On the one hand, environmental protection will become an important direction for the development of precision forging blanks, adopting green and environmentally friendly production processes to reduce energy consumption and environmental pollution. On the other hand, the research and development of high-performance precision forging blanks will become an important direction for the industry. Through the research and development of new materials and new processes, the mechanical properties, processing properties and other comprehensive properties of precision forging blanks will be improved to meet the growing demand of high-end markets. Precision forging blanks are widely used in the automotive, machinery, aerospace and other fields.

Before the sorting mechanism 9 screens the fine forging billets, the weight intervals of the fine forging billets are pre-sorted by the visual inspection system 10. First, the material entering the receiving trough 284 is photographed by the camera 101, and the camera 101 captures a static image of the fine forging billet, obtains image information of the fine forging billet in the receiving trough 284, and transmits the static image of the fine forging billet to Preprocessing is performed in the computer 5 to obtain a contour line diagram of the precision forging billet, and the volume is estimated based on the area and length of the precision forging billet. Then, the computer 5 calculates the approximate weight of the precision forging billet based on the density and estimated volume of the precision forging billet, thereby completing the preselection of the weight range of the precision forging billet. The fill light 102 provides a light source to reduce the reflection and shadow caused by natural light that affect the calculated weight error. The compiled visual recognition software automatically analyzes the weight range corresponding to the image, and then the central control system 4 controls the receiving box 931 of the corresponding weight range to rotate to the bottom of the guide plate 29 and receive the material. At the same time, the weight range in the collection box 61 of the corresponding range rotates and faces the bottom of the corresponding receiving box 931.

[0025] Among them, the feeding component 28 includes a second stepper motor 281, the second stepper motor 281 is fixedly connected to the front of the feeding box 21, and the output end of the second stepper motor 281 is fixedly connected to the rotating rod 282.

The surface of the rotating rod 282 is fixedly connected to the feeding roller 283, and the feeding roller 283 is located inside the feeding box 21.
[0026] Among them, a material receiving trough 284 is provided on the surface of the feeding roller 283, and a rubber pad 285 is fixedly connected to the inside of the material receiving trough 284. The material receiving trough 284 allows the precision forging billet to be gradually transported to the top of the material receiving trough 284. The buffer pad 27 and the rubber pad 285 can play a buffering role on the fallen precision forging billet, reduce the impact and wear on the surface of the precision forging billet, and improve the sorting quality of the precision forging billet.
[0027] When feeding through the feeding mechanism 2, the hydraulic cylinder 24 drives the feeding box 21 to move up and down, so that the material can be placed into the feeding box 21 and sent up. At the same time, the slider 22 slides inside the slide rail 23 to ensure the stability of the feeding box 21 during the up and down movement. Then the guide plate 26 sends the fine forging billet to the top of the feeding assembly 28, and then falls into the inside of the receiving trough 284.

The fine forging billets inside the feeding box 21 enter the inside of the receiving trough 284 one by one and as the feeding roller 283 rotates, the fine forging billets enter the inside of the receiving box through the guide plate 29.

