DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an embodiment of a multi-directional stamping die adapted to a local straight edge structure.

[0024] A multi-directional stamping forming die adapted for a local straight edge structure comprises a first support platform 1 and a second support platform 2, a lower die 3 and an upper die 4 are respectively mounted on the first support platform 1 and the second support platform 2, a plurality of fixed blocks 5 are fixedly mounted on the lower die 3, a plurality of hydraulic cylinders 6 are fixedly mounted on the fixed blocks 5, a plurality of stamping blocks 7 connected to the hydraulic cylinders 6 are arranged above the lower die 3, a cooling mechanism 8 is arranged on one side of the first support platform 1, the cooling mechanism 8 comprises two electric guide rails 9 symmetrically mounted on the first support platform 1, a first support frame 10 is mounted between the two electric guide rails 9, a fixed frame 11 is fixedly mounted on the first support frame 10, two second support frames 12 are fixedly mounted on the bottom of the fixed frame 11, and a fan 13 is arranged on the second support frame 12. By setting the cooling mechanism 8, the parts can be cooled quickly. After the parts are stamped and formed by the upper mold 4 and multiple punching blocks 7, the second support platform 2 and the upper mold 4 are separated from the lower mold 3, and the multiple electric guide rails 9 are started at the same time to drive the first support frame 10 to move the two fixed frames 11 to the top of the parts, and then the two fixed frames 11 are started to supply air to cool the parts, so that the temperature of the parts can be quickly reduced to avoid long-term high temperature affecting its quality, and at the same time, it can also prevent the lower mold 3 from being damaged.

[0025] A fixing frame 14 is fixedly installed on the top of the fixing frame 11, and a screw 15 connected by threads is arranged on the fixing frame 14. A support block 16 is movably installed at the bottom of the screw 15. A limit plate 17 is fixedly installed on one end of the support block 16. Rubber pads 18 are fixedly installed on the inner wall of the limit plate 17 and the inner wall of the second support frame 12. A plurality of push rods 19 are symmetrically fixedly installed on the top of the screw 15. Through the arrangement of the fixing frame 14, the screw 15, the support block 16 and the limit plate 17, the screw 15 is rotated to descend on the fixing frame 14 through the threads, and the support block 16 and the limit plate 17 are driven to descend, so that the limit plate 17 presses down the fan 13 to fix it on the second support frame 12, and prevents the fan 13 from shaking greatly during operation, so as to ensure the stability of its installation. Through the arrangement of the rubber pad 18, the vibration of the fan 13 at the operating point can be further reduced. Through the arrangement of the push rod 19, the screw 15 can be easily pushed to rotate.

[0026] Two limit grooves 20 are symmetrically provided on the inner wall of the fixed frame 14, and a limit block 21 connected to the support block 16 is slidably installed on the limit groove 20. A fixed plate 22 is fixedly installed on the output end of the hydraulic cylinder 6, and the fixed plate 22 is fixedly connected to the stamping block 7 by multiple bolts. A groove 23 is provided inside the lower mold 3, and multiple hydraulic rods 24 are fixedly installed inside the groove 23. A top plate 25 connected to the multiple hydraulic rods 24 is provided on the top of the groove 23. By setting the limit groove 20 and the limit block 21, the limit block 21 slides in the limit groove 20 as the support block 16 descends, which can play a role of limiting support for the support block 16, preventing it from rotating with the screw 15, ensuring that the limit plate 17 can smoothly descend to press down the fan 13, and by setting the fixed plate 22, the punching block 7 and one end of the hydraulic cylinder 6 are fixed by the fixed plate 22 and the threaded connection, so that the punching block 7 can be separated from one end of the hydraulic cylinder 6, which is convenient for replacement when the punching block 7 is worn, and by setting the groove 23, the hydraulic rod 24 and the top plate 25, after the parts are stamped, multiple hydraulic rods 24 are started at the same time so that their output ends drive the top plate 25 to rise, so that the top plate 25 can lift the parts from the lower mold 3, so that the staff can remove the parts from the lower mold 3.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a multi-directional stamping forming die adapted to a local straight edge structure provided in this embodiment is as follows:

[0028] Step 1: After placing the part to be punched on the lower die 3, the upper die 4 is lowered to fit with the lower die 3 to punch the part. When the part is partially straightened, the hydraulic cylinder 6 is started so that its output end drives the punching block 7 to move closer to the part, so that the punching block 7 punches the part to complete the local straightening of the part.

[0029] Step 2: After all the parts are stamped and formed, separate the upper mold 4 and the lower mold 3, and start the multiple electric guide rails 9 to drive the first support frame 10 to move the two fixed frames 11 to the top of the parts, and then start the two fixed frames 11 to start supplying air to cool the parts so that the temperature of the parts can drop quickly.

[0030] In summary, in the present embodiment, according to a multi-directional stamping forming die adapted to a local straight-edge structure of the present embodiment, by means of the setting of the fixing frame 14, the screw 15, the support block 16 and the limit plate 17, the screw 15 is rotated to descend on the fixing frame 14 through the thread, and drives the support block 16 and the limit plate 17 to descend, so that the limit plate 17 presses down the fan 13 to fix it on the second support frame 12, and prevents the fan 13 from shaking significantly during operation, so as to ensure the stability of its installation. By means of the setting of the rubber pad 18, the vibration of the fan 13 at the operating time can be further reduced. By means of the setting of the push rod 19, the screw 15 can be easily pushed to rotate. By means of the setting of the limit groove 20 and the limit block 21, the limit block 21 As the support block 16 descends, it slides in the limit groove 20, which can play a role of limiting support for the support block 16, preventing it from rotating with the screw 15, ensuring that the limit plate 17 can smoothly descend to press down the fan 13, and through the setting of the fixed plate 22, the punching block 7 and one end of the hydraulic cylinder 6 are fixed by the fixed plate 22 and the threaded connection, so that the punching block 7 can be separated from one end of the hydraulic cylinder 6, which is convenient for replacement when the punching block 7 is worn. Through the setting of the groove 23, the hydraulic rod 24 and the top plate 25, after the stamping of the parts is completed, multiple hydraulic rods 24 are started at the same time so that their output ends drive the top plate 25 to rise, so that the top plate 25 can lift the parts from the lower mold 3, so that the staff can remove the parts from the lower mold 3.
