Description

Technical Field

[0001] This utility model relates to the field of sand core processing, specifically a sand core coating removal brush. Background Technology

[0002] Sand cores play a crucial role in forming the internal cavity and external shape of castings. To improve the performance of sand cores, such as heat resistance, chemical stability, and resistance to molten metal erosion, a coating is usually applied to the surface of the sand core. However, during the coating process, issues such as coating accumulation, sagging, and uneven thickness may occur. Due to the needs of subsequent processes, such as the sand core needing to be coated with different types of coatings again, or the coating on the surface of the sand core affecting the precision and quality of the casting, it is necessary to remove the coating from the surface of the sand core. This is usually done by using an electric brush to remove the accumulated coating from the surface of the sand core.

[0003] Some conventional brushes experience wear during the process of removing accumulated paint. This increases the gap between the brush and the core, resulting in poorer contact between the brush and the core surface, which affects the paint removal effect. Furthermore, the worn brush may bounce on the core surface, failing to fully utilize friction and thus reducing the efficiency of paint removal. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the brush will wear out during the process of removing paint accumulation, and the gap between the brush and the sand core will increase, resulting in poor contact between the brush and the sand core surface. This utility model proposes a sand core brush for removing paint accumulation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sand core decoction brush, including a brush body, a line connected to the brush body, a terminal fixedly connected to one end of the line, a housing slidably connected to the outside of the terminal, and an abutment mechanism provided inside the housing;

[0006] The abutment mechanism includes a spring and a movable ring. The spring is sleeved on the outside of the circuit, and a fixing block is fixedly connected to the side of the movable ring. An installation groove is provided on the inner wall of the outer shell, and a limit rod is fixedly connected in the installation groove.

[0007] Preferably, one end of the spring is fixedly connected to the movable ring, and the other end of the spring is fixedly connected to one end of the inner surface of the outer casing.

[0008] Preferably, the fixing block is slidably connected to the outside of the limiting rod.

[0009] Preferably, a connecting rod is fixedly connected to the side of the movable ring, and a screw hole is provided on the side of the connecting rod.

[0010] Preferably, one end of the brush body is fixedly connected to a mounting base, one end of the mounting base is slidably connected to a connecting rod, and one end of the mounting base is respectively provided with a groove and a through hole.

[0011] Preferably, the mounting base is movably connected with a bolt, the bolt is threaded to a threaded hole, and one end of the bolt has a groove.

[0012] Preferably, the inner diameter of the moving ring is larger than the diameter of the circuit, and the surface of the spring has an insulating coating.

[0013] The advantages of this utility model are:

[0014] This invention features a shell on one side of the brush body, with a spring and other components connecting the shell to the brush body. The spring is a constant-pressure spring, which allows the brush body to move under the elastic action of the spring when wear occurs during the decoction process. This enables the brush body to automatically follow the sand core, preventing poor contact between the brush body and the sand core. The constant-pressure spring provides continuous and uniform pressure, ensuring a stable decoction effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a sand core decoction brush for removing accumulated current. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A sand core coating removal brush includes a brush body 1, a line 2 connected to the brush body 1, a terminal 3 fixedly connected to one end of the line 2, a housing 4 slidably connected to the outside of the terminal 3, and an abutment mechanism 5 provided inside the housing 4.

[0026] The contact mechanism 5 includes a spring 51 and a moving ring 52. The spring 51 is sleeved on the outside of the line 2. A fixing block 53 is fixedly connected to the side of the moving ring 52. An installation groove 54 is opened on the inner wall of the outer shell 4. A limit rod 55 is fixedly connected in the installation groove 54. When the brush body 1 removes the paint accumulation on the surface of the sand core, current is provided through the external power supply connection of the terminal 3. The current then passes through the brush body 1 and connects to the sand core. A certain amount of heat is generated at the contact point between the brush body 1 and the sand core. This heat may change the physical properties of the paint accumulation, such as making it soft, melting, or reducing its adhesion to the surface of the sand core, thus making it easier to be removed by the brush body 1. When the brush body 1 is worn, the spring 51 can drive the moving ring 52 to move under the elastic action of the spring 51. This causes the moving ring 52 to drive the brush body 1 connected to the connecting rod 6 to move, so that the brush body 1 can fit tightly against the surface of the sand core. When the brush body 1 moves on the surface of the sand core, it can give full play to the friction effect and effectively remove the paint accumulation.

