Automatic feeding and discharging equipment for swelling pressure forming of automobile axle housing pipe fittings

Abstract

The invention discloses automatic feeding and discharging equipment for swelling pressure forming of automobile axle housing pipe fittings. A workpiece grabbing device of the feeding and discharging equipment is used for picking and placing workpieces from the inside of a material rack or a mold through V-shaped electromagnetic blocks I and II (1 and 1') on straight arms I and II (2 and 2') of the grabbing device. A vertical cylinder (5) pushes the workpiece grabbing device to move up and down in the vertical direction. A servo motor I (15) drives the grabbing device to rotate within the theta angle range of the vertical plane so that liquid in the pipe fittings can be poured out. A servo motor II (17a) drives a revolving platform (17) to rotate so that the grabbing device can be driven to rotate around the vertical axis within the horizontal plane. A longitudinal moving station (19) drives the grabbing device to move front and back through a longitudinal cylinder (24). By means of the automatic feeding and discharging equipment, the workpieces can be picked and placed accurately, and liquid in the workpieces can be poured out completely. Moreover, the workpieces can be placed at the specified positions of the next procedure in opposite directions. The automatic feeding and discharging equipment is simple in structure, convenient to operate, low in processing cost and capable of improving production efficiency obviously.

Description

[0001] Technical field [0002] The invention relates to an automatic loading and unloading device for pipe parts, in particular to an automatic loading and unloading device for pipe parts used in a production line of expansion and compression forming automobile axle housings. Background technique [0003] The automobile axle housing is an important load-bearing and force-transmitting part of the automobile. It has large geometric size, complex shape and heavy weight (the weight of the medium-sized axle housing is about 40kg, and the weight of the heavy-duty axle housing is more than 100kg). It belongs to the large-size variable diameter complex pipe fitting. figure 1 Shown is an automobile axle housing tube, the middle part is a spherical bulging bridge bag, and the straight arm parts on both sides are round tubes. The expansion and compression forming process of the automobile axle housing needs to reduce the diameter of both ends of the selected initial tube blank of a cert...