The top of the workbench 3 is fixedly connected to a third stepper motor 64, and the output end of the third stepper motor 64 is fixedly connected to a driving gear 65. The driving gear 65 is engaged with the tooth groove 63 and is linked to the driving gear 65. The driving gear 65 is driven to rotate by the third stepper motor 64. The driving gear 65 causes the collection box 61 to rotate through the tooth groove 63. The signal transceiver 7 on the collection box 61 can receive the weight signal of the pressure sensor 932, thereby performing rotation collection.
[0029] Among them, an adjustment groove 66 is opened on the inner wall of the collection box 61, and pulleys 67 are fixedly installed on both sides of the baffle 62. The pulley 67 is rollingly connected to the inside of the adjustment groove 66. The interval with a relatively large amount of fine forging billet will cause the material to squeeze the baffle 62 and cause the baffle 62 to slide in the adjustment groove 66 using the pulley 67 to change its position, thereby enabling the interval with large capacity demand to squeeze into the space with small interval, and enabling the space in the collection box 61 to change adaptively, thereby meeting the capacity requirements of different weight intervals.
[0030] Among them, an annular groove 68 is opened on the top of the workbench 3, and a ball member 69 is fixedly installed on the bottom of the collection box 61. The ball member 69 is rollingly connected to the inside of the annular groove 68. When the collection box 61 is rotated by the third stepper motor 64, the ball member 69 rolls inside the annular groove 68 at the same time, thereby reducing the friction between the collection box 61 and the workbench 3, extending the service life of the equipment, reducing the noise generated by the friction of the equipment, and improving the quality of the surrounding working environment.
[0031] Among them, the sorting mechanism 9 includes a rotating frame 91, which is located inside the through hole 8. The top of the base 1 is fixedly connected to a first stepper motor 92, and the output end of the first stepper motor 92 is fixedly connected to the bottom of the rotating frame 91. A weighing component 93 is provided on the top of the rotating frame 91, and the number of weighing components 93 is set to multiple.
[0032] Among them, the weighing assembly 93 includes a receiving box 931, the bottom of the receiving box 931 is fixedly connected to a pressure sensor 932, the bottom of the pressure sensor 932 is fixedly connected to a rotating plate 933, one side of the bottom of the rotating plate 933 is rotatably connected to a fixed rod 934, the other side of the bottom of the rotating plate 933 is rotatably connected to an electric telescopic rod 935, the bottom end of the fixed rod 934 and the bottom end of the electric telescopic rod 935 are commonly fixedly connected with a mounting seat 936, the bottom of the mounting seat 936 is fixedly connected to the top of the rotating frame 91, the side of the receiving box 931 away from the rotating frame 91 is rotatably connected to a door panel 937, and one side of the door panel 937 is commonly fixedly connected to the inner wall of the receiving box 931 with an arc-shaped elastic The telescopic rod 938 and the rotation of the second stepper motor 281 can continuously take away the precision forging billet and transmit it to the inside of the receiving box 931 through the guide plate 26. At this time, the pressure sensor 932 measures the weight of the precision forging billet, and the weight signal detected by the pressure sensor 932 is transmitted to the signal receiver. When the signal receiver receives the signal matching the signal emitted by the signal transmitter, the electric telescopic rod 935 works and moves upward. Due to the action of the fixed rod 934, one side of the rotating plate 933 rotates, thereby driving one side of the receiving box 931 to tilt. The precision forging billet pushes open the door panel 937 under the action of its own gravity and enters the collection box 61 of the corresponding weight range.
[0033] During operation: when sorting fine forging billets of different weight ranges, the fine forging billets are first transported to one side of the sorting mechanism 9 by the feeding mechanism 2. Before the sorting mechanism 9 screens the fine forging billets, the weight range of the fine forging billets is pre-sorted by the visual inspection system 10. First, the material entering the receiving trough 284 is photographed by the camera 101. The camera 101 captures a static image of the fine forging billet, obtains the image information of the fine forging billet in the receiving trough 284, and transmits the static image of the fine forging billet to the computer 5 for preprocessing to obtain the contour line diagram of the fine forging billet. The volume is estimated according to the area and length of the fine forging billet, and then the computer 5 calculates the approximate weight of the fine forging billet according to the density and estimated volume of the fine forging billet, thereby completing the sorting of the fine forging billet. The weight interval is pre-selected, and the fill light 102 provides a light source to reduce the reflection and shadow caused by natural light that affect the calculated weight error. The weight interval corresponding to the image is automatically analyzed by the compiled visual recognition software. Then, the central control system 4 controls the receiving box 931 of the corresponding weight interval to rotate to the bottom of the guide plate 29 and receive the material. At the same time, the weight interval in the collection box 61 of the corresponding interval rotates and faces the bottom of the corresponding receiving box 931. Then, the