Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a speaker basin frame welding piece stamping device. Background Art

[0002] The stamping device is a special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the required parts. Most of the welding pieces on the existing speaker basin frames are made by stamping devices.

[0003] For example, the patent number CN214601349U discloses a speaker basin frame welding piece punching device. Although the speaker basin frame welding piece punching device has a cleaning plate installed on the outer side of the top template of the stamping structure, when too much dust is left on the top of the cleaning plate, the personnel can remove the cleaning plate from the top of the stamping structure for cleaning. However, when the speaker basin frame welding piece punching device is actually used, it is necessary to pre-press several holes on the welding piece plate to be punched, place the welding piece plate on the top of the template so that the holes are aligned directly below the connecting rod, and move the connecting rod downward through the corresponding holes to achieve the fixation of the welding piece plate. With this fixing method, it is necessary to align the corresponding holes multiple times, resulting in cumbersome operations in fixing the welding piece plate, so it needs to be improved.

[0030] Among them, a plurality of punching grooves matching the corresponding punching heads 230 are evenly arranged on the upper end surface of the fixed mold 150. The sheet is placed on the upper end surface of the fixed mold 150. Through the setting of the driving assembly, the driving assembly can drive the limit plates 160 to approach each other, so as to clamp and fix the sheet placed on the fixed mold 150. At this time, the movable mold 130 is driven downward by the cylinder 120, so that the punching head 230 can abut the sheet and extend into the punching groove, so as to punch the sheet into a speaker basin frame welding piece;

[0031] The fixed die 150 is provided with a chamber 190 with a front opening, wherein the chamber 190 is connected to the stamping groove. Through the setting of the chamber 190, the speaker basin frame welding pieces after stamping fall into the chamber 190 for storage, so that it is convenient for operators to collect the speaker basin frame welding pieces after stamping;

[0032] Among them, by setting the driving assembly and the limiting plate 160, the driving assembly can drive the limiting plates 160 to approach each other, so that the sheet placed on the fixed mold 150 can be clamped and fixed. Compared with the existing positioning method, in this embodiment, there is no need to punch holes in the sheet, and the clamping and fixing process of the sheet on the fixed mold 150 is relatively simple and easy to operate;

[0033] By moving the limiting plates 160 closer to or farther from each other, the limiting plates 160 can clamp and fix sheets of different widths, thereby improving the applicability of the punching device.

[0034] In actual use, through the setting of the locking assembly, when the driving assembly drives the limit plates 160 to approach each other to clamp and fix the sheet on the fixed mold 150, the locking assembly can lock the driving assembly, thereby preventing the driving assembly from malfunctioning, causing the limit plates 160 to release the fixation of the sheet on the fixed mold 150, thereby affecting the stamping of the sheet on the fixed mold 150.

[0035] Combined with Figure 2-Figure 3 As shown, in this embodiment, a sliding groove 240 connecting to the installation cavity 270 is provided on the upper end surface of the base 100 along the moving direction of the limit plate 160, and the driving assembly includes a driving plate 310 arranged in the installation cavity 270, and the lower side surface of the driving plate 310 is provided with a sliding groove with a T-shaped cross section along its length direction, and a horizontal bar 250 is provided on the bottom wall of the installation cavity 270, and a T-shaped slider 260 adapted to the sliding groove is provided on the horizontal bar 250, and a slidable movable plate 210 is relatively provided on the bottom wall of the installation cavity 270, and the movable plate 210 is hingedly connected to the driving plate 310 through a hinge plate 300, and an L-shaped connecting plate 220 is provided on the movable plate 210, and the connecting plate 220 extends out of the sliding groove 240 and is connected to the corresponding limit plate 160.

[0036] In actual use of this embodiment, the horizontal bar block 250 is arranged at the center of the installation cavity 270 along the front-to-back direction of the base 100, and the movable plate 210 is parallel to the horizontal bar block 250, and the movable plate 210 is located on both sides of the horizontal bar block 250;

[0037] Among them, a limit block 330 with a T-shaped cross section is relatively provided on the lower side of the movable plate 210, and a limit groove 200 for the corresponding limit block 330 to slide into is provided on the bottom wall of the installation cavity 270 along the moving direction of the movable plate 210, thereby enabling the limit block 330 to be slidably installed in the limit groove 200, so that the movable plate 210 can be slidably installed on the bottom wall of the installation cavity 270, so that the movable plate 210 can move smoothly on the bottom wall of the installation cavity 270;

[0038] Among them, by sliding the driving plate 310 on the horizontal bar block 250, the driving plate 310 can slide to pull the hinge plate 300 to drive the moving plates 210 to move closer to or farther away from each other. Since the connecting plate 220 is used to connect the moving plate 210 and the limiting plate 160, the moving plates 210 can move closer to or farther away from each other, which can drive the limiting plate 160 to move closer to or farther away from each other, thereby achieving the clamping and fixing of the sheet material.

