[0029] like Figure 6-7 As shown, this example can achieve the effect of forming a part with an upper portion being a cylindrical portion 402 and a lower portion being a flat circular portion 401 .

[0030] Since the sheet metal stamping equipment includes a flat seat 201, a center hole 203 is provided at the center of the flat seat 201, and the flat seat 201 is vertically slidably connected to the cylinder 207 through the center hole 203, and a pad 208 is welded to the lower end of the cylinder 207. The metal plate is cut into a circle, and then a center hole is punched in the center of the circular metal plate, and then the circular metal plate is placed on the upper side of the flat seat 201, so that the center hole is placed on the upper side of the cylinder 207; then the metal plate is pressed into the cylinder 207, so that the cylinder 207 is inserted into the center hole on the metal plate, so that the center hole is expanded, and the metal plate is then sleeved on the cylinder 207 to form a cylindrical portion 402; finally, a part with the upper part being the cylindrical portion 402 and the lower part being the flat circular portion 401 is formed.

[0031] like Figure 4-7 As shown, this example can achieve the effect that the flat seat 201 drives the stamped parts to move upward, so that the parts are separated from the cylinder 207.

[0032] Since the pad 208 is welded to the upper side of the flat plate 101, round rods 205 are welded to the left and right ends of the lower side of the flat seat 201. The two round rods 205 are vertically slidably connected to the flat plate 101. A stop pin 206 is inserted at the lower end of each round rod 205. A compression spring 204 is sleeved on each round rod 205. The compression spring 204 is located between the flat seat 201 and the flat plate 101. The compression spring 1 204 applies an upward elastic force to the two round rods 205 and the flat seat 201, so that the flat seat 201 is usually at the same height as the cylinder 207. When the metal plate is subjected to pressure, the outer edge of the metal plate moves downward, driving the flat seat 201 to move downward, and the inner edge of the metal plate is stretched after being sleeved on the cylinder 207, thereby forming a part with an upper portion being a cylindrical portion 402 and a lower portion being a flat circular portion 401. Then, when the pressure on the metal plate is removed, the two compression springs 1 204 drive the flat seat 201 to move upward, and the flat seat 201 drives the stamped part to move upward, so that the part is separated from the cylinder 207.

[0033] like Figure 4-9 As shown, this example can achieve the effect of applying pressure to the metal plate.

[0034] Since two guide rods 305 are welded on the flat plate 101, side seats 304 are welded on both the left and right ends of the pressure ring 301, and the two side seats 304 are respectively slidably connected to the two guide rods 305, the pressure ring 301 is located above the cylinder 207, the inner diameter of the pressure ring 301 is larger than the outer diameter of the cylinder 207, and the upper side of the flat seat 201 is provided with a plurality of convex ridges 202 in an annular shape. The upper part of each guide rod 305 is connected to a telescopic rod 2 307 by screws, and the movable ends of the two telescopic rods 2 307 are respectively connected to the two side seats 304 by screws. When the two telescopic rods 307 are extended or retracted, the two side seats 304 are driven to slide vertically on the two guide rods 305 respectively, thereby driving the pressure ring 301 to move downward. When the pressure ring 301 moves downward, it presses against the metal plate placed on the flat seat 201, thereby applying pressure to the metal plate, so that the inner edge of the metal plate is expanded after being sleeved on the cylinder 207, thereby forming a part with an upper portion being a cylindrical portion 402 and a lower portion being a flat circular portion 401; when the flat seat 201 moves to contact the cushion block 208, the pressure ring 301 continues to press on the metal plate, so that the lower side of the metal plate is pressed against the multiple ridges 202, thereby forming a multiple anti-slip linear grooves 403 on the lower side of the flat circular portion 401 to prevent the part from slipping during use.

[0035] like Figure 8-9 As shown, this example can prevent the metal plate from moving freely between the flat seat 201 and the cylinder 207.

