Description

Technical Field

[0001] The utility model relates to the field of machining of mechanical parts. More specifically, the utility model relates to an automatic sawing equipment for alloy die-casting workpieces. Background Art

[0002] In the automated production process of bathroom equipment parts, die-casting is widely adopted as a conventional process. For die-cast workpieces, it is necessary to saw off the redundant metal structure parts of the mold runner part generated together with the die-casting process on the workpieces. During the production process, the products cast at high temperature often have a high temperature, resulting in the products in the mold needing to wait for a certain cooling time before being cut by workers. This is not conducive to the overall efficiency of the production line, and since the sawing process often requires workers to hold the workpieces by hand, there are also certain safety hazards.

[0003] The patent with the authorization publication number CN219443683U discloses a single-axis rotating double-station automatic sawing machine for cutting risers of castings and die-castings. Through the mutually cooperating frame, gantry, Z-axis guide rail assembly, Z-axis moving part, spindle part, and saw blade, the saw blade can descend and complete sawing. However, in the above technical solution, only by controlling the movement of the saw blade in the Z-axis can the sawing effect be achieved, which is only suitable for the sawing and machining scenarios of some workpieces with simple structures. For complex die-cast workpieces, there may be multiple positions or various angles for the runner positions to be sawn. Therefore, it is necessary to provide an automatic sawing equipment for alloy die-casting workpieces to meet the automated sawing of complex die-cast workpieces in the high-temperature state after demolding.
