Description

The synchronous flying shearing machine of double crankshaft slide rail on the flying shear line

Technical field

The present invention relates to a kind of shearing equipment of sheet metal machining aggregate machinery, relate in particular to a kind of servo-actuated shearing equipment.

Background technology

On the sheet metal blanking processing line, need in the plate running, realize shearing processing to plate, in Chinese steel market use is the single axle technology of Japan Patent mostly, single axle technology drives little car body by a line shaft, line shaft is a bent axle, one end of bent axle passes through slide block, slide block and lower slide are fixed together, upper tool post and little car body are fixed together, slide block (lower slide) can on the tool-post structure guide pass, be decomposed into X to Y to slip, X to motion be exactly flying shearing machine (on, lower slide) chase after plate motion and returning movement to what send the plate direction, Y to motion be exactly the relative motion of flying shearing machine lower slide and upper tool post, thereby the realization shearing motion.Because lower slide is contained in the little car body by slide block, slide block+lower slide+little car body+upper tool post is owing to structure needs volume and weight bigger, movement inertia is bigger, especially X to high speed when back and forth turning to when moving back and forth moving component bigger to the impulse ratio of quiet upper spider, cause easily that scale is inaccurate, the excessive wear of environmental noise and moving parts.Because the slide block movement pair is sliding friction, coefficient of friction is bigger, long-term high-speed motion easily causes way rub, thereby produce guide clearance and become big, guide clearance is the gap blade between the lower slide on the plate shearing machine just, the increase in edge of a knife gap can cause the increase of shear burr, has influenced end product quality.Because moving component inertia is to bigger, under the identical situation of shear parameters, the power of motor of flying shearing machine is relatively large, and the flying shearing machine motor is high-power servomotor, and the increase of power of motor is very big to the increase of machine cost.Gap blade is adjusted manual mode, handwheel, worm gear case, feed screw nut's driving-chain are fixed on the little car body, screw mandrel one end and upper tool post connect, unclamp the connection screw of upper tool post and little car body during adjustment, thereby rotating handwheel drive upper tool post moves, realize gap adjustment function, must lock the connection screw of upper tool post and little car body after mixing up, operation is longer non-cutting time.

Summary of the invention

The invention provides a kind of use transmission mechanism connection and support knife rest, the synchronous flying shearing machine of double crankshaft slide rail in the motion of realization plate on a kind of little inertia flying shear line of on-line shearing.

The synchronous flying shearing machine of double crankshaft slide rail on the flying shear line of the present invention, comprise body and power set, on body two heel posts, establish upper and lower two bent axles respectively, bent axle coaxial line on two, twice bent axle coaxial lines, establish the gear pair of pair of meshing between upper and lower two bent axles, the elbow section of bent axle is connected with the side opening of upper tool post on two, the elbow section of twice bent axles is connected with the side opening of lower slide, the axis of two elbow sections of upper and lower two bent axles is arranged on the same vertical plane, vertical fixing one slide rail on the lower slide, upper tool post is provided with a slide block, and this slide block is connected with slide rail.

The gear physical dimension and the gear teeth digital-to-analogue of the gear pair of described pair of meshing are counted unanimity.

Fix a riser on lower slide, slide rail is vertically fixed on this riser.

The gear that key connects on the described upper and lower eccentric shaft is the clearance elimination gear group.

Upper and lower knife rest of the present invention is connected on two bent axles, and the slide block on the upper tool post moves in the fixing slide rail on lower slide, has limited the free degree of upper and lower knife rest by transmission mechanism, makes upper and lower knife rest do the back and forth movement of design in X, Y direction; Two throw of crankshaft ends remain on the vertical plane, and the axis that has guaranteed the upper and lower cutter edge of a knife is on a vertical plane.The present invention has realized the little inertia design of last lower slide, has reduced complete machine weight when guaranteeing rigidity, and last lower slide connects by line slideway, is rolling friction between slide block and the slide rail, and it is little to wear and tear, and the gap is to not influence of shearing quality.

The specific embodiment

The present invention is in the two sides of machine pillar 8, and correspondence is offered axis hole, be horizontally disposed with in the axis hole two pairs parallel and on 6, two bent axles 6 of the bent axle on the same vertical plane, be arranged with gear 7 respectively, gear 7 present embodiments have adopted the design of clearance elimination gear group; Technical indicators such as the size dimension of sheathed gear 7, the number of teeth, modulus are all identical respectively on two bent axles 6; Gear 7 engagements on power set and the following bent axle 6.

The elbow section of four bent axles 6 on two columns 8 is corresponding in twos to be provided with, above the axis coaxial line respectively of a pair of bent axle 6 and following a pair of bent axle 6; Two elbow sections are connected with the two sides of upper tool post 2, lower slide 1 respectively, and the axis of two elbow sections is arranged on the same vertical plane, guarantee in the synchronous translation of directions X, and at this moment, upper and lower knife rest 2,1 is connected on two pairs of bent axles 6, the also not restriction of its upset free degree.At the fixedly connected riser 3 of the two ends of lower slide 1 difference, vertical fixing has slide rail 4 on riser 3; One slide block 5 is set on upper tool post 2, and slide block 5 drops into slide rail 4, and the turning cylinder of slide block 5 is parallel to the axis of bent axle 6.The present invention is arranged to two power output shafts with a power through gear mechanism, drive respectively and go up lower slide 2,1, simultaneously in order to guarantee that lower slide 2,1 motion mode is synchronous translational motion, between the last lower slide 2,1 linear slide mechanism is set, so claim double crankshaft slide rail synchronous mode flying shearing machine.Last lower slide 2,1 is little inertia design, reduce weight when guaranteeing rigidity, position of centre of gravity is partial to the centre of gyration as far as possible, to reach the purpose that reduces rotary inertia, last lower slide 2,1 connects by line slideway 4, for rolling friction, little, the gap of wear and tear does not influence shearing quality between slide rail 4 and the slide block 5.
