Description

Technical Field

[0001] This utility model belongs to the field of stamping and flanging technology, specifically a stamping die heat insulation cover flanging device. Background Technology

[0002] Flanging refers to the forming method of using a mold to create a straight wall or flange at a certain angle on the flat or curved part of sheet metal. Flanging is a structure formed after sheet metal is processed by a stamping mold. In the process of processing heat insulation covers, sheet metal needs to be folded. After folding is completed, the sheet metal needs to be removed from the mold.

[0003] Meanwhile, the "A Stamping Die Heat Insulation Cover Flanging Device" with the announcement number CN202420056419.8 is disclosed, which "includes a worktable, a lower stamping die is provided on the worktable, a support frame is provided on the worktable, an upper stamping die is provided directly above the lower stamping die, a hydraulic drive component for driving the lower stamping die to move up and down is provided on the support frame, and a clamping assembly for clamping the workpiece on the lower stamping die is provided on the worktable";

[0004] The aforementioned stamping die heat insulation cover flanging device uses gears to drive the clamping plate to rotate at a certain angle during use. The rotating clamping plate contacts and presses the sheet metal part, thereby clamping the sheet metal. However, if the sheet metal is too thick, the surface of the clamping plate will only contact the edge of the sheet metal. If the sheet metal is too thin, the top of the sheet metal will only contact the edge of the clamping plate. Good clamping can only be achieved when the top of the sheet metal and the bottom of the clamping plate are fully in contact. Therefore, it can only fix sheet metal of a specific thickness, and its application range is narrow.

[0005] Therefore, a stamping die heat insulation cover flanging device is proposed to address the above problems. Utility Model Content

[0008] Preferably, the inner walls of the four square frames are provided with guide rods, the surfaces of the four pressure seats are provided with guide holes that slide with the surfaces of the guide rods, and the four buffer springs are respectively sleeved on the outside of the four guide rods.

[0009] By adopting the above technical solution, the stability of the pressure seat during movement is improved, and the buffer spring is prevented from being damaged due to excessive bending.

[0010] Preferably, both of the adjusting components include a bidirectional lead screw, a limiting ring, and a support base. The two bidirectional lead screws are rotatably mounted on the inner walls of the two T-slots via bearings. The contact portions of the two bidirectional lead screws with the four sliders are threadedly connected by lead screw nuts. One end of each of the two bidirectional lead screws passes through the inner wall of the front of the two lifting seats and is provided with a turntable. The two limiting rings are respectively disposed on the surface of the two bidirectional lead screws, and the surface of each of the two limiting rings is provided with a plurality of annularly distributed toothed grooves.

[0011] By adopting the above technical solution, the distance between the two corresponding pressure seats is shortened, which makes it easier to press and fix sheet metal of different widths.

[0012] Preferably, the two support seats are respectively arranged on the front of the lifting seat, and the inner walls of the two support seats are slidably connected with insert plates. Each of the two insert plates has a handle on one side and a limiting block on the other side. Each of the two limiting blocks has a toothed block on one side that engages with the toothed groove.

The two reset springs and the two slide rods are disposed on the inner wall of the groove. One end of each of the two reset springs is connected to the bottom end of the lifting frame. The two reset springs are respectively sleeved on the outside of the two slide rods. One end of each of the two slide rods is connected to the surface of the stamping die. The contact portions of the two slide rods and the lifting frame are slidably connected.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following describes an embodiment of this utility model based on its overall structure.

[0031] like Figures 1 to 5 As shown, this utility model provides a stamping die heat insulation cover flanging device, including a worktable 1. A stamping die 2 and a support 3 are fixedly mounted on the top of the worktable 1. A pressing component 4 is provided on one side of the support 3. The pressing component 4 includes a groove 41, two adjusting components 5 and two resetting components 6. The groove 41 is opened on the surface of the worktable 1. A transmission plate 42 is slidably connected to the inner wall of the groove 41. A pedal is fixedly mounted on the bottom end of the transmission plate 42. A lifting frame 43 is fixedly mounted on the top end of the transmission plate 42. Two lifting seats 44 are fixedly mounted on the surface of the lifting frame 43. T-slots 45 are opened on the bottom end of each of the two lifting seats 44. Two sliders 46 are slidably connected to the inner wall of each of the two T-slots 45. A square frame 47 is fixedly mounted on the bottom end of each of the four sliders 46. A pressure seat 48 is slidably connected to the inner wall of each of the four square frames 47. A buffer spring 49 is fixedly mounted between each of the four pressure seats 48 and the corresponding square frame 47.

[0032] In this embodiment, guide rods 7 are fixedly provided on the inner walls of the four square frames 47, and guide holes that slide with the surfaces of the four pressure seats 48 are provided on their surfaces. The pressure seats 48 will slide along the surfaces of the guide rods 7 through the guide holes. Therefore, the guide rods 7 guide the moving pressure seats 48 and improve their stability during movement. Four buffer springs 49 are respectively sleeved on the outside of the four guide rods 7. The guide rods 7 limit the compressed buffer springs 49 to prevent them from being damaged due to excessive bending.

