摘要:
A flexible pressing system for accepting and rejecting pressed part into a part may include a pressing apparatus configured to press components into a hole of a part and a controller programmed to receive press data for a press of at least one of the components, the press data including force, distance and time of the press, and determine whether the force is indicative of an inadequate press based on the force and distance at a specific time of the press.
摘要:
An arrangement and a method for the programming of presses is described. The programming is performed interactively by an input of points on a display screen, wherein the points determine the movement strategy x′ (α). For calculating the resulting plunger-time curve or plunger-guide angle-curve, preferably a Fourier analysis or, respectively Fourier transformation and back transformation of the curve determined by the input values is performed. In this way, a smooth and well executed kinematics plunger movement is obtained.

A system for monitoring and controlling operation of a machine having a detachable component for use in a manufacturing and/or machining process comprising a control unit for receiving one or more signals and/or data from an identification device identifying a component for use in a machine. The control unit is arranged to receive one or more signals and/or data associated with the component and to determine if a machine is operable on the basis of the received signals and/or data associated with the component. If the control unit determines the machine not to be operable on the basis of the received signals and/or data, the control unit is arranged to inhibit operation of the machine.

A process is disclosed for controlling the revolutions of the spinning roller (29) of a spinning lathe (10). The coordinate driving units (52,53), which are designed as valve controlled (49,51) hydrocylinders (42,47), are operated according to a playback process according to which the coordinate driving units (52,53) are operated according to a follow-up process in which position set values are electrically preregulated and mechanical real values are fed back. The slowing down path .DELTA.S (lag error) is continuously measured at least during the last revolution of the spinning roller (29), so that when a threshold value .DELTA.Smax is exceeded, the tracking speed V.sub.B is reduced and/or a transitioning to an intermediate routing curve occurs. A spinning lathe for carrying out the process is also disclosed.

There is provided a platemaking method of forming relief based on relief pattern data in a printing plate to be pressed on a printing matter, and the platemaking method includes the steps of: estimating distribution of printing pressure of the printing plate pressed on the printing matter on the basis of image data; calculating an amount of correction of engraving shape data on the basis of the distribution of printing pressure; correcting the engraving shape data on the basis of the amount of correction; and acquiring exposure amount data from the engraving shape data corrected. By exposure (engraving) processing based on the exposure amount data that can be acquired in this way, it is possible to form relief in consideration of deformation of a printing plate in accordance with the distribution of printing pressure in the printing plate to favorably print and reproduce an image on a printing medium.

A press monitoring and control system includes a press machine, a press configuration module and a press controller. The press machine has a lower die coupled to an upper die, wherein the lower die includes a top surface supporting a strip of material to be formed into a part after a stripper plate coupled to the upper die contacts the strip of material. The press configuration module includes an input module that processes a set of input data corresponding to a particular job and generates a data signal corresponding to the set of input data. The press controller is coupled to the press machine and the press configuration module. The controller processes the data signal, compares the data signal to a set of parameters corresponding to the particular job, and generates at least one servo signal to adjust at least one servo in response to the data signal.

A quick change device is adaptable for use on a reciprocating press fin machine which continuously forms a metal sheet into sinuous or corrugated configuration by using tools associated with upper and lower opposed, metal-engaging tools, each movable toward and away from the other in a vertical forming stroke, and a first one of these tools also being movable in a variable stroke transverse to its vertical forming stroke. Wedge-shaped abutment elements and associated block elements having a wedge-shaped cavity therein adapted to receive the abutment elements, establish the length of transverse motion of the first tool. A structure is used to simulate the reciprocating press fin machine. A reader assembly digitally analyzes movement of the wedge-shaped abutment elements to set the transverse stroke length, based on the simulation provided by the structure, to allow precise alignment of the tools in the reciprocating press fin machine.

A method and equipment for controlling a manufacturing process of a component of a tyre for vehicle wheels, wherein at least one continuous elongated element fed by a supplying member is placed on a forming support by means of at least one pressing member active on the at least continuous elongated element along an application direction. During the manufacturing of the component of the tyre, at successive sampling times Ti, the value Pi of a quantity indicative of the position of the pressing member is acquired along the application direction, where i is an integer greater than or equal to 1, Ti=i*1/f, and f is the sampling frequency.

A forming machine comprises a rotatingly drivable gripping device (1) for gripping a forming tool (2) and a material plate (3) to be formed, a movable lower slide (6), a first drive (8) for moving the lower slide, a movable upper slide (10, 35) mounted on the lower slide, a second drive (11, 34) for moving the upper slide and a holder (5) for a forming roller (4) supported on the upper slide (10, 35). A control unit (16) is provided for controlling the movement of the forming roller (4) by actuating both drives (8; 11, 34), the control unit being connected to a detector (18, 21) for determining the force exerted on the forming roller (4) and to a detector (17) for determining the position of the lower slide (6). A memory (25) is connected to the control unit for storing corresponding force/position values. The control unit (16) is adapted to control the movement of the forming roller (4 ) in dependence on the force/position values stored in the memory (25). The forming roller (4) is coupled to the second drive (11, 34) through a spring (13, 38) with a given spring characteristic. The detector (18, 21) for determining the force exerted on the forming roller consists of a position detector (18, 21) for determining the compression of the spring (13, 38).
