Description

Technical Field

[0001] This utility model relates to the field of metal forging technology, and in particular to a hot upsetting device for hexagonal bolts and segment bolts. Background Technology

[0002] Hot upsetting is a process in which heated metal material is deformed under pressure in a mold to obtain the desired shape and size. In bolt production, hot upsetting is mainly used for forming the bolt head. During hot upsetting, the bolt material is deformed by a closed single-point press at high temperature, which may leave residual thermal stress, leading to a decrease in the hardness and strength of the bolt material. At the same time, thermal expansion can cause the bolt head to be too tightly bonded to the mold, increasing the difficulty of pulling it out.

[0003] In the existing processing of hexagonal bolts and segment bolts, the hexagonal head part needs to be hot-forged. However, due to the different screw lengths, the hot-forging molds for hexagonal bolts and segment bolts are usually different. Therefore, it is necessary to design two sets of molds to adapt to the hot-forging process of the hexagonal head part of hexagonal bolts and segment bolts with different screw lengths.

[0004] A search revealed that utility model patent document CN219335834U discloses a hot upsetting mold for bolt heads, including a U-shaped support block. The U-shaped support block has two cylindrical grooves inside. Each cylindrical groove has a movable shaft slidably connected to its inner wall. Each movable shaft has a support spring fixedly connected between its bottom end and the corresponding cylindrical groove inner wall. Each movable shaft has a movable support block fixedly connected to its top end.

[0005] While the aforementioned technology can push the bolts inside the forming mold to a certain extent and reduce the difficulty of removing the bolts, it still has certain shortcomings in use: the structural design is too complex, making it difficult to guarantee the ejection effect after long-term use, and it cannot adapt to the hot upsetting of hexagonal bolts and pipe bolts with different screw lengths. Therefore, it is particularly important to propose a structure that can complete the bolt ejection process with different screw lengths by adjusting the ejection device. Summary of the Invention

[0006] The purpose of this invention is to provide a hot upsetting device for hexagonal bolts and segment bolts, which can complete the pushing process of bolts with different screw lengths, reduce processing and production costs, and has a simple structure that is easy to replace and maintain.

[0007] The present invention adopts the following technical solution:

Detailed Implementation

[0033] like Figures 1 to 5 As shown, the hot forging device for hexagonal bolts and segment bolts of this utility model includes a hot forging part, a pushing part, and a removing part.

[0034] In this invention, the hot upsetting section includes a hot upsetting forming assembly, which is used to hot upset the head of the bolt to be processed located within the hot upsetting section to form a hexagonal shape of the bolt head; the pushing section includes a guide assembly and a pushing assembly that moves up and down along the guide assembly, the height of the pushing assembly is adjustable, the pushing section is used to support the lower end of the screw located within the hot upsetting forming assembly during the hot upsetting process, and to push the bolt after the hot upsetting is completed; the removing section includes a moving assembly that moves in the horizontal direction, which is used to remove the bolt pushed out by the pushing section.

[0035] This invention significantly improves the efficiency of hot upsetting bolt heads by highly coordinating the hot upsetting, pushing, and removal processes, reducing the time and cost of manual operation. Simultaneously, by incorporating a height-adjustable pushing assembly, it can support the lower end of bolts of different lengths during hot upsetting, thus enabling simultaneous application to both hexagonal bolts and segment bolts, avoiding frequent mold changes during these processes. Furthermore, the ejection by the pushing mechanism after hot upsetting reduces the force required to pull out the bolt, preventing wear on the bolt head and effectively improving the quality of bolt processing.

[0036] In this invention, the hot upsetting assembly is located on the upper part of the press equipment, including a punch 1 that is slidably connected to the press equipment, and a shaping sleeve 2 located below the punch 1. The shaping sleeve 2 has a vertically penetrating receiving hole for placing the bolt to be hot-set. The shaping sleeve 2 is located on the upper end face of the moving assembly, and the moving assembly has a guide hole that is coaxial with the receiving hole. The guide hole is used for the push assembly to pass through to support the lower end of the screws of different lengths and to guide and limit the up and down movement of the push assembly.

[0037] During the operation, the bolt to be heated is coaxially inserted into the shaping sleeve 2, and the lower end of the bolt is limited by the upper and lower limit of the push part. The press equipment drives the punch 1 to move downward to contact the upper end of the bolt to be heated and continuously presses the upper end of the bolt downward to form it. After the punch 1 is reset upward, the push component in the push part moves upward and drives the bolt to move upward to get out of the shaping sleeve 2. At the same time, the bolt to be heated is taken out, and the heating process is completed.

