Description

Technical Field

[0001] The present invention relates to the technical field of rotary continuous forging platforms, and particularly to a rotary continuous forging platform and a forging process. Background Art

[0002] Continuous forging utilizes special continuous forging equipment to feed metal materials heated to a certain temperature into a forging machine through a continuous feeding device for forging. During the forging process, the metal materials are subjected to continuous pressure between the upper and lower dies of the forging machine, undergo plastic deformation, and finally obtain forgings with the required shape and size.

[0003] For example, the Chinese invention patent document with the publication number CN116921604B discloses a die for continuous forging of a stepped shaft, including a base, a turntable, a die, a driving device, a limiting device, a die closing device, a third telescopic rod, and a feeding device. Among them, the turntable is movably installed on the base, the driving device, the limiting device, the die closing device, the third telescopic rod, and the feeding device are fixedly installed at corresponding positions on the base, the die is fixed on the turntable by bolts, the driving device can cooperate with the turntable, the limiting device can cooperate with the die to limit the movement of the die, the position of the die closing device corresponds to the die, the position of the third telescopic rod corresponds to the die, and the position of the feeding device corresponds to the forming cavity of the die.

[0004] Although the above patent realizes low-cost and high-efficiency production, there are still the following deficiencies in actual use: Since the metal materials need to be heated to a certain temperature before forging, during the forging process, a certain amount of scale will be generated on the surface of the metal materials. These scales will remain in the forging die after forging, and each time it is necessary to manually clean the remaining scales, which is time-consuming and laborious; moreover, the connection between the workpiece after forging and the die is relatively tight, and it is difficult to demold the workpiece.

[0020] The vertical frame includes a vertical rod, a strip-shaped groove opened on the side surface of the vertical rod facing the protruding member, a support rod, a pin shaft, a spring piece and a limit block;

[0021] The top end of the support rod is hinged inside the strip-shaped groove through the pin shaft, and the bottom end of the support rod protrudes outside the notch of the strip-shaped groove through the spring piece;

[0022] The limit block is fixed to the top end of the support rod and is used to limit the maximum inclination angle of the support rod.

[0023] Preferably, the driving member includes a telescopic cylinder and a connecting rod. The bottom end of the telescopic cylinder is installed on the inner bottom surface of the recess, and the connecting rod is fixedly connected between the vertical rod and the piston rod of the telescopic cylinder.

[0024] Preferably, there are two vertical rods, and each vertical rod is correspondingly provided with a support rod, and a cross rod is fixed between the two vertical rods.

[0034] 1. By setting a base with a recessed part, and cooperating with the hinge device and the driving device, the lower die will rotate and fall into the recessed part under its own gravity when it rotates above the recessed part. Further, by splitting the lower die into two parts, namely the first lower half die and the second lower half die connected by hinges, the forged blank on the lower die falling into the recessed part is easier to fall off. Then, in combination with the purging device, high-pressure gas is used to purge the first lower half die and the second lower half die, cleaning the scale inside the first lower half die and the second lower half die while reducing the temperature of the first lower half die and the second lower half die, eliminating the time-consuming and laborious problem of manual cleaning of scale.

[0035] 2. By means of the lifting device and the arc-shaped rod provided in the present invention, multiple jitters of the first lower half mold and the second lower half mold can be achieved, thereby changing the relative angle between the first lower half mold and the second lower half mold and the high-pressure gas blown by the purging device, so as to more thoroughly purge and remove the scale.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figure 1 - Figure 9 , the present invention provides a technical solution:

[0048] A rotary continuous forging table, comprising a base 1, a mold 2, a hinge device 3, a driving device 4, a purging device 5, a guiding block 6, a lifting device 7 and an arc-shaped rod 8. The specific structures of these eight components and the relationships between them will be described in detail below.

[0049] As Figure 1 , Figure 5 shown, the top surface 12 of the base 1 has a recessed portion 11 that partially depresses downward, and the base 1 is integrally circular ring-shaped; the recessed portion 11 is used for the demolding operation after the blank forging is completed and for cleaning the scale peeled off from the blank during the forging process.

