[0042] The lower die 2 detachable installation is on the workbench of oil press, the top of the lower die 2 is "V"-shaped recess 21 for placing angle steel 5 and shape is adapted to pressing head 11, which can conveniently place angle steel 5.The side of the "V"-shaped recess 21 is provided with gap 22 for embedding opening wedge pad 3.When the inclined pressure of the opening wedge pad 3 of the upper die 1 acts on angle steel 5, it will make angle steel 5 expand angle to the gap 22 of the lower die 2.The lower die 2 also includes bottom plate 23, and the bottom plate 23 is connected with "V"-shaped recess 21 through a plurality of lower vertical plates 24.

[0043] In order to make opening wedge pad 3 follow the upper die 1 and press down to the gap 22 of the lower die 2, the opening wedge pad 3 is arranged in the middle of the side surface of the pressing head 11, and the gap 22 is arranged in the middle of the side of the "V"-shaped recess 21.

[0044] In order to facilitate the replacement of corresponding type of opening wedge pad 3, the long vertical surface 32 of the opening wedge pad 3 is provided with clamping block 34 for clamping on the side surface of the pressing head 11, and the pressing head 11 is provided with clamping interface 12 for clamping block 34 clamping at the corresponding position of the opening wedge pad 3. Specifically, referring toFigure 15 The clamping block 34 is an inverted trapezoid, and the clamping port 12 is an inverted trapezoidal notch. The inner side of the clamping port 12 is provided with a baffle 13 for limiting the clamping block 34. When the clamping block 34 of the open-angle wedge pad 3 is clamped in the clamping port 12, the inverted trapezoidal clamping port 12 can clamp the clamping block 34, thereby preventing the open-angle wedge pad 3 from falling. When the angle steel needs to be expanded to other angles, the open-angle wedge pad 3 corresponding to the angle can be replaced. This design can be adapted to angle steels of various lengths and sizes, and has a wide range of applications.

[0045] In order to prevent the open-angle wedge pad 3 from being forced to move upward during pressing, the upper die 1 is detachably provided with a wedge pad clamping die 4 above one side of the open-angle wedge pad 3 to prevent the open-angle wedge pad 3 from moving. The wedge pad clamping die 4 includes a connecting plate 41 and triangular limit pieces 42 provided at both ends of the bottom of the connecting plate 41, and an inner side surface of the triangular limit piece 42 is in contact with the short vertical surface 33 of the open-angle wedge pad 3.

[0047] Working principle: According to the size of the angle that the angle steel 5 needs to be expanded, the open-angle wedge pad 3 with a suitable angle is selected and installed on the upper die 1. During installation, the clamping block 34 of the open-angle wedge pad 3 is inserted into the clamping port 12 of the pressing head 11. Then the wedge pad clamping die 4 is installed on the upper die 1 to clamp the open-angle wedge pad 3.
