Description

Technical Field

[0001] This utility model specifically relates to the field of parts forging technology, and more specifically to a forging device for crane connecting arm parts. Background Technology

[0002] The connecting boom is one of the key components of a crane, mainly used to connect different parts of the crane, such as the tower and the boom, or the boom and the counterweight boom. The basic function of the connecting boom is to connect the various parts of the crane together, so that the crane forms a complete working system. It also provides support for other components, ensuring that the relative positions and angles between the components are kept within a suitable range. Therefore, the boom connecting boom is generally supported by high-strength metal materials, and the manufacturing process requires the metal profiles to be continuously hammered and forged using a forging machine to remove surface impurities, making the internal structure more compact.

[0003] However, in practice, it has been noted that most forging machines are currently pneumatically driven, using a forging hammer to forge the workpiece. During the forging process, workers need to use extended special clamps to continuously move the workpiece to ensure more uniform forging. However, the metal shavings that fall off during forging need to be thrown outwards. Due to the high temperature of the metal shavings, workers nearby are easily burned by the flying metal shavings, resulting in poor safety. Furthermore, the crane's connecting arm is large, and manual force alone cannot quickly adjust the position of the workpiece during forging, leading to different forging times at different locations on the workpiece. This, in turn, affects the quality of the finished product and results in uneven forging. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a forging device for crane connecting arm accessories, including a forging machine and a workbench. The forging machine includes a base 1, a supporting shell 6 welded to the end of the base 1, a forging hammer 2 movably connected above the supporting shell 6, and an anvil seat 7 fixedly connected to the base 1 corresponding to the lower end of the forging hammer 2 away from the supporting shell 6.

[0033] A rotating cam is movably connected to the supporting housing 6, and the rotating cam contacts the bottom of the forging hammer 2. The rotating cam is also provided with a drive shaft, and the two ends of the drive shaft are movably connected to the supporting housing 6 through bearings.

[0034] The workbench includes a forging table 8 that is movably fitted with an anvil seat 7. A sliding clamp seat 9 is slidably connected to the forging table 8. An automatic displacement component 10 is also provided on the side of the forging table 8, and the automatic displacement component 10 is connected to the pulley 11 for transmission.

[0035] In this embodiment, the forging table 8 includes a placement table 81 placed on the anvil seat 7. The bottom of the placement table 81 is fixedly connected to a bottom support seat 84. A positioning slide rod 85 is installed on the inner side of the bottom support seat 84, and the bottom of the bottom support seat 84 is provided with universal wheels 86 in a rectangular array.

[0036] Furthermore, the anvil base 7 is integrally provided with a positioning sleeve corresponding to the positioning slide rod 85, and the positioning slide rod 85 passes through the positioning sleeve and is slidably connected to the positioning sleeve.

[0037] More specifically, the placement platform 81 has sliding grooves on both sides, and each sliding groove has a sliding rod 83, with both ends of the sliding rod 83 fixedly connected to the placement platform 81.

[0038] In this embodiment, an end baffle 82 is integrally provided above one end of the placement platform 81, and a sliding clamping seat 9 is provided above the other end of the placement platform 81. The sliding clamping seat 9 includes a movable baffle 91 that fits against the upper part of the placement platform 81.

[0039] In this embodiment, both sides of the movable baffle 91 are integrally provided with connecting sliders 92 that correspond to the sliding grooves on both sides of the placement platform 81, and the connecting sliders 92 are sleeved on the outside of the sliding rod 83, and the sliding rod 83 and the connecting sliders 92 are in sliding engagement.

[0040] Furthermore, the side of the connecting slider 92 is also provided with a compression spring 93, and the compression spring 93 is sleeved on the outside of the sliding rod 83.

[0041] In this embodiment, the bottom support 84 is provided with an automatic displacement component 10 on the side near the support housing 6. The automatic displacement component 10 includes a threaded fixing rod 101 that is fixedly connected to the bottom support 84.

[0042] More specifically, the outer side of the threaded fixing rod 101 is sleeved with a drive turntable 102, wherein the outer side of the drive turntable 102 is integrally provided with gear teeth, the inner side of the drive turntable 102 is provided with a threaded hole, and the threaded fixing rod 101 is threadedly engaged with the drive turntable 102.

[0043] The side of the drive turntable 102 is movably connected to a positioning bracket 106 via a bearing, and the end of the positioning bracket 106 away from the drive turntable 102 is fixedly connected to the support housing 6 by bolts.

[0044] In this embodiment, the drive turntable 102 is also provided with a fixed bracket 103 on the side near the support housing 6. The end of the fixed bracket 103 is fixedly connected to the support housing 6, and the end of the fixed bracket 103 away from the support housing 6 is movably connected to the intermediate gear 104, and the intermediate gear 104 meshes with the drive turntable 102.

