Abstract

The utility model relates to a material stop inductor for an automatic punching machine, which comprises a clamping seat, a roller, and a pressure bar, wherein, the clamping seat is supplied a material sheet for passing and arranged in the front of the punching machine; the roller and the pressure bar are arranged on the back of the clamping base. The utility model is characterized in that a support sheet is arranged along the back of the pressure bar; the support sheet is provided with two spaced parallel long slots; a higher sensing rod can be arranged in the first long slot, and a lower locating rod is arranged in the second long slot to make the back ends of the material sheet be pressed on the lower part of the locating rod when the material sheet is punched in an ordinary state; the punching machine is stopped by contacting the sensing rod when the tail end of the material sheet passes through the locating rod.

Description

Automatic punching machine stop expecting sensing apparatus

What the utility model related to a kind of automatic punching machine stops expecting sensing apparatus, is meant that especially it can be after tablet be sent to really, more exactly sensing and shutting down.

To the manufacturing of miniature parts, the most effectively and rapidly with the automatic high speed punch press.General this type of automatic punching machine is after startup, and what will place the punch press front end automatically sends constantly into punch forming between the mould at the rolling tablet.Therefore behind the materials and parts location, complete machine does not need artificial treatment with regard to constantly working automatically.Only dashed, just need use hand-stuff at materials and parts.In order to reach the purpose of automatic production, at punch press tablet end sensing apparatus can be set usually, make it send the back autostop at tablet, inform to reinstall another coiled strip sheet.

As shown in Figure 1, be the pay-off of general automatic punching machine, after it makes tablet 10 1 ends pass holder 11, send into the punching machine mold (end shows among the figure) in left side, expect that simultaneously body can pass through roller 12 and a depression bar 13.When tablet 10 approaching having sent, its tail end 14 will because it passes this sensing apparatus under no material state, start sensing apparatus and stop punch press and continue to move through one group of default sensing apparatus, and the staff just can carry out feed supplement.

Yet thisly stop expecting that sense mechanism do not consider the operating state of tablet 10 when punch forming.Be generally several meters long stretching situation with tablet, sending into the be stamped moulding or when thrusting (as shown in Figure 1), the tablet 15 at depression bar 13 rears can produce the situation of stressed shake of tablet between punching machine mold.Because this abnormal feeding shake will make itself and original transfer position break away from, therefore default sensing apparatus often is activated; thereby produce the false touch sensing apparatus; before having sent, material,, more do not increased staff's burden except making speed of production is obstructed with regard to self-stopping.

The purpose of this utility model provides a kind of automatic punching machine and stops expecting sensing apparatus, and this device can prevent false touch or the inaccurate shutdown action in the tablet punching course.

The utility model is achieved in that in the place ahead of punch press and is provided with for the holder that passes tablet; and the roller at this holder rear and depression bar; it is characterized in that: be provided with a supporting slice along the depression bar rear; this supporting slice is provided with two parallel elongated slots that separate; the sensory rod of a high bit can be set in first elongated slot; and a backstay than low level is set in second elongated slot; tablet is put below backstay by pressure the rear end when the normality punching press, shut down and touch sensory rod during by this backstay at its tail end.

Above-mentioned supporting slice is one of them sheet that is installed in depression bar.

Above-mentioned sensory rod and backstay all pass the supporting slice elongated slot with the end of thread, and wherein sensory rod is behind supporting slice front and rear surfaces installing insulating trip, locks and connects a conducting terminal with nut again, then directly locking behind sheathed pad of backstay.

Above-mentioned supporting slice can suitably extend, and installs another sensory rod additional at the opposite side of backstay.

The utility model is to be provided with a supporting slice at feeding depression bar rear; this supporting slice has two elongated slots that separate; make it assemble a sensory rod and a backstay respectively; put below backstay by pressure when allowing tablet rear end normality; and when materials and parts will give; can touch the sensory rod in the place ahead and accurately shutdown, prevent the false touch in the tablet punching course or inaccurately stop action.

Fig. 1 is the automatic punching machine pay-off figure that uses now.

Fig. 2 is the utility model embodiment stereogram.

Fig. 3 is the utility model embodiment element exploded view.

Fig. 4 is the utility model sensory rod assembled sectional view.

Fig. 5 is the side view of Fig. 2.

Fig. 6 is the side view of Fig. 5, shows that the conducting sensory rod is prepared to shut down.

Fig. 7 is that of the present utility model another implemented illustration.

Consult Fig. 2, the utility model pay-off includes equally for the holder 21 that passes tablet 90, and the

roller

22,23 and the depression bar 24 at these holder 21 rears, it is characterized in that: be provided with a supporting slice 30 along the depression bar rear, this supporting slice 30 is provided with two parallel elongated slots that separate 31,32, the sensory rod 50 of a high bit can be set in first elongated slot 31, and a backstay 70 than low level is set in second elongated slot 32.

Please consult Fig. 3, Fig. 4 simultaneously, the default end 51 that is spirally connected of sensory rod 50 is to pass first elongated slot 31, and after front and rear surfaces places felt

pad

52,53, a cover unification conducting terminal 54, and screwed togather fixing with nut 55.Backstay 70 then makes its end 71 that is spirally connected pass second elongated slot 32, and cooperates after the

pad

72,73 of front and back, is fixed with another nut 74.

As shown in Figure 5, when normality feeding punching press, tablet 90 is in regular turn by holder 21,

roller

22,23, depression bar 24 and be drawn into moulding between the diel.The rear end lamellar body of tablet 90 then is crushed on backstay 70 belows, makes itself and sensory rod 50 keep one section discontiguous gap, even tablet 90 under stressed dither state, and has just broken away from or do not touch sensory rod 50 by touching backstay 70.And when tablet 90 will send, as shown in Figure 6, its tail end will break away from backstay 70, and upwarp itself and sensory rod 50 crimping be conducted electricity, and punch press be shut down accurately carry out auxiliary material.

Because punching press tablet 90 has different-thickness and elastic force, so sensory rod 50 and backstay 70 be at the relative high and low position of first and second

elongated slot

31,32, locatees after can being adjusted at diverse location by unscrewing at any time of

nut

55,74, just can be suitable fully.

Consult Fig. 7, the supporting slice 300 of another embodiment of the present utility model also can extend, and assembles another sensory rod 501.Can prevent tablet 90 tail ends 901 like this when if unnatural warpage is arranged, can make that hook portion touches another sensory rod 501 and shutdown at once at this it on, prepare to reload.
