The specific embodiment

Like Fig. 1 and shown in Figure 4, a kind of automatic feeding that is applied to stamping machine comprises substrate 1, pushes module and blanking groove, and this propelling movement module is located on this substrate 1 along X-direction, and blanking groove is located on the substrate 1 along Z-direction.During use, the material base in the blanking groove enters into and pushes module, and by push module move to stamping machine 52 on process, accomplish the function of self-feeding.

Shown in Figure 1 is from the structural representation of pay-off under decomposing state, shown in pusher comprise a chute 21 and a master slider 22 and feeding cylinder 23.Chute 21 is arranged on the substrate 1 along X-direction, wherein is provided with the master slider 22 that can in this chute 21, move.Feeding cylinder 23 is located at an end of master slider 21, is used for promoting master slider 22 and moves at chute 21.

Blanking groove is " youngster " font, and its top hollow and be communicated with chute 21 is used to place material base; The bottom is fixed on the chute 21.Select excellent embodiment as a kind of, blanking groove comprises blanking gripper shoe 32 and is fixed on twice feed collets 31 on this blanking gripper shoe 32 that following feed collet 31 opposite sides are respectively equipped with groove, the convenient material base of placing.Blanking gripper shoe 32 is provided with a through hole, and the shape of through hole is corresponding with material base, and size can be slightly larger than material base makes material base from this through hole, to pass through.Blanking gripper shoe 32 crosswise fixed are on chute 21, and this through hole makes material base after the effect that relies on gravity falls from chute 21 over against chute 21, can fall among the chute 21 through the through hole on the blanking gripper shoe 32.

Positioner comprises a blanking push pedal 42 and a driver, and preferred, driver can adopt a blanking cylinder 41.Blanking push pedal 42 is located between blanking groove and the substrate 1, drives material base in the blanking push pedal 42 control blanking grooves through blanking cylinder 41 and can or can not enter among the chute 21.In order to reduce the displacement of blanking push pedal 42; Can in blanking push pedal 42, be provided with one with the identical through hole of blanking gripper shoe 32 shape of through holes, like this as long as blanking push pedal 42 a bit just can make material base through blanking push pedal 42 or can not be through among the blanking push pedal 42 entering chutes 21 with blanking gripper shoe 32 skew a little.

On die 52, also be provided with one comprise a nozzle jet module, nozzle is located on the die 52, is used for after the punch process that stamping machine 51 is accomplished material base, finished product being blown out die 52.

See also Fig. 4; In order to realize carrying out automatically feeding and processing; This pay-off also comprises a control module; This control module comprises a controller 60, sensor 61 and magnetic valve, thereby controller 60 is according to the signal controlling magnetic valve action control magnetic valve corresponding cylinder action of sensor 61.

Sensor 61 comprises blanking start sensor 614, detects the reset position of feeding sensor; Feeding start sensor 615 is used to detect the material base on the master slider 22; Feeding interlocking sensor 619 is used to detect the reset position of blanking push pedal 42; Pin system start sensor 616 is located on the said die 52, is used to detect the material base on the die 52; Pin system interlocking sensor 617 is used to detect the retrieving position of master slider 22; Air blowing sensor 612 detects the position that punch 51 is in punching press; Air blowing interlocking sensor 618 detects the position that punch 51 is regained; Air blowing stop sensor 613 detects master slider 22 and is positioned at the position of blowing and stopping; Expect quantity sensor 611, be used for detecting the material base amount of blanking groove, and feeding magnetic valve 621, be used to control feeding cylinder 23; Blanking magnetic valve 622 is used to control blanking cylinder 41 and pin system magnetic valve 623, is used for control pin system cylinder 53.

Below introduce the course of work of this pay-off:

Material base is deposited in the hollow space of blanking groove layer by layer.During normal the placement,, cause the material base in the blanking groove to proceed among the chute 21 through blanking push pedal 42 because blanking push pedal 42 slightly squints with through hole on the blanking gripper shoe 32.After the work beginning, blanking cylinder 41 promotes blanking push pedals 42 and moves, and the through hole in the blanking push pedal 42 is alignd with through hole on the blanking gripper shoe 32, and material base just can enter in the middle of the chute 21 like this.In case after having material base in the chute 21, blanking push pedal 42 homings can not get in the middle of the chute 21 material base again.

Subsequently, the master slider 22 that feeding cylinder 23 promotes in the chute 21 moves, and material base is pushed to the assigned address on the die 52.Material base on the die 52 behind the punch process finished product of punch 51, blown out die 52 by the nozzle on the die 52, accomplish the operation of punching press.

Course of action behind the employing automatic control module is following:

Feeding cylinder 23 is when initial position, and a baffle plate that is contained in the setting on the master slider 22 shelters from blanking start sensor 614, and blanking magnetic valve 622 is opened; Blanking cylinder 41 ejects material base and falls on the master slider 22, shelters from feeding start sensor 615 simultaneously, and starting feeding circuit also breaks off blanking magnetic valve 622 power supplys; Blanking cylinder 41 automatically resets and shelters from feeding interlocking sensor 619, and feeding magnetic valve 623 is opened the material base that feeding cylinder 23 will drop on the master slider 22 and sent in the mould, and shelters from pin system start sensor 616 simultaneously; Break off feeding magnetic valve 623 power supplys simultaneously; Feeding cylinder 23 resets, and when its return stroke sheltered from pin system interlocking sensor 617, punch press pin system magnetic valve 624 got electric opening; Pin system cylinder 53 draws back pin system, makes to be about to the material base moulding under the slider of punch.Also pick up simultaneously and block air blowing start sensor 612 and start the air blowing circuit with the interlocking sensor 618 of blowing, and the pin system of disconnection magnetic valve 624 power supplys, the pin system cylinder 53 pin system of making that resets is closed; After the material base moulding: after slider of punch is up to certain stroke, leave the interlocking sensor 618 of blowing, air blowing magnetic valve 621 is opened; Compressed air blows out the product of forming from mould, and keeps a period of time of blowing, and blanking begins next time simultaneously; After having descended material; Stop when master slider 22 slides into forward to blow when blocking air blowing stop sensor 613, process flow continues, so constantly back and forth work automatically; The material base that in time replenishes blanking groove when failing makes its folded height drop to deficiency and gives when sheltering from material quantity sensor 611, and automatic disconnection control power supply stops machine works.

With respect to prior art, this automatic feeding has greatly improved production efficiency through automation controller control, is particularly suitable for large-scale production; Secondly, the feeding action accurately because feeding starts and the gradual change design is all adopted in brake, can not receive effects of air pressure, saves material and reduces fraction defective.

More than describe the preferred embodiment of the utility model in detail, the ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the utility model design on the prior art basis through logic analysis, reasoning perhaps according to the available technical scheme of limited experiment, all should be among determined protection domain by these claims.
