Description
Technical Field
The utility model relates to the technical field of pressing tools, in particular to a convenient heat-proof coating tensile-shear strength test piece pressing tool.
Background
The tensile-shear strength is a test for checking the performance of the heat-proof coating, test piece pressing is required to be carried out before the test, the existing test piece pressing is mostly manually carried out for gluing, and then weights or pressing blocks are used for pressing two test pieces. Because the coating is smooth, the two test pieces are easy to slide and laterally shift and misplace, and when the two test pieces are stretched towards two sides by using a stretcher after bonding, the two stretching forces are not in a straight line, so that the stretching value is easy to be smaller than a qualified index, and the false appearance of unqualified coating performance is caused. However, if the test piece is placed on the platform for pressing, because the length of the test piece is longer (100 mm) and the bonding position is 15 mm, the test piece positioned above the test piece is suspended downwards by 85 mm, if the test piece is not padded, the test piece is inclined, if the pad is too high, the test piece is also inclined upwards, the force is not in a straight line during stretching, and the numerical value is smaller.
When the coating test piece is manufactured manually, the phenomenon of adhesion and skewness often occurs, so that the pressed test piece is unqualified, the test piece needs to be cured for at least 3 days when one-time pressing is carried out, the time is long, and if the test piece is unqualified, the test piece pressing manufacturing needs to be carried out again, so that the subsequent production progress is influenced. In addition, the human eye has visual errors, and when the test piece is adhered, whether the test piece is adhered or not cannot be distinguished. Therefore, the market urgently needs to develop a novel portable heat-proof coating pulling-shearing strength test piece pressing tool to solve the existing problems.
