Wire drawing device for detecting tensile performance of electric heating wire

Abstract

The invention discloses a wire drawing device for testing the tensile performance of an electric heating wire, which comprises a support pipe, a recovery frame is arranged between the lower ends of the support pipe, a recovery groove is arranged inside the recovery frame, and the top of the recovery frame is an open structure; the support pipe A horizontal bar is provided between the upper ends of the pipe; a hydraulic cylinder is provided at the side of the supporting pipe, a piston rod is provided on the upper part of the hydraulic cylinder, a lifting plate is provided between the ends of the piston rod, and a lifting seat is provided at the front of the lifting plate , the lower part of the lifting plate is provided with a positioning plate, between the positioning plate and the lifting seat is a slot, and the side position of the lifting seat is provided with several positioning grooves. The lifting plate of the present invention can pull up or down the lower end of the heating wire through the positioning plate; it is convenient to pull the heating wire down slowly to break the heating wire, so that it is convenient for the operator to check the tensile performance of the heating wire. detection.

Description

technical field [0001] The invention relates to a wire drawing device, in particular to a wire drawing device for testing the tensile performance of an electric heating wire. Background technique [0002] Surface brushing treatment is a surface treatment method that forms lines on the surface of the workpiece by grinding products to achieve a decorative effect. Because the brushed surface treatment can reflect the texture of metal materials, it has been loved by more and more users and has become more and more widely used. After the adhesive is prepared, due to exceeding the active period, the glue is partially coagulated and becomes a filament under stretching. The atomization of the paint is not good during spraying, so that the paint cannot be turned into fine mist droplets and sprayed out in a filamentary shape, and the resulting coating film cannot be leveled, and wire drawing appears. The reason is that the coating has a high viscosity during construction and the d...

AI Technical Summary

Problems solved by technology

The two ends of the existing heating wire are inconvenient to fix, it is inconvenient to pull the heating wire, it is inconvenient to break the heating wire, and the operation efficiency of the tensile performance test of the heating wire is low
