Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a curved hydraulic dam surface forming device. Background Art

[0002] Arc hydraulic dam is a new type of water conservancy engineering facility, which is widely used in agricultural irrigation, fishery, ship lock, seawater tidal barrier, urban river landscape project and small hydropower station construction. Arc hydraulic dam is mainly composed of arc dam surface, hydraulic rods, support rods, hydraulic cylinders and hydraulic pump station. Its working principle is to use a row of hydraulic cylinders to directly push the back of the movable water retaining dam surface, press the movable water retaining dam surface with the bottom as the axis to the water surface or lower it, so as to realize the operation of raising the dam to retain water and lowering the dam to discharge flood.

[0003] The dam surface of the arc-shaped hydraulic dam is automatically made by stamping equipment during the production and processing. The steel plate is directly stamped and processed into an arc-shaped dam surface by the stamping equipment in conjunction with the forming mold. After the stamping is completed, the formed dam surface is manually removed from the mold by the staff, and the handling and transfer requires a lot of manpower. In the existing utility model patent with application number 202122512675.2, a cylinder is set to drive the lower mold to rotate. Although automatic unloading after the dam surface is formed can be achieved, a large number of electronic control devices are added to the stamping equipment, making the production and subsequent maintenance costs of the entire device higher. Secondly, under the stress of the stamping equipment, the formed dam surface will form an interlocking state with the lower mold. Simply relying on the lower mold in a vertical state often cannot complete the unloading operation. Even if the unloading operation can be completed, the lower mold in a vertical state cannot provide a good buffer for the formed dam surface, and the unloading process is not smooth enough, which can easily cause the dam surface of the arc-shaped hydraulic dam to be damaged due to bumps during the unloading process. Therefore, the present application provides a dam surface forming device for an arc-shaped hydraulic dam to meet the needs. Summary of the invention

[0007] Optionally, the hooking assembly includes a hooking plate fixedly connected to the outside of the upper mold and a hooking groove opened on the outside of the lower mold, a fixing rod is fixedly connected in the hooking groove, and the position of the hooking groove on the lower mold corresponds to the position of the hooking plate outside the upper mold.

[0008] Optionally, the end of the hooking plate is inclined toward the center of the upper mold and fixedly connected with a hooking end, and a first weakening groove is provided on the outside of the hooking plate, and a second guide surface located above the hook groove is provided on the top of the lower mold, and the length of the upper mold is smaller than the length of the hook groove and the fixing rod.

[0009] Optionally, the first limiting assembly includes a sleeve fixedly connected to the inner side of the movable groove, a transmission rod is sleeved in the sleeve, one end of the transmission rod extends to the outside of the sleeve and is fixedly connected to a first connecting seat, and the first connecting seat is movably connected to the lower mold via a rotating rod.

[0010] Optionally, one end of the transmission rod away from the first connecting seat is located in the sleeve and fixedly connected to the limiting disk, a telescopic cavity adapted to the shape of the limiting disk is opened in the sleeve, and a second spring is fixedly connected between the sleeve and the limiting disk.

[0011] Optionally, the second limiting assembly includes a third connecting seat fixedly connected to the receiving groove and a second connecting seat fixedly connected to the bottom of the upper mold, and an elastic plate is connected between the second connecting seat and the third connecting seat.

[0012] Optionally, the two ends of the elastic plate are respectively fixedly connected with a first connecting rod and a second connecting rod, the first connecting rod and the second connecting seat are movably connected via a bearing, and the second connecting rod and the third connecting seat are movably connected via a bearing.

[0013] Optionally, the elastic plate is V-shaped as a whole, and a second weakened groove is provided in the middle of the elastic plate, the thickness of the second weakened groove is smaller than the thickness of the elastic plate, and the elastic plate is provided with evenly distributed lightweight openings.

[0014] Optionally, the ejection assembly includes an ejection rod symmetrically installed in the lower mold, a disc is fixedly connected to the outside of the ejection rod, an active cavity adapted to the shape of the disc is opened in the lower mold, and a first spring is fixedly connected between the disc and the active cavity.

