Description

[0001] This invention relates to the field of metal mudguard forming technology, and more specifically, to a composite forming machine for motorcycle mudguards. Background Technology

[0002] Motorcycle mudguards are plate-type protective structures installed behind the outer frame of a motorcycle wheel. They are mainly used to block mud, water and debris splashed up during driving, preventing them from splashing onto the rider, body parts and engine. They also protect the body, reduce wind noise, and improve the overall appearance of the motorcycle.

[0003] In terms of materials, motorcycle mudguards are currently mainly divided into plastic and metal. Although plastic mudguards are the most widely used due to their low cost and high cost-effectiveness, metal mudguards have irreplaceable advantages over plastic mudguards when facing different needs, such as users with customization and off-road requirements. Metal mudguards have high structural strength and excellent impact resistance, and are not prone to breakage or damage under off-road, heavy load, and complex road conditions. For example, plastic mudguards are likely to be punctured on gravel roads. Their service life is several times that of plastic mudguards. They have a unique aesthetic and texture, providing a quality that plastic cannot match. Moreover, they are repairable. If deformation occurs, metal mudguards can be repaired, while plastic mudguards usually have to be replaced as a whole once damaged.

[0004] After metal mudguards are stamped, due to factors such as die wear, material springback, fluctuations in stamping parameters, or bumps during transportation, some mudguards inevitably have defects such as local dents, bulges, edge warping, curvature deviations, and twisting deformation. For these parts, even though they have been stamped, they can only be considered finalized after these defects are eliminated. At this point, it is necessary to apply specific mechanical external force to reshape the mudguards, thereby eliminating these defects, restoring the geometric shape and dimensional accuracy required by the design, and finally making these defective mudguards into finalized mudguards. Besides the most common manual hammering shaping, the most common method is to use ordinary stamping presses to eliminate defects one by one. Therefore, the complete shaping of a metal mudguard often requires multiple processes on multiple presses with different specializations. The shaping operation is very cumbersome and time-consuming, which seriously affects the efficiency of mass production. Moreover, mudguards are curved parts, unlike conventional plate-shaped or geometrically flat parts. Therefore, the clamping and fixing during shaping is more difficult. In addition, multiple clamping processes not only take a long time, but also easily cause additional damage to the mudguard. Furthermore, the use of equipment that is not well-suited for mudguard shaping often relies on operator experience to achieve the shaping accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a composite shaping machine for motorcycle mudguards to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides a motorcycle fender composite shaping machine, comprising a machine base and a vertical base wall, wherein the vertical base wall is mounted on the machine base, a panel is mounted on the vertical base wall, and a pressure straightener is provided on the panel; After the pressure straightener is activated, it can fit the motorcycle fender into a clamp to cover the motorcycle fender on both sides and apply pressure as a whole. The pressure straightener adapts and positions the motorcycle mudguard and applies localized strong pressure to the motorcycle mudguard.

[0007] Furthermore, the pressure straightener includes several vertically mounted sliding grooves on the panel, an upper arm and a lower arm slidably mounted in the several sliding grooves respectively, the upper arm and the lower arm being arranged opposite to each other, two sets of hydraulic cylinders mounted on the panel, the output ends of the two sets of hydraulic cylinders being connected to the back of the upper arm and the lower arm respectively, and two sets of clamping ends respectively mounted on the upper arm and the lower arm, the two sets of clamping ends being one above the other and corresponding to each other; The motorcycle mudguard can be fitted and clipped onto the clamping end located below; After driving the two sets of hydraulic cylinders, the two sets of clamping ends are continuously brought together in the center. At this time, the two sets of clamping ends can clamp the motorcycle mudguard from both the inside and outside.

[0008] Furthermore, the clamping end includes an arc-shaped rod mounted on the upper arm, a plurality of handles rotatably mounted on the arc-shaped rod, and a plurality of contoured clamping plates respectively connected to the plurality of handles; When several of the aforementioned handles are in the same direction, several of the aforementioned conforming clamping pieces are spliced ​​together in sequence, and when the conforming clamping pieces at the two sets of clamping ends are spliced ​​together, their shapes respectively match the inner and outer sides of the motorcycle mudguard; There is a damping force between the handle and the arc-shaped rod.

[0009] Furthermore, several of the aforementioned conforming clamping plates have notches on their sides, and each notch contains an electromagnet block, which is connected to an external power source. When several of the conforming clamping pieces are spliced ​​together, the electromagnet block on the side of each conforming clamping piece is in contact with the adjacent conforming clamping piece.

