In an efficient method for processing and manufacturing sound-absorbing panels, a punching die for punching includes a detection device, an adjustment device, and a driving device. First, an aluminum plate is fixed on a fixed seat, and a detection component detects the width of the aluminum plate. The adjustment component is arranged between the punch and the push plate, and the adjustment component is connected to the detection component in a transmission manner.

Description

Technical Field

[0002] In the manufacturing process of aluminum perforated plates, it is necessary to regularly punch holes in the aluminum plate and leave a frame at the edge so that the aluminum plate can be folded later. In the existing process of punching holes in metal plates, a mechanical punch is usually used to punch holes in the metal plate. However, when a conventional mechanical punch punches holes in an aluminum plate, the mechanical punch punches evenly on the surface of the metal plate, which is easy to punch incomplete holes at the edge of the metal plate, and it is difficult to control the reservation of the metal plate frame. When punching the aluminum plate, if there is no regular frame, it is difficult to fold the aluminum plate later. At the same time, the existing mechanical punch controls the spacing between the holes through the operator, which reduces the accuracy of the holes on the aluminum plate. Summary of the invention

[0033] An embodiment of an efficient sound-absorbing panel manufacturing method of the present invention includes the following steps: Step S10, fixing the workpiece to be processed. Step S20, punching the workpiece using a stamping die. Step S30, taking out the processed workpiece.

[0034] In this embodiment, if Figures 1 to 8 As shown, the stamping die in step S20 includes a fixing seat 100, a fixing frame 110, a pushing plate 120, a detection device, a punch 400, an adjustment device, a driving device and a limit assembly. The fixing seat 100 is arranged horizontally, and at least four legs are arranged at the lower end of the fixing seat 100. The legs are retractable and used to adjust the height of the fixing seat 100. At the same time, the fixing seat 100 can be leveled according to the flatness of the ground.

[0035] The fixing frame 110 is bent so that the fixing frame 110 has a cross bar parallel to the fixing seat 100, and the cross bar is arranged above the fixing seat 100. The fixing frame 110 has a vertical bar arranged perpendicular to the cross bar, and the lower end of the vertical bar is fixedly arranged on the side wall of the fixing seat 100, so that the cross bar remains stable above the fixing seat 100.

[0036] The push plate 120 is arranged horizontally, and the lower end surface of the push plate 120 is provided with a first guide groove along the length direction of the push plate 120. A driving device is arranged between the push plate 120 and the cross bar, and the driving device includes a push rod and a hydraulic rod 710. The hydraulic rod 710 has a force to make the push plate 120 slide up and down, so that the push plate 120 slides up and down above the aluminum plate. The push rod has a force to intermittently make the push plate 120 slide along the cross bar. When the hydraulic rod 710 completes a set of reciprocating up and down motions, the push rod prompts the push rod to move a preset distance along the cross bar.

[0037] There are multiple groups of punches 400 , which are fixedly disposed below the push plate 120 and evenly arranged along the length direction of the push plate 120 , so that the punches 400 can punch holes in the aluminum plate when the push plate 120 slides along the fixing frame 110 .

[0038] The detection device includes a first detection plate 210 and a second detection plate 220. The first detection plate 210 and the second detection plate 220 can be retracted and arranged. The first detection plate 210 and the second detection plate 220 are arranged vertically. The upper ends of the first detection plate 210 and the second detection plate 220 can be slidably arranged in the first guide groove, and the lower ends of the first detection plate 210 and the second detection plate 220 are both abutted against the upper end of the fixed seat 100. The first detection plate 210 and the second detection plate 220 are spaced apart from the two ends of the push plate 120, and a first elastic member is provided between the first detection plate 210 and the second detection plate 220. The first elastic member has the tendency to drive the first detection plate 210 and the second detection plate 220 to approach each other or have such movement. Specifically, the first elastic member is a first spring, and the first spring has a preset pulling force, so that when an aluminum plate with a certain width is provided between the first detection plate 210 and the second detection plate 220, the first detection plate 210 and the second detection plate 220 quickly abut against the aluminum plate under the action of the first spring, and when the first detection plate 210 and the second detection plate 220 abut against the aluminum plate, the sliding of the first detection plate 210 and the second detection plate 220 is hindered.

