Description

Technical Field

[0001] The utility model relates to the technical field of strip steel coiling, in particular to a tension hydraulic compensation adjustment mechanism based on strip steel coiling. Background Art

[0002] At present, the competition in the steel market is becoming increasingly fierce, and new products and new processes of major steel mills are emerging in an endless stream; especially in the silicon steel market, new products with higher magnetism and lower iron loss have been launched in the market one after another, and each process of silicon steel coil production will inevitably involve tension coiling. Especially in the continuous trimming and rewinding unit for producing high-end silicon steel varieties, there are two main ways to adjust the coiling tension: one is the mechanical tension pressure plate and the method of filling the tension pad. This method relies solely on the manual adjustment of the operator, and the adjusted coiling tension can only be felt by hand. The coiling tension parameters cannot be clearly adjusted in this way, and there are serious safety hazards when feeling the running strip tension by hand; the second is to make some improvements on the basis of the first method, that is, an inflatable airbag and a current sensing device are added to the lower guide plate of the tension pressure plate. This method greatly improves the tension monitoring and adjustment of the strip coiling, but the inflatable airbag is easy to be scratched and leaked when the strip coiling deviates, and loses its function.

[0003] The utility model with publication number CN204135110U discloses a strip coiling tension compensation adjustment device, including an upper tension pressure plate and a lower tension pressure plate. The upper end surface of the upper tension pressure plate is connected to the output end of the manual adjustment mechanism, the lower end surface of the upper tension pressure plate is paved with an upper tension pad, and the upper end surface of the lower tension pressure plate is paved with a lower tension pad. The two ends of the lower tension pressure plate are respectively supported by the adjustment device. The adjustment device includes a hydraulic cylinder, a connecting rod mechanism, a support frame and a proportional control valve for controlling the output pressure of the hydraulic cylinder. The proportional control valve is also connected to the PLC logic programmer.

[0004] As shown in the above utility model, the existing tension hydraulic compensation adjustment mechanism can balance the pressure on both sides of the running strip through the manual adjustment mechanism, so that the upper tension pad can avoid deviation; and when the strip coiling tension is too small or too large, the proportional control valve is controlled to change the flow of the hydraulic cylinder in the adjustment device, thereby changing the degree of compression of the lower tension plate on the lower tension pad, so as to achieve the purpose of real-time supplement of the coilable tension, so as to avoid squeezing and collapse of the strip after coiling. On the one hand, this method requires the adjustment of the pressure on both sides of the steel strip through the manual adjustment mechanism, which is time-consuming and labor-intensive. On the other hand, the tension compensation is performed through the tension plate and the tension pad, and its deformation range is small, and it is not possible to adjust the tension compensation of the steel strip in a larger range as needed.

The guide roller 13 cooperates with the adjusting roller 15 to adjust the tension of the steel belt.

[0027] The clamping assembly 2 is located between the first two guide rollers 13, and is used to clamp and limit the steel strip on the steel strip roll 12. The clamping assembly 2 includes a telescopic cylinder 21 fixed to the middle of the upper end of the front side of the mounting plate 1, and the bottom end of the telescopic cylinder 21 is fitted with a baffle 22 fixed on the mounting plate 1.

A plurality of damping strips 25 distributed at equal intervals are bonded to the lower surface of the splint 24. The pressure plate 23 cooperates with the splint 24 to clamp and limit the steel strip. The setting of the damping strip 25 increases the friction force and improves the clamping effect.

[0028] The tension compensation component 3 is arranged on the other side of the back side of the mounting plate 1 , and the tension compensation component 3 is connected to the adjustment roller 15 , and is used for tension compensation adjustment of the steel strip on the steel strip roll 12 .

[0029] The second embodiment is mainly different from the first embodiment in that: the tension compensation component 3 includes a movable plate 31 arranged on the outer side of the back opening of the linear slot 14, the inner middle part of the movable plate 31 is fixedly connected to one end of the adjusting roller 15, and dovetail sliders 32 are fixed to both ends of the inner side of the movable plate 31.
