摘要： A rotary microtome (1) for producing thin sections for histology is used for specimens (6) of different sizes. To maintain optimized cutting conditions, an adaptation to different specimen sizes is required without incurring disadvantages in terms of operation. An adjustment possibility is provided for the length of the vertical cutting movement (10). However, the moment that is generated by the vertical carriage (7) and that acts on the drive shaft (12) then changes. To maintain balanced moments of the drive movement, the counterweight has to be accordingly adapted by an adjustment weight (31). For this purpose, means are provided which, in an ergonomic and effective manner, permit the adjustment of the cutting stroke and also the necessary adaptation of the counterweights in one operation step. The rotary microtome according to the invention is suitable in particular in a histological routine in which mixed specimens are present in standard cassettes and also in macro-cassettes and in which, therefore, a rapid change of the cutting stroke length is desired along with good balance of the drive movement.

摘要： A punch canister includes a punch head with an axial shaft that has a screw thread which is adapted to be connected during use to the screw threads of a punch element that is slideably associated within a stripper bushing. A punch recess adjustment member is rotatably and slideably associated with the punch head. The adjustment member is adapted to the slideably but non-rotatably rotatably connected during operation to the punch element. A resilient retraction member, e.g., a spring, is located between the punch head and the adjustment member for biasing the adjustment member axially downward on the punch head. A manually releasable detent provided on the adjustment member is operatively associated with the punch head for retaining the adjustment member in any one of a plurality of selected circumferentially distributed angular positions on the punch head such that during operation disengagement of the detent allows the adjustment member and the punch element to be threaded axially on the punch head to control the distance that the punch element is recessed within the stripper bushing. In a preferred form, the detent is a lock that can be disengaged manually when the punch recess adjustment is to be made.

摘要： A press punching apparatus makes many holes at the same time and changes an arrangement of the holes without changing a punch block and a die block. A punching mold is provided with a plurality of punches having different lengths. A travel distance of the mold is adjusted so that a first part of the punches penetrates a work piece to be punched in a first stroke. Then, the travel distance of the mold is changed so that the work piece is punched by a second part of the punches other than the first part of the punches in a second stroke.

摘要： The three-side trimmer according to the present invention comprises an alignment station (F) for receiving booklet bundle (32) and aligning the booklets in the height direction, and a cutting station (D) for cutting the top edge, bottom edge and fore edge of the booklet bundle. The three-side trimmer further comprises a chuck mechanism (40) which holds the booklet bundle and conveys it from the alignment station to the cutting station. In the cutting station, there is provided a cutting table (23) for supporting a booklet bundle thereon, a top edge cutting knife (43), a bottom edge cutting knife (44), a fore edge cutting knife (42), and a pressing plate (48) movable between a waiting position, which is disposed over the booklet bundle, and a working position where the pressing plate presses the booklet bundle to the cutting table. An encoder reads the data about the rotational position of the servomotor (38) in the chuck mechanism while the chuck mechanism (40) holds the booklet bundle. The control portion (25) measures the height of the booklet bundle, on the basis of this data. The control portion controls a driving mechanism of the pressing plate, on the basis of this measured value. The control portion controls so that the waiting position of the pressing plate is adjusted to a height corresponding to the height of the booklet bundle, and the pressing plate moves up and down between the adjusted waiting position and the working position.

摘要： An hydraulic piston-cylinder assembly configured within a press machine enables adjustments to be made to the shutheight parameter through changes in the positioning of the bed in accordance with hydraulic pressure variations in the piston-cylinder assembly. The cylinder device, which is arranged to be reversibly movable with respect to the piston device under the influence of the pressure variations, is coupled to the bed such that movements of the cylinder device induce a corresponding displacement of the bed, thereby changing the shutheight. The piston device is characterized by a property of tensile elasticity in at least one dimension thereof substantially coincident with the shutheight dimension. Accordingly, in one operating mode, there may be effectuated a reversible displacement of the cylinder device beyond its established range-of-motion by changing the hydraulic pressurization of the piston-cylinder assembly in a manner sufficient to induce an elastic tensile effect in the piston device.

摘要： The present invention eases possible rubbing between an upper cutting edge and a work cutting surface during the elevation of the upper cutting edge to prevent the upper cutting edge from being worn in order to increase its lifetime. In a device for cutting a work by elevating and lowering a movable upper cutting edge 12 relative to a fixed lower cutting edge 13, an upper-cutting-edge tight-contact avoidance means 41 is provided for widening the clearance between the upper cutting edge 12 and a work cutting surface. The means 41 is comprised of a clearance adjustment mechanism 22 for adjusting the clearance between the upper cutting edge 12 and the lower cutting edge 13, and control means 35 for the clearance adjustment mechanism 22.

摘要： A mechanical press having a very precise shutheight control system is disclosed. The press includes a bed connected to a frame with a slide connected with the frame for reciprocating motion opposing the bed. The slide and bed together define a shutheight of the press. A drive mechanism is attached to the frame for driving the reciprocating slide, the drive mechanism includes a drive piston and a tie rod. The shutheight control system includes a chamber located between the drive piston and tie rod with a pressurizing mechanism in communication with the chamber for selectively pressurizing the chamber with a predetermined pressure. The pressurizing mechanism causes the tie rod to one of expand and contract to thereby control press shutheight.

摘要： A shutheight adjustment assembly of a mechanical press including an adjustment nut rotatably connected to an adjustment screw. Hydrostatic bearing pads are provided below the adjustment nut to reduce frictional forces associated with nut rotation and to provide a squeeze film thickness to withstand large press loadings. A hydraulic chamber supplied with pressurized fluid is positioned above the adjustment nut and produces a preload force on the hydrostatic bearing pads. Hydrostatic bearing pads are also arranged radially outward of the adjustment nut to radially center the nut during operation. A hydraulic chamber between the adjustment nut and screw may be furnished to resist bolster rebound during press operations.

摘要： To eliminate defects such as burr, rollover, sags, scar, etc. from cut-off surfaces of a workpiece in a turret punch press, for instance, a novel height-different punch formed with a lower front edge, an upper rear edge, and an intermediate edge extending between the two edges is used for the punch press. While feeding the workpiece on a horizontal plane in a predetermined direction, the punch is struck by a striker at a first stroke so that the lower front edge thereof cuts off the workpiece partially in cooperation with a die; at the succeeding strokes so that the intermediate edge thereof cuts off the workpiece mincingly and curls refuse within a recess of the die; and at the last stroke so that the upper rear edge thereof cuts curled refuse away from the workpiece to complete a multistroke punching operation.
