Description

Technical Field

[0001] This utility model belongs to the field of stamping device technology, and in particular relates to an automated stamping device for household appliance hardware accessories. Background Technology

[0002] Hardware refers to parts processed from steel or some non-ferrous metals. Processing methods include cold / hot stamping, extrusion, rolling, welding, cutting, and many other processes; the definition is quite broad. Stamping is the most common type of hardware processing, referring to the shaping of sheet metal (steel / non-ferrous metals) into a specified form using molds and a press under the required pressure at room temperature. This includes some electronic components, automated home appliance parts, and decorative materials.

[0003] Patent application CN202420273883.2 discloses an automated stamping device for household appliance hardware accessories, including a base, a support frame welded to the upper surface of the base, a stamping cylinder mounted on the top of the support frame, a stamping head fixedly mounted on the telescopic end of the stamping cylinder, a mold seat fixedly mounted on the upper surface of the base, a stamping die inside the mold seat, a limit component on the side of the stamping die, and a cooling mechanism inside the mold seat. This utility model can fix the stamping die inside the mold seat through the limit component, preventing the stamping die from shifting during the stamping process and causing incorrect processing of hardware accessories. Moreover, by pressing the press rod, the movable plate and the clamping plate can be moved left and right. When the clamping plate disengages from the slot of the connecting plate, the mounting bracket can be removed, thereby removing the stamping die from the mold seat. Compared with the bolt fixing method, this application makes it more convenient to replace the stamping die, indirectly improving the stamping efficiency.

[0004] Existing technologies use cooling mechanisms to cool the mold, but these methods still have shortcomings: First, existing stamping equipment can only cool the bottom of the mold during operation, and cannot further cool the mold, nor can it cool the stamped parts and the stamping head, resulting in poor overall cooling effect of the equipment. Secondly, the existing stamping equipment lacks a buffering effect when stamping hardware parts, resulting in high noise during operation and significant wear and tear on some parts, thus affecting the service life of the equipment. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides an automated stamping device for household appliance hardware accessories. Through the design of structures such as a ring-shaped folding sealing sleeve, the low-temperature cooling air between the mold mounting frame and the sliding mounting plate is blown through multiple air outlets via the compression of the ring-shaped folding sealing sleeve. This allows the cooling air to reach the outer surface of the stamping head and the mold. Furthermore, the inclusion of components such as limiting rods ensures that both the stamping head and the stamping mold are buffered during the stamping process, effectively reducing the impact between them.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated stamping device for household appliance hardware accessories, comprising a workbench, a mold mounting frame on the upper surface of the workbench, a sliding mounting plate slidably disposed inside the mold mounting frame, a detachable mold on the upper surface of the sliding mounting plate, a cooling assembly disposed inside the mold mounting frame below the sliding mounting plate, an arc-shaped air guide groove disposed on each inner sidewall of the mold mounting frame outside the sliding mounting plate, a sliding plate slidably disposed above the mold, a stamping head slidably disposed below the sliding plate, an annular folding sealing sleeve connecting the sliding plate and the stamping head, a groove disposed on each sidewall of the stamping head, and multiple air outlet pipes communicating between each groove and the annular folding sealing sleeve.

[0007] Optionally, the annular folding sealing sleeve is provided with a plurality of limiting rods on the upper end face of the stamping head, each of the limiting rods being slidably connected to the sliding plate, and a first spring being provided on the outside of each limiting rod between the sliding plate and the stamping head.

[0008] Optionally, the lower end face of the stamping head is provided with a plurality of mating holes, and a mating rod is provided below each of the mating holes on the upper end face of the worktable, and each of the mating rods is slidably connected to the sliding mounting plate.

[0009] Optionally, the lower end face of the mold is provided with a plurality of limiting slide grooves, and one side wall of each limiting slide groove is provided with a snap-fit ​​groove. Below each snap-fit ​​groove, a slide groove is provided on the upper end face of the sliding mounting plate. A snap-fit ​​hook is slidably provided inside each slide groove, and the upper end of each snap-fit ​​hook is snap-fitted into the snap-fit ​​groove.

[0010] Optionally, a second spring is provided inside each of the slides between the slide and the snap hook.

[0011] Optionally, a movable push rod is slidably provided on one side of each of the snap hooks inside the mold mounting frame.

[0012] Optionally, a limit block is provided at one end of each of the movable ejector pins on one side of the mold mounting frame, and a third spring is provided on the outside of each of the movable ejector pins between the mold mounting frame and the limit block.

