Description

Technical Field

[0001] This invention relates to the field of automotive body shaping equipment technology, and in particular to a shaping device and method for the body of a new energy vehicle. Background Technology

[0002] Structural components refer to physical entities with a certain shape that can withstand loads. Because automobiles need to carry users for high-speed movement, their bodies must have sufficient structural strength. Therefore, automobile bodies contain a large number of structural components. In addition to improving the body's sturdiness through special shapes, manufacturers also use aluminum alloy materials to further strengthen the body's strength. At certain curved locations on the body, in order to ensure its load-bearing capacity, workers generally do not use welding methods, but instead use stamping methods to prepare the structural components. Current stamping equipment is mostly composed of two main parts: an operating table and a stamping module. The operating table is used to place and position the structural components to be stamped, while the stamping module is responsible for the subsequent stamping and forming operations. After the aluminum alloy car body is formed, the outer surface usually needs to be polished.

[0003] In the prior art, the utility model patent with patent application number CN202222913807.7 discloses "an online automatic shaping device for PTC heater heating core components of new energy vehicles, including a shaping bracket, a shaping lifting platform, a first shaping mechanism, and a second shaping mechanism. The shaping bracket is located on the heating chip carrier conveyor line. The shaping bracket is equipped with a lifting cylinder and a guide assembly connected to the shaping lifting platform. The first shaping mechanism has a first shaping clamping assembly that moves horizontally laterally, used to center and clamp and shape multiple rows of heating core components. The second shaping mechanism has a second shaping clamping assembly that moves horizontally longitudinally, used to clamp and shape the head and tail ends of multiple rows of heating core components. This utility model can effectively shape and adjust the PTC heater heating core components, ensuring that the assembly accuracy between the components in the heating core component meets the requirements and reducing the generation of defective products." However, it still has the following drawbacks:

[0004] (1) The upper die of the stamping and forming equipment has a single function and the automation level of unloading after the shell is formed is low;

[0005] (2) The pressure shaping device has poor integration with other shaping processes, which is not conducive to improving the shell shaping efficiency. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing stamping and forming equipment having single upper and lower module functions, low automation of loading and unloading after shell forming, and poor integration of the pressure forming device with other forming processes, which is not conducive to improving shell forming efficiency. Therefore, this invention proposes a forming device for the shell of new energy vehicles.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A cover shell covering the periphery of the second hydraulic cylinder is fixedly installed on the horizontal section of the gantry. The upper shaping seat and the shaping module are provided with adsorption channels that communicate with each other.

[0020] Preferably, the adsorption mechanism includes an L-shaped plate fixedly installed on the outer wall of the upper shaping seat, a vacuum pump fixedly installed on the vertical section of the L-shaped plate, the output end of the vacuum pump communicating with the adsorption channel located on the upper shaping seat, and the end of the adsorption channel away from the vacuum pump facing the lower shaping seat.

[0021] Preferably, the telescopic adjustment mechanism includes a third hydraulic cylinder fixedly installed on the top of the base, and the telescopic end of the third hydraulic cylinder is fixedly connected to the mounting base.

[0022] Preferably, the first surface treatment mechanism includes a drive shaft symmetrically mounted on the outer wall of the mounting base, and an eccentric disk with equidistant distribution is fixedly sleeved on the outer wall of the drive shaft, and a uniformly distributed first polishing brush is fixedly connected to the outer wall of the eccentric disk.

[0023] Preferably, the auxiliary positioning mechanism includes a mounting frame fixedly installed on the outer wall of the mounting base.

[0025] A shaping method for a shaping device used in the shell of a new energy vehicle includes the following steps:

[0026] S1: Place the car body to be shaped into the shaping groove on the lower shaping seat, then move the lower shaping seat to the designated position using the vertical guide rail and stop. Then activate the first hydraulic cylinder to extend it, thereby causing the constraint block to engage with the positioning groove on the lower shaping seat, so that the lower shaping seat is directly below the upper shaping seat.

[0027] S2: Then, the second hydraulic cylinder is activated to extend it, thereby driving the shaping module at the bottom of the upper shaping seat to pressurize and shape the shell in the shaping groove. After the shaping is completed, the vacuum pump is activated to generate negative pressure in the adsorption channel. The negative pressure generated by the adsorption channel on the shaping module adsorbs the shaped car body shell. Then, the second hydraulic cylinder is controlled to retract, thereby realizing the unloading function after pressurization and shaping, which solves the problem of the single function of the upper shaping seat in the existing technology.

