[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0028] This utility model provides a pedal stamping and flanging fixture, the structure of which is as follows: Figure 1 - Figure 7 As shown, it includes a support mechanism 2 and a flange mechanism 1.

[0029] The support mechanism 2 includes a support base 21 and a positioning part 22. The positioning part 22 is disposed on the support base 21. The support base 21 is used to place the pedal, and the positioning part is used to position the pedal.

[0030] The flanging mechanism 1 includes a flanging seat 11, a flanging head 12, and a flanging drive. The flanging head 12 is connected to the flanging seat 11. The support seat 21 is provided with a flanging cavity 13 for accommodating the flanging head 12. The flanging drive is used to drive the flanging seat 11 to move toward or away from the support seat 21. When the flanging head 12 reaches the flanging cavity 13, the flanging head 12 abuts against the side of the pedal and pushes the side to flip into the flanging cavity 13.

[0031] In use, the pedal is placed on the support base 21, ensuring that the through hole of the pedal accurately aligns with the positioning part 22 to guarantee the correct pedal position. Then, the stamping equipment is started, and the cylinder drives the flanging seat 11 and its flanging head 12 downwards. The flanging head 12 initially contacts the edge of the hole on the pedal and applies pressure, causing plastic deformation of the metal material at the hole edge. As the flanging head 12 continues to move downwards, the metal material flows into the corresponding flanging cavity 13, forming the desired flanging shape under the guidance of the flanging cavity 13. Throughout the process, the positioning part 22 ensures the pedal position is fixed, and the flanging head 12 and the flanging cavity 13 work together to achieve the stamping and flanging operation of the pedal.

[0032] In this invention, the precise positioning of the pedal by the positioning part 22 and the shape guidance and constraint of the flanging process by the flanging cavity 13 can ensure accurate flanging position and improve the dimensional accuracy of the product. When flanging multiple holes of the pedal, the position of each flanging can be highly consistent with the design requirements, ensuring product consistency and improving production efficiency.

[0033] For easier replacement of the flange head 12, please refer to... Figure 1 In a preferred embodiment, a plurality of the flange heads 12 are detachably connected to the flange seat 11.

[0034] In use, the pedals come in various specifications during production, and the shape and size of the flange head 12 required for different specifications of pedals are different. The flange head 12 is detachable, which makes it convenient to quickly replace the flange head 12 with a suitable one for different products.

[0035] For easier replacement of the flange head 12, please refer to... Figure 3 In a preferred embodiment, the flange seat 11 includes a pressure plate 111, a mounting plate 112, and a first bolt 113. A limiting plate 114 is connected to one side of the flange head 12. The mounting plate 112 is provided with a plurality of positioning holes 115 for accommodating the flange head 12. The top of the mounting plate 112 is provided with a plurality of limiting grooves 116 for accommodating the limiting plate 114. The first bolt 113 is used to press the pressure plate 111 onto the mounting plate 112, thereby pressing the pressure plate 111 against the top of the flange head 12.

[0036] In use, a limiting plate 114 is provided on one side of the flanging head 12, while the mounting plate 112 has multiple positioning holes 115 for accommodating the flanging head 12 and limiting grooves 116 for accommodating the limiting plate 114. When installing the flanging head 12, the main body of the flanging head 12 is inserted into the positioning hole 115, and the limiting plate 114 is simultaneously inserted into the corresponding limiting groove 116. This design ensures the accurate position of the flanging head 12 on the mounting plate 112 and prevents its displacement in the horizontal direction. After the flanging head 12 is installed, the pressure plate 111 is pressed onto the mounting plate 112 using the first bolt 113. When the first bolt 113 is tightened, the pressure plate 111 will press against the top of the flanging head 12. According to the principle of pressure transmission, the pressure plate 111 will apply a downward pressure to the flanging head 12, firmly fixing the flanging head 12 in the positioning hole 115 and the limiting groove 116. This fixing method ensures that the flange head 12 will not move up or down or loosen during operation.

[0037] To accommodate pedals of different thicknesses, please refer to [reference needed]. Figure 4 In a preferred embodiment, the pressure plate 111 is provided with an adjustment component 3 for adjusting the depth of the flanging head 12 entering the flanging cavity 13.

[0038] In use, pedals of different thicknesses exhibit varying performance during stamping and flanging. These differences can be accommodated by adjusting the depth of the flanging head 12 entering the flanging cavity 13. For thinner pedal materials, the entry depth of the flanging head 12 can be appropriately reduced to prevent material breakage or excessive deformation due to over-flanging; for thicker pedal materials, the depth can be appropriately increased to ensure the flanging effect. This allows the tooling to flexibly adapt to pedals of different materials and thicknesses, expanding its applicability and improving its adaptability to different process requirements.

[0039] To adjust the depth of the flange head 12, please refer to... Figure 6 In a preferred embodiment, the adjusting component 3 includes a plurality of pressure blocks 31 and a plurality of springs. The plurality of pressure blocks 31 are disposed at the bottom of the pressure plate 111 and abut against the top of the flange head 12. The pressure blocks 31 have various height specifications. The springs are disposed between the limiting plate 114 and the limiting groove 116. The top of the springs is fixedly connected to the bottom of the limiting plate 114 and the bottom of the springs is fixedly connected to the bottom wall of the limiting groove 116. The springs are in a compressed state, and the springs cause the flange head 12 to tend to slide toward the pressure blocks 31.

