Description

Technical Field

[0001] The utility model belongs to the technical field of steel water sample preparation tools, and particularly relates to a tool for quickly removing burrs from steel water samples. Background Technique

[0002] During the process of refining furnace for composition adjustment, a steel water sampler is used to take out the steel water sample and send it to the laboratory for analyzing the composition of the steel water. When sampling, the steel water enters the chamber formed by two steel sheets. After taking out, the steel sheets are broken open to take out the steel sample.

[0003] Due to the structural reasons of the sampler, after the steel sample is broken open, burrs will appear on the side of the steel sample. When sending the sample, tools are needed to remove the burrs before sending it to the laboratory. Mainly use pliers or hammers to remove burrs one by one, which takes a long time. When removing burrs, one hand needs to hold the steel sample and the other hand needs to hold the tool to remove the burrs. Since the steel sample is relatively small, there is a risk of hand injury to the operator during the process of removing burrs. Using tools to remove burrs takes time and it needs to be operated 4 - 5 times to remove the burrs on the steel sample, which affects the sample sending time and is not conducive to the stable production rhythm. Summary of the Invention

[0004] The purpose of the utility model is to provide a tool for quickly removing burrs from steel water samples to solve the problems existing in the prior art.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a tool for quickly removing burrs from steel water samples, including a steel plate. A through - hole is opened on the steel plate. Two legs are welded on both sides of the bottom surface of the steel plate. A rubber pad is jointly pasted at the bottom ends of the two legs. A rubber plate is pasted at one end of the upper surface of the steel plate. Sandpaper is pasted on the rubber plate. A bracket is welded at the central position of the upper surface of the steel plate. A sleeve is welded on the bracket. An impact rod is inserted into the sleeve.

[0006] Further, one end of the through - hole is circular and the other end is square. The shape of the through - hole matches the outer contour of the steel water sample. The square end of the through - hole communicates with the outside of the steel plate, and there is a chamfer at the upper edge of the through - hole.

[0007] Further, the bracket is L - shaped. One end of the bracket is bent in an L - shape and extends directly above the circular end of the through - hole.

[0008] Further, the sleeve is tubular. The sleeve is welded at one end of the bracket above the through - hole, and the axis of the sleeve coincides with the axis of the circular end of the through - hole.

[0009] Further, the thickness of the steel plate is 30mm.

[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model can quickly remove the burrs of the steel water sample and can also polish the burrs, shortening the time for treating the burrs of the steel water sample and reducing the risk of personnel injury when removing the burrs of the steel sample.

[0012] 2. By placing the steel water sample on the through hole and hammering the impact rod, the burrs of the steel water sample can be quickly removed by using the steel plate, thereby shortening the time for treating the burrs of the steel water sample.

[0013] 3. The rubber pad can catch the falling steel water sample to prevent damage to the desktop or the ground.

[0014] 4. The sandpaper is pasted on the rubber plate. The flexibility of the rubber plate can adapt to the uneven surface of the steel water sample and better polish the surface layer. Compared with directly pasting on the steel plate, it is less likely to be cut by the steel water sample.

[0015] 5. The chamfer at the upper edge of the through hole can keep the steel water sample stable and reduce the risk of the steel water sample bursting out during hammering.

[0016] 6. The axis of the sleeve coincides with the axis of the circular end of the through hole, so that the force application point of the steel water sample can be ensured to be at the exact center of the circular end, preventing it from bursting out during hammering.

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] As Figure 1-2 shown, a tool for quickly removing the burrs of the steel water sample includes a steel plate 1. A through hole 2 is provided on the steel plate 1. Two legs 3 are welded to both sides of the bottom surface of the steel plate 1. A rubber pad 4 is jointly pasted at the bottom ends of the two legs 3. One end of the upper top surface of the steel plate 1 is pasted with a rubber plate 5. Sandpaper 6 is pasted on the rubber plate 5. A bracket 7 is welded at the central position of the upper top surface of the steel plate 1. A sleeve 8 is welded on the bracket 7. An impact rod 9 is inserted into the sleeve 8.

[0022] One end of the through-hole 2 is circular, and the other end is square. The shape of the through-hole 2 matches the outer contour of the molten steel sample 10. The square end of the through-hole 2 communicates with the outside of the steel plate 1, and there is a chamfer on the upper edge of the through-hole 2.

[0023] The circular end of the through-hole 2 is used to pass through the circular end of the molten steel sample 10, and the square end of the through-hole 2 is used to pass through the cylindrical end of the molten steel sample 10. The chamfer on the upper edge of the through-hole 2 can keep the molten steel sample 10 stable and reduce the risk of the molten steel sample 10 popping out during hammering.

[0024] The through-hole 2 is used to allow the molten steel sample 10 to pass through the steel plate 1 and use the steel plate 1 to scrape off burrs. Therefore, the shape of the through-hole 2 matches the outer contour of the molten steel sample 10, that is, the shape of the through-hole 2 is 0.3 - 0.5 mm larger than the outer contour of the molten steel sample 10. If it is too large, the burrs cannot be removed completely, and if it is too small, the molten steel sample 10 is likely to be stuck.

[0025] The bracket 7 is L-shaped, and one end of the bracket 7 extends directly above the circular end of the through-hole 2 after being bent in an L-shape.

[0026] The sleeve 8 is tubular, and the sleeve 8 is welded to one end of the bracket 7 above the through-hole 2. The axis of the sleeve 8 coincides with the axis of the circular end of the through-hole 2, so that the force point of the molten steel sample 10 can be located exactly in the center of the circular end, preventing it from popping out during hammering.

[0027] The thickness of the steel plate 1 is 30 mm. A too thin steel plate 1 is likely to deform during multiple hammerings, and the 30-mm steel plate 1 has good stability.

[0028] The working principle of the present utility model is as follows:

[0029] During use, lift the impact rod 9 by hand, place the molten steel sample 10 on the through-hole 2 and lock it in place, then release the impact rod 9. One end of the impact rod 9 abuts against the surface of the molten steel sample 10. Or, in order to protect the molten steel sample 10, place a circular rubber between the impact rod 9 and the molten steel sample 10, and use a hammer to strike the impact rod 9. The molten steel sample 10 instantly passes through the through-hole 2 and falls onto the rubber pad 4, preventing the molten steel sample 10 from falling quickly and damaging the tabletop or the ground. At the same time, the burrs on the molten steel sample 10 are scraped off by the steel plate 1, thus completing the operation of removing burrs from the molten steel sample 10. Pick up the molten steel sample 10 and polish its surface on the sandpaper 6 to remove the oxide layer. Since the sandpaper 6 is adhered to the rubber plate 5, the flexibility of the rubber plate 5 can adapt to the uneven surface of the molten steel sample 10, better polishing the surface layer. Compared with directly adhering to the steel plate 1, it is less likely to be cut by the molten steel sample 10. Since the upper edge of the through-hole 2 is chamfered, the risk of the molten steel sample 10 popping out during hammering is reduced.

Without departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention.
