Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer toFigures 1-7 , the present invention provides a technical solution: a processing production line for a motorcycle fender side cover, including a transmission component 1 that is transmitted in a circumferential direction. Along the counterclockwise direction of the transmission component 1, a feeding component 2, a first stamping component 3, a second stamping component 4, a third stamping component 5, a punching component 6, a punching and cutting component 7, and a discharging component 8 are arranged in sequence.

[0020] The transmission component 1 includes a rotatable turntable 9. A fixed column 10 is rotatably connected to the lower side of the center of the turntable 9 through a bearing. A cavity 11 is opened in the fixed column 10. A driving motor 12 is fixedly connected in the cavity 11. The output shaft of the driving motor 12 is fixedly connected to the center of the turntable 9, so as to drive the turntable 9 to rotate through the driving motor 12; The feeding component 2, the first stamping component 3, the second stamping component 4, the third stamping component 5, the punching component 6, the punching and cutting component 7, and the discharging component 8 are evenly distributed in a circle with the center of the turntable 9 as the reference.

[0021] As Figure 2 , seven material placement openings 13 are opened on the turntable 9. The seven material placement openings 13 are evenly distributed in a circle with the center of the turntable 9 as the center of the circle. The seven material placement openings 13 respectively correspond to the feeding component 2, the first stamping component 3, the second stamping component 4, the third stamping component 5, the punching component 6, the punching and cutting component 7, and the discharging component 8.

[0022] The driving motor 12 drives the turntable 9 to rotate, so that each time it rotates, the seven material placement openings 13 are all located directly above the feeding component 2, the first stamping component 3, the second stamping component 4, the third stamping component 5, the punching component 6, the punching and cutting component 7, and the discharging component 8.

[0023] A groove 14 is commonly opened on the inner walls of the four sides of each material placement opening 13. The groove 14 is a rectangular frame structure groove, and the groove 14 communicates with the material placement opening 13.

[0024] Two support plates 15 that are oppositely arranged in the radial direction of the turntable 9 and two support plates 16 that are oppositely arranged in the circumferential tangential direction of the turntable 9 are slidably arranged in the groove 14. The cross-sectional shapes of the support plates 15 and 16 in the vertical direction are trapezoids.

[0025] After the support plates 15 and 16 move towards the center side of the material placement opening 13, they can be combined and spliced into a support frame. The support frame has a rectangular frame structure. A sealing strip is embedded at the connection of the support plates 15 and 16 to seal the connection of the support plates 15 and 16.

[0026] On one side of the first support plate 15 away from the center of the material placing opening 13, there are two first hydraulic telescopic cylinders 17. The two first hydraulic telescopic cylinders 17 are respectively arranged on both sides of the first support plate 15 along the length direction. The fixed ends of the two first hydraulic telescopic cylinders 17 are fixedly connected to the inner wall of the first groove 14, and the output ends of the two first hydraulic telescopic cylinders 17 are fixedly connected to the first support plate 15.

[0027] On one side of the second support plate 16 away from the center of the material placing opening 13, there are two second hydraulic telescopic cylinders 18. The two second hydraulic telescopic cylinders 18 are respectively arranged on both sides of the second support plate 16 along the length direction. The fixed ends of the two second hydraulic telescopic cylinders 18 are fixedly connected to the inner wall of the first groove 14, and the output ends of the two second hydraulic telescopic cylinders 18 are fixedly connected to the second support plate 16.

[0028] In the initial state, both the first support plate 15 and the second support plate 16 are located in the first groove 14. The first support plate 15 and the second support plate 16 are respectively driven by the first hydraulic telescopic cylinder 17 and the second hydraulic telescopic cylinder 18 to move towards the side close to the center of the material placing opening 13, and are combined and spliced into a support frame to support the material plate placed in the material placing opening 13 by the feeding assembly 2.

[0029] Such as Figure 3 , the upper sides of both the first support plate 15 and the second support plate 16 are concave surfaces. A number of protrusions 19 are arranged in an array on the upper sides of the first support plate 15 and the second support plate 16. The protrusions 19 are hemispherical. The number of protrusions 19 is integrally provided with the first support plate 15. The vertices of the number of protrusions 19 are all on the same horizontal plane. Air holes 20 are opened at the centers of the number of protrusions 19. The air holes 20 are in direct contact with the lower side of the material plate supported on the support frame, so as to adsorb and fix the material plate.

