Steel bar strapping machine

Abstract

The invention discloses a steel bar strapping machine which comprises a machine head, a casing, a transmission system, a wire feeding system fixed inside the casing, a wire cutting system and a stranding system. The stranding system comprises a stranding shaft, wherein the stranding shaft is of a segmented structure and comprises a driving shaft and a driven shaft at least. The stranding system further comprises a slipping device for being connected with the driving shaft and the driven shaft. When transfer torque between the driving shaft and the driven shaft exceeds slipping torque of the slipping device, the driving shaft breaks away from the driven shaft in a transmission mode. The stranding shaft of the steel bar strapping machine is designed to be of the structure provided with at least two segments, and the slipping device is added and enables the driving shaft and the driven shaft to be connected. When the transfer torque between the driving shaft and the driven shaft exceeds the preset slipping torque of the slipping device, the slipping device slips and accordingly enables the driven shaft to stop rotating and suspending stranding process, the torque control effect is achieved, iron wires are prevented from being twisted off, the labor amount of workers is reduced, the operation efficiency is improved, and the operation safety is ensured.

Description

technical field [0001] The invention relates to a binding machine, in particular to a steel bar binding machine. Background technique [0002] At present, iron wires and other wires are usually required to bind and position the steel frame on the construction site. Now this work is mainly done by manual operation. This manual operation has the following problems: low binding efficiency, inconvenient operation, non-standard binding, waste of binding use steel wire. Therefore, a steel wire binding machine has appeared on the market, which includes a machine head, a housing, a transmission system, and a wire feeding system, a wire cutting system, and a twisting system fixed inside the housing; the machine head is generally in the shape of a "C" A groove for positioning the steel frame is formed, and the iron wire passes through the deformation mechanism in the machine head (that is, the arc-shaped guide wire through hole) to bundle the steel frame in an arc-shaped surrounding ...

[0002] At present, iron wires and other wires are usually required to bind and position the steel frame on the construction site. Now this work is mainly done by manual operation. This manual operation has the following problems: low binding efficiency, inconvenient operation, non-standard binding, waste of binding use steel wire

During the twisting process, the torque increases continuously, so the iron wire is often broken due to excessive torque. Especially for manual steel bar binding machines, it is difficult for workers to control the appropriate torque. After the iron wire is twisted, it can only be tied again. It will lead to duplication of work, reduce work efficiency, and even cause safety accidents when the iron wire is in a half-twisted state.
