lA/VE/VTO/P JOSEPH 7: PICK/1R0 ATTORNEY .EIIII June 7, 1966 J. T. PICKARD STRIP EDGE FINISHING MACHINE 2 Sheets-Sheet 2 Filed Jan. 4, 1965 United States Patent 3,254,568 STRIP EDGE FINISHING MACHINE Joseph T. Pickard, River-ton, N.J., assignor to Joseph Pickards Sons (10., Philadelphia, Pa., a corporation of Pennsylvania Filed Jan. 4, 1965, Ser. No. 423,270 10 Claims. (Cl. 90-24) This invention relates to strip edge finishing machines and more particularly to machines for providing the desired finished edge contour or shape on metal strips of indefinite length.

The present practice in forming metal strips is to cut the strip from wide material and then move the material lengthwise between-files, rolls or gangs of tools disposed to give the edge contours desired, a plurality of passes usually being required. No wholly satisfactory apparatus for continuous and rapid finishing of the edges of metal strips is now available.

It is the principal object of the present invention to provide a machine for quickly and smoothly finishing the edges of strip material to provide the desired shape thereof, including rounded, beveled, angled or flat.

It is a further object of the present invention to provide a strip edge finishing machine which is simple in construction, sturdy, readily adapted for change to the desired edge shape for the strip of any desired width or gage, and with which precision shaping can be efiected.

It is a further object of the present invention to provide a strip edge finishing machine in which the strip to be finished is continuously advanced between spaced cutters on opposite edges 7 thereof, the cutters having abutments in opposed relation thereto and the cutters and abutments being relatively laterally adjustable for precision finishing.

It is a further object of the present invention to provide a strip edge finishing machine for metal strips in which the strip material is advanced under tension to 'facilitate the edge finishing.

Other objects and advantageous features of the invention wil be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part thereof, in which:

ture disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several 7 views.

Referring now more particularly to the drawings the machine in accordance with the invention preferably inice cludes an elongated frame 10 with a horizontal bed plate 11 and having therebeyond at one end .a driving or take-up roll 12 supported on and secured to a shaft 13, the shaft 13 being driven in any desired manner such as by an electric motor 14. The bed plate 11 has therebeyond at the opposite end thereof a supply roll 15 for the strip material 16, the edge of which is, to be finished. The roll 15 is supported on and secured to a shaft 17. The shaft 17 can be driven in any desired manner, by being coupled to the shaft 13, or by its own electric motor 18. The shaft 13 and 17 are actuated so that the peripheral 'or linear speedof the strip 16 arriving at the roll .12 is slightly greater than the peripheral or linear speed of the strip 16 leaving the supply roll 15, to maintain the strip 16 under tension during its :advance.

The bed plate 11 has carried thereon, on a mounting block 20, a pair of spaced horizontal guide rollers 21 for enaga'gement by the edge of the strip 16. The rollers are journaled on vertical shafts 22.

An adjustable block 23 has spaced horizontal guide rollers 24 carried on vertical shafts 25, the block 23 being held against the strip 16 by the engagement thereagainst,

of an adjusting screw 26 which extends through a vertical upright bar 27 secured to the block mounting 20.

The bed plate 11, beyond the block mounting 20, has a first edge cutter and abutment assembly 30 which includes transverse frame blocks 31 secured to the bed plate 11 in any desired manner such as by screws 32.

The frame blocks 31 have secured thereto an elongated longitudinally disposed roller carrying plate 33. The plate 33 has a plurality of vertically disposed flanged abutment rollers 34 held by snap rings 35 and supported on horizontal shafts 36. The rollers 34 (see FIG. 7) have cylindrical faces 37 for engagement with horizontal portions of the strip 16 and disc faces 38 for engagement with vertical edge portions of the strip 16.

The shafts 36 are preferably removably held by set screws' 39 in the plate 33 for replacement by other sizes of rollers 34 if required for a different size of strip.

While the rollers 34 can be arranged as desired it is preferred that two rollers 34 be disposed above and one roller 34 be disposed Ibelow the strip 16.

The rollers 34 (see FIG. 7) are preferably backed up by roller thrust bearings 40 carried between inner and outer rings 41 and 42 and engaging back-up spacer rollers 43.

The cutter assemblyv 30 has a fixed transverse guide plate 45 held on the bed plate 11, with an adjustable mounting plate 46 slidably carried on the guide plate 45 such as by a dovetail 47. The mounting plate 46 is positioned by a screw 48, rotatable by a hand wheel 49, the screw 48 having an' indexing head 50 and engaged in a nut (not shown) in the plate 46 rearwardly of a fixed sleeve 51 carried by an upright bar 52 on the bed plate 11. The sleeve 51 preferably has a scale 53 thereon for comparison with the indexing head 50.

