Description

Technical Field

[0001] This application belongs to the technical field of aluminum profile production equipment, specifically a hoisting tool and hoisting device for aluminum profile production. Background Technology

[0002] Aluminum profiles are products obtained by extruding aluminum ingots through a die under the action of a press. Before extrusion, in order to prevent the ingot from directly contacting the die and causing a sudden drop in temperature, which would affect the appearance quality of the aluminum profile, the die needs to be fully preheated in a heating furnace.

[0003] The mold is heated to 420℃ to 480℃ and should not be touched directly by hand. For lightweight, small molds, operators typically use special pliers to remove them from the furnace and install them onto the extruder. For large molds, which may weigh hundreds of kilograms, lifting equipment is required to hoist them from the furnace onto the extruder. To facilitate hanging the mold on the hook, threaded holes are machined into the mold, and lifting rings are detachably installed within these holes.

[0004] The existing mold hoisting process involves the following steps: First, the lifting ring with studs is installed into the threaded hole of the mold. Then, the hoisting equipment is operated to hook the hook onto the lifting ring, lifting the mold from the heating furnace. Finally, the lifting device is used to transfer the mold above the extruder, lowering the mold to the installation position, and removing the lifting ring from the mold. The lifting ring is typically made of steel, which has excellent thermal conductivity. However, because the standard lifting ring is relatively short, manual removal of the ring may result in burns from touching the mold, requiring the wearing of special heat-resistant gloves, which is inconvenient. Utility Model Content

[0005] Based on the above-mentioned technical problems, this application provides a hoisting tool and hoisting device for aluminum profile production, so as to solve the technical problems of inconvenience in operation and potential burns when hoisting molds in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, this application provides a hoisting fixture for aluminum profile production, comprising: A lifting component for connecting to a lifting rope, wherein the lower part of the lifting component is hollow and forms a mounting cavity, and the bottom of the mounting cavity has a through mounting hole; and A connector includes a limiting part and a connecting part. The limiting part is housed in the mounting cavity and rotates with the inner wall of the mounting cavity. The connecting part is located below the limiting part, passes through the mounting hole, and has a connecting end at its bottom. The connecting end has an external thread and is used to thread into a threaded hole on the mold. The length of the connecting part is 100-500mm.

[0007] In one possible implementation, the lifting fixture for aluminum profile production further includes a thrust bearing disposed between the limiting portion and the bottom wall of the mounting cavity.

[0008] In one possible implementation, the side wall of the lifting component is provided with a hinge seat, and the hinge seat is movably connected to a support rod, the length of which is greater than the length of the connecting part.

[0009] In one possible implementation, a handle is provided at the end of the support rod away from the hinge seat.

[0010] In one possible implementation, the hinged seat is further provided with a limit rod below the position where it connects with the support rod, and the limit rod is used to form a stop with the support rod.

[0011] In one possible implementation, the side wall of the lifting member is provided with a retaining member located above the hinge seat, the retaining member having a slot for accommodating the support rod.

[0012] In one possible implementation, the connecting portion is provided with a heat insulation sleeve at one end adjacent to the limiting portion, the heat insulation sleeve being located below the lifting member, and the heat insulation sleeve being fixedly connected to the connecting portion.

[0013] Compared with the prior art, the advantages of the lifting fixture for aluminum profile production provided in this application are: The lifting fixture for aluminum profile production provided in this application includes a lifting component and a connecting component. The lifting component is connected to a lifting rope, and the connecting component is rotatably fitted with the lifting component. The lower end of the connecting component extends into an installation cavity and is provided with a connecting end, which is used for detachable connection with the mold. In use, the connecting component is directly rotated to screw the connecting end into the threaded hole of the mold. The lifting device is then used to lift the mold to the mold installation position on the extrusion press. The connecting component is then rotated again to separate the connecting end from the mold. Compared with existing mold lifting methods, in terms of operational convenience, the lifting fixture provided in this application replaces the existing separate connection form of lifting ring and hook. Rotating the connecting component is sufficient to achieve connection and separation with the mold, making installation and disassembly simpler and more convenient. In terms of operational safety, the length of the connecting component is longer than that of existing ordinary lifting rings. When rotating the connecting component, it is less likely to touch the mold, and the heat from the mold is less likely to be conducted to the connecting component, which helps to reduce the probability of burn accidents.

