[0001] The utility model relates to the technical field of automatic feeders, in particular to an automatic feeder for blanking and forming a sub-frame. Background Art

[0002] The automobile subframe is the skeleton of the front and rear axles and an important component of the front and rear axles. The subframe usually refers to the bracket that supports the front and rear axles and suspension, and is mainly used to connect the axles, suspension and main frame. In the production and manufacturing process of the subframe, the loading link is a crucial link. Its efficiency and flexibility directly affect the smoothness of the entire production process and product quality. In actual application, the automatic feeding machine for subframe blanking and forming usually requires the following technologies:

[0003] 1. Efficient conveying mechanism, such as conveyor belt, is used to transport the subframe;

[0004] 2. Precise positioning and control technology, such as PLC controllers used to control the start and stop of conveyor belts and their operating efficiency;

[0005] 3. Durable and lightweight shell material, adaptable to different working environments;

[0006] 4. Stable support structure to ensure the stability of the equipment during transportation;

[0007] 5. Flexible adjustment mechanism to adapt to different transportation needs.

[0008] At present, manufacturers use a variety of equipment and methods to transport the subframes that have been cut and formed.

[0009] For example, a Chinese patent discloses: an automatic feeding and processing device for automobile subframes, patent number: CN221215661U, which is provided with a feeding mechanism, a clamping block is used to fix the stable support bar, the stable support bar is used to fix the auxiliary moving cylinder, the auxiliary moving cylinder is used to make the moving slider move more stably, the moving slider is used to make the feeding plate move more stably, the feeding plate is used to fix the conveying roller to facilitate the conveying of materials, the connecting block is used to fix the supporting bottom plate, the supporting bottom plate is used to fix the adjusting hydraulic cylinder, the adjusting hydraulic cylinder is started to drive the feeding plate to move, so as to facilitate the loading.

[0010] The U-shaped guard frame is relatively fixed in the opening direction, which limits the flexibility of the loading method and makes the sub-frame only loadable from a vertical direction. It is necessary to ensure that the sub-frame can accurately drop vertically to the conveying position, which increases the difficulty of loading. Moreover, the vertical loading only increases the possibility of collision between the sub-frame and the conveying device or other equipment, which can easily cause damage to the equipment. In view of this problem, the present application proposes a solution and designs an automatic feeder with a rotatable adjustable U-shaped guard frame placement position. By rotating the U-shaped guard frame placement position, the flexibility of the device is increased when in use and the possibility of bumps and scratches is reduced. Utility Model Content

[0030] The embodiment of the present application provides an automatic feeder for blanking and forming a sub-frame, which effectively solves the problem that the above-mentioned device, by setting a U-shaped protective frame to play a limiting role in the sub-frame conveying process, makes the frame fixation more stable, and lacks a direction adjustment function. The opening direction of the U-shaped protective frame in the above-mentioned device is relatively fixed, which limits the flexibility of the loading method, so that the sub-frame can only be loaded from the vertical direction. It is necessary to ensure that the sub-frame can accurately fall vertically to the conveying position, which increases the difficulty of loading. Moreover, the fact that it can only be loaded vertically increases the possibility of collision between the sub-frame and the conveying device or other equipment, which can easily cause damage to the equipment. When loading the sub-frame, you can first adjust the hydraulic cylinder Lift the bottom plate upward to a height above the second conveyor belt, then start the cylinder, and the cylinder output shaft drives the connecting rod outward to extend, which drives the rack to slide on the bottom plate through the connecting rod. When the rack is extended, it engages and drives the gear to rotate, and the gear is engaged and rotated by the rack to drive the loading platform to rotate half a circle and slide downward to reset. At this time, the opening direction of the U-shaped protective frame is located on the side away from the main body of the device for loading, which improves the flexibility of the device. The loading direction and placement method can be changed according to the specific characteristics of the sub-frame to better adapt to these differences. Loading the sub-frame from one side can avoid unnecessary collisions between the sub-frame and the U-shaped protective frame, thereby extending the service life of the equipment and reducing equipment maintenance costs.

