Description

Technical Field

[0001] This invention relates to the field of stamping technology, specifically to an integrated stamping and finishing device for the integrated processing of acoustic enclosure shells. Background Technology

[0002] An acoustic package is a combination of materials, components, or systems used to control, optimize, or isolate sound. It is mainly used to reduce noise, improve sound quality, or achieve specific acoustic effects. Its shell is usually made of metal and is generally produced by stamping.

[0003] Because the surface of the acoustic package shell requires holes for installation and wiring, punching is necessary at the corresponding locations during production. Currently, after stamping, the formed product is typically placed into the next workstation for punching. Before punching, the acoustic package shell needs to be limited and fixed, making the process complex and significantly reducing production efficiency. While some equipment uses punching tools within the mold to complete punching simultaneously, the stamped product fits tightly to the mold, resulting in slight burrs at the punched holes. These burrs adhere to the punched areas on the mold, hindering subsequent demolding. Summary of the Invention

[0034] Please see Figures 1-12 The present invention provides a technical solution: an integrated stamping and trimming device for integrated processing of acoustic enclosure shell, including a base plate 1, a mold 2 and at least two molds 3 on the base plate 1, the mold 2 being fixedly connected to the base plate 1; the base plate 1 is provided with a driving mechanism for driving the molds 3 to close with the mold 2.

[0035] The mold 2 3 is equipped with a punching mechanism inside. The punching mechanism is used to punch several holes on the surface of the stamped acoustic package shell when the mold 2 3 and the mold 1 2 are closed.

[0036] The mold 1 2 is equipped with a demolding mechanism. The demolding mechanism is used to separate the part of the mold 2 3 located at the punching point from the acoustic package shell after the mold 2 3 has completed the stamping and punching of the acoustic package shell.

[0037] The demolding mechanism includes several sliding cavities 4 formed on the side wall of mold 2 3, each sliding cavity 4 corresponding to the position of the punched hole on the side of the acoustic package shell; a support block 5 is slidably connected in the sliding cavity 4, and punched cavities 6 are formed on the side wall of the support block 5 and the bottom of mold 2 3; a locking component is provided in the sliding cavity 4, which is used to fix the support block 5 in a position where its inner side is flush with the side wall of mold 2 3; an unlocking component is provided in the sliding cavity 4, which is used to unlock the support block 5 and drive the support block 5 to slide into the sliding cavity 4 when mold 2 3 and mold 1 2 are closed;

[0038] The base plate 1 is equipped with a trimming mechanism, which is used to trim and smooth the burrs at the punching positions on the surface of the acoustic package shell after it is demolded from the mold 2.

[0039] During operation, the raw material to be stamped is placed on mold 1 2, and then the drive mechanism is started. The drive mechanism drives mold 2 3 to move downward and close with mold 1 2. After the mold is closed, the acoustic package shell is stamped and formed. At this time, the punching mechanism can be started. Through the punching mechanism, multiple holes can be punched at specific positions on the stamped acoustic package shell.

[0040] During punching, the acoustic package shell protrudes outward at the hole location. Therefore, during demolding, the protruding part of the acoustic package shell at the hole location will get stuck in mold 2, making demolding difficult. At this time, the unlocking component is activated. The unlocking component unlocks the part of the mold 2 that is attached to the hole of the acoustic package shell and drives the part to separate from the acoustic package shell. At this time, the formed and punched acoustic package shell can be smoothly removed from mold 2, thereby realizing the integration of stamping and punching, and improving the production efficiency of acoustic package shells.

[0041] Place the detached acoustic package shell into the trimming position, and activate the trimming mechanism to trim and smooth the burrs on the protruding parts of the punched acoustic package shell.

[0042] As a further embodiment of the present invention, the punching mechanism includes a pressure plate 7 vertically slidably disposed within the mold 2 3, a plurality of cylinders 1 8 fixedly connected to the pressure plate 7, the telescopic ends of the cylinders 1 8 being fixedly connected to the mold 2 3; a plurality of pressure rods 1 9 and a pressure rod 2 10 fixedly connected to the bottom of the pressure plate 7; a plurality of punches 11 are slidably connected to the side wall and bottom of the punching part of the mold 2 3, and a connecting rod 12 is rotatably connected to one end of the punch 11 located inside the mold 2 3, the upper end of the connecting rod 12 being rotatably connected to the pressure rod 1 9; the upper end of the punch 11 at the bottom of the mold 2 3 is fixedly connected to the pressure rod 2 10;

[0043] The upper ends of the two connecting rods 12 connected to the two punches 11 arranged vertically on the side wall of mold 2 are both connected to the same pressure rod 9.

