Description

Technical Field

[0001] This utility model relates to the field of reinforcing rib technology, and more specifically, to a stamping die for producing vehicle reinforcing ribs. Background Technology

[0002] In vehicle manufacturing, reinforcing ribs play a crucial role in enhancing the strength and rigidity of the vehicle body structure. Stamping dies are one of the core pieces of equipment for producing vehicle reinforcing ribs. Through the stamping action of the dies, metal sheets can be quickly and efficiently processed into reinforcing rib components with specific shapes and sizes.

[0003] Chinese Patent Announcement No. 202222718146.2 discloses a clamping device for reinforcing rib stamping dies. This solution involves placing the workpiece on a mounting platform on a support when stamping it with a reinforcing rib die. Then, cylinder one is activated, causing the hinge seat to move downwards horizontally. Next, the first support rod on the hinge seat rotates the second support rod, thereby fixing the workpiece with clamping rods at both ends. Then, cylinder two is activated, causing the pressure plate to stamp the workpiece (the pressure plate slides through a sliding sleeve on the support frame, which also has a limit ring to reduce the downward pressure of the device). Through this simple design, the clamping device provides good clamping and fixing of the workpiece, preventing it from easily deviating during stamping.

[0004] However, after the above-mentioned patent was improved, the feeding and stamping actions could not be carried out continuously, which interrupted the rhythm of the entire production process and further reduced the overall production efficiency. Therefore, in order to solve the above problems, a stamping die for the production of vehicle reinforcing ribs is proposed. Utility Model Content

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution places the vehicle reinforcing ribs on the top of the lower cylinder and uses a third servo motor, conveyor belt and synchronous wheel to achieve synchronous rotation of several lower cylinders outside the conveyor roller, thereby accurately and continuously conveying the vehicle reinforcing ribs to the working area of ​​the stamping structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A stamping die for producing vehicle reinforcing ribs includes a housing 1, a base 2 on one side of the housing 1, a stamping structure 3 on the base 2, several conveying rollers 4 between the inner walls of the two sides of the housing 1, a lower cylinder 5 fixedly installed on the outer side of each of the conveying rollers 4, several upper cylinders 6 and two upper auxiliary blocks 7 between the inner walls of the two sides of the housing 1, a fixing rod 8 fixedly installed on each of the two adjacent upper cylinders 6 and the side of the upper cylinder 6 closest to the housing 1, and the fixing rod 8 fixedly connected to the housing 1, a lower auxiliary block 9 rotatably connected to the bottom of each of the two upper auxiliary blocks 7, a first electric telescopic rod 10 fixedly installed inside each of the several upper cylinders 6 and the two lower auxiliary blocks 9, a frame 11 fixedly installed at the output end of the first electric telescopic rod 10, the frame 11 passing through the bottom of the upper cylinders 6 and the lower auxiliary blocks 9 and slidably connected to them, an auxiliary roller rotatably connected to the outer side of each of the several frame 11, and a clamping structure and a limiting structure provided on the base 2.

[0028] By using the existing transmission structure, the vehicle reinforcing ribs are placed on the top of the lower cylinder 5. Through the cooperation of the third servo motor, conveyor belt and synchronous wheel, the synchronous rotation of several lower cylinders 5 outside the conveyor roller 4 is achieved, thereby accurately and continuously conveying the vehicle reinforcing ribs to the working area of ​​the stamping structure 3. The stamping structure 3 then performs stamping and forming operations on the vehicle reinforcing ribs according to the preset program. The coordinating controller 21 acts on the clamping structure and limiting structure on the device to ensure the precise coordination of feeding and stamping actions, thereby achieving an efficient and stable production process.

[0029] The two upper auxiliary blocks 7 are fixedly connected to each other and to the side of the upper auxiliary block 7 near the housing 1 by a fixing rod 8. The two upper auxiliary blocks 7 are fixedly installed with a second electric telescopic rod 13. The output end of the second electric telescopic rod 13 is fixedly installed with a rack, and the rack is slidably connected to the upper auxiliary block 7. The top of the lower auxiliary block 9 is fixedly installed with a first gear 12. The first gear 12 is inserted into the interior of the upper auxiliary block 7 and rotates with it. The first gear 12 meshes with the rack.

[0030] The first electric telescopic rod 10 is operated to move the auxiliary roller on the outside of the frame 11 downward, which facilitates adjustment according to the size of the reinforcing rib. The vehicle reinforcing rib is conveyed through the lower cylinder 5, and the auxiliary roller also presses the vehicle reinforcing rib. The outer surfaces of several lower cylinders 5 and auxiliary rollers are wrapped with rubber or polyurethane material to increase the friction between them and the vehicle reinforcing rib and prevent the sheet metal from slipping during feeding. The stamping structure 3 is an existing structure, and the upper and lower dies on the stamping structure 3 are fixed with existing fixing bolts.

