The invention relates to punching equipment with high stability. The punching equipment comprises a workbench, a base, a punching device and a supporting frame, and further comprises a stabilizing mechanism and two dust removal mechanisms, the stabilizing mechanism comprises a driving assembly and two stabilizing assemblies, the stabilizing mechanism comprises a first bearing, a first lead screw,a sliding block, a hinge rod, a driving rod, a lifting box, a trigger switch, an air cylinder, a piston, a driving plate, an air inlet pipe, an air outlet pipe, two connecting rods and two first springs, each dust removal mechanism comprises a power assembly, a sealing plate, an air spraying pipe and two moving assemblies, the power assembly comprises a second bearing, a power shaft, a power gearand a power unit, and each moving assembly comprises a third bearing, a second lead screw, a sleeve and a transmission gear. According to the punching equipment with high stability, the function of fixing a workpiece is achieved through a fixing mechanism, the situation that the punching precision is affected due to position deviation of the workpiece during punching is avoided, the function of removing dust from the workpiece is achieved through the dust removal mechanisms, and the situation that impurities adhere to the workpiece and accordingly punching work is affected is avoided.
