Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail net processing, and more specifically, relates to a bending device for a guardrail net. Background Art

[0002] Guardrail net is also known as isolation fence. Guardrail net is mainly used for guardrail protection of roads, railways, airports, residential areas, ports and docks, gardens, breeding, livestock, etc. Its characteristics are anti-corrosion, anti-aging, anti-sun and weather resistance. The surface anti-corrosion forms of guardrail net include electroplating, hot-dip galvanizing, plastic spraying and plastic dipping.

[0003] In order to prevent climbing, the top of the existing guardrail net is bent at a certain angle. However, the existing bending method is to manually bend the guardrail net cut into uniform specifications. This manual bending method not only cannot control the bending angle, but also has low bending efficiency. In the subsequent welding with the mounting rod, the bending angle at the bending point of the mounting rod deviates, and the overall aesthetics of the weld is poor.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a bending device for a guardrail net is provided in order to achieve a purpose with greater practical value. Utility Model Content
