Abstract

The utility model relates to a sensor gear ring drawing die, in particular to a die for manufacturing A2 sensor gear ring drawing. The sensor gear ring drawing die discloses that a holding pad upper end part which is fixed on a push rod is arranged around a convex die, a chamfer angle of 10 degrees to 85 degrees, which is pressed on a workpiece flange zone, is arranged on the holding pad, concave dies are fixed around a hitting plate, and the concave dies are matched with the outer shape of the holding pad. The structure can be adopted when a plurality of special shaped holes with different seizes, shapes and positions in various drawing diameter ranges in the gear ring products are demanded for manufacturing, the breaking or neck reducing phenomena can not be generated due to drawing, the quality is stable, the demanded range of annealing states can be widened, and the product pass percent can achieve demands.

Description

A kind of sensor gear ring drawing die

Technical field

The utility model relates to a kind of mould of making auto parts, specifically a kind of making A ₂The drawing die of sensor gear ring.

Background technology

A ₂The sensor gear ring, as Fig. 4, shown in Figure 5, the flange of gear ring and stretching cross section pull into 90 °, the common product smooth atresia in the material ranges that is stretched, can directly pull into 90 ° of shapes to drawing, but work as the product parts that the material ranges that is stretched has not of uniform size and porous, cause easily at drawing process and break between the hole or necking down, quality is very unstable, and product percent of pass is low.

Summary of the invention

The utility model provides a kind of sensor gear ring drawing die, and it has overcome the defective of present technology after to conventional mould transformation, when the gear ring product has various irregularly-shaped hole, can not occur disconnecting or necking constant product quality.

Technical solution of the present utility model is that it comprises cope match-plate pattern at existing mould, lower bolster, upper padding plate, die shank is made bar, re-pack punch, alignment pin, push rod, guide pillar is on the basis of guide pin bushing, the utility model is that the punch periphery has holding pad to be fixed on the upper end of push rod, compacting workpiece ledge zone has 10 °-85 ° chamfering on the described holding pad, and the periphery that re-packs is fixed with die, and die is suitable mutually with the holding pad profile.

More than the chamfering of 20 °-50 ° of compacting workpiece ledge zone is arranged on the holding pad described in the utility model, the compacting workpiece ledge zone and the holding pad of die correspondence adapt.

The chamfering that 30 °-40 ° of compacting workpiece ledge zone are arranged on the holding pad described in the utility model.

Advantage of the present utility model is a plurality of sizes are arranged when the gear ring product stretches in each diameter range, and shape during the irregularly-shaped hole that differs in the position, adopts this structure to draw, and can not occur disconnecting or necking steady quality, qualification rate height.
