Description
Technical field
The present invention relates to a kind of metal forming machinery, relate in particular to a kind of dual connecting rod multiple position press.
Background technology
The middle-size and small-size punch press that at present domestic each big forging press factory produces is mainly based on single bar linkage structure, and table top is less, can only carry out single station or two or three station stamping, has very big limitation, has hindered the development of multistation mould, has influenced the production automation.Existing multiple position press such as Fig. 4, shown in Figure 5 generally comprise a bent axle, two slide block connecting rods, flywheel, clutch and motor.Motor and clutch are positioned at a side of bent axle, and the motor-driven clutch drives crankshaft rotating, and bent axle drives slide block by slide block connecting rod and moves up and down.When bent axle rotated, wheel action arrived away from the distance between the point of application of that end of flywheel less than this application point near the distance between the point of application of that end of flywheel in the application point and the forcing press of bent axle like this.
A this motor-driven forcing press, the torsional interaction of flywheel cause two point of applications to have phase difference in two point of applications, produce hysteresis, and the distance between two point of applications is big more, and it is serious more to produce hysteresis.As Fig. 4, shown in Figure 5, suppose that bent axle rotates along direction as shown, flywheel is at the right-hand member of bent axle, the point of application of flywheel on forcing press is made as A, B respectively, because the distance of flywheel to two point of application is different, bent axle is equivalent to a lever, when the moment of torsion of flywheel is delivered to two point of applications, two point of applications can produce certain phase difference, and slide block will occur tilting in motion process like this.
By the above as can be known, when slide block drops to lower dead center, because A point, B point are different with the distance of flywheel, the connecting rod of ordering near B will first stressed arrival lower dead center, will produce phase difference like this, make slider tilt, corresponding slider tilt phenomenon also can appear when slide block arrives top dead centre equally, cause the guide rail of both sides to be subjected to horizontal power, will produce friction between slide block and the guide rail, cause wearing and tearing, influence the forcing press precision, cause the forcing press unbalance loading to cause shorten the service life of forcing press and mould simultaneously, the precision of product also descends.
