Description

Technical Field

[0001] The utility model relates to the technical field of building material production, in particular to a bending device for building material production. Background Art

[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into inorganic materials, organic materials and composite materials. Inorganic materials include metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metallic materials (such as natural stone, burnt earth products, cement, concrete and silicate products, etc.); organic materials include plant materials, synthetic polymer materials (including plastics, coatings, adhesives) and asphalt materials; composite materials include asphalt concrete, polymer concrete, etc., which are generally composed of inorganic non-metallic materials and organic materials. More steel bars are needed in construction projects, and the steel bars need to be bent during the production process.

[0003] When bending steel bars, usually a single steel bar is placed into a bending device manually and then bent manually. Manual bending requires a lot of effort and has low efficiency. Operators may also rub their hands during the bending process. Moreover, the bending device can only bend steel bars of a single specification and has low applicability.

[0004] Therefore, we make improvements to this and propose a bending device for producing building materials. Utility Model Content
