Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal grooving, in particular to a sheet metal grooving die. Background Art

[0002] A sheet metal grooving die usually includes an upper die mechanism and a lower supporting die mechanism. The upper die mechanism may include a top plate, an upper die support seat, a supporting pad, a fixing plate, a platen pad, an upper platen and a push cylinder, and the lower supporting die mechanism may include a supporting bottom plate, a lower supporting die seat, a supporting die pad and a supporting die, and the die is used to flatten the sheet metal during the grooving and flattening process of the sheet metal.

[0003] After searching, the utility model with the announcement number CN219944255U discloses a sheet metal grooving die. Although the utility model patent solves the problem that the prior art is difficult to adjust the size of the die grooving, and can only press the sheet metal down at a fixed gap, resulting in the device being unable to press the sheet metal down according to the required grooving size and unable to clean the groove body, resulting in the waste chips left after multiple grooving seriously affecting the next grooving, thereby reducing the working efficiency of the device; however

[0004] First, the current utility model patent lacks the function of fixing the sheet metal. When the sheet metal to be punched is long or not flat enough, it is easy to cause the sheet metal to shift during punching, which eventually leads to the deviation of the groove position and error;

[0028] In one embodiment, a second connection groove 17 is provided on one side of the upper mold 3, a tool 18 is connected in the second connection groove 17, a threaded hole 19 is provided in the tool 18 and the upper mold 3, and a bolt 20 is threadedly connected in the threaded hole 19. A connection plate 22 is fixedly connected to the lower surface of the press 1, and a threaded rod 23 is threadedly connected in the connection plate 22. The threaded rod 23 is provided in two groups, and the two groups of threaded rods 23 are located on both sides of the workbench 4.

[0029] In one embodiment, two groups of threaded holes 19 and bolts 20 are provided, and the two groups of threaded holes 19 and bolts 20 are located on both sides of the first electric hydraulic rod 2. The two groups of threaded holes 19 and bolts 20 together fix the tool 18 to the upper mold 3, making the tool 18 more stable, and preventing the tool 18 from deviating during the cutting process of the sheet metal 6, causing cutting errors. The shape of the tool 18 is "L" shaped.

[0030] In one embodiment, two groups of housing 9, connecting block 10 and connecting rod 11 are provided, and the two groups of housing 9, connecting block 10 and connecting rod 11 are located at both ends of support rod 8. The two groups of housing 9, connecting block 10 and connecting rod 11 are driven by the second electric hydraulic rod 7 to press the sheet metal 6 synchronously, so as to ensure the stability of the sheet metal 6 during the groove pressing process and prevent the sheet metal 6 from being offset due to uneven force.

The second electric hydraulic rod 7 is extended to drive the support rod 8 to move toward the sheet metal 6. The movement of the support rod 8 drives the shell 1 9 to move. Since the shell 1 9 is hinged with the connecting block 10 through the connecting rod 1 11, the connecting block 10 moves to the left with the movement of the shell 1 9. Under the cooperation of the connecting rod 2 12 and the shell 2 13, the connecting block 10 swings around the connecting rod 2 12. Since the connecting rod 3 15 is connected to the connecting groove 14, the connecting rod 15 is connected to the connecting groove 14. The movement of rod 2 12 can drive connecting rod 3 15 to move. Since connecting rod 3 15 and sliding rod 16 are fixedly connected, the movement of connecting rod 3 15 drives sliding rod 16 to slide downward. Since fixed block 21 is fixedly connected to sliding rod 16, sliding rod 16 drives fixed block 21 downward, thereby fixing sheet metal 6 to prevent the position of the groove from being offset and causing errors when the sheet metal 6 to be punched is long or not flat enough. Start the first electric hydraulic rod 2, the first electric hydraulic rod 2 extends to drive the upper mold 3 to move downward, and the lower mold 3 is moved downward.

When the sheet metal 6 needs to be cut, the tool 18 is placed in the connecting groove 17 according to the position and shape of the connecting groove 17, and the threaded holes 19 on the upper mold 3 and the tool 18 are aligned. According to the position of the threaded hole 19, the connecting groove 17 and the tool 18 are connected by bolts 20. When the upper mold 3 follows the first electric hydraulic rod 2 to groove the sheet metal 6 downward, the tool 18 follows the upper mold 3 to cut the sheet metal 6 downward, and the groove pressing and cutting processes are completed at the same time. , which improves the efficiency of grooving the sheet metal 6 to a certain extent; when the lower mold 5 needs to be replaced, the staff manually turns the handle 24. Since the threaded rod 23 and the handle 24 are fixedly connected, the rotation of the handle 24 drives the threaded rod 23 to rotate. Since the threaded rod 23 is threadedly connected to the connecting plate 22, and the connecting plate 22 is stationary, the threaded rod 23 moves on the connecting plate 22, and the threaded rod 23 moves away from the workbench 4, thereby releasing the clamping of the workbench 4, making it easy to replace the lower mold 5, and improving the convenience of the device.
