Description

Technical Field

[0001] The utility model relates to the technical field of pouring machine equipment, in particular to a slag blocking device for a pouring machine. Background Art

[0002] The pouring machine is a device used to complete casting in the workshop. It can improve the success rate of castings, reduce the waste of molten iron and the occurrence of burns. Some existing small foundries use manual pouring. Usually, two people hold the two ends of two steel pipes respectively, and a steel furnace is set up in the middle. The steel furnace is filled with molten steel. The steel pipe and the steel furnace are combined to form a pouring machine. When pouring is required, two workers lift the steel pipe on one side, so that the positions of the steel pipes on both sides are one high and one low, thereby pouring the molten steel to complete the pouring. During the pouring process, in order to prevent the iron slag at the bottom of the steel furnace from flowing into the casting with the molten steel, a slag blocking device is usually used. The existing slag blocking device The slag blocking device is usually slag cotton. When the steel furnace is about to tip over, the third worker holds a piece of slag cotton and places it on the place where the steel furnace is about to tip over. Two workers tip over, and one worker presses the slag blocking cotton to keep the slag blocking cotton in contact with the horizontal surface of the molten steel to perform slag blocking operations. However, this method has certain defects. When pressing the slag blocking cotton, the worker needs to get close to the molten steel to ensure that the horizontal surface of the molten steel can be observed. However, getting close to the molten steel is dangerous. Sputtering may occur when the molten steel tips over. If it accidentally splashes onto the worker, it will be troublesome. For this reason, we propose a slag blocking device for a pouring machine. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1-7The utility model provides a technical solution: a slag blocking device for a pouring machine, comprising a steel furnace 1, a steel pipe 2 is arranged on both sides of the steel furnace 1, and slag blocking cotton 3 is arranged outside the steel furnace 1, and also includes:

[0030] Column 1 4, column 1 4 is fixedly arranged on the steel pipe 2, and the other end of column 1 4 is connected to the slag-blocking cotton 3;

[0031] A pressing rod 5, the pressing rod 5 is arranged on the steel pipe 2, and one end of the pressing rod 5 is in contact with the slag-blocking cotton 3;

[0032] A deflection rod 6, which is rotatably disposed on the steel pipe 2 and is located at one end of the steel pipe 2, away from the steel furnace 1;

[0033] The pressing assembly 7 is arranged on the steel pipe 2, and the pressing rod 5 and the deflection rod 6 are respectively connected to the pressing assembly 7. The steel pipe 2 on one side is rotated to drive the column 1 4 to deflect, so that the slag-blocking cotton 3 is located at the open end of the steel furnace 1. The deflection rod 6 is pressed, and the pressing rod 5 is driven by the pressing assembly 7 to deflect and tilt while pressing the slag-blocking cotton 3, so as to make the slag-blocking cotton 3 always fit the horizontal surface of the molten steel in the steel furnace 1. Specifically, the pressing assembly 7 includes a rod 1 71 rotatably connected to the other end of the deflection rod 6, a rod 2 72 is rotatably arranged on the rod 1 71, and the rod 2 72 is located in the steel pipe 2 and slides. A stopper 73 is fixedly arranged on the other end of the rod 2 72, and a rod 3 74 is rotatably arranged in the stopper 73. The rod 3 74 is rotatably connected to the pressing rod 5, and one end of the pressing rod 5 is designed in a hammer shape and contacts with the slag-blocking cotton 3.

