Description

Technical Field

[0001] This application relates to the technical field of polishing detection devices, and in particular to a molten iron sample polishing detection device. Background Art

[0002] Molten iron is the common name for liquid iron. Its composition is elemental iron, which is a pure substance and is liquid iron. The melting point of iron is 1535 degrees, and it is a substance that absorbs heat quickly and dissipates heat slowly. To test the wear resistance of different molten irons, after the factory produces molten irons with different ratios, it is necessary to wait for them to cool and solidify, and then place them in a dedicated sample polishing device for detection.

[0003] Common molten iron polishing detection devices are usually table-type. A pair of circular grooves are provided on the tabletop. The bottom surface of the groove is equipped with a motor, and the power end of the motor is located inside the circular groove, while the polishing wheel is located inside the circular groove.

[0004] During polishing, the solidified molten iron sample is placed on the grinding wheel for grinding. Although it is relatively convenient, since the polishing and grinding work is carried out inside the circular groove, the generated debris will accumulate in the groove. Although the existing device is provided with debris leakage holes, due to the high-speed rotation of the grinding wheel, the debris splashes at a relatively fast speed. Inevitably, some debris splashes under the grinding wheel, and excessive accumulation will cause the bottom of the grinding wheel to be subjected to friction, thereby increasing the wear degree of the grinding wheel and reducing its service life. During cleaning, the staff still needs to disassemble the grinding wheel, which is rather troublesome and affects the normal progress of the polishing detection work. Utility Model Content

[0024] The following further elaborates on this application in conjunction with the attached Figures 1-6 to further explain this application in detail.

[0025] The embodiment of this application discloses a molten iron sample polishing detection device. Referring to Figures 1-6 , a molten iron sample polishing detection device includes a polishing workbench body 1, a chip collection drawer 2, and a polishing grinding wheel 3.

The cleaning mechanism is installed on the motor transmission shaft 13 and is used for cleaning the polishing groove; the material guiding mechanism is installed inside the polishing workbench body 1 and is used for the precise dropping of broken materials into the chip collection drawer 2.

[0026] When in use, the drive motor 11 is started by controlling the switch, at which time the polishing wheel 3 rotates at high speed, and the solidified molten iron sample is fitted with the polishing wheel 3, and polishing detection can be performed. The polishing detection operation steps of the equipment are consistent with the use of the existing device. During the polishing process, part of the metal debris generated will be thrown into the long chip leakage hole 4, thereby colliding with the inner wall of the chip guide tube 5, and finally falling into the chip collection drawer 2, while part of it will collide with the inner wall of the polishing groove, and the debris that flies to the bottom of the polishing groove will be scraped by the cleaning brush rod 12, and then thrown into the long chip leakage hole 4, which can be easily cleaned.

[0027] In this embodiment, if Figure 3 and Figure 4 As shown, the cleaning mechanism includes a mounting collar 14 sleeved on the motor drive shaft 13, and a pair of cleaning brush rods 12 fixed on the mounting collar 14, the mounting collar 14 is fixed by a nut, and the bristles on the cleaning brush rods 12 are connected to the bottom of the polishing groove, a pair of U-shaped blocks 16 are fixed on the motor drive shaft 13, and a pair of U-shaped openings 15 are opened on the mounting collar 14, and the U-shaped openings 15 and the U-shaped blocks 16 are adapted to each other; when replacing, remove the nut fixed on the top of the polishing wheel 3, and then remove the polishing wheel 3, and then pull out the mounting collar 14, so as to facilitate the replacement of the cleaning brush rod 12 that is severely worn, thereby improving practicality.

[0028] In this embodiment, if Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the material guiding mechanism includes a pair of chip guiding barrels 5 installed in the inner cavity of the polishing workbench body 1, and the two chip guiding barrels 5 are respectively located directly above the chip collecting drawer 2. A pair of mounting slide bars 9 are fixed at the top of the chip guiding barrel 5, and a mounting slide rail 10 is fixed in the inner cavity of the polishing workbench body 1.

The polishing workbench body 1 is provided with a screw hole matched with the hand-tightening bolt 8, and a handle 7 is fixed at the bottom of the connecting plate 6. The chip guiding barrel 5 is a truncated cone shape with a wide top and a narrow bottom. The top of the chip guiding barrel 5 covers the bottom surface of the polishing groove, and the top of the chip guiding barrel 5 is provided with an obstacle-proof opening 19. The length and width of the obstacle-proof opening 19 are both larger than the driving motor 11.

At this time, the polishing grinding wheel 3 rotates at a high speed. Fit the solidified molten iron sample with the polishing grinding wheel 3, and then polishing and detection can be carried out. The polishing and detection operation steps of this device are the same as those of the existing device. During the polishing process, some of the generated metal chips will be thrown into the chip leakage long hole 4, thus colliding with the inner wall of the chip guide cylinder 5 and finally falling into the chip collection drawer 2. And some of the chips that collide with the inner wall of the polishing groove and fly to the bottom of the polishing groove will be scraped by the cleaning brush rod 12, thus being thrown into the chip leakage long hole 4, which is convenient for cleaning. When replacing, remove the nut fixed on the top of the polishing grinding wheel 3, then remove the polishing grinding wheel 3, and then the installation collar 14 can be pulled out, which is convenient for replacing the severely worn cleaning brush rod 12, improving the practicability. By setting the installation collar 14 and the cleaning brush rod 12, the cleaning brush rod 12 can rotate following the driving motor 11 for polishing, so that the residual chips in the polishing groove can be cleaned down, eliminating the need for the traditional operation of disassembling the polishing grinding wheel 3, facilitating cleaning and use.
