摘要： PURPOSE:To accomplish shearing of high speed material with a longer acceleration time of the edge by setting at 2 or more in integral multiplication the ratio of the rotary diameter of one edge to that of the other edge in a pair of rotary blades. CONSTITUTION:The ratio is set at 2 between the rotary diameter of the edge 3 of an upper arm 1 and that of the edge 4 of a lower arm arranged as rotary members so that the acceleration angle equivalent to about two cycles of revolution is applied for the lower arm shaft extending the acceleration time. Accordingly, the machine can accomodate the shearing of high speed material without increasing the motor capacity and the shape thereof.

摘要： PURPOSE:To eliminate relative backlash, by giving, before the start of the operation of a cutting machine, a torque in the same direction as that at the time of cutting to a main drive device and/or a speed-tuning device, and thereby making the condition of engagement of the gears of both devices the same as that at the time of cutting. CONSTITUTION:By the operation of ol-pressure cylinder 16, pinion 13 is turned and displaced in one direction via link 18 and oscillating link 19, and torque TM1 is transmitted to speed-turning device 2. In this speed-tuning device 2, torque TM1 is resolved into Tout and Tin. Tout is transmitted to epicyclic gear 11 and Tin is transmitted to differential gear 9. Each gear, 9, 11, is rotated in an arbitrary direction, and the condition of engagement of the gears of the main drive device and speed-tuning device 2 is made the same at the time of cutting by means of a torque in the same direction, and thereby relative backlash is eliminated. In this condition, epicyclic and differential main shaft gears 10, 12 of speed-tuning device 2 is rotated, via the main drive device, by a motor, and thereby, high-speed cutting is operated.

摘要： PURPOSE:To obtain reliable shearing by rotating a cutter-drum at high speed during the pause to increase its peripery speed, which is then held for rotating a frame during shearing. CONSTITUTION:During shearing process, a brake 20 is taken off so that a frame 1 can rotate with a shaft 2; the drive force given from a shaft 5 is transmitted to a bevel gear 7 through bevel gears 8, 9, 10; then the frame 1 together with the shaft 2 rotates until the axis of cutter drums 18, 19 conform to a vertical line, and the workpiece W is sheared between the two drums 18, 19. In this state, the shaft 5 does not transmit the torque to the drums 18, 19. However, during the suspension period, sufficiently large inertia of rotation or kinetic energies are imparted to these drums 18, 19, so that the drums have kinetic energy sufficiently large for the shearing of the workpiece W.

摘要： PURPOSE:To smoothly feed-reverse a material once passed through a pendulum type shearing machine for the material travelling, by providing a mechanism capable of feed-reversing the material which is once passed through the shearing machine upon abnormal operation being happened. CONSTITUTION:An upper tool rest 5 attached with an upper cutting tool 6 is provided to one of the eccentric parts of a crankshaft, slidably with respect to a frame 2. A material 17 to be sheared is cut on travelling between the upper cutting tool 6 and a lower cutting tool 7 by rotation of the crankshaft. Then, if it is necessary to feed-reverse the material 17 which has past through the shearing machine, since a trouble is happened on the next process step, a dancer roller 9 is lowered to its lower position A for absorbing the deflexion of the material which is feed-reversed. Thereby, the feed-reversing becomes possible even if the front end of the feed-reversed material is bent. Further, if the material is feed-reversed to an inlet side guide 10, the latter is tilted. Thus, the material which is once passed through the shearing machine, may be smoothly feed-reversed.
