Example (b):
as shown in fig. 1 and 2, the present invention provides a copper wire drawing machine, which comprises a drawing machine body 1, a die 2 and a heating member 3. The drawing machine body 1 includes various components of the drawing machine. This part is not within the scope of protection of the present application and is not described in detail in the specification. The heating part 3 is arranged on the wire drawing machine body 1 and is positioned in front of the die 2, so that the copper wire 6 passes through the die 2 after being heated by the heating part 3. The heating part 3 may be in various forms such as an electric heating tube or a flame heating, etc.
When the copper wire drawing machine of the present invention is used, the heating member 3 heats and softens the copper wire 6. At this point, the copper wire 6 is passed into the die 2 for extrusion. After the copper wire 6 is softened, it is more easily crushed. So that the copper wires 6 are subjected to less pressing force. This also allows the copper wire 6 to be drawn through the die 2 and extruded into a thinner copper wire 6 with less pulling force. Effectively avoid the wire drawing in-process to lead to copper line 6 to be broken because of the pulling force is too big.
In the present embodiment, the heating member 3 is a high-frequency electromagnetic heater. The main body of the high-frequency electromagnetic heater is an annular conductor. The copper wire 6 passes through a ring-shaped high-frequency electromagnetic heater and then enters the die 2. High-frequency current is introduced into the high-frequency electromagnetic heater, so that a high-frequency variable magnetic field is generated around the high-frequency electromagnetic heater. The portion of the copper wire 6 passing through the heating member 3 is heated by generating an eddy current by the high-frequency magnetic field. Adopt high frequency electromagnetic heater to heat can be quick to copper line 6 heat for wire drawing speed can suitably improve. Meanwhile, the magnetic field generated by the high-frequency electromagnetic heater only has an effect on the close metal, so that the surrounding nonmetal is not heated, and the safety is high.
In this embodiment, the pressure sensor 4 and the control unit are further included. The pressure sensor 4 is arranged at one end of the mould 2 remote from the heating member 3. As the copper wire 6 passes through the die 2, the copper wire 6 exerts a large pressure on the die 2. The mold 2 transmits the pressure to the pressure sensor 4, thereby enabling the pressure sensor 4 to detect the current pressure level of the mold 2. The pressure sensor 4 and the heating member 3 are both connected to the control unit. The control unit controls the output power of the heating member 3 based on the monitoring data of the pressure sensor 4.
When in use, the parameter values of the control unit are preset. When the pressure applied to the die 2 is greater than the set value, the control unit controls the output power of the high-frequency electromagnetic heater to be increased, so that the temperature of the copper wire 6 is increased, and the copper wire 6 becomes softer. At this moment, the thrust that copper line 6 produced mould 2 through mould 2 will reduce, and then effectively avoid copper line 6 to be broken. When the pressure to which the die 2 is subjected is more than a proper value, the control unit controls the output power of the high-frequency electromagnetic heater to be maintained at a proper value so that the tension of the copper wire 6 is in a constant state.
The output power control method of the high-frequency electromagnetic heater generally includes the following three kinds: (1) frequency Modulation (PFM). The frequency modulation method is to adjust the switching frequency of the inverter switching tube, so as to change the output impedance to achieve the purpose of adjusting the output power. (2) Pulse Density Modulation (PDM). The PDM controls the output average power by controlling the pulse density, so as to achieve the purpose of controlling the power. (3) Pulse Width Modulation (PWM). PWM adjusts output power by adjusting the conduction time of the inverter switch tube in one period.
In this embodiment, an extruding member 5 is further provided between the heating member 3 and the die 2 in cooperation with the copper wire 6. The extrusion 5 is used to pre-extrude the heated copper wire 6. So that the copper wire 6 is squeezed down before entering the die 2, reducing the pulling force required for the copper wire 6 to pass through the die 2.
In the present embodiment, the pressing member 5 includes a slide rail 51 and a slider 52 fitted to the slide rail 51. The slider 52 can move along the slide rail 51 toward or away from the heating member 3. The slide rail 51 is provided obliquely to the copper wire 6 so that the slider 52 can abut against the copper wire 6 when the slider 52 moves away from the heating member 3. A magnet 53 is provided on the side of the slider 52 close to the heating member 3.
When the magnetic slide rail is used, the high-frequency magnetic field generated by the heating component 3 acts on the magnet 53, so that the magnet 53 drives the slide block 52 to reciprocate along the slide rail 51 under the action of the magnetic force. As the slider 52 moves away from the heating member 3, the slider 52 gradually approaches and hits the copper wire 6. This causes the copper wire 6 softened by heating to be deformed and tapered by the high-frequency impact of the slider 52. Thereby realizing the pre-extrusion effect. Thereby reducing the pulling force required to move the copper wire 6 through the die 2. Meanwhile, each time the slider 52 strikes the copper wire 6, the force applied to the copper wire 6 by the slider 52 has a component force that pushes the copper wire 6 to move toward the mold 2. This enables the slider 52 to advance the copper wire 6. The copper wire 6 is fed to the die 2 under the combined action of pushing and pulling forces. So that the pulling force on the copper wire 6 is reduced, and the copper wire 6 is more effectively prevented from being broken.
The frequency of the reciprocating motion of the slider 52 may be affected by the mechanical structure, resulting in that the vibration frequency of the slider 52 cannot be increased infinitely. Meanwhile, when the vibration frequency of the slide block 52 reaches a higher value, the striking force of the slide block 52 per time is correspondingly reduced. In this embodiment, the power of the high-frequency electromagnetic heater is controlled by pulse width modulation. The heating is an intermittent heating method. The copper wire 6 is heated to a high temperature by a high-frequency magnetic field in a short time. Subsequently, the frequency of the magnetic field of the high-frequency electromagnetic heater is lowered so that the slider 52 can effectively hit the copper wire 6 at an appropriate frequency.
In the present embodiment, the extrusion 5 is provided in several groups. Several groups of extrusions 5 are evenly distributed around the copper wire 6. This makes the forces experienced by the copper wire 6 in all directions more uniform.
In this embodiment, the heating member 3 is spirally provided with a plurality of turns. This makes the length of the copper wire 6 covered by the heating member 3 longer, the heated portion more, and the heating effect more stable. Meanwhile, the more the number of turns of the heating part 3 is, the stronger the generated magnetic force is, and the greater the striking force of the slider 52 to the copper wire 6 is. The copper wire 6 is pre-extruded more effectively.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
