Bending mechanism for cabinet processing

Abstract

This utility model belongs to the technical field of bending equipment, and particularly to a bending mechanism for chassis processing. It includes a base plate, a central seat fixedly installed at the center of the top of the base plate, a limiting seat installed on the top of the central seat, and a bending groove formed on the top of the limiting seat. Multiple symmetrically distributed fixed seats are fixedly installed on the top of the base plate, and a telescopic rod is fixedly installed on the top of each fixed seat. This chassis processing bending mechanism uses a starting cylinder to drive a bending head downwards to contact and compress the chassis sheet metal. Under the limiting action of the bending groove, the chassis sheet metal is bent. Simultaneously, both sides of the chassis sheet metal rise synchronously and slide within the limiting groove, driving the limiting plate to rotate. This not only limits the two ends of the chassis sheet metal but also prevents deformation at both ends, improving the flatness and stability of the chassis sheet metal during bending, and also increasing the bending accuracy.

Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically to a bending mechanism for chassis processing. Background Technology

[0002] Currently, most equipment is installed inside a cabinet, which is basically made of metal sheet. In order to meet the different shapes and sizes of equipment, the sheet metal needs to be bent during the production of the cabinet. Therefore, bending equipment is needed to bend the sheet metal of the cabinet. However, the current bending equipment has a relatively simple structure, and its stability and bending accuracy need to be improved.

[0003] Patent CN220346926U discloses a bending mechanism for high-precision chassis processing, specifically relating to the field of bending equipment technology. It includes a worktable with a gantry frame on top, and a cylinder on top of the gantry frame. This invention, through a connecting mechanism, allows for convenient and quick disassembly and installation of the bending head for replacement. A fixing component, in conjunction with a clamping block structure, limits and fixes the chassis sheet metal, preventing displacement during bending and thus ensuring processing accuracy. While the aforementioned patent achieves limiting the sheet metal during bending, the sides of the chassis sheet metal tend to tilt during bending. The fixed length of the moving block causes deformation at both ends of the chassis during bending, and the location and angle of this deformation are uncertain, thus affecting the structural flatness of the bent chassis sheet metal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending mechanism for chassis processing, which solves the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending mechanism for chassis processing, comprising a base plate, a center seat fixedly installed at the middle position of the top of the base plate, a limiting seat installed on the top of the center seat, a bending groove formed on the top of the limiting seat, multiple symmetrically distributed fixing seats fixedly installed on the top of the base plate, a telescopic rod fixedly installed on the top of the fixing seats, a fixing rod fixedly installed on the top of the telescopic rod, a limiting mechanism fixedly installed on the top of the fixing rod, the limiting mechanism comprising a limiting plate rotatably installed on the top of the telescopic rod, a limiting groove formed on the side of the limiting plate, a fixing frame fixedly installed on the top of the base plate, a cylinder installed at the bottom of the fixing frame, and a bending head fixedly installed at the bottom of the cylinder and directly above the bending groove.

[0006] As a preferred embodiment of this utility model, the top of the center seat is provided with a top groove, the bottom of the limiting seat is fixedly installed with a snap-fit ​​block that snaps into the top groove, the bottom of the cylinder is inserted into the top of the bending head, and a magnetic block is installed at the connection between the cylinder and the bending head.

[0007] As a preferred technical solution of this utility model, there are multiple fixed seats symmetrically distributed on both sides of the limiting seat, and the openings of the multiple limiting grooves all face the limiting seat.

[0008] As a preferred embodiment of the present invention, the limiting mechanism further includes a fixed plate fixedly installed on the top of the fixed rod. Two symmetrically distributed side plates are fixedly installed on the top of the fixed plate, and a rotating rod is rotatably installed between the two side plates. The limiting plate is fixedly sleeved on the outside of the rotating rod and located between the two side plates.

[0009] As a preferred technical solution of this utility model, the initial position of the bottom of the inner side of the limiting groove is on the same horizontal plane as the top of the limiting seat.

[0010] As a preferred technical solution of this utility model, the angle of the bending groove matches the bottom angle of the bending head, and the two sides of the bending groove and the top of the limiting seat are in a horizontal state.

[0011] Compared with the prior art, this utility model provides a bending mechanism for chassis processing, which has the following beneficial effects:

[0012] 1. The bending mechanism of this chassis uses a starting cylinder to drive the bending head downward to contact and squeeze the chassis sheet metal. Under the limiting action of the bending groove, the chassis sheet metal is bent. At the same time, the two sides of the chassis sheet metal will rise synchronously and slide in the limiting groove, while driving the limiting plate to rotate. In this way, the two ends of the chassis sheet metal can be limited, and deformation of the two ends of the chassis sheet metal can be avoided, improving the flatness and stability of the chassis sheet metal during the bending process, and improving the bending accuracy of the chassis sheet metal.

