Technical Field
[0001] This utility model belongs to the field of saddle production, and in particular relates to a saddle beam stamping and shaping tool. Background Technology
[0002] As people's living standards improve, there are more and more vehicles in cities. For convenient travel and health management, people are increasingly willing to choose electric bikes or bicycles. The number of electric bike and bicycle brands on the market is also increasing. The saddle is a crucial functional part of electric bikes and bicycles that comes into direct contact with the human body. Below the saddle is the saddle beam. Because the saddle beam is extruded, sharp corners are prone to appearing at the front, and bending deformation, unstable gap spacing, or inconsistent gap dimensions are common in the straight section of the saddle beam. If these problems are not resolved, they can lead to issues after the saddle beam is assembled under the saddle, ultimately making it difficult to guarantee that the finished saddle will 100% meet design and customer requirements. This causes problems for subsequent assembly of saddle accessories, customer vehicle assembly, and product quality, and also affects the stability and comfort of the saddle. To address the persistent problems with saddle beams after extrusion, existing methods rely on manual shaping using specialized clamps. However, this method is labor-intensive, inefficient, dependent on human experience, and prone to unpredictable issues. Other methods utilize independent fixtures for leveling, but these are extremely time-consuming and labor-intensive, unable to achieve high precision quickly, and costly. Furthermore, different saddle beam shaping fixtures require complete sets of fabrication, further increasing equipment costs. Therefore, there is an urgent need to develop a highly automated saddle beam shaping machine that offers excellent shaping results, fast shaping speed, and convenient switching between different saddle beam shaping methods.

[0025] like Figure 1-5As shown, the saddle beam stamping and forming fixture includes a support platform 1 and a saddle beam forming seat 3 slidably disposed above the support platform 1 and movable left and right relative to the support platform 1. Above the support platform 1 is a pressing head 2 that can move up and down driven by a vertical pressing cylinder (not shown). The pressing head 2 is located above the saddle beam forming seat 3. The saddle beam forming seat 3 includes a base plate 7 and, from front to back, a front support part 4, a middle support part 5, and a rear stop block 6 of the saddle beam, all detachably disposed on the base plate 7. The base plate 7 can move left and right relative to the support platform 1. The front side of the base plate 7 is also fixedly connected to the movable end of a horizontal linear drive device 9, which is fixedly connected to the support platform 1 to facilitate automated left and right movement of the base plate relative to the support platform. The front support part 4 and the middle support part 5 of the saddle beam are correspondingly provided with parts that correspond to the saddle beam 1. The front pointed structure and the middle straight section structure of the saddle beam 10 have matching grooves to support the saddle beam 10 when the pressing head 2 presses downwards. The saddle beam tail stop 6 can abut against the tail of the saddle beam after the saddle beam 10 is placed on the saddle beam shaping seat 3. The pressing head 2 includes a pressing block 11 fixedly connected to the movable end of the vertical pressing cylinder and a front flattening punch 12 and a middle flattening punch 13 fixedly arranged below the pressing block 11 with a flat bottom surface. The positions and bottom structures of the flattening punch 12 and the middle flattening punch 13 are adapted to the positions and top structures of the front support part 4 and the middle support part 5 of the saddle beam on the saddle beam shaping seat 3, so that when the pressing head 2 impacts and presses down, the front flattening punch 12 and the middle flattening punch 13 can cooperate with the front support part 4 and the middle support part 5 of the saddle beam to flatten and shape the front tip structure and the middle straight section structure of the saddle beam 10.
[0026] The horizontal linear drive device 9 is a horizontal push cylinder.
[0027] The front support part 4, the middle support part 5, and the rear stop block 6 of the saddle beam are all detachably mounted on the base plate 7 by fixing bolts.
[0028] The saddle beam tail stop 6 has an L-shaped structure and an adjusting elongated hole 14 on the side that contacts the base plate 7. The saddle beam tail stop 6 and the base plate 7 are fixed together by fixing bolts passing through the adjusting elongated hole 14. By providing the adjusting elongated hole 14, the front and rear positions of the saddle beam tail stop 6 can be flexibly adjusted so that it can be adjusted at any time as needed.
