In addition, even opening and closing the deviation post ground, top of guide member 31, hypothesis inserts between pushing roller 25 guide surface that two inclined plane 31a of switching guide member 31 use as the position revisal, the capable revisal of automatic aligning offset shift-in in the interstice coverage of mold 1.Thus, when the pushing to of vertical tooth rack 18, can reliably vertical tooth rack 18 be inserted to the inner space 15b of rams 15.Consequently, although be simple structure, can realize the stable action of rack pinion formula drives structure body 16.
Afterwards, as shown in the solid arrow of Fig. 8, on the two inclined plane 31a that equate at angle of inclination by further decline ram 15, two pushing rollers 25, rotate, and two pushing rollers 25 centered by two rotating shafts 20 to evolution to rotating (Fig. 8).Thus, push lentamente switching function part 21,22 open.When two pushing rollers 25 rotate upward, the bottom of the upper end butt ram 15 of baffle plate 24, so its maximum rotation angle is limited.
And, when the opening of switching function part 21,22 (angle) surpasses the width of vertical tooth rack 18 (Fig. 9), by the elastic force of two helical springs 32, push to vertical tooth rack 18 and retract rapidly horizontal rack 28 and chute 7 (Figure 10).Consequently, vertical tooth rack 18 is incorporated in the inner space 15b of ram 15 through opening 15a.Now, buffer stopper material 46 is with the side of the state collision shell 27 of face contact.Thus, a pair of helical spring situation that becomes line contact condition in the past with use is compared, and acts on the impulsive force diffusion of the side of shell 27, consequently, can fully relax the impulsive force from this chute 7.And, while being brought to this mode vertical tooth rack 18, the upper end of vertical tooth rack 18 is arranged on the top on the mountain top that opens and closes guide member 31.
In this mode, be accompanied by raw-material punch process at this, when mold 1 drops to assigned address, rack pinion formula drives structure body 16 drives chute 7, and makes chute 7 back and forth movement in generally horizontal plane.That is, chute 7 is past moving to a direction with the speed of appointment, and if after stopping, returning round about.When chute 7 stops, the power of appointment acts on workpiece 3a or waste material 3b because of the action of chute 7.This force rate and the above-mentioned power that acts on workpiece 3a etc. because of the friction of effect between workpiece 3a or waste material 3b and chute 7 are that rightabout power is larger.Consequently, workpiece 3a or waste material 3b are expelled to the outside of stamping machine B from chute 7.
In addition herein, the vertical back and forth movement of the mold 1 as by punch process the time is transformed to the mechanism of the horizontal back and forth movement of chute 7, owing to having adopted rack-and pinion gear mechanism, so workpiece 3a or the discharging operation of waste material 3b from chute 7 become smooth and easy, the durability of device improves, and can with higher power transmission efficiency from mold 1 to chute 7 transferring power.
And, horizontal guide structure section 51 as the vertical guide structural portion 50 of the vertical tooth rack 18 of a part that forms rack pinion formula drives structure body 16 and horizontal rack 28, having deleted respectively in product in the past is the sliding eye formed in two tooth bars 18,28 of necessary inscape, and has adopted a pair of vertical structure of usining as the deflector roll of tooth bar slip use with cylinder sleeve pipe 37B by cylinder sleeve pipe 37A and a pair of level had with the another side section butt that is opposition side with one side section with tooth 38 each tooth bar 18,28.Consequently, can maintain the back and forth movement smoothly of vertical tooth rack 18 and horizontal rack 28, and improve the intensity of two tooth bars 18,28, and the impulsive force produced while the being suppressed at device action vertical tooth rack 18 that is reason and the distortion of horizontal rack 28.
Afterwards, as shown in the dotted arrow of Fig. 8 and Fig. 9, be accompanied by the rising of mold 1, two pushing rollers 25 of switching function part 21,22 rotate in the two sides of vertical tooth rack 18, and ram 15 risings (returning) (Fig. 8 and Fig. 9).And, in the time of above two pushing rollers 25 arrival vertical tooth racks 18, two switching function parts 21,22 rotate downwards centered by roll shaft 26 because of deadweight, and again close switching function part 21,22 (Fig. 6 and Fig. 7).Now, because corresponding pushing roller 25 is arranged on the medial side of the width of ram 15, so two switching function parts 21,22 center of gravity separately is partial to the medial side of the width of ram 15.Therefore, at switching function part the 21, the 22nd, while closing state, the outer peripheral face of two pushing rollers 25 becomes the line contact condition.
