DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 to Figure 2 As shown, a CNC bending device is designed for bending some small parts of new energy vehicles. The bending device includes a bending operation table 1 in terms of structural design. A first bending limit seat 11 is slidably provided on one side of the top surface of the bending operation table 1, and a second bending limit seat 12 is movably provided on the other side of the top surface of the bending operation table 1. The first bending limit seat 11 and the second bending limit seat 12 move relatively close to each other and are used to limit the new energy vehicle panel that needs to be bent; a bending tool 2 is movably provided above the bending operation table 1 for bending the new energy vehicle panel limited by the first bending limit seat 11 and the second bending limit seat 12. By placing the new energy vehicle panels that need to be bent (some relatively small panels) between the first bending limit seat 11 and the second bending limit seat 12, these new energy vehicle panels are limited by controlling the first bending limit seat 11 and the second bending limit seat 12, and then the bending tool 2 is controlled to bend these new energy vehicle panels.

[0022] Further, in the embodiment, a bending connection tool holder 21 is provided at the top of the bending tool 2, and the bending tool 2 and the bending connection tool holder 21 are detachably connected by bolts; a connecting arm 22 is connected to the top of the bending connection tool holder 21, and both ends of the connecting arm 22 are respectively connected to hydraulic cylinders for driving the connecting arm 22 to rise and fall, and the hydraulic cylinders are connected to the base 3 through connecting columns 23; the bending operation platform 1 is arranged between the two connecting columns 23 and connected to the connecting columns 23 by bolts. In addition, the first bending limit seat 11 is slidably arranged with the top surface of the bending operation platform 1 through an electric slide rail; the second bending limit seat 12 is slidably arranged with the top surface of the bending operation platform 1, and the second bending limit seat 12 is connected to a driving mechanism for driving the second bending limit seat 12 to slide along the top surface of the bending operation platform 1. At the same time, a conveying seat 13 is connected to the end of the bending operation table 1 away from the second bending limit seat 12, which is used to facilitate the movement of the new energy vehicle panel that needs to be bent between the first bending limit seat 11 and the second bending limit seat 12. When it is necessary to bend some smaller connecting panels of new energy vehicles, the panel is moved between the first bending limit seat 11 and the second bending limit seat 12 of the design through the conveying seat 13, and then the first bending limit seat 11 and the second bending limit seat 12 are adjusted and controlled to "relatively move" to limit the limit panel below the bending tool 2; then, by respectively controlling the hydraulic cylinders at both ends of the connecting arm 22 to move "synchronously downward", the bending tool 2 connected to the connecting arm 22 through the bending connecting tool seat 21 is driven to move downward toward the position of the limit panel, so that the bending tool 2 bends the panel limited between the first bending limit seat 11 and the second bending limit seat 12. It should be noted here that the bending tool 2 and the bending connecting tool seat 21 are detachably connected by bolts, that is, the "shape" of the "different types" of bending tools 2 can be replaced as needed, so as to bend the plate limited between the first bending limit seat 11 and the second bending limit seat 12 into the required "shape structure".

[0023] Furthermore, in the embodiment, the driving mechanism of the arrangement includes a first driving connection block 41, a driving curved rod 42, and a second driving connection block 43; the first driving connection block 41 is arranged at the bottom end of the bending operation table 1, and is hinged to the bottom end of the bending operation table 1 through a hinge seat, and a movable rod is connected to the top end of the first driving connection block 41, and one end of the movable rod away from the first driving connection block 41 can movably pass through the bending operation table 1 and is connected to the second bending limit seat 12, and the other end of the first driving connection block 41 is hinged to one end of the driving curved rod 42, and one end of the driving curved rod 42 away from the first driving connection block 41 is hinged to the base 3 through a hinge seat, and the middle part of the driving curved rod 42 is hinged to one end of the second driving connection block 43, and one end of the second driving connection block 43 away from the driving curved rod 42 is connected to a movable mechanism for controlling the movement of the second driving connection block 43. At the same time, the movable mechanism of the design includes a movable block 44, which can be horizontally slidably connected to a movable seat 45, the bottom end of the movable seat 45 is connected to the base 3 through a connecting steel plate, one end of the movable block 44 is hinged to the second drive connecting block 43, and the other end of the movable block 44 is hinged to a horizontal movable rod 46; the horizontal movable rod 46 is connected to the horizontal sliding seat 4, and the bottom end of the horizontal sliding seat 4 is slidably arranged with the base 3 through an electric slide rail. In the embodiment, the electric slide rail 9 (existing technology) is controlled to drive the horizontal sliding seat 4 to "move horizontally" along the base 3, and the base 3 in turn drives the horizontal movable rod 46 to move. The horizontal movable rod 46 moves, and the movable block 44 connected to the end of the horizontal movable rod 46 is pushed to "move on the surface" along the movable seat 45, and then the movable seat 45 drives the second driving connection block 43 hinged at the other end to drive the driving curved rod 42 to "move", thereby driving the curved rod 42 to move, driving the first driving connection block 41 connected at the top to move, and the first driving connection block 41 in turn drives the movable rod connected to the top 9 (hinged) to move, so that the movable rod drives the second bending limit seat 12 connected at the other end (hinged) to "move", so that the second bending limit seat 12 can be driven to move along the surface of the bending operating table 1, and the relative movement (including relative proximity and relative distance) of the first bending limit seat 11 and the second bending limit seat 12 can be realized, so as to realize "limit tightening" or "loosening" of the plate placed between the first bending limit seat 11 and the second bending limit seat 12, so as to facilitate the bending processing of the plate. From the perspective of the entire bending device structural design, the bending device can not only solve the problem that large-scale bending equipment is inconvenient to bend some new energy vehicle panels, but also save materials and resources and save processing costs through the bending device.
