Description

Technical Field

[0001] The utility model relates to the technical field of bearing box production, in particular to a multi-channel bearing box casting device. Background Art

[0002] The bearing box is an important component in mechanical equipment, mainly used to support and fix the bearing to ensure the normal operation of the mechanical equipment. The bearing box casting device is a device specially used to manufacture bearing boxes. It uses casting technology to pour molten metal liquid (such as molten iron, molten copper, etc.) into a pre-prepared mold. After the metal liquid cools and solidifies, the finished product in the mold is taken out to obtain the required bearing box.

[0003] During the production of bearing housings, despite the use of advanced mold design and manufacturing technology, burrs often remain in the inner cavity after demolding. These burrs not only affect the appearance quality of the bearing housing, but more importantly, they will have adverse effects on the installation and use of the bearings, such as increased wear and shortened service life. To solve this problem, workers are traditionally required to fix the bearing housing after casting and cooling, and use manual tools such as sandpaper and files to deburr it. However, this process has many disadvantages: first, the bearing housing needs to be moved multiple times between different processes, which not only increases the labor intensity of the workers, but may also cause the bearing housing to be damaged during transportation; second, the manual deburring method is inefficient and it is difficult to ensure the quality of deburring; finally, workers need to directly contact the metal surface and tools during the deburring process, which poses a high risk of scratches and bumps.

[0004] To address the above issues, a multi-channel bearing box casting device has emerged. This device not only realizes the automated casting and demoulding of the bearing box, but also integrates a deburring function, which can automatically deburr the bearing box after casting.
