Technical Field

[0001] The invention relates to the technical field of processing shells of box-type substations, and in particular to a bending device for processing shells of box-type substations. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a combination of high-voltage switchgear, distribution transformer and low-voltage distribution device; the box structure is generally composed of three parts: base, shell and top cover, with functions such as sun protection, rain protection, dust protection, rust prevention and small animal protection; and the shell of the box-type substation needs to be bent into a wavy shape by a bending device during the processing process to increase its contact area with the external environment, thereby accelerating the heat dissipation efficiency of the electrical equipment inside the box-type substation;

[0003] In the process of bending the shell into a wavy shape by the existing bending device, the bending groove and the trapezoidal pressing block of the bending device are likely to scratch the surface of the shell, affecting the efficiency of processing the shell; at the same time, before the bending operation on the shell is performed, the dust and impurities remaining on the surface are not effectively cleaned, so that when the trapezoidal pressing block presses the shell, the dust and impurities are likely to cause damage to the shell. Summary of the invention

[0039] Working principle: When the present invention is used, first, Figure 1-Figure 3As shown, before the box-type substation shell is bent, the extended end of the pressing cylinder 1 is controlled to shrink from the initial length to the shortest, and the lifting tube 303 moves upward, so that the through hole 306 enters the oil storage tank 305, and the lubricating oil in the oil storage tank 305 enters the lifting tube 303, as shown in FIG. Figure 2 and Figure 5 As shown, it then flows along the two output ends of the U-shaped tube 302 to the top surface of the lower mold base 803. Figure 2 and Figure 4 As shown in FIG. 1 , the extension end of the pressing cylinder 1 contracts, which drives the two connecting frames 3041 to rise, so that the transmission wheel rolls from the L-shaped flip frame 3042, passes through the bottom of the guide plate 3045 and moves to the top thereof, driving the L-shaped flip frame 3042 to rotate until it contacts the lower die seat 803.

At this time, the transmission wheel rolls to the bottom of the guide plate 3045, and the rubber plate 3043 is still in elastic contact with the top edge of the lower die seat 803. The lifting tube 303 moves downward, so that the through hole 306 is located below the oil storage tank 305, avoiding the lubricating oil in the oil storage tank 305 from continuing to flow out and causing waste; Figure 1 , Figure 2 and Figure 5 As shown, when the lubricating oil on the top surface of the lower die base 803 flows into the bending groove 801, the extended end of the control pressing cylinder 1 is extended to the longest. At this time, there is a gap between the trapezoidal pressing block 11 and the bending groove 801, and the trapezoidal pressing block 11 squeezes out the lubricating oil in the bending groove 801, so that the top surface of the lower die base 803, the bending groove 801 and the bottom of the trapezoidal pressing block 11 are evenly coated with lubricating oil, so as to prevent the bending groove 801 and the trapezoidal pressing block 11 of the bending device from easily scratching the surface of the shell during operation, thereby avoiding affecting the processing efficiency of the shell; Figure 1 , Figure 6 and Figure 7As shown, before the shell is conveyed to the top surface of the lower mold base 803, when the shell passes between the first cleaning roller 403 and the second cleaning roller 408, the two rotating frames 407 are controlled by an external driving device to rotate counterclockwise at the same time, so that the second cleaning roller 408 contacts the top surface of the shell. At this time, the first cleaning roller 403 contacts the bottom surface of the shell, and the first cleaning roller 403 and the second cleaning roller 408 are turned on to clean the dust and impurities on the surface of the shell, so as to avoid the dust and impurities remaining on the surface from easily causing damage to the shell when the shell is pressed. At the same time, the two rotating frames 407 rotate counterclockwise to cooperate with the corresponding connecting rods 402, driving the two L-shaped transmission frames 405 to rotate clockwise, and providing support for the shell through the support rollers 406 to avoid the middle of the shell from sinking and falling during the movement of the shell.
