Description

Technical Field

[0001] The utility model relates to the technical field of metal casting processing, in particular to surface treatment equipment used for ferrous metal casting. Background Art

[0002] Ferrous metal materials are the general term for iron, chromium and manganese in industry, and also include alloys of these three metals, especially alloy steel and steel. Ferrous metals mainly refer to iron, manganese, chromium and their alloys, non-ferrous metals, ferrous metals mainly refer to iron, manganese, chromium and their alloys, such as steel, pig iron, iron alloys, cast iron, etc. Metal castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling and subsequent treatment such as surface grinding, the resulting object has a certain shape, size and performance. Among them, regular rectangular metal castings are one of the commonly used metal castings. After processing and preparing rectangular metal castings, they need to be surface ground.

[0003] The prior art cannot complete the flipping of metal parts. Only one side can be polished and then manually flipped. However, the temperature of the metal parts is very high after being polished, and care must be taken to prevent burns when flipping.

[0004] For example, Chinese patent CN220548055U discloses a surface treatment device for ferrous metal casting, which is provided with a fixing mechanism, and two retractable clamps are provided on both sides of the fixing mechanism for adapting to and fixing metal castings of different sizes. The fixing mechanism is symmetrically slidably arranged on an operating table, and the two clamps are used for lateral fixing. The two fixing mechanisms are squeezed against each other for longitudinal fixing, thereby increasing the stability of the metal casting during grinding. A flipping mechanism is provided, and when one side of the rectangular metal casting is polished, the flipping mechanism can be used to flip it over and polish the other side, thereby avoiding the danger of manual flipping and effectively increasing the practicality of the equipment.

[0005] However, during the grinding process of metal castings, the device needs to remove the ground workpiece and then clamp and fix the next workpiece to be ground, which wastes too much time in the process of taking and placing, thereby affecting the production efficiency of metal castings.

[0006] For this reason, we urgently need to provide a surface treatment equipment for ferrous metal casting. Utility Model Content
