Description

Technical Field

[0001] The present invention relates to the technical field of hot forging, and particularly to an automatic flipping device for a forging production line. Background Art

[0002] Hot forging technology is a hot extrusion process, and its structural feature is the organic combination of the stamping method and the forming method of the cavity die. At present, hot forging technology has been widely applied to the forming of large-sized high-strength fasteners. Currently, the commonly used hot forging bolt forming utilizes the pressure of a punching press to enable the red-hot metal placed in the hot forging die to flow in the cavity and finally form. Through forging processing, the strength and hardness of the bolt blank can be significantly improved, and its wear resistance, corrosion resistance, high-temperature resistance, tensile resistance and other properties can be remarkably enhanced. Moreover, forging can also optimize the internal crystal structure of the bolt blank and reduce the occurrence of defective tissues, thereby improving its overall mechanical properties and durability.

[0003] There are some limitations in the existing traditional processes:

[0004] (1) The traditional process usually divides the production process into multiple independent processes. For example, devices such as conveying, heating, clamping and flipping for loading are all set separately. Thus, in actual production, the bolt blanks need to be frequently transferred among multiple devices, which not only increases the logistics cost but also reduces the integration degree of the device due to the large floor area of the devices.

[0005] (2) Limited by the process, the production environment is often harsh, the on-site operators face a relatively high labor intensity, quality control becomes difficult, the production efficiency is low. In addition, the accumulation phenomenon between processes has a serious impact on lean production.

[0006] In view of the above problems, it is particularly necessary to design an automatic flipping device for a forging production line with a high degree of integration to improve the working efficiency and reduce the labor intensity of the staff. Summary of the Invention

The second conveying mechanism 3 consists of a conveying chain two 31 and a V-shaped conveying plate 32. The clamping mechanism 6 is arranged on the upper surface of one side of the frame 1 close to the second conveying mechanism 3.

On one side wall of the frame 1 close to the conveying platform 202, a supporting plate one 7 is fixedly connected. On the upper surface of the supporting plate one 7, a pushing cylinder one 8 is installed. On one side of the upper surface of the frame 1 close to the second conveying mechanism 3, an aligning cylinder one 9 is installed. On the upper surface of the aligning cylinder one 9, a photoelectric sensor two 10 is installed. On one side of the upper surface of the frame 1 far from the aligning cylinder one 9, an aligning cylinder two 11 is installed. On the upper surface of one side of the frame 1 close to the aligning cylinder one 9, a pushing cylinder two 12 is installed. The heating mechanism 4 is installed on the upper surface of one side of the frame 1 close to the pushing cylinder two 12. The heating mechanism 4 consists of a furnace body 41, an induction coil 42 installed below the furnace body 41 and the V-shaped conveying plate 32, and a display 43 installed on the upper surface of the frame 1. On one side of the heating mechanism 4, a temperature detection sensor 13 is arranged. The temperature detection sensor 13 is electrically connected to the pushing cylinder two 12. On the upper surface of one side of the frame 1 close to the clamping mechanism 6, a V-shaped groove plate 14 is fixedly connected. On the upper surface of one side of the frame 1 close to the V-shaped groove plate 14, a pushing cylinder three 15 is fixedly connected. On the upper surface of the pushing cylinder three 15, a photoelectric sensor three 16 is installed. On one side of the frame 1, a PLC controller 17 is installed.

[0033] In this embodiment, through the settings of the first conveying mechanism 2, the second conveying mechanism 3, the heating mechanism 4, the clamping mechanism 6 and the flipping mechanism 5, it is convenient to realize the automatic conveying, transfer, heating, clamping and flipping of bolt blanks, so as to realize automatic feeding, without the need for staff to be on-site for feeding operations, thus avoiding staff working in a high-temperature environment for a long time, and further improving safety.

[0034] Specifically, one side of the conveying platform 202 is provided with an inclined surface. The photoelectric sensor one 203 is electrically connected to the pushing cylinder one 8.

[0035] In this embodiment, by setting the inclined surface, it is convenient for the bolt blanks to be conveyed to the conveying platform 202 through the conveying chain one 201.

[0036] Specifically, the size of the pushing cylinder two 12 is adapted to the size of the V-shaped conveying plate 32, and the height of the display 43 is higher than the heights of the aligning cylinder one 9 and the pushing cylinder two 12.

[0037] In this embodiment, the blanking cylinder 1-9 and the feeding cylinder 2-12 can pass through the display 43 for pushing and use.

[0038] Specifically, a first pressure sensor 18 is fixedly connected to the upper surface of one side of the frame 1 close to the second conveyor chain 31. The first pressure sensor 18 is electrically connected to the blanking cylinder 1-9. A second pressure sensor 19 is fixedly connected to one side of the blanking cylinder 2-11. The second pressure sensor 19 is electrically connected to the blanking cylinder 2-11. A third pressure sensor 20 is fixedly connected to one side of the frame 1 close to the blanking cylinder 2-11. The third pressure sensor 20 is electrically connected to the feeding cylinder 2-12.

