Embodiment 1

[0028] A method for drawing a metal rod. The metal rod is soaked in liquid lubricating oil for drawing, and the metal rod is extruded and sized at the oil outlet to obtain a metal wire with a smooth surface; the metal rod is an aluminum rod. The drawing speed is 45-50m / min, and the diameter after sizing is 6-18mm.

[0029] The flat tug wheel group, crimping wheel and wire clamping wheel group guide the aluminum wire into the fuel tank smoothly, and ensure that the metal rod penetrates the drawing die horizontally. The aluminum wire passes through the drawing die group to complete the extrusion and sizing of the metal rod, and the aluminum wire is wound on the On the reel, rely on the pulling force of the reel to guide the aluminum wire through the drawing die set to achieve drawing and sizing. Quick change of molds can be realized by cylindrical fastening bolts.

[0030] The present invention can also be used for copper wire drawing, and can be used as a separate aluminum rod...

Abstract

The invention relates to a metal rod drawing device and method. The metal rod drawing device includes a fuel tank, and the fuel tank is provided with a flat tugwheel group for incoming wires, a crimping wheel and a wire clamping wheel group, and a flat tugwheel group and a wire clamping wheel group. Set vertically, the crimping wheel is in the fuel tank, set parallel to the flat tug wheel group, the fuel tank is also equipped with a drawing die set for the outgoing line, the outgoing line is wound on the drawing reel, and the drawing reel is connected to the motor through the reduction box. The drawing die set includes a drawing die, a cylindrical joint at one end of the drawing die, the cylindrical joint is socketed with a cylindrical fastening bolt, and the cylindrical fastening bolt is connected to the mold base through its external thread, The mold holder is fixed on the fuel tank. The metal rod is soaked in liquid lubricating oil for drawing, and the metal rod is extruded and sized at the oil outlet to obtain a metal wire with a smooth surface. The surface finish of the drawn aluminum wire is higher, and the raw material is simple and the cost is low.

Description

technical field [0001] The invention relates to a drawing device and method, in particular to an aluminum rod drawing device and method. Background technique [0002] Aluminum rod drawing, commonly used calcium-based grease and 10% to 20% animal and vegetable oils and soap lubricants, sprayed on the surface of the aluminum rod for drawing. The lubricating effect is poor, and the surface quality of the aluminum wire after drawing is poor. The lubricating oil needs to use a special lubricant, and the cost is high. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a metal rod drawing device and method, the drawn metal wire has a higher surface finish, and the raw material is simple and the cost is low. [0004] A pulling device for a metal rod, including a fuel tank, on which are provided a flat tug wheel group, a wire clamping wheel group and a crimping wheel, the flat tug wheel group and the wire clamp...