[0038] In this utility model, the push assembly is located below the shaping sleeve 2. The push assembly includes an upper base plate 5 and a lower base plate 14 arranged in parallel. The upper base plate 5 has a through guide hole, which is coaxial with the receiving hole. The upper base plate 5 and the lower base plate 14 are fixedly connected by a vertically arranged fixing rod 12. A push cylinder 13 is arranged between the upper base plate 5 and the lower base plate 14. The fixed end of the push cylinder 13 is connected to the lower base plate 14, and the movable end of the push cylinder 13 is connected to a vertically arranged push rod 9 through the lower top plate 7. The lower top plate 7 is slidably connected to the upper base plate 5 through a guide assembly. In order to enable the push rod 9 to adapt to hexagonal bolts and segment bolts of different screw lengths, the lower part of the push rod 9 is threadedly connected to the lower top plate 7.

[0039] In this utility model, the guide assembly includes a guide rod 11, the upper end of which is fixedly connected to the upper base plate 5, and the lower end of which passes through the lower top plate 7 and is slidably connected to the lower top plate 7.

[0040] In this embodiment, a vertical through hole is provided on the lower top plate 7 at the position corresponding to the push rod 9. A hexagonal nut structure is fixed coaxially with the through hole on the upper end face of the lower top plate 7. The lower part of the push rod 9 is threadedly connected to the lower top plate 7 through the hexagonal nut structure.

[0041] In this invention, the punch 1, the shaping sleeve 2 in the hot forging section and the push rod 9 in the pushing section are coaxially arranged, which can ensure the accuracy of the hot forging process and the pushing process.

[0042] In this embodiment, the hexagonal nut structure includes a push rod sleeve 8 and a fixing sleeve 6. The lower part of the push rod 9 is threadedly connected to the push rod sleeve 8. The push rod sleeve 8 is a hexagonal prism structure, and its bottom end is inserted into the fixing sleeve 6 for fixed connection. The fixing sleeve 6 has symmetrically arranged limit pins 20 on the outer periphery of its lower end, and limit pin holes are arranged at corresponding positions inside the lower top plate 7. The limit pins 20 of the fixing sleeve 6 are inserted into the limit pin holes of the lower top plate 7, and the fixing sleeve 6 is connected to the lower top plate 7. By fixing the positions of the lower top plate 7 and the fixing sleeve 6, the push rod 9 is further limited and fixed. This connection method not only increases the rigidity of the push rod 9, but also avoids the push rod 9 from shaking or shifting during the pushing process.

[0043] Due to equipment vibration, the lower part of the push rod 9 and the lower top plate 7 are prone to relative rotation, affecting processing accuracy. In this embodiment, an adjustment hole is provided at the lower part of the push rod 9, and an anti-loosening mechanism is coaxially provided in the adjustment hole. The anti-loosening mechanism includes an adjustment rod 18 inserted into the adjustment hole at the upper part. In order to keep the adjustment rod 18 relatively stationary with the adjustment hole during rotation, that is, the adjustment rod 18 can drive the push rod 9 through the adjustment hole during rotation. The cross-section of the adjustment rod 18 is a regular hexagon, and the shape of the adjustment hole is set to a regular hexagon corresponding to the adjustment rod 18. By setting the adjustment hole, the adjustment rod 18 and the push rod 9 can only slide up and down and cannot rotate relative to each other. A limit block 16 is also coaxially fixed at the lower part of the adjustment rod 18. The limit block 16 is a regular octagonal prism structure, and a limit groove 21 is provided at the position of the lower top plate 7 corresponding to the limit block 16. When the adjustment rod 18 moves downward until the limit block 16 is disengaged from the limit block 16, the adjustment rod 18 can be adjusted to keep the push rod 9 stationary. When the adjustment rod 18 is in the slot 21, the adjustment rod 18 drives the push rod 9 to rotate through the adjustment hole. Since the push rod 9 is threadedly connected to the lower top plate 7, the push rod 9 is rotated to adjust its ejection length, thus adapting to hexagonal bolts and segment bolts of different screw lengths. When the adjustment rod 18 moves upward until the limit block 16 enters the limit slot 21, the limit block 16 is an octagonal prism structure, so the limit block 16 and the lower top plate 7 cannot rotate relative to each other. That is, the lower top plate 7 cannot rotate relative to the push rod 9 to change the ejection length of the push rod 9. A return spring 17 is also provided in the adjustment hole. The upper end of the return spring 17 is connected to the bottom of the adjustment hole, and the lower end is connected to the top of the adjustment rod 18. A pull rod 19 is also provided at the lower end of the adjustment rod 18. The pull rod 19 is located at the lower end of the limit block 16 and vertically passes through the adjustment rod 18 in the horizontal direction and is connected to the adjustment rod 18.

