Description

The spliced mould of a kind of insert

Technical field

The utility model relates to mechanical forging field, particularly relates to the spliced mould of a kind of insert.

Background technology

Stamping machine, as a kind of forging equipment, is widely used in the middle of mold casting process of being everlasting, and relies on stamping machine and mould to apply external force to tabular billot, makes billot produce plastic deformation or separation, thus obtain the stamping parts of required form and size.Punching press comprises distortion operation and separation circuit two kinds, and separation circuit also claims stamping-out, its objective is and stamping parts is separated from billot along certain outline line, ensures the quality requirement being separated section simultaneously.The object of forming process makes billot, under the condition of not broken base, plastic deformation occur, make the blank of required form and size, but the use procedure of stamping machine has very large danger, stamping machine is in the process of carrying out mould punching, in order to mould punching is shaping, strength when drift and contacting dies is very huge, so there is very high requirement to the intensity of mould, but there is significant limitation in the mould of entirety, when carrying out punching press, stress can be concentrated, thus cause crack of die, as shown in a, mould 6 ＇ fault is the easiest produced problem in punching production, usually cause stopping production, affect life cycle of the product, on the other hand, the die cost of punching production is high.Usual mould expense accounts for the 1/5-1/4 of product totle drilling cost.This is because Making mold difficulty is large, cost is high, mould after putting into production repair and sharpening maintenance cost also high, and the original cost of mould only accounts for about 40% of whole die cost.Therefore, prevent burn failure, greatly can reduce the die cost of punching production.

Utility model content

The purpose of this utility model is for the deficiencies in the prior art part, overcomes the problem because mould local stress causes mould premature wear to break, provides a kind of insert spliced mould, and changing unitary mould is the spliced mould of insert.

Technology correspondence of the present utility model adjustment is as follows:

The spliced mould of a kind of insert, comprise outer ring die, interior ring mould and connecting key, interior ring mould is placed in outer ring die, is connected by connecting key;

Outer ring die entirety is in annular, and inside has the first groove, the second groove, and the first groove, the second groove symmetry are offered;

Inner ring mold integral is rounded, and edge part has the first breach, the second breach, and described first breach, the second breach symmetry are offered, and interior ring mould is provided with two symmetrical guide rod holes, for push rod;

Connecting key entirety is triangular in shape, and inner first groove of outer ring die is corresponding with interior ring mould first breach, inner second groove of outer ring die is corresponding with interior ring mould second breach, both is connected by connecting key.

As improvement, outer ring die external diameter is D, and outer ring die internal diameter is d, and interior ring mould external diameter is d; The value of D/d is in 1.6 ~ 2.5 scopes.

As improvement, the value of D/d is 1.8.

As improvement, the fit system of outer ring die and interior ring mould is interference fit.

As another improvement, connecting key is divided into Part I, Part II, and Part I is positioned at the first groove and the second groove, and Part II is positioned at the first breach and the second breach.

As another improvement, connecting key edge has chamfering.

As further improving, the Part I of connecting key is equal on vertical height with Part II.

As further improving, the spliced mould of insert is made up of high-speed steel.

The beneficial effect of the present embodiment: the utility model provides the spliced mould of a kind of insert, overcome the problem because mould local stress causes mould premature wear to break, changing unitary mould is the spliced mould of insert, unitary mould stress is concentrated, die life can be shortened, the precision of processing work is caused to reduce, block insert type mould fully solves mould local stress problem, stress is graded process, born together with interior ring mould by outer ring die respectively, after stress dispersion, mould strength improves, improve die life, improve working efficiency.
