Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a pouring funnel tool for a stream inoculant. Background Art

[0002] In the process of cast iron production, inoculation treatment is a key step to improve the performance of castings. This treatment process mainly involves adding a small amount of specific substances during the solidification of molten iron to promote nucleation, inhibit growth, and ultimately achieve grain refinement. This specific substance is the inoculant.

[0003] The traditional method of pouring inoculant with flow is that the staff needs to weigh the appropriate amount of inoculant in advance. When pouring molten iron into the pouring cup of the casting box, the staff also needs to manually flush the inoculant into the molten iron, and the formed casting can be obtained after the molten iron solidifies.

[0004] However, this manual pouring method makes it difficult to control the pouring speed of the inoculant, and it is easy for the inoculant to be unevenly distributed in the molten iron, which in turn affects the quality of the casting. Utility Model Content

[0005] In view of the above problems, the utility model provides a pouring funnel tool for a stream inoculant.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is as follows:

[0008] Furthermore, a connecting plate is provided between the funnel and the guide groove, and the connecting plate is vertically slidably arranged on the mounting frame. The mounting frame is provided with a first limiting member for limiting the movement of the connecting plate. The first limiting member includes a limiting bolt. A vertical strip hole is opened on the mounting frame along the vertical direction, and a first threaded hole with a size adapted to the limiting bolt is opened on the connecting plate. The limiting bolt passes through the strip hole and is threadedly connected in the first threaded hole.

[0009] Furthermore, the cross-section of the guide groove is V-shaped, the small mouth of the funnel extends into the guide groove, and a gap is left between the small mouth of the funnel and the edges of the V-shaped inner wall of the guide groove for the passage of the inoculant. One end of the guide groove is rotatably set on the connecting plate to adjust the height of the gap, and a second limit member is provided on the connecting plate to limit the rotation of the guide groove.

[0010] Furthermore, the second limiting member includes a mounting tube, a sliding rod and a screw rod. One end of the mounting tube is rotatably set on the connecting plate, one end of the sliding rod is slidably passed through the mounting tube, and the other end of the sliding rod is rotatably set on the outer wall of the guide groove. A second threaded hole with a size matching that of the screw rod is opened on the outer wall of the mounting tube. The screw rod is threadedly connected in the second threaded hole and movably abuts against the sliding rod.

[0011] Furthermore, a pull ring is provided at one end of the pull rod away from the plugging head.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a pouring funnel tool for a stream inoculant, referring to Figure 1 , Figure 2 and Figure 3, including a mounting frame 1, on which a funnel 2 for containing an inoculant is mounted, the large opening of the funnel 2 faces upward, and the small opening faces downward. A plugging head 3 for opening / closing the small opening is placed in the funnel 2, and a pull rod 31 is welded on the plugging head 3, and one end of the pull rod 31 away from the plugging head 3 extends out of the large opening of the funnel 2. A guide groove 4 for guiding the inoculant is installed below the funnel 2 on the mounting frame 1.

[0020] In the embodiment of the present application, the staff installs the mounting frame 1 on the top of the casting box to be poured, and makes the discharge end of the guide groove 4 located above the pouring cup of the casting box, and then pours the weighed inoculant into the funnel 2. When pouring molten iron into the pouring cup of the casting box, the plugging head 3 can be lifted by lifting the pull rod 31 to open the small mouth of the funnel 2. Under the action of gravity, the inoculant is evenly flushed into the molten iron through the guide groove 4. When the molten iron is poured, the inoculant is also discharged synchronously, avoiding the situation of large deviation in pouring speed during manual pouring, making the inoculant more evenly distributed in the molten iron, which has the effect of improving the quality of castings.

[0021] The amount of molten iron required for the casting is fixed, and the amount of inoculant can be obtained by the staff through multiple tests to ensure that when the molten iron is poured, the weighed inoculant also flows out.

