Description

Technical Field

[0001] The present application relates to the technical field of forging stacking and storage, and in particular to a forging stacking and storage device. Background Art

In addition, the highest point of the pad conveying mechanism is lower than the top of the pad, when the forging ring is hoisted, the collision between the forging ring and the pad conveying mechanism when the forging ring shakes is reduced, and by setting an auxiliary support mechanism, more support positions can be provided for the forging ring.

[0003] However, in the process of stacking forgings, only four pads are placed between the upper and lower forgings to form spacing and support, which cannot ensure the stability between the upper and lower forgings.

Once collapsed, the forgings may be easily damaged and unpredictable risks may be added to the working environment. Summary of the invention

[0008] The hydraulic oil drives the top clamping assembly and the bottom clamping assembly to synchronously cause radial displacement through the axial displacement of the active piston assembly.

[0011] Preferably, one end of the bottom slideway facing the axis of the support tube is connected to a bottom guide channel, and the bottom guide channel is axially arranged and connected to the inner cavity of the support tube.

[0012] Preferably, the top bearing assembly includes: an axial sliding rod and a top bearing plate, the axial sliding rod is sealingly slidably inserted in the support tube; the top bearing plate is fixedly connected to one end of the axial sliding rod extending out of the support tube.

[0013] Preferably, the active piston assembly includes: a fixed piston, a movable piston and an elastic member, the fixed piston is fixedly sleeved on the axial sliding rod and sealingly slides on the inner wall of the support tube; the movable piston is slidably sleeved on the axial sliding rod and slidably connected to the inner wall of the support tube; the elastic member is sleeved on the axial sliding rod, and both ends of the elastic member are respectively fixed to the fixed piston and the movable piston.

[0014] Preferably, the top clamping assembly includes: a top sliding rod and a top column, a plurality of the top sliding rods are evenly arranged along the radial direction of the support tube, and are sealingly slidably inserted into the top of the side wall of the support tube; a plurality of the top columns are respectively fixed to one end of the plurality of top sliding rods extending out of the support tube.

That is, the heavier the load within a certain range, the more stable the clamping of the annular workpiece. On the contrary, when the load is smaller (in the process of removing the annular workpiece from the top of the support cylinder), the clamping force is smaller, so as to avoid the top clamping assembly maintaining a constant clamping force, which makes it difficult to remove the annular workpiece;

[0019] 3. The support column can be used to limit the axial displacement stroke of the top load-bearing component in the support tube, and provide support for the top load-bearing component to prevent the top load-bearing component from having an excessive axial downward stroke as the number of stacked layers of annular workpieces increases, causing the force transmitted by the hydraulic oil to the top clamping component and the bottom clamping component to exceed a predetermined range, thereby causing damage to the components inside the support tube. The limitation of the axial stroke of the top load-bearing component controls the clamping force of the top clamping component and the bottom clamping component, and limits the pressure value of the hydraulic oil inside the support tube.

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Embodiment 1, as Figure 1-Figure 14 As shown, a forging stacking storage device according to an embodiment of the present application includes a bearing base 2, and the bearing base 2 is used to bear a plurality of stacked annular workpieces 1.

[0040] It should be noted that, in the specific embodiments of the present application, relevant external devices can be adapted. For example, lifting devices are symmetrically arranged on both sides of the bearing base 2. Electric push rods are horizontally installed on the lifting devices. The telescopic ends of the electric push rods on the two lifting devices approach each other and point to each other. The telescopic ends of the electric push rods are horizontally installed with U-shaped frames. By driving the electric push rods through the lifting devices to change the height, and driving the U-shaped frames to approach or move away from each other through the electric push rods, it plays a centering role in the process of stacking the annular workpieces 1. At the same time, relevant robotic arms can also be adapted to clamp the support cylinder 31 in the embodiments of the present application and place it on the top of the stacked annular workpieces 1. Of course, specifically how to place the annular workpieces 1 and how to place the support cylinder 31 on the annular workpieces 1 are already very mature in the prior art and are also involved in the application documents cited in the present application, so they will not be elaborated here.

