(5) specific embodiment
With reference to Figure of description 1 to 3, plastic extrusion products cutting mechanism wherein illustrated in figures 1 and 2 comprises:
The feeding clamp mechanism drives described tool rest and does feed motion;
Described cutter is anodontia dise knife, and the blade angle of this cutter when being the single face sword be 3～6 degree, blade angle 4～12 degree during for double knife-edge.
Here, said drive unit and feeding clamp mechanism can adopt present cutting machine the version that generally adopts, certainly, forms of motion at drive unit described in this programme and feeding clamp mechanism has more selection, promptly consider the structure and the area of section material section, it is main still based on cutting movement selecting with the feed motion.
For the selection of described cutting edge, therefore this programme may tend to the cutter that cutting edge has double knife-edge feed motion partly as cutting movement because of considering, cutting effect can be better, and used cutting force is less.And the single face sword is simple in structure, is convenient to processing, for when being main motion with the cutting movement, is a reasonable selection.
In addition, for the selection of blade angle, under the situation that guarantees cutting edge strength, the smaller the better, the population angle is more little, and the section defective is more little, except this factor, also needs to consider the section structure and the area of section bar.Division is as follows:
Said section structure and area, the present plastic material that generally uses, area is less, under room temperature (20 degrees centigrade) condition, according to checking, double-sided blade adopts 2.5 degree of minimum, even 1.5 degree, under the higher 500r/min condition of cutting speed, 500 situations that tipping can not occur of continuous cutting-off.Under the same terms, the cutter of said single face sword can have essentially identical effect.Consider that conversely improving the section bar temperature, and the cutting edge of wide-angle is just arranged, said feed motion just can be as main motion, for the less section bar of cross-sectional area, cutting movement can be selected the 20r/min than low speed.For the bigger situation of blade angle, more need to consider be at the bigger section structure of section material section area than complex situations, principle remains under the situation of having considered cutter life, the population angle is as far as possible little.
Further, the temperature of section bar when considering cutting is under the perfect condition, need be with reference to Vicat softening point, the sample that so-called Vicat softening point refers to polymer such as engineering plastics, general-purpose plastics is in liquid heat-transfer medium, under certain load, certain constant heatingrate's condition, by 1mm
2The temperature of pressing when being pressed into the 1mm degree of depth.When cutting big section section bar, needed section bar temperature should have reasonable cutting effect, and can not produce gross imperfection more than 1/4th respective material Vicat softening points, below three/one dimension card softening point.
On the principle, in cutting process, need certain temperature as subsidiary conditions, in fact, its temperature is up to 200 degrees centigrade behind the extruder extrusion profile, though just arrive cutting work station through station afterwards, the temperature that himself kept can fall within the above-mentioned temperature range basically, thereby this programme can play good cutting effect in actual use.
Nature as noted earlier, for the smaller section bar of cross dimensions, can cut at normal temperatures, still can obtain reasonable effect.
Based on above statement, this programme is preferred: the blade angle when described cutter is the single face sword is 3 ~ 4 degree, blade angle during for double-sided blade is 4 ~ 6 degree, following position for these two scopes can not produce the situation of the quick inefficacy that causes because of tipping in bigger temperature (20 ~ 80 degrees centigrade) and section bar type scope.In this, this programme still tends under the situation that guarantees cutter life, adopt the less cutting edge of angle as far as possible, following position cutter corresponding to 3 ~ 4 degree and two angular ranges of 4 ~ 6 degree has higher service life, and following some position can obtain current receptible cross section quality, all can satisfy the specification requirement of cutter life and cross section quality in this scope.
In cutlery is selected, cutter thickness need be considered cutter diameter and blade angle, cutter diameter most importantly wherein, and therefore the thickness of described cutter is 2 ~ 10mm, this number range and cutter diameter adopt conventional selection mode, are linear relationship with blade diameter promptly.
For the version of described tool rest, one can adopt hinge to be installed in swing span on the described support, its two can select with vertically be arranged on described support on the movable stand that moves up and down that cooperates of big guide shaft 2.Nature, those skilled in the art can also select other kinematic pair.
Described drive unit is the reductor of motor and configuration, and the output shaft of this reductor is equipped with described cutter.In addition, simple for some section structures, and the less section bar of cross-sectional area, can adopt the cutter of straight line sword, in cutting process, sword line direction upper knife edge and section bar do not have relative motion, just can finish cutting.
This cutting mechanism also comprises the lubricating arrangement that is arranged on the described tool rest, and the lubricating grease so that described Tool in Cutting to be provided reduces the damping in the cutting process, and folder cutter phenomenon, improves cutter life.
Correspondingly, in order to cooperate above-mentioned plastic extrusion products cutting mechanism, used cutter is anodontia dise knife, and its blade angle when the single face sword is 2 ~ 6 degree, blade angle 4 ~ 12 degree during for double knife-edge.