[0039] In this embodiment, the first pressure sensor 18, the second pressure sensor 19 and the third pressure sensor 20 are installed. When the blanking cylinder 1-9 abuts against the first pressure sensor 18, the first pressure sensor 18 can transmit an electrical signal to the PLC controller 17, and the PLC controller 17 drives the blanking cylinder 1-9 to close. When the second pressure sensor 19 abuts against one end of the bolt blank, the second pressure sensor 19 transmits an electrical signal to the PLC controller 17, and the PLC controller 17 closes the blanking cylinder 2-11. Thus, the bolt blank is limited at a position close to the induction coil 42 on the V-shaped transfer plate 32 by the blanking cylinder 1-9 and the blanking cylinder 2-11 for heating and transfer. When the feeding cylinder 2-12 pushes the bolt blank so that one end of the bolt blank abuts against the third pressure sensor 20, the third pressure sensor 20 transmits an electrical signal to the PLC controller 17, and the PLC controller 17 controls the feeding cylinder 2-12 to return to its original position.

[0040] Specifically, the clamping mechanism 6 includes a clamping groove 61 movably connected to one side of the upper surface of the frame 1. Both side walls of the clamping groove 61 are fixedly connected with second support plates 62. A clamping cylinder 63 is installed on the upper surface of the second support plates 62. A clamping plate 64 is fixedly connected to one side of the clamping cylinder 63. A fourth photoelectric sensor 65 is installed on the upper surface of one side of the clamping groove 61. The clamping cylinder 63 is electrically connected to the fourth photoelectric sensor 65.

[0041] In this embodiment, when the heated bolt blank is pushed from the inner wall of the V-shaped groove plate 14 to the inner wall of the clamping groove 61 by the feeding cylinder 3-15 and is detected by the fourth photoelectric sensor 65, the fourth photoelectric sensor 65 is electrically connected to the PLC controller 17. Thus, the fourth photoelectric sensor 65 transmits an electrical signal to the PLC controller 17, and the PLC controller 17 drives the clamping cylinders 63 on both sides to start.

[0042] Specifically, the flipping mechanism 5 includes a third support plate 51 fixedly connected to one side wall of the frame 1. A first servo motor 52 is fixedly connected to one side of the third support plate 51. The output end of the first servo motor 52 is fixedly connected to a first rotating shaft 53. The first rotating shaft 53 is fixedly connected to the clamping groove 61. The first servo motor 52 is electrically connected to the fourth photoelectric sensor 65.

[0043] In this embodiment, the first servo motor 52 is electrically connected to the PLC controller 17 (Programmable Logic Controller) and is powered by an external power supply. The first servo motor 52 is driven to start by the PLC controller 17. When the first servo motor 52 starts, it drives the clamping groove 61 to rotate through the first rotating shaft 53, thereby flipping the clamping mechanism 6 to facilitate the transfer of the heated bolt blank to the next forging machine for forging.

[0044] Specifically, a groove 21 is formed on the upper surface of one side of the frame 1. A second servo motor 22 is fixedly connected to the side wall of the frame 1 close to the groove 21. The output end of the second servo motor 22 is fixedly connected to a second rotating shaft 23. A first driving sprocket 24 is fixedly connected to the outer surface of the second rotating shaft 23. The first driving sprocket 24 is meshed with a first transmission chain 201. The inner wall of the other side of the first transmission chain 201 is meshed with a first driven sprocket 25, and the first driven sprocket 25 is rotatably connected to the frame 1.

[0045] In this embodiment, the second servo motor 22 is electrically connected to the PLC controller 17 (Programmable Logic Controller) and is powered by an external power supply. The second servo motor 22 is driven to start by the PLC controller 17 (Programmable Logic Controller). When the second servo motor 22 starts, it drives the first driving sprocket 24 to rotate through the second rotating shaft 23. The first driving sprocket 24 rotates and meshes with the first transmission chain 201 to drive the first transmission chain 201 to rotate. The rotation of the first transmission chain 201 drives the first driven sprocket 25 to rotate. Placing the bolt blank on the first transmission chain 201 enables transmission and processing, which is convenient to use.

[0046] Specifically, the number of the second transmission chains 31 is two. The two second transmission chains 31 are respectively arranged at both ends of the V-shaped transmission plate 32. The number of the V-shaped transmission plates 32 is several. The several V-shaped transmission plates 32 are fixedly connected between the two second transmission chains 31 in an annular array. The inner walls of the second transmission chains 31 are symmetrically meshed with a second driving sprocket 26 and a second driven sprocket 27.

[0047] In this embodiment, the second transmission chain 31 can drive the V-shaped transmission plate 32 to drive, thereby realizing the transmission operation of the bolt blank. The second transmission chain 31 rotates through the second driving sprocket 26 and the second driven sprocket 27.

