Description

Technical Field

[0001] The utility model relates to the technical field of medium and thick plate casting automation, in particular to a device for positioning a No. 1 spraying machine of a medium and thick plate casting machine. Background Art

[0002] In the thin plate plant, the ingots from the thick plate casting machine are cut into ingots of required length by the No. 1 cutting machine. After cutting, the ingots need to be transported by rollers to the No. 1 spraying machine for spraying numbers. The conventional method of positioning the ingots is to set a laser positioning device at the No. 1 spraying machine. However, due to the large amount of water vapor and smoke at the No. 1 spraying machine, especially in cold winter weather, the water vapor greatly interferes with the laser positioning. In severe cases, the No. 1 spraying machine cannot work automatically. Utility Model Content

[0015] 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.

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0018] See also Figure 1 , a device for positioning the No. 1 spraying machine of a medium and thick plate casting machine, comprising:

[0019] Roller table, used to transport the ingot to No. 1 spraying machine;

[0020] The opposing grating is arranged on the roller and away from the No. 1 marking machine. When the ingot passes through the opposing grating, the speed of the roller and the transportation time of the ingot are recorded. When the ingot reaches the predetermined position, the transportation of the ingot is stopped and the No. 1 marking machine is used to complete the marking of the corresponding ingot.

[0021] Furthermore, the opposing grating includes: a transmitter and a receiver; the transmitter is arranged on one side of the roller conveyor, and the receiver is correspondingly arranged on the other side of the roller conveyor.

[0022] The utility model further illustrates the above process in conjunction with specific embodiments below:

[0023] like Figure 1 As shown in the figure, the process flow corresponding to the device positioned at the No. 1 spraying machine of the medium and thick plate casting machine is that after the billet is cut by the No. 1 fire cutter, the billet is transported to the No. 1 spraying machine through the roller in the No. 1 spraying machine area. The billet head stops at about the 10th roller position in the roller area of ​​the No. 1 spraying machine. After the billet stops, it is sprayed. After the spraying is completed, the billet is transported to the No. 2 and No. 3 fire cutting areas. It should be noted that Figure 1 In the figure, the triangular symbol indicates the installation position of the corresponding grating. The number 1 in the figure refers to the first virtual frame area, which is the No. 1 fire cutting area. The number 2 in the figure refers to the second virtual frame area, which is the No. 1 spray number area. The number 3 in the figure refers to the third virtual frame area, which is the No. 2 and No. 3 fire cutting areas.

[0024] like Figure 2 As shown, the positioning process corresponding to the device for positioning the ingot at the No. 1 spraying machine of the medium and thick plate casting machine is that after the ingot is cut by the No. 1 fire cutting, the ingot is transported to the No. 1 spraying machine through the roller. When the ingot head reaches the opposing grating, the ingot head blocks the opposing grating, and the opposing grating return signal is 1, and the calculation of the distance traveled by the ingot starts. The distance traveled by the ingot is calculated by multiplying the speed of the ingot roller by the travel time. When the distance traveled by the ingot is greater than the set value, the position signal of the ingot arriving at the No. 1 spraying machine is in place, and the positioning of the ingot at the No. 1 spraying machine is completed.

[0025] like Figure 3 As shown, the speed of the billet roller is calculated by selecting the speed value of the frequency converter feedback of rollers No. 6, 7, and 8 in the No. 1 spray machine area. First, select roller No. 6. If roller No. 6 is running, select roller No. 6. If roller No. 6 is not running, select roller No. 7. If roller No. 7 is not running, select roller No. 8. Because in actual production, sometimes 1-2 rollers will fail, such as reducer failure or motor damage, etc., and 1-2 roller failures will not affect production. By selecting 1 roller speed among these 3 rollers to calculate the travel distance, it can be ensured that even if 1-2 roller failures occur, the positioning of the billet will not be affected.

[0026] The utility model is used to design a device for positioning the No. 1 spray number machine of a medium and thick plate casting machine. The device is combined with a conventional positioning method, and a beam grating is installed in front of the No. 1 spray number machine. In addition, the speed is calculated through feedback from a roller table frequency converter. This can avoid the problem of interference from water vapor and inaccurate positioning signals when the beam grating is directly installed at the No. 1 spray number. Compared with the conventional positioning method, no equipment is added or other equipment is changed.

[0027] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
