Handheld coiled round wire material head straightening machine

Abstract

Disclosed is a handheld coiled round wire material head straightening machine. The handheld coiled round wire material head straightening machine comprises a machine frame and a pneumatic-hydraulic pressurizer. The pneumatic-hydraulic pressurizer comprises a pressurizing oil cylinder, a pressurizing air cylinder and an oil storage barrel. A front handle and a rear handle are arranged at the two ends of the pressurizing oil cylinder respectively, and a button type mechanical valve is arranged on the rear handle. The pressurizing oil cylinder of the pneumatic-hydraulic pressurizer is connected with the machine frame, a piston rod in the pressurizing oil cylinder is connected with a movable head, and two supporting heads are fixed to the machine frame. Each supporting head comprises a supporting shaft and a straightening roller, wherein the supporting shaft is fixed to the machine frame, the straightening roller is installed on the supporting shaft in a sleeving mode, and a locating groove is formed in the straightening roller. A locating groove is formed in the movable head. In the straightening process, the two ends of a material head are located through the supporting heads, and the movable head pushes and presses the middle section of the material head to achieve the curve straightening purpose. The handheld coiled round wire material head straightening machine is small in integral size, simple in structure, light in weight and low in manufacturing cost, convenient and flexible to carry with hands and easy to maintain, and applicable to on-site straightening operation.

Description

technical field [0001] The invention relates to a straightening machine, in particular to a hand-held coiled wire material head straightening machine. Background technique [0002] In the fastener industry, most of the large-scale cold forming equipment adopts coiled wire rods. The front end of the equipment host is equipped with coiled material uncoiling horizontal material racks to facilitate automatic uncoiling and straightening of materials. The uncoiling horizontal material racks are composed of upper and lower sets of pressing wheels and Composed of multiple sets of straightening wheels, the pressing wheel plays the role of uncoiling, and the coiled wire is opened, and the strong friction generated by its rotation pulls the wire to the straightening wheel, and the straightening wheel plays the role of straightening, which can separate the raw materials one by one After straightening, it is sent to the main machine. There is a certain distance (usually 300-400mm) betwee...

AI Technical Summary

Problems solved by technology

For materials with a diameter less than 20mm, it is easy to straighten the material head with a sleeve; for materials with a larger diameter, such as between 25 and 32mm, one method is to straighten manually, but the efficiency is low and the labor intensity is high. Sometimes it needs to be straightened. Two people can pull it
