[0034] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0035] refer to Figures 1-6 This application provides a guide rail bending device, including an arc adjustment mechanism 100, a support mechanism 200 and a bending mechanism 300.

[0036] The curvature adjustment mechanism 100 includes a first connecting seat 110 and a plurality of curvature adjustment components 120 disposed on the first connecting seat 110. The plurality of curvature adjustment components 120 are arranged laterally and have vertical height differences to form the curvature required by the guide rail. Each curvature adjustment component 120 includes a fourth driving member 121 and a curvature support member 122. The fourth driving member 121 is connected to the first end of the curvature support member 122 and drives the curvature support member 122 to move vertically, so that the second ends of the plurality of curvature support members 122 form a curved surface.

[0037] Through the coordinated operation of multiple curvature adjustment components 120, the fourth drive component 121 of each curvature adjustment component 120 precisely controls the vertical movement position of the curvature support component 122, thereby making the curvature of the guide rail adjustable by the arc surface formed by the second ends of the multiple curvature support components 122, thus expanding the bending deformation capability of the guide rail.

[0038] In the arc adjustment mechanism 100 of the guide rail bending device in this embodiment, the fourth drive component 121 of each arc adjustment component 120 adopts an electric push rod, and the telescopic end of the electric push rod is fixedly connected to the first end of the arc support component 122. The electric push rod can precisely control the height position of the arc support component 122, thereby achieving more precise arc adjustment. The arc support component 122 is made of hard alloy material, and its surface is hardened to enhance wear resistance and service life.

[0039] The support mechanism 200 includes a support component 210 and a pressing member 220. Both ends of the support component 210 are hinged to the first connecting seat 110 and the pressing member 220, respectively. Two support components 210 are provided; one end of each support component 210 is connected to both ends of the first connecting seat 110 along the lateral direction, and the other end of each support component 210 is connected to both ends of the pressing member 220 along the lateral direction. The hinged design between the support component 210 and the pressing member 220 allows the support mechanism 200 to support the guide rail, preventing direct contact between the guide rail and the curvature adjustment component 120, effectively preventing wear between the guide rail and the support structure, and extending the service life of the guide rail. The pressing member 220 in the support mechanism 200 effectively protects the guide rail during bending, improving the stability of the bending process and ensuring the processing quality of the guide rail.

[0040] The support assembly 210 includes a first support base 211, a second support base 212, and a first driving member 213. The pressing member 220 includes a pressure plate 221 and a hinge seat 222 disposed on the pressure plate 221. The first support base 211 is hinged to the first connecting base 110, and the second support base 212 is hinged to the hinge seat 222. The first driving member 213 is mounted on the first support base 211 and can drive the second support base 212 to move so that the pressure plate 221 abuts against the curvature adjustment assembly 120 and produces bending deformation.

[0041] The first driving component 213 includes a first driving cylinder 214 and a first piston rod 215. The first driving cylinder 214 is disposed on the first support base 211. The first piston rod 215 is telescopically connected to the first driving cylinder 214. One end of the first piston rod 215 away from the first driving cylinder 214 is connected to the second support base 212.

[0042] The support assembly 210 also includes a first support rod 216 and a second support rod 217, which are symmetrically arranged on both sides of the first piston rod 215. The first support base 211 has a first through hole and a second through hole. One end of the first support rod 216 passes through the first through hole, and the other end is connected to the second support base 212. One end of the second support rod 217 passes through the second through hole, and the other end is connected to the second support base 212. The symmetrical arrangement of the first support rod 216 and the second support rod 217 on both sides of the first piston rod 215, connecting to the first support base 211 through the first and second through holes, and connecting to the second support base 212 at the other end, enhances the stability of the support assembly 210 and ensures that the pressure plate 221 can apply pressure evenly.

[0043] In the support mechanism 200, the first drive component 213 uses a hydraulic cylinder instead of a pneumatic cylinder. The hydraulic cylinder provides greater pressure and more stable force output, making it suitable for handling harder guide rail materials. The first support rod 216 and the second support rod 217 are made of high-strength alloy steel, enhancing the support strength and rigidity.

[0044] The bending mechanism 300 includes a bending assembly 310 and a placement rack 320 for placing the guide rail. The bending assembly 310 drives the placement rack 320 to move vertically until it abuts against the holding member 220. The holding member 220 and the guide rail on the placement rack 320 undergo bending deformation under the action of multiple curvature adjustment assemblies 120.

