Description
Technical field
The present invention is related with the balancer of punching machine, particularly relates to a kind of punching machine of tool automatic adjustable balance device.
Background technology
As shown in fig.1, for a kind of existing punching machine 10 of tool balancer, including：Engine base 11, one can move back and forth up and down to
It is set to the sliding block group 12 of the engine base 11, the connecting rod 14 and a power of a bent axle 13, one the connection bent axle 13 and the sliding block group 12
Connect the driving unit (not showing on figure) of the bent axle 13.The bent axle 13 is driven to rotate by the driving unit, you can to drive this
Sliding block group 12 drives the mold 15 to move back and forth up and down and then carries out stamping press to materials and parts.
In general, 14 upside of connecting rod is equipped with lateral through-hole 141, bent axle 13 passes through through-hole 141 to be rotated with connecting rod 14
Connection, in order to reduce frictional force, the hole wall of the through-hole 141 of connecting rod 14, which is equipped with, closes copper 16, and connecting rod 14 is by closing copper 16 and bent axle
13 contacts, due to the weight relationships of sliding block group 12 etc., bent axle 13 and the contact surface for the downside for closing copper 16 can have certain gap,
When there is load effect, which moves downwards and vibration or noise occurs, and in order to avoid the above situation, and makes sliding block group
12, mold 15, connecting rod 14 and bent axle 13 weight balancing, make its stable movement, be round and smooth, punching machine is additionally provided with two balancers 17,
Two balancers 17 are respectively arranged on the left and right sides of engine base 11, and common balancer 17 is oil hydraulic cylinder or pneumatic cylinder, and two flat
The body of rod 171 of weighing apparatus 17 is connect with the upside of sliding block group 12 respectively, overcomes sliding block group 12, mould by the pulling force of balancer 17
The gravity of tool 15, connecting rod 14 and load makes bent axle 13 be contacted steadily with copper 16 is closed.
In addition, punching machine is typically provided punching machine display screen (not showing on figure), every operation ginseng for showing, setting punching machine
Number, but there is also following shortcomings for this punching machine：Punching machine commissioning staff is to estimate sliding block according to the theoretical value that designer provides
The weight of 12, mold 15, connecting rod 14 and bent axle 13 is organized to set the output of balancer 17, or even is sometimes passed through only according to individual
Test and the output of the motion conditions sets itself of sliding block group 12 adjustment balancer 17, the weight of theoretical calculation often with actually have compared with
Big to come in and go out, the personal experience without same commissioning staff is different, and often setting value difference is larger, and when more mold exchange 15, may
Forget the output of balancer 17 to be readjusted or since limited experience can not be adjusted correctly, above-mentioned several situations may
Cause the output of balancer 17 to set inaccurate, the junction local strength overload of conjunction copper 16 and bent axle 13 can be made, make conjunction
Copper 16 is easily worn away；Keep conjunction copper 16 and 13 local gap of bent axle too small, causes to generate heat, or even kill phenomenon；Local pyrexia will produce
Additional energy expenditure keeps the input power of main motor insufficient, influences the precision of stamping products.
