Circumferential feeding device for cross wedge rolling

Abstract

The invention relates to the technical field of metal plastic forming technology and equipment, and provides a circumferential direction feeding device for cross wedge rolling, comprising a feeding unit and an arc-shaped slide rail; the feeding unit includes a feeding groove and a feeding plate, and the feeding groove Preferably, it is directly opened on the roll of the cross wedge rolling mill, which can reduce the width of the splicing plate; the splicing plate is welded on the roller shaft and is guaranteed to be tangent to the bottom of the splicing groove, which is convenient for the placement of the blank; the front end of the splicing plate has A small arc is used to ensure the safety of loading, and the width of the feeding plate should avoid collision with the guide plate at the lower point. The arc-shaped slide rail is composed of two tangent arcs, which can make the billet slide smoothly to the lower roller. The device of the invention is a non-continuous feeding device, that is, each time the rolling is completed, the rolls must stop at the feeding position to complete the next charging and then rolling, which is especially suitable for feeding large shafts; device structure Simple, good stability, convenient feeding, saves the space of the equipment, and has broad application prospects.

Description

Technical field [0001] The present invention relates to the field of metal plastic forming processes and equipment, and more particularly to a wedge-raised rolled circular direction feed device. Background technique [0002] Large axis parts are one of the key components of major equipment, and the power transfer and motion implementation of large equipment. It is generally the role of composite load such as bending, twisted, impact and vibration under high-speed overload conditions, its production cost, forming accuracy, and performance quality will directly affect aerospace, rail transit, heavy machinery, military equipment and other industries. Key equipment performance is the premise of developing large-scale advanced equipment manufacturing. The wedge process has the advantages of high production efficiency, high material utilization, and stability of material utilization, and has a wide range of applications in the production of shaft parts. [0003] At present, the feed mo...

Problems solved by technology

In the axial feeding, the blank is pushed into the mold by the push rod of the cylinder, and then rolled. Since the length of the billet of the large shaft is mostly more than 2000mm, it will undoubtedly increase the length of the push rod and require greater thrust. This also increases the length of the overall equipment and the difficulty of feeding
