Shown in Figure 7 is the forming process flow process of embodiment of the invention aerosol container loam cake, may further comprise the steps:
1) blanking forming;
2) shaping;
3) secondary reshaping;
4) depress heavy recess: form the first type of sinking recess, large 2.0 to 2.5 millimeters than the diameter D of the sinking recess outer wall of final molding of the outer diameters of the first type of sinking recess; Round-corner transition between the outer wall of the first type of sinking recess and the bottom surface, radius of rounding is not less than half of described deflection between the outer wall of the first type of sinking recess and the bottom surface outside face.
5) cut edge;
6) punching;
7) volume circle, flange: comprise, to the downward flange of the outer rim of blank, for the outer rim round edge is prepared;
8) overwhelm cone, round edge: utilize mould inwardly to push the outer wall of sinking recess, the bottom surface by the sinking recess is to the lower end application of force of sinking recess inwall, the bottom of sinking recess inwall shunk form back taper; The inside deflection of the outer wall of sinking recess is 2 to 2.5 millimeters, and the drift angle of the sinking recess inwall back taper that forms is 8 to 12 °; Loam cake outer rim round edge and sinking recess inwall back taper are finished simultaneously.
The structure of embodiment of the invention back taper and round edge forming mould as shown in Figure 5 and Figure 6, back taper and round edge forming mould comprise upper die and lower die, patrix comprises knockout rod 5, upper die shank 6, patrix mounting ring 7 and upper mold core 8; Counterdie comprises die shoe 9, counterdie panel 10, round edge die 11, tightening ring 12, counterdie top board 13 and 4 push rods 14.
The tightening ring 12 of sinking recess is installed in holding in the hole of die shoe 9, the base portion of tightening ring 12 and die shoe 9 hold the hole bearing fit; Tightening ring 12 is in working order the time, and the bead 1201 of its lower end is spacing by the step 901 that die shoe 9 holds the hole; The base portion of counterdie top board 13 is installed in the endoporus of tightening ring 12, with the endoporus bearing fit of tightening ring 12.
Round edge die 11 usefulness counterdie panels 10 are fixed on the upper end of die shoe 9, the external diameter bearing fit of the endoporus of round edge die 11 and tightening ring 12 base portions, the upper end of round edge die 11 endoporus comprises annular groove 1101, and the periphery of annular groove 1101 and tightening ring 12 base portions forms the die of loam cake outer rim round edge.
The diameter of bore of tightening ring 12 upper ends less than sinking recess 102 just type outer walls 104 external diameter, difference is 2 Δs, namely 2 to 2.5 millimeters; The external diameter of upper die annular convex 801 is less than the internal diameter of sinking recess 102 first type outer walls 104, and difference is 2 Δs, namely 2 to 2.5 millimeters.
The edge on counterdie top board 13 tops is inlaid with 4 magnet 15, and the lower end of tightening ring 12 comprises lip, and the lower end of counterdie top board 13 comprises the thrust bead; Counterdie is when the pusher state, counterdie top board 13 is up under the promotion of push rod 14, it is up that the thrust bead of counterdie top board 13 promotes tightening ring 12, the bead 1201 of tightening ring 12 lower ends breaks away from die shoe 9 and holds the step 901 in hole, the lower end of round edge die 11 withstands on the lip of tightening ring 12, and is spacing to tightening ring 12; At this moment, the upper surface of the upper surface of round edge die 11, tightening ring 12 is substantially concordant with the upper surface of counterdie top board 13, and overwhelm cone, the dead work state of round edge operation for punch die this moment.
Manipulator is sent into the blank of loam cake 1 end face of counterdie, and the magnet 15 on counterdie top board 13 tops is adsorbed on the blank of loam cake 1 on the control position.Patrix is descending, and the ring-shaped lug 801 of patrix inserts the sinking recess 102 of loam cake 1, and the counterdie top board 13, the tightening ring 12 that promote loam cake 1 and counterdie are descending simultaneously.When the bead 1201 of tightening ring 12 lower ends is run into die shoe 9 and is held the step 901 in hole, tightening ring 12 stop motions, under the promotion of the ring-shaped lug 801 of patrix, the outer wall 104 of the sinking recess of loam cake 1 enters the endoporus of tightening ring 12.Since the diameter of bore of tightening ring 12 upper ends than sinking recess 102 just type outer walls 104 external diameter, little 2 to 2.5 millimeters, the endoporus of tightening ring 12 upper ends inwardly pushes the outer wall 104 of sinking recess, and the bottom surface 105 by the sinking recess is to the lower end application of force of the inwall 103 of sinking recess, the bottom of sinking recess inwall 103 shunk form back taper; When the inside deflection of the outer wall of sinking recess was 2 to 2.5 millimeters, the drift angle of sinking recess inwall 103 back tapers was 8 to 12 °.
When the ring-shaped lug 801 of patrix propped up the sinking recess 102 of loam cake 1, the lower surface 701 of patrix patrix mounting ring 7 promoted the outer rim 105 of loam cake 1 downwards.After the outer wall 104 of the sinking recess of loam cake 1 enters the endoporus of tightening ring 12, the annular groove 1101 that the lower surface 701 of patrix patrix mounting ring 7 flange 106 that loam cake 1 outer rim is downward pushes round edge die 11 endoporus upper end carries out crimping, and namely the round edge process of loam cake 1 flangikng 106 and sinking recess inwall 103 back taper processes are finished simultaneously.
The mould structure of the above embodiment of the present invention is simple, technological process is simple, and loam cake outer rim round edge and sinking recess inwall back taper are finished simultaneously, are suitable for high-speed automated production.
