Technical Field

[0001] This utility model relates to the field of flange nut processing technology, specifically to a forming equipment for automotive large flange nuts. Background Technology

[0002] Large flange nuts are fasteners with a wide, flat, disc-shaped structure integrally formed below the head of a hexagonal nut. By increasing the contact area between the nut and the connected parts, they achieve a more stable connection, prevent loosening, and distribute pressure. Automotive large flange nut forming equipment is an automated, specialized device that uses plastic deformation processes such as cold heading, hot heading, or warm heading to process metal raw materials into finished automotive large flange nuts in one go or in stages. Its core function is to induce plastic flow in the material under the action of a mold, directly forming the complete structure of the nut, including the flange, hexagonal head, and internal threads.

[0003] In existing automotive large flange nut forming equipment, the blank handling process still requires manual assistance during the hot forging of flange nuts, and the work efficiency is limited by the speed of manual operation.

[0004] Therefore, a large flange nut forming machine for automobiles is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a molding equipment for automotive large flange nuts to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming equipment for automotive large flange nuts, including a forming table, wherein a material discharge groove is provided inside the forming table; A molding unit is located below the molding table and extends above the molding table. The molding unit includes a molding component and a feeding component. The molding component is used to process the blank conveyed by the feeding component, and the feeding component is used to feed the blank and the molding flange nut. The conveying unit is located outside the forming table. The conveying unit includes an adjustment component and a conveying component. The adjustment component is used to adapt to blanks of different sizes and to cause the conveying component to convey the blanks into the feeding component. With the cooperation of the forming unit and the conveying unit, the flange nut can be integrally formed. The formed flange nut can be discharged through the unloading groove opened inside the forming table.

[0007] Preferably, the molding component includes a support, a top frame is connected to the end of the support, a forging mechanism is connected inside the top frame, a push plate is connected to the end of the forging mechanism, a first bolt is sleeved inside the bottom of the push plate, and an upper mold base is sleeved on the outer wall of the first bolt.

[0008] Preferably, the feeding assembly includes a frame, a first motor is connected to the end of the frame, a rotating column is connected to the output end of the first motor, a turntable is connected to the end of the rotating column, a second bolt is sleeved inside the top surface of the turntable, and a lower mold base is sleeved on the outer wall of the second bolt.

[0009] Preferably, the upper die holder and the lower die holder are adapted to be matched, and the bottom of the lower die holder is slidably connected to the top surface of the forming table. After the upper die holder has finished hot forging the blank inside the lower die holder, the rotating turntable will transport the lower die holder to the material discharge groove inside the forming table, so that the formed flange nut can be discharged.

[0010] Preferably, the bottom of the turntable is slidably connected to the top surface of the forming table, and there are three lower mold bases distributed around the center of the turntable. The three lower mold bases are respectively used for filling blanks, forming blanks, and discharging formed blanks. With the cooperation of the three lower mold bases, the flange nut can be integrated into a single forming process.

[0011] Preferably, the adjustment assembly includes an L-shaped frame, a support plate connected to one end of the L-shaped frame, a guide block connected to the top surface of the support plate, an L-shaped plate connected to the outer wall of the support plate, and a telescopic rod connected to one end of the L-shaped plate.

[0012] Preferably, the conveying assembly includes a pusher block, a side plate connected to the bottom of the pusher block, a second motor connected to the top surface of the side plate, a drive roller connected to the output end of the second motor, a conveying chain plate sleeved on the outer wall of the drive roller, and a driven roller sleeved on the outer wall of the conveying chain plate.

[0013] Preferably, the driven roller end is rotatably connected to the inside of the side plate, and there are two conveyor chain plates symmetrically distributed around the center line of the top surface of the bearing plate. Under the constraint of the rotating conveyor chain plates, the blank can be conveyed.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This automotive large flange nut forming equipment consists of a forming unit as one component. The conveying unit feeds the heated blank into the lower die base. A first motor drives a rotating column and turntable to rotate, moving the loaded lower die base to a position aligned with the upper die base. Subsequently, the forging mechanism pushes a push plate (sliding stably along the top frame) to move the upper die base downwards, cooperating with the lower die base to complete the hot forging of the blank. After forming, the turntable continues to rotate, sending the finished product to the unloading chute for discharge. By disassembling the first and second bolts, the upper and lower die bases can be quickly replaced to accommodate the processing of flange nuts of different sizes. This structure integrates blank conveying, hot forging, and finished product discharge, improving forming efficiency. 2. This automotive large flange nut forming equipment consists of a conveying unit. First, the heated blank is placed on the support plate. A telescopic rod pushes the push block and side plate, and the distance between the two conveyor chains is adjusted according to the blank size. After starting the second motor, the driving roller drives the driven roller to rotate via the conveyor chains. The opposing rotating chains convey the blank from the support plate to the lower die holder. The blank falls into the lower die holder by its own weight, and the chains pause. Once the lower die holder moves below the upper die holder, the chains restart, continuing to feed material to other lower die holders. Guide blocks guide the blank between the chains. This structure can automatically convey heated blanks and is adaptable to conveying blanks of different sizes. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a forming equipment for automotive large flange nuts, including a forming table 1, and a material discharge groove is provided inside the forming table 1. Forming unit 2 is located below forming table 1 and extends above forming table 1. Forming unit 2 includes forming component and feeding component. Forming component is used to form the blank conveyed by feeding component. Feeding component is used to feed blank and forming flange nut. The conveying unit 3 is located outside the forming table 1. The conveying unit 3 includes an adjustment component and a conveying component. The adjustment component is used to adapt to different sizes of blanks and to cause the conveying component to convey the blanks into the feeding component.

