Clamping and returning bending mechanism on automatic hoop bending machine for steel bars

Abstract

The invention discloses a clamping and returning bending mechanism on an automatic hoop bending machine for steel bars. The clamping and returning bending mechanism is positioned on one side of a bending mechanism on the automatic hoop bending machine for the steel bars, and comprises a guide rail and a clamping base plate, wherein the bottom of the guide rail is fixed on a frame; one side surface of the clamping base plate is arranged on the upper part of the guide rail in a sliding fit mode; a steel bar clamping mechanism is arranged on the other side surface of the clamping base plate; and the clamping base plate is connected with a reciprocation driving unit driving the clamping base plate to move. The invention has the advantages that: the other end of a steel bar sheared by a shearing mechanism is bent, namely products that two ends of the steel bar have the same shape can be rapidly bent at one time simultaneously, and the production requirement is met; the bending mechanism is simple in structure, low in cost and high in adaptability and can be matched with the automatic hoop bending machine for the steel bars and other equipment with a bending mechanism; the function of the hoop bending machine is expanded, so that a lot of hooping products can be machined by the clamping and returning bending mechanism; and the bending mechanism can bend coiled steel bars and also can rapidly bend straight steel bar-molded hooping products general for engineering.

Description

technical field [0001] The invention relates to an automatic hoop bending machine for steel bars, in particular to a clamping and returning bending mechanism on the automatic hoop bending machine for steel bars. Background technique [0002] With the rapid development of economic construction, the automatic processing equipment for stirrups - the automatic bending machine for steel bars has been widely used. The prior art steel bar automatic hoop bending machine comprises: a traction mechanism, a straightening mechanism, a bending mechanism and a shearing mechanism. [0003] The production process of the above-mentioned prior art steel bar automatic hoop bending machine is: after the steel bar passes through the traction mechanism, the straightening mechanism, and the bending mechanism, the steel bar is processed and bent into a stirrup of a certain shape, and then cut off by the shearing mechanism. [0004] The above-mentioned prior art steel bar automatic bending hoop mac...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art steel bar automatic hoop bending machine has the following defects: the prior art steel bar automatic hoop bending machine can only bend the steel bar input to the bending mechanism, that is, it can bend different parts of a steel bar, or bend the steel bar into various parts. Various shapes, such as triangle, square, circle, etc., but the other end of the steel bar cut by the shearing mechanism cannot be bent, that is, the long stirrup products with hooks at both ends cannot be quickly bent

Some products cannot be automatically completed on the equipment at one time, and cannot fully meet the needs of production
