Description

Technical Field

[0001] The utility model relates to a split lower die seat for forging a track link, and belongs to the technical field of forging dies for track links. Background Art

[0002] Track links are important parts in the crawler tracks of construction machinery such as bulldozers and excavators, and the market demand is huge. Track links work in harsh environments, are subject to complex forces, and need to withstand large random alternating loads during working conditions. They are one of the parts that are most prone to failure in the walking system of crawler-type construction machinery.

[0003] The processing steps of the track link include die forging and press forming, which needs to be carried out on a die forging machine.

[0004] After searching, the patent application is CN202122081198.9, which discloses a composite die for precision cutting of track segments, which can solve the above problems. While using the composite die to precision cut the track segments after final forging, it also completes the processes of cutting flash, punching, and shaping, realizes the automation of the trimming process, and greatly improves the forging efficiency. However, there are still problems in use. For example, after the die is assembled, the position of the upper and lower die for trimming cannot be adjusted during the forging process. During the forging process, when the upper and lower die seats are seriously misaligned, the residual flash on one side of the forging after trimming is large, and the residual flash on the other side is small or even cuts into the surface of the forging, which not only affects the surface quality of the forging, but also increases the workload of rework. Excessive residual flash on the nut surface will cause interference between the track segment and the track plate after assembly, affecting the use of the track. When uneven trimming occurs, the die needs to be removed for replacement or rework. The whole process takes about 3-5 hours, which seriously affects production efficiency.

[0005] In order to solve one of the above problems, a split lower die base for forging a track link is urgently needed. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: how to achieve fine-tuning or replacement of the lower die assembly body, and for this purpose, a split lower die seat for forging a track segment is provided.

[0008] The present application is placed on the upper surface of the T-slot workbench and fixed by the T-bolts on the workbench and the U-slots. The length direction adjustment and locking mechanism can be used to clamp and lock the lower mold body after fine-tuning its length direction position, and the width direction adjustment and locking mechanism can also be used to clamp and lock the lower mold body after fine-tuning its width direction position. After the fine-tuning is completed, the lower mold body is detachably fixed to the upper surface of the horizontal substrate through the main connection mechanism to limit the lower mold body from being separated from the horizontal substrate. Fine-tuning or rapid replacement of the lower mold body can be achieved.

[0009] Preferably, at least two groups of U-shaped grooves are respectively formed on the front and rear side edges of the horizontal substrate.
