Abstract
An adjusting device for clearance between an upper shearing edge and a lower shearing edge of a hydraulic rolling shear belongs to the technical field of rolling shears, which comprises an integral framework, an upper shearing edge tool rest, fixed tapered wedges, moving tapered wedges, pull rods and a pull rod controlling device. The adjusting device for clearance between an upper shearing edge and a lower shearing edge of a hydraulic rolling shear is characterized in that the fixed tapered wedges and the moving tapered wedges are respectively mounted among four corners, a left upright post and a right upright post of the integral framework and the upper shearing edge tool rest, and the moving tapered wedges are connected with a lead screw of a worm speed reducer through the pull rods with fine adjustment functions. The pull rod controlling device is composed of an electric motor and a speed reducing reversing mechanism capable of enabling the left pull rod and the right pull rod to move reversely. When the left moving tapered wedge move upwardly, the right moving tapered wedge moves downwardly to push the upper shearing edge tool rest to move left, thereby increasing the clearance between the upper shearing edge and the lower shearing edge, on the contrary, when the left moving tapered wedge moves downwardly, the right moving tapered wedges move upwardly to push the upper shearing edge tool rest to move right, thereby reducing the clearance between the upper shearing edge and the lower shearing edge. During the adjusting process, a holding apparatus fixed on the right upright post always gives a certain push force to the upper shearing edge tool rest, thereby guaranteeing zero-clearance adjustment between the upper shearing edge and the lower shearing edge.
Description
Technical field
The utility model belongs to rolling cut and cuts technical field, is specifically related to a kind of adjusting device of blade clearance up and down of hydraulic pressure rolling cut shearing machine.
Background technology
At present, the adjusting device of blade clearance up and down of hydraulic pressure rolling cut shearing machine all realizes having manual, motor-driven and the hydraulic operation mode by mobile lower scissor blade both at home and abroad.Its shortcoming is because lower scissor blade is in the comparison harsh environmental conditions in shear history, there are many iron scales and waste residue in shear history, to drop in the crack of regulating between wedge and the cutter box, cause the blade clearance value to be far smaller than rational glade plane space like this, cause in the shear history, mobile space is little, adjusting position is inaccurate, the blade clearance value changes, directly influence band steel shearing quality.
Summary of the invention
The utility model purpose provides a kind of adjusting device of blade clearance up and down of new hydraulic pressure rolling cut shearing machine, can overcome the shortcoming that prior art exists effectively.
The utility model is achieved like this, it comprises the whole frame that is made of four root posts of left and right sides frame and entablature, the upper scissor blade knife rest, fixing wedge, mobile wedge, pull bar and control operating rod device, it is characterized in that four bights in whole frame, be separately installed with between left and right pillar and the upper scissor blade knife rest by four fixing wedge adjusting devices of forming of wedge and four corresponding cooperations of mobile wedge, four fixedly wedge be separately fixed on the column corresponding with it, four mobile wedge upper ends pull bar by playing the fine setting effect be installed in entablature on the screw mandrel of worm reduction gear in four bights be connected.Described control operating rod device is can make left and right sides pull bar make heterodromous deceleration changement by a motor drives one cover that is installed on the entablature, promptly when moving left wedge when moving upward, the wedge that moves right moves downward, promote upper scissor blade knife rest and upper knife edge and move to left, the blade clearance increases up and down, otherwise, on the contrary. in this adjustment process, be fixed on three groups of hold down gags on the right column, give the certain thrust of upper scissor blade knife rest all the time, guarantee the zero-clearance adjustment of blade clearance up and down.
The utility model advantage and good effect thereof are (1) owing to be to adopt the control method that changes upper scissor blade knife rest position, can improve the shearing work condition greatly, and shearing quality is improved; (2) adopt the Wedge mechanism adjusting device, sliding contact surface is bigger, and contact is closely slided steadily, realizes easily accurately adjusting; (3) easy to operate, easily be automated.