[0010] Furthermore, a sliding plate is movably disposed on the panel, and the slide groove connected to the lower arm and a set of hydraulic cylinders are installed on the sliding plate. When the sliding plate is moved, the lower arm is carried away from the motorcycle fender. Electromagnet blocks are embedded in the bottom of several of the contoured clamping plates located at the upper clamping end. The electromagnet blocks are connected to an external power source. When the two sets of clamping ends clamp the motorcycle mudguard, the electromagnet blocks at the bottom of the several contoured clamping plates located at the upper end are in contact with the motorcycle mudguard. An extension platform is mounted on the sliding plate surface, and a movable seat is provided on the extension platform. An impact cylinder is mounted on the movable seat, and a hammer is mounted on the output end of the impact cylinder. When the sliding plate surface is moved to move the lower arm away from the motorcycle fender, the impact cylinder moves to below the motorcycle fender, and the hammer is aligned upward with the motorcycle fender.

[0011] Furthermore, the movable seat includes a swivel ball mounted on the extended platform, a telescopic cylinder connected to the swivel ball, a supply plate connected to the top of the telescopic cylinder and bent to extend to the side of the telescopic cylinder, an impact cylinder mounted on the supply plate, and a handle connected to the supply plate and surrounding the impact cylinder.

[0012] Furthermore, the panel is rotatably mounted on the vertical base wall, and a rotating shaft is connected to the center of the back of the panel. The rotating shaft rotates backward through the vertical base wall via a bearing. A motor is mounted on the back of the vertical base wall, and gears are mounted on both the output shaft of the motor and the rotating shaft. The two gears mesh.

[0013] Furthermore, the machine base is provided with a contouring download platform and a suspension plate. A flat-headed pin is slidably inserted into the suspension plate. A spring is provided between the middle of the flat-headed pin and the bottom surface of the suspension plate. An upper closing plate is connected to the end of the flat-headed pin. The upper closing plate overlaps with the contouring download platform. After the motorcycle mudguard is placed between the upper fitting plate and the contouring download platform, the upper fitting plate and the contouring download platform are in contact with the motorcycle mudguard.

[0014] Furthermore, rotating latches are installed on both sides of the sliding plate and on the panel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention places a defective motorcycle fender into a standard shaping space. First, it performs continuous overall clamping and straightening, eliminating localized depressions, protrusions, and especially edge warping, curvature deviations, and twisting deformations during this process. This brings the motorcycle fender's geometry and dimensions closer to standard. Then, it performs multiple targeted local shaping and straightening processes using two differentiated methods to further eliminate defects, effectively ensuring the restoration of the defective motorcycle fender to its standard geometric shape and dimensional accuracy, thus completing the repair of the defective fender. The final shaping of motorcycle mudguards is achieved on this machine. The entire shaping process can be completed on the machine, eliminating the need for multiple steps at different locations. This greatly simplifies the shaping process, effectively improving efficiency. Furthermore, all fixing steps during the shaping process are tailored to the curved surface of the motorcycle mudguard, ensuring both effective fixing and a good fit to its unique shape. This not only makes operation convenient and quick but also avoids secondary damage to the mudguard caused by clamping. The high degree of adaptability allows operators to perform shaping operations more stably and precisely, effectively guaranteeing shaping accuracy. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] Please see Figures 1-3 A composite shaping machine for motorcycle mudguards includes a machine base 1 and a vertical base wall 2. The vertical base wall 2 is mounted on the machine base 1, and a panel 3 is mounted on the vertical base wall 2. A pressure straightener 4 is provided on the panel 3. After the pressure straightener 4 is activated, it clamps and fits the motorcycle fender 5 together, covering both sides of the fender 5 and applying pressure as a whole. The pressure straightener 4 adapts and positions the motorcycle fender 5 and applies localized strong pressure to the fender 5. The defective motorcycle fender 5 is placed into the standard shaping space formed by the pressure straightener 4, and first, it undergoes continuous overall clamping and straightening. During this clamping and straightening process, defects such as localized depressions and protrusions on the motorcycle fender 5, especially edge warping, curvature deviations, and twisting deformations, are eliminated, bringing the geometry and dimensions of the motorcycle fender 5 closer to standard. Subsequently, the motorcycle fender 5 undergoes multiple localized targeted shaping and straightening processes in two differentiated ways to further eliminate defects on the motorcycle fender 5. This machine effectively ensures the restoration of the standard geometry and dimensional accuracy of the defective motorcycle fender 5, completing the final forming of the defective motorcycle fender 5. The entire forming process can be completed on this machine, eliminating the need for multiple steps at different locations, thus greatly simplifying the forming operation and effectively improving forming efficiency. Furthermore, all fixing steps during the forming process are tailored to the characteristics of the curved surface of the motorcycle fender 5, providing a secure fit while also adapting well to the special shape of the motorcycle fender 5. This not only makes the operation convenient and quick but also avoids secondary damage to the motorcycle fender 5 caused by clamping and fixing. The high degree of adaptability allows operators to perform the forming operation more stably and accurately, effectively guaranteeing the forming precision.

