Description

Technical Field

[0001] The present invention belongs to the technical field of fender processing: specifically, it relates to a processing device for fenders of new energy vehicles. Background Art

[0002] A fender is a plate-like structure installed behind the outer frame of a wheel. Fenders are usually installed behind the wheels of a vehicle. Installing a fender can effectively prevent flying stones and gravel from damaging the paint surface of the vehicle body. When installed behind the tires of a car, it effectively protects the vehicle body from the impact of sand, gravel, and debris, and can prevent mud and water from damaging the bottom components.

[0003] Some solutions have also been proposed in the prior art: for example, a patent with the publication number CN115213455A discloses a processing technology for automobile fenders, including a clamping base and a rotating disk. A polygonal rotating disk is rotatably arranged above the clamping base. A third rotating base is fixedly arranged on the rotating disk, and a first rotating base is rotatably arranged on the third rotating base. A clamping main board is fixedly arranged on the bottom surface of the first rotating base. A plurality of telescopic bases are arranged on both sides of the outer end face of the clamping main board. Through the linkage design of the clamping main board and the first spring, the device can effectively clamp the automobile fender with an arc surface. By setting rib plates, the automobile fender can be pulled apart to both sides during the clamping process, making subsequent hole punching and cleaning more convenient.

[0004] Generally, the production of fenders is carried out by stamping a steel plate with a stamping machine to cause plastic deformation of the raw material steel plate to form a fender. During the stamping process of the steel plate, if there are excess waste materials or burrs on the surface of the steel plate, it is easy to cause scratches, wear, or even chipping on the surface of the stamping die during stamping, affecting the service life of the die and the stamping quality. Moreover, the material flow is uneven and the pressure distribution is uneven, reducing the die closing accuracy and stamping stability.

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Such as Figures 1 to 9As shown in the figure, the present invention provides a technical solution: a processing device for a fender of a new energy vehicle, including a processing table 1. A stamping table 2 is fixedly installed on the top of the processing table 1. The upper part of the stamping table 2 is used for placing the fender to be processed. A pair of hydraulic rods 3 are fixedly connected to the top of the processing table 1. A lifting plate 4 is fixedly connected between the tops of the two hydraulic rods 3. A stamping die 5 is fixedly connected below the lifting plate 4. The stamping die 5 is located directly above the stamping table 2. The top surface of the stamping table 2 is concave, and the bottom of the stamping die 5 is convex. A trimming component is arranged above the stamping table 2, and the trimming component is used for removing the residual waste on the surface of the fender. A material pushing component is arranged on the side of the stamping table 2, and the material pushing component is used for pushing out the stamped fender from the side of the stamping table 2 for blanking.

[0033] During operation: Flat steel plates are usually selected as raw materials for the fenders of new energy vehicles. These steel plates have good stamping performance and mechanical strength, and can meet the usage requirements of the fenders. When the device is in use, the pre-treated steel plate is placed directly above the stamping table 2. The hydraulic rod 3 drives the lifting plate 4 to descend. When the lifting plate 4 descends, it will drive the stamping die 5 to gradually move downward towards the steel plate. When the stamping die 5 applies pressure to the steel plate on the stamping table 2, the steel plate flows towards the concave surface of the female die under the extrusion of the male die and the female die. Due to the constraint of the female die, the steel plate is forced to form an arc-shaped inner surface consistent with the concave surface of the female die, thus forming an arc-shaped fender. And when the lifting plate 4 drives the stamping die 5 to press down, it will drive the trimming component to move. The trimming component scrapes off the excess waste or burrs on the surface of the steel plate, avoiding scratches, abrasions or even chipping on the surface of the stamping die 5 when the waste or burrs on the surface of the steel plate come into contact with the stamping die 5. The trimming component clears the waste in advance, which can effectively protect the surface of the stamping die 5, and the surface of the steel plate is smoother, the material flow is more uniform during stamping, and the pressure distribution applied by the stamping die 5 during pressing is more uniform, ensuring the closing accuracy of the die and improving the stamping stability. After the stamping die 5 stamps the steel plate and makes the steel plate stably formed, the stamping die 5 is lifted and reset by the hydraulic rod 3. During the rising process of the stamping die 5, it will synchronously drive the material pushing component to move. The material pushing component can push out the stamped arc-shaped fender from the side of the stamping table 2 for blanking, thus achieving the effect of rapid blanking, avoiding workpiece damage or safety hazards caused by manual operation, shortening the production cycle, improving the equipment utilization rate, and ensuring the consistency of the blanking position, providing a reliable guarantee for the efficient connection of subsequent processes.

