[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0022] As Figures 1 to 7 shown, a continuous blanking die includes an upper die 1 and a lower die 2. The upper die 1 includes an upper die base 1a, an upper backing plate 1b, a male clamping plate 1c, a stop plate 1d, and a stripper plate 1e arranged in sequence from top to bottom. A cavity penetrating up and down is provided in the male clamping plate 1c, the stop plate 1d, and the stripper plate 1e, and a punch core 1f is provided therein; the lower die 2 includes a lower support plate 2a, a lower pad 2b, a lower die base 2c, a lower backing plate 2d, and a lower template 2e arranged in sequence from bottom to top. A cavity penetrating up and down is provided in the lower template 2e, and a die core 2f is provided therein. A waste slide 2g is provided in the lower pad 2b, and a waste passage 2h leading above the waste slide 2g is provided below the die core 2f;

[0023] An extended material supporting and positioning plate 2i is arranged beside the lower template 2e, and their upper surfaces are flush. A material ejecting block 2e-1 that can move up and down is provided in the lower template 2e, and a material ejecting pin 2i-1 that can move up and down is provided in the extended material supporting and positioning plate 2i. Springs are connected below both the material ejecting block 2e-1 and the material ejecting pin 2i-1, and the workpiece can be jacked up by the elastic force of the springs; A positioning pin 2i-2 protruding from its upper surface is provided on the extended material supporting and positioning plate 2i. The positioning pin 2i-2 is used for positioning the forward feeding movement of the coil strip, and its layout matches the edge where the workpiece blanking is completed.

[0024] Two side retaining edges 1f-1 are provided on the lower surface of the punch core 1f. The distance between the two side retaining edges 1f-1 is greater than the width of the coil strip, and the two side retaining edges 1f-1 limit the left and right offset of the coil strip.

[0025] Waste channels 2h are provided in both the lower die base 2c and the lower backing plate 2d. The cross-sectional area of the waste channel 2h in the lower die base 2c is larger than the cross-sectional area of the waste channel 2h in the lower backing plate 2d. The waste generated by blanking the coil strip can smoothly fall from the lower backing plate 2d to the lower die base 2c. The blanking waste passing through the waste channel 2h will fall on the waste slide 2g and then slide down along its inclined surface for collection.

[0026] A guiding mechanism is provided between the upper die 1 and the lower die 2. The guiding mechanism includes a guide post and a guide sleeve. The guide post and guide sleeve play a crucial role in the blanking die. They ensure the stability and precision of the die by guiding the movement of the punch, supporting and positioning, reducing friction and wear, etc., providing a reliable guarantee for blanking production.

[0027] In the use of the present utility model, the upper die base 1a of the upper die 1 is fixed to the up-and-down moving slide of the punching press, the lower support plate 2a of the lower die 2 is fixed to the working table of the punching press, the positions of the upper die 1 and the lower die 2 correspond up and down, a coil material with a width of 140 mm and a thickness of 1.5 mm is used, and the leveled coil material passes between the blanking plate 1e and the lower template 2e. When the blanking process is started, the punching press drives the upper die 1 to move downward, the blanking plate 1e and the lower template 2e clamp the sheet material, the lower surface of the punch core 1f contacts the sheet material, and it continues to move downward to cooperate with the die core 2f to complete the blanking of the metal sheet material. The waste material falls onto the waste slide 2g through the waste channel 2h and is discharged. The finished products after blanking are grabbed by the robotic arm from the lower template 2e and the extended material supporting and positioning plate 2i. The robotic arm has a large movement space, and the extended material supporting and positioning plate 2i is provided with an induction area for the proximity sensor installed on the robotic arm to detect.

[0028] The process disclosed in the present utility model greatly improves the production efficiency. The continuous supply production method using coil materials can significantly reduce the head and tail losses of materials compared with the traditional single-piece blanking method, thereby improving the material utilization rate, reducing the material waste in the production process, and products with precise blanking dimensions are not prone to dark break phenomena at the R-angle part during the deep drawing process; in addition, it also has the advantage that it is convenient for the robotic arm to pick up materials from the mold.