[0039] The adjustment device includes at least one group of adjustment components, and two adjacent adjustment components are fixedly connected. Multiple groups of adjustment components are arranged between the first detection plate 210 and the second detection plate 220. The number of adjustment components can be manually adjusted according to the width of the aluminum plate to improve the applicability to aluminum plates of different widths.

[0040] In this embodiment, each adjustment assembly includes two fixed blocks 310, two sliding blocks 320 and a rotating block 330. The two fixed blocks 310 are arranged at intervals. A fixed rod 530 is fixedly arranged on the upper end of each fixed block 310. The fixed rod 530 is arranged vertically. The upper end of the fixed rod 530 is slidably arranged in the first guide groove so that the fixed block 310 can slide along the direction of the first guide groove. The two fixed blocks 310 are fixedly connected to the first detection plate 210 and the second detection plate 220 respectively, so that the two fixed blocks 310 are close to each other under the action of the first spring between the first detection plate 210 and the second detection plate 220. The fixed block 310 is an isosceles trapezoidal structure. The adjustment assemblies of two adjacent groups share the same fixed block 310. The lower end surface of the fixed block 310 is fixedly provided with a punch 400.

[0041] A third guide groove is provided at the lower end of the push plate 120, and the third guide groove is arranged parallel to the first guide groove. Two sliding blocks 320 are arranged at intervals, and a first guide rod 510 is arranged above the two sliding blocks 320, and the first guide rod 510 can slide left and right along the third guide groove. A guide block 322 is fixedly arranged on the upper end surface of each sliding block 320, and the guide block 322 can slide up and down along the first guide rod 510, so that the sliding block 320 can slide up and down along the first guide rod 510 and can slide along the third guide groove. The sliding block 320 is an isosceles trapezoidal structure, and the sliding block 320 and the fixed block 310 are arranged in the opposite direction, so that the inclined surface of the sliding block 320 contacts the inclined surface of the fixed block 310, which is the first state in which the sliding block 320 and the fixed block 310 are in contact. When the two fixed blocks 310 are close to each other, the two sliding blocks 320 are gradually squeezed to slide upward along the first guide rod 510, so that the inclined surface of the sliding block 320 and the inclined surface of the fixed block 310 are gradually out of contact, which is the second state in which the sliding block 320 and the fixed block 310 are not in contact. A punch 400 is fixedly arranged on the lower end surface of the sliding block 320.

[0042] The rotating block 330 includes a first rotating part 331, a second rotating part 332, a third rotating part 333 and a rotating shaft 334. The first rotating part 331 and the third rotating part 333 are of right-angled trapezoidal structure, the second rotating part 332 is of rectangular structure, the first rotating part 331 and the second rotating part 332 are fixedly connected with the second rotating part 332 and the third rotating part 333 through the rotating shaft 334, so that the rotating block 330 forms an isosceles trapezoidal structure. The rotating block 330 of the isosceles trapezoidal structure is initially arranged between the two sliding blocks 320, and the inclined surfaces of the first rotating part 331 and the third rotating part 333 are respectively in contact with the inclined surfaces of the two sliding blocks 320. A connecting rod 520 is arranged between the rotating shaft 334 and the pushing plate 120, the connecting rod 520 is rotatably connected to the rotating shaft 334, and the connecting rod 520 is telescopically arranged. The transmission rod 540 is bent, one end of the transmission rod 540 is fixedly connected to the sliding block 320, and the other end is in contact with the rotating shaft 334, so that when the sliding block 320 slides upward along the first guide rod 510 and the sliding block 320 and the fixed block 310 are in the second state, the rotating shaft 334 is gradually rotated to drive the first rotating part 331, the second rotating part 332 and the third rotating part 333 to rotate, and under the action of the first spring, the inclined surfaces of the first rotating part 331 and the third rotating part 333 are in contact with the inclined surface of the fixed block 310. Punches 400 are provided at both upper and lower ends of the second rotating part 332 to increase the applicability of punching holes in aluminum plates of different widths.

