Description

Technical Field

[0001] This utility model belongs to the technical field of flanging devices, specifically relating to a flanging device for cable tray covers. Background Technology

[0002] Cable trays are widely used in industries such as petroleum, chemical, power, and telecommunications. They are mainly used for laying overhead power cables, control cables, lighting circuits, and telecommunications cables. When using cable trays, they need to be used in conjunction with cover plates. The cover plates can close the top of the cable tray to prevent dust and other debris from entering the interior of the cable tray.

[0003] The cover plate needs to be stamped and flanged during production. The commonly used flanging device uses a moving die and a fixed die to stamp. When different models of cover plates need to be stamped, the fixed die and the moving die need to be replaced, which increases the replacement time. In addition, different fixed dies need to be manufactured to match the moving die, which increases the cost. Utility Model Content

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a cable tray cover plate flanging device includes a base 1 and a mounting groove 2. The mounting groove 2 is located at the top of the base 1. An adjustable-spacing bottom support component 3 is provided inside the mounting groove 2. A mounting frame 4 is fixedly connected to one side of the top of the base 1. A folding mold 5 is fixedly connected to the top of the mounting frame 4. The folding mold 5 is correspondingly arranged with the bottom support component 3.

[0021] According to the above structure, the metal plate is stamped and flanged by the folding mold 5 during use. During the stamping and flanging, the bottom support component 3 supports the metal plate. The width of the bottom support component 3 can be adjusted, thereby supporting cover plates of different widths and improving the practicality of the device.

[0022] like Figure 2-4 As shown, the mounting groove 2 includes symmetrically arranged adjustment grooves 21, both of which are located at the top of the base 1. A sliding groove 22 is provided in the middle of the top of the base 1. The bottom support assembly 3 includes a support plate 31 and a lead screw 32. There are two support plates 31, which are slidably connected to the inside of the two adjustment grooves 21 respectively. The lead screw 32 is rotatably connected to the inside of the sliding groove 22. A symmetrically distributed slider 35 is slidably connected inside the sliding groove 22. The side wall of the lead screw 32 is provided with two threaded portions with opposite thread directions. The two sliders 35 are threadedly connected to the two threaded portions respectively. The side wall of the support plate 31 is symmetrically arranged with through grooves 33. A rotating shaft 34 is provided inside the through grooves 33. A connecting rod 36 is symmetrically rotatably connected to one end of the slider 35. One end of the connecting rod 36 is rotatably connected to the corresponding rotating shaft 34. The inside of the adjustment groove 21 is provided with equally spaced screws 37. The screws 37 pass through the corresponding support plate 31. Two nuts 38 for clamping the support plate 31 are provided on the side wall of the screws 37.

[0023] According to the above structure, during stamping, the metal plate is flanged along one side of the support plate 31. When adjusting the width of the bottom support assembly 3, the screw 32 is rotated by the forward and reverse motor 39, which in turn drives the two sliders 35 to drive in opposite directions. Through the transmission of the connecting rod 36, the two support plates 31 are driven to move closer or further apart, thereby adjusting the width between the two support plates 31. When adjusting the position of the support plate 31, the nut 38 on the screw 37 is loosened. After the adjustment is completed, the nut 38 on the screw 37 is tightened, thereby fixing the position of the support plate 31 and improving the stability of the support plate 31.

[0024] like Figure 2As shown, the folding mold 5 includes two symmetrically arranged hydraulic columns 51 and a moving mold 52. The top of the moving mold 52 is symmetrically fixedly connected to a threaded cylinder 56. The threaded cylinder 56 is internally threadedly connected to a stud 57. The top of the stud 57 is fixedly connected to a pentagonal plate 58. The top of the pentagonal plate 58 is fixedly connected to a connector 59. The connector 59 is rotatably connected to the bottom of the hydraulic column 51. The top of the moving mold 52 is symmetrically arranged with a convex shell 53. The inside of the convex shell 53 is slidably connected to a pressure block 54. The top of the pressure block 54 is fixedly connected to an equidistantly distributed spring 55. The top of the spring 55 is fixedly connected to the top of the inner wall of the convex shell 53.

[0025] According to the above structure, when changing the moving mold 52, the pentagonal plate 58 is rotated by the tool, which in turn drives the stud 57 to rotate, separating it from the threaded cylinder 56, so that the moving mold 52 can be changed. During the stamping and flanging, the hydraulic column 51 extends and drives the moving mold 52 to descend. The pressure block 54 first contacts the metal plate. As the hydraulic column 51 continues to extend, the pressure block 54 presses the metal plate under the elastic force of the spring 55 to prevent the metal plate from tilting.

[0026] The working principle of this utility model is as follows: During use, the metal plate is stamped and flanged using the flanged die 5. During the stamping and flanged process, the bottom support assembly 3 supports the metal plate. The width of the bottom support assembly 3 can be adjusted to support cover plates of different widths, improving the practicality of the device. During the stamping and flanged process, the hydraulic column 51 extends, causing the moving die 52 to descend. The pressure block 54 first contacts the metal plate. As the hydraulic column 51 continues to extend, the pressure block 54 presses the metal plate tightly under the elastic force of the spring 55, preventing the metal plate from tilting. The metal plate is flanged along one side of the support plate 31. When adjusting the width of the bottom support assembly 3, the... The forward and reverse motor 39 drives the lead screw 32 to rotate, which in turn drives the two sliders 35 to drive in opposite directions. Through the transmission of the connecting rod 36, the two support plates 31 are driven to move closer or further apart, thereby adjusting the width between the two support plates 31. When adjusting the position of the support plate 31, the nut 38 on the screw 37 is loosened. After the adjustment is completed, the nut 38 on the screw 37 is tightened to fix the position of the support plate 31 and improve the stability of the support plate 31. When changing the moving mold 52, the pentagonal plate 58 is rotated by a tool, which drives the stud 57 to rotate, separating it from the threaded cylinder 56, so that the moving mold 52 can be changed.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