[0027] Reference Figure 3 and Figure 4One end of the spring 51 is fixedly connected to the moving ring 52, and the other end of the spring 51 is fixedly connected to one end of the inner side of the outer casing 4. The moving ring 52 can be moved by the elastic action of the spring 51, and the brush body 1 can be moved by the movement of the moving ring 52.

[0028] Reference Figure 1 and Figure 4 The fixing block 53 is slidably connected to the outside of the limiting rod 55. By sliding the fixing block 53 on the outside of the limiting rod 55, the limiting rod 55 can guide and limit the fixing block 53, which indirectly makes the movement of the brush body 1 more stable and less prone to deviation.

[0029] Reference Figure 1 , Figure 5 and Figure 6 A connecting rod 6 is fixedly connected to the side of the moving ring 52. A screw hole 7 is opened on the side of the connecting rod 6. A mounting base 8 is fixedly connected to one end of the brush body 1. The connecting rod 6 is slidably connected to one end of the mounting base 8. A groove 9 and a through hole 12 are opened on one end of the mounting base 8. A bolt 10 is movably connected inside the mounting base 8. The bolt 10 is threaded to the screw hole 7. A groove 11 is opened on one end of the bolt 10. When the brush body 1 needs to be replaced after long-term use, the bolt 10 can be moved out of the screw hole 7 on the side of the connecting rod 6 by rotating the groove 11 on the bolt 10. At this time, the connection between the connecting rod 6 and the brush body 1 is released, the line 2 is cut off, and the brush body 1 can be disassembled and then the brush body 1 can be replaced. The inner diameter of the through hole 12 is larger than the diameter of the line 2, which facilitates the spot welding connection between the brush body 1 and the line 2.

[0030] Reference Figure 2 and Figure 3 The inner diameter of the moving ring 52 is larger than the diameter of the line 2. The surface of the spring 51 has an insulating coating. By designing the inner diameter of the moving ring 52 to be larger than the diameter of the line 2, the problem of the line 2 being damaged or the brush body 1 being unable to move normally is avoided when the moving ring 52 is stuck in the outer casing 4 during movement. In addition, the insulating coating can effectively prevent current from passing through the spring 51, ensuring electrical isolation between the brush system and other live parts, and preventing personnel injury.

[0031] Working principle: Current is supplied through an external power supply connected to terminal 3. This current then flows through brush body 1 and connects to the sand core. Heat is generated at the contact point between brush body 1 and the sand core. This heat may alter the physical properties of the accumulated paint, such as softening, melting, or reducing its adhesion to the sand core surface, making it easier for brush body 1 to remove. When brush body 1 wears down, the elasticity of spring 51 causes spring 51 to move the moving ring 52, which in turn moves the brush body 1 connected to the connecting rod 6, thus allowing brush body 1 to move. The brush body 1 fits tightly against the surface of the sand core. When the brush body 1 moves on the surface of the sand core, it can fully exert the friction effect to effectively remove paint accumulation. When the brush body 1 needs to be replaced after long-term use, the groove 11 on the bolt 10 can be rotated to remove the bolt 10 from the screw hole 7 on the side of the connecting rod 6. At this time, the connection between the connecting rod 6 and the brush body 1 can be released, and the line 2 can be cut to remove the brush body 1. Then the brush body 1 can be replaced. The inner diameter of the through hole 12 is larger than the diameter of the line 2, which facilitates the spot welding connection between the brush body 1 and the line 2.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
