Inventors: LN Bramley, WN Jenkins, LJ Chant and F Seredynski The present invention relates to forging, in particular to steel forging, more particularly to an electric control device for control or water apparatus used for transporting cast iron or blanks between successive forging operations. . The device according to the invention comprises a first, by means of the water apparatus depending on its low adjustable means, a second, adjustable means corresponding to the desired low adjustable means of the water apparatus and a control coupling actuatable by the first and second means to move the water apparatus to a lodge corresponding to the requested , in the other body installed team.

An exemplary embodiment of the invention will be described in the following in connection with the accompanying drawings, which illustrate an electric control device for a control device of edge design. The invention can be characterized in that part of the second member is electrically controllable by a rotary selector which can be moved in only one direction, the contact arms of which can be operated by circuits with contacts in selectively actuable manual switches, each corresponding to a predetermined range of motion of the control device. By thus installing the second member, which corresponds to a tin layer for the control device, is electrically operated by a rotary selector, the contacts of which contact arms are in turn controlled by stroin circuits with contacts in selectively manoeuvrable manual switches, each corresponding to a predetermined movement of the water device. operating matters and simple maneuvering. Figs. 1 and 2 show the water or control device (referred to as control device) in side view resp. plan view, Figs. 3A, 3B and 3C together form a wiring diagram for a faulty detection device for the longitudinal layer of the control device, Fig. 4 Or a wiring diagram for an electrical device for installation of the longitudinal layer of the control device, Fig. 5 Or a wiring diagram for an electrical device for installation, of the angular layer of the gripping shaft of the control device, and Fig. 6 shows a circuit diagram for a synchronous machine system, which is used for installation of the gripping shaft.

The control apparatus shown in Figs. 1 and 2 comprises a chassis or a carriage 12, which Or Abar pa. bar wheel 13 and driven by a stationary motor 14. The motor 14 drives the carriage during the transmission of a gearbox 14a, which has on its output shaft a gear 15, cooperating with a rack 16 fixed to the carriage 12. The steering apparatus Or is provided with a gripper shaft 17, which at his one spirit Or provided with a pair of gripper shafts 18 fen. to hold a got or amne, to be forged.

In addition to the gripper shaft 17 being movable longitudinally by the movement of the carriage on the wheels 13, it is also movable vertically in relation to the carriage 12 and rotatable about its own one-drum line. The rotational movement takes place with the aid of bearings 20, in which the gripper shaft Or rotationally mounted. The vertical movement takes place with the aid of a pair of links 21, which Oro articulated with the bearings 20 and with p0. chassis 12 mounted supports 21a.

The electrical device for maneuvering the control device in longitudinal direction is shown in Figs. 3 and 4. As indicated in Fig. 4, a voltage corresponding to the position of the control device is generated by means of a 10-turn potentiometer 22, which Or is mounted on the output shaft 14a. Fig. 2). The voltage from the potentiometer 22 is counteracted by the voltage from a input potentiometer generally designated 23. The potentiometer 23 is selectively installed in accordance with the numerical value of the desired position of the control device, as will be described in the following. The output shaft of the shaft dance 14a also drives via a chain transmission 25 a tachometer generator 24, the output voltage of which is fed to the input terminals 26 (Fig. 4).

Both potentiometers 22, 23 and tachometer generator 24 are supplied with the same AC voltage. The error or correction signal; as Or proportional to the difference between. the voltages obtained by the Iran potentiometers 22, 23 are supplied to line 28 and combined with the output of the tachometer generator on line 26 after it has passed through a bridge coupling 27. The similarly composed signal is fed to a two-stage amplifier 29, 30, and the amplified signal is mixed or biased with a reference alternating voltage appearing on line 31, obtained in Iran from the same alternating voltage source which supplies the potentiometers 22, 23. The thus mixed signal is supplied to a cathode follower 32 and then to a rectifying diode 33. The rectified voltage is smoothed and supplied to the control grid in two. pentodes 34, 35.

