Description

Technical Field

[0001] The invention relates to the technical field of steel coil sampling, and in particular to a sampling device for steel coils with a thickness of ≥5mm. Background Art

[0002] In hot rolling production, steel coils with a thickness of generally less than 5mm can be cut and sampled using online sampling equipment. It is difficult to cut steel coils with a thickness of 5mm or more online. After the steel coils are offline, the stress increases due to the decrease in the temperature of the steel coils, making it difficult to unwind. At present, hot rolling mills use offline cutting sampling for steel coils with a thickness of 5mm or more. Offline sampling is done after manual unwinding. Due to the high stress of thick steel coils, it is difficult to unwind manually without special unwinding tools. Once too much force is applied, the steel coils will rebound, which is easy to cause harm to the human body and pose a safety hazard. At the same time, the sampling work is difficult, time-consuming, and requires more manpower. Generally, 2-3 people are required to cooperate to complete it. In addition, when manually prying open the steel coils for flame cutting sampling, the spacing 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 coil, causing damage to the surface quality of the steel coil. Summary of the invention

[0003] In response to the above-mentioned technical problems, the purpose of the present invention is to provide a sampling device for steel coils with a thickness of ≥5 mm, which can effectively reduce the labor intensity of sampling steel coils with a thickness of 5 mm and above, improve the safety during manual sampling, and better prevent the quality loss caused by cutting slag splashing into the inner surface of the steel coil.

[0004] The object of the present invention is achieved in this way: a sampling device for steel coils with a thickness of ≥5mm, comprising a fixed bracket, a hydraulic mechanism, a block, a roller, a bearing seat, a drive motor, and an electrical operating panel, wherein two rollers are arranged in parallel on the bearing seat, one of the rollers is provided with a drive motor, and is connected to the electrical operating panel through a wire, and is characterized in that slots are provided on the left and right columns on the fixed bracket, and the block is slidably connected to the slot; the hydraulic mechanism is vertically arranged under the block, and its piston rod head is connected to the block through a pin shaft.

[0005] The end of the stopper is wedge-shaped.

[0006] When the present invention is in use, the steel coil is placed on the roller, and the piston rod of the hydraulic mechanism is driven to rise, so that the blocks arranged in the slots of the left and right columns on the fixed bracket abut against the steel coil, and then the motor is operated to control the rotation of the roller to cause the tail of the steel coil to unfold to the left. Under the action of the block, a long section of the steel coil can be separated, which is convenient for manual cutting and sampling without damaging the inner surface of the steel coil.

[0007] Compared with the prior art, the present invention can effectively reduce the labor intensity of sampling steel coils with a thickness of ≥5mm, improve the safety of workers when taking samples, and better prevent quality loss caused by cutting slag spraying into the surface of the steel coil, and has a simple structure and is easy to manufacture.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Figure 1 , Figure 2 A sampling device for steel coils with a thickness of ≥5 mm, comprising a fixed support 4, a hydraulic mechanism 2, a stopper 3, a roller 5, a bearing seat 6, a drive motor 7, and an electrical operation panel 8. Two rollers 5 are arranged in parallel on the bearing seat 6, one of which is provided with a drive motor 7, and connected to the electrical operation panel 8 through a wire. The device is characterized in that a card slot 401 is arranged on the left and right columns of the fixed support 4, and the stopper 3 is slidably connected to the card slot 401; the hydraulic mechanism 2 is vertically arranged under the stopper 3, and its piston rod head is connected to the stopper 3 through a pin 9. The end of the stopper 3 is wedge-shaped.

[0012] Example: Figure 1 , Figure 2As shown, a group of two rollers 5 with the same size and specification are selected and arranged on the same horizontal plane. The two ends of the rollers 5 are placed in the bearing seat 6, and the bearing seat 6 is fixed to the support plate 10 with bolts. The end of one of the rollers 5 is connected to the drive motor 7 by bolts, and the control end of the drive motor 7 is connected to the electrical operation panel 8 through a transmission wire. The steel coil 1 is placed on two parallel rollers 5, and the left and right columns on the fixed bracket 4 are provided with a card slot 401. The card slot 401 on the fixed bracket 4 is a dovetail groove, which is interlocked with the dovetail convex head protruding from the side of the stopper 3, so that the stopper 3 is slidably connected with the card slot 401; the hydraulic mechanism 2 is placed vertically under the two stoppers 3, and the lower end of the hydraulic mechanism 2 is fixed to the support plate 10 by bolts. The upper end of the hydraulic mechanism 2 The piston rod head bayonet is provided with a through hole, and the pin 9 is used to connect with the stopper 3. The stopper 3 is set in a wedge shape, so that the wedge head is easier to insert into the tail of the steel coil 1 and expand outward. When the lower chamber of the hydraulic mechanism 2 on both sides is filled with oil, the block 3 is pushed up along the slot 401 on the fixed bracket 4 to resist the steel coil 1 placed on the roller 5. When the upper chamber of the hydraulic mechanism 2 is filled with oil, the block 3 is restored to the original position. The specific working process of the present invention is as follows: the steel coil 1 is placed on the roller 6, and the hydraulic mechanism 2 on both sides is driven to rise so that the block 3 on both sides moves upward along the slot 401 on the fixed bracket 4 to press the steel coil 1, and then the motor operating panel 8 controls the driving motor 7 to drive the roller 5 to rotate. When the tail of the steel coil 1 moves to the left, under the action of the block 3, the tail of the steel coil 1 is forced to move to the left to separate a long section of the steel coil 1, which is convenient for manual cutting and sampling.
