Production mold for adhesive tape for steel wire adhesive force test sample and method

Abstract

The invention discloses a production mold for an adhesive tape for a steel wire adhesive force test sample. The production mold comprises cut-off knives, connecting rods and a plurality of partition plates, wherein each partition plate is fixed onto the connecting rod, and one cut-off knife is fixed between any two adjacent partition plates. The invention also relates to a method for producing the adhesive tape by utilizing the mold. The method comprises the following steps: two connecting rods respectively penetrate through two connecting holes in the partition plates, the partition plates are connected with an airflow, the cut-off knife is placed between two partition plates, and a nut is screwed down so as to fix the partition plates and the cut-off knife to form a mold; an adhesive piece which is preliminarily prepared, is discharged by an open mill and has a standard thickness is placed on a flat cutting plate after clean liner plastic cloth is attached to each of two sides of the adhesive piece; one side, with the cut-off knife, of the mold is placed onto the adhesive piece, and the mold is pressed until the cut-off knife cuts off the adhesive piece; the mold is removed, and the cut adhesive tapes are separated for later use. By adopting the production mold and the method, multiple groups of test samples can be cut in one step, and the working efficiency is greatly improved; moreover, the cut-off knife and the partition plate can be replaced freely, so that convenience, rapidness and high efficiency can be realized.

Description

technical field [0001] The invention relates to a mold for making rubber strips required for steel wire adhesion test samples, and also relates to a method for making the required rubber strips by using the mold. Background technique [0002] At present, when the steel wire adhesion test sample for tires is made, the rubber material is usually pressed out of a film of required thickness with an open mill, and then the size of the required rubber strip is drawn on the film, and then the glue is cut out with scissors. Finally, the rubber strips are stuffed into the mold and covered with steel wires for vulcanization. The production efficiency of this method rubber strip is very low. According to the requirements of the national standard, the width of the rubber strip is generally 12.5mm, 25.0mm, etc. Taking the cutting of the 12.5mm wide rubber strip as an example, using the traditional method of drawing lines and cutting, each rubber strip takes about 1min and consumes Time...
