Description

ca. G. GREULICH Filed June 26, 1936 Patented June 8, 1937 UNITED STATES" PATENT OFFICE 2,083,320 AUTOMATIC no'rAnY PUNCH Gerald G. Greulich, Mount Lebanon, Pa. Application June as, 1936, Serial No. 87,553 Claims. (01. 164 -99) Other objects and advantages will become apparent as the description proceeds, in which: 15 I Figure 1 is a front elevation showing the cooperative relation of the die members,
Figure 2 is a transverse section, partly in elevation, of the die members and driving mechanism, and
20 Figure 3 is an enlarged detailed section of the die members and plunger operating means.
In the drawing, 2 and 3 represent male and female die members, each carried by and rotating with intermeshing gear wheels 4 and 5 which may be driven in synchronism by any desired 25 type of driving means, notshown.
The male die member 2, which is secured to p the gear wheel 4 in" any conventional manner, as shown at B in the drawing, comprises a steel 30 ring'l, provided on the outer peripherial body portion thereof with a plurality of spaced openings 8 through which spring actuated plungers, or cutting members 9, pass to punch the metal irom the sheet stock. The inner peripherial por- 35 tion of the ring I is provided with enlarged recesses l2 for receiving the enlarged head 93 of the plungers 9 and the spring it which encircles the body portion of said plungers.
The enlarged heads l3, of the plungers 9, are 40 provided with a curved portion l5 forming a. cam surface and an opening through which pins l6 project to engage a retracting cam lever l! to eflect rapid retraction of the plungers 8' should they become wedged or stuck in the open- 45 ings 8 and fail to be returned to their retracted position by the springs M. The cam surface IE or the plungers 9 projects beyond the inner periphery of the ring I and is engaged upon the said surface by a roller or member is which is 50 mounted on the free end of a lateral extension 59 or a non-rotatable shaft 20. This shaft 20 extends through the bore of the gear wheel 4 which is driven to rotate the steel ring I.
The female die member 3, which is secured to 55 the gear wheel 5 in any conventional manner similar to the construction shown at 6, comprises a steel ring 2| provided on its periphery with. suitable openings 22 coinciding with the openings 8 or the male die membe at the point of contact with the material to be punched, to 5 permit the plungers 9 to pierce the metal and project slightly into the recess in ring 2| whereby the punched metal will drop out through the bottom of the opening 22.
The metal to be stamped or punched out is 10 fed, in the direction of the arrow shown in the drawing, to pass between the two die members, each of which is rotating in synchronism, and as the die ring 2 rotates, it successively brings the cam surface l5 of plungers 9 into contact with 16 the roller l8 to produce a cam action on the race of the plungers 9 and depress said plunger-s into contact with the work, which pierces or stamps out the metal from the material permitting the cut out portion to fall through the 20 opening 22 and the punched material remain flat and pass on to suitable means for collecting the punched sheet. In order to facilitate production, it is proposed to have the die members 2 and 3 contact the material being punched 25 with suflicient pressure so as to feed or draw the material continuously through the machine. Any suitable means may be provided for maintaining pressure of the die rings upon the material being punched.
While the springs I4 under the enlarged heads 13 of the plungers 9 would ordinarily retract said plungers as soon'as they are free from contact with the roller member I8, they might tend to stick; however, to insure that the plungers will not stick, a retracting cam finger ll engages having a cam shaped upper surface which the under side of the pin l6 projecting from the head 13 of the plungers d, thus making certain rapid retraction of said punches. 40
It, therefore, becomes apparent that the present invention provides a machine which will punch holes rapidly and clean without excessive wear on any one punch due to the multiplicity of punches around the periphery of the die member 2 and permit the material to fall through openings in the female die member while the material, which has been punched, will pass on through the die members in a substantially flat condition. l
