Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: both the horizontal straightening mechanism and the vertical straightening mechanism perform straightening processing through the cooperating pressure rollers. The spacing is the width that matches the diameter of the steel bar itself. For the coiled steel bar, under the action of its own stress, it will generally form a spiral shape after unfolding. If it does not go through the early traction and pretreatment, it will directly enter the horizontal straightening mechanism, vertical Straightening mechanism, greatly reducing the straightening effect

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , is a steel bar straightening and bending machine disclosed in this embodiment, the first presetting mechanism 1, the second presetting mechanism 2, the horizontal straightening mechanism 3, the feeding mechanism 4, the vertical Straightening mechanism 5, cutting mechanism 6, bending mechanism 7 and transmission mechanism 8. The steel bar is transmitted through the feeding mechanism 4, and first enters the first presetting mechanism 1 and the second presetting mechanism 2 for presetting processing, so that the spiral steel bar can be extended into the horizontal straightening mechanism 3 and the vertical straightening mechanism 5. Perform straightening processing, through the mutual cooperation of the transmission mechanism 8 and the bending mechanism 7, so as to perform bending processing on the steel bars and realize the blanking ...

Abstract

The invention relates to the technical field of steel bar bending equipment, in particular to a steel bar straightening and bending machine. The machine comprises a first pre-shaping mechanism, a horizontal straightening mechanism, a feeding mechanism, a vertical straightening mechanism, a cutting mechanism, a bending mechanism and a conveying mechanism which are arranged in the conveying direction of steel bars sequentially, wherein the first pre-shaping mechanism comprises a first support frame, a first pre-shaping assembly arranged on the first support frame and used for limiting the bending degree of the steel bars and a second pre-shaping assembly arranged on the first pre-shaping assembly and used for limiting the diameter of a channel defined by the first adjusting assembly; and thefirst adjusting assembly is connected to the first support frame by a first sliding assembly. The machine has better straightening effect.

Description

technical field [0001] The invention relates to the technical field of steel bar bending equipment, in particular to a steel bar straightening and bending machine. Background technique [0002] Reinforced concrete civil air defense doors are commonly used products in civil air defense projects, and are usually installed in civil air defense basement passages. Reinforced concrete civil air defense doors are composed of reinforced concrete and door leaf edge steel, hinges, locks and other steel structural parts, and the most important component is steel bars. [0003] The raw materials of steel bars are packaged in rolls. During preparation, the rolled steel bars need to be straightened and then bent to the required shape before cutting. [0004] The Chinese patent with the notification number CN106040909B discloses a steel bar automatic hoop bending machine, including a horizontal straightening mechanism, a feeding mechanism, a vertical straightening mechanism, a traction me...
