Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for rapid blanking. Background Technology

[0002] Stamping dies are commonly used tooling in stamping processes. They are mainly used to punch holes or grooves of the required shape on sheet metal. Their core structure includes a punch, a die, and a guiding mechanism. The working principle is that the punch is driven downward by the press, causing the sheet metal to undergo plastic deformation or separation in the gap between the punch and the die, thereby forming the target hole shape.

[0003] Some rectangular workpieces are formed by stamping steel strips, and the workpieces also have stamped grooves inside. During the processing of these steel strips, they are manually placed on the stamping die for stamping. After stamping, the scrap material falls from the blanking hole of the die, but the workpiece, although pressed out, is still inside the long steel strip. It is necessary to manually lift the steel strip and flip it outward so that the workpiece falls off the steel strip. This blanking method is very time-consuming. The steel strips are relatively heavy (e.g., a steel strip with a thickness of 3mm and a length of 1m is about 23.5kg). Frequent lifting and flipping can easily cause back and shoulder strain for workers. Long-term operation may cause occupational health problems. In order to solve the above problems, we have proposed this stamping die for rapid blanking. Utility Model Content

[0022] like Figure 1-4 As shown, a stamping die for rapid material discharge includes a base 1, a lower die 3 and an upper die 6. The lower end of the base 1 is provided with a material discharge groove, which is shown in the figure. Its size is larger than the inner ring groove in the forming groove 2. The upper end of the lower die 3 is provided with a forming groove 2. A protective frame 19 is fixedly connected to the lower end of the lower die 3. The protective frame 19 can prevent waste material from falling into the base 1.

[0023] The lower mold 3 is provided with a drive mechanism for moving the waste material. The drive mechanism includes two connecting plates 20 at the lower end of the lower mold 3. A hydraulic cylinder 9 is fixedly connected to the upper end of the connecting plate 20. The output end of the hydraulic cylinder 9 is provided with an ejector pin 7. The side wall of the lower mold 3 is provided with a mounting frame 11. The side wall of the mounting frame 11 is provided with a motor 13. The output shaft of the motor 13 is fixedly connected with a reciprocating screw 12. The reciprocating screw 12 is threadedly connected to a moving frame 14. The moving frame 14 is provided on the reciprocating screw 12. The inner wall of the moving frame 14 is provided with a push plate 16. Two mounting plates 4 are provided on both side walls of the lower mold 3. A limit plate 5 is provided inside the mounting plate 4.

[0024] The mounting plate 4 is provided with an adjustment mechanism for adjusting the height of the limiting plate 5. The adjustment mechanism includes a first screw 15 that passes through the upper end of the mounting plate 4. The lower end of the first screw 15 is rotatably connected to the upper end of the limiting plate 5. A first handwheel is fixedly connected to the side wall of the first screw 15.

[0025] In this utility model, a second screw 18 is provided through the upper end of the movable frame 14. The second screw 18 is rotatably connected to the push plate 16. A second handwheel is fixedly connected to the side wall of the second screw 18. The push plate 16 is slidably connected to the movable frame 14, so that the height of the push plate 16 is adjustable, which makes it convenient for the equipment to push out workpieces of different thicknesses, thereby expanding the applicability of the device.

[0026] In this utility model, the lower end of the limiting plate 5 is provided with multiple balls 17, which are equally spaced, so that the sliding contact between the limiting plate 5 and the steel strip becomes rolling, making the movement of the steel strip smoother.

[0027] In this utility model, a first connecting block 8 is fixedly connected to the side wall of the mounting plate 4, and a first bolt is provided on the side wall of the first connecting block 8, so that the mounting plate 4 can be detached and assembled with the base 1, which facilitates the transportation of the equipment after it leaves the factory.

[0030] It should be noted that this utility model is a stamping die for rapid blanking. As shown in the figure, the user inserts the steel strip into the two mounting plates 4 from right to left and moves them into the lower die 3. When the upper die 6 presses down to stamp, the rectangular workpiece is pressed into the forming groove 2, and the waste material in the rectangular workpiece falls from the blanking groove. After the upper die 6 is reset, the two first hydraulic cylinders 9 are started. The output end of the first hydraulic cylinder 9 drives the ejector pin 7 to move up and down, pushing the workpiece out of the steel strip. Then the motor 13 is started, and the output shaft of the motor 13 drives the reciprocating screw 12 to rotate. The moving frame 14 drives the push plate 16 to move towards the workpiece and push the workpiece out of the die. After the moving frame 14 is reset, the operator continues to push the steel strip into the die.
