Embodiment 1
[0051] In this embodiment, the diameter of the sizing hole 5 of the sizing die 4 is Φ2.00mm, the diameter of the powder coating hole 3 is Φ2.80mm, and the diameter of the diversion hole is Φ2.00mm. Install the mold body 1 on the sizing mold 4. After the installation is completed, put the incoming wire and wire drawing powder with a diameter of Φ2.00mm into the mold body 1 from the trumpet-shaped wire inlet of the powder coating hole 3 at the same time. When moving along the trumpet-shaped wire inlet of the powder coating hole 3 to its wire outlet, because a large amount of heat will be generated during the wire drawing process, the wire drawing powder will become a fluid lubricant and force the surface of the wire to be fully lubricated. In order to ensure the lubrication effect, when the incoming wire passes through the outlet of the powder coating hole 3 and enters the cavity, in order to avoid the carbonized lubricant contacting the surface of the incoming wire again under t...

Abstract
The invention relates to the technical field of wire preparation, in particular to a forced powder coating mold which comprises a mold body. The wire outlet end of the die body is connected with the wire inlet end of a sizing die, a cavity for discharging carbonized lubricant is defined, a powder coating hole for coating powder and lubricating an inlet wire is formed in the die body, a wire outlet of the powder coating hole is connected with the wire inlet end of the cavity, and the wire outlet of the powder coating hole is connected with the wire inlet end of the cavity. A cavity is formed in the mold body, a wire inlet end of the sizing mold is connected with a wire outlet end of the cavity, a plurality of flow guide holes are further formed in the mold body, and flow inlets of the flow guide holes are connected with the wire inlet end of the cavity so as to be used for discharging carbonized lubricating agents. In practical application, based on the trumpet-shaped wire inlet of the powder coating hole and the multiple flow guide holes of the die, the powder coating lubricating effect of the surface of a wire is effectively guaranteed, meanwhile, a carbonized lubricant can be discharged from the flow guide holes, and the die has the advantages of being easy and convenient to operate, good in powder coating lubricating effect and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of wire material preparation, in particular to a forced powder coating mold. Background technique [0002] In actual production, the coating effect of the lubricant (drawing powder is fluid at high temperature) during the wire drawing process is usually directly related to the surface quality of the wire and the service life of the mold. In the prior art, there are usually two methods for the surface lubrication of the drawn wire. Method 1: use a wheeled metal clamp as a powder coating die; The same type of mold as a powder coating mold. Although these two methods can improve the smearing effect of the lubricant to a certain extent, due to certain defects, they cannot meet the requirements of high-quality lubrication and high-efficiency production of wire materials. Method 1: When using the wheel-type metal clamp, the problem that the wheel-type metal clamp bearing is caught in the wire drawing powder and ...
