Technical field
The present invention relates to a kind of plate shearing machine numerical control drive unit, relating in particular to driving mechanism is crank-connecting rod-toggle link plate shearing machine numerical control drive unit.
Background technology
Plate shearing machine be according to dimensional requirement to the shearing equipment that sheet material cuts off processing, be that the most popular material of each industrial department is cut off equipment, be mainly used in the linear edge of cutting out the various sizes sheet metal, have extensive use in the manufacturing field.CNC shearing machine is meant with the digital command of numeral, literal and symbol composition commands driving mechanism to realize the technology of a plate shearing machine or many plate shearing machine device motion controls.
At present, the type of drive of plate shearing machine main motion mainly contains hydraulic pressure, pneumatic and mechanical three kinds.Wherein, the technical problem underlying of hydraulic plate shears existence is: 1, fluid is revealed and is caused environmental pollution; 2, transmission efficiency is low, causes bigger energy waste; 3, Hydraulic Elements such as pump, valve price is expensive, safeguards difficulty; 4, the large hydraulic plate shearing machine needs hydraulic pump to have bigger flow, also needs fuel tank to have bigger volume simultaneously, causes systems bulky.The technical problem underlying that airoperated clipper exists is: 1, system pressure is low, can only be used for the less occasion of shearing force; 2, gas has compressibility, can't as hydraulic plate shears, adopt synchronization loop, thereby can not be used for the bigger occasion of shearing width.The technical problem underlying that the traditional mechanical plate shearing machine exists is: 1, automatic control level is low; 2, must adopt guide rail that the movable knife rack rectilinear motion is led, certainly will cause the excessive complex structure manufacturing of guide rail width, increase manufacture difficulty, improve manufacturing cost, and can't guarantee shear precision for large-scale plate shearing machine.
Summary of the invention
The purpose of this invention is to provide crank-connecting rod-toggle link plate shearing machine numerical control drive unit; With shearing force, the automatic control level that improves mechanical plate shearing machine, omit the motor-driven knife rest guiding rail of mechanical shear simultaneously, simplified structure; Improve plate shearing machine shearing width and precision, improve its operating efficiency.
For achieving the above object; The technical scheme that the present invention adopts is: crank-connecting rod-toggle link plate shearing machine numerical control drive unit; The top shoe and the movable knife rack that comprise the transmission mechanism of digital control system, motor, the said motor of connection, the force-increasing mechanism that connects said transmission mechanism, the said force-increasing mechanism of connection; Said transmission mechanism comprises that toggle, said force-increasing mechanism comprise elbow-bar mechanism, and said slide block is arranged in the chute, and said slide block is fixedly installed on the said movable knife rack; Said elbow-bar mechanism one end connects the fuselage other end and connects said slide block; The crank of said toggle connects the rotor of said motor, and the connecting rod of said toggle connects the middle part of said elbow-bar mechanism.
Preferably, said force-increasing mechanism is that elbow-bar mechanism comprises first toggle link, second toggle link, and said first toggle link, one end connects the fuselage other end and connects said second toggle link, and the said second toggle link other end connects said slide block.
Preferably, said toggle comprises said crank, said connecting rod, and the rotor other end that said crank one end connects said motor connects said connecting rod, and the said connecting rod other end connects said first toggle link, the second toggle link junction.
Preferably, said motor and said transmission mechanism, force-increasing mechanism are symmetrically arranged with two groups, and said digital control system is controlled the synchronous rotation of said motor.
In the such scheme, said digital control system is the interlocked numerical controlled system of twin shaft, can send electronic signal to two motors synchronously; Said motor is a servomotor, utilizes two groups of transmission mechanisms about the servomotor driven in synchronism, and the pressure angle of two toggle links is identical about can guaranteeing like this; Just can guarantee synchronism, wherein rotating speed of motor is not permanent rotating speed, and its speed is wanted corresponding reducing in the time of in getting into impulse stroke; When getting into backhaul, with bigger acceleration backhaul.
Operation principle of the present invention is: at first; Digital control system is sent instruction; Two servomotors rotate with speed simultaneously; Driving crank and connecting rod movement; Pressure angle
diminishes, and carries out the power amplification first time.Simultaneously; First toggle link and second toggle link receive the thrust of connecting rod; Pressure angle
also diminishes; Carry out power amplification second time this moment, and transmission mechanism drives movable knife rack to the down cut workpiece by slide block after carrying out twice power amplification.After shearing finished piece(s), digital control system is sent instruction to motor, drives toggle and reverses simultaneously, and pulling elbow-bar mechanism return goes up movable knife rack by the slide block drive simultaneously and resets, and accomplishes a course of work.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention has used digital control system, servomotor and crank-connecting rod-toggle link force-increasing mechanism, can not only make transmission mechanism synchronous accurately, and power output also amplifies manyfold, can accomplish shearing work, high efficiency preferably.
2, because driver of the present invention constitutes the axial symmetry distribution, make movable knife rack stressed evenly, shear precision is high.
3, because the 2-axis linkage crank method for synchronous that the present invention adopts simplifies the structure, guaranteed simultaneously to drive synchronously about movable knife rack.Not only can omit traditional plate shearing machine movable knife rack guiding rail, and can improve shearing width and precision greatly, improve its operating efficiency.
