A processing device for single-point progressive forming of inner circle of tubular parts

Abstract

The invention discloses a single-point progressive forming machine for the inner circle of a tubular part. The single-point progressive forming machine comprises a clamping mechanism, a drive mechanism, a tool head moving mechanism and a control device. A first stepping motor is connected with a reducer. A transmission shaft is connected with the reducer. The operation of the transmission shaft is achieved under the drive of the reducer. The rotation of a gear is achieved under the drive of the transmission shaft. The rotating motion of the clamping mechanism is achieved under the effect of a transmission gear. A second stepping motor is connected with a transmission lead screw. The transmission lead screw drives a sliding mechanism to move in the axial direction of the transmission lead screw, and the sliding mechanism drives a feed mechanism to move. A third stepping motor is connected with the feed mechanism to drive a tool head bracket to move. The tool head bracket is mounted on the feed mechanism. The tool head bracket drives a tool head to move. The clamping mechanism, the drive mechanism and the tool head moving mechanism are matched during moving through the control device, the rotating motion of the clamping mechanism and the feed motion of the forming tool head are achieved, and the required part is machined. The single-point progressive forming machine has the beneficial effects of being low in manufacturing cost, wide in application range and high in production speed.

Description

Technical field [0001] The invention belongs to a dieless single-point progressive forming technology, in particular to a single-point progressive forming device for the inner circle of a tubular part. Background technique [0002] The traditional processing of pipe parts uses pipes as blanks to obtain pipes of the required shape and size through various plastic or cutting processing methods. The basic processing procedures mainly include cutting, bulging, bending, necking, flaring, crimping, etc. Each processing procedure needs to be realized by different specific methods, which is tedious and time-consuming. With the continuous development of society, the speed of product update is getting faster and faster, which requires companies to continuously shorten the product development and production cycle. Similar to traditional stamping, traditional pipe fitting processing needs to design molds according to the shape of the product, and then test molds, and then perform mold repa...