[0021] Optionally, the pressure straightener 4 includes several slide grooves 41 vertically mounted on the panel 3, an upper arm 42 and a lower arm 43 slidably mounted in the slide grooves 41 respectively, the upper arm 42 and the lower arm 43 being arranged opposite to each other, two sets of hydraulic cylinders 44 mounted on the panel 3, the output ends of the two sets of hydraulic cylinders 44 being connected to the back of the upper arm 42 and the lower arm 43 respectively, and two sets of clamping ends 45 respectively mounted on the upper arm 42 and the lower arm 43, the two sets of clamping ends 45 being one above the other and corresponding to each other; The motorcycle mudguard 5 can be fitted and clipped onto the clamping end 45 located below; After driving the two sets of hydraulic cylinders 44, the two sets of clamping ends 45 continuously close towards the center. At this time, the two sets of clamping ends 45 can clamp the motorcycle mudguard 5 from both the inside and outside. The two sets of clamping ends 45 are the standard shape of the motorcycle mudguard 5. During shaping, the motorcycle mudguard 5 is first clamped onto the lower clamping end 45, and then the two sets of hydraulic cylinders 44 are driven. The two sets of hydraulic cylinders 44 push the two sets of clamping ends 45 continuously close towards the center through the upper arm 42 and the lower arm 43 until the motorcycle mudguard 5 is clamped. At this time, the two sets of clamping ends 45 cover and clamp the motorcycle mudguard 5 from both the inside and outside. The lower clamping end 45 presses against the inner side of the motorcycle mudguard 5, while the upper clamping end 45 presses against the surface of the motorcycle mudguard 5. Under the continuous force and holding of the two sets of hydraulic cylinders 44, the motorcycle mudguard 5 is corrected as a whole for a certain period of time. During this process, the parts of the motorcycle mudguard 5 whose geometry does not match the two sets of clamping ends 45 will be forcibly changed, thereby eliminating the defects such as local depressions, protrusions, especially edge warping, curvature deviation, and twisting deformation on the motorcycle mudguard 5, so that the geometry and size of the motorcycle mudguard 5 tend to be standard.

[0022] Optionally, the clamping end 45 includes an arc-shaped rod 451 mounted on the upper arm 42, a plurality of handles 452 rotatably mounted on the arc-shaped rod 451, and a plurality of contoured clamping plates 453 respectively connected to the plurality of handles 452. Another set of clamping ends 45 is mounted on the lower arm 43 in the same manner. When several handles 452 are aligned in the same direction, several contoured clamping plates 453 are sequentially spliced ​​together. When the contoured clamping plates 453 of the two sets of clamping ends 45 are spliced ​​together, their shapes respectively match the inner and outer sides of the motorcycle mudguard 5. When all the upper contoured clamping plates 453 are spliced ​​together, they match the surface of the motorcycle mudguard 5. When all the lower contoured clamping plates 453 are spliced ​​together, they fit against the inner side of the motorcycle mudguard 5. When the hydraulic cylinder 44 is activated, it pushes all the arc-shaped rods 451, handles 452, and contoured clamping plates 453 to move, straight... After pressing the conformal clamping piece 453 onto the motorcycle fender 5 and completing the overall clamping and correction, observe which parts of the motorcycle fender 5 still have defects, especially local dents and protrusions. Then, rotate the corresponding lower handle 452 to remove the corresponding conformal clamping piece 453, and simultaneously rotate the corresponding upper handle 452. At this point, clamp the motorcycle fender 5 onto the lower conformal clamping piece 453. The defective parts of the motorcycle fender 5 will then be freed up, and the defective parts will be... Above the mudguard, there is still a contoured clamping plate 453. Then, the lower set of hydraulic cylinders 44 remains stationary while the upper set of hydraulic cylinders 44 is activated, pushing the upper contoured clamping plate 453 downwards towards the lower motorcycle mudguard 5. The upper contoured clamping plate 453 applies strong pressure to the defective area on the motorcycle mudguard 5. Since the area below the defect is hollow, the strong pressure from the upper contoured clamping plate 453 causes deformation, thus pressing down the protruding part and achieving [the desired effect]. The defects are eliminated by the cooperation of the upper and lower contour clamping plates 453. While maintaining support for the motorcycle fender 5, a single strong pressure is used to simultaneously complete the shaping and correction of multiple local positions on the motorcycle fender 5, ensuring efficiency. The overall splicing shape of the lower contour clamping plate 453 matches the shape of the motorcycle fender 5. Therefore, even if there are a few less lower contour clamping plates 453, they can still stably and perfectly support the motorcycle fender 5, ensuring the accuracy of the strong pressure correction and preventing secondary damage to the motorcycle fender 5. There is a damping force between the handle 452 and the arc-shaped rod 451, that is, there is a large friction between the two. A certain amount of force needs to be applied to rotate the handle 452 and cause the corresponding conforming pressure clamp 453 to deflect. This ensures the stability and effectiveness of the motorcycle mudguard 5 when the conforming pressure clamp 453 is used to forcefully press and correct it, so as to prevent the handle 452 from rotating unnecessarily and affecting the shaping and correction or even causing a safety accident.