[0048] Specifically, a side wall of the frame 1 close to the second driving sprocket 26 is fixedly connected with a third servo motor 28. The output end of the third servo motor 28 is fixedly connected with a third rotating shaft 29. The third rotating shaft 29 penetrates through the second driving sprocket 26 and is fixedly connected with the second driving sprocket 26. The third rotating shaft 29 penetrates through the frame 1 and is rotatably connected with the frame 1. The second driven sprocket 27 is rotatably connected with the frame 1.

[0049] In this embodiment, the third servo motor 28 is electrically connected to the PLC controller 17 (Programmable Logic Controller) and is powered by an external power supply. The third servo motor 28 is the driving body of the second conveyor chain 31. By driving the third servo motor 28 to start through the PLC controller 17, the third servo motor 28 drives the second driving sprocket 26 to rotate through the third rotating shaft 29. The rotation of the second driving sprocket 26 meshes with the second conveyor chain 31 to drive the second conveyor chain 31 to rotate. The rotation of the second conveyor chain 31 drives the second driven sprocket 27 to rotate. At the same time, the rotation of the second conveyor chain 31 drives the V-shaped conveyor plate 32 on one side thereof to rotate to convey the bolt blanks, so as to facilitate the realization of the purpose of conveying the bolt blanks.

[0050] Specifically, the lower surface of the frame 1 is fixedly connected with a support base 30.

[0051] In this embodiment, installing the support base 30 facilitates improving the overall placement stability of the frame 1 and ensuring the operation of the device.

[0052] Working principle: First, the bolt blanks are conveyed to the conveying platform 202 through the first conveyor chain 201 and are detected by the first photoelectric sensor 203. The first photoelectric sensor 203 transmits an electrical signal to the PLC controller 17. The PLC controller 17 drives the first pushing cylinder 8 to start. The first pushing cylinder 8 pushes the bolt blanks onto the V-shaped conveyor plate 32 for conveying through the second conveyor chain 31. At the same time, the second photoelectric sensor 10 detects the position of the bolt blanks and drives the first aligning cylinder 9 and the second aligning cylinder 11 to start through the PLC controller 17. The first aligning cylinder 9 and the second aligning cylinder 11 move towards each other. One side of the first aligning cylinder 9 abuts against the first pressure sensor 18, so that the first aligning cylinder 9 is closed through the PLC controller 17. When the second pressure sensor 19 on one side of the second aligning cylinder 11 abuts against one end of the bolt blanks, the second aligning cylinder 11 is closed through the PLC controller 17. Thus, the bolt blanks are limited to one side close to the induction coil 42 by the first aligning cylinder 9 and the second aligning cylinder 11;

[0053] Afterwards, one end of the bolt blank is heated by the heating mechanism 4. The furnace body 41 is an intermediate frequency induction heating furnace. A magnetic field is formed by the induction coil 42, and the bolt blank is located in the magnetic field area of the induction coil 42. Thus, the bolt blank is heated by the induction coil 42. During heating, the bolt blank is conveyed by the V-shaped conveying plate 32 and the second conveying chain 31, so as to ensure the uniformity of heating at one end of the bolt blank. When the bolt blank is heated and conveyed by the V-shaped conveying plate 32 to the side close to the temperature detection sensor 13, the temperature detection sensor 13 detects the temperature of the bolt blank. When the temperature is qualified, the temperature detection sensor 13 transmits an electrical signal to the PLC controller 17. The PLC controller 17 drives the second pushing cylinder 12 to start. The second pushing cylinder 12 pushes the bolt blank with heating completed out of the area of the induction coil 42. At the same time, when one end of the bolt blank with heating completed abuts against the third pressure sensor 20, the third pressure sensor 20 drives the second pushing cylinder 12 to return to its original position through the PLC controller 17. The bolt blank with heating completed is conveyed by the V-shaped conveying plate 32 to the inner wall of the V-shaped groove plate 14;

[0054] Finally, when the bolt blank with heating completed on the inner wall of the V-shaped groove plate 14 is detected by the third photoelectric sensor 16, the third photoelectric sensor 16 drives the third pushing cylinder 15 through the PLC controller 17. The third pushing cylinder 15 pushes the bolt blank in the V-shaped groove plate 14 into the clamping mechanism 6. When the fourth photoelectric sensor 65 detects the bolt blank, it drives the clamping cylinder 63 to start through the PLC controller 17 to clamp the bolt blank in the clamping groove 61. At the same time, the fourth photoelectric sensor 65 drives the first servo motor 52 to start through the PLC controller 17. The first servo motor 52 drives the clamping groove 61 to flip through the first rotating shaft 53, so as to facilitate the feeding of the bolt blank, realizing the automatic conveying, transfer, heating, clamping and flipping feeding of the bolt blank, with a higher degree of integration. And it does not require staff to operate on site, thus avoiding the staff working in a high-temperature environment and ensuring the safety of the staff, and effectively improving the work efficiency.
