摘要： PURPOSE:To improve machining efficiency for a long member by holding the long member at a fixed position, intermittently approaching and separating plural processing dies in order from one direction and next executing the machining to the end part of the long member at the prescribed position. CONSTITUTION:The long member W having modified cross sectional shape is held with a hand part 21 of a robot 2. Then, each machining die 1a, 1b,...1f is arranged in the prescribed order on a rotary table 3 equipped as intermittently turnably on a base frame 4. The robot 2 and a press machine 5 are connected as linkingly and while intermittently rotating the table 3, the machining by the machining dies 1a-1f is executed in order to the end part of the long member W. By this method, the machining for the end part of the long member W is automated and burden of worker is reduced. Therefore, processing efficiency for the long member W is improved.

摘要： PURPOSE:To improve processing efficiency for end part of a long member by arranging a rotary table having plural processing dies and press machine operating the machining die and linkingly driving the press and the table. CONSTITUTION:The plural machining dies 1a-1f are arranged on the doughnut- type rotary table 3 and the press machine 5 as vertically movable is arranged at upper part of the table 3. Non-machining side of the long member W is held to a hand part 21 of a robot 2 so as to be able to insert and rotate the work W to each working die 1a-1f. The work W is inserted in order to each machining die arranged in the machining order by intermittent turning of the table 3 and the robot 2 to execute the end part working to the work W by the press machine 5. By this method, the machining for the work W is automated and the burden of worker is reduced. Therefore, the machining efficiency for the end part of the long member W is improved.

摘要： PURPOSE:To reduce a starting torque and the inertia at a stop time by converting rotational movement of a drive motor to the linear movement of an operating plate and transmitting the linear movement to a turning gear engaging with an annular gear of a rotary table. CONSTITUTION:When an electric current is supplied to an electromagnetic valve of an air friction clutch 6, a rotary plate 8 makes one rotation but in the meantime a cam follower 9 makes a half rotation along the cam groove 11 of the operating plate 10 on the upper side from a 0 deg. position through a 90 deg. position to a 180 deg. position on the left intermediate side and advances the operating plate 10 to the left direction. A rack bar 16, too, is moved by this motion in the left direction and the friction clutch 19, too, rotates clockwise. The electromagnetic valve opens and the clutch 19 engages with the bearing side of a pinion 17 and the mounting side of a turning gear 3 to rotate a rotary table 1 at a fixed angle. A time limit switch detects this time to stop the supply of the air and the clutch 19 removes the engagement with the bearing side of the pinion 17 and the mounting side of the turning gear 3 to stop the rotation the table 1.

摘要： PROBLEM TO BE SOLVED: To provide a high speed punch press which can cut high accurate punching holes without cracks and also enables actual usage of a punch while minimizing the punch insertion volume at the time of punch processing by performing punch processing at high speed when punch processing is performed using a crank type pressing machine. SOLUTION: In this punch press using a crank type pressing machine, a fixed side link 2 rotatably connected to a fixed part 1 and a slider side link 4 rotatably connected to a slider 3 guided upwards/downwards are rotatably connected with a connection axis 5. Then, a crank shaft 12 rotating around a crank pin 11 installed in approximately horizontal to the connection axis 5, and the connection axis 5 are rotatably coupled with a reciprocating link 13. At the point before a crank angle accompanied with rotation of the crank shaft 12 reaches 90 deg., punch processing is performed by the punch installed below the slider 3 when the fixed side link 2 and the slider side link 4 extend on an approximately same line.

摘要： PURPOSE:To cope with automation and to reduce the burden of a worker by intermittently moving a rotary press side to the holding position of a long-sized member by installing at a fixed position the articulated robot side holding the long-sized member. CONSTITUTION:A long-sized member W is inserted in or pulled out of each work die 1a, 1b...1f by the hand 21 of an articulated robot 2 and held rotatably centering around the axial line of the long-sized member W. The articulated robot is arranged by being fixed with a base plate 22 to the fixed position so as to pull out, insert and rotate the long-sized member W to each work die 1a, 1b...1f by bending the joint in response to a play back or by the specified numerical control. The rotary press 1 intermittently moving to the fixed position of the articulated robot 2 is made to intermittently move the respective from one direction by a rotary table 3. Consequently it can cope with the automation and the burden of a worker can be reduced.
