a square tube punching machine, including the rack, relative to set a number of knives on both sides of the rack base, used to determine the location of the workpiece positioning mechanism, as well as punching clamp agencies, cutter seat can be moved to set a Chong-pin, positioning the workpiece bodies, including the Central interspersed within the Feedthrough pole, xanthone, the central rod to open more than one relative with the red needle positioning holes, a number of positioning holes along the length of the direction of Feedthrough pole arrangement, Feedthrough pole The Department also has a pin hole at both ends, rack settings can be inserted under the positioning pin hole, thereby positioning rod and the workpiece can be fixed. Since the invention of the use of Feedthrough rod wear is located in the workpiece, not only the location of the workpiece, as well as to determine the location of punching and using xanthone also avoid punching the process of rod tube bending accident, so that a smooth surface tube punching , less glitches, therefore, the present invention has a high processing efficiency, processing pipe shape aesthetic advantages. Of a square tube punching machine, its features are: it includes rack (1), the relative installed in the rack as described (1), a number of knives on both sides of seat (2), used to determine the workpiece (5) red hole location of the positioning mechanism (4) and used to be processing the workpiece (5) in the axial direction on the fixed clamp body (3), as described in the knife block (2) can be moved on to set a red-pin ( *1), referred to positioning mechanism (4) includes central interlude in the workpiece (5) within the Feedthrough rod (*1), referred to in Feedthrough rod (*1) with the stated rack (1) by locking between the institution-phase locking, as described Feedthrough rod (*1) to open the middle there are multiple and Chong-pin (*1) the relative positioning holes (**1), described in a number of positioning holes (**1) along the mentioned Feedthrough rod (*1) of the length of the direction of arrangement.
