Description
Technical field
The application relates to a kind of metal plate punching forming technique in aircraft manufacturing field, specifically a kind of plate threeway semicanal punch die, be particularly suited for complex-shaped, irregular structure plate threeway semicanal is stamping.
Background technology
Manufacturing field at airplane parts, predominantly middle part is wrinkling for plate threeway semicanal forming defects, put limit ruptures.Applicant at first patent " composite punching die of a kind of threeway half tube components ", application number 201420061972.7, disclose a kind of punching die structure that can reversely compress plate, although overcoming wrinkling problem in the middle part of plate threeway semicanal, but still there is following defect: this diel makes push rod position co-ordination at itself and platen three by tangentially extending along the mouth of pipe, mould is directly placed into workbench when installing by mould, is only applicable to that shape is the most regular and similar T shape threeway semicanal is stamping.Owing to lathe mandril position is set to the distribution of equidistant rectangular-shaped rule, there is problems of ensureing two points and push rod location matches for complicated shape threeway semicanal diel, during punching press, compact heap is by force unbalance, be there is bigger limitation so limiting by threeway half tube shape in terms of popularization and application.
Summary of the invention
Solving to overcome prior art to be difficult to be difficult to and lathe push rod position phase coordination problem when complex-shaped threeway semicanal diel is installed, the purpose of the application is to provide one to be applicable to complex-shaped, irregular structure threeway semicanal diel.This diel operation principle is, by keyset below lower mold, buffer brake is delivered to lower mold built-in core mould, can realize arbitrary shape threeway semicanal diel and all can complete punching press on lathe.
nullA kind of threeway semicanal punching die structure，Comprise lower mold、Core、Upper mold、Keyset，It is characterized in that: the body of described lower mold is a slab construction，The outer die body mated with threeway semicanal of protrusion is had at the middle part of flat board，There is the part outer mold surface of the form fit with threeway semicanal the inner side of outer die body，The interior side-lower of outer die body is a threeway shape groove，Three vertical guide through hole are distributed on the lower mould body of threeway shape trench bottom，Described core is embedded in the inner side of outer die body，The body of core is a threeway shape compact heap mated with above-mentioned threeway shape groove，The upper surface of this compact heap is connected with the part outer mold surface of side in the external mold body of upper mold，Constitute the complete external form concave surface mated with threeway semicanal，The lower surface of this core body is perpendicular to the threeway direction of compact heap and is provided with three corresponding with above-mentioned guide through hole bearing column；The body of described upper mold is also a slab construction, and the lower surface in upper mold is provided with the external form convex surface mated with threeway semicanal, and this external form convex surface can embed in above-mentioned external form concave surface；Described keyset is a slab construction equally, and this keyset is in below lower mold, and the lower surface of keyset and lathe ejector pin contact, the bearing column of core is crimped on the upper surface of keyset.Active force is delivered to core compact heap by keyset and bearing column by lathe push rod, makes plate be in lasting impaction state and completes to shape.
The using method of above-mentioned plate threeway semicanal diel, is first positioned over described keyset above lathe push rod, then lower mold is supported on by cushion block the top of keyset；After the bearing column of core is crimped on through the guide through hole of lower mold the upper surface of keyset, sheet material to be formed is placed between upper mold and lower mold, buffer brake is delivered to core by keyset and bearing column by lathe push rod, make sheet material jointly be acted on by core and upper mold external form convex surface and be in lasting impaction state, then make upper mold and core Tong Bu move downward gradually matched moulds and complete the stamping of threeway semicanal.
The application provides the benefit that:
1. buffer brake is acted on built-in core mould by keyset by the application, it is achieved the three-way valve mold of arbitrary shape all may be mounted to lathe punching press, is not limited by three-way shape, applied widely.
2. the application is used middle part reversely compaction techniques, and punching course produces frictional force and can alleviate woollen and press inclined problem, advantageously reduces the required woollen of shaping, simultaneously in the middle part of wrinkling district excess stock be excluded and add to weakened section, greatly alleviate weakened section cracking.
3. the bearing column of the used built-in core mould of the application is both as intermal force, also serves as the guide effect of core and lower mold simultaneously, is not required to separately arrange guiding and can realize the smooth matched moulds of punching course, prevents crossing location between mold component and causes abrasion.
