Abstract

The invention discloses a steel bar bending machining method. The steel bar bending machining method comprises the following steps that derusting is conducted, a steel bar to be machined is selected,and is subjected to manual derusting with a steel brush; measuring and calculating are conducted, the dimension required by bending of the whole steel bar is calculated based on the bending angle of the steel bar, the required length of the steel bar is measured, and the steel bar is cut with a cutting machine; and mold installation is conducted, a bending mold is mounted at a hydraulic pipe bending machine, the hydraulic pipe bending machine is turned on, and hydraulic operation is started. The method solves the problem in the prior art that steel bar is wasted, and therefore application reasonableness is lowered, yield of steel bar leftover materials is increased, the production cost of a factory is increased, and application and development of the factory is not facilitated. The steel bar bending machining method has the advantage of saving materials. Steels bars can be used maximumlly and rationally. The cutting times of the steels bar are reduced. Operation of workers is facilitated. The method is worth popularization and application.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a steel bar bending processing method. Background technique [0002] As the skeleton of concrete, steel bars constitute reinforced concrete, and become the main material used widely and in large quantities in building structures. Before pouring concrete, steel bars must be made into a skeleton of a certain size and form and incorporated into the formwork. To make a steel bar skeleton, it is necessary to carry out Reinforcing, stretching, straightening, cutting, bending, connecting and other processing can be finally bundled into shape. Due to the huge amount of steel used, manual operations are difficult to complete, and various special machines are required for processing. This type of machine is called steel bar processing machinery. Referred to as steel machinery. [0003] Under the pressure of the upper or lower die of the bending machine, the bent metal sheet fi...
