The invention provides an oblique-slip type feeding device comprising a baseplate I, a baseplate II, a bevel blanking mechanism, a product pushout mechanism and a feeding guide rail mechanism. The bevel blanking mechanism comprises a support seat I, a support seat II, a support plate I, a support plate II, a guide bar I, a guide bar II, a guide bar III, a guide bar IV and a sliding plate; the product pushout mechanism comprises two linear sliding rails, a connecting plate, at least two push rods, and a driving mechanism used for driving the push rods to do linear reciprocating motion; and thefeeding guide rail mechanism comprises a guide rail mounting block I, a guide rail mounting block II, guide rails, a guide rail cover plate I, a guide rail cover plate II, a guide plate, a sensor mounting block I, a feeding in-position detection sensor, a sensor mounting block II, a bar stock feeding validation sensor and a baffle. According to the oblique-slip type feeding device stated in the invention, not only can products be pushed into a track in sequence, but also a large quantity of products can be loaded on a slope once. In this way, not only is the cost low, but also the feeding efficiency is improved.