[0040] During use, the spring generates an upward elastic force, pushing the flanging head 12 towards the pressure block 31. Based on the expected depth of the flanging head 12 entering the flanging cavity 13, a suitable pressure block 31 is selected from various height specifications and installed at the bottom of the pressure plate 111, abutting against the top of the flanging head 12. The height of the pressure block 31 determines the initial position of the flanging head 12 relative to the flanging cavity 13, thus initially setting the flanging depth. When the flanging seat 11 drives the flanging head 12 downward to press against the pedal, the spring acts as a buffer. At the moment the flanging head 12 contacts the pedal, the spring reduces the impact force, preventing damage to the flanging head 12 or the pedal due to excessive impact. Simultaneously, based on differences in the thickness and hardness of the pedal material, the spring can adaptively adjust the position of the flanging head 12 to ensure stable flanging quality. After stamping is complete, the flanging seat 11 rises, the external force disappears, and the spring's elastic force returns the flanging head 12 to its initial position, preparing for the next stamping.

[0041] To make it easier to align the pedal with the positioning part 22, please refer to... Figure 5 In a preferred embodiment, the positioning part includes a positioning block 22, and the top periphery of the positioning block 22 is provided with a rounded chamfer 23.

[0042] When the pedal is placed on the support base 21 during use, the rounded chamfer 23 on the top of the positioning block 22 serves as a guide. When the through hole of the pedal is close to the positioning block 22, the chamfer guides it to be smoothly aligned with the positioning block 22, so that the operator can quickly and accurately achieve positioning without having to repeatedly adjust the position.

[0043] For easier maintenance of support base 21, please refer to... Figure 7 In a preferred embodiment, the support base 21 includes a base 211, a base plate 212, a plurality of positioning posts 213 and a plurality of second bolts 214. The plurality of positioning posts 213 are disposed on the base plate 212. The base 211 is provided with positioning through holes 215 adapted to the positioning posts 213. The second bolts 214 are inserted into the base 211 and threadedly connected to the base plate 212.

[0044] During use, when assembling the support base 21, align the positioning pin 213 on the base plate 212 with the positioning through hole 215 on the base 211, and then insert the positioning pin 213 into the positioning through hole 215. This mating method ensures the accurate relative position of the base 211 and the base plate 212 in the horizontal direction, playing a preliminary positioning role. After the positioning pin 213 is inserted into the positioning through hole 215 for preliminary positioning, the base 211 and the base plate 212 are further connected together by the second bolt 214. The assembled support base 21 provides a stable support platform for the positioning block 22 and the flanging cavity 13. It is an important foundation for ensuring the smooth operation of the pedal stamping and flanging.

[0045] To improve the overall aesthetics and flatness of the workwear, please refer to... Figure 7 In a preferred embodiment, the base 211 is provided with a countersunk groove 216 for accommodating the second bolt 214.

[0046] In use, the countersunk groove 216 allows the head of the second bolt 214 to be embedded inside the base 211, preventing the bolt head from protruding from the surface of the base 211. Within a limited space, the additional space occupied by the bolt head will not affect the layout of other components of the tooling or its coordination with surrounding equipment.

[0047] To align base 211 with flange seat 11, please refer to... Figure 7 In a preferred embodiment, the base 211 is provided with a guide post 24, the flange seat 11 is provided with a guide hole 25, the guide post 24 is located inside the guide hole 25, and the outer wall of the guide post 24 abuts against the inner wall of the guide hole 25.

[0048] During use, the cooperation between the guide post 24 and the guide hole 25 precisely guides the flanging seat 11 to move vertically, ensuring that the flanging head 12 is accurately aligned with the part on the pedal to be flanged. This guarantees precise flanging positioning and thus improves product accuracy.

[0049] For easy handling of base plate 212, please refer to... Figure 7 In a preferred embodiment, the base plate 212 is provided with a handle 26.

[0050] During use, the tooling position sometimes needs to be adjusted according to the production process or site layout. The handle 26 on the base plate 212 provides operators with a convenient point of force application, enabling them to easily push or pull the tooling to move it to the required position.

[0051] To better understand this utility model, the following is combined with... Figure 1 - Figure 7 The working principle of a pedal stamping and flanging fixture according to this utility model is described in detail below: The pedal is placed on the support base 21, ensuring that the through hole of the pedal accurately aligns with the positioning part 22 to guarantee the correct pedal position. Then, the stamping equipment is started, and the cylinder drives the flanging seat 11 and its flanging head 12 downwards. The flanging head 12 initially contacts the edge of the hole on the pedal and applies pressure, causing plastic deformation of the metal material at the hole edge. As the flanging head 12 continues to move downwards, the metal material flows into the corresponding flanging cavity 13, forming the desired flanging shape under the guidance of the flanging cavity 13. Throughout the process, the positioning part 22 ensures the pedal position is fixed, and the flanging head 12 and the flanging cavity 13 work together to realize the stamping and flanging operation of the pedal.

[0052] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
