Description

Technical Field

[0001] This utility model relates to the field of stamping processing technology for back panels of home appliances, and more specifically, to a steel plate stamping equipment for processing back panels of home appliances. Background Technology

[0002] Appliance back panels are protective panels on the back of home appliances such as refrigerators and washing machines. They serve to protect internal components, support the structure, and assist in heat dissipation.

[0003] The steel plate stamping equipment used for processing home appliance back panels is a machine specifically designed to process steel plates into the shape of home appliance back panels. It uses molds and strong pressure to cause plastic deformation of the steel plate, thereby stamping out the back panel shape that meets the design requirements. This equipment usually includes a press, stamping molds, feeding devices, etc., and can complete the stamping process of steel plates efficiently and accurately, ensuring the quality and production efficiency of home appliance back panels.

[0004] However, existing steel plate stamping equipment for home appliance back panel processing mostly places the workpiece in the lower mold, and then starts the hydraulic system to drive the upper mold to press down, thereby stamping the home appliance back panel workpiece. However, in actual use, existing steel plate stamping equipment often needs to stamp back panels of various sizes and shapes, but existing molds are mostly installed by bolt fixing. This fixing method has many drawbacks. When it is necessary to change molds of different specifications, the staff must spend a lot of time disassembling and installing bolts. First of all, there are usually many bolts, and the process of disassembling and installing them one by one is very cumbersome. This series of operations makes it extremely inconvenient for the staff when it is necessary to change molds, which greatly affects the work efficiency of the staff.

[0005] Moreover, existing stamping equipment often causes damage to the mold itself due to frequent and high-intensity stamping actions. Due to the huge impact force during the stamping process, key parts of the mold, such as the cutting edge and forming surface, are prone to wear and deformation. Long-term stamping operations will cause these damages to accumulate continuously, resulting in a decrease in the precision of the mold, which in turn affects the quality of the stamped appliance back panel.

[0006] In view of this, we propose a steel plate stamping equipment for processing the back panel of home appliances. Utility Model Content

[0007] Technical problems to be solved

[0008] The purpose of this utility model is to provide a steel plate stamping equipment for processing the back panel of home appliances, so as to solve the problems mentioned in the background art.

[0009] Technical solution

[0010] A steel plate stamping device for processing home appliance back panels includes a fixed base with supporting feet at the bottom. A lead screw motor is mounted on the side wall of the fixed base, and the output end of the lead screw motor extends into the fixed base and is connected to a lead screw. Multiple moving components are sleeved on the outer circumference of the lead screw, including a moving table. A fixed frame is also fixedly connected to the outer wall of the fixed base. A hydraulic cylinder is mounted on the top of the fixed frame, and a controller is mounted on the front outer wall of the fixed frame. A descending frame is connected to the output end of the hydraulic cylinder, and a locking plate is slidably engaged inside the descending frame. An upper mold is mounted at the bottom of the locking plate.

[0011] Preferably, the outer wall of the movable platform is rotatably connected to a rotating threaded rod, and a movable frame is sleeved on the outer circumference of a plurality of rotating threaded rods.

[0012] Preferably, a second rubber pad is provided on the top of the movable frame, and a rotating rod is also rotatably connected to the top of the movable frame.

[0013] Preferably, the rotating rod has a cavity inside, a return spring is provided at the bottom of the cavity, a connecting ring is connected to the end of the return spring, a limit plug is fixedly connected to the inner wall of the connecting ring, and a rubber pad is also provided at the top of the rotating rod.

[0014] Preferably, the inner wall of the moving platform is also slidably engaged with a lower mold, and the top of the lower mold is provided with a limiting hole that matches the limiting rod.

[0015] Preferably, the outer wall of the lowering frame is rotatably connected to a rotation limit rod, the outer wall of the rotation limit rod is threaded with a fixing bolt, and the side wall of the upper mold is provided with a second limiting hole that matches the fixing bolt. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are as follows: During use, the workpiece to be stamped can be placed inside the lower mold. Then, the starting of the lead screw motor drives the moving table to the bottom of the upper mold. Next, the hydraulic cylinder is activated to lower the upper mold and stamp the workpiece. After stamping, the lead screw motor is activated to reset the moving table, while another moving table can move another workpiece to the bottom of the upper mold. This stamping cycle continues. When the lower mold needs to be replaced, multiple limit rods can be pulled to move them away from the limit hole. Then, multiple rotating threaded rods are rotated to move the moving frame backward, away from the top of the lower mold, allowing it to be removed for replacement. When replacing the upper mold, simply loosen the fixing bolts and rotate the limit rod upward to remove it. The multi-station design speeds up the replacement of the lower mold, reducing downtime and minimizing the impact on stamping efficiency. Furthermore, cleaning and maintenance of the lower mold are more convenient, reducing the inconvenience of requiring downtime for maintenance.

