Detailed Description

As shown in fig. 1, an embodiment of the present invention provides an angle steel punching positioning device, including a hydraulic punching machine 1, a bottom die 2 and a top die 3 installed on the hydraulic punching machine 1, and a driving pair roller 4, wherein the bottom die 2 is provided with a abdicating through hole for the top die 3 to pass through, a stopper 5 perpendicular to the bottom die 2 is fixed on one side of the top die 3 on the top surface of the bottom die 2, so that two outer side surfaces of an angle steel to be punched respectively attach to the top surface of the bottom die 2 and the side surface of the stopper 5 facing the top die 3, the driving pair roller 4 includes an upper driving roller and a lower driving roller, the driving pair roller 4 clamps the horizontal part of the angle steel, so that the top surface of the lower driving roller and the top surface of the bottom die 2 keep horizontal; still include locating rack 7 and fix two sets of at least oblique wheels 8 and pinch roller 9 on locating rack 7, the slope of oblique wheel 8 sets up, and when making angle steel laminating die block 2 and stopper 5, the intersection line of two medial surfaces of angle steel is contradicted to the wheel face of oblique wheel 8, and pinch roller 9 contradicts the angle steel top surface.

The driving roller pair 4 is driven by the stepping motor 6 to realize automatic feeding of the angle steel, so that the angle steel does not need to be positioned and calibrated again when a next hole is punched after a hole is punched, and the distance between the holes is controlled by the stepping motor 6 and the driving roller pair 4; even if the angle steel is slightly deformed when the angle steel is punched by the combined action of the oblique wheels 8 and the pressing wheels 9, the punching surface of the angle steel can still be attached to the top surface of the bottom die 2, and the circle centers of all holes on the angle steel punch are located on the same straight line due to the clamping of the limiting blocks 5 and the oblique wheels 8, so that the process requirement of cross arm punching is met.
