Description

Segmental Shearing Machine with Upper Knife

technical field

The utility model relates to a shearing machine used for cutting the sheet material after longitudinal shearing and slitting of a metal coil, and belongs to the technical field of the shearing machine.

Background technique

The uncoiling and leveling production line is used for a series of processing operations such as uncoiling, leveling and shearing of metal sheets, mainly including leveling machines, slitting machines and shearing machines. The uncoiled and leveled sheet is longitudinally cut into narrow strips of required width by slitting machine, and then cut into flat sheets of required length by shearing machine.

The shearing machine usually completes the cutting of the sheet by a moving upper blade and a fixed lower blade. The upper blade exerts a shearing force on the metal sheet, and the upper blade is generally inclined.

The upper blade of the existing plate shearing machine moves as a whole under the drive of the driving mechanism, and the whole body falls and cuts, which makes a plate shearing machine only cut a kind of length of sheet material, and the length of each cutting is the same. This method is suitable for mass production, and the cutting efficiency is high. But when needing to cut another kind of length sheet material, just need to resize, can not obtain the sheet material of multiple lengths at the same time.

detailed description

As shown in Fig. 1 and Fig. 2, the upper knife section type shearing machine of the present utility model comprises a main frame, and the main frame is connected by a left wallboard 6, a right wallboard 11, a lower connecting plate 2 and an upper connecting plate 8. In this way, the lower connecting plate 2 and the upper connecting plate 8 are respectively connected to the lower and upper parts of the left wall panel 6 and the right wall panel 11. The lower connecting plate 2 is provided with a support roller table 14 and a lower knife seat 17 at the front and rear respectively, and the lower knife seat 17 is connected with a lower blade 19, see FIG. 2 . A left guide block 3 and a right guide block 12 are respectively provided on the inner side of the top of the left wall panel 6 and the right wall panel 11 , and an upper knife seat 16 is arranged between the left guide block 3 and the right guide block 12 . At least two upper knife units are arranged on the upper knife seat 16 .

In this embodiment, two upper knife units are set. The main upper knife unit is directly arranged on the upper knife seat 16, see Fig. 1 and Fig. 2, including the main pressing seat 13, the pressing spring 18, the main shearing hydraulic cylinder 9 and the main upper knife sub-seat 10, the main upper knife sub-seat 10, the main upper knife sub-seat The seat 10 is directly connected to the upper knife seat 16, and a compression spring 18 is arranged between the main upper knife sub-seat 10 and the upper knife seat 16.
