Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic forging, and in particular relates to a hydraulic forging device. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape, and size. Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, because the complete metal flow lines are preserved, the mechanical properties of the forging are generally better than those of castings of the same material.

[0003] In the prior art, the traditional hydraulic forging device generally clamps the high-temperature rod-shaped metal blank between the forging bases that can be opened and closed. After the two forging bases are locked, the forging die barrel is controlled by the hydraulic cylinder to gradually descend until the high-temperature rod-shaped metal blank is covered. Then, the forging deformation of the top of the high-temperature rod-shaped metal blank inside the forging die barrel is achieved by the extrusion of the hydraulic cylinder. After the forging is completed, the forging die barrel is controlled by the hydraulic cylinder to move up and away from the forging base. Finally, the forging base is opened to take out the completed forging.

[0004] Although the above hydraulic forging device can meet the forging needs of metal billets, its forging demoulding is completely achieved by clamping pliers, which is not conducive to the high efficiency of forging demoulding during the entire forging process. At the same time, the traditional hydraulic forging device does not effectively reduce the impact of high-temperature heat conduction on hydraulic equipment. To this end, we provide a hydraulic forging device to solve the above problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For specific embodiment 1, please refer to Figure 1-12The present invention is a hydraulic forging device, comprising a forging conveying mechanism 1, a forging demoulding mechanism 2 is rotatably mounted on one side of the forging conveying mechanism 1, and the forging conveying mechanism 1 is installed inside a forging mechanism 3; wherein the forging conveying mechanism 1 comprises a forging bearing assembly 4, a forging conveying assembly 6 and a transmission assembly 7; a supporting hydraulic cylinder 5 is installed below the forging bearing assembly 4, and a supporting seat is connected to the output end of the supporting hydraulic cylinder 5, and the supporting seat is arranged directly below the forging station; the forging conveying assembly 6 is slidably mounted on the top of the forging bearing assembly 4, and the forging conveying assembly 6 comprises a rotatably mounted forging base 601, and a positioning pipe 60 is fixed to the bottom of the forging base 601 2; the transmission assembly 7 is rotatably installed on the top of the forging bearing assembly 4, and the transmission assembly 7 is meshed with the corresponding forging conveying assembly 6; the forging demolding mechanism 2 includes a U-shaped demolding frame 201, and a heat-insulating limit seat 202 is slidably arranged on the inner side of the U-shaped demolding frame 201, and a pushing demolding member 203 that moves synchronously with the heat-insulating limit seat 202 is arranged on the outer side of the U-shaped demolding frame 201; the forging mechanism 3 includes a driving tube 301 and a forging die barrel 302, and a hydraulic forging seat is arranged inside the forging die barrel 302. When the forging die barrel 302 moves down and fits on the top of the forging base 601, the downward driving tube 301 drives the forging base 601 to move to the forging station.

[0034] In this embodiment of the present invention, the forging mechanism 3 also includes a forging frame 303, and a vertical lifting platform 304 is slidably arranged inside the forging frame 303. The driving tube 301 and the forging die barrel 302 are both fixedly installed at the bottom of the vertical lifting platform 304. A support ring is fixedly arranged inside the forging die barrel 302, and a hydraulic forging seat is fitted at the bottom of the support ring. A U-shaped fixed platform 305 is fixedly installed at the bottom of the forging frame 303. The output end of the forging hydraulic cylinder 306 installed on the top of the forging frame 303 extends to the inside of the forging die barrel 302 and is fixedly connected to the hydraulic forging seat. By arranging a support ring inside the forging die barrel 302 and making it abut against the top of the hydraulic forging seat, the entire vertical lifting platform 304 is supported under the action of the forging hydraulic cylinder 306, and the up and down movement of the vertical lifting platform 304 is also controlled by the forging hydraulic cylinder 306.

[0035] In this embodiment of the present invention, the present invention also includes a power control mechanism 8; wherein, the power control mechanism 8 includes a power control frame 801 fixedly mounted on the top of the U-shaped fixed platform 305, the supporting hydraulic cylinder 5 is mounted on the bottom of the power control frame 801, a vertical mounting frame 802 is mounted on one side of the power control frame 801, the vertical mounting frame 802 is fixedly connected to the forging frame 303 through a support frame, a demolding control motor 803 is mounted on one side of the vertical mounting frame 802, the output end of the demolding control motor 803 is fixedly connected to the U-shaped demolding frame 201, the U-shaped demolding frame 201 is rotatably connected to the vertical mounting frame 802, a guide frame 804 is fixedly arranged on one side of the power control frame 801 close to the vertical mounting frame 802, and a first guide channel 805 is opened on the top of the guide frame 804.

