[0041] Working principle: First, drive the die 1 to move upward to drive the lifting plate 12 and the positioning plate 13 to move upward, and push the steel plate 6 horizontally from the back to the front to the top of the first carrier plate 32 in the first molding component 3, and then feed it forward along the top of the first carrier plate 32 at a certain speed. At the same time, the die 1 will also repeatedly move up and down at a certain frequency. When the positioning plate 13 presses the steel plate 6 against the top of the first carrier plate 32, the positioning plate 13 will retract upward to allow the lifting plate 12 to continue to move downward for a certain distance; when the die 1 moves upward to allow the positioning plate 13 to leave the first carrier plate 32, the positioning plate 13 will move downward elastically to reset. The above structure and principle are all prior art.

[0042] When the steel plate 6 moves to above the first auxiliary block 33 in the first forming unit, the die 1 just moves downward, so that the bottom of the lifting plate 12 is pressed against the steel plate 6 to prevent the steel plate 6 from shifting; then, the lower end of the first L-shaped cutting column 34 passes through the steel plate 6 and extends into the first cutting notch 331 and punches out a first L-shaped scrap 61 of the steel plate 6, thereby forming an L-shaped notch 62 on the steel plate 6; thereafter, the die 1 moves up and resets.

[0043] When the L-shaped notch 62 moves to above the second auxiliary block 37 in the second molding unit, the die 1 just moves downward again, and the lower end of the first bending column 35 extends into the first bending notch 371 to punch the L-shaped notch 62 into an L-shaped flange 63, after which the die 1 moves up and resets.

[0044] When the L-shaped flange 63 moves to above the third auxiliary block 312 in the third molding unit, the die 1 just moves downward again, and the lower end of the second L-shaped cutting column 310 extends into the first L-shaped notch groove 3121, and then cuts off a second L-shaped scrap 64 at the right rear of the L-shaped flange 63. After that, the stamping die 1 will move up and reset.

[0045] When the L-shaped flange 63 moves to above the fourth auxiliary block 313 in the fourth molding unit, the die 1 just moves downward again, and the lower end of the third L-shaped cutting column 311 extends into the second L-shaped notch groove 3131, and then a third L-shaped scrap 65 is cut off at the right front of the L-shaped flange 63. After that, the stamping die 1 will move up and reset.

[0046] When the L-shaped flange 63 moves to above the fifth auxiliary block 38 in the fifth forming unit, the die 1 just moves downward again, and the end of the second bending column 39 presses the steel plate 6 downward so that it forms a step bending portion 66 with the help of the second bending notch 381 on the fifth auxiliary block 38.

[0047] Next, the steel plate 6 moves forward to above the second carrier plate 42 in the second forming assembly 4, and then feeds forward along the top of the second carrier plate 42 at a certain speed. When the step bending portion 66 moves to above the fifth auxiliary block 38 at the rearmost position in the sixth forming unit, the die 1 just moves downward again, and the lower ends of the two hole-flanging columns 412 pass through the steel plate 6 and are respectively inserted into the countersunk holes 431 on the two sixth auxiliary blocks 43, thereby forming two flanging holes 67 on the step bending portion 66. After that, the stamping die 1 moves up and resets.

[0048] When the L-shaped flange 63 moves to above the seventh auxiliary block 46 in the seventh forming unit, the die 1 just moves downward again, and the lower end of the Y-shaped cutting column 45 will pass through the steel plate 6 and extend into the Y-shaped groove 461, and then punch out a Y-shaped scrap 68 on the steel plate 6, thereby forming a hook 69 behind the L-shaped flange 63. After that, the stamping die 1 will move up and reset.

[0049] When the hook 69 moves to the top of the material cavity 421, the die 1 just moves downward again, and the lower end of the sixth bending column 48 presses the end of the hook 69 into the material cavity 421 to bend the end of the hook 69, after which the stamping die 1 moves up and resets.

[0050] When the hook portion 69 moves to the top of the eighth auxiliary block 410, the die 1 just moves downward again, and the first columnar boss 471 on the first punching block 47 will pass through the steel plate 6 upward under the action of the positioning plate 13 and form a first circular hole 610 in the hook portion 69. After that, the stamping die 1 will move up and reset.

[0051] When the hook portion 69 moves to above the eighth auxiliary block 410 in the eighth molding unit, the die 1 just moves downward again, and the lower end of the fourth L-shaped cutting column 49 passes through the steel plate 6 and extends into the third L-shaped notch groove 4101, and then punches out a fourth L-shaped scrap 611 on the left rear side of the hook portion 69. After that, the stamping die 1 moves up and resets.

[0052] Next, the steel plate 6 moves forward to above the third carrier plate 52 in the third forming assembly 5, and then feeds forward along the top of the third carrier plate 52 at a certain speed. When the hook 69 moves to the end and moves above the first forming cavity 521 in the third forming assembly 5, the die 1 just moves downward again, and the lower end of the third bending column 53 will extend into the first forming cavity 521 to bend the left side of the hook 69 downward into the inclined portion 612. After that, the stamping die 1 will move up and reset.

[0053] When the inclined portion 612 moves to the top of the second molding cavity 522, the stamping die 1 just moves downward again, and the lower end of the fourth bending column 54 will extend into the second molding cavity 522 to continue to bend the inclined portion 612 downward, thereby expanding the bending angle of the inclined portion 612, and then the stamping die 1 will move up and reset.

[0054] When the inclined portion 612 moves to the top of the inner lining block 56, the stamping die 1 just moves downward again, and the arc-shaped notch cavity 551 located at the lower end of the fifth bending column 55 will shape the bending angle of the inclined portion 612 with the help of the arc-shaped shaping surface 561, and then the stamping die 1 will move up and reset.

[0055] When the steel plate 6 moves to the top of the second punching block 59, the die 1 just moves downward again, and the second columnar boss 591 on the second punching block 59 will pass through the steel plate 6 upward under the action of the positioning plate 13 and form a second circular hole 613 on the right side of the inclined portion 612. After that, the stamping die 1 will move up and reset.

[0056] Finally, when the steel plate 6 moves to the top of the guide block 58, the die 1 moves downward again, and the lower end of the punching column 57 passes through the steel plate 6 and extends into the punching cavity 581, thereby removing the remaining connection between the rear side of the inclined portion 612 and the steel plate 6, thereby finally forming a separate speaker bracket 614 and falling out forward one by one to achieve continuous stamping.

[0057] The utility model integrates all the processes involved in processing the automobile horn bracket into a set of forming dies by means of continuous stamping, thereby greatly simplifying the processing steps and significantly improving the processing efficiency; and there is no need to split the processes involved in processing the automobile horn bracket into multiple steps, and there is no need to manufacture a corresponding number of matching forming dies, thereby reducing the cost for manufacturing the dies and reducing the processing cost.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
