Description

Technical Field

[0001] This utility model relates to the field of finishing mill rolling line production technology, and in particular to a finishing mill rolling line correction mechanism. Background Technology

[0002] During the finishing mill rolling process, sheet metal is prone to edge deviation from the preset rolling line due to problems such as uneven mill side pressure, material inlet position deviation, and fluctuations in conveyor roller accuracy. Traditional finishing mill rolling line correction methods mostly use rigid adjustment structures such as lead screws and worm gears, which have significant limitations: rigid transmission is prone to causing scratches and indentations on the sheet metal edges, especially for thin sheets or sheets with high surface precision requirements, resulting in a high damage rate. Therefore, there is an urgent need to develop a finishing mill rolling line correction mechanism that can conveniently detect and correct the edge position of finishing mill sheet metal in real time, and whose first and second elastic expansion airbags are made of silicone rubber, working in conjunction with polyurethane rollers to push the sheet metal edge for flexible adjustment, avoiding the scratches and indentations caused by traditional rigid adjustments. This would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a straightening mechanism for a finishing mill rolling line to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A straightening mechanism for a finishing mill rolling line includes a gantry, a flexible straightening mechanism, laser position sensors, and a PLC controller. The flexible straightening mechanism is mounted on the gantry. Two laser position sensors are fixed to the left and right sides of the gantry's interior, respectively. The flexible straightening mechanism includes: a first elastic expansion airbag, a first conduit, a first solenoid valve, a second elastic expansion airbag, a second conduit, a second solenoid valve, a transition frame, polyurethane rollers, a limit rod, a spring, a bidirectional high-pressure air pump, and a tee connector. The first elastic expansion airbag is fixed to the left side of the gantry's interior, the second elastic expansion airbag is fixed to the right side, and the bidirectional high-pressure air pump is fixed to the top of the gantry. A three-way connector is connected to the high-pressure air pump. The first elastic inflatable airbag is connected to the three-way connector through a first conduit. A first solenoid valve is installed on the first conduit. The second elastic inflatable airbag is connected to the three-way connector through a second conduit. A second solenoid valve is installed on the second conduit. Adapter frames are respectively provided on the front sides of the first and second elastic inflatable airbags. Multiple polyurethane rollers are rotatably connected to the front side of each adapter frame. Multiple limiting rods penetrating the gantry frame are fixed on the rear side of each adapter frame. The limiting rods slide in contact with the gantry frame. A spring is installed on the outer side of each limiting rod. One end of the spring is fixed to the limiting rod and the other end is fixed to the gantry frame.

[0006] Preferably, both the first and second elastic inflatable airbags are made of silicone rubber.

[0007] Preferably, a PLC controller is fixedly installed on the side of the gantry frame.

[0008] Preferably, the laser position sensor, the first solenoid valve, the second solenoid valve, and the bidirectional high-pressure air pump are all electrically connected to and controlled by the PLC controller.

[0009] The beneficial effects of this utility model are as follows: When in use, the finishing mill rolling line correction mechanism uses a laser position sensor to detect the edge position of the finished plate in real time and transmits the detection data to the PLC controller. When the detection data exceeds the standard value range, the PLC controller controls the flexible correction mechanism to adjust the edge position of the finished plate. When it is necessary to move the edge position of the finished plate to the right, the first solenoid valve is opened, the second solenoid valve is closed, and a bidirectional high-pressure air pump is started to inflate the first elastic expansion airbag. The inflated first elastic expansion airbag compresses the adapter frame, causing the adapter frame to drive the polyurethane roller forward. The polyurethane roller pushes the edge of the finished plate to the right. Simultaneously, the position is detected in real time by the laser position sensor. After pushing to the correct position, the first elastic expansion airbag is deflated, causing the adapter frame and polyurethane roller to return to their original positions. Similarly, the edge of the finished plate can be pushed to the left by the expansion of the second elastic expansion airbag. In summary, this utility model provides convenient real-time detection and correction of the edge position of precision rolled plates. Furthermore, the first and second elastic expansion airbags are made of silicone rubber and work with polyurethane rollers to push the edge of the plate for flexible adjustment, avoiding scratches, indentations, and other damage to the plate caused by traditional rigid adjustment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] See Figures 1-4 In this embodiment of the utility model, the finishing mill rolling line correction mechanism includes a gantry frame 1, a flexible correction mechanism 2, a laser position sensor 3, and a PLC controller 4. The gantry frame 1 is fixed on the ground, and the finishing mill rolling line passes through the underside of the gantry frame 1. The flexible correction mechanism 2 is installed on the gantry frame 1. There are two laser position sensors 3, which are fixed on the left and right sides inside the gantry frame 1 respectively. The edge position of the finishing mill plate is detected by the two laser position sensors 3, and the flexible correction mechanism 2 is used to correct the edge position of the finishing mill plate.

