DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0028] Example 1: See Figures 1 to 5 As shown, a forging scale removal process, the steps are:

[0029] ①Put the heated forging on the forging machine for forging;

[0030] ② During the forging process, the water outlet of the oxide scale removal device sprays water on the forging to cool it down and reduce dust;

[0031] ③ During the water spraying process, the scale removal device is swung at an angle so that water can be sprayed on various positions of the forging.

[0032] The scale removal device starts spraying water when the forging begins, and continues spraying water for 1 minute after the forging is completed.

[0033] In this way, during forging, the forging is in contact with the air, and oxide scale will be generated on its surface. If it is not cleaned in time, the oxide scale is easy to be forged into the inside of the forging, affecting the quality of the forging. At the same time, the staff needs to use a broom to clean it. When the staff cleans, due to the high temperature of the forging accessories, the cleaning is difficult and inconvenient, and it is easy to burn the user. Sometimes due to the high temperature, the broom will also burn. If a shovel is used for cleaning, the shovel is heavier than the meter, the labor intensity of the staff will be higher, and the shovel is heat-conductive, so that the staff has the hidden danger of scalding, and the cleaning speed is also slow. Therefore, in this embodiment, by using the water outlet of the oxide scale removal device to spray water, the oxide scale on the surface of the forging is directly cleaned by spraying water during the forging process, and the cleaning speed is fast and efficient, and the forging quality of the forging can also be guaranteed.

[0034] See also Figures 1 to 5 As shown, in order to achieve the above-mentioned purpose, the present invention adopts a forging scale removal device, including a frame 1, an annular tube 2 and a telescopic cylinder 3 arranged on the frame, the two ends of the annular tube are respectively rotatably installed on the frame via a rotating shaft 4, the annular tube is a hollow structure, an annular cavity 5 is arranged inside the annular tube, a plurality of groups of water outlet holes 6 are arranged at intervals on the left outer edge surface of the annular tube, and the water outlet holes are connected to the annular cavity; a water inlet 7 is respectively arranged on the top and bottom of the right side of the annular tube, and the water inlet is connected to the annular cavity, each group of the water inlets is connected to a joint 8, and each group of the joints is connected to a water pipe 9;

[0035] A connecting plate 10 is provided at the outer end of a group of the rotating shafts, the bottom of the connecting plate is vertically connected to the rotating shaft, the end of the telescopic cylinder is rotationally connected to the frame, and the output shaft of the telescopic cylinder is rotationally connected to the top of the connecting plate.

[0036] In this embodiment, in actual use, the frame is directly placed next to the forging equipment, and the water outlet of the annular tube is facing the forging. When the high-temperature forging is placed on the forging machine for forging, the water pipe supplies water to the annular tube. There are multiple groups of water outlets on the annular tube, and the water outlets spray water directly on the forging, so that the oxide scale produced on the surface of the forging can be cleaned up in time by using the water outlets. Among them, since the position of the forging will change during the forging process, through the setting of the telescopic cylinder, the extension and retraction of the output shaft of the telescopic cylinder will drive the annular tube to swing back and forth through the rotating shaft through the connecting plate and the rotating shaft, so that the direction of the water outlet spraying can be adjusted in real time, and the oxide scale at various positions on the surface of the forging can be cleaned up in time, and no manual cleaning is required, which effectively reduces the labor intensity of the operator, improves the cleaning efficiency, reduces safety hazards, and ensures the forging quality.

[0037] See also Figure 2 ,3 As shown in Figure 5, an annular baffle 11 is provided in the middle of the annular cavity, the outer edge surface of the annular baffle is connected to the outer edge surface of the inner wall of the annular cavity, and the inner edge surface of the annular baffle is arranged close to the inner edge surface of the inner wall of the annular cavity.

[0038] The water inlet is arranged on the right side of the annular baffle, and the water outlet is arranged on the left side of the annular baffle.

[0039] In this embodiment, through the setting of the annular baffle, the water entering the water inlet will bypass the inner side of the annular baffle, then flow to the left side of the annular baffle, and then spray out from the water outlet. In this way, the water flow out of each water outlet can be uniform, and the water flow velocity of the upper and lower water outlets will not be faster due to the water inlet being close to the top and bottom of the annular tube. In this way, the water flow velocity of each water outlet can be guaranteed to be uniform, thereby ensuring the stability and quality of cleaning.

[0040] See also Figure 2 , 4 As shown in FIG. 5 , a transverse tube 12 is provided in the middle portion of the inner side of the annular tube. The transverse tube is arranged parallel to the rotating shaft and is coaxial with the rotating shaft.

[0041] The two ends of the transverse tube are respectively connected to the two ends of the inner side of the annular tube; a transverse cavity 13 is provided in the middle of the annular tube, and the two ends of the transverse cavity are connected to the annular cavity.

[0042] A plurality of groups of middle water outlet holes 14 are arranged at intervals on the left side surface of the transverse tube, and the middle water outlet holes are communicated with the transverse cavity.

[0043] By setting the transverse pipe, on the basis of the water spraying from the annularly evenly distributed water outlet holes, a central water outlet hole can be set in the middle to spray water. This can ensure that the water spraying at each position can cover each position of the forging and ensure the cleaning quality of the oxide scale.

[0044] Among them, the bottom of the frame is provided with a plurality of supporting casters 15. The setting of the supporting casters can move the frame. When loading and unloading forgings, the annular tube can be removed by the supporting casters for easy loading and unloading. When it is needed, it can be moved to the side of the forging equipment. When it is not in use, it can be removed for easy storage.

[0045] Among them, two groups of limiting holes 16 are provided on the frame, and the limiting holes are arranged on the right side of the annular tube. The inner diameter of each group of limiting holes is larger than the outer diameter of the water pipe, and the middle part of each group of water pipes is inserted into one group of limiting holes.

[0046] Since the annular tube will also pull the water pipe to swing back and forth during the swinging process, the middle part of the water pipe can be guided and positioned by setting the limiting holes to prevent the water pipe from being cluttered and ensure the stability of the water spray.
