A high-power motor with fixed rotating speed is utilized to drive the two same toggle rod mechanisms simultaneously, and the punch hammer has the work properties of high efficiency, large tonnage and flexibility.

Description

A kind of duplex bar punching machine
Technical field
The utility model relates to the metal forming process equipment that does not have cutting, specifically, relates to a kind of duplex bar punching machine.
Background technology
Punching machine is a kind of important metal forming process equipment, and it has characteristics such as high efficiency, good work environment, maintaining convenience, in commercial production, is widely used.The operating mechanism of traditional mechanical forcing press is a slider-crank mechanism, and this forcing press is too high in workpiece deformation stage block stamp speed, can not satisfy the requirement of high-quality stamping press.At present, servo-pressing machine and combination drive forcing press have appearred in operating rate and raising punching machine service behaviour in order to reduce block stamp.Servo-pressing machine can improve crudy, the expansion forcing press range of work of workpiece, but because the servomotor price is very expensive, therefore the manufacturing cost of this forcing press is very high.The combination drive forcing press adopts a servomotor and a common motor driven in common linkage; Common electric machine provides main kinetic energy; Servomotor is realized the adjustment of block stamp position and speed; Therefore but this kind forcing press still exists the excessive problem of slide block speed governing amplitude, is difficult to satisfy in the processing requirement to the block stamp operating rate.
The utility model content
The purpose of the utility model is to be difficult to above-mentioned deficiencies such as adjusting and service behaviour difference to existing metal forming with cost height, the slide block operating rate that forcing press exists; The utility model provides a kind of duplex bar punching machine; This forcing press is decided the rotating speed motor and is driven the identical elbow-bar mechanism of two covers simultaneously by high-power, can make block stamp have high efficiency, than large-tonnage and flexible operating characteristic.
The technical scheme of the utility model is: a kind of duplex bar punching machine; Connect by the identical left and right sides elbow-bar mechanism of two covers between the right elbow-bar mechanism that described forcing press comprises frame, be made up of eccentric gear and connecting rod and upper elbow lever and lower elbow lever, left elbow-bar mechanism and the block stamp formed by eccentric gear and connecting rod and upper elbow lever and lower elbow lever, frame and block stamp; Left and right sides elbow-bar mechanism is symmetrically distributed in the both sides of frame; Eccentric gear in the right elbow-bar mechanism and the eccentric gear in the left elbow-bar mechanism are meshing with each other; The eccentric gear of right elbow-bar mechanism is connected with frame by revolute pair; Eccentric gear is connected with connecting rod by revolute pair; Connecting rod, upper elbow lever and lower elbow lever are connected in the same revolute pair of sentencing, and upper elbow lever is connected with frame by revolute pair, and lower link is connected with block stamp by revolute pair; The eccentric gear of left side elbow-bar mechanism is connected with frame by revolute pair; Eccentric gear is connected with connecting rod by revolute pair; Connecting rod, upper elbow lever and lower elbow lever are connected in the same revolute pair of sentencing, and upper elbow lever is connected with frame by revolute pair, and lower link is connected with block stamp by revolute pair; Block stamp is within the fixed guide, links to each other by moving sets with frame.
The beneficial effect of the utility model is: the utility model utilizes high-powerly to be decided the rotating speed motor and drives the identical elbow-bar mechanism of two covers simultaneously, can make block stamp have high efficiency, than large-tonnage and flexible operating characteristic.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
The specific embodiment of the utility model as shown in Figure 1; A kind of duplex bar punching machine; Connect through the identical left and right sides elbow-bar mechanism of two covers between the right elbow-bar mechanism that described forcing press comprises frame 2, be made up of eccentric gear 1 and connecting rod 3 and upper elbow lever 4 and lower elbow lever 5, left elbow-bar mechanism and the block stamp 6 formed by eccentric gear 7 and connecting rod 8 and upper elbow lever 9 and lower elbow lever 10, frame 2 and block stamp 6; Left and right sides elbow-bar mechanism is symmetrically distributed in the both sides of frame 2; Eccentric gear 1 in the right elbow-bar mechanism is meshing with each other with the eccentric gear 7 in the left elbow-bar mechanism; The eccentric gear 1 of right elbow-bar mechanism is connected with frame 2 through revolute pair; Eccentric gear 1 is connected with connecting rod 3 through revolute pair; Connecting rod 3, upper elbow lever 4 and lower elbow lever 5 are connected in the same revolute pair of sentencing, and upper elbow lever 4 is connected with frame 2 through revolute pair, and lower link 5 is connected with block stamp 6 through revolute pair; The eccentric gear 7 of left side elbow-bar mechanism is connected with frame 2 through revolute pair; Eccentric gear 7 is connected with connecting rod 8 through revolute pair; Connecting rod 8, upper elbow lever 9 and lower elbow lever 10 are connected in the same revolute pair of sentencing; Upper elbow lever 9 is connected with frame 2 through revolute pair, and lower link 10 is connected with block stamp 6 through revolute pair; Block stamp 6 is within the fixed guide, links to each other through moving sets with frame 2.
During work; Eccentric gear 1 rotates under the high-power drive of deciding the rotating speed motor; For forcing press provides kinetic energy, under the effect of rotatablely moving of eccentric gear 1, eccentric gear 7 is done and eccentric gear 1 reverse rotatablely moving; Under the drive of eccentric gear 1, connecting rod 3, upper elbow lever 4, lower elbow lever 5 are done plane motion, dead axle swing and plane motion respectively; Under the drive of eccentric gear 7, connecting rod 8, upper elbow lever 9, lower elbow lever 10 are done plane motion, dead axle swing and plane motion respectively; In this process, block stamp 6 also setting in motion under the acting in conjunction of lower link 5 and lower link 10, because it is spacing to receive the horizontal direction of guide rail, and lower link 5 is hinged again with lower link 10 and block stamp 6, so block stamp 6 can only punching press up and down in guide rail.
