At this time, the metal wire needs to be cut manually with pliers. Since the temperature of the metal molecules is high after stretching and extrusion, the metal wire loses its traction after cutting and is easy to swing left and right, causing burns to the workers' hands. For this reason, we propose a coated wire drawing die. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See also Figure 1-Figure 4 A coated wire drawing die shown in the figure includes a wire drawing die body, a sealing fitting ring 4 is installed on the outer periphery of the wire drawing die body 1 in a sealing manner, a cooling channel 5 is constructed between the inner periphery of the sealing fitting ring 4 and the outer periphery of the wire drawing die body 1, and both ends of the cooling channel 5 are respectively connected to joints fixed on the outer periphery of the sealing fitting ring 4, and the joints are respectively connected to a cold water pipe 6 and a return water pipe 7, both of which are connected to a cooling box 8, and a connecting rod 2 is symmetrically arranged on the side wall of the wire drawing die body 1, and a cutting assembly 3 is fixed between the ends of the connecting rod 2.

[0027] The actual length of the connecting rod 2 can be adjusted according to production conditions to control the distance between the cutting assembly 3 and the drawing die body 1 within a suitable range.

[0028] Furthermore, the cutting assembly 3 includes a fixing ring 31 fixed between the ends of the connecting rod 2, a limit frame 32 symmetrically arranged about the circular hole of the fixing ring 31 is fixed to the side wall of the fixing ring 31, a low-speed motor 33 is fixed to the end of the limit frame 32, the end of the low-speed motor 33 is transmission-connected to a screw rod 34 located inside the limit frame 32, a limit block 35 slidably attached to the inner wall of the limit frame 32 is threadedly connected to the outer periphery of the screw rod 34, and a connecting frame 36 located outside the screw rod 34 and extending to the outside of the limit frame 32 is fixed to the side wall of the limit block 35, and a cutting strip 37 is fixed to the end of the connecting frame 36.

[0029] When the low-speed motor 33 rotates, it drives the screw rod 34 and the limit block 35 to rotate relative to each other, causing the limit block 35 to move horizontally in contact with the inner wall of the limit frame 32. The movement of the limit block 35 drives the connecting frame 36 and the cutting strip 37 at the end of the connecting frame 36 to move horizontally. During the movement of the cutting strip 37, the spacing changes to extrude and cut the metal substrate.

[0030] Furthermore, a plurality of heat sinks 9 are provided on the top of the cooling box 8 at equal intervals, the bottom of the heat sink 9 extends to the bottom surface of the cooling box 8, the top view cross-section of the heat sink 9 is in the shape of a U, the cooling channel 5 is in a spiral shape, the side wall of the cooling box 8 is provided with scale lines 11 for conveniently checking the height of the liquid level inside the cooling box 8, the top of the cooling box 8 is provided with a water inlet, and a water inlet end cover 10 is swung around the water inlet.

[0031] Under the action of the spiral cooling channel 5, it is convenient to control the unidirectional flow of cooling water in the drawing die 1, and heat exchange is performed on the drawing die 1 and the metal substrate whose temperature rises after passing through the drawing die 1 to reduce their temperature. At the same time, the temperature of the water returning to the cooling box 8 can be reduced through the heat sink 9 to maintain the cooling water in a lower temperature range.

[0032] It should be noted that the utility model is a coated wire drawing die. When in use, after the metal substrate passes through the wire drawing die body 1, it is restricted by the inner cavity of the wire drawing die body 1 to form a thinner metal wire. Due to the collision of molecules inside the metal substrate, the metal substrate and the wire drawing die body 1 are heated together. Subsequently, under the action of the water pump in the cooling box 8, the cooling water is transported to the cooling flow channel 5 through the cold water pipe 6, and flows back from the return water tank to the cooling box 8. In this process, heat exchange is carried out with the wire drawing die body 1 and the metal wire, reducing The temperature of the wire drawing die 1 and the metal wire is controlled by the circuit to start the low-speed motor 33 when the drawn metal wire needs to be cut. When the low-speed motor 33 rotates, it drives the lead screw 34 and the limit block 35 to rotate relative to each other. The limit block 35 moves horizontally in contact with the inner wall of the limit frame 32. The limit block 35 drives the connecting frame 36 and the cutting strip 37 at the end of the connecting frame 36 to move toward the outer periphery of the metal wire until the metal wire is cut off, effectively avoiding the metal wire breaking point swinging left and right when the metal wire is cut manually, which may burn the worker's hands.
