Description

Technical Field

[0001] The utility model belongs to the technical field of bending equipment for construction engineering, and specifically relates to a bending device for construction engineering. Background Art

[0002] At present, industrial manufacturing has higher and higher requirements for products, and product diversity is crucial. Thin steel plates are indispensable in industrial production. Due to the needs of industrial production, thin steel needs to be bent, which has a wider range of uses; especially in construction projects, thin steel plates often need to be temporarily bent. In construction projects, workers usually use simple tooling such as bending iron bars to bend thin steel plates temporarily. Due to the different thickness of thin steel plates, workers need to spend a lot of effort to complete it, and it is time-consuming and labor-intensive, and the bending accuracy is low.

[0003] At present, hydraulic bending machines have been widely used in construction projects to bend thin steel plates, and press the thin plates into parts of various shapes according to process requirements. General hydraulic bending machines can easily bend thin steel plates into right angles, but in the actual processing process, it is sometimes necessary to bend thin steel plates continuously to bend the plates in multiple sections or bend them into rings. However, general hydraulic bending machines cannot achieve continuous bending, and additional auxiliary tooling is required to be used with the hydraulic bending machine, which brings inconvenience to continuous bending. In addition, even if continuous bending is performed by using auxiliary tooling combined with a hydraulic bending machine, the curvature of the bending is not adjustable and the accuracy is poor, which makes it difficult to meet product requirements.

[0004] Therefore, how to design a bending device for construction engineering that is easy to operate, easy to adjust the bending curvature, has high bending accuracy and can perform continuous bending operations is a problem that needs to be solved urgently by technical personnel in this field.

[0040] Example 1

[0041] like Figure 1As shown, this embodiment provides a bending device for construction engineering, including a base 10, a hinge 20, a first bending assembly 30, a second bending assembly 40, and a first hydraulic pump 50, wherein the first bending assembly 30 and the second bending assembly 40 are rotatably connected through the hinge 20. Among them, the first hydraulic pump 50 is rotatably arranged on the base 10, and the output end of the first hydraulic pump 50 is rotatably connected to the first bending assembly 30, and the second bending assembly 40 is fixedly installed on the base 10 through an I-shaped pad. Specifically, by the expansion and contraction of the first hydraulic pump 50, the first bending assembly 30 is rotated relative to the second bending assembly 40, so that the change of the angle between the first bending assembly 30 and the second bending assembly 40 can be controlled, and the bending process of the thin steel plate placed on the first bending assembly 30 and the second bending assembly 40 can be realized. It should be noted that in other embodiments, universal wheels can be arranged on the base 10, so that the bending device for construction engineering can be conveniently moved.

[0042] like Figure 2 As shown, the first bending assembly 30 and the second bending assembly 40 both include a bending plate 31, a bending roller 33 and two bearing seats 32. The bending plate 31 of the first bending assembly 30 is connected to the output end of the first hydraulic pump 50 via a rotating member, the two bearing seats 32 are arranged along the axis parallel to the hinge 20, and the bending roller 33 passes through the two bearing seats 32 and is pinned to the inner ring of the corresponding bearing seat 32. Specifically, a thin steel plate is placed on the two parallel bending rollers 33, and the angle between the two bending plates 31 changes with the expansion and contraction of the first hydraulic pump 50, thereby realizing the arc bending of the thin steel plate. Furthermore, because the bending roller 33 can rotate relative to the bending plate 31 on which it is installed, the pushed thin steel plate moves on the rotating bending roller 33, achieving the effect of continuous bending of the thin steel plate. Preferably, the bending roller 33 located between the two bearing seats 32 is wrapped with an anti-slip sleeve. The anti-slip effect of the anti-slip sleeve can effectively prevent the thin steel plate from slipping on the bending roller 33, so as to avoid affecting the bending efficiency and accuracy of the thin steel plate.

[0043] like Figure 3 As shown, the hinge 20 has three hinges 21, and the hinge 21 is V-shaped. Figure 2 As shown, the bending plate 31 of the first bending assembly 30 can be selectively installed on any page of the V-shaped hinge, and the angle between the two bending plates 31 in the initial state can be set to achieve arc bending degrees of different radians, thereby broadening the arc bending product series.