[0050] The mold 2 is used for forging a blank heated to a certain temperature so that the blank is forged into a predetermined shape. The mold 2 includes a plurality of lower molds 21 and an upper mold 22. Among them, the upper mold 22 can move up and down in the vertical direction (the upper mold 22 can be driven by components such as a hydraulic cylinder to move up and down, which is the prior art and will not be elaborated here). The plurality of lower molds 21 are rotatably arranged on the top surface 12 of the base 1, so that the plurality of lower molds 21 can successively rotate to the directly below of the upper mold 22 and above the recessed portion 11. A positioning hole 213 is opened on the upper surface of the lower mold 21, and a positioning pin 221 adapted to the positioning hole 213 is fixed at the bottom of the upper mold 22.

[0051] Furthermore, the lower mold 21 includes a first lower half mold 211 and a second lower half mold 212 that are hinged. The first lower half mold 211 and the second lower half mold 212 are arranged in sequence along the radial direction of the base 1. The hinge axis of the first lower half mold 211 and the second lower half mold 212 is located inside the lower surface of the lower mold 21. Specifically, when the lower surface of the lower mold 21 contacts the top surface 12, the lower surface of the lower mold 21 is a horizontal plane. At this time, the hinge axis of the first lower half mold 211 and the second lower half mold 212 is located inside the lower surface of the lower mold 21, ensuring that the first lower half mold 211 and the second lower half mold 212 can rotate around this hinge axis; a horizontally arranged arc-shaped rod 8 is fixed inside the recessed portion 11, and the first lower half mold 211 and the second lower half mold 212 that fall inside the recessed portion 11 are supported and opened by the arc-shaped rod 8; specifically, as Figure 6 - Figure 8The state of the first lower die half 211 and the second lower die half 212 located inside the recess 11 is shown. At this time, the first lower die half 211 and the second lower die half 212 are kept in an open state under the support and limit action of the arc-shaped rod 8. In this state, the forged blank in the first lower die half 211 and the second lower die half 212 is more easily demolded, and at the same time, the first lower die half 211 and the second lower die half 212 in this state are also more easily cleaned of scale.

[0052] The driving device 4 is used to drive the lower die 21 to rotate. Specifically, in this embodiment, the driving device 4 drives the lower die 21 to rotate counterclockwise, and the lower die 21 is hinged to the driving device 4 through the hinge device 3; further, the driving device 4 includes a gear ring 41, a gear 42 meshing with the gear ring 41, and a motor for driving the gear 42 to rotate. The motor here can be a servo motor or a stepping motor. The gear ring 41 is slidably connected to the base 1 through structures such as an annular guide rail; the first lower die half 211 is hingedly connected to the gear ring 41 through the hinge device 3.

[0053] The hinge device 3 rotates and falls into the inside of the recess 11 by its own gravity when the lower die 21 rotates above the recess 11; specifically, as Figure 2 and Figure 4 shown, the hinge device 3 includes a first fixing block 31, a hinge shaft 32, and a second fixing block 33. Among them, the hinge shaft 32 is fixedly connected to the first lower die half 211 through the first fixing block 31, the second fixing block 33 is rotatably sleeved on the hinge shaft 32 through a bearing, and the second fixing block 33 is fixedly connected to the gear ring 41.

[0054] The purging device 5 is arranged in the recess 11, and the purging port of the purging device 5 faces the cavity of the lower die 21. In this way, the cavity of the lower die 21 can be purged with high-pressure gas to remove the scale peeled off from the blank during forging inside it, and at the same time, the temperature of the lower die 21 is reduced to prepare for the next forging operation; the purging device 5 includes a manifold 52 and nozzles 53 fixedly installed on the side of the manifold 52. The nozzles 53 are communicated with a high-pressure gas source through air pipes 51.

