Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the rotor punching cylindrical is located automatic blanking apparatus, and this device comprises upper bolster 2 and die shoe 9, and both adopt guide pillar 3 to connect, and upper bolster 2 can move up and down with die shoe 9 along guide pillar 3 and carry out clutch.
As shown in Figure 2, upper bolster 2 is tabular, and the surface has the chamber of caving in above that; Knockout plate 1 peripheral chamfering is embedded in the chamber of caving in; Stripper plate 13 is positioned at the below of upper bolster 2, and dnockout bolt one end is connected with stripper plate 13, and knockout plate 1 bottom that the other end passes in the upper bolster 2 and the chamber of caving in offsets; At the fixing pivot pin drift 17 of upper bolster bottom centre, the axis hole on the fixing flute profile drift 18 in upper bolster 2 bottoms of pivot pin drift 17 peripheries, the position of pivot pin drift 17 and flute profile drift 18 and the rotor punching of institute's stamping-out, the position of groove are corresponding.
As shown in Figure 2, for being convenient for changing pivot pin drift 17, flute profile drift 18, drift fixed head 15 is installed in the upper bolster bottom, pivot pin drift 17, flute profile drift 18 are connected with upper bolster 2 through drift fixed head 15.
As shown in Figure 2, on stripper plate 13, be provided with the through hole corresponding with pivot pin drift 17 and flute profile drift 18, stripper plate can slide up and down, and reaches to take off the material purpose.
As shown in Figure 2, on the dnockout bolt, be provided with adjusting pad 14, this adjusting pad 14 is a stereoplasm tube, mainly is the difference in height of adjustment stripper plate 13 and flute profile drift 18, pivot pin drift 17 bottom surfaces, to guarantee that stripper plate can take off material smoothly.
As shown in Figure 3; Die shoe 9 is tabular, and fixing circular counterdie backing plate 10 on die shoe 9 is installed circular counterdie 5 on the counterdie backing plate 10; Be provided with the pivot pin drift nib corresponding with the flute profile drift on the surface of circular counterdie 5, the waste channel 20 on nib and counterdie backing plate and the die shoe connects.
As shown in Figure 3, the corresponding nib periphery of flute profile drift on circular counterdie surface evenly is provided with some cylindrical locator protrusionss 6, adopts 6 pairs of rotor punching blanks of this cylindrical locator protrusions to carry out the cylindrical location, prevents displacement to occur at stamping-out process rotor punching blank.
This cylindrical locator protrusions 6 is at least 3, is centered around the periphery of the cylindrical of counterdie upper rotor part punching blank present position, and in the present embodiment, the number of cylindrical locator protrusions 6 is chosen as 4.
As shown in Figure 3; In twos material blocking rod 12 is installed between the cylindrical locator protrusions, the quantity of material blocking rod 12 is decided according to the quantity of cylindrical locator protrusions 6, in the present embodiment; Cylindrical locator protrusions 6 is 4; Material blocking rod 12 is also corresponding to be made as 4, and the spring 16 that material blocking rod 12 passes in the material blocking rod chamber in counterdie 5, counterdie backing plate 10 and the die shoe offsets, and material blocking rod 12 can slide up and down under the effect of spring.
As shown in Figure 3; Material blocking rod 12 slide up and down the control that is pushed away material blocking rod 8; An end that pushes away material blocking rod 8 passes the sidewall of counterdie backing plate, in pushing away the lumen that material blocking rod 8 passes the counterdie backing plate, is provided with steel ball 19, pushes away material blocking rod 8 and offsets through steel ball 19 and groove on the material blocking rod 12 bar walls.Its course of work is: when material blocking rod 12 is positioned at low level; Push away material blocking rod 8 and apply pretightning force through 19 pairs of material blocking rods 12 of steel ball; Material blocking rod 12 is locked, and steel ball 19 is not exerted pressure when pushing away material blocking rod 8, and material blocking rod 12 loses pretightning force and receives the promotion that spring 16 makes progress and move up.
Certainly the locking mode of in present embodiment, introducing, can also adopt other common locking modes of mechanical field.
As shown in Figure 3; Pushing away material blocking rod 8, when material blocking rod 12 to be applied pretightning force be that the linkage of the both sides through being distributed in the counterdie backing plate is controlled, and shown in figure, on die shoe, is provided with two connecting rod columns; The connecting rod column is provided with torsion spring 11; Two cover linkages are symmetrically distributed in the both sides of counterdie backing plate 10, and an end of two cover linkages is hinged with the connecting rod column respectively, and its other end is hinged jointly with the charging ram 4 that is arranged on the die shoe; Action through charging ram 4 promotes the linkage action; And push away an end of material blocking rod 8 and the connecting rod 7 on the linkage offsets, and the action through linkage realizes pushing away the turnover of material blocking rod 8 in the counterdie backing plate, thus influence applying and unloading to material blocking rod 12 pretightning forces.
This blanking apparatus is in when work, and stripper plate 13 is positioned at the bottom of flute profile drift 18, pivot pin drift 17 during stamping-out under the effect of adjusting pad 14 and dnockout bolt, material blocking rod 12 at torsion spring 11, connecting rod 7, push away under the pretightning force of material blocking rod 8 and steel ball 19 and be positioned at lower.This moment the mechanical feed hand feed, the rotor punching blank is positioned at hand face of feeding, the rotor punching bland position is higher than material blocking rod 12; The rotor punching blank is delivered to the counterdie center, and the front end of the hand of feeding simultaneously hits runs into charging ram 4,7 reaches of charging ram 4 drivening rods; Reduce pushing away the pretightning force of material blocking rod 8; Force to push away material blocking rod 8 and outwards move, material blocking rod 12 moves up under the promotion that spring 16 makes progress, and material blocking rod 12 is higher than the rotor punching blank.The backhaul of feeding hand, the rotor punching blank is accurately falling in cylindrical locator protrusions 06 under the stopping of material blocking rod 12, and slider of punch moves down; Material blocking rod 12 moves down in stripper plate 13 actions of gravity; End face and counterdie are with high, and slider of punch continues descending along guide pillar 3, move on stripper plate 13, adjusting pad 14, the knockout plate 1; Flute profile drift 18, pivot pin drift 17 cooperate with counterdie 5 accomplishes stamping-out, and blinking scrap gets into waste channel 20 by nib and drains.The slider of punch backhaul; The rotor punching that stamping-out finishes is up with drift, and Press Machine Stroke of Knock-Out impacts knockout plate 1, dnockout bolt, adjusting pad 14, drives the stripper plate 13 descending rotor punchings of taking off; Rotor punching drops on feeding hand end face, adsorber rotor punching blank when backhaul comes off rotor punching.This moment, material blocking rod 12 moved owing in the promotion of spring 16, and steel ball 19 just is against in the arc groove of material blocking rod 12 under the pretightning force of charging ram 8, connecting rod 7, torsion spring 11, makes material blocking rod 12 be positioned at lower.The feeding hand continues feeding, impacts charging ram 4 and repeats above action completion stamping-out.
