[0002] The bus duct is a closed metal device composed of copper and aluminum busbars. The shell of the existing bus duct is usually formed by stamping.

[0003] In the prior art, the manufacture of the bus duct shell is generally performed by stamping and forming through a bus duct shell stamping die. The bus duct shell stamping die is usually divided into an upper die and a lower die. The stamping material is placed in the lower die and then formed by pressing the upper die downward. In this process, in order to ensure the accuracy of the stamping, the lower die is usually fixed below the upper die, which makes it difficult to quickly disassemble and replace the lower die after a long period of use, reducing the flexibility of the lower die disassembly and assembly. At the same time, after the stamping material is formed, the material is usually cut manually, but because the stamping will generate high temperature, the formed shell also has a high temperature phenomenon, resulting in manual failure to cut the material in time, reducing the efficiency of cutting the bus duct shell, and thus reducing the efficiency of the overall processing of the bus duct.

[0022] The positioning mechanism 300 is located in the processing table 100 and is used to position the lower mold. The positioning mechanism 300 includes a positioning tube 301 and a sealing plug 302. The positioning tube 301 and the sealing plug 302 are located in the longitudinal slot opened in the processing table 100 and below the lower mold. The top of the positioning tube 301 is a suction cup structure and contacts the lower surface of the second lower mold 205. The sealing plug 302 is located on one side of the positioning tube 301. The sealing plug 302 is arranged on a support plate 303. The bottom of the support plate 303 is connected with a fastening rope 304. The fastening rope 304 is led out of the processing table 100 and connected to a reel frame 306 arranged on one side of the processing table 100. A transverse long hole is connected to the bottom of the longitudinal slot of the processing table 100. A guide rod 305 is provided at the connection between the bottom of the longitudinal slot and the long hole. The fastening rope 304 leads from the bottom of the longitudinal slot to the long hole under the action of the guide rod 305 and then connects to the reel frame 306 located at the exit of the long hole.

[0023] The reset mechanism 400 is located in the processing table 100 and is used to reset the lower mold; the reset mechanism 400 includes a telescopic rod 401, the telescopic rod 401 is connected to the bottom of the support plate 303, and a first spring 402 is arranged at the connection between the telescopic rod 401 and the support plate 303, and the other end of the telescopic rod 401 is connected to a movable support plate 403, and the movable support plate 403 is located in a movable groove 404 arranged inside the processing table 100; a driving motor 410 is arranged inside the processing table 100, and the driving motor 410 is powered by an external power supply. The output end of the driving motor 410 is connected to a connecting block 407, and the connecting block 407 is connected to a driving rod 405, and the driving rod 405 is connected to the other end of the movable support plate 403. The inner wall of the movable support plate 403 is fixed by an insertion rod 406, and a threaded groove is provided on the outer wall of the driving rod 405. The insertion rod 406 can move along the threaded groove on the outer wall of the driving rod 405, thereby causing the driving rod 405 to rotate. A beveled tooth 408 is fixedly provided on the outer wall of the bottom end of the driving rod 405, and a beveled groove 409 is provided outside the beveled tooth 408. The beveled tooth 408 can rotate clockwise along the inner cavity of the beveled groove 409. The beveled tooth 408 and the beveled groove 409 are inclined relative to the driving rod 405. The beveled tooth 408 rotates counterclockwise and descends to produce compression with the beveled groove 409, thereby driving the connecting block 407 to rotate. Otherwise, the connecting block 407 will not be driven to rotate.

[0024] The lifting mechanism 500 is located in the processing table 100 and is used to provide a lifting force to the lower mold. The lifting mechanism 500 includes a mounting rod 501, a lifting rod 502 and a second spring 503.

The lifting mechanism 500 is located below the lower mold, and the lifting rod 502 contacts the lower surface of the lower mold. The sealing plug 302 is located below the lifting mechanism 500.

[0025] A bus duct punching method comprises the following steps: Step 1, when the bus duct needs to be stamped, first fit the second lower mold 205 with the first lower mold 204 to form a complete lower mold. The detachable setting of the first lower mold 204 and the second lower mold 205 allows the lower mold to be replaced as a single unit, so that multiple second lower molds 205 can be set for flexible replacement and use, reducing the use cost of the lower mold.

[0026] Step 2, after the first lower mold 204 and the second lower mold 205 are fully assembled, rotate the reel frame 306. In actual use, one end of the reel frame 306 is connected to the driving member as the driving source of the reel frame 306. The reel frame 306 rotates and drives the tightening rope 304 to be wound, so that the bottom end of the support plate 303 connected to the tightening rope 304 is subjected to a tensile force, which causes the support plate 303 to drive the sealing plug 302 to descend. The top end of the positioning tube 301 is trumpet-shaped and is made of elastic plastic. With the descent of the sealing plug 302, it will generate a downward adsorption force on the second lower mold 205, thereby strengthening the stability of the position of the second lower mold 205 and improving the stamping effect.

[0027] In step 3, the support plate 303 descends and drives the telescopic rod 401 to contract, and the first spring 402 is compressed, and the movable support plate 403 also moves downward along the movable groove 404. When the movable support plate 403 moves downward, it will descend along the outer wall of the driving rod 405, so that the inserted rod 406 fixed on the inner wall of the movable support plate 403 will move along the threaded groove provided on the outer wall of the driving rod 405, and then the driving rod 405 will be rotated, so that the beveled tooth 408 fixed on the outer wall of the bottom end of the driving rod 405 will rotate clockwise along the inner cavity of the beveled groove 409. Due to the limitation of the inclination direction of the beveled tooth 408 and the beveled groove 409, the beveled tooth 408 rotates counterclockwise and descends to squeeze the beveled groove 409, thereby driving the connecting block 407 to rotate, and vice versa. The connecting block 407 is not driven to rotate, thereby fixing the position of the second lower mold 205, thereby achieving the purpose of resetting the lower mold.

[0028] Step 4, after the stamping is completed, the reel frame 306 is rotated in the opposite direction to relax the force of the fastening rope 304 on the support plate 303, so that the first spring 402 generates an upward elastic supporting force on the support plate 303, which can make the top of the sealing plug 302 squeeze and contact with the bottom of the lifting rod 502, and then start the driving motor 410, so that the driving motor 410 drives the connecting block 407 to rotate in the clockwise direction, so that the inclined groove 409 rotates and drives the inclined block 408 to rotate, so that the driving rod 405 rotates, and the driving rod 405 rotates and the movable support plate 403 rotates on the insertion rod 4 06 and the spiral groove to move up, and in the process of moving up, the telescopic rod 401 is driven to move up synchronously, so that with the help of the sealing plug 302 to squeeze the lifting rod 502, the lifting force can be applied to the second lower mold 205 more quickly, so that the bus duct after stamping can be quickly cut. In the above, with the cooperation of the positioning mechanism 300, the reset mechanism 400 and the lifting mechanism 500, the position of the lower mold can be fixed, and convenience is provided for cutting after stamping, which effectively improves the flexibility of disassembly and assembly of the lower mold, thereby enhancing the efficiency of stamping and cutting of the bus duct.

[0029] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