[0043] In this embodiment, the punch 400 includes a fixed portion 401 and a sliding portion 402. The fixed portion 401 is hollow inside, and the upper end of the fixed portion 401 is fixedly disposed on the sliding block 320, the fixed block 310, and the second rotating portion 332. One end of the sliding portion 402 is slidably disposed in the fixed portion 401, and a second elastic member is fixedly disposed between the sliding portion 402 and the fixed portion 401. The second elastic member is a second spring, so that when the sliding portion 402 completely slides into the fixed portion 401, the lower end of the fixed portion 401 punches the workpiece. When the sliding portion 402 slides along the fixed portion 401, the relative position between the fixed block 310 and the sliding block 320 or the rotating block 330 is fixed by a limiting assembly, so as to prevent the relative sliding between the fixed block 310 and the sliding block 320 or the rotating block 330 when punching the aluminum plate.

[0044] The limiting assembly includes a driving unit and a limiting plate 630. A plurality of first limiting grooves 321 are provided on the inclined surface of the sliding block 320, a plurality of second limiting grooves are provided on the inclined surface of the first rotating portion 331, and a plurality of third limiting grooves 3331 are provided on the inclined surface of the second rotating portion 332. The limiting plate 630 is horizontally arranged and slidably arranged inside the fixed block 310. When the limiting plate 630 slides, the limiting plate 630 can slide out from the side wall of the fixed block 310 and can slide into the first limiting groove 321 or the second limiting groove or the third limiting groove 3331. When the limiting plate 630 extends from the inside of the fixed block 310, it hinders the sliding between the fixed block 310 and the sliding block 320 or the fixed block 310 and the rotating block 330. The driving unit includes a driving rod 610 and a fixed wheel 620. The driving rod 610 is slidably disposed inside the fixed block 310, and one end of the driving rod 610 is fixedly connected to the sliding portion 402 of the punch 400. The fixed wheel 620 is rotatably disposed inside the fixed block 310, and is frictionally connected to the driving rod 610, so that when the sliding portion 402 of the punch 400 slides along the fixed portion 401, the driving rod 610 slides and drives the fixed wheel 620 to rotate. The limiting plate 630 is frictionally connected to the fixed wheel 620, so that when the fixed wheel 620 rotates, the limiting plate 630 extends out of the fixed block 310, thereby fixing the positions among the fixed block 310, the sliding block 320 and the rotating block 330.

[0045] In this embodiment, the first guide rod 510 is provided with a second guide groove 511, the second guide groove 511 has a folded angle, the widths of the upper and lower ends of the second guide groove 511 are consistent, and the middle part of the second guide groove 511 has a folded angle. The guide block 322 is provided with a third elastic member at both ends, and the third elastic member is a telescopic spring plate 323. When the guide block 322 slides along the second guide groove 511, the telescopic spring plate 323 is first compressed. After the telescopic spring plate 323 passes through the folded angle, the telescopic plate is quickly moved up along the second guide groove 511, so that the sliding block 320 is out of contact with the fixed block 310, and the transmission rod 540 is pulled to move upward quickly to drive the rotating shaft 334 to rotate, and the first rotating part 331 and the second rotating part 332 are rotated 180 degrees. Under the action of the first spring, the fixed block 310 is in contact with the rotating block 330.

[0046] In combination with the above embodiments, the use principle and working process of the stamping die in the embodiment of the present invention are as follows:

[0047] During operation, the aluminum plate to be processed is fixed on the upper end of the fixing seat 100. After the first detection plate 210 and the second detection plate 220 are close to each other and abut against the aluminum plate, the hydraulic rod 710 and the push rod are started to evenly punch holes in the aluminum plate.

