Cutting and forming device of screw forming machine

Abstract

The invention relates to a cutting and forming device of a screw forming machine. The cutting and forming device comprises a rack, wherein a cutting knife, a cutting mechanism, a forming mould and a mould closing mechanism are arranged on the rack; the cutting mechanism drives the cutting knife to cut a wire; the mould closing mechanism drives the forming mould to close; a cutting edge of the cutting knife is equipped with a cutting edge slot which is adaptive to the periphery of the wire in shape and a limiting mechanism for limiting the wire into the cutting edge slot; a moving track, driven by the cutting mechanism, of the cutting knife is equipped with a cutting station and a processing station; the cutting station corresponds to the position of a wire feeding device; and the processing station corresponds to the position of the forming mould. With the adoption of the scheme, the invention provides the cutting and forming device, which simplifies the structure and improves processing efficiency, of the screw forming machine.

Description

technical field [0001] The invention specifically relates to a screw forming machine, in particular to a cutting and forming device of the screw forming machine. Background technique [0002] Screw forming machine is a forging and forming equipment that thickens the top of bar or wire at room temperature. It is a special equipment mainly used for mass production of fasteners such as nuts and bolts. The screw forming machine adopts the method of cold heading to upset the heads of bolts and screws, which can minimize the cutting work and directly form them into the required shape and size, which can not only save a lot of materials, but also greatly improve production efficiency and significantly improve Mechanical strength of the part. [0003] The processing steps of the screw forming machine generally consist of a wire feeding device, a cutting device, a forming device and a discharging device. The wire feeding device transfers the coiled wire to the cutting device, and th...

AI Technical Summary

Problems solved by technology

[0004] Among them, the cutting device includes a cutting knife and a cutting drive mechanism that drives the cutting knife to cut, and the forming device includes several forming molds and a clamping mechanism, and the clamping mechanism transfers the cut linear materials between the forming molds in sequence , which are extruded and formed by each mold in turn. The traditional cutting device and forming device are two independent devices, which not only increases the space occupied by the equipment and the complexity of the device, but also prolongs the processing stroke of the wire and reduces the processing efficiency.