[0034] As Figures 4 to 5As shown, the edge cleaning component includes two scraping blade plates 6. The bottoms of the two scraping blade plates 6 are both in contact with the top of the steel plate and are both located in the middle position above the steel plate. The adjacent sides of the two scraping blade plates 6 are in contact with each other. Transverse sliding seats 7 are arranged on both sides of the two scraping blade plates 6. The transverse sliding seats 7 are fixedly installed on the top of the processing table 1. Inner sliding blocks 8 are slidably connected to the inner walls of the transverse sliding seats 7. L-shaped plates 12 are fixedly connected to the tops of the two inner sliding blocks 8. Pushing components are arranged on both sides of the stamping die 5. The pushing components push the L-shaped plates 12, causing each inner sliding block 8 to slide along the inner wall of each transverse sliding seat 7 respectively.

[0035] During operation: When the stamping die 5 moves downward close to the steel plate, it will push the L-shaped plate 12 through the pushing component. When the L-shaped plate 12 is under the thrust, each inner sliding block 8 will slide along the inner wall of each transverse sliding seat 7 respectively. During the sliding process of each inner sliding block 8, the two scraping blade plates 6 will move away from each other. The bottoms of the two scraping blade plates 6 move along the top surface of the steel plate to scrape off the excess waste and burrs on the surface of the steel plate. When the two scraping blade plates 6 move away from each other, they will face the two sides of the stamping table 2. The excess waste and burrs will leave above the stamping table 2 and the steel plate, making the surface of the steel plate flat, thus avoiding the risk of the stamping die 5 being scratched by the excess waste and burrs and improving the stamping stability.

[0036] As Figures 3 to 4 shown, the pushing component includes a plurality of hinge parts 9. The plurality of hinge parts 9 are respectively fixedly installed on the side of the stamping die 5. Hinge connecting rods 10 are hinged to the inner walls of the hinge parts 9. Push wheels 11 are fixedly connected to the ends of the hinge connecting rods 10 far away from the hinge parts 9. The outer walls of the push wheels 11 are in contact with the outer walls of the L-shaped plates 12. Cross plates 13 are fixedly connected to the tops of the hinge parts 9. Torsion springs 14 are fixedly connected between the bottoms of the cross plates 13 and the sides of the hinge connecting rods 10.

[0037] During operation: When the stamping die 5 descends, the push wheel 11 first contacts the outer wall of the L-shaped plate 12. Since the L-shaped plate 12 is fixed, the push wheel 11 rotates around the axis of the hinge part 9 under the reaction force. When the push wheel 11 rotates, the hinge connecting rod 10 swings synchronously, converting the downward force of the die in the horizontal direction into a thrust on the L-shaped plate 12. The L-shaped plate 12 slides horizontally under the thrust, and its vertical section pushes the inner sliding block 8 to slide outward along the inner wall of the transverse sliding seat 7, triggering the unfolding action of the scraping blade plate 6. The rotation angle of the push wheel 11 is automatically adjusted with the descending stroke of the die to ensure that the L-shaped plate 12 obtains a stable thrust and avoid rigid impact. During the stamping process, the torsion spring 14 is compressed and deformed. After the stamping is completed, when the stamping die 5 rises, the torsion spring 14 releases its elastic potential energy, pushing the hinge connecting rod 10 to reset, and the push wheel 11 presses tightly against the L-shaped plate 12 again, preparing for the next stamping.

