[0006] The production apparatus for producing the arc-shaped cover plate includes: a base with two grooves on the top, one end of each groove extending to one side of the base, a first blade groove on one side of each groove, a movable chamber inside the base, and a movable groove at the bottom of the movable chamber; a movable tool holder disposed inside the movable chamber, including a lead screw, a movable block, a rotating arm, a cutting tool, and a gear, the lead screw passing through and driving the movable block, the movable block sliding within the movable groove, both ends of the movable block being rotatably connected to the rotating arm, the other end of the rotating arm being connected to the cutting tool, at least a portion of the cutting tool being slidably disposed within the first blade groove, and one end of the lead screw extending out of the base being mounted on the axis of the gear; and a bending device for bending both ends of an unformed workpiece, including a bracket, a first push rod, a bending frame, and a spring fixing component, the first push rod being fixed... A bending frame is fixedly mounted on the support and drives the bending frame. Bending blocks that mate with the sliding groove are installed at both ends of the bending frame. A spring fixing member is installed at the bottom of the bending frame to press the workpiece tightly and prevent loosening. A rack is installed on one side of the bending frame, meshing with the gear to drive the lead screw to rotate and make the movable block slide within the movable groove. A transport device includes two rollers and a roller seat. The lower roller is shorter than the upper roller, and its two ends have grooves that mate with the sliding groove. It is located on one side of the base. A pressing frame is used to perform arc processing on the unformed workpiece after bending. It includes a second push rod, a pressing rod, and a pressing seat. The second push rod is installed on one side of the base, and the pressing rod is slidably mounted on the pressing seat. The second push rod is connected to one end of the pressing rod to drive the pressing rod to move up and down.

[0007] In some embodiments, the cutting tool includes a plurality of blades and a cutting plate, wherein the blades are triangular and the plurality of blades are arranged in an array and mounted on one side of the cutting plate.

[0008] In some embodiments, a limiting post is provided inside the movable compartment to restrict the movement of the movable tool holder.

[0009] In some embodiments, the bottom of the spring retainer is at a lower level than the bottom of the bent block.

[0010] In some embodiments, an auxiliary roller is disposed above the base.

[0011] In some embodiments, a plurality of second blade grooves that cooperate with the blade are provided on one side of the bottom of the bending block, while the opposite side of the bending block is rounded.

[0012] A manufacturing process for an arc-shaped cover plate is used: S1: Transport the sheet metal to the top of the base using a conveyor device; S2: The first push rod drives the bending frame to begin descending. At the same time as it descends, the blade is driven to slide outward. The bending block bends both ends of the sheet metal and completes the cut. S3: The first push rod drives the bending frame to start rising. At the same time as rising, the blade is driven to be stored in the first blade slot. The transport device transfers the sheet material that has been cut and bent to the bottom of the arc pressing frame. S4: The second push rod begins to descend, and the plate that has completed the cutting and bending is subjected to curvature processing by the pressure rod; S5: Cut the sheet material that has been cut, bent and curved, and complete the support frame manufacturing process. Then process the remaining sheet material that has been curved and assemble it with the support frame to complete the arc cover plate assembly.

[0013] The beneficial effects of this application are as follows: when bending unprocessed sheet metal, the gear can be driven to rotate, thereby causing the movable block to move back and forth. During the movement of the movable block, the rotation on both sides will drive the blade to slide, so that the blade will slide out synchronously when the first push rod descends, so that the sheet metal can be bent and cut synchronously. When the first push rod rises, the blade will retract synchronously, so that the sheet metal that has completed bending and cutting can slide in the groove. Attached Figure Description

[0023] Reference Figure 1-2 As shown, this application provides an arc-shaped cover plate 1, comprising: a cover plate 11, which is generally arc-shaped; a cover plate frame 12, which fits the arc shape of the cover plate 11 and is fixedly disposed at both ends on the inner side of the cover plate 11; a support frame 13, which is generally L-shaped and forms a first panel 131 and a second panel 132, wherein the first panel 131 is arc-shaped and the second panel 132 has a plurality of cuts 1321, and its outer contour is arc-shaped; and a support plate 14, which fits the arc shape of the support frame 13, and one side of the support plate is fitted and fixed to the first panel 131.

