Linear cutting tensioning balance variable mechanism

Abstract

The invention discloses a linear cutting tensioning balance variable mechanism. The linear cutting tensioning balance variable mechanism comprises an upper supporting wheel, an upper guide wheel, an upper heavy punch, a lower supporting wheel, a lower guide wheel, a lower heavy punch, a diameter measuring mechanism and a controller, wherein the upper supporting wheel and the lower supporting wheelcan be both transversely arranged on a machine body of a linear cutting machine in a sliding mode; the upper heavy punch and the lower heavy punch both comprise shells and at least two weights, wherein the shells are connected with the machine body of the linear cutting machine body, the weights are arranged in the shells from top to bottom, and the weights are connected with the weights throughelectromagnets; a steel wire penetrates through the shells and is connected with the weights on the top, the upper guide wheel and the lower guide wheel are both connected with the machine body of thelinear cutting machine; the weights of the upper heavy punch and the weights of the lower heavy punch are all connected with the upper supporting wheel and the lower supporting wheel through steel wires correspondingly, are hung on the upper guide wheel and the lower guide wheel correspondingly, and are used for providing tensioning force; a wire diameter measuring mechanism is used for measuringthe diameter of a molybdenum wire, and the controller is used for controlling the electromagnets according to the measuring result of the wire diameter measuring mechanism. The mechanism has the advantages that the service life of the molybdenum wire is prolonged, and the cutting precision is improved.

Description

technical field [0001] The invention relates to the field of wire cutting machines, in particular to a wire cutting tension equalization variable mechanism. Background technique [0002] The wire cutting machine is a kind of cutting equipment that cuts the workpiece through the stretched molybdenum wire. The existing wire cutting machine straightens the molybdenum wire through a tensioning mechanism, and the tension degree of the molybdenum wire can be adjusted by adjusting the tensioning mechanism. [0003] During the cutting process of the wire cutting machine, the loss of the molybdenum wire will inevitably occur. The loss of the molybdenum wire is directly reflected in the gradual reduction of the diameter of the molybdenum wire. At this time, the tension mechanism is not adjusted. Large, cutting operations in this case will further affect the life of the molybdenum wire, and will also affect the cutting accuracy. However, this change is difficult to find with the naked...