[0041] Specifically, as Figure 1 shown, a forging stacking and storage device according to an embodiment of the present application further includes a plurality of support mechanisms 3. The plurality of support mechanisms 3 are circumferentially and evenly arranged between two adjacent annular workpieces 1, and the plurality of support mechanisms 3 are staggeredly arranged between the plurality of stacked annular workpieces 1.

[0042] It should be noted that, circumferentially and evenly arranged on the same annular workpiece 1, it can play the effects of evenly bearing weight and stably supporting. Staggeredly placed between the plurality of stacked annular workpieces 1, it can also play the effects of evenly bearing and stably supporting.

[0043] As Figure 2-Figure 4 shown, the support mechanism 3 includes a support cylinder 31. A top bearing assembly 32 is axially and slidably inserted into the top of the support cylinder 31. It should be noted that, in the specific embodiments of the present application, the relationship between the top bearing assembly 32 and the support cylinder 31 is a sealed and slidable insertion relationship; a main piston assembly 33 is hermetically slid in the support cylinder 31. The main piston assembly 33 is fixedly sleeved on the top bearing assembly 32. It can be seen from this that a fixed connection is formed between the main piston assembly 33 and the top bearing assembly 32, and they are synchronously axially displaced inside the support cylinder 31. Top clamping assemblies 34 and bottom clamping assemblies 35 are respectively hermetically and slidably arranged at the top and bottom ends of the side wall of the support cylinder 31. A support column 36 is coaxially and fixedly connected to the inner bottom of the support cylinder 31.

[0044] It can be understood that, in the specific embodiments of the present application, the support column 36 and the top bearing assembly 32 are coaxial. The existence of the support column 36 limits the axial displacement stroke of the top bearing assembly 32 in the support cylinder 31 to a certain extent and plays a rigid support role for the top bearing assembly 32.

[0045] It should be noted that hydraulic oil is provided inside the support cylinder 31, and a plurality of oil circuits for the circulation of the hydraulic oil are circumferentially arranged on the cavity wall of the support cylinder 31. The oil circuit is arranged in an E-shape, and the lateral parts of the E-shaped oil circuits are connected to the interior of the support cylinder 31, and the oil circuits are respectively connected to the slideway where the top clamping assembly 34 is located and the slideway where the bottom clamping assembly 35 is located; the hydraulic oil is forced to flow in the E-shaped oil circuit through the axial displacement of the active piston assembly 33, thereby driving the top clamping assembly 34 and the bottom clamping assembly 35 to synchronously cause radial displacement.

[0046] In addition, a forging stacking storage device according to an embodiment of the present application also has the following additional technical features:

[0047] like Figure 5-Figure 7 As shown, the E-shaped oil circuit in the support cylinder 31 includes: an axial channel 311, a radial channel 312, a top slide 313 and a bottom slide 314. The axial channel 311 is axially arranged in the cavity wall of the support cylinder 31; the radial channel 312 is arranged at the bottom of the inner wall of the support cylinder 31, which connects the inner cavity of the support cylinder 31 and the axial channel 311. It should be noted that in the specific embodiment of the present application, the position of the radial channel 312 is arranged at the lower part of the inside of the support cylinder 31 to ensure that there is enough space above it for the displacement of the active piston assembly 33; the top slide 313 is arranged along the radial direction of the support cylinder 31, and is connected to the top end of the axial channel 311, and it is in sealing and sliding cooperation with the top clamping assembly 34; the bottom slide 314 is arranged along the radial direction of the support cylinder 31, and is connected to the bottom end of the axial channel 311, and it is in sealing and sliding cooperation with the bottom clamping assembly 35.

[0048] Furthermore, one end of the top slide 313 facing the axis of the support tube 31 is connected to a top guide channel 315 , and the top guide channel 315 is axially arranged and connected to the inner cavity of the support tube 31 .

[0049] Furthermore, one end of the bottom slideway 314 facing the axis of the support tube 31 is connected to a bottom guide channel 316 , and the bottom guide channel 316 is axially arranged and connected to the inner cavity of the support tube 31 .

