Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal roll casting production, in particular to a device for vertically aligning a pouring cup. Background Technique

[0002] A centrifugal roll is a new type of rolling equipment spare part. In the casting production process of the centrifugal roll, molten metal is poured into the roll cavity through a pouring system in a high-speed rotating mold. The centrifugal force makes the molten metal quickly and evenly fill the entire cavity. Then, the cooling system makes the metal in the roll quickly solidify and form. After closing the mold and filling the core for casting, through heat treatment and precision machining, high-quality rolls can be made.

[0003] In the prior art, when carrying out centrifugal roll casting production, first, the molten metal of the alloy layer is poured into the centrifuge roll mold. Through the high-speed rotation of the centrifuge, the alloy layer forms a hollow sleeve in the roll mold. Just after the alloy layer solidifies, the machine is quickly stopped and the mold is closed. Then, the pouring cup is placed on the pouring port of the mold box, and the core-filling molten iron is injected into the core of the roll mold through the pouring cup. However, in the process of core-filling casting, due to the pouring cup not being placed horizontally, the core-filling molten iron often flushes the centrifuged outer alloy layer, causing the alloy layer to be "offset", resulting in an insufficient thickness of the alloy layer. The operator often needs to stand on the upper part of the riser box and visually observe and position, which is not very convenient and prone to errors. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for vertically aligning a pouring cup, which solves the problem that the core-filling molten iron flushes the centrifuged outer alloy layer due to the pouring cup not being placed horizontally, resulting in the alloy layer being "offset" and thus an insufficient thickness of the alloy layer, and there is no need for the operator to stand on the upper part of the riser box for visual observation and positioning.

[0005] To solve the above technical problems, a device for vertically aligning a pouring cup of the utility model includes a pouring cup. The pouring cup is a funnel with a larger top diameter and a smaller bottom diameter. The top surface of the pouring cup is the feeding port, and the bottom surface of the pouring cup is the discharging port. The discharging port of the pouring cup is connected to the pouring port at the top of the riser box. A cross bar is fixedly connected to the top surface of the pouring cup. The center of the bottom surface of the cross bar is fixedly connected with a laser emitter. The laser emitter is coaxial with the pouring cup, and the laser of the laser emitter vertically shoots into the clay sand mold at the bottom of the riser box.

[0006] Further, an observation hole is provided in the upper part of the side wall of the pouring cup. The observation hole is a rectangular hole; the observation hole horizontally penetrates through the pouring cup.

[0007] Further, a reflective sheet is fixedly connected to the bottom surface of the cross bar. The reflective sheet is arranged on the side of the laser emitter. The included angle between the reflective sheet and the cross bar is 45 degrees, and the reflective sheet is within the horizontal range of the observation hole.

[0008] Furthermore, the distance between the reflective sheet and the laser emitter is 1 cm - 3 cm.

[0009] Furthermore, a sub-port positioning groove is provided at the discharge port of the sprue cup, and a padding block is connected in the sub-port positioning groove.

[0010] The beneficial effects of the present utility model are as follows: The laser emitter of the present utility model emits a light beam downward. By aligning the light beam with the center mark on the inner bottom surface of the clay sand mold, the effect of light beam positioning is generated, realizing the function of vertically aligning the sprue cup body at the casting port of the riser box, reducing the error caused by manual visual positioning in the prior art; The operator stands beside the mold and can directly observe whether the light beam in the mold is accurately positioned by horizontally visually observing the reflective sheet through the observation port, without the need for the operator to climb and observe; The crossbar can be used as a handle or a support point, improving the convenience of use.

[0015] As Figures 1 - 3 shown, a device for vertically aligning a sprue cup of the present utility model includes a sprue cup 1. The sprue cup 1 is a funnel with a larger top diameter and a smaller bottom diameter. The top surface of the sprue cup 1 is the feeding port, the bottom surface of the sprue cup 1 is the discharging port, and the discharging port of the sprue cup 1 is connected to the casting port 5 at the top of the riser box 6. A crossbar 2 is fixedly connected to the top surface of the sprue cup 1. A laser emitter 3 is fixedly connected to the center of the bottom surface of the crossbar 2. The laser emitter 3 is coaxial with the sprue cup 1, and the laser of the laser emitter 3 vertically penetrates into the clay sand mold 9 at the bottom of the riser box 6; An observation hole 101 is provided in the upper part of the side wall of the sprue cup 1. The observation hole 101 is a rectangular hole; The observation hole 101 horizontally penetrates through the sprue cup 1; A reflective sheet 4 is fixedly connected to the bottom surface of the crossbar 2. The reflective sheet 4 is arranged on the side of the laser emitter 3. The included angle between the reflective sheet 4 and the crossbar 2 is 45 degrees, and the reflective sheet 4 is within the horizontal range of the observation hole 101.

[0016] The mold 7 is connected inside the riser box 6. The top and bottom of the riser box 6 prevent the clay sand mold 9. Molten metal is poured into the centrifuge. Through the high-speed rotation of the centrifuge, an alloy layer 8 forms a hollow sleeve inside the mold 7. The laser emitter 3 emits a beam vertically downward. The beam irradiates the inner bottom surface of the clay sand mold 8, producing an effect of beam positioning, and realizing the function of vertically aligning the gate cup body 2 at the casting port of the riser box 3. At the same time, the operator stands beside the mold and can directly observe whether the beam in the mold is ready for positioning by horizontally observing the reflector 4 through the observation hole 101.

[0017] Regarding the structural stability of the cross bar 2, while supporting the laser emitter 3 and the reflector 4, the cross bar 2 can be used as a handle or a support point. The operator can easily hold or grasp the cross bar 9, providing better holding stability.

[0018] The discharge port of the gate cup 1 is provided with a sub-mouth positioning groove, and a padding iron is connected inside the sub-mouth positioning groove. To facilitate placing the padding iron at the bottom of the gate cup 1 and prevent the padding iron from sliding and shifting, a sub-mouth positioning groove is provided at the bottom of the gate cup 1, and the padding iron can be embedded in this sub-mouth positioning groove.

[0019] The distance between the reflector 4 and the laser emitter 3 is 1 cm - 3 cm.

[0020] When the present utility model is in use, first place the gate cup 1 on the casting port 5, turn on the laser emitter 3, and the laser emitter 3 emits a beam into the mold 7. The beam irradiates the inner bottom surface of the clay sand mold 9. At this time, the operator can stand beside the mold and horizontally observe the reflector 4 through the observation hole 10, and observe whether the beam irradiates the center mark on the inner bottom surface of the clay sand mold 9 through the reflector 4. If it does not irradiate the center mark, at this time, a padding iron can be added to the bottom of the gate cup body 2 until the beam irradiates the center mark on the inner bottom surface of the clay sand mold 9. Then, through an external positioning device, the device of the present utility model is stably positioned to ensure that it does not shift or shake, and then the next casting work is carried out.
