Description

TECHNICAL FIELD

[0001] The utility model belongs to foundry technology field, concretely relates to a foundry goods cooling frock with limiting function. BACKGROUND

[0002] In the production of castings, the castings always need to be handled by cold working before they can be put into normal use. The cooling treatment of castings is simply to let the temperature of the castings drop from a high temperature state to the ambient temperature to reach equilibrium. Natural cooling is a very common cooling method for castings, but it takes a long time. Air cooling is to reduce the temperature of the castings by blowing or compressed air from a blower. Although the blower or compressed air can accelerate the cooling speed of the castings, it is easy to cause uneven cooling, and the castings are prone to displacement during the cooling process, affecting the stability and quality of the castings.

[0003] To solve the above technical problems, the utility model provides a foundry goods cooling frock with limiting function, which can accelerate the cooling of the castings.

[0004] To achieve the purpose of the utility model, the utility model adopts the technical scheme that:

[0005] A foundry goods cooling frock with limiting function, comprising an annular pipeline and a plurality of parallel cooling pipelines, the annular pipeline is provided with an air inlet, the air inlet end of the cooling pipeline is fixedly connected to the annular pipeline and is arranged around the annular pipeline, and the inner side of the cooling pipeline is equidistantly arranged with a plurality of air blowing holes and the end is a closed plane.

[0006] The upper part of the cooling pipeline is provided with an air valve switch.

[0007] The outer diameter of one end of the cooling pipeline connected to the annular pipeline is smaller than that of the other end.

[0008] The upper part of the cooling pipeline is not provided with air blowing holes.

[0009] The inner diameter of one end of the cooling pipeline connected to the annular pipeline is smaller than that of the annular pipeline.

[0010] The diameter of the air blowing hole is 2-3mm, and the spacing is 50mm, which is the best uniform air blowing effect.

[0012] 1. The cooling frock of the utility model covers the castings in the cooling pipeline, the cooling pipeline is stably arranged on the ground, the castings cannot be displaced, and the castings are uniformly blown from the air blowing holes of the cooling pipeline, accelerating the cooling of the castings.

[0013] 2、cooling pipe and ring pipe connected to one end of the smaller outer diameter than the end, the cooling pipe bottom surface and the ground contact area is large, better support, more conducive to the stability of standing.

[0014] 3、in the upper part of the cooling pipe gas valve switch, you can manually adjust the wind speed, or choose to close individual cooling pipe. BRIEF DESCRIPTION OF DRAWINGS

[0018] In order to more clearly, detailedly explain the purpose of the technical scheme of the present application, the following through the related examples of the present application are further described. The following examples are only to illustrate the implementation method of the present application, and do not limit the protection scope of the present application.

[0019] Example 1

[0020] As Figure 1 And Figure 2 As shown in a kind of castings cooling tool with limiting function, including ring pipe 1 and multiple parallel cooling pipe 2, the ring pipe 1 is provided with air inlet 11, the air inlet end of the cooling pipe 2 is fixedly connected ring pipe 1 and is arranged around it, the inside of the cooling pipe 2 is equidistantly arranged with multiple blowhole 21 and the end is closed plane.

[0021] When using, the castings are placed in the cooling tool, so that the castings are surrounded by cooling pipe 2, the bottom of cooling pipe 2 is plane, can be stably on the ground, so that the castings cannot be displaced. The cold air is introduced into the air inlet 11 of the ring pipe 1, and the castings are uniformly blown by the blowhole 21 of the cooling pipe 2, so as to accelerate the cooling of the castings.

[0022] The size of the ring pipe 1 and the cooling pipe 2 of the present application is customized according to the size of the actual castings.

[0023] Example 2

[0024] This embodiment is based on example 1:

[0025] The upper part of the cooling pipe 2 is provided with an air valve switch 3. The air speed can be manually adjusted as required, or the individual cooling pipes can be selected to be closed.

[0026] The air blowing hole has a diameter of 2mm and a spacing of 50mm.

[0027] Example 3

[0028] This embodiment is based on example 1:

[0029] The cooling pipe 2 is connected to the annular pipe 1 at one end with a smaller outer diameter than the other end, and the bottom surface of the cooling pipe 2 has a large contact area with the ground, better support, and better stability for standing.
