Description

Technical Field

[0001] The utility model relates to an integral forging die for a main track link, belonging to the technical field of main track link production. Background Art

[0002] The track link is an important component in the crawlers of construction machinery such as bulldozers and excavators, and the market demand is very large. The track link works in a harsh environment, with complex forces, and needs to bear a large random alternating load during working conditions. It is one of the most easily failed components in the walking system of crawler construction machinery.

[0003] The processing process of the track link includes die forging and forming, which needs to be carried out on a die forging and forming machine. Each time a forging is produced, a mold release agent is sprayed and cooled on the mold. The mold release agent is evenly sprayed on the upper and lower die cavities, reducing the thermal stress and thermal fatigue of the mold and facilitating demolding.

[0004] At present, during the production of track links, the inner cavity of the mold is generally sprayed with a mold release agent manually. This manual spraying method not only wastes manpower and material resources, but also has low spraying efficiency, is prone to uneven spraying or low spraying quality, resulting in liquid accumulation, affecting the shaping of the product.

[0005] The utility model with the patent number CN202121881143.X discloses an automatic mold spraying device for track link forging, including a mold release agent dissolution tank. A feeding port is installed at the top of the mold release agent dissolution tank, a stirring device is installed inside the mold release agent dissolution tank, and a liquid outlet is provided at the bottom of the mold release agent dissolution tank. The lower die mold release agent spray head is installed on the upper die of the track link die forging and forming machine, spraying obliquely upward, and the upper die mold release agent spray head is installed on the lower die of the track link die forging and forming machine, spraying obliquely downward.

[0006] Although the above patent can achieve the function of spraying the mold release agent, the current technology has incomplete considerations and has the following drawbacks: both the lower die mold release agent spray head and the upper die mold release agent spray head are fixed on the upper die and the lower die respectively by a fixed installation method. The lower die mold release agent spray head and the upper die mold release agent spray head can only spray obliquely upward or obliquely downward, and there are still problems of small spraying range and uneven spraying.

[0007] To solve one of the above problems, there is an urgent need for an integral forging die for a main track link. Summary of the Utility Model

[0008] According to the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to use a double-end cylinder as a power source to drive the intermediate support column to reciprocate between the left vertical support column and the right vertical support column, increasing the spraying range of the upper die mold release agent spray head and the lower die mold release agent spray head. For this purpose, an integral forging die for a main track link is provided.

[0009] The one-piece forging die of the main chain track section described in the utility model includes a hydraulic forging machine body provided with an upper die and a lower die. The upper die and the lower die cooperate with each other and are arranged oppositely. The lower die is installed on the workbench of the hydraulic forging machine body. It is characterized in that: it further includes a horizontally arranged support platform. One end of the support platform is installed on the workbench of the hydraulic forging machine body, and the other end has a left support column supported on the ground. A horizontal track and a movable track trolley are arranged along the length direction of the support platform. The movable track trolley is installed on the horizontal track and can move along its length direction on it. The movable track trolley is installed with a connecting pipe through a crossbeam mounting seat. One end of the connecting pipe away from the crossbeam mounting seat is suspended and is installed with an upper die release agent spray head and a lower die release agent spray head. The upper die release agent spray head and the lower die release agent spray head spray towards the upper die and the lower die respectively.

[0010] First, drive the crossbeam mounting seat to move through the movable track trolley. The crossbeam mounting seat drives the connecting pipe to move, so that the upper die release agent spray head and the lower die release agent spray head on the connecting pipe move between the upper die and the lower die. The connecting pipe is connected to a release agent supply unit through a supply pipe. The release agent supply unit is a conventional structure. The release agent is supplied to the upper die release agent spray head and the lower die release agent spray head through the connecting pipe and is sprayed out through the upper die release agent spray head and the lower die release agent spray head.

[0011] For each forging produced, the die is sprayed with release agent for cooling once. The release agent is evenly sprayed on the upper and lower forging cavities, reducing the thermal stress and thermal fatigue of the die and facilitating demolding.

Then, turn on the upper die release agent spray head and the lower die release agent spray head. At the same time, using a double-headed cylinder as the power source, drive the middle support column to reciprocate between the left vertical support column and the right vertical support column, increasing the spraying range of the upper die release agent spray head and the lower die release agent spray head. Compared with the traditional spraying method where the lower die release agent spray head and the upper die release agent spray head are fixedly installed, the spraying range is larger and the spraying is more uniform.

[0015] After spraying is completed, turn off the upper die release agent spray head, the lower die release agent spray head and the double-headed cylinder.
