Abstract
A pressure welding method and a pressure welding device (1) includes a plasticizing unit (7), a compression unit (8), a machine head (13) that includes a spindle (54) and a component holder (34). The pressure welding device (1) further includes a spindle drive (56) and an actuation mechanism (41) that includes an actuation drive (65) for the component holder (34). The actuation drive (65) is placed between the spindle drive (56) and the spindle (54) within a drive train (57).
Claims15
A pressure welding device with a plasticization device comprising an upsetting device, the pressure welding device comprising:
- a machine head with a spindle;
- a component mount comprising a clamping device;
- a spindle drive;
- and
- an actuating device with an actuating drive for actuating the component mount, wherein the actuating drive is arranged in a drive train between the spindle drive and the spindle, the actuating drive having a rotatable drive housing, which is rotatingly connected to a drive shaft of the spindle drive and to the spindle and transmits drive torque, the actuating drive being configured as an electric or hydraulic drive, the actuating device having a rotary feed device for feeding operating materials comprising hydraulic fluid or electric current to the actuating drive, rotating with the spindle, from outside, for co-rotating the actuating drive, the rotatable drive housing being located between the drive shaft of the spindle drive on one side and the spindle on another side, wherein an operating position of the clamping device of the component mount is detected by a measuring device for measuring an actuating stroke or an adjusting stroke of the actuating device.
A method for pressure welding with a pressure welding device, which has a plasticization device and an upsetting device as well as a machine head with a spindle and with a component mount, as well as a spindle drive and an actuating device with an actuating drive for the component mount, the method comprising:
- arranging the actuating drive in a drive train between the spindle drive and the spindle;
- and
- actuating the component mount by the actuating drive arranged in the drive train between the spindle drive and the spindle, the actuating drive having a rotatable drive housing, which is rotatingly connected to a drive shaft of the spindle drive and to the spindle and transmits drive torque, the actuating drive being configured as an electric or hydraulic drive, wherein operating materials are fed to the actuating drive rotating with the spindle from outside by a rotary feed device arranged between the spindle drive and the machine head, the rotatable drive housing being located between the drive shaft of the spindle drive on one side and the spindle on another side, wherein an operating position of a clamping device of the component mount is detected by a measuring device for measuring an actuating stroke or an adjusting stroke of the actuating device.