[0050] It should be noted that the cross-sectional size of the top slide 313 and the bottom slide 314 is larger than the cross-sectional size of the top guide channel 315 and the bottom guide channel 316. It can be understood that Figure 4As shown, when the active piston assembly 33 moves downward, the hydraulic oil thereunder will be squeezed to flow into the radial channel 312 and the bottom guide channel 316 respectively. At this time, the top clamping assembly 34 will be subjected to a radial inward force, and the bottom clamping assembly 35 will be subjected to two forces, radial inward and radial outward. Due to the size of the hydraulic oil flow channel, the inward radial force on the bottom clamping assembly 35 is greater than the outward radial force. In this way, it is ensured that the top clamping assembly 34 and the bottom clamping assembly 35 can be displaced in the same direction.

[0051] like Figure 4 and Figure 5 As shown, the top bearing assembly 32 includes: an axial slide rod 321 and a top bearing plate 322. The axial slide rod 321 is sealingly slidably inserted into the support tube 31; the top bearing plate 322 is fixedly connected to one end of the axial slide rod 321 extending out of the support tube 31. It can be understood that when placing the support tube 31, the end with the top bearing plate 322 is facing upwards, and the top bearing plate 322 is used to support the annular workpiece 1 above it.

[0052] like Figure 4 and Figure 5 As shown, the active piston assembly 33 includes: a fixed piston 331, a movable piston 332 and an elastic member 333. The fixed piston 331 is fixedly sleeved on the axial slide rod 321 and seals and slides on the inner wall of the support tube 31; the movable piston 332 is slidably sleeved on the axial slide rod 321 and slidably connected to the inner wall of the support tube 31; the elastic member 333 is sleeved on the axial slide rod 321, and its two ends are respectively fixed to the fixed piston 331 and the movable piston 332. It should be noted that when the movable piston 332 is at the lowest point of its own stroke, the axial slide rod 321 still extends out of the bottom end of the movable piston 332 to prevent the movable piston 332 from detaching from the axial slide rod 321.

[0053] It can be understood that the presence of the elastic member 333 enables the active piston assembly 33 to have a certain elastic displacement. In this way, when the active piston assembly 33 is subjected to a force to undergo a downward axial displacement, the movable piston 332 itself will also be subjected to an equal amount of reaction force when applying pressure to the hydraulic oil on its bottom side. Therefore, the elastic member 333 will be compressed at this time, and the movable piston 332 will undergo a certain displacement toward the fixed piston 331. This design ensures that after the top bearing plate 322 receives the pressure applied by the annular workpiece 1, the pressure will not be directly transmitted to the hydraulic oil. The elastic member 333 consumes a certain amount of force and converts the force that should have been rigid into a flexible force, thereby protecting the force-bearing components to a certain extent.

[0054] like Figure 4 and Figure 5As shown, the top clamping assembly 34 includes: a top slide bar 341 and a top column 342. A plurality of top slide bars 341 are evenly arranged along the radial direction of the support tube 31, and are sealed and slidably inserted into the top of the side wall of the support tube 31; a plurality of top columns 342 are respectively fixed to one end of a plurality of top slide bars 341 extending out of the support tube 31; a plurality of top slide bars 341 respectively correspond to the top slide 313 one by one, and form a radially limited sealed sliding connection in the top slide 313.

[0055] Furthermore, the bottom clamping assembly 35 includes: a bottom slide rod 351 and a bottom column 352, wherein a plurality of bottom slide rods 351 are evenly arranged along the radial direction of the support tube 31, and are sealed and slidably inserted into the bottom of the side wall of the support tube 31; a plurality of bottom columns 352 are respectively fixed to one end of the plurality of bottom slide rods 351 extending out of the support tube 31; a plurality of bottom slide rods 351 respectively correspond one by one to the bottom slideway 314, and form a radially limited sealed sliding connection in the bottom slideway 314.

[0056] It should be noted that, in the specific embodiment of the present application, the ends of the top sliding rod 341 and the bottom sliding rod 351 inserted into the support tube 31 are both L-shaped. Figure 4 and Figure 5 As shown, the radial parts of the top slide bar 341 and the bottom slide bar 351 are respectively slidably connected to the corresponding top slide 313 and the bottom slide 314, and the parts are smaller than the cross-sectional size of the top slide 313 and the bottom slide 314. The inner ends of the top slide bar 341 and the bottom slide bar 351 (with axial protrusions) are sealed and slidably matched with the top slide 313 and the bottom slide 314, so that after the hydraulic oil enters the top slide 313 and the bottom slide 314, radial force is applied to the top slide bar 341 and the bottom slide bar 351.

