Belt wheel extrusion-spinning near-net forming device

Abstract

The invention provides a belt wheel extrusion-spinning near-net forming device. The belt wheel extrusion-spinning near-net forming device comprises a base. Extrusion piston rods of extrusion hydraulic cylinders on the two sides of the base are connected with extrusion rods, the extrusion rods are matched with belt wheel connecting shafts, the belt wheel connecting shafts are connected with driven belt pulleys, the driven belt pulleys are connected with driving belt pulleys connected to a rotary shaft, the rotary shaft is connected with a servo motor, the ends of the extrusion rods are connected with extrusion dies, and the two extrusion dies axially clamp a workpiece blank. The base is connected with spinning supports, spinning hydraulic cylinders are evenly distributed on the spinning supports along the circumference, spinning piston rods of the spinning hydraulic cylinders are connected with spinning connecting frames, the spinning connecting frames are connected with sliding blocks, the sliding blocks are matched with sliding rails fixed to the spinning supports, the spinning connecting frames are connected with spinning dies through spinning die fixing seats, and the spinning dies are radially matched with the workpiece blank. Through cooperation of spinning and extrusion, near-net forming is conducted on a belt wheel, and the belt wheel extrusion-spinning near-net forming device has the advantages of being high in machining efficiency, low in blank requirement, high in machining accuracy and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical forming presses, in particular to a pulley extrusion-spinning near-net forming equipment. Background technique [0002] As an important mechanical transmission part, pulleys processed by traditional processing methods can no longer meet people's demand for high performance. As a result, people have been exploring how to improve the structure of pulleys and corresponding processing methods for many years. With the research and development of new technologies, the level of spinning technology has also been improved accordingly. Aluminum spinning pulleys are being widely used in automobiles and other industries due to their advantages of high precision, energy saving, material saving, less cutting, and environmental protection. , Casting machine processing pulleys, stamping bulging pulleys, stamping welding pulleys have broad application prospects, but the traditional spinning pulley process can o...

AI Technical Summary

Problems solved by technology

The assembly process greatly increases the complexity of the pulley manufacturing, and also puts forward higher requirements for the machining accuracy of the hub and rim

There is a certain gap in the assembled pulley, which makes the force on the pulley uneven and the dynamic balance is poor, which affects the service life of the pulley
