Description
Technical field
The present invention relates to the T ironworking technology in electroacoustic, more specifically, it relates to a kind of high line diameter ratio T iron head combination die.
Background technology
In traditional T ironworking technology, for the line diameter ratio high line diameter ratio T iron product more than 4:1, four molds are all used to enter
Row processing, its substantially technical process be take the lead, integer, flattening, molding four procedure, every procedure is required for special mould.
It is more to there is operation in this traditional technique, the deficiency that production cost is high, there is necessity of improvement.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned deficiency for prior art, it is provided that a kind of simple in construction, can complete tradition
The above high line diameter ratio T iron head combination die of two procedures.
The technical scheme is that such: a kind of high line diameter ratio T iron head combination die, including lower mold and upper mold, Qi Zhongsuo
The lower mold stated is to be made up of lower mold main body, lower mold core and push rod, and lower mold core is embedded in lower mold main body, and lower mold core and lower mold master
The upper surface of body is generally aligned in the same plane；Being provided with forming hole in the middle part of described lower mold core, described forming hole top is up big and down small
Cone, bottom is cylindrical, and the degree of depth of cylindrical part is 1.5～3mm；Described push rod is worn from lower mold bottom part body activity
Enter its upper surface to be positioned at below the forming hole of lower mold core；Described upper mold is to be made up of a punch die and two punch dies, wherein said one
Being provided with lower big little bellmouth in the middle part of punch die, the lower port diameter of bellmouth is slightly larger than the external diameter of material to be breasted the tape；Two described punchings
Mould is again to be made up of upper mould body and upper mold core, and described upper mold core is embedded in upper mould body, be provided with in the middle part of upper mold core lower greatly
Upper little conical indentations, during punch forming, bellmouth is all consistent with the axis of forming hole with the axis of conical indentations.
Further, in above-mentioned high line diameter ratio T iron head combination die, the cylindrical degree of depth of described forming hole bottom is 2mm.
In above-mentioned high line diameter ratio T iron head combination die, described upper mold core is generally aligned in the same plane with the lower surface of upper mould body.
The present invention compared with prior art, has an advantage that
Use the assembling die of the present invention, taking the lead in traditional handicraft, integer two procedures can be completed, make whole T ironworking
It is reduced to three process by four original procedures, greatly saves production cost and improve production efficiency.
Accompanying drawing explanation
Specific embodiment in connection with figures below, the present invention is described in further detail, but do not constitute and appoint the present invention
What limits.
Fig. 1 is one of structural representation of the present invention；
Fig. 2 is the two of the structural representation of the present invention；
Fig. 3 is one of working state schematic representation of the present invention；
Fig. 4 is the two of the working state schematic representation of the present invention.
In figure: lower mold 1, lower mold main body 11, lower mold core 12, forming hole 12a, push rod 13, punch die 2, bellmouth 2a,
Two punch dies 3, upper mould body 31, upper mold core 32, conical indentations 32a, workpiece 4.
Detailed description of the invention
Refering to shown in Fig. 1 and Fig. 2, the high line diameter ratio T iron head combination die of the present invention, including lower mold 1 and upper mold, the present invention
Specific embodiment described in lower mold 1 be to be made up of lower mold main body 11, lower mold core 12 and push rod 13, lower mold core 12 uses
Intensity and hardness higher alloy material processing, to ensure the mold use life-span；It is that lower mold core 12 is embedded in lower mold main body
In 11, and the upper surface of lower mold core 12 and lower mold main body 11 is generally aligned in the same plane；It is provided with molding in the middle part of described lower mold core 12
Hole 12a, described forming hole 12a top is up big and down small cone, and bottom is cylindrical, and the degree of depth of cylindrical part is
1.5～3mm, preferably 2mm, its objective is to be formed angle when one rushes；Described push rod 13 is lived bottom lower mold main body 11
Dynamic penetrate its upper surface and be positioned at below the forming hole 12a of lower mold core 12；Described upper mold is to be made up of a punch die 2 and two punch dies 3,
The lower port diameter of lower big little bellmouth 2a, bellmouth 2a it is provided with slightly larger than waiting to breast the tape in the middle part of a wherein said punch die 2
The external diameter of material；Two described punch dies 3 are again to be made up of upper mould body 31 and upper mold core 32, and described upper mold core 32 is embedded in
In mould main body 31, be provided with in the middle part of upper mold core 32 lower big little conical indentations 32a, bellmouth 2a and circle during punch forming
The axis of tapered recess 32a is all consistent with the axis of forming hole 12a；Upper mold core 32 described in the present embodiment and upper mold master
The lower surface of body 31 is generally aligned in the same plane.
When the present invention is specifically used, refering to shown in Fig. 3, Fig. 4, technique of taking the lead directly is cut at circle and be can be achieved with on heading machine,
What circle cut feeding of taking the lead is mechanical hand, and lower mold 1 is entered in finger feed when, when a punch die 2 dozens comes, mechanical hand is also
Do not unclamp, first the angle of workpiece 4 has been squeezed out by moment one punch die 2, just utilized angle to position.Charge bar material is allowed to be stuck in
In lower mold 1, after a punch die 2 is return, it is converted into two punch dies 3 and quickly beats, form the shape of an agaric head, be equivalent to
Take the lead and the trimming of traditional handicraft are done, and are greatly improved processing effect.
As a example by handicraft product PL0014062220S T iron product, the expendable weight of product is 79g, and post core diameter φ 13.95 cuts material
A length of 73 long, material ratio of height to diameter has exceeded 5:1, and directly the polish method of mushroom of technique cannot realize routinely, uses the present invention's
Mould, uses big wire rod 19.3mm, and the die treatment through the present invention becomes the shape of agaric head, lower bands diameter phi
The angle of 13.5mm, 2mm length, is ejected workpiece 4 by push rod 13 after completing, and can carry out the flattening process of bottom.
