Abstract

The invention discloses a single-point incremental forming processing device for a tubular part. The single-point incremental forming processing device comprises a clamping and rotating mechanism, a feeding mechanism and a control device, wherein the feeding mechanism comprises a second stepping motor, a transmission lead screw, a support, a third stepping motor, a sliding mechanism and a formingtool head; the second stepping motor is connected with the transmission lead screw; the two ends of the transmission lead screw are supported by the support; the axial direction of the transmission lead screw is parallel to the axial direction of a transmission shaft, and the transmission lead screw is used for driving a sliding mechanism to move in the axial direction of the transmission lead screw; the sliding mechanism is arranged on the transmission lead screw, and the second stepping motor is connected with the sliding mechanism and used for driving the sliding mechanism to move in the radial direction of the transmission lead screw; the forming tool head is installed on the sliding mechanism, and the feeding movement of the forming tool head is realized under the driving of the sliding mechanism. The single-point incremental forming processing device has the advantages of being low in manufacturing cost, wide in application range and high in production speed.

Description

technical field [0001] The invention belongs to the field of single-point progressive forming, in particular to a single-point progressive forming processing device for tubular parts. Background technique [0002] Metal single-point incremental forming technology is a new processing technology. It is an advanced manufacturing technology based on computer technology, numerical control technology and plastic forming technology. It belongs to the moldless rapid prototyping process. It uses numerical control equipment and simple auxiliary devices to shape the workpiece point by point with a pre-programmed numerical control program. With the gradual accumulation of local plastic strain, the predetermined shape of the part is finally obtained. It can not only form some formed parts with complex shapes, which cannot be formed by traditional molds, and small batches, but also can be used in the sample trial production stage before the production of large-scale stamping parts, and us...
