Description

Side hole flanging die of upper cross plate of automobile seat backrest

Technical Field

The utility model relates to the technical field of mold, especially, relate to a car seat back upper cross plate side hole flanging mould.

Background

The top of the automobile seat backrest is provided with a headrest, a headrest rod is arranged on the headrest, a headrest guide pipe is arranged at the top of the automobile seat backrest, and the headrest rod is connected with the top of the automobile seat backrest after being inserted into the headrest guide pipe. Be provided with two pipe spliced eyes on automobile seat back upper transverse plate, peg graft in two pipe spliced eyes that correspond with same headrest pipe, stamping forming is an important mode that forms the pipe spliced eye, insert the pipe spliced eye smoothly in order to guarantee the headrest pipe, two pipe spliced eyes that correspond should have good concentricity, and to hole flanging with one side, current automobile seat back upper transverse plate hole flanging die adopts a drift to punch press two just right turn-ups of last diaphragm in proper order, form concentric hole flanging, the stroke of this kind of hole flanging stamping die is longer, stability is not good, the quality of product is not high after the punching press. The utility model discloses a utility model for CN204122572U provides car seat back entablature side hole flanging mould, this mould punches a press through two drifts, has reduced the stroke of single drift, has improved punching press stability, and the concentricity of hole flanging is high, and the punching press stable quality, the qualification rate of product is high, and drift return means sets up ingeniously, compact structure.

However, two punches of the die need to be driven by two independent power sources, so that the punching operation is realized, and a gap is formed between the transverse plate on the seat back and the outer wall of the male die, so that the outer side wall of the male die can not well support the flanging at two sides of the transverse plate on the seat back, and the flanging of the transverse plate on the seat back is easy to deform in the punching process. Secondly, this mould adopts the nitrogen gas extension spring to reset to the drift, and consequently this mould need connect the gas source to use, leads to use cost to uprise, so the utility model discloses make the improvement to car seat back entablature side hole flanging die.
