Description

Technical Field

[0001] The utility model relates to the technical field of hot bending of steel plates, in particular to a hot bending heating production line for steel plates. Background Art

[0002] Steel plates need to be heated first when they are processed into arcs or need to be bent and deformed. The main reason for heating is to increase the plasticity of the material and make it easier to change. The internal structure of the steel plate is softened by heating, making it easier to make complex shape changes without causing material cracks. The traditional way to heat steel plates is to put the steel plates in a furnace. The furnace needs to be burning all the time to meet daily production needs, which leads to excessive energy consumption and waste, and it is difficult to achieve local heating.

One roller is composed of a heat-resistant and heat-insulating corundum roller and is installed below the heating device 3. The other roller is stainless steel and is installed outside the heating device 3. The heating device 3 includes an insulation cover 301, and an electromagnetic induction heating ring 30 is installed at the bottom of the insulation cover 301. 2. The electromagnetic induction heating rings 302 are divided into several groups and staggeredly installed. The width of each group is designed to be roughly within a range according to the specific heating width of the steel plate, so as to accurately control the heating width according to the width of the steel plate and save resources. The lifting device 2 includes four electric cylinders and four support rods. The electric cylinders are installed at a position close to the ground and away from the heating device 3. The support rods are vertically upward and pushed up and down by the electric cylinders to change the distance between the heating device 3 and the roller of the roller conveyor line 1. A centering device 4 is installed in front of the roller conveyor line 1. The centering device 4 includes a bracket 401, a straight The guide rail 402, the shift fork 403, the electric push rod 404 and the wide-angle camera 405. When the electric push rod 404 is working, it pushes the shift fork 403 to move under the linear guide rail 402 to push the steel plate to the middle position. When the wide-angle camera 405 is working, it takes a picture of the position of the steel plate to determine whether it has been centered. A control console 5 and a heating host 6 are set on one side of the roller conveyor line 1. The control console 5 is used to control the movement of various components of the entire production line. The control console 5 stores comparison photos of steel plates of various widths to determine whether the corresponding steel plates have been centered.

The sensing signal of the infrared ranging sensor 7 passes through the rollers on the roller conveyor line 1, that is, when the steel plate is not transported to the bottom of the infrared ranging sensor 7, the detected distance is very long, and when the steel plate is transported to the bottom of the infrared ranging sensor 7, the detected distance is very short. The distance change detected by the infrared ranging sensor 7 can be used to determine whether the steel plate has been transported to the bottom of the heating device 3.

[0024] When in use, firstly, electromagnetic induction heating rings 302 of different specifications are made according to the size of the steel plate to be heated and are staggeredly installed under the heat insulation cover 301, and each electromagnetic induction heating ring 302 is required to cooperate with each other to take into account the sizes of various specifications of steel plates as accurately as possible when heating. Before the first heating, the steel plates of various specifications are first placed on the roller conveyor line 1 and centered by the centering device 4, and then the wide-angle camera 405 takes pictures and stores them in the control console 5, and then the control console 5 uses the photos taken back as reference photos of this type of steel plate to determine whether this type of steel plate has been centered, and each type of steel plate control console 5 will correspond to a set of heating processes according to its heating requirements.

If it is not centered, the electric push rod 404 continues to push the steel plate repeatedly and synchronously from both sides. When the steel plate is centered, the roller conveyor line 1 transports it to the bottom of the heating device 3, and further the lifting device 2 works to move the heating device 3 downward and close to the steel plate, and further the electromagnetic induction heating ring 302 works to heat the steel plate below. At the same time, the roller conveyor line 1 transports the steel plate back and forth and cooperates with the start and stop time of each electromagnetic induction heating ring 302 to control the area where the steel plate is heated. The position of the steel plate moving under the heating device 3 is monitored by the infrared ranging sensor 7 and controlled by the distance of the roller conveyor line 1. When the steel plate is heated, it is sent out from the other end of the roller conveyor line 1.

[0025] To summarize, the steel plate hot bending heating production line can push the steel plate to the middle position of the roller conveyor line 1 through the centering device 4, and then the steel plate can be stopped under the heating device 3 at the required position through the transportation of the roller conveyor line 1 and the inspection of the infrared ranging sensor 7, and then the multiple groups of electromagnetic induction heating rings 302 installed on the heating device 3 can selectively work to control the heating area of ​​the steel plate, thereby achieving the effect of controlling the heating area according to the heating needs of the steel plate, and the lifting device 2 can bring the heating device 3 close to the steel plate to greatly reduce energy loss and thus reduce energy consumption, and the instant heating of the electromagnetic induction heating ring 302 under the heating device 3 can avoid additional energy loss when not heating, thereby reducing energy consumption.
