[0040] refer to Figures 1-9This embodiment provides a CZMU steel shearing device. This device is used for forming, punching, and shearing CZMU steel strips (8) after forming. After forming, the device is responsible for cutting the formed CZMU steel into desired lengths. The shearing device includes a shearing window, a set of six cutting blades positioned within the window, and a mold limiter assembly. It can shear a variety of profiles with high efficiency and precision.

[0041] Specifically, the shear window is provided with a first window 3 and a second window 4. The second window 4 is connected to the first window 3 and is provided on one side of the first window 3. The second window 4 is located below the first window 3. The model limiting group is provided with a first limiting plate 1 and a second limiting plate 2. The first limiting plate 1 and the second limiting plate 2 are relatively arranged on both sides of the first window 3, and the lower end of the first limiting plate 1 extends into the second window 4.

[0042] The first limiting plate 1 is provided with a first mold hole 11 and a second mold hole 12 on the upper and lower sides, and the second limiting plate 2 is provided with a third mold hole 21. The first mold hole 11 and the third mold hole 21 are both placed in the first window 3, and the second mold hole 12 is placed in the second window 4. A limit block 5 is detachably provided at the lower edge of the first window 3.

[0043] The first model hole 11 and the third model hole 21 are paired to form a C-shaped model hole, such as Figure 5 The second model hole 12 is paired with the third model hole 21 to form a Z-shaped model hole, such as Figure 2 The first model hole 11, the third model hole 21 and the limit block 5 cooperate to form an M-shaped model hole, such as Figure 7 The specific structure of the adapted steel strip 8 after forming is as follows Figure 9 .

[0044] The second model hole 12 and the third model hole 21 are both provided with a second folding hole 22 and a third folding hole 23, and the folding angle of the second folding hole 22 is greater than the folding angle of the third folding hole 23. The first model hole 11 is provided with a first folding hole 13 corresponding to the third folding hole 23. Figure 9 To accommodate the hemming or angled hemming of the C-shaped steel 101 or Z-shaped steel 102, the first hemming hole 13 and the third hemming hole 23 are configured as horizontal holes, while the second hemming hole 22 is configured as an angled hole. When shearing the C-shaped steel 101 or Z-shaped steel 102, the first hemming hole 13, the second hemming hole 22, and the third hemming hole 23 can be appropriately matched based on the hemming shape.

[0045] like Figure 5 、 7The C-shaped steel 101 or the M-shaped steel 103 has an inward-folding structure, so the first model hole 11 and the third model hole 21 are also provided with a fourth folding hole 14. The fourth folding hole 14 on the first limiting plate 1 and the second limiting plate 2 can be connected to the first folding hole 13 and the third folding hole 23.

[0046] At the same time, in order to adapt to the different size specifications of the C-shaped steel 101, the Z-shaped steel 102, and the M-shaped steel 103 during shearing, the first limiting plate 1 and the second limiting plate 2 are configured to be movable within the first window 3 and the second window 4.

[0047] Specifically, a first slide rail 31 and a second slide rail 32 are vertically arranged on both sides of the first window 3, the first limiting plate 1 and the second limiting plate 2 are slidably placed on the first slide rail 31 and the second slide rail 32, and a third slide rail is horizontally arranged above the first window 3, and the first slide rail 31 is slidably connected to the third slide rail.

[0048] Correspondingly, the first limit plate 1 and the second limit plate 2 are connected with a first cylinder 33 and a second cylinder 34, and the third slide rail is driven by a third cylinder 35. The first cylinder 33 is a lifting cylinder, used to drive the first limit block 5 to move up and down along the first slide rail 31. The second cylinder 34 is a lifting cylinder, and the third cylinder 35 is a telescopic cylinder. The second cylinder 34 is used to drive the second limit block 5 to move up and down along the second slide rail 32, and the third cylinder 35 is used to drive the second slide rail 32 to move left and right along the third slide rail, thereby realizing the left and right movement of the second limit block 5. Figure 2 、 3 As shown, when shearing large or small Z-shaped steel 102, the up and down movement of the first limit block 5 can be coordinated with the up, down, left and right movement of the second limit block 5 to adjust the Z-shaped model hole to a size suitable for shearing large or small Z-shaped steel 102.

[0049] In this shearing equipment, the shearing of M-shaped steel 103 is involved. In the assembly of the M-shaped model hole, a detachable limiting hole is used for setting. The detachable setting can be removed when the M-shaped model hole is not in use, thereby not affecting the shearing of C-shaped steel 101 and Z-shaped steel 102.

[0050] like Figure 6-7 The detachable arrangement is as follows: a plug-in slot is provided at the bottom edge of the first window 3, and a plug-in hole is provided below the stopper 5; the plug-in hole is plugged into the plug-in slot. The plug-in hole and the plug-in slot are screwed together, and a through slot 36 is provided below the first window 3 for accommodating the screw installation operation. When the stopper 5 is no longer needed, it can be removed by releasing the screw lock.

[0051] In order to eliminate stress during shearing of C-shaped steel 101, Z-shaped steel 102, and M-shaped steel 103 and prevent accidents of curling and warping of steel strip 8, the cutter 6 group includes two cutters 6 and a lifting cylinder 7 for driving the cutters 6 to rise and fall. The driving end of the lifting cylinder 7 is provided with a mounting frame 71. The cutter 6 can be detachably mounted on the mounting frame 71. The mounting part of the cutter 6 is locked to the mounting frame 71 by screws, and the screw connection is convenient for removal and replacement.

[0052] In order to allow the cutter 6 to cut in, a cutting groove is provided at the lower edge of the first window 3 and the second window 4. The lower blade side of the cutter 6 is set as a triangular lower blade side, which is used for shearing. For shearing C-shaped steel 101, Z-shaped steel 102, and M-shaped steel 103, the first cutter 61 is provided with a first triangular cutting edge 63, as shown in FIG. Figure 4 The second cutting knife 62 is provided with a first triangular cutting edge 63 and a second triangular cutting edge 64, and the cutting end of the second triangular cutting edge 64 is higher than the cutting end of the first triangular cutting edge 63, as shown in FIG. Figure 8 .

[0053] Since there are two grooves on both sides of the M-shaped steel 103, in order to prevent the stress of the groove on one side from being too small after the cutter 6 is cut, resulting in curling and warping, a second triangular cutting edge 64 is set higher than the first triangular cutting edge 63. After the first triangular cutting edge 63 cuts into the M-shaped steel 103 for a distance, the second triangular cutting edge 64 shears the groove on one side to balance the shear stress on both sides. The groove on the other side is sheared by the first triangular cutting edge 63. The specific shearing position is as follows: Figure 8 .

[0054] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