[0044] During operation, first pull down the pull rod 19 to disengage the limiting block 16 from the limiting groove 21. Then, according to the length of the screw of the bolt to be heated, rotate the pull rod 19. The pull rod 19 drives the adjusting rod 18 to rotate, and the adjusting rod 18 drives the push rod 9 to rotate, so that the upper end face of the push rod 9 contacts the lower end face of the screw of the bolt to be heated. After the position of the push rod 9 is determined, release the pull rod 19, and the limiting block 16 returns to the limiting groove 21 to prevent the pull rod 19 from rotating, thereby ensuring that the push rod 9 will not wobble.

[0045] Example 1:

[0046] During the bolt removal process, on the one hand, to ensure the safety of the workers, the processed bolts are moved to the right side below the punch 1 before being removed; on the other hand, since the heads of the hot-forged hexagonal bolts and segment bolts are tightly squeezed with the shaping sleeve 2, they are not easy to remove. In order to reduce the force required to pull out the hot-forged bolts and avoid wear on the bolt heads, in this utility model, the lower base plate 14 of the push assembly is fixedly connected to the press equipment, and the upper end face of the upper base plate 5 of the push assembly is also provided with a horizontal guide rail 4. The moving assembly is slidably connected to the upper base plate 5 through the horizontal guide rail 4.

[0047] The moving component includes a guide plate 3 correspondingly set in the horizontal guide rail 4. The guide plate 3 is slidably connected to the upper base plate 5 through the horizontal guide rail 4. The guide plate 3 is provided with a guide hole through it. The guide hole and the receiving hole are coaxially arranged. A drive cylinder 10 is provided at the left end of the guide plate 3. The fixed end of the drive cylinder 10 is fixedly connected to the press equipment, and the movable end of the drive cylinder 10 is connected to the left side of the guide plate 3.

[0048] During operation, the push cylinder 13 moves upward, causing the push rod 9 to push the hot-forged bolt upward, making the bolt head higher than the upper end face of the shaping sleeve 2. Then, the push cylinder 13 moves downward, and the push rod 9 moves downward with the lower top plate 7. When the upper end face of the push rod 9 is lower than the lower end face of the upper bottom plate 5, the drive cylinder 10 pushes the guide plate 3 to move to the right. The worker takes out the hot-forged bolt, puts in the bolt blank to be hot-forged, the drive cylinder 10 resets, and drives the guide plate 3 to move to the left, and then completes the next hot-forging process.

[0049] Example 2:

[0050] In Embodiment 1, when the drive cylinder 10 drives the guide plate 3 to move to the right to the set position, the upper end face of the push rod 9 no longer supports the lower end face of the hot-forged bolt. That is, the upper part of the hot-forged bolt is still inside the shaping sleeve 2 and is not easy to remove. In order to enable the push assembly to drive the push rod 9 to move upward again after the drive cylinder 10 drives the guide plate 3 to move to the right to the set position until the upper part of the hot-forged bolt is removed from the shaping sleeve 2 and maintained at the set height, so that the bolt can be easily clamped.

[0051] In this utility model, a horizontally extending slide rail is provided at the lower part of the press equipment. The lower base plate 14 in the push assembly is slidably connected to the press equipment in the left and right directions through the slide rail. The moving assembly includes a guide plate placement groove provided on the upper surface of the upper base plate 5. The guide plate 3 is placed in the guide plate placement groove to achieve a fixed connection between the upper base plate 5 and the guide plate 3. The guide plate 3 is provided with a guide hole through it. The guide hole and the receiving hole are coaxially arranged. A drive cylinder 10 is provided at the left end of the guide plate 3. The fixed end of the drive cylinder 10 is fixedly connected to the press equipment, and the movable end of the drive cylinder 10 is connected to the left side of the guide plate 3.

[0052] During operation, the movable end of the drive cylinder 10 pushes the guide plate 3 to the right. Since the guide plate 3 is fixedly connected to the upper base plate 5, the guide plate 3 drives the upper base plate 5 and the lower base plate 14 to move to the right, moving them away from the position below the punch 1. The push cylinder 13 moves upward, causing the push rod 9 to push the hot-forged bolt upward. The operator removes the hot-forged bolt. At this time, the push cylinder 13 moves downward, and the operator places the bolt blank to be hot-forged. The drive cylinder 10 resets, driving the upper base plate 5 and the lower base plate 14 to move to the left, and then the next hot-forging process is completed. The guide plate 3 can further increase the length of the hot-forged bolt that can be processed. That is, after the guide plate 3 is installed, after the bolt to be hot-forged is placed in the shaping sleeve 2, as long as the lower end face of the bolt to be hot-forged is not lower than the lower end face of the guide plate 3, the hot-forging and removal of the bolt can be completed by this utility model.