[0022] Furthermore, a connecting plate 5 is installed between the funnel 2 and the guide groove 4, and the connecting plate 5 is vertically slidably arranged on the mounting frame 1, and a first limiting member 6 for limiting the movement of the connecting plate 5 is installed on the mounting frame 1. The first limiting member 6 includes a limiting bolt 61, a vertical strip hole 11 is opened on the mounting frame 1 along the vertical direction, and a first threaded hole whose size matches the limiting bolt 61 is opened on the connecting plate 5, and the limiting bolt 61 passes through the strip hole 11 and is threadedly connected in the first threaded hole.

[0023] In the embodiment of the present application, a connecting rod is welded between the funnel 2 and the connecting plate 5. Different types of castings have different sizes, and the required casting box sizes are also different. For casting boxes of different sizes, the height of the pouring cup may also be different. By moving the connecting plate 5, the height of the funnel 2 and the guide groove 4 in the vertical direction can be adjusted so that the inoculant discharged from the guide groove 4 can be stably discharged into the pouring cup of the corresponding height. After adjusting the height of the funnel 2 and the guide groove 4, tighten the limit bolt 61 to fix the connecting plate 5.

[0024] Furthermore, the cross section of the guide groove 4 is V-shaped, the small mouth of the funnel 2 extends into the guide groove 4, and a gap is left between the small mouth of the funnel 2 and the corners of the V-shaped inner wall of the guide groove 4 for the inoculant to pass through. The specific gap height distance is 20 to 40 mm. One end of the guide groove 4 is rotatably set on the connecting plate 5 to adjust the height of the gap, and the connecting plate 5 is installed with a second limiter 7 for limiting the rotation of the guide groove 4.

[0025] In the embodiment of the present application, different types of inoculants are required for molten iron of different materials, and the volume sizes of different types of inoculants are also different. Therefore, when the corresponding inoculants are poured into the molten iron of different materials, the gap between the small mouth of the funnel 2 and the V-shaped inner wall corners of the guide groove 4 can be adjusted by rotating the guide groove 4 to ensure that the corresponding inoculant can be discharged from the funnel 2. In addition, since the small mouth of the funnel 2 extends into the guide groove 4, it can also prevent the inoculant from scattering out of the guide groove 4 when it is discharged from the funnel 2.

[0026] Reference Figure 4 The second stopper 7 includes a mounting tube 71, a slide bar 72 and a screw 73. One end of the mounting tube 71 is rotatably mounted on the connecting plate 5, one end of the slide bar 72 is slidably inserted into the mounting tube 71, and the other end of the slide bar 72 is rotatably mounted on the outer wall of the guide groove 4. A second threaded hole having a size matching that of the screw 73 is provided on the outer wall of the mounting tube 71. The screw 73 is threadedly connected in the second threaded hole and movably abuts against the slide bar 72.

[0027] In the embodiment of the present application, the gap height between the funnel 2 and the guide groove 4 can be adjusted by rotating the movable end of the guide groove 4. After the adjustment is completed, the screw 73 is rotated to abut the slide rod 72 in the mounting tube 71, so as to limit the movement of the slide rod 72 relative to the mounting tube 71, thereby limiting the rotation of the guide groove 4.

[0028] Furthermore, a pull ring 32 is welded to one end of the pull rod 31 away from the plugging head 3 .

[0029] In the embodiment of the present application, since the temperature of the molten iron is relatively high, the staff can use steel bars or other tools to hook the pull ring 32 and lift the plugging head 3 to discharge the inoculant in the funnel 2. After the inoculant is discharged, the pull ring 32 is lowered to allow the plugging head 3 to block the small opening of the funnel 2.

[0030] The implementation principle of the pouring funnel tooling of a flow inoculant in the embodiment of the present application is as follows: the staff installs the mounting frame 1 on the top of the casting box to be poured, and makes the discharge end of the guide groove 4 located above the pouring cup of the casting box, and then pours the weighed inoculant into the funnel 2. When pouring molten iron into the pouring cup of the casting box, lift the pull rod 31 to lift the plugging head 3 to open the small mouth of the funnel 2. Under the action of gravity, the inoculant is evenly flushed into the molten iron through the guide groove 4. When the molten iron is poured, the inoculant is also discharged synchronously, avoiding the situation of large pouring speed deviation during manual pouring, making the inoculant more evenly distributed in the molten iron, which has the effect of improving the quality of castings.
