Describe the course of action of present technique scheme in detail with first kind of controlling organization.
State towards preceding equipment is down, and is as depicted in figs. 1 and 2, and first tumbler 12 and second tumbler 13 are pushed down the sidewall of locating part 11 simultaneously, and switch shaft 8 receives tension spring 15 pullings and its otch 81 is kept over against slide block passage 5.When driving adjusting connecting rod 2 promotion slide blocks 3, press crankshaft moves downward; First tumbler 12 and second tumbler 13 on the switch shaft 8 slides along the sliding trajectory on each comfortable locating part 11 sidewall at this moment; Secondary slide block 6 on the slide block 3 relies on the elastic force of first back-moving spring 7 and keeps and being synchronized with the movement of slide block 3 with the frictional force of secondary slide block 6, before the load mould 4 of this state on secondary slide block 6 arrives workpiece.When load mould 4 will arrive workpiece on the secondary slide block 6, though first tumbler 12 has been crossed locating part 11 bottoms, because of second tumbler 13 still slides 16 1 sections of the corners of its corresponding sliding trajectory 18; So first tumbler 12 still can not rotate towards the direction of locating part 11,, treat that slide block 3 continues to lower slider like Fig. 3 and shown in Figure 4; The load mould arrives workpiece, and the slip end face top 131 of second tumbler 13 is through a moment of corners 16 cusps, and second tumbler 13 will rotate towards locating part 11 moment; First tumbler 12 rotates with second tumbler 13 because of the restriction that loses second tumbler 13 simultaneously; At this moment switch shaft 8 rotated with 12 moments of first tumbler, and otch 81 rotating certain angle of switch shaft 8 make it can be over against slide block passage 5; Like Fig. 5 and shown in Figure 6; The roll body of switch shaft 8 is pushed down secondary slide block 6, and like this, slide block 3, secondary slide block 6 and load mould 4 are just realized being rigidly connected; Operating pressure by slide block 3 through switch shaft 8, secondary slide block 6, load mould 4 to the workpiece punching press until bottom dead centre, reach work acting requirement.After bottom dead center slide block 3 drives secondary slide block 6 backhauls; Like Fig. 7 and shown in Figure 8; In the incipient stage of backhaul, corners 16 and its bottom angled face 19 of locating part 11 order about corresponding second tumbler 13 and first tumbler, 12 backward rotation respectively, push down locating part 11 sidewalls again simultaneously up to two tumblers; In first tumbler, 12 counter-rotational switch shaft 8 backward rotation that drive simultaneously; The otch 81 of switch shaft 8 is gone to again over against slide block passage 5, until top dead-centre, prepares the next impulse stroke of continuity.
And situation appears: slide block 3 by top dead centre when bottom dead centre moves; When load mould 4 is run into foreign material or the staff on workpiece; Because switch shaft otch 81 is over against slide block 3 passages, load mould 4 has guaranteed load mould 4 and people's safety because of secondary slide block 6 indentation passages 5 stop to press down.Because this period switch shaft 8 is in released state with secondary slide block 6, load mould 4 does not receive the operating pressure of slide block 3, has only the inertia force of a spot of spring force and secondary slide block 6 and load mould 4, as long as reasonable in designly just can not damage.And when secondary slide block 6 was prevented from moving downward, slide block 3 still continued to move downward, and secondary slide block 6 just shrinks in slide block 3 by the parallel sliding direction; And switch shaft 8 moves downward to controlling locating part 11 triggering conversions during the period with slide block 3, because the top of secondary slide block 6 has slipped over the otch 81 of switch shaft 8, makes switch shaft 8 lose the space of rotation; So switch shaft 8 can't rotate; Slide block 3, switch shaft 8 and secondary slide block 6 can not form and be rigidly connected, and only keep former released state, arrive after bottom dead center until slide block 3; Return back to top dead-centre and prepare next workflow, thereby reach the safeguard protection effect of operation.In the ordinary course of things, on the secondary slide block 6 load mould 4 before arriving workpiece, industrial accident ninety percent injury is from this segment distance at top dead-centre; Because this segment distance is the loading and unloading periods, the space is maximum between the mould up and down, and run duration is long; Foreign material and staff are strayed into the most easily, and the direction of motion is a diminishing process in space, and this causes condition for injury; Therefore, protect this period safety, just can prevent most of security incident.As for the process of load mould 4 arrival workpiece place's punching press to bottom dead centres, because run duration is short, also be a closed space, seldom cause injury to the people, make progress away as for backhaul stage load mould 4, between mould, do not constitute injury.The safety protective device is applicable to that personnel selection hand operated person such as punching press and the riveted part of baby press uses.
Describe the course of action of present technique scheme in detail with second kind of controlling organization.
Before the punching press, the state of equipment is that the otch 81 of switch shaft 8 is in over against slide block passage 5, breaks through journey under making with this; When load mould 4 runs into barrier, can provide secondary slide block 6 slidably retractable space, drive load mould 4 shrinks in passage 5, avoids accident to take place; When slide block 3 glided together with travel switch 25 and touches the stroke dog 26 on the end of slide block 3 sliding traces below, the signal of telecommunication started tractive magnet 21 energisings, and its movable block 23 is withdrawn by adhesive; 22 swings of pulling swing arm, swing arm 22 drives switch shaft 8 and rotates, and it is non-over against slide block passage 5 that switch shaft otch 81 is turned to; Causes switch beaming roller body is pushed down secondary slide block 6, makes slide block 3, secondary slide block 6 and load mould 4 realize being rigidly connected, and slide block 3 dashes under doing further; Workpiece is carried out press work,, and reach before stamped workpieces up to bottom dead centre; Slide block 3, secondary slide block 6 and load mould 4 all are in released state, promptly are not in to be rigidly connected, and play protection operator's purpose.During backhaul, slide block 3 upwards slides, and stroke dog 26 leaves the arm of travel switch 25, and the signal of telecommunication interrupts; Tractive magnet 21 outages, under the effect of second back-moving spring 24, swing arm 22 backswings, switch shaft 8 backward rotation; Drive movable block 23 and stretch out, switch shaft otch 81 makes slide block 3, secondary slide block 6 and load mould 4 be in released state once more again over against slide block passage 5 simultaneously; Promptly be not in and be rigidly connected,, prepare the next impulse stroke of continuity up to returning top dead-centre.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