[0030] Furthermore, air cavities 21 for communicating with the air holes 20 are opened in both the first support plate 15 and the second support plate 16. On one side of both the first support plate 15 and the second support plate 16 away from the center of the material placing opening 13, there are air pipes. One end of the air pipe penetrates the inner wall of the air cavity 21 and is communicated with the air cavity 21; The other end of the air pipe penetrates the turntable 9 and is connected to a vacuum pump through a gas-liquid slip ring.

The concave surface facilitates the cooling water falling on the first support plate 15 and the second support plate 16 to converge towards the lowest point of the concave surface, and flows into the water holes 22 during the convergence process; Further, water collecting cavities 53 are provided in both the first support plate 15 and the second support plate 16. The cross-sectional shape of the water collecting cavity 53 in the vertical direction is grid-shaped, which can prevent the water collecting cavity 53 from communicating with the air holes 20.

[0032] Water pipes are provided on the sides of the first support plate 15 and the second support plate 16 away from the center of the material placing port 13. One end of each water pipe penetrates the inner wall of the water collecting cavity 53 and communicates with the water collecting cavity 53; The other end of the water pipe penetrates the turntable 9 and is connected to a first liquid pump through a gas-liquid slip ring. The output end of the first liquid pump is communicated with a filter, and the output end of the filter is communicated with a liquid storage tank. Thus, the coolant in the water collecting cavity 53 is pumped into the filter by the first liquid pump, and after being filtered by the filter, it enters the liquid storage tank for recycling. The first liquid pump, the filter, and the liquid storage tank are all located below the turntable 9.

[0033] The gas-liquid slip ring is an existing conventional technology, which can transmit electricity, gas, and liquid to the mechanisms on a 360° rotating object.

The input end of the second hydraulic pump is connected to the liquid storage tank. The pipeline connecting the nozzle 25 to the second liquid pump is transferred through a gas-liquid slip ring.

[0038] The nozzle 25 faces the center of the feeding port 13 and is used to spray coolant before and after the first stamping assembly 3, the second stamping assembly 4, and the third stamping assembly 5. The coolant has both lubricating and cooling functions. Lubricate the blank before the first stamping assembly 3, the second stamping assembly 4, and the third stamping assembly 5 to reduce the friction generated during the processing of the blank by the first stamping assembly 3, the second stamping assembly 4, and the third stamping assembly 5. Cool the blank after the first stamping assembly 3, the second stamping assembly 4, and the third stamping assembly 5 to quickly cool the blank after being processed by the first stamping assembly 3, the second stamping assembly 4, and the third stamping assembly 5.

The blanking plate is intercepted by the stopper 40, and the outer shape of the blanking plate is scanned by the laser scanning sensor two 43. The processor performs three-dimensional modeling on the data scanned by the laser scanning sensor two 43; By comparing the size of the blanking plate preset in the processor with the actual size of the scanned blanking plate, it is determined whether the blanking plate meets the processing requirements; For the blanking plate that does not meet the processing requirements, the output end of the electric telescopic rod two 35 is controlled to retract, the stopper 40 rises, and the blanking plate is clamped and placed on the waste conveyor belt 52 and removed by the cooperation of the manipulator and the camera; For the blanking plate that meets the processing requirements, the upper side of the blanking plate is photographed by the upper group of cameras 44, and analyzed and detected by the processor; If it is detected that there is no problem with the upper side of the material plate, control the output end of the first electric telescopic rod 32 to extend, so that the second suction cup 34 adheres to the upper side of the material plate.

When the material plate is rotated by the turntable 9 to the discharging component 8, the manipulator of the discharging component 8 cooperates with the camera to clamp and place the material plate on the waste conveyor belt 52 for transmission and removal.

[0065] After the material plate is detected to meet the stamping requirements and have no cracks after being stamped by the third stamping assembly 5, control the output ends of the two lower hydraulic telescopic cylinders three 27 on the two connecting plates one 23 to extend. The first suction cup 26 adheres to the semi-formed mudguard side cover on the material plate. There is no punching at the attachment point of the first suction cup 26 to the mudguard side cover.
