Abstract
The utility model relates to an extrusion die for an external protection ring, which belongs to the extrusion die for an external protection ring for a front overhang soft pad of an engine. The utility model provides the extrusion die for an external protection ring with high productive efficiency. The utility model comprises a lower die plate, and is characterized in that a conical die core is arranged on the lower die plate, and the upper die plate is arranged above the conical die core. Because the utility model is the extrusion die, a sand hole does not exist in an extruded workpiece. The utility model has the advantages of high strength, once targeting of the dimensional accuracy, relief of other mechanical processes and high productive efficiency.
Description
Technical field:
The utility model belongs to the extrusion die of the outer guard ring of engine front overhang cushion.
Background technology:
Outer guard ring is generally steel-casting at present, but sand holes are easily arranged, and insufficient strength; In addition, because of size has error, must be through machining, therefore, production efficiency is low.
The utility model content:
The utility model is exactly at the problems referred to above, and the extrusion die of the high outer guard ring of a kind of production efficiency is provided.
The utility model adopts following technical scheme: the utility model comprises lower bolster, and it is provided with the taper core rod above structural feature lower bolster, and taper core rod top is a cope match-plate pattern.
The beneficial effects of the utility model:
Because the utility model is an extrusion die, the workpiece that extruding is come out does not have sand holes, and the intensity height, but other machining has been removed in the dimensional accuracy one-time-reach-place from.Therefore, production efficiency height.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model structure of the bottom of the cope match-plate pattern projection that has arc for the side.
The specific embodiment:
The utility model comprises lower bolster 1, is provided with taper core rod 2 above the lower bolster 1, and taper core rod 2 tops are cope match-plate pattern 4.
The bottom of cope match-plate pattern 4 can be and taper core rod 2 corresponding Baltimore grooves 5.
The bottom of cope match-plate pattern 4 can be the projection 8 that the side has arc 6.
Like this, the utility model just can be pressed into conical workpieces 3 with part on the hollow cylinder; Can be pressed into the top again and have the conical workpieces 3 of flanging 7.
