The arcuate concave cutting edge of the blade is aligned to a pill-holding cavity in the lower jaw of the pliers such that, when the pliers are manually closed, the blade cuts an installed pill in half. The fixed crushing protrusions are mounted on a convex semi-cylindrical shell, and are aligned to pill holding cavities in a concave semi-cylindrical crushing basin in the lower jaw of the pliers such that, when the pliers are manually closed, pills in the cavities are crushed.

Abstract: A 4-way indent tool includes a indenter actuator cam arm being movable between an unactuated position and an actuated position to actuate four indenters to crimp a terminal. The 4-way indent tool includes a drive assembly movable along the drive screw between a retracted position and an advanced position. The drive assembly has a drive nut on a drive screw and a coupler operably coupled between the drive nut and the indenter actuator cam arm. The coupler moves the indenter actuator cam arm. The coupler has a spring loaded coupling between the drive nut and the indenter actuator cam arm compressed as the coupler is moved between the retracted position and the advanced position.

Abstract: A drive unit drives a slide which vertically reciprocates for pressing the workpiece. A detection unit detects positional information about the slide. A speed control unit controls the speed of the slide by the drive unit, based on motion information defining operation of the slide. A stoppage determination calculation unit sets a deceleration start point at which deceleration of the slide is to be started, based on the motion information and a set point at which the slide is to be forced to stop. A speed control unit determines whether an abnormality signal regarding transportation of the workpiece is input, when the slide reaches the deceleration start point based on the positional information about the slide detected by the detection unit. The speed control unit performs deceleration control for the slide so that the slide is stopped at the set point, when determining that the abnormality signal is input.

Abstract: A method for manufacturing a molded member includes carrying out a multi-stage drawing process and at least one finishing ironing process on a base metal sheet, the molded member including a tubular body and a flange formed at an end portion of the body. The multi-stage drawing process includes a preliminary drawing process for forming a preliminary body having a body element from the base metal sheet, and a plurality of compression drawing processes performed after the preliminary drawing process, the compression drawing processes drawing the body element while applying compressive force along a depth direction of the body element to a circumferential wall of the body element. The at least one finishing ironing process is carried out such that a mold clearance of an upper portion of the body element is narrower than a mold clearance of a lower portion of the body element.

Abstract: A metal band is first rolled in a front and then in a rear (downstream) roll stand of a multi-stand rolling train. A looper between the roll stands may detect a band tension in the metal band. The band tension is supplied to a first and a second tension controller to determine an application additional target value and a speed additional target value. The second tension controller may only determine a value less than or greater than 0, as the speed additional target value, if the band tension is above or below an upper or lower band tension limit. Otherwise, the speed additional target value may be 0. The first tension controller is also supplied with a target tension that falls between the band tension limits. The application additional target value may be used to act on the rear roll stand.
