Description

TECHNICAL FIELD

[0002] Die forging is a forging method that makes metal billets plastically deform in a die under the action of external force and fill the die cavity to obtain a forged piece with a required shape and size. Most metals are die forged in a hot state.

[0058] In one embodiment of the present application, as shown in Figures 1 to 12 A horizontal hydraulic die forging machine is provided, which includes a pressing device 30 and an opening and closing mold device 20.

[0059] The pressing device 30 includes a workbench 10, a feeding mechanism 3, a hydraulic station 50, a feeding mechanism 40 and a vibration motor 33. The feeding mechanism 40 is arranged on one side of the workbench 10 and is used to pour molten metal into the feeding mechanism 3. The feeding mechanism 3 is horizontally arranged on the workbench 10. The hydraulic station 50 is arranged on one side of the feeding mechanism 3 and is used to extrude the molten metal in the feeding mechanism 3. The vibration motor 33 is arranged on the feeding mechanism 3 and is used to vibrate the feeding mechanism 3.

[0060] The opening and closing mold device 20 is horizontally arranged on the workbench 10. The opening and closing mold device 20 includes a forging die. The forging die is in communication with the feeding mechanism 3 and is used to form a part.

[0061] Specifically, in use, the feeding mechanism 40 pours the metal liquid into the feeding mechanism 3, the vibration motor 33 is started to make the feeding mechanism 3 vibrate, so that the gas in the metal liquid is separated from the metal liquid, and the gas in the metal liquid is discharged, then the hydraulic station 50 extrudes the metal liquid in the feeding mechanism 3 into the forging die to be shaped, the mold opening and closing device 20 drives the forging die to open, the shaped part is taken out, the metal liquid is poured into the feeding mechanism 40 arranged horizontally, and the gas in the feeding mechanism 3 is separated from the metal liquid through the vibration motor 33, so that the metal liquid entering the forging die does not enter together with the gas to cause unqualified products, and the feeding mechanism 3 arranged horizontally does not need to swing, the metal liquid is directly extruded into the forging die through the hydraulic station 50, the time of the metal liquid entering the forging die is reduced, the production efficiency is improved, and the phenomenon of excessive cold material in the feeding process is avoided.

[0062] In another embodiment of the present application, as shown in Figures 1 to 6 The feeding mechanism 3 includes a feeding pipe 31 and a feeding hopper 32, the feeding pipe 31 includes a feeding part 313 and a feeding part 314, the feeding pipe 31 has a cavity 311 penetrating through the feeding part 313 and the feeding part 314, the feeding part 313 is provided with a horizontal mounting surface 315, the mounting surface 315 is provided with a discharging hole 316, the discharging hole 316 communicates with the feeding part 314, the discharging hole 316 is arranged in an inclined manner from top to bottom and is tangent to the inner wall of the cavity 311, and the feeding hopper 32 is installed on the discharging hole 316.

[0063] Specifically, in use, the metal liquid is poured into the feeding hopper 32, because the discharging hole 316 is arranged in an inclined manner, when the metal liquid is poured into the feeding hopper 32, the metal liquid flows downward along the side wall of the feeding hopper 32 to the discharging hole 316, because the discharging hole 316 is tangent to the inner wall of the cavity 311, as shown in Figure 5 The metal liquid flows along the side wall of the discharging hole 316 to the side wall of the cavity 311 in the feeding part 313 and flows downward along the inner wall of the cavity 311, so that the air in the cavity in the feeding part 313 is discharged to the outside of the cavity 311 in the feeding part 313 along the other side wall of the feeding part 313 to the discharging hole 316, so that the air in the feeding part 314 is prevented from entering the die when the metal liquid is poured, the air exhaust is simple, and the quality of the produced products is guaranteed.

[0064] In another embodiment of the present application, as shown in Figures 3 to 4As shown, the outer side wall of the feeding part 314 is provided with a plurality of rows of exhaust holes 312 for exhausting gas, which are in communication with the cavity 311; and the vibration motor 33 is arranged on the outer side wall of the feeding part 314.

[0065] Specifically, in use, the feeding mechanism 40 pours the molten metal onto the lower hopper 32, the molten metal enters the cavity 311 along the lower hopper 32, the movable end of the first hydraulic cylinder 34 extrudes the molten metal in the cavity 311 into the cavity 211, in the extrusion process, the vibration motor 33 works to make the feeding pipe 31 vibrate, so that the molten metal and the gas in the cavity 311 are separated, the gas is exhausted from the exhaust holes 312 out of the feeding pipe 31, so as to avoid the molten metal and the gas entering the cavity 211 together to cause unqualified products, the molten metal is directly extruded into the cavity 211 by the first hydraulic cylinder 34, which saves the swing time of the swing type injection mechanism, thereby reducing the time of the molten metal entering the cavity 211, thereby reducing the generation of cold material, and the transversely arranged feeding pipe 31 is shorter in length than the swing type feeding pipe 31, the extrusion distance is shortened, and the generation of cold material in the extrusion process is reduced.