The shaft bias voltage on line 31 is 11111110- Above a cathode follower 36, rectified by a diode 37 and smoothed, after which the thus smoothed bias voltage is printed over two series-connected potentiometers 38, 40. Potentiometers 38, 40 sliding contacts and 42. Each of the pentodes 34 and 41 Or connected in series with a working coil for a relay 43, which controls the movement of the control device in the forward direction. Relay 43 has two. differential wound work coils. Similarly, each of the pentodes 35 and 42 is connected in series with one working coil for a similar relay 44, which controls the movement of the control device in the backward direction.

When the control device is in approximately correct position, which is installed with the input of the input potentiometer 23, the voltage printed on the control of the pentodes 34, 35 has a value between the voltages of the potentiometers 38 and 40 res-p. sliding contacts, due to the reference voltage on the conductor 31. Under these conditions Or the current passing through the pentode 41 is on the current passing through the pentode 34, the relay 43 occupying and retaining in the fringe stroke. At the same time, the current through the pentode 35 is greater than the current through the pentode 42, wherefore the upper rehlet 44 occupies its envelope position. If the control device occupies a layer just behind the layer installed with the potentiometer 23, the voltage on the pentodes 34, 35 exceeds the voltage from the potentiometer 38; As a result, the current through the pentode 34 is stronger than the current through the pentode 41, so that the furnace 43 is thrown back to its on, whereby the motor. 14 (Fig. 1) is started in the forward direction. On the other hand, the current through the pentode 35 is still stronger. If the control device takes a layer in front of the layer installed with the potentiometer 23, the voltage acting on the pit pentodes 34, 35 becomes weaker on the voltage emitted by the potentiometer 40, so that the current through the pentode 42 becomes stronger than the current through the pentode 35 and the relay 44 is thrown to its so that the motor 14 is started and drives the control device in the hooked direction. Rekiet 43, on the other hand, remains French.

The motor 14 is a hydraulic motor, and the relays 43, 44 operate valves, which in turn regulate the forward and reverse movements of the motor.

Figures 3A, 3B and 3C are separate from the electrical device for insulating the input potential 23 (Fig. 4). The device comprises a motor-driven rotary selector with unidirectional movement of the type of the English Post Office, which is shown in two parts in Figs. 3B and 3C, these figures being intended to be read with the former placed vertically over the latter. The stator of the rotary selector is shown widely in the plane and the different contact fields are shown as different columns and the selector arms are shown below the stator in Fig. 3C. The connections to the selector arms are shown for simplicity at the upper end of the stator in Fig. 3B and are denoted WI-- WIG. Further displayed. it sat, on which the field contacts were interconnected. Finally, the contacts in the cases cooperating with vOl- jW8W12 are connected diagonally, the second contact in field 12 Or connected to the first contact in field 11, to the third contact in field 12 Or connected to the second contact in field 11 and to the first contact 1 in the field 10, the fourth contact in the field 12 Or connected to the third contact in the field 11 and to the second contact in the field 10 and to the first contact in the field 9 and so on.

The device according to Figs. 3A, 3B and 3C causes the control device to move backwards in certain steps of 1, 2, 3 or 4 units of length (vatic unit of length can, for example, be 25 mm by depressing a corresponding pushbutton 51, 52, 53 and 54. Furthermore, the control device can be reset after the usual rearward movement by light-weight installation of a rotatable Aiotals switch 55 and a rotatable entalsonic switch 56 and by pressing a reset button RB.

If one considers the maneuvering of the control device to one by installing the switches 55, 50 installed, or first to mark, all the selector arms of the motor rotary selector are normally kept stationary by the selector quick-acting relay HS receiving on current through the closed contacts TI. When the rb button RB is pressed, the relay B energizes and throws the contacts R3, so that the relay HS is disconnected from the contacts T1 and the relay HS in the stable is connected to the line 57, which leads to the selector arms W5, W6. The relay HS is de-energized and reverses its contacts HS1, whereby the relay T is disconnected and a hall circuit for the relay R is established through the closed contacts R2. When the relay HS is energized, the rotary selector of the rotary selector (not shown) passes current through the contacts HS1 and the line 59, and the movement of the motorized selector continues until the relay HS Ater is turned on. This occurs when the arms of the selector have been stepped up to a position corresponding to the installation of the switches 55, 56, the fixed contacts of which are optionally connected to the selector contacts in cases W5, W6 and W1 in the manner indicated in Figs. 3B, 3C. SMunda Or the switch's 55 contact »0» connected to the first ten contacts OTA in field W5, while the contact »b Or connected to the ten subsequent contacts 1TA in the same field, etc. The contact layers in field 1 have been numbered corresponding to the number of the fixed contact in switch 56, to which they are connected.

