The application method, the principle and the advantages of the scheme are as follows: hanging the ring on a horizontal column of the existing rolling machine, adjusting a rolling roller of the existing rolling machine to press the ring, and then carrying out finish machining on the ring. After the processing is finished, the rolling roller is adjusted to be separated from the annular object, then the annular object is pushed out from the horizontal column by using two symmetrically arranged pushing-out units, the automatic blanking of the annular object is realized, and then the annular object falls into the material receiving unit below the horizontal column. The two extrapolation units are symmetrically distributed to ensure that the two extrapolation units can symmetrically apply force to the ring-shaped object, and further ensure that the ring-shaped object is successfully dropped from the horizontal column. Also, both of the pushing-out units are adapted to contact the upper portion of the ring, so that the ring can be pushed more efficiently (than if the ring is pushed at the lower portion of the ring) to be successfully removed from the horizontal column. This scheme can carry out automatic discharge to the cyclic annular thing that has processed, reduces operating personnel's intensity of labour, and then improves the change efficiency of cyclic annular work piece.

Preferably, as a refinement, the extrapolation unit includes a rotation piece; a shaft lever is arranged in the middle of the rotating piece, and the rotating piece rotates by taking the shaft lever as a rotating shaft; one end of the rotating sheet is used for contacting with the annular object, and the other end of the rotating sheet is hinged with a piston rod of the second air cylinder. The second cylinder controls the rotation of the rotating sheet, and the annular object is pushed out from the horizontal column through the movement of the rotating sheet, so that the automatic discharging of the processed annular object is realized.

Preferably, as an improvement, the receiving unit includes a first rail disposed obliquely. The processed ring-shaped object can be conveyed to a designated position through the first rail, so that the labor force of workers is saved.

Preferably, as an improvement, it also includes a first limit unit; the first limiting unit comprises first air cylinders and limiting heads, wherein the first air cylinders are positioned on the left side and the right side of the ring, and the first air cylinders are used for driving the limiting heads to move horizontally; the limiting head is internally provided with a limiting groove for accommodating the ring-shaped object. The above structure can increase the precision of processing the ring. When the rolling roller drives the annular object to rotate, the annular object can deviate left and right (or deviate front and back), so that the machining accuracy is influenced to a certain extent, and the limiting groove is used for preventing the annular object from deviating left and right or front and back excessively.

Preferably, as an improvement, a rotating bottom plate is rotatably connected to the bottom plate of the first rail. The rotating bottom plate is used for receiving the ring-shaped object falling from the horizontal column, and the ring-shaped object is prevented from directly falling onto the first track, so that the ring-shaped object is prevented from being damaged due to too large impact.

Preferably, as an improvement, the receiving unit further comprises a collecting box. The processed rings can slide into a collecting box through a sliding rail, and when the rings are accumulated to a certain amount, the rings are uniformly treated or transported.

As shown in FIG. 1, the automatic discharging device of the ring rolling machine comprises an outward pushing unit and a material receiving unit, wherein the outward pushing unit and the material receiving unit are both arranged on a vertical mounting plate 19.

The side of the rotating sheet B part 7 is integrally formed with two shaft levers 15, the number of the shaft levers 15 is two and the two shaft levers 15 are coaxially arranged, and the two shaft levers 15 are positioned at two sides of the rotating sheet B part 7. As shown in fig. 3, vertical support plates 13 are fixed in the bar-shaped mounting holes 5 by screws, the number of the vertical support plates 13 is two, the two vertical support plates 13 are respectively located at the long sides of the bar-shaped mounting holes 5 and fixed on the bottom wall of the bar-shaped mounting holes 5, two shaft rods 15 of the rotating piece are respectively penetrated in the corresponding vertical support plates 13 (the rotating holes are formed in the support plates 13), and the rotating piece rotates around the shaft rods 15. A horizontal support plate 14 is further fixed on the vertical support plate 13 through screws, and the horizontal support plate 14 is used for placing the rotating sheet B part 7. As shown in fig. 2, the lower surface of the rotating piece a portion 6 is hinged with a piston rod of a second air cylinder 16, and the second air cylinder 16 is fixed on a frame (not shown) by a conventional manner in the prior art. As shown in fig. 3, the upper surface of the rotor B7 is lower than the upper surface of the vertical mounting plate 19 to ensure that the rotor B7 does not interfere with the normal machining process of the ring 8 by the apparatus.

