Technical Field

The utility model relates to the field of industrial glue testing equipment, in particular to a preparation tool for a drawing performance test spline.

Background

The most important index parameter of the adhesive is the bonding performance, namely the bonding strength of the adhesive at a bonding interface. The method for measuring the bonding performance mainly comprises a shear force test and a drawing force test, wherein the shear force is parallel to the bonding material, and the drawing force is perpendicular to the direction of the bonding material. In a general test method GB/T6329-1996, two aluminum sample strips are bonded together, the thickness of the cured adhesive is kept uniform, then a drawing test is carried out, the drawing performance of industrial adhesive is also influenced by the adhesion position and uniformity, in the spline preparation process, the butt joint pulling head is required to be kept horizontal and vertical, and meanwhile, the thickness of the bonded adhesive is required to be kept uniform.

The existing mode of adhering industrial glue is that a group of splines needing to be adhered with the industrial glue are fixed in a limit groove of a butting block, then the butting block is moved to enable the splines to contact the gasket with the splines, and then the gasket is taken out to smear the industrial glue, but the method can only adhere a group of splines each time, meanwhile, in the process of moving the butting block, the splines are easy to twist and misplacement, the spline bonding surface is difficult to be guaranteed to be aligned completely, or only one drawing spline with glue thickness can be prepared, drawing splines with different thickness requirements cannot be prepared, and the thickness of the cured adhesive is difficult to be guaranteed to be uniform and meet the test thickness requirements.