[0031] Example

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the problem that the above-mentioned device plays a limiting role in the transportation of the sub-frame by setting a U-shaped protective frame to make the frame more stable, and there is a problem of lack of direction adjustment function. The opening direction of the U-shaped protective frame in the above-mentioned device is relatively fixed, which limits the flexibility of the loading method, so that the sub-frame can only be loaded from the vertical direction. It is necessary to ensure that the sub-frame can accurately fall vertically to the transportation position, which increases the difficulty of loading. Moreover, only vertical loading increases the possibility of collision between the sub-frame and the transportation device or other equipment, which easily causes damage to the equipment. The overall idea is as follows: an automatic feeder for blanking and forming a sub-frame, comprising a base plate 11 and a device body 17, the base plate 11 is rotatably connected to a loading platform 12, the outer surface of the loading platform 12 is sleeved with a gear 13, the upper end of the base plate 11 is fixedly connected to a cylinder 14, the outer surface of the cylinder 14 is fixedly connected to a connecting rod 15, the inner end of the connecting rod 15 close to the cylinder 14 is fixedly connected to a rack 16, The rack 16 and the gear 13 are meshed with each other, and the end of the device body 17 close to the bottom plate 11 is fixedly connected to the adjusting mechanism. The adjusting mechanism includes a supporting base plate 18, and the supporting base plate 18 is fixedly connected to the end of the device body 17 close to the bottom plate 11. The upper end of the supporting base plate 18 is fixedly connected to four adjusting hydraulic cylinders 19, and the four adjusting hydraulic cylinders 19 are fixedly connected to the lower end of the bottom plate 11. The loading platform 12 is rotatably connected to the first conveyor belt 21, and the device body 17 is rotatably connected to the second conveyor belt 22. The first conveyor belt 21 and the second conveyor belt 22 are on the same horizontal line. The formed sub-frame that needs to be transported is placed on the first conveyor belt 21, and the first conveyor belt 21 transports the formed sub-frame to the second conveyor belt 22, and the second conveyor belt 22 transports the unloading and formed sub-frame to the next processing location. When the device is in use, the height of the base plate 11 can be adjusted by the adjusting hydraulic cylinder 19 installed on the supporting base plate 18 to make adaptive adjustments.

[0033] The upper end of the loading platform 12 is fixedly connected to a U-shaped protective frame 23. When loading the sub-frame, the bottom plate 11 can be lifted upward to a height exceeding the second conveyor belt 22 by adjusting the hydraulic cylinder 19. At this time, the cylinder 14 is started, and the output shaft of the cylinder 14 drives the connecting rod 15 to extend outward. The rack 16 is driven to slide on the bottom plate 11 through the connecting rod 15. When the rack 16 is extended, it engages and drives the gear 13 to rotate. The gear 13 is engaged and rotated by the rack 16, driving the loading platform 12 to rotate half a circle and slide downward to reset. At this time, the opening direction of the U-shaped protective frame 23 is located on the side away from the device body 17 for loading work, thereby improving the flexibility of the device. The loading direction and placement method can be changed according to the specific characteristics of the sub-frame to better adapt to these differences, and the sub-frame is loaded from one side, which can avoid unnecessary collisions between the sub-frame and the U-shaped protective frame 23 (for example, the sub-frame can smoothly enter the first conveyor belt 21 along the opening of the U-shaped protective frame 23, instead of easily colliding with the U-shaped protective frame 23 due to height differences and placement accuracy problems as in loading from the top. This can reduce the risk of scratches on the surface of the sub-frame, and at the same time protect the structural integrity of the U-shaped protective frame 23, reducing the possibility of its deformation or damage), thereby extending the service life of the equipment and reducing equipment maintenance costs.

[0034] The lower end of the loading platform 12 is fixedly connected to a rectangular plate 24, and the upper end of the bottom plate 11 is fixedly connected to two limit seats 25, and the inside of the two limit seats 25 are slidably connected to cylindrical blocks 26, and the outer surfaces of the two cylindrical blocks 26 are sleeved with rubber pads 27. Buffer springs 28 are sleeved inside the limit seats 25, and the buffer springs 28 are sleeved on the outer surfaces of the cylindrical blocks 26. When the loading platform 12 is rotated to adjust its placement position, it will drive the rectangular plate 24 to rotate. During the rotation of the rectangular plate 24, it will rotate from one end of the limit seat 25 to the other limit seat 25. At this time, the rectangular plate 24 contacts the rubber pad 27 on the surface of the cylindrical block 26, and the buffer springs 28 and the rubber pad 27 surface in the limit seat 25 play a buffering role. The limit seats 25 set at both ends can limit the rotating rectangular plate 24 to avoid excessive movement and improve the repeatability of the position, ensuring that the U-shaped protective frame 23 returns to the same set position after adjustment, which is conducive to improving the repeatability and stability of the production process.

