Description

Technical Field

[0001] This utility model relates to an improvement in the forging technology of ferrous liquid metal, specifically a truss-type lifting device for forging ferrous liquid metal. Background Technology

[0002] Forging ferrous metals is a technical challenge. Traditionally, ferrous metals are mainly produced by casting, which involves melting ferrous metals composed of iron, manganese, chromium, etc., and then casting them into a designated mold. However, this method makes it difficult to further improve the density of ferrous metals in the solid state and to further improve their wear resistance.

[0003] Therefore, in response to this problem, the applicant adopts a forging production method for ferrous metals, that is, by using a large-tonnage press to press the liquid metal in the mold into a solid state under high pressure during the transformation process through mold closing, thereby improving the metal density of ferrous metals in the solid state and thus effectively improving the wear resistance of ferrous metals.

[0004] However, due to the heavy weight of the lower mold containing liquid ferrous metal, it is often necessary to use a chain hoist to lift the lower mold during the transportation process. The installation and disassembly of the hook of the hoist and the lower mold, as well as manual operation, make the transportation speed slow and the movement trajectory irregular, resulting in low production efficiency and an unsafe production environment. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, this utility model provides a truss-type lifting device for forging ferrous liquid metal. By using a truss in conjunction with a railcar and a corresponding lifting device design, the lower mold can be transported and rotated, thereby effectively improving the efficiency and safety of the lower mold transport process.

[0006] The technical solution adopted by this application to solve its technical problem is: a truss-type lifting device for forging ferrous liquid metal, including a truss, a first track, the first track being disposed on the truss and including an upper fixed frame and a lower fixed frame, the upper fixed frame being slidably engaged with the first track through a roller assembly, the lower fixed frame being slidably engaged with the upper fixed frame in the vertical direction through a guide module, and also including a boom module, the lower fixed frame having second tracks on both sides, the boom module being slidably engaged with the second tracks through a roller assembly, the boom modules on both sides being driven by a bidirectional screw module, the bidirectional screw module being mounted on the lower fixed frame, and the bottom of the boom module having a clamp with a rotation function.

[0007] Preferably, the boom module includes a boom base, an upper boom, a lower boom, and the boom base is slidably engaged with the track of the lower fixed frame via roller sets on both sides. The boom base, upper boom, and lower boom are connected in sequence.

[0008] Preferably, the upper and lower booms are hollow structures, with a motor module inside the lower boom, and the output end of the motor module passing through the lower boom and connected to the clamp.

[0009] Preferably, the weight of the upper boom does not exceed the sum of the weights of the lower boom, the motor module, and the clamp.

[0010] Preferably, the lower boom is also provided with several limiting blocks that can abut against the clamps.

[0011] Preferably, the motor module is installed between the upper boom and the lower boom.

[0012] Preferably, the fixture includes a rotating shaft and a chuck. The rotating shaft passes through the lower boom, and the output shaft of the motor module is linked to the rotating shaft via chain drive. The chuck is installed at the end of the rotating shaft and located on the outer surface of the lower boom.

[0013] The beneficial effects of this utility model are as follows: The truss-type lifting device for ferrous liquid metal forging of this utility model, through the cooperation between the upper fixed frame, the lower fixed frame and the boom module, enables the clamp to move up and down, approach each other and rotate, and the above actions can be realized stably. The design of the boom module ensures strength while preventing excessive weight loss. It can prevent the lower mold carrying ferrous metal from falling off or shifting position during transportation, thereby greatly improving the production safety and efficiency of ferrous liquid metal forging.

[0019] This utility model discloses a truss-type lifting device for forging ferrous liquid metal, comprising a truss 1 and a track 2. The track 2 is mounted on the truss 1, which is generally located above a track trolley 11. The track trolley 11 is used to mount a lower mold containing liquid ferrous metal or forged solid ferrous metal. The lifting device also includes an upper fixed frame 3 and a lower fixed frame 4. The upper fixed frame 3 is slidably engaged with the track 2 via a roller assembly 5. The track 2 is mounted on the truss 1. When the track trolley 11 moves to a designated position, the upper fixed frame 3 is driven to move above the track trolley 11 on the truss 1 by driving the roller assembly 5. The lower fixed frame 4 is slidably engaged with the upper fixed frame 3 in the vertical direction via a guide module. The guide module includes several guide columns 10 and a drive mechanism. The guide module drives the lower fixed frame 4 to descend, thereby causing the boom modules 6 located on both sides of the lower fixed frame 4 to descend until the height of the clamp 9 is consistent with the height of the upper and lower molds of the track trolley.

[0020] The lower fixed frame 4 has two rails 7 on both sides. The boom module 6 is slidably engaged with the rails 7 via the roller assembly 5. The boom modules 6 on both sides are driven by the bidirectional screw module 8. That is, the roller assembly 5 on the upper fixed frame 3 is the driving wheel with driving function, and the roller assembly 5 on the lower fixed frame 4 is the driven wheel, which plays a lateral guiding role. The two boom modules 6 on both sides are driven to move closer and further apart by the bidirectional screw module 8. The bidirectional screw module 8 is installed on the lower fixed frame 4, and the screw is screwed to the boom module 6, thereby realizing the stable movement of the boom module 6.

[0021] The boom module 6 includes a boom base 61, an upper boom 62, and a lower boom 63. The boom base 61 is slidably connected to the track 7 of the lower fixed frame 4 via roller sets 5 on both sides. The boom base 61, upper boom 62, and lower boom 63 are connected sequentially. The upper boom 62 mainly serves to strengthen the support and is generally made of angle steel as connecting parts. Sheet metal parts are connected between the angle steels for protection and reinforcement.

[0022] The upper boom 62 is generally lightweight and mainly provides stable connection and support for the lower boom 63. Therefore, the weight of the upper boom 62 should not exceed the total weight of the lower boom 63, the motor module 64, and the clamp 9. Otherwise, the weight of the entire boom module 6 will be too heavy, and it may deform when lifting small molds containing ferrous metal. The motor module 64 is installed between the upper boom 62 and the lower boom 63. A fixing plate is provided between the upper boom 62 and the lower boom 63 for installing the motor module 64. Several sprockets are provided on the output shaft of the motor module 64. The clamp 9 includes a rotating shaft 91 and a chuck 92. The rotating shaft 91 passes through the lower boom 63 and rotates with the housing of the lower boom 63. The output shaft of the motor module 64 is linked to the rotating shaft 91 through sprockets and chain drive. Several sprockets are also sleeved on the rotating shaft 91. There are generally two to three chains. The chuck 92 is installed at the end of the rotating shaft 91 and is located on the outer surface of the lower boom 63. Generally, the chuck 92 and the rotating shaft 91 are integral cast iron parts. The movement process of the chuck 92 is mainly divided into the following steps: the lower fixed frame 4 descends together with the boom module 6, and then the boom module moves closer to each other on the lower fixed frame 4 so that the chuck 92 can be inserted into the small mold on the track trolley, thereby realizing the rise and movement of the lower mold. Then, the motor module 64 drives the chuck 92 to flip the small mold. In order to stabilize the tilt angle when the lower mold flips, the lower boom 63 is provided with a limiting block 65 that can abut against the clamp 9, thereby limiting the tilt angle of the chuck 92 and preventing the lower mold from falling directly off the clamp 9 due to excessive tilt angle.

[0023] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
