Crucible pulling knife device

Abstract

The invention relates to a crucible drawing knife device. The crucible drawing knife device comprises a crucible drawing knife body which is of a hollow cylinder structure, wherein the cylinder wall of the crucible drawing knife body is provided with an upper-down penetrated crucible drawing knife body section groove; the crucible drawing knife body section groove is internally fixedly provided with a sleeve ring, the sleeve ring is internally sleeved with a rotating shaft, the bottom of the rotating shaft is movably connected with an arc-shaped rotating rod, and the top of the rotating shaft is movably connected with a rotating handle; the end part of the arc-shaped rotating rod is provided with a drawing knife head, and the length of the arc-shaped rotating rod is not less than the length of the radius of the crucible drawing knife body which is of a hollow cylinder structure; when the crucible drawing knife device is used, firstly the crucible drawing knife body is inserted into a crucible for one time, a material is longitudinally packed, and then the rotating handle is rotated; the rotating handle drives the rotating shaft to rotate, the rotating shaft drives the arc-shaped rotating rod to rotate, the arc-shaped rotating rod can do a circling motion by surrounding the rotating shaft, the drawing knife head is utilized for cutting off the bottom surface of the packed and sleeved extracted material, the crucible drawing knife body is taken out, and the material is pulled out.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a crucible knife removal device. Background technique [0002] In the processing of materials, the knife is often used. According to the length of the material to be processed, the handle of the knife can be properly processed and then welded to the knife head, and the material can be hollowed out at one time. But will draw out the shape of crucible with drawing out knife, existing drawing out knife tool can not realize this function. [0003] Therefore, it is simple to produce a kind of structure, easy to operate, work efficiency is high, the crucible knife device that pulls out the crucible shape material once and has broad market prospect. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a crucible knife removal device with simple structure, convenient operation, high work efficiency, clean material without residue, and ...