[0014] Secondly, this application provides a hoisting device for aluminum profile production, comprising: A hanger having a horizontally arranged crossbeam; A lifting device, movably mounted on the crossbeam, the lifting device having a lifting rope; and In any of the above implementations, the lifting fixture for aluminum profile production is connected to the lifting rope.

[0015] In one possible implementation, the lifting device is an electric hoist.

[0016] In one possible implementation, the crossbeam is rotatably mounted on the hanger about a vertical axis.

[0017] The lifting device for aluminum profile production provided in this application adopts any of the above-mentioned implementation methods and has the same technical effect, which will not be described in detail here. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Please refer to the following: Figures 1 to 5 The following describes the hoisting fixtures and hoisting devices for aluminum profile production provided in the embodiments of this application.

[0026] Please see Figures 1 to 4In a first aspect, embodiments of this application provide a hoisting fixture for aluminum profile production, including a hoisting component 10 and a connecting component 20. The hoisting component 10 is used to connect with a hoisting rope 61. The lower part of the hoisting component 10 is hollow and forms an installation cavity. A through installation hole is opened at the bottom of the installation cavity. The connecting component 20 includes a limiting part 21 and a connecting part 22. The limiting part 21 is housed in the installation cavity and rotates with the inner wall of the installation cavity. The connecting part 22 is located below the limiting part 21. The connecting part 22 passes through the installation hole and has a connecting end 221 at its bottom. The connecting end 221 has an external thread and is used to thread into a threaded hole on the mold 70. The length of the connecting part 22 is 100-500mm.

[0027] Compared with the prior art, the beneficial effects of the lifting fixture for aluminum profile production provided in this application embodiment are: The lifting fixture for aluminum profile production provided in this embodiment includes a lifting member 10 and a connecting member 20. The lifting member 10 is connected to a lifting rope 61, and the connecting member 20 is rotatably engaged with the lifting member 10. The lower end of the connecting member 20 extends out of an installation cavity and is provided with a connecting end 221, which is used for detachable connection with the mold 70. In use, the connecting member 20 is directly rotated to screw the connecting end 221 into the threaded hole of the mold 70, and the lifting device 60 is used to lift the mold 70 to the mold 70 installation position on the extrusion press. Then, the connecting member 20 is rotated to separate the connecting end 221 from the mold 70.

[0028] Compared to existing methods of hoisting molds 70, the hoisting fixture provided in this embodiment replaces the existing separate connection of lifting ring and hook in terms of ease of operation. The connection and separation with the mold 70 can be achieved simply by rotating the connecting piece 20, making installation and disassembly simpler and more convenient. In terms of operational safety, the connecting piece 20 is longer than the existing ordinary lifting ring, making it less likely to touch the mold 70 when rotating it, and the heat from the mold 70 is less likely to be conducted to the connecting piece 20, thus helping to reduce the probability of burns.

[0029] In this embodiment, both the lifting member 10 and the connecting member 20 can be made of materials such as carbon steel or cast iron, which have high structural strength and are not easily damaged. The lifting member 10 has a mounting cavity for accommodating the limiting part 21 of the connecting member 20.

[0030] The lifting component 10 can be a split structure. For example, in one specific embodiment, the lifting component 10 consists of a sleeve and a blocking plate assembly. The top of the sleeve is open and forms a mounting cavity and a mounting hole. The limiting part 21 is rotatably engaged with the inner wall of the sleeve. After the connecting member 20 is installed into the sleeve, the blocking plate is used to close the opening at the top of the sleeve and connects the blocking plate to the lifting rope 61 of the lifting device 60. The blocking plate and the sleeve can be fixed by means of threaded connection, welding, etc. The blocking plate can be raised and lowered together with the lifting rope 61. The connection method between the lifting rope 61 and the blocking plate is prior art and will not be described in detail here.

