Description
Technical field
The present invention relates to a kind of drawing mould, belongs to tinsel production equipment technical field.
Background technology
At present, to production wiry, frequently with drawing production process, will tinsel pass sequentially through multiple apertures gradually
The drawing mould of reduction, the size so as to be gradually lowered diameter wiry, needed for obtaining.Produce high-carbon steel wire when
Wait, need to reduce every time compression ratio, so as to prevent high-carbon steel wire to be layered, improve the toughness and fatigue durability of high-carbon steel wire
Energy.However, sub-quantity must be increased if reducing every time compression ratio, while also need to reduce cone pulley speed, this
Result in produce same thickness it is wiry when, it is very big to increased the production time, cause production efficiency to reduce.Thus,
It is badly in need of a kind of toughness and fatigue performance that both can ensure that the high-carbon steel wire after drawing, while and being unlikely to reduce production efficiency
Drawing mould.
The content of the invention
For this purpose, the technical problem to be solved is to ensure the toughness of high-carbon steel wire and resistance in prior art
Fatigue behaviour needs the technical problem for reducing production efficiency, so as to propose a kind of both to have can ensure that the tough of the high-carbon steel wire after drawing
Property and fatigue performance, while and be unlikely to reduce production efficiency drawing mould.
To solve above-mentioned technical problem, a kind of drawing mould of the present invention, including diaphragm capsule support, it is arranged on diaphragm capsule support
Several first diaphragm capsules for setting in a row, and the second diaphragm capsule, tinsel passes sequentially through and pass through again after each first diaphragm capsule second
Diaphragm capsule completes metal wire drawing, the second diaphragm capsule and tinsel finally by the first diaphragm capsule be set up in parallel and the second diaphragm capsule and gold
Category silk finally by the drawing aperture of the first diaphragm capsule be coaxially disposed;
The drawing aperture includes the entrance, compression section, profiled section and the outlet section that are sequentially communicated, the diameter of entrance towards
Dimension linear near compression section reduces, and the diameter of compression section towards the dimension linear near profiled section reduces, profiled section it is straight

The drawing mould of the present invention, the length of outlet section is 1 with the ratio of shaping segment lenght:5-1:10.
Preferably, the length of outlet section and the ratio of shaping segment lenght are 1:6.
The drawing mould of the present invention, the first diaphragm capsule is divided into some groups for setting in a row, one group of the formation per 4-8, per group the
One diaphragm capsule is separately positioned on a diaphragm capsule support.
The drawing mould of the present invention, the first diaphragm capsule is 21-25.
The above-mentioned technical proposal of the present invention has compared to existing technology advantages below:
(1) drawing mould of the invention, drawing aperture is arranged entrance, compression section, profiled section and the outlet being sequentially communicated
Section, entrance and outlet section each serve as importing and derive effect wiry, and tinsel produces deformation, diameter quilt in compression section
Compression, and maintains the size after compression section by the constant profiled section of diameter, it is ensured that tinsel through each first
The size after deformation quantity and deformation during diaphragm capsule.In addition, with can make the larger deformation quantity of tinsel the first diaphragm capsule most
Afterwards, the second diaphragm capsule for making tinsel produce little deformation quantity is set, and the first diaphragm capsule is produced compared with large deformation to ensure production efficiency, is being drawn
The final stage pulled out, control tinsel produces little deformation quantity, so as to avoid very high strength layering wiry, improves metal
The toughness and fatigue behaviour of silk.Thus the drawing mould of the present embodiment can be in the case where production efficiency be ensured, moreover it is possible to improve
Toughness wiry and fatigue behaviour.
