Novel U-shaped screw bender

Abstract

The invention relates to a novel U-shaped screw bender which comprises an operation platform, a bending disc die, a rotating shaft, a positioning buckle, a motor, supporting legs and a limiting device. The supporting legs are arranged at four corners below the operation platform. The motor is arranged to drive the bending disc die to rotate to realize production of U-shaped screws, so that manpower is thoroughly liberated, working intensity of operating personnel is greatly lowered, and working efficiency is high; the machine is simple and convenient to operate, time-saving and labor-saving, and needed U-shaped screws can be obtained by only sequentially inserting raw materials into a limiting hole formed by an upper limiting groove and a lower limiting groove and a positioning hole formedby a circumferential groove and a first positioning groove, extending out a section from the positioning hole, driving the first positioning groove in the positioning buckle through a positioning bolt to tightly press the raw materials into the circumferential groove of the bending disc die, enabling the rear ends of the raw material to be positioned in the limiting groove and enabling the motorto drive the bending disc die on the rotating shaft to rotate by 180 degrees.

Description

Technical field [0001] The invention belongs to the technical field of screw processing, and particularly relates to a novel U-shaped screw bending machine. Background technique [0002] At present, in many constructions or structural connection installations, a large number of U-shaped screws need to be used. Generally, the production and processing of U-shaped screws is mainly through the use of straight raw materials (for example, stainless steel wire, etc.) by related operators. Gas welding and other equipment are roasted for bending. This production method has extremely low bending efficiency and cannot guarantee the personal safety of the operator. At the same time, the quality of the finished product is relatively uneven; in addition, it cannot meet the requirements of different models. Bending requirements have brought great inconvenience to users. Although the existing U-shaped steel wire bending machine does not need to be baked for bending, most of them use the princip...

Problems solved by technology

[0002] At present, in many construction or structural connection installations, a large number of U-shaped screws need to be used. Generally, the bending production and processing of U-shaped screws is mainly through the use of straight raw materials (such as stainless steel wire, etc.) by relevant operators. Gas welding and other equipment are used to bake and bend. This production method has extremely low bending efficiency and cannot guarantee the personal safety of operators. At the same time, the quality of the finished products is not uniform; Bending requirements have brought great inconvenience to users. Although the existing U-shaped steel wire bending machines do not need to be baked for bending, most of them use the principle of leverage to cooperate with the bending disc mold to produce U-shaped screws. However, manual operation is still required, especially after the bending is completed, the curing time requires artificially holding the handle or the position of the handle for a long time, which does not reduce the working intensity of the operator very well.
