摘要:
A coolant feeder in a tool holder assembly which comprises a rotary shaft (10) mounted to the spindle of a machine tool and a stationary support member (11) rotatably supporting the said rotary shaft (10) in which the stationary coolant feeding ring (13) in communication with the radial passage for the tool (12) provided on the rotary shaft (10) axially is fitted over the rotary shaft (10) adjacent to the said stationary support member (11) and the stationary coolant feeding ring (13) and the coolant coupling device (14) on the machine tool side are connected with the coolant pipe (15) and the hollow (16) of the said coolant coupling device (14) is allowed to be in communication with the annular groove (17) of the stationary coolant feeding ring (13) via the radial passage (18) of the said coolant pipe (15) and only removing the stationary coolant feeding ring (13) from the rotary shaft (10) enables repairing of a series of coolant passages to the tool to be installed to the rotary shaft without removing the stationary support member (11) from the rotary shaft.

The machine for creasing and cutting an endless web of cardboard or the like comprises at least two pairs of creasing rollers (21, 22, 24, 25) and at least two pairs of cutting rollers (32, 33, 34, 35); the web of cardboard being processed passes between the rollers (21, 22) of a first pair of creasing rollers and the rollers (32, 33) of a first pair of cutting rollers, while the other pair of creasing rollers (24, 25) and the other pair of cutting rollers (34, 35) are situated in inactive positions in which there operate means (184, 184 min ) for the positioning of the respective tools; the two pairs of creasing rollers (21, 22, 24, 25) and the two pairs of cutting rollers (32, 33, 34, 35) are carried by an angularly mobile assembly (17, 17) which alternately assumes one or other of two angular positions in order to arrange one or other of said two pairs of creasing rollers and one or other of said two pairs of cutting rollers in the working position. (Fig. 5).
摘要:
Bei Nibbelmaschinen ist die Matrize 4 mit dem Antriebskopf 1 über ein Tragglied 5 verbunden. Um die beim Nibbeln auftretenden sehr hohen Kräfte an der Verbindungsstelle auffangen zu können, weisen der in der Aufnahmeöffnung 9 am Antriebskopf 1 drehbare Zapfen 8 quer zu seiner Längsachse ein oder mehrere Vorsprünge und die Aufnahmeöffnung 9 der Anzahl der Vorsprünge entsprechende Querausnehmungen auf. Außerdem ist eine Verdrehsicherung 18 für den Zapfen 8 vorgesehen, wobei dieser mit seinem Umfang in mindestens einer Drehstellung gegenüber der Aufnahmeöffnung 9 über die Länge derselben hinweg innerhalb des Aufnahmeöffnungsquerschnittes liegt und in wenigstens einer anderen Drehstellung diesen Querschnitt mit seinen Vorsprüngen überragt.
摘要:
The vertically reciprocal upper blade assembly of a sheet metal squaring shear is activated in a substantially vertical path past a fixed lower blade (16) by means of one or more reciprocal rotary hydraulic actuators (19). The output drive shaft (18) of the hydraulic actuator(s) (19) is connected to one or more drive straps (26) by an eccentric cam (30) which is keyed to the drive shaft (18) and rotatably received within the straps (26). The horizontal gap between the upper blade (25) and the lower blade (16) is precisely controlled by suspending the blade supporting gib bracket (20) from pins (50-52) on the side walls (10-12) of the apparatus housing and adjustably connecting the gib plate to the pins by eccentric cams (58). The gib mounting system also provides for adjusting the angle of the upper blade (25) with respect to the lower blade (16). An improved hold down assembly limits the stroke of the hold down pins (116) to maintain a slight clearance (z) between the hold down pins (116) and the bed surface (14) at all times. A unique hydraulic actuator mounting bracket (150) facilitates alignment of the actuator (19) with the drive shaft (18) by permitting adjustment of the actuator (19) relative to the shaft (18) after the shaft (18) is properly mounted and aligned in the machine frame (10).
摘要:
A slitter scorer wherein a pair of rotating drive shafts (SA, SB) and roll heads (HA, HB) each secured onto respective said rotating drive shafts in an opposing position are provided and sheets fed between said roll heads are processed, a head replacing device is provided, wherein a plurality of pairs of shafts for holding heads (1a, 1b, 2a, 2b), having diameters equal to those of said pair of rotating drive shafts (SA, SB) and capable of being disposed concentrically on the extensions thereof, head replacing means (8, 9, 10) to replace said plurality of pairs of shafts for holding heads, roll heads (Ha, Hb) held on said shafts for holding heads, and transfer means (4, 11 to 15) to transfer roll heads in the axial direction are provided and roll heads (HA, HB) on said rotating drive shafts are replaced with roll heads (Ha, Hb) on said shafts for holding heads by sliding them on said rotating drive shafts (SA, SB) and said shafts for holding heads (1a, 1b, 2a, 2b) respectively.
摘要:
An improved billet shear for use in a horizontal continuous casting system comprises a pair of oppositely positioned hydraulic cylinders (24, 25) and a pair of inwardly facing shearing blades (11, 12). The shearing blades (11, 12) are multi-faceted to produce simultaneous shearing of the casting and camming of the casting separations during the shearing process.