[0048] When punching aluminum plates of different widths, the first detection plate 210 and the second detection plate 220 begin to approach each other under the action of the first spring, and the sliding block 320 slides upward along the first guide rod 510 under the squeezing action of the fixed blocks 310 at both ends. Figure 7 In the state shown, when processing a wider aluminum plate, the guide block 322 at the upper end of the sliding block 320 does not cross the angle of the second guide groove 511 when sliding along the first guide rod 510. Under the action of the hydraulic rod 710, the push plate 120 slides downward, and the sliding portion 402 of the punch 400 gradually slides toward the inside of the fixed portion 401, driving the drive rod 610 to slide in the fixed block 310. The drive rod 610 drives the fixed wheel 620 to rotate, and the limiting plate 630 frictionally transmitted with the fixed wheel 620 slides inside the fixed block 310 and gradually extends out of the fixed block 310 and is inserted into the first limiting groove 321, limiting the position between the fixed block 310 and the sliding block 320, so that the sliding block 320 cannot slide upward along the first guide rod 510. Under the joint action of the two fixed sliding blocks 320, the rotating block 330 cannot slide and cannot rotate. Under the action of the pushing plate 120 , the sliding portion 402 of the punch 400 completely slides into the interior of the fixing portion 401 . As the pushing plate 120 continues to slide downward, the fixing portion 401 of the punch 400 punches a hole in the aluminum plate.

[0049] like Figure 8In the state shown, when the width of the aluminum plate to be processed is narrow, the guide block 322 at the upper end of the sliding block 320 slides along the first guide rod 510 and passes over the angle of the second guide groove 511. The telescopic spring plate 323 between the guide block 322 and the second guide groove 511 quickly slides upward along the second guide groove 511 under the action of resetting, so that the fixed block 310 and the sliding block 320 are out of contact. Since the upper end of the sliding block 320 is fixedly connected to the transmission rod 540, the transmission rod 540 is driven and is in contact with the sliding block 320. 20 slides upward synchronously and quickly. Due to the friction transmission between the side wall of the transmission rod 540 and the rotating shaft 334, when the transmission rod 540 moves upward quickly, the rotating shaft 334 rotates 180 degrees, so that the first rotating part 331, the second rotating part 332 and the third rotating part 333 of the rotating block 330 are reversed. At this time, under the action of the first spring, the inclined surfaces of the two fixed blocks 310 are respectively abutted against the inclined surfaces of the first rotating part 331 and the second rotating part 332, and the number of holes punched in the aluminum plate is reduced. If the first detection plate 210 and the second detection plate 220 are in contact with the aluminum plate at this time, under the push of the pushing plate 120, the sliding part 402 of the punch 400 is in contact with the upper end surface of the aluminum plate. As the pushing plate 120 continues to push downward, the limiting plate 630 inside the fixed block 310 gradually extends out, and the limiting plate 630 is gradually inserted into the second limiting groove and the third limiting groove 3331 to fix the positions of the first rotating part 331, the second rotating part 332, and the third rotating part 333 with the two fixed blocks 310. After the sliding part 402 of the punch 400 gradually slides into the fixed part 401, the pushing plate 120 pushes the fixed part 401 of the punch 400 to punch the aluminum plate. If the first detection plate 210 and the second detection plate 220 are not in contact with the aluminum plate at this time, since a connecting rod 520 is provided between the rotating shaft 334 of the rotating block 330 and the pushing plate 120, and the connecting rod 520 is retractable, under the action of the first spring, the two fixed blocks 310 simultaneously squeeze the first rotating part 331 and the second rotating part 332 of the rotating block 330, so that the connecting rod 520 contracts and the first rotating part 331 and the second rotating part 332 slide further upward. After the first detection plate 210 and the second detection plate 220 are in contact with the aluminum plate, the pushing plate 120 120 pushes the sliding part 402 of the punch 400 to move downward and gradually contacts the upper end surface of the aluminum plate. As the pushing plate 120 continues to push downward, the limiting plate 630 in the fixed block 310 is gradually inserted into the second limiting groove and the third limiting groove 3331 to fix the positions of the first rotating part 331, the second rotating part 332, and the third rotating part 333 with the two fixed blocks 310. After the sliding part 402 of the punch 400 gradually slides into the fixed part 401, the pushing plate 120 pushes the fixed part 401 of the punch 400 to punch the aluminum plate.

[0050] By punching aluminum plates of different widths, the use range of the stamping die is increased.
