Description

Technical Field

[0001] The invention relates to the field of casting transfer, in particular to a material unloading and transfer device for mechanical casting processing. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with certain shapes, sizes and properties. After the casting of mechanical castings, further fine processing is required on their outer surfaces. Conventional unloading and transportation methods generally use manual unloading and then transfer by transfer vehicles or conveyors. When processing is carried out in the same factory, it is more efficient to use conveyors for transportation. However, most conventional conveyors can only carry out linear transportation. When different outer surfaces of different castings are processed differently, multiple conveyors need to be added for transportation. It is difficult to achieve different directional transportation effects for different castings by adjusting the conveying angle of the conveyor.

[0003] A Chinese patent discloses a pig iron casting processing site transfer device and its use method (application number: 2022111422853). The patent installs a first transfer fixed seat, a second transfer fixed seat and a third transfer fixed seat according to the mechanical position of the processing site, selects a linear guide rail and a circular guide rail according to the direction of transfer to adapt to different transportation paths, and can install a casting transport vehicle for material transportation. The casting transport vehicle can be transported and moved according to the installation path of the linear guide rail and the circular guide rail, which is convenient for transfer work. The structure is stable and convenient for improving the transportation effect and processing efficiency. During work, the position of the movable guide plate is adjusted, and the cast iron parts are placed above the transport plate. The guide roller is driven by an electric motor to rotate, and the cast iron parts on the upper end surface are driven to move. It can adapt to loading in different directions, facilitate position adjustment, and further improve the transfer effect.

[0004] However, the guide rail of the above patent is fixed and difficult to adjust the angle. The casting can only be processed by installing a workbench around the guide rail. It is difficult to achieve adaptive adjustment of the guide rail to connect with each workbench, and it is difficult for the device to turn the casting being transported to clean the sand and impurities above.
