[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Combine the following Figure 1 , describing an embodiment of the utility model.

[0026] According to an embodiment of the utility model, a ring forging transfer device is provided, comprising: a mounting frame 1, an internal support structure 2, an internal support drive assembly 3 and a transfer drive structure. The internal support structure 2 is slidably connected to the mounting frame 1, and a plurality of internal support structures 2 are arranged at intervals along the four sides of the mounting frame 1, and the plurality of internal support structures 2 have a folded position that approaches the center at the same time, and a support position that spreads outward at the same time. The internal support drive assembly 3 is transmission-connected to the plurality of internal support structures 2, so that the plurality of internal support structures 2 can switch between the folded position and the support position. The transfer drive structure is transmission-connected to the mounting frame 1.

[0027] When the forging blank needs to be transferred, the internal support driving assembly 3 drives several internal support structures 2 to spread outward at the same time, so that the several internal support structures 2 are supported on the inner annular surface of the forging blank at the same time, and then the transfer of the forging blank is realized under the drive of the transfer driving structure. Therefore, the internal support driving assembly 3 has different driving strokes for the internal support structure 2, so that the internal support structure 2 can be matched with forging blanks of different sizes to meet the transfer of forging blanks of various sizes.

[0028] It is worth noting that ring forgings have the production characteristics of small batches and multiple varieties. If the ring forging transfer device has a low mold change efficiency, it will greatly affect the production efficiency of the ring forgings. Therefore, how to efficiently and automatically achieve rapid mold change during the transfer of workpieces between processes is the basis for the automated production of ring forgings, and it is also an important issue for improving the efficiency of forging production workshops. The ring forging transfer device provided in this embodiment can adapt to ring forgings of different sizes and has high versatility. For most production scenarios (the size of the ring forgings is within the travel range of the inner support structure 2), there is no need to change the mold or make other adjustments, so that the working process can be carried out automatically and continuously, with high working stability and improved production efficiency.

[0029] It should be further explained that, by using the ring forging transfer device of this embodiment, the workpiece can be automatically picked up and transported, and the working process does not require human intervention, and the working process is stable, safe and reliable.

[0030] It is worth noting that the transfer drive structure can be a four-axis drive module or a robot, thereby driving the inner support structure 2 to move in different directions.

[0031] In one embodiment, Figure 1 As shown, the inner support driving assembly 3 includes a telescopic driving structure 301, a connecting structure 302 and a transmission structure 303. The fixed end of the telescopic driving structure 301 is connected to the mounting frame 1, the driving end of the telescopic driving structure 301 is connected to the connecting structure 302, the first end of the transmission structure 303 is hinged to the connecting structure 302, the second end of the transmission structure 303 is hinged to the inner support structure 2, and there are several transmission structures 303, and the several transmission structures 303 are arranged in a one-to-one correspondence with the several inner support structures 2. The several transmission structures 303 are connected to the telescopic driving structure 301 through the connecting structure 302, and one telescopic driving structure 301 can be used to drive several transmission structures 303 at the same time, and then drive several inner support structures 2 at the same time, and the overall structure is simple.

[0032] In one embodiment, the telescopic driving structure 301 is a driving cylinder, such as a hydraulic cylinder, an electric cylinder, etc.

[0033] It is worth mentioning that please refer to Figure 1 The telescopic driving structure 301 is arranged corresponding to the center of several inner supporting structures 2. In the folded position, several inner supporting structures 2 are arranged close to the telescopic driving structure 301 at the same time. In the supporting position, several inner supporting structures 2 are arranged away from the telescopic driving structure 301 at the same time.

[0034] Of course, in other alternative embodiments, the internal support drive assembly 3 may also be of other structural forms. For example, the internal support drive assembly 3 may include a plurality of linear drive structures, which are transmission-connected to a plurality of internal support structures 2. Furthermore, a plurality of linear drive structures simultaneously drive a plurality of internal support structures 2 to approach the center or spread outward along a straight line.

[0035] In one embodiment, Figure 1 As shown, a slide groove 101 is provided on the mounting frame 1, and a plurality of slide grooves 101 are provided. A plurality of inner support structures 2 are provided corresponding to the plurality of slide grooves 101. Under the drive of the inner support driving assembly 3, the inner support structure 2 can be slidably provided along the slide groove 101. By providing a plurality of slide grooves 101, a plurality of inner support structures 2 are guided and limited, thereby ensuring the stability of the inner support structure 2 during the movement and the accuracy of the position.

[0036] It is worth mentioning that please refer to Figure 1, the telescopic driving structure 301 is in the extended state, and the plurality of inner supporting structures 2 are in the retracted position. When the telescopic driving structure 301 is converted to the retracted state, the driving connection structure 302 moves upward, and at the same time drives the transmission structure 303 to rotate, so that the transmission structure 303 pushes the inner supporting structure 2 to slide outward along the slide groove 101, that is, to move toward the supporting position. When the telescopic driving structure 301 is converted to the extended state, the driving connection structure 302 moves downward, and at the same time drives the transmission structure 303 to rotate, so that the transmission structure 303 pulls the inner supporting structure 2 to slide inward along the slide groove 101, that is, to move toward the retracted position.

