It is the first embodiment provided by the utility model as shown in Figure 1 to Figure 3, the present embodiment is that one kind has dynamic balancing
The punch press of device, including transmission component, connecting rod 2, eccentric wheel 3, dynamic balance weight 4 and upper cover of rack plate 7, bent axle 1, connecting rod 2, bias
Wheel 3 and dynamic balance weight 4 form the dynamic poise device of whole punch press.
In the dynamic poise device of punch press described above, transmission component includes bent axle 1, and the both sides of bent axle 1 are provided with crank arm 10, bent
The both ends of armshaft 10 are connected to two eccentric wheels 3 symmetrical and that eccentric direction is opposite with the eccentric direction of bent axle 1, two eccentric wheels
3 are connected by bearing with the eccentric wheel mounting hole 21 of two lower ends of connecting rod 2, and the central area interval of plane is set on dynamic balance weight 4
There are two square openings for being through to lower end 42, two square openings 42 connect two connecting rods 2, dynamic balance weight by same fix bar
A manhole 41 being connected with square opening 42 is provided among 4 left and right sides, dynamic balance weight 4 passes through consolidating in manhole 41
Fixed pole is connected with the fix bar mounting hole 20 of the upper end of connecting rod 2, and two symmetrical connecting rods 2 are same solid by sharing with dynamic balance weight 4
Fixed pole, a part manufacturing cost is not only saved, and can ensure that manhole 41 is co-axially mounted with fix bar mounting hole 20, partially
The diameter of heart wheel mounting hole 21 is more than the diameter of fix bar mounting hole 20, and the folding corner region of dynamic balance weight 4 is tiltedly additionally provided with two upper guide post holes
40, two guide column sleeves 5, the central junction line and two upper guide posts 40 of two square openings 42 are correspondingly provided with two upper guide post holes 40
Central junction line be not arranged on the same straight line, but in approximately the same plane.
The punch press of above-mentioned dynamic poise device also includes upper cover of rack plate 7, and plane is provided with Qian connected in star on upper cover of rack plate 7,
The two of which folding corner region of Qian connected in star is respectively equipped with the lower guide pillar hole 70 corresponding with the position of upper guide post hole 40, upper guide post hole
40 is coaxial with lower guide pillar hole 70, and guide pillar 6 connects dynamic balance weight 4 and upper cover of rack plate 7 through upper guide post hole 40 and lower guide pillar hole 70
Pick up and, the forward edge of upper cover of rack plate 7 is provided with the rib extended downwardly, and rib front end is provided with vertical with punch press working face
Punch press front end face 71, left and right is respectively equipped with the punch press left side 72 vertical with punch press working face, punch press right side 73.
Because punch press board size and model are variant, cause the size of frame of punch upper cover plate 7 and dynamic balance weight 4 by
Limitation, while in view of the assembly problem of other parts on dynamic balance weight 4, the position for ultimately resulting in guide pillar hole is restricted, this
In embodiment, two upper guide post holes 40 or the central junction line of lower guide pillar hole 70 or guide pillar 6 tilt relative to lathe front end face 71
Angle is 25 degree~40 degree.
In summary, the utility model improves punch press by changing punch press dynamic poise device and upper cover plate guide pillar hole site
Stationarity, it is arranged at intervals by original middle part and is changed to the setting of folding corner region diagonally opposing corner, i.e., wherein once guide pillar hole 70 is simultaneously close
Punch press front end face 71 and punch press left side 72, another lower guide pillar hole 70 are moved away from end face before punch press 71 and punch press left side 72
Guide pillar hole 70 is set under upper guide post hole 40 and the position correspondence of guide pillar 6 on balance weight 4, the central junction line of two square openings 42 with
The central junction line in two upper guide post holes 40 is generally aligned in the same plane but not conllinear.Dynamic balance weight 4 is in by two central junction lines
