[0050] Example 1

[0051] See also Figures 2 to 10 This embodiment provides a ring-shaped component tongue cutting and forming device for the damping belt 10 (see Figure 1 ) for tongue cutting processing, and can also be used to process other annular thin-walled sheet metal parts that require tongue cutting before forming. The annular component tongue cutting and forming device includes a tongue cutting unit 100, a rounding unit, a bending unit 200 and a shaping unit 300.

[0052] When in use, the tongue cutting unit 100 first punches the strip 20 to form a plurality of tongues 21, then the rolling unit rolls the strip 20 into a circle, and then the bending unit 200 bends the tongues 21 into spring pieces 11 (see FIG. Figure 1) to form the damping belt 10, and finally the spring piece 11 is shaped by the shaping unit 300 in conjunction with the heat treatment equipment.

[0053] Please also refer to Figures 2 to 4 Specifically, the tongue cutting unit 100 includes an upper die base 110, a punch 120, a first pressure plate 130, a driving bolt 140, a driving rod 150, a die 160, and a stopper 170. The punch 120, the first pressure plate 130, the driving bolt 140, and the driving rod 150 are all directly or indirectly mounted on the upper die base 110, while the stopper 170 is mounted on the die 160.

[0054] The upper die holder 110 is located directly above the die 160 . The die 160 remains stationary during the punching process, while the upper die holder 110 is pressed downward by the external driving structure.

[0055] The punch 120 is fixedly mounted on the bottom of the upper die holder 110. The bottom end of the punch 120 has a cutting edge. Accordingly, the upper surface of the die 160 is provided with an escape groove 161, and the escape groove 161 is located directly below the punch 120. In addition, the upper surface of the die 160 is also provided with a strip groove 162.

[0056] Please combine Figure 5 During punching, the strip material 20 is placed in the strip groove 162. The punch 120 is pressed down with the upper die base 110 to punch the strip material 20 to form the tongue 21, and the cutting edge of the punch 120 and the tongue 21 are trapped in the avoidance groove 161 together.

[0057] The first pressing plate 130 is positioned horizontally and is fixedly connected to a driving rod 150 via a driving bolt 140. Both the driving bolt 140 and the driving rod 150 are vertically slidably inserted into the upper die holder 110, thereby enabling the first pressing plate 130 to slide in engagement with the upper die holder 110. Furthermore, the first pressing plate 130 is slidably mounted on the punch 120.

[0058] During punching, the first pressing plate 130 is pressed down along with the upper die holder 110 and contacts the strip 20 before the punch 120 , pressing the strip 20 tightly against the die 160 to prevent the strip 20 from shifting or deforming during the punching process.

[0059] After the first pressing plate 130 contacts the strip 20, it stops moving, and the punch 120 continues to press down with the upper die holder 110 and passes through the first pressing plate 130 to punch the strip. During this process, the first pressing plate 130 can limit and guide the punch 120 to ensure a smooth punching process.

[0060] The top end of the driving rod 150 can be connected to an external driving structure, such as a cylinder, a spring, etc., to ensure that the first pressing plate 130 presses the strip material 20 tightly.

[0061] The limiting block 170 is detachably connected to the die 160 and has a first limiting surface 171 and a second limiting surface 172 .

[0062] When punching the first tongue 21, the first limiting surface 171 of the limiting block 170 faces the avoidance groove 161. The operator makes one end of the strip 20 abut against the first limiting surface 171 of the limiting block 170 to complete the positioning of the strip 20 and ensure the accuracy of the first tongue 21.

[0063] Afterwards, the operator removes the stop block 170 and reinstalls it, aligning the second stop surface 172 of the stop block 170 with the avoidance groove 161. The first tongue 21 is then brought into contact with the second stop surface 172 of the stop block 170, completing the positioning of the strip 20 and ensuring the accuracy of the second tongue 21. This continues in this manner, with each subsequent tongue 21 being positioned using the previous tongue 21 until all tongues 21 have been punched.

[0064] In this embodiment, the limiting block 170 is bolted to the die 160 , and the first limiting surface 171 and the second limiting surface 172 are two opposite surfaces on the limiting block 170 .

[0065] During the punching process, the strip 20 remains straight. First, the first pressing plate 130 effectively secures the strip 20, preventing deformation or breakage at the cut tongues 21. Second, the stoppers 170 precisely position the strip 20, ensuring consistent pitch between adjacent tongues 21. Clearly, performing the tongue cutting process before the strip 20 is rolled is more convenient and efficient, and also simplifies the mold design.

[0066] Specifically, the rolling unit adopts a small three-axis roller. After rolling, the strip material 20 becomes a ring structure with an opening, the diameter of which is 71.7 mm and the width of the opening is 2 mm.