[0055] The guiding block 6 is arranged inside the recess 11, and a spiral surface 61 is provided at its top. The low end 62 of the spiral surface 61 is lower than the height of the lowest point of the lower die 21 located inside the recess 11, and the high end 63 of the spiral surface 61 is connected to the top surface 12 of the base 1. Here, the connection means that the height of the high end 63 is the same as the height of the top surface 12 of the base 1, and the two are fixedly connected, so that the lower die 21 can be restored to the state of contacting the top surface 12 of the base 1 through the spiral surface 61.

[0056] The basic working principle of the above solution is as follows: First, place the heated blank to be forged into a suitable one of the multiple lower dies 21 (taking four lower dies 21 as an example as shown in the figure, and starting from the lower die 21 directly below the upper die 22 for a counterclockwise description. Among them, the lower die 21 directly below the upper die 22 is at the forging station, the next lower die 21 in the counterclockwise direction is at the demolding and cleaning station, the next lower die 21 after the demolding and cleaning station is at the restoration station, and the next lower die 21 after the restoration station is at the loading station. The heated blank to be forged is placed into the lower die 21 at this loading station). Then, start the motor of the driving device 4 to drive the gear 42 to rotate, and the gear 42 then drives the ring gear 41 to rotate, so that the ring gear 41 drives the multiple lower dies 21 to rotate. Among them, the lower die 21 at the loading station and the blank to be forged on it will be rotationally transported directly below the upper die 22. Then, turn off the driving device 4, and then use the cooperation of the lower die 21 and the upper die 22 to complete the forging operation on the blank. After forging is completed, start the driving device 4 again to move the forged blank and the lower die 21 towards the demolding and cleaning station. During this process, the lower die 21 will enter the recess 11 due to the existence of the hinge device 3, and under the limiting action of the arc-shaped rod 8, the first lower half die 211 and the second lower half die 212 that make up the lower die 21 will open. At this time, the forged blank in the lower die 21 will fall off from the lower die 21 due to the opening of the first lower half die 211 and the second lower half die 212, completing demolding. When the lower die 21 completely moves to the demolding and cleaning station, the purging device 5 uses high-pressure gas to purge the first lower half die 211 and the second lower half die 212, cleaning the scale inside the first lower half die 211 and the second lower half die 212 while reducing the temperature of the first lower half die 211 and the second lower half die 212. Then, with the next drive of the driving device 4 and in cooperation with the guiding block 6, the first lower half die 211 and the second lower half die 212 can be restored to a horizontal state, that is, the restoration station.

[0057] In the above solution, by setting the base 1 with the recess 11, and then cooperating with the hinge device 3 and the driving device 4, when the lower die 21 rotates above the recess 11, it will rotate and fall into the recess 11 under its own gravity. Further, by splitting the lower die 21 into two parts, the first lower half die 211 and the second lower half die 212 that are hinged together, the forged blank on the lower die 21 falling into the recess 11 is more likely to fall off. Then, combined with the purging device 5 using high-pressure gas to purge the first lower half die 211 and the second lower half die 212, the scale inside the first lower half die 211 and the second lower half die 212 is cleaned while reducing the temperature of the first lower half die 211 and the second lower half die 212, eliminating the time-consuming and laborious problem of manual scale cleaning.

[0058] To completely remove the scale on the lower die 21, a protruding member 34 is fixed on the circumferential surface of the hinge shaft 32; and the forging table further includes a lifting device 7 disposed inside the recess 11. The lifting device 7 includes a vertical frame 73 and a driving member for driving the vertical frame 73 to lift between the protruding member 34 and the gear ring 41; the vertical frame 73 includes a vertical rod 731, a strip-shaped groove 733 opened on the side surface of the vertical rod 731 facing the protruding member 34, a support rod 734, a pin shaft 735, a spring piece 736 and a limit block 737; the top end of the support rod 734 is hinged inside the strip-shaped groove 733 through the pin shaft 735, and the bottom end of the support rod 734 protrudes outside the notch of the strip-shaped groove 733 through the spring piece 736; the limit block 737 is fixed at the top end of the support rod 734 for limiting the maximum inclination angle of the support rod 734.

