Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts processing technology, and in particular to an integrated punching and bending mold for motorcycle parts. Background Technology

[0002] In the manufacturing of motorcycle parts, punching and bending are two common and critical processes. Traditional production methods typically use separate single-machine dies, where punching is first completed on one stamping machine, and then operators transfer the semi-finished product to another bending machine for bending.

[0003] This production method has significant drawbacks: First, multiple clamping and positioning operations are not only inefficient and severely impact production cycle time, but also accumulate errors due to positioning datum conversion, making it difficult to guarantee the relative positional accuracy of punching positions and bending shapes, resulting in poor product consistency. Second, the high-intensity manual handling and frequent operations pose safety hazards and place high demands on operator skills. Furthermore, metal sheets are prone to slight warping during transportation or previous processes; if directly fed into the mold, this can affect processing quality and even damage the equipment.

[0004] Currently, although some integrated equipment attempts to combine multiple processes, they often fall short in terms of feeding accuracy, sheet metal pretreatment, and coordinated control of complex movements, making it difficult to achieve efficient and high-precision automated continuous production. Therefore, the industry urgently needs an automated solution that integrates leveling, precise feeding, punching, and bending, while ensuring high precision and stability. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an integrated punching and bending mold for motorcycle parts.

[0006] The technical solution of this utility model is: a punching and bending integrated mold for motorcycle parts, including a frame, a mounting seat on the frame, a lower mold seat on the mounting seat, an upper mold seat adapted to the lower mold seat that is slidably mounted on the frame, and a drive component A for driving the upper mold seat to rise or fall on the frame. The conveyor belt is mounted on the frame and located at the feed end of the lower die holder. The upper surface of the conveyor belt is flush with the upper surface of the lower die holder. The pushing mechanism is mounted on the frame. In operation, the pushing mechanism works with the conveyor belt to push the metal sheet downwards onto the die base at a fixed distance. And a leveling mechanism, which is set on the frame and located at the end of the pushing mechanism away from the lower mold base. The leveling mechanism levels the metal sheet in the working state.

[0007] Preferably, the mounting base is provided with an upward-opening inclined groove, the bottom surface of the inclined groove is provided with a telescopic rod, and the bottom surface of the inclined groove is provided with a tensioning component. The lower mold base is provided with a cutting groove communicating with the inclined groove, and an inclined platform that slides along its height direction is provided in the cutting groove. The inclined platform is connected to the movable ends of the telescopic rod and the tensioning component. A forming mold base is provided on the inclined platform, and a through hole communicating with the inclined groove is provided on the forming mold base.

[0008] Preferably, the upper mold base is provided with a downward-facing groove, the bottom surface of the upper mold base is adapted to the cutting groove, the groove is adapted to the forming mold base, and the bottom surface of the groove is provided with a punched column head adapted to the through hole.

[0009] Preferably, the pushing mechanism includes a slide, an anti-slip pressure plate, a drive assembly B, and a drive assembly C. The slide is mounted on the frame and slides along its length. A movable plate is slidably mounted on the slide. The anti-slip pressure plate is connected to the bottom surface of the movable plate. The drive assembly B is mounted on the slide and drives the movable plate to rise or fall. The drive assembly C is mounted on the frame and drives the slide to move away from or closer to the lower mold base.

[0010] Preferably, a number of guide rollers are spaced apart on the frame to support the upper load-bearing section of the conveyor belt.

[0011] Preferably, the leveling mechanism includes support rollers, pressure rollers, and drive assembly D. The support rollers include multiple rollers and are spaced apart at the feed end of the frame. The top of the support rollers is on the same plane as the upper surface of the conveyor belt. A U-shaped plate with its opening facing downward is slidably arranged on the frame above the support rollers. Multiple pressure rollers are spaced apart and rotatably arranged on the U-shaped plate. Each pressure roller is located above the support roller on its corresponding side. The drive assembly D is arranged on the frame and drives the U-shaped plate to rise or fall.

[0012] Preferably, a positioning mechanism is also provided on the frame between the conveyor belt and the leveling mechanism. The positioning mechanism includes a locking block and a drive component E. The two locking blocks are spaced apart and slidably arranged on the frame. Both sets of drive components E are arranged on the frame. When the machine is in the working state, the drive component E drives the corresponding locking block to slide along the conveying direction perpendicular to the metal plate.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: By integrating leveling, fixed-distance feeding, punching, and bending functions into a single station, intermediate transfer links are eliminated, significantly improving production efficiency and reducing labor costs and intensity. A linear module driven by a servo motor and ball screw is used for pushing, coupled with a precision guiding mechanism, achieving millimeter-level precise spacing feeding of metal sheets. This fundamentally ensures the relative accuracy of the punching and bending positions, guaranteeing product consistency and high quality. A unique design combining a slant groove, slant platform, and tensioning components, along with the downward pressing action of the upper die base, cleverly completes punching and bending actions continuously under a single vertical drive. The structure is compact, the power source is singular, and the operation is smooth and reliable, effectively reducing equipment complexity and manufacturing costs. The leveling mechanism pre-levels the sheet metal at the feeding end, avoiding processing defects, increased scrap rates, or die damage caused by uneven sheet metal, improving the stability of the entire system and the processing yield. Finally, by integrating a PLC and HMI human-machine interface, full-process automated control and convenient operation are achieved, making the equipment highly intelligent and easily integrated into modern production lines.