[0031] The connector 20 includes a limiting part 21 and a connecting part 22. The limiting part 21 is cylindrical with a large diameter, while the connecting part 22 is a thin rod with a small diameter and a long length. The lower end of the connecting part 22 is threaded into a threaded hole in the mold 70. The tensile strength of the connector 20 should be able to withstand the weight of the mold 70. The limiting part 21 and the connecting part 22 can be integrally formed or connected as a single unit by welding, bolting, or other methods.

[0032] To further improve safety, a heat insulation sleeve can be provided at one end of the connecting part 22 near the limiting part 21. The heat insulation sleeve is annular and is fitted around the outer periphery of the connecting part 22 and located below the lifting member 10. The heat insulation sleeve is fixedly connected to the connecting part 22. The operator holds the heat insulation sleeve and rotates the connecting member 20. The heat insulation sleeve can be made of materials with poor thermal conductivity, such as rubber or wood.

[0033] To reduce the rotational resistance of the connector 20, the lifting fixture for aluminum profile production also includes a thrust bearing 30. The thrust bearing 30 is located between the limiting part 21 and the bottom wall of the mounting cavity. The thrust bearing 30 uses cylindrical rollers or balls as rolling elements, which can withstand the axial pressure from the connector 20 and reduce the rotational resistance of the connector 20.

[0034] Because the lifting rope 61 is a flexible rope, and the mold 70 has a large mass and inertia, the mold 70 is prone to swaying when the lifting device 60 starts and stops. To prevent the mold 70 from swaying significantly when moving, please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The lifting component 10 has a hinge seat 11 on its side wall, and a support rod 40 is movably connected to the hinge seat 11. The support rod 40 can be made of hollow steel pipe. For easy gripping, a handle 41 is provided at the end of the support rod 40 away from the hinge seat 11.

[0035] When the lifting device 60 moves the mold 70 from the heating furnace to the extruder, the operator uses one hand to operate the remote control 62 of the lifting device 60 to control its movement, and the other hand holds the handle 41. The mold 70 is supported by the support rod 40 to prevent it from shaking significantly. The length of the support rod 40 should be greater than the length of the connecting part 22, so that the operator is further away from the mold 70 when holding the support rod 40, which is safer.

[0036] To prevent the support rod 40 from colliding directly with the mold 70 after it is released, the hinge seat 11 is provided with a limit rod 111 below the connection position between itself and the support rod 40. The limit rod 111 is used to form a stop with the support rod 40, and the limit rod 111 ensures that the angle between the support rod 40 and the lifting rope 61 does not exceed 150°.

[0037] When not in use, in order to store the support rod 40, the side wall of the lifting member 10 is provided with a retaining member 12. The retaining member 12 is located above the hinge seat 11. The retaining member 12 has a slot for accommodating the support rod 40. When the support rod 40 is rotated upward into the slot, the slot uses its own deformation to generate elasticity to hold and fix the support rod 40, which can save space.

[0038] Please see Figure 5 and Figure 6 Secondly, this application provides a hoisting device for aluminum profile production, including a hanger 50, a lifting device 60, and the aforementioned hoisting fixture for aluminum profile production. The hanger 50 is fixed to the ground and serves as a support. The hanger 50 has a horizontally arranged crossbeam 51. The lifting device 60 is movably mounted on the crossbeam 51 and has a lifting rope 61. The lifting device 60 is connected to a remote control 62, which can be used to perform operations such as translation of the lifting device 60 and lifting and lowering of the lifting rope 61. The lifting component 10 of the hoisting fixture for aluminum profile production is connected to the lifting rope 61.

[0039] There are no restrictions on the specific type and model of the lifting device 60; suitable products can be directly purchased from the market. Specifically, the lifting device 60 can be an electric hoist, controlled by a remote control 62 to move along the crossbeam 51 or to raise and lower the lifting rope 61. When the horizontal position of the crossbeam 51 needs adjustment, the crossbeam 51 is rotatably mounted on the hanger 50 around its vertical axis. The crossbeam 51 can be rotated using a geared motor or other rotary drive components. The shape, size, and installation method of the crossbeam 51 are existing technologies and will not be elaborated here; users can set them according to their actual needs.

[0040] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
