[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0032] like Figures 1 to 3 As shown, a composite cooling and exhaust structure of a precision forging die according to an embodiment of the present invention includes a mounting seat 1, a plurality of support rods 11 are provided at the bottom of the mounting seat 1, both ends of the support rods 11 are fixedly mounted with mounting seats 1, a first telescopic rod 14 is fixedly mounted at the bottom center of the top mounting seat 1 of the support rod 11, an upper forging block 12 is fixedly mounted at the bottom of the first telescopic rod 14, a lower forging block 15 is provided at the top center of the mounting seat 1 at the bottom of the support rod 11, forging grooves 13 are provided inside the upper forging block 12 and the lower forging block 15, a cooling and exhaust device 2 is provided inside the lower forging block 15, a conveying device 3 is provided inside the mounting seat 1 at the bottom of the support rod 11, the cooling and exhaust device 2 is used for exhausting and slag removal after extrusion of the upper forging block 12 and the lower forging block 15, and the conveying device 3 is used for conveying the oxide scale inside the lower forging block 15;

[0033] like Figures 4 to 7As shown, the cooling exhaust device 2 includes an extrusion sealing block 21, a cleaning piece 22, an adjusting piece 23, a first threaded rod 24, and a power piece 25. The extrusion sealing block 21 slides inside the lower forging block 15, and the bottom of the extrusion sealing block 21 is fixedly installed with a first threaded rod 24. The upper part of the first threaded rod 24 is rotatably installed with a cleaning piece 22, and the bottom of the cleaning piece 22 is fixedly installed with an adjusting piece 23. The bottom of the first threaded rod 24 is provided with a power piece 25, and the power piece 25 is fixedly installed inside the mounting seat 1. The lifting of the power piece 25 drives the first threaded rod 24 to rotate, and the rotation of the first threaded rod 24 drives the extrusion sealing block 21 to lift and the cleaning piece 22 to extend and retract. The lifting of the extrusion sealing block 21 pushes out the extruded metal piece inside the lower forging block 15, and the cleaning piece 22 removes slag from the exhaust hole on the lower forging block 15.

[0034] It should be noted that when the die is forging, the metal heated to a high temperature is placed inside the forging groove 13, and then the first telescopic rod 14 is started to drive the upper forging block 12 to descend, so that the upper forging block 12 and the lower forging block 15 are close to each other, so that the heated metal conforms to the shape of the forging groove 13 inside the upper forging block 12 and the lower forging block 15. In this process, the heated metal does not necessarily conform to the shape of the forging groove 13. During the extrusion process, the metal is deformed and fits with the forging groove 13. During the fitting contact process, a closed space is formed, which causes the gas to be compressed, so that the metal after extrusion forms a groove or cavity. If the squeezed gas cannot be discharged in time, it may cause local overheating and more serious metal deformation. Therefore, the following improvements are made;

[0035] A spring is provided at the bottom of the lower forging block 15, and an exhaust hole is provided inside the lower forging block 15, so that during the extrusion process, gas can be discharged from the exhaust hole, and a cooling exhaust device 2 is provided at the bottom of the exhaust hole on the lower forging block 15. When the first telescopic rod 14 drives the upper forging block 12 to descend, the lower forging block 15 moves downward. Under the action of the spring, even if the upper forging block 12 is not fully engaged with the lower forging block 15, the metal will be deformed, thereby achieving the exhaust effect. However, the exhaust hole cannot be set too large, otherwise it may cause large marks to form on the metal surface, which requires further Processing, and if the exhaust hole is set too small, it is easy to be blocked by the oxide scale formed after the metal is squeezed, causing the problem of exhaust difficulty. Therefore, an extrusion sealing block 21 is provided inside the lower forging block 15. When the lower forging block 15 drops to the bottom, the forging groove 13 can be completely sealed up and down, thereby achieving the effect of die forging. When the lower forging block 15 is not in contact with the top surface of the lower mounting seat 1, the exhaust hole on the lower forging block 15 is in a ventilated state, which is convenient for gas discharge. When the extrusion sealing block 21 is fully engaged with the surface of the forging groove 13, the lower forging block 15 squeezes the power piece 25, so that The power piece 25 rotates, and the power piece 25 can drive the adjusting piece 23 to rotate. The connection position of the power piece 25 and the adjusting piece 23 is provided with a ratchet structure. Therefore, when the lower forging block 15 descends, it will not drive the first threaded rod 24 to rotate and the cleaning piece 22 to rotate. When the lower forging block 15 rises after extrusion, it can drive the power piece 25 to rotate, and the rotation of the power piece 25 drives the first threaded rod 24 to rise a certain distance, thereby ejecting the extruded metal part, facilitating the demoulding of the metal part. The rotation of the adjusting piece 23 synchronously drives the cleaning piece 22 to rotate, so that the cleaning piece 22 is subjected to the centrifugal force of the rotation, and the cleaning piece 22 is cleaned. The part 22 extends out to clean the vent holes inside the lower forging block 15 to prevent the oxide scale from clogging the vent holes inside the lower forging block 15 until the lower forging block 15 is reset. The extrusion sealing block 21 is lowered by gravity, and the positions of the extrusion sealing block 21 and the cleaning part 22 can be reset until the next round of extrusion. The extrusion sealing block 21 seals the lower forging block 15, and the cleaning part 22 cleans the vent holes, thereby achieving exhaust and preventing the forging groove 13 from being completely sealed during the extrusion process, resulting in the formation of gas extrusion grooves in the metal parts, thereby improving the yield of metal forging.

