Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools for building construction, and more specifically, relates to a handheld steel bar straightening and cutting system based on hydraulic control. Background Art

[0002] At present, in the engineering field, cast-in-place piles are a common form of foundation, which is formed by pouring concrete into pre-drilled holes. As the foundation of a building (structure), the pile body steel bars need to enter the upper structure. In order to ensure the strength of the pile head concrete, when pouring the cast-in-place pile, the cast-in-place pile top elevation should be 0.5 to 1.0 m higher than the designed pile top elevation. After the pile body concrete reaches a certain strength, the pile head that is higher than the designed pile top elevation will be chiseled off. However, after the cast-in-place pile breaks the pile head concrete, it is inevitable that the part of the steel bars above the designed pile top elevation will be irregularly bent, which needs to be straightened. The processing and forming of steel bars directly affect the strength and engineering quality of reinforced concrete structures. At present, the more commonly used steel bar straightening methods are: 1. Homemade steel pipe wrench straightening method and oxygen and acetylene baking straightening method. Among them, although the homemade steel pipe wrench straightening method has a low cost, the operation is cumbersome and is not effective for steel bars with multiple bends; the oxygen and acetylene baking straightening method can locally heat the steel bars to soften them and facilitate bending, but this method may affect the mechanical properties of the steel bars; it can be seen that when a single steel bar at the pile head has multiple bends, the homemade steel pipe wrench cannot effectively handle steel bars with multiple bends or complex shapes, resulting in a certain degree of bending in the straightened steel bars; and the use of oxygen and acetylene baking straightening method may have a negative impact on the mechanical properties of the steel bars, such as reducing their tensile strength or durability; when using high-temperature heat sources such as oxygen and acetylene for straightening, there are certain safety risks, such as fire and explosion; there is no special tool for straightening in the prior art, but manpower is used for straightening, which is not only inefficient, labor-intensive and costly, but also has limitations in manual straightening and cannot be precisely controlled. In addition, after the steel bars are straightened, they usually need to be cut according to the required length. When the traditional steel bar straightening and cutting machine is working, the straightening mechanism straightens the steel bars and then controls the blade to cut the steel bars through a mechanical clutch. The clutch needs to be mechanically opened or disconnected during cutting, which has a complex structure and is time-consuming to operate. Summary of the invention

[0003] In view of the above defects or improvement needs of the prior art, the utility model provides a handheld steel bar straightening and cutting system based on hydraulic control, which adopts the principle of hydraulic straightening and cutting, controls the resistance column to be fixed to the steel bar that needs to be cut and straightened, operates the straightening control button to control the straightening hydraulic cylinder to drag the wrench to move to achieve the straightening function, and operates the cutting control button to control the cutting hydraulic cylinder to control the cutting head to move to achieve the cutting function. The overall structure is compact, easy to carry, small working surface, easy to disassemble, convenient construction, safe and easy to operate, saving construction time, reducing the labor intensity of workers, and can adjust the accuracy within the straightening range; it can realize the integration of straightening and cutting of multiple sections of curved or complex-shaped steel bars, improve the efficiency and safety of steel bar processing, and can solve the problems of twisting and deformation of exposed steel bars at the traditional pile head, large errors, and complex assembly and disassembly processes.

[0008] The control assembly includes a control handle arranged on the side of the handheld part, a straightening control button connected to the straightening hydraulic cylinder and a cutting control button connected to the cutting hydraulic cylinder arranged on the control handle, and a controller connected to the straightening control button and the cutting control button respectively.
