Because the truck fork block form multifarious, thin wall and water chestnut during quenching and thin edge part of the rapid cooling surface than the surface cooling fast, resulting in the quenched and tempered to deal with stress and hardening layer around the uneven, lead to Hui parts have a lot of quenching deformation.
Numerical control quenching machine tool plant adopts different quenching substance harmful to deformation is quite large.
Numerical control quenching machine tool plant in normal temperature condition refrigeration function is very strong, not much to shape variable provisions shall be applicable to the general parts of quenching material;
While using oil as a hardening material, stipulated by quenching parts cutting performance is higher, wall thickness difference is not big, form multifarious, long process flow and multifarious;
Also USES the good rich enterprise of the sceptre to ingredients for polyethylene glycol as hardening material, when touching the hot spare parts and polyethylene glycol solution, parts surface namely accumulation is a layer of plastic film, slows down the cooling rate of the parts, and reduces the danger of parts deformation and crack.
The cold water ratio low but higher than oil, and steel after quenching is not clear and immediate quenching.
Fully considering the uniqueness of fork block structure, in order to reduce the quenching deformation of fork fork, is adopted as the hardening material.
Numerical control quenching machine tool plant adopts different quenching substance harmful to fork parts of fork is quite big.
Reason for blocking fork fork for quenching when used as a hardening material, its shape variables to consider technical standards.
Selection process did fork uneven number is 0.
22 mm, the success rate should be 95% above research the overall goals of science and technology.
Besides above outside experiments also did a lot of experiments for processing surface.
Results found that, different quenching material of slots shape variables are harmless.
Fully considering the price is more expensive, therefore slots hardening by quenching water can.
The uniqueness of fork block structure, provides manufacturing enterprises to strengthen management and handle with care, prevent parts and ensure product quality to reduce the cause of deformation.
