Problems solved by technology

[0003] At present, continuous fiber-reinforced thermosetting resin composite materials are generally used in the FRP bars used for reinforcement or reinforcement in civil engineering, but thermosetting FRP bars do not have the characteristics of secondary molding, and most of them are prefabricated components, which cannot be re-formed at the construction site. Processing, and the tendons (such as stirrups) in actual engineering usually need to bend the FRP tendons at 45 degrees or 90 degrees
In addition, studies and experiments have shown that the tensile strength of thermosetting FRP bars will be significantly reduced at the bend

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] combine Figure 1 to Figure 9 , a thermoplastic FRP tendon bending device of the present invention includes a fixing mechanism 1 , a rotating mechanism 2 , a slider 4 , a heater 9 and a cooler 10 . A clockwork spring 3 is arranged between the fixed mechanism 1 and the rotating mechanism 2, the guide rail 5 passes through the fixed mechanism 1 and the slider 4, the two ends of the guide rail 5 are fixed on the working platform 13 with the base 12, and the stepping motor 7 passes through the screw rod 6. Drive and control the slider 4. Under the action of the slider 4, the rotating mechanism 2 and the fixing mechanism 1 can undergo translation and rotation. Through the translation, the FRP bars move between the heater 9 and the cooler 10, and through the rotation, the FRP The tendon bends.

[0023] The fixing mechanism 1 moves ...

Abstract

The invention provides a thermoplastic FRP rib bending device. The device comprises a fixing mechanism, a rotating mechanism, a slide block, a heater and a cooler. A spring is arranged between the fixing mechanism and the rotating mechanism; a guide rail penetrates through the fixing mechanism and the slide block; two ends of the guide rail are fixed on a working platform by a base; a stepper motor drives and controls the slide block through a lead screw; under the effect of the slide block, the rotating mechanism and the fixing mechanism can perform translation and rotation; through translation, FRP ribs move between the heater and the cooler; through rotation, the FRP ribs are bent; and the bending angles are 0-90 degrees. The device has such advantages as high automation degree, high machining precision, simple operation and low requirements on constructors and places.

Description

technical field [0001] The invention relates to a fiber composite material processing equipment, in particular to a thermoplastic FRP tendon bending device. Background technique [0002] Fiber Reinforced Polymer (FRP for short) is a high-performance material formed by combining continuous fiber materials with matrix resin, and FRP bars are one of its product forms. Using FRP bars instead of steel bars in concrete structures can give full play to its advantages of light weight, high strength, corrosion resistance, fatigue resistance, and non-magnetism, especially in harsh environments such as acid, alkali salt, and humidity, which can avoid the impact of steel bar corrosion on the structure. damage, reduce structural maintenance costs, and prolong the service life of the structure. [0003] At present, continuous fiber-reinforced thermosetting resin composite materials are generally used in the FRP bars used for reinforcement or reinforcement in civil engineering, but thermo...