[0045] In this embodiment, a drive gear 105 is fixedly connected to the side of the pulley 11 away from the supporting housing 6, and the drive gear 105 is coaxially arranged with the pulley 11. The drive gear 105 is located on the side of the intermediate gear 104 away from the drive turntable 102, and the drive gear 105 and the intermediate gear 104 mesh with each other.

[0046] By adopting the above technical solution, the workpiece is placed on the forging table 8. The workpiece is positioned by the compression between the end baffle 82 and the sliding clamping seat 9. Then, when the pulley 11 drives the rotating cam inside the supporting housing 6 to rotate, the drive gear 105 will rotate with the pulley 11. Through the meshing of the intermediate gear 104 with the drive turntable 102 and the drive gear 105, the drive turntable 102 is rotated. Through the threaded engagement between the drive turntable 102 and the threaded fixing rod 101, the threaded fixing rod 101 drives the forging table 8 to move. At the same time, the rotating cam drives the forging hammer 2 to swing back and forth, continuously hammering and forging the workpiece on the forging table 8. The workpiece is automatically moved during the forging process, thereby reducing the labor intensity during forging.

[0047] In this embodiment, the forging machine further includes a buffer mechanism 3 fixedly connected to the upper part of the support shell 6. The buffer mechanism 3 includes an extension column that is inclinedly welded to the side of the support shell 6. A telescopic rod is movably connected to one end of the extension column away from the support shell 6. A shock-absorbing spring is installed on the telescopic rod, and the other end of the telescopic rod is movably connected to the forging hammer 2 through a pin.

[0048] More specifically, when the protrusion of the rotating cam contacts the forging hammer 2, it lifts the forging hammer 2 up. When the protrusion of the rotating cam does not contact the forging hammer 2, the shock-absorbing spring pushes the forging hammer 2 to move by extending and retracting, causing the end of the forging hammer 2 to fall and hammer the workpiece for forging.

[0049] In this embodiment, a drive motor 5 is fixedly connected to the base 1, and a drive pulley is fixedly connected to the end of the drive motor 5. A transmission mechanism 4 is also provided between the drive motor 5 and the support housing 6. The transmission mechanism 4 includes a support plate fixedly connected to the base 1.

[0050] In this embodiment, a synchronous pulley is movably connected to the side of the supporting plate. The synchronous pulley has a large pulley and a small pulley arranged coaxially. The large pulley is connected to the drive pulley at the end of the drive motor 5 via a conveyor belt, and the small pulley is connected to the belt pulley 11 via a conveyor belt.

[0051] More specifically, the drive motor 5 drives the synchronous pulley to rotate through the transmission connection between the drive pulley and the transmission belt. The small pulley in the synchronous pulley drives the belt pulley 11 to rotate through the transmission belt, thereby driving the rotating cam inside the supporting housing 6 to rotate.

[0052] In this embodiment, the top of the anvil seat 7 contacts the placement platform 81, and the anvil seat 7 supports the placement platform 81 to prevent the placement platform 81 from bending due to long-term impact.

[0053] In this embodiment, the end baffle 82 is inclined on the side near the movable baffle 91 and the movable baffle 91 is inclined on the side near the end baffle 82, and the workpiece is clamped by the inclined surfaces of the end baffle 82 and the movable baffle 91.

[0054] The working principle of this utility model is as follows: In use, the workpiece is first placed on the placement table 81, with one end of the workpiece fitting against the end baffle 82. The compression spring 93 pushes the connecting slider 92 to slide outside the sliding rod 83, causing the moving baffle 91 to move closer to the end baffle 82. The workpiece is clamped by the compression between the moving baffle 91 and the end baffle 82. Then, the drive motor 5 drives the pulley 11 to rotate through the transmission mechanism 4. Since the pulley 11 is coaxially arranged with the rotating cam and the drive gear 105 inside the supporting housing 6, it drives the rotating cam and the drive gear 105 to rotate simultaneously. The wheel and the buffer mechanism 3 work together to make the end of the forging hammer 2 above the placement table 81 swing back and forth to forge the workpiece. At the same time, the drive gear 105 meshes with the intermediate gear 104 to drive the drive turntable 102 to rotate outside the positioning bracket 106. The rotating drive turntable 102 is threadedly engaged with the threaded fixing rod 101, which drives the placement table 81 to move slowly through the bottom support seat 84. This causes the workpiece placed on the placement table 81 to move continuously. During the movement, the forging hammer 2 is used to forge the workpiece. The worker does not need to hold the clamp to move the workpiece for forging, thus reducing the labor intensity.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
