Description

Technical field

[0001] The utility model belongs to the technical field of cold shearing of bar materials, and in particular relates to a cold shearing system for improving the cold shearing efficiency of bar materials. [Background Technology]

[0002] Cold shears are key equipment in bar production lines. They are mainly used for cutting bars to a fixed length. They are the last shearing process on the production line. The reliability of the shears has a great impact on the output of the entire production line and the appearance quality of the products.

[0003] Currently, when cold shearing steel tails, the pressure plate moves every time the cold shear performs a shearing action. If there is no steel under the pressure plate, the pressure plate performs useless work. The disadvantages are as follows: ① It wastes air supply; ② It shortens the life of equipment such as solenoid valves, pressure rollers, mechanical connections, and cylinders; ③ The pressure of the pressure plate affects the shearing efficiency, which in turn affects the production rhythm of the rolling line. [Utility Model Content]

[0004] The utility model aims to provide a cold shear system for improving the shearing efficiency of bar cold shears, so as to solve the problem that when the existing cold shears are shearing finished bars, the pressing plate also moves when there is no steel under the pressing plate, resulting in waste.

[0005] The utility model adopts the following technical solutions: a cold shearing system for improving the cold shearing efficiency of bar materials, comprising a horizontally arranged roller conveyor, a cold shearing machine arranged on the roller conveyor, a shearing blade of the cold shearing machine located at the center of the cold shearing machine, and a shearing line formed by the shearing action of the shearing blade being perpendicular to the moving direction of the bar material; a pressing plate is arranged on the cold shearing machine on the side close to the incoming material direction, and a baffle is arranged on the side of the cold shearing machine on the outgoing material direction; an area sensor and a pressing plate action judgment module are arranged on the pressing plate;

[0006] Among them, the roller is used to transport the bars; the baffle is used to move up and down vertically along the roller, and is also used to block the movement of the bars after it descends; the pressure plate action judgment module is used to receive the sensing results of the area sensor on whether there are bars, and if there are bars, it outputs the action instruction for the pressure plate to press down, and if there are no bars, it outputs the action instruction for the pressure plate not to press down; the pressure plate is used to receive the instructions output by the pressure plate action judgment module and perform corresponding actions; the cold shear is used to shear the bars after the pressure plate performs the corresponding action according to the received instructions.

[0007] Furthermore, a transmitter and a receiver are respectively provided at the pressure plate and on both sides of the roller.

[0008] Furthermore, the number of the rods is one or more.

[0009] Furthermore, a plurality of rollers are vertically and spaced apart on the roller conveyor.

[0010] The beneficial effects of the present invention are as follows: by providing an area sensor on the lower roller of the cold shear platen, the cold shear is able to prevent the platen from moving when it detects that there is no steel under the platen, and to operate normally when it detects that there is steel under the platen, effectively improving the shearing efficiency of the cold shear, reducing energy consumption, and extending the life of the platen system. At the same time, it can also save gas and reduce electricity consumption per ton of steel; extend the life of equipment such as the solenoid valve, rollers, mechanical connection parts, and cylinders; and reduce the labor intensity of maintenance personnel; improve the shearing efficiency of the cold shear, thereby accelerating the production rhythm of the rolling line and increasing output.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] The utility model provides a cold shearing system for improving the cold shearing efficiency of bar materials, such as Figure 1 As shown, it includes a horizontally arranged roller 6, on which a cold shear 1 is arranged. The shear blade of the cold shear 1 is located at the center of the cold shear 1, and the shear line 2 formed by the shearing action of the shear blade is perpendicular to the movement direction of the bar 8; a pressing plate 3 is provided on the cold shear 1 near the incoming material direction, and a baffle 4 is provided on the outgoing material direction side of the cold shear 1; an area sensor 5 and a pressing plate action judgment module are provided on the pressing plate 3.

[0017] Among them, the roller 6 is used to transport the rod 8; the baffle 4 is used to move up and down perpendicular to the roller 6, and is also used to block the movement of the rod 8 after descending; the pressure plate action judgment module is used to receive the sensing result of the area sensor 5 on whether the rod 8 exists, and if the rod 8 exists, it outputs the action instruction of the pressure plate pressing down, and if the rod 8 does not exist, it outputs the action instruction of the pressure plate not pressing down; the pressure plate 3 is used to receive the instruction output by the pressure plate action judgment module and perform the corresponding action; the cold shearing machine 1 is used to shear the rod 8 after the pressure plate 3 performs the corresponding action according to the received instruction, that is, completes a cold shearing action.

[0018] like Figure 2 As shown, the bar material that has moved to the baffle 4 is stopped by it. The cold shear 1 then sends a command to the press plate, which is sensed by the area sensor 5. The press plate action determination module then determines whether there is a bar material under the press plate. If there is a bar material 8, the press plate is instructed to press down. If not, the press plate is instructed not to press down. The press plate then executes the corresponding command based on the detection result, and then the cold shear 1 performs the cutting.

[0019] After the shearing is completed, the baffle 4 rises and the bar continues to move; then the baffle 4 is lowered to block the steel head of the bar 8 that is subsequently transported; then the pressing plate action judgment module continues to detect whether there is a bar under the pressing plate, and the pressing plate executes the corresponding instructions according to the detection situation; then the cold shear 1 is used for cutting. This cycle continues until the entire bar is sheared. Figure 3 As shown in the figure, when cutting to the last section of bar, there is usually no bar under the pressing plate 3. According to the sensing signal of the area sensor 5, it can be known that the pressing plate does not need to perform the downward pressing action. Then the cold shearing machine 1 is used for cutting, that is, the cold shearing action of the last section is completed.

[0020] In some embodiments, a transmitter 51 and a receiver 52 are provided at the pressing plate 3 and on both sides of the roller conveyor 6. The transmitter 51 sends a signal. If the receiver 52 receives the signal, it means that there is no bar 8 at the pressing plate and the pressing plate does not need to be pressed down. If the receiver 52 does not receive the signal, it means that there is a bar 8 at the pressing plate and the pressing plate 3 can be pressed down.

[0021] The utility model installs infrared light emitters 51 and receivers 52 of area sensors on both sides of the roller below the pressing plate respectively. After being received, amplified and filtered by the photosensitive tube, a switching signal is output, and the signal is input into the PLC400 program to participate in the control of the cold shear system. When the cold shear is shearing the finished bar, if the area sensor detects that there is no steel, the pressing plate will not move. When the area sensor detects that there is steel, the pressing plate will move normally.

[0022] In some embodiments, the bar 8 is one or more bars. If multiple bars 8 are used, the bars 8 can be bundled together and sheared.

[0023] In some embodiments, a plurality of rollers 7 are vertically and spaced apart on the roller conveyor 6 to transport the rods 8 .

[0024] By installing an area sensor on the lower roller of the cold shear platen, the utility model realizes that when the cold shear is shearing finished bars, if it detects that there is no steel under the platen, the platen will not move. If it detects that there is steel under the platen, the platen will move normally, effectively improving the shearing efficiency of the cold shear, reducing energy consumption, and extending the life of the platen system equipment. At the same time, it can save gas and reduce electricity consumption per ton of steel; extend the life of equipment such as solenoid valves, rollers, mechanical connections, and cylinders, while reducing the labor intensity of maintenance personnel; improve the shearing efficiency of the cold shear, thereby accelerating the production rhythm of the rolling line and increasing output.