[0045] Both the pressure plate 221 and the placement rack 320 can deform as the guide rail is bent. Driven by the first driving member 213, the pressure plate 221 abuts against the arc support member 122 in the multiple arc adjustment components 120, thereby protecting the top of the guide rail. Furthermore, the vertical movement of the pressure plate 221 can adjust the distance between the pressure plate 221 and the placement rack 320, making it easier for the guide rail to be placed into the placement slot 321 on the placement rack 320.

[0046] The guide rail bending device also includes a frame 400 and a second drive member 500. The frame 400 includes a slide rail 410, a first mounting seat 420 and a second mounting seat 430 arranged vertically at intervals. A slider 111 is provided on the first connecting seat 110 and the slider 111 is sleeved on the slide rail 410. The second drive member 500 is installed on the first mounting seat 420 and can drive the first connecting seat 110 to move vertically. The bending assembly 310 is disposed on the second mounting seat 430.

[0047] The frame 400 is welded from thick-walled square steel, enhancing the overall structural stability. The slide rail 410 uses a linear guide rail, improving the smoothness and accuracy of the movement of the first connecting seat 110. The second driving component 500 enables the arc adjustment mechanism 100 and the support mechanism 200 to move vertically as a whole, allowing the guide rail to deform under vertical pressure.

[0048] The bending assembly 310 includes a second connecting seat 311 and a third driving member 312. The second connecting seat 311 is disposed on the second mounting seat 430, and the third driving member 312 is mounted on the second connecting seat 311 and can drive the placement rack 320 to move vertically. The third driving member 312 includes a second driving cylinder 313 and a second piston rod 314. The second driving cylinder 313 is disposed on the second connecting seat 311, and the second piston rod 314 is telescopically connected to the second driving cylinder 313. The end of the second piston rod 314 away from the second driving cylinder 313 is connected to the placement rack 320.

[0049] By adjusting the height and position of the arc support 122 controlled by the fourth drive component 121, the bending requirements of the guide rail with different arcs can be met, enhancing the adaptability and flexibility of the device. Simultaneously, the coordinated operation of the second drive component 500 and the third drive component 312 ensures precise control and stability of the guide rail bending process.

[0050] In one embodiment, multiple bending assemblies 310 are provided, arranged sequentially in the transverse direction. Each bending assembly 310 is connected to a placement rack 320. The placement rack 320 is provided with a placement groove 321, which, together with the holding member 220, forms a placement space for accommodating the guide rail. The sequential arrangement of the multiple bending assemblies 310 in the transverse direction, with each assembly connected to the placement rack 320, ensures that the guide rail receives uniform support and pressure in the transverse direction, preventing twisting or uneven deformation during bending. Containing the guide rail within the placement space thus suppresses wear on the guide rail.

[0051] The third drive component 312 in the bending mechanism 300 also uses a hydraulic cylinder instead of a pneumatic cylinder. The inner surface of the placement groove 321 on the placement rack 320 is covered with a layer of rubber material, which increases the friction with the guide rail and prevents the guide rail from sliding during the bending process.

[0052] In this embodiment, the working principle of the guide rail bending device is as follows:

[0053] First, the height of the arc support members 122 in each arc adjustment assembly 120 is adjusted by the fourth driving member 121, so that the second ends of the multiple arc support members 122 form the required arc shape. These arc adjustment assemblies 120 are arranged laterally and have vertical height differences, which can form the bending arc required by the guide rail. Next, the guide rail to be bent is placed in the placement slot 321 of the placement rack 320. The second driving member 500 drives the first connecting seat 110 to move vertically, adjusting the overall height position of the arc adjustment mechanism 100. Then, the first driving member 213 drives the second support seat 212 to move, so that the pressure plate 221 abuts against the arc adjustment assembly 120 through the hinge structure. At the same time, the third driving member 312 drives the placement rack 320 to move vertically upward, so that the guide rail on the placement rack 320 abuts against the pressure plate 221 of the holding member 220.

[0054] Under the combined action of the curvature adjustment assembly 120, the holding member 220, and the placement rack 320, the guide rail is pressed into a curved shape that matches the arc surface formed by the curvature adjustment assembly 120. The pressure plate 221 of the holding member 220 presses against the top of the guide rail, while the placement rack 320 supports the guide rail from below, thereby suppressing wear on the guide rail and ensuring that the guide rail can bend and deform evenly.

[0055] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0056] Furthermore, the use of terms such as "first," "second," and "a" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0058] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.