[0038] As Figures 5 to 6As shown in the figure, movable rods 15 are fixedly connected to the sides of the first inner slider 8. The outer walls of the movable rods 15 are slidably connected to the side walls of the transverse sliding seat 7. Limit platforms 17 are fixedly connected to the ends of the movable rods 15 away from the first inner slider 8. First return springs 16 are fixedly connected between the limit platforms 17 and the side surfaces of the transverse sliding seat 7. An anti-scraping assembly is arranged below the transverse sliding seat 7, and the anti-scraping assembly is used to clean the scraps adhered to the inclined surface of the scraping blade plate 6.

[0039] During operation: When the first inner slider 8 slides along the inner wall of the transverse sliding seat 7, it will push the movable rod 15 to slide on the side wall of the transverse sliding seat 7. When the movable rod 15 slides, it will stretch the first return spring 16. After stamping is completed, the first return spring 16 releases its elastic potential energy, pushing the movable rod 15 to reset, driving the first inner slider 8 and the scraping blade plate 6 to retract automatically, preparing for the next stamping; and when the scraping blade plate 6 scrapes the material, some waste materials or burrs will adhere to the inclined wall of the scraping blade plate 6 under the electrostatic effect. Through the arranged anti-scraping assembly, the scraps adhered to the inclined surface of the scraping blade plate 6 can be cleaned, facilitating the complete sorting and collection of the redundant waste materials and burrs.

[0040] As Figures 6 to 7 shown, the anti-scraping assembly includes two anti-scraping plates 18, which are respectively fixedly connected between the bottoms of the two transverse sliding seats 7. Movable blocks 19 are fixedly connected to both sides of the two scraping blade plates 6. The outer walls of the movable blocks 19 are slidably connected to an inclined sliding seat 20. The outer wall of the inclined sliding seat 20 is fixedly connected to one side of the first inner slider 8. A second return spring 21 is fixedly connected between one side of the movable block 19 and the inner wall of the inclined sliding seat 20. Collection boxes 22 are arranged on both sides of the stamping table 2.

[0041] During operation: When the scraping blade plate 6 horizontally moves away from the surface of the steel plate, the scraps will fall into the interiors of the two collection boxes 22. And when the scraping blade plate 6 continues to move, the top of its inclined surface will come into contact with the tip of the anti-scraping plate 18. And under the restriction of the anti-scraping plate 18, the scraping blade plate 6 will slide along the inner wall of the inclined sliding seat 20 through the movable block 19, causing the scraping blade plate 6 to move obliquely upward. The inclined surface of the scraping blade plate 6 rubs against the surface of the anti-scraping plate 18 during the sliding process, and under the action of mechanical scraping, the residual scraps are removed. The scraps cleaned by the anti-scraping plate 18 will also slide down along its inclined surface into the collection box 22. When the scraping blade plate 6 horizontally moves back to its original position in the reverse direction, the second return spring 21 releases its elastic potential energy, pushing the movable block 19 to slide down along the inclined sliding seat 20, and the scraping blade plate 6 returns to its initial position.

[0042] As Figures 8 to 9 shown, the material pushing assembly includes a trapezoidal platform 29. The top of the inclined surface of the trapezoidal platform 29 is slidably connected to a movable plate 34. A plurality of push rods 35 are fixedly connected to one side of the movable plate 34, and the plurality of push rods 35 are arranged in an arc. A magnetic attraction assembly is arranged above the trapezoidal platform 29, and the magnetic attraction assembly is used to drive the trapezoidal platform 29 to rise.

