Furthermore, existing CNC bending machines, when bending thick sheets, cannot achieve proper alignment between the upper and lower pressure plates due to their fixed positions, hindering successful bending of thick sheets and necessitating improvement.

The lower edge of the upper pressure frame 2 is equipped with a pressure forming cutter 6. The upper pressure frame rotating seat 2-1 is integrally formed at the lower right end of both sides of the upper pressure frame 2. The upper pressure frame hinge seat 2-2 is integrally formed at the upper front end of both sides of the upper pressure frame 2. The upper pressure frame drive hinge seat 2-2 and the upper frame hinge seat 1-1 are both through-mounted with fixed shafts 8. The upper and lower ends of the clamping drive cylinder 3 are rotatably connected to the upper and lower fixed shafts 8 respectively, which can drive the upper pressure frame 2 to rotate around the fixed support shaft seat mechanism 10.

[0031] The fixed support shaft seat mechanism 10 includes:

[0032] Fixing base 10-1 is integrally formed on the upper front end of both sides of the frame 1;

[0033] Adjusting seat 10-2 is threadedly connected to adjusting screw 7-4 and is slidably disposed in fixed seat 10-1; the left and right walls of adjusting seat 10-2 move against the left and right inner walls of fixed seat 10-1, which plays a role in limiting and guiding the translation of adjusting seat 10-2.

[0034] There are two output shafts 10-3, which are respectively connected to the outer side wall of the adjusting seat 10-2 and are movably inserted into the strip hole opened in the outer side wall of the fixed seat 10-1; the output shafts 10-3 are connected to the upper pressure frame rotating seat 2-1; the upper pressure frame 2 rotates around the output shafts 10-3 to open and close.

[0035] The flip-plate bending assembly 5 includes:

[0036] The bending plate 5-1 has an integrally formed bending edge 5-4 on one side adjacent to the pressing and forming tool 6. The front and rear sides of the bending plate 5-1 have integrally formed adjusting edges 5-3. The adjusting edges 5-3 are provided with a plurality of positioning holes. The positioning screws 5-7 are threaded into the positioning holes.

[0037] Two bending plate fixing brackets 5-2 are symmetrically arranged on the front and rear sides of the bending plate 5-1. The adjusting edge 5-3 is movably mounted in a groove on the surface of the bending plate fixing bracket 5-2. The end of the positioning screw 5-7 abuts against the bending plate fixing bracket 5-2. The upper end of the bending plate fixing bracket 5-2 is rotatably connected to the fixed shaft 8 located in the upper frame hinge seat 1-1, and is hinged to the lower end of the pressing drive cylinder 3. Position: The lower end of the pressing drive cylinder 3 is located in the upper slot of the bending plate fixing frame 5-2; the lower side of the bending plate fixing frame 5-2 is integrally formed with a bending plate fixing frame hinge seat 5-8, and two fixed shafts 8 are respectively installed through the lower frame hinge seat 1-2 and the bending plate fixing frame hinge seat 5-8.

[0038] Push screw 5-5, which is threadedly installed on the side wall of bending plate fixing frame 5-2, with its inner end in movable contact with the side of adjusting edge 5-3; after loosening the nut on pull screw 5-6, rotate push screw 5-5 and move it inward in the side wall of bending plate fixing frame 5-2, thereby pushing adjusting edge 5-3, pushing bending plate 5-1 towards the pressing forming tool 6; after pushing into place, tighten the nut on pull screw 5-6, and at the same time use several positioning screws 5-7 to position adjusting edge 5-3;

[0039] Pull screw 5-6, whose inner end moves through the left side wall of bending plate fixing frame 5-2 and connects to the side of adjusting edge 5-3, and a nut is threaded onto pull screw 5-6; rotate push screw 5-5 away from adjusting edge 5-3, then rotate the nut on pull screw 5-6 to adjust pull screw 5-6 to move outward, thereby pulling adjusting edge 5-3, pulling bending plate 5-1 away from pressing forming tool 6; after being pulled into place, several positioning screws 5-7 are used to position adjusting edge 5-3; pull screw 5-6 and push screw 5-5 cooperate to achieve parallelism adjustment between bending plate 5-1 and pressing forming tool 6;