[0057] It should be further explained that in the specific embodiment of the present application, the top column 342 and the bottom column 352 are arranged in a cylindrical shape to reduce damage to the side wall of the workpiece when clamping the annular workpiece 1. At the same time, the cylindrical design can reduce the contact area between the two, thereby facilitating the annular workpiece 1 to be detached from the support tube 31.

[0058] The following describes the use process of a forging stacking storage device according to an embodiment of the present application with reference to the accompanying drawings:

[0059] When in use, the annular workpieces 1 are coaxially (centered) placed one by one on the bearing base 2. The specific placement and how the annular workpieces 1 are transferred to the bearing base 2 are not described in detail here. In the specific embodiment of the present application, the bottom annular workpiece 1 is directly placed on the bearing base 2, and it is only necessary to keep the annular workpiece 1 and the bearing base 2 coaxial, and then on the upper end surface of the bottom annular workpiece 1, a plurality of support cylinders 31 are evenly placed in the circumferential direction. It should be noted here that one end of the top bearing plate 322 needs to be placed upward. If it is found during the placement process that the opening range of the top clamping assembly 34 and the bottom clamping assembly 35 is smaller than the width of the annular workpiece 1, the top bearing plate 322 can be directly pulled upward to allow the hydraulic oil therein to flow radially outward. The oil in the oil circuit flows outward, causing the top clamping assembly 34 and the bottom clamping assembly 35 to increase their opening range (of course, a spring can be added between the top bearing plate 322 and the support tube 31 so that the top bearing plate 322 is located at the top of its stroke in the initial state, that is, at this time, the top clamping assembly 34 and the bottom clamping assembly 35 are at their maximum opening range, and the top bearing plate 322 has an active reset function). After the support tube 31 is placed, the next annular workpiece 1 is stacked on this layer of support tube 31, that is, the second layer of annular workpiece 1 from bottom to top is placed on the top bearing plate 322 of the first layer of support tube 31. At this time, the top bearing plate 322 of this layer of support tube 31 is subjected to force and drives the axial slide rod 3 under the action of pressure. 21 and the fixed piston 331 fixed on the axial slide bar 321 undergo downward axial displacement. During this process, the hydraulic oil at the bottom side of the active piston assembly 33 will be squeezed into the axial channel 311 through the radial channel 312 due to its reduced volume, and will be diverted to the top slide 313 and the bottom slide 314, exerting an inward radial force on the top slide bar 341 and the bottom slide bar 351. It should be noted that at this time, the bottom slide bar 351 will also be exerted with an outward radial force on the bottom slide bar 351 because part of the hydraulic oil directly flows into the bottom guide channel 316. Since the oil passage here is small, the outward radial force here is smaller than the inward radial force, so it does not affect the inward radial position of the bottom slide bar 351 at this time. The top slide bar 341 moves downward, while the top slide bar 341, due to the downward displacement of the active piston assembly 33, a negative pressure will be formed above it, generating suction in the top slideway 313, and cooperating with the inward radial force exerted by the hydraulic oil near one end of the axial channel 311, it is more conducive to the inward displacement of the top slide bar 341. Therefore, under the drive of the hydraulic oil, the top clamping assembly 34 and the bottom clamping assembly 35 both undergo inward radial displacement and achieve a clamping effect on the annular workpiece 1 on both sides. At the same time, because the fixed piston 331 moves downward following the axial slide bar 321, the hydraulic oil at the bottom is under pressure and will exert the same magnitude of reverse force on the movable piston 332. In this way, the elastic member 333 between the movable piston 332 and the fixed piston 331 will be compressed.The rigid pressure transmitted by the axial slide bar 321 is converted into flexible pressure to avoid damage to the pressure-bearing parts inside the support tube 31. The axial displacement of the top load-bearing plate 322 is not stopped until the stroke of the top clamping assembly 34 and the bottom clamping assembly 35 is limited, or the axial slide bar 321 abuts against the support column 36, and then multiple support tubes 31 are placed on the upper end surface of the second layer of annular workpiece 1. It should be noted that the placement of this layer (second layer) of support tubes 31 is staggered with the support tubes 31 of the layer below it to balance the supporting capacity. In this way, one layer of annular workpiece 1 and one layer of support tube 31 are placed to achieve stacking of multiple annular workpieces 1. As the number of stacked layers of annular workpieces 1 increases, the multiple support tubes 31 at the bottom The top bearing plate 322 on the layer support cylinder 31 will be subjected to increasing pressure. If the axial slide bar 321 originally fixed to the top bearing plate 322 does not abut against the support column 36, then as the pressure gradually increases, the axial slide bar 321 will continue to move downward. In this process, the top clamping assembly 34 and the bottom clamping assembly 35 that originally clamped the inner and outer side walls of the annular workpiece 1 will not continue to move radially inward. Therefore, as the axial slide bar 321 continues to move downward, the hydraulic oil under the active piston assembly 33 will apply reverse pressure to the movable piston 332 due to the increase in pressure, forcing the movable piston 332 to continue to move toward the fixed piston 331, and the active piston assembly 332 is located at the bottom of the active piston assembly 331. The hydraulic oil above 33 will present negative pressure in the space inside it as the fixed piston 331 descends, exerting an upward pulling force on the fixed piston 331, which will offset the pressure on the top bearing plate 322 to a certain extent until the axial slide bar 321 abuts against the support column 36 to form a rigid support. At this time, the pressure value in the entire support cylinder 31 is constant, avoiding the pressure change in the support cylinder 31 beyond the range and causing damage to the pressure-bearing parts on the support cylinder 31. This design ensures that each layer of the stacked annular workpiece 1 can be fixed, ensuring the stability and safety of the annular workpiece 1 during stacking and storage, and avoiding the occurrence of tilting, sliding, collapse, etc. caused by transportation. When the annular workpiece 1 is removed from the support tube 31, the top bearing plate 322 on the topmost support tube 31 loses the pressure exerted by the annular workpiece 1, and the hydraulic oil therein loses the radial pressure on the top slide bar 341 and the bottom slide bar 351. Therefore, in the process of removing the annular workpiece 1, the top column 342 and the bottom column 352 will not maintain a continuous clamping force on the annular workpiece 1, and the structural design of the top column 342 and the bottom column 352 themselves further reduces the friction between the annular workpiece 1 and the top clamping assembly 34 and the bottom clamping assembly 35, making it easier to remove the annular workpiece 1. In this way, the annular workpiece 1 and the support tube 31 can be removed layer by layer from top to bottom.