[0013] Optionally, a plurality of fourth springs are provided inside the mold mounting frame between the worktable and the sliding mounting plate.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model, through the setting of the annular folding sealing sleeve, the air outlet pipe and the arc-shaped air guide groove, enables the low-temperature cooling air to be blown between the mold mounting frame and the sliding mounting plate by squeezing the annular folding sealing sleeve and blowing through multiple air outlet pipes during the stamping process of the hardware parts. This allows the cooling air to be blown to the outer surface of the stamping head and the mold in the first time, thereby forming a cooling effect on the stamping mold and the stamping head, preventing the device from overheating and affecting the processing efficiency. (2) By setting up components such as the limiting rod, the first spring and the fourth spring, the present invention can buffer both the stamping head and the stamping die during the stamping process, thereby effectively reducing the impact between the die and the stamping head, and thus effectively reducing the noise during stamping and improving the service life of the device.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automated stamping device for household appliance hardware accessories includes a worktable 10. A mold mounting frame 11 is provided on the upper surface of the worktable 10. A sliding mounting plate 12 is slidably disposed inside the mold mounting frame 11. A plurality of fourth springs 35 are disposed inside the mold mounting frame 11 between the worktable 10 and the sliding mounting plate 12. When the stamping head 16 presses down on the mold 13 to perform the stamping operation, when vibration is generated during the stamping process, the fourth springs 35 can convert part of the vibration energy into elastic potential energy, thereby reducing the transmission of vibration and reducing the noise generated by vibration. This reduces the collision sound between the stamping head 16 and the mold 13, thereby improving the service life of the device. A detachable mold 13 is provided on the upper surface of the sliding mounting plate 12. A cooling assembly is disposed inside the mold mounting frame 11 below the sliding mounting plate 12. The cooling assembly includes components disposed on the worktable 10. The end face has a through hole 24, and a semiconductor cooling plate 25 is installed inside the through hole 24. A cooler 26 is connected below the semiconductor cooling plate 25. The cooler 26 is a common air cooler, which is existing technology. The cooler 26 cools the semiconductor cooling plate 25, thereby reducing the internal temperature of the mold mounting frame 11. The sliding mounting plate 12 can effectively cool the mold 13. The sliding mounting plate 12 has an arc-shaped air guide groove 27 on each inner side wall of the mold mounting frame 11. The arc-shaped air guide groove 27 is arc-shaped, and the top is provided with a slightly downward curved guide groove. When the air inside the annular folded sealing sleeve 17 is compressed and discharged through the air outlet pipe 19, the blown air can impact the inside of the arc-shaped air guide groove 27, thereby cooling the mold 13 and the stamping head 16 through the guiding effect of the arc-shaped air guide groove 27. A sliding plate 15 is slidably disposed above the mold 13, and a punch head 16 is slidably disposed below the sliding plate 15. An annular folding sealing sleeve 17 is connected between the sliding plate 15 and the punch head 16. The annular folding sealing sleeve 17 is configured so that when the punch head 16 moves downward to press down on the mold 13 and hardware accessories, the sliding plate 15 will further squeeze the annular folding sealing sleeve 17, causing the air inside the annular folding sealing sleeve 17 to be ejected through multiple air outlet pipes 19, thereby driving the flow of cold air between the mold mounting frame 11 and the sliding mounting plate 12, forming a subsequent cooling treatment for components such as the punch head 16. Each side wall of the punch head 16 is provided with a groove 18, and each groove 18 is provided with multiple air outlet pipes 19 that connect the groove 18 and the internal space of the annular folding sealing sleeve 17. A support frame 14 is provided above the sliding plate 15 on the upper end surface of the worktable 10. A stamping cylinder 22 is provided on the upper end surface of the support frame 14. The output end of the stamping cylinder 22 passes through the support frame 14 and is fixedly connected to the upper end surface of the sliding plate 15. The stamping cylinder 22 is a common electric cylinder or hydraulic cylinder, which is existing technology. The output end of the stamping cylinder 22 drives the sliding plate 15 and other components to move vertically. Multiple guide rods 23 are provided on the upper end surface of the sliding plate 15. All guide rods 23 are slidably connected to the support frame 14. The arrangement of multiple guide rods 23 forms a sliding guiding effect between the sliding plate 15 and the support frame 14, improving the accuracy of the device.

