Abstract
The utility model discloses a PET board drilling tool, including the axis of rotation, encircle axis of rotation one end is provided with a plurality of blades, and is a plurality of fix jointly on the bounding wall between the knife tip of blade. Simple structure, reasonable in design, drilling efficiency is high, is worth wideling popularize.
Description
Technical Field
The utility model belongs to the technical field of the PET processing, concretely relates to PET board drilling tool.
Background
PET is mainly prepared by extruding polyester raw materials at high temperature through an extruder and extruding the extruded polyester raw materials through grinding tool openings with different calibers to obtain plates with different thicknesses. The main components of the composition comprise polyethylene terephthalate PET and polybutylene terephthalate PBT resin. The polyethylene terephthalate is also commonly called polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, together with PBT, generally referred to as thermoplastic polyester, or saturated polyester. PET and PBT are used as thermoplastic polyester together and become one of five engineering plastics.
With the widespread use of PET sheets, drilling of PET sheets has become a common way of processing PET sheets.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a PET board drilling tool to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a PET board drilling tool, includes the axis of rotation, encircles axis of rotation one end is provided with a plurality of blades, and is a plurality of jointly fix on the bounding wall between the knife tip of blade.
Preferably, one end of the rotating shaft, which is far away from the blade, is provided with a connecting piece.
Preferably, the rotating shaft is a cylindrical rod.
Preferably, the blade is of an arc-shaped structure, and one side of the blade is thin while the other side of the blade is thick.
Preferably, the blade is inclined at an angle of 15-30 degrees with respect to the axis of rotation.
The utility model discloses a technological effect and advantage: this PET board drilling cutter, simple structure, reasonable in design, drilling efficiency is high, and the blade is 15 degrees-30 degrees angle slopes with the axis of rotation and sets up for the blade can form the cutting face with the PET board, the deepening of being convenient for drill, and when drilling, the blade can form the passageway of certain distance with the axis of rotation, the discharge of the waste material of being convenient for.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention;
fig. 3 is a schematic structural diagram of the blade of the present invention.
In the figure: 1. a rotating shaft; 2. a blade; 3. enclosing plates; 4. a connecting member.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a PET board drilling tool as shown in figure 1, figure 2 and figure 3, including axis of rotation 1, encircle 1 one end of axis of rotation is provided with a plurality of blades 2, and is a plurality of fix jointly on bounding wall 3 between the knife tip of blade 2.
Specifically, one end of the rotating shaft 1 far away from the blade 2 is provided with a connecting piece 4.
In particular, the rotating shaft 1 is a cylindrical rod.
Specifically, the blade 2 is of an arc-shaped structure, and one side of the blade 2 is thin while the other side is thick.
Specifically, the blade 2 and the rotating shaft 1 are arranged at an angle of 15-30 degrees relatively slantwise.
The working principle is as follows: this PET board drilling cutter, when using, connect axis of rotation 1 on the rotating electrical machines through connecting piece 4, then it is rotatory to drive blade 2 and bounding wall 3 through axis of rotation 1, blade 2 is the slope setting of 15 degrees-30 angles with axis of rotation 1, make blade and PET board can appear the cutting face, be convenient for drill deeply, when drilling, blade 2 can form the passageway of certain distance with axis of rotation 1, the discharge of the waste material of being convenient for, bounding wall 3 can form certain drilling scope, reduce the damage of knife tip simultaneously.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
