Description

Technical Field

[0002] Automotive refueling valves are key interface components in systems such as air conditioning, fuel, and lubrication, used to replenish liquids or gases. They are commonly used in scenarios involving the refueling of refrigerants, engine oil, grease, and fuel. They typically exist in the form of valves, ensuring a sealed, safe, and controllable refueling process. As a core component for fluid control, the valve body of an automotive refueling valve is often made from thin-walled stainless steel / aluminum alloy sheet through stamping, meeting stringent requirements such as multi-step cavities, high-precision sealing surfaces, burr-free inner walls, and no overall springback deformation.

[0003] Currently, existing stamping equipment for automotive filling valve bodies suffers from several drawbacks. In practical use, the feeding, delivery, and die structures are mostly independently designed, lacking collaborative operation capabilities. This results in poor blank positioning accuracy, easy disturbance of the blank during the push-back process, inability to automatically replenish material, and interruptions in the process due to the independent opening and closing of the die, making it difficult to improve stamping accuracy and production efficiency.

[0015] The beneficial effects of this invention are as follows: 1. This invention provides a precision stamping forming equipment for automotive filling valve bodies, comprising a feeding structure in which a blanking assembly, a pushing assembly, and a die assembly work together. The pushing assembly pushes the cylindrical blank provided by the blanking assembly to the die assembly. During this process, the pushing rod and the limiting frame of the pushing assembly can precisely limit the cylindrical blank to the stamping position at the die assembly, ensuring precision stamping forming.

A certain height is maintained to prevent the return stroke of the pusher assembly from affecting the accuracy of the blank position. At the same time, the inclined platform lifts the counterweight lifting frame and the stop plate to a certain height, removing the restriction on the position of the cylindrical blank, allowing the cylindrical blank to fall vertically onto the pusher rod.

[0016] 2. This invention provides a precision stamping forming equipment for automotive refueling valve bodies, integrating a polishing structure onto the stamping forming structure. This allows for immediate polishing after the blank stamping is completed, reducing subsequent polishing processes. The polishing components employ a combination of plug-in and elastic fixing designs.

[0022] In this embodiment, a feeding structure 4 is provided, in which the unloading component 41, the pushing component 42, and the mold component 43 work together. The pushing component 42 can push the cylindrical blank provided by the unloading component 41 to the mold component 43. During this process, the pushing rod 421 and the limiting frame 422 of the pushing component 42 can accurately limit the cylindrical blank to the stamping position of the mold component 43, ensuring precision stamping. When the cylindrical blank is in place, the L-shaped block 428 releases the restriction on the position of the positioning frame 426 under the action of the push plate 420, so that the first reset spring 424 stretches the positioning frame 426 to a certain height, thus avoiding When the pusher assembly 42 returns, it affects the accuracy of the blank position. At the same time, the inclined table 416 lifts the counterweight lifting frame 419 and the baffle plate 412 to a certain height, removing the restriction on the position of the cylindrical blank, so that the cylindrical blank can fall vertically onto the pusher rod 421. In this way, the pusher rod 421 can automatically fill the blank when it returns. When the pusher rod 421 returns, the positioning frame 426 and the baffle plate 412 will automatically return to their positions. Moreover, under the action of the toothed plate 433 and the spur gear 435, the bidirectional lead screw 436 is driven to rotate, thereby controlling the two guide blocks 437 to drive the mold body 430 to close the mold. The coordinated operation between the components of the feeding structure 4 can improve the stamping efficiency.

The guide block 437 is fixedly connected to the mold body 430, and the guide block 437 is slidably connected to the guide rail 432. The guide rail 432 is opened on the mold table 431. The mold table 431 is in contact with the valve body 3. When the toothed plate 433 is moved, the spur gear 435 can drive the bidirectional lead screw 436 to rotate, which in turn drives the two outer guide blocks 437 to drive the mold body 430 to close and open the mold.