[0015] Optionally, one end of the ejector rod is flush with the inner wall of the lower mold, and the other end of the ejector rod extends to the outside of the lower mold to form a pressure surface, and the outside of the first connecting rod is fixedly connected to a pressure block, and the pressure block is provided with an inclined surface adapted to the shape of the pressure surface.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting the hooking component and the first guide surface, after the upper mold and the lower mold cooperate to perform the forming processing operation of the dam surface, the hooking component can be used to pull the lower mold to deflect and move during the process of the upper mold rising and resetting, so that the lower mold is in an inclined state, and cooperates with the first guide surface to form an inclined surface that allows the formed dam surface to slide down. This not only realizes automatic unloading after the dam surface is processed and formed, but also does not increase the number of electronically controlled equipment, effectively controlling the production and maintenance costs of the device.

[0018] By setting the first limit assembly and the second limit assembly, when the lower mold is driven by the hook assembly to displace and deflect, the first limit assembly and the second limit assembly can be displaced and deformed following the movement of the lower mold, so as to limit the movement range of the lower mold, ensure the stability of the lower mold during the deflection process and limit the state of the lower mold after deflection, and ensure that the state of the lower mold after deflection can allow the formed dam surface to slide down, so as to avoid the formed dam surface falling directly during the unloading process and being damaged due to bumps.

[0019] By setting the ejector assembly, the elastic plate in the second limiting assembly will be deformed during the deflection and displacement of the lower mold, which will then drive the first connecting rod to deflect at the bottom of the lower mold, and drive the pressure block to shift, and finally rely on the extrusion of the pressure block to push the ejector rod to move, so that the ejector rod can eject the dam surface formed in the lower mold, and cleverly make the structure of the ejector assembly and the structure of the second limiting assembly cooperate, avoiding the situation that the dam surface still cannot fall after the lower mold is deflected and tilted, and further ensuring the unloading effect of the device.

[0020] By setting the first weakening groove and the first limit assembly and the second limit assembly in the hooking assembly, after the lower mold is deflected to a certain extent under the action of the hooking assembly, it will be restricted by the first limit assembly and the second limit assembly and cannot continue to move. At this time, the continuous rise of the lifting platform will cause the hooking plate in the hooking assembly to bend and deform at the first weakening groove, so that the hooking end is disconnected from the fixed rod, ending the upward pulling action on the lower mold, and then the lower mold can be quickly reset by relying on the first limit assembly and the second limit assembly after completing the unloading operation of the dam surface after forming, and continue the next group of dam surface forming processing, thereby ensuring the working efficiency of the device.

[0041] like Figures 1 to 11As shown, an embodiment of the present invention provides an arc-shaped hydraulic dam surface forming device, comprising a base 1, four evenly distributed guide columns 3 are fixedly connected to the top of the base 1, and a lower mold 4 is assembled on the top of the base 1, a lifting platform 2 is sleeved on the outside of the guide columns 3, and an upper mold 12 that matches the shape of the lower mold 4 is arranged at the bottom of the lifting platform 2, and the top of the lifting platform 2 is connected to a hydraulic drive device. During the operation of the device, the lifting platform 2 and the upper mold 12 can be driven by the hydraulic drive device to move up and down as a whole along the guide of the guide columns 3, so that the upper mold 12 can cooperate with the lower mold 4 to complete the dam surface forming processing of the arc-shaped hydraulic dam. The top of the base 1 is provided with symmetrically distributed movable grooves 6 and storage grooves 9, and the outer side of the base 1 is provided with a first guide surface 10. The movable grooves 6 and storage grooves 9 can provide storage space for other structures arranged on the base 1, keep the upper surface of the base 1 flat, and indirectly keep the lower mold 4 in a horizontal state, so that the lower mold 4 can obtain sufficient support force when cooperating with the upper mold 12 to form the dam surface. The first guide surface 10 provided on the outside of the base 1 can provide guidance for the dam surface during the unloading operation of the dam surface by the lower mold 4, so that the unloading process of the formed dam surface is smoother, and the dam surface is prevented from directly turning down and colliding with other objects to cause damage;

