Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a track wheel forging device and process. Background Art

[0002] The track roller is an important part of the chassis of engineering machinery and is widely used in various engineering machinery such as excavators, bulldozers and special machinery. Generally speaking, the track roller mainly transfers the weight of the locomotive group to the ground and rolls on the track. Traditional track roller forging mostly adopts high-temperature pressure forging and pressure punching to directly form the track roller, followed by conventional cooling or quenching. At present, the process of processing track rollers is to heat the track roller blank from room temperature to 820-860 degrees and then water-cool it. This heating process consumes a lot of electricity, has high requirements for the operation of the heating process, a long cycle, low work efficiency, high energy consumption, and there will be certain defects on the surface of the workpiece after processing, which affects the yield and service life of the overall track roller.

[0003] The Chinese patent document publication number CN115138797B is an integrated forging method and forging device suitable for supporting wheels, wherein the forming method includes the following steps: S100, heating the supporting wheel billet to a predetermined temperature; S200, removing the oxide scale on the surface of the heated billet, and ensuring that the temperature of the billet after the oxide scale is removed is maintained at 1100°C to 1200°C; S300, transferring the billet at a temperature of 1100°C to 1200°C to the lower die seat of the mold; S400, moving the upper die seat downward at a predetermined first speed, and after a predetermined delay, controlling the two side die seats to synchronously approach and extrude the billet at a predetermined second speed to form a supporting wheel inner cavity with a skin, wherein the first speed is 1.5 to 4 times the second speed; S500, opening the mold, and removing the skin in the supporting wheel inner cavity when the temperature is greater than or equal to 800°C. However, this patent still has some shortcomings: after removing the skin in the inner cavity of the roller, it needs to be transferred to the heat treatment station. During this process, the roller gradually cools down, which not only wastes a lot of residual heat, but also when the completely cooled roller is reheated to the heat treatment temperature, it is easy to have coarse grains, which will also affect the overall mechanical properties of the roller.

A forging process for a track wheel, characterized in that: The roller forging device according to claim 5 further comprises the following process: S1, raw material cutting, cutting the round bar raw material into round bars of specified length by the round bar cutting device (1); S2, heating before forging, heating the round bar material to a temperature required for forging by means of a furnace body (22) of a heating device (3); S3, bar stock blanking, pre-forging the heated round bar stock by a pre-forging blanking device (4), and forging the round bar stock into a pre-forged blank; S4, surface dephosphorization, the formed pre-forged billet is sent into a dephosphorization machine (2) by a first manipulator (10), and the dephosphorization machine (2) removes the oxide scale on the surface of the pre-forged billet; S5, final forging of the track wheel, placing the pre-forged blank from which the oxide scale has been removed into the final forging device (5) by means of the first manipulator (10) for final forging, and forging the pre-forged blank into a track wheel blank with a closed inner hole at the axis; S6, punching, moving the roller blank forged in the final forging device (5) to the punching device (6) by means of the second manipulator (11), and the punching device (6) punches a hole at the axis of the roller blank so that the axis of the roller blank is penetrated; S7, heating the blank, moving the roller blank that has not been completely cooled after punching to the supplementary heating device (7) through the third manipulator (12), and the supplementary heating device (7) heats the roller blank again to raise the temperature of the roller blank to the heat treatment temperature; S8, surface heat treatment, the third manipulator (12) moves the heated roller blank to the heat treatment device (8) and fixes it on the top (13), then sprays quenching liquid on the roller blank through the sprayer (14) for quenching. After quenching, the roller blank is placed into the material frame (9) through the third manipulator (12).