[0066] Further, as shown in the drawings, Figures 3 to 4 The end of the feeding part 313 away from the feeding part 314 is also provided with a mounting part 317, and the mounting part 317 is also provided with an annular boss 318 for limiting, specifically, the cavity 311 is in communication with the mold opening and closing device 20 by connecting the mounting part 317 with the fixed mold 22, and the annular boss 318 is used for limiting the feeding pipe 31, so that the feeding pipe 31 will not be separated from the mold opening and closing device 20 when the movable end of the hydraulic cylinder extrudes the molten metal in the cavity 311.

[0067] Further, the feeding pipe 31 is an integral molding structure, specifically, the integral molding feeding pipe 31 facilitates manufacturing and production, reduces the difficulty of processing, and improves production efficiency.

[0068] In another embodiment of the present application, as shown in the drawings, Figure 5 The side wall of the lower hole 316 and the inner wall of the cavity 311 are in a "6" structure. Specifically, since the left side wall of the lower hole 316 and the side wall of the inner cavity of the feeding part 313 are in a tangent structure, the molten metal can flow from the funnel along the left side wall of the lower hole 316 to the left side wall of the inner cavity of the feeding part 313, and when the molten metal enters the feeding part 313, the gas in the inner cavity of the feeding part 313 can be further discharged out of the inner cavity of the feeding part 313, so as to reduce the air in the molten metal in the inner cavity of the feeding part 313.

[0069] In another embodiment of the present application, as shown in the drawings, Figures 3 to 4As shown, the air vent 312 is arranged on the feeding part 314. Specifically, the metal liquid flows into the feeding part 313 from the lower hopper 32, and is extruded to the feeding part 314 under the extrusion of the hydraulic cylinder. Since the volume of the cavity 311 is reduced, the air will be discharged from the air vent 312 of the feeding part 314.

[0070] Further, the diameter of the air vent 312 is 1mm-2mm. In the embodiment, the diameter of the air vent 312 is preferably 1mm, so that the metal liquid will not overflow from the air vent 312 when passing through the feeding part 314.

[0071] In another embodiment of the present application, as shown in Figures 3 to 4 the air vent 312 is arranged on the two ends of the feeding pipe 31 with the widest horizontal plane. Specifically, since the density of the gas is less than that of the metal liquid, the gas will always be above the metal liquid after the vibration of the vibration motor 33. Arranging the air vent 312 on the two ends of the feeding part with the widest horizontal plane can sufficiently discharge the air in the inner cavity of the feeding part 314, so as to reduce the difficulty of discharging the air.

[0072] In another embodiment of the present application, as shown in Figure 6 the lower hopper 32 comprises a leakage body 321 and a leakage pipe 322. The leakage body 321 is a conical structure surrounded by four sides, wherein the two adjacent sides are inclined away from the feeding part 314. Specifically, since the two sides are inclined away from the fixed frame 23, the length of the two sides is greater than that of the other two sides. Therefore, the metal liquid flows into the cavity 311 along the two sides with greater length, and the flow rate of the metal liquid is slower. In this way, it is ensured that the slowly flowing metal liquid can flow along the side wall of the inner cavity of the feeding part 313.

