Description
[technical field]
The utility model relates to plastics spiral cover technical field of performance test, specifically a kind of plastics spiral cover vertical direction performance proving installation.
[background technology]
Along with various new capability and the appearance of the plastics of function newly, increasing plastic products are widely used in household electrical appliance, automobile, electromechanics, Aero-Space, boats and ships, industry-by-industries such as commodity.A kind of as in the plastic product: plastic closure, though it is airtight by a large amount of openings that is used in various containers, but test for the various performances of plastic closure, the relevant uniform requirement that does not promptly have the world or country, the also more representative method of testing of neither one is used for the performance of the unified various plastic closures of evaluation.
At present, the country and the world is with just relating to sealing and the destructiveness of testing and investigate product with the mode of traditional torsionmeter inside the class standard, and major part can only write down the maximal value of destruction, and can not reflect corresponding process.The lid of sealing or its tangible use of similar products effect of receiving two horizontal and vertical aspect power threadably in addition, and present standard not have relevant specifically described introduction with the aspect, makes similar products test the very big uncertain factor of existence.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of plastics spiral cover vertical direction performance proving installation is provided, and goes out surrender, the inefficacy of sample, the process of destruction by the complete feedback of the writing function of omnipotent tension tester.
Design a kind of plastics spiral cover vertical direction performance proving installation for achieving the above object, comprise connect conversion head 2, go up drawing-die 3, drawing-die 6 and connect conversion head 7 down down, described upward drawing-die 3 is a cylindrical structure, described drawing-die 3 upper surfaces of going up connect upward connection conversion head 2, described drawing-die 3 lower surfaces of going up connect drawing-die 6 down, described drawing-die 6 down is a cylindrical structure, the described side of drawing-die 6 down is provided with and detects the external thread 5 that the plastics spiral cover matches, and described drawing-die 6 lower surfaces down connect and connect conversion head 7 down.
The described conversion head 2 that upward connects is provided with pin-and-hole 1, and the described conversion head 7 that connects down is provided with down pin-and-hole 8, and described upward pin-and-hole 1, following pin-and-hole 8 match with the upper and lower anchor clamps of omnipotent tension tester.
The utility model beneficial effect, novel structure, simple, strength test can be carried out at the joggled strength of vertical direction to spiral cover in the use aspect, test operability height, measured data are accurate, concrete, objective.In addition, the utility model cost of manufacture is low, and is practical, is worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a test mode synoptic diagram of the present utility model;
Among the figure: 1 is that last pin-and-hole, 2 for down connect conversion head, 8 for down pin-and-hole, 20 for omnipotent tension tester, 21 for digital guide extension meter, 22 for leading screw cover, 23 for anchor clamps, 24 is support for drawing-die down, 7 for detecting plastics spiral cover, 5 for external thread, 6 for last drawing-die, 4 for last connection conversion head, 3.
[embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in drawings, the utility model proving installation comprises connection conversion head 2, upward drawing-die 3, following drawing-die 6 reach connection conversion head 7 down, described upward drawing-die 3 is a cylindrical structure, described drawing-die 3 upper surfaces of going up connect upward connection conversion head 2, described drawing-die 3 lower surfaces of going up connect drawing-die 6 down, described drawing-die 6 down is a cylindrical structure, and the described side of drawing-die 6 down is provided with and detects the external thread 5 that the plastics spiral cover matches, and described drawing-die 6 lower surfaces down connect and connect conversion head 7 down.The described conversion head 2 that upward connects is provided with pin-and-hole 1, and the described conversion head 7 that connects down is provided with down pin-and-hole 8, and described upward pin-and-hole 1, following pin-and-hole 8 match with the upper and lower anchor clamps of omnipotent tension tester.
Method of testing of the present utility model utilizes omnipotent tension tester can realize the process simulation of stretching with certain speed, and writes down information such as corresponding displacement, power value, strained situation.Avoid the influence of other factors by the installation of vertical direction performance proving installation, fixing test sample to test process as far as possible.Set omnipotent tension tester under the situation of different displacements, sample is got different power values, the situation of simulation screw thread and edge holding capacity in opening container processes; Set omnipotent tension tester under the situation near surrender, sample is got corresponding displacement, the deformation that analog equipment is produced when bearing container inner pressure is with homogeneity and the stability of investigating its product.
The test aspect concrete steps of whole plastics spiral cover:
1, opens omnipotent tension tester, start corresponding software and hardware system and accomplish that the coupling butt joint is normal.
2, will detect the plastics spiral cover and be assembled on the described vertical direction performance of claim 1 proving installation, adjusting Power of Spin to the internal thread that detects the plastics spiral cover does not have stress with between the vertical direction performance proving installation.
3, the utilization of vertical direction performance proving installation being connected conversion head is assembled on the omnipotent tension tester.
4, use that omnipotent tension tester software is set up an office and pairing stress value and detection plastics spiral cover can bear when writing down corresponding displacement point maximum stress load.
5, corresponding test process of record and corresponding raw data, and Taking Pictures recording detects the situation of change of plastics spiral cover.
