Description

Technical Field

[0001] The utility model relates to the technical field of pouring cup preparation, and more specifically to a pouring cup processing bottom edge grinding device. Background Art

[0002] The outer bottom edge of the pouring cup is the part that contacts the mold or casting platform. The flatness and smoothness of this edge are crucial to ensure the stability and sealing of the pouring cup during the casting process. If there are burrs, protrusions or other unevenness on the bottom edge, it may cause the molten metal to leak during the pouring process and affect the quality of the casting. The main purpose of bottom edge grinding is to remove these uneven parts and make the bottom edge of the pouring cup smoother and more uniform to ensure the smooth casting process. This step is usually carried out after the pouring cup is manufactured and is an important part of the preparation work before casting.

[0003] The Chinese authorized utility model patent with announcement number CN213795690U discloses a device for quickly polishing a pouring cup. In the above patent, the pouring cup to be polished is placed horizontally in a positioning seat, and the mouth of the pouring cup is polished flat by a high-speed rotating cutting blade. During polishing, the setting of a circular retaining ring can keep the pouring cup in a vertical state at all times, thereby ensuring the polishing quality of the pouring cup. The above patent also has some defects. The positioning seat set therein can only polish pouring cups of one caliber specification, and most companies will produce pouring cups of different caliber specifications. When using the above patent, multiple sets of devices need to be configured to cope with the preparation of pouring cups of different calibers. Utility Model Content