[0029] The top of the front support part 4 of the saddle beam is an inclined structure adapted to the orientation of the saddle beam structure, and the bottom structure of the front flattening punch 12 is an inclined structure that matches the inclined structure at the top of the front support part 4 of the saddle beam.
[0030] A through groove 17 with a flat bottom is horizontally excavated on the top of the saddle beam support 5. The groove on the saddle beam support 5, which matches the structure of the straight section in the middle of the saddle beam 10, is located at the bottom of the two side walls of the through groove 17. The bottom structure of the middle flattening punch 13 is adapted to the structure of the through groove 17.
[0031] A groove 15 is cut into the upper surface of the support platform 1. A sliding strip 16 that can cooperate with the groove 15 is fixedly connected to the bottom of the base plate 7 on the saddle beam shaping seat 3. Through the cooperation of the groove 15 and the sliding strip 16, the base plate 7 can move left and right relative to the support platform 1.
[0032] On both sides of the base plate 7, there is an inverted L-shaped stop 8 with a hook facing inward, which can be used to press down the base plate. The inverted L-shaped stop 8 is fixedly installed on the support platform 1. The two inverted L-shaped stop 8 are arranged opposite each other, which can guide and limit the movement of the base plate 7.
[0033] The central flattening punch 13 is made of urethane. By using urethane, it has the advantages of small deformation and some plasticity. During the flattening process, it presses down on the middle section of the saddle beam, which can play a role in fixing and shaping without damaging the saddle beam.
[0034] The front flattening punch 12 is made of Cr12MOV mold steel to avoid deformation after long-term use.
[0035] Work process:
[0036] When the saddle beam needs to be shaped, the saddle beam shaping seat is pushed out of the shaping station away from the pressing head by a horizontal linear drive device for manual loading of the saddle beam. During loading, the saddle beam is first placed on the saddle beam shaping seat, with its front pointed structure and middle straight section structure positioned sequentially at the corresponding positions of the front support and middle support of the saddle beam. Then, the front and rear positions of the saddle beam tail stop are adjusted so that it can hold the tail of the saddle beam and prevent the saddle beam from moving excessively during the flattening and stamping process, thus positioning the saddle beam. After loading, the saddle beam shaping seat is pulled into the shaping station directly below the pressing head by a horizontal linear drive device for flattening and shaping of the saddle beam. During flattening and shaping, the pressing head presses downwards, working together with the saddle beam shaping seat to complete the shaping of the saddle beam. After shaping, the saddle beam shaping seat is pushed out of the shaping station by a horizontal linear drive device for unloading and reloading of the saddle beam.
[0037] During this process, the inverted L-shaped stop is used to press down the base plate, preventing it from detaching from the support platform during operation. The support platform has a sliding groove, allowing it to slide smoothly with the base plate. Replacing the base plate is also easy, without needing to disassemble the support platform. The base plate has a sliding strip, which is convenient to match with the support platform and is easy to replace, making it very convenient.
[0038] When different saddle beams need to be reshaped, it is only necessary to replace the saddle beam front support and saddle beam middle support on the base plate of the saddle beam correction seat or the saddle beam middle support as a whole.
[0039] This utility model's saddle beam stamping and forming fixture has an ingenious structure. Through clever support and flattening impact at various points on the saddle beam, it achieves excellent flattening and stamping forming effects. Furthermore, the horizontal linear drive device can automatically push the saddle beam forming seat out or pull it into the forming station, resulting in a high degree of automation and operational safety. When different saddle beams need to be formed, only one saddle seat straightening seat or the front and middle support parts of the saddle beam on the base plate of the saddle seat straightening seat needs to be replaced accordingly. In other words, the forming molds for different saddle beams can be changed simply, flexibly, and quickly. The equipment cost is low, and it is highly practical, making it worthy of promotion.
[0040] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