[0025] like Figure 3 As shown, in this embodiment, preferably, the feeding assembly 41 includes a blank box 410, a feeding channel 411, a baffle plate 412, a baffle bar 413, a barrier plate 414, a feeding hopper 415, an inclined platform 416, a feeding pipe 417, a feeding support frame 418, and a counterweight lifting frame 419. The mold table 431 is fixedly connected to the feeding support frame 418, and the feeding support frame 418 is fixedly connected to the feeding hopper 415 through the feeding pipe 417. The feeding support frame 418 is also fixedly connected to the blank box 410. 0 is connected to the feeding channel 411, the feeding channel 411 is inserted into the baffle plate 412, the baffle plate 412 is fixedly connected to the counterweight lifting frame 419, the counterweight lifting frame 419 is inserted into the feeding support frame 418, the baffle plate 414 is fixedly connected to the feeding channel 411 through the baffle rod 413, when the inclined platform 416 moves, it can lift the counterweight lifting frame 419, drive the baffle plate 412 to a certain height, remove the restriction on the position of the cylindrical blank, and allow the cylindrical blank to fall smoothly onto the push rod 421.

[0026] like Figures 3-4 and Figure 6 As shown, in this embodiment, preferably, the pushing assembly 42 includes two push plates 420, a pushing rod 421, a limiting frame 422, and an electric telescopic rod 423.

The L-shaped block 428 is inserted into the positioning frame 426 and contacts the push plate 420. The push assembly 42 is used to feed the cylindrical blank. During this process, the push plate 420 can push the L-shaped block 428 away from the bottom of the fixed base 425. At this time, under the elastic pull of the first return spring 424, the positioning frame 426 will rise to a certain height and get rid of the restriction on the position of the cylindrical blank. It will not affect the return stroke of the push assembly 42. When the push assembly 42 returns to the position, the limiting frame 422 will press the positioning frame 426 down to the initial height. At the same time, under the elastic pull of the first return spring 424, the self-locking positioning frame 426 is realized.

[0027] Example 2: Figures 1-11 As shown, based on Embodiment 1, the present invention provides a technical solution: the polishing structure 2 includes a polishing component 21, a third hydraulic rod 22, a lifting plate 23, a motor 24, a drive gear 25, and a driven gear ring 26. The polishing component 21 is disposed outside the punch head 12, and the polishing component 21 is fixedly connected to the driven gear ring 26. The driven gear ring 26 meshes with the drive gear 25. The drive gear 25 is fixed on the output shaft of the motor 24. The motor 24 is fixedly connected to the lifting plate 23. The lifting plate 23 is fixedly connected to the output end of the third hydraulic rod 22. The third hydraulic rod 22 is fixedly connected to the lower pressure seat 13.

The cutting blade 213 and the polishing brush 214 are both located at the bottom of the slide 212. The movable plate 211 is fixedly connected to the driven toothed ring 26. The movable plate 211 includes a sleeve 2110 sleeved on the outside of the punch head 12. The polishing assembly 21 also includes a plug block 215, a connecting groove 218 and a connecting protrusion 219. The plug block 215 is plugged into the slide 212 and fixedly connected to the polishing brush 214. The connecting groove 218 is opened on the polishing brush 214.

The pin 217 is plugged into the slide 212 and the plug block 215.

[0028] In this embodiment, the polishing structure 2 is integrated onto the stamping structure 1, enabling immediate polishing after the blank stamping is completed. This reduces subsequent polishing processes. The polishing component 21 of the polishing structure 2 employs a combination of plug-in and elastic fixing design. The polishing brush 214 is plugged into the slide block 212 via a plug-in block 215. The pin 217, under the elastic action of the tension spring 216, can be quickly inserted into the slide block 212 and the plug-in block 215 for fixation. Disassembly is achieved simply by pulling the pin 217. Simultaneously, the cutting blade 213 is slidably connected to the connecting groove 218 of the polishing brush 214 via a connecting protrusion 219, allowing for flexible position adjustment according to processing requirements. This design allows the components of the polishing component 21 to be disassembled and replaced without the need for special tools, effectively shortening downtime for replacement after wear of the polishing components, improving the overall production efficiency of the valve body 3, and adapting to large-scale production needs.