[0037] In one embodiment, Figure 1 As shown, the inner support structure 2 includes a support rod 201, a connecting pin 202 and a slider 203, the inner support driving assembly 3 is transmission-connected with the support rod 201, the connecting pin 202 connects the support rod 201 and the slider 203, and the slider 203 is slidably disposed in the slide slot 101. Further, the second end of the transmission structure 303 is hinged with the support rod 201.

[0038] In one embodiment, Figure 1 As shown, the outer peripheral surface of the slider 203 is a circular structure. By setting the slider 203 to a circular structure, the friction force of the slider 203 during the sliding process is reduced, and the smoothness of the sliding process is improved.

[0039] It is worth noting that the slider 203 is rotatably arranged, that is, the slider 203 is rotatably connected to the connecting pin 202, so the friction force of the slider 203 can be further reduced.

[0040] In one embodiment, Figure 1 As shown, the inner support structure 2 further includes a support head 204 , which is disposed at one end of the support rod 201 away from the mounting frame 1 .

[0041] It is worth noting that the support head 204 is in support and contact with the inner annular surface of the forging blank.

[0042] It should be further explained that the support head 204 can be set to a high temperature resistant material, so that the ring forging transfer device is suitable for transporting workpieces under high temperature conditions. That is, the ring forging transfer device of this embodiment can realize the transfer of ring forgings in a cold environment and a hot environment. It can be understood that by using the ring forging transfer device of this embodiment, the ring forgings in a high temperature state after forging and rolling can be directly transferred to the quenching process without waiting for the ring forgings to cool down, saving waiting time and avoiding the ring forgings from occupying the inventory space during the waiting process.

[0043] In one embodiment, the support head 204 is rotatably connected to the support rod 201. By rotatably setting the support head 204, the angle of the support head 204 can be adjusted when the support head 204 contacts the inner annular surface of the forging blank, ensuring that the support head 204 contacts the forging blank effectively and improving the stability of the forging blank support.

[0044] In one embodiment, Figure 1 As shown, the ring forging transfer device further includes a base 4 and a buffer structure 5, the base 4 is spaced apart from the mounting frame 1, the transfer drive structure is transmission-connected to the base 4, and the buffer structure 5 is connected between the base 4 and the mounting frame 1. By providing the buffer structure 5, the impact on the base 4 and the transfer drive structure during material removal is reduced, thereby extending the service life of the transfer device.

[0045] In one embodiment, Figure 1 As shown, the buffer structure 5 includes a guide member 501, an elastic member 502 and a limit member 503. The elastic member 502 is sleeved on the outside of the guide member 501 and is located between the base 4 and the mounting frame 1. One end of the guide member 501 is fixedly connected to the mounting frame 1, and the other end of the guide member 501 passes through the base 4. The limit member 503 is arranged on the guide member 501 and is located on the side of the base 4 away from the mounting frame 1. The base 4 is movably arranged along the guide member 501.

[0046] Of course, in other alternative embodiments, one end of the guide member 501 can be fixedly connected to the base 4, the other end of the guide member 501 passes through the mounting frame 1, the limit member 503 is arranged on the guide member 501 and is located on the side of the mounting frame 1 away from the base 4, and the mounting frame 1 is movably arranged along the guide member 501; or, the two ends of the guide member 501 pass through the mounting frame 1 and the base 4 respectively, the side of the mounting frame 1 away from the base 4 and the side of the base 4 away from the mounting frame 1 are both provided with the limit members 503, and the mounting frame 1 and the base 4 are both movably arranged along the guide member 501.

[0047] In one embodiment, Figure 1 As shown, the guide member 501 is a bolt, the limiting member 503 is a nut, and the nut is threadedly connected to the bolt.

[0048] In one embodiment, Figure 1 As shown, a plurality of buffer structures 5 are arranged at intervals around the base 4 .

[0049] When using the ring forging transfer device of this embodiment, first, a number of internal support structures 2 are in the folded position, and under the drive of the transfer drive structure, the several internal support structures 2 are moved to the inside of the forging blank to be transferred; then, the telescopic drive structure 301 is retracted, so that the several internal support structures 2 are all moved outward, and the support head 204 is supported and abutted against the inner ring surface of the forging blank to be transferred, so as to realize the material removal of the forging blank to be transferred; finally, under the drive of the transfer drive structure, the forging blank to be transferred is driven to move to the predetermined position, and the telescopic drive structure 301 is extended, so that the several internal support structures 2 are all moved inward for folding, and the several support heads 204 cancel the abutment against the inner ring surface of the forging blank, and under the drive of the transfer drive structure, the next transfer can be carried out again.

[0050] When the diameter of the forging blank to be transferred is small, when the forging blank to be transferred is taken, the retraction stroke of the telescopic driving structure 301 is small, thereby the driving stroke of the inner support structure 2 is small, so that a plurality of support heads 204 can support and abut the inner ring surface of the forging blank to be transferred; when the production line is changed to process ring forgings with a larger diameter, when the forging blank to be transferred is taken, it is only necessary to increase the retraction stroke of the telescopic driving structure 301, thereby increasing the driving stroke of the inner support structure 2, so that a plurality of support heads 204 can support and abut the inner ring surface of the forging blank to be transferred.

[0051] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
