s1, connecting the upper die carrier 1 to a punch of a stamping die; the plate 30 is flatly placed on the top surface formed by the first stretching male die 11 and the second stretching male die 10 as shown in figures 3-4;
s2, clamping the sheet, operating the stamping die to enable a punch of the stamping die to move downwards, driving the punch to an upper die carrier 1 to move downwards, driving a fixing plate 2, a limiting plate 3, a discharging plate 4 and a blank holder 5 to move downwards synchronously by the upper die carrier 1, pressing the outer edge of the sheet 30 between the top surface of a drawing female die 16 and the blank holder 5 by the blank holder 5, and keeping the whole discharging plate 4 and the blank holder 5 still at the moment;
s3, forming a first step, wherein an upper die frame 1, a fixed plate 2 and a limit plate 3 synchronously move downwards along with the continuous downward movement of a punch, the fixed plate 2 moves downwards relative to a discharging plate 4 along a force transfer column 8, the fixed plate 2 drives a first stretching male die 11 and a third stretching male die 12 to synchronously move downwards, meanwhile, a nitrogen spring 7 in the upper die frame 1 drives a second stretching male die 10 to synchronously move downwards, after the first stretching male die 11, the second stretching male die 10 and the third stretching male die 12 move for a certain distance, the lower end parts of the first stretching male die 11, the second stretching male die 10 and the third stretching male die 12 simultaneously penetrate out of a blank holder 5, after the first stretching male die 11 and the first female die floating block 20 clamp the plate part between the first stretching male die 11 and the second female die floating block and stretch downwards, meanwhile, the third stretching male die 12 and the third female die floating block 21 clamp the plate part between the first stretching male die 12 and stretch downwards, and simultaneously, the second stretching male die 10 downwards extrudes the plate part under the elasticity of the nitrogen spring 7, when the second stretching male die 10 presses the plate between the second stretching male die 10 and the second female die floating block 22, a semi-finished product 31 with a first step 27 can be stretched out as shown in fig. 5-7;
s4, forming a second step, wherein with the continuous downward movement of the punch, the fixing plate 2 moves downward relative to the discharging plate 4 along the force transfer column 8, the fixing plate 2 drives the first stretching male die 11 and the third stretching male die 12 to move downward synchronously, because the second stretching male die 10 is limited by the second female die floating block 22, the second stretching male die 10 compresses the nitrogen spring 7 upward, the first stretching male die 11 and the second female die floating block 22 clamp the plate part between the first stretching male die 11 and the second female die floating block 22 and stretch downward, after the die is closed, the second step 28 is stretched out on the basis of the first step 27, meanwhile, the third stretching male die 12 and the third female die floating block 21 clamp the plate part between the first stretching male die 11 and the second female die floating block 21 and stretch downward, and after the die is closed, the third step 29 is stretched out on the basis of the first step 27, so that the finished multi-step electronic product 32 is processed as shown in FIGS. 8-9;
s5, after the processing is finished, operating the stamping die to enable the punch to move upwards, the punch drives the upper die carrier 1 to move upwards, the upper die carrier 1 drives the fixed plate 2 and the limiting plate 3 to move upwards synchronously, the fixed plate 2 moves upwards relative to the discharging plate 4 along the force transmission column 8, the first stretching male die 11, the second stretching male die 10 and the third stretching male die 12 are driven to move upwards synchronously, the punch drives the upper die carrier 1 to move upwards along with the continuous upward movement of the punch, the upper die carrier 1 drives the discharging plate 4 to move upwards through the force transmission column 8, after the blank holder 5 on the discharging plate 4 is separated from the edge of the finished multi-step electronic product, the lower spring 17 drives the ejector rod 18 to move upwards under the restoring force of the lower spring 17, the ejector rod 18 drives the movable plate 19 to move upwards relative to the second die floating block 22, the movable plate 19 drives the second die floating block 22 and the third die floating block 21 to move upwards synchronously, the second concave die floating block 22 and the third concave die floating block 21 jack up the finished multi-step electronic product 32 from the concave cavity of the stretching concave die 16, and at the moment, a worker can take away the finished multi-step electronic product 32, so that the finished multi-step electronic product 32 is finally processed.
Therefore, the drawing forming die can form the first step 27, the second step 28 and the third step 29 at one time only by clamping the plate at one time, and compared with the traditional method of clamping three plates by using three pairs of dies respectively, the drawing forming die not only reduces the times of clamping the plate, but also reduces errors caused by multiple times of clamping, greatly improves the processing precision of multi-step products, and simultaneously improves the production efficiency of the multi-step products. In addition, one pair of dies is adopted to replace three pairs of dies, so that the die cost is greatly saved.