As the arms of the rotary selector have gradually moved to a position in which the contact in field 5 or field 6 is connected to the selected contact in switch 55 and the contact in field 1 or connected to the selected contact in switch 56, a circuit Iran is closed on fed the positive pawl 58 (Fig. 3A) of the current source through the selector arm W1 (Fig. 3B), the fixed contact in the case in question, the switch 56, the switch 55, the connected contact in fait 5 or field 6, the selector arm W5 or WO, the line 57, the closed contacts R3 and the fast-acting relay HS to the negative pole 60 (50 volts) negative pole 60. The fast-acting relay HS is thus energized, so that the contacts HS1 are reversed and prevented, further progress of the rotary selector, relay T is renewed, relay R turns off and the hall circuit for the relay HS is re-established through the contacts R3.

The layer in which the arms of the rotary selector stay determines the install fling of the potentiometer 23. In the present case, this potentiometer consists of two chains of resistor 61, which are connected in series over the cranial cranial shell and each consists of eight resistors with in turn the resistance values 10, 20, 30, 40, 100, 200, 300 and 300 ohms. The resistors in the first chain can each be short-circuited by the contacts AU1-DU1 and AT1-DT1, which are operated by the relays AU, BU, GU, DU, AT, BT, CT and DT. Similarly, the resistors in the second chain can be short-circuited separately by closing the contacts AU2-DU2 and AT2-DT2, which are operated by the same relays as the previous contacts. The contacts for the first resistance chain Oro normally open while the short-circuit contacts for the second resistance chain normally Oro closed; consequently, the total resistance of the hada resistance chains remains unchanged at strike-up resp. fringes of any of the relays. The relays AU-DU selectively receive on-current through a diode unit 62 via the lines 63, which Oro designated in accordance with the singular value one wishes to select, and which Oro are connected to the correspondingly numbered contacts in the rotary selector field 1. On similar sat receive the relays AT-DT selective switch-on current through a second diode unit 64 via nine lines 65, - as aro. numbered 1T-9T in accordance with the decimal value to be eliminated, and which concerns are associated with the contacts numbered on the corresponding salt in the second and third constituency fields. When the selector arms are in a prescribed position on the rotary selector, the AU-DT relays are selectively switched on to release7. IA a a voltage at the connection point mcl, lan de hada resistance chains in dependent air selector arms lag. For example, if a movement of 22 units of length has been selected by pressing the switches 55 and 56 and the reset button RB has been pressed, the selector arms will stop in the team denoted by 66 in the selector diagram and with the selector arm W2 in contact with the contact in layer 66 in the selector field 2; selector arm W3 Or as well as selector arm W2 unipolar and thus jokes in contact with flagon air the specified contacts. A circuit is closed Hrvid frau the positive pole 58, through the selector arm W1, the contact »2» in field 1 in the team 66, the air lines 63 denoted by »2» and the relay BU to the necrative pole 67. Another circuit is closed ° frail the positive pole 58, through the selector arm W2, the contact in the selector field 2, the line 2T and relact BT to the negative pole 67. As a result, the contacts BU1 and BT1 are closed and the contacts BU2 and BT2 are opened, whereby the potential 1 of the resistance chains. midpoint forOther & with an amount, which iii proportional to 22.