[0016] Example 1, as Figures 1-5As shown, the present invention proposes an integrated punching and bending mold for motorcycle parts, comprising a frame 1, a conveyor belt 11, a pushing mechanism 12, and a leveling mechanism. A mounting base 2 is provided on the frame 1, and a lower mold base 4 is provided on the mounting base 2. An upward-opening inclined groove 201 is provided on the mounting base 2. A telescopic rod 3 is vertically upward-facing on the bottom surface of the inclined groove 201, and a tensioning component 7 is vertically upward-facing on the bottom surface of the inclined groove 201. A cutting groove 41 communicating with the inclined groove 201 is provided on the lower mold base 4. An inclined platform 5 sliding along its height direction is provided within the cutting groove 41. The inclined platform 5 is connected to the movable ends of the telescopic rod 3 and the tensioning component 7. Preferably, the tensioning component 7 consists of two permanent magnets, which are respectively connected to the bottom surface of the inclined groove 201 and the bottom surface of the inclined platform 5. The magnetic poles of the two permanent magnets are the same at their closest ends. A forming mold base 6 is provided on the inclined platform 5, and a through hole 61 communicating with the inclined groove 201 is provided on the forming mold base 6. A slide carriage 8 is slidably mounted on the frame 1. An upper mold base 9, adapted to the lower mold base 4, is mounted on the bottom surface of the slide carriage 8. A downward-facing groove 91 is provided on the upper mold base 9. The bottom surface of the upper mold base 9 is adapted to the cutting groove 41. The groove 91 is adapted to the forming mold base 6. A punched protrusion 92, adapted to the through hole 61, is provided on the bottom surface of the groove 91. A drive assembly A is mounted on the frame 1 to drive the upper mold base 9 to rise or fall. The drive assembly A includes, but is not limited to, a servo electric cylinder A10. The body of the servo electric cylinder A10 is mounted on the frame 1, and its output end is connected to the slide carriage 8. A conveyor belt 11 is mounted on the frame 1 and located at the feed end of the lower mold base 4. The upper end face of the conveyor belt 11 is flush with the upper end face of the lower mold base 4. Several guide rollers are spaced apart on the frame 1 to support the upper load-bearing section of the conveyor belt 11.

[0017] The pushing mechanism 12 is mounted on the frame 1. The pushing mechanism 12 includes a slide 121, an anti-slip pressure plate 123, a driving assembly B, and a driving assembly C. The slide 121 is mounted on the frame 1 and slides along its length. A movable plate 122 is slidably mounted on the slide 121. The anti-slip pressure plate 123 is connected to the bottom surface of the movable plate 122. The driving assembly B includes, but is not limited to, a servo electric cylinder B124. The body of the servo electric cylinder B124 is mounted on the slide 121, and the output end of the servo electric cylinder B124 is connected to the movable plate 122. In operation, cylinder B124 drives the movable plate 122 to rise or fall; the drive assembly C includes, but is not limited to, the linear module 125. The body of the linear module 125 is mounted on the frame 1. The output end of the linear module 125 is connected to the slide 121. The driver of the linear module 125 adopts a servo motor + ball screw combination structure. In operation, the linear module 125 drives the slide 121 to move away from or closer to the lower mold base 4. In operation, the pushing mechanism 12, in conjunction with the conveyor belt 11, pushes the metal sheet onto the lower mold base 4 at a fixed distance.

[0018] The leveling mechanism is mounted on the frame 1 and located at the end of the pushing mechanism 12 away from the lower mold base 4. The leveling mechanism includes support rollers 13, pressure rollers 18, and a drive assembly D. Multiple support rollers 13 are spaced apart at the feeding end of the frame 1. The top of the support rollers 13 is on the same plane as the upper surface of the conveyor belt 11. A U-shaped plate 17 with its opening facing downward is slidably mounted on the frame 1 above the support rollers 13. Multiple pressure rollers 18 are spaced apart and rotatably mounted on the U-shaped plate 17. Each pressure roller 18 is located above the support rollers 13 on the corresponding side. The drive assembly D includes, but is not limited to, a servo electric cylinder C19. The body of the servo electric cylinder C19 is mounted on the frame 1. The output end of the servo electric cylinder C19 is connected to the U-shaped plate 17. In the working state, the servo electric cylinder C19 drives the U-shaped plate 17 to rise or fall. In the working state, the leveling mechanism levels the metal sheet.

[0019] It should be noted that this technical solution also includes a control panel, which uses a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly interface, allowing them to easily issue various commands by touching the screen.

