Description
Technical Field
The invention relates to the technical field of steel strip slitting equipment, in particular to a self-adaptive steel strip clamping device.
Background
The steel strip slitting machine is a device for cutting a mother steel strip with a large width into a plurality of sub steel strips with a required width along a rolling direction. Since the mother steel strip is produced by rolling in a steel mill, the width of the steel strip and the straightness of the edge of the steel strip have obvious deviation, and particularly, the positions of the head and the tail of the steel strip at 10 meters have drastic changes. In order to obtain the child steel belt with high width and straightness accuracy, one side edge of the parent steel belt needs to be fixed, so that the cutting position of the fixed side disc shear blade is kept unchanged. This requires that the strip always remain in a one-sided position, the other side is preloaded with a pre-load to clamp, and the width and alignment of the parent strip is accommodated.
Disclosure of Invention
The invention provides a self-adaptive strip steel clamping device for solving the problems, which keeps the single-side position stable under the state that the width and the straightness of the mother strip steel are continuously changed.
The above object of the present invention is achieved by the following technical solutions: the self-adaptive strip steel clamping device comprises a base, and a fixed clamping mechanism and a movable clamping mechanism which are arranged at the left end and the right end of the base, wherein the fixed clamping mechanism comprises a fixed guide wheel which is fixedly arranged on the base; the movable clamping mechanism comprises a movable seat, a sliding rail and a movable guide wheel, the sliding rail is fixed on the base, the movable seat is slidably arranged on the sliding rail, and the movable guide wheel is rotatably arranged on the movable seat and moves in the left-right direction relative to the fixed guide wheel; a hydraulic assembly is arranged between the base and the movable base, the hydraulic assembly is connected with a control oil circuit, the control oil circuit comprises a driving oil circuit and a protection oil circuit, and the driving oil circuit and the protection oil circuit are connected in parallel; the driving oil way is used for pushing the movable guide wheel to move towards the direction close to the fixed guide wheel so that the movable guide wheel is tightly close to the side edge of the strip steel, and the protection oil way is used for unloading the pressure of the hydraulic assembly when the width of the strip steel is increased and pushing the movable guide wheel to move towards the direction far away from the fixed guide wheel by the strip steel.
The traditional spring adjusting mechanism has the obvious defect that the elasticity of the spring changes along with the change of the length, so that the elasticity of the spring is small when the spring is extended, the pressure of the guide wheel acting on the strip steel is small, and the strip steel cannot be effectively clamped; when the spring is shortened, the elasticity of the spring is large, the pressure of the guide wheel acting on the strip steel is large, the strip steel is easy to squeeze and deform, and therefore the transmission spring adjusting mechanism cannot use the condition that the width of the strip steel is greatly changed; when the width of the strip steel is reduced, the movable clamping mechanism provided by the invention drives the oil way to push the movable seat to move, so that the movable guide wheel approaches the fixed guide wheel, the movable guide wheel and the fixed guide wheel are ensured to be clamped on two sides of the strip steel all the time, and the pressure of the guide wheel acting on the strip steel can be controlled through the oil way; when the width of the strip steel is increased, the pressure of the hydraulic component is unloaded by the protection oil way, so that the movable guide wheel can move away from the fixed guide wheel under the pushing of the strip steel, the distance between the movable guide wheel and the fixed guide wheel is passively regulated, and the movable guide wheel and the strip steel keep proper pressure, thereby adapting to the change of the width and the side linearity of the strip steel, and avoiding the situation that the strip steel cannot be effectively clamped when the width of the strip steel is reduced, or the clamped strip steel is arched and deformed when the width of the strip steel is increased and the distance between the guide wheels is unchanged.

The set pressure of the pressure reducing valve and the back pressure valve is set according to the material, the width and the thickness of the strip steel, so that the situation that the strip steel is arched due to the fact that the set pressure of the back pressure valve cannot be backed down when the pressure of the guide wheel applied to the strip steel is smaller than the set pressure of the back pressure valve when the width of the strip steel is increased is avoided.
Preferably, the flow direction of the driving oil passage is from the hydraulic chamber on the front side of the piston to the hydraulic chamber on the rear side of the piston, and the flow direction of the protection oil passage is from the hydraulic chamber on the rear side of the piston to the hydraulic chamber on the front side of the piston.
