Abstract

The invention discloses a barrel flanger for an automobile pre-silencer. The barrel flanger comprises a left oil cylinder (2), a right oil cylinder (3), a left flanging mould (4) and a right flanging mould (5), wherein the left flanging mould (4) is connected with a piston rod of the left oil cylinder (2); the right flanging mould (5) is connected with a piston rod of the right oil cylinder (3); a left supporting seat (6) and a right supporting seat (7) are arranged between the left flanging mould (4) and the right flanging mould (5); the upper end of the left supporting seat (6) and the upper end of the right supporting seat (7) are respectively provided with an arc-shaped notch; the arc-shaped notch of the left supporting seat (6) corresponds to the arc-shaped notch of the right supporting seat (7) in position. By the adoption of the structure, the barrel flanger for the automobile pre-silencer is simple in overall structure and convenient to realize. When the barrel flanger for the automobile pre-silencer works, a silencing barrel of the pre-silencer is supported by the left supporting seat (6) and the right supporting seat (7), the left flanging mould (4) and the right flanging mould (5) can be aligned with the silencing barrel accurately, and therefore the effect that an end opening of the silencing barrel is smooth after the silencing barrel is flanged can be guaranteed.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a cylinder flanging machine for the front muffler of an automobile. Background technique [0002] With the rapid development of the economy, people's living standards are constantly improving, and the use of cars is also increasing. While automobiles are convenient for people's daily life, the noise generated during the exhaust process has also become the main source of noise in today's noise pollution. In order to reduce the noise pollution produced by automobiles, mufflers are all provided on today's automobiles, so the production of mufflers has increased dramatically. [0003] In the production process of the front muffler of the automobile, the end cover needs to be connected to the muffler cylinder of the front muffler by snapping, which involves flanging the muffler cylinder. The existing flanging machine is often operated by Manually align the muffler with the flanging mold, and m...