[0020] In this embodiment, the sheet metal is first leveled. The end of the metal sheet is pulled from the unwinding machine and placed on the support roller 13. After the equipment is started, the servo electric cylinder C19 drives the U-shaped plate 17 to descend, causing the pressure roller 18 mounted on it to press the sheet metal against the corresponding support roller 13, pushing the metal sheet forward until it falls onto the conveyor belt 11. As the sheet metal passes between the pressure roller 18 and the support roller 13, the combined action of the support roller 13 and the pressure roller 18 utilizes multi-point pressure to eliminate internal stress and warping, ensuring that the sheet metal entering the mold is flat.

[0021] Next, the material is conveyed at a fixed distance. The leveled sheet is fed into the conveyor belt 11, whose upper surface is flush with the upper surface of the lower mold base 4, providing stable support for the sheet. The pushing mechanism then begins operation: the servo electric cylinder B124 drives the movable plate 122 to descend, causing the anti-slip pressure plate 123 to press the sheet against the material; subsequently, the linear module 125 starts, its servo motor driving the ball screw to precisely control the slide 121, along with the pressed sheet, to move a predetermined distance toward the lower mold base 4, completing one fixed-distance push. Afterward, the anti-slip pressure plate 123 is raised, and the linear module 125 drives the slide 121 back to its original position, ready for the next push. This cycle repeats, gradually and precisely pushing the sheet to the designated processing position on the lower mold base 4.

[0022] Then, the punching and bending process is performed. After the sheet metal is conveyed to the predetermined position, the servo electric cylinder A10 of the drive assembly A is activated, driving the slide 8 and upper die base 9 to descend as a whole. During this stage, the tensioning assembly 7 applies an upward tension force to the inclined platform 5, keeping it horizontal and stable. As the upper die base 9 continues to descend, its bottom edge, in conjunction with the cutting groove 41, cuts a standard metal plate from the original sheet metal. The metal plate continues to descend with the inclined platform 5, which stops descending after landing on the outer cylinder of the telescopic rod 3. At this time, the groove 91, in conjunction with the forming die 6, bends the area of ​​the metal plate to be bent while simultaneously cutting off the excess portion. Simultaneously, the punching head 92, in conjunction with the through hole 61, punches holes in the workpiece. After the punching and bending process is completed, the upper die base 9 slides upward and resets, and the inclined platform 5, under tension, slides upward and resets, causing the top of the formed workpiece to extend beyond the upper surface of the lower die base 9. During subsequent movement of the pushed metal plate, the formed part is automatically ejected, while the cut-off excess portion is directly discharged along the inclined platform 5 and the inclined groove 201, ready to enter the next work cycle.

[0023] Example 2, as Figure 1 and Figure 6 As shown, the present invention proposes a punching and bending integrated mold for motorcycle parts. Compared with Embodiment 1, a positioning mechanism is also provided on the frame 1 between the conveyor belt 11 and the leveling mechanism. The positioning mechanism includes a locking block 20 and a drive assembly E. Two locking blocks 20 are spaced apart and slidably disposed on the frame 1. Guide wheels 21 are provided on the sides of the locking blocks 20 that are close to each other, and the guide wheels 21 are in contact with the side of the metal plate. Two sets of drive assemblies E are disposed on the frame 1. The drive assembly E includes, but is not limited to, a lead screw 22, a worm gear 23 and a worm 24. The lead screw 22 is rotatably connected to the frame 1. A guide rod parallel to the lead screw 22 is provided on the frame 1. The locking block 20 is threadedly connected to the lead screw 22 and slidably connected to the guide rod. The worm gear 23 is coaxially connected to the lead screw 22. The worm 24 is rotatably connected to the frame 1 and meshes with the worm gear 23. A crank is provided at one end of the worm 24 that extends out of the frame 1, so as to drive the locking block 20 on the corresponding side to slide in the conveying direction perpendicular to the metal plate by rotating the crank.

[0024] It should be noted that the exposed section of the lead screw 22 is fitted with a lead screw protective sleeve, and the worm gear 23 and worm 24 are fitted with protective covers.

[0025] In this embodiment, rotating the crank drives the lead screw 22 to rotate, which in turn drives the locking block 20 to slide. The guide wheel 21 is used to limit the side of the metal plate to prevent the metal plate from shifting during the pushing process, thereby ensuring that the specifications of the parts after punching and bending are uniform.

[0026] Example 3, as Figure 1 and Figure 5As shown, the present invention proposes an integrated punching and bending mold for motorcycle parts. Compared with Embodiment 1, a ratchet 14 is coaxially arranged on the roller shaft of the support roller 13, and a spring rod 15 is arranged on the frame 1. The movable end of the spring rod 15 is connected to the ratchet 16. The ratchet 16 and the ratchet tooth 14 engage in one direction. Under the limitation of the ratchet tooth, the support roller 13 only rotates when the metal plate moves towards the lower mold base 2.

[0027] In this embodiment, the ratchet and tooth structure, together with the pressure roller 18, can prevent the metal plate from slipping off at the front end and avoid it from sliding back under the gravity of the rear end. This structure can further improve the accuracy of each push of the metal plate.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
