3results about How to "Simplify the polishing process" patented technology

The application discloses a metal polishing device, and belongs to the technical field of metal polishing, which is used for polishing the side edges of a workpiece in two modes of feeding the workpiece in the direction of a polishing belt and sliding the workpiece transversely, and comprises a belt polishing assembly and a multifunctional operation table fixedly installed with the belt polishing assembly. The multifunctional operation table is used for assisting the workpiece to slide in the direction of the belt polishing assembly or transversely, specifically, an operator can push the workpiece in the direction of the polishing belt of the belt polishing assembly, and the frame is fed in the direction of the polishing belt of the belt polishing assembly together with the workpiece to complete polishing; another mode is that the frame is moved close to the polishing belt of the belt polishing assembly, the limiting blocks are located on both sides of the polishing belt of the belt polishing assembly, the workpiece is slid transversely under the guidance of the roller, and the polishing belt of the belt polishing assembly is limited by the limiting blocks, so that the polishing belt of the belt polishing assembly is not fallen off in the working process.

The utility model discloses a piston polishing device which comprises an installation table, two feeding mechanisms arranged on the installation table in a mirror image mode and a piston polishing mechanism arranged on the installation table and located between the two feeding mechanisms. The technical problems that a feeding mechanism on an existing polishing device special for the piston is poor in operation stability, and due to the fact that piston polishing procedures on the existing polishing device are various, abrasion of the device is large are solved. The feeding mechanism is simple in structure, scientific and reasonable in design and convenient to use, the first buffering telescopic pipe and the second buffering telescopic pipe are arranged and used for buffering the movement of the feeding mechanism, and the stability of the movement of the feeding mechanism is improved; the piston pin hole polishing device is provided with the two feeding mechanisms which are distributed in a mirror image mode, the two feeding mechanisms are matched with each other to polish a piston pin hole, and on the premise that the piston polishing quality is guaranteed, the piston polishing procedure is simplified, and device abrasion is reduced.

The invention provides an electrolyte, a polishing method and a corrosion method for an alloy, and relates to the technical field of metallographic analysis. The electrolyte is used for performing electrolytic polishing or electrolytic corrosion on the alloy; the electrolyte comprises perchloric acid, hydrochloric acid and absolute ethyl alcohol; wherein the perchloric acid accounts for 50-60 parts by volume, the hydrochloric acid accounts for 50-60 parts by volume, and the absolute ethyl alcohol accounts for 400-480 parts by volume. According to the method, the alloy is placed in the electrolyte to be subjected to electrolytic polishing; wherein the alloy is used as an anode, and a nickel sheet is used as a cathode; the scratch defect formed on the alloy surface can be avoided, so that the polishing effect is ensured; meanwhile, the polishing process is simple, and the polishing time is short and is about 10-15 s; meanwhile, the alloy is placed in electrolyte for electrolytic corrosion; wherein the alloy is used as an anode, and a nickel sheet is used as a cathode; the method can be used for corroding the GH3536 alloy fused and formed by a laser powder bed and corroding out a precipitated phase at the grain boundary of the GH3536 alloy.
