[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention.

[0028] like Figure 1-8 As shown, this embodiment discloses a high-reliability sheet metal processing equipment, including a base 2 with a controller 1, a lower die 21 and an upper die 22 which is lifted and lowered relative to the lower die 21 are arranged on the base 2, a die assembly 23 is arranged on the lower die 21, a bending knife 24 is arranged on the upper die 22, the die assembly 23 is a die which is detachably arranged on the lower die 21, after the staff places the metal sheet to be bent horizontally on the die assembly 23, the equipment is started through the controller 1, and the upper die 22 drives the bending knife 24 to move downward, during the bending process, the blade head of the bending knife 24 will be inserted into the groove of the die assembly 23, thereby realizing the bending of the metal sheet.

[0029] Among them, the controller 1 includes a PLC circuit board and a human-computer interaction interface matched therewith. The human-computer interaction interface is generally a touch screen and buttons. Through the touch screen and buttons, the power supply or actuators such as motors of the device can be controlled through the PLC circuit board, thereby realizing control of the device.

[0030] The upper die 22 is slidably disposed on the base 2 , and a cylinder is disposed between the base 2 and the upper die 22 . The cylinder can drive the upper die 22 to move up and down, thereby driving the movement of the bending knife 24 .

[0031] like Figure 1-2As shown, a positioning mechanism 3 and a supporting mechanism 4 are provided on the base 2 and are located at the front and rear sides of the lower mold 21. When the worker places the metal sheet, the positioning mechanism 3 can be pre-adjusted to align the bending portion on the metal sheet with the position of the bending knife 24, thereby ensuring that the metal sheet is accurately bent; and the supporting mechanism 4 can support the bottom of the metal sheet, so that the worker does not need to expend much effort when controlling and moving the larger metal sheet, thereby reducing the worker's consumption, facilitating the control of the position of the metal sheet, and improving efficiency.

[0032] like Figure 3 As shown, the positioning mechanism 3 includes a moving frame 31 slidably arranged on the base 2, and the moving frame 31 is provided with a through groove 32 arranged along its own length direction, and two sliding seats 34 connected to the moving frame 31 through a slide rail 33 are slidably arranged above the through groove 32, and a screw 35 is rotatably arranged on the moving frame 31, and the screw 35 is threadedly connected to the two sliding seats 34 and the thread directions are opposite. A motor is connected to one end of the screw 35, and the motor is connected to the controller 1. Through a preset value, the motor will control the spacing between the two sliding seats 34 through the screw 35 to make it adapt to the width of the metal sheet, so that the sliding seat 34 is located below the two metal sheets.

[0033] like Figure 4 As shown, a slide groove 341 is provided on the sliding seat 34, the slide groove 341 is connected to the through groove 32 and the slide groove 341 is arranged perpendicular to the through groove 32, a limit block 342 is slidably provided on the slide groove 341 and extends toward the lower mold 21 and is higher than the top surface of the die assembly 23, two limit blocks 342 are slidably provided in the slide groove 341 of the sliding seat 34 and a slider 343 is extended downward into the slide groove 341, and an angle adjustment mechanism connected to the slider 343 is provided between the two limit blocks 342.

[0034] like Figure 5 As shown, the angle adjustment mechanism includes a rotating motor 344 arranged on the movable frame 31 and connected to the controller 1, the driving shaft 345 of the rotating motor 344 extends to the bottom of the limit block 342 and is fixedly connected to an adjusting rod 346, the adjusting rod 346 is provided with a longitudinal groove 347 arranged along its own length direction, the longitudinal groove 347 is slidably connected to the slider 343, and the adjusting rod 346 rotates around the driving shaft 345 of the rotating motor 344 as the center of the circle.

[0035] When the staff needs to process an oblique bend on the metal sheet, the controller 1 can be used to control the rotating motor 344 so that the driving shaft 345 of the rotating motor 344 drives the adjusting rod 346 to rotate a certain angle. Since the two ends of the adjusting rod 346 are slidably connected to the slider 343, the two sliders 343 are located on the same axis as the reference axis. The rotation of the adjusting rod 346 will drive the two sliders 343 to move toward each other along the slide groove 341. At this time, the angle formed between the adjusting rod 346 and the reference axis is the inclination angle between the two sliders 343. At this time, the staff will move the side of the metal sheet to be bent closer to the limit block 342 until one side of the metal sheet abuts against the two limit blocks 342, so that the metal sheet is tilted at a certain angle, so that the bending knife 24 can process an inclined bend on the metal sheet, thereby realizing more bending of different shapes and improving practicality.

[0036] Furthermore, by forming two limit plates at different inclined positions, when bending on some special-shaped metal sheets, it can be ensured that there will be no error in the position of the bending part, thereby improving the performance of the sheet metal parts after processing.

[0037] like Figure 3 As shown, a driving mechanism 5 electrically connected to the controller 1 is arranged between the mobile frame 31 and the base 2, a slide rail 33 is arranged on the base 2, and connecting blocks slidably matched with the slide rail 33 are arranged on both sides of the mobile frame 31. The driving mechanism 5 includes a driving motor 51 fixedly arranged on the base 2, and the output shaft of the driving motor 51 is connected to a screw 35, and the screw 35 is threadedly connected to the mobile frame 31; the driving motor 51 drives the screw 35 to rotate so that the mobile frame 31 can be controlled to slide back and forth relative to the lower mold 21, so that the mobile frame 31 can adjust the distance between the limit block 342 and the lower mold 21 to adapt to bending at different positions.

