Description

Technical Field

[0001] This application relates to the field of equipment technology for manufacturing washing machine parts, and in particular to a stamping machine for washing machine parts. Background Technology

[0002] With the rapid development of the home appliance manufacturing industry, the market has placed higher demands on the quality and production efficiency of home appliances. Especially in the manufacturing process of washing machine parts, traditional manual or semi-automatic production equipment can no longer meet the current market's high-volume demands, and it is also difficult to guarantee the stability of product quality.

[0003] In the production of washing machine parts, a stamping machine is required. Chinese utility model patent CN221754503U discloses a stamping die for producing a washing machine front cover. It includes an upper die, a lower die below the upper die, a support plate above the upper die, a cylinder above the support plate, two symmetrical support columns between the support plate and the lower die, a through groove in the middle of the support plate, a control panel on the side of the lower die away from the support columns, movable grooves on both sides of the upper surface of the lower die, a fixing device above the movable grooves, a first connecting plate at one end of the lower die, a second connecting plate above the first connecting plate, a clamping device on the side of the second connecting plate near the lower die, an annular groove on the upper surface of the lower die, a square groove at the bottom of the annular groove, a cylindrical groove below the square groove, and a lifting device below the cylindrical groove. This utility model allows for clamping and loading / unloading of the front cover to be stamped, eliminating the need for manual placement of the raw material onto the stamping die.

[0004] In the process of implementing this application, the technology has at least the following problems. In the actual production process of washing machine parts, continuous processing of the parts is required. However, the clamping device can only achieve the effect of unloading and cannot achieve continuous loading and unloading, which affects the production efficiency. Therefore, a washing machine parts stamping machine is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a stamping machine for washing machine parts, which has the advantage of easy loading and unloading. This solves the problem that in the actual production process of washing machine parts, continuous processing of the parts is required, but the clamping device can only achieve the unloading effect and cannot achieve continuous loading and unloading, thus affecting production efficiency.

[0006] In summary, this application provides the following technical solution: a stamping machine for washing machine accessories, including a worktable and a support frame fixedly connected to the back of the top of the worktable, a drive box extending to the top of the worktable fixedly connected to the front of the worktable, and a loading and unloading mechanism extending to the outside of the drive box.

[0007] The loading and unloading mechanism includes a drive motor fixedly installed inside the drive box, a transmission gear fixedly connected to the output shaft of the drive motor, a movable rack slidably connected inside the drive box and extending to its outside, a mounting plate fixedly connected to the back of the movable rack, a connecting plate fixedly connected to the back of the mounting plate, an electric push rod fixedly installed on the top of the connecting plate and extending to its bottom, and a pneumatic suction cup fixedly installed on the output end of the electric push rod. The movable rack meshes with the transmission gear.

[0008] This application adopts the above-mentioned technical solution, which sets a drive motor to drive the transmission gear to rotate, and then the transmission gear drives the moving rack to move laterally, so that the moving rack can drive the mounting plate to move. By setting an electric push rod to drive the pneumatic suction cup to move downward, the washing machine parts inside the storage box can be adsorbed and fixed. In conjunction with the transmission gear, the washing machine parts can be easily transported to the worktable, thus achieving the effect of synchronous loading and unloading, eliminating the need for manual loading by staff and improving production efficiency.

[0009] Furthermore, there are two connecting plates, which are symmetrically distributed on the back of the mounting plate. The mounting plate is located on the back of the drive box and is slidably connected to it.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting two connecting rods, it is possible to achieve the effect of simultaneous movement of two electric push rods and pneumatic suction cups, thus achieving synchronous loading and unloading.

[0011] Furthermore, a storage box is fixedly installed on one side of the workbench, a push plate is slidably connected inside the storage box, an installation sleeve is fixedly connected to the inner bottom wall of the storage box, an elastic movable rod extending into the installation sleeve is fixedly connected to the bottom of the push plate, and a return spring is fixedly connected between the elastic movable rod and the installation sleeve.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting a return spring and an elastic movable rod, when the staff puts the washing machine parts into the storage box, it will squeeze the push plate, which will cause the return spring to compress. When the washing machine parts are taken out one by one, the return spring can rebound due to the decrease in weight, which will drive the washing machine parts to move upward, making it easier to take out the washing machine parts.

[0013] Furthermore, there are two storage boxes, which are symmetrically distributed on the left and right sides of the workbench. Each storage box is a hollow, lidless cuboid.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting up two storage boxes, it is possible to achieve the effect of feeding and discharging materials at the same time.

[0015] Furthermore, a hydraulic cylinder extending to the bottom of the support frame is fixedly installed on the top of the support frame, and a lifting plate is fixedly connected to the output end of the hydraulic cylinder. An upper mold is fixedly connected to the side of the lifting plate near the workbench, and a lower mold adapted to the upper mold is fixedly installed on the upper surface of the workbench.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting a hydraulic cylinder to drive the upper mold to move downward, and by setting a lower mold, it is convenient to stamp the washing machine parts.