[0036] The forging demoulding mechanism 2 also includes a demoulding hydraulic cylinder 204 installed on the U-shaped demoulding frame 201, the output end of the demoulding hydraulic cylinder 204 is fixedly connected to the heat insulation limit seat 202, and a demoulding control shaft 205 that slides through the U-shaped demoulding frame 201 is fixed on the surface of the heat insulation limit seat 202. A linkage part 206 is fixedly installed at the end of the demoulding control shaft 205, and a push demoulding member 203 is fixedly connected to the linkage part 206. The push demoulding member 203 is adapted to the size of the positioning pipe 602; the rotation of the entire forging demoulding mechanism 2 is controlled by the demoulding control motor 803, the push demoulding member 203 is at the bottom position, and the demoulding hydraulic cylinder 204 is at the top position (such as Figure 8 as shown).

[0037] In this embodiment of the present invention, the forging bearing assembly 4 includes a forging bearing platform 401 fitted on the top of the power control frame 801, a horizontal guide rod 402 is fixedly arranged on one side of the forging bearing platform 401, and the other side of the forging bearing platform 401 is fitted with the guide frame 804. A second guide channel 403 corresponding to the horizontal guide rod 402 is opened on the top of the forging bearing platform 401, and the first guide channel 805 and the second guide channel 403 are both adapted to the size of the positioning pipe 602. When the forging conveying assembly 6 is controlled to move horizontally in a direction away from the forging demolding mechanism 2, The positioning pipe 602 on the forging base 601 slides into the first guide channel 805 and slides along it into the second guide channel 403, and then continues to slide along the second guide channel 403 until the positioning pipe 602 rests on the end of the second guide channel 403. At this time, the forging base 601 is just on the forging station. The supporting seat is then controlled by the supporting hydraulic cylinder 5 to move upward until the supporting seat enters the specified position inside the positioning pipe 602. After the heated high-temperature rod-shaped metal billet is placed upright on the supporting seat in the positioning pipe 602, the forging process can be carried out.

[0038] In this embodiment of the present invention, the forging conveying assembly 6 also includes a forging conveying seat 603 that is fitted on the top of the forging bearing platform 401. The forging conveying seat 603 is slidably sleeved on the corresponding horizontal guide rod 402. A horizontal gear seat 604 is fixedly installed on one side of the forging conveying seat 603. The forging base 601 is rotatably installed on the side of the forging conveying seat 603 away from the horizontal guide rod 402 (specifically, the forging base 601 and the forging conveying seat 603 are tightly rotatably connected to ensure that the forging base 601 does not rotate when no external force is applied). In the initial state, the forging base 601 is away from the forging station, and its position is as shown in FIG. Figure 4 shown.

[0039] The transmission assembly 7 includes a support shaft rotatably mounted on the top of the forging bearing platform 401, a transmission gear 701 meshing with the corresponding horizontal gear seat 604 is fixedly mounted on the side surface of the support shaft, a vertical transmission column 702 is fixedly mounted on the top of the support shaft, and a first groove 703, a spiral groove 704 and a second groove 705 are respectively opened on the side surface of the vertical transmission column 702, and the spiral groove 704 is connected to the first groove 703 and the second groove 705 on the upper and lower sides thereof. A driving part adapted to the first groove 703, the spiral groove 704 and the second groove 705 is fixed. When the driving tube 301 is controlled to move downward and sleeved on the vertical transmission column 702, the driving part enters the first groove 703 and slides downward (the driving part will not cause the vertical transmission column 702 to rotate during the sliding process along the first groove 703). After the driving part enters the spiral groove 704 from the first groove 703, it starts to drive the vertical transmission column 702 to rotate clockwise (such as Figure 4 As shown in the figure, under the meshing action of the transmission gear 701 and the horizontal gear seat 604, the entire forging conveying assembly 6 is driven to move horizontally in the direction away from the forging demolding mechanism 2. When the positioning pipe 602 just abuts against the end of the second guide channel 403 (that is, it is at the forging station), the driving part just enters the second groove 705 from the spiral groove 704, and then controls the supporting seat to move upward through the supporting hydraulic cylinder 5 until the supporting seat enters the specified position inside the positioning pipe 602. After the heated high-temperature rod-shaped metal billet is placed upright on the supporting seat in the positioning pipe 602, the driving pipe 301 is continuously controlled to move downward. The driving part continues to slide downward along the second groove 705 without causing the vertical transmission column 702 to rotate until the driving part abuts against the bottom of the second groove 705. At this time, the bottom of the forging die barrel 302 just abuts against the top of the corresponding forging base 601, and the high-temperature rod-shaped metal billet is inside the forging die barrel 302.

