Description

Technical Field [0001] The present invention relates to a device for testing tack of tire rubber,

The present invention relates to an adhesive force measuring apparatus for a tire semi-finished product, and more particularly to an adhesive force measuring apparatus for a tire which is capable of measuring the adhesive force of a tire rubber manufactured in the same lot while ensuring reliability, To an apparatus for measuring an adhesive force of a semi-finished product.

Conventionally, it is very important to maintain adhesive strength when making green cases for semi-finished products for tires (natural or synthetic rubber, steel cord rolled sheets, fabric cord, rolled products, etc.).

That is, if the adhesive force at the time of molding is too high, there is a large possibility of defective molding due to excessive air admission or excessive adhesive force due to excessive adhesive force between the semifinished products, and if the adhesive force is too low, stitching between semifinished products can not be performed and molding becomes difficult.

Therefore, it is very important to study the change of adhesive force when changing the process conditions of semi-finished products, and it is important that the measuring method is also adapted to actual use conditions.

However, in the conventional adhesive force measurement, a rubber rod or a rolled material sheet was prepared, and then a round bar rod made of a metal was adhered to the rubber sheet and then peeled off, and then the adhesive strength was measured. Therefore, it is different from the adhesive environment actually occurring in the tire forming process.

In the molding process of tires, the adhesion between rubber and rubber is important. Since the measuring method measures the adhesion between the steel and the rubber, differences between these materials occur. Also, when the viscosity of the rubber specimens is low, it is difficult to accurately measure the adhesion of the rubber specimens.

In order to solve this problem, Korean Patent Laid-Open Publication No. 1997-48397 discloses a method for testing the adhesion of cement for bonding both ends of a tire tread rubber by cutting the sample rubber at an oblique angle of 45 °, applying an adhesive, Discloses a test method for making tensile strength test specimens in a tensile strength tester of a rubber for a tire and testing the adhesive strength by a tensile strength test method in a general tensile strength tester. However, a separate adhesive is applied to the produced tire specimen It is not sufficient to measure the adhesive strength of the tire rubber specimen actually manufactured.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an adhesive force measuring device for a tire semi-finished product, which is capable of measuring adhesive strength of a tire rubber manufactured in the same lot while ensuring reliability, .

In order to solve the above-described technical problem, the present invention provides a seat for a vehicle, comprising: a lower plate having an upper rubber protruding hole formed therein; a side wall part fixed to both ends of the lower plate to support the lower plate; A measuring body including an upper plate provided with an elevating screw bar which is fastened to a lift hole provided in the elevating plate, and an inserting hole formed in the extension plate extending upward from the upper plate, A fixing body for fixing the measuring body, and a moving body provided on the receiving portion of the fixing body for moving the lower rubber back and forth.
