the buffer module comprises a buffer module shell, a spring contact plate and a limiting panel, wherein a groove is formed in the middle of the buffer module shell, the spring is arranged in the groove of the buffer module shell, the lower end of the spring is fixed at the bottom of the groove, the spring contact plate is connected with the upper end of the spring, the limiting panel is arranged on the upper portion of the buffer module shell and is positioned right above the spring contact plate, a groove is formed in the limiting panel, and the size of the groove is smaller than that of the spring contact plate;

two sides of the upper convex pressing edge die are provided with upper convex pressing edge die guide columns; the upper convex pressing edge die guide column moves up and down in the lower groove edge die guide groove; spring compression columns are arranged on two sides of the lower end blade surface of the upper convex pressing blade die; the shape and the size of the cross section of the spring compression column are the same as those of the groove in the limiting panel, and the lower end face of the spring compression column penetrates through the groove in the limiting panel and is in contact with the spring contact plate.

Further, the upper edges of the front and rear side walls of the lower groove cutting die are provided with arc-shaped cutting surfaces opposite to the lower end arc-shaped cutting surfaces of the upper convex pressing cutting die.

Furthermore, the shapes of the groove in the middle of the shell of the buffer module, the spring contact plate and the open groove in the limiting panel are circular at one end and rectangular at the other end.

The utility model has the advantages and the beneficial effects that: the utility model relates to a fixed shear blade with lower sword buffer can realize protruding pressure cutting die and push down the buffering of in-process, avoids the cutting surface direct contact low groove cutting die bottom of protruding pressure cutting die to the life of protruding pressure cutting die has been prolonged.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b):

a fixed shear blade with a lower blade buffer device comprises a base 1, a lower groove blade die 2, an upper convex blade die 3, an upper convex blade die guide post 4, a lower groove blade die guide groove 5, a buffer module and a spring compression post 10;

the lower groove cutting die 2 is arranged on the surface of the base 1, and lower groove cutting die guide grooves 5 are formed in two ends of a groove of the lower groove cutting die 2; the two buffer modules are respectively arranged at two ends of the groove, and the rear side of each buffer module is close to the lower groove cutting die guide groove 5; the lower end of the upper convex pressing edge die 3 is provided with a plurality of arc-shaped edge surfaces for cutting the pipe; the arc-shaped blade surface at the lower end of the upper convex pressing blade die 3 is positioned right above the groove of the lower groove blade die 2;

the buffer module comprises a buffer module shell 6, a spring 7, a spring contact plate 8 and a limiting panel 9, wherein a groove is formed in the middle of the buffer module shell 6, the spring 7 is arranged in the groove of the buffer module shell 6, the lower end of the spring 7 is fixed at the bottom of the groove, the upper end of the spring 7 is connected with the spring contact plate 8, the limiting panel 9 is arranged at the upper part of the buffer module shell 6 and is positioned right above the spring contact plate 8, a groove is formed in the limiting panel 9, and the size of the groove is smaller than that of the spring contact plate 8;

two sides of the upper convex pressing edge die 3 are provided with upper convex pressing edge die guide columns 4; the upper convex pressing edge die guide column 4 moves up and down in the lower groove edge die guide groove 5; spring compression columns 10 are arranged on two sides of the lower end edge face of the upper convex pressing edge die 3; the shape and the size of the cross section of the spring compression column 10 are the same as those of the groove on the limiting panel 9, and the lower end face of the spring compression column 10 penetrates through the groove on the limiting panel 9 and is in contact with the spring contact plate 8.

The front and rear side walls of the lower groove cutting die 2 are provided with arc-shaped cutting surfaces opposite to the lower end arc-shaped cutting surface of the upper convex cutting die 3.

The shapes of the groove in the middle of the buffering module shell 6, the spring contact plate 8 and the groove in the limiting panel 9 are circular at one end and rectangular at the other end.

During use, a pipe is placed in the arc-shaped blade face of the lower groove blade die 2, the upper convex blade die 3 is driven by the hydraulic driving mechanism to cut the pipe downwards, the upper convex blade die 3 continues to move downwards due to inertia, the spring compression column 10 extrudes the spring contact plate 8 in the process, the spring 7 is compressed, the downward movement of the upper convex blade die 3 is buffered by the compression of the spring 7, and the arc-shaped blade face of the upper convex blade die 3 is prevented from directly contacting the bottom of the lower groove blade die 2. In the process, the upper convex pressing edge die guide column 4 moves up and down in the lower groove edge die guide groove 5, so that the upper convex pressing edge die 3 is prevented from moving in a staggered mode in the horizontal direction (namely, the guide effect is achieved).
