[0031] Embodiment 1:

[0032] The embodiment discloses an automatic indexing die, and the overall structure schematic diagram of the automatic indexing die of the embodiment is as shown in Figure 1 The technical scheme of the embodiment is specifically described as follows:

[0033] The automatic indexing die of the embodiment includes rotary indexing mechanism 2.

The indexing tray 26 is provided with 120-degree evenly divided proximity magnetic nails, and mounting holes suitable for locating rings of various sizes are reserved. The pinion 23 and the gear wheel 24 are further provided with gear cover 25.

[0034] The specific working principle of the rotary indexing mechanism 2 of the embodiment is described as follows:

[0035] Before rotary indexing, the servo motor 21 resets to find the origin.

[0036] When rotary indexing, the servo motor 21 rotates according to the set value, and through the gear transmission ratio, the locating ring 27 rotates the parts to be machined by a set angle to complete the workpiece indexing work. According to the above process, the machined parts can be divided into three equal parts by completing indexing twice. Then the back-to-origin operation is completed during the gap of the taking and placing operations, and the preparation for the machining of the next part is completed.

[0037] The automatic change of the angle from zero degrees, 120 degrees and 240 degrees, and the spring energy storage and release accompanying the punching process, are the fundamental reasons for the automatic indexing die to complete the automatic indexing and punching.

[0038] The automatic indexing die of the embodiment further comprises a die mechanism 1, which comprises a movable die frame 11, a female die 12, a male die 13, a cantilever 14 and a fixed die frame 15, the female die 12 is fixed on the movable die frame 11, the cantilever 14 is connected to the fixed die frame 15, the movable die frame 11 is oppositely arranged with the fixed die frame 15, the male die 13 is oppositely arranged with the female die 12, the male die 13 is pressed into the female die cavity of the female die 12, and a structure diagram of the die mechanism 1 is shown in Figure 3 . Figure 3 The precision guide sleeve 16, the support 17 and the guide column 18 in the fixed die frame 15 are used to support the movable die frame 11 and the female die 12 to smoothly move left and right.

[0039] The die mechanism 1 of the embodiment is in a horizontal structure, which is convenient for automatic processing. The die mechanism 1 can be separately disassembled, which not only improves the operation efficiency of the operator, but also can more accurately position the parts that need to be replaced or repaired, avoiding large-scale replacement and maintenance of the entire automatic indexing die. The fixed die frame 15 is further provided with a fixing groove.

[0040] The automatic indexing die of the embodiment further comprises a spring ejection material withdrawal mechanism 3, which comprises a spring large support plate 31, a spring small support plate 32, a sliding block 33, a sliding plate 34 and a sliding rail 35, the sliding plate 34 is provided with a sliding bearing copper sleeve, which is connected with the large gear 24 (specifically, the sliding bearing copper sleeve is rotationally connected with the sliding bearing part of the large gear 24), the spring large support plate 31 is connected with the spring small support plate 32, the sliding rail 35 is provided with the sliding plate 34, and the sliding plate 34 is provided with the sliding block 33, wherein the large gear 24 is connected with the sliding plate 34 through the sliding bearing, the sliding bearing not only has high bearing capacity and can bear the large load generated during the working process of the large gear 24 and the sliding plate 34, but also will not produce rolling sound during the working process, and the noise is relatively small, thereby making the overall equipment work more stably. A structure diagram of the spring ejection material withdrawal mechanism 3 is shown in Figure 4 .

[0041] The rotary indexing mechanism 2 and the spring ejection material withdrawal mechanism 3 of the embodiment are integrated. The integrated design can reduce the overall area occupied by the automatic indexing die, save production space, reduce production cost, and enhance the flexibility of the overall automatic indexing die equipment.

[0042] The automatic indexing die of the embodiment further comprises an indexing die body, and the spring ejection material withdrawal mechanism 3 is fixed on the indexing die body table to ensure that the spring ejection material withdrawal mechanism 3 can stably and reliably work.

[0043] The specific working principle of the punch tooth of the automatic indexing die of the embodiment is as follows:

[0044] Before the punch tooth, the servo motor 21 is at the original position, the sliding plate 34 is at the original position, and the movable die frame 11 is at the original position.

[0045] When the punch teeth, the driving dynamic die frame 11 moves forward, when the concave die 12 encounters the positioning ring 27, (at this time the positioning ring has been provided with a sealing ring), the positioning ring 7 is pushed forward together. When encountering the convex die 13, the convex die 13 passes through the strip-shaped through hole on the positioning ring 27, and is abutted on the side wall of the sealing ring, at this time the concave die 12 continues to move forward, the side wall of the sealing ring is cut by the shearing action of the convex die 13 and the concave die 12, and simultaneously drives the slide plate 34 to move forward, the slide plate 34 is connected to the spring small support plate 32 to compress the spring, so that the spring stores energy. When there is a tooth cutting instruction, the driving dynamic die frame 11 moves backward, the concave die 12 retreats to the original position, the spring releases energy, the slide plate 34 is pushed to the original position, and the material is pushed out from the convex die 13, so that the material is discharged. At this time, the servo motor 21 rotates, drives the large gear 24 to rotate, and the large gear 24 drives the positioning ring 27 to rotate 120 degrees and stop. The above process is repeated to punch the second tooth. The above process is repeated to punch the third tooth. After the third tooth is punched, the servo motor 21 is reset in reverse. Each mechanical mechanism returns to the original position, ready to receive the second sealing ring for punching.

[0046] The specific working principle of the automatic indexing die punching of the embodiment is as follows:

[0047] When punching, the concave die 12 moves forward under the power, when encountering the part, the part is pushed forward, and the positioning ring 27, the large gear 24 supporting the positioning ring 27 and the slide plate 34 are driven to move forward, and after encountering the fixed convex die 13, the convex die 13 pushes the part into the concave die 12 to realize punching, and the spring stores energy. When the concave die 12 retreats after punching, the spring releases energy, the slide plate 34 returns to the original position, the rotary indexing mechanism 2 installed on the slide plate 34 returns to the original position, and the rotary indexing mechanism also returns to the original position, ready for the next punching.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or replaced, without departing from the spirit and scope of the present application.
