In the use process of the existing chopper, the cutting edge is in direct contact with the high-temperature forging piece, so that the stress is large, the stress condition is complex, and the abrasion of the chopper is serious; although the chopper uses high alloy steel materials, the service life of the chopper is short under the working condition of high temperature and high stress, so that the chopper consumes a large amount in production. At present, the kitchen knife is basically formed by integrally forging high-performance alloy steel materials, and if the cutting edge of the kitchen knife is worn to a certain extent, the whole kitchen knife is scrapped, so that great waste is caused. Therefore, it is an urgent need to develop new special-purpose choppers and to improve the service life of the choppers.

Detailed Description

The following description fully illustrates the specific embodiments of the utility model to enable those skilled in the art to practice and reproduce it.

FIG. 1 is a schematic diagram of a double-edged chopper for a large free forging hydraulic press according to the present utility model; FIG. 2 is a schematic view of the structure of the cutter body according to the present utility model; FIG. 3 is a schematic diagram of the structure of the chopping knife holder of the present utility model.

Double-edged chopping knife for large-scale free forging hydraulic press includes: a chopper body 1 and a chopper seat 2,

the chopper body 1 includes: the upper and

lower cutting edges

11, 12, the lifting holes 13, the supporting

plate

14, 15, the upper and

lower cutting edges

11, 12, 14 are connected between the two supporting arms 15, the supporting plate 14 is connected between the upper and

lower cutting edges

11, 12, and the upper and

lower cutting edges

11, 12 are respectively provided with a plurality of lifting holes 13.

The thickness of the cutting edges of the upper and

lower cutting edges

11, 12 is smaller than the thickness of the cutter body, and the longitudinal included angle between the two side wall surfaces of the upper and

lower cutting edges

11, 12 is 5 degrees. The lifting hole 13 is used for lifting and installing, and the supporting plate 14 is used for bearing pressure during working and plays a role in protecting the upper cutting edge 11 and the lower cutting edge 12; the supporting arm 15 is of a regular hexahedral structure, and the height of the supporting arm 15 is slightly higher than that of the upper and

lower cutting edges

11 and 12, so as to bear the pressure during working and protect the upper and

lower cutting edges

11 and 12.

The chopping blade holder 2 includes: the chopping knife seat body 21 and the lifting lugs 22 are respectively arranged on the outer walls of the two sides of the chopping knife seat body 21; the chopper seat body 21 is provided with a U-shaped opening 23 at the top, and a mounting groove 24 is provided on the inner wall of the U-shaped opening 23.