[0024] In use, with the cooperation of forming unit 2 and conveying unit 3, the flange nut can be integrally formed and processed. The formed flange nut can be discharged through the unloading groove inside the forming table 1.

[0025] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The forming assembly includes a support 21, with a top frame 22 connected to the end of the support 21. A forging mechanism 23 is connected inside the top frame 22. A push plate 24 is connected to the end of the forging mechanism 23. A first bolt 25 is sleeved inside the bottom of the push plate 24. An upper mold base 26 is sleeved on the outer wall of the first bolt 25. The feeding assembly includes a frame 27, with a first motor 28 connected to the end of the frame 27. A rotating column 29 is connected to the output end of the first motor 28. A turntable 210 is connected to the end of the rotating column 29. A second bolt 211 is sleeved inside the top surface of the turntable 210. A lower mold base 212 is sleeved on the outer wall of the second bolt 211.

[0026] The upper die base 26 and the lower die base 212 are appropriately matched. The bottom of the lower die base 212 is slidably connected to the top surface of the forming table 1. After the upper die base 26 has finished hot forging the blank inside the lower die base 212, the rotating turntable 210 will transport the lower die base 212 to the material discharge groove inside the forming table 1, so that the formed flange nut can be discharged.

[0027] The bottom of the turntable 210 is slidably connected to the top surface of the forming table 1. There are three lower mold bases 212, which are distributed around the center of the turntable 210. The three lower mold bases 212 are used for loading blanks, forming blanks, and discharging formed blanks, respectively. With the cooperation of the three lower mold bases 212, the flange nut can be integrated into a single forming process.

[0028] During use, when forming flange nuts, the heated blank is conveyed to the lower die holder 212 via the conveying unit 3. At this time, the first motor 28 is started, which drives the rotating column 29 and the turntable 210 to rotate inside the forming table 1 and on the top surface, conveying the lower die holder 212 containing the blank directly below the upper die holder 26. When the upper die holder 26 and the lower die holder 212 are aligned, the forging mechanism 23 pushes the push plate 24 downward. Since the push plate 24 is slidably connected to the outer wall of the top frame 22, the push plate 24 moves steadily downward under the constraint of the top frame 22. The push plate 24 drives the upper die holder 26 downward as well. With the cooperation of seat 212, the blank can be hot forged into shape. After the forming is completed, the turntable 210 continues to rotate, conveying the formed flange nut to the unloading groove opened inside the forming table 1 for unloading the formed flange nut. When forming flange nuts of different sizes, the first bolt 25 can be removed to quickly replace the upper mold seat 26, and the second bolt 211 can be removed to quickly replace the lower mold seat 212, so as to form flange nuts of different sizes. This structure can integrate the conveying and hot forging of flange nut blanks, and then unload the formed flange nuts, realizing the integrated forming of flange nuts and improving the forming efficiency.

[0029] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The adjustment assembly includes an L-shaped frame 31, with a bearing plate 32 connected to the end of the L-shaped frame 31. A guide block 33 is connected to the top surface of the bearing plate 32. An L-shaped plate 34 is connected to the outer wall of the bearing plate 32. A telescopic rod 35 is connected to the end of the L-shaped plate 34. The conveying assembly includes a push block 36, with a side plate 37 connected to the bottom of the push block 36. A second motor 38 is connected to the top surface of the side plate 37. An active roller 39 is connected to the output end of the second motor 38. A conveying chain plate 310 is sleeved on the outer wall of the active roller 39. A driven roller 311 is sleeved on the outer wall of the conveying chain plate 310.

[0030] Among them, the driven roller 311 is rotatably connected to the inside of the side plate 37, and there are two conveyor chain plates 310, which are symmetrically distributed around the center line of the top surface of the bearing plate 32. Under the constraint of the rotating conveyor chain plates 310, the blank can be conveyed.

[0031] In use, when forming flange nuts, the heated blank is conveyed to the top surface of the support plate 32. At this time, the telescopic rod 35 is activated, which pushes the push block 36 and the side plate 37. The distance between the two conveyor chain plates 310 is adjusted according to the blank size. At this time, the second motor 38 is activated, which drives the drive roller 39 to rotate. The drive roller 39 drives the driven roller 311 to rotate through the conveyor chain plates 310. The two opposing conveyor chain plates 310 can convey the blank from the top surface of the support plate 32 towards the lower mold base 212. When placed above the lower die holder 212, the blank falls into the lower die holder 212 under its own weight. At this time, the conveyor chain plate 310 stops rotating. After the lower die holder 212 containing the blank is conveyed to the lower die holder 26, the conveyor chain plate 310 continues to rotate and conveys the blank to the other lower die holder 212 again. Under the restriction of the guide block 33, the blank can be guided between the conveyor chain plates 310. This structure can convey heated blanks to the lower die holder 212 and can adapt the conveying to blanks of different sizes.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