[0028] S3: After the pressure shaping is completed, the vacuum pump is not turned on. Only the second hydraulic cylinder is controlled to retract, which drives the upper shaping seat to move upward. Then the third hydraulic cylinder is turned on to extend it. The extension of the third hydraulic cylinder drives the mounting seat to move towards the lower shaping seat, which in turn drives the first surface treatment mechanism to move into the shaping groove at the top of the lower shaping seat. This causes the first polishing brush to contact the outer shell in the shaping groove. At the same time, the electromagnet is de-energized, the magnetic plate separates from the electromagnet, and the rebound force of the torsion spring drives the positioning block to rotate out of the mounting frame. This causes the positioning wheel to contact the outer shell under the torsion force of the torsion spring, realizing the auxiliary positioning function in the outer shell polishing process and realizing the combination of the polishing mechanism and the pressure shaping mechanism. Then the drive shaft is turned on, which drives the eccentric disk to rotate, which in turn drives the first polishing brush to polish the upper surface of the outer shell.

[0029] S4: Simultaneously activate the drive cam, which drives the third grinding brush to rotate, thereby achieving the grinding function of areas that the two sets of first grinding brushes cannot reach. During the rotation of the drive cam, the touch rod is driven to move back and forth, which in turn drives the gear connected to the touch rod to rotate back and forth. The gear drives the second grinding brush to rotate back and forth through the rotating shaft, further achieving the grinding function of areas that the two sets of first grinding brushes cannot reach, while increasing the grinding range of areas that the first grinding brushes cannot contact.

[0030] S5: After the upper surface of the shell is polished, the electromagnet is energized, and then the third hydraulic cylinder is activated to retract, thereby driving the mounting base and its connected first surface treatment mechanism to move away from the lower shaping base. Then, the shell is attracted by the adsorption mechanism and the adsorption channels on the upper shaping base and the shaping module at its bottom. Then, the second hydraulic cylinder is retracted to place it above the lower shaping base. Then, the telescopic adjustment mechanism is extended to move the first surface treatment mechanism below the upper shaping base. At the same time, the electromagnet on the auxiliary positioning mechanism is de-energized to realize the positioning function of the shell attracted by the shaping module. Then, the lower surface of the shell is treated by the first surface treatment mechanism and the second surface treatment mechanism to realize the combination of pressure shaping and surface treatment of the car shell, and at the same time realize the polishing and flipping function of the shell.

[0031] Compared with the prior art, the present invention provides a shaping device for the shell of a new energy vehicle, which has the following beneficial effects:

[0032] 1. The shaping device for the outer shell of the new energy vehicle realizes the function of pressurizing and shaping the shell in the shaping groove through the setting of the lower shaping seat and the pressurizing shaping mechanism.

[0033] 2. This shaping device for new energy vehicle shells, through the cooperation of an adsorption mechanism and a pressure shaping mechanism, activates a vacuum pump to generate negative pressure in the adsorption channels. The negative pressure generated in the adsorption channels on the shaping module then adsorbs the shaped car shell. The second hydraulic cylinder is then controlled to contract, thereby realizing the unloading function after pressure shaping. This solves the problem of the single function of the upper shaping seat and the inconvenience of unloading in the existing technology.

[0034] 3. The shaping device for the outer shell of the new energy vehicle combines the pressure shaping and surface treatment of the outer shell through the first surface treatment mechanism, the second surface treatment mechanism and the pressure shaping mechanism. At the same time, it realizes the function of grinding and flipping the outer shell. This solves the problem that the pressure shaping device is poorly integrated with other shaping processes in the prior art, which is not conducive to improving the shaping efficiency of the shell.

[0035] 4. The shaping device for the outer shell of this new energy vehicle, through the set auxiliary positioning mechanism, realizes the positioning function during the shell grinding process, ensuring the stability of the shell surface shaping. Attached Figure Description

The extension of the third hydraulic cylinder 620 drives the mounting base 610 to move towards the lower shaping seat 20, thereby driving the first surface treatment mechanism 70 to move into the shaping groove at the top of the lower shaping seat 20, so that the first polishing brushes 730 abut against the outer shell in the shaping groove, realizing the combination of the polishing mechanism and the pressure shaping mechanism 40.

