[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-2 This patent provides a technical solution: a curling processing device for the mouth of a metal barrel, comprising a mold body 1 and a metal barrel 2, an annular cavity 3 is opened on the upper wall of the mold body 1, the mouth of the metal barrel 2 is inserted into the annular cavity 3, guide columns 4 are installed at the four corners of the upper wall of the mold body 1, and an upper pressing plate 5 is slidably installed on the outer side of the guide column 4;

[0022] The upper pressing plate 5 is connected to an external hydraulic press, and the hydraulic press drives the upper pressing plate 5 to move downward, so that the metal barrel 2 is pressed downward, and the barrel mouth of the metal barrel 2 is curled through the annular cavity 3 on the mold body 1;

[0023] The function of the guide column 4 in this article is to guide the upper pressing plate 5 to prevent the upper pressing plate 5 from deflecting during the downward movement;

[0024] Through holes 6 are provided at the four corners of the upper wall of the upper pressing plate 5, and the guide column 4 is inserted into the through holes 6. The side wall of the upper pressing plate 5 is installed with an electric slide rail 7, and the electric slide rail 7 is electrically connected to an external power supply. A mounting frame 8 is installed on the side wall of the slider of the electric slide rail 7, and a brush 9 is installed on the upper wall of the mounting frame 8, and the brush 9 is in contact with the lower wall of the upper pressing plate 5;

[0025] By controlling the movement of the slider on the electric slide rail 7, the brush 9 is driven to clean the lower wall of the upper pressing plate 5, and impurities such as iron filings attached to the surface are swept off and fall into the collection box 11;

[0026] One end of a connecting rod 10 is mounted on the side wall of the mounting frame 8, and a collecting box 11 is mounted on the other end of the connecting rod 10. The collecting box 11 is located below the bristles 9;

[0027] The collecting box 11 can collect impurities to prevent the impurities from falling into the annular cavity 3 on the mold body 1 and affecting the curling effect of the metal barrel 2 .

[0028] Specifically, the collection box 11 includes a box body 111, a magnetic pad 112 and an inclined plate 113. The inclined plates 113 are installed on both sides of the box body 111, and the magnetic pad 112 is installed inside the box body 111.

[0029] The magnetic pad 112 can absorb the iron filings to prevent them from falling out of the collection box 11;

[0030] The magnetic pad 112 proposed in this article belongs to the prior art and is usually used in wire cutting processing.

[0031] Specifically, a sleeve 12 is installed in the through hole 6, and the sleeve 12 is sleeved on the outer side of the guide column 4. The outer side of the sleeve 12 is provided with an external thread, and an adjusting nut 13 is installed on the outer side of the sleeve 12 by rotating the thread. The adjusting nut 13 is located below the upper pressure plate 5;

[0032] Because a tubular level 14 is set above the upper pressure plate 5, according to observing the tubular level 14, if the upper pressure plate 5 is in a non-horizontal state, it is necessary to adjust the upper pressure plate 5 to a level by rotating the corresponding adjusting nut 13 to avoid affecting the curling effect of the metal barrel 2.

[0033] Specifically, a tubular level 14 is installed on the upper wall of the upper pressing plate 5 .

[0034] Specifically, a fixing ring 15 is installed at the upper end of the sleeve 12, and the fixing ring 15 is filled with lubricating oil. A sponge sleeve 16 is sleeved at the lower end of the sleeve 12, and the sponge sleeve 16 is in contact with the side wall of the guide column 4;

[0035] The lubricating oil can lubricate the guide column 4, making the upper pressing plate 5 smoother during the sliding process and avoiding the jamming phenomenon;

[0036] The sponge cover 16 can absorb the excess lubricating oil to avoid affecting the cleanliness of the device.

[0037] Specifically, the side wall of the mold body 1 is provided with an air flow channel 17, the air flow channel 17 is connected to the annular cavity 3, one end of an air pipe 18 is inserted into the air flow channel 17, and the other end of the air pipe 18 is connected to an external air pump;

[0038] When the annular cavity 3 needs to be cleaned, it is only necessary to start the external air pump, and the air flow enters the annular cavity 3 through the air pipe 18 to blow out the impurities inside the annular cavity 3, which is very convenient.

[0039] Working principle: Place the metal barrel 2 in the annular cavity 3 above the mold body 1, and then the staff rotates the adjustment nut 13 according to the position of the bubble in the tubular level 14 to adjust the upper pressing plate 5 to the horizontal level, and then control the external hydraulic press to press down, drive the upper pressing plate 5 to move downward, so that it presses the metal barrel 2 downward, and the barrel mouth of the metal barrel 2 is curled through the annular cavity 3 on the mold body 1;

[0040] After each downward pressing is completed and the upper pressing plate 5 is lifted, the slider on the electric slide rail 7 is controlled to move, so that it drives the brush bristles 9 to clean the lower wall of the upper pressing plate 5, sweeping off impurities such as iron filings attached to the surface and making them fall into the collection box 11, so as to avoid loose contact between the metal barrel 2 and the upper pressing plate 5, which will affect the curling effect of the metal barrel 2.
