Abstract
The utility model discloses a force balancing device for a crankshaft of a high-speed precision punch, comprising a crankshaft which comprises a crank and an eccentric shaft arranged on the outer surface of the crank, wherein the outer surface of the crank is also provided with a balance block; the longitudinal section of the balance block is sector-shaped; and the side wall of the eccentric shaft farthest away from the crank is opposite to the arc-shaped surface of the balance block. By arranging the balance block on the crankshaft, when the crankshaft rotates in high speed, the force balance is realized between one side of the eccentric shaft far away from the crank and the balance block, thereby avoiding the rocking of the crankshaft. The utility model has the advantages of simple structure, convenient installation and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of dieing machine, relates in particular to a kind of thrust balancing device of dieing machine bent axle.
Background technology
It is strong that high speed accurate numerical control press has whole rack construction rigidity, internal stress is little, the punching precision height, be fit to continuous punching production, can operate advantages such as the temperature position is little in 24 hours, be widely used in fields such as household electrical appliances, automobile, five metals, electronics, during the pressed sheet band, utilize high speed accurate numerical control press, lasting feeding along with the reciprocal high-speed motion and the blank of drift, the drift of this kind punch press and mould can strike out the shape that mould limits with the blank that is placed on the workbench, finish the punch forming work of continuous blank.Current high speed accurate numerical control press bent axle can produce and rock when rotating at a high speed.
The utility model content
The purpose of this utility model provides a kind of thrust balancing device of dieing machine bent axle, use this device can make eccentric shaft reach dynamic balance away from a side and the balance weight of crank, thereby bent axle is avoided rocking.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of thrust balancing device of dieing machine bent axle, comprise bent axle, the eccentric shaft that described bent axle comprises crank and is arranged on the crank outer surface, the outer surface of described crank also is provided with balance weight, it is one fan-shaped that the longitudinal section of described balance weight is, and described eccentric shaft is the most relative with the arcwall face of balance weight away from the sidewall of crank.
In the technique scheme, the longitudinal section of described balance weight is semicircle.
In the technique scheme, also be provided with two card arms on the described balance weight, be respectively arranged with screwed hole on these two the card arms, twist in the described screwed hole and be provided with bolt.
The utility model compared with prior art has following beneficial effect:
The utility model, can make eccentric shaft reach dynamic balance away from a side and the balance weight of crank, thereby avoid bent axle to rock when bent axle rotates at a high speed by balance weight is installed on bent axle.And the utility model is simple in structure, and is easy for installation, low cost of manufacture.
Description of drawings
Fig. 1 is installed on the structural representation of dieing machine for the utility model
Fig. 2 is a front view of the present utility model.
Fig. 3 is the utility model perspective view.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 3, a kind of thrust balancing device of dieing machine bent axle, comprise bent axle 1, described bent axle 1 is installed on the flywheel 5, the side of flywheel 5 is a clutch 7, the eccentric shaft 12 that described bent axle 1 comprises crank 10 and is arranged on crank 10 outer surfaces, the outer surface of described crank 10 also is provided with balance weight 3, and the longitudinal section of described balance weight 3 is semicircle.Described eccentric shaft 12 is the most relative with the arcwall face of balance weight 3 away from the sidewall of crank 10.Certainly the longitudinal section of balance weight 3 also might not become semicircle, can be other shape, such as its longitudinal section is and is slightly less than the fan-shaped of semicircle, or be slightly larger than the fan-shaped of semicircle, as long as bent axle 1 is when rotating at a high speed, balance weight 3 and eccentric shaft 12 reach dynamic balance away from a side of crank 10 and get final product.
Also be provided with two card arms 30 on the described balance weight 3, be respectively arranged with screwed hole 32 on these two the card arms 30, twist in the described screwed hole 32 and be provided with bolt (bolt is not shown).Be provided with card arm 30 and bolt, make that the installation of balance weight 3 is very convenient.
During installation, the arcwall face and the eccentric shaft 12 of balance weight 3 is installed on the bent axle 1 away from the opposed mode of the sidewall of crank 10, tights a bolt afterwards, two card arms 30 are drawn close, balance weight 3 is stuck on the bent axle 1 tightly.When bent axle 1 when rotating at a high speed, make eccentric shaft 12 reach dynamic balance away from a side and the balance weight 3 of crank 10.
