Description

Technical Field

[0001] The invention belongs to the technical field of transformer bushing production, and in particular relates to a transformer bushing production cutting machine. Background Art

[0002] The transformer bushing is the main insulating device outside the transformer box. The lead wires of the transformer winding must pass through the insulating bushing to insulate the lead wires and between the lead wires and the transformer casing. At the same time, it plays the role of fixing the lead wires. When producing transformer bushings, it is necessary to cut transformer bushings of different lengths according to demand, so a cutting machine is needed.

[0004] When the above device is in use, it can only clamp the transformer bushing in the center, so that the diameter of the transformer bushing that can be cut by the cutting blade can only be smaller than the radius of the cutting blade, thereby limiting the scope of application.

[0058] In this embodiment, bearings are provided on the periphery of the connecting pipe 761 and the transmission cylinder 762, so that the switching component 76 is not affected when the roller 71 rotates; the hydraulic cylinder 5 is a hydraulic cylinder in the prior art, and when it is in operation, the hydraulic oil will be transported to the connecting pipe 761 through a hose, thereby pushing one side of the piston 763, and when the hydraulic cylinder 5 contracts, it will also move the piston 763 and the push rod 764; one end of the push rod 764 is inserted into the inside of the driving disk 765 and has a bearing, so that when the roller 71 rotates with the positioning component 75 and the driving disk 765, it will not be affected.

[0059] Reference Figure 1-Figure 8 In a further embodiment, a hydraulic cylinder 12 is installed above the bracket 11, and the output end of the hydraulic cylinder 12 is connected to the top of the support frame 13. The inner side of the support frame 13 is rotatably connected to a cutting disc 14, and the sensor 15 is located on one side of the cutting disc 14.

[0060] In this embodiment, a motor is installed on one side of the support frame 13 to drive the cutting disc 14 to rotate, thereby cutting the casing.

[0061] The working principle of the present invention is as follows:

[0062] When the transformer bushing needs to be cut, the transformer bushing can be transported between the two pairs of roller mechanisms 7 through an external transport device, and then the driving motor 23 can be operated through the control terminal 4 to rotate the rectangular shaft 26 and the connecting shaft 27, thereby rotating the linkage bevel gear 28 and the driving bevel gear 35 located in the sliding box 34, thereby rotating the slide groove 32 and the double threaded rod 1 25, thereby allowing the two pairs of linkage mechanisms 6 to respectively clamp the transformer bushing with the roller mechanisms 7;

[0063] When the linkage mechanism 6 is clamping with the roller mechanism 7, the sliding block 62 is threadedly connected by the double threaded rod 25, so that the sliding block 62 brings the receiving ear plate 61 and the limit plate 63 closer to each other, and at this time, the plug-in plate 767 is plugged into the limit groove 64 opened on one side of the limit plate 63, so that the roller 71 cannot rotate, and the positioning plate 751 is always on the outside of the roller 71, so as to maintain stability during clamping, and since the upper parts of the connecting box 24 and the receiving box 31 are provided with the sliding groove 32 and the sliding block 62 is slidably connected therein, the driving motor 23 can clamp the two ends of the transformer bushing cutting at the same time during operation, and at this time, the receiving box 31 can still be displaced by the rotation of the threaded rod 22, so as to adjust the cutting of different lengths;

[0064] When the transformer bushing is clamped and positioned, the control terminal 4 controls the hydraulic cylinder 12 to operate so that the support frame 13 moves down with the cutting blade 14 to cut the transformer bushing. During this process, if the sensor 15 contacts the cut transformer bushing, it will be fed back to the control terminal 4, so that the hydraulic cylinder 5 can operate so that the liquid inside the hydraulic cylinder 5 will be transported to each connecting pipe 761 through the hose, and then transported to the transmission cylinder 762 by the connecting pipe 761, so that the piston 763 and the push rod 764 are pushed, thereby pushing the drive disk 765 to move. At this time, the block 768 will be separated from the inside of the through groove 753 as the connecting frame 766 moves, and the plug plate 767 will also be separated from the limit. The roller 71 is retracted into the interior of the positioning slot 64 and retracted into the interior of the cavity 74. The retraction of the plug-in plate 767 will allow the roller 71 to rotate, and the disengagement of the stop block 768 will allow the elastic member 754 to pull the plug-in column 752 and the positioning plate 751 to retract into the interior of the cavity 74, so that the surface of the roller 71 is in contact with the transformer bushing. At this time, the control terminal 4 can operate the rotating motor 65 on the outside of one of the receiving ear plates 61 to operate so that the connecting shaft 72 rotates with the roller 71 as a whole, so that the transformer bushing can be rotated. When the diameter of the transformer bushing is larger than the rotation radius of the cutting disc 14, the transformer bushing can still be cut, thereby expanding the scope of application.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