[0017] Furthermore, the pneumatic suction cup is located on the horizontal center line of the lower mold, and the upper mold is located directly above the lower mold.

[0018] The advantage of adopting the above-mentioned further solution is that, since the pneumatic suction cup is located at the center of the lower mold, it is easier to remove the washing machine parts from the lower mold.

[0019] Furthermore, a positioning guide rod that penetrates the lifting plate is fixedly connected to the bottom of the support frame, and a clamping block is fixedly connected to one end of the positioning guide rod near the lower mold. A support spring is fixedly connected between the clamping block and the lifting plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by setting a hydraulic cylinder to drive the lifting plate to move downward, the lifting plate simultaneously drives the pressing block to move downward, thereby enabling the pressing block to contact the washing machine parts first, thus achieving the effect of pressing and positioning the washing machine parts.

[0021] Furthermore, the positioning guide rod and the lifting plate are connected by a sliding connection, and the support spring is sleeved on the outside of the positioning guide rod.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the compression of the support spring by the lifting plate and the pressing block, so that the support spring can generate a reaction force on the washing machine accessories.

[0023] Compared with the prior art, this application provides a stamping machine for washing machine parts, which has the following advantages:

[0024] 1. This washing machine parts stamping machine uses a drive motor to rotate a transmission gear, which in turn drives a moving rack to move laterally. This allows the moving rack to move a mounting plate. An electric push rod moves a pneumatic suction cup downwards, which then adsorbs and fixes the washing machine parts inside the storage box. Combined with the transmission gear, this facilitates the transport of the washing machine parts to the worktable, achieving synchronous loading and unloading without the need for manual loading by staff, thus improving production efficiency.

[0025] 2. This washing machine parts stamping machine uses a hydraulic cylinder to move a lifting plate downwards. Simultaneously, the lifting plate moves a pressing block downwards, allowing the pressing block to preferentially contact the washing machine parts. This achieves the effect of pressing and positioning the washing machine parts. Subsequently, the upper mold moves downwards to stamp the washing machine parts, facilitating their positioning and preventing displacement during stamping. This solves the problem that in the actual production process of washing machine parts, continuous processing of parts is required, but the clamping device can only perform unloading, not continuous loading and unloading, thus affecting production efficiency.

[0034] Please see Figures 1 to 3This embodiment of a washing machine accessory stamping machine includes a workbench 1 and a support frame 2 fixedly connected to the top back of the workbench 1. A drive box 3 extending to the top of the workbench 1 is fixedly connected to the front of the workbench 1. The drive box 3 is provided with a loading and unloading mechanism extending to the outside. The loading and unloading mechanism includes a drive motor 4 fixedly installed inside the drive box 3, a transmission gear 5 fixedly connected to the output shaft of the drive motor 4, a movable rack 6 slidably connected inside the drive box 3 and extending to the outside, a mounting plate 7 fixedly connected to the back of the movable rack 6, a connecting plate 8 fixedly connected to the back of the mounting plate 7, an electric push rod 9 fixedly installed on the top of the connecting plate 8 and extending to the bottom of the connecting plate 8, and a pneumatic suction cup 10 fixedly installed on the output end of the electric push rod 9. The movable rack 6 meshes with the transmission gear 5.

[0035] There are two connecting plates 8, which are symmetrically distributed on the back of the mounting plate 7. The mounting plate 7 is located on the back of the drive box 3 and is slidably connected to it. By setting two connecting rods 8, the two electric push rods 9 and the pneumatic suction cup 10 can move simultaneously, so as to achieve synchronous loading and unloading.

[0036] It should be noted that a PLC controller is fixedly installed on the front of the workbench 1. The number of rotations of the drive motor 4 driving the transmission gear 5 is precisely controlled by the PLC controller, thereby accurately controlling the moving distance of the mounting plate 7 and improving the accuracy of loading and unloading. A suction device adapted to the pneumatic suction cup 10 is fixedly installed on the back of the workbench 1. By setting the drive motor 4 to drive the transmission gear 5 to rotate, and then the transmission gear 5 to drive the moving rack 6 to move laterally, the moving rack 6 can drive the mounting plate 7 to move. By setting the electric push rod 9 to drive the pneumatic suction cup 10 to move downward, the washing machine parts inside the storage box 11 can be suctioned and fixed. With the help of the transmission gear 5, the washing machine parts can be easily transported to the workbench 1, thereby achieving the effect of synchronous loading and unloading, eliminating the need for manual loading by the staff and improving production efficiency.

