摘要:
The invention related to a pyrotechnic circuit breaker (1) comprising: a body (10), a piston (40) slidably mounted in said body along a first direction (Z), said piston having a first protrusion (42) comprising a cutting edge (42a), a pyrotechnic igniter (30), and a bus bar (50). The piston is adapted to move from a raised position to a lowered position to cut the bus bar into two distinct portions (50a, 50b) upon activation of the pyrotechnic igniter (30). The piston further comprises a second protrusion (44a) extending from the lower face (43) over a greater distance (dl) than the first protrusion (d2). The bus bar (50) comprises an aperture (52a) aligned along the first direction (Z) with said second protrusion (44a), the second protrusion and the aperture being adapted to cooperate such that the second protrusion is engaged in the aperture when the piston moves from the first position to the second position.

A power tool shear accessory (100) includes an accessory housing (102), an input shaft (104), a working tool (106), and a brace (130). The input shaft (104) is driven by a power tool (10) and drives the working tool (106). The brace (130) rigidly connects the accessory housing (102) to a power tool housing (12). The brace (130) includes a collar (132) coupled to the accessory housing (102), a clamp assembly (140) that may be rigidly connected to the power tool housing (12), and an arm assembly (134) connecting the collar (132) to the clamp assembly (140). The collar (132) allows selective rotation of the accessory housing (102) relative to the collar (132) while the brace (130) rigidly couples the accessory housing (130) to the power tool housing (12). The arm assembly (134) may have a single arm. The clamp assembly (140) may be coupled to a base of a handle of the power tool (10) with arm assembly at an angle to a working axis of the power tool (10).

A hydraulic rescue tool (10) with a quick-change head (26) that incorporates a cylinder (20) having a piston rod (22) and a forward end structure (24). The forward end structure (24) has a separable head and a cylinder attaching bifurcated yoke (28). A pair of yoke quick release pins (48) jointly engage the head (26) and the bifurcated yoke (28) thus, creating an attachment therebetween. A pair of cutting blades (50) are connected to the head (26), and links (54) connect to the piston rod on a first end and to the cutting blades (50) on a second end, thereby forcing the cutting blades from an open position to a closed position by movement of the piston rod (22). A pair of link quick release pins (60) engage the links (54), creating an attachment therebetween, permitting the links to be released by manually disengaging the quick release pins, thereby allowing the head, including the cutting blades, to be rapidly removed or repaired.
摘要:
Machine tool (5) for shearing a profiled contour on the free edges of a protection metal sheet (31) to be placed vertically over the ridge of a roof made with covering metal sheets (36) of shaped cross-section. The machine (5) includes means of guide (11,22) within which means(14) holding a punch (18) are slide-driven into approach with a matrix (26) open and fixed to said means of guide (11,22). In addition to means (7) for the operation of the punch holder means (14) and to means (10) that transmit motion to the punch holder means (14) are also included means (30,34,37) which permit a shearing of ridge sheet (31) that corresponds precisely to the contour of covering sheets (36) it overlaps even when the covering sheets (36) show uneveness of installation.
摘要:
Es wird eine Blechschere mit einem Gehäuse (11) angegeben, in dem ein motorisch angetriebener Stößeltrieb aufgenommen ist, der einen Stößel translatorisch hin und herbewegt, mit einem vom Gehäuse (11) quer abstehenden Schneidtisch (16) zur Führung der Blechschere anzuschneidendem Schnittgut, und mit einem Stößelmesser (24) am unteren, dem Schneidtisch (16) zugewandten Ende des Stößels, das mit einem am Schneidtisch (16) gehaltenen Schneidtischmesser (22) zum Schneiden des Schnittguts zusammenwirkt. Am Stößel ist ein seitlich abstehender Niederhalter (34) für das Schnittgut vorgesehen, der abgetrenntes Schnittgut in Richtung auf den Schneidtisch (16) beaufschlagt. Durch den Niederhalter wird ein spiralförmiges Aufwickeln des abgetrennten Schnittgutes vermieden und erreicht, daß das Schnittgut glatt aus der Schnittfläche herausläuft.
摘要:
Machine de découpage actionnée manuellement, entraînée par une perceuse ordinaire, destinée au découpage de tôles métalliques jusqu'à une épaisseur de 5 mm environ. La machine comprend un corps (1) pourvu de roues de support (24, 25), de deux roues de découpage (5, 6) agissant de concert sur le corps (1), le matériau en feuille étant cisaillé entre leurs bords coupants (18, 19). Les roues de découpage (5, 6) sont disposées obliquement en formant un angle alpha par rapport au plan normal du matériau en feuille à découper. Les faces des côtés libres (12, 13) des roues de découpage (5, 6) sont en outre biseautées à proximité des bords tranchants (18, 19) avec le même angle alpha, formant des surfaces périphériques (16, 17). Les roues de découpage (5, 6) sont également disposées l'une par rapport à l'autre de sorte que les surfaces périphériques (16, 17) sont situées dans le même plan et forment un point de pincement (20). Il est ainsi possible, après l'affûtage des bords tranchants (18, 19), d'ajuster aisément par exemple la position relative des roues de découpage (5, 6) grâce au déplacement vertical de l'une des roues de découpage.
摘要:
A device for cutting sheet material, especially sheet metal having a contoured structure such as ridges or corrugations, the device including (a) a support (21) adapted to attach the device to a power source (11) (manual, electric or hydraulic); (b) a first blade portion (15) with a first blade (19); (c) a second blade portion (16) with a second blade (20); (d) a first coupling portion (17, 13) which operatively couples the first blade portion (15) to the power source (11) and adapted to allow pivoting of the first blade portion (15) when the power source (11) is activated; and (e) a second coupling portion (18, 14) which either (i) operatively couples the second blade portion (16) to the power source (11 ) and is adapted to allow pivoting of the second blade portion (16) when the power source (11) is activated or (ii) is adapted to prevent the second blade portion (16) from pivoting when the power source (11) is activated, as required; wherein the pivoting of the first blade portion (15) and/or the second blade portion (16) provides a cutting action by the first blade (19) and the second blade (20). When only a single blade is to pivot, it is the lower blade which pivots upwards to meet the fixed second blade. The coupling portions (15, 16) can be adapted to enable a required grade of cut to be pre-determined from the cutting action of the device.
