Numerical control band sawing machine used for automatically cutting and machining complex curved surface workpieces and method

Abstract

The invention relates to the technical field of numerical control band sawing machines, and discloses a numerical control band sawing machine used for automatically cutting and machining complex curved surface workpieces. The numerical control band sawing machine comprises a band sawing machine and a fixing assembly, a top frame is fixedly installed at the top end of the band sawing machine, a saw blade is fixedly installed between the top frame and the band sawing machine, and a movable telescopic rod is fixedly installed at the top end of the band sawing machine. A fixing frame is fixedly installed at the top end of the movable telescopic rod, a to-be-cut plate is clamped in the fixing frame, the fixing assembly is fixedly installed on the left side of the fixing frame, a fixing plate is fixedly installed at the left end of the fixing assembly, and the fixing assembly comprises a middle plate. In the whole cutting process of the numerical control band sawing machine, the to-be-cut plate and a plate already cut down can be fixedly clamped by the fixing assembly and the fixing plate all the time, the plate already cut down is prevented from falling off and being damaged after being cut down, the procedure that rearrangement is needed after cutting can also be avoided, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of numerically controlled band sawing machines, in particular to a numerically controlled band sawing machine for automatically cutting and processing workpieces with complex curved surfaces. Background technique [0002] CNC band sawing machine is a machine tool for sawing various metal materials. When cutting complex curved surfaces, it is necessary to move the workpiece to be cut through the clamping device, and fix the band saw to perform mobile cutting, which is convenient for the processing of complex curved surfaces. , but in this cutting method, after the cutting is completed, the cut part will fall with gravity, causing the workpiece to be smashed and damaged, and because the surface of the cut part is a curved surface during the curved surface cutting process, when moving All of these need to be re-stacked together to facilitate transportation, which increases the production process, prolongs the p...

[0002] CNC band sawing machine is a machine tool for sawing various metal materials. When cutting complex curved surfaces, it is necessary to move the workpiece to be cut through the clamping device, and fix the band saw to perform mobile cutting, which is convenient for the processing of complex curved surfaces. , but in this cutting method, after the cutting is completed, the cut part will fall with gravity, causing the workpiece to be smashed and damaged, and because the surface of the cut part is a curved surface during the curved surface cutting process, when moving All of these need to be re-stacked together to facilitate transportation, which increases the production process, prolongs the production time, and reduces efficiency

[0003] Aiming at the deficiencies of the prior art, the present invention provides a numerically controlled band sawing machine for automatically cutting and processing complex curved surface workpieces, which has the advantage that the cut part and the cutting part can always be kept together, and solves the problem of falling damage and messy stacking of the cut workpieces The problem
