as shown in fig. 9 and 11, while the second rotating shaft 2275 rotates, the second rotating shaft 2275 further drives the third rotating shaft 2281 to rotate through the third belt 22753, the third rotating shaft 2281 drives the third hooking knife 2283 to rotate through the second rotating belt 2282 to scrape the rough edges on the outer surface of the molded part, then the rough edges are cleaned through the second cleaning plate 2284 staggered with the third hooking knife 2283, and the cleaned rough edges fall into the second accommodating frame 2285 to be collected, so that the molded part of the sealing ring is scraped in a multidirectional and synchronous manner by adopting the rotation of the molded part to perform transverse supply and the longitudinal scraping of the scraping part, and the scraping is more sufficient and has no dead angle;

as shown in fig. 10 and 12, in the present invention, a first accommodating frame 2276 and a second accommodating frame 2285 are respectively disposed below the second rotating shaft 2275 and the second cleaning plate 2284, and the length of the second hooking knife 22751 is sequentially shortened from two sides of the second rotating shaft 2275 to the middle of the second rotating shaft 2275, for the purpose, according to the fact that when the actual sealing ring forming piece is discharged, the burrs at the outer circular arc part of the circular forming piece close to the concave part are more, the second material hooking knife 22751 formally cleans burrs of an outer circular arc close to the concave part of the formed part, therefore, the length of the second hooking knives 22751 is sequentially shortened from the two sides of the second rotating shaft 2275 to the middle of the second rotating shaft 2275, so that the second hooking knives 22751 can be fully contacted with the outer arc, the burrs can be removed more fully, the removed burrs can be timely and nearby discharged into the first accommodating frame 2276 for recycling, so that more burrs after being processed by the second hooking knife 22751 are prevented from interfering the second scraping part 228 to process the outer circular surface with less burrs;

it should be added that when the formed part is driven by the positioning post 113 to rotate, the burrs at the corners of the concave part are difficult to completely extend due to the size of the equipment, and can be brought out by the corner cleaning piece 22711, and the burrs at the shorter part of the transition section between the second rotating shaft 2275 and the third rotating shaft 2281 are scraped by the transverse scraping plate 22761 and fall into the first accommodating frame 2276.

After the burr is removed, the cylinder in the guiding column 313 drives the driving block 316 to disengage from the push rod 220 and move upwards through the pressing member 315, as shown in fig. 7, at this time, the thrust spring 223 pushes the mounting bracket 221 to move, so that the mounting bracket 221 drives the clutch wheel 224 to disengage from the driving toothed disc 111 and return to the initial position.

Example two

As shown in fig. 1 and fig. 13, the same or corresponding components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and only the differences from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that:

as a refinement, the transfer unit 3 includes:

the hold-down assembly 31;

the molding assembly 32, the molding assembly 32 is arranged below the positioning unit 1;

the hold-down assembly 31 includes guide posts 313;

the upper end of the guide column 313 is connected with a lower pressing piece 315;

an upper cover plate 311 is arranged at the upper part of the transfer unit 3;

the upper part of the upper cover plate 311 is provided with a first cylinder 312 for driving the guide post 313 to move up and down;

the molding assembly 32 includes:

a mold 321;

the mold discharging rod 322, the mold discharging rod 322 is inserted in the mold 321 in a sliding manner;

the second air cylinder 323, the said second air cylinder 323 is connected to the lower end of the said mould 321;

a side stage 324, wherein the side stage 324 is connected to the side of the mold 321;

and a third air cylinder 325, wherein the third air cylinder 325 is used for transferring the molded part out and is connected to the side part of the main platform 110.

It should be noted that after the burr removing operation is completed, the third cylinder 325 drives the positioning unit 1 with the formed part to move out from the right above the forming assembly 32 along the side loading platform 324 to complete the discharging operation, the pressing assembly 31 descends to be attached to the forming assembly 32, the next forming operation is continued, after the forming operation is completed, the second cylinder 323 drives the mold 321 to sink, the formed part with burrs is pushed against the outer edge of the guide post 313 by the mold release rod 322 to perform the next deburring operation, so that the extrusion forming and deburring integrated forming function is realized, and the working efficiency is further improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
