Lower end is fixedly connected by lower connecting pin with sliding block top.
Further, the kidney ellipsoid endoporus on the curved bar top contains the axle journal of bent axle one end, and sliding block is in upper dead center position
When, the distance of kidney ellipsoid endoporus peak of the axle journal upside away from curved bar is more than 25mm~30mm；Sliding block is in lower dead point position, axle
The distance of the kidney ellipsoid endoporus minimum point away from curved bar is more than 25mm~30mm on the downside of neck.
Further, the center line of balance cylinder piston rod-curved bar of the sliding block both sides and the shank hole center of sliding block
The blanking centerline hole of line and working plate is in same vertical plane.
Further, the air pressure of the rod chamber of balance cylinder is 0.5MPa~0.6MPa, and the rodless cavity of balance cylinder is logical big
Gas.
The present invention uses and has been symmetrical arranged balance cylinder arranged in a straight line from top to bottom, transition segment and curved bar in sliding block both sides
Structure, and balance cylinder is vertically fixed on the fuselage top of open type crank press.Curved bar is spelled using two to extension bar
The structure connect, is easily installed and repairs, and curved bar lower end is fixedly connected with upper end of slide block, so as to solve opening for lateral arrangement bent axle
The problem that formula crank press bascule is installed and repaired.When can prevent slide block down, because the weight of its deadweight and mould is led
Cause shock and noise that the reverse stress of travelling gear is produced.The gap between connecting rod and sliding block is eliminated, rushing for stress part is reduced
Hit and wear and tear.The power consumption of height of packing compact adjustment mechanism can be also reduced, while being also prevented from because of brake failure or connecting rod
When fractureing, sliding block falls and generation accident.

Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Fig. 1~Fig. 6, the present embodiment is symmetricly set on the both sides of sliding block 10 including two groups and straight line is arranged from top to bottom
Balance cylinder 1, transition segment 2 and the curved bar 3 of row, each lower end of balance cylinder 1 are supported on former and later two support bases 4, two branch
Support seat 4 is vertically fixed on the top of fuselage 20 of open type crank press.The head of balance cylinder piston rod 11 passes through fuselage roof
201 are fixedly connected with the upper end of transition segment 2, and the lower end of transition segment 2 is hinged with the upper end of curved bar 3 by upper swivel pin 5.Transition segment 2 includes
The screwed hole 21 of upper end and the notch 22 of lower end, the head of balance cylinder piston rod 11 are consolidated through fuselage roof 201 with screwed hole 21
Fixed connection, and by nut 23 and tightly.
The top of curved bar 3 of the present embodiment is in kidney ellipsoid, and straight line shank 31 is extended in bottom, including first pair of extension bar 31 and the
Two pairs of extension bars 32, first pair of extension bar 31 is in that top is the spoon shape that half kidney ellipsoid bottom is straight line shank 311, and second pair of extension bar 32 is in
Half kidney ellipsoid, the two ends of first pair of kidney ellipsoid of 31 top of extension bar half and the two ends of second pair of kidney ellipsoid of extension bar 32 half each other it is chimeric into
Complete kidney ellipsoid.As shown in Figures 2 and 3, in the present embodiment, the two ends of first pair of kidney ellipsoid of 31 top of extension bar half are fork
Shape 311, second pair of two ends of extension bar 32 are flat board 321, when two and half kidney ellipsoids are docked, and flat board 321 is injected in fork-shaped 311.It is right
In the notch 22 of the upper end insertion transition segment 2 of first pair of extension bar 31 and second pair of extension bar 32 after connecing, pass through upper swivel pin 5 and mistake
2 lower ends of section are crossed to be hinged.The kidney ellipsoid lower end that first pair of extension bar 31 and second pair of extension bar 32 are pieced together is fixed by middle connecting pin 6 to be connected
Connect.As shown in figure 4, the lower end of straight line shank 311 and lower one end of connecting pin 7 are fixedly connected by the way that the first holding screw 8 is vertical, lower company
The other end of pin 7 is fixedly connected with the otic placode 101 of the top side of sliding block 10 by the second holding screw 9, the He of the first holding screw 8
Second holding screw 9 can prevent the axial movement of lower connecting pin 7.The top of curved bar 3 is alternatively rectangle or other shapes.
As shown in Figure 5 and Figure 6, the center line E-E of 11-curved bar of balance cylinder piston rod 3 of the both sides of sliding block 10 and sliding block 10
The center line of shank hole 101 and working plate 40 the center line of material-dropping hole 401 in same vertical plane, it is descending flat in sliding block 10
Weigh and the mobile accuracy of sliding block 10 is improved when cylinder 1 is buffered, improve the stamping quality of product, extend the mold use life-span.
The top of curved bar 3 is enclosed on corresponding crankshaft journal 301.During open type crank press machine operation, with turning for bent axle 30
Dynamic, sliding block 10 is also moved up and down therewith, drives the curved bar 3 of its both sides to move up and down.When sliding block 10 is in upper dead center position, axle journal
The peaks of kidney ellipsoid endoporus 33 away from curved bar 3 is more than 25mm~30mm apart from F on the upside of in the of 301；When sliding block 10 is in lower dead point position
When, kidney ellipsoid endoporus 33 minimum point of the downside of axle journal 301 away from curved bar 3 is more than 25mm~30mm apart from G, and curved bar 3 all the time will not
Interfered with axle journal 301.
When sliding block 10 is descending, the upper end of curved bar 3 of its both sides pulls piston rod 11 to move down by transition segment 2 so that flat
The air pressure of the weighing apparatus rod chamber of cylinder 1 moves down cushioning effect to sliding block 10 and mould, can prevented to be increased to 0.5MPa~0.6MPa
Decline because sliding block 10 is conducted oneself with dignity and rapidly, make the reverse stress of the gear in transmission system and cause to hit and produce noise, reduce by
The impact and abrasion of power part, reduce the power consumption of height of packing compact adjustment mechanism, and the rodless cavity of balance cylinder 1 leads to air.
In addition to the implementation, the present invention can also have other embodiment, all use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
