A kind of Wire drawing die box device that prevents that the ring steel wire from producing comprises the deformed area that lubricated district is connected with described lubricated district, wherein, the tuning arm of tension force also is set is connected with described lubricated district, is used for adjusting the tension force between each passage.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, the tuning arm of described tension force and steel wire are set, and to be tangent line crossing.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, the tuning arm of described tension force lower end arranges tension pick-up, for detection of being uploaded to Programmable Logic Controller behind the tension signal between each mould passage.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, described Programmable Logic Controller calculates cumulative adjustment amount by PID, to keep constant tension between each passage.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, described deformed area arranges circulating cooling system, prevents from causing strain-aging.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, described circulating cooling system is comprised of water inlet and gap.

The described Wire drawing die box device that prevents that the ring steel wire from producing wherein, arranges mobilizable screw thread mounting in the described deformed area, be used for preventing the Bamboo-shaped steel wire.

The described Wire drawing die box device that prevents that the ring steel wire from producing wherein, also arranges pressure roller and is connected with described deformed area, is used for preventing the Bamboo-shaped steel wire.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, the described mobilizable screw thread mounting that arranges in when described steel wire enters described deformed area via described lubricated district is then by described pressure roller.

The described Wire drawing die box device that prevents that the ring steel wire from producing, wherein, described pressure roller increases downward pressure by described steel wire.

Adopt technical scheme of the present invention, can effectively avoid the skidding that causes in the tension test, thereby guaranteed that the stress-strain tester data discrete is little, clamping is reliable, and be not prone to skidding, this apparatus structure is succinct, efficient, can solve number of drawbacks and deficiency that existing Wire drawing die box production exists.