When the electromagnet 820 is de-energized, the magnetic plate 860 separates from the electromagnet 820, and the angle between the positioning block 830 and the electromagnet 820 is acute. When the electromagnet 820 is energized, the magnetic plate 860 and the electromagnet 820 are attached by magnetic attraction. At the same time, the first surface treatment mechanism 70 is located above the lower shaping seat 20, the electromagnet 820 is de-energized, the magnetic plate 860 separates from the electromagnet 820, and the rebound force of the torsion spring 850 drives the positioning block 830 to rotate out of the mounting frame 810, thereby causing the positioning wheel 840 to abut against the outer shell under the torque of the torsion spring 850, realizing the auxiliary positioning function in the shell grinding process.

[0063] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The second surface treatment mechanism 90 includes a drive cam 910 fixedly mounted on the outer wall of the mounting frame 810, a constraint plate 920 on the outer wall of the mounting frame 810, an actuating rod 930 slidably connected to the constraint plate 920, one end of the actuating rod 930 near the drive cam 910 abutting against the outer wall of the drive cam 910, a compression spring 940 fixedly connected between the end of the actuating rod 930 near the drive cam 910 and the constraint plate 920, and the end of the actuating rod 930 away from the drive cam 910 rotatably connected to a gear 950 via a rotating shaft 951, a toothed plate 960 meshing with the gear 950 fixedly connected to the outer wall of the mounting frame 810, and a second polishing brush fixedly connected to the end of the rotating shaft 951 away from the gear 950. 970, the third polishing brush 980 is fixedly connected to the side of the drive cam 910 away from the mounting frame 810 via a support rod.

Then, the third hydraulic cylinder 620 is turned on to extend it. The extension of the third hydraulic cylinder 620 causes the mounting seat 610 to move towards the lower shaping seat 20, thereby moving the first surface treatment mechanism 70 into the shaping groove at the top of the lower shaping seat 20. This causes the first polishing brush 730 to come into contact with the outer shell inside the shaping groove. At the same time, the electromagnet 820 is de-energized, the magnetic plate 860 separates from the electromagnet 820, and the rebound force of the torsion spring 850 causes the positioning block 830 to rotate out of the mounting frame 810, thereby...

Then, the drive shaft 710 is turned on, which drives the eccentric disk 720 to rotate, thereby driving the first grinding brush 730 to grind and polish the upper surface of the shell; at the same time, the drive cam 910 is turned on, which drives the third grinding brush 980 to rotate, realizing the grinding function of the areas that the two sets of first grinding brushes 730 cannot grind. During the rotation of the drive cam 910, the trigger rod 930 is driven to move back and forth, thereby driving The gear 950, rotatably connected to the actuating rod 930, reciprocates. The gear 950, via the rotating shaft 951, drives the second polishing brush 970 to reciprocate, further achieving the polishing function of areas that the two sets of first polishing brushes 730 cannot reach, while also increasing the polishing range of areas that the first polishing brushes 730 cannot contact. After the upper surface of the housing is polished, the electromagnet 820 is energized, and then the third hydraulic cylinder 620 is activated to retract, thereby driving the mounting base 610 and its connected first surface treatment mechanism 70 to move away from the lower shaping base 20. Then, through the adsorption mechanism 50, it connects with the upper shaping base 420 and... The bottom shaping module 430 has suction channels that attract the outer shell. Then, the second hydraulic cylinder 410 retracts to position it above the lower shaping seat 20. The telescopic adjustment mechanism 60 then extends, moving the first surface treatment mechanism 70 below the upper shaping seat 420. Simultaneously, the electromagnet 820 on the auxiliary positioning mechanism 80 is de-energized, thus positioning the outer shell attracted by the shaping module 430. The first and second surface treatment mechanisms 70 then treat the lower surface of the outer shell, combining pressure shaping with surface treatment of the car body, and simultaneously achieving the grinding and flipping function of the outer shell.