[0019] The flexible correction mechanism 2 includes: a first elastic inflation airbag 201, a first conduit 202, a first solenoid valve 203, a second elastic inflation airbag 204, a second conduit 205, a second solenoid valve 206, an adapter frame 207, a polyurethane roller 208, a limiting rod 209, a spring 210, a bidirectional high-pressure air pump 211, and a three-way connector 212. The first elastic inflation airbag 201 is fixed inside the left side of the gantry frame 1, the second elastic inflation airbag 204 is fixed inside the right side of the gantry frame 1, and the bidirectional high-pressure air pump 211 is fixed to the top of the gantry frame 1. The bidirectional high-pressure air pump 211 can both inflate and deflate air. A three-way connector 212 is connected to the bidirectional high-pressure air pump 211. The first elastic inflatable airbag 201 is connected to the three-way connector 212 via a first conduit 202, on which a first solenoid valve 203 is installed. The second elastic inflatable airbag 204 is connected to the three-way connector 212 via a second conduit 205, on which a second solenoid valve 206 is installed. Adapters are respectively provided on the front sides of the first elastic inflatable airbag 201 and the second elastic inflatable airbag 204. Each adapter frame 207 has multiple polyurethane rollers 208 rotatably connected to its front side, and multiple limiting rods 209 penetrating the gantry frame 1 are fixed to the rear side of each adapter frame 207. The limiting rods 209 slide in contact with the gantry frame 1, and a spring 210 is installed on the outer side of each limiting rod 209. One end of the spring 210 is fixed to the limiting rod 209, and the other end is fixed to the gantry frame 1. When it is necessary to move the edge of the precision rolled plate to the right, the first solenoid valve 203 is opened, the second solenoid valve 206 is closed, and the bidirectional high-speed operation is activated. The air pump 211 inflates the first elastic expansion airbag 201. The inflated first elastic expansion airbag 201 compresses the adapter frame 207, causing the adapter frame 207 to drive the polyurethane roller 208 forward. The polyurethane roller 208 pushes the edge of the precision rolled plate to the right. At the same time, the position is detected in real time by the laser position sensor 3. After pushing to the correct position, the first elastic expansion airbag 201 is deflated, so that the adapter frame 207 and the polyurethane roller 208 return to their original positions. Similarly, the edge of the precision rolled plate can be pushed to the left by the expansion of the second elastic expansion airbag 204.

[0020] Both the first elastic inflatable airbag 201 and the second elastic inflatable airbag 204 are made of silicone rubber, giving them good elasticity.

[0021] A PLC controller 4 is fixedly installed on the side of the gantry frame 1. The laser position sensor 3, the first solenoid valve 203, the second solenoid valve 206, and the bidirectional high-pressure air pump 211 are all electrically connected to and controlled by the PLC controller 4. The standard value range of the edge position of the precision rolled plate is pre-input into the PLC controller 4. The laser position sensor 3 transmits the detection data to the PLC controller 4. When the detection data exceeds the standard value range, the PLC controller 4 controls the flexible correction mechanism 2 to adjust the edge position of the precision rolled plate.

[0022] Working Principle: During operation, the finishing mill line correction mechanism uses a laser position sensor 3 to detect the edge position of the finished plate in real time and transmits the data to a PLC controller 4. When the detected data exceeds the standard value range, the PLC controller 4 controls the flexible correction mechanism 2 to adjust the edge position of the finished plate. When the edge position of the finished plate needs to be moved to the right, the first solenoid valve 203 is opened, the second solenoid valve 206 is closed, and the bidirectional high-pressure air pump 211 is started to inflate the first elastic expansion airbag 201. The inflated first elastic expansion airbag 201 compresses the adapter frame 207, causing the adapter frame 207 to drive the polyurethane roller 208 forward. The polyurethane roller 208 pushes the edge of the finished plate to the right. Simultaneously, the laser position sensor 3 detects the position in real time. After pushing to the correct position, the first elastic expansion airbag 201 is deflated, causing the adapter frame 207 and the polyurethane roller 208 to return to their original positions. Similarly, the edge of the finished plate can be pushed to the left by the expansion of the second elastic expansion airbag 204.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
