Description
Technical field
The present invention relates to a kind of brief test device testing fluoroplastic internal lining pipe anti-wear performance.
Background technology
Fluoroplastic are general names of various fluoropolymer, typically refer to monomer autohemagglutination containing fluorine atom or with other not fluorine-containing unsaturated monomer copolymerization and obtained polymkeric substance.Fluoroplastic have the excellent properties such as chemical inertness, high-low temperature resistant and self lubricity, are widely used in the fields such as Aero-Space, automobile, machinery, chemical plant, electronics and biomedicine.
In recent years along with the development of automobile industry, the consumption of the automobile zip using fluoroplastic as internal lining pipe goes from strength to strength.And for the performance index of automobile zip with fluoroplastic internal lining pipe, external industry standard is ASTM D638-2003(American Society Testing and Materials) version.Wherein relate to the detection method of the pulling strengrth and breaking elongation etc. of product, and corresponding detecting instrument is also substantially all more complete.
But, relating to internal lining pipe anti-wear performance context of detection, also there is no corresponding instrument on the market at present, not finding this relevant pick-up unit through retrieval yet.
Summary of the invention
In order to solve now on the market still not about the problem of automobile internal lining pipe anti-wear performance pick-up unit, the invention provides a kind of brief test device detecting internal lining pipe anti-wear performance, being eliminated the error of manual operation by exemplar, counterweight and stationary installation thereof, Frequency Converter Control speed and eccentric wheel adjustment stroke, is a kind of standardized wear-resisting pick-up unit
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of fluoroplastic internal lining pipe wear resistance testing device, comprise push-and-pull lock core clamping system, abrasion system and measuring system composition, zip core clamping system comprises push-and-pull lock core, metal frame, eccentric wheel and tension side, one end of push-and-pull lock core is fixed in metal frame, metal frame drives reciprocable by eccentric wheel, and the push-and-pull lock core other end passes tested exemplar and fixes with tension side; Abrasion system comprises eccentric wheel, motor, metal frame, disk and push-and-pull lock core, fluoroplastic internal lining pipe to be tested walks around disk, push-and-pull lock core is through fluoroplastic internal lining pipe to be tested, two ends are fixed respectively, motor drives eccentric wheel to rotate, and drives metal frame to-and-fro movement thus the fluoroplastic internal lining pipe pulling push-and-pull lock core to wear and tear to be tested; Measuring system comprises metal frame, sensor sum counter, and the reciprocal time of metal frame is sent to counter by sensor, carries out record by counter.
Described tension side is weight or extension spring.
Described weight is counterweight.
The disk of described clamping system is two, and fluoroplastic internal lining pipe to be tested becomes S shape to walk around two disks respectively.
The circumference of described disk is provided with groove, and fluoroplastic internal lining pipe to be tested walks around the groove of disk.
Described motor is also connected with frequency converter.
The invention has the beneficial effects as follows: devise an internal lining pipe wear-resistant tester easy and simple to handle, filled up the vacancy that current internal lining pipe anti-wear performance detects; More accurate internal lining pipe anti-wear performance can be detected by exemplar stationary installation, stroke adjusting device, robot scaler.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
1. metal frame; 2. counterweight; 3. iron block; 4. rosette; 5. eccentric wheel; 6. sensor.
Embodiment
Refer to Fig. 1, one embodiment of the invention comprises push-and-pull lock core clamping system, abrasion system and measuring system composition, zip core clamping system comprises push-and-pull lock core, metal frame, eccentric wheel and tension side, one end of push-and-pull lock core is fixed in metal frame, metal frame drives reciprocable by eccentric wheel, and the push-and-pull lock core other end passes tested exemplar and fixes with tension side; Abrasion system comprises eccentric wheel, motor, metal frame, disk and push-and-pull lock core, fluoroplastic internal lining pipe to be tested walks around disk, push-and-pull lock core is through fluoroplastic internal lining pipe to be tested, two ends are fixed respectively, motor drives eccentric wheel to rotate, and drives metal frame to-and-fro movement thus the fluoroplastic internal lining pipe pulling push-and-pull lock core to wear and tear to be tested; Measuring system comprises metal frame, sensor sum counter, and the reciprocal time of metal frame is sent to counter by sensor, carries out record by counter.
Described tension side is weight or extension spring.
Described weight is counterweight.
The disk of described clamping system is two, and fluoroplastic internal lining pipe to be tested becomes S shape to walk around two disks respectively.
The circumference of described disk is provided with groove, and fluoroplastic internal lining pipe to be tested walks around the groove of disk.
Described motor is also connected with frequency converter.
Automobile-used fluoroplastic internal lining pipe usually and push-and-pull lock core with the use of, therefore be screwed in metal frame with one end of push-and-pull lock core, the other end passes tested exemplar and fixes with counterweight, by the iron block welded together with base plate, exemplar is fixed, exemplar walks around the groove of smooth metal disk with S shape, driven by motor eccentric wheel rotates, thus make zip core and internal lining pipe do reciprocating friction to move, regulate motor speed to adjust zip core by frequency converter and internal lining pipe does the reciprocating friction period of motion.Sensor sensing metal frame reciprocal time feeds back to counter and record.By observing or arranging induction installation at the corresponding site of fluoroplastic internal lining pipe, determine its degree of wear, arrive data when specifying the degree of wear, be the anti-wear performance data of corresponding fluoroplastic internal lining pipe.
Concrete, counterweight can be substituted by other weight or extension springs etc., but counterweight is more accurate for the control of the tension force of this proving installation.
Concrete, motor is selected and is regulated motor speed by frequency converter, better can carry out adjusting rotary speed according to the actual service condition of product, the abrasion condition better under simulation using state, be that the result of test is more close to the wearing and tearing under actual service condition.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, also can make some improvements and modifications, these also should be considered as protection scope of the present invention.
