Abstract

The invention discloses a combined necking and inward turning spinning machine, and belongs to the technical field of spinning forming. A rack (1) is included, and a workpiece clamping device (2) and a necking, spinning and inward turning device (3) which are opposite to each other are arranged on the rack (1). The necking, spinning and inward turning device (3) comprises a spinning necking mechanism and a spinning and inward turning mechanism, and a first driving device (4) and a second driving device are further arranged on the rack (1). An automatic feeding device (5) is arranged on one side of the necking, spinning and inward turning device (3). A first spinning roller (6) with an arc-shaped groove is adopted to conduct spinning necking on the end portion of one end of a workpiece, a second spinning roller (20) is arranged in a first rotating shaft (8) to conduct spinning and inward turning on the workpiece subjected to necking, necking and inward turning of the end portion of the workpiece are completed in the same spinning machine, the workpiece with a double-layer annular pipeline is machined, the joints of the end portions of the double-layer pipeline are in seamless connection, and the workpiece machining precision and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of spinning forming, and in particular relates to a combined shrinking and turning inward spinning machine for necking and turning inward at the end of a workpiece. Background technique [0002] Spinning is to fix the flat or hollow blank on the mold of the spinning machine. While the blank is rotating with the main shaft of the machine, the blank is pressed with a spinning wheel or a driving rod to cause local plastic deformation. It is a special method. Forming method, the spinning method can be used to complete the processes of deep drawing, flanging, shrinking, bulging and curling of rotating bodies of various shapes. With the advancement of technology and the needs of people's processing and use, the shape requirements of parts processed by spinning are getting higher and higher. In the field of mechanical processing, there is a processing requirement for shrinking the end of the workpiece. Necking and...
