Abstract

The utility model discloses a no die structure of punching a hole, it includes left side dog and right side dog, form the station that punches a hole between left side dog and the right side dog, the front end of station of should punching a hole is equipped with one and leans on the piece, it is equipped with a drift to punch a hole the top of station, the terminal surface of this drift forms an obliquely drift tangent plane, the drift tangent plane is recessed cambered surface form, punch a hole and be equipped with one on the station and dash in advance, the surface that should dash the piece in advance is equipped with one and punches a hole in advance, it upwards forms the pre -compaction line that the round sealed the form along the outer fringe of punching a hole in advance to dash a lower surface in advance. Its beneficial effect lies in: 1, do not have the die, the blanking relies on drift and product body to support completely and cuts the completion, 2, the drift need adopt the high -speed steel, and thermal treatment hardness is higher than more than the HRC62, 3, the face is punching sheared to the drift need make 30 oblique swoves, and selects product hole periphery to have the one side that props than the strong component to be originated cutter position, 4, the product is peripheral must to forbid the product and in die -cut horizontal removal occasionally, prevent the drift rupture with leaning on the piece jam -packed.

Description

A kind of no-female die piercing structure

Technical field

The utility model relates to the technical field of Mould Machining, specifically a kind of no-female die piercing structure, particularly its mechanical connecting structure.

Background technology

Traditional die-cut production is all realized by the shearing of drift and die, but in the product-forming that some is more special, die cannot be placed, and the mode that single operation can only be adopted product to be turned punching press has been come.Cannot realize the automated production of progressive die, its bottleneck is just that the position of holes of products is special, and die cannot be placed, and single operation production and waste of manpower cost, take board equipment, cannot ensure again requirement on machining accuracy, scrappage is high.

Summary of the invention

The purpose of this utility model is to provide a kind of no-female die piercing structure, by the improvement of punching apparatus, realizes specific position punching, also can realize automated production when die cannot be placed.

To achieve these goals, the technical solution of the utility model is: a kind of no-female die piercing structure, it is characterized in that: it comprises left side block and right side block, punching station is formed between left side block and right side block, the front end of this punching station is provided with one by block, the top of punching station is provided with a drift, the end face of this drift forms an oblique drift tangent plane, drift tangent plane is recessed arc surfaced, punching station is provided with a pre-stamping, the surface of this pre-stamping is provided with a pre-punched hole, pre-stamping lower surface upwards forms the pre-line ball of a circle closed along pre-punched hole outer rim.

The utility model discloses a kind of no-female die piercing structure, compared with prior art its beneficial effect is: 1, do not have die, and stamping-out relies on drift and product ontology to support shearing completely and completes; 2, drift need adopt high-speed steel, and heat treatment hardness is higher than more than HRC62 °; 3,30 ° of oblique cuttves need be made in drift punching face, and select holes of products periphery to have the comparatively strong one side supported to be initial cutter location; 4, product periphery with by block jam-packed, must not allow product when die-cut, have horizontal movement, prevents drift from fractureing.

Detailed description of the invention

With reference to the accompanying drawings, the utility model is described further.

The utility model discloses a kind of no-female die piercing structure, it is different from prior art and is: it comprises left side block 1 and right side block 2, punching station 3 is formed between left side block 1 and right side block 2, the front end of this punching station 3 is provided with one by block 4, the top of punching station 3 is provided with a drift 5, the end face of this drift 5 forms the drift tangent plane 6 of oblique 30 degree, drift tangent plane 6 is in recessed arc surfaced, punching station 3 is provided with a pre-stamping 7, the surface of this pre-stamping 7 is provided with a pre-punched hole, pre-stamping 7 lower surface upwards forms the pre-line ball of a circle closed along pre-punched hole outer rim.

Its know-why is: utilize product ontology to do shear support, and be oblique 30 ° of cut roll by the oblique cutter of drift by downward transfer of shear forces, dispersion punching shear, reaches the function getting final product punching without die.

Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
