A pre-deformed bending indenter device based on the physical properties of copper wire

Abstract

The invention discloses a pre-deformation bending pressure head device based on the physical characteristics of red copper wire. Wire drum and reel locking frame, the support plate is welded on the right end of the lower surface of the bottom plate, the track is embedded in the middle section of the upper surface of the bottom plate, the side plate is welded on the right end of the upper surface of the bottom plate, the motor is fixed on the right end of the side plate by screws, the screw rod The right end is in interference fit with the motor, and the pre-deformation and bending clamping mechanism is slidably connected to the upper end of the track. The present invention provides a pre-deformation and bending clamping mechanism, and the lower deformation clamping structure cooperates with the clamping and bending structure, and the copper The end of the wire is fixed by multi-section force and clamped by deformation to increase the stress nodes of the copper wire and prevent the copper wire from breaking or falling off due to single force and small diameter during the stretching process.

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.
