Abstract
A kind of metal plate cutting machine consists of electromotor, slowdown organization, transmission and working mechanism. Its characteristic is that the transmission and the workimg mechanism contain single-axes double-crank connecting level mechanism, air pressure cylinder balance mechanism, draw-pole mechanism which can make elastic running, top and bottom edge rest and edge. The strongpoint is that all the pole parts of the whole cutting machine accepts force with reason and steadily, prolongs the employ life of machine and enhances cutting quality of the plate. At the same time, in the cutting process, round arc's top edge makes approximate roll and cutting movement following parallel bottom's edge, then both of them keep the same quantity of superposition consistent following the slab width's direction.
Description
Technical field:
The invention belongs to metal sheet shearing machine tool technical field, be specifically related to a kind of single shaft double eccentric rolling cut type metal sheet shearing machine.
Background technology:
At present, the roll-turning cutter that is used to shear metallic plate both at home and abroad has polytype, and is two eccentric if any twin shaft, hydraulic driven etc.They respectively have shortcoming, the complex structure of twin shaft double eccentric-pieces, huge, hydraulicdriven needs one cover hydraulic test etc., and various types of cutters all exist in shear history each member stress and stablize, have fluctuation and oscillation phenomenon inadequately, are having a strong impact on the quality of service life of a machine and product.
Summary of the invention:
The rolling cut type metal sheet shearing machine that the purpose of this invention is to provide a kind of new construction can overcome the defective that prior art exists effectively.
The present invention is achieved in that as shown in Figure 1, 2 it is made up of motor 14, reducing gear 13 and transmission and operating mechanism.Described transmission and operating mechanism, it is characterized in that it comprises the single shaft drag link, the pneumatic cylinder balanced controls, can make the moving drag link mechanism of axial elasticity string, and go up the lower scissor blade knife rest and form, the angle of two crank throw point A on the two-throw crankshaft 9 and the axis projection of B is α=45 °-100 °, connecting rod 1, two crank throw point A on 2 its upper ends and the two-throw crankshaft 9, B is hinged by sphere, the lower end is by the C on spherical hinge and the upper scissor blade knife rest 10, the D point connects, pneumatic cylinder 8 (four) upper end is connected with frame by hinged, lower end piston rod 3,4,5,6 by the G on hinged and the upper scissor blade knife rest 10, H, G ' H ' connects, (G ', the position of H ' on the back side of upper scissor blade knife rest 10 with G, H is symmetrical), can make the moving pull bar 7 of axial elasticity string, the one end is connected with E point on the frame by hinge, and the other end is connected with F point on the upper scissor blade knife rest 10 by hinge.
Learn through experimental study, the present invention starts each mechanism of back and moves, two-throw crankshaft 9 rotates, drivening rod 1,2 motions, when the axis projection angle α of two crank throw point A on the two-throw crankshaft 9 and B=45 °-100 °, under the effect of contraction of pull bar 7, can make circular arc cutting edge on the upper scissor blade knife rest 10 in shear history, can do approximate rolling cut and move along parallel lower scissor blade, two cutting edges are up and down remained unchanged along the lap of the last lower scissor blade on the sheet material width.Pneumatic cylinder 8 can play the effect of balance upper scissor blade knife rest 10 weight in shear history, and can eliminate the gap that connecting rod and crank, connecting rod and upper scissor blade knife rest sphere are hinged, reduce the vibration and the impact of each rod member, axial resilient pull bar 7, in shear history, a spot of axial motion can be done, stability and accuracy in the shear history can be guaranteed.
Advantage of the present invention and good effect:
1. but the present invention has adopted the pull bar stabilizing mechanism of single shaft double eccentric toggle and pneumatic cylinder balanced controls and flexible axial motion, make each rod member of whole cutter stressed rationally, stable, and can eliminate the gap of each rod member junction, fluctuation and vibration have been reduced to be subjected to, prolong machine service life, improved the metallic plate shearing quality.
2. adopted two-throw crankshaft axis projection angle α=45 °-100 °, and can make the moving drag link mechanism of axial elasticity string, make in the shear history circular arc upper scissor blade do approximate rolling cut and move, the lap of the last lower scissor blade on the sheet material width of two cutting edges is up and down remained unchanged along parallel lower scissor blade.
