Description

Technical Field

[0001] This utility model relates to the field of refrigerator center beam processing technology, specifically an automated stamping device for refrigerator center beams. Background Technology

[0002] The refrigerator center beam is a structural component in a refrigerator used to connect two inner liner compartments or cabinet liners. It is usually located in the middle of the refrigerator and primarily serves to connect and support the inner liner compartments of different chambers (such as the freezer and refrigerator compartments), making the refrigerator structure more stable. It also helps maintain the refrigerator's internal airtightness and reduces cold air loss. Common refrigerator center beams include a plastic beam body and a metal support component. The plastic beam body is generally H-shaped, with upper and lower positioning grooves for positioning the two inner liner compartments respectively. The metal support component is fixed to the plastic beam body and has a supporting wall protruding into the positioning grooves to abut against and position the inner liner compartments. This reduces the thermal conductivity, preventing condensation and frost, while also ensuring the strength of the center beam.

[0003] The refrigerator center beam needs to be stamped during the manufacturing process. To address this, we propose an automated stamping device for the refrigerator center beam. Utility Model Content

The conveyor belt passes through the stamping table, and multiple sets of mold seats are installed on the upper surface of the conveyor belt. A lower mold is fixedly installed in the upper center of the mold seat, and limit sleeves are provided at the four corners of the bottom of the mold seat. A lifting platform is provided in the inner center of the stamping table, and an upper stamping mold is provided on the top of the stamping table. A stamping cylinder is provided on the top of the upper stamping mold. The lifting platform is movably installed in the inner center of the stamping table and is located in the lower center of the conveyor belt. Multiple sets of lifting hydraulic cylinders are provided at the bottom of the lifting platform, and limit posts are provided at the four corners of the upper end of the lifting platform. When the mold seat moves to the upper center of the lifting platform, the limit posts are inserted into the limit sleeves to limit and lock the mold seat.

[0014] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 3As shown, an automated stamping device for the center beam of a refrigerator in this embodiment includes a stamping table 6 and a conveyor belt 1. The conveyor belt 1 passes through the stamping table 6. Multiple sets of mold bases 2 are installed on the upper surface of the conveyor belt 1. A lower mold 3 is fixedly installed in the middle of the upper end of the mold base 2. Limit sleeves 4 are provided at the four corners of the bottom end of the mold base 2. A lifting platform 7 is provided in the middle of the inner side of the stamping table 6. An upper stamping mold 11 is provided on the top of the stamping table 6. A stamping cylinder 12 is provided on the top of the upper stamping mold 11. The lifting platform 7 is movably installed in the middle of the inner side of the stamping table 6. The lifting platform 7 is located in the middle of the bottom end of the conveyor belt 1. Multiple sets of lifting hydraulic cylinders 8 are provided at the bottom of the lifting platform 7. Limit posts 9 are provided at the four corners of the upper end of the lifting platform 7. When the mold base 2 moves to the middle of the upper end of the lifting platform 7, the mold base 2 is locked by inserting the limit posts 9 into the limit sleeves 4.

[0015] During use, the operator needs to place the refrigerator beam to be processed in the lower mold 3, and then transport the lower mold 3 to the position directly below the upper stamping mold 11 by the conveyor belt 1. At this time, the lifting hydraulic cylinder 8 pushes the lifting platform 7 to rise, so that the limit post 9 is inserted into the limit sleeve 4 to achieve positioning and locking of the lower mold 3. Then the stamping cylinder 12 can be started to push the upper stamping mold 11 to descend, thereby realizing the stamping processing of the refrigerator beam.

[0016] A support plate 5 is provided at the bottom center of the mold base 2, and a support seat 10 is provided at the top center of the lifting platform 7. The support seat 10 corresponds to the position of the support plate 5 and is located at the bottom center of the support plate 5. During the stamping process, the support seat 10 needs to be pushed against the bottom of the support plate 5 to enhance the stability of the mold base 2 and avoid the mold base 2 from shaking due to lack of stable support during the stamping process. After the support seat 10 supports the support plate 5, it is locked in place by inserting the limit post 9 into the limit sleeve 4, thereby effectively improving the stability during the stamping process and enabling the upper stamping die 11 and the lower die 3 to close accurately, thereby enhancing the accuracy and stability of the stamping process of the refrigerator beam.

[0017] In some examples, the lifting hydraulic cylinder 8 is fixedly installed in the middle of the inner cavity of the stamping table 6, and the lifting hydraulic cylinder 8 is used to drive the lifting table 7 to perform lifting movements.

[0018] In some examples, a support bracket 14 is installed on the top of the stamping table 6, and the stamping cylinder 12 is fixedly installed in the middle of the upper end of the support bracket 14, which serves to provide stable support.

[0019] In some examples, limit guide rods 13 are provided on both sides of the top of the upper stamping die 11. The limit guide rods 13 are located on both sides of the stamping cylinder 12 and are slidably connected to the top of the stamping table 6. Limit sleeves 15 are provided on both ends of the inner side of the support top frame 14. The limit guide rods 13 are slidably installed in the middle of the inner side of the limit sleeves 15. The limit sleeves 15 limit the lifting and lowering of the limit guide rods 13, thereby improving the stability and accuracy of the stamping cylinder 12 pushing the upper stamping die 11 to move up and down.

[0020] The working principle of this utility model is as follows: During use, the operator needs to stand at the head of the conveyor belt 1 and place the refrigerator beam to be stamped into the lower mold 3. The lower mold 3 is then transported by the conveyor belt 1 to achieve automated feeding. When the lower mold 3 moves to the position directly below the upper stamping mold 11, it stops. At this time, multiple sets of lifting hydraulic cylinders 8 are activated, which pushes the lifting platform 7 upward, thereby inserting the limiting post 9 into the limiting sleeve 4 at the bottom of the mold base 2, thereby locking the mold base 2. As the lifting platform 7 continues to rise, it continues until the support base 10 and the bottom of the support plate 5 are fitted together, thereby achieving stable locking support for the mold base 2. At this time, the upper stamping cylinder 12 will be activated to push the upper stamping die 11 down. Under the limiting guide of the limiting guide rod 13, the upper stamping die 11 can accurately close with the lower die 3, thereby effectively improving the accuracy of stamping the refrigerator beam.

[0021] After the stamping process is completed, the stamping cylinder 12 drives the upper stamping die 11 to rise. At the same time, the lifting hydraulic cylinder 8 drives the lifting platform 7 to descend, releasing the limit lock on the die holder 2. At this time, the conveyor belt 1 continues to start to transport the next die holder 2. In addition, when the conveyor belt 1 rotates to the corner position, the die holder 2 will be in an inverted state, thereby realizing the automatic unloading of the refrigerator beam that has completed the stamping process.

[0022] The setting of the limiting sleeve 4 and the limiting post 9 in this utility model allows for precise positioning of the lower mold 3, which is then stably supported by the support seat 10. This effectively improves the accuracy and stability of the entire stamping mold closing process. Furthermore, in conjunction with the automatic feeding function of the conveyor belt 1, the entire stamping process becomes an automated process, thereby effectively improving processing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
