Abstract
Abstract The travelling cutting machine for use with an extrusion press according to the present invention comprises a truck freely movable in the direction in which a continuously manufactured metal rod is carried, a cutter provided with blades for cutting the metal rod carried on the truck, a drive means for causing the truck to travel back and forth, a magnetic clutch or eddy-current coupling motor for coordinating the travelling velocity of the truck with that of the metal rod by connecting or disconnecting the truck with the drive means and a means for operating the truck and cutter by detecting the length of a metal rod continuously drawn out of a manufacturing apparatus, thereby to cut the metal rod by turns to a prescribed length at all times without causing the deformation of the rod.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
204 words
A travelling cutting machine for use with an extrusion press comprising in combination; a. a truck (13) movable in the direction in which a continuously manufactured rod (D) travels; b. a cutting machine (B) mounted on the truck (13) provided with cutter edges for cutting said rod (D), hydraulic pressure means (22) coupled to said cutter edges and switch means (49) to cut off said pressure means (22) when at least one of said cutter edges reaches a predetermined position; c. drive means including a motor (48) and clutch mean for coordinating the travelling velocity of the truck (13) with that of the travelling metal rod; d. switch means and roller means determining the length of the rod to be cut including a main switch (29) freely shifted to determine the length of the rod to be cut and resistors (R1 and R3) adjusting the torque of the clutch means; and e. shifting means including a limit switch (S4) for sensing the end of a travelling rod, an air cylinder (61) responsive to said limit switch, a push arm and slide pikE (65, 63) actuated by said air cylinder to shift the cut rod and make room for the next piece to be cut.
Claim 2
Dependent Claim
204 words
A travelling cutting machine for use with an extrusion press comprising in combination; a. a truck (13) movable in the direction in which a continuously manufactured rod (D) travels; b. a cutting machine (B) mounted on the truck (13) provided with cutter edges for cutting said rod (D), hydraulic pressure means (22) coupled to said cutter edges and switch means (49) to cut off said pressure means (22) when at least one of said cutter edges reaches a predetermined position; c. drive means including a motor (48) and clutch mean for coordinating the travelling velocity of the truck (13) with that of the travelling metal rod; d. switch means and roller means determining the length of the rod to be cut including a main switch (29) freely shifted to determine the length of the rod to be cut and resistors (R1 and R3) adjusting the torque of the clutch means; and e. shifting means including a limit switch (S4) for sensing the end of a travelling rod, an air cylinder (61) responsive to said limit switch, a push arm and slide pikE (65, 63) actuated by said air cylinder to shift the cut rod and make room for the next piece to be cut.
Claim 3
Dependent Claim
30 words
A travelling cutting machine according to claim 1 comprising a pair of wheels (102) for detecting the travelling velocity of the extruded metal rod thereby to actuate the clutch means.
Claim 4
Dependent Claim
80 words
A machine as claimed in claim 1, said drive means including a motor (48), a forward clutch (36) a reverse clutch (40) and gearing driven by said motor, the gearing being so arranged as to cause a backward run more quickly than the forward run, said motor during the forward run causing said truck to travel forward at maximum speed, said forward clutch (36) sliding if the speed of the truck (13) is faster than that of the rod (D).