[0040] The eccentricity adjustment component 7 includes:

[0041] Servo motor 7-1, wherein the servo motor 7-1 is mounted on the front and rear outer side walls of the frame 1;

[0042] Two speed reducers 7-2 are installed on the upper rear ends of both sides of the frame 1. The input end of the right speed reducer 7-2 is connected to the output end of the servo motor 7-1, and one output end of the right speed reducer 7-2 is connected to the input end of the left speed reducer 7-2 via a synchronous shaft 7-3, so that the servo motor 7-1 works synchronously with the speed reducers 7-2 on both sides. An adjusting screw 7-4 is connected to the other output end of the right speed reducer 7-2, and an adjusting screw 7-4 is also connected to one output end of the left speed reducer 7-2. The adjusting screw 7-4 is movably installed through the fixed base 10-1.

[0043] When using this invention, by controlling the extension of the clamping drive cylinder 3, the upper pressure frame 2 is driven to rotate and open around the output shaft 10-3, and then the sheet metal is pushed from the feeding platform 9 onto the frame 1, so that the part to be bent is positioned below the pressing and forming cutter 6. At this time, the clamping drive cylinder 3 is retracted, driving the upper pressure frame 2 to rotate, so that the pressing and forming cutter 6 presses on the sheet metal (e.g., ...). Figure 1 (As shown in the diagram); Next, by controlling the extension of the tilting drive cylinder 4, the tilting bending assembly 5 is driven to rotate around the fixed axis 8 in the upper frame hinge seat 1-1. During the rotation, the bending edge 5-4 works in conjunction with the pressing and forming cutter 6 to achieve the bending operation of the sheet metal; after the bending is completed, the tilting drive cylinder 4 is retracted, causing the tilting bending assembly 5 to rotate vertically (as shown in the diagram). Figure 1 (as shown in the image)

[0044] Before bending, the position of the bending plate 5-1 can be adjusted by pulling the screw 5-6 and pushing the screw 5-5 to ensure that the bending edge 5-4 is parallel to the pressing and forming tool 6. After the parallelism is adjusted, several positioning screws 5-7 are used to cooperate with the positioning holes on the adjusting edge 5-3 and abut against the bending fixing frame 5-2 to further position the bending plate 5-1.

[0045] Before bending a thick plate, the servo motor 7-2 is started, driving the reducer 7-2 to work, which in turn drives the adjusting screw 7-4 to rotate. The adjusting screw 7-4 drives the adjusting seat 10-2 to move a small distance backward within the fixed seat 10-1, thereby moving the upper pressure frame 2 backward as a whole, and moving the pressure forming cutter 6 backward, so that the pressure forming cutter 6 and the front edge of the frame 1 (bending station) are misaligned. Then, the electromagnetic brake on the servo motor 7-2 is used to lock the servo motor 7-2 to prevent it from reversing. When bending a thick plate, this provides a certain amount of clearance for the plate thickness, making it easier to successfully bend the thick plate.

[0046] Compared with the prior art, the beneficial effects of this utility model are:

[0047] The set clamping drive cylinder, in conjunction with the rotating upper pressure frame, realizes a rotating arm-type pressing structure. This rotating arm pressing replaces vertical pressing, improving flexibility and eliminating spatial constraints. Moreover, for bending and positioning thin plates, the impact force is small, increasing the clamping force during plate bending and effectively ensuring the consistency of the bending angle of the flip plate.

[0048] The eccentric drive component is used to drive the upper pressure frame to move, so that the pressure forming tool and the bending station of the frame are misaligned, which meets the clearance space when bending thick plates, realizes the bending of thick plates, meets the pressing of different plate thicknesses, and is suitable for the flanging and bending process requirements of plates of different thicknesses.

[0049] The bending plate allows for parallelism adjustment, improving the accuracy of plate bending.

[0050] The lower end of the clamping drive cylinder and the upper end of the flip-plate bending assembly share a fixed shaft, which improves the rotational stability of both.

[0051] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
