Mechanical press, especially a cupping press

Claim 2

In a mechanical press; a press frame having a crown and a bed and uprights extending between the crown and head, an outer slide, first means including cooperating elements of gib means on said uprights and the corners of side outer slide for guiding said outer slide on said uprights for movement toward and away from the bed, said elements of gib means having two interengaged angularly related surfaces perpendicular to each other on a single member at each corner of the outer slide and said elements of gib means being relatively adjustable, an inner slide, second means guiding said inner slide in said outer slide for movement parallel to the movement of the outer slide, a crankshaft rotatable in the crown, a respective pair of throws on the crankshaft for each slide, and a respective pair of connecting rods for each slide, each connecting rod having one end pivotally connected to the respective slide and the other end engaging a pertaining throw of the crankshaft, means for adjusting the effective location of the die mounting surface of the slide with respect to the location of the lower end of the connecting rods, the said throws pertaining to one of said slides being angularly offset from the throws pertaining to the other whereby upon rotation of said crankshaft one of said slides will lead the other thereof in both directions of movement of the slides.

Claim 3

A mechanical press according to claim 1 in which the throws pertaining to the outer slide are offset forwardly from the throws pertaining to the inner slide whereby the outer slide leads the inner slide.

Claim 4

A mechanical press according to claim 1 in which said second means comprises cooperating elements of gib means on the corners of said inner slide and in said outer slide, said elements of gib means having interengaged surfaces, said elements of gib means on one side of the inner slide having the interengaged surfaces thereof parallel to a first plane and said elements of gib means on the opposite side of the inner slide having the interengaged surfaces thereof in respective second planes which are disposed at an angle to said first plane and to each other.

Claim 5

A mechanical press according to claim 3 in which each said second plane makes an angle of about 45* with the first plane, said second planes being substantially perpendicular to each other and converging in a direction away from the respective side of the inner slide.

Claim 6

A mechanical press according to claim 3 in which said elements of gib means for said inner slide includes elements adjustably mounted in said outer slide, and means adjustably securing the elements in said outer slide and accessible from the outside of said outer slide.

Claim 7

In a mechanical press; a press frame having a crown and a bed and uprights extending between the crown and bed, an outer slide, first means guiding said outer slide on said uprights for movement toward and away from the bed, an inner slide, second means guiding said inner slide in said outer slide for movement parallel to the movement of the outer slide, a crankshaft rotatable in the crown, a respective pair of throws on the crankshaft for each slide, and a respective pair of connecting rods for each slide, each connecting rod having one end pivotally connected to the respective slide and the other end engaging a pertaining throw of the crankshaft, means for adjusting the effective location of the die mounting surface of the slide with respect to the location of the lower end of the connecting rods, the said throws pertaining to one of said slides being angularly offset from the throws pertaining to the other whereby upon rotation of said crankshaft one of said slides will lead the other thereof in both directions of movement of the slides, said outer slide has parallel front and back portions and parallel side portions perpendicular to said front and back portions, said portions defining a rectangular opening extending through said outer slide to receive said inner slide, said first means comprising cooperating elements of first giv means on said uprights and on the corners of said outer slide having angularly related interengaged first guide surfaces, said second means comprising cooperating elements of second gib means in opening in said outer slide and on the corners of said inner slide having interengaged second guide surfaces parallel to said first guide surfaces, the height of said outer slide in a direction of the axis of the said opening therein being substantially greater than the height of said inner slide measured in the same direction.

Claim 8

In a mechanical press; a press frame having a crown and a bed and uprights extending between the crown and bed, an outer slide, first means guiding said outer slide on said uprights for movement toward and away from the bed, an inner slide, second means guiding said inner slide in said outer slide for movement parallel to the movement of the outer slide, a crankshaft rotatable in the crown, a respective pair of throws on the crankshaft for each slide, and a respective pair of connecting rods for each slide, each connecting rod having one end pivotally connected to the respective slide and the other end engaging a pertaining throw of the crankshaft, means for adjusting the effective location of the die mounting surface of the slide with respect to the location of the lower end of the connecting rods, the said throws pertaining to one of said slides being angularly offset from the throws pertaining to the other whereby upon rotation of said crankshaft one of said slides will lead the other thereof in both directions of movement of the slides, said outer slide has parallel front and back portions and parallel side portions perpendicular to said front and back portions, said portions defining a rectangular opening extending through said outer slide to receive said inner slide, said first means comprising cooperating elements of first giv means on said uprights and on the corners of said outer slide having angularly related interengaged first guide surfaces, said second means comprising cooperating elements of second gib means in opening in said outer slide and on the corners of said inner slide having interengaged second guide surfaces parallel to said first guide surfaces, the height of said outer slide in a direction of the axis of the said opening therein being substantially greater than the height of said inner slide measured in the same direction.

Claim 9

A mechanical press according to claim 6 in which said first guide surfaces comprise a pair of angularly related surfaces at each corner of the outer slide and said first gib means being adjustable for selectively adjusting said angularly related surfaces relatively.

Claim 10

A mechanical press according to claim 6 which includes means for supplying fluid under pressure to the said interengaged guide surfaces, and catch trough means beneath said gib means for receiving fluid which drains from said guide surfaces.

Claim 11

A mechanical press according to claim 8 in which said guide surfaces are vertical and said catch trough means includes a trough in said outer slide under each second gib means and a trough in said frame under each first gib means, said troughs adapted to drain to a collection regIon from which the fluid can be returned to said guide surfaces.