[0043] During operation: When the stamping die 5 moves downward and completes the stamping work, when the stamping die 5 rises and resets, it will drive the trapezoidal platform 29 to rise synchronously. When the trapezoidal platform 29 moves upward, it will cause the movable plate 34 to slide along the inclined surface of the trapezoidal platform 29. Under the action of the inclined surface thrust, the movable plate 34 will move horizontally, causing multiple push rods 35 to push forward. The multiple push rods 35 are arranged in an arc, which is adapted to the outer edge of the stamped arc-shaped fender. When the push rods 35 push forward, they will push the stamped fender away from above the stamping table 2, thereby pushing out and discharging the formed arc-shaped fender from the side of the stamping table 2, achieving the effect of rapid blanking.

[0044] As Figures 8 to 9 shown, the magnetic attraction component includes a connecting frame 27. The connecting frame 27 is fixedly connected to the side wall of the lifting plate 4. An electromagnet 28 is fixedly connected to the bottom end of the connecting frame 27. An iron block 30 is fixedly connected to the top of the trapezoidal platform 29.

[0045] During operation: When the stamping die 5 descends for stamping, it will drive the electromagnet 28 to descend synchronously through the connecting frame 27. After stamping is completed, the electromagnet 28 contacts the iron block 30. At this time, when an electric current is passed through the electromagnet 28, the electromagnet 28 can adsorb the iron block 30 after passing through the current, so that it can drive the trapezoidal platform 29 to move upward synchronously when rising, thereby causing the movable plate 34 to slide along the inclined surface of the trapezoidal platform 29, resulting in multiple push rods 35 pushing forward to push the fender out from the side of the stamping table 2.

[0046] As Figures 8 to 9 shown, inner slider threes 31 are fixedly connected to both sides of the trapezoidal platform 29. Vertical sliding seats 32 are symmetrically and fixedly connected to the top of the processing table 1. The inner slider threes 31 are respectively slidably connected to the inner walls of the vertical sliding seats 32 and are mutually adapted. Counterweight blocks 33 are fixedly connected below the connecting rods between the two inner slider threes 31 and the trapezoidal platform 29.

[0047] During operation: When the trapezoidal platform 29 rises, the inner slider threes 31 will slide upward along the inner walls of the vertical sliding seats 32 to improve the stability of the upward movement of the trapezoidal platform 29. And when the trapezoidal platform 29 rises to a certain height, after the push rods 35 completely push the fender out from the side of the stamping table 2, at this time, the electromagnet 28 disconnects the current, and the trapezoidal platform 29 will naturally fall and reset under its own gravity and the action of the counterweight block 33. When the trapezoidal platform 29 falls, the movable plate 34 slides reversely along the inclined surface, and the push rods 35 retract to the initial position.

[0048] As Figure 1 and Figure 3As shown in the figure, a water supply tank 23 and a water storage tank 25 are symmetrically and fixedly connected to the top of the lifting plate 4. A water supply pipe 24 and a return suction pipe 26 are fixedly connected to one side of the water supply tank 23 and the water storage tank 25 respectively. The other ends of the water supply pipe 24 and the return suction pipe 26 are fixedly connected to the inner wall of the stamping die 5. The middle parts of the water supply pipe 24 and the return suction pipe 26 are made of bellows material, and a coolant is provided inside the water supply pipe 24.

[0049] During operation: The water supply tank 23 supplies the coolant to the stamping die 5 through the water supply pipe 24. Since the stamping die 5 always fits against the top of the steel plate during stamping, the formed fender is cooled, and the coolant after absorbing heat is recycled to the water storage tank 25 through the return suction pipe 26. The middle parts of the return suction pipe 26 and the water supply pipe 24 are made of bellows material, so as to facilitate the return suction pipe 26 and the water supply pipe 24 to adapt to expansion and contraction.

[0050] As Figure 2 and Figure 8 shown in the figure, a blanking table 36 is lapped on one side of the stamping table 2, and the blanking table 36 is fixedly installed on the top of the processing table 1.

[0051] During operation: By means of the provided blanking table 36, when the formed fender is pushed out from the side of the stamping table 2 through the push rod 35, it will fall onto the inclined surface of the blanking table 36, and the arc-shaped fender can enter the next processing equipment along the inclined surface of the blanking table 36 for other process processing of the fender.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
