Abstract
The utility model relates to a mechanical processing die, in particular to a blanking punching die. The blanking punching die is provided with an upper die and a lower die. The upper die and the lower die are respectively arranged in upper and lower configuration. The upper die and the lower die are made of nodular cast iron. A protruding die is arranged on the bottom of the upper die through a bolt. A W-shaped groove is formed in the bottom of the protruding die. Annular tubes are arranged around the bottom of the protruding die. A concave die is arranged on the upper portion of the lower die through a bolt. A W-shaped groove is formed in the top of the concave die. Annular tubes are arranged around the top of the concave die. Bottoms of four guide rods are inserted into the annular tubes of the concave die. The guide rods are provided with spring pockets which are arranged in the annular tubes of the concave die and stretch out of the top of the concave die to a certain height. The four guide rods are provided with cushion blocks which are provided with circular through holes formed in the middle of the cushion blocks, and the cushion blocks are arranged above the concave die. The blanking punching die has the advantages of being reasonable in structure design, effectively prolonging service life of the blanking punching die due to a role of the spring pockets, and reducing processing noise. Due to the fact that the cushion blocks limit positions, working parts don't move when punched, and therefore machining accuracy is improved.
Description
Technical field
The utility model relates to a kind of machining mould, specifically relates to a kind of blanking punch die.
Background technology
The forging forming of W shape workpiece is by the moulding of blanking punch die punch process.
Summary of the invention
For the technical problem that exists in the prior art, the utility model provides a kind of blanking punch die of structural design novelty.
To achieve these goals, the technical scheme of employing is as follows:
The blanking punch die is characterized in that, has to go to upper and lower the upper die and lower die of arranging, and the material of upper die and lower die is spheroidal graphite cast-iron,
The patrix bottom is equipped with punch by bolt, and the punch bottom is provided with the W connected in star, and punch is provided with sleeve pipe around the bottom;
Counterdie top is equipped with die by bolt, and the die top is provided with the W connected in star, is provided with sleeve pipe around the die top;
Four guide rods, insert in the sleeve pipe of die the bottom, and guide rod is provided with spring housing, and spring housing places the sleeve pipe of die, and stretches out die top one height;
Four guide rods are provided with the cushion block that the middle part has manhole, and cushion block places the top of die.
The utility model blanking punch die, reasonable in design, under the spring housing effect, but the Effective Raise die life, and reduce the processing noise.Spacing lower at cushion block, workpiece can not be moved when punching press, thus the Effective Raise machining accuracy.
