Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.

The utility model discloses a junked rubber tire cutting tool, including polygonal cutter body 1 that has certain thickness, cutter body 1's circumferencial direction is provided with a plurality of tool bits 3, and cutter body 1 and tool bit 3 are the metal material, and each tool bit 3 is the obtuse angle setting with cutter body 1's hypotenuse 11, and cutter body 1's intermediate position department is equipped with and is used for installing at the rotatory epaxial overspeed device tensioner 2 of cutting equipment.

The beneficial effects of the utility model reside in that: the metal matrix is used as the cutter body 1, and the plurality of metal cutter heads 3 for cutting the waste rubber tires are arranged on the cutter body 1, so that dust is not generated like a resin cutting piece when the rubber tires are cut, the environmental pollution is small, and the damage to a human body is small; the cutter head 3 for cutting the workpiece is made of metal, is not easy to bond with rubber at high temperature, and has high cutting efficiency; the middle part of the cutter is provided with the tensioning device 2, so that the cutter is not easy to loosen and collapse, and has high safety.

As a preferred embodiment of the utility model, tool bit 3 is the cuboid structure, and 3 one sides of tool bit are constructed with cutting edge 32, and cutting edge 32 is 115 with 11 contained angles of the hypotenuse of cutter body 1, and the recess 13 of a plurality of and 3 adaptations of tool bit is evenly seted up to 1 circumferencial direction of cutter body, and recess 13 is located 11 handing-over departments of two adjacent hypotenuses of cutter body 1 end to end, and tool bit 3 sets firmly in recess 13. The number of the cutting tips 3 is too large or too small, which affects the cutting efficiency, and specifically, the number of the cutting tips 3 is 6 in the present embodiment. The cutting head 3 is fixed in the groove 13 of the tool body 1 by means of brazing. The edge of the exposed end part of the tool bit 3 is an arc surface 31 which is in smooth transition with the bevel edge 11 of the tool body 1. The included angle between the cutting edge 32 and the bevel edge 11 is an obtuse angle, the cutting edge enters and cuts, the cutting resistance is smaller relative to a right angle or an acute angle, the cutting efficiency is higher, and the included angle between the cutting edge 32 and the bevel edge 11 is 115 degrees in the specific embodiment. Use the cutter cutting for a long time, the passivation that tool bit 3 can become, cutter body 1 is split type structure with tool bit 3, fixes tool body 1 with tool bit 3 through brazed mode, and its stability is good, when needing to maintain or change tool bit 3, convenient and fast more. The edge of the exposed end part of the cutter head 3 is in smooth transition with the bevel edge 11 of the cutter body 1, so that the cutting resistance is further reduced.

As a preferred embodiment of the utility model, overspeed device tensioner 2 is for having the metal material of certain rigidity, including toper cover 22 and clamping ring 21, toper cover 22 and clamping ring 21 integrated into one piece have radially seted up opening 23 along it, cutter body 1 middle part seted up with the bell mouth 12 of toper cover 22 looks adaptation. When the cutting tool is installed, the tapered hole 12 of the tool body 1 is installed and sleeved on a rotating shaft of cutting equipment, then the tapered sleeve 22 is sleeved on the rotating shaft and correspondingly installed with the tapered hole 12, and the tapered sleeve abuts against the pressing ring 21 through a nut and is locked. Because the tensioning device has certain rigidity and is provided with the notch 23, under the pressure of the nut, the conical sleeve 22 matched with the conical hole 12 of the cutter body 1 can generate certain tensioning force for the cutter body 1, so that the nut and the cutter body 1 are always in a tensioning state and are not easy to loosen. When the waste rubber tire is cut, based on the characteristics of the tire, the tire is also provided with a steel wire structure, the resistance of cutting rubber is large, and a cutting tool is easy to loosen during cutting.