[0023] Optionally, several contour clamping plates 453 have notches on their sides, and each notch is fitted with an electromagnet block, which is connected to an external power source. When several contour clamping pieces 453 are spliced ​​together, the electromagnet blocks on the side of each contour clamping piece 453 are in contact with the adjacent contour clamping pieces 453. When all the handles 452 are adjusted to the same direction so that the upper and lower contour clamping pieces 453 are precisely spliced ​​together to correct the motorcycle mudguard 5 as a whole, the external power supply is turned on so that the electromagnet blocks are energized to generate attraction force, which attracts and tightens the adjacent contour clamping pieces 453, thereby further ensuring the firm and stable splicing state of the upper and lower contour clamping pieces 453, ensuring the stability and effectiveness of the strong pressure correction of the motorcycle mudguard 5, and further preventing accidents when clamping the motorcycle mudguard 5.

[0024] Optionally, a sliding plate 31 is movably provided on the panel 3. A slide groove 41 connected to the lower arm 43 and a set of hydraulic cylinders 44 are installed on the sliding plate 31. When the sliding plate 31 is moved, the lower arm 43 is carried away from the motorcycle mudguard 5. Electromagnet blocks are embedded in the bottom of several contoured clamping plates 453 located on the upper clamping end 45. The electromagnet blocks are connected to an external power source. When the two sets of clamping ends 45 clamp the motorcycle mudguard 5, the electromagnet blocks at the bottom of the several contoured clamping plates 453 located on the upper side are in contact with the motorcycle mudguard 5. An extension platform 6 is mounted on the sliding plate surface 31. A movable seat 7 is provided on the extension platform 6. An impact cylinder 8 is mounted on the movable seat 7. A hammer 9 is mounted on the output end of the impact cylinder 8. When the sliding plate surface 31 is moved so that the lower arm 43 is away from the motorcycle fender 5, the impact cylinder 8 moves to below the motorcycle fender 5, and the hammer 9 is aligned upwards with the motorcycle fender 5. The impact cylinder 8 is an existing special-function cylinder with a fast impact speed. After the local shaping and correction of the motorcycle fender 5 is completed by the contour clamping plate 453, the motorcycle fender 5 is held in place by the contour clamping plate 453 below. In state 53, reset the upper hydraulic cylinder 44, moving the upper conforming clamping plate 453 away from the motorcycle fender 5 and observe which parts of the motorcycle fender 5 still have defects, especially local dents and protrusions. Then, rotate the corresponding upper handle 452 to move the corresponding conforming clamping plate 453 away. Then, restart the upper hydraulic cylinder 44 to press the upper conforming clamping plate 453 back onto the motorcycle fender 5. At this time, the upper part of the motorcycle fender 5 with defects is now freed up. Then, connect the external power supply to make the electromagnetic... When the iron block is energized, it firmly holds the motorcycle fender 5 in place. Then, the lower hydraulic cylinder 44 is reset, and the sliding plate 31 is pulled horizontally, causing the lower conforming clamping plate 453 to completely move away from the motorcycle fender 5. The impact cylinder 8 is then moved to the underside of the motorcycle fender 5. Using the impact cylinder 8 as a shaping tool, the hammer head 9 strikes the motorcycle fender 5 after the impact cylinder 8 is activated to eliminate protrusions and other defects. The impact force of the impact cylinder 8 is carefully controlled, and the defective areas are shaped by repeated, small-amplitude hammering, avoiding excessive force that could damage the motorcycle fender 5. Secondary damage is avoided; relying on the conformal clamping piece 453 that fits into the motorcycle mudguard 5, and with the attraction of the electromagnet block, the motorcycle mudguard 5 is fixed in place, ensuring that it can be shaped. It is custom-fitted to the characteristics of the motorcycle mudguard 5 with its curved surface. While having a fixing effect, it can also adapt well to the special shape of the motorcycle mudguard 5. It is not only convenient and quick to operate, but also avoids secondary damage to the motorcycle mudguard 5 caused by clamping and fixing. The high degree of adaptability allows the operator to perform shaping operations more stably and accurately, and the shaping accuracy is effectively guaranteed.

