Description
Technical field
The utility model relates to the precise forging machine technical field, is eccentric sleeve type precise forging machine tup drafts adjusting device.
Background technology
Precise forging machine is a kind of forging machinery of realizing the radially synchronous forging method of many tups high frequency precision, when it forges, requires each tup to be synchronized with the movement, and high frequency forges, and its frequency can reach 180 ~ 2000 beats/mins.In the work engineering, the tup drafts of precise forging machine should can be adjusted according to the radial dimension that forges workpiece.The position of tup when this just requires its tup can adapt to different tup drafts.
Summary of the invention
The purpose of this utility model is to provide a kind of eccentric sleeve type precise forging machine tup drafts adjusting device, can realize fast, simply adjust the drafts of precise forging machine tup.
The technical solution of the utility model is eccentric sleeve type precise forging machine tup drafts adjusting device, which comprises at least drafts slide block, pull bar and eccentric bushing, and it is characterized in that: eccentric bushing is wedge shape, the pivot O of its broadside and frame
2Fixing, narrow edge tail O
3Place is fixedly connected with pull bar, and the front end of pull bar is provided with the drafts slide block, and the drafts slide block is driven by motor; Non-rotary central position O on frame
3Place also is provided with eccentric shaft, and the eccentric shaft lower end is provided with slide block, in slide block " a few font " chute on the connecting rod end face, slides, and the end of connecting rod is provided with tup.
The length of described eccentric bushing is greater than the radius of turn of frame, i.e. the pivot O of the broadside of eccentric bushing and frame
2Fixing, expose outside frame on narrow limit.
On described frame, chute is arranged, the drafts slide block is arranged in chute, and drives the along continuous straight runs motion by motor.
Characteristics of the present utility model are to drive the drafts slide block by motor, drive the eccentric bushing motion by pull bar, and then the eccentric shaft band movable slider at non-rotary central place is slided in the chute of connecting rod, thereby drive the motion of tup, reach the purpose of adjusting the tup position, package unit is simple, convenient, use, easy and simple to handle.
The accompanying drawing explanation
Below in conjunction with embodiment, the utility model is further described.
Fig. 1 is the structural representation of the utility model eccentric sleeve type precise forging machine tup drafts adjusting device;
Fig. 2 is the side view of the utility model eccentric sleeve type precise forging machine tup drafts adjusting device.
In figure: 1, frame; 2, drafts slide block; 3, pull bar; 4, eccentric bushing; 5, eccentric shaft; 6, slide block; 7, connecting rod; 8, tup; O
1, the eccentric shaft center; O
2, pivot; O
3, the pull bar fixed center.
The specific embodiment
As depicted in figs. 1 and 2, the pivot O of frame 1
2Place is fixed wtih eccentric bushing 4, and eccentric bushing 4 is wedge shape, and its broadside is at pivot O
2Place is fixing, outside narrow limit, is exposed at outside frame 1.
The narrow limit exposed parts O of eccentric bushing 4
3Place is fixedly connected with pull bar 3, and the front end of pull bar 3 is provided with drafts slide block 2.
Drafts slide block 2, in the chute of frame 1, is made front-rear reciprocation movement along horizontal direction, and drafts slide block 2 is to be driven by Electric Machine Control.
Non-rotary central O in frame 1
2Place is provided with eccentric shaft 5, and eccentric shaft 5 is positioned at O
1Place, when frame 1 rotation, eccentric shaft 5 will be with O
1For the center of circle circles.
The lower end of eccentric shaft 5 is fixed with slide block 6, and slide block 6 is arranged in " a few font " chute of connecting rod 7, and the end of connecting rod 7 is fixed with tup 8.
Reciprocating in eccentric shaft 5 rotary sliders 6 will " a few font " chute at connecting rod 7, thus the drafts that drives tup 8 changes.
During work, motor drives drafts slide block 2, drive eccentric bushing 4 motions by pull bar 3, and then the eccentric shaft 5 at non-rotary central place is slided in the chute of connecting rod 7 with movable slider 6, thereby drive the motion of tup 8, reach the purpose of adjusting tup 8 positions, package unit is simple, convenient, use, easy and simple to handle.