[0035] In view of the problems existing in the prior art, the utility model provides an automatic feeder for blanking and forming the sub-frame. When loading the sub-frame, the bottom plate 11 can be lifted upward by adjusting the hydraulic cylinder 19 to a height exceeding the second conveyor belt 22. At this time, the cylinder 14 is started, and the output shaft of the cylinder 14 drives the connecting rod 15 to extend outward, and the rack 16 is driven to slide on the bottom plate 11 through the connecting rod 15. When the rack 16 is extended, it engages and drives the gear 13 to rotate. The gear 13 is engaged and rotated by the rack 16 to drive the loading platform 12 to rotate half a circle and slide downward to reset. At this time, the opening direction of the U-shaped protective frame 23 is located on the side away from the device body 17 for loading work, which improves the flexibility of the device. The loading direction and placement method can be changed according to the specific characteristics of the sub-frame to better adapt to these differences. Loading the sub-frame from one side can avoid unnecessary collision between the sub-frame and the U-shaped protective frame 23, thereby extending the service life of the equipment and reducing the equipment maintenance cost.

[0036] Working principle:

[0037] In the first step, the formed sub-frame to be transported is placed on the first conveyor belt 21. During the transportation process of the first conveyor belt 21, it can be limited by the U-shaped protective frame 23 to prevent it from deflecting. The first conveyor belt 21 transports the formed sub-frame to the second conveyor belt 22, and the second conveyor belt 22 transports the unloaded and formed sub-frame to the next processing location. When the device is in use, the height of the base plate 11 can be adjusted by the adjusting hydraulic cylinder 19 installed on the supporting base plate 18 to make adaptive adjustments.

[0038] In the second step, when loading the sub-frame, the bottom plate 11 can be lifted upward by adjusting the hydraulic cylinder 19 to a height exceeding the second conveyor belt 22. At this time, the cylinder 14 is started, and the output shaft of the cylinder 14 drives the connecting rod 15 to extend outward, and the rack 16 is driven to slide on the bottom plate 11 through the connecting rod 15. When the rack 16 is extended, it engages and drives the gear 13 to rotate. The gear 13 is engaged and rotated by the rack 16 to drive the loading platform 12 to rotate half a circle and slide downward to reset. At this time, the opening direction of the U-shaped protective frame 23 is located on the side away from the device body 17 for loading work, which improves the flexibility of the device. The loading direction and placement method can be changed according to the specific characteristics of the sub-frame to better adapt to these differences. Loading the sub-frame from one side can avoid unnecessary collision between the sub-frame and the U-shaped protective frame 23 (for example, the sub-frame can smoothly enter the first conveyor belt 21 along the opening of the U-shaped protective frame 23, instead of being easily blocked by the high load as when loading from the top). The U-shaped protective frame 23 is preferably fixed to the support frame 22 and fixed with the support frame 23 so as to avoid any scratches on the surface of the sub-frame. At the same time, it can also protect the structural integrity of the U-shaped protective frame 23 and reduce the possibility of its deformation or damage), thereby extending the service life of the equipment and reducing the maintenance cost of the equipment. When the loading platform 12 is rotated to adjust its placement position, the loading platform 12 will drive the rectangular plate 24 to rotate. During the rotation of the rectangular plate 24, it will rotate from one end of a limit seat 25 to the other limit seat 25. At this time, the rectangular plate 24 contacts the rubber pad 27 on the surface of the cylindrical block 26, and a buffering effect is played by the buffer spring 28 in the limit seat 25 and the surface of the rubber pad 27. The limit seats 25 set at both ends can limit the rotating rectangular plate 24 to avoid excessive movement and improve the repeatability of the position, ensuring that the U-shaped protective frame 23 returns to the same set position after adjustment, which is conducive to improving the repeatability and stability of the production process.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
