The inventor finds that after a tire body is cut into 3-4 cm rubber blocks, the rubber blocks are usually coated with vulcanized rubber and internally provided with high-strength steel wire meshes, and no matter the rubber blocks are recycled for the purposes of blending concrete, proportioning asphalt pavement, filling rubber products, preparing regenerated rubber and the like, the rubber blocks are firstly coarsely crushed into 5-mesh rubber blocks, then the rubber blocks are further finely crushed into 10-12-mesh rubber particles, and steel wires are simultaneously separated: and in the coarse crushing stage, namely 3-4 cm rubber blocks are crushed into 5-mesh rubber blocks, and in the fine crushing stage, namely the 5-mesh rubber blocks are further crushed into 10-12-mesh rubber particles. In the fine crushing stage, the crushed 5-mesh rubber block contains fine steel wires, the mechanical efficiency of the shearing processing mode is highest, but the shear blade is preferentially suitable for crushing high-strength steel wires, so that the surface hardness of the shear blade needs to be improved, and a sufficient chip breaker groove needs to be designed, the shear blade is not easy to wear and radiate heat in time, and the surface carbonization of rubber particles due to high temperature is avoided.
The inventor finds that an open type double-roller crusher is adopted in a tire body rubber block fine crushing machine, a shear blade on the roller surface of a roller is a cutter bowl group, the cutter bowl group transmits torque to the roller through a round key, the cutter bowl group is formed by combining 20-30 cutter bowls, each cutter bowl is formed by two flying shear disks, each flying shear disk is designed to be of a high-low order, the high-order part of each flying shear disk is provided with 4 sections of shear tooth blades, the shear tooth blades are uniformly distributed with 6-8 chip breaking grooves, the low-order part of each flying shear disk is provided with a ring-shaped anchor and an anchor rope saddle, the ring-shaped anchor is divided into two areas, a tensioning end anchor hole and a fixed end upset anchor hole are respectively designed, one Ø 3 prestress high-strength steel wire penetrates through the tensioning end anchor hole and surrounds the cutter bowl for one circle, then penetrates through the fixed end upset anchor hole for cold heading to form an upset anchor rope, prestress ring-shaped anchor rope is applied after an anchor clamp is installed in the tensioning end anchor hole, two prestressing force ring-shaped anchor ropes are tightly solidified into one cutter bowl, a pair of cutter bowls, and the cutter bowls oppositely rotated on the roller surface, and the cutter bowls are opened and closed in a reciprocating mode, and the cutter bowl.
The inventor finds that the shear blade on the roller surface of the fine crushing toothed roller is preferentially suitable for crushing high-strength steel wires, and the situation that the shear blade is broken easily occurs due to the fact that the shear blade bears larger impact force and extrusion force and also needs to balance larger torque during shearing, so that the design of the prestress annular anchor rope enables two flying shear discs to be tightly solidified into a cutter bowl.
The inventor finds that 20CrMnTi forge pieces are adopted as flying shear discs, after finish machining, carbonitriding heat treatment is carried out, the surface hardness is HRA56-60, the core hardness is HRC25-28, two flying shear discs are sequentially assembled into a cutter bowl, the annular anchor of one flying shear disc is selected as a prestress applying platform, a Ø 3 prestress high-strength steel wire sequentially penetrates through a tension end anchor hole of the selected annular anchor and then penetrates through a fixed end heading anchor hole of the other flying shear disc along an anchor rope saddle, namely, the Ø 3 prestress high-strength steel wire penetrates through the fixed end heading anchor hole of the selected annular anchor after surrounding the cutter bowl for one circle, the steel wire is subjected to cold heading into a round heading by a hydraulic cold heading machine, then an anchor clamp is installed in the tension end anchor hole, anchor removing grease is evenly coated, prestress is applied by using a through hydraulic jack, the applied prestress is 60% of the strength of Ø 3 prestress high-strength steel wire, the two flying shear discs are tightly solidified into a cutter bowl, then the cutter bowl is sequentially penetrated into a cutter bowl group, and a cutter bowl group is connected by a high-and a cutter bowl group key.
Compared with the prior art, the invention at least has the following advantages: the shear blade on the roller surface of the fine crushing toothed roller is preferentially suitable for crushing high-strength steel wires, and the material with high hardness and high strength for shearing the high-strength steel wires is easy to break, because the shear blade bears larger impact force and extrusion force and also needs to balance larger torque during shearing, so that a pre-stress annular anchor cable is designed to tightly and fixedly connect two flying shear discs into a cutter bowl.
