First, the scope of application:
1. Scope of application of tensile testing machine: Tensile testing machine is also called tensile machine. It is mainly used for various physical and mechanical properties of plastic sheet, pipe, profile, plastic film and rubber, wire and cable, waterproof coil, wire and other materials. Test, tensile machine is used for mechanical reinforcement of tensile and compression, bending, shearing, peeling and other mechanical properties of metal materials and non-metal materials. The tensile machine fixture is an important part of the instrument, and different materials need different The fixture is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results is high or low.
2. Scope of application of peeling force testing machine: suitable for plastic film, composite material, soft packaging material, plastic hose, adhesive, adhesive tape, self-adhesive, medical patch, protective film, release paper, combination cover , metal foil, separator, back sheet material, non-woven fabric, rubber, paper fiber and other products such as stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, opening force, low speed unwinding force, dialing Performance tests such as force.
Second, the structure principle:
1. Tensile testing machine structure principle: The tensile testing machine consists of one or two vertical carrying columns and a liquid crystal display. The supporting column is mounted on a fixed horizontal base with a movable horizontal beam at the top. In most of today's electronic tensile machines, the struts are typically driven by a lead screw to determine the position of the moving beam.
The specifications of the tensile tester are expressed by the combination of the maximum load that the frame can withstand and the maximum load of the load cell. The load unit is mounted on a motor driven or hydraulically driven moving beam. The load cell connected to the fixture measures the force and can be read from a digital display or computer. Many electronic tensile testing machines have interchangeable sensors that match the material to be tested.
2, peeling force testing machine structure principle: the horizontal structure, high-precision gear reduction electronic speed motor drag load chuck, load performance is stable. The whole machine is composed of a drag motor, a main body casing, a microcomputer controller, a micro printer, etc., and the force measuring unit is composed of a high-precision force value sensor and a digital control system using a single chip microcomputer as a central processing unit.