[0044] See during work Figure 4-6 When mold 2 (3) and mold 1 (2) are closed, the acoustic package shell is initially stamped and formed. At this time, multiple cylinders 1 (8) inside mold 2 (3) are activated. Cylinders 1 (8) drive the pressure plate 7 to move downward relative to mold 2 (3). The pressure plate 7 then drives multiple pressure rods 1 (9) and one pressure rod 2 (10) to move downward. When pressure rod 2 (10) moves downward, it drives multiple punches 11 at the bottom of mold 2 (3) to move downward. When the bottom punches 11 move downward, they punch corresponding holes on the bottom side of the acoustic package shell. When pressure rod 1 (9) moves downward, it drives the corresponding punches 11 to move outward through the connecting rod 12 connected to it. When the punches 11 move, they punch holes at corresponding positions on the side of the acoustic package shell. After punching is completed, cylinder 1 (8) is activated to reset the pressure plate 7. The pressure plate 7, through multiple pressure rods 1 (9) and one pressure rod 2 (10), can reset all the punches 11.

[0045] As a further embodiment of the present invention, the locking assembly includes four corner blocks 14 disposed in the slide cavity 4. The block 14 is slidably connected to the inner wall of the slide cavity 4 and is engaged with the support block 5. The block 14 is provided with a screw 15 threadedly connected to it. The screw 15 does not have self-locking properties and is rotatably connected to the inner wall of the slide cavity 4.

[0046] See during work Figure 7-8 Since the material being stamped needs to be fully supported by the inner wall of mold 1 2 and the outer surface of mold 2 3 during the stamping of the acoustic package shell, the four locking blocks 14 can provide strong support for the support block 5 in the slide cavity 4, so that the support block 5 can maintain sufficient extrusion pressure on the material during the stamping process.

[0047] As a further embodiment of the present invention, the unlocking component includes a slide groove 16 formed on both sides of the slide cavity 4 and penetrating the upper surface of the mold 2. A rack 17 is slidably connected in the slide groove 16. Gears 18 are meshed on both the upper and lower sides of the rack 17. The upper and lower gears 18 are fixedly connected to the lead screws 15 at the upper and lower positions, respectively. A spring 19 is fixedly connected to the rack 17. The bottom end of the spring 19 is fixedly connected to the inner wall of the slide groove 16. Springs 20 are fixedly connected to the four corner positions of the support block 5. The other end of the springs 20 is fixedly connected to the inner wall of the slide cavity 4. A pressing unit is provided inside the mold 2 3. The pressing unit is used to press all the racks 17 in the mold 2 downward when the mold 2 3 and the mold 2 2 are closed. A reset unit is provided at the bottom of the mold 2 3. The reset unit is used to drive the support block 5 in the slide cavity 4 to reset after the mold 2 3 is separated from the mold 2 2.

[0048] See during work Figure 4 , Figure 7-8 During punching, to prevent deformation of the acoustic package shell, a support plate supports the acoustic package shell at the punching point, ensuring that the acoustic package shell completes the punching process well. However, after punching, a slight deformation still occurs at the punching point, resulting in a slight outward protrusion of burrs. These burrs become stuck inside the punching cavity 6. At this point, a pressing mechanism presses all the racks 17 downwards. As the racks 17 move downwards, they drive the two gears meshing with them to rotate. The gears then drive the lead screw 15 to rotate. When it moves, it will drive the locking block 14 sleeved on its surface to move and disengage from the support block 5. When all the locking blocks 14 in the sliding cavity 4 are disengaged from the support block 5, under the action of the second spring 20, the support block 5 moves into the sliding cavity 4 and disengages from the acoustic package shell. At this time, the acoustic package shell can be smoothly separated from the mold 12. (The amount of shrinkage of the punch 11 can be controlled by multiple cylinders 18. The punch 11 can be controlled in the punch hole of the acoustic package shell. Then, by moving the mold 22 upward, the acoustic package shell is moved upward and the mold 22 is disengaged.)

[0049] As a further embodiment of the present invention, the pressing unit includes a number of pressing rods 21 equal to the number of racks 17, each pressing rod 21 being positioned directly above a rack 17; the pressing rods 21 are slidably connected to the mold 2 3 and the pressing rods 21 are entirely located inside the mold 2 3, with the upper end of the pressing rods 21 being fixedly connected to the pressing plate 7;

[0050] See during work Figure 4 When mold 23 and mold 12 are closed, several cylinders 18 are activated to move the pressure plate 7 downward. The pressure plate 7 will drive the pressure rod 19, multiple pressure rods 20 and multiple pressure rods 31 connected to it to move downward. While the pressure rod 19 and multiple pressure rods 20 drive multiple punches 11 to complete punching, the multiple pressure rods 321 just extend and fit against multiple racks 17. As the pressure plate 7 continues to move downward, the pressure rods 321 will begin to press the racks 17 they fit against downward.

