The utility model compared with prior art, its remarkable advantage is that compacting is fused with demoulding leverage, is convenient to processing, guarantees precision.It is poor to have reduced the tired affair of bindiny mechanism's knot how.Adjust more convenient.Synchronism is good.Structure tube list.Regulate the size of charging quantity very easily, guaranteed product density and quality.Be used in the stampings of compacting difformity, thickness.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The specific embodiment
In conjunction with Fig. 1, Fig. 2, a kind of compacting of the present utility model and stripper apparatus comprise compacting cam 1, demoulding cam 2, roller 3, roller shaft 4, compacting fork 5, compacting backing plate 6, lever 10, fork axle 12, bearing 13, lever 10, worm and gear governor motion; One end of lever 10 is provided with the worm and gear governor motion, described worm and gear governor motion comprises and presses down screw rod 7, press down worm gear gland 8, worm bracket 9, limited block 18, worm screw 19, worm-wheel shaft 20, worm gear 21, worm-wheel shaft 20 is fixed on the worm bracket 9 and by worm screw 19 and is connected with worm gear 21, press down worm gear gland 8 and be arranged on the top of worm gear 21, control its shift position up and down, press down on the screw rod 7 gathering sill is set, limited block 18 is fixed on the top that presses down worm gear gland 8, described limited block is arranged in the gathering sill that presses down screw rod 7 and can moves up and down, thereby restriction presses down the rotation of screw rod 7, and guarantee that pressing down screw rod 7 moves up and down, pressing down screw rod 7 contacts with compacting backing plate 6, one end of compacting fork 5 is by fork axle 12, bearing 13 is connected with the middle part of lever 10, and can swing up and down, the other end of compacting fork 5 is equipped with roller 3 by roller shaft 4, described roller 3 is tangent with demoulding cam 2, under driving, it moves up and down, thereby drive presses down screw rod 7 and moves up and down, and described compacting backing plate 6 is connected on the compacting fork 5.
Stripper apparatus comprises demoulding cam 2, roller 3, roller shaft 4, lever 10, lever shaft 22.Because the compacting and the demoulding reset, and have adorned extension spring support, extension spring fixed axis and extension spring in the lever back lower place.Lever shaft 22 is arranged on the middle part of lever 10.
Since compacting and stripper apparatus they not at one time, and product suppress finish after the demoulding again, the utility model utilizes their time difference, original demoulding lever from new design, and is fused compacting and stripper apparatus, establish two supporting-points, a compacting, another is with regard to the demoulding.By the rotation of compacting cam and demoulding cam on the main shaft, thereby finish the work of suppressing failed part.
The utility model fuses compacting and demoulding leverage, suppress the rotation of cam 1 and demoulding cam 2 respectively by two cams above the driving shaft, drive two rollers 3, wherein a roller 3 presses down with the worm gear of installing below 21, worm screw 19 governor motions with roller shaft 4 drive compacting forks 5 and is connected.By compacting fork 5 following compacting backing plates 6, press down screw rod 7 by the 6 direct contacts of compacting backing plate, make screw rod pass through the worm gear rotating mechanism and realize down pressure stroke.Increase the process that subtracts down in (to the positive direction pressurization, to the negative direction decompression) and make assurance product density and quality.After regulating with worm bracket 9 screw-drivings.And look nut 11 lockings.
When suppressing adjusting, the rotation of worm shaft 20 drives worm gear 21, and the rotation of worm gear 21 drives screw rod 7, and screw rod 7 is moved up and down.Worm screw 20 0.17mm that whenever turns around.Regulate the size of charging quantity very easily.
The utility model is the important device in a kind of N series powder forming machine, product has utilized original demoulding lever and lever shaft in the shaping pressing process, add a supporting-point on demoulding lever, connect the compacting fork with a bearing pin, compacting and demoulding lever are fused.Structure comprises compacting cam, demoulding cam, roller, roller shaft, compacting fork, suppresses backing plate, presses down screw rod, presses down the worm gear gland, worm bracket, lever, hold-down nut, fork bearing pin, bearing, pressure-bearing pad, extension spring, extension spring fixed axis, extension spring support, limited block, worm screw, worm shaft, worm gear, lever shaft; Reduce bindiny mechanism, improved operating efficiency, reduced production cost.