[0013] 2. The bending mechanism of this chassis can be modified by replacing different models of limit seats and bending heads. That is, the bending angle of the bending groove of the limit seat is different for different models, so that the snap-fit ​​block is snapped into the top groove, which facilitates bending the chassis plate at different angles.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 In this embodiment: the bending mechanism for chassis processing includes a base plate 1, a center seat 4 fixedly installed at the middle position of the top of the base plate 1, a limit seat 5 installed on the top of the center seat 4, a bending groove 51 opened on the top of the limit seat 5, a plurality of symmetrically distributed fixed seats 3 fixedly installed on the top of the base plate 1, a telescopic rod 8 fixedly installed on the top of the fixed seat 3, a fixed rod 9 fixedly installed on the top of the telescopic rod 8, a limit mechanism 10 fixedly installed on the top of the fixed rod 9, the limit mechanism 10 includes a limit plate 104 rotatably installed on the top of the telescopic rod 8, a limit groove 105 opened on the side of the limit plate 104, a fixed frame 2 fixedly installed on the top of the base plate 1, a cylinder 6 installed at the bottom of the fixed frame 2, and a bending head 7 fixedly installed at the bottom of the cylinder 6 and directly above the bending groove 51.

[0022] The two sides of the chassis panel to be bent are inserted into the limiting grooves 105 respectively, so that the limiting plate 104 is in a horizontal state. At the same time, the bottom of the chassis panel is attached to the top of the limiting seat 5. The cylinder 6 is activated to drive the bending head 7 to move downward to contact and squeeze the chassis panel. Under the limiting action of the bending groove 51, the chassis panel is bent. At the same time, the two sides of the chassis panel will rise synchronously and slide in the limiting grooves 105, while driving the limiting plate 104 to rotate. In this way, the two ends of the chassis panel can be limited, and deformation of the two ends of the chassis panel can be avoided, improving the flatness and stability of the chassis panel during the bending process, and improving the bending accuracy of the chassis panel.

[0023] In a preferred embodiment, the top of the center seat 4 is provided with a top groove 41, and the bottom of the limiting seat 5 is fixedly installed with a snap-fit ​​block 52 that snaps into the top groove 41. The bottom of the cylinder 6 is inserted into the top of the bending head 7, and a magnetic block is installed at the connection between the cylinder 6 and the bending head 7. By replacing the limiting seat 5 and the bending head 7 with different models, that is, the bending angle of the bending groove 51 of the limiting seat 5 is different, so that the snap-fit ​​block 52 snaps into the top groove 41, which facilitates bending the chassis plate at different angles.

[0024] In a preferred embodiment, there are multiple fixed seats 3 symmetrically distributed on both sides of the limiting seat 5, and the openings of the multiple limiting grooves 105 all face the limiting seat 5, so as to realize multi-directional limiting of the chassis plate and facilitate the installation of the chassis plate in the limiting grooves 105.

[0025] Example 2

[0026] Please see Figure 1-4 In this embodiment, the limiting mechanism 10 further includes a fixed plate 101 fixedly installed on the top of the fixed rod 9. Two symmetrically distributed side plates 102 are fixedly installed on the top of the fixed plate 101. A rotating rod 103 is rotatably installed between the two side plates 102. The limiting plate 104 is fixedly sleeved on the outside of the rotating rod 103 and located between the two side plates 102. During the bending process of the chassis plate, the two ends of the plate will warp up and shrink relatively. At this time, the limiting mechanism 10 will be lifted, driving the fixed rod 9 to rise. At the same time, the telescopic end of the telescopic rod 8 will extend. Thus, the chassis plate will slide in the limiting groove 105. At the same time, the limiting plate 104 will rotate to meet the bending action of the chassis plate. While limiting the chassis plate, it ensures that other parts of the chassis plate do not deform.

[0027] In a preferred embodiment, the initial position of the bottom of the inner side of the limiting groove 105 is on the same horizontal plane as the top of the limiting seat 5, ensuring that the chassis plate is in a horizontal state before bending.

[0028] In a preferred embodiment, the angle of the bending groove 51 matches the bottom angle of the bending head 7, and the two sides of the bending groove 51 and the top of the limiting seat 5 are in a horizontal state, which improves the stability of the chassis plate before bending and the bending.

[0029] The working principle and usage process of this utility model are as follows: The operator inserts both sides of the chassis plate to be bent into the limiting groove 105, so that the limiting plate 104 is in a horizontal state. At the same time, the bottom of the chassis plate is attached to the top of the limiting seat 5. The cylinder 6 is activated to drive the bending head 7 to move downward to contact and squeeze the chassis plate. Under the limiting action of the bending groove 51, the chassis plate is bent. The two ends of the plate will bend and relatively contract. At this time, the limiting mechanism 10 will be lifted, driving the fixing rod 9 to rise. At the same time, the telescopic end of the telescopic rod 8 will extend. Thus, the chassis plate will slide in the limiting groove 105. At the same time, the limiting plate 104 will rotate to meet the bending action of the chassis plate. While limiting the chassis plate, it ensures that other parts of the chassis plate do not deform. In this way, the two ends of the chassis plate can be limited, and deformation of the two ends of the chassis plate can be avoided, improving the flatness and stability of the chassis plate during the bending process, and improving the bending accuracy of the chassis plate.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
