Description

Technical Field

[0001] The utility model mainly relates to the technical field of die steel processing equipment, in particular to a die steel surface polishing device with dual functions of polishing liquid and polishing pad. Background Art

[0002] Mold steel is a type of steel used to manufacture cold stamping dies, hot forging dies, die-casting dies and other molds. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing technology, the precision output of the product and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to reasonable structural design and processing accuracy.

[0003] A polishing machine is an electric tool. It consists of basic components such as a base, a polishing disc, a polishing fabric, a polishing cover and a lid. The key to operating a polishing machine is to try to obtain the maximum polishing rate so as to remove the damaged layer generated during polishing as quickly as possible. At the same time, the polishing damaged layer must not affect the final observed structure, that is, it will not cause false structure. The former requires the use of coarser abrasives to ensure a higher polishing rate to remove the polished damaged layer, but the polishing damaged layer is also deeper. The latter requires the use of the finest material to make the polishing damaged layer shallower, but the polishing rate is low. The polishing disc is also called a polishing pad, polishing leather, polishing cloth and polishing sheet. It has many functions. For example, after the stone is cut, a polishing pad will be used to polish the surface to make it brighter and smoother. In the polishing process, a polishing liquid is also needed. The polishing liquid is a water-soluble polishing agent that does not contain any sulfur, phosphorus or chlorine additives. The polishing liquid has good degreasing, rust prevention, cleaning and gloss enhancement properties, and can make metal products exceed the original gloss.

[0004] Nowadays, in the process of polishing mold steel, the polishing pad rotates quickly to grind and polish the surface of the mold steel. At the same time, the staff also needs to add polishing liquid to the rotating polishing pad. Grinding and polishing and adding polishing liquid must be taken into account at the same time, which is very inconvenient and increases the intensity of work. After the polishing liquid is sprinkled on the polishing pad, due to the action of centrifugal force, part of the polishing liquid will splash out, causing waste and inconvenient for subsequent cleaning.

At the same time, the pressure pump 26 is started to extract the polishing liquid in the liquid storage tank 25. Then, the polishing liquid enters the sealing sleeve 224 through the bent pipe 27 and the guide pipe 28, and then enters the perforated connecting shaft 221. Then, it flows out from the liquid outlet part 231 through the inner cavity of the transmission shaft 222. Under the action of centrifugal force, the polishing liquid can quickly cover the upper side of the polishing pad body 24.

Through the liquid inlet component 22, when the motor 21 is started, the sealing sleeve 224 will not rotate during the rotation of the connecting shaft 221 with a hole and the transmission shaft 222, thereby ensuring that the polishing liquid stably enters the connecting shaft 221 with a hole, and the inner edge positions of the upper and lower ends of the sealing sleeve 224 are both provided with sealing rings 225. Through the sealing ring 225, the sealing of the connection position is further strengthened.
