Description

But quick adjustment plastic mechanism of door frame door column board hilt

Technical Field

The utility model relates to a but mould, especially a but quick adjustment plastic mechanism of door frame door post board sword handle in the automobile parts production research field.

Background

The door frame comprises top strip, reinforcing plate, 2 gatepost boards. Wherein, the door post plate is obtained by the processes of edge covering and spot welding of the inner plate and the outer plate. The production process of the outer plate comprises the following steps: OP05 rolling and bending to produce a door post outer plate rolling semi-finished product; OP10 rolling the upper end of the semi-finished product to hang a notch; OP20 rolling the upper end of the semi-finished product to hang a notch; forming the semi-finished product of OP30 into leaves; cutting edges of the leaf surfaces of the semi-finished OP40 product; and turning 90-degree edges of the semi-finished product of OP50 leaves and shaping the leaves by a knife handle.

For the OP40 leaf surface trimming, a long section of 'knife handle' is formed after the lower end of the semi-finished product is trimmed, the produced rolling piece has high strength, and after the lower end leaf surface is integrally cut off, the stress balance of the lower end is damaged, and the stress is released, so that the knife handle swings outwards.

After the cutter handle swings outwards, the cutter handle must be shaped, OP50 has a cutter handle shaping station, but the swinging amount of the cutter handle is directly influenced by a rolling piece, the rolling piece is directly influenced by a force material YP value, and the material YP value is an interval value, so the swinging amount of the cutter handle is basically consistent with that of a semi-finished product rolled in the same batch, different batches have changes, sometimes the change amount exceeds quality control, a mold needs to be debugged, and the size is adjusted to be in a qualified range. The shaping of the tool holder is realized by adopting a traditional side shaping mechanism, the shaping block is arranged on the wedge and driven by the wedge to work, and the lower module is arranged on the lower die base and is fixed. The shaping block is arranged in the die cavity, screws and pins are inconvenient to disassemble and assemble, particularly the pins take time, if the knife handle is very long and the shaping block is heavy, the die can be disassembled from the punch and then debugged, and if the experience is insufficient, the action can be repeated for many times, so that the time is more taken, and the production is influenced. And because the shaping piece is in the die cavity, maintenance personal must get into the operation in the mould with both hands, and the safety risk is very high.