[0044] like Figure 1 and Figure 2As shown, two rows of a plurality of first through holes 311 are symmetrically provided on the two bending plates 31 along the axial direction perpendicular to the hinge 20, and the two bearing seats 32 are provided on the bending plates 31 through the first through holes 311. Specifically, through the provision of the first through holes 311, the two bearing seats 32 can be installed on the area of ​​the bending plate 31 far away from the hinge 20, that is, the two bending rollers 33 are far apart, and when the two bending rollers 33 are far apart, the bending degree of the bent thin steel plate is also smaller; similarly, the two bearing seats 32 can also be installed on the area of ​​the bending plate 31 close to the hinge 20, that is, the two bending rollers 33 are close apart, and when the two bending rollers 33 are close apart, the bending degree of the bent thin steel plate is also greater. Of course, it should be noted that, according to the thickness of the thin steel plate to be processed, in order to facilitate smooth bending, the distance between the two bending rollers 33 needs to be adjusted according to the processing conditions.

[0045] like Figure 4 As shown, the bending device for construction engineering further includes a rotating table 11, and the rotating table 11 is installed on the base via a rotating member. A first protrusion 111 and a second protrusion 112 are provided on opposite sides of the rotating table 11, and a screw 113 is penetrated and screwed on the first protrusion 111. Specifically, the first hydraulic pump 50 is placed on the rotating table 11 and arranged close to the second protrusion 112, and the screw 113 is rotated so that the screw 113 moves toward the first hydraulic pump 50 until it is close to the first hydraulic pump 50, thereby fixing the first hydraulic pump 50 on the rotating table 11. In other words, this arrangement can realize the rapid installation and disassembly of the first hydraulic pump 50.

[0046] In summary, the working principle of the bending device for construction engineering is as follows: according to the bending requirements of the specific processed products, the bending plate in the first bending assembly is selectively installed on the hinge of the appropriate hinge; and then the spacing between the two bending rollers is selectively installed according to the bending curvature requirements of the thin steel plate to be processed. The thin steel plate to be processed is placed on the two bending rollers, and the output end is driven to extend and retract by the first hydraulic pump, which drives the bending plate in the first bending assembly to rotate so that the angle between the two bending plates changes to meet the processing requirements, and the thin steel plate can be continuously bent under the push, thereby realizing arc-shaped bending parts with different degrees of bending on a thin steel plate. The bending device for construction engineering of this embodiment has the characteristics of simple overall structure, high convenience of bending operation, adjustable bending curvature, high bending precision, etc., and can be generally applied to bending needs in construction engineering.

[0047] Example 2

[0048] like Figure 5As shown, the difference between this embodiment and the first embodiment is that: the base 10 is provided with support plates 12 on opposite sides, and the two support plates 12 are rotatably provided with blocking rollers 13, and the blocking rollers 13 are suspended above the hinge. The setting of the blocking rollers 13 can effectively prevent the thin steel plate from popping out during the bending process, thereby improving the bending efficiency and the safety of the bending.

[0049] Furthermore, the support plate 12 is provided with a plurality of second through holes 121 opened along the height direction thereof. Through the provision of the plurality of second through holes 121, the height between the blocking roller 13 and the hinge can be adjusted, so that the bending device for construction engineering is suitable for the thickness bending of thin steel plates, and is used to coordinate the requirements of different bending degrees in the bending of thin steel plates.

[0050] Example 3

[0051] like Figure 6 As shown, the difference between this embodiment and embodiment 3 is that: the number of hydraulic pumps is two, and a second hydraulic pump 60 is also provided. The output end of the second hydraulic pump 60 is installed on the bending plate of the second bending assembly 40, and the second hydraulic pump 60 is rotatably installed on the base 10. Specifically, the two bending plates 31 can adjust the angle between the two bending plates 31 through the first hydraulic pump 50 and the second hydraulic pump 60 that are rotatably connected, so as to adjust the bending degree of the processed thin steel plate.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