[0060] In the related art, in this forging stacking storage device, as the number of stacked layers of the annular workpieces 1 increases, the pressure applied to the support cylinder 31 at the bottom becomes greater and greater, and the hydraulic oil in the support cylinder 31 is exerted on the top slide bar 341, the bottom slide bar 351 and the elastic member 333. The longer the storage time, the longer the top slide bar 341, the bottom slide bar 351 and the elastic member 333 are subjected to the force. Therefore, it is very easy for the components to be damaged due to long-term storage, and even leakage may occur.

[0061] According to some embodiments of the present application, Figure 2 , Figure 3 , Figure 8-Figure 10 As shown, a buffer mechanism 4 is provided inside the support cylinder 31, and the buffer mechanism 4 includes: a top buffer component 41 and a bottom buffer component 42, the top buffer component 41 is fixedly connected to the support cylinder 31, and is sealed and slidably matched with the axial slide rod 321, and is located on the top side of the active piston component 33; the bottom buffer component 42 is fixedly connected to the support cylinder 31, and is fixedly sleeved on the support column 36, and is located on the bottom side of the active piston component 33; the top buffer component 41 and the active piston component 33 are filled with compressed gas; the top buffer component 41 and the bottom buffer component 42 are both filled with compressed gas.

[0062] It should be noted that hydraulic oil is filled between the top slide bar 341 and the top upper buffer piston 414, and between the bottom slide bar 351 and the bottom lower buffer piston 425, so as to facilitate better force transmission.