[0038] like Figure 1 , 6 As shown, a support mechanism 4 is provided on the front side of the base 2, and the support mechanism 4 includes a mechanical arm 41 provided on both sides of the base 2, and the mechanical arm 41 includes a main arm 42 connected to the base 2 through a ball shaft, and a driving arm group 43 is connected to the main arm 42, and the driving arm group 43 is connected through a ball shaft, and a clamping member 44 is connected to the driving arm group 43 through a ball shaft; the driving arm group 43 and the main arm 42 connected through the ball shaft can move in universal directions relative to each other, thereby improving the flexibility of the mechanical arm 41, thereby improving the mobility of the clamping member 44 to realize the movement and clamping of the metal sheet in different angles and directions.

[0039] like Figure 6-7As shown, the clamping member 44 includes a connecting seat 441 which is rotatably arranged at the end of the mechanical arm 41 through a ball shaft, and the connecting seat 441 is provided with two clamping plates 442 which are slidably arranged on one side of the metal sheet, and the two clamping plates 442 are distributed up and down on the connecting seat 441 and a clamping groove 443 is formed therebetween, and a driving spring 444 is provided between the clamping plates 442 and the connecting seat 441 for driving the clamping plates 442 to slide relative to the clamping groove 443; the driving spring 444 can ensure that the two clamping plates 442 stably clamp the side wall of the metal sheet, thereby preventing the metal sheet from detaching from the clamping member 44.

[0040] A mounting groove 445 is provided on one side of the clamping plate 442 opposite to the clamping groove 443, and at least two conveying rollers 446 are rotatably arranged in the mounting groove 445. The two conveying rollers 446 are connected to each other through a belt 447, and one of the conveying rollers 446 is connected to a micro motor 448, and the micro motor 448 is connected to a controller 1. A push switch 449 for controlling the micro motor 448 is also provided on the robot arm 41; wherein the two micro motors 448 located on the same connecting seat 441 can be controlled to open and close by a push switch 449, and the two micro motors 448 control the conveying rollers 446 on one of the clamping plates 442 respectively.

[0041] When the staff needs to clamp the metal sheet, the staff can manually control the two robotic arms 41 to first locate them on the two side edges of the metal sheet, and then place the two side edges of the metal sheet in the clamping grooves 443 formed by the two clamping plates 442, so that the two sets of conveying rollers 446 clamp the two side edges of the metal sheet to stabilize it, thereby providing auxiliary support for the metal sheet, thereby reducing the force borne by the staff in supporting the metal sheet, thereby making it easier for the staff to work. When the staff needs to move the direction or position of the metal sheet, the two robotic arms 41 will move accordingly when the staff controls the position of the metal sheet. Because the connection between the robotic arms 41 is a ball-axle connection, it can be moved and adjusted in all directions, making it more convenient to adjust the movement position of the metal sheet. In the process of bending the metal sheet, since the two sides of the metal sheet will curl upward along the bend, the robotic arm 41 will also move accordingly.

[0042] The conveying roller 446 arranged in the mounting groove 445 of the clamping plate 442 can start the micro motor 448 when the staff presses two push switches 449 respectively, so that the conveying roller 446 rotates to drive the metal sheet to move toward the limit block 342. The push switch 449 can also be set under the base 2 as a foot-operated type, so that the staff can control and adjust the position of the metal sheet with both hands, and then use their feet to start the micro motor 448 to move the metal sheet forward. During this process, the staff does not need to approach the bending knife 24, thereby avoiding the possibility of the equipment causing harm to the staff during the bending process, thereby improving the safety of the equipment during use.

[0043] like Figure 8 As shown, the base 2 is also provided with a rotating bracket 6 located between a pair of mechanical arms 41, and the rotating bracket 6 includes a support rod 61 fixedly connected to the base 2, and a rotating shaft 62 is rotatably provided at the end of the support rod 61, and a mounting plate 63 is fixedly provided on the rotating shaft 62, and a supporting turntable 64 is rotatably connected to the mounting plate 63; by arranging the supporting turntable 64 on the base 2, the top surface of the supporting turntable 64 is flush with the top surface of the die assembly 23, thereby also supporting the bottom surface of the metal sheet, further saving the physical strength of the staff, and at the same time, the supporting thin plate cooperates with the mechanical arm 41 to disperse the weight of the metal sheet, ensure the stability of the mechanical arm 41 when clamping the metal sheet, so that the mechanical arm 41 mainly plays a role in supporting the side of the metal sheet during the processing.

[0044] The support turntable 64 can be rotatably set on the mounting plate 63, so that the support turntable 64 can drive the metal sheet to rotate; when the edge of the metal sheet needs to be replaced, the staff can first separate the clamping member 44 from the metal sheet, and then rotate the support turntable 64 to realize the rotation of the metal turntable, so that the staff can easily complete the adjustment of the position of the metal sheet when there is only one person, making the operation more convenient and quick, and improving efficiency; the mounting plate 63 can swing along the support rod 61. When the metal sheet is too large, the staff can use the mounting plate 63 to tilt the metal sheet to move it away from the equipment, thereby avoiding interference and collision between the metal sheet and the equipment during rotation.

[0045] A locking sleeve 65 is also slidably provided at the end of the rotating shaft 62, and a locking rod is provided on the locking sleeve 65. A locking groove 66 which is plugged into and cooperates with the locking rod of the locking sleeve 65 is provided on the support rod 61. The cooperation between the locking sleeve 65 and the locking groove 66 can limit the rotation of the rotating shaft 62, thereby ensuring the stability of the rotating shaft 62 during the processing.

[0046] The support rod 61 is rotatably connected to a support turntable 64, on which an anti-skid pad is arranged. The anti-skid pad is made of rubber with particles on the surface, which can increase the friction between the metal sheet and the metal sheet, thereby preventing the metal sheet from shifting during operation.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
