Description
Technical field
The utility model belongs to the shearing equipment of the Runout area in the rolled plate production line, particularly shears the blade clearance adjusting device of a kind of rotary cutting length shear that slab uses.
Background technology
As everyone knows, rotary cutting length shear is the important shearing equipment of the Runout area in the rolled plate production line, comes the steel plate after cutting edge is carried out crop, back-end crop and cutting to length with it; Its structure comprises support, electric device, screw-threaded shaft elevator, leading screw, connecting rod, adjust wedge and fix the adjustment wedge that the adjustment wedge is formed by moving, upper tool post, upper scissor blade, lower slide and lower scissor blade and spring assembly, support top installing by electric device drive arranged evenly, the a plurality of screw-threaded shaft elevators that are synchronized with the movement, between the screw-threaded shaft elevator that adjoins, all connect with shaft coupling, side installing is by moving the adjustment wedge and fixing and adjust the adjustment wedge that wedge is formed in support, leading screw in each screw-threaded shaft elevator connects connecting rod separately, this connecting rod is connected with separately mobile adjustment wedge, the fixing side of adjusting wedge contacts with the upper tool post side of moving, opposite side in support distributes and installs spring assembly, its spring assembly can contact with the self-lubricating plate of upper tool post all the time along pressing plate, guarantees the zero-clearance guiding of upper tool post; Because each adjustment wedge matches with a side of the upper tool post that moves and touches, the bottom, another side of upper tool post is fixed with upper scissor blade, and is corresponding with the position of upper scissor blade, on fixing lower slide lower scissor blade is housed; Move the motion of adjusting the upper and lower both direction of wedge when the elevating screw machine drives by connecting rod, the fixedly adjustment wedge that is directed in the upper tool post produces horizontal displacement, and it is mobile to force upper tool post to produce in the horizontal direction, reaches the purpose of adjusting blade clearance.Because the size and the sheet metal thickness of the blade clearance of rotary cutting length shear are linear, therefore, before shearing, must adjust upper and lower blade clearance for the steel plate of different-thickness and material.If the blade clearance adjustment is inaccurate in shear history, will exerts an influence to quality of steel plates, and then influence the selling price and the market sales volume of steel plate.At present, the blade clearance adjusting device of rotary cutting length shear is by the encoder feedback backlash values, encoder is arranged in screw-threaded shaft elevator worm shaft end, need to eliminate the gap width between intermediate link screw-threaded shaft elevator worm gear and worm screw, leading screw and nut, the encoder usefulness reducer gear, regulate the speed slow, accuracy is low, the adjustment time is long.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, simple and practical, both be easy to assembling manufacturing, realize adjusting quick, accurate again, and it is good to have a shearing quality, the blade clearance adjusting device of a kind of rotary cutting length shear that production efficiency is high and easy to operate.
The purpose of this utility model is to adopt following technical scheme to realize: the blade clearance adjusting device of described rotary cutting length shear, comprise support, electric device, screw-threaded shaft elevator, leading screw, connecting rod, move and adjust wedge, the fixing wedge of adjusting, spring assembly, upper tool post, upper scissor blade, lower slide and lower scissor blade, it is characterized in that: at the top of any one screw-threaded shaft elevator installing displacement transducer, described displacement transducer is by sensor bar, magnet ring and not the magnetic conduction supporting plate form, the longitudinal centre line of leading screw in the longitudinal centre line of sensor bar and the screw-threaded shaft elevator is coincided, the top of sensor bar is connected on the casing of screw-threaded shaft elevator, in the upper rod section of screw mandrel, be provided with macropore that holds magnet ring and the deep hole that holds the sensor bar lower rod section in regular turn, magnet ring is packed in the macropore, the lower rod section of sensor bar is passed in the magnet ring insertion deep hole, between magnet ring bottom surface and macropore face, be equipped with not magnetic conduction supporting plate.
Principle of the present utility model and operation division are as follows: the utility model mainly is by moving the adjustment of the upper and lower motion realization blade clearance size of adjusting wedge, when mobile adjustment wedge moves downward, sideshake diminishes between upper scissor blade and the lower scissor blade, otherwise sideshake becomes big between upper scissor blade and the lower scissor blade.When blade clearance need be adjusted, electric device drives a plurality of elevating screw machines that are synchronized with the movement, link to each other with shaft coupling between each screw-threaded shaft elevator, the elevating screw machine again by from connecting rod with move the adjustment wedge separately and be connected, thereby drive to move and adjust the wedge motion of both direction up and down, adjust wedge and fixedly wedge generation relative displacement owing to move, it is mobile that upper tool post is produced in the horizontal direction, the upper scissor blade that drive puts together on the upper tool post moves, because lower scissor blade puts together on the lower slide and maintains static, thereby reach the purpose of adjusting upper and lower blade clearance.Be in course of adjustment, the pressing plate on the spring assembly contacts with the self-lubricating plate of upper tool post one side all the time, guarantees the zero-clearance guiding of upper tool post.Therefore in the utility model, adopted displacement transducer adjustment; It is the top that the sensor bar of the displacement transducer of MTS is arranged in the screw-threaded shaft elevator casing that its displacement transducer normally adopts model, stretches in the screw mandrel of screw-threaded shaft elevator, maintains static; The magnet ring of MTS displacement transducer is fixed on the leading screw inside of screw-threaded shaft elevator, moves with leading screw; The displacement of leading screw is to move the displacement of adjusting wedge, and the magnet ring of MTS displacement transducer moves with leading screw, produce relative displacement with MTS displacement transducer sensor bar, so, the relative shift that sensor bar fed back by the MTS displacement transducer is to move the displacement of adjusting wedge, multiply by the tangent value of adjusting the wedge oblique angle with displacement again, can draw the amount of movement of upper scissor blade, thereby draw the backlash values between the cutting edge.
Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, and is simple and practical, both has been easy to assembling and made, realize again adjusting fast, accurately, and it is good to have a shearing quality, production efficiency high and easy to operate etc. advantage.
