Abstract
Description
Technical Field
[0001] This utility model relates to the field of tube beam forming technology, and in particular to a high-pressure forming device for the tube beam of a car rear subframe based on intelligent pressure regulation. Background Technology
[0002] As the automotive industry moves towards lightweight and high-strength designs, the rear subframe, as a core component of the chassis, faces increasingly stringent requirements for precision and efficiency in its manufacturing process. Internal high-pressure forming technology, with its advantages of one-time molding of complex cross-section tubular components, reduced welding steps, and improved structural strength, has become a key process in the manufacturing of automotive rear subframe tubular beams.
[0003] However, traditional high-pressure forming devices for automotive rear subframe tube beams based on intelligent pressure regulation have problems such as incomplete wastewater collection and difficulty in effectively intercepting debris flowing with the wastewater when dealing with wastewater after tube blank forming.
[0004] For example, in the rear subframe production line of a new energy vehicle manufacturer, after the first molding is completed, the deionized water inside the tube beam is directly discharged through the drain outlet. The aluminum alloy debris carried by the water flow flows into the workshop's unified drainage pipe along with the wastewater. The debris gradually accumulates at the bends of the pipe, causing blockages in the workshop's drainage pipes. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-pressure forming device for the inner tube beam of a car rear subframe based on intelligent pressure regulation includes a worktable. The top outer wall of the worktable is connected to symmetrically distributed first and second connecting seats. A connecting plate is connected to the top outer wall of the worktable, and a lower mold core is connected to the top outer wall of the connecting plate. The device also includes: a collection mechanism: the collection mechanism includes a mounting groove installed on the top outer wall of the worktable; an intercepting plate is connected inside the worktable; the intercepting plate is connected to the inner walls of both sides of the mounting groove; a brush rod is connected to the top outer wall of the intercepting plate; connecting blocks are connected to the outer walls of both sides of the brush rod; an electric push rod is connected to the inner wall of the worktable; the output end of the electric push rod is connected to one side outer wall of one of the connecting blocks; a guide plate is connected to the outer wall of the intercepting plate away from the electric push rod; a collection box is provided on the outer wall of the guide plate away from the brush rod; and a filter is connected to the bottom outer wall of the intercepting plate; and a return mechanism: the return mechanism is located inside the worktable.

The outer wall of the first connecting pipe is connected to a third water pump. One end of the first connecting pipe is connected to the outer wall of the second connecting seat.
[0010] In this design, the reflux mechanism includes a water tank installed inside the workbench to store liquid flowing in from the inlet pipe, providing a stable liquid reserve for the entire reflux system. An inlet pipe is connected to one outer wall of the water tank to introduce filtered liquid into the tank. A collection chamber is located on the top outer wall of the inlet pipe to collect liquid from the workbench surface.

There is a liquid storage tank, which is used to temporarily store the liquid transported from the second connecting pipe.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0019] The high-pressure forming device for automotive rear subframe tube beam based on intelligent pressure regulation disclosed in this utility model is mainly applied to the scenario where traditional high-pressure forming devices for automotive rear subframe tube beam based on intelligent pressure regulation are used to treat wastewater after tube blank forming, which has the problems of incomplete wastewater collection and difficulty in effectively intercepting debris flowing with the wastewater.
[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A high-pressure forming device for the inner tube beam of a car rear subframe based on intelligent pressure regulation includes a worktable 1. The top outer wall of the worktable 1 is connected to symmetrically distributed first connecting seats 3 and second connecting seats 4. The top outer wall of the worktable 1 is connected to a connecting plate, and the top outer wall of the connecting plate is connected to a lower mold core 16. The device also includes: a collection mechanism: the collection mechanism includes an installation groove installed on the top outer wall of the worktable 1. An intercepting plate 17 is connected inside the worktable 1. The intercepting plate 17 is connected to the inner walls of both sides of the installation groove. A brush rod 20 is connected to the top outer wall of the intercepting plate 17. Connecting blocks are connected to the outer walls of both sides of the brush rod 20. An electric push rod 21 is connected to the inner wall of the worktable 1. The output end of the electric push rod 21 is connected to the outer wall of one side of one of the connecting blocks. A guide plate 18 is connected to the outer wall of the intercepting plate 17 away from the electric push rod 21. A collection box 14 is provided on the outer wall of the guide plate 18 away from the brush rod 20. A filter 19 is connected to the bottom outer wall of the intercepting plate 17. A return mechanism: the return mechanism is located inside the worktable 1.
