Process Standards of Tensile Testing Machine

Tensile testing machine is a common equipment for material testing. It is suitable for testing the mechanical properties of rubber, plastic, textile, waterproof materials, wires, cables, mesh ropes, metal wires, metal rods, metal plates, various metals, non-metals and composite materials, such as various tensile tests. By changing the attachment, compression, bending and other tests can be easily completed. All employees of Jinan Hengxu Testing Machine are in a conscientious and meticulous spirit of work and strictly control the quality. The electronic tensile test machines produced are fully compliant with the requirements of national standards and are better than national standards.

one,design

1, The tensile testing machine has a reasonable design structure, beautiful shape, easy operation and easy maintenance.

2, Fixtures and tools that ensure the performance of tensile testing machines should be supplied randomly. Accessories and tools are generally marked with corresponding marks and specifications, such as the diameter range of the sample that the chuck can hold, etc. Accessories and tools should be installed in the attachment box (bag).

3, fixtures and tools that expand the performance of tensile testing machines shall be supplied according to the agreement according to user requirements.

2. Machine processing quality, assembly and safety protection

1, processing quality

1.1The processed parts meet the drawing requirements and can only be used after passing the inspection of unqualified parts.

1.2The parts that often twist and wear on steel parts have been heat treated, and the parts after heat treatment have no cracks and other defects.

1.3The parts after heat treatment do not have annealing or blackening.

1.4After processing, there is no obvious residual magnetism in parts that are grinded with magnetic workbenches or the like.

1.5There is no mark on the machining surface and friction surface after processing.

2, assembly quality

2.1The electronic universal testing machine and its components are assembled according to the assembly process regulations.

2.2All purchased parts have a certificate of conformity and will only be used after entering the factory with a special person to inspect.

2.3All fasteners such as screws, pins, and keys are securely installed.

2.4The gear pair meshing is free of jamming or blocking, and the transformation mechanism is flexible in operation and can be positioned correctly.

3Casting processing quality

3.1The materials and mechanical properties of various castings on the tensile testing machine meet the requirements of the corresponding material standards.

3.2The surface of cast iron is flat, and the flatness of the non-machined outer surface is arbitrary600mmThe length must not be greater than3mm.

3.3The molding sand and bonds on the castings should be carefully removed, and the flashes, burrs, gates, risers, etc. need to be shoveled.