[0024] In the embodiments of this application, please refer to Figure 3-6As shown, this application provides a production device and process for an arc-shaped cover plate, mainly including: a base 2, with two sliding grooves 21 on the top, one end of each sliding groove 21 extending to one side of the base 2, and a first blade groove 22 on one side of each sliding groove 21; a movable chamber 23 is provided inside the base 2, and a movable groove 231 is provided at the bottom of the movable chamber 23; a movable blade holder 3, disposed inside the movable chamber 23, including a lead screw 31, a movable block 32, a rotating arm 33, a blade 34, and a gear 35, wherein the lead screw 31 passes through and drives the blade 34. Movable block 32 slides within the movable groove 231. Both ends of the movable block 32 are rotatably connected to the rotating arm 33, and the other end of the rotating arm 33 is connected to the cutter 34. At least a portion of the cutter 34 is slidably disposed within the first blade groove 22. One end of the lead screw 31 extending out of the base 2 is mounted on the axis of the gear 35. Bending device 4, used for bending both ends of an unformed workpiece, includes a bracket 41, a first push rod 42, a bending frame 43, and a spring fixing member 44. A push rod 42 is fixedly mounted on the bracket 41 and drives the bending frame 43. Bending blocks 431 that mate with the slide groove 21 are installed at both ends of the bending frame 43. A spring fixing member 44 is installed at the bottom of the bending frame 43 to press the workpiece tightly and prevent loosening. A rack 432 is installed on one side of the bending frame 43. The rack 432 meshes with the gear 35 to drive the lead screw 31 to rotate and cause the movable block 32 to slide within the movable groove 231. The conveying device 5 includes two rollers 51 and one roller... The base 52 has a lower roller 51 that is shorter than the upper roller 51, and its two ends are provided with grooves 53 that cooperate with the sliding groove 21. It is located on one side of the base 2. The arc pressing frame 6 is used to perform arc processing on the unformed workpiece after bending. It includes 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 disposed on the arc pressing seat 63. 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 via the transport device 5, the first push rod 42 drives the bending frame 43 to descend. Firstly, the spring fixing member 44 secures the four corners of the unformed workpiece to prevent it from loosening during bending and thus ensuring poor bending quality. The descent of the bending frame 43 causes the rack 432 to move downwards, which in turn drives the gear 35, which in turn drives the lead screw 31. Under the rotation of the lead screw 31, the movable block 32 moves within the movable groove 231. The rotating arms 33, which rotate at both ends of the movable block 32, drive the cutter 34 outwards under the action of the movable block 32, causing the blade 341 to appear within the slide groove 21. During the bending of the unformed workpiece, the blade 341 completes the multiple cuts 121 on the second panel 132. Subsequently... The bending frame 43 rises, and the rack 432 drives the gear 35 to rotate in the opposite direction, causing the slider to return to its original position. At the same time, the cutter 34 is retracted into the first blade groove 22. The unformed workpiece that has completed bending and cutting 121 loses the restriction of the blade 341 and can slide freely in the groove 21. Because the transport device 5 is provided with a groove 53, the workpiece can slide in the transport device 5 without interfering with the bent second panel 132. The arc pressing frame 6 provided between the two transport devices 5 can be driven by the second push rod 61 to manufacture the curvature of each part of the arc cover plate 1 when the transport device 5 transports the unformed workpiece that has completed bending and cutting 1321 out. Finally, the two ends of the transported workpiece are cut to complete the processing of the support frame 13. The remaining plate material is used for the rest of the arc cover plate 1.

[0026] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

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

[0028] Preferably, in order to prevent the cutter plate 342 from disengaging from the movable arm at a predetermined stroke, a limiting post 232 is provided in the movable compartment 23 to restrict the movement of the movable cutter holder 3.

[0029] Preferably, the bottom of the spring fixing member 44 is lower than the bottom of the bending block 431. With this configuration, when the bending frame 43 descends, the spring fixing member 44 first provides initial fixation to the unformed workpiece, and then further presses and fixes it as the bending frame 43 continues to descend, preventing the unformed workpiece from warping due to strong forces at both ends.

[0030] Preferably, in order to allow the unformed workpiece to enter or leave 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 that cooperate with the blade 341 are provided on one side of the bottom of the bending block 431. At the same time, the opposite side of the bending block 431 is rounded. The presence of the second blade grooves 4311 allows the bending block 431 to enter the slide groove 21 without interfering with the blade 341 when it is fully descending. The rounded treatment on one side of the bending block 431 ensures that when the bending block 431 is bending, it first contacts the outermost two ends of the unformed workpiece. Under the lever action, the first push rod 42 requires less force, thus reducing power consumption.

[0032] Reference Figure 5 The manufacturing process of an arc-shaped cover plate is shown below, and the steps are as follows: S1: The sheet metal is transported to the top of the base 2 via the transport device 5; S2: The first push rod 42 drives the bending frame 43 to begin to descend. At the same time as it descends, it drives the blade 341 to slide outward. The bending block 431 bends both ends of the sheet and completes the cut 121. S3: The first push rod 42 drives the bending frame 43 to start rising. At the same time as rising, the blade 341 is driven to be stored in the first blade groove 22. The transport device 5 transfers the sheet material with the cut 121 and bending to the lower part of the arc pressing frame 6. S4: The second push rod 61 begins to descend, and the plate with the cut 121 and bend is subjected to curvature treatment by the arc pressing rod 62; S5: Cut the sheet material with cut 121 and bending and curvature treatment to complete the support frame 1 manufacturing process. After processing the remaining sheet material with curvature treatment, assemble it with the support frame 1 to complete the arc cover plate assembly.