[0021] Wastewater from shaping the tube blank is poured into the mounting groove inside the workbench 1. At this time, the interceptor plate 17 installed in the mounting groove initially intercepts the debris flowing with the wastewater, trapping larger metal debris and impurities on the plate surface. After the equipment has been running for a period of time, the electric push rod 21 installed on the inner wall of the workbench 1 is activated. The output end of the electric push rod 21 is connected to one side of the outer wall of one of the connecting blocks. At the same time, a brush rod 20 is connected to one side of the outer wall of the connecting block. Thus, the electric push rod 21 drives the brush rod 20 to reciprocate along the surface of the interceptor plate 17, thereby cleaning the waste material attached to the surface of the interceptor plate 17. At this time, a guide plate 18 is connected to the outer wall of the interceptor plate 17 away from the electric push rod 21. The guide plate 18 is inclined and is used to guide the waste material cleaned by the brush rod 20 so that it can slide smoothly into the collection box 14 for regular cleaning and reduce the frequency of manual cleaning.
[0022] The bottom outer wall of the connecting plate is higher than the top outer wall of the brush rod 20, which provides space for the reciprocating motion of the brush rod 20.
[0023] In particular, the collection box 14 is a removable structure, which makes it easy to clean the debris swept into the collection box 14 by the brush rod 20.
[0024] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5In a preferred embodiment, the reflux mechanism includes a water tank 23 installed inside the workbench 1. An inlet pipe 22 is connected to one outer wall of the water tank 23. A collection chamber is provided on the top outer wall of the inlet pipe 22. A second connecting pipe 13 is connected to the outer wall of the water tank 23 away from the inlet pipe 22. The same second water pump 12 is connected to one outer wall of the two second connecting pipes 13. A storage tank 11 is connected to one outer wall of one of the second connecting pipes 13. A first connecting pipe 10 is connected to one outer wall of the storage tank 11. A third water pump 15 is connected to one outer wall of the first connecting pipe 10. One end of the first connecting pipe 10 is connected to one outer wall of the second connecting seat 4.
[0025] The reflux mechanism includes a water tank 23 installed inside the workbench 1 to store liquid flowing in from the inlet pipe 22, providing a stable liquid reserve for the entire reflux system. One outer wall of the water tank 23 is connected to the inlet pipe 22, which introduces the liquid filtered through the filter 19 into the water tank 23. The top outer wall of the inlet pipe 22 has a collection chamber to collect liquid from the surface of the workbench 1. A second connecting pipe 13 is connected to the outer wall of the water tank 23 away from the inlet pipe 22, serving as a channel for liquid to flow out of the water tank 23 and transport the liquid in the water tank 23 to subsequent components. The outer walls of both second connecting pipes 13 are connected to the same second water pump 12, and one of the second connecting pipes 13 has a liquid storage device connected to its outer wall. The storage tank 11 is used to temporarily store the liquid transported from the second connecting pipe 13. The outer wall of one side of the storage tank 11 is connected to the first connecting pipe 10, which is the channel for the liquid to flow out of the storage tank 11. It can guide the liquid in the storage tank 11 to the third water pump 15. The outer wall of one side of the first connecting pipe 10 is connected to the third water pump 15, which provides power for the liquid transport. Through its own suction action, the liquid in the storage tank 11 is pumped through the first connecting pipe 10 to the second connecting seat 4. One end of the first connecting pipe 10 is connected to the outer wall of one side of the second connecting seat 4, which can guide the liquid transported by the third water pump 15 into the second connecting seat 4, providing liquid for the components related to the second connecting seat 4 and ensuring their normal operation.
[0026] The collection chamber is located directly below the filter 19. The collection chamber has a wedge-shaped structure, and the liquid flows into the inlet pipe 22 in a concentrated manner, which facilitates the collection of the liquid.
[0027] Specifically, the water tank 23 is installed inside the workbench 1, and an inspection door is installed on one outer wall of the workbench 1. The water tank 23 and the liquid inlet pipe 22 installed inside the workbench 1 can be easily maintained by opening the inspection door.
