Precision bar cutting machine is a kind of tool used to shear steel bar. Generally, there are two kinds of precision bar cutting machine: automatic precision bar cutting machine semi-automatic precision bar cutting machine, which are widely used in our life. But in the process of using, we must have certain technical requirements for the blade of precision bar cutting machine, so as to improve its working efficiency. What are the technical requirements for the blade of precision bar cutting machine?
1. The blade shall comply with the provisions of this standard be manufactured according to the drawings technical documents approved by the specified procedures.
2. During forging, the heating cooling speed the temperature of initial forging final forging should meet the process requirements.
3. The forging shall be free defects such as cracks, interlayer, folding, forging damage, etc. if there are such defects on the machined surface, the large depth shall exceed one-half of the processing allowance of one side at this place after removal.
4. The heat treatment of the blade should be carried out according to the process specification. The blade should have the specified strength toughness, the hardness should reach hrc50-56
5. The straightness of the machined surface of the blade shall exceed one half of the machining allowance of its section, the flatness shall exceed one half of the machining allowance of the plane, the parallelism perpendicularity between the two surfaces shall exceed one half of the corresponding dimensional tolerance of the surface.
6. The blade shall be free cracks, interlayers sharp corners, the edge shall be free defects such as chipping edge pockmarks.
7. The blades of the same type of cutter should be interchangeable.
8. The user has the right to accept the blade according to this standard. If the blade is damaged due to poor manufacturing quality within half a month the date of arrival, the manufacturer shall be responsible for replacement, except for normal wear tear.