[0051] As a further embodiment of the present invention, the reset unit includes a frame 22 that is vertically slidably mounted on the base plate 1. The frame 22 is fixedly connected to a plurality of inclined rods 23 at the bottom position of the mold 1 2. The number of inclined rods 23 is equal to the number of sliding cavities 4. A through hole 24 is provided above each inclined rod 23 at the bottom of the mold 1 2, which passes through the sliding cavity 4. The inclined rod 23 and the through hole 24 are fitted with a clearance fit. The upper part of the frame 22 is located above the mold 2 3.

[0052] See during work Figure 7-8 , Figure 10After the acoustic package shell is punched, the rack 17 moves downward, causing the locking block 14 to disengage from the support plate. At this time, under the action of the second spring 20, the support plate moves into the sliding cavity 4. This drives the second mold 3 to move upward, which in turn drives the acoustic package shell to move upward and separate from the first mold 2. When the acoustic package shell is completely separated from the first mold 2, the second mold 3 is just in contact with the upper part of the frame 22 and drives the frame 22 to move upward. The frame 22 will then drive the multiple inclined rods 23 at the bottom to move upward. The inclined rods 23 pass through the through hole 24 and move into the sliding cavity 4. 3. The inclined surface of the mold 22 is in contact with the support plate inside the sliding cavity 4. As the mold 22 moves upward, the support plate will gradually reset under the pressure of the inclined surface of the inclined rod 23. Since the lead screw 15 does not have self-locking properties, when the pressure rod 21 disengages from the rack 17, the rack 17 will automatically reset under the action of the spring 19, and the locking block 14 will also tend to reset automatically. When the support plate is fully reset, the support plate will no longer block the locking block 14. The locking block 14 and the rack 17 will reset under the action of the spring 19, and the locking block 14 will once again hold the support block 5 in place.

[0053] As a further embodiment of the present invention, the trimming mechanism includes a plurality of drive plates 25 mounted on the base plate 1. Both the drive plates 25 and the base plate 1 are equipped with telescopic shafts 26, and a grinding disc 27 is fixedly connected to the telescopic shaft 26. Each grinding disc 27 corresponds to the punching position of the acoustic package shell. The telescopic shaft 26 is an elastic telescopic shaft 26 and the edge of the grinding surface of the grinding disc 27 is an arc-shaped chamfer.

[0054] See during work Figure 10 After the formed acoustic package shell separates from the mold 2 3, the acoustic package shell is moved above the multiple polishing discs 27 by driving the mold 2 3, and then the acoustic package shell is driven to move downward. As the acoustic package shell moves downward, the polishing discs 27 will fit against the surface of the acoustic package shell. Since the edges of the polishing discs 27 are rounded and chamfered, when the protruding part of the punched part of the acoustic package shell moves to the position of fitting with the polishing disc 27, it will appropriately squeeze the polishing disc 27 outward along the edge of the polishing disc 27. When the acoustic package shell moves downward to the position of fitting with the bottom polishing disc 27, all the polishing discs 27 are fitted with the punched part on the acoustic package shell. Then, the polishing discs 27 are driven to rotate by the program-controlled drive plate 25, so that the protruding burrs on the punched part of the acoustic package shell can be polished and smoothed.

[0055] As a further embodiment of the present invention, the driving mechanism includes a second cylinder 28 fixedly connected to the base plate 1, a second gear 29 fixedly connected to the telescopic end of the second cylinder 28, a connecting plate 30 rotatably connected to the upper end of the second gear 29, the connecting plate 30 being fixedly connected to two molds 2 3 and a motor 31 fixedly connected to the connecting plate 30, and a third gear 32 fixedly connected to the bottom end of the output shaft of the motor 31, the third gear 32 meshing with the second gear 29;

[0056] See during work Figure 2-3 By starting cylinder 28, the connecting plate 30 can be moved up and down, and the connecting plate 30 can move the two molds 2 3 connected to it up and down to complete the stamping work; after the acoustic package shell is stamped, the starting motor 31 drives gear 32 to rotate, and gear 32 can drive the connecting plate 30 to rotate under the action of gear 29, and the connecting plate 30 will swap the positions of the two molds 2 3.
