A roundness automatic correction device

Abstract

The invention provides an automatic roundness correction device, comprising a fixed plate (3) and a concave template (7), the vertical correction punch (12) is installed on the fixed plate (3), and the concave template (7) ) is installed with a mandrel fixing seat (21), and a rotatable mandrel (18) is installed on the mandrel fixing seat (21), and the mandrel (18) is located directly below the vertical correction punch (12), and the A rotary positioning mechanism is installed on the fixed plate (3) and the concave template (7) and behind the mandrel (18). This device uses the cooperation of the gear and the rack in the rotary positioning mechanism to stably control the rotation of the mandrel driven by the orientation shaft. , so that the roundness of the round tubular parts is accurate, the production process is effectively simplified, and the productivity is improved.

Description

technical field [0001] The invention relates to an automatic roundness correction device for round tubular parts. Background technique [0002] Round tubular parts are widely used in people's daily life. Round tubular parts are usually bent into wave shapes from flat blank profiles, and then the wave shaped profiles are bent into round tubes. The roundness of the bent round tubes is poor, and the roundness requirements are higher For high-precision products, roundness correction must be performed in all directions around the round tube part. [0003] In the prior art, the roundness correction of the round tube part is usually to put the round tube part on a rotating mandrel of the stamping die, fix it on the mandrel and cooperate with the dial block and be driven by the dial block fixing rod and the dial block. The roundness correction is carried out by the method of intermittently rotating the rotating parts. This method can correct the roundness more accurately, but becau...

[0003] In the prior art, the roundness correction of the round tube part is usually to put the round tube part on a rotating mandrel of the stamping die, fix it on the mandrel and cooperate with the dial block and be driven by the dial block fixing rod and the dial block. The roundness correction is carried out by the method of intermittently rotating the rotating parts. This method can correct the roundness more accurately, but because this method is a single-action form, the mold needs to work six times continuously to complete the roundness correction of a part. Production The efficiency is low and the effect of the shifting block on the rotating part makes it difficult to control the stop of the rotating part, thus causing problems such as unstable roundness correction quality
