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;