[0042] The hooking assembly is used for the associative connection between the upper mold 12 and the lower mold 4. The hooking assembly is connected to the upper mold 12 and the lower mold 4 respectively. The hooking assembly can use the lifting and lowering of the lifting platform 2 and the upper mold 12 during the working process to drive the lower mold 4 to perform deflection and displacement, so that it can be quickly removed from the lower mold 4 after the dam surface is processed and formed; the first limiting assembly is used for guiding and limiting the deflection and displacement process of the lower mold 4, and the first limiting assembly is connected to the movable groove 6; the second limiting assembly is used for resetting the lower mold 4 after the deflection and displacement, and the second limiting assembly is respectively connected to the receiving groove 9 and the lower mold 4; the setting of the first limiting assembly and the second limiting assembly can provide guidance for the offset activity of the lower mold 4, limit the deflection state of the lower mold 4, and limit the activity range of the lower mold 4, so as to ensure the lower mold 4 is in an inclined state during the unloading process, and can cooperate with the first guide surface 10 to easily form the dam surface to fall, ensuring smooth unloading of the dam surface. At the same time, the first limit assembly and the second limit assembly can also drive the lower mold 4 to quickly reset after the lower mold 4 completes the unloading operation, and perform the molding process of the next group of dam surfaces, so as to ensure the overall working efficiency of the device. The ejection assembly is used for ejecting and unloading the dam surface formed after the lower mold 4 is deflected and displaced. The ejection assembly is connected to the lower mold 4. The ejection assembly can utilize the transmission of the structure in the second limit assembly to work synchronously during the deflection unloading process of the lower mold 4, and eject the dam surface formed in the lower mold 4, so as to avoid the dam surface formed in the lower mold 4 being embedded in the lower mold 4 under the action of stress and unable to fall naturally, thereby ensuring the normal unloading operation.

[0043] In this embodiment, if Figures 1 to 6 As shown, the hooking assembly includes a hooking plate 11 fixedly connected to the outside of the upper mold 12 and a hooking groove 7 opened on the outside of the lower mold 4, a fixing rod 8 is fixedly connected in the hooking groove 7, the position of the hooking groove 7 on the lower mold 4 corresponds to the position of the hooking plate 11 outside the upper mold 12, the end of the hooking plate 11 is inclined toward the center of the upper mold 12 and is fixedly connected with a hooking end 22, and a first weakening groove 21 is opened on the outside of the hooking plate 11. The opening of the first weakening groove 21 makes the thickness of the hooking plate 11 at the first weakening groove 21 thinner and weaker, and it is more likely to deform after being subjected to external force. When the device as a whole is not working, it is in the first state, and the lower mold The mold 4 and the upper mold 12 are separated from each other, and a second guide surface 23 located above the hook groove 7 is provided on the top of the lower mold 4. The length of the upper mold 12 is less than the length of the hook groove 7 and the fixing rod 8. When the lifting platform 2 drives the upper mold 12 to cooperate with the lower mold 4 for stamping, the upper mold 12 drives the hooking plate 11 to descend. As the upper mold 12 approaches the lower mold 4, the hooking end 22 at the end of the hooking plate 11 will contact the second guide surface 23 on the lower mold 4. After the hooking end 22 is squeezed by the second guide surface 23, the hooking plate 11 will be deformed at the first weakened groove 21, and avoidance will occur so that the hooking end 22 can enter the hook groove on the lower mold 4. 7, after the hooking end 22 enters the hooking groove 7, it contacts with the fixing rod 8 again and avoids until the end of the hooking end 22 moves to the bottom of the fixing rod 8. At this time, the lower mold 4 and the upper mold 12 are also completely fitted to form a stamping process on the steel plate, so that the dam surface is formed, and the hooking plate 11 is also restored under the action of its own elastic force, so that the hooking end 22 and the fixing rod 8 are in a hooked state. After the upper mold 12 completes the stamping forming, it follows the lifting platform 2 to rise and reset. At this time, the hooking end 22 and the fixing rod 8 in the hooked state can drive the lower mold 4 to follow the rise of the upper mold 12 to produce deflection and displacement, so that the lower mold 4 can be in a tilted state, After the forming, the dam surface is unloaded, and the lifting and lowering activities of the stamping equipment are cleverly used to drive the lower mold 4 to complete the deflection unloading operation, without adding additional electronic control equipment, effectively controlling the production and subsequent maintenance costs of the device. When the lower mold 4 is tilted under the pulling action of the hooking assembly, the device as a whole is in the second state. After the lower mold 4 completes the unloading operation, the lifting platform 2 continues to drive the upper mold 12 to rise, so that the hooking plate 11 can be deformed at the first weakened groove 21 again, until the hooking end 22 is separated from the fixed rod 8, and the hooking state between the hooking plate 11 and the lower mold 4 is released, so that the lower mold 4 can be reset and the next set of dam surface forming processing can be carried out.