[0063] Specifically, Figure 8-Figure 10 As shown, the top buffer assembly 41 includes: a top buffer shell 411, a top buffer inner shell 412, a top mounting plate 413, a top upper buffer piston 414 and a top lower buffer piston 415. The top buffer shell 411 is fixedly connected to the inner wall of the support cylinder 31; the top buffer inner shell 412 and the axial slide rod 321 are sealed and slidably matched; a plurality of top mounting plates 413 are symmetrically arranged on the top and bottom sides of the top buffer inner shell 412, and are evenly arranged along the circumference of the top buffer inner shell 412, and the two ends thereof are respectively fixedly connected to the top buffer shell 411 and the top buffer inner shell 412. It can be seen that the top buffer shell 41 1 and the top buffer inner shell 412 are fixedly connected (this place is preferably detachable and fixed to facilitate maintenance and replacement of its internal components). It can be further understood that the axial slide rod 321 is sealingly slidably inserted into the top buffer inner shell 412; the top upper buffer piston 414 is sealingly slidable between the top buffer outer shell 411 and the top buffer inner shell 412; the top lower buffer piston 415 is sealingly slidable between the top buffer outer shell 411 and the top buffer inner shell 412, and is located on the bottom side of the top upper buffer piston 414; the top upper buffer piston 414 and the top lower buffer piston 415 are filled with compressed gas.

[0064] It can be seen that the space between the top upper buffer piston 414 and the top lower buffer piston 415 , as well as the space between the top lower buffer piston 415 and the fixed piston 331 are filled with compressed gas.

[0065] Furthermore, the bottom buffer assembly 42 includes: a bottom buffer shell 421, a bottom buffer inner shell 422, a bottom mounting plate 423, a bottom upper buffer piston 424 and a bottom lower buffer piston 425. The bottom buffer shell 421 is fixedly connected to the inner wall of the support tube 31; the bottom buffer inner shell 422 is fixedly sleeved on the support column 36; a plurality of bottom mounting plates 423 are symmetrically arranged on the top and bottom sides of the bottom buffer inner shell 422, and are evenly arranged along the circumference of the bottom buffer inner shell 422, and their two ends are respectively fixedly connected to the bottom buffer shell 421 and the bottom buffer inner shell 422, thereby it can be known that a fixed connection is formed between the bottom buffer shell 421 and the bottom buffer inner shell 422; the bottom upper buffer piston 424 is sealed and slides between the bottom buffer shell 421 and the bottom buffer inner shell 422; it is sealed and slides between the bottom buffer shell 421 and the bottom buffer inner shell 422, and is located on the bottom side of the bottom upper buffer piston 424; the bottom upper buffer piston 424 and the bottom lower buffer piston 425 are filled with compressed gas.

[0066] Therefore, in actual use, when the top bearing plate 322 is forced to move downward, during this process, the hydraulic oil on the bottom side of the movable piston 332 will be forced to flow into the radial channel 312, and then will be divided and apply inward radial force to the top slide bar 341 and the bottom slide bar 351 respectively, and cause both to move radially inward. Firstly, when the top slide bar 341 moves inward, it will squeeze the hydraulic oil between it and the top buffer piston 414. The hydraulic oil there will be compressed to squeeze the top buffer piston 414. At the same time, because the fixed piston 331 moves downward, the space between it and the top lower buffer piston 415 becomes larger, so The top lower buffer piston 415 will be displaced downward. Similarly, in order to maintain the conservation of pressure on both sides, the top upper buffer piston 414 will also descend to maintain the pressure balance on both sides of the top upper buffer piston 414 and the pressure balance on both sides of the top lower buffer piston 415. When the top lower buffer piston 415 descends to the limit of the stroke, the fixed piston 331 continues to descend. At this time, negative pressure will appear between the top lower buffer piston 415 and the fixed piston 331. Secondly, when the movable piston 332 moves downward, the hydraulic oil will be squeezed and exert pressure on the bottom upper buffer piston 424, and the bottom slide rod 351 will move radially inward, which will also pass through the hydraulic The pressurized oil transmits the pressure to the bottom lower buffer piston 425. At this time, the bottom upper buffer piston 424 and the bottom lower buffer piston 425 are close to each other to keep the pressure inside and outside balanced. This design effectively buffers the force transmitted by the hydraulic oil through the compression or expansion changes between the top upper buffer piston 414 and the top lower buffer piston 415, the top lower buffer piston 415 and the fixed piston 331, and the bottom upper buffer piston 424 and the bottom lower buffer piston 425, avoiding the hydraulic oil from directly transmitting rigid pressure, effectively alleviating the pressure on the top slide bar 341, the bottom slide bar 351, and the elastic member 333, and due to the existence of The top upper buffer piston 414 and the top lower buffer piston 415, the top lower buffer piston 415 and the fixed piston 331, and the bottom upper buffer piston 424 and the bottom lower buffer piston 425, which play a buffering role, can effectively prevent the clamping force applied by the top slide bar 341 and the bottom slide bar 351 to the annular workpiece 1 from being a rigid force, and play a good protective role for the various components in the present application. When the stacked annular workpieces 1 are stored for a long time, the pressure of each part is effectively relieved. At the same time, this design also enables the hydraulic oil in the support cylinder 31 to have the function of self-resetting, that is, the top bearing plate 322 has a reset function when the external pressure is lost.

