DETAILED DESCRIPTION

[0015] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1~Figure 2 The cable drawing device shown includes a box body 2 through which the power supply line 1 passes, and coaxial wire inlet holes 21 and wire outlet holes 22 are provided on opposite side walls of the box body 2, a drawing die 12 is embedded in the wire inlet hole 21, a guide wheel group 8 and a cooling system are sequentially arranged on the forward path of the wire 1 in the box body 2, a pressurizing component 7 is arranged on the outer side wall of the box body 2 on one side of the wire inlet hole 21, and the wire 1 is subjected to the traction force downstream of the box body 2, and the wire 1 sequentially passes through the pressurizing component 7 and the drawing die 12 in the wire inlet hole 21 into the box body 2, the wire 1 is tensioned and bypassed from the guide wheel group 8, and then passes through the cooling system and passes out from the wire outlet hole 22, and is subjected to the friction resistance of the pressurizing component 7 when being transported forward, so that the wire 1 moves forward stably.

[0017] Specifically, a pressurizing component 7 is installed on one side of the wire inlet hole 21 of the box body 2 through a bracket, which applies a certain pressure to the wire 1, so that there is a certain resistance in the process of the wire 1 moving forward, thereby ensuring the tension on the wire 1. In this way, when the wire 1 is pulled to become thinner and longer, the force is evenly applied during the drawing process of the wire 1, and the drawing process is stable.

[0018] like Figure 1 The guide wheel group 8 is arranged on one side of the box body 2 near the wire inlet hole 21, and includes three guide wheels arranged in a triangle, two of which are distributed on both sides and on the axis of the wire 1, and the third guide wheel is below the two guide wheels with the same water axis. The guide wheel group 8 ensures continuous tension on the transmission path of the wire 1, and stably passes through the transportation path.

[0019] like Figure 1The cooling system is arranged on one side of the box body 2 near the outlet hole 22, and includes a water outlet pipe 5 for cooling, a rubber block 10 for wiping, and an air outlet pipe 3 for drying in sequence. The water outlet pipe 5 and the air outlet pipe 3 are suspended directly above the wire 1. The rubber block 10 is arranged on the axis of the wire 1. A return pipe 9 is arranged below the wire 1 corresponding to the water outlet pipe 5. The wire 1 passes through the middle through hole of the rubber block 10. A return pipe 11 is arranged below the wire 1 corresponding to the air outlet pipe 3. The box body 2 is provided with a water outlet pipe 5, and the water outlet pipe 5 is connected to the water storage tank through a water pump. The water sprayed by the water outlet pipe 5 cools the wire 1, which is conducive to the winding of the wire 1 after drawing. After the water passes through the wire 1, it is collected by the return pipe 9 below to the water storage tank to avoid water resource waste. The rubber block 10 is fixed by the fixing rod 4. The center of the rubber block 10 is provided with a through hole. The diameter of the through hole is slightly smaller than the diameter of the wire 1. After the wire 1 passes through the rubber block 10, the surface water is scraped off. The air outlet duct 3 blows the surface of the electric wire 1 completely dry, and at the same time, the wind is collected by the return air duct 11 below to avoid the air flow in the box 2 and the dust caused by it.

[0020] like Figure 2 The pressurizing assembly 7 includes a pressurizing seat 72, a threading hole 73 is passed through the middle of the pressurizing seat 72 along the axial direction of the electric wire 1, arc-shaped pressing pieces 76 are symmetrically arranged on both sides of the electric wire 1 in the threading hole 73, and the relative outer sides of the two arc-shaped pressing pieces 76 are respectively connected to the push rods 75, and the relative outer ends of the two push rods 75 are respectively connected to the push rod motors 71 for transmission. The two push rod motors 71 are arranged on the two opposite side walls of the pressurizing seat 72, and the two push rod motors 71 respectively drive the two connected push rods 75 to move closer or farther. The threading hole 73 through which the power line 1 passes is arranged in the middle of the pressurizing assembly 7, and the two arc-shaped pressing pieces 76 work together to pressurize the electric wire 1, so that the force on the electric wire 1 is balanced during wire drawing, and rubber pads 74 are installed on the relative inner sides of the arc-shaped pressing pieces 76 to increase the friction force on the electric wire 1.

[0021] Among them, arc-shaped rubber pads 74 are respectively attached to the opposite inner sides of the two arc-shaped pressing pieces 76, and the upper and lower ends of the rubber pads 74 on both sides are fixed in the card slot 77. A pressure sensor is arranged between the rubber pad 74 and the arc-shaped pressing piece 76, and the pressure sensor is connected to the controller and the display 6 at the top of the box body 2. Since the rubber pad 74 is a consumable part, in order to facilitate replacement, a card slot 77 is installed on the arc-shaped pressing piece 76, and the card slot 77 is composed of a bottom plate, a side plate and a back plate. The position of the back plate is located on the side of the forward direction of the wire of the arc-shaped pressing piece 76. Due to the obstruction of the back plate, the rubber pad 74 will not fall out of the card slot 77, and it is convenient for replacement. A pressure sensor is installed between the arc-shaped pressing piece 76 and the rubber pad 74, and the pressure sensor is connected to the controller and the display 6 for displaying and controlling the operation of the push rod motor 71. The controller is provided with a display, and the user can control the pressure of the pressurization through the controller according to the actual use needs.

[0022] The working process of the utility model is as follows:

[0023] As shown in Figures 1-2, first, the wire 1 passes through the pressurizing component 7, passes through the drawing die 12 in the wire inlet hole 21, and then passes around the guide wheel group 8, passes under the water outlet pipe 5, the rubber block 10, and the air outlet pipe 3, and then passes through the wire outlet hole 22. Then, the wire 1 is subjected to the traction force and the resistance of the pressurizing component 7 to ensure a steady speed of advancement. At the same time, the coaxiality of the wire and the drawing die 12 is ensured. After the drawing die 12 on the wire inlet hole 21, it becomes a wire with a reduced diameter.

[0024] The above embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
