Definitions

  • the invention relates to a press and forge mechanical engineering, and to mechanical presses and another press-forging machines in particular.
  • the mechanical press having a slide placed in bed guide rails, the slide is coupled to a crank shaft or eccentric shaft through a two-link rod and is tied with cylindrical balancers fixed to a bed; an electric motor is mounted on a machine bed and is connected through a flexible drive with a flywheel fixed rigidly on the above shaft; a slide has upper working position limit stop.
  • the press has a clutchless press actuating mechanism, installed on the bed, controls for a clutchless mechanism as well as a transfer mechanism made as a balancing lever, connected by a hinge with a two-link connecting rod (The Patent of Germany No 561059, 1934-03-19, IPC B30B1/26).
  • a mass of the actuating cylinder mechanism fixed to a hinge and protruding as a cantilever outside the machine bed zone will increase a value of dynamic loads applied to connecting rod links of a press crank group and on its bed due to alternating up and down swinging on a hinge.
  • a mechanical press which has a slide placed in bed guide rails, the slide is coupled to a crank shaft or eccentric shaft through a two-link rod and is tied with a balancer fixed to a bed; it has a limiter of a slide upper working position and also an electric motor located on a bed and connected through a flexible drive with a flywheel fixed rigidly on the shaft.
  • the press has a clutchless press actuating mechanism, installed on the bed, controls for a clutchless mechanism as well as transfer mechanism made as a balancing lever, connected hingedly with a two-link connecting rod (The Patent of Czechoslovakia No 135097, 1969-07-04, IPC B30b).
  • a mechanical press which is taken as a closest counterpart, comprising a slide placed in bed guide-rails, the above slide is connected with a crank shaft or eccentric shaft through a two-link rod and is tied with a cylindrical balancer fixed to a bed and to an elastic limiter of a slide upper position located in the above balancer and also an electric motor located on a bed and connected through a flexible drive with a flywheel fixed rigidly on the shaft, electromagnetic clutchless press actuating mechanism in a form of at least, one electrical magnet, consisting of a body and a movable armature, a transfer mechanism in a form of a balancer connected through a hinge with a two-link rod and also press controls.
  • the electrical magnet of the press clutchless actuating mechanism is located directly on a slide and as a result of this the said mechanism receives all dynamic loads (shocks, concussions, vibrations, oscillations) generated as a result of a slide work during cold sheet operations: cutting down, punching, cutting, bending, etc., that also reduces reliability, longevity and service life of a press actuating mechanism.
  • a power contact between a cone and a flag/balancer 47 of a two-link rod takes place at a magnetic action on command in both electromagnets of the armature 36 with a coil 35 of the body 34.
  • the technical objective of the invention is to increase a reliability, longevity and productivity of a press, to prolong its service life, to improve ecological cleanness and safety requirements during press operation.
  • the slide is coupled to a crank shaft or eccentric shaft through a two-link rod and is tied with a cylindrical balancer fixed to a bed and also with a resilient stopper of the slide upper position located inside the said balancer.
  • the press has also an electric motor located on a bed and connected through a flexible drive with a flywheel fixed rigidly on a shaft and an electromagnetic clutchless press actuating mechanism in the form of at least, one electromagnet which consists of a body and a moving armature, the transfer mechanism in the form of a balancer, connected by a hinge with a two-link connecting rod and also press control means, ACCORDING TO THE INVENTION, the moving armature of the electromagnetic clutchless actuating mechanism is made in the form of a double-crank arm mounted rotatably on the axis fixed to a machine frame; at that one arm of the armature lever located from the side of the press bed wall is mounted in such a way, that it can be mated with an electromagnet through a moving spring-loaded adjustable core having a platform and another armature lever arm is connected movably with the outer end of the transfer mechanism lever.
  • an electric motor located on a bed and connected through a flexible drive with a flywheel fixed rigidly on a
  • the slide initial upper position limiter in the form of a rod protruding from a piston in the upper cavity of the balancer cylinder.
  • An elastic ring with a through hole is mounted freely on this rod.
  • the mechanical press (Fig.1) has a slide 3 placed in guide rails of a machine frame 1 and connected with a balancer 2 installed on a machine bed, the said slide is coupled to a crank shaft or eccentric shaft through a two-link rod 5 with an upper 5 and lower 7 elbows.
  • the electric motor mounted on a machine frame 1 is connected by a flexible drive with a flywheel (they are not shown on Fig. 1 - 4), the flywheel is fixed rigidly on a crankshaft or eccentric axis 4.
  • a press clutchless electromagnetic actuating mechanism consists of an electromagnet 8, installed on a machine frame 1, the said electromagnet comprises a body 9 with an electromagnetic coil 10 with a core 11 inside it, a movable armature in the form of a two-arm lever 12, fixed with a possibility to rotate on the axis 13, the said axis is mounted on a press bed.
  • one arm 14 of the movable armature - two-arm lever 12 (see Fig. 1), located at a side of a press bed wall, is placed to ensure coupling with a platform 18 of a fixed core 11 of the electromagnetic coil 10 of the body 9 of the electromagnet 8.
  • This coupling possibility is realized with the help of the movable adjustable core 16 having a platform 17 placed in a lever.
  • Another arm 19 of the movable armature - two-arm lever 12 is movably connected via the axis 20 to the external end of the drive mechanism balancing lever 21 which is hingedly connected by its opposite end through the axis 22 with a two-link rod 5.
  • a slide upper working position limiter is made for example, from rubber in the form of an elastic ring 23 with a central through hole and the said ring is located loosely on a free end 25 of a rod 26 protruding from a balancer 2 of a piston 24 in the upper cavity of the balancer 2 cylinder 27.
  • the thickness of the elastic ring 23 is larger than the protruding from a piston 24 the end 25 of a rod 26 by the size of the damping gap.
  • the piston 24 loaded by a spring 28 and a rod 26 are connected through an axis 29 and brackets 30 with a slide 3.
  • a crankshaft 4 starts rotating in a usual way (with the help of a flexible drive and a flywheel) at starting an electric motor mounted on machine frame 1, when a crank begins to rotate in the opening of the upper elbow 6 of a two-link connecting rod 5.
  • a slide 3 is kept in this case in the extreme upper position with the action of a spring 28 of the balancer 2 through a piston 24, a rod 26, axis 29 and brackets 30.
  • the slide upper position is defined by the interaction of a piston 24, an elastic spring 23 and a bottom of a cylinder 27 of a balancer 2.
  • a movable armature - two-arm lever 12 together with a spring 15, core 16 and a platform 17 mounted in the said lever makes free swinging motions around axis 13 from the extreme left to the extreme right position as a result of action of rocking links 6 and 7 of the connecting rod 5 through the axis 22, balancer 21 and axis 20 onto an inner arm 19 of the movable armature - two arm lever 12.
  • the proposed invention enables to increase press reliability, longevity and output as well as to prolong its service life and simplify maintenance during operation.
  • This invention can be applied to manufacturing of new press and forge equipment and other types of machines with a crankshaft mechanism and can also be used for rebuilding various models and types of older press and forge machines in current operation.