[0067] See also Figure 6 Specifically, the bending unit 200 includes a base 210, a profile outer ring 220, a side push slider 230, a core cone 240, a limiting pin 250 and an elastic ring 260.

[0068] The base 210 is provided with a fixing plate 211, a mounting plate 212, and guide posts 213. The fixing plate 211 and guide posts 213 are fixedly connected to the base 210, while the mounting plate 212 is bolted to the fixing plate 211. The fixing plate 211 and mounting plate 212 are both annular in shape, with the axes of the fixing plate 211, the mounting plate 212, and the guide posts 213 coinciding.

[0069] Please also refer to Figure 6 and Figure 7The profiled outer ring 220 is embedded in the base 210 and fixedly connected to the base 210, with the axis of the profiled outer ring 220 coinciding with the axis of the fixing plate 211. A receiving groove 221 is provided on the upper portion of the inner sidewall of the profiled outer ring 220, and the receiving groove 221 is arranged along the circumference of the profiled outer ring 220. A second pressure plate 222 is embedded in the receiving groove 221. A plurality of arcuate grooves 223 are provided on the lower portion of the inner sidewall of the profiled outer ring 220, and each arcuate groove 223 is arranged along the circumference of the profiled outer ring 220.

[0070] During processing, the rolled strip 20 is placed inside the profile outer ring 220 , fits against the lower portion of the inner wall of the flat outer ring, and is pressed by the second pressing plate 222 , with each tongue 21 corresponding to each arcuate groove 223 .

[0071] In this embodiment, there are seventeen spring pieces 11 on the damping belt 10 and seventeen arcuate grooves 223 on the profile outer ring 220 . Each arcuate groove 223 is used to form one spring piece 11 .

[0072] Furthermore, the inner sidewall of the profile outer ring 220 is provided with a positioning protrusion 224. When the rolled strip 20 is placed inside the profile outer ring 220, the positioning protrusion 224 engages with the opening of the strip 20 to position the strip 20 and ensure that each tongue 21 on the strip 20 is aligned with the corresponding arc-shaped groove 223.

[0073] Please also refer to Figure 6 and Figure 8 The side push slider 230 is set on the base 210 for radial sliding along the outer ring 220 of the profile. The side push slider 230 is provided with an arc-shaped protrusion 231, and the arc-shaped protrusion 231 is opposite to one of the arc-shaped grooves 223.

[0074] The core cone 240 is slidably sleeved on the guide post 213 , and the lower portion of the core cone 240 contacts the upper portion of the side push slider 230 , and the contact surface is an inclined surface.

[0075] When the core cone 240 is driven by other structures to move downward along the guide pillar 213, it exerts downward pressure on the side push slider 230, causing it to slide radially along the profile outer ring 220. During this process, the arc-shaped protrusion 231 pushes one of the tongues 21 into the corresponding arc-shaped groove 223, causing it to bend and form the spring 11.

[0076] In this embodiment, a nut is sleeved on the guide post 213. The nut is located above the core cone 240 and is threadedly engaged with the guide post 213. When the operator screws the nut, the core cone 240 can be driven downward.

[0077] Furthermore, at least two side thrust sliders 230 are provided, and the side thrust sliders 230 are evenly distributed along the circumference of the profile outer ring 220. The core cone 240 contacts each side thrust slider 230 simultaneously, and the resultant horizontal reaction force exerted on the core cone 240 by each side thrust slider 230 is zero. This ensures that the core cone 240 and the guide pillar 213 are evenly stressed and not easily deformed.

[0078] Please also refer to Figure 8 and Figure 9 In this embodiment, there are three side push sliders 230. Accordingly, the lower surface of the mounting plate 212 is provided with three bosses 212a, evenly distributed along the circumference of the mounting plate 212. A sliding groove 212b is formed between any two adjacent bosses 212a. The three sliding grooves 212b correspond to the three side push sliders 230, and the side push sliders 230 slide in engagement with the corresponding sliding grooves 212b.

[0079] Each downward movement of the core cone 240 forms three spring pieces 11. The operator then reinstalls the side push slider 230, rotates the side push slider 230 and the mounting plate 212 by a certain angle, aligning the curved protrusion 231 on the side push slider 230 with the unbent tongue 21, and then uses the core cone 240 to drive the side push slider 230 to slide, forming three more spring pieces 11. This process is repeated until all tongues 21 are bent into spring pieces 11.

[0080] The limiting pin 250 is penetrated through the mounting plate 212 and the profile outer ring 220 along the axial direction of the mounting plate 212, which can keep the mounting plate 212 and the profile outer ring 220 relatively fixed during the processing process, ensuring that the side push slider 230 can stably cooperate with the profile outer ring 220 under the guidance of the slide groove 212b.

