Portable adjustable handheld steel bar bending machine based on TRIZ

Abstract

The invention discloses a portable adjustable handheld steel bar bending machine based on TRIZ. The portable adjustable handheld steel bar bending machine based on TRIZ is composed of a bending machine main body, a piston rod and concave wheels; the bending machine main body is composed of a machine body and a steel frame; the piston rod is composed of a rod body and a hook handle; and the concavewheels are composed of wheel columns. The portable adjustable handheld steel bar bending machine has the beneficial effects that a hydraulic cylinder and the rod body are matched with each other, andthus, steel bars can be pulled to be bent; the multiple sets of concave wheels are installed in wheel holes so that thick and fine steel bars with any angles and any bending degrees can be bent; a rear handle and a front handle can fix the machine when the bending machine is used; external threads on the concave wheels and internal threads on the wheel holes can be tightly engaged so that the concave wheels can be prevented from being disengaged; and the steel bars can be pulled to the greatest extent and prevented from sliding off through a C-shaped hook groove formed in the hook handle.

Description

technical field [0001] The invention relates to a portable and adjustable hand-held steel bar bending machine based on TRIZ. Specifically, multiple sets of concave wheels of the same type are used to cooperate with each other to pull steel bars of different specifications, and belong to the field of construction machinery. Background technique [0002] Nowadays, steel bar bending machine is one of the indispensable tools and equipment in steel bar processing. It is widely used in construction occasions. It is mainly used for bending and cutting steel bars. Considering the immovability and difficulty of moving of fixed steel bar bending machines Therefore, the portable steel bending machine was born. However, the existing portable steel bar bending machine has the problem that the distance between the two concave wheels cannot be adjusted flexibly, which poses a new challenge to the steel bar bending task under multi-standard and complicated conditions. [0003] The patent n...

However, the existing portable steel bar bending machine has the problem of not being able to flexibly adjust the distance between the two concave wheels, which poses a new challenge to the steel bar bending task under multi-specification and complex conditions

[0003] The patent number is CN201620260037, and the patent name is "A Portable Simple Steel Bar Bending Tool". A steel bar bending tool is disclosed. Three axes are set to bend steel bars of different degrees. However, the bending degree of this method is limited, only the arc Different, can not according to the actual needs, such as asymmetric curved steel bars and steel bars with different outer fillets, and obtain the required curved steel bars. In addition, the machine needs to rely on manpower to complete the bending of steel bars, which is inefficient and labor-intensive. , and the operation process is not easy to control
