[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1 - Figure 7 A bending sheet metal part bending equipment includes: a bending machine body 1, an angle adjustment component 4, and a limiting component 6. The bending machine body 1 includes a hydraulic drive module and a control module. A moving component 5 is provided at the outer end of the bending machine body 1. The angle adjustment component 4 includes a turntable 42. A stop block 44 is fixedly installed on the top of the turntable 42. A scale ring 45 is sleeved on the outer surface of the turntable 42. The limiting component 6 includes a rotating seat 62 and a mounting seat 61. The rotating seat 62 is fixedly installed at the bottom of the turntable 42 and is installed inside the mounting seat 61. An annularly distributed limiting block 66 is fixedly installed inside the mounting seat 61. An annular groove 63 adapted to the limiting block 66 is opened on the outer surface of the rotating seat 62. The rotating seat 62 is rotated and installed inside the mounting seat 61 through the annular groove 63 and the limiting block 66. The turntable 42 is rotated and the angle is adjusted by the rotation of the rotating seat 62.
[0033] The bending machine body 1 is equipped with a bending blade 2 and a bending die 3 at its outer end. The bending blade 2 and the bending die 3 are compatible with each other, and the surface of the turntable 42 is flush with the bending die 3.
[0034] The device in this solution is mainly used for bending sheet metal parts. The bending machine body 1 is mainly composed of a hydraulic drive module and a control module. The hydraulic drive module is mainly composed of a hydraulic pump, a control valve group, and a hydraulic cylinder. It is mainly used to drive the bending blade 2 installed on the bending machine body 1 to move up and down. A bending die 3 is also installed on the bending machine body 1. The bending die 3 is mainly used to work in conjunction with the bending blade 2 to bend the sheet metal parts by pressure. The control module is mainly responsible for accurately coordinating all actions to ensure that the bending process is efficient, accurate, and repeatable. It controls the lifting speed, stroke, and stop position of the hydraulic cylinder so that the various components on the bending machine body 1 can work in coordination.
[0035] A movable component 5 is installed at the outer end of the bending machine body 1. The angle adjustment component 4 moves and adjusts its position on the movable component 5. Its turntable 42 can rotate through the limiting component 6. At this time, the reference scale ring 45 and the indicator head 46 cooperate to adjust to the corresponding angle. Then, the edge of the sheet metal part is pressed against the side of the stop block 44, so that the sheet metal part can follow the turntable 42 to adjust the angle. This allows the sheet metal part to be bent at different tilt angles, improving the accuracy of diagonal bending.
[0036] Please see Figure 4 and Figure 5 The angle adjustment assembly 4 also includes a mounting plate 41 and an indicator head 46. The indicator head 46 is fixedly installed on the outer end of the mounting base 61. The indicator head 46 is adapted to the scale ring 45. Anti-slip plates 43 are evenly distributed on the outer end of the turntable 42.
[0037] The angle adjustment component 4 in this solution is mainly used to guide the sheet metal parts, allowing them to be bent at an angle by the bending machine body 1. The mounting plate 41 mainly supports the turntable 42 and the limiting component 6, and allows them to move. A stop block 44 is fixed on the top of the turntable 42. The stop block 44 is semi-circular. When the sheet metal parts are on the turntable 42, their edges can be pressed against the side of the stop block 44, which serves as a guide, allowing the sheet metal parts to accurately follow the rotation angle of the turntable 42. Multiple anti-slip plates 43 are installed on the turntable 42 at equal intervals. The anti-slip plates 43 are made of rubber and mainly serve to increase friction, so that when the sheet metal parts are placed on the turntable 42, they come into contact with the anti-slip plates 43 and are not easy to slip.
[0038] A scale ring 45 is fixed around the turntable 42. Angle scales are engraved on the outer surface of the scale ring 45, which can rotate with the turntable 42. An indicator head 46 is fixed at the outer end of the mounting base 61. The arrow on the indicator head 46 is fixed. When the edge of the sheet metal part is pressed against the stop block 44, the sheet metal part is perpendicular to the bending machine body 1. At this time, the bending angle is parallel or perpendicular to the edge of the sheet metal part. When different bending angles are required, the turntable 42 can be rotated so that the sheet metal part can rotate with it. By observing the position of the arrow on the indicator head 46 on the scale ring 45, the corresponding angle can be rotated. Then, the edge of the sheet metal part is pressed against the edge of the stop block 44, so that the sheet metal part can also be rotated to the corresponding angle. This allows it to be adjusted to the corresponding angle when bent by the bending machine body 1, which is convenient for tilting bending.
[0039] Please see Figure 4 - Figure 7 The limiting component 6 also includes a threaded rod 65, a mounting base 61 is fixedly installed on the outer end of the mounting plate 41, one end of the threaded rod 65 is rotatably connected to a movable block 67, and the other end of the threaded rod 65 is fixedly installed with a lever 64.
[0040] The mounting base 61 has a threaded groove on its inner side. The threaded rod 65 is adapted to the threaded groove, and the movable block 67 is adapted to the annular groove 63. The movable block 67 abuts against the inner side of the annular groove 63 to form a limit.