[0059] Furthermore, the driving member includes a telescopic cylinder 71 and a connecting rod 72. The telescopic cylinder 71 can be a hydraulic cylinder or the like. Of course, the driving member can also be fixedly connected to the upper die 22, so that the vertical frame 73 rises and falls together with the upper die 22. The bottom end of the telescopic cylinder 71 is installed on the inner bottom surface of the recess 11, and the connecting rod 72 is fixedly connected between the vertical rod 731 and the piston rod of the telescopic cylinder 71.

[0060] In this embodiment, there are two vertical rods 731, and each vertical rod 731 is correspondingly provided with a support rod 734, and a cross bar 732 is fixed between the two vertical rods 731.

[0061] The working principle of the lifting device 7 cooperating with the protruding member 34 is: under normal conditions, such as Figure 8 and Figure 9As shown, the bottom end of the support rod 734 protrudes from the notch of the strip-shaped groove 733 under the support of the spring piece 736 and contacts the upper surface of the protruding piece 34. Start the telescopic cylinder 71, and drive the vertical frame 73 to move downward by using the connecting rod 72. At this time, since the bottom end of the support rod 734 presses against the upper surface of the protruding piece 34, the downward movement of the support rod 734 will push the protruding piece 34 and the hinge shaft 32 to rotate around the axis of the hinge shaft 32 itself. Also, since the hinge shaft 32 is fixedly connected to the first lower mold half 211, the first lower mold half 211 will rotate together with the hinge shaft 32, causing the first lower mold half 211 and the second lower mold half 212 to separate from the arc-shaped rod 8. When the protruding piece 34 rotates to a predetermined angle, the support rod 734 separates from the protruding piece 34. At this time, the support rod 734 continues to move downward, but the protruding piece 34 will rotate in the reverse direction due to the gravity of the first lower mold half 211 and the second lower mold half 212 until the first lower mold half 211 and the second lower mold half 212 rest on the arc-shaped rod 8 again, thereby forming vibrations for shaking off the scale. At the same time, since the angles of the first lower mold half 211 and the second lower mold half 212 change during the process of separating from the arc-shaped rod 8, and the angle of the high-pressure gas ejected by the purging device 5 remains unchanged, the high-pressure gas ejected by the purging device 5 will purge the scale remaining on the first lower mold half 211 and the second lower mold half 212 from different angles, making it easier for the high-pressure gas to enter the gap between the scale and the first lower mold half 211 and the second lower mold half 212, and then enabling the scale to fall off more thoroughly from the first lower mold half 211 and the second lower mold half 212. In this embodiment, multiple support rods 734 can be provided on the same vertical rod 731. When the vertical frame 73 moves downward to the lowest point and then is driven to move upward by the telescopic cylinder 71, the protruding piece 34 will play a role in squeezing the support rod 734 to retract it into the strip-shaped groove 733.

[0062] A forging process, the forging process is based on the above-mentioned rotary continuous forging table, and includes the following steps:

[0063] S1. Place the blank to be forged on the lower mold 21;

[0064] S2. Use the driving device 4 to drive the lower mold 21 to rotate a certain angle, so that the lower mold 21 and the blank rotate and move to directly below the upper mold 22;

[0065] S3. Drive the upper mold 22 and the lower mold 21 to close and then open the mold to realize forging of the blank;

[0066] S4. Continue to drive the lower die 21 and the forged blank to rotate by the driving device 4, so that the lower die 21 and the forged blank fall into the recess 11, and start the purging device 5. On the one hand, the arc-shaped rod 8 will change the angle between the first lower half die 211 and the second lower half die 212 which are hinged, and the forged blank will be demoulded; on the other hand, the purging device 5 can purge and remove the scale residues in the lower die 21 and reduce the temperature of the lower die 21;

[0067] S5. Continue to drive the first lower half die 211 and the second lower half die 212 to rotate by the driving device 4, so that the first lower half die 211 and the second lower half die 212 move back to the top surface 12 of the base 1 under the action of the spiral surface 61 of the guiding block 6, and wait for the next forging.

[0068] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
