Abstract

The invention relates to a pneumatic type controllable radial impact precision blanking machine for metal bar and tube materials. The pneumatic type controllable radial impact precision blanking machine comprises a metal bar and tube material clamping device, a power transmission device and a load application device. The metal bar and tube material clamping device comprises a bar and tube material sleeve used for fixing the metal bar and tube materials. The power transmission device comprises an alternating current servo motor and a revolving connecting plate driven by the alternating current servo motor. The load application device comprises a rotary cylinder which is connected to the revolving connecting plate and is of a symmetrical structure. The alternating current servo motor is used for driving the rotary cylinder of the symmetrical structure, so that loading is carried out in the circumferential direction of the metal bar and tube materials in a certain load sequence, and precision blanking of the metal bar and tube materials is finished under the cyclic action of bending moment loads. By adjusting the rotation angle and rotation speed of the alternating current servo motor and the air inlet and outlet sequence and air inlet amount of the rotary cylinder, an impact hammer in the rotary cylinder can accurately and rapidly apply constant amplitude impact loads to the specific loading position. The whole pneumatic type controllable radial impact precision blanking machine for the metal bar and tube materials has the advantages of being simple in structure, good in stability, high in controllability and the like.

Description

technical field

[0001] The invention belongs to the technical field of processing and forming equipment for metal rods and tubes, and relates to a pneumatic controllable radial impact metal rods and tubes precision blanking machine. Background technique

[0002] As the beginning of the parts processing process, the metal rod tube is also the starting point of the entire industrial machine production, and its blank is one of the most basic blank forms in the industrial production process. Under normal circumstances, the production of various shaft blanks requires a blanking process as a material preparation process. The blanking of metal rods and tubes refers to the separation of metal rods and tubes produced by metal products factories into subsequent cutting or non-cutting processes. A material preparation process for blanks of different lengths will directly affect the processing quality, cost and efficiency of subsequent parts and even the entire machine on the section qu...
