Description

Technical Field

[0001] The utility model belongs to the technical field of precision four-column hydraulic cutting machines, in particular to a cutting device for precision four-column hydraulic cutting machines. Background Art

[0002] The cutting machine is an indispensable equipment in some light industries. According to the traditional concept, the cutting machine is a machine that uses the force of the machine movement to pressurize the cutting die to perform punching processing on non-metallic materials.

[0003] When using the existing cutting machine, the staff usually needs to place the metal material on the cutting table. Since the cutting table is fixed and the up and down moving distance of the cutting knife is fixed, when thicker materials need to be cut, the cutting will not be complete. When cutting thinner materials, the cutting knife will not be able to contact the material, thus affecting the production of metal materials. Therefore, we proposed a cutting device for a precision four-column hydraulic cutting machine. Utility Model Content

[0004] The purpose of the utility model is to provide a cutting device for a precision four-column hydraulic cutting machine. By setting a lifting platform, specifically, rotating the handle to drive the rotating rod to rotate, the bevel gear 2 drives the threaded rod to rotate through the bevel gear 1, and the annular threaded block drives the lifting cylinder to move upward or downward, and the lifting platform is lifted and lowered to adjust the height of the cutting platform. The required height can be adjusted according to materials of different thicknesses to achieve better cutting effects and avoid incomplete cutting. This solves the problem that when the existing cutting machine needs to cut thicker materials, incomplete cutting will occur, and when cutting thinner materials, the cutting knife will not be able to contact the material, thereby affecting the production of metal materials.
