One biggish die sleeve of set shares pulling force to increase the service life of wire drawing die.Wire drawing die is usually set in the die cavity of big die sleeve
It is interior, then wire drawing die is compressed by gland and passes through welding manner and fixes gland, for the ease of die sleeve is placed in mold
Butt welding contact is also wanted to machine processing on frame.Not only labor intensive is larger for insetting case technology traditional in this way, and there are also each drawings
Silk mould requires to be equipped with a big die sleeve, and big die sleeve usage quantity is more, expends resource, increases production cost.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of movable die sleeves convenient for wire drawing die clamping.
In order to achieve the object of the present invention, the invention adopts the following technical scheme:
A kind of movable die sleeve convenient for wire drawing die clamping, the activity die sleeve combined by the installation of the first die sleeve and the second die sleeve and
At first die sleeve is equipped with first step hole, and second die sleeve is equipped with coaxially arranged with the first step hole
Second step hole, the large aperture section in the first step hole are oppositely arranged with the large aperture section in second step hole and collectively form drawing
The Set and Positioning slot of silk mould, small-bore section and the small-bore in the second step hole section in the first step hole constitute and wire drawing die on
The wire drawing channel that wire drawing hole communicates.
Further technical solution: the internal diameter of the small-bore section of the small-bore section and second die sleeve of first die sleeve
It is gradually increased respectively to the direction far from the wire drawing die and forms cone angle.
Further technical solution: in platform-like, the first step hole setting exists for first die sleeve and the second die sleeve
On the table top of first die sleeve, the second step hole is arranged on the table top of the second die sleeve, first die sleeve and the second die sleeve
Table top on further respectively have multiple bolt connecting holes that first die sleeve and the second die sleeve are installed and combined.
Further technical solution: first die sleeve is made of with the second die sleeve 304 stainless steel materials.
The beneficial effects of the present invention are:
(1) present invention constitutes flexible mould by the first die sleeve, the second die sleeve, and the increasing of wire drawing die outer dimension may be implemented
Greatly.One aspect of the present invention is reusable, only needs to change wire drawing die, is conveniently replaceable and saves die sleeve quantity, is conducive to subtract
Few cost.On the other hand due to fixing wire drawing die by Set and Positioning slot, so only needing to change suitable for specification die sleeve of the same race
Wire drawing die, the wire drawing die that a set of die sleeve multiple apertures specification can be realized is generally applicable, realizes that die sleeve utilization rate maximizes, is convenient for
The storage and management of wire drawing die.
(2) the first die sleeve of the present invention and the cone angle on the second die sleeve are conducive to the drawing lubricant in wire drawing and are boring
It smoothly circulates at angle, and takes away the metal powder of drawing process generation, to guarantee the quality of drawn wire product.
(3) present invention realizes the installation and removal of the first die sleeve, the second die sleeve by elasticity bolt, eliminates the big mould of tradition
The process for covering bushing welding, surface treatment, is greatly saved manpower and financial resources, and reduce generation and the row of pollutant
It puts.
(4) raw material of the movable die sleeve of the present invention use 304 stainless steels, and 304 stainless steels have 800 DEG C of high temperature resistant, processing
The feature that performance is good, tensile strength is high, toughness is high, the Ni element contained in material make its good corrosion resistance, and the above feature determines
Durability of this activity die sleeve in drawing process.

Specific embodiment
More specific detail is made to technical solution of the present invention below with reference to embodiment:
As shown in figures 1 to 6: present invention activity die sleeve is installed by the first die sleeve 10 and the second die sleeve 20 to be composed, and described the
One die sleeve 10 is equipped with first step hole 11, and second die sleeve 20 is equipped with the coaxially arranged with the first step hole 11
Two stepped holes 21, the large aperture section in the first step hole 11 is oppositely arranged with the large aperture section in second step hole 21 and common structure
At the Set and Positioning slot a of wire drawing die 30, the small-bore section and the small-bore section structure in second step hole 21 in the first step hole 11
At the wire drawing channel b communicated with wire drawing hole 31 on wire drawing die 30.
The present invention constitutes flexible mould by the first die sleeve 10, the second die sleeve 20, and 30 outer dimension of wire drawing die may be implemented
Increase.One aspect of the present invention is reusable, only needs to change wire drawing die 30, is conveniently replaceable and saves die sleeve quantity, favorably
In reduction cost.On the other hand due to fixing wire drawing die 30 by Set and Positioning slot a, so only needing to change suitable for specification of the same race
The wire drawing die 30 of die sleeve, the wire drawing die that a set of die sleeve multiple apertures specification can be realized is generally applicable, realizes die sleeve utilization rate most
Bigization, convenient for the storage and management of wire drawing die.
The internal diameter of the small-bore section of the small-bore section and second die sleeve 20 of first die sleeve 10 is respectively to far from institute
The direction for stating wire drawing die 30 is gradually increased and forms cone angle beta.First die sleeve of the present invention is conducive to the cone angle beta on the second die sleeve
In wire drawing, drawing lubricant smoothly circulates at cone angle beta, and takes away the metal powder of drawing process generation, to guarantee
The quality of drawn wire product.
First die sleeve 10 and the second die sleeve 20 are in platform-like, and the first die sleeve 10 is arranged in the first step hole 11
On table top, the second step hole 21 is arranged on the table top of the second die sleeve 20, first die sleeve 10 and the second die sleeve 20
Multiple bolt connecting hole c for combining the first die sleeve 10 and the installation of the second die sleeve 20 are further respectively had on table top.This hair
The bright installation and removal that the first die sleeve 10, the second die sleeve 20 are realized by elasticity bolt, eliminate that traditional big die sleeve is bushing, weldering
The process connect, being surface-treated is greatly saved manpower and financial resources, and reduces the generation and discharge of pollutant.
First die sleeve 10 is made of with the second die sleeve 20 304 stainless steel materials.That is the former material of the movable die sleeve of the present invention
Material uses 304 stainless steels, and 304 stainless steels have the characteristics that 800 DEG C of high temperature resistant, processing performance is good, tensile strength is high, toughness is high,
The Ni element contained in material, makes its good corrosion resistance, and the above feature determines durability of this activity die sleeve in drawing process.
