Filed: 1990-06-25
Abstract: PURPOSE:To provide an electromagnetic relay able to set the contact pressure at least a prescribed level and having resistance to contact fusion and deposition by driving a movable contact piece forcedly by rotation of an armature. CONSTITUTION:A movable block 3 installed in a card 30 together with an electromagnetic block 2 is put in a base 1 and rotated by magnetization and demagnetization of the electromagnetic block. For example, when an armature 20 rotates contraclockwise, a movable contact point 24a comes in contact with a fixed contact point 10a. Then, a pushing part 32a in the upper part of a card 30 fixed in the armature 20 presses the upper plane of a movable contact piece 21 forcedly. Consequently, contact pressure becomes high as compared with that in the case that the movable contact piece 21 moves only spring force. Meanwhile, when the armature 20 rotates clockwise from the previous state, the pushing part 32b in the lower part of the card 30 comes in contact with the lower plane of the movable contact piece 21 and the movable contact piece 21 is forcedly driven to part the contact points even if the movable contact point 24a and the fixed contact point 10a are fused and deposited.

IPC: B21D43/05
Filed: 1993-06-11
Abstract: PURPOSE:To add a convenient work reversing function to the transfer device of a forging press. CONSTITUTION:An actuator 2 is attached to the rear face 11 of a beam 1 for a freely intermittent operation. A spline boss 31 is fixed on the rear end of a finger rest 3 in the beam and engaged freely slidably in the horizontal direction with a spline shaft 21 which is rotated by receiving the activation of the actuator. Consequently, switching is performed with one operation in accordance with the need for reversal/nonreversal. The device is simply structured and hard to fail. Since the reversing time is freely set, interference between a work and a die is avoided. The actuating part may be hermetically sealed so as to be protected from an adverse effect such as heat and scale.
