Product Name:  Dumbbell-shaped hydraulic sample preparation machine
Product introduction
Mobile forces on the machine is mainly used for pressing sheet material standard sample, by the host, hydraulic cylinder, hydraulic pressure source and the corresponding tooling mould, wherein, the host using the framework of the whole steel plate processing, good rigidity, the structure is simple, operation is convenient. The hydraulic source use three-phase motor drive high-pressure oil pump safety valve limits the maximum pressure, the manual reversing valve oil change, namely the piston rod downward pressure shear motion and to reset action, when the electric reversing valve in normal operation when the valve core is in the middle position, the piston stops moving. The hydraulic oil pressure resistant to shock pressure indicator, such as replacement of mold or other attachments, but also can be used as a general press, expand the use of functions.
YZY-I dumbbell-shaped hydraulic sample preparation machine
1. YZY-I can meet the requirements specified in the GB/T228.1< metallic materials tensile testing at ambient temperature > sample preparation, equipment can according to the mold will sample a pressing automatic stop, the sample falls on the platform, the specimen surface smooth without scratches, peripheral without burrs.
2. There is enough good strength and toughness of the specimen mold, pressing can bear the pressure of 300KN without damage, the mould adopts the high quality alloy material, not easy to wear, high service life;
3. The sample mold can be replaced conveniently, each update time is less than 10 minutes, accompanied with a die set (attached drawings);
4. The equipment can be finished by one person to operate independently, the operation process of a key, a sample preparation time is less than 1 minutes;
5. all the spare parts of the equipment are easy to buy, can provide on-site repair service in 24 hours;
