Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft processing, and more specifically, to a quenching device for crankshaft processing. Background Art

[0002] The crankshaft is the main rotating part of the engine. After the connecting rod is installed, it can take over the up and down movement of the connecting rod and convert it into a circular motion. It is an important part of the engine. During the crankshaft production process, the crankshaft needs to be quenched, and a quenching device will be used.

When crankshafts of different sizes need to be processed, new quenching mechanisms need to be replaced, which is not only time-consuming and labor-intensive, but also increases the cost of use. At the same time, some quenching devices will generate a large amount of iron filings during quenching. The next time the workpiece is quenched, the iron filings will adhere to the outer surface of the workpiece, affecting the subsequent operation of the workpiece. Therefore, in view of the above problems, a quenching device for crankshaft processing is specially proposed. Utility Model Content
