Detailed ways

As shown in the accompanying drawings, the utility model includes an active forming device and a driven extrusion forming device,

The active forming device includes a frame 1 and a set of rollers 2 arranged on the base,

There is an arc-shaped groove on the top of the frame 1, and the two ends of the idler roller 2 are respectively fixed with rotating shafts. A group of idler rollers 2 are arranged in sequence along the arc-shaped surface of the top of the rack 1, and the rotating shafts at both ends of a group of idler rollers 2 pass through the The bearings are movably installed on the frame 1, and double-row sprockets 3 are arranged on the rotating shafts at both ends of the idler 2, and each adjacent two double-row sprockets 3 are connected by a chain 4 transmission, and the motor 5 and the deceleration The machine drives one of the double sprockets 3 to rotate,

The driven extrusion forming device includes a set of guide columns 6 arranged on the base, an oil cylinder supporting the top plate 7, a hydraulic cylinder 8 and a driven pressing assembly,

The oil cylinder support top plate 7 is fixedly installed on the top of a group of guide columns 6, and the hydraulic cylinder 8 is installed on the oil cylinder support top plate 7,

The driven pressing assembly includes a set of driven rollers 10, a force plate 11 and a pair of side plates 12,

The four corners of the force plate 11 are respectively provided with guide holes, and are movably installed on a group of guide columns 6 through the guide holes. The force plate 11 is located under the cylinder support top plate 7 and is fixedly connected with the power output shaft of the hydraulic cylinder 8. The bottom of the plate 12 is arc-shaped, and a pair of side plates 12 are symmetrically distributed and fixedly installed on the bottom surface of the force plate 11.
