Description

Technical Field

[0001] This utility model belongs to the field of steel ring plate production technology, and specifically relates to a hydraulic three-roll symmetrical plate rolling machine. Background Technology

[0002] In normal operation of existing hydraulic three-roll symmetrical plate rolling machines, gear wear often leads to a decrease in the fit between gears and chains, resulting in vibration, chain skipping, tooth skipping, tooth chipping, and excessive noise. Failure to repair in a timely manner can lead to the production of defective products and sudden equipment shutdowns. Routine maintenance methods, such as chain cutting, require the removal of two chain links in pairs, resulting in a chain that is too short to reconnect. Replacing gears requires the use of large lifting equipment such as forklifts and overhead cranes, resulting in a large workload, long repair time, and severely impacting the production line's capacity.

Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figure 1-4 A hydraulic three-roll symmetrical plate rolling machine includes a frame 5. One upper roller 2 and two lower rollers 1 are mounted on the frame 5. The upper roller 2 is positioned above the two lower rollers 1. Both ends of the upper roller 2 and the lower rollers 1 are connected to bearing seats mounted on the frame 5. A drive mechanism is mounted on the frame 5 to drive the two lower rollers to rotate. A sprocket I 8 is mounted on the output shaft of the drive mechanism, and a sprocket II 7 is mounted on one end of each lower roller. The sprocket II 7 is connected to the sprocket I 8 via a chain 10.

[0021] A connecting plate 9 is installed at one end of each lower roller 1. The roller end of the lower roller 1 passes through the bearing provided on the connecting plate 9 and connects with the bearing seat on the frame 5. The sprockets II 7 and I 8 are both located on the outside of the connecting plate 9.

[0022] A lateral adjustment mechanism that cooperates with the chain is installed on the connecting plate 9. The lateral adjustment mechanism includes a mounting plate 12 fixed on the connecting plate 9 and an adjustment wheel 11 pressed against the outside of the chain. The mounting plate 12 has a lateral adjustment elongated hole 13. The wheel axle of the adjustment wheel 11 is connected to a sliding seat provided in the lateral adjustment elongated hole 13 through a bearing. A screw 14 for adjusting the position of the sliding seat is provided on the mounting plate 12. The screw 14 is threadedly connected to the sliding seat. Both ends of the screw 14 are connected to the bearings provided on the mounting plate.

[0023] A flipping mechanism is provided at one end of the upper roller 2 to facilitate the removal of the steel cylinder from the upper roller, and a counterweight mechanism is installed at the other end of the upper roller to increase the pressure on the steel cylinder.

[0024] The flipping mechanism includes a flipping frame 3 and a flipping drive cylinder 4 connected to the flipping frame 3. The bottom of the flipping frame 3 is hinged to the machine frame, and the flipping drive cylinder 4 is located on the machine frame outside the flipping frame 3. A bearing seat that mates with the end of the upper roller 2 is installed on the flipping frame 3. The bearing and bearing seat are sleeved onto the end of the upper roller to facilitate separation of the bearing from the upper roller. After the steel cylinder is pressed and formed, it needs to be removed from between the upper and lower rollers. Under the action of the flipping drive cylinder, the flipping frame is flipped outward, thereby separating the flipping frame from the end of the upper roller. Then, the steel cylinder is removed from the end where the flipping frame is located, the flipping frame is reset, and the operation continues.

[0025] The counterweight mechanism includes several counterweight blocks and a counterweight frame for placing the counterweight blocks. The counterweight frame is suspended at the end of the upper roller by a rope. The number of counterweight blocks can be increased or decreased according to the pressing requirements of the steel cylinder, thereby controlling the pressing force.

[0026] The adjusting wheel 11 is an adjusting sprocket, and the sprocket and the chain are engaged by gears.

[0027] A gap of 15mm is provided between the connecting plate 9 and the sprocket II 7 for accommodating the lateral adjustment mechanism. This gap prevents the transmission chain from swaying laterally during operation and allows for free adjustment of the chain length. It effectively solves problems such as vibration, chain skipping, tooth skipping, tooth wear, and excessive noise caused by a decrease in the fit between the gear and the chain, reducing maintenance workload and improving production efficiency.

[0028] When the fit between the gears and the chain decreases, the position of the adjusting wheel is adjusted by the screw to tighten the loose chain, thus effectively solving problems such as vibration, chain skipping, tooth skipping, tooth wear, and excessive noise caused by the decreased fit between the gears and the chain.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
