Abstract

The invention relates to a synchronous circle shaping device for a cylindrical work-piece and belongs to the field of work-piece shaping. The synchronous circle shaping device for the cylindrical work-piece comprises a supporting cylinder, a left end cover, an air cylinder body, a piston, an expansion body, a supporting rod, supporting heads, a radial reset spring, a right end cover, an expansion rod, a guide rod and an axial reset spring. An air compressing device is used for inflating the air cylinder body so that the piston can drive the expansion rod to move right together. The expansion rod pushes all separated parts of the expansion body to synchronously expand outwards in the radial direction through matched conical surfaces among inner holes of combined parts of the expansion body. The arc surfaces of all the supporting heads connected to the outer ends of all the separated parts of the expansion body are used for synchronously shaping the inner wall of the cylindrical work-piece to be shaped. According to the circle shaping device, synchronous perfect circle shaping is carried out on the thin-wall cylindrical work-piece, the shaping efficiency is high, the shaping quality is good, and the synchronous circle shaping device has high application and popularization value.

Description

technical field [0001] The invention relates to a synchronous rounding device for cylindrical parts, which belongs to the field of workpiece shaping. Background technique [0002] The mouth of existing thin-walled cylindrical parts will be deformed after processing, resulting in different values ​​of the diameter of the cylindrical part when measured at different angles of the circumference. When two cylindrical parts with the same diameter are butt welded Yes, welding cannot be performed. In order to solve this problem, the traditional process usually uses manual methods to round the deformed part by hammering it. This method has low shaping efficiency, and the shaping is greatly affected by human factors. The shaping quality cannot meet the design requirements and cannot adapt to batch production. chemical production. Contents of the invention [0003] The object of the present invention is to provide a synchronous rounding device for cylindrical parts in order to solv...
