CN102873171A - Blanking die - Google Patents

Abstract

The invention relates to a machining die, and in particular relates to a blanking die. The blanking die is provided with an upper die, a lower die and four guide rods; upper and lower dies are arranged vertically and are made of nodular cast iron; the bottom of the upper die is provided with a male die through a bolt; a W-shaped groove is arranged at the bottom of the male die; a casing is arranged around the bottom of the male die; the upper part of the lower die is provided with a female die through the bolt; the W-shaped groove is arranged at the top of the female die; the casing is arranged around the top of the female die; bottoms of the four guide rods are inserted into the casing of the female die; spring sleeves are arranged on the guide rods, and are sleeved in the casing of the female die and stretch out of the top of the female die in height; cushion blocks with round through holes in the middle are arranged on the four guide rods, and are arranged above the female die. The blanking die disclosed by the invention is reasonable in structural design; under actions of the spring sleeves, service life of the die can be effectively improved, and machining noises can be reduced; a workpiece cannot move during punching under being limited by the cushion blocks, so that machining precision is effectively improved.

Description

The blanking punch die

Technical field

The present invention relates to a kind of machining mould, specifically relate 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 invention 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.

Blanking punch die of the present invention, 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.

Description of drawings

For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present invention.

The specific embodiment

See also Fig. 1, the blanking punch die has and goes to upper and lower patrix 1 and the counterdie 10 of arranging, and the material of patrix 1 and counterdie 10 is spheroidal graphite cast-iron.

Patrix 1 bottom is equipped with punch 3 by bolt 2, and punch 3 bottoms are provided with W connected in star 5, is provided with sleeve pipe 4 around punch 3 bottoms.

Counterdie 10 tops are equipped with die 12 by bolt 13, and die 12 tops are provided with W connected in star 11, are provided with sleeve pipe 9 around die 12 tops.

Four guide rods 6, insert in the sleeve pipe 9 of die 12 bottom, and guide rod 6 is provided with spring housing 8, and spring housing 8 places the sleeve pipe 9 of die 12, and stretches out die 12 tops one height.

Four guide rods 6 are provided with the cushion block 7 that the middle part has manhole, and cushion block 7 places the top of die 12.

Above content only is to structure example of the present invention and explanation; under those skilled in the art described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
