    摘要： The shear (11) for shearing laminar elements (35) or the like comprises a pair of blade-holders (31, 32), which, during the shearing operation, are stressed by two forces (F x and F y ) perpendicular to each other and having as their resultant, the force F R . At the shearing time, both of said blade-holders (31, 32) are supported in an inclined position, so that their main axes (20, 21) come to coincide with the direction of said resultant force (F R ). From the above, the possibility results that the mass of the inclined blade-holder can be reduced even by 50% relatively to the mass of a traditional blade-holder which is not inclined, without the stiffness of said blade-holder, relatively to the shearing forces, being endangered.
    The invention can be applied as well to guillotine shears and to rotary shears (45) equipped with roll blade-holders.

    摘要： A scrap cutter 50 is provided in a subsequent stage of the press machine 40 and cuts the scrap material fed from the press machine. The scrap cutter 50 includes: a slide 54 configured to be driven to reciprocate in the vertical direction by a Scotch yoke mechanism 57; an upper blade 55 attached to the slide 54; and a lower blade 56 attached to a frame 52 and configured to cut the scrap material in cooperation with the upper blade 55. A shear angle formed by the upper blade 55 and the lower blade 56 has an angle that gradually decreases from a start of cutting of the scrap material toward an end of cutting to allow the driving torque of the crankshaft 59 of the Scotch yoke mechanism 57 to be constant from the start of cutting to the end of cutting in cutting a scrap material of a cutting capacity limit.

    摘要： The invention relates to a shearing machine for transversally dividing especially a heavy steel plate, said shearing machine comprising an upper blade (3) which carries out a rolling cutting movement by means of an eccentric drive (8) and is held in a blade carrier (1), and a lower blade (4) which is arranged in the frame of the shearing machine (2) in a fixed manner, the upper blade carrier (1) being displaceably connected to a stand (6) of the shearing machine frame (2) by means of an articulated guiding element (5). A device for the clocked advance of a pre-determinable length of the steel plate is associated with the shearing machine, especially in the form of at least one driving element. The aim of the invention is to improve the stability of the shearing machine and thus the quality of the cut. To this end, the shearing machine is arranged between lateral stands (6, 6') of the shearing machine frame (2) which is closed by an upper traverse (7) and a lower traverse (7'). The eccentric drive (8, 8') of the upper blade (3) is arranged in the upper region of said frame, and bearings (10, 10') and driving bodies (11) of lower driving rolls (12, 12') are arranged in the lower region of said frame, in addition to a lower blade table (9) which is anchored between the stands (6, 6').

    摘要： A hoop material cutter with a movably rocking blade (3) guided by pins (12a,12b) having chamfered edges (14a,14b); part of the pins (12a,12b) protrudes sideways of associated blocks (13a,13b) which are detachable in a horizontal direction. A hopper including a lower guide (45) and a stock guide (44); the lower guide (45) abuts on the upper surface of the movable blade (3) and the stock guide (44) is set not to protrude over the position of the fixed blade (2). The width of an opening defined by the lower guide (45) and the fixed blade (2) is aproximately twice the thickness of the hoop material, and a side guide (37), whose length along the opening is set within the length of the moving blade (3), is further provided.

    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).
