Description

Improved structure of motor cover drawing die

Technical Field

The utility model belongs to the mould field, in particular to production machining efficiency is high, effectual motor cover drawing die improves structure.

Background

The motor cover (as shown in figure 2) is formed by processing a stretching die, the stretching die of the motor cover used at present is characterized in that a lower die of the stretching die is powered by an oil press, and the lower die is guided by a common guide rod.

The to-be-solved technical problem of the utility model is to provide a motor cover drawing die improves structure that driving speed is fast, machining efficiency is high, the direction atress is even difficult for card mould, the fault rate is low need not frequent maintenance, does not influence normal production, effectively satisfies production and processing demand.

SUMMERY OF THE UTILITY MODEL

For solving above-mentioned prior art hydraulic press drive speed very slow, to production machining efficiency influence big, mould machining efficiency is low, the guide arm direction atress is inhomogeneous easily block mould, mould fault rate is high, need frequent maintenance, influence normal production, can't satisfy production machining demand scheduling problem, the utility model discloses a following technical scheme:

the utility model provides an improved structure of a motor cover drawing die, which comprises an upper die base, a female die forming cavity, a blank holder, a pair of lower support plates, a lower die base, a forming punch, a pair of lower die guide pins, a plurality of nitrogen springs, a lower pad pin and a lower support plate, the female die forming cavity is fastened at the center of the bottom of the upper die base through a bolt, the blank holder is fastened at the bottom of the female die forming cavity, the lower die base is arranged right below the upper die base, the pair of lower retainer plates are symmetrically arranged at two ends of the lower die base, the forming punch is arranged in the middle of the lower die holder, the forming punch is positioned under the female die forming cavity and is completely matched with the female die forming cavity and the blank holder structure, the pair of lower die guide pins are symmetrically inserted at two ends of the lower die base, the lower supporting plate is arranged below the lower die base through the lower pad pins, the nitrogen springs are sequentially arranged on the lower supporting plate, and the tops of the nitrogen springs are connected with the lower die base.

As a modification of the utility model, the upper die base and the lower die base are both provided with die cavities.

The beneficial effects of the utility model reside in that: the nitrogen spring drives the lower die to move and guide through the guide pins, so that the driving speed is high, the machining efficiency is high, the guide stress is uniform, the die is not easy to clamp, the failure rate is low, frequent maintenance is not needed, normal production is not influenced, and the production and machining requirements are effectively met.