[0040] Next, the hydraulic forging seat is controlled by the forging hydraulic cylinder 306 to move downward along the forging die barrel 302, and the high-temperature rod-shaped metal blank in the forging die barrel 302 is extruded and forged by the downwardly moved hydraulic forging seat to be deformed into a casting of a desired shape. After the forging is completed, the hydraulic forging seat is controlled by the forging hydraulic cylinder 306 to move upward until it abuts against the bottom of the support ring. As the hydraulic forging seat continues to move upward, the driving rotating tube 301 and the forging die barrel 302 can be synchronously moved upward until the driving rotating tube 301 and the forging die barrel 302 return to their initial positions. During the upward movement of the forging die barrel 302 and the forging die barrel 302, the driving portion moves along the second groove 705, the spiral groove 704 and the first groove 703 in sequence, driving the vertical transmission column 702 to rotate counterclockwise, and the entire forging conveying assembly 6 is driven back to the initial position under the meshing action of the transmission gear 701 and the horizontal gear seat 604. At this time, the forging base 601 moves between the U-shaped demoulding frame 201 and the heat-insulating limit seat 202 (that is, the bottom of the forging base 601 carrying the casting is supported by the U-shaped demoulding frame 201, and the top of the casting is limited by the heat-insulating limit seat 202).

[0041] Then, the demoulding control motor 803 is used to control the U-shaped demoulding frame 201 to rotate 180 degrees, so that the U-shaped demoulding frame 201 is turned over. At this time, the demoulding hydraulic cylinder 204 is at the lowest position, and the pushing demoulding member 203 is at the highest position. Then, the demoulding hydraulic cylinder 204 controls the heat insulation limit seat 202 to move downward, and the pushing demoulding member 203 that moves downward synchronously with the heat insulation limit seat 202 gradually enters the interior of the positioning pipe 602. Under the action of the pushing demoulding member 203, the casting in the positioning pipe 602 is pushed out and falls into the groove on the heat insulation limit seat 202. After the forging base 601 is completely separated from the forging base 601 and supported on the heat-insulating limit seat 202, it can be removed, and then the heat-insulating limit seat 202 and the push-pushing demolding member 203 are controlled by the demolding hydraulic cylinder 204 to return to the initial position, and the U-shaped demolding frame 201 is controlled to rotate 180 degrees again by the demolding control motor 803, so that the U-shaped demolding frame 201 returns to the initial position, that is, the demolding hydraulic cylinder 204 is at the uppermost position, and the push-pushing demolding member 203 is at the lowermost position. At this time, the forging base 601 and the positioning pipe 602 on the forging conveying assembly 6 return to the initial state (that is, Figure 4 In the state shown, the forging base 601 is arranged at the top), the forging process of the high-temperature rod-shaped metal blank can be continuously realized in the subsequent control method similar to the above.

[0042] Specific embodiment 2, on the basis of specific embodiment 1, a limit channel 806 is opened on the top of the power control frame 801, a power control screw 807 is rotatably installed inside the power control frame 801, the power control screw 807 is connected to the output end of a power motor 808 installed on the power control frame 801, and a moving seat 404 that slides with the limit channel 806 is fixedly arranged at the bottom of the forging support platform 401, the moving seat 404 is sleeved on the power control screw 807 and the two are threadedly matched. Through this structural design, the horizontal reciprocating motion of the entire forging conveying mechanism 1 can be realized through the rotation of the power control screw 807.

[0043] An air supply box 809 is installed on the side of the vertical mounting frame 802 away from the U-shaped demoulding frame 201, and a first air duct 810 is connected to one side of the air supply box 809, and a second air duct 811 is connected to the end of the first air duct 810, and one end of the second air duct 811 is connected to a first air outlet 812 adapted to the position of the supporting hydraulic cylinder 5, and the other end of the second air duct 811 is connected to a second air outlet 813, and the side surface of the second air duct 811 is connected to a third air outlet 814, and a first solenoid valve 815 located between the first air outlet 812 and the third air outlet 814 is installed on the second air duct 811, a second solenoid valve 816 is installed on the second air outlet 813, and a third solenoid valve 817 is installed on the third air outlet 814.

