Abstract
The utility model relates to a toggle brim pressing mechanism which is suitable for hydraulic stretching machines. The utility model is provided with a synclastic toggle mechanism. The upper end of the synclastic toggle mechanism is hinged with a lower brim pressing cross beam, and the lower end is hinged with a bottom beam of a machine base. A connecting rod is connected with the rotating axles of each toggle joint. A lying oil cylinder is hinged with the machine base. A piston rod is hinged with the connecting rod. The toggle mechanism is driven by an oil cylinder to realize the brim press, and lowers down the lowest height limited of the lower brim pressing cross beam to enlarge the progress and reduce the volume of the oil cylinder and complete machine. The pressure is not kept by the oil, and the brim pressing force is stabilized. The utility model has the advantages of convenient operation and installation and obvious energy and material saving. The special high speed variable speed motion mode formed by the mechanism is more suitable for the actual working need of the stretching machine.
Description
The utility model relates to the forging machine tool technical field, particularly a kind of hydraulic pressure toggle link blank body that is applicable to hydraulic tensioner.
China Patent No. ZL90215289.0 disclosed " novel hydraulic drawing press " is to overlap the blank body that dual-elbow-bar mechanisms are formed hydraulic drawing presses with an oil cylinder and two that uprightly is installed on the support bottom girder, and it reaches the flanging purpose by the hydraulic oil cylinder driving elbow-bar mechanism.Because elbow-bar mechanism has the amplification and the self-locking action of power, thereby dwindled oil cylinder, simplified oil circuit, have energy-saving material-saving, do not need the repairing pressurize, advantage such as operating efficiency height.But the blank body of this patent still has deficiency: the stroke of blank body is subjected to the restriction of flanging sill size, and desire increases stroke, must increase flanging sill size, brings increasing considerably of machine volume and manufactured materials thereupon; Because oil cylinder is uprightly installed and need be occupied certain altitude, the design feature of crooked in opposite directions dual-elbow-bar mechanism in addition, the lower bound height of flanging sill is difficult to further reduction, if increase the stretching depth of stretching-machine, must increase the size of flanging sill except that above-mentioned, its lower bound height also increases thereupon, and this gives whole machine installation, and the loading and unloading and the production operation of mould, workpiece are made troubles; Moreover, because the length and the amplitude of fluctuation of this elbow-bar mechanism are subjected to the limitation in space, place, its amplification to the power and the speed of service also is restricted, fail fully to be brought into play.
The purpose of this utility model is to overcome the deficiency of above-mentioned blank body, improve the structure of elbow-bar mechanism and the mounting means of oil cylinder, under the situation that does not increase flanging sill size and lower bound height, increase the stroke of blank body, provide a kind of performance more superior hydraulic pressure toggle link blank body.
Hydraulic pressure toggle link blank body described in the utility model, mainly contain support, the flanging sill, elbow-bar mechanism, oil cylinder, support is formed, wherein the upper end of elbow-bar mechanism is hinged with the support that is fixed under the flanging sill, the lower end is hinged with the support that is fixed on the support bottom girder, there is a connecting rod to be connected with rotating shaft in each elbow-bar mechanism toggle, by cylinder body, the oil cylinder accumbency that piston and piston rod are formed is provided with, hinged with the support that is fixed on the support side, the piston rod front end is through connected body and rod hinge connection, by the hydraulic oil cylinder driving elbow-bar mechanism, drive the lifting of flanging sill, reach the flanging effect, realize the purpose of this utility model thus.
Advantage of the present utility model is: 1, the oil cylinder that will uprightly be provided with changes the swing-type cylinder that accumbency is provided with into, and its below from the flanging sill moved to flanging sill one side, reduced the spatial altitude that former oil cylinder occupies, thereby reduced the lower bound height of crossbeam, be convenient to whole machine installation and production operation; 2, change into crooked in opposite directions elbow-bar mechanism crooked in the same way, in the space of equal height, can increase the length and the amplitude of fluctuation of elbow-bar mechanism, strengthened the stroke of blank body, overcome the drawback that former blank body stroke is subjected to flanging sill size constrained, thereby reduced machine volume and weight, economical with materials is obvious; 3, because the improvement on the said structure makes elbow-bar mechanism further obtain performance to the amplification of the power and the speed of service, on the one hand, dwindling oil cylinder, need not under the situation of repairing pressurize, making pressure-pad-force stable, energy-saving effect is obvious; On the other hand, the high speed variable motion in the flanging sill lifting process that forms of mechanism more meets the needs of stretching-machine real work thus.
The utility model is applicable to that various stretching-machines and forcing press make blank body, also can make the machinery equipment of straight line variable motion or similarly uses in the clamping device at various need.
Further specify architectural feature of the present utility model and operation principle below in conjunction with accompanying drawing embodiment.
Fig. 1 is the structural representation of hydraulic pressure toggle link blank body described in the utility model.A certain motion state when heavy line is described the blank body lifting among the figure; The movement locus of its toggle when the elbow-bar mechanism bending is described in double dot dash line.
That Fig. 1 describes is an embodiment of the present utility model, it mainly contains support (1), flanging sill (5), elbow-bar mechanism, oil cylinder, support is formed, flanging sill (5) by the guide rail of stretching-machine support (1) or on support vertically installed guide pillar, by upper boom (16) and lower beam (12) form two the cover elbow-bar mechanism, its upper end is hinged with the support (6) that is fixed under the flanging sill (5), its lower end is hinged with the support (11) that is fixed on the support bottom girder (1 '), cylinder body (7) is arranged, piston (8), the oil cylinder that piston rod (10) is formed is hinged with the support (9) that is fixed on support (1) side, the oil cylinder accumbency is provided with, can support (9) for the axle center swings up and down, piston rod (10) front end is hinged through connected body (15) and connecting rod (14).
The above-mentioned technical characterictic of the utility model can correspondingly be done following variation, and they all do not depart from essence of the present utility model.For example, according to the actual needs of stretching-machine, the elbow-bar mechanism that constitutes blank body can adopt a cover, two covers or many covers; Oil cylinder can substitute with power-actuated screw pair.
Operation principle of the present utility model is: the left chamber oil-feed of oil cylinder, oil pressure makes piston (8) move right together with piston rod (10), connecting rod (14) moves to the upper right side thereupon, impelling upward, lower beam (16,12) is that rotate in the axle center with support (6,11) respectively, the toggle (13) that is elbow-bar mechanism clockwise rotates along the arc track shown in the double dot dash line among the figure, along with elbow-bar mechanism turns to straight and upright by case of bending gradually, flanging sill (5) is pushed to rising, mould (2,4) compresses stretched part (3) about impelling, and realizes the flanging function.Otherwise when piston (8) is moved to the left, piston rod (10) drivening rod (14) below left moves, and elbow-bar mechanism turns to bending gradually by straight and upright, and flanging sill (5) moves down, and mould (2,4) unclamps up and down, ejects workpiece (3).
