[0002] Pointing mills are used to grind and sharpen the ends of metal wires to facilitate the drawing process. However, existing pointing mills lack equipment for fixing the wire, and the wire is generally held by hand for pointing. During the process, the wire needs to be repeatedly inserted into the rollers and rotated 90° back and forth for processing. This results in the processed wire being greatly affected by human error, leading to poor processing quality.

[0003] Chinese Utility Model Patent Application No. CN202320222070.6 discloses a wire tipping mill for precise wire cutting. Its structure includes a roll and a fixing device located at the roll inlet. The fixing device has two perpendicularly intersecting slide rail channels facing the roll. A fixing rod is slidably installed within the slide rail channels. The fixing rod includes a wire channel and a gripping rod, and a screw is installed on the gripping rod for screwing into the wire channel to press the wire within it.

[0004] In this equipment, the wire is positioned and moved by a fixing device and a fixing rod. However, the fixing device is positioned by plugging in, and when changing the rolling position, the fixing device needs to be picked up and put back in, which is quite troublesome. In addition, the wire is positioned by bolts in the fixing rod, and the bolts need to be rotated to clamp the wire during positioning, which is quite time-consuming. Utility Model Content

[0007] As a further scheme of the present utility model: the upper side of the moving table is fixed with a baffle beside the positioning seat, which can prevent the sliding frame from rotating to the left side.

[0008] As a further scheme of the present utility model: the lower side of the pressure head and the inner lower side of the sliding frame are both provided with a limiting groove for fixing the position of the wire.

[0009] As a further scheme of the present utility model: the moving table is provided with a through hole, and a limiting rod is fixed in the through hole between the two supporting plates for limiting the sliding position of the moving table.

[0010] As a further scheme of the present utility model: the sharp rolling machine body comprises two rolling rollers, and the rolling gap between the two rolling rollers is located on the same horizontal line as the limiting groove, so as to facilitate the sharp rolling of the wire.

[0011] As a further scheme of the present utility model: the sharp rolling machine body is electrically connected with an external power supply.

[0012] Compared with the prior art, the present utility model has the advantages that the screw sliding structure is added, the position of the wire can be accurately adjusted, the screw is convenient and fast to adjust, the pressure head structure is added, the wire can be positioned by pressing, and the operation is more convenient.
