The other end of the rotating arm 33 is connected to the tool 34. At least a part of the tool 34 is slidably arranged in the first blade groove 22. One end of the screw rod 31 extending out of the base 2 is installed on the axis of the gear 35; the bending device 4 is used to bend the two ends of the unformed workpiece, including a bracket 41, a first push rod 42, a bending frame 43, a spring fixing member 44, and the first A push rod 42 is fixedly arranged on the bracket 41 and drives the bending frame 43. The two ends of the bending frame 43 are equipped with bending blocks 431 that cooperate with the slide groove 21. The spring fixing member 44 is installed at the bottom of the bending frame 43 to press the workpiece to prevent it from loosening. A rack 432 is installed on one side of the bending frame 43. The rack 432 is meshed with the gear 35 to drive the screw rod 31 to rotate and make the movable block 32 slide in the movable groove 231; the transport device 5 includes two rollers 51 and a roller The seat 52, the lower roller 51 is shorter than the upper roller 51, and grooves 53 cooperating with the slide groove 21 are opened at both ends thereof, and are arranged on one side of the base 2; the arc pressing frame 6 is used to make an arc processing on the unformed workpiece that has completed the bending work, including a second push rod 61, an arc pressing rod 62, and an arc pressing seat 63, the second push rod 61 is installed on one side of the base 2, the arc pressing rod 62 is slidably arranged on the arc pressing seat 63, and the second push rod 61 is connected to one end of the arc pressing rod 62 to drive the arc pressing rod 62 to move up and down.

[0025] Specifically, when the unformed workpiece enters the base 2 through the transport device 5, the first push rod 42 drives the bending frame 43 to descend. First, the spring fixing member 44 fixes the four corners of the unformed workpiece to prevent the unformed workpiece from loosening during bending to prevent poor bending quality. The descent of the bending frame 43 causes the rack 432 to move downward, and the rack 432 drives the gear 35 to drive the screw rod 31. Under the rotation of the screw rod 31, the movable block 32 will move in the movable groove 231, and the rotating arms 33 rotatably arranged at both ends of the movable block 32 will drive the tool 34 to move outward under the action of the movable block 32, so that the blade 341 appears in the slide groove 21, and when the unformed workpiece is bent, the blade 341 completes multiple cuts 121 on the second panel 132, and then , the bending frame 43 rises, and the rack 432 drives the gear 35 to rotate in the opposite direction, so that the slider returns to its position, and at the same time, the tool 34 is retracted into the first blade groove 22, and the unformed workpiece that has completed the bending and cutting 121 loses the limit of the blade 341 and can slide freely in the slide groove 21.

[0026] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0027] Reference Figure 3 As shown, the tool 34 includes a plurality of blades 341 and a tool plate 342. The blades 341 are triangular in shape. The plurality of blades 341 are distributed in an array and installed on one side of the tool plate 342. The design of the triangular blade 341 can optimize the force area of ​​the workpiece during bending, reduce the pressure on a single area of ​​the triangular blade 341, and increase the service life of the blade 341.

[0028] Preferably, in order to prevent the tool plate 342 and the movable arm from deviating from a predetermined stroke, a limiting column 232 for limiting the movement of the movable tool holder 3 is provided in the movable bin 23 .

[0029] Preferably, the horizontal height of the bottom of the spring fixing member 44 is lower than the bottom of the bending block 431. In this arrangement, when the bending frame 43 descends, the spring fixing member 44 first performs a preliminary fixation on the unformed workpiece, and then further compresses and fixes it when the bending frame 43 continues to descend, thereby preventing the unformed workpiece from warping in the center due to the strong force applied to both ends.

[0030] Preferably, in order to allow the unformed workpiece to enter or leave the top of the base 2 more smoothly, an auxiliary roller 24 is provided above the base 2 .

[0031] Reference Figure 6 As shown, a plurality of second blade grooves 4311 cooperating with the blade 341 are provided on one side of the bottom of the bending block 431, and at the same time, an opposite side of the bending block 431 is processed with an arc. The existence of the second blade groove 4311 can prevent the bending block 431 from interfering with the blade 341 when it enters the slide groove 21 and is fully lowered. The arc treatment on one side of the bending block 431 allows the bending block 431 to preferentially contact the two outermost ends of the unformed workpiece when bending. Under the action of the lever, the first push rod 42 requires less force, thereby reducing power consumption.

[0032] Reference Figure 5 The production process of a circular arc cover plate shown in the figure has the following steps: S1: transporting the sheet material to the top of the base 2 through the transport device 5; S2: The first push rod 42 drives the bending frame 43 to start to descend, and at the same time drives the blade 341 to slide outward, and the bending block 431 bends the two ends of the sheet material and completes the incision 121; S3: The first push rod 42 drives the bending frame 43 to start rising, and at the same time drives the blade 341 to be stored in the first blade groove 22, and the transport device 5 transfers the sheet material with the cut 121 and the bend to the bottom of the arc pressing frame 6; S4: The second push rod 61 starts to descend, and the plate material with the cut 121 and the bend is subjected to curvature processing by the arc pressing rod 62; S5: Cut the sheet material that has been processed with the incision 121, bending and curvature to complete the manufacturing process of the support frame 1, and process the remaining sheet material that has been processed and assemble the arc cover plate with the support frame 1.