[0039] The sliding groove 240 is provided so that the connecting plate 220 can extend out of the mounting cavity 270 through the sliding groove 240 and be connected to the limiting plate 160, so that the connecting plate 220 can drive the limiting plate 160 to move closer to or farther from each other along the sliding groove 240;

[0040] The two ends of the hinged plate 300 are respectively hingedly mounted on the corresponding driving plate 310 and the moving plate 210 through mounting shafts, thereby realizing the hinged connection of the two ends of the hinged plate 300 .

[0041] Combined with Figure 3-Figure 4 As shown, in this embodiment, a driving block 400 is provided on the upper end surface of the driving plate 310, and a rotating rod 420 is provided in the installation cavity 270 along the sliding direction of the driving plate 310. One end of the rotating rod 420 extends through the side wall of the installation cavity 270, and the other end of the rotating rod 420 is provided with a threaded cavity, and a threaded rod 410 is threadedly installed in the threaded cavity. The threaded rod 410 is fixedly connected to the driving block 400, and rotating the rotating rod 420 is used to realize the sliding of the driving plate 310 on the horizontal bar block 250.

[0042] In actual use of this embodiment, one end of the threaded rod 410 is connected to the driving block 400 by welding, and the other end is threadedly connected to the threaded cavity, so that when the rotating rod 420 rotates, the threaded rod 410 is fixed and cannot rotate circumferentially, so that the rotation of the rotating rod 420 can drive the threaded rod 410 to extend and retract in the threaded cavity, thereby driving the driving plate 310 to slide on the horizontal bar block 250, thereby achieving the clamping and fixing and releasing of the sheet;

[0043] The rotating rod 420 extends from the front side of the base 100 , and a nut 140 is provided on the extended end of the rotating rod 420 . The nut 140 is provided to facilitate the operator to rotate the rotating rod 420 .

[0044] Combined with Figure 2-Figure 4 As shown, in the present embodiment, a plurality of snap-in grooves 180 are provided on the side surface of the protruding end of the rotating rod 420 along its axial direction; the locking assembly includes a fixing plate 170 fixedly arranged on the front side wall of the base 100, the protruding end of the rotating rod 420 passes through the fixing plate 170, a mounting groove 450 is provided on the upper end surface of the fixing plate 170, a locking rod 440 is provided in the mounting groove 450, the middle part of the locking rod 440 is rotatably installed in the mounting groove 450 through a hinge rod 500, one end of the locking rod 440 forms a snap-in portion 430, an elastic member is also provided in the mounting groove 450, the elastic member is used to abut against the other end of the locking rod 440 to realize the snap-in portion 430 being snapped into the snap-in groove 180.

[0045] In actual use, this embodiment is combined with Figure 5 As shown, the elastic member includes a mounting frame 520 fixed in the mounting groove 450, a spring 530 is sleeved on the mounting frame 520, and a column 560 is sleeved on the upper end of the spring 530, wherein the column 560 is short so that the column 560 can move up and down with the spring 530;

[0046] The other end of the locking rod 440 is bent to form a protruding portion 510, and the elastic member is located directly below the protruding portion 510, which is equivalent to lifting the protruding portion 510, that is, the spring 530 pushes the column 560 to abut against the lower side of the protruding portion 510, so that the protruding portion 510 tilts upward, and then the clamping portion 430 at one end of the locking rod 440 can move downward and extend into the clamping groove 180, so as to clamp and fix the rotating rod 420. Even if the rotating rod 420 is not easy to rotate, it is better to avoid the malfunction of the driving component caused by the malfunction of the rotating rod 420.

[0047] Among them, since the spring 530 is sleeved on the mounting frame 520, in actual use, the spring 530 is contracted by pressing the protrusion 510, so that the clamping portion 430 at one end of the locking rod 440 can be tilted up to disengage from the clamping groove 180, thereby releasing the fixing of the rotating rod 420. At this time, the rotating rod 420 can be rotated to achieve the mutual approach or distance between the limit plates 160.

[0048] Working principle: When it is necessary to perform stamping operation on the sheet, the sheet is placed on the upper end surface of the fixed mold 150, and the protrusion 510 of the locking rod 440 is pressed, so that the clamping portion 430 moves out of the clamping groove 180. At this time, the rotating rod 420 is rotated by the nut 140, so that the driving plate 310 can drive the hinge plate 300 to drive the moving plate 210 to move closer to each other, so that the moving plate 210 can drive the connecting plate 220 to drive the limiting plate 160 to move closer to each other, thereby clamping and fixing the sheet on the fixed mold 150. At this time, the pressing of the protrusion 510 is stopped, and the clamping portion 430 moves down. It extends into the snap-in groove 180 to snap-in and fix the rotating rod 420, and drives the punch head 230 to punch toward the fixed mold 150 through the movable mold 130, so that the punch head 230 abuts against the sheet and extends into the punching groove to complete the punching of the sheet. After the punching is completed, the speaker basin welding piece falls into the chamber 190 for storage; at this time, the movable mold 130 drives the punch head 230 to rise, presses the protrusion 510, so that the snap-in portion 430 is moved out of the snap-in groove 180, and the nut 140 is rotated in the opposite direction, so that the driving assembly can drive the limit plates 160 to move away from each other, thereby releasing the fixation of the sheet on the fixed mold 150.

[0049] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
