Abstract
The utility model relates to pressure-stress testing equipment of a sample, and particularly relates to a pressure-stress corrosion device. According to the technical scheme, the pressure-stress corrosion device comprises a bottom plate, a vertical column, a movable plate, a bolt and a cylindrical pin, wherein the vertical column is fixed on the bottom plate by the cylindrical pin; a groove is formed in the inner side of the vertical column; the movable plate is horizontally arranged at the inner side of the vertical column; the bolt is arranged at the middle part of the bottom plate; and the movable plate moves up and down freely along the groove in the inner side of the vertical column. The pressure-stress corrosion device has the beneficial effects that force is applied on the movable plate by rotating the bolt, and is applied on the sample by the movable plate and four fulcrums on the vertical column, so that the sample is stressed by uniform pressure stress; and the screwing length of the bolt is different, the size of the force applied on the sample is also different, so that the pressure-stress testing equipment is free to control.
Description
Technical field
The utility model relates to a kind of test agent compressive stress testing apparatus, particularly a kind of compressive stress corrosion device.
Background technology
After the plastic workings such as the roll extrusion of pipe line steel process, shot-peening, the surface produces residual compressive stress.Usually will cut sample for sample is carried out the microcell electro-chemical test, and the residual compressive stress of specimen surface discharges in the process of online cutting.In order to probe into pipe line steel through the electrochemical behavior under the situation of residual compressive stress is arranged on the surface after the rolling and processing, designed a device that can be used for the microcell electro-chemical test and sample be applied compressive stress.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and provide a kind of and can be used for the microcell electro-chemical test and sample is applied the compressive stress corrosion device of compressive stress,
Its technical scheme is: comprise base plate, column, portable plate, bolt, straight pin, by the straight pin vertical columns, described column inboard is fluted on the base plate, and portable plate lies in a horizontal plane in the column inboard, be provided with bolt in the middle of the base plate, portable plate moves along column inboard groove easy on and off.
The beneficial effects of the utility model are: by swivel bolt portable plate is applied power, four fulcrums by on portable plate and the column are applied to power on the sample, make sample be subjected to uniform compressive stress.The length difference of bolt precession, the power size that sample is applied is also different, can freely control.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the last figure: base plate 1, column 2, portable plate 3, bolt 4, straight pin 5.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises base plate 1, column 2, portable plate 3, bolt 4, straight pin 5, pass through straight pin 5 vertical columns 2 on the base plate 1, described column 2 inboards are fluted, portable plate 3 lies in a horizontal plane in column 2 inboards, be provided with bolt 4 in the middle of the base plate 1, portable plate 3 moves along column 2 inboard groove easy on and off.Straight pin 5 is nonmetallic materials, has avoided other corrosion to disturb.
During use work, bolt 4 is screwed in the base plate 1, exert pressure by 4 pairs of portable plates 3 of swivel bolt, control the size of the power that applies to test specimen by the process of moving up and down of bolt 4, be used for probing into pipe line steel through the electrochemical behavior under the situation of residual compressive stress is arranged on the surface after the rolling and processing.