[0029] The working principle of this invention is as follows: The billet box 410 pre-stores a certain amount of horizontally placed cylindrical billets. Under the action of gravity, the cylindrical billets will continuously roll into the feeding channel 411 for feeding the pusher assembly 42. In use, the cylindrical billets are placed vertically in the arc-shaped groove of the pusher rod 421, while the limiting frame 422 precisely limits the cylindrical billet. First, the electric telescopic rod 423 is activated, extending it to its maximum length to deliver the cylindrical blank to the stamping position. At this time, the push plate 420 pushes the L-shaped block 428 away from the bottom of the fixed seat 425. Under the elastic tension of the first return spring 424, the limit frame 422 rises above the cylindrical blank, freeing it from the restriction on the cylindrical blank's position. Simultaneously, the inclined platform 416 lifts the counterweight lifting frame 419 to a certain height, causing the baffle plate 412 to detach from the restriction on the position of the unloading channel 411. The cylindrical blank then slides to the outside of the unloading channel 411. Upon touching the baffle rod 413, it is adjusted to a vertical position and falls into the unloading hopper 415, sliding into the unloading pipe 417, with the bottom of the cylindrical blank contacting the baffle plate 412. Then, the first hydraulic rod 11 immediately shortens, controlling the push rod 421 to return. Under the action of gravity, the baffle plate 41... 2 will reset, blocking the cylindrical blank again. During this process, only one cylindrical blank falls to avoid blockage. After the push rod 421 returns to its original position, the limit frame 422 will press down and reset the positioning frame 426. Under the elastic tension of the second reset spring 429, the L-shaped block 428 will be stuck at the bottom of the fixed seat 425 again, fixing the positioning frame 426. At the same time, the cylindrical blank will fall into the arc groove of the push rod 421 and be limited by the positioning frame 426. Meanwhile, the push rod 421 drives the toothed plate 433 connected through the moving frame 434 to move, which drives the spur gear 435 to drive the bidirectional lead screw 436 to rotate, so that the two outer guide blocks 437 drive the mold body 430 to close the mold. The cylindrical blank is located in the two mold bodies 430. Finally, the first hydraulic rod 11 of the stamping forming structure 1 is activated, so that the stamping head 12 stamps the cylindrical blank into the valve body 3.

[0030] When polishing the outer side of the valve body 3, first control the pusher assembly 42 to return to the middle position, so that the two mold bodies 430 are separated and the sleeve 2110 is kept pressing the valve body 3. Then adjust the second hydraulic rod 210 to push the slide 212 to move, and adjust the working position of the cutting blade 213 and the polishing brush 214 to ensure that the polishing brush 214 is in close contact with the outer wall of the valve body 3. Finally, start the motor 24. The output shaft of the motor 24 drives the drive gear 25 to rotate. The drive gear 25 meshes with the driven gear ring 26 to drive the driven gear ring 26 to rotate at the bottom of the lifting plate 23, which in turn drives the polishing assembly 21 fixed with the driven gear ring 26 to rotate as a whole. During the rotation, the cutting blade 213 removes the excess blank material on the outer side of the valve body 3, and the polishing brush 214 simultaneously polishes the outer wall and the upper end surface of the valve body 3 to complete the processing and polishing of the excess material on the outside of the valve body 3. A blower can be added to the stamping worktable 15 to blow away excess material and prevent it from affecting the next use of each component. When the cutting blade 213 is worn or the polishing brush 214 is worn and needs to be replaced, first pull the pin 217 so that the pin 217 overcomes the elastic force of the tension spring 216 and disengages from the insertion engagement between the slide block 212 and the plug block 215. Then, directly pull the plug block 215 along with the polishing brush 214 out of the slide block 212. Next, slide the cutting blade 213 outward along the connecting groove 218 of the polishing brush 214 via the connecting protrusion 219. This completes the individual disassembly of the cutting blade 213. Subsequently, the polishing brush 214 and the cutting blade 213 can be replaced separately as needed. The operation is convenient and does not require special tools.
