Abstract
Description
Technical Field
[0001] This application relates to the field of test tube brush processing technology, specifically to a fully automatic straightening mechanism and straightening method for test tube brushes. Background Technology
[0002] Test tube brushes, also known as tube brushes, straw brushes, or hole cleaning brushes, are brush products composed of a steel wire skeleton and outward-extending fine bristles. The bristle materials include nylon filaments, fiber bristles, pig bristles, steel wire, copper wire, abrasive filaments, etc. They can be widely used for deburring and polishing operations inside holes in hydraulic valve holes, machining, medical pipelines, and air conditioning and refrigerator compressors.
[0003] During the processing of test tube brushes, the bristle material is usually placed directly on the outside of two steel wire frames, and then the two steel wires are twisted to fix the bristle material. During assembly, because the product is assembled using a press mold, the concentricity of the product cannot be guaranteed. This results in excessive product vibration during use due to excessive concentricity, leading to instability in the use of the test tube brush. Therefore, to address the above problems, a fully automatic straightening mechanism and straightening method for test tube brushes are proposed. Summary of the Invention