Relay T normally has closed contacts T2. and the fire R normally has open contacts R1, which are connected in parallel between the common connection point of the resistors 38 and 40 (Fig. 4) and the control grids of the pentodes 34, 35. When the air contact pairs T2 and R1 are closed, the grid recess on the pentodes 34, 35 loads and prevents commissioning of the motor 14 (Fig. 1). By pressing the pushbutton RB, the relay R switches on, so that the motor 14 is deactivated, until. potentiometer 23 has been converted to its new layer and relay R ater has switched off. In this way, the control device is prevented from attempting to follow the changes in the potentiometer's resistance during installation of this potentiometer. To the control of the control device, with the aid of the pushbuttons 51-54, it is first noticed that the control circuit for the relay T is broken when the flag of these buttons is depressed. The fire T thus separates from itself and closes its contacts T2, so that the grid voltages of the pentodes 34, 35 are blocked on the salt indicated above. Reliiet HS bibelralles the strike through contacts A2 — E2, but contacts Ti are opened p5. shown, connect the connectors A1-E1 to the positive pole 58. By pressing the pushbutton, the positive pole 58 was also connected to one of the yellow arms W9-W12. Suppose e.g. that the pushbutton 52, which corresponds to a movement of 2 units of length U. ex. 5 cm), is pressed down, and that the selector arms for the full press of this button occupy layer 66. The diagonal connection 68 then strains through the closed contacts of the button 52, the selector frame W10 orb the contact in the selector field 10 layer 66. The diagonal connections Concerns in consecutive groups group denoted in order a, b, c, d orh e, sh. as shown in Fig. 3B orh. 3C, all the compounds denoted by a being connected through the line 70 Oro connected to the relay A. On the corresponding salt Oro all those with b resp. c resp. d resp. e denoted the color connections by similar lines, 70 are connected by corresponding lines b reap. e resp. d resp. In the present example, therefore, a positive potential will be transmitted through the diagonal connection 68 to the relay A, which turns to ° th, the contact A1 closes, through which a hall circuit for the relay A slides past the line 70 to the diagonal connection 68. At the same time the contacts A2 are opened, so that relaet HS becomes strOmlOst. Like forul, the -wheel arms move stepwise from Over the contact field, until the rapid fire HS again gets current; delta intraffar, when the selector arm W8 connects to a fait contact, which Mlles positiy through the contacts A1 and the line 70 connected thereto. Salunda the selector arms come to move two steps, so that the Valjaranuen W8 arrives at the contact in the felt 8, which is connected Tiled the diagonal obstruction 68. DO relay HS salunda ater gets current, it reverses its contacts HS1, varigenour relay T gets current and establishes a hall circuit for reldet HS through its contacts TI. At the same time, relay A is de-energized by closing contacts Ti. As can be seen from some of the foregoing, the movement of the selector arms Iva caused a reversal of the connections to the diode units 62, 64 and the selective operation of the contacts AU1 — DT1 and AU2 — DT2, so that the control device is moved backwards by two units of length cm.

The same operation is performed if in the stable the flag of the pushbuttons 51, 53 and 54 is pressed down. On the other hand, the number of steps that the rotary selector arms perform varies from case to case depending on which of the selector arms W9, W11 and W12 sour slides manOverstrommen.

The step-by-step installation of the control unit by selective connection of the selector arms W9 — W12 can alternatively be maneuvered with the aid of a widbar switch 71. DO this switch is rotated from the team;> FRAY> example to the team for 2 longitudinal movements (5 cm), and the contacts If S, S2, P1, P2 are reversed, one of the lines will receive current, so that the mechanism is started in the manner described and the control unit is moved backwards 2 units (5 cm). The contacts S1, S2, P1 and P2 cannot be in maneuvers maneuvered by the forging press, so that the movement of the control device Or is linked or synchronized with the press.

For maneuvering the vertical movement of the gripper shaft 17, a contributory cylindrical piston device 72 for raising and lowering the wrought iron forms a continuously acting servo system, the piston movement of which is proportional to its control valve movement, a direct connection between the coal or the control valve slide forming a return connection.

The control valve slide Or is connected to an electric motor 73 by a nut 74 of the nut orb screw type, and this motor is operated by means of an on- and off-switching electrical system similar to those previously described. In the present case, voltage dividers are used for layer installation and layer detection. Varjanite does not show electronically operated relays to determine the direction of rotation of the electric motor. This motor in turn displaces the control valve slide, whereby the slide movements following the piston raise or forge the forging.

