Abstract

The invention relates to the technical field of automobile spare parts and discloses a filament bending device for an automobile. The bending device comprises a first cylinder body. A first limiting groove is arranged in the inner surface of the first cylinder body. The first cylinder body is in sliding connection with a second cylinder body. A second limiting groove is arranged in the outer surface of the second cylinder body. The second limiting groove and the first limiting groove are oppositely arranged. Up-down symmetrical clamping plates are arranged in the second cylinder body. The clamping plates are arranged to be close to the inner wall of the second cylinder body. Space where filaments are arranged is formed between the clamping plates. Elastic pieces are connected between the clamping plates and the inner wall of the second cylinder body. Through holes are arranged in the second cylinder body and are in sliding connection with pushing rods. The pushing rods are abutted against the clamping plates. By inserting the filament into the second cylinder body, under the squeezing function of the first cylinder body, the filament is fixed and bent. The bending device is advantaged by good filament bending effects and high bending precision.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a bending device. Background technique [0002] The production of light bulbs for automotive lighting includes multiple processes. Generally, the filament is wound first to form a spiral body, and then the straight edge at one end of the spiral is bent 90 degrees to be parallel to the straight edge at the other end. The side is welded on the molybdenum rod, and then the molybdenum sheet is welded on the molybdenum rod, then packaged with a glass bulb, and finally installed on the lamp holder. [0003] Generally speaking, wire winding, cutting and bending are continuously completed on the wire winding machine. For the process of bending straight edges, it is realized by installing bending components on the wire winding machine. When the existing bending assembly bends the filament, it is easy to break the filament, resulting in defective products, and when the filament is bent...