[0044] like Figure 1 and Figure 4 As shown, in the initial state, the forging conveying assembly 6 is symmetrically arranged on the left and right sides of the guide frame 804, and the forging die barrel 302 is arranged in the middle position of the two forging conveying assemblies 6 (that is, the forging die barrel 302 is directly above the forging station), and the power motor 808 is started to control the power control screw 807 to rotate forward. Under the action of the threaded cooperation between the power control screw 807 and the movable seat 404, the entire forging conveying mechanism 1 is driven to move horizontally to the right until the forging base 601 on the left forging conveying assembly 6 moves to the position of the U-shaped demoulding frame 201 (the forging base 601 is supported by the U-shaped demoulding frame 201). At this time, the positioning pipe 602 is just aligned with the first guide frame 201. Toward channel 805, and the second guide channel 403 is also just aligned with the first guide channel 805, and then the forging and demolding processing of the high-temperature rod-shaped metal billet can be realized according to the control method in the specific embodiment one. After completing the downward forging and controlling the driving tube 301 and the forging die barrel 302 to move up and reset, the controller opens the first solenoid valve 815 and starts the fan on the air supply box 809, so that the air flow enters the first air outlet part 812 along the first air duct 810 and the second air duct 811 in turn, and the air flow discharged through the first air outlet part 812 dissipates the heat of the supporting hydraulic cylinder 5, so as to reduce the influence of high-temperature heat conduction on the supporting hydraulic cylinder 5 during the forging process.

[0045] When the forging base 601 on the forging conveying assembly 6 on the left side moves to the U-shaped demolding frame 201 along the second guide channel 403 and the first guide channel 805, the power control screw 807 is controlled by the power motor 808 to rotate in the opposite direction. Under the action of the threaded cooperation between the power control screw 807 and the moving seat 404, the entire forging conveying mechanism 1 is driven to move horizontally to the left side until the forging base 601 on the forging conveying assembly 6 on the right side moves to the position of the U-shaped demolding frame 201 (the forging base 601 is supported by the U-shaped demolding frame 201). At this time, the positioning pipe 602 is just aligned with the first guide channel 805, and the second guide channel 403 is also just aligned with the positioning pipe 602. The first guide channel 805 is aligned with the positioning pipe 602 on the left forging and conveying assembly 6, and then the forging and demolding processing of the high-temperature rod-shaped metal billet can be realized according to the control method in the specific embodiment one.

The air flow discharged through the third air outlet 814 dissipates the heat to the positioning pipe 602 on the left forging and conveying assembly 6, so as to further reduce the influence of high-temperature heat conduction on the supporting hydraulic cylinder 5.

[0046] When the forging base 601 on the right forging conveying assembly 6 moves along the second guide channel 403 and the first guide channel 805 to the U-shaped demolding frame 201, the power control screw 807 is controlled by the power motor 808 to rotate forward again, and the power control screw 807 and the threaded cooperation of the moving seat 404 drive the entire forging conveying mechanism 1 to move horizontally to the right until the forging base 601 on the left forging conveying assembly 6 moves to the position of the U-shaped demolding frame 201 (the forging base 601 is supported by the U-shaped demolding frame 201). At this time, the positioning pipe 602 is just aligned with the first guide channel 805, and the second guide channel 403 is also just aligned with the first guide channel 805. The positioning pipe 602 on the forging and conveying assembly 6 is just aligned with the second air outlet 813, and then the forging and demolding processing of the high-temperature rod-shaped metal billet can be realized according to the control method in the specific embodiment one. In this process, the controller only opens the second solenoid valve 816 and starts the fan on the air supply box 809, so that the air flow enters the second air outlet 813 along the first air duct 810 and the second air duct 811 in turn. The air flow discharged through the second air outlet 813 dissipates the heat of the positioning pipe 602 on the forging and conveying assembly 6 on the right side, so as to further reduce the influence of high-temperature heat conduction on the supporting hydraulic cylinder 5. Subsequently, the forging processing of the high-temperature rod-shaped metal billet can be continuously realized according to the same control method as mentioned above.
