Description
Technical Field
The utility model belongs to the forging field, concretely relates to interior hexagonal bolt forging mould.
Background
As is well known, bolt forgings on airplanes belong to important parts and are fasteners, and play an important role in the whole service process of airplanes. However, one bolt belongs to an internal hexagonal bolt, and the bolt is formed by backward extrusion of a punch during forging, so that the punch is seriously worn in the forging process due to various unfavorable reasons of materials, the punch needs to be frequently replaced, inconvenience is brought to production, and cost is increased.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is that: the die for the inner hexagonal bolt forge piece is provided, when the inner hexagonal bolt is forged, the abrasion part of the punch can be changed rapidly, the precision of the forge piece is guaranteed, and meanwhile, the production cost of the forge piece is saved.
The technical scheme is as follows:
an internal hexagonal bolt forging die, comprising: punch 1, bed die 2, hexagonal insert 3, wherein, the die cavity of bed die 2 includes bolt pole portion chamber, bolt head chamber and drift guide way in proper order, and the head of punch 1 is provided with the recess, and the hexagonal insert 3 includes fixed part and hexagonal extrusion portion, and the fixed part that the hexagonal was inserted 3 is fixed in the recess, and the hexagonal extrusion portion that the hexagonal was inserted 3 is used for extruding the bolt head and forms interior hexagonal structure.
Further, the side wall of the groove of the punch 1 is provided with a mounting through hole, and the wedge 4 is placed in the mounting through hole to fix the fixing part of the hexagonal insert 3 with the groove.
Further, the shank of the punch 1 is provided with a through hole communicating with the recess for separating the hexagonal insert 3 from the punch 1.
Further, the outside of the stem portion of the punch 1 is provided with a first recess.
Further, the inside wall of drift guide way is provided with the collecting vat for collect the cinder that forges the production.
Further, the lower part of the female die 2 is provided with a second concave part which is communicated with the rod part cavity of the bolt so as to facilitate clamping of the bolt.
The utility model has the advantages that: the overall die repairing time is reduced, the production efficiency is improved, and the production cost of the inner hexagonal bolt forge piece is reduced.

Detailed Description
The utility model provides a new modified device, it changes rapidly after the drift wearing and tearing forging backward extrusion in-process, makes it reach the accurate requirement of forging, has practiced thrift forging manufacturing cost simultaneously.
As shown in fig. 1-3, an internal hexagonal bolt forging die comprises: punch 1, bed die 2, hexagonal insert 3, wherein, the die cavity of bed die 2 includes bolt pole portion chamber, bolt head chamber and drift guide way in proper order, and the head of punch 1 is provided with the recess, and the hexagonal insert 3 includes fixed part and hexagonal extrusion portion, and the fixed part that the hexagonal was inserted 3 is fixed in the recess, and the hexagonal extrusion portion that the hexagonal was inserted 3 is used for extruding the bolt head and forms interior hexagonal structure.
Further, the side wall of the groove of the punch 1 is provided with an installation through hole, and the wedge 4 is placed in the installation through hole to fix the fixing part of the hexagonal insert 3 with the groove.
Further, the shank of the punch 1 is provided with a through hole communicating with the recess for separating the hexagonal insert 3 from the punch 1.
Further, a first recess is provided outside the stem portion of the punch 1.
Further, the inside wall of drift guide way is provided with the collecting vat for collect the cinder that forges the production.
Further, the lower part of the female die 2 is provided with a second concave part which is communicated with the rod part cavity of the bolt so as to facilitate clamping of the bolt.
The present invention will be further described with reference to the following examples.
Example 1: inner hexagonal bolt forging material: 40CrNiMoA, and the blanking specification is as follows:
quantity: 400 pieces.
The die forging adopts 1-fire two-step turning forging, the die forging equipment adopts a 6300KN horizontal forging machine, and 200 pieces of inner hexagonal bolt forge pieces are produced, and then the lower hexagonal head insert blocks are detached.
Step one, placing a hexagonal head insert in a corresponding position of a punch.
And step two, placing the wedge in a corresponding position of the punch.
And step three, tightening the wedge by using a ram to enable the square head insert, the wedge and the punch to be tightly matched together.
The size of the 400 inner hexagonal bolt forgings produced by the scheme completely meets the requirements of drawings.