[0019] Furthermore, such as Figure 1 and Figure 4As shown, multiple limiting rods 20 are provided on the upper end face of the punch head 16 on the outside of the annular folding sealing sleeve 17. The limiting rods 20 guide the relative sliding between the punch head 16 and the sliding plate 15, and also limit the movement between the sliding plate 15 and the punch head 16. Each limiting rod 20 is slidably connected to the sliding plate 15. A first spring 21 is provided on the outside of each limiting rod 20 between the sliding plate 15 and the punch head 16. The elastic tension of the multiple first springs 21 is greater than the elastic tension of the multiple connecting rods 37. Therefore, when the sliding plate 15 drives the punch head 16 and other components to press down on the mold 13, the mold 13 and the sliding mounting plate 12 can be pressed down first until the sliding mounting plate 12 contacts the lower end face of the mold mounting frame 11. Then, the output end of the punching cylinder 22 drives the sliding plate 15. As it continues to move downwards, it compresses the multiple first springs 21 and the annular folding sealing sleeve 17, allowing the air inside the annular folding sealing sleeve 17 to be discharged from the multiple air outlet pipes 19 into the interior of the mold mounting frame 11. This causes the air inside the mold mounting frame 11 to cool down the components such as the stamping head 16. Simultaneously, when the stamping head 16 is lifted upwards after stamping, the large elastic tension of the multiple first springs 21 causes the sliding plate 15 to move upwards first. Then, the sliding plate 15 drives the components such as the stamping head 16 to move. During this process, the internal space of the annular folding sealing sleeve 17 increases, thus increasing the internal pressure. This allows the cold air inside the mold mounting frame 11 to be drawn into the annular folding sealing sleeve 17 through the multiple air outlet pipes 19, facilitating the cooling of the components such as the stamping head 16 during subsequent stamping.

[0020] Furthermore, such as Figure 4 As shown, the lower end face of the stamping head 16 is provided with a plurality of mating holes 36. Each mating hole 36 is provided with a mating rod 37 below the upper end face of the worktable 10. Each mating rod 37 is slidably connected to the sliding mounting plate 12. The mating rod 37 can limit the vertical movement of the sliding mounting plate 12, and at the same time, it can work with the mating holes 36 to provide a guiding function between the stamping head 16 and the die 13 during stamping, preventing the die 13 and the stamping head 16 from shifting during the stamping process, thereby improving the stamping accuracy.

[0021] Furthermore, such as Figure 3 and Figure 5As shown, the lower end face of the mold 13 is provided with multiple limiting slide grooves 38. Each limiting slide groove 38 has a snap-fit ​​groove 31 on one side wall. Below each snap-fit ​​groove 31, on the upper end face of the sliding mounting plate 12, there is a slide groove 28. Each slide groove 28 has a snap-fit ​​hook 29 slidably disposed inside. The upper end of each snap-fit ​​hook 29 is snap-fitted to the snap-fit ​​groove 31. The setting of components such as the snap-fit ​​groove 31 and the snap-fit ​​hook 29 facilitates the disassembly and installation of the mold 13. A second spring 30 is provided inside each slide groove 28 between the slide groove 28 and the snap-fit ​​hook 29. The setting of the second spring 30 facilitates the reset of the snap-fit ​​hook 29.

[0022] Furthermore, such as Figure 1 and Figure 5 As shown, a movable push rod 32 is slidably provided on one side of each snap hook 29 inside the mold mounting frame 11. A limit block 34 is provided at one end of each movable push rod 32 on one side of the mold mounting frame 11. A third spring 33 is provided between the mold mounting frame 11 and the limit block 34 on the outside of each movable push rod 32. The structure of the movable push rod 32, the third spring 33, and the limit block 34 allows the movable push rod 32 to support one side of the snap hook 29 when disassembling the mold 13. This causes the snap hook 29 to move horizontally, so that the top of the snap hook 29 disengages from the snap-fit ​​limit of the snap-fit ​​groove 31, thereby completing the disassembly of the mold 13.

[0023] When stamping the hardware parts, the cooler 26 and the stamping cylinder 22 are started first. The cooler 26 cools the air inside the mold mounting frame 11 through the semiconductor cooling plate 25. The output end of the stamping cylinder 22 drives the sliding plate 15 and the stamping head 16 and other components to stamp the hardware parts on the upper surface of the mold 13. During the stamping process, the air inside the annular folding sealing sleeve 17 is further compressed and blown into the mold mounting frame 11 through multiple air outlet pipes 19, thereby driving the cold air inside the mold mounting frame 11 to cool the components such as the stamping head 16.