The voltage divider 75 for the layer detection is rotated by means of a rack shaft from the hydraulic piston, and the input voltage divider Or is calibrated in a length of 0 to 20 cm (the lifting distance). A ride of the input voltage divider is accompanied by a corresponding movement of the control device. A tachometer generator (Hie shown) Or via a gear connected to the electric motor may all generate a feedback signal dependent on the motion resistance. Accurate bites Or approximately ± 1.6 mai on the entire lylist track 20 cm can be traversed in 2 seconds.

The path for vertical movement is ulgiires by a simple manually rotatable voltage divider. The error or correction signal used to operate the actuator is explained by the voltage difference between the push contact of the input voltage divider and the push contact of a similar voltage divider as connected to the hydraulic cylinder or piston device for vertical movement.

The gripper shaft 17 can be rotated by means of a hydraulic motor 76 (Fig. 1) while forming a gear shaft 77 and a (tanned co-acting, ride the gripper shaft fixed gear 78. The gear 78 is in engagement with a gear 80 pit shaft to a self-driving motor 81, which Oven drives a tachometer generator 79. 1137 508 - The hydraulic motor 76 is operated by means of solenoid-driven solenoid valves, which in turn are maneuvered by relays similar to relays 43 and 44 in Fig. 4. The maneuvering of these relays takes place by means of a seal generator 82 (Fig. 5), the output voltage of which depends on the angular difference between its rotor and the seal of the seal assembly 81 and is fed to the connection terminal 28 in a coupling substantially similar to Fig. 4, but without the contacts T2 and R1. salt as questioning the maneuverability of the longitudinal movement, and then the error or correction signal, which represents a difference in angular position between the cell vision receiver 81 and the cell signal sensor 82 , falls outside the area set by the potentiometers 38, 40, the fire 43 or 44 turns on, so that the hydraulic motor 76 (fig. 1) is made to turn the gripper, until the error between the hadel sighting machines has decreased to approximately zero.

As shown schematically in Fig. 6, as well as the cell oxygen generator 81 as the cell generator 82, a single-phase rotor winding 81a and 11a, respectively. 82a and a three-phase delta-connected stator winding 81b resp. 82b. In addition, there is a differential self-aligning machine 90 with three-phase stator and rotor windings 90a, 90b. The rotor of the vision machine 90 can be rotated relative to the stator by means of a rotatable knob 91. The rotor winding 81a is connected to the reference AC head, the windings 81h and 90a are connected on the shown salt, as are the windings 90b and 82b, and the stator winding 82a is connected to the line 28a. (Fig. 4). The gripper output is installed by turning the knob 91; then the gripper can be rotated in only one direction prescribed angles with the aid of the coupling device according to Fig. 5.

The device according to Fig. 5 is so shaped that it rotates the self-sighting machine 82, and claimed the gripper 17, which is raised by a number of given angles, which in the present examples are 90 °, 45 °, 22 1/20 and 15 °. The shaft of the selenium sensor 82 is provided with a gear 83, which is driven by an electromagnetic step feeding device, which is indicated at 84. This step feeding device 84 rotates the gear 83 an angle equal to a tooth pitch for each time the driving solenoid Y is supplied with a current pulse. This rotation of the air gear 88 corresponds to a rotation of the gripper 17 at an angle of 3 1/4 °.

The solenoid Y is supplied with the required number of step supply pulses for rotating the gripper 17 the intended angle of rotation by means of a rotary selector with unidirectional movement, the various contact fields of which are denoted Z1 - Z7, while its drive coil is denoted by Z and its switch contacts by IC.

The angle of rotation of the gripper 17 is installed by rotating a multi-pole rotary switch with 4 contact members, the poles of which are denoted SW1 — SW2, SW3 and SW4. When the switch SW is installed in its first contact layer shown to select a rotation angle of 15 ° and the pushbutton PB is pressed, the firing P turns on current and opens its edge contacts P1. Before the contacts P1 are opened, however, a circuit is closed from the positive pole 85 by the pushbutton PB, the contacts P1, the contact device SW1, SW2, the coil Z of the selector and the switch contacts IC to the negative pole 86 of the supply current source. In the hada folds Z1; Z2, which were connected in parallel, drew all the contacts with the exception of every fourth connected. Thus, the first rotation of the selector involves one step, that the selector arm for the contact fields Z1, Z2 receives current from the positive pole 85 and closes the strain circuit through the pole Z and the contacts IC. As a result, the solenoid Y, which through the contact device 8W3 and the contact field Z3 Or connected in series with the contact arms for the cases Z1, Z2 and the switch contacts IC, will be supplied with four pulses, whereby the seal device is rotated an angle equal to four teeth of the sprocket 83, i.e. 13 °. After the rotary selector_ has been rotated four steps, the selector arms of the field Z1, Z2 are located on a contact which is not in connection with the pole 85 of the tension ball, for which reason the rotation of the selenium generator 82 ceases.

