Abstract

The utility model provides a composite processing device for the heat treatment and the straightening of the steel wire, comprising a tension device. The utility model is characterized in that the utility model also comprises an electric heater which is composed of two bearing racks, two electrical contacts and a low-voltage heavy-current transformer, and a cooling fluid spraying pipe; the electrical contacts are a pair of double rollers which is opened with steel wire grooves in the middle, driven by an adjustable speed motor, a reduction box and a pair of meshed gear wheels, and arranged on the two bearing racks; a power output end of the low-voltage heavy-current transformer is separately connected with the two bearing racks; the cooling fluid spraying pipe is disposed on the upper part of the back end of the electric heater; and the tension device is arranged on the back end of the cooling fluid spraying pipe. The utility model uses the electricity to directly heat the steel wire, and carries on the heat treatment and the straightening under the thermal state. Thereby, the utility model has the advantages of having good adaptability, small deformation, high precision, simple structure, easy operation and good stability, being able to improve the physical property of the steel wire, and the like. Moreover, the utility model is applicable to various steel wires to carry on the straightening and the heat treatment simultaneously.

Description

Steel Wire Heat Treatment and straightening complex machining device

Affiliated technical field

The utility model relates to metal-working plant, particularly a kind of Steel Wire Heat Treatment and straightening complex machining device.Being fit to metal machining factory adopts.

Background technology

In prior art, the production of steel wire is serialization, generally all is rolled into plate-like supply applying unit through rolling the steel wire of delaying, and applying unit must will could be used after its straightening, and some steel wire also will improve its physicals through Overheating Treatment.Relatively ripe for the straightening technology of rounded section steel wire, but still have very big difficulty for the straightening of special crosssection steel wire, frock complexity not only, and be difficult to reach conforming effect.Injure the surface of steel wire in addition easily.Though the tension force straightening is a kind of method of steel wire straightening, this method only is fit to the straightening of light gage wire, should not be used for the thick steel wire or the steel wire of noncircular cross section, therefore has significant limitation.

Summary of the invention

But the purpose of this utility model is to provide the steel wire of various cross-sectional shapes of a kind of wide adaptability straightening and size, and can heat-treat Steel Wire Heat Treatment and the straightening complex machining device that improves the steel wire physicals to steel wire simultaneously.

Task of the present utility model realizes by this way: this device includes one by support, the two rollers and the torque motor that have steel wire trough constitute tension device, it is characterized in that also having an electric heater and a cooling fluid shower, electric heater is by two bottom brackets, two electrically contact contact and a low-voltage high-current transformer formation, two distances are no less than 1 meter bottom bracket at least and are arranged on the ground, electrically contacting contact is two rollers that a pair of centre has steel wire trough, by adjustable speed motor, the gear driven of reduction box and pair of meshing rotates, two two rollers that electrically contact contact are arranged at respectively on the dead eye of two bottom brackets, low-voltage and high-current variable-voltage power supply output terminal is connected with two bottom brackets respectively, have the top that vertically be arranged at electric heater rear end of the cooling fluid shower of several mouth sprays along two bottom brackets, entrance end at its cooling fluid is provided with a valve, and tension device is arranged at the ground of the rear end of cooling fluid shower.

The purpose of this utility model also can take following measure to realize:

On electrically contacting steel wire heating section between the contact, two of electric heaters also are provided with a thermal insulation casing, to reduce thermosteresis.

The voltage that electric heater adopted is the 20-70 volt, and electric current is the 100-500 ampere, guaranteeing the security and the operability of production process, and supports the impact to electrical network.

Such work of the present utility model: discous steel wire is pulled out, allow it pass two couples contact roller of electric heater, steel wire after the energising heating is by cooling fluid shower below, sharply thermal treatment has been carried out in cooling under the cooling fluid spray of ejection, pulls it to cut to the cutting machine through a pair of roller of tension device at last and cuts.Because the utility model is to utilize electricity directly steel wire to be heated and carry out straightening and thermal treatment under hot, therefore, compared with the prior art has following advantage:

But the steel wire in the different steel grades of 1 straightening, different size and cross section, adaptability is good, and is indeformable, straightening precision height.

2, in straightening, can comprise annealing, scold fire, solid solution and thermal treatment such as modified, improve the physicals of steel wire steel wire.

3, fairly simple, the easy operation of device of the present invention, good stability, easy to utilize.