[0017] In addition, a second rubber pad is installed on the top of the movable frame used for limiting the lower die, and a first rubber pad is also equipped on the top of the rotating rod. During long-term continuous operation and frequent high-intensity stamping processes, the second and first rubber pads can play a buffering role. When each stamping action occurs, a huge impact force is generated between the upper and lower dies. The second and first rubber pads, with their good elastic deformation capacity and damping characteristics, effectively absorb and disperse this impact force, significantly reducing the instantaneous impact force when the upper and lower dies come into direct contact. This minimizes wear, deformation and other forms of damage to the die surface caused by frequent stamping, thereby extending the service life of the die. Attached Figure Description

[0028] This allows for better and more continuous stamping of the back panel, and reduces the impact on the continuous processing of the stamping equipment when the lower die is being maintained and cleaned.

[0029] A fixed frame 300 is also fixedly connected to the outer wall of the fixed base 100. A hydraulic cylinder 310 is provided on the top of the fixed frame 300. A controller 320 is provided on the front outer wall of the fixed frame 300. A descending frame 330 is connected to the output end of the hydraulic cylinder 310. A locking plate 333 is slidably engaged inside the descending frame 330. An upper mold 334 is provided at the bottom of the locking plate 333.

[0030] Specifically, the outer wall of the movable table 200 is rotatably connected to a rotating threaded rod 210, and a movable frame 220 is sleeved on the outer circumference of multiple rotating threaded rods 210, so as to facilitate the use of the movable frame 220 to limit the top of the lower mold 250.

[0031] Furthermore, a rubber pad 240 is provided on the top of the movable frame 220, and a rotating rod 230 is rotatably connected to the top of the movable frame 220, so that the lower mold 250 can be limited by using multiple rotating rods 230.

[0032] Furthermore, the rotating rod 230 has a cavity 232 inside, a return spring 233 is provided at the bottom of the cavity 232, a connecting ring 234 is connected to the end of the return spring 233, a limit plug 235 is fixedly connected to the inner wall of the connecting ring 234, and a rubber pad 231 is also provided at the top of the rotating rod 230.

[0033] Furthermore, the inner wall of the moving platform 200 is also slidably connected to the lower mold 250, and the top of the lower mold 250 is provided with a limiting hole 251 that matches the limiting rod 235.

[0034] It is worth noting that the outer wall of the descending frame 330 is rotatably connected to a rotation limit rod 331, and the outer wall of the rotation limit rod 331 is threaded with a fixing bolt 332. The side wall of the upper mold 334 is provided with a limit hole 335 that matches the fixing bolt 332, so as to facilitate the limit and fixation of the upper mold 334.

[0035] In some embodiments, the device can be powered by an external conventional power source.

[0036] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0037] Working principle: During use, the workpiece to be stamped can be placed inside the lower mold 250. Then, the starting of the lead screw motor 120 drives the moving table 200 to move to the bottom of the upper mold 334. After that, the hydraulic cylinder 310 is activated to drive the upper mold 334 to descend and stamp the workpiece. After stamping is completed, the lead screw motor 120 is activated to drive the moving table 200 to reset, and another moving table 200 can drive another workpiece to be stamped to the bottom of the upper mold 334. This stamping cycle is repeated. When it is necessary to replace the lower mold, multiple limit rods 235 can be pulled first to move the limit rods 235 away from the limit hole 251. Then, multiple rotating threaded rods 210 are rotated to drive the moving frame 220 to move backward away from the top of the lower mold 250. At this time, the lower mold 250 can be pulled out. When replacing the upper mold 334, simply loosen the fixing bolt 332 and then rotate the rotating limit rod 331 upwards. At this point, the upper mold 334 can be pulled out for replacement. Its multi-station design can better speed up the replacement efficiency of the lower mold, reduce the impact of long-term downtime on the stamping processing efficiency when replacing molds, and also make the cleaning and maintenance of the lower mold more convenient, reducing the trouble caused by the need for personnel to stop the machine to perform maintenance on the lower mold. In addition, a second rubber pad 240 is set on the top of the moving frame 220 used to limit the lower mold 250, and a first rubber pad 231 is also equipped on the top of the rotating rod 230. During the long-term continuous operation of the equipment and the frequent high-intensity stamping processing, the second rubber pad 240 and the first rubber pad 231 can play a buffering role. Each time a stamping action occurs, a huge impact force is generated between the upper die 334 and the lower die 250. Rubber pads 2 and 1, with their good elastic deformation ability and damping characteristics, effectively absorb and disperse this impact force, significantly reducing the instantaneous impact force when the upper die 334 and the lower die 250 are in direct contact. This minimizes the wear, deformation and other forms of damage to the die surface caused by frequent stamping, thereby extending the service life of the die.
