Description

A sampling device for steel coils with a thickness ≥ 5mm

technical field

The invention relates to the technical field of steel coil sampling, in particular to a sampling device for steel coils with a thickness ≥ 5 mm.

Background technique

In hot continuous rolling production, generally steel coils with a thickness of less than 5mm can be sheared and sampled by online sampling equipment. Steel coils with a thickness of 5mm and above are difficult to shear online. It is difficult to open the book. At present, hot continuous rolling mills adopt off-line cutting and sampling for steel coils with a thickness of 5mm and above. Off-line sampling is performed after manual uncoiling. Due to the high stress of thick-gauge steel coils, it is difficult to uncoil manually without special uncoiling tools. , It is difficult to complete the sampling work, it takes a long time, and it requires more manpower. Generally, 2-3 people are required to cooperate to complete it. In addition, when the steel coils are manually pried open for flame cutting and sampling, the distance between the steel coils is small. Therefore, during the flame cutting operation, the cutting slag is easy to splash into the inner surface of the steel coils, resulting in damage to the surface quality of the steel coils.

Contents of the invention

In view of the above-mentioned technical problems, the purpose of the present invention is to provide a sampling device for steel coils with a thickness ≥ 5 mm, which can effectively reduce the labor intensity of sampling steel coils with a thickness of 5 mm and above, improve the safety of manual sampling, and at the same time be more It is good to prevent the quality loss caused by the cutting slag splashing into the inner surface of the steel coil.

The object of the present invention is achieved like this: a kind of sampling device of thickness ≥ 5mm steel coil, comprises fixed support, hydraulic mechanism, stop block, idler roller, bearing seat, driving motor, electric operation panel, two idler rollers are arranged in parallel On the bearing seat, one of the rollers is provided with a driving motor, which is connected to the electric operation panel through a wire. It is vertically arranged under the block, and its piston rod head is connected with the block through a pin shaft.

The end of the stopper is wedge-shaped.

When the present invention is in use, the steel coil is placed on the supporting roller, and the piston rod of the hydraulic mechanism is driven to rise, so that the stoppers provided in the slots on the left and right sides of the fixed bracket are against the steel coil, and then the motor is operated to control the rotation of the supporting roller. Prompt the tail of the steel coil to unfold to the left, under the action of the stopper, a long section of steel coil can be separated, which is convenient for manual cutting and sampling without damaging the inner surface of the steel coil.

Compared with the prior art, the present invention can effectively reduce the labor intensity of sampling steel coils with a thickness of ≥5 mm, improve the safety of workers when sampling, and at the same time better prevent quality loss caused by spraying cutting slag into the surface of steel coils, Moreover, the structure is simple and the manufacture is easy.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and examples. Referring to Fig. 1 and Fig. 2, a sampling device for a steel coil with a thickness ≥ 5 mm includes a fixed bracket 4, a hydraulic mechanism 2, a stopper 3, an idler roller 5, and a bearing seat 6. The driving motor 7 and the electric operation panel 8, two supporting rollers 5 are arranged in parallel on the bearing housing 6, and one of the supporting rollers 5 is provided with a driving motor 7, which is connected to the electric operating panel 8 through wires, and is characterized in that, On the fixed support 4, the uprights on the left and right sides are provided with slots 401, and the block 3 is slidingly connected with the slots 401; The end of the stopper 3 is wedge-shaped.

Embodiment: As shown in Figure 1 and Figure 2, select a group of two idler rollers 5 with the same size and specification to be arranged on the same horizontal plane, place the two ends of the idler rollers 5 in the bearing housing 6, and the bearing housing 6 is fixed with bolts on the support plate 10. The end of one of the supporting rollers 5 is connected to the drive motor 7 by bolts, and the control end of the drive motor 7 is connected to the electric operation panel 8 through a transmission wire. The steel coil 1 is placed on two idler rollers 5 arranged in parallel, and the uprights on the left and right sides of the fixed bracket 4 are provided with slots 401. The protruding dovetail-shaped convex heads are interlocked so that the block 3 is slidingly connected with the slot 401; the hydraulic mechanism 2 is vertically placed under the two blocks 3, and the lower end of the hydraulic mechanism 2 is fixed to the support plate 10 by bolts. The bayonet of the piston rod head at the upper end is provided with a through hole, which is connected with the stopper 3 by a pin shaft 9 . The stopper 3 is arranged in a wedge shape, so that the wedge-shaped head is easier to insert into the tail of the steel coil 1 and expand outward. When oil is fed into the lower cavity of the hydraulic mechanism 2 on both sides, the stopper 3 is pushed up along the slot 401 on the fixed bracket 4 to resist the steel coil 1 placed on the supporting roller 5. When the oil is fed into the upper cavity of the hydraulic mechanism 2 Return stopper 3 to its original position. The specific working process of the present invention: put the steel coil 1 on the supporting roller 6, drive the hydraulic mechanism 2 on both sides to rise so that the stoppers 3 on both sides move upward along the slot 401 on the fixed bracket 4 to compress the steel coil 1, Then the driving motor 7 is controlled by the motor operation panel 8 to drive the supporting roller 5 to rotate. When the tail of the steel coil 1 moves to the left, under the action of the stopper 3, the tail of the steel coil 1 is moved to the left to separate a long section of the steel coil 1. It is convenient for manual cutting and sampling.
