摘要： A device for integrally joining a metal block (11′) that can consist of a number of plates, by hard-soldering or brazing. The hard-solder provides a connection covering a large surface and with a minimal thickness in solder gaps (17j; j=1, 2, . . . , n−1) located between adjacent segment plates (12i; i=1, 2, . . . , n). At least one capillary solder inflow path (14) is provided. Said solder inflow path starts at a solder depot containing a supply of hard solder or braze material (42), which melts as the stack (11) of plates is heated. The melted solder material flows directly to the individual, also capillary solder gaps (17j; j=1, 2, . . . , n−1) via said solder inflow path, the solder gaps being provided between surfaces of the segment plates (12i) that face towards each other.

摘要： A hydrostatic axial piston machine employs a swash plate construction in which the diagonal position of the swash plate can be controlled by at least one positioning piston pressurized with a control pressure. A control valve is in a line which leads to at least one positioning piston. A simple electrical-hydraulic control of the swash plate can be accomplished by the electrical actuation of the control valve. The control valve may be in the form of a rotary disk valve which can be actuated by a stepper motor.

摘要： A hydraulic idling-regulating valve comprising at least two mechanically operated through-flow valves which can be controlled to move alternatively into a flow position and a closure position and which are both closed in a neutral central position. An electromechanical specified-value setting system positions the piston of a hydraulic drive cylinder, which system comprises a hollow shaft that can be rotated by a number of revolutions correlated with the specified value, and an actual-value feedback system is provided which comprises a feedback spindle which is in engagement with an internal thread of the hollow shaft and which performs a number of revolutions correlated with the piston movement. The valve-actuating element is subjected to the same displacements as the specified-value setting shaft. A casing is provided with a circular cylindrical core having a first longitudinal bore for accommodating the pistons of a pair of valves for displacement between longitudinally movable stop elements, and another bore accommodating the hollow shaft in rotatable and displaceable relationship. The stop elements are axially and radially supported at the hollow shaft by pivot pads. The casing is provided with a circular cylindrical envelope. The connection spaces on the pressure-source side and on the consumer side are delimited by external grooves in the cylindrical core, inlet and outlet ducts are defined by radial bores in the core and in the envelope.

摘要： A hydraulic drive system for a machine element performing in one work cycle a sequence of motions comprising a rapid feed motion, a working stroke under load and an oppositely directed rapid-return motion. The drive element includes a hydraulic cylinder having three working surfaces A.sub.1, A.sub.2, A.sub.3. Motion control is effected by an electro-hydraulic follow-up control valve with a pre-setting device controlled by a stepping motor and a mechanical actual-value feed-back device. During rapid feed motion, the relatively small working surface A.sub.1 is subjected to the output pressure of the follow-up control valve only, while during the working stroke the pressure acts additionally on the working surface A.sub.3. The rapid-return movements of the piston of the cylinder are controlled by applying pressure to the working surface A.sub.2, or by relieving pressure from the two other working surfaces A.sub.1 and A.sub.3. A pressure-controlled reversing valve is moved by the output pressure of a pilot valve control arrangement into its operating position corresponding to the working stroke when the output pressure P.sub.A of the follow-up control valve exceeds a pre-determined threshold value P.sub.sl, and returned to its operating position corresponding to the rapid motion conditions when the output pressure P.sub.A of the follow-up control valve has dropped to a value P.sub.s2 below or at least equal to the value P.sub.s1.A.sub.1 /A.sub.L, wherein in the particular case described L.sub.L =(A.sub.1 +A.sub.3).

摘要： A workpiece being processed on a machine tool is moved by control devices to the tool head or work station of the machine mechanically or automatically. A stop defines an area around the work station from which the holding devices must be kept to prevent damage. As soon as a holding device reaches the limit of the danger zone around the tool head, it is switched into a setting releasing the workpiece and moves into a position away from the work station. The machine has a switching element connected to each holding device to be so movable, and the switching element has a switching slide which is acted on by an applied force and is supported in a first position until it abuts the stop when one slide position connects the energy source to the drive of the holding device to move it away from the stop. In another slide position, the connection to the energy source is broken and the holding device returns to the workpiece holding position.

摘要： A hydraulic drive mechanism for a punching or an embossing tool, with a double-acting drive hydrocylinder with differently large piston areas, the rapid feed operation, the working feed operation, as well as the rapid retraction operation being controllable by the joint or alternative pressurization of these piston areas. For effecting switchover, an area switching valve is provided which switches over, once the driving pressure exceeds, for example, 90% of the maximum initial pressure of the pressure supply unit, from differential operation to unilateral pressurization of the larger drive area. The area switching valve comprises a check valve acted upon, in the opening direction, by the operating pressure in the smaller driving pressure chamber. A locking spring force of the check valve is equivalent to an opening pressure of about 90% of the supply pressure. The area switching valve comprises a pressure-regulated slide valve having a valve body constructed as a stepped piston urged against the check valve body by a return spring. With the check valve being closed, the smaller drive pressure chamber is pressurized. With the check valve being opened, the smaller drive pressure chamber is pressure-relieved, and the larger piston step of the stepped piston is under the pressure ambient in the larger drive pressure chamber. The ratio of the area of the larger piston step to the cross-sectional area defined by the valve seat of the check valve is larger than the ratio of the larger piston area to the smaller piston area of the hydro-cylinder.

摘要： A hydraulic drive unit has a tracking regulator valve (19) for controlling a servo drive (18) of a main control valve (16), where the main control valve controls flow to a hydraulic motor (11). The tracking regulator valve is controlled by an actuating element (42), which is controlled by a comparison of a nominal position value, set by an electric motor (36), and an actual position valve, generated by a mechanical feedback (53) connected to the hydraulic motor. The main control valve includes a slide valve piston (87), which forms a housing for the tracking regulator valve, which has two piston slide valve elements (39, 41). The slide valve piston (87) of the main control valve (16) has an axial through-bore (122) through which passes the actuating element. The servo drive (18) is a dual-action hydraulic cylinder, which includes drive pressure chambers (33, 34) formed by axial blind bores (118, 118') in the valve piston (87) of the main control valve (16) and pistons (138, 138') accommodated in the blind bores.

摘要： A hydraulic driving arrangement for circular indexing tables for the precise positioning of workpieces, with the exact position of the workpieces being determined by an index. A hydraulic motor is provided with an electro-hydraulic follow-up governor using a stepping motor for setting the desired values and a mechanical actual value indication arrangement. A monitoring arrangement positively coupled with the circular indexing table and/or a driving gear of the hydraulic motor indicates whether or not the circular indexing table is in a position suitable for bringing the indexing gear into engagement and, if so, emits a signal triggering the indexing process or, if the circular indexing table is not in the desired position, deactivates the indexing mechanism. The monitoring arrangement comprises a cam disk coupled with the circular indexing table via a gearing so that it performs exactly one rotation by 360.degree. between two desired positions.
