There are 2 pressing plates 16, and the two pressing plates 16 are centrosymmetric with each other with respect to the stamping block 7. Above the base 5, a stamping die 17 is inserted and installed. At the rear side of the base 5, a driving motor 20 is provided. The output end of the driving motor 20 is fixedly connected with a bidirectional lead screw 21. On the bidirectional lead screw 21, a first sliding sleeve 22 is provided. On the right side of the bidirectional lead screw 21, a guide rod 23 is provided. On the guide rod 23, a second sliding sleeve 24 is provided. Above the first sliding sleeve 22 and the second sliding sleeve 24, a connecting plate 25 is installed. On the side wall of the connecting plate 25, a limiting block 26 is fixedly installed. At the contact position between the stamping die 17 and the limiting block 26, a limiting groove 27 is opened.

[0030] At the top of the stamping block 7, a slider 8 is fixedly installed. At the contact position between the support plate 4 and the slider 8, a chute 9 is opened. The slider 8 and the chute 9 are in sliding connection. There are 2 sliders 8 and chutes 9. On the left and right sides of the stamping block 7, mounting plates 10 are provided and fixedly installed at the bottom of the support plate 4. At the bottom of the mounting plate 10, a shaft seat 11 is fixedly installed. On the shaft seat 11, an adjusting plate 12 is hinged. The adjusting plate 12 is penetrated and connected with a fixing bolt 13 and extends to the stamping block 7. At the contact position between the stamping block 7 and the fixing bolt 13, a threaded hole 14 is opened. The fixing bolt 13 and the threaded hole 14 are in threaded connection. The external thread of the fixing bolt 13 is in conformity with the internal thread of the threaded hole 14.

[0031] The design of the slider 8 and the chute 9 is to ensure that the stamping block 7 can move stably and vertically on the support plate 4, providing stable guidance, ensuring the accuracy of the stamping block 7 during movement, and at the same time facilitating the sliding disassembly and assembly of the stamping block 7 and the support plate 4. Moreover, the fixing bolt 13 passes through the adjusting plate 12 and is in threaded connection with the threaded hole 14 on the stamping block 7 to fix the installation position of the stamping block 7, avoiding production accidents caused by loosening or movement.

[0032] A stamping die 17 is arranged directly below the stamping block 7. The stamping block 7 matches the groove of the stamping die 17. On the left and right sides of the bottom of the stamping die 17, inserting blocks 18 are fixedly installed. Slots 19 are provided at the contact positions between the inserting blocks 18 and the base 5. The inserting blocks 18 match the slots 19. The bidirectional lead screw 21 is in threaded connection with the first sliding sleeve 22. There are 2 first sliding sleeves 22. The two first sliding sleeves 22 penetrate through the base 5 and extend to the top. The first sliding sleeves 22 are in sliding connection with the base 5. The guide rod 23 is in sliding connection with the second sliding sleeve 24. There are 2 second sliding sleeves 24. The two second sliding sleeves 24 penetrate through the base 5 and extend to the top. The second sliding sleeves 24 are in sliding connection with the base 5. The limiting blocks 26 are snap-fitted with the limiting grooves 27. There are 4 limiting blocks 26 and 4 limiting grooves 27. The four limiting blocks 26 match the four limiting grooves 27.

[0033] The setting that the stamping block 7 matches the groove of the stamping die 17 is the key to ensuring the accuracy and efficiency of the stamping process. Driven by the hydraulic mechanism 3, the stamping block 7 can accurately align with the groove of the stamping die 17 to stamp the material into shape. And the matching design of the inserting blocks 18 and the slots 19 is to ensure that the stamping die 17 can be stably installed on the base 5. This design enables the stamping die 17 to be conveniently installed and disassembled, facilitating the replacement of different dies to meet different production requirements. Moreover, the threaded connection between the bidirectional lead screw 21 and the first sliding sleeve 22 allows the first sliding sleeve 22 to be driven to slide on the base 5 by rotating the bidirectional lead screw 21, thereby adjusting the position of the limiting block 26. The sliding connection between the guide rod 23 and the second sliding sleeve 24 provides additional stability and guidance for the movement of the stamping die 17. It ensures that under the drive of the bidirectional lead screw 21, the limiting block 26 can move smoothly along the predetermined path. At the same time, the snap-fitting installation of the limiting blocks 26 and the limiting grooves 27 is used to ensure the accurate positioning of the stamping die 17 at the installation position on the base 5. It limits the movement range of the die and ensures the stability of the installation position of the stamping die 17.

[0034] The working principle of the present utility model:

[0035] Refer to the attached instruction manual Figures 1-8, when using the present utility model, first, according to production requirements, the slider 8 at the top of the stamping block 7 is slidably installed in the chute 9 at the bottom of the support plate 4, and the adjusting plate 12 is rotated towards the position of the stamping block 7, so that the fixing bolt 13 is exactly aligned with the screw hole 14 of the stamping block 7. The installation position of the stamping block 7 is fixed by the threaded connection between the fixing bolt 13 and the screw hole 14. Then, the stamping die 17 is inserted and installed on the slot 19 of the base 5 through the insertion block 18, and the driving motor 20 is started to drive the bidirectional lead screw 21 to rotate, driving the first sliding sleeve 22 and the second sliding sleeve 24 to slide on the base 5, thereby adjusting the position of the limiting block 26, so that the four limiting blocks 26 approach the stamping die 17 simultaneously, and then the four limiting blocks 26 are engaged and installed with the limiting groove 27, so as to ensure accurate limiting and fixing of the installation position of the stamping die 17. When the stamping block 7 and the stamping die 17 are installed and fixed, the raw material can be placed on the stamping die 17. Subsequently, the hydraulic mechanism 3 is started to drive the support plate 4 to slide on the column 6, and then drive the stamping block 7 to move downward. The telescopic rods 15 and the pressing plates 16 on both sides of the stamping block 7 can press and position the raw material to be stamped during the stamping process, so as to stamp and form the material placed on the stamping die 17. After stamping, the hydraulic mechanism 3 drives the support plate 4 to rise, and the stamping block 7 rises accordingly, completing one stamping operation. When different stamping blocks 7 and stamping dies 17 are to be replaced according to production requirements, the stamping block 7 and the stamping die 17 can be disassembled, and the new stamping block 7 and stamping die 17 can be installed and fixed. Subsequently, the processing work of the stainless steel baking tray can be carried out next.
