[CN 201721488823.9] Automatic shear limiting device for billet shearing machine


[CN 201721488823.9] Title of an automatic shear limiting device for billet shearing machine: Application number of an automatic shear limiting device for billet shearing machine: CN 201721488823.9 Applicant: Fuzhou Kangford Machinery Equipment Co., Ltd. Application date: 2017-11-9 Patent type: Utility model The utility model relates to the technical field of steel smelting production equipment, especially to an automatic shear limiting device for billet shearing machine, the limiting device is placed between the fixed shear sheet and the sliding shear sheet of the shearing machine, the limiting device includes a main body, an upper limiting rod and a lower limiting rod, the upper limiting rod and the lower limiting rod Both are nested in the main body through a reset spring, and the outer ends of the upper limiting rod and the lower limiting rod are correspondingly connected with the two ends of the main body through a positioning bolt cover, the exposed end of the upper limit rod is connected with the limit signal end circuit of the shearing machine, and the exposed end of the lower limit rod is connected with the common signal end circuit of the shearing machine. The overall limit device adopts the upper limit rod and The lower limit rod is combined with a reset spring and a rigid structural member, which can maintain its structural stability in a high temperature environment, is not easy to cause jam or deformation, is convenient and reliable, and has high stability, to ensure that the shear machine reliable limit processing operations.
