Device for automatically correcting circular degree

Abstract

The invention provides a device for automatically correcting the circular degree. The device comprises a fixing plate (3) and a cavity die plate (7); the fixing plate (3) is provided with a vertical correction core die (12); the cavity die plate (7) is provided with a core shaft fixing seat (21) which is provided with a rotatable core shaft (18); the core shaft (18) is located under the vertical correction core die (12); rotating positioning mechanisms are arranged on the fixing plate (3) and the cavity die plate (7) and behind the core shaft (18). According to the device for automatically correcting the circular degree, gears and racks which are arranged in the rotating positioning mechanisms are matched with each other to stably control a directional shaft to drive the core shaft to rotate and accordingly the circular degree of a circle tubular component is accurate and accordingly the production process is effectively simplified and the production rate 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
