Description

The big taper big thickness coil holder device of line cutting

Technical field

The utility model relates to a kind of coil holder device of line cutting, especially the big taper big thickness coil holder device of line cutting.

Background technology

China's quick-wire-moving linear cutting machine realizes that the coil holder mechanism of tapering cutting is a single armed upper block movable type at present, and it mainly is made of wire storage tube and wiring frame; Single armed upper block movable type is that upper block moves, and lower tumbler is motionless, and when the taperings that carry out greater than 3 degree add man-hour, the centre of gyration of wire electrode is difficult to guarantee, the point of contact skew of wire electrode makes the cutting edge scale error of processing bigger, is difficult to satisfy the requirement of Mould Machining.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of precision machining is provided, can realizes the big taper big thickness coil holder device of the rocking lever formula line cutting of big taper big thickness processing.

The purpose of this utility model realizes by the following technical solutions, it mainly is made of wire storage tube and wiring frame, described wiring frame includes one and is connecting U respectively to planker and the V last turning cylinder to planker by last pivoted arm seat at least, the two ends that should go up turning cylinder are fixed with back guide wheel and last front jocket wheel respectively, also link to each other with lower guideway on it by at least one articulated swing arm, the lower guideway two ends also are fixed with down back guide wheel and following front jocket wheel respectively, and the intermediate active of swing arm is hinged on the fixing rotary support.

The described pivoted arm seat of going up also links to each other to planker with V to planker with U respectively by UV planker base, described swing arm two ends are connected with expansion link and following expansion link respectively, last expansion link is movably articulated on the turning cylinder, following expansion link is movably articulated on the lower guideway, and the centre of swing arm is hinged on the revolution back shaft on the rotary support.

Revolution back shaft plane on the described rotary support and workpiece processing edge of a knife face are on same plane.

On the utility model turning cylinder upper end be U to motion be V and be connected to planker with V to planker to the U that moves, the lower end connects lower guideway by swing arm, when U drives when going up the turning cylinder motion to planker to planker and V, lower guideway also movement therewith under the effect of swing arm, because swing arm is fixedly hinged on turning round on the back shaft, so the line of cut processing edge of a knife does not produce displacement, compared with prior art, the utlity model has compactness rational in infrastructure, safe and reliable, the precision machining height can be realized characteristics such as big taper big thickness processing purpose.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed explanation.

Mark shown in the accompanying drawing is: the 1-swing arm; The last back of 2-guide wheel; 3-V is to planker; 4-U is to planker; The last pivoted arm seat of 5-; The 5-bearing; The last turning cylinder of 6-; The last front jocket wheel of 8-; 9-UV planker base; 10-upper block frame; The last expansion link of 11-; The 12-rotary support; Expansion link under the 13-; The 14-lower tumbler; The 15-lower guideway; The 16-boom that rolls off the production line; 17-is the back guide wheel down; Draw a guide wheel under behind the 18-; 19-draws a wheel frame; Draw a guide wheel on behind the 20-; The 21-strainer; 22-rotary support spring bearing; 23-turns round back shaft; 24-centre of gyration line; The 25-wire electrode.

The utility model mainly is made of wire storage tube and wiring frame, described wiring frame includes one and connects respectively by U to planker and the V last turning cylinder to planker by last pivoted arm seat at least, the two ends that should go up turning cylinder are fixed with back guide wheel and last front jocket wheel respectively, also link to each other with lower guideway on it by at least one articulated swing arm, the lower guideway two ends also are fixed with down back guide wheel and following front jocket wheel respectively, and the intermediate active of swing arm is hinged on the fixing rotary support.

Shown in Figure 1, wire electrode (molybdenum filament) is drawn from wire storage tube 26, successively through tensioning guide wheel 21, back transition guide wheel 20,, go up back guide wheel 2, go up front jocket wheel 8, processing work 25, lower tumbler 14, down back guide wheel 17, get back to wire storage tube.Wherein, 19 is to install to draw the lead-in wire wheel frame that draws a guide wheel 18 under a guide wheel 22 and the back.

Be set with turning cylinder 7 between last front jocket wheel 8 and the last back guide wheel 2, last turning cylinder 7 is fixedly mounted on the upper block frame 10, also be provided with pivoted arm seat 5 on the last turning cylinder 7, be connected by bearing 6 between last rotation seat 5 and the last turning cylinder 7, on the last pivoted arm seat 5 fixedly UV planker base 9, U to planker 4 and V to planker 3, also be hinged with two ends on the last turning cylinder 7 and be provided with the swing arm 1 of

expansion link

11,13, the centre of swing arm 1 is hinged on the revolution back shaft 24, revolution back shaft 24 is fixed on the rotary support 12 by rotary support spring bearing 23, sees shown in Figure 2.

When tapering cuts, a planker such as the U of UV in the planker assembly obtains instruction to planker and drives last pivoted arm seat 5 fixed thereon during (or backward) motion forward and move forward and backward, the seesawing of last pivoted arm seat 5 drive with its last turning cylinder 7 that links together by rolling bearing and be fixed together go up guide wheel 2 afterwards, last front jocket wheel 8 moves forward and backward (being that U is to motion), and because last turning cylinder 7 is hinged with swing arm 1, and by last expansion link 11, following expansion link 13 and the following back guide wheel 17 that be fixed on lower guideway 15 roll off the production line boom 16 in and with it link together hinged with it, lower tumbler 14 carries out wraparound and changes the front and back U of fulcrum shaft 18 to motion, Fig. 3, Fig. 4 is exactly two kinds of extreme position working state schematic representations that move on this direction, make swing arm 1 like this, last back guide wheel 2, last front jocket wheel 8, wire electrode, lower tumbler 14, following back guide wheel forms a parallelogram planar linkage mechanism, make wire electrode U to vertical guide in form an angle and can realize tapering processing.

And the motion of V direction is to go up pivoted arm seat 5 by V to the planker drive to seesaw in the V direction, because the axis revolution of turning cylinder 7 meetings around oneself gone up in acting on of mechanism when seesawing, fixedly connected upward back guide wheel 2 thereon, and then it turns round an angle to last front jocket wheel 8 simultaneously, simultaneously because last turning cylinder 7 and swing arm 1 are to be rigidly connected to drive the following back guide wheel 17 that rolls off the production line boom 16 and lower guideway 15 and be fixed together in the V direction, lower tumbler 14,

rotary support

12,18 revolutions of following expansion link 13 whole wraparounds commentaries on classics fulcrum shaft, form appended Fig. 5, two kinds of extreme position working state schematic representations of Fig. 6 can be realized the cutting of big tapering and wire electrode can be from slippage in the guided wheel slot yet by such mechanism.
