Description

Technical Field

[0001] This utility model relates to the field of casting production equipment technology, and in particular to a hanger for shot blasting castings. Background Technology

[0002] Industrial casting generally involves pouring liquid metal into a casting cavity that conforms to the shape of the part. After cooling and solidification, a part or blank is obtained. Castings obtained through the casting process need to be shot blasted. High-speed shot is used to continuously impact the surface of the casting to remove residual stress and improve the fatigue life of the casting. At the same time, it can also improve the surface roughness of the workpiece. Currently used shot blasting machines generally hang the castings directly on hooks inside the shot blasting machine.

[0003] In existing technology patent CN205222443U, a shot blasting hanger for cleaning castings is disclosed. The hanger has four support rods on a hook support, with multiple casting hooks evenly spaced on the lower surface of each support rod. This doubles the number of workpieces that can be hung at a time, fully utilizing the space inside the shot blasting chamber and improving shot blasting efficiency. The casting hooks are connected to the support rods via chains, making it easier to hang castings on them compared to using rigid casting hooks directly. Furthermore, the shot blasting hanger is easier to store when not in use. Additionally, a first lifting lug and a second lifting lug are symmetrically arranged on two support rods aligned in a straight line. During the transport of the shot blasting hanger to the shot blasting chamber by the crane, the first and second lifting lugs can be used first. This allows the hooks inside the shot blasting chamber to directly hang the central hook, providing an alternating hook process compared to having only one central hook, further improving the efficiency of the shot blasting hanger.

[0004] However, in the existing methods described above, the spacing between the casting hooks cannot be adjusted, resulting in the current method only being able to adapt to castings of the same specification and size, thus limiting its applicability. Utility Model Content

[0005] The purpose of this utility model is to provide a hanger for shot blasting of castings, which aims to solve the technical problem that the spacing between the casting hooks in the prior art cannot be adjusted, resulting in the existing technology only being able to adapt to castings of the same specification and size, and thus having a limited range of applications.

[0006] To achieve the above objectives, this utility model employs a casting shot blasting hanger, comprising a support, a central hook, multiple casting hooks, multiple chains, and multiple sets of movable modules. The central hook is fixedly connected to the support and is located above the support. The support has multiple movable slots and multiple insertion slots. The multiple sets of movable modules are all movably connected to the support. Each chain is connected to a corresponding movable module, and each casting hook is connected to a corresponding chain.

[0007] The movable module includes a movable block, a connecting plate, two sliding rods, two plug-in plates, a pull rod, and two supporting springs. The movable block is movably connected to the bracket and located within the movable groove. The connecting plate is fixedly connected to the movable block and located above the movable block. The connecting plate has two grooves. Both sliding rods are movably connected to the connecting plate and pass through it. Each plug-in plate is fixedly connected to the corresponding sliding rod and is adapted to the groove and the plug-in groove respectively. Each pull rod is fixedly connected to both sliding rods. Both ends of each supporting spring are fixedly connected to the connecting plate and the pull rod respectively and are respectively sleeved on the outside of the sliding rod.

[0008] The active module further includes a protective cover and a connector. The protective cover is located above the connecting plate, and the connector is connected to the protective cover and the connecting plate respectively.

[0009] The connector includes a first magnetic ring and a second magnetic ring. The first magnetic ring is fixedly connected to the connecting plate and is located on the connecting plate. The second magnetic ring is fixedly connected to the protective cover and is located below the protective cover. The first magnetic ring and the second magnetic ring are magnetically attracted to each other.

[0010] The active module further includes two plug-in arc blocks, each of which is fixedly connected to the corresponding plug-in plate and is located below the plug-in plate.

[0011] The shot blasting hanger for castings also includes a fixed lifting ring, which is fixedly connected to the bracket and located below the bracket.

[0012] This utility model discloses a casting shot blasting hanger. The casting hooks at the bottom of the bracket are used to hang castings. When larger castings or castings of different sizes need to be hung, the spacing between the casting hooks is adjusted accordingly. By pulling the pull rod on the connecting plate, the pull rod, through the sliding rod, causes the insertion plate to disengage from the insertion slot of the bracket and enter the groove. Simultaneously, the pull rod stretches the holding spring. Then, the connecting plate is moved, causing the movable block to move within the movable groove of the bracket. The casting hooks move accordingly. After the connecting plate has been moved, the pull rod is released, and the holding spring rebounds, causing the insertion plate to enter another insertion slot of the bracket, thus completing the adjustment of the connecting plate. Using this method, the position of the casting can be adjusted as needed, allowing for the hanging of castings of different sizes or larger sizes. This enables the adjustment of the spacing between the casting hooks, adapting to castings of various sizes and greatly increasing its applicability. Attached Figure Description
