The invention discloses a multi-pass metal drawing device based on water lubrication drawing. The multi-pass metal drawing device comprises a support, a drawing cavity which is fixed in the support, a sealing ring, a mold group and a lubrication chamber group which are arranged in the drawing cavity, and a cover plate which is fixed on the support, wherein the mold group is an ultra-smooth nano diamond composite coating mold; a drawing cavity lubricant inlet is aligned with the center line of a support lubricant inlet; the sealing ring, the lubrication chamber group and the mold group are sequentially placed in the drawing cavity along the drawing direction of a pipeline material; and the opening direction of a lubrication chamber is aligned with the drawing cavity lubricant inlet and outlet. The multi-pass metal drawing device can ensure that the contact area between the pipeline material and the mold group is completely immersed in a lubricant during drawing, then the excellent water lubrication property of a diamond film is brought into play, and a drawing area is effectively lubricated and cooled, so that the service life of the mold is prolonged, and the processing surface quality and the surface smooth finish and cleanliness are improved; and meanwhile, the characteristics of safety and non-pollution of a water base lubricant also ensure that a processing environment is greatly improved.
