Description

Technical Field

[0001] The present application relates to the technical field of steel ball manufacturing, and more specifically to a wire drawing component of a steel ball manufacturing device. Background Art

[0002] In the steel ball preparation process, it is often necessary to use a wire drawing assembly to draw the steel wire used to make the steel ball. Under the action of external force, the steel wire is forced through the die for drawing, and the cross-sectional area of ​​the steel wire is compressed, so that the cross-sectional area shape and size of the steel wire meet the processing requirements. The existing wire drawing assembly is generally composed of a wire drawing seat and a die installed on the wire drawing seat. During the drawing process, the steel wire will generate sliding friction with the die, which makes the steel wire plastically deform unevenly in the die, and generates a large amount of heat, increasing the consumption of drawing energy. Therefore, wire drawing lubricating powder is often contained in the wire drawing seat to reduce the sliding friction between the steel wire and the die. When drawing, the steel wire is first passed through the wire drawing seat, so that the steel wire is adhered to the wire drawing lubricating powder and then processed by the die. In the actual wire drawing process, the wire drawing lubricating powder near the die is coked due to the influence of high temperature for a long time, and a relatively solid block will be formed to cling to the entrance, so that the lubricating powder cannot be brought in when the steel wire is drawn and the lubricating effect is lost. In view of the above problems, a utility model patent with publication number: CN208245470U discloses a wire drawing die box for reducing the coking of lubricant powder, including a base arranged on a drawing machine, a wire drawing die is installed on one side of the base, a lubricant powder box is arranged in the base, a driving motor is arranged at the lower end of the base, a rotor of the driving motor penetrates into the lubricant powder box and is connected to a stirring seat, and a plurality of stirring blades are arranged in a circumferential direction of the stirring seat; the technical solution continuously stirs the lubricant powder in the lubricant powder box by the stirring blades, so that the lubricant powder The lubricating powder in the box dissipates heat evenly, and the stirring blades can also break up some of the dried lubricating powder to prevent the lubricating powder from coking. However, this solution provides a discharge valve at the lower end of the base. The lubricating powder in the lubricating powder box can be replaced in batches by opening the discharge valve. The provision of the discharge valve deteriorates the integrity of the base, and the lubricating powder easily clogs the discharge valve. The opening and closing of the discharge valve is relatively laborious. On the other hand, the discharge valve is small in size, and cleaning the lubricating powder is relatively time-consuming and laborious. Therefore, a wire drawing component that can quickly clean the lubricating powder is currently needed. Utility Model Content
