Certain specific fields require steel with high straightness, and it is difficult to meet these requirements for steel that has been bent or reused. Currently, straightening machines are commonly used for straightening steel, but existing straightening machines suffer from problems such as insufficient cylinder mobility, low cylinder shaft control precision, unreasonable oil tank design, and limited base mobility.

[0003] In view of the above-mentioned shortcomings of the prior art, this application proposes an improved hydraulic moving device. By optimizing the design of the cylinder, cylinder shaft, oil tank and base, the limitations of the prior art are solved, and the flexibility, adaptability and operating accuracy of the equipment are significantly improved.

[0035] like Figures 1-4 As shown, the movable steel bending and straightening device 1 of this application includes a base 10, a first oil tank 20, a second oil tank 30, an oil cylinder 40, an oil cylinder shaft 50, and a moving component 60.

[0036] Specifically, in this embodiment, the base 10 is used to support the steel to be straightened, and a moving component 60 is installed at the bottom of the base 10. The moving component 60 is used to drive the base 10 to move in a plane.

[0037] In this embodiment, the moving component 60 can be composed of multiple casters. Optionally, the moving component 60 in this embodiment includes four casters, which are located at the four top corners of the base 10. Through the multi-directional movement of the casters, the movable steel bending and straightening device 1 can be driven to move in a plane, thereby realizing the free movement and position adjustment of the movable steel bending and straightening device 1.

[0038] The base 10 in this embodiment can be composed of two independently installed steel pipes. Furthermore, the base 10 in this embodiment is also provided with a fixing structure 11 on the side opposite to the moving component 60. The fixing structure 11 is used to fix the first oil tank 20 and the second oil tank 30, and also to fix the base 10.

[0039] Optionally, the fixing structure 11 in this embodiment is composed of multiple steel pipes spliced ​​horizontally and vertically, and its specific shape can be H-shaped. The notch of the H-shape is used to set the first oil tank 20 and the second oil tank 30. The fixing structure 11 and the first oil tank 20 and the second oil tank 30 are mutually fixed by means of interlocking.

[0040] In this embodiment, the first oil tank 20 and the second oil tank 30 are installed on opposite sides of the base 10 along the first direction X, and the first oil tank 20 and the second oil tank 30 are interconnected through a connecting pipe 70. The connecting pipe 70 is located on the side of the first oil tank 20 and the second oil tank 30 near the fixing structure 11, and the horizontal tube of the fixing structure 11 is provided with a through hole, through which the connecting pipe 70 passes. The fixing structure 11 further realizes the fixed connection between the connecting pipe 70 and the first oil tank 20, and between the connecting pipe 70 and the second oil tank 30.

[0041] Optionally, the connecting pipe 70 in this embodiment may be further provided with a valve for controlling the flow of oil in the first oil tank 20 and the second oil tank 30. For example, the valve is a one-way valve, and by adjusting the valve's direction of flow, the flow direction of the oil is changed, thereby adjusting the movement direction of the hydraulic cylinder and / or the movement direction of the hydraulic cylinder shaft.

[0042] In this embodiment, the hydraulic cylinder 40 is installed on the side of the first oil tank 20 and the second oil tank 30 away from the base 10. The hydraulic cylinder 40 can move along the first direction X. The hydraulic cylinder shaft 50 is fixedly installed on the hydraulic cylinder 40 and can perform upward and downward movements along the second direction Y, which is perpendicular to the first direction X.

[0043] In this embodiment, the hydraulic cylinder 40 includes a hydraulic cylinder bracket 41 and a sliding component 42. The first end of the hydraulic cylinder bracket 41 is fixedly connected to the first oil tank 20, and the second end of the hydraulic cylinder bracket 41 is fixedly connected to the second oil tank 30. The hydraulic cylinder bracket 41 has a through groove 43. The sliding component 42 is disposed on the side of the hydraulic cylinder bracket 41 away from the base 10 and is slidably connected to the top wall of the hydraulic cylinder bracket 41.

[0044] Optionally, the cylinder bracket 41 in this embodiment is composed of two separate bracket plates, each bracket plate abutting against the outer side wall of the first oil tank 20 and the second oil tank 30, and a through groove 43 is formed between the two bracket plates and the two oil tanks.

[0045] Furthermore, the sliding assembly 42 of this embodiment includes at least two roller structures 421 and a guide rail structure 422. The guide rail structure 422 is fixed to the top wall of the cylinder bracket 41, and the roller structures 421 are disposed within the guide rail structure 422 and can roll along the guide rail structure 422. The cylinder shaft 50 of this embodiment is disposed within the through groove 43 and sandwiched between at least two roller structures 421.

[0046] The guide rail structure 422 includes a first guide rail structure and a second guide rail structure, which are respectively disposed on both sides of the through groove 43, specifically disposed on the top walls of the two support plates, or the top walls of the two support plates form guide rail grooves. The at least two roller structures 421 include two sets of roller structures 421, each set of roller structures 421 including two rollers respectively disposed on the first guide rail structure and the second guide rail structure, and the two rollers are connected by support rods. When the hydraulic cylinder shaft 50 is disposed in the through groove 43, it abuts against the two sets of support rods.

[0047] When the roller structure 421 moves along the first guide rail structure and the second guide rail structure, it drives the fixedly connected oil cylinder shaft 50 to move. The direction of movement is the extension direction of the guide rail structure 422. In this embodiment, the specific direction of movement is the first direction X.

[0048] Furthermore, in this embodiment, an extension shaft 51 is provided on the side of the cylinder shaft 50 near the base 10, wherein the diameter of the extension shaft 51 is smaller than the diameter of the cylinder shaft 50, and the end face of the extension shaft 51 facing away from the cylinder shaft 50 is flat. When the cylinder shaft 50 performs a rising or falling motion, it drives the extension shaft 51 to perform a rising or falling motion. When performing a falling motion, the end face of the extension shaft 51 abuts against the steel placed on the base 10 to bend and straighten the uneven steel. After bending and straightening is completed, the cylinder shaft 50 then rises to facilitate the removal of the flat steel.

[0049] Optionally, in this embodiment, a fixing plate is provided on the side of the cylinder shaft 50 near the base 10. The hydraulic control system of this embodiment is provided on the cylinder shaft 50, specifically on the fixing plate, and is fixedly connected to the extension shaft 51.

[0050] The hydraulic control system of this embodiment connects the first oil tank 20 and the second oil tank 30, and is used to control the oil cylinder 40 to move left and right along the first direction X, or to control the oil cylinder shaft 50 to move up and down along the second direction Y.

[0051] This application improves the flexibility and applicability of the movable steel bending and straightening device 1 by installing a moving component 60 at the bottom of the base 10, which drives the movable steel bending and straightening device 1 to move in a plane. The first oil tank 20 and the second oil tank 30, which are arranged opposite each other and connected by a connecting pipe 70, can effectively improve the uniformity of oil distribution and improve the stability and efficiency of hydraulic control system. The cylinder shaft 50 is installed on the cylinder 40, and the moving component 42 in the cylinder 40 can drive the cylinder shaft 50 to move left and right along the first direction X, and the cylinder shaft 50 can move upward and downward along the second direction Y, which can improve the operating accuracy and flexibility of the movable steel bending and straightening device 1.
