In the present invention, the working principle and working process of the forming device for cable accessories are as follows:
step 1: initial setting: the rodless cylinder 25 drives the cylinder slide block 252, the slide plate 24, the lower die fixing plate 32 and the lower die 31 to move to the middle position of the workbench 1; the lifting plate 44, the upper die fixing plate 52 and the upper die 51 are driven to move to the highest position by the hydraulic cylinder 43;
step 2: copper aluminum pipe coating: opening the cover closing plate 65, accumulating the copper aluminum tubes 7 from the bottom of the discharging tube 64 until the copper aluminum tubes are accumulated to the top of the discharging box 63, and then closing the cover closing plate 65;
step 3: taking a copper-aluminum pipe: the lower die 31 on the left is driven by the rodless cylinder 25 to move to the position right below the discharging pipe 64, so that the copper-aluminum pipe 7 positioned on the lowest position in the discharging pipe 64 falls into a positioning groove I311 a of the lower die block 311, meanwhile, the lower die 31 on the right moves to the position right below the upper die 51 on the right, and the hydraulic cylinder 43 on the right drives the upper die 51 on the lower die to be air-compressed downwards once and quickly lifted to the highest position;
step 4: copper aluminum pipe feeding: the rodless cylinder 25 drives the left lower die 31 carrying the copper-aluminum pipe 7 to move to the position right below the left upper die 51, the left hydraulic cylinder 43 drives the upper die 51 thereon to press once downwards and rapidly lift to the highest position, and meanwhile, the right lower die moves to the position right below the discharging pipe 64, so that the copper-aluminum pipe 7 positioned at the lowest position in the discharging pipe 64 falls into the positioning groove one 311a of the lower die block 311;
step 5: press-fitting a copper-aluminum pipe: when the hydraulic cylinder 43 in Step4 drives the upper die 51 to move downwards, the upper die is firstly clamped with the inner side end of the copper-aluminum tube 7 through the pressing block 512, then the part of the forming groove 511b of the upper die block 511 is contacted with the outer side end of the copper-aluminum tube 7 and flattened, then the outer side end of the copper-aluminum tube 7 is subjected to fillet cutting through the shearing action between the forming groove 511b and the corner cutting boss 311c, meanwhile, the trigger column 516 is abutted with the sliding column II 313 and pushes the sliding column II 313 to move downwards, the sliding column II 313 moves downwards to push the sliding column I312 to move outwards, the sliding column I312 moves outwards to push the sliding column III 314 to move upwards, the sliding column III 314 moves upwards to punch the outer side end of the copper-aluminum tube 7, and the copper-aluminum tube 7 is pressed and formed into a cable connecting nose at one time;