When the switch SW is installed in any of the three other contact layers, ie. corresponding to the angles 22 1/2 °, 45 ° resp. 90 °, obtain the coil Z and the contacts IC step supply pulses from the pawl 85 pawl through the pushbutton PB, the contacts P1, the contact device SW1, a line 87, the first contact in the selector field Z7, and the contact device SW2. The selector is rotated one step, and as the other contacts in the field Z7 are connected to the pawl 85 of the supply current source, the selector continues to move gradually over separate contacts, until it has returned to the first contact. The solenoid Y Or through the contact device SW3 connected to the selector arms for the contact fields Z4, Z5, Z6. In the field Z4 are the second to oeh with the seventh contact. connected to the contact device SW4, so that six pulses through the selector. field Z4 is supplied with the solenoid Y da. the switch SW is installed in the layer for 22 1/2 °, whereby the seal generator 82 is rotated 19 1/2 °. Pa. correspondingly set grille, all when the switch SW is installed in the layer for 45 ° resp. made for 900, 12 resp. 21 pulses are applied to the solenoid Y, whereby the cell generator is rotated 45 ° resp. 90 °.

The various movements of the control device described above can be synchronized with each other and with the forging press in order to achieve as efficient use of time and equipment as possible. The interval between successive types of work of the press should not be longer than that required for the control apparatus, and as the time for the injection becomes shorter during automatic operation, it becomes increasingly important to obtain as short waiting times as possible between a transfer and nasta.

Salunda states, for example, that in the case of manual initiation of each movement a forceps movement would probably not be initiated before the press head began its lifting movement after a work stroke, while, due to the time required to start the control device, its longitudinal movement could in fact be started already. yid the end of the downward pressure battle so that no time would go farlorad. In addition, it is sometimes necessary to perform both longitudinal motion and rotational motion at the same time, whereby the timing or time control problem becomes even more syarhemastrated.

A serial program control of the various movements may involve that habitual movement was initiated by the previous movement or also that the movements or maneuvers are started and completed completely independently of each other according to a fixed schedule.

In the case where each maneuver is automatically started by the previous maneuver, the press and the maneuvers for longitudinal movements and for rotational movements are interconnected by automatic follow-up coupling, the method consisting in using the relays which control a movement or maneuver to start resting motion. or maneuver. At the end of the return stroke, the forging press is thus struck, for example, a relay is added to initiate the downward working stroke, even though the press head does not move until a short time interval later. This rela contacts Concerns connected in parallel with the start button. for the rotational movement and longitudinal movement, so that each stroke of the forging press achieves a step of longitudinal movement and a step of rotation, which in turn results in a helical machining program during forging. Donna technology Or suitable for forging round goods. Either of these movements can of course be removed, if it is taken into account.

In the case where each movement was initiated in accordance with a time schedule, program control is obtained by means of a cam-driven contact device for starting each of the controlled movements, the camshafts being driven on a common axis with a constant rotational speed, which is installable and salunda can be changed as needed. Each movement is performed once for each full rotation vary of the cam discs, and by setting the contactors in the appropriate inboard layers, the various actuators are actuated at the intended inboard times. The speed at which the cam discs rotate is determined by the rate in Aitken. the various steps of the maneuvering process must be repeated. In some cases it is desirable that the time interval between maneuvers should be kept constant with varying speed of the program switch, and delta can be achieved by coupling the layer setting means thereof to the speed control. Once the instantaneous time relation has been heard by means of, for example, the return stroke of the press or the longitudinal movement of the control device, a change in the number of working strokes per minute in the forging press does not greatly coordinate the movements.