[0041] The outer end of the limiting block 66 has an inclined surface 69, and the outer end of the inclined surface 69 is equipped with equally spaced balls 68. The balls 68 abut against the inner side of the annular groove 63 to reduce rotational friction.
[0042] The limiting component 6 in this solution is mainly used to support the rotation of the angle adjusting component 4 and to limit and fix it after rotation. The mounting base 61 is fixed on the mounting plate 41, and the rotating base 62 is fixed on the rotating base 62, which can drive the rotating base 62 to rotate. The inner side of the mounting base 61 is hollow, and the rotating base 62 is installed inside the mounting base 61. An annular groove 63 is opened on the outer edge of the rotating base 62, and the annular groove 63 surrounds the entire outer edge of the rotating base 62. Multiple [unclear] are fixed on the inner side of the mounting base 61. The limiting blocks 66 are distributed in annularly at equal intervals. The limiting blocks 66 have inclined surfaces 69 on both the upper and lower sides. The limiting blocks 66 can be adapted to the annular grooves 63 by the inclined surfaces 69. At the same time, multiple balls 68 are rotatably installed on the inclined surfaces 69. The balls 68 abut against the inner side of the annular grooves 63, thereby reducing the resistance when the rotating seat 62 rotates. Meanwhile, the trapezoidal shape of the limiting blocks 66 can be locked in the annular grooves 63 on the rotating seat 62, so that it will not detach from the mounting base 61, and the rotating seat 62 can only rotate.
[0043] A threaded groove is formed at the outer end of the mounting base 61. A threaded rod 65 is threadedly connected to the threaded groove. One end of the threaded rod 65 extends into the threaded groove and is rotatably mounted with a movable block 67. A limiting block 66 has the same shape as the limiting block 67 and is adapted to the annular groove 63 on the rotating base 62, allowing the rotating base 62 to rotate. However, the movable block 67 can move. A lever 64 is fixed at the other end of the threaded rod 65. By rotating the lever 64, the threaded rod 65 can be driven to rotate in the threaded groove. At this time, the movable block 67 can move into the annular groove 63, so that the movable block 67 can be tightly pressed against the inner side. By increasing the friction between the movable block 67 and the inner side of the annular groove 63, the rotating base 62 can be limited. After the turntable 42 is adjusted at the angle, it can be fixed.
[0044] Please see Figure 2 and Figure 3 The moving component 5 includes two slide rods 51 and two sets of sliding sleeves 55. The two slide rods 51 are fixedly installed on the outer end of the bending machine body 1, and the two sets of sliding sleeves 55 are fixedly installed on the bottom end of the mounting plate 41. The sliding sleeves 55 are slidably connected to the slide rods 51. An mounting sleeve 52 is fixedly installed between one set of sliding sleeves 55. The mounting sleeve 52 is sleeved on the outer end of the slide rod 51. A fitting sleeve 53 is rotatably connected to the outer end of the mounting sleeve 52. A friction pad 54 is installed on the inner side of the fitting sleeve 53. The friction pad 54 abuts against the slide rod 51 to form a limit.
[0045] The movable component 5 in this solution is mainly used to allow the angle adjustment component 4 and the limiting component 6 to move laterally to adjust their positions. Four sliding sleeves 55 are grouped in pairs. Two sliding rods 51 are fixed to the outer end of the bending machine body 1, and the two sliding rods 51 are arranged in parallel. All four sliding sleeves 55 are fixed to the bottom of the mounting plate 41. A mounting sleeve 52 is fixed between two sliding sleeves 55. The mounting sleeve 52 is also fitted onto the outer end of the sliding rod 51, allowing for sliding movement. A notch is opened at the outer end of the mounting sleeve 52, and a connecting sleeve 53 is rotatably connected at the notch. Both the connecting sleeve 53 and the mounting sleeve 52 have... Connecting blocks are installed, and two connecting blocks can be fixed together by using bolts. At this time, the sleeve 53 will cover the notch of the mounting sleeve 52 to form a fit. A friction pad 54 made of rubber is fixed inside the sleeve 53. When the sleeve 53 covers the mounting sleeve 52, the friction pad 54 will abut against the slide rod 51. The friction force can fix the mounting sleeve 52 and prevent it from moving. When it is necessary to adjust the position of the angle adjustment component 4 and the limit component 6, the bolts can be loosened. By moving component 5, the angle adjustment component 4 and the limit component 6 can be moved to the appropriate position.
[0046] Working principle: When the angle needs to be adjusted during bending, the turntable 42 can be rotated to observe the position of the arrow on the scale ring 45. Rotate to the corresponding angle, and then rotate the lever 64 to drive the threaded rod 65 to rotate in the threaded groove. At this time, the movable block 67 can be tightly pressed against the inner side of the annular groove 63, and the rotating seat 62 is limited by friction. Then, the edge of the sheet metal part is pressed against the edge of the stop block 44, so that the sheet metal part can also be rotated to the corresponding angle and bent by the bending machine body 1.