[0034] When it is necessary to move the steel furnace 1, a steel pipe 2 is slid into it from both sides of the steel furnace 1, and then two people hold the steel pipe 2 from both ends respectively, and the steel furnace 1 can be moved and transported. At this time, the pressing rod 5 and the slag blocking cotton 3 are both located on both sides of the steel furnace 1, not on the open end of the steel furnace 1, so that it is convenient to insert the steel pipe 2 without affecting the insertion and disengagement of the steel pipe 2. When it is desired to perform pouring operations, the steel pipe 2 on one side of the slag blocking cotton 3 is first rotated. After the slag blocking cotton 3 is deflected, it is located at the open end of the steel furnace 1 and fits on the horizontal surface of the molten steel. Then, the steel pipe 2 on one side of the pressing rod 5 is rotated until the pressing rod 5 is rotated to the top of the slag blocking cotton 3 and contacts with the slag blocking cotton 3, and then pouring is performed. As the molten steel pours less and less, the horizontal plane will also tilt and change. At this time, the deflection rod 6 is pressed to drive the rod 1 71 to deflect and tilt, thereby driving the rod 2 72 to slide in the steel pipe 2, and then driving the stopper 73 to slide. The function of the stopper 73 is to prevent the rod 2 72 from deflecting backwards. With the stopper 73 After that, rod 2 72 can only slide in the direction of pressing rod 5. Because block 1 9 cooperates with steel pipe 2, after rod 2 72 slides toward block 1 9, it drives pressing rod 5 to deflect and tilt downward. One end of pressing rod 5 is hammer-shaped, which has the advantage of increasing the contact area with slag blocking cotton 3, so that slag blocking cotton 3 can be kept in close contact with the horizontal plane of molten steel as much as possible, thereby enhancing the slag blocking effect and not affecting the pouring of molten steel. When pouring, the steel pipe 2 can be rotated inward at the same time, so that the slag blocking cotton 3 can be closer to the molten steel, so that the pressing rod 5 can be closer to the slag blocking cotton 3, which can assist in pressing slag blocking, enhance the slag blocking effect, and reduce the possibility of molten steel splashing, reduce the need for manpower, and only need two people to complete the pouring and slag blocking operations, without the need for a third person to block slag. At the same time, slag blocking does not need to be close to molten steel, only need to stand on both sides of the steel furnace 1 for observation, and control the degree to which the pressing rod 5 presses the slag blocking cotton 3 by changing the force of pressing the deflection rod 6, which is convenient and quick.

[0035] A shaft 8 is rotatably provided on the column 4, a rod 4 81 is fixedly connected to the shaft 8, a plurality of shafts 82 are rotatably provided on the rod 4 81, both ends of the shaft 82 are rotatably connected to the rod 4 81 and the slag-blocking cotton 3 respectively, and one of the shafts 82 is designed with a telescopic rod, and there is damping in the telescopic rod to enable the slag-blocking cotton 3 to deflect and tilt. Through the shaft 82 and the telescopic rod, the slag-blocking cotton 3 can be deflected and tilted as much as possible, thereby ensuring that it remains in contact with the horizontal plane of the molten steel.

[0036] A block 9 is sleeved on the pressing rod 5, and the block 9 is in a circular ring shape. The block 9 is rotatably connected to the steel pipe 2 through a rod to limit the pressing rod 5. The advantage is that it limits the pressing rod 5 without affecting its sliding, so that the pressing rod 5 can deflect and tilt and press the slag-blocking cotton 3.

[0037] A spring 10 is provided on the deflection rod 6, and the two ends of the spring 10 are fixedly connected to the deflection rod 6 and the steel pipe 2 respectively, so as to drive the deflection rod 6 to automatically return to its position through the elastic force of the spring 10. The advantage is that it can be automatically reset, and by cooperating with the deflection rod 6 and the spring 10, the force of pressing the deflection rod 6 can be changed, and the degree of pressing can be changed, which is more convenient.

[0038] The pressing rod 5 and the column 4 are respectively located on both sides of the steel furnace 1 to reduce the obstruction of the steel furnace 1 from tipping over. The pressing rod 5 and the column 4 are respectively located on the diagonal lines of the steel furnace 1 to reduce the possibility of obstructing the view of the molten steel in the steel furnace 1, while facilitating the steel pipe 2 to slide in and out of the steel furnace 1 for disassembly and assembly.

[0039] Example 2

[0040] See also Figure 1-9 The utility model provides a technical solution: a slag blocking device for a casting machine, and embodiment 2 is optimized on the basis of embodiment 1.

[0041] A spring 10 is also provided inside the telescopic rod of the second shaft 82, and the two ends of the spring 10 are fixedly connected to the two ends of the telescopic rod respectively. A torsion spring 11 is provided on the first shaft 8, and the two ends of the torsion spring 11 are fixedly connected to the first shaft 8 and the column 1 4 respectively. The spring 10 can make the telescopic rod of the second shaft 82 automatically return to its position, and the torsion spring 11 can make the first shaft 8 drive the rod 4 81 to return to its position, and then drive the slag stopper cotton 3 to return to its position. The advantage is that the possibility of the slag stopper cotton 3 sticking to the steel furnace 1 when the steel furnace 1 is separated from the steel pipe 2 is reduced, which is convenient for separation and can be automatically separated.
