The invention relates to the field of car bulb supports, in particular to a lamp filament bending assembly for a car. The lamp filament bending assembly comprises a fixed cylinder, a bending device and a hydraulic rod; and the fixed cylinder is sleeved with the bending device, the bending device comprises a sleeve, a columnar rod and a clamping mechanism, an opening of the sleeve and an opening ofthe fixed cylinder are oppositely arranged, the end, away from the fixed cylinder, of the sleeve is connected with the hydraulic rod, the columnar rod is fixedly connected to the central axis of thesleeve, the clamping mechanism comprises multiple elastic parts and two annular plates, the inner side faces of the annular plates are connected with the side face of the columnar rod through the elastic parts, the end, close to the front of the sleeve, of the annular plate is provided with an inclined part which inclines downwards, and the length of the annular plate and the columnar rod is larger than that of the sleeve. Through pushing of the hydraulic rod, bending and fixing of a filament can be achieved, and the problem that in the prior art, two straight filaments of the lamp filament can relatively incline in the bending process, and thus the two straight filaments are not parallel is solved.
Description
technical field [0001] The invention relates to the field of automobile bulb holders, in particular to the field of bending automobile filaments. Background technique [0002] The production of automotive lighting bulbs (such as 24VH1 bulbs) includes multiple processes. Generally, the filament is wound first to form a spiral, and then the straight wire at one end of the spiral is bent 90 degrees to be parallel to the straight wire at the other end. Then two straight wires are 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. For the process of bending straight wires, it is realized by installing bending components on the wire winding machine. The existing bending assembly generally includes a support frame and an extrusion block. The support frame is composed of a horizontal base and a support column vertically fixed to the horizontal base. A right-angled di...