[0036] like Figures 2 to 4As shown, the lower forging block 15 is provided with an exhaust port 151 inside, and a second groove 152 is provided at the bottom of the exhaust port 151. The extrusion sealing block 21 slides inside the exhaust port 151 and the second groove 152. A groove is provided at the inner center of the lower forging block 15, and a first spring 154 is fixedly installed inside the groove. A bottom fixing block 155 is fixedly installed at the bottom end of the first spring 154. The bottom fixing block 155 is fixedly installed on the mounting seat 1. The lower forging block 15 slides outside the bottom fixing block 155. A second slide groove 153 is provided at the bottom of the second groove 152, and the power part 25 is slidably connected to the second slide groove 153.

[0037] It should be noted that the exhaust holes mentioned in this article refer to Figure 4 The exhaust port 151 in the middle, and when the lower forging block 15 descends, the extrusion sealing block 21 does not engage with the exhaust port 151, so it can have the effect of exhaust, and the first spring 154 can squeeze the lower forging block 15 downward on the upper forging block 12, thereby squeezing the metal part, so that the metal part can be deformed until the bottom of the lower forging block 15 fits with the mounting seat 1 at the lower part of the support rod 11, thereby completing the effect of extrusion die forging of the metal part, and the second slide groove 153 can limit the power part 25, so that when the lower forging block 15 descends, the power part 25 is squeezed, thereby driving the extrusion sealing block 21 to rise and the cleaning part 22 to clean the oxide scale on the inner wall of the exhaust port 151.

[0038] like Figure 6 and Figure 9 As shown, the cleaning member 22 includes a first circular ring 221 rotatably mounted on the bottom of the extruded sealing block 21, a plurality of grooves are provided on the first circular ring 221, a second telescopic rod 222 and a rotating plate 225 are provided on the groove, a telescopic fixed plate 224 is fixedly mounted on the end of the second telescopic rod 222, a plurality of cleaning brushes 223 are fixedly mounted on the side of the telescopic fixed plate 224, a rotating groove 226 is provided at the lower portion of the telescopic fixed plate 224, and the interior of the rotating groove 226 is rotatably mounted to the end of the rotating plate 225.

[0039] It should be noted that when the power part 25 rotates and drives the first ring 221 to rotate, it can drive the telescopic fixing plate 224 and the cleaning brush 223 on the first ring 221 to rotate, and a torsion spring is provided at the connection position between the rotating plate 225 and the rotating groove 226 at the bottom of the telescopic fixing plate 224, so that when the first ring 221 is in a stationary state, the telescopic fixing plate 224 is close to the center of the first ring 221. Therefore, when the telescopic fixing plate 224 rotates, the telescopic fixing plate 224 is subjected to centrifugal force and can be extended, thereby driving the cleaning brush 223 to extend, and the surface of the exhaust port 151 can be cleaned to prevent the oxide scale from clogging the inside of the exhaust port 151, so that the exhaust port 151 has a stable exhaust effect.

[0040] like Figures 5 to 9 As shown, the adjusting member 23 includes a first rotating ring 231 fixedly mounted on the bottom of the first circular ring 221, a first connecting rod 232 fixedly mounted on the outside of the first rotating ring 231, a first fixed ring 233 fixedly mounted on the bottom of the first connecting rod 232, a second ratchet ring 234 is provided at the bottom of the first fixed ring 233, a second connecting rod 235 fixedly mounted on the bottom of the second ratchet ring 234, a first protrusion 236 fixedly mounted on the bottom of the second connecting rod 235, a limiting rotating ring 237 fixedly mounted on the first protrusion 236, the limiting rotating ring 237 is rotatably mounted on the power member 25, and the limiting rotating ring 237 is threadedly connected to the first threaded rod 24.

[0041] It should be noted that a ratchet mechanism is provided at the connection position of the first fixed ring 233 and the second ratchet ring 234. Therefore, when the power member 25 descends and drives the first protrusion 236 and the second connecting rod 235 to rotate, the first fixed ring 233 does not produce a rotating effect. When the power member 25 is reset, it can drive the first protrusion 236 and the second connecting rod 235 to rotate in the opposite direction, thereby driving the second ratchet ring 234 and the first fixed ring 233 and the first rotating ring 231 to rotate, so that the cleaning member 22 is extended by centrifugal force, which can have the effect of cleaning the interior of the exhaust port 151.

