Abstract:
An improved apparatus for trimming an irregular open end of a container body is disclosed. The improved trimmer cartridge includes a sealed gear housing, for retention of interior lubricant and to reduce contamination. An adjustment mechanism, accessible from the exterior of the housing, is provided to adjust a gap between two blades of the trimmer cartridge. The adjustment mechanism provides improved control over the gap width, which is between 8-25% of the can metal thickness. Additionally, a tang that is removably connected to a shaft for a first blade provides rotational power for the trimmer. The tang is replaceable without requiring the housing to be opened or requiring replacement of the blade shaft. Another blade shaft is provided for a second blade, with the two blade shafts having substantially equal mass. The trimmer also includes spur gears, which do not have the thrust load associated with prior art helical gears.
Abstract:
A fluid form that is used to produce deep-drawn articles (cf. 10) on any presses, and includes a ram (2), a hold-down plate (3) and a die (4), which can be filled, preferably, with water, wherein the sheet metal (10) to be deep-drawn is guided transversely between die and hold-down plate, should be improved in such a manner that no additional tools are required to trim the deep-drawn articles (cf. 10) and, optionally, for other operations. Hereby, the configuration of the respective fluid form as combination tool (1) is provided for the deep drawing operation and for further operations, such as trimming, wall profiling, notching, perforating or the like.
Abstract:
Apparatus for trimming cylindrical cans wherein each can is orbited about a central turret axis while being rotated about its longitudinal can axis is disclosed. The cans are successively mounted with vacuum onto a support mandrel located on a support shaft within each of plural cartridge assemblies mounted at circumferentially spaced intervals on a turret disk. The can is firmly secured to the mandrel by vacuum so that the open end portion of the can body projects between an outside circular cutting knife and an inside trimming edge disposed within the open end. As the cartridge orbits about the turret axis on the shaft axis, the inside trimming edge is radially displaced by camming action into contact with the open end portion of the can body and the outside cutting edge to generate cutting forces for trimming the portion. This trimming occurs as the inside trimming edge is maintained radially closer to the turret axis than the can body and the outside cutting edge which remain centered on the cartridge axis. In the preferred embodiment, however, this trimming can occur by gradually camming the entire circumference extent of the inside trimming edge into contact with the can body without rotating either the trimming edge, outside cutting edge, or can body in relation to the cartridge axis. By locating the can supporting mandrel on the cartridge shaft, set-up of trim height and trim quality is self-contained within the cartridge which allows for set-up and quality verification in the tool room before the cartridge is placed in a production machine.
Abstract:
A cutting apparatus includes a mandrel insertable in a food product container. The mandrel supports the container in a fixed position by contacting an inner surface of the container. The mandrel is locatable on a support apparatus so that as the mandrel and container are rotated on the support apparatus, the container remains in a fixed axial position. Spaced-apart cutting knives contact an outer surface of the container to cut the sample therefrom while the mandrel and container are rotated.
Abstract:
The can trimmer includes first and second supports adjustably mounted on bars for adjustably spacing the supports from one another dependent upon the height of the cans to be trimmed. The supports mount a motor-driven splined shaft for rotating first and second carrier wheels and star wheels between the carrier wheels. Cam-actuated pushers are mounted on the pusher carrier wheel and mandrels are carried on the other carrier wheel in axial opposition to the pushers. Cam-actuated trim heads are pivotally carried by the second carrier wheel for movement toward and away from the mandrels, respectively. Upon disposition of cans on the star wheels between the pushers and mandrels, the pushers carry the cans onto the mandrels for cutting by the trim heads. Air pressure pushes the cans off the mandrels in following engagement with the pushers for discharge.
Abstract:
Apparatus for trimming away the open end of an untrimmed can body using a plurality of can trimming apparatuses mounted on a rotating turret wherein each can trimming apparatus has a rotatable first shaft having a radially outer or inner knife and a knurling roller mounted thereon for rotation therewith and a second rotatable shaft having a radially inner or outer knife and a knurling segment mounted thereon for rotation therewith and wherein, for each complete revolution of the turret, the first shaft makes three complete revolutions and the second shaft makes one complete revolution. Also, an arrangement of gears is provided for rotating the firs and second shafts.
Abstract:
A trimming tool for trimming drawn parts over their complete periphery and for the simultaneous transverse cutting of the waste strip which has been cut off achieves complete and fragment-free transverse cutting of the waste strip by way of a low-maintenance, reliable tool which does not limit the space for introducing and removing the workpiece. The transverse cutting takes place by rectilinear further motion of a transverse cutter integrated in a fixed location in the upper tool. Its shear edge is freed in ample time by a controlled escape motion of a make-up cutter. The make-up cutter permits a complete and clean trim cut to be carried out on the workpiece and also permits the shear edge of the transverse cutter to extend right up to the trim shear edge. Because of the rectilinear downward motion of the transverse cutter, the waste strip is also sheared off cleanly and without cracks as far as the innermost trim cut edge.
Abstract:
The excess covering material is trimmed from a workpiece using a blade assembly having side by side blade segments with cutting edges aligned with the contour to be cut. A rubber roller applies a longitudinal cutting force to the blade segments in sequential fashion by rolling across the blade segments ends opposite the cutting ends. The blade segments are returned to the noncutting position by a tension wire threaded through a notch in the shaft of each of the blade segments. Cutting pressure is adequate to cut through at least three layers of covering material without scoring the substrate. The rubber roller provides certain resiliency which helps control the cutting pressure.
Abstract:
An apparatus for cutting through transversely or trimming pipes, pieces of tubing or cans by means of two cooperating shearing members having each a cutting edge which extends in a circular or otherwise closed line. These shearing members are mounted for relative radial wobbling shearing movement. There are provided in the apparatus also means for keeping the cooperating cutting edges at a safe axial distance from one another to avoid, during operation, damage to them, said means at the same time allowing the shearing members to relatively move in all radial directions to achieve the wobbling shearing operation.
