Description
Technical Field
The invention belongs to the field of copper wire processing, and particularly relates to a copper wire vibration wire drawing device and process for reducing annealing energy consumption.
Background
The drawing of copper wires goes from the earliest 'earth drawing machine' to the current high-speed drawing machine and then to a multi-head drawing machine, and develops towards high speed, multi-head and high efficiency. However, in the process of wire drawing, wire breakage and surface defects are likely to occur due to severe deformation and large deformation force and friction force.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a copper wire vibration wire drawing device and a process, which can reduce the amplitude of tension adjustment, effectively reduce uneven deformation, improve the appearance of the outer surface of a copper wire and enable the wire drawing process to be more stable.
In order to achieve the purpose, the invention adopts the following technical scheme: a copper wire vibration drawing device comprises: an ultrasonic driver, a wire drawing direction vibrator, a vertical vibrator, a wire drawing die and a drawing tractor,
one end of the copper wire is connected with a drawing tractor and is extruded and deformed by a drawing die, the drawing direction vibrator and the vertical vibrator are orthogonally connected and then fixedly connected with the side wall of the drawing die, the ultrasonic driver respectively drives the drawing direction vibrator and the vertical vibrator to drive the drawing die to vibrate ultrasonically,
the wire drawing direction vibrator and the vertical vibrator respectively comprise a rear end cover, a front end cover and an amplitude transformer, an ultrasonic driver is arranged between the rear end cover and the front end cover, the front end cover is fixedly connected with the amplitude transformer, the axis of the amplitude transformer of the wire drawing direction vibrator is the same as the wire drawing direction, and the front ends of the amplitude transformers of the wire drawing direction vibrator and the vertical vibrator are vertically connected to the wire drawing die.
Further, the ultrasonic driver is piezoelectric ceramic.
Further, the lengths of the amplitude transformer of the wire drawing direction vibrator and the amplitude transformer of the vertical vibrator reach a resonance condition.
Furthermore, the front ends of the amplitude transformer of the wire drawing direction vibrator and the vertical vibrator are arranged on the side wall of the wire drawing die through screws and a pressing plate.
Further, in order to ensure close contact between the die and the front end of the horn, the die side walls are coated with a lubricant. Therefore, the wire drawing die can be ensured to be in close contact with the rear end cover and the front end of the amplitude transformer, and energy can be effectively transferred.
Correspondingly, the copper wire vibration wire drawing process comprises the following steps:
during wire drawing, the ultrasonic driver performs vertical and transverse vertical composite ultrasonic vibration on a wire drawing die, the wire drawing speed is 980mm/s, the drawing force of a drawing tractor is 24N, and THS-1 composite lubricant is adopted;
the frequency that ultrasonic driver vibrated is 21.43kHz, power input voltage is 400V, and output current is 0.5A, and the amplitude of wire drawing direction vibrator is 18um, and the amplitude of perpendicular vibrator is 15 um.
The working principle of the invention is as follows:
for ultrasonic machining, the distal end of the horn is often required to have a large amplitude of vibration, which requires the horn to have as large a form factor and magnification as possible. In order to change the condition, two perpendicular amplitude transformer rods are needed to make up the deficiency so as to improve the output performance, and the length of the amplitude transformer rods must meet the resonance condition. When the two ultrasonic drivers work simultaneously, the wire-drawing die has the advantages of longitudinal vibration and transverse vibration during wire drawing. And at the center of the wire-drawing die, the ultrasonic vibration is strengthened at the intersection of the two 1.5-time wavelengths. At the moment, the center of the drawn metal deformation has a complex stress state, so that the plasticity of the wire is more effectively influenced by the ultrasound.
The invention has the beneficial effects that:
the vertical composite vibration device and the process disclosed by the invention can effectively prolong the tension regulation period of the wire drawing machine. The effect of improving the uneven deformation and stabilizing the wire drawing process is obvious. The method has considerable economic benefit for the production of copper wire drawing, reduces repeated die penetration caused by wire breakage, and saves a large amount of manpower and material resources.
