Description

Technical Field

[0001] This utility model relates to an adjustable mold base, belonging to the technical field of track link forging mold installation. Background Technology

[0002] Track links are crucial components in the tracks of construction machinery such as bulldozers and excavators, and there is a large market demand for them. Track links operate in harsh environments and are subjected to complex stresses, needing to withstand significant random alternating loads during operation. They are among the most vulnerable components to failure in the walking systems of tracked construction machinery. The manufacturing process of track links includes die forging and pressing, which must be carried out on a die forging and pressing machine.

[0003] A search revealed patent application CN202122081198.9, which discloses a composite die for precision cutting of track links. This composite die solves the aforementioned problems by simultaneously precision cutting the forged track links, removing burrs, punching, and shaping, automating the burr-cutting process and significantly improving forging efficiency. While this patent can process track links, its current technology is not comprehensive and has the following drawbacks: uneven burrs require die disassembly for replacement or repair; the lower die assembly of the track link forging die is not quick to replace, causing inconvenience to workers, increasing die replacement time, and consequently affecting the efficiency of die replacement and maintenance, thus delaying the normal production and processing of track links. To solve one of the above problems, an adjustable mold base is urgently needed. Utility Model Content