[0028] Reference Figure 1 and Figure 2In a preferred embodiment, the top outer wall of the worktable 1 is provided with four guide pillars 5 distributed at equal intervals. The ends of the four guide pillars 5 away from the worktable 1 are connected to a second connecting plate 8. The top outer wall of the second connecting plate 8 is connected to a hydraulic rod 7. The output end of the hydraulic rod 7 is connected to a first connecting plate 6. The bottom outer wall of the first connecting plate 6 is connected to an upper mold core 9. A control console 2 is installed on one side outer wall of the worktable 1. The connecting plate is connected to the inner walls of both sides of the mounting groove.
[0029] Four guide pillars 5 installed on the top outer wall of the workbench 1 are used to guide the movement of the first connecting plate 6, thereby facilitating the closing of the upper mold core 9 installed on the bottom outer wall of the second connecting seat 4 and the lower mold core 16 on the top outer wall of the connecting plate. At this time, the hydraulic rod 7 is controlled by the control console 2 to output pressure to the first connecting plate 6. Then, the upper mold core 9 is driven to move by starting the hydraulic rod 7, thereby achieving the closing of the upper mold core 9 and the lower mold core 16.
[0030] Working principle: During use, the operator places the tube blank to be processed into the groove on the outer wall of the lower mold core 16 at the top of the worktable 1. The equipment is started through the control console 2, so that the four guide pillars 5 provide guidance for the movement of the first connecting plate 6, ensuring that the upper mold core 9 and the lower mold core 16 are precisely aligned. At this time, the control console 2 controls the hydraulic rod 7 to output pressure according to the preset forming parameters, pushing the first connecting plate 6 to move the upper mold core 9 downward along the guide pillars 5 until it closes with the lower mold core 16, completing the mold closing action before the tube beam is formed. After the mold is closed, the device connects to the tube through the second connecting seat 4. High-pressure liquid is injected into the billet. Simultaneously, control console 2, based on an intelligent pressure regulation algorithm, monitors the hydraulic system pressure changes in real time. Hydraulic rod 7 dynamically adjusts its output pressure according to the instructions from control console 2. This, combined with the high-pressure liquid inside the billet, causes the billet to undergo plastic deformation under the constraint of the mold cavity, ultimately forming a rear subframe tube beam that meets dimensional requirements. During this process, the first connecting seat 3 and the second connecting seat 4 ensure the sealing and positioning of both ends of the billet, guaranteeing the stability of high-pressure forming. After forming, the high-pressure liquid inside the billet is discharged into the mounting groove on the top of the worktable 1. The interceptor plate 17 performs preliminary filtration of wastewater, trapping larger metal fragments on its surface. After the equipment has been running for a period of time, the control console 2 activates the electric push rod 21, whose output end drives the brush rod 20 to reciprocate along the surface of the interceptor plate 17 via the connecting block, cleaning the waste adhering to the plate surface. The inclined guide plate 18 guides the cleaned waste into the removable collection box 14, achieving centralized collection of the fragments. At the same time, the filter 19 at the bottom of the interceptor plate 17 performs secondary filtration of the fine particles and liquid that have passed through the interceptor plate 17. The filtered liquid flows into the wedge-shaped collection chamber at the top of the inlet pipe 22. The filtered liquid then enters the water tank 23 via the inlet pipe 22. The filtered liquid stored in the water tank 23 is transported to the second water pump 12 via the second connecting pipe 13. Part of the liquid is temporarily stored in the storage tank 11 via the second connecting pipe 13 to balance the liquid supply and demand of the system. When liquid needs to be injected into the tube blank again, the third water pump 15 draws liquid from the storage tank 11 via the first connecting pipe 10, pressurizes it, and transports it to the second connecting seat 4 for reuse in tube beam forming, realizing the reuse of liquid. The inspection door on one side of the workbench 1 can be opened at any time to facilitate the maintenance of the return mechanism components such as the water tank 23 and the inlet pipe 22. The control console 2 displays the equipment operating parameters in real time. When an abnormality is detected, an alarm is issued in time and maintenance is prompted to ensure the continuous and stable operation of the equipment.
[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
