A double hook stirrup automatic forming machine

Abstract

An automatic forming machine for double-hook hoops comprises a machine frame, a drive device arranged on the machine frame, a feeding device, a bending device, a material pushing device and a hook device, wherein the feeding device, the bending device, the material pushing device and the hook device are arranged on the machine frame and driven by the drive device. A receiving box is arranged below the hook device on the machine frame, the tail end of the feeding device is in butt joint with a station groove of the bending device, a long-strip-shaped steel bar which is conveyed into the station groove from the feeding device is punched downwards by the bending device to form a U-shaped structure, the steel bar of the U-shaped structure is then pushed by the material pushing device into a station groove of the hook device from the station groove of the bending device, and after the two ends of the steel bar of the U-shaped structure are bent to form hooked structures through the hook device, the steel bar automatically falls into the receiving box, so that automatic double-hook hooping work for the steel bar is completed. According to the automatic forming machine for the double-hook hoops, punching shearing force can be used for completing multiple machining processes from the long-strip-shaped steel bar to the final hook product at a time, the processes are simple, the automation degree is high, and the hook effect is good. Production efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of construction engineering machinery and equipment, in particular to an automatic stirrup forming machine that can continuously and automatically bend elongated steel bars into U-shaped steel bars with double-hook structures at both ends. Background technique

[0002] With the extensive use of concrete in the construction field, in order to meet the shear strength of oblique sections, various steel bending structures are required in concrete structures. Generally speaking, stirrups are divided into single-leg stirrups, open rectangular stirrups, and closed rectangular stirrups. , rhombus stirrups, polygonal stirrups, well-shaped stirrups and circular stirrups, etc. In addition, in order to strengthen the bonding force between the steel bar and the concrete, the end of the stressed bar should be provided with a hook when it is a smooth round bar. With the development of technology, the bending process has b...