weighing component 93 is used to weigh and confirm that the weight of the fine forging billet belongs to this interval, and the sorting is completed. Among them, the fill light 102 can provide stable lighting and improve image clarity. The fine forging billets of different weight intervals can be distinguished and collected through the collection mechanism 6, and the space can be adaptively adjusted according to the storage capacity of different intervals. When putting the fine forging billet into the feeding box 21, firstly, the central control system 4 controls the hydraulic rod 25 in the hydraulic cylinder 24 to move downward, and the hydraulic rod 25 drives the feeding box 21 to move downward, while the slider 22 slides inside the slide rail 23 until the height of the feeding box 21 is convenient for people to put the fine forging billet into the feeding box 21, and put the fine forging billet that needs to be sorted into the feeding box 21. Similarly, the hydraulic rod 25 drives the feeding box 21 to move upward until one end of the guide plate 29 is connected with the top of the weighing assembly 93, and the fine forging billet in the feeding box 21 is connected. The guide plate 26 guides the forged billet to the bottom side of the feed box 21, and the buffer pad 27 can play a certain buffering role on the guide plate 26 when the forged billet falls onto the guide plate 26, thereby extending the service life of the guide plate 26. The central control system 4 starts the second stepper motor 281 to work, and the second stepper motor 281 drives the feed roller 283 to rotate intermittently through the rotating rod 282. The forged billets in the feed box 21 enter the inside of the receiving trough 284 one by one and, as the feed roller 283 rotates, the forged billets enter the inside of the weighing assembly 93 through the guide plate 29. When the fine forging blank is screened by the sorting mechanism 9, the fine forging blank guided by the feeding assembly 28 is transferred to the interior of the receiving box 931. The rotation of the second stepper motor 281 can continuously take the fine forging blank and transmit it to the interior of the receiving box 931 through the guide plate 26. At this time, the pressure sensor 932 measures the weight of the fine forging blank. The weight signal detected by the pressure sensor 932 is transmitted to the signal receiver. When the signal receiver receives the signal transmitted by the signal transmitter that matches it, the electric telescopic rod 935 works and the electric telescopic rod 935 moves upward. The fixed rod 934 causes one side of the rotating plate 933 to rotate, thereby driving one side of the receiving box 931 to tilt. The fine forging blank pushes open the door panel 937 under the action of its own gravity and enters the collection box 61 of the corresponding weight range. Then the electric telescopic rod 935 returns to its original position, and the door panel 937 is straightened under the action of the arc-shaped elastic telescopic rod 938. The first stepper motor 92 drives the rotating frame 91 to rotate. The rotation of the rotating frame 91 drives the empty receiving box 931 to rotate. The empty receiving box 931 rotates to the origin to continue receiving materials and weighing and sorting. The weighed fine forging blanks are classified and collected by the collecting mechanism 6, and the weight information is transmitted by the pressure sensor 932. The signal transceiver 7 on the collecting box 61 receives the weight information of the fine forging blanks, and then the fine forging blanks in the receiving box are thrown into the corresponding weight interval. If the weight of the blanks in the receiving box does not match the weight interval of the collecting box 61 below, the receiving box and the corresponding weight interval are rotated and approached at the same time until the blanks in the receiving box can be put into the interval. When the receiving box and the corresponding weight interval are approached at the same time, the third stepper motor 64 rotates in the tooth groove 63 through the driving gear 65, thereby driving the collecting box 61 to rotate, and then the collecting box 61 of the corresponding weight interval can be rotated, and the ball bearing 69 rolls in the annular groove 68, reducing the friction between the collecting box 61 and the workbench 3, extending the service life of the equipment and reducing the noise caused by friction. At the same time, the first stepper motor 92 drives the receiving box to rotate, thereby the pressure sensor 93 2 and the signal transceiver 7 of the corresponding weight interval are close to each other until the signal transceiver 7 receives the signal matching with it sent by the pressure sensor 932, and then the fine forging billet is put in. Since the amount of fine forging billets collected during sorting of fine forging billets in different weight intervals is different, the corresponding required collection capacity is different. Some weight intervals have a large amount of fine forging billets, while some weight intervals have a small amount or no fine forging billets, so that different weight intervals in the collection box 61 may have insufficient collection capacity or waste of space. By utilizing the settings of the baffle 62, the pulley 67 and the adjusting groove 66, the interval with a large amount of fine forging billets will cause the material to squeeze the baffle 62 and cause the baffle 62 to slide in the adjusting groove 66 by the pulley 67 to change its position, thereby enabling the interval with a large capacity requirement to squeeze into the space with a small interval, and enabling the space in the collection box 61 to change adaptively, thereby meeting the capacity requirements of different weight intervals.
