[0044] As shown in Figures 1, 2, and 3, a hardware stamping equipment according to one embodiment of the present invention includes a feeding device 1, a conveying track 2, and a punching and turning device 3 and a stamping device 4 arranged sequentially along the length of the conveying track 2; the conveying track 2 is provided with punching positions 201, turning positions 202, and stamping positions 203 in sequence; the feeding device 1 includes a feeding component, which conveys the workpiece onto the conveying track 2, and the workpiece is an iron shell with a lower opening; the punching and turning device 3 includes a first bracket 31 and a... The first support 31 includes a punching component 32 and a flipping component 33. The punching component 32 is used to punch the top of the iron shell at the punching position 201, and the flipping component 33 is used to flip the top of the iron shell at the flipping position 202. The stamping device 4 includes a stamping drive component 5, a positioning component 6, and a first stamping component 7. The positioning component 6 is used to position the iron shell at the stamping position 203, and the stamping drive component 5 drives the first stamping component 7 to stamp the positioned iron shell.

[0045] The aforementioned metal stamping equipment uses the punching component 32 to punch the top of the iron shell at the punching position 201, and the flipping component 33 to flip the top of the iron shell at the flipping position 202, thereby turning the hole at the top of the iron shell into a flipped edge with a larger connection length. Subsequently, thread processing is used to form a threaded connection to meet the connection strength requirements. The stamping drive component 5 drives the first stamping component 7 to stamp the positioned iron shell, forming ventilation slots around the circumference of the iron shell to meet the subsequent assembly requirements.

[0046] In one specific embodiment, the iron shell is a round shell with a bottom opening.

[0047] In one embodiment, the feeding device 1 is a vibrating feeding plate.

[0048] In one embodiment, the stamping drive component 5 includes a stamping drive block 51; the first stamping component 7 includes a stamping bracket 71, a first stamping seat 72 slidably connected to the stamping bracket 71, and a first spring-loaded assembly 73 that springs the stamping drive block 51 away from the first stamping seat 72; the first stamping seat 72 is provided with a first driving ramp 721 and a first stamping flange 722. Thus, the first driving ramp 721 is in contact with the stamping drive block 51 through the first ramp structure, and the first stamping flange 722 faces the stamping position 203.

[0049] In one embodiment, the first stamping seat 72 is provided with a second stamping flange 723, which is located below the first stamping flange 722. Thus, the second stamping flange 723 stamps the side edge of the lower opening of the iron shell, thereby achieving the processing action of the first positioning notch on the side edge.

[0050] As shown in Figures 3, 4, and 5, in one embodiment, the first stamping component 7 includes two second stamping assemblies 74 respectively disposed on both sides of the first stamping seat 72; the second stamping assembly 74 includes a second stamping seat 741 slidably connected to the stamping bracket 71, the second stamping seat 741 having a second driving inclined surface 742 and a third stamping flange 743. Thus, the second driving inclined surface 742 is in contact with the stamping driving block 51 through the second inclined surface structure, and the third stamping flange 743 faces the stamping position 203, thereby forming a machining action of the second positioning notch along the side.

[0051] In one embodiment, the second stamping flange 723 and the third stamping flange 743 are arranged perpendicularly.

[0052] In one embodiment, the positioning component 6 includes an upper positioning component 61 and a lower positioning component 62. The lower positioning component 62 includes a support base 621 disposed below the stamping position 203 and a lower positioning drive 622 for driving the support base 621 to move up and down. The upper positioning component 61 includes a top pressure seat 611 disposed above the stamping position 203 and an upper positioning drive 612 for driving the top pressure seat 611 to move up and down. A positioning space for the metal shell is formed between the support base 621 and the top pressure seat 611. The support base 621 is provided with a guide channel adapted to the second stamping flange 723 and the third stamping flange 743. Thus, by providing a guide channel adapted to the second stamping flange 723 and the third stamping flange 743 in the support base 621, when the second stamping flange 723 and the third stamping flange 743 stamp the bottom of the metal shell, an accurate stamping notch can be formed along the guide channel.

[0053] In one embodiment, both the first stamping seat 72 and the second stamping seat 741 are slidably connected to the stamping bracket 71 via a dovetail groove structure 8. Specifically, the dovetail groove structure 8 includes a dovetail groove body disposed on the stamping bracket 71 and dovetail slides respectively disposed on the first stamping seat 72 and the second stamping seat 741.

[0054] As shown in Figures 2, 6, and 7, in one embodiment, the punching component 32 includes a stamping assembly 321 disposed above the punching position 201 and a stamping cylinder assembly 322 that drives the stamping assembly 321 to perform the stamping action; the flipping component 33 includes a flipping positioning assembly 331 disposed above the flipping position 202, a flipping impact assembly 332 disposed below the flipping position 202, and a flipping drive assembly 333 that drives the flipping positioning assembly 331 and the flipping impact assembly 332 to move closer to each other.

[0055] In one embodiment, a limiting device 9 is also included; the limiting device 9 includes a first limiting component 91 and a second limiting component 92, the first limiting component 91 being used to limit the workpiece before the punching position 201, and the second limiting component 92 being used to limit the workpiece before the stamping position 203.

[0056] In one embodiment, both the first limiting component 91 and the second limiting component 92 include a limiting assembly 93. The limiting assembly 93 includes a limiting drive cylinder 931, a limiting seat 932, a swing block 933 rotatably connected to the limiting seat 932, and a limiting strip 934 slidably connected to the limiting seat 932. The limiting strip 934 has a sliding end, an extended end, and a pin 935 disposed between the sliding end and the extended end. The swing block 933 has an input part hinged to the output end of the limiting drive cylinder 931, a rotating part hinged to the limiting seat 932, and a swing arc groove adapted to the pin 935. Thus, the input part of the swing block 933 is driven by the limit drive cylinder 931. The swing block 933 is pushed around the rotating part and the pin 935 in the swing arc groove is pushed. The limit bar 934 approaches the conveying track 2 along the limit hole of the limit seat 932. The top of the limit bar 934 is limited between the two iron shells, thereby limiting the iron shells continuously conveyed in the conveying track 2.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
