摘要： The present invention provides a metal forming system, comprising a platform and a gantry means, in which the platform is provided with a plurality of lower mold bases bearing sheet metals, while the gantry means is provided with at least one upper mold base and a toggle unit. The gantry means is performing lateral displacement on the platform, so as to be displaced to a location above the lower mold base which is predetermined to operate. The toggle unit is for adjusting the longitudinal position of the upper mold base so as to change the distance between the upper mold base and the lower mold base, resulting in determining whether a mold-closing state or a mold-opening state. A metal forming operation is performed on the sheet metal between the upper mold base and the lower mold base so as to manufacture a metal formed part when the mold-closing state.

摘要： The invention relates to a device for punching, stamping and/or shaping flat elements (29), comprising a base body (1) with a table (18) and support (26) for the flat element (29), and comprising a base plate (17), which supports a punch (24) and which, in order to carry out the working process, can be advanced with the aid of a drive (4,5) toward the support (26) and into a working station (II) whereby bringing the punch (24) into contact with the support (26) and can be moved away therefrom. The aim of the invention is to create a device of the aforementioned type with which a large number of very short and highly precise punching strokes can be executed in succession in order to make punched holes or stampings and, in particular, short stop periods and thus short clock times, in fact, the shortest possible working strokes, can be achieved in the event of fast moving flat elements. To this end, the invention provides that transfer means (9, 7; 35; 43; 46) are coupled between the drive (4,5) and the base plate (17). These transfer means move the base plate (17) essentially without building up any pressure from a position of rest (I), in which the punch (24) is not in contact with the support (26), up to immediately in front of working position (II), then they move the base plate into working position (II) along a short distance while producing a high pressure between the base plate (17) and the flat element (29). During further operation of the drive (4,5) over areas, the base plate (17) is returned to the position of rest (I,II) in the opposite direction of movement essentially without building up any pressure.

摘要： The invention proposes a novel drive with electrical power control for machines which have to execute cyclic movements with high accelerations. An electric motor drives a pump which, in turn, is connected directly to a cylinder. This arrangement has added to it a system of pressure accumulators and valves which give the system the property of an oscillator. The acceleration forces in the event of a cyclic movement near to resonance are then exerted largely by the pressure accumulators and the cylinders connected to these. This leads to a relieving of the electric motor and makes it possible to install lower powers on the machine or else, for the same power, achieve shorter cycle times of the machine.

摘要： The invention relates to a hydromechanical drive system for at least one press ram of a cutting and/or forming press, at least one drive cylinder being connected to a following kinematic chain. This kinematic chain is designed in such a way that a complete ram stroke, i.e. a downward motion and an upward motion, is effected during a single piston stroke in only one direction. In addition, the proposed drive system has mechanical controlled synchronization.

摘要： In a two cycle air cut-off press having a bed plate, guide posts, a top plate upon the posts and a ram plate guidably mounted upon the post defining with the bed plate a die set area an improved power mechanism for the ram plate including first and second cylinder assemblies mounted upon the top plate including piston rods. A bell-crank is pivotally mounted upon the top plate and pivotally connected to the piston rods. A toggle linkage including a plurality of pairs of pivotally interconnected upper and lower links at their outer ends are connected respectively to the top plate and to the ram plate. A horizontally reciprocal control arm is connected to the toggle linkage and to the bell-crank whereby on alternate reciprocal movements of the piston rods and reciprocal pivotal movements of the bell-crank, the control arm is reciprocated and through the linkage effects reciprocal vertical movements of the ram plate. In the modified cut-off press the bell-crank is omitted and the cylinder assemblies and piston rods are mounted upon side plates, with the piston rods connected to opposite ends of the control arm, for reciprocating the control arm and the toggle linkage vertically reciprocating draw rods connected to the arm plate.

摘要： A closing and locking device for a press comprising a stationary plate, a stationary head spaced from the stationary plate, and a mobile plate movable toward and away from the stationary plate. Movement of the mobile plate is controlled by a double acting piston-cylinder mechanism. A toggle arrangement is pivotally connected between the mobile plate and the stationary head. A second double acting piston-cylinder mechanism operates, after the first piston-cylinder mechanism moves the mobile plate toward the stationary plate, to position the toggle arrangement for locking the mobile plate in place. The entire closing and locking device is arranged within the external contour of the press. The toggle arrangement plays no part in the major portion of the movement of the mobile plate with respect to the stationary plate, but is activated only to lock and unlock the mobile plate. Provision is made for slowing the flow of fluid to the first piston-cylinder device to permit degassing during compression molding of resins containing expanding agents.

摘要： An apparatus for cutting sheet materials comprises a support frame for supporting the material to be worked and a cutting tool operatively movably connected to the support frame and effective to move from a retracted position to a cutting position. Means are provided to drive the cutting tool without interruption in one continuous cutting cycle from a fully retracted position to a cutting position, then to an intermediate position between the cutting and retracted positions, then back to a cutting position substantially immediately, and thereafter to the fully retracted position. This is accomplished by a driving mechanism comprising conventional toggle arms driven by a piston which moves from a withdrawn position to a fully extended position and back to the withdrawn position during the cutting cycle. The toggle arms are driven past their position of alignment twice during the movement of the piston and this is effective to reciprocally drive the cutting tool twice into cutting position during a single cycle. As a result, the material is quickly cut at the same location twice in succession, thereby ensuring a complete and accurate severing action.