[0025] Optionally, the movable seat 7 includes a universal ball 71 mounted on the extension platform 6, a telescopic cylinder 72 connected to the universal ball 71, a feeding plate 73 connected to the top of the telescopic cylinder 72 and bent to extend to the side of the telescopic cylinder 72, an impact cylinder 8 mounted on the feeding plate 73, and a handle 74 connected to the feeding plate 73 and surrounding the impact cylinder 8. With the support of the universal ball 71, the telescopic cylinder 72 can swing flexibly, and with the support of the telescopic cylinder 72, the feeding plate 73 can rise or fall. Therefore, when the operator holds the handle 74 and starts the impact cylinder 8 to perform hammering and shaping, the hammer head 9 can be flexibly aligned with the defective part on the motorcycle fender 5, ensuring that the defective part can be accurately found and shaped, thereby effectively ensuring that the standard geometric shape and dimensional accuracy of the defective motorcycle fender 5 can be restored, and the final forming of the defective motorcycle fender 5 can be completed.

[0026] Optionally, the panel 3 is rotatably mounted on the vertical base wall 2. A rotating shaft 10 is connected to the center of the back of the panel 3. The rotating shaft 10 rotates backward through the vertical base wall 2 via a bearing. A motor 11 is mounted on the back of the vertical base wall 2. Gears 12 are mounted on both the output shaft of the motor 11 and the rotating shaft 10. The two gears 12 mesh. When precisely shaping the motorcycle mudguard 5, while keeping the motorcycle mudguard 5 fixed, the motor 11 is started. Through the meshing of the two gears 12 and the rotating shaft 10, the panel 3 is driven to slowly rotate on the vertical base wall 2, thereby adjusting the angle of the motorcycle mudguard 5 so that its inner side faces the side, top, etc. This allows the operator to better observe the defective parts on the motorcycle mudguard 5 and perform shaping operations more conveniently, further ensuring more stable and precise shaping operations.

[0027] Optionally, the machine base 1 is provided with a contouring download platform 13 and a suspension plate 14. A flat-headed pin 15 is slidably inserted on the suspension plate 14. A spring 16 is provided between the middle of the flat-headed pin 15 and the bottom surface of the suspension plate 14. An upper closing plate 17 is connected to the end of the flat-headed pin 15. The upper closing plate 17 overlaps with the contouring download platform 13. Heating elements, such as heating wires, are arranged inside the upper closing plate 17 and the contouring download platform 13. After placing the motorcycle fender 5 between the upper fitting piece 17 and the contouring platform 13, the upper fitting piece 17 and the contouring platform 13 are in contact with the motorcycle fender 5. During shaping, the next motorcycle fender 5 to be shaped can be placed on the contouring platform 13. The flat-head pin 15 is released, and the spring 16 rebounds, pulling the flat-head pin 15 down, thereby pressing the upper fitting piece 17 onto the motorcycle fender 5. The motorcycle fender 5 is pressed between the upper fitting piece 17 and the contouring platform 13, and the power supply to the heating element is turned on, so that it begins to heat up. The heat is continuously transferred to the motorcycle fender 5 in the middle through the upper fitting piece 17 and the contouring platform 13, heating it up to increase the temperature of the motorcycle fender 5 and achieve preheating, thereby improving the plasticity of the motorcycle fender 5, reducing the difficulty of subsequent shaping to a certain extent, and making it easier to be corrected and shaped, thus obtaining a better shaping effect.

[0028] Optionally, rotating latches 18 are installed on both sides of the sliding plate 31 and on the panel 3. When using the contour clamping plate 453, the left rotating latch 18 is used to fix the sliding plate 31. When using the impact cylinder 8, the right rotating latch 18 is used to fix the sliding plate 31, ensuring the normal operation and use of the corresponding process functions, while also taking into account simplicity.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
