DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] As Figures 1 to 6As shown in the figure, the present utility model relates to a bending angle adjustment mechanism of a hydraulic sheet metal bending machine, which includes a frame 1. A stamping mechanism 2 and a base 3 are respectively fixed on the upper and lower sides of the frame 1. A folding angle adjustment assembly 4 and an angle adjustment member 5 combined with both sides of the folding angle adjustment assembly 4 are fixed on the top of the base 3. A bending support member 6 cross-combined with the folding angle adjustment assembly 4 is also fixed on the top of the base 3; the folding angle adjustment assembly 4 can adjust the opening angle under the action of the angle adjustment member 5, so as to achieve the effect of automatic adjustment of the bending angle. The setting of the bending support member 6 can support the bottom of the sheet metal bending to maintain the accuracy of the bending.
[0025] The folding angle adjustment assembly 4 includes two U-shaped blocks 401 fixed on the top of the base 3. Two pressure-resistant plates 402 that fit with the angle adjustment member 5 are rotatably installed between the two U-shaped blocks 401; the pressure-resistant plates 402 can be conveniently flipped to adjust the inclination angle under the limitation of the U-shaped blocks 401, so as to adjust the included angle between the two pressure-resistant plates 402 on both sides. Under the action of the telescopic movement of the angle adjustment member 5, the adjusted inclination position can be limited.
[0026] The angle adjustment member 5 includes two electric push rods 501. A support rod 502 that fits with the side surface of the pressure-resistant plate 402 is connected between the upper ends of the two electric push rods 501; the setting of the support rod 502 can maintain the fitting degree with the pressure-resistant plate 402 at different heights, so as to maintain the stability of the support for the pressure-resistant plate 402 under the action of the electric push rod 501.
[0027] In an embodiment of the present utility model, the bending support member 6 includes a U-shaped plate 601 inverted on the top of the base 3. A U-shaped groove 602 is formed on the side wall of the U-shaped plate 601. A slot 403 intersecting and combining with the U-shaped groove 602 is formed at the bottom of the wall of the pressure-resistant plate 402. An arc-shaped pressing plate 404 is fixedly provided at the top of the side of the pressure-resistant plate 402 close to the angle adjusting member 5. An arc-shaped groove 603 is formed at the top of the U-shaped plate 601. An arc-shaped cushion block 604 flush with the top of the U-shaped plate 601 is placed inside the arc-shaped groove 603. An insertion block 605 combined with the U-shaped groove 602 is fixedly provided at the bottom of the arc-shaped cushion block 604; through the cross design of the U-shaped groove 602 and the slot 403, the influence on the flipping angle of the pressure-resistant plate 402 can be reduced. At the same time, the setting of multiple bending support members 6 can reduce the influence on the forming of the extrusion angle when the sheet material is extruded, maintain the strength of the extrusion during bending. The setting of the arc-shaped pressing plate 404 can define the range of the top support of the pressure-resistant plate 402 when placing the sheet material, and can increase the gravity point at the top, so that the pressure-resistant plate 402 can tilt outward by its own weight, further improving the flexibility of angle adjustment. The cooperation between the arc-shaped groove 603 and the arc-shaped cushion block 604 can form an arc-shaped concave surface while keeping the surface level, so that it can be applied to the need of arc bending of the sheet material, improving the flexibility of the cooperation between structures. At the same time, a movable gap is reserved between the arc-shaped pressing plate 404 and the support rod 502, which can reserve a gap for the flipping of the pressure-resistant plate 402, and can also limit the upward movement distance of the support rod 502, further improving the cooperation effect between the two side pressing plates 402 and the stamping part.
[0028] In an embodiment of the present utility model, an annular connecting member 405 is fixedly provided on the outer wall of the pressure-resistant plate 402 close to the angle adjusting member 5. Connecting ring blocks 503 aligned with the position of the annular connecting member 405 are fixedly provided at both ends of the support rod 502. An elastic pull belt 7 is connected between the annular connecting member 405 and the connecting ring block 503; through the structure of the elastic pull belt 7 connected between the annular connecting member 405 and the connecting ring block 503, the stability of the fit between the pressure-resistant plate 402 and the support rod 502 can be further improved. At the same time, the elastic telescopic characteristic of the elastic pull belt 7 can reduce the influence on the limit of the pressure-resistant plate 402, improving the cooperation effect between the two.
[0029] In an embodiment of the present utility model, a plurality of limiting blocks 406 are annularly arranged on the outer side of the annular connecting member 405 and close to the pressure-resistant plate 402. The side end of the limiting block 406 is close to the center of the elastic pull belt 7; the design of the limiting block 406 can limit the installation position of the elastic pull belt 7, and at the same time does not affect the disassembly and assembly operation of the elastic pull belt 7, with flexible cooperation.
[0030] Working principle: This embodiment provides a bending angle adjustment mechanism for a hydraulic sheet metal bending machine. During use, the telescopic lengths of the angle adjustment members 5 on both sides are adjusted according to the required bending angle of the sheet metal, thereby adjusting the included angle between the pressure-resistant plates 402 on both sides to be the same as the required bending angle. Then, the sheet metal can be placed on the top of the pressure-resistant plates 402. After placement, the sheet metal can be extruded through the operation of the stamping mechanism 2. The pressed part bends into the included angle between the pressure-resistant plates 402 on both sides, so that the extrusion head cooperates with the inner wall of the pressure-resistant plate 402 to bend the sheet metal into the required angle, completing the sheet metal bending operation. Through such an operation, the appropriate bending angle can be simply adjusted according to different requirements, reducing the time required for angle adjustment. At the same time, the bending support member 6 structure provided on the top of the base 3 and cooperating with the folding angle adjustment assembly 4 can play a role in bottom support when the sheet metal is extruded and bent, maintaining the stability of the bending angle. The cross cooperation of the slot 403 and the U-shaped slot 602 does not affect the flipping of the pressure-resistant plate 402, and the arc-shaped slot 603 opened at the top of the U-shaped plate 601 can be used for the bending of the arc angle. By removing the arc-shaped cushion block 604, the arc-shaped slot 603 can be exposed, and an arc included angle can be formed in cooperation with the pressure-resistant plate 402, further improving the flexibility of sheet metal bending. The cooperation of the overall structure can enhance the bending effect.