[0067] In the related art, this forging stacking storage device has effective buffering effects due to the top upper buffer piston 414 and the top lower buffer piston 415, the top lower buffer piston 415 and the fixed piston 331, and the bottom upper buffer piston 424 and the bottom lower buffer piston 425. The gas therein is compressed or expanded, which will add a certain load to the sealing performance of the above-mentioned parts. As the storage time increases, the load will exist for a longer time. Once the sealing performance decreases or even fails, the buffering capacity of the above-mentioned parts will fail.

[0068] According to some embodiments of the present application, Figure 2 , Figure 5 , Figure 11-Figure 14 As shown, a reinforcement mechanism 5 is provided on the fixed piston 331 and the buffer mechanism 4, a plurality of pressure relief holes 334 are evenly provided on the movable piston 332, and the reinforcement mechanism 5 includes: an active piston reinforcement component 51, a top outer reinforcement component 52, a top inner reinforcement component 53, a bottom outer reinforcement component 54 and a bottom inner reinforcement component 55.

[0069] like Fig.11 As shown, the active piston reinforcement component 51 is arranged on the side of the fixed piston 331 facing the movable piston 332, and is sealed and slidably connected to the inner wall of the support cylinder 31; the top outer reinforcement component 52 is symmetrically arranged on the side where the top upper buffer piston 414 and the top lower buffer piston 415 are away from each other, and is sealed and slid on the top buffer outer shell 411; the top inner reinforcement component 53 is symmetrically arranged on the side where the top upper buffer piston 414 and the top lower buffer piston 415 are away from each other, and is sealed and slid on the top buffer inner shell 412; the structure and size of the bottom outer reinforcement component 54 are the same as those of the top outer reinforcement component 52, and the two are symmetrically arranged on the side where the bottom upper buffer piston 424 and the bottom lower buffer piston 425 are away from each other, and are sealed and slid on the bottom buffer outer shell 421; the structure and size of the bottom inner reinforcement component 55 are the same as those of the top inner reinforcement component 53, and the two are symmetrically arranged on the side where the bottom upper buffer piston 424 and the bottom lower buffer piston 425 are away from each other, and are sealed and slid on the bottom buffer inner shell 422.

[0070] Specifically, Fig.11 and Fig.12As shown, the active piston reinforcement component 51 includes: an active piston reinforcement ring 511, an active piston reinforcement rubber ring 512 and a first reinforcement through hole 513. The active piston reinforcement ring 511 is fixedly connected to the bottom end of the fixed piston 331, and is sealingly and slidingly matched with the support tube 31; the active piston reinforcement rubber ring 512 is embedded in the outer wall of the active piston reinforcement ring 511, and is sealingly and slidingly matched with the inner wall of the support tube 31; a plurality of first reinforcement through holes 513 are evenly arranged on the circumference of the active piston reinforcement ring 511, and penetrate the active piston reinforcement ring 511 to communicate the inner wall of the active piston reinforcement rubber ring 512 with the bottom side of the fixed piston 331.

