    1483646 Mechanical presses AIDA ENG KK and ZAIDAN HOJIN KIKAI SHINKO KYOKAI 14 Aug 1974 [18 Aug 1973] 35738/74 Heading B5F [Also in Divisions B3 and G3] The down position of a press-slide 5 in a stamping, punching or bending &c. press is adjusted by a worm gear 5, 5<SP>1</SP> driven, through a clutch A, by a motor 22, the clutch slipping when a pre-determined load is applied to the slide, an additional pre-load being applied when the motor is controlled in response to a comparison between a pre-set pulse count and a pulse count obtained by a rotary pulse generator 25 driven by the worm. As shown, an oil motor 22 drives, through gears 20, 9, 16 and a chain 8, the worm gears 5, 5<SP>1</SP> which engage worm nuts 3, 3<SP>1</SP> on screwthreaded shafts 1, 1<SP>1</SP>. With the slide at its bottom dead centre and a suitable spacer between dies in the press, motor 22 is run to pre-load the slide with the clutch A slips The gear 16 forming the central element by the clutch is loaded by a piston (15), Fig. 2 (not shown), operated by compressedair. To apply the additional pre-load and compensate for tensile effects the slide is first raised from the bottom position by the main motor of the press. A desired pulse count is now set in a memory 31, Fig. 3, and the motor 22 again run. Pulses from the generator 25 are fed to a counter 32 and then to a comparator 33 where they are compared with the pre-set count from the memory 31. A comparison signal is fed to an amplifier 35 controlling a servo valve 36 between an electromagnetic valve 37 and the motor 22. A discriminator 30 is connected to the comparator 33 and the valve 37 to control the direction of rotation. An adjustment indicator 27 is driven by a gear 24, 28 from the worm gear 51.

    专利说明:

    The invention relates to the processing of metals by pressure, in particular, to devices for adjusting the closed height of the press. A known device for adjusting the closed height of the press, comprising screws mounted in the slider, which are screwed onto worm gears which engage with screws, the first of which is associated with the drive and connected to the second screw. . A disadvantage of this device is that when adjusting the closed height of the press, the gaps and the amount of deformation of the bed are not taken into consideration. The purpose of the invention is to compensate for the deformation of the frame when installing the strain. a pneumatic friction clutch of the torque limit is installed on the intermediate shaft of the multi-gear gear drive. In addition, the control system is driven in the form of a rotating pulse generator, mechanically connected with the shaft of the second screw and electrically connected by means of a comparison unit with the control system. FIG. 1 shows a device for adjusting the vertical position of a press ram; in fig. 2 - torque limiting pneumatic clutch; in fig. 3 - a digital device for controlling the control, preloading the slider to compensate for the deformation of the press. The device contains screws 2 mounted on the slider 1, which are screwed with worm gears 3. and 4. The worm gears 3 and 4 are meshed with the worm shafts 5 and 6, respectively, on which the sprockets 7 and 8 are mounted, connected via an intermediate sprocket 9 with a chain 10. A gear 11 is fixed on the worm shaft 5, the rotation of which is transmitted from the motor 12 through gear; Erni 13, 14 and 15. The gear 13 is mounted movably on the shaft 16 fixed in the slide 1o The hub of gear 13 is rigidly connected to shaft 17 hydraulic motor 12, fortified th bracket 18 attached
    Screws 19 to slider 1; Gear 14 is rotatably mounted on shaft 20 mounted on slider. A gear 15 is mounted on the hub 2.1 of the gear 14, on the ends of which there are friction gaskets 22 to 23. A pneumatic cylinder is mounted on the same hub, the piston 24 of which 24 interacts with the friction gasket 23. Gear 26 is attached to the worm shaft 5 with the gear 27 of the rotating generator 28 pulses and with the gear 29 of the height indicator located on the slider 1,
    In the device control system, a command device 30 is provided in which the amount of load compensation is processed into pulses, then memorized by device 31.
    The pulses from the rotating generator 28 and the device 31 are compared in the adder 32, and the electrical signals generated by it are transmitted to the converters 33 and 34, and then amplified in the amplifier 35.
    The pulses from the rotating pulse generator 28 are summed in the adder 32, and the result of the sum is compared with the number of pulses set in the counter of converter 33. The result of the comparison between the number of pulses from the adder 32 and the set number of pulses is converted into an electrical value in the converter 33 from digital into a continuous one, from where through the converter 34 the signal enters the amplifier 35, where it is amplified to such an extent that it can be controlled by a servo valve 36.
    The command device 30 comprises a discriminator which determines the direction of movement of the slider, whereby the electrically controlled spool 37 is moved left or right. This changes the direction of rotation of the motor 12, as a result of which the ram 1 is raised or lowered.
    The rotation of the motor 12 is carried out from the pump 38.
    The device works as follows ..
    After lowering the slider 1 to the lower dead point, the hydraulic motor 12 is turned on, and at the same time air is supplied to the cylinder 2 of the pneumatic friction clutch of the limiting moment under a predetermined pressure. Rotation from the motor through gears 13, 14, 15 and 11 is transmitted to the worm shaft 6, and from it to the worm gear 3. Simultaneously from the worm shaft 6, chain 10 through sprockets 7 and 8 rotates to the worm shaft 5 and worm wheel 4 associated with it. 4. When synchronous movement of worm wheels
    wheels 3 and 4 is hoisted or
    lowering the slider 1. The angle of rotation of the screw or the stroke of the slide is recorded by a rotating pulse generator 28, the rotation of which is transmitted from the worm shaft 5 through gears 26
    and 27. The pulses from the generator 28 and the driver. 31, which is adjusted to the required compensation, is compared in the adder 32, and depending on 6t of the comparison results, through the converter 33 and the amplifier 34, the valve 36 is commanded, resulting in the hydraulic motor starting or stopping. Overload protection is provided by a pneumatic limit torque clutch.
