Wire drawing machine for precision screw production

Abstract

The invention discloses a wire drawing machine for precision screw production. The wire drawing machine comprises a reciprocating mechanism, a wire drawing mechanism and a wire conveying mechanism, wherein the reciprocating mechanism is internally provided with the wire drawing mechanism, the wire drawing mechanism is internally provided with the wire conveying mechanism, the reciprocating mechanism comprises a bottom plate, a top plate, supporting rods, a transverse sliding groove, a first motor, a fixing rod, a connection pin, a movable rod and a rotating sleeve, the top plate is arranged above the bottom plate, the four supporting rods are fixedly connected between the bottom plate and the top plate, the transverse sliding groove is formed in the top plate, the first motor is fixed to the lower side of the top plate through a screw, and the output end of the first motor penetrates through the top plate to be fixedly connected with the fixing rod. The wire drawing machine for precision screw production has the characteristics of being reasonable in structural design and high in machining efficiency, the conveying efficiency of a wire is greatly improved by adopting the mode of combining the reciprocating mechanism and the wire conveying mechanism when the wire drawing machine is used, meanwhile, an air cylinder is arranged so that a driving wheel can compress the wire, and the phenomena of slipping and the like of a traction wheel can be effectively avoided.

Description

technical field [0001] The invention relates to a thread drawing machine, in particular to a thread drawing machine for precision screw production, which belongs to the technical field of screw processing. Background technique [0002] The wire used for screw production needs to be pickled before drawing, which can remove the oxide film on the surface of the wire and form a phosphate film, which can minimize the damage to the mold caused by rough wire and sundries. After pickling, the wire must be cooled by a wire drawing machine Pull to the desired radius and then cut to make the stud into a nail blank. [0003] Existing wire drawing machines for screw production mostly use traction wheel transmission for wire transmission. In order to ensure the accuracy of the cutting length, the speed of the traction wheel for wire shearing is relatively slow. When cutting a long length of wire post, the wire The output efficiency is low, which makes the processing efficiency of the wir...

Problems solved by technology

[0004] The object of the present invention is to provide a wire drawing machine for precision screw production in order to solve the above problems, which solves the problem that the existing wire drawing machine for screw production usually uses a traction wheel transmission mode to carry out wire transmission, and intercepts longer lengths of wire. When the column is used, the output efficiency of the wire is low, which makes the processing efficiency of the wire drawing machine low.