[0033] In this embodiment, each of the two adjusting components 5 includes a bidirectional lead screw 51, a limiting ring 53, and a support base 54. The two bidirectional lead screws 51 are rotatably mounted on the inner walls of the two T-slots 45 via bearings. The contact parts of the two bidirectional lead screws 51 and the four sliders 46 are all connected by lead screw nuts. Rotating the bidirectional lead screw 51 will drive the two sliders 46 to move closer to each other, shortening the distance between the two sliders 46, so as to shorten the distance between the corresponding two pressure seats 48, which is convenient for pressing and fixing sheet metal of different widths. One end of each of the two bidirectional lead screws 51 passes through the inner wall of the front of the two lifting seats 44 and is fixedly mounted on a turntable 52 to facilitate the rotation of the bidirectional lead screws 51. The two limiting rings 53 are fixedly mounted on the surface of the two bidirectional lead screws 51, and the surface of each limiting ring 53 is provided with several annularly distributed toothed grooves.

[0034] In this embodiment, two support seats 54 are respectively fixedly installed on the front of the lifting seat 44. Insert plates 55 are slidably connected to the inner walls of the two support seats 54. A handle is fixedly provided on one side of each of the two insert plates 55, and a limiting block 56 is fixedly provided on the other side of each of the two insert plates 55. A toothed block that engages with the toothed groove is fixedly provided on one side of each of the two limiting blocks 56. After the limiting block 56 moves horizontally, the toothed block engages with the toothed groove to prevent the limiting ring 53 from rotating, and finally prevent the turntable 52 from rotating, thus consolidating the adjustment effect of the turntable 52. A pressure plate 57 is fixedly provided on the back of each of the two insert plates 55, and a compression spring 58 is fixedly provided between each of the two pressure plates 57 and the corresponding support seat 54.

[0035] In this embodiment, each of the two reset components 6 includes a reset spring 61, a slide rod 62, and a rubber block 63. The two reset springs 61 and the two slide rods 62 are fixedly installed on the inner wall of the groove 41. One end of each of the two reset springs 61 is fixedly connected to the bottom end of the lifting frame 43. The two reset springs 61 are respectively sleeved on the outside of the two slide rods 62. One end of each of the two slide rods 62 is fixedly connected to the surface of the stamping die 2. The contact parts of the two slide rods 62 and the lifting frame 43 are slidably connected. After the pedal is released, the reset spring 61 extends and pushes the lifting frame 43 upward until the rubber block 63 is pressed against the stamping die 2. At this time, the pressing seat 48 is away from the sheet metal after the flange is turned, and the reset of the pressing seat 48 is completed, which is convenient to use. The rubber block 63 can absorb the impact and prevent the lifting frame 43 from directly colliding with the stamping die 2.

[0036] In this embodiment, both rubber blocks 63 are fixedly installed on the inner wall of the bottom end of the lifting frame 43. Two through holes are opened on the surface of both rubber blocks 63 to prevent the rubber blocks 63 from sliding and rubbing against the slide rod 62, thereby reducing the resistance encountered by the lifting frame 43 when it moves. The contact parts of the two rubber blocks 63 and the stamping die 2 are slidably connected.

[0037] In this embodiment, support legs are fixedly provided at the four corners of the bottom of the workbench 1, and a hydraulic cylinder 8 is fixedly provided at the top of the bracket 3. A stamping upper die 9 is fixedly provided at the telescopic end of the hydraulic cylinder 8. The telescopic end of the hydraulic cylinder 8 will extend and push the stamping upper die 9 to the lower end. The stamping upper die 9 and the stamping lower die 2 complete the flanging of the sheet metal.

[0038] The lower stamping die 2, hydraulic cylinder 8, and upper stamping die 9 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0039] Working principle and process of a stamping die heat insulation cover flanging device:

[0040] First, place the sheet metal on the top of the stamping die 2. Step down on the pedal, and the pedal will drive the transmission plate 42 to slide downward. The transmission plate 42 will slide relative to the worktable 1. The transmission plate 42 will drive the four pressing seats 48 to move downward through the lifting frame 43, lifting seat 44, slider 46 and square frame 47, so that the pressing seats 48 are in contact with the top of the sheet metal. Then continue to step down on the pedal, and the four pressing seats 48 will be supported by the sheet metal and slide relative to the square frame 47. The square frame 47 will move downward and compress the buffer spring 49. The deformed buffer spring 49 will apply the elastic force to the pressing seats 48 to press and fix the sheet metal. This method can press and fix sheet metal of various thicknesses, increase the scope of application, and avoid the fixing method of the square frame 47 directly pressing the sheet metal. This method can prevent the sheet metal from being deformed by a huge impact in a short time due to excessive force when the worker steps on the pedal.

[0041] Furthermore, by pulling the insert plate 55 away from the limiting ring 53 using the handle, the insert plate 55 moves the limiting block 56, causing the toothed block on one side of the limiting block 56 to separate from the limiting block 56, thus releasing the fixation of the limiting ring 53 and the bidirectional lead screw 51. Then, by rotating the bidirectional lead screw 51 through the turntable 52, the bidirectional lead screw 51 will drive the two sliders 46 to move closer to each other, shortening the distance between the two sliders 46. The sliders 46 drive the pressure seat 48 to move through the square frame 47 and the guide rod 7, shortening the distance between the two corresponding pressure seats 48, which facilitates the clamping and fixing of sheet metal of different widths, enhancing practicality. After adjusting the turntable 52, the handle is released. At this time, the clamping spring 58 will extend and push the pressure plate 57, the insert plate 55 and the limiting block 56 to move, causing the toothed block to engage with the toothed groove, preventing the limiting ring 53, the bidirectional lead screw 51 and the turntable 52 from rotating, thus consolidating the adjustment effect of the turntable 52.