[0073] In another embodiment of the present application, as shown in Figures 7 to 10As shown, the forging die comprises a movable die 21 and a fixed die 22, the movable die 21 is provided with a cavity 211, the fixed die 22 is provided with a core (not shown in the figure) matched with the cavity 211, the fixed die 22 is provided with a pouring gate 222, the feeding part 314 communicates with the pouring gate 222; the forging die further comprises a cold material extrusion core 212, the cold material extrusion core 212 comprises a first cylinder 2121 and a second cylinder 2122, the axis of the first cylinder 2121 coincides with the axis of the second cylinder 2122, the diameter of the first cylinder 2121 is smaller than the hole diameter of the second cylinder 2122, the movable die 21 is provided with a mounting groove (not marked in the figure), the second cylinder 2122 is inlaid in the mounting groove, four threaded holes (not marked in the figure) are uniformly and spacedly arranged on the back surface of the second cylinder 2122, the mounting groove is provided with a positioning hole corresponding to each threaded hole, and a fixing screw is sequentially screwed through the positioning hole and the threaded hole to be threadedly connected so as to fix the second cylinder 2122 in the mounting groove, the first cylinder 2121 is arranged on the front end surface of the second cylinder 2122 and extends out of the movable die 21, the axis of the second cylinder 2122 coincides with the axis of the pouring gate 222, the first cylinder 2121 and the second cylinder 2122 are provided with a notch 2124, the notch 2124 communicates with the cavity 211, and when the die is closed, the front end surface of the first cylinder 2121, the front end surface of the second cylinder 2122 and the inner wall of the pouring gate 222 form a cold material chamber 214. Specifically, in operation, the mold opening and closing device 20 causes the movable die 21 and the fixed die 22 to be closed, and the injection device 30 causes the molten metal to enter the cavity 211 from the pouring gate 222, when the molten metal passes through the pouring gate 222, it first contacts the cold material extrusion core 212, the temperature is lowered to form cold material, after the cold material fills the cold material chamber 214, the molten metal with a higher temperature enters the cavity 211 from the notch 2124 of the first cylinder 2121 and the notch 2124 of the second cylinder 2122 to form a shape, the equipment is opened to take out the formed blank, and one-time die forging is completed; due to the cold material chamber 214 formed by the front end surface of the first cylinder 2121, the front end surface of the second cylinder 2122 and the inner wall of the pouring gate 222, the molten metal first contacting the cold material chamber 214 stays in the cold material chamber 214, after the cold material chamber 214 is filled, the molten metal with a higher temperature flows into the cavity 211 from the notch 2124, thereby avoiding that the cold material directly enters the cavity 211, avoiding defects such as cold separation and cracking caused by the cold material entering the cavity 211, improving the yield of products and the financial income of the company.

[0074] In another embodiment of the present application, as Figures 7 to 10As shown, the front end surface of the second cylinder 2122 is flush with the parting surface of the movable mold 21. Specifically, the diameter of the second cylinder 2122 is the same as the hole diameter of the pouring gate 222, when the movable mold 21 and the fixed mold 22 are closed, the first cylinder 2121 extends into the pouring gate 222, and the parting surface of the fixed mold 22 does not collide with the second cylinder 2122, so as to avoid damage to the second cylinder 2122 and the fixed mold 22, thereby prolonging the service stability of the cold material extrusion core 212 and the fixed mold 22.

[0075] In another embodiment of the present application, as shown in Figure 10 As shown, the rear end surface of the second cylinder 2122 is also provided with a third cylinder 2123 for positioning. Specifically, the mounting groove is provided with a positioning groove matched with the third cylinder 2123, and the third cylinder 2123 extends into the positioning groove, so as to facilitate the installation of the second cylinder 2122.

[0076] In another embodiment of the present application, as shown in Figures 7 to 10 As shown, the gap 2124 and the cavity 211 are also provided with a flow distribution groove 215, which communicates the gap 2124 and the cavity 211. One end of the flow distribution groove 215 communicating with the cavity 211 is an inner gate 216, and the groove width of the flow distribution groove 215 is greater than the width of the inner gate 216, so as to avoid the shortcoming that the inner gate 216 is too small to remove air.

[0077] Further, the movable mold 21 is also provided with an exhaust groove (not shown in the figure), and specifically, when the molten metal enters the cavity 211 from the flow distribution groove 215 and fills the cavity 211, the air in the cavity 211 is discharged out of the cavity 211 through the exhaust groove, so as to prevent the air from causing the molten metal to be not filled.

[0078] In another embodiment of the present application, as shown in Figure 7 As shown, the movable mold frame 28 is also provided with a first accommodating cavity, and the movable mold 21 is arranged in the first accommodating cavity. Specifically, the first accommodating cavity is provided with a plurality of positioning holes, and the movable mold 21 is provided with a threaded hole corresponding to each positioning hole. The fixed bolts are sequentially connected through the positioning holes and the threaded holes to fix the movable mold 21 in the first accommodating cavity, so as to facilitate the installation of the movable mold 21.

[0079] In another embodiment of the present application, as shown in Figure 7As shown, the fixed mold frame 29 is provided with a second accommodating cavity (not shown in the figure), and the fixed mold 22 is arranged in the second accommodating cavity. Specifically, the second accommodating cavity is provided with a plurality of positioning holes, and the fixed mold 22 is provided with a threaded hole corresponding to each positioning hole.