[0042] like Figures 5 to 7 As shown, the power part 25 includes a second limit plate 253 fixedly mounted on the mounting seat 1, a second ratchet 254 is rotatably mounted inside the second limit plate 253, a second spring 251 is fixedly mounted on the top of the second ratchet 254, a first power rod 252 is fixedly mounted on the top of the second spring 251, the first power rod 252 slides inside the second slide groove 153, and the first power rod 252 is threadedly connected to the limit rotating ring 237.

[0043] It should be noted that the first power rod 252 is threadedly mounted on the outside of the limiting rotating ring 237, and the first power rod 252 slides inside the second sliding groove 153. Therefore, when the first power rod 252 is raised or lowered, it can drive the limiting rotating ring 237 and the first protrusion 236 to rotate. The connection position between the limiting rotating ring 237 and the first threaded rod 24 is provided with a torsion spring, which does not drive the first threaded rod 24 to rotate and rise. When the first power rod 252 is reset by the elastic force of the second spring 251, it can drive the limiting rotating ring 237 to rotate in the opposite direction, thereby By moving the first threaded rod 24 up and the first fixing ring 233 to rotate, the first threaded rod 24 can be driven to rise, and at the same time, the extrusion sealing block 21 can be driven to rise, and the metal parts after extrusion can be ejected. Then, the first circular ring 221 is driven to rotate by the first rotating ring 231, which can drive the telescopic fixing plate 224 and the cleaning brush 223 to clean the interior of the exhaust port 151, and maintain the exhaust effect of the exhaust port 151. After exhaust, the gas is not compressed, and the relative positions of the metal parts inside the forging groove 13 will cool down instead of heating up, thereby achieving the effect of cooling exhaust.

[0044] like Figures 7 to 9 As shown, the conveying device 3 includes a first rotating rod 31 rotatably mounted inside the mounting base 1, a conveying reel 33 is fixedly mounted on the outside of the first rotating rod 31, and a bottom storage groove 16 is provided inside the bottom mounting base 1 of the support rod 11, and the bottom storage groove 16 is located directly below the cooling exhaust device 2.

[0045] It should be noted that after the cleaning piece 22 cleans the oxide scale inside the exhaust port 151, the oxide scale falls into the bottom storage tank 16 through the second groove 152. By using a motor to drive the first rotating rod 31 to rotate, the oxide scale can be transported out of the bottom storage tank 16, thereby facilitating the collection and cleaning of the oxide scale.

[0046] like Figures 7 to 9 As shown, a first gear 32 is fixedly mounted on the outside of the first rotating rod 31 , and a first tooth 238 is fixedly mounted on the bottom of the limiting rotating ring 237 , and the first tooth 238 is engaged with the first gear 32 .

[0047] It should be noted that a first tooth 238 is provided at the bottom of the limiting rotating ring 237, and a ratchet mechanism is also provided at the bottom of the limiting rotating ring 237, so that the first tooth 238 rotates in one direction. Therefore, when the ratchet mechanism at the bottom of the limiting rotating ring 237 rotates and drives the first tooth 238 to rotate, so that the first tooth 238 engages with the first gear 32, the oxide scale can be transported out of the bottom storage groove 16.

[0048] like Figures 4 and 5 ,like Figure 8As shown, the maximum distance between the two cleaning brushes 223 is greater than the inner diameter of the exhaust port 151 , and the maximum distance between the two telescopic fixing plates 224 is smaller than the inner diameter of the exhaust port 151 .

[0049] It should be noted that the maximum distance between the two cleaning brushes 223 is greater than the inner diameter of the exhaust port 151, and the maximum distance between the two telescopic fixing plates 224 is smaller than the inner diameter of the exhaust port 151. When the cleaning brush 223 is extended by centrifugal force, it can drive the cleaning brush 223 to clean the inner wall of the exhaust port 151.

[0050] like Figures 4 to 6 ,like Figure 8 As shown, the shape of the extrusion sealing block 21 is the same as the splicing shape of the forging groove 13 set inside the lower forging block 15.

[0051] It should be noted that the shape of the extrusion sealing block 21 is the same as the splicing shape of the forging groove 13 set inside the lower forging block 15. When the extrusion sealing block 21 rises, it can engage with the forging groove 13 to prevent the formation of marks after the metal parts are extruded.

[0052] like Figures 4 to 6 As shown, the diameter of the extrusion sealing block 21 is the same as the diameter of the exhaust port 151 , and the diameter of the first fixing ring 233 is smaller than the diameter of the extrusion sealing block 21 .

[0053] It should be noted that the diameter of the extrusion sealing block 21 is the same as the diameter of the exhaust port 151, and the diameter of the first fixing ring 233 is smaller than the diameter of the extrusion sealing block 21, so that the adjustment member 23 will not be hindered by the exhaust port 151 when it is raised or lowered, thereby improving the stability of the device operation.

[0054] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by the present invention.
