Application in the modern forging and stamping production of the industries such as automobile, aviation, petroleum machinery is increasingly extensive, is that modern forging production is indispensable
High precision apparatus.And eccentric shaft is the important spare part of hotdie forging press, its center is not at the center of axis, generally
Axis, can only drive workpiece rotation, but eccentric shaft, can not only transmit rotation, while revolution can also be transmitted.The structure of eccentric shaft
Feature is that have two parallel and misaligned axis.
Currently on the market, the eccentric shaft of hotdie forging press, as shown in Fig. 2, including main body 1,, in main body 1,Upper edge master
Body direction of axis line integral type eccentric setting has a line eccentric body shaft 2,, the main body 1,Leading portion is sequentially coaxially set as by left and right
11,, First Transition section 12,, the second changeover portion 13,With back segment 14,, leading portion 11,Diameter and back segment 14,Diameter it is equal, first
Changeover portion 12,Diameter and the second changeover portion 13,Diameter it is equal, First Transition section 12,Diameter be more than leading portion 11,Diameter,
And eccentric body shaft 2,It is arranged on First Transition section 12,With the second changeover portion 13,Between.Eccentric shaft band movable slider with this configuration
When carrying out pushing workpiece, can inevitably be deformed with larger stress, this has an impact the precision of workpiece.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model provides a kind of pressure of hot die forging eccentric drive shaft.
The utility model includes shaft body, has one in the shaft body upper edge main body direction of axis line integral type eccentric setting
Row eccentric body shaft, the axial line of the shaft body, the axial line of eccentric body shaft are arranged in parallel, and the eccentric body shaft is divided to two sections
Setting, the eccentric body shaft is symmetricly set on the both sides of the shaft body interlude, in shaft body centre position and eccentric body shaft
The axis surface upper limit position block of opposite side.
The utility model connects forging press by setting two sections of symmetrically arranged eccentric body shafts between two sections of eccentric body shafts
Other component by setting limited block that can reduce the stress and amount of deflection of the hotdie forging press course of work, and then improves workpiece
Machining accuracy.
Shaft body described in the utility model is once coaxially disposed by left and right as leading portion, First Transition section, interlude, second
Changeover portion, back segment, the diameter of leading portion is equal with the diameter of back segment, the diameter of First Transition section and the diameter of interlude and the second mistake
The diameter for crossing section is equal, and the diameter of First Transition section is more than the diameter of leading portion；One eccentric body shaft is arranged on First Transition section
Between interlude, another eccentric body shaft is arranged between the second changeover portion and interlude, and the diameter of eccentric body shaft is more than the
The diameter of two changeover portions, the upper surface of interlude set the limited block.
The pressure of hot die forging eccentric drive shaft of the utility model, will be in main body compared with existing pressure of hot die forging eccentric drive shaft
The lower face of centre of eccentric body shaft be set as a recess, make the axial line of the interlude of eccentric body shaft and the axial line of shaft body
It overlaps, forms two sections of eccentric body shafts, eccentric body shaft becomes two points stress from more original stress, and stress differentiation reduces
Generate the probability of deformation.
The utility model shaft body is formed by turnery processing, leading portion, First Transition section, interlude, the second changeover portion,
Back segment and eccentric body shaft are integrated setting.
