Description

Technical Field

[0001] The utility model relates to the technical field of casting manufacturing, in particular to a multi-station bracket. Background Art

[0002] Heat treatment of castings is an important means to improve the properties of castings and enhance the performance of castings. Annealing, normalizing, quenching and tempering are the "four fires" in the overall heat treatment. Quenching is the operation of rapidly cooling the workpiece in a quenching medium such as water, oil or other inorganic salts, organic aqueous solutions, etc. after heating and keeping warm. For large batches of small-volume castings, it is necessary to ensure that the castings enter and exit the quenching furnace and the quenching medium at the same time, so that the quality of batch castings remains consistent. However, some existing small-volume single-layer brackets can only carry a small number of castings. If you want to mass-produce castings, you need to manually carry them multiple times, and the single-layer bracket has a low utilization rate of the space in the oven, and cannot achieve the best heat utilization effect. Summary of the invention

By arranging a supporting device, the number of castings quenched each time is increased, and the quality of castings quenched in the same batch can be guaranteed to be the same. By arranging a supporting device, the brackets can be stacked and used, and the support plate can disperse the pressure of the upper bracket on the lower bracket, so that the lower bracket will not collapse.

[0004] To achieve the above-mentioned purpose, the utility model provides a multi-station bracket, including a supporting device, a supporting device is fixedly connected to the top of the supporting device, a handle is provided in the middle of the supporting device, the supporting device includes a supporting plate, a supporting groove is provided on the upper surface of the supporting plate, a through hole is provided in the middle of the supporting plate, and the support plate and the handle are welded.

[0020] Embodiment 1

[0021] like Figure 1 As shown, the utility model provides a multi-station bracket, including a supporting device, a supporting device is fixedly connected to the upper part of the supporting device, and a handle 7 is provided in the middle of the supporting device, and the handle 7 is used to provide support for the staff to lift the bracket. The supporting device is used to place castings, and the supporting device is used to enable the brackets to be stacked for use, so that more castings can be quenched each time, the utilization rate of the drying furnace is increased, and the quality of castings quenched in the same batch is the same.

[0022] The supporting device includes an outer inner supporting ring 2, and a plurality of outer inner supporting rings 2 are provided. The outer inner supporting rings 2 are connected by an inner connecting rod 4, and the outer inner supporting rings 2 and the inner connecting rod 4 are welded. An outer supporting ring 1 is provided outside the outer inner supporting ring 2, and the outer inner supporting ring 2 is coaxially arranged with the outer supporting ring 1. The number of the outer inner supporting rings 2 is the same as the number of the outer supporting rings 1. The outer supporting rings 1 are connected by an outer connecting rod 5, and the outer supporting ring 1 and the outer connecting rod 5 are welded. The outer inner supporting ring 2 and the outer supporting ring 1 can support the casting so that all parts of the casting can be quenched. The welding method can make the connection between the structures stronger.

[0023] The outer inner support ring 2 is connected to the outer support ring 1 via a connecting column 3 , and the connecting column 3 and the outer inner support ring 2 as well as the connecting column 3 and the outer support ring 1 are welded. The connecting column 3 serves to connect the outer inner support ring 2 and the outer support ring 1 .

[0024] The inner connecting rod 4 and the outer connecting rod 5 are arranged opposite to each other, and the connecting column 3 is welded between the welding point between the inner connecting rod 4 and the outer inner supporting ring 2 and the welding point between the outer connecting rod 5 and the outer supporting ring 1. Two upper and lower connecting columns 3 are welded between each inner connecting rod 4 and each outer connecting rod 5.

[0025] The supporting device includes a supporting plate 6, which plays a supporting role. A supporting groove 8 is provided on the upper surface of the supporting plate 6, and the size of the groove of the supporting groove 8 is the same as the size of the outer inner supporting ring 2. The outer inner supporting ring 2 can be placed in the supporting groove 8, so that the upper bracket can stand firmly on the lower bracket. If the supporting plate 6 is not used, directly stacking the two brackets will cause the outer inner supporting ring 2 and the outer supporting ring 1 of the lower bracket to be subjected to excessive pressure, thereby causing the lower bracket to collapse. Using the supporting plate 6 to support the upper bracket can disperse the pressure of the upper bracket on the lower bracket, so that the lower bracket will not collapse.

[0026] A through hole is provided in the middle of the support plate 6, and the support plate 6 is welded to the handle 7. The support plate 6 is connected to the outer inner support ring 2 through a support rod 9, and the support rod 9 and the support plate 6, and the support rod 9 and the outer inner support ring 2 are all welded.

[0027] When using a multi-station bracket provided by the utility model, the casting is first placed on the outer and inner support rings 2 and the outer support ring 1 of each layer. After the casting is placed, the handle 7 in the middle is lifted and the bracket is placed in a furnace. Then, the completed casting is placed on another bracket, and the bracket is placed on the bracket in the furnace so that the outer and inner support rings 2 are placed in the support grooves 8. When all the brackets are placed, the furnace is closed for quenching.

[0028] Therefore, the utility model adopts the above-mentioned multi-station bracket, which has a simple structure. By setting a supporting device, the number of castings quenched each time is increased, and the quality of castings completed by quenching in the same batch can be guaranteed to be the same. By setting a supporting device, the brackets can be stacked and used, and the support plate can disperse the pressure of the upper bracket on the lower bracket, so that the lower bracket will not collapse.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