[0031] At the same time, the operation of the second electric telescopic rod 13 causes the rack to drive the first gear 12 to rotate, adjusting the angle of the auxiliary rollers on the lower auxiliary block 9 and the frame 11, so as to guide the vehicle reinforcing ribs to be accurately transported through the lower cylinder 5.

[0032] Several conveyor rollers 4 are inserted into the interior of the housing 1 and rotatably connected thereto. The interior of the housing 1 is provided with a transmission structure that cooperates with the conveyor rollers 4. The transmission structure includes a third servo motor, a conveyor belt and a synchronous wheel. The stamping structure 3 consists of two cylinders, an upper module, a lower module, a limit rod and a buffer spring.

[0033] A controller 21 is embedded on one side of the housing 1. The controller 21 is electrically connected to the first electric telescopic rod 10, the second electric telescopic rod 13, the first servo motor 14, the second servo motor 18, the third electric telescopic rod 19, the infrared sensor, the cylinder and the third servo motor.

[0034] Please see Figure 5 The clamping structure includes two second gears. Two bidirectional lead screws 17 are fixedly installed on the corresponding sides of one of the second gears. Both bidirectional lead screws 17 and the second gear are rotatably connected to the base 2. Two clamping plates 16 are threaded to the outer sides of the two bidirectional lead screws 17. Several clamping plates 16 pass through the top of the base 2 and are slidably connected to it. A second servo motor 18 is fixedly installed inside the base 2. The output end of the second servo motor 18 is fixedly connected to one of the second gears.

[0035] The limiting structure includes a first servo motor 14, which is fixedly installed inside the base 2. A threaded rod is fixedly installed at the output end of the first servo motor 14. A slide plate 15 is provided inside the base 2. The slide plate 15 passes through one side of the base 2 and is slidably connected to it. The threaded rod is inserted into the interior of the slide plate 15 and is threadedly connected to it. Two third electric telescopic rods 19 are provided inside the slide plate 15. Both third electric telescopic rods 19 pass through the slide plate 15 and are fixedly connected to it. A mounting plate 20 is provided above the slide plate 15. The output ends of both third electric telescopic rods 19 are fixedly connected to the mounting plate 20. Two infrared sensors are embedded on the side of the mounting plate 20 near the housing 1.

[0036] By setting a limiting structure, the position of the conveyed vehicle reinforcing rib is sensed by an infrared sensor. When the rib is conveyed to the appropriate position, it is clamped by a clamping structure and stamped by a stamping structure 3. After the stamping operation is completed, the mounting plate 20 is moved longitudinally by the third electric telescopic rod 19. The processed vehicle reinforcing rib is pushed by the subsequently conveyed vehicle reinforcing rib, or the vehicle reinforcing rib can be picked up manually by the operator. At the same time, the threaded rod is driven by the first servo motor 14 to rotate and the slide plate 15 is moved laterally to adjust the distance between the slide plate 15 and the base 2, thereby adjusting the position of the infrared sensor. This allows for adjustment according to the stamping position of the vehicle reinforcing rib, eliminating the need for frequent repositioning during the stamping process.

[0037] Simultaneously, through the clamping structure, after the infrared sensor senses the position of the vehicle's reinforcing rib, the second servo motor 18 drives the two second gears to rotate, thereby achieving synchronous and unidirectional rotation of the two bidirectional lead screws 17. This adjusts the distance between the two clamping plates 16 located on the same bidirectional lead screw 17, thus clamping and fixing the vehicle's reinforcing rib. At the same time, the synchronous movement of the two bidirectional lead screws 17 towards each other has a corrective effect on the position of the reinforcing rib.

[0038] Working principle: By placing the vehicle reinforcing ribs on the top of the lower cylinder 5, and through the cooperation of the third servo motor, conveyor belt and synchronous pulley, the synchronous rotation of several lower cylinders 5 outside the conveyor roller 4 is achieved, thereby accurately and continuously conveying the vehicle reinforcing ribs to the working area of ​​the stamping structure 3. The position of the conveyed vehicle reinforcing ribs is sensed by an infrared sensor, and the second servo motor 18 drives two second gears to rotate, thereby achieving synchronous and unidirectional rotation of two bidirectional lead screws 17. The distance between the two clamping plates 16 located on the same bidirectional lead screw 17 is adjusted to clamp and fix the two conveyed vehicle reinforcing ribs. The two upper modules are moved down synchronously by the action of two cylinders to complete the stamping operation of the vehicle reinforcing ribs.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