[0044] In this embodiment, if Figures 2 to 4 as well as Figure 7 and Fig.11As shown, the first limiting assembly includes a sleeve tube 13 fixedly connected to the inner side of the movable groove 6, a transmission rod 14 is sleeved in the sleeve tube 13, one end of the transmission rod 14 extends to the outside of the sleeve tube 13 and is fixedly connected to a first connecting seat 15, the first connecting seat 15 and the lower mold 4 are movably connected through a rotating rod, the rotating rod is located on the outer side of one end of the lower mold 4 away from the hook groove 7 and the fixed rod 8, the rotating rod and the first connecting seat 15 are movably connected through a bearing, the bottom of the first connecting seat 15 is an inverted T-shape, the movable groove 6 is adapted to the bottom shape of the first connecting seat 15, when the lower mold 4 is affected by the hooking assembly and produces displacement movement, the first connecting seat 15 will follow the displacement of the lower mold 4 and slide in the movable groove 6, the end of the transmission rod 14 away from the first connecting seat 15 is located in the sleeve tube 13 and fixedly connected to the limiting disk 31, a telescopic cavity 32 adapted to the shape of the limiting disk 31 is opened in the sleeve tube 13, and the sleeve tube 13 and the limiting disk 31 are fixedly connected There is a second spring 30. The first connecting seat 15 drives the transmission rod 14 to slide in the telescopic cavity 32 inside the sleeve tube 13 during the displacement movement of the lower mold 4, and the second spring 30 contracts. During the entire movement and deflection of the lower mold 4, the first connecting seat 15 is limited by the movable groove 6, and the transmission rod 14 is also limited by the sleeve tube 13 to keep the end connected between the lower mold 4 and the first connecting seat 15 always in contact with the top of the base 1. In the matching hook assembly, one end of the fixed rod 8 is set to pull the lower mold 4, so that the lower mold 4 as a whole deflects with the connection between the first connecting seat 15 and the rotating rod as the rotation axis, so that the lower mold 4 can be in an inclined state after being pulled, and the inclined surface formed by the first guide surface 10 is convenient for the lower mold 4 to unload the formed dam surface. The inclined surface formed by the lower mold 4 itself and the inclined surface formed by the first guide surface 10 can provide a buffer for the unloading process of the dam surface, avoiding the dam surface from falling directly and being damaged due to collision.

