Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting and rolling technology, specifically to an aluminum alloy casting and rolling equipment structure for online feeding of aluminum alloy plates and strips. Background Technology

[0002] Currently, aluminum casting and rolling equipment typically employs manual loading with auxiliary tools. The loading process mainly involves pinch rollers driving the aluminum alloy strip billet head, with the operator using tools to lift the billet head and guide it into the coiling frame's expansion and contraction clamping port. Once the billet head is fully inside the clamping port, the coiling shaft is tightened to restore mill tension, securing the billet head and completing the loading process. A major problem is that manual lifting of the billet head is prone to misalignment, resulting in the billet head not entering the clamping port, necessitating recutting. The cut-off aluminum alloy strip billet head then needs to be transported by crane, creating redundant workload. During processing, the aluminum coil needs to be mounted on the coiling expansion and contraction shaft clamping port; currently, this operation is also done manually, resulting in low production efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1-3 As shown, an aluminum alloy cast and rolled strip guiding device includes a base 1, a support roller bracket 2, a support roller 4, a deflector roller bracket 5, a deflector roller 6, a feeding guide plate bracket 7, a feeding guide plate 8, and a lifting mechanism.

[0021] A support roller bracket 2 is located at the front of the base 1. A support roller 4 is horizontally mounted on the support roller bracket 2. Support roller shafts 3 are located at both ends of the support roller 4, which are mounted on the support roller bracket 2. The support roller 4 can rotate freely on the support roller bracket 2, allowing the aluminum alloy strip to smoothly receive the strip after processing by the shearing machine and move forward smoothly on the support roller 4. A guide roller bracket 5 is located on the base 1, between the support roller bracket 2 and the feed guide plate bracket 7. A guide roller 6 is horizontally mounted on the guide roller bracket 5. The top of the guide roller 6 is higher than the top of the support roller 4, used to raise the height of the aluminum alloy strip, allowing the high-strength aluminum alloy strip to move smoothly and rest on the front end of the feed guide plate 8. The guide roller 6 can rotate freely, ensuring that the aluminum alloy strip can continue to move forward smoothly. The length of the support roller 4 and the guide roller 6 is greater than the length of the coiler's expansion and contraction shaft, ensuring that the aluminum alloy strip can be processed as a whole on the coiler.

[0022] The base 1 is equipped with a material guide plate bracket 7, which is located behind the support roller bracket 2. A material guide plate 8 is mounted on the material guide plate bracket 7, and is inclined with its front end higher than its rear end. A through hole 801 is provided on the material guide plate 8. Two protrusions are located on the rear side of the base 1, with the top surface of the protrusions lower than the top surface of the base 1. Lifting mechanisms are connected to both protrusions, symmetrically distributed on the left and right sides of the center line of the base 1. Each lifting mechanism includes a hydraulic cylinder 905, a piston rod 904, an auxiliary roller bracket 903, and an auxiliary roller 901. The hydraulic cylinder 905 is connected to the base 1, and the piston rod 904 is connected to the hydraulic cylinder 905. The end of the stopper rod 904 is connected to an auxiliary roller bracket 903. An auxiliary roller 901 is installed on the auxiliary roller bracket 903. Auxiliary roller shafts 902 are provided at both ends of the auxiliary roller 901. The auxiliary roller shafts 902 are rotatably connected to the auxiliary roller bracket 903. The auxiliary roller 901 can rotate freely on the auxiliary roller bracket 903. The auxiliary roller 901 extends out of the through hole 801. The piston rod 904 is driven by the hydraulic cylinder 905 to make the auxiliary roller 901 extend upward or retract downward from the through hole 801, thereby changing the height of the auxiliary roller 901 at the top of the piston rod 904, thus changing the height of the aluminum alloy strip traveling on the auxiliary roller 901, so that the aluminum alloy strip can smoothly enter the gap of the coiler's expansion shaft.

[0023] The center line of base 1, the midpoint of support roller 4, the center line of feed guide plate 8, the center line of feed guide plate bracket 7, and the midpoint of the winding machine expansion shaft are all on the same vertical plane, which further improves the stability, practicality, and reliability of the device.

[0024] Example 2

[0025] like Figure 4 As shown, based on Embodiment 1, a centering mechanism is provided on the base 1 for pushing the aluminum alloy strip left and right. The adjusting head support frame 1003 is located on the left and right sides of the feeding guide plate bracket 7. The centering mechanism includes the adjusting head support frame 1003, the rotating screw 1002, the adjusting head 1001, and the transmission motor 1004. The adjusting head support frame 1003 is located on the left and right sides of the base 1. The rotating screw 1002 is passed through the bracket. The two rotating screws 1002 are each provided with an adjusting head 1001 at their opposite ends. The adjusting head 1001 includes a pushing part and a connecting part. The pushing part is a vertically arranged circular plate. The pushing part is connected to the spiral screw through the connecting part. The pushing part, the connecting part, and the central axis of the spiral screw are on the same straight line. The transmission motor 1004 is provided on the side of the adjusting head support frame 1003. The rotating screw 1002 is connected in the transmission motor 1004. The screw is driven by the drive motor 1004, which causes the adjusting head 1001 at the end of the screw to push the aluminum alloy strip in the horizontal direction, so that the center line of the aluminum alloy strip is aligned with the midpoint of the winding machine's expansion shaft when the aluminum alloy strip enters the winding machine's expansion shaft.

[0026] The method of using this utility model is as follows:

[0027] Step 1: According to the model and size of the casting and rolling mill, manufacture an online transmission device for aluminum alloy casting and rolling strip. Install the manufactured device in front of the coiler and correct its position so that the center line of the base 1, the midpoint of the support roller 4, the center line of the feeding guide plate 8, the center line of the feeding guide plate bracket 7, and the midpoint of the coiler expansion shaft are all in the same vertical plane.

[0028] Step 2: The casting and rolling mill starts producing aluminum alloy strip. After the aluminum alloy strip end is sheared by the shearing machine, it automatically moves above the support roller 4. When the aluminum alloy strip end is transported above the deflector roller 6, the position and status of the slab are monitored in real time by the sensor. When the position of the aluminum alloy strip deviates and the center line deviates from the center line of the feeding guide plate 8, the centering mechanism is activated. The centering mechanism is adjusted left and right to correct the position of the aluminum alloy strip. The motor 1004 drives the lead screw 1002 to move, which drives the adjusting head 1001 to push the aluminum alloy strip left and right to ensure that the center line of the aluminum alloy strip is aligned with the midpoint of the coiler's expansion and contraction shaft.

[0029] Step 3: The aluminum alloy strip continues to advance and reaches above the feeding guide plate 8. Adjust the hydraulic cylinder 905 to drive the auxiliary roller 901 to lift the aluminum alloy strip, so that the end of the aluminum alloy strip smoothly enters the gap of the coiler's expansion and contraction shaft. Then, start the hydraulic cylinder 905 to lower the piston rod 904, which drives the auxiliary roller 901 to descend. The rotating expansion and contraction shaft works with tension, so that the aluminum alloy strip is completely separated from this utility model. The lower surface of the aluminum alloy strip is no longer in contact with the support roller 4, the deflector roller 6, the feeding guide plate 8, and the auxiliary roller 901, thus completing the winding of the aluminum alloy strip.

[0030] The above description is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
