The embodiment of the invention provides an angle steel equal-distance automatic discharging device, and relates to the technical field of angle steel discharging, the angle steel equal-distance automatic discharging device comprises a base, supporting legs are fixedly installed at the four corners of the top of the base, and buffer conveying mechanisms are fixedly installed at the positions, located on the inner sides of the supporting legs, of the top of the base; when the discharging frame moves to the top or the bottom, a first linkage plate and a second linkage plate at the bottom of a connecting frame make contact, the connecting frame is propped open through mutual abutting of inclined faces, sliding blocks are driven to move outwards to enable clamping plates to be separated, and after clamping plates in the discharging frame at the top are separated, angle steel automatically falls into the discharging frame; the driving gear and the gear ring drive to enable the discharging frame to displace, after separation, the limiting spring resets to push the sliding block to drive the clamping plate to move inwards to clamp the angle steel, the bottom discharging frame is similar, the angle steel can be automatically discharged, stable conveying displacement and equal-interval discharging are integrally achieved, the discharging stability is improved, the angle steel is prevented from being damaged, and the quality is improved.
