Multi-hole type bending material receiving table of numerical control sawing machine

Abstract

The invention relates to the technical field of numerical control machining equipment, and discloses a multi-hole type bending material receiving table of a numerical control sawing machine. The material receiving table comprises a bottom box, an operation box is fixedly mounted on the left side of the front surface of the top of the bottom box, a machining table is fixedly mounted at the top end of the bottom box, a cutting assembly is movably connected to the inner wall of the top end of the bottom box, and a fixing column is fixedly mounted at the top end of the cutting assembly. According to the multi-hole type bending material receiving table of the numerical control sawing machine, in the cutting process of a saw blade, a top plate and an accessory structure of the top plate are shrunk into the inner wall of the saw blade, meanwhile, a touch ball is also shrunk, after a workpiece is completely cut off, the top plate is not subjected to the force of the workpiece, and then a springback rod drives the touch ball to reset towards the outer side, at the moment, the supporting force of a torsion spring is smaller than the moving force of an edge grinding ball, the torsion spring rotates, meanwhile, a baffle changes the position and shrinks, then the edge grinding ball extends to the surface of the saw blade, and when the saw blade moves upwards, the edge grinding ball makes contact with the surface of the workpiece and removes burrs, and then the edge grinding ball moves to the original position along with the saw blade.

Description

technical field [0001] The invention relates to the technical field of numerical control processing equipment, in particular to a porous bending material receiving table of a numerical control sawing machine. [0002] technical background [0003] CNC sawing machine is a kind of equipment for cutting steel pipes and plates. The machining accuracy of CNC sawing machine is generally not very high. It is mostly used in the material preparation workshop to cut various bars, pipes and other profiles. The driving wheel and the driven wheel drive the saw blade to run, and the cutting direction of the saw blade is controlled by the guide rail control frame. After the band saw blade is adjusted straight through the adjustment of the self-rotating bearing, the steel pipe is cut off by the sweeper. [0004] However, the general CNC sawing machine often has the following two defects in the processing process: [0005] 1. After the CNC sawing machine cuts the workpiece, because the saw b...

Problems solved by technology

[0005] 1. After the CNC sawing machine cuts the workpiece, because the saw blade of the CNC sawing machine moves downward, when the saw blade is separated from the workpiece, burrs will appear on the surface of the workpiece. When people move the processed workpiece, even if they wear protective gear Gloves will also be pricked by burrs, which is very unsafe;

[0006] 2. When the workpiece is piled up too high or the height of the workpiece itself is too large, the general saw blade will extend downward to cut the steel pipe. If the saw blade extends, its own toughness will decrease, and it will easily cause the saw blade to break and collapse. A broken saw blade may cause fragments to the operator and equipment, which has a very high safety hazard