The mounting plate 46 has a recess 55 within which a cutting tool 56 is inserted. The tool 56 is held against vertical movement by a clamping plate 57 and bolts 58 and is horizontally transversely adjusted #by an adjusting screw 59.

The cutting tool 56 is preferably of ultra hard material such as tungsten carbide and has a cutting contour 60 complemental to the edge shape-desired on the strip 16. The cutting tool 56 can have a face 61 providing back rake and a face 62 providing relief.

The bed plate 11, beyond the first edge cutter and abutment assembly 30, .has a second edge cutter and abutment assembly 65, which includes transverse frame blocks 131 secured to the bed plate 11 in any desired manner such as by set screws 32.

The frame blocks 131 have secured thereto an elongated longitudinally disposed cutting tool carrying plate 133. The plate 133 has a recess 155 within which a cutting tool 156 is inserted. The tool 156 is identical to or similar to the tool 56, dependent upon the edge shape desired and is held against vertical movement by a clamping plate 157 and bolts 158 and is horizontally transversely adjusted by an adjusting screw 159.

An elongated roller carrying plate 133 is provided having a plurality of vertically disposed abutment rollers 134, identical to the rollers 34, held by snap rings 35 and supported on horizontal shafts 136. The rollers 134 have faces 37 and faces 38 as previously described. The shafts 136 are held by set screws 139 in the plate 133 for replacement by other sizes of rollers 134 if desired. The rollers 134 are backed up by thrust bearing 40 carried between inner and outer rings 41 and 42.

The plate 133 is secured to an adjustable mounting plate 146 similar to the mounting plate 46 which is slidably carried on a guide plate 145 by a dovetail 147. The mounting plate 146 is positioned Iby a screw 148 rotatable by a hand wheel 149. The screw 148 has an indexing head 150 and is engaged in a nut (not shown) in the plate 146 rearwardly of a fixed sleeve 151 carried by an upright bar 152 on the bed plate 11. The sleeve 151 has a scale 153 for comparison with the indexing head 150.

In FIG. 8, a plurality of metal strips with their edges finished are shown in transverse cross section. The strip 16 is formed with rounded edges by the use of cutting tools 56 as shown in FIG. 3 on each edge. The strips 16a and 16b are formed with flat edges formed by flat edged cutting tools with their cutting edges disposed at the proper angles to provide such edges. The strip 160 is formed by a cutting tool having a V-shaped notch of the proper complemental shape. The strip 16d is formed by a recessed cutting tool having a fiat cutting edge portion to provide a square edge.

The bed plate 11 can also have a horizontal hold down roller 66 rotatably carried by a mounting block 67 secured to the bed plate 11 by bolts 68.

Each of the cutting tools can have cutting fluid delivered thereto in any desired manner to facilitate the edge cutting with cooling and chip removal.

The mode of operation will now be pointed out.

A strip 16 with raw or unfinished edges is supplied from the supply roll 15, and passes between the pairs of rollers 21 and 24 which reduce any tendency to sidewise displacement. The strip 16 with one raw edge engaging the faces 38 of the abutment rollers 34 and held against vertical movement by the cylindrical faces 37 of the rollers 34 has the other raw edge cut by the cutting tool 56 to the desired finished shape and contour so that no further finishing of that edge is necessary.

As the strip 16 advances the finished edge thereof engages the 'faces 138 of the rollers 134 which hold the other or unfinished edge for cutting by the cutting tool 156.

The cutting tool 56 in its spacing from the abutment rollers 34, and the abutment rollers 134 in their spacing from the cutting tool 156 can be quickly and easily adjusted by movement of the hand wheels 49 and 149.

As the strip 16 advances it passes under the hold-down roller 66 and to the driving roll 12. As previously pointed out the strip 16 between the roller 15 and 12 is maintained under tension by the differential speed of those rolls.

As illustrative, one type of strip can be of a width of three-quarter of an inch and of a thickness in the range from 0.025 inch to 0.125 inch. Speeds of strip movement of the order of four hundred feet per minute and higher can be attained with carbon steel. These illustrations are merely by way of example as other thickness and widths of strip material can also have finished edges applied thereto.

It will thus be seen that simple but effective apparatus is provided for effecting the objects of the invention.