[0071] like Fig.11 and Fig.13 As shown, the top outer reinforcement component 52 includes: a buffer piston outer reinforcement ring 521, a buffer piston outer reinforcement rubber ring 522 and a second reinforcement through hole 523. The two buffer piston outer reinforcement rings 521 are symmetrically fixed to the side of the top upper buffer piston 414 and the top lower buffer piston 415 that are away from each other, and are sealed and slidably matched with the top buffer shell 411; the two buffer piston outer reinforcement rubber rings 522 are symmetrically embedded in the outer walls of the two buffer piston outer reinforcement rings 521, and are sealed and slidably matched with the top buffer shell 411; two groups of second reinforcement through holes 523 are symmetrically arranged, and the two symmetrically arranged groups of second reinforcement through holes 523 are respectively and evenly arranged on the two buffer piston outer reinforcement rings 521 in the circumferential direction, and penetrate the two buffer piston outer reinforcement rings 521, so that the two buffer piston outer reinforcement rubber rings 522 are respectively connected to the upper side of the top upper buffer piston 414 and the lower side of the top lower buffer piston 415.

[0072] like Fig.11 and Fig.14 As shown, the top inner reinforcement component 53 includes: a buffer piston inner reinforcement ring 531, a buffer piston inner reinforcement rubber ring 532 and a third reinforcement through hole 533. The two buffer piston inner reinforcement rings 531 are symmetrically fixed to the side of the top upper buffer piston 414 and the top lower buffer piston 415 that are away from each other, and are sealed and slidably matched with the top buffer inner shell 412; the two buffer piston inner reinforcement rubber rings 532 are symmetrically embedded in the inner walls of the two buffer piston inner reinforcement rings 531, and are sealed and slidably matched with the top buffer inner shell 412; two groups of third reinforcement through holes 533 are symmetrically arranged, and the two symmetrically arranged groups of third reinforcement through holes 533 are respectively and evenly arranged on the two buffer piston inner reinforcement rings 531 in the circumferential direction, and penetrate the two buffer piston inner reinforcement rings 531, so that the two buffer piston inner reinforcement rubber rings 532 are respectively connected to the upper side of the top upper buffer piston 414 and the lower side of the top lower buffer piston 415.

[0073] It should be noted that the top outer reinforcement component 52, the top inner reinforcement component 53, the bottom outer reinforcement component 54 and the bottom inner reinforcement component 55 in the embodiment of the present application can be symmetrically arranged on the upper and lower sides of the pistons where they are respectively installed, so as to better improve the sealing performance.

[0074] Therefore, it can be understood that during specific use, when the fixed piston 331 moves downward, the hydraulic oil is squeezed, and the hydraulic oil flows from the pressure relief hole 334 to between the movable piston 332 and the fixed piston 331, and passes through the first reinforced through hole 513 to apply an outward radial force to the active piston reinforced rubber ring 512, thereby forming a better sealing effect between the active piston reinforced rubber ring 512 and the inner wall of the support cylinder 31. The multiple pressure relief holes 334 provided on the movable piston 332 reduce the reaction force exerted on the movable piston 332, and further reduce the pressure exerted on the elastic member 333. Similarly, the outer reinforced rubber ring 522 of the buffer piston located at the top of the support cylinder 31 is subjected to the outward radial force exerted on it by the hydraulic oil at its upper end after passing through the second reinforced through hole 523. At the same time, the inner reinforced rubber ring 532 of the buffer piston is also subjected to the outward radial force exerted on it by the hydraulic oil on this side after passing through the third reinforced through hole 533. The added inward radial force will enhance the sealing performance between the outer reinforced rubber ring 522 of the buffer piston and the top buffer shell 411, as well as the sealing performance between the inner reinforced rubber ring 532 of the buffer piston and the top buffer inner shell 412. During this process, the bottom outer reinforced component 54 and the bottom inner reinforced component 55 at the bottom both enhance their own sealing performance due to the pressure. The top lower buffer piston 415 located in the negative pressure area, the outer reinforced rubber ring 522 of the buffer piston at the bottom and the inner reinforced rubber ring 532 of the buffer piston, although the suction will reduce the sealing performance between themselves and the corresponding top buffer shell 411 and top buffer inner shell 412, they will be affected by the suction and will block the corresponding second reinforced through hole 523 and the third reinforced through hole 533, which will also enhance the sealing effect of the top lower buffer piston 415 to a certain extent.

[0075] It should be noted that the specific model specifications of the supporting base 2 and the elastic member 333 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0076] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
