Handle forcing press, it is relatively simple for structure, only it is made of a slider-crank mechanism, precision form, the precision for being unfavorable for part be low,
Vibrations are big, noise is big.
Utility model content
The utility model increases Liang Ge mechanisms, to change on the basis of traditional crank press slide block mechanism
The defects of conventional press part forming precision is low, noise is big, vibrations are big, operation is unstable.
The utility model is by the series connection of slider-crank mechanism, slider-rocker mechanism, floor mechanism to enhance mechanism
Flexible and precision, has reached deceleration, reinforcement effect, has reduced the vibrations generated in mechanism kinematic and noise.The slide crank
Block mechanism includes crank, master connecting-rod, guide runner first；The slider-rocker mechanism includes middle bar, strut, push rod, guide runner
Second；The floor mechanism includes lower push-rod, set square and sliding block third.It is guide runner first side vertically that the circular motion of crank, which transmits,
Upward reciprocating motion, then transmit as the reciprocating motion in guide runner second horizontal direction, it is the vertical side of sliding block third finally to transmit
Upward reciprocating motion, to carry out part processing.
The crank and rack, crank and master connecting-rod, master connecting-rod and guide runner first, middle bar and guide runner first, strut
With rack, middle bar strut and push rod, push rod and guide runner second, lower push-rod and guide runner second, lower push-rod and set square, triangle
Plate and rack, set square and output connecting rod, output connecting rod and sliding block third, are connected by revolute pair respectively.
Further, the crank is hinged with master connecting-rod one end, and the master connecting-rod other end is hinged with guide runner first；The branch
Bar is articulated with rack, and middle bar is hinged with guide runner first, and push rod is hinged with guide runner second, and middle bar, strut, three bar of push rod
It is articulated with a bit；Described set square one end is hinged with rack, and another both ends are respectively articulated with lower push-rod and output connecting rod；The lower push-rod
Hinged with guide runner second, the output connecting rod is hinged with sliding block third.
The utility model has the beneficial effects that due to the transmission of multi link so that forcing press operation is more steady, noise drop
It is low, so that forcing press is had the characteristics that reinforcement, deceleration, high-precision, high flexibility.
Description of the drawings
Fig. 1 is the utility model multi-connecting-rod mechanism kinematic sketch；
Fig. 2 is the utility model multi-connecting-rod mechanism mirror movements schematic diagram.
In figure, 1- racks, 2- cranks, 3- master connecting-rods, 4- guide runner first, bar in 5-, 6- struts, 7- push rods, 8- is oriented to
Sliding block second, 9- lower push-rods, 10- set squares, 11- export connecting rod, 12- sliding blocks third.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
It is the kinematic sketch of mechanism of the utility model as shown in Figure 1, provided by the utility model is that one kind applying to pressure
The multi-connecting-rod mechanism of machine.It is formed by a slider-crank mechanism, slider-rocker mechanism and floor mechanisms in series；Slider-crank mechanism
Including crank 2, master connecting-rod 3, guide runner first 4；Slider-rocker mechanism includes middle bar 5, strut 6, push rod 7, guide runner second 8；
Floor mechanism includes lower push-rod 9, set square 10 and sliding block the third 12.
Crank 2 is hingedly fixed in rack 1, can be moved in a circle under the driving of motor around fixed point, master connecting-rod 3 and song
Handle 2 is hinged, and guide runner first 4 is hinged with master connecting-rod 3, and guide runner first 4 is hinged with rack 1, and limitation can only be in the vertical direction
The rotation of movement, crank 2 drives the lower movement in the vertical direction of guide runner first 4 by master connecting-rod 3.Strut 6 is articulated with rack 1
On, middle bar 5 is articulated in guide runner first and is hinged with strut 6, and then the up and down motion of guide runner first 4 passes through 5 band of middle bar
Dynamic strut 6 is swung around fixed point to move reciprocatingly.Push rod 7 is articulated with a bit with middle bar 5 and strut 6, while being cut with scissors with guide runner second 8
It connects, guide runner second 8 is hinged with rack 1, and limitation can only move in the horizontal direction, and 7 band of push rod is swung by strut 6
Action-oriented sliding block second 8 does bilateral reciprocation in the horizontal direction.Set square 10 is hinged in rack 1, and one end is hinged lower push-rod 9,
9 other end of lower push-rod and guide runner second 8 are hinged, and one end hingedly exports connecting rod 11, and output connecting rod 11 and sliding block the third 12 is hinged, sliding
Block the third 12 is hinged with rack 1, and limitation moves in the vertical direction, and the lower push-rod 9 that reciprocates through of guide runner second 8 drives three
Gusset 10 does the reciprocating motion swung, and then is done in vertical direction with movable slider the third 12 by exporting connecting rod 11 and up and down reciprocatingly transported
It is dynamic, and then workpieces processing.
Mirror image is carried out to this mechanism, obtains a more stable novel multi-connecting-rod mechanism, it is possible to reduce forcing press is used to
Property power, vibrations etc..As shown in Figure 2.