Referring to fig. 1, the number of the extrapolation units is two, and the extrapolation units are located on both sides of the horizontal column 2, and the two extrapolation units are symmetrically distributed to ensure that the two extrapolation units can symmetrically apply force to the ring 8, so that the ring 8 falls off the horizontal column 2. And, both the pushing-out units are located behind the upper part of the ring 8 to ensure that the rotating piece B7 contacts the upper part of the ring 8 and pushes the ring 8, so that the ring 8 can be pushed more efficiently (than in the case where the ring 8 is pushed at the lower part of the ring 8) to be successfully detached from the horizontal column 2.

With reference to fig. 1 and 4, the receiving unit includes a first rail 9, a second rail 11 and a collecting box 12 connected in sequence. The first rail 9 and the second rail 11 are fixed by screws, and guardrails can be arranged on the first rail 9 and the second rail 11 to prevent the ring-shaped object 8 from falling off, and fig. 4 shows the condition that the guardrails are arranged on the first rail 9 only. The free end of the second rail 11 is placed in a collecting bin 12 for collecting the processed rings 8. The first rail 9 is obliquely arranged, one end, far away from the third rail 11, of the first rail 9 is fixed on the vertical mounting plate 19 through a screw, and the first rail 9 is located below the horizontal column 2 and the ring 8 and used for receiving the ring 8 falling off from the horizontal column 2.

When the rolling device is used, the ring-shaped object 8 (the ring-shaped object 8-position synchronizer gear sleeve processed by the scheme is small in shape and is not large-sized) is hung on the horizontal column 2, and the rolling roller 1 is adjusted by using the rolling roller driving structure 10 (the structure in the prior art and the content in the non-scheme) to press the ring-shaped object 8. The first cylinder 3 is activated and its piston rod is moved towards the ring 8 so that the ring 8 is located in the limit groove 17. The outer edge of the rolling roller 1 drives the ring-shaped object 8 to rotate, and then the ring-shaped object is processed. After the machining is completed, the first cylinder 3 is started, the piston rod of the first cylinder moves towards the direction far away from the ring-shaped object 8, and the ring-shaped object 8 is not limited any more. The rolling roller driving mechanism 10 adjusts the rolling roller 1 to no longer press the ring 8, and then starts the second cylinder 16 (in an initial state, the piston rod moves upward to extend to a limit position, where the direction is the direction in fig. 3), the piston rod retracts, the rotating piece rotates, and the end of the rotating piece B portion 7 away from the second cylinder 16 moves toward the ring 8. The two rotating sheets B7 apply force to the ring-shaped object 8 together, the ring-shaped object 8 is pushed out from the horizontal column 2, the ring-shaped object 8 falls onto the first rail 9, the ring-shaped object 8 slides down to the collecting box 12 along the first rail 9, and automatic discharging of the processed ring-shaped object 8 is completed. The piston rod of the second cylinder 16 is then adjusted to an extended state in preparation for the next ring 8 to be machined.

One side of the limiting head 4 close to the ring 8 is provided with a limiting groove 17, and the limiting groove 17 is used for accommodating the ring 8. Under the condition that the ring 8 does not deviate left and right or front and back, the limiting groove 17 is not in contact with the ring 8, and the limiting groove 17 has a certain depth and width, so that the ring 8 is not limited by the groove when ring rolling is carried out (generally, the radius of the ring 8 is increased along with the ring rolling process). The purpose of the arrangement of the limiting head 4 is: when the rolling roller 1 drives the ring-shaped object 8 to rotate, the ring-shaped object 8 may deviate left and right (or forward and backward), so that the machining accuracy is affected to a certain extent, and the limiting groove 17 is used for preventing the ring-shaped object 8 from deviating left and right or forward and backward too much. The number of the first limiting units is two, and the first limiting units are respectively positioned on the left side and the right side of the ring-shaped object 8.
