Description

Technical Field

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. The accessories of the transformer are roughly divided into iron winding, insulation, lead wire, oil tank and shell, among which the door of the shell is mostly formed by cutting and bending. However, the existing equipment still has some defects when cutting and bending the transformer shell: When the existing equipment performs cutting and bending processing on the transformer casing, the operator usually manually places the plate of the transformer casing door on the bending processing table of the bending equipment, which makes the feeding of the transformer casing door in the cutting and bending process inconvenient and has certain safety hazards. The operator's hands are often injured due to operating errors. At the same time, after a bending process, it is necessary to manually take it out, manually change the side, and then bend the other sides, which makes the cutting and bending process of the transformer casing door inconvenient and causes low efficiency of the cutting and bending process of the transformer casing door. When cutting and bending the transformer casing, the existing equipment mostly uses grinding equipment to grind the outer corners of the outer edges of the transformer casing door to make the outer corners into arc angles for subsequent assembly.

[0041] Working principle: When it is necessary to produce the transformer housing door, the operator first places the transformer housing door embryo plate on the cutting table 21, and cuts the transformer housing door embryo plate on the cutting table 21 into the required size by adjusting the position of the X-axis and Y-axis of the laser cutting device 23, and performs seven-shaped cutting on the four corners of the transformer housing door embryo plate for subsequent bending processing (this is a mature technology in the prior art and will not be described in detail here). After the cutting is completed, the operator turns on the second motor 92, and the driving shaft of the second motor 92 rotates the corresponding second rotating shaft 81. At this time, the second rotating shaft 81 rotates synchronously in the same direction through the two second synchronous wheels 89 and the second synchronous belt 9, and the third transmission rod 88 rotates in the same direction through the two second gears 91. The second rotating shafts 81 rotate synchronously in the opposite direction. At this time, the four second rotating shafts 81 make the two second transmission belts 83 in a synchronous reverse transmission state through the four second transmission wheels 82. The two second transmission belts 83 make the multiple limit blocks 85 and the two push blocks 87 move on the second transmission belts 83 through the multiple third moving rods 84 and the two fourth moving rods 86. The ends of the multiple limit blocks 85 limit the two sides of the transformer housing door embryo plate. The two push blocks 87 turn over and move horizontally. The side edges thereof contact the ends of the transformer housing door embryo plate and push the transformer housing door embryo plate to move horizontally toward one side of the bending table 31. When the transformer housing door embryo plate is pushed to the upper surface of the lower template 33 and the transformer housing door embryo plate is aligned with the four sides of the lower template 33, the second motor 92 is turned off. At this time, the operator turns on the first motor 4, and the driving shaft of the first motor 4 rotates the rotating disk 42 through the rotating rod 41. The rotating disk 42 makes the U-shaped frame 35 and the return-shaped pressing plate 36 drop vertically through the driving rod 43 and the push-pull rod 44. As the return-shaped pressing plate 36 drops vertically, the lower surface of the return-shaped pressing plate 36 contacts the upper surface of the transformer housing door embryo plate. In the process of continuing to drop, in cooperation with the action of the lower template 33, the downward pressure of the return-shaped pressing plate 36 bends the transformer housing door embryo plate into the transformer housing door, thereby conveniently realizing the automatic bending process of the transformer housing door during the cutting and bending process, so that the transformer housing door is formed in one piece, without manual side-changing bending, thereby improving the efficiency of the cutting and bending process of the transformer housing door; After the transformer casing door embryo plate is bent on the bending table 31 to form the transformer casing door, the operator starts the second motor 92 and the grinder body 61 at the same time, and the two push blocks 87 continue to move horizontally to push the transformer casing door toward one side of the edge grinding table 51. When the transformer casing door is pushed to the upper surface of the edge grinding table 51, during this process, the two sides of the transformer casing door contact the opposite sides of the two elastic pressing strips 53. The two elastic pressing strips 53 limit the transformer casing door on the edge grinding table 51 through their own elastic potential energy. The edge of the upper end surface of the transformer casing door contacts the grinding wheel of the grinder body 61. At the same time, the two push blocks 87 synchronously flip and turn edges in the opposite direction and move horizontally toward one side of the cutting table 21. At this time, multiple teeth 93 gradually align with a corresponding first gear. 682 meshes, at this time, the two first first gears 682 rotate the second transmission rod 681, and the second transmission rod 681 rotates the corresponding first rotating shaft 56 through the two first synchronous wheels 69 and the first synchronous belt 691. At this time, the four first rotating shafts 56 transmit the first transmission belt 58 through the four first transmission wheels 57, and the first transmission belt 58 moves the grinder body 61 around through the first moving rod 59 and the mounting sleeve 6. During the process of moving around, the grinder body 61 grinds the edge of the upper end face of the transformer housing door, and grinds the positive angles around the upper end face of the transformer housing door into arc angles, thereby conveniently realizing the grinding process in the cutting and bending process of the transformer housing door, simplifying the processing procedure of the transformer housing door, and thus improving the processing efficiency of the transformer housing door; During this process, the feeding operation is performed by two pushing blocks 87 to feed the transformer casing door blank onto the bending table 31, and the transformer casing door on the bending table 31 is fed onto the edge grinding table 51. When the edge grinding process is completed, the next transformer casing door (not edged) pushes the transformer casing door on the edge grinding table 51 during the movement, and the transformer casing door on the edge grinding table 51 enters the storage box 71 through the feeding trough 72, and automatically falls to the bottom of the storage box 71 by its own gravity, thereby conveniently realizing the automatic feeding of the transformer casing door during the cutting process, reducing the operation time of manual feeding, improving the efficiency of the cutting and bending process of the transformer casing door, and reducing the risks existing in the cutting and bending process of the transformer casing door, thereby avoiding hand injuries of the operator.
