Background

The existing metal wire drawing is mostly processed by adopting a diamond wire drawing die, a small hole is arranged in the center of the wire drawing die, a metal wire passes through the small hole to reduce the diameter, the metal wire continuously passes through the plurality of wire drawing dies to complete the drawing of the metal wire, and the original surface needs to be subjected to rust removal before the metal wire raw material is drawn. The traditional derusting method is a chemical method which adopts an acid washing mode (for example, patent No. 201010274104.3, a continuous acid washing and wire drawing process of brass wires) to derust the surface of the metal wire, however, the used waste liquid discharge can affect the environment; also, a more common method of removing rust is a mechanical extrusion or friction method (for example, patent No. 2017114366892, entitled a wire drawing machine pickling-free bending rust removing device), which consumes a lot of electric power, so that the friction wheel rubs the rust layer on the surface of the wire rod, and the method has low rust removing efficiency, high energy consumption and high noise.

The laser rust removal is laser cleaning, and the physical principle can be summarized as follows: the light beam emitted by the laser is absorbed by the rust layer on the surface to be treated, the absorption of the large energy of the rust layer forms a plasma (highly ionized unstable gas) which expands sharply, and then a shock wave is generated, and the rust is broken into fragments and is removed. At present, the laser rust removal technology is mostly used for the rust removal process of plates or other industrial parts, but in the field of metal wire production, the rust removal process still adopts an acid pickling method, so how to apply the laser rust removal technology to a wire drawing machine to realize the rust removal process of metal wires is a problem to be solved urgently.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 2, a high-precision wire drawing machine with a rust removing function comprises a traction roller 1 and a wire feeding roller 2, wherein a wire drawing die 4 for performing a wire drawing process on a metal wire 3 is arranged between the traction roller 1 and the wire feeding roller 2, and a laser rust removing head 5 of a laser cleaning machine is arranged around the metal wire 3 close to an inlet end of the wire drawing die 4.

Preferably, the laser derusting heads 5 are multiple in number and arranged in the same vertical plane at equal angles. Because the cross section of the metal wire 3 is circular, if the positions of the laser derusting heads 5 need to be continuously moved in the derusting process through one laser derusting head 5, a plurality of the laser derusting heads are arranged, the surface of the metal wire 3 can be derusted simultaneously, the whole surface of the metal wire 3 is basically covered, and thus the derusting operation is simpler and the efficiency is higher.

Preferably, the number of the laser derusting heads 5 is 3, and the laser derusting heads are arranged at an angle of 120 degrees in the same vertical plane. In this embodiment, a laser cleaning machine produced by hua-gong laser may be selected, which is composed of an advanced laser, a laser optical system and a control system, and in order to meet the requirements of the cleaning process on the surface of the metal wire (the rust layer on the surface of the metal wire is thin), a laser cleaning machine with a low power of 10 to 100W or a medium power of 150W to 500W may be selected in this embodiment.

Preferably, the laser rust removing head 5 is fixed on the mounting ring 6, the metal wire 3 penetrates through the circle center of the mounting ring 6, and the bottom of the mounting ring 6 is provided with a support frame 7. After the design, the laser rust removing heads 5 of the laser cleaning machine can be well fixed, manual operation is not needed, and the rust removing accuracy and stability are improved; in addition, the laser derusting head 5 is fixed above the mounting ring 6 and can be directly fixed by welding.

Preferably, still be equipped with tensioning roller 8 between wire feeding roller 2 and the laser rust cleaning head 5, the axle hinge at tensioning roller 8 both ends is located U type frame 9 both sides, and U type frame 9 bottom is connected with telescoping device 10 top. Because the metal wire 3 can have lax phenomenon at the feeding in-process, will make the metal wire 3 get into the laser rust cleaning head 5 operation area time straight inadequately like this, can adjust telescoping device 10 at this moment, the structure of electric putter can be chooseed for use to the telescoping device 10 of this embodiment, can drive U type frame 9 and tensioning roller 8 after the telescopic link extension of telescoping device 10 and move up to tighten metal wire 3, make metal wire 3 keep certain rate of tension.

Preferably, a limiting roller 11 is further arranged between the tensioning roller 8 and the laser derusting head 5, and the limiting roller 11 and the traction roller 1 are located at the same height. Because the position of the laser rust removing head 5 is fixed, the metal wire 3 needs to horizontally enter a rust removing operation area of the laser rust removing head 5, the metal wire is horizontally moved through the limiting roller 11, and the stability of the laser rust removing process is ensured.

Preferably, a rust powder collecting groove 12 is further arranged below the mounting ring 6. The rust generated in the laser rust removing process can fall into the rust powder collecting tank 12 to be collected, and no other pollutants are generated in the whole rust removing process, so that the rust removing device is clean and environment-friendly.

The working principle of the embodiment is as follows:

when the wire drawing machine works, the driving motor drives the traction roller 1 to rotate, so that the wire feeding roller 2 stably feeds the metal wire 3 into the wire drawing die 4, the laser cleaning machine is started, the laser emitted by the laser rust removing heads 5 irradiates the surface of the metal wire 3 together, the metal wire 3 is removed while moving, and the metal wire 3 after rust removal enters the wire drawing die 4 for wire drawing; the rust powder produced in the process falls into the rust powder collecting tank 12 to be collected, and no other pollutants are produced in the whole rust removing process, so that the rust removing tank is clean and environment-friendly.