[0037] In addition, the PIC controller outputs digital signals from designated pins through its internal program logic. These digital signals are typically high-level (e.g., 5V or 3.3V, depending on the PIC controller's power supply voltage) and low-level (0V); motor drivers (such as H-bridge drivers for DC motors) usually require these digital input signals to control the motor's operation; the PIC controller sends control commands (such as forward / reverse rotation, speed setting, etc.) to the motor driver in the form of digital signals or PWM signals according to a pre-programmed program. After receiving these commands, the motor driver's internal power electronics (such as MOSFETs or IGBTs) perform corresponding switching actions according to the commands.

[0038] Please see Figure 2 and Figure 4 In this embodiment, a storage box 11 is fixedly installed on one side of the workbench 1. A push plate 15 is slidably connected inside the storage box 11. An installation sleeve 12 is fixedly connected to the inner bottom wall of the storage box 11. An elastic movable rod 13 extending into the installation sleeve 12 is fixedly connected to the bottom of the push plate 15. A return spring 14 is fixedly connected between the elastic movable rod 13 and the installation sleeve 12.

[0039] There are two storage boxes 11, which are symmetrically distributed on the left and right sides of the workbench 1. The storage box 11 is a hollow, open cuboid. By setting up two storage boxes 11, the effect of feeding and unloading materials can be achieved at the same time.

[0040] It should be noted that each storage box 11 has two mounting sleeves 12 inside, which can improve the stability of the push plate 15. The elastic movable rod 13 is slidably connected to the mounting sleeve 12. By setting the return spring 14 and the elastic movable rod 13, when the staff puts the washing machine parts into the storage box 11, it will squeeze the push plate 15, which will cause the return spring 14 to be compressed. When the washing machine parts are taken out one by one, the return spring 14 can rebound due to the decrease in weight, which will drive the washing machine parts to move upward, making it easier to take out the washing machine parts.

[0041] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, a hydraulic cylinder 16 extending to the bottom of the support frame 2 is fixedly installed on the top. A lifting plate 17 is fixedly connected to the output end of the hydraulic cylinder 16. An upper mold 18 is fixedly connected to the side of the lifting plate 17 near the workbench 1. A lower mold 19 that is compatible with the upper mold 18 is fixedly installed on the upper surface of the workbench 1.

[0042] Among them, the pneumatic suction cup 10 is located on the horizontal center line of the lower mold 19, and the upper mold 18 is located directly above the lower mold 19. The lower mold 19 and the upper mold 18 are respectively fixed to the worktable 1 and the lifting plate 17 by bolts, which makes it convenient for the staff to disassemble and assemble the lower mold 19 and the upper mold 18 and to replace different molds.

[0043] It should be noted that by setting the hydraulic cylinder 16 to drive the upper mold 18 to move downward, and by setting the lower mold 19, it is convenient to stamp the washing machine parts. Since the pneumatic suction cup 10 is located at the center of the lower mold 19, it is convenient to remove the washing machine parts from the lower mold 19.

[0044] Please see Figure 5 and Figure 6In this embodiment, a positioning guide rod 20 that passes through the lifting plate 17 is fixedly connected to the bottom of the support frame 2. A pressing block 21 is fixedly connected to one end of the positioning guide rod 20 near the lower mold 19. A support spring 22 is fixedly connected between the pressing block 21 and the lifting plate 17.

[0045] The positioning guide rod 20 is connected to the lifting plate 17 by a sliding connection, and the support spring 22 is sleeved on the outside of the positioning guide rod 20.

[0046] It should be noted that there are two clamping blocks 21 and two positioning guide rods 20. The two clamping blocks 21 are symmetrically distributed on the left and right sides of the upper mold 18. The hydraulic cylinder 16 drives the lifting plate 17 to move downward. At this time, the lifting plate 17 also drives the clamping blocks 21 to move downward, so that the clamping blocks 21 can contact the washing machine parts first, thereby achieving the effect of clamping and positioning the washing machine parts.

[0047] The working principle of the above embodiments is as follows:

[0048] First, the worker places the washing machine parts inside the storage box 11 on the right. Then, the drive motor 4 is started, which drives the transmission gear 5 to rotate. The transmission gear 5 drives the mounting plate 7 to move to the left. Then, the electric push rod 9 is started, which drives the pneumatic suction cup 10 to contact the washing machine parts. After the pneumatic suction cup 10 picks up the washing machine parts, the drive motor 4 drives the mounting plate 7 to move to the right again, and then places the washing machine parts on the lower mold 19. Then, the hydraulic cylinder 16 is started, which drives the upper mold 18 to move downward, and at the same time, the washing machine parts are stamped. After the stamping is completed, the drive motor 4 drives the pneumatic suction cup 10 on the right to move and place the stamped washing machine parts into the storage box 11 on the right. This process can be repeated.
