Description

A support roller forging equipment and process Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a forging equipment and process for support rollers. Background Technology

[0002] Track rollers are crucial components of construction machinery chassis, widely used in various construction machines such as excavators, bulldozers, and special-purpose machinery. Generally, track rollers primarily transfer the weight of the vehicle assembly to the ground and roll along the tracks. Traditional track roller forging often involves high-temperature pressure forging and pressure punching followed by conventional cooling or quenching. Currently, track roller machining involves heating the blank from room temperature to 820-860°C and then water-cooling it. This heating process consumes a significant amount of electrical energy, requires highly skilled operation, has a long cycle time, low efficiency, and high energy consumption. Furthermore, the surface of the workpiece may have certain imperfections after machining, affecting the overall yield and service life of the track roller.

[0003] Chinese Patent Publication No. CN115138797B discloses an integral forging method and forging apparatus for support rollers, wherein the forming method includes the following steps: S100, heating the support roller steel billet to a predetermined temperature; S200, removing the oxide scale from the surface of the heated steel billet and ensuring that the temperature of the steel billet after oxide scale removal is maintained at 1100℃~1200℃; S300, transferring the steel billet at the temperature of 1100℃~1200℃ to the lower die holder of the mold; S400, moving the upper die holder downward at a predetermined first speed, and after a predetermined delay, controlling the two side die holders to synchronously approach and squeeze the steel billet at a predetermined second speed to form a support roller cavity with a connecting skin, wherein the first speed is 1.5 times to 4 times the second speed; S500, opening the mold, and removing the connecting skin in the support roller cavity at a temperature greater than or equal to 800℃. However, the patent still has some shortcomings: after removing the skin from the inner cavity of the support roller, it needs to be transferred to the heat treatment station. During this process, the support roller gradually cools down, which not only wastes a lot of residual heat, but also tends to have coarse grains when the support roller is reheated to the heat treatment temperature after it has been completely cooled, which will also affect the overall mechanical properties of the support roller. Summary of the Invention

[0004] To address the technical problem that traditional machining processes for track rollers easily result in coarse grains that affect the overall mechanical properties of the track rollers, this invention provides a track roller forging equipment and process to solve the above problems.

[0012] A support roller forging process includes the aforementioned support roller forging equipment, and further includes the following processes:

[0013] S1. Raw material cutting: The round bar raw material is cut into round bars of a specified length using a round bar cutting device;

[0014] S2. Pre-forging heating: The round bar is heated to the temperature required for forging through the furnace body of the heating device;

[0015] S3. Bar stock preparation: The heated round bar stock is pre-forged into a pre-forged billet using a pre-forging billet preparation device.

[0021] The beneficial effects of this invention are as follows: By incorporating a reheating device and a heat treatment device, the round bar stock, after being heated and manufactured into a support roller blank, is not completely cooled. At this point, the uncooled support roller blank is reheated using the reheating device, effectively reducing waste of residual heat and allowing the punched support roller blank to quickly reach the temperature required for heat treatment. Then, the heat treatment device's sprayer evenly sprays quenching liquid onto the heated support roller blank, reducing the time required for the quenching process. Utilizing forging residual heat for quenching preserves the material's structural fibers and prevents grain growth after recrystallization. After tempering, its strength and toughness are significantly improved compared to performance obtained through traditional methods of cooling and then reheating. Attached Figure Description

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] As shown in Figures 1 to 6, the present invention provides an embodiment of a support roller forging equipment and process, including a round bar cutting device 1 and a descaling machine 2.

The round bars cut by the round bar cutting device are transported to the pusher feeder 15 via a trolley. 5. The round bar is then lifted and fed into the inlet end of the conveying track 16. The bar is then transported by the conveying track 16 to the unloading tray 18. The piston rod of the unloading cylinder 17 extends to push the round bar off the conveying track 16 and onto the unloading tray 18. Finally, the piston rod of the push cylinder 19 extends to push the round bar into the furnace body 22 and heats it to the temperature required for forging. After forging, the round bar is pushed out of the furnace body 22 by the push cylinder 19 and enters the discharge track 20.

The induction heating coil 26 is used to heat the support roller blank. The rotating table 25 drives the central support base 24 and the support roller blank to rotate, so that the various parts of the support roller blank are heated more evenly.

[0038] The heat treatment device 8 includes a center 13 and a sprayer 14. A third robotic arm 12 moves the heated support roller blank to the center 13 for support and fixation. The heat treatment device 8 includes a horizontal shaft seat 27, a telescopic cylinder 28, and a horizontal shaft 29. The horizontal shaft 29 is horizontally slidably installed within the horizontal shaft seat 27. The center 13 is fixed to the front end of the horizontal shaft 29 and is used to clamp the support roller blank. The telescopic cylinder 28 is fixed to the side of the horizontal shaft seat 27. The piston rod is connected to the rear end of the horizontal shaft 29 through a connector. The telescopic cylinder 28 is used to drive the horizontal shaft 29 to extend or retract. The sprayer 14 has a cylindrical structure and is mounted in front of the horizontal shaft 29 in the direction of extension.

Then, the support roller blank on the transfer platform 35 is moved to the heating device 7 for heating by the third robot arm 12. Since the heating of the heating device 7 takes a long time, while the punching time is short, by setting up the transfer platform 35 in the middle, the punching device 6 can carry out production without waiting for subsequent stations, thereby enabling better connection between stations and improving the overall production line efficiency. Quenching with residual heat from forging can preserve the material's structural fibers and prevent grain growth after recrystallization.
