Abstract
The invention relates to a low-speed pressing mechanism with a large force increasing stroke. The mechanism comprises a driving mechanism, a guide rail of the driving mechanism and two driving blocks symmetrically arranged on the guide rail, wherein symmetrical swing-link input type force increasing mechanisms are arranged between the driving mechanism and double-toggle-rod force increasing mechanisms; the double-toggle-rod force increasing mechanisms are arranged in bilateral symmetry and fore-and-aft symmetry below a rack. Based on the cooperation of the two grades of force increasing mechanisms, a large force increasing effect is achieved in a lower dead point working area, and the defect that the traditional force increasing mechanism has a short effective force increasing stroke is overcome. With the progress of the work, the amplification factor gets larger and larger, and thus the power of a power source is reduced effectively. Due to the adoption of a symmetrical structure, unbalance loading is eliminated; and the mechanism provided by the invention has the advantages of high-speed feeding in a no-load process, fast return, high working efficiency and wide application range, and can press a part at a low speed so as to ensure the quality and accuracy of part forming.

A kind of low speed is suppressed the force-stroke mechanism of heightening, and comprises driving mechanism, is provided with symmetrical fork input type boosting mechanism between driving mechanism and the duplex bar boosting mechanism;
Driving mechanism is made of first driving block 2, second driving block 4 and guide rail 3, and guide rail 3 is laterally placed, and first driving block 2 and second driving block 4 are configured on the guide rail 3;
Duplex bar boosting mechanism about the bottom of frame 1, front and back are symmetrical arranged, upper elbow lever 6 respectively with an end of the bottom of frame 1 and lower link 7 by being articulated and connected, lower elbow lever 8 is connected with upper elbow lever 6 with output terminal 9 respectively by hinged;
One end of the last connecting rod 5 of symmetry fork input type boosting mechanism is hinged with first driving block 2 or second driving block 4, the other end of last connecting rod 5 be connected equilibrium block 10 connections, lower link 7 pass through hinged respectively be connected equilibrium block 10 and be connected with upper elbow lever 6.
The present invention has the following advantages:
One, has unloaded fast feed, return advantage rapidly, high working efficiency;
Two, can the low cruise compacted part, guaranteed the quality and the precision of forming parts;
Three, adopt the secondary boosting mechanism, in the lower dead centre working zone, have big reinforcement effect, overcome the short shortcoming of the effective reinforcement stroke of traditional boosting mechanism, can be applicable to that various main equipments process big part, applied widely, more adapt to the demand of modern large-tonnage equipment.

Embodiment
Below in conjunction with accompanying drawing the present invention is done detailed description.
With reference to Fig. 1, a kind of low speed is suppressed the force-stroke mechanism of heightening, and comprises driving mechanism, is provided with symmetrical fork input type boosting mechanism between driving mechanism and the duplex bar boosting mechanism;
Driving mechanism is made of first driving block 2, second driving block 4 and guide rail 3, guide rail 3 is laterally placed, first driving block 2 and second driving block 4 are configured on the guide rail 3, first driving block 2 and second driving block 4 can be along guide rail 3 left and right sides to-and-fro motion, first driving block 2 and second driving block 4 be same moved further simultaneously, satisfy the job requirement of symplex structure, the power form of driving block can be that motor is by various forms of drivings such as leading screw promotion, hydraulic drives.
Duplex bar boosting mechanism about the bottom of frame 1, front and back are symmetrical arranged, upper elbow lever 6 respectively with an end of the bottom of frame 1 and lower link 7 by being articulated and connected, lower elbow lever 8 is connected with upper elbow lever 6 with output terminal 9 respectively by hinged; Upper elbow lever 6 is under the impetus of lower link 7 during work, force upper elbow lever 6 to laterally rotate, and then drive lower elbow lever 8 moves, because the articulating point of lower link 7 and upper elbow lever 6 is below the articulating point of upper elbow lever 6 and lower elbow lever 8, can make the toggle link reinforcement effect more remarkable like this, particularly when the approaching end of work, last lower elbow lever is vertically approaching, becomes to obtain very big amplification power under the effect of lower link 7 less power.
One end of the last connecting rod 5 of symmetry fork input type boosting mechanism and first driving block 2 or second driving block 4 are hinged, the other end of last connecting rod 5 be connected equilibrium block 10 and connect, lower link 7 by hinged respectively be connected equilibrium block 10 and be connected with upper elbow lever 6, horizontal impulse and the Driving force of 5 pairs first driving blocks 2 of last connecting rod and the mutual balance of active force of 1 pair first driving block 2 of frame of 2 pairs of outer bound pair first driving blocks during work, according to condition of balance on force as can be known, the active force of 5 pairs first driving blocks 2 of last connecting rod active force main and 1 pair first driving block 2 of frame is cancelled out each other, therefore, the Driving force of outer bound pair first driving block 2 only needs to urinate very much and can produce very big power on last connecting rod 5, plays reinforcement effect; About symmetry fork input type boosting mechanism, front and back all are that symmetry is placed, and make wholely stressedly evenly when work, to connect equilibrium block 10 because left-right and front-back all is a symmetrical mechanism, and it is vertically moved back and forth up and down, can deflection.
Working principle of the present invention is:
With reference to Fig. 2, driving mechanism is to the impetus of first driving block 2 and the position limit of 1 pair first driving block 2 of frame, make symmetrical first driving block 2 and second driving block 4 move accurately to the centre simultaneously along guide rail, first driving block 2 drives upward, and connecting rod 5 moves simultaneously, make the connection equilibrium block 10 that is connected with last connecting rod 5 move straight down, this moment is because the effect of symmetrical fork input type boosting mechanism, be converted into the power straight down that connects on the equilibrium block 10 that acts on after making horizontal applied force amplify certain multiple, when connection equilibrium block 10 moves down, driving lower link 7 moves, lower link 7 promotes upper elbow lever 6 simultaneously and laterally rotates, upper elbow lever 6 drives lower elbow lever 8 and moves, and then lower elbow lever 8 drive output terminals 9 are moved down, under the effect of upper elbow lever 6 and lower elbow lever 8 and lower link 7, make and act on the output terminal 9 after acting on the active force straight down that connects on the equilibrium block 10 amplifies certain multiple, reached required ouput force, with reference to Fig. 3, through cooperatively interacting of secondary boosting mechanism, make entire work process system magnification factor all very big, effectively reduce the power of power source, when work, can be by the travelling speed of controlling and driving piece, reach required various working conditions, after hours, first driving block 2 and second driving block 4 are simultaneously to both sides while fast moving, can make output terminal 9 return to initial position rapidly, increase work efficiency, whole forming process needed time is short, the efficient height.
