A double-hook stirrup machine-used hook device

Abstract

A hook device for a double-hook hooping machine comprises a frame and a station groove formed in the frame. The station groove is used for fixedly clamping to-be-hooked U-shaped rebars, a pull rod driven by a driving device is arranged on one side of the station groove, one end, close to the station groove, of the pull rod is connected onto a slide seat, slide rods are fixed to two ends of the slide seat, and a stamping rod used for stamping the U-shaped rebars is connected between tail ends, extending to the other side of the station groove, of the two slide rods. A straightening device used for buffering stamping force applied to middles of the U-shaped rebars is arranged on one side, facing the pull rod, of the station groove. A slide rail is horizontally arranged on the frame, the pull rod can be driven by the driving device to further drive the slide rods to slide back and forth on the slide rail through the slide seat, and then the stamping rod is driven to stamp on one side, with the pull rod, of the station groove to complete hooking operations of two ends of the U-shaped rebars in the station groove. By arrangement of the stamping rod and the straightening device, hooking operations of two ends of the U-shaped rebars can be completed by one time, and procedure simplicity and effectiveness in hooking are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering machinery and equipment, in particular to a hook device for a double-hook stirrup machine that can bend both ends of a U-shaped steel bar into a hook-shaped structure. 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, when the stressed bar is a smooth round steel bar, a hook should be provided at the end. With the development of technology, the hook process has been widely used in the stirrup machine for proces...

Problems solved by technology

In addition, in order to strengthen the bonding force between the steel bar and the concrete, when the stressed bar is a smooth round steel bar, a hook should be provided at the end. With the development of technology, the hook process has been widely used in the stirrup machine for processing, but most stirrup machines After the straight steel bar is bent into a U-shape, the hooks at both ends of the U-shape work due to the small stress area and the excessive stamping force on the unhooked parts. When the two ends are bent, the middle part is easily twisted and deformed, resulting in The working process of the hook is complicated

Therefore, in some production lines, the work of the hooks at both ends of the U-shaped steel bar is changed to manual beating work or manual straightening in the middle of the steel bar. These methods are not only time-consuming, labor-intensive, time-consuming, and have great potential safety hazards, but also increase costs.
