The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of combined type cutting tool for polyethylene spirally enwound structure-wall tube bell and spigot is provided, have be convenient to manufacture, cost is low, for ease of maintenaince, advantage such as low, the long service life of noise.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of combined type cutting tool for polyethylene spirally enwound structure-wall tube bell and spigot, it is characterized in that: constitute by tool rest and blade, tool rest is shaped on along the circumferential direction uniform a plurality of axial blade erecting bed by tubular matrix and outer surface thereof and is constituted, and a plurality of removable blades all are installed on each axial blade erecting bed at interval.
And the blade that adjacent shaft is installed on the blade erecting bed is interlaced layout.
And, on each axial blade erecting bed, being shaped on bolt mounting holes, blade all is fixedly installed on each axial blade erecting bed by fastening bolt.
And, on the tubular matrix of a side of each axial blade erecting bed, all being fixed with compact heap by fastening bolt, each blade clamps and is installed between axial blade erecting bed and the compact heap.
And described axial blade erecting bed is shaped on 6-10 at the outer surface circumference uniform distribution of tubular matrix, and the blade number of being installed on each axial blade erecting bed is 4-9.
And the outer surface of described axial blade erecting bed and tubular matrix all is the angle of 6-10 degree.
Advantage of the present utility model and beneficial effect are:
1. this process tool adopts blade and the removable combination mounting means of tool rest, the processing and manufacturing process of tool rest is more simplified, and the little making of blade, low cost, and can use the standardized product parts, can change cutting tip at any time, it is very convenient to keep in repair, and significantly reduces maintenance, maintenance cost, and overall use cost can reduce more than 50%.
2. this process tool is by installing the mode of blade at tool rest upper edge axially spaced-apart, the cutting face contact area of blade and processed tubing is reduced, thereby the vibrations that can effectively reduce in the working angles to be produced, not only can improve cutting precision, and it is little to have a noise, it is low to wear and tear, advantages such as long service life.
3. the utility model is simple in structure, design science is reasonable, have the processing and manufacturing of being easy to, advantages such as cost is low, easy to maintenance, cutting precision is high, long service life, be a kind of combined type cutting tool for polyethylene spirally enwound structure-wall tube bell and spigot that has than high innovation character, in plastic pipe processing, be with a wide range of applications.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of combined type cutting tool for polyethylene spirally enwound structure-wall tube bell and spigot, constitute by tool rest and blade, tool rest is shaped on along the circumferential direction uniform a plurality of axial blade erecting bed 2 by tubular matrix 1 and outer surface thereof and is constituted, and a plurality of removable blades 3 all are installed on each axial blade erecting bed at interval.The blade of being installed on the adjacent axial blade erecting bed is interlaced layout, to guarantee cutting precision.The fixed form of blade and axial blade erecting bed can for: be shaped on bolt mounting holes at interval on each axial blade erecting bed, blade all is fixedly installed on each blade erecting bed by fastening bolt 4.The fixed form of blade and axial blade erecting bed also can for: on the tubular matrix of a side of each blade erecting bed, all be fixed with compact heap 5 by fastening bolt 6, each blade clamps and is installed between blade erecting bed and the compact heap, this mounting structure has anti-loosing effect, can guarantee the Tool in Cutting processing effect.Axially the blade erecting bed is shaped on 6-10 at the outer surface circumference uniform distribution of tubular matrix, and being shaped in the present embodiment is eight axial blade erecting beds.The blade number of being installed on each axial erecting bed is that 4-9 (can revise) is individual, is preferably 7.
Axially blade erecting bed and the outer surface of tubular matrix are the angle of 6-10 degree, and optimum is 8 degree, and the technical purpose of this structure reduces the stressed of blade for improving cutting precision, prolongation blade service life.