[0036] Since both left and right ends of the upper side of the pressure ring 301 are welded with vertical rods 306, the pressure block 302 is slidably connected to the pressure ring 301, and both left and right ends of the upper part of the pressure block 302 are welded with convex pieces 309, and the two convex pieces 309 are respectively vertically slidably connected to the two vertical rods 306, and the upper parts of the two vertical rods 306 are fixed with blocking pieces 308, and each vertical rod 306 is sleeved with a second compression spring 310, and the second compression spring 310 is located between the blocking piece 308 and the convex piece 309. The lower ends of the two stop pins 303 are inserted, and the two stop pins 303 are blocked at the lower sides of the two protruding pieces 309 respectively. The compression spring 310 gives the two protruding pieces 309 a downward force, so that the pressing block 302 always has a tendency to move downward, and then when the pressing ring 301 presses against the metal plate, the pressing block 302 will always be pressed against the middle hole on the metal plate by the elastic force of the two compression springs 310, and then the metal plate is positioned to prevent the metal plate from moving freely on the flat seat 201 and the cylinder 207. The two middle holes 203 limit the two protruding pieces 309 respectively, preventing the two protruding pieces 309 and the pressing block 302 from moving too far downward relative to the vertical rod 306.

[0037] like Figure 4-5 As shown, this example can achieve the effect of supporting the tablet 101 through the two legs 110 .

[0038] Since two supporting legs 110 are welded to the lower side of the flat plate 101 , the flat plate 101 is supported by the two supporting legs 110 .

[0039] like Figure 4-5 As shown, this example can achieve the effect of placing a metal plate of any shape on the upper side of the ring hole 102 and the circular hole 108 .

[0040] Since the right end of the flat plate 101 is provided with an annular hole 102 and a circular hole 108, the circular hole 108 and the annular hole 102 are coaxially arranged, and two supporting legs 109 are connected to the lower side of the right end of the flat plate 101 by screws, and the supporting legs 109 connect the inner part and the outer part of the annular hole 102 together, and the flat plate 101 at the annular hole 102 and the circular hole 108 is supported by the two supporting legs 109, and a metal plate of any shape can be placed on the upper side of the flat plate 101 first, so that the metal plate of any shape is placed on the upper side of the annular hole 102 and the circular hole 108.

[0041] like Figure 4-5 As shown, this example can achieve the effect of cutting a metal plate into a circle and then punching a hole in the center of the circular metal plate.

[0042] Since an L-shaped frame 103 is welded on the flat plate 101, a square column 104 is vertically slidably connected to the L-shaped frame 103, a telescopic rod 111 is connected to the L-shaped frame 103 by screws, and the movable end of the telescopic rod 111 is connected to the upper part of the square column 104 by screws, and the lower end of the square column 104 is connected to a cross 106 by screws, and the lower side of the cross 106 is connected to a ring knife 105 and a ring knife 2 107 by screws, and the ring knife 105 is located above the ring hole 102. The square column 104 and the cross 106 can be driven downward by the telescopic rod 111, thereby driving the ring cutter 105 and the ring cutter 107 to move downward, so that the ring cutter 105 cuts toward the ring hole 102, and the ring cutter 107 cuts toward the circular hole 108, thereby cutting a metal plate of any shape placed on the flat plate 101, cutting the metal plate into a circle, and then punching a center hole in the center of the circular metal plate.

[0043] A sheet metal stamping device is used for a method of stamping sheet metal, comprising the following steps;

[0044] S1: Cut the metal plate into a circle, and then punch a hole in the center of the circular metal plate;

[0045] S2: Place the circular metal plate on the upper side of the flat seat 201 so that the middle hole is placed on the upper side of the cylinder 207;

[0046] S3: driving the pressing ring 301 to press against the metal plate, so that the cylinder 207 is inserted into the middle hole of the metal plate, so that the middle hole is expanded, and the metal plate is now sleeved on the cylinder 207 to form a cylindrical portion 402;

[0047] S4: Finally, a part is formed with an upper cylindrical portion 402 and a lower flat circular portion 401.