[0081] The elastic ring 260 is sleeved on the three side push sliders 230 . When the core cone 240 moves upward, the side push sliders 230 are driven by the elastic ring 260 to reset.

[0082] See also Figure 10 Specifically, the shaping unit 300 includes a shaping seat 310, a first ring 320, a second ring 330 and a cover plate 340, which is used in conjunction with the heat treatment equipment.

[0083] Among them, the first ring 320, the second ring 330 and the cover plate 340 are all sleeved on the shaping seat 310, and the second ring 330 is located between the first ring 320 and the cover plate 340. In addition, there is a gap between the first ring 320 and the shaping seat 310 and between the second ring 330 and the shaping seat 310.

[0084] The bottom of the side wall of the shaping seat 310 is provided with an annular protrusion, and the first ring 320 is placed on the annular protrusion. The first ring 320 is provided with a first groove 321 on the side facing the cover plate 340, and the first groove 321 can accommodate the elastic piece 11.

[0085] There is at least one second ring 330. When the number of second rings 330 exceeds one, multiple second rings 330 are stacked on the first ring 320. A second groove 331 is provided on the side of the second switch facing the cover 340. The second groove 331 can also accommodate the spring 11.

[0086] The cover plate 340 covers the top of the shaped seat 310 and presses the second collar 330. Furthermore, screws are provided through the shaped seat 310 and the cover plate 340, and pairs of nuts are fitted onto the screws. One nut abuts the bottom surface of the shaped seat 310, while the other abuts the top surface of the cover plate 340.

[0087] During shaping, the rolled strip 20 is first placed on the shaping seat 310, so that the strip 20 fits into the aforementioned gap and the spring piece 11 on the strip 20 is positioned in the first groove 321 or the second groove 331. The cover 340 is then installed, and the nuts are tightened to press the cover 340, the second collar 330, and the first collar 320 against the shaping seat 310, simultaneously compressing the spring piece 11 in the first groove 321 and the second groove 331. Finally, the shaping unit 300 is transferred to a heat treatment device to shape the spring piece 11 according to the heat treatment protocol.

[0088] In summary, when the damping band 10 is processed using the above-mentioned annular component tongue cutting 21 forming device, the strip material 20 is first punched out using the tongue cutting unit 100 to form a plurality of tongues 21. The strip material 20 after the tongues 21 are then rolled into a round shape using the rolling unit. The tongues 21 on the rolled strip material 20 are then bent to form the spring pieces 11, thereby forming the damping band 10. The strip material 20 remains straight during punching, making it easier to fix and prevent deformation or breakage at the tongue cutting 21. It is also easier to position, which helps ensure the consistency of the pitch between two adjacent tongues 21. The entire processing process is more convenient and efficient, the mold structure design is simpler, and part springback can be avoided.

[0089] Example 2

[0090] See also Figure 11 This embodiment provides a method for cutting and forming an annular component tongue, which is used to cut the tongue of the damping band 10. It can also be used to process other annular thin-walled sheet metal parts that require tongue cutting before forming. The method for cutting and forming an annular component tongue includes the following steps:

[0091] S1, using wire cutting or laser cutting to cut the unfolded material to obtain a strip material 20.

[0092] The strip 20 is made of 0Cr17Ni7Al, has a thickness of 0.17mm, and a blanking size of 240*10mm. In addition, after blanking, the strip 20 needs to be further wire-cut to reduce the size of the strip 20 to 223*6mm, and one side of the strip 20 is chamfered by 2mm*60°.

[0093] S2, removing burrs or remelted layers on the strip material 20.

[0094] S3 , punching the strip 20 to form a plurality of tongues 21 .

[0095] The first tongue 21 is 11.5 mm away from the non-chamfered end of the strip 20 , and the size of the cut tongue 21 is 2*8 mm.

[0096] S4, removing the punching burrs on the strip 20 and the tongue 21.

[0097] S5, rolling the strip material 20 after the tongue 21 is cut.

[0098] The tongue 21 formed by punching protrudes from the surface of the strip 20, so it is necessary to roll the tongue 21 along the opening direction so that the tongue 21 is located outside the rolled strip 20. The diameter of the rolled strip 20 is 71.7 mm and the opening width is 2 mm.

[0099] S6 , bending the tongue 21 on the rolled strip 20 into a spring piece 11 to form the damping belt 10 .

[0100] S7, heat treatment is performed on the spring piece 11 to finalize its shape.

[0101] After shaping, the hardness of the damping tape 10 is HV423-509.