[0045] In this embodiment, if Figures 4 to 10As shown, the second limiting assembly includes a third connecting seat 17 fixedly connected to the storage groove 9 and a second connecting seat 16 fixedly connected to the bottom of the upper mold 12, an elastic plate 20 is connected between the second connecting seat 16 and the third connecting seat 17, and the two ends of the elastic plate 20 are respectively fixedly connected with a first connecting rod 18 and a second connecting rod 19, the first connecting rod 18 and the second connecting seat 16 are movably connected by a bearing, and the second connecting rod 19 and the third connecting seat 17 are movably connected by a bearing, the elastic plate 20 is V-shaped as a whole, and a second weakening groove 28 is provided in the middle of the elastic plate 20, the thickness value at the second weakening groove 28 is less than the thickness value of the elastic plate 20, the setting of the second weakening groove 28 makes the elastic plate 20 thinner at the second weakening groove 28, the strength is weaker, and it is more likely to deform after being subjected to external force, and the elastic plate 20 is provided with uniformly distributed lightweight openings, and the setting of the lightweight openings can not affect the structure of the elastic plate 20 too much. On the premise of strength, the weight of the elastic plate 20 is reduced, and the production cost of the elastic plate 20 is reduced. When the lower mold 4 is pulled and deflected under the action of the hooking assembly, the third connecting seat 17 is located in an inconvenient position in the storage groove 9, and the second connecting seat 16 follows the displacement and deflection of the lower mold 4 and produces a corresponding displacement. The elastic plate 20 will also follow the displacement of the second connecting seat 16 and produce bending deformation at the second weakened groove 28 to adapt to the position change of the second connecting seat 16. The second connecting rod 19 and the first connecting rod 18 respectively rotate relative to the third connecting seat 17 and the second connecting rod 19, so that the elastic plate 20 accumulates elastic potential energy. When the hooking assembly releases the pulling effect on the lower mold 4, the elastic plate 20 can cooperate with the elastic force of the second spring 30 in the first limit assembly under the action of its own elastic force to drive the lower mold 4 to complete the reset operation as a whole quickly, thereby ensuring the reset efficiency of the device after unloading, thereby indirectly improving the working efficiency of the entire device.

[0046] In this embodiment, if Figures 7 to 10As shown, the ejection assembly includes an ejector rod 5 symmetrically installed in the lower mold 4, the outer part of the ejector rod 5 is fixedly connected with a disc 25, the lower mold 4 is provided with an active cavity 24 adapted to the shape of the disc 25, and a first spring 26 is fixedly connected between the disc 25 and the active cavity 24. One end of the ejector rod 5 is flush with the inner wall of the lower mold 4, and the other end of the ejector rod 5 extends to the outside of the lower mold 4 and is provided with a pressure surface 27. One end of the ejector rod 5 extending to the inner wall of the lower mold 4 needs to be flush with the inner wall of the lower mold 4 to ensure the flatness of the inner wall of the lower mold 4, and then to ensure the dam surface shape of the arc-shaped hydraulic dam formed by the stamping of the lower mold 4 and the upper mold 12. The outer part of the first connecting rod 18 is fixedly connected with a pressing block 29, and the pressing block 29 is provided with an inclined surface adapted to the shape of the pressure surface 27. The elastic plate 20 in the second limiting assembly will deform during the deflection and displacement of the lower mold 4. In this process, the first connecting rod The connecting rod 18 and the second connecting seat 16 rotate relative to each other, and the pressing block 29 on the first connecting rod 18 deviates following the rotation of the first connecting rod 18. The inclined surface on the pressing block 29 is released from the pressure surface 27 on the movable groove 6 and extrusion is generated. The extrusion of the pressing block 29 pushes the ejector rod 5 to move, so that the ejector rod 5 can eject the dam surface formed in the lower mold 4, and the structure of the ejector assembly is cleverly matched with the structure of the second limit assembly to avoid the situation that the dam surface still cannot fall after the lower mold 4 is deflected and tilted. In the process of the ejector rod 5 being squeezed and moving in the lower mold 4, the disk 25 is driven to slide in the movable cavity 24 and the first spring 26 is compressed. After the lower mold 4 is reset, the elastic plate 20 and the first connecting rod 18 are also reset synchronously, and the ejector rod 5 can be restored under the action of the elastic force of the first spring 26, so that the lower mold 4 can cooperate with the upper mold 12 again to perform stamping and forming of the dam surface after resetting.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention.
