    Abstract: A workpiece is held between a movable clamping element (56) and a stationary clamping element (52). During setup, a hex drive (58) is rotated to move a traveler (100) which is connected to the movable clamping element along a threaded shaft (80). The threaded shaft is supported at one end through a spring retainer nut (88), a spring (86), and a bearing (82). After the movable clamping element engages the workpiece, the spring is compressed, limiting the amount of clamping force applied to the workpiece. The retainer nut (88) is selectively moved through the use of the tool to a selectable position along the threaded shaft (80) to adjust the spring compression, hence the clamping force. After initial setup, an electrochemical actuator (110) is actuated to melt a polymer, forcing a piston assembly (118, 120) and a bearing (84) to shift the threaded shaft (80) longitudinally against the spring, moving the clamping elements apart a short distance to release or receive a workpiece.

  • Patent number: 4961702
    Abstract: A retainer for use in connection with injection molding that is used to retain a slide in its open position when the mold is opening. The retainer has two pivotally connected jaw members and a coiled compression spring that applies spring pressure to the jaw members as these members engage a pin that is connected to a slide when the mold is opening. The construction of the jaw members avoids undesired spreading when the pin engages the jaw members and the jaw members are constructed in a manner that enables the retainer to be easily assembled. The retainer jaw members completely surround the coil spring and protect it from dirt and only a portion of the ends of the coil spring exert a force upon the jaw members when the retainer is in use.

  • Patent number: 4848723
    Abstract: An overload protection device for the clamping portion of a tube cutoff die set. The overload protection device is used to prevent destructive overload forces in the event a mechanical obstruction prevents the tube clamping die jaws from fully closing in response to the forces applied by a control cam. The overload protector comprises a wedge mounted between rollers. If overload occurs the wedge is squeezed out of position against the operation of a compression spring. After the overload condition is eliminated the wedge is returned to position by the compression spring.

  • Patent number: 4815648
    Abstract: A hand-held welding device utilizes a multiple upset cold pressure welding technique to join abutting end surfaces of a pair of wire members. The welding device includes a pair of spaced-apart, parallel tie rods for supporting a stationary V-block in spaced apart relationship with a moveable V-block. A welding die assembly is positioned between and is actuated by the two V-blocks. An end plate is secured to one end of the tie rods adjacent the stationary V-block, while a fixed handle is adjustably secured to the opposite end. A moveable handle is pivotally mounted relative to the fixed handle and includes a working roller which engages the moveable V-block to force the V-blocks against the die assembly. As the V-blocks are forced against the die assembly, the die assembly is operated to force the ends of the wire members against one another to form a cold pressure weld.

  • Patent number: 4756518
    Abstract: In a fiber-gripping device has a gripper head provided with a V-groove for housing an optical fiber and an elastically deformable holding member which is brought to bear on the optical fiber. The gripper head and holding member are provided with V-section channels located respectively in oppositely-facing relation. A cylindrical rod forming a pivot-pin is placed between said oppositely-facing channels. The device is caused to open by a spring which tends to produce a movement of pivotal displacement of the holding member away from the gripper head. A locking lever is adapted to move into a first position in which the holding member is located at a sufficient distance from the gripper head to permit free passage of the optical fiber and a second position in which the holding member fixes the optical fiber within its V-groove and exerts a force which is controlled by its own elastic deformation.
