Drawings
FIG. 1 is a schematic front view of the present invention;
fig. 2 is a schematic top view of the present invention;
in the figure: 1. the device comprises a working table plate, 2 parts of fixed blocks, 3 parts of adjusting bolts, 4 parts of wedges, 5 parts of slide block connecting plates, 6 parts of oil cylinder connecting plates, 7 parts of connecting pieces, 8 parts of oil cylinders, 9 parts of oval rear die fixing plates, 10 parts of oval rear dies, 11 parts of oval front dies, 12 parts of dovetail slide blocks, 13 parts of limiting plates and 14 parts of conical pins.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
In the figure: a manhole flange ellipse drawing machine comprises a working table plate 1, an oil cylinder 8 and a connecting piece 7, and is characterized in that: the left side and the right side of the working table board 1 are welded with fixed blocks 2, the side faces of the fixed blocks 2 are provided with a plurality of adjusting bolts 3, the inner sides of the two fixed blocks 2 are provided with wedges 4, the wedges 4 are fixed on the working table board 1 through screws, and the inner sides of the two wedges 4 are provided with dovetail slide blocks 12; a limiting plate 13 is welded in front of the working table plate 1, and an oval rear template 9 is connected with the rear of the working table plate through screws; an elliptic rear die 10 is welded on the elliptic rear template 9; the dovetail slide block is characterized in that two sides of the dovetail slide block 12 are connected with slide block connecting plates 5 through screws, an oval front die 11 is welded in the middle of the dovetail slide block 12, the rear ends of the two slide block connecting plates 5 are connected with an oil cylinder connecting plate 6 through screws, and a connecting piece 7 is arranged between the oil cylinder connecting plate 6 and an oil cylinder. A plurality of taper pins 14 are arranged between the elliptical front die 11 and the sliding block 12. A plurality of taper pins 14 are arranged between the elliptical rear die 10 and the elliptical rear die plate 9. The elliptical front mold 11 is arranged as a small semicircle. The elliptical rear mold 10 is configured as a large semicircle. The elliptical rear mold 10 and the elliptical front mold 11 are combined into a whole circle. An adjusting gap is arranged between the fixed block 2 and the wedge iron 4.
During specific implementation, a plurality of adjusting bolts and nuts are installed on the outer side of the fixing block 2, so that the gap between the dovetail sliding block and the wedge iron can be adjusted conveniently, and the dovetail sliding block can move freely. During operation, with circular flange cover in the oval back mould and the oval front mould outer lane that close as an organic whole, the hydro-cylinder passes through the hydro-cylinder connecting plate and promotes the slider connecting plate, makes oval front mould promote forward on the forked tail slider to drive the flange and produce tensile deformation forward, when contacting with the stopper, hydro-cylinder stop motion stops tensile deformation, and after the flange warp the stability, the hydro-cylinder pulls back the forked tail slider, take out oval manhole flange can.