[0067] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A shaping device for the outer shell of a new energy vehicle is basically the same as that in Embodiment 1. Further, the adsorption mechanism 50 includes an L-shaped plate 510 fixedly installed on the outer wall of the upper shaping seat 420. A vacuum pump 520 is fixedly installed on the vertical section of the L-shaped plate 510. The output end of the vacuum pump 520 is connected to an adsorption channel located on the upper shaping seat 420. The end of the adsorption channel away from the vacuum pump 520 faces the lower shaping seat 20. After shaping, the vacuum pump 520 is turned on, generating negative pressure in the adsorption channel. This negative pressure then adsorbs the shaped car shell through the adsorption channel on the shaping module 430. The second hydraulic cylinder 410 is then controlled to contract, thus achieving the unloading function after pressure shaping. This solves the problem of the upper shaping seat 420 having only one function in the prior art.

9. The shaping method of a shaping device for a new energy vehicle shell as described in claim 8, characterized in that, Includes the following steps: S1: Place the car body to be shaped into the shaping groove on the lower shaping seat (20), then move the lower shaping seat (20) to the designated position and stop it, then open the first hydraulic cylinder (310) to extend it, thereby driving the constraint block (320) to engage with the positioning groove on the lower shaping seat (20), so that the lower shaping seat (20) is located directly below the upper shaping seat (420); S2: Then the second hydraulic cylinder (410) is opened to extend it, thereby driving the shaping module (430) at the bottom of the upper shaping seat (420) to pressurize and shape the shell in the shaping groove. After the shaping is completed, the vacuum pump (520) is turned on to generate negative pressure in the adsorption channel. Then the negative pressure generated by the adsorption channel on the shaping module (430) adsorbs the shaped car shell. Then the second hydraulic cylinder (410) is controlled to contract, thereby realizing the unloading function after pressurization and shaping, which solves the problem of the single function of the upper shaping seat (420) in the prior art. S3: After the pressure shaping is completed, the vacuum pump (520) is not turned on. Only the second hydraulic cylinder (410) is controlled to retract, driving the upper shaping seat (420) to move upward. Then the third hydraulic cylinder (620) is turned on to extend it. The extension of the third hydraulic cylinder (620) drives the mounting seat (610) to move towards the lower shaping seat (20), thereby driving the first surface treatment mechanism (70) to move into the shaping groove at the top of the lower shaping seat (20), so that the first polishing brush (730) abuts against the outer shell in the shaping groove. At the same time, the electromagnet (820) is de-energized. The magnetic plate (860) separates from the electromagnet (820), and the rebound force of the torsion spring (850) drives the positioning block (830) to rotate out of the mounting frame (810), thereby causing the positioning wheel (840) to abut against the outer shell under the torque of the torsion spring (850), realizing the auxiliary positioning function in the shell grinding process, realizing the combination of the grinding mechanism and the pressure shaping mechanism (40), and then the drive shaft (710) is turned on, the drive shaft (710) drives the eccentric disk (720) to rotate, thereby driving the first grinding brush (730) to grind and polish the upper surface of the shell; S4: Simultaneously activate the drive cam (910), which drives the third polishing brush (980) to rotate, thereby achieving the polishing function of areas that the two sets of first polishing brushes (730) cannot reach. During the rotation of the drive cam (910), the trigger rod (930) is driven to move back and forth, which in turn drives the gear (950) connected to the trigger rod (930) to rotate back and forth. The gear (950) drives the second polishing brush (970) to rotate back and forth through the rotating shaft (951), further achieving the polishing function of areas that the two sets of first polishing brushes (730) cannot reach, while increasing the polishing range of areas that the first polishing brushes (730) cannot reach. S5: After the upper surface of the outer shell is polished, the electromagnet (820) is energized, and then the third hydraulic cylinder (620) is opened to retract it, thereby driving the mounting base (610) and its connected first surface treatment mechanism (70) to move away from the lower shaping base (20). Then, the outer shell is attracted by the adsorption mechanism (50) and the adsorption channels on the upper shaping base (420) and the shaping module (430) at its bottom. Then, the second hydraulic cylinder (410) is retracted to place it on the upper surface of the lower shaping base (20). Then, the first surface treatment mechanism (70) is moved to the lower part of the upper shaping seat (420) by the extension adjustment mechanism (60), and the electromagnet (820) on the auxiliary positioning mechanism (80) is de-energized to realize the positioning function of the shell adsorbed by the shaping module (430). Then, the lower surface of the shell is treated by the first surface treatment mechanism (70) and the second surface treatment mechanism (90) to realize the combination of pressure shaping of the car shell and surface treatment of the shell, and at the same time realize the grinding and flipping function of the shell.
