In Fig. 4, with the rotation of sprocket wheel 46, it is 133 ° that first axle 44A and second axis 45A were formed, which is angle,.
First bar 27A is leaned against on the feeding slot 43 of each feeding claw 42.In total load path, from accumulator 24 to work work
When making on platform 22, first bar 27A is constantly under the maximum support of feeding slot 43, and bar movement is driven in feeding claw 42
In the process, bar is without departing from feeding claw 42.
It needs exist for reminding, accumulator 24 and workbench 22 are equipped with slot, and claw is allowed to have free passage.
When the feeding angle of bar is 60 °, feeding claw 42 is lifted up the first bar 27A, in next movement
In, the upper end bar 27 of neighbouring first bar 27A will scroll down through under the effect of gravity, but its still with first bar 27A
Between there are pressure, i.e., always exist contact line 28 between the two.For purposes of illustration only, in from Fig. 2 to Fig. 4, feeding claw 42 is grabbed
A bar is lived, upper end bar 27 gradually reduces, and entire movement continues, in itself gravity and the thrust of bar below
Lower bar 27B is moved down.
As shown in figure 5, the continuation of first connecting rod 44 is what negative direction rotation, first axle 44A and second axis 45A were formed
Angle is 195 °.In movement from 133 ° to 195 °, the contact line 28 of upper end bar 27 and first bar 27A are gradually put down
Steady is transitioned on the rear side edge 42A of feeding claw 42.
Similar mode, as first connecting rod 44 drives the rotation of support plate 41 and feeding claw 42, upper end bar 27 right
The contact line 28 of side 42A is pass by, and is smoothly transitioned on the shoulder block 24A of accumulator 24.
In figure 6, as first connecting rod 44 continues rotary motion, feeding claw 42 is begun to decline, at this time first axle 44A
What is formed with second axis 45A be angle is 315 °.The content shown according to Fig. 6, first bar 27A have been lowered into work
Platform 22, at this point, feeding claw 42 is by the slot on workbench 22, and bar stays on workbench 22, completes the load of bar.
Under this load mode, existing equipment two at impact, i.e., follow-up bar transported bar by feeding claw 42
The impact to the shoulder block 24A of accumulator 24 and bar fall the impact on workbench 22 later, are completely avoidable.
In fig. 2 it can be seen that (0 °/360 °), long stroke propulsion die 70 is in lower position, and in the (positions Fig. 3 to Fig. 6
60 ° to 315 °), long stroke propulsion die 70 maintains a high position.Third connecting rod 62 can be rotated around the 4th shaft 64, in spring 65
Under the action of rest on second baffle 67A, and second connecting rod 61 rotates around the 4th shaft 64, and passes through third shaft 51

Module 70 is linked by linkage 60 and feeding device 40, while action and the long stroke of the first connecting rod 44 of feeding device 40
Propulsion device 70 enters the action of a high position from a low position, be combined with each other.
It should supplement, the action of feeding device 40, this can lead to the action of linkage 60, wherein first rotating shaft
45 and the 4th the position of shaft 64 be fixed, and the position of the second shaft 49 and third shaft 51 is transportable.
The unique distinction of feeding device 40 is that it loads bar and will not generate impact to feed device.
Fig. 7 shows the centrode of first bar 27, describes the process that workbench 22 is loaded onto from accumulator 24.
More precisely, about Stowage Plane 7, this curve is from the 1: 56 (center of bar 27, when it is parked in accumulator
When on 24 shoulder block 24A) start, it is (identical when it is parked on workbench 22 in second point 55 according to the arrow in negative direction
The center of bar) complete its movement.Curve illustrates feeding claw from 1: 56 to second point 55 sections (always in negative direction)
42 catch the bar on accumulator 24 bar to be put into feeding claw 42 all centre positions on efforts platform 22.
In bar loading procedure, every speed is not necessarily uniformly on the path curves 58 that bar generates.
In fact, it can easily be programmed by such a mode, it is opposite in second point 55 and the 1: 56 areas adjacent
Slowly, the path for leaving these regions is relatively quick.
In addition, the axis at the center by workbench 22, should be located on the axis of lathe spindle.It is observed that adding
When carrying a bar, efforts platform 22 is no motion of.
