Pile tip bending machine for prefabricated pile reinforcing cages of different sizes

Abstract

The invention discloses a pile tip bending machine for prefabricated pile reinforcing cages of different sizes. The pile tip bending machine comprises a rack, wherein the rack comprises a base and vertical supporting plates which are arranged on the base, the vertical supporting plates comprise the first vertical supporting plate and the second vertical supporting plate which are arranged in a front-back mode and parallel with each other, a driving portion and a reinforcing steel bar guiding and positioning mechanism are installed between the first vertical supporting plate and the second vertical supporting plate, the reinforcing steel bar guiding and positioning mechanism comprises an adjustable blocking portion and a plurality of sets of reinforcing steel bar limiting portions which are matched with the adjustable blocking portion, the sizes of the reinforcing cages corresponding to the different sets of the reinforcing steel bar limiting portions are different, a pile tip limiting mechanism is arranged on the base, the base comprises two parallel transverse plates and two parallel sliding tracks which are arranged between the two transverse plates, and the vertical supporting plates can slide along the sliding tracks. By the aid of the pile tip bending machine, the reinforcing cages of the different sizes can be bent, and the pile tip bending machine is simple to operate and high in stability.

Description

technical field [0001] The invention relates to a steel bar bending machine, in particular to a pile tip bending machine used for reinforcing cages of prefabricated piles of different sizes. Background technique [0002] Prefabricated concrete piles can be divided into two categories: prefabricated reinforced concrete piles and prestressed concrete piles according to the type of main reinforcement and the corresponding production process. Among them, prefabricated reinforced concrete piles are formed by densely binding stirrups and hooping main reinforcements to pre-fabricate reinforcement cages, and after adjustment, inspection, and mold closing, concrete is poured, covered, and maintained. The traditional reinforcement cage can bend its tip before binding, and then bind the stirrups. However, the reinforcement cage of the existing prefabricated high-strength concrete square pile is formed by automatic rolling welding, and the pile tip can only be placed between the hoops. ...

AI Technical Summary

Problems solved by technology

The traditional reinforcement cage can bend its tip before binding, and then bind the stirrups. However, the reinforcement cage of the existing prefabricated high-strength concrete square pile is formed by automatic rolling welding, and the pile tip can only be placed between the hoops. The bending can only be carried out after the seam welding is completed. If manual bending is used, it is not only time-consuming and laborious, but also the bending size and bending angle are difficult to control, and it is easy to damage the steel cage that has been seamed.

[0003] In addition, the existing steel cage bending machine can only bend a square steel cage of a specific size. When the side length of the steel cage changes, the existing steel cage bending machine cannot make corresponding changes. That is, it is not possible to switch between reinforcement cages of different sizes, and the scope of application is small
