to 4 As shown, the input side and the output side of the frame can be provided with swingable pressure rollers according to actual needs to cooperate with pressing the head end or the tail end of the billet 6, thereby ensuring that the billet 6 can fully contact with the scraper unit 1. The pressure rollers are well-known in the art, for example, the pressure roller structure in the CN214108721U patent can be adopted, or other suitable swinging pressure roller structures can be adopted.

[0033] The working principle of this utility model is:

[0034] like Figure 1 As shown, when the utility model is working, when the utility model is located at the input side of the frame, the scraper unit 1 rises and cooperates with the pressure roller on the corresponding side to clamp the head end of the billet 6, and then the scraper unit 1 is driven by the mobile frame 2 to move in the same direction as the transmission direction of the billet 6 to complete the deburring operation of the head end of the billet 6, and at this time the moving speed of the mobile frame 2 needs to be greater than the transmission speed of the transmission roller, and when the scraper unit 1 is separated from the head end of the billet 6, as shown in FIG. Figure 2 As shown, at this time, the utility model moves to the output side of the frame, and then the billet 6 continues to be driven by the transmission roller until it is as shown in FIG. Figure 3 After the tail end of the billet 6 moves to the top of the utility model, the scraper unit 1 rises again and cooperates with the pressure roller on the corresponding side to clamp the tail end of the billet 6. Then the scraper unit 1 is driven by the moving frame 2 to move in the opposite direction of the billet 6 transmission direction to complete the deburring operation of the tail end of the billet 6. After the scraper unit 1 is separated from the billet 6, as shown in FIG. Figure 4As shown, at this moment, the utility model returns to the input side of the frame again and waits for the next billet 6 to be input.

[0035] The utility model can adopt a conventional integrated scraper, or it can be Figure 6 The scraper unit 1 shown in the figure adopts a segmented structure designed for the lower surface characteristics of the billet 6, wherein Figure 6 As shown, due to the reasons of continuous casting and roller transportation, the lower surface of the billet 6 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 6. The scraper unit 1 with a segmented structure changes the single scraper into a segmented structure including multiple single scrapers 101. The width of each scraper is relatively small. In this way, when the utility model is working, each single scraper 101 can automatically compress the spring 105 according to the protrusions and depressions on the lower surface of the billet 6 to achieve height adjustment to ensure that the burrs are removed cleanly. In this embodiment, 5 single scrapers 101 are included. The width of the three middle single scrapers 101 combined is close to the cross-sectional width of the billet 6. Since the cross-section of the billet 6 is small, it is easy to deform in a red-hot state and may also deviate from the center during transportation. When the billet 6 deviates to the left, Figure 6 The leftmost scraper 101 is used when the billet 6 deflects to the right. Figure 6 The rightmost single scraper 101 will be utilized, so that the utility model can have the single scraper 101 work within the deformation range of the billet 6, thereby avoiding the situation where the burrs are not scraped due to the narrow width of the tool.
