Pre-deformation bending pressure head device based on physical properties of red copper wire

Abstract

The invention discloses a pre-deformation bending pressure head device based on physical properties of a red copper wire. The pre-deformation bending pressure head device structurally comprises a bottom plate, a rail, a supporting plate, a motor, a side plate, a screw rod, a pre-deformation bending clamping mechanism, a bobbin rack, a copper wire bobbin and a winding drum lock frame, wherein the supporting plate is welded to the right end of the lower surface of the bottom plate; the rail is embedded into the middle section of the upper surface of the bottom plate; the side plate is welded tothe right end of the upper surface of the bottom plate; the motor is fixed at the right end of the side plate through a screw; the right end of the screw rod is in interference fit with the motor; thepre-deformation bending clamping mechanism is slidably connected to the upper end of the rail. By the arrangement of the pre-deformation bending clamping mechanism, a lower deformation clamping structure cooperates with a clamping bending structure to perform multi-section stress fixing and deformation clamping on the tail end of a copper wire, so that the number of stress nodes of the copper wire is increased, and breakage or falling of the copper wire due to single stress and reduction of the diameter in a stretching process is prevented.

Description

technical field [0001] The invention relates to a copper wire indenter device for a stretching machine, in particular to a pre-deformed bending indenter device based on the physical characteristics of red copper wire. Background technique [0002] Copper wire has good electrical conductivity and is often used to make wires and cables. It has good plasticity and can be processed into copper parts of various shapes and sizes. Copper is widely used. To produce copper wire into copper wire requires a stretching machine. The two ends of the copper wire are fixed, and the copper wire is stretched to make it slender, and some problems will be encountered in the production of copper wire; because the strength and hardness of copper are lower than other types of copper, and the traditional drawing The fixing of the copper wire head by the stretching machine is only a simple single-section locking. During the stretching process, the diameter of the copper wire gradually becomes smalle...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a pre-deformed bending indenter device based on the physical properties of copper wire to solve the problem that the strength and hardness of copper are lower than other types of copper, and the traditional drawing machine The fixing of the copper wire head is only a simple single-section locking. During the stretching process, the diameter of the copper wire gradually becomes smaller, and the locked end of the copper wire is easily broken or directly separated from the locking part, resulting in failure of the stretching.
