The tire shredder hammer with two different metal liquids is a bi-metal hammer. The double-metal hammer ensures the toughness of the hammer handle and the hardness and wear resistance of the hammer.
The temperature at the time of quenching of the bimetal hammer is very important. Generally, the appropriate quenching temperature is selected according to the thickness of the part wall. The higher the quenching temperature, the higher the hardenability, so it is necessary to make a reasonable calculation in the production of the hammer. Casting and heat treatment processes. If the tyre shredder hammer is not properly cast, it will cause defects such as blowholes.
When the tire recycling system of the waste tire recycling machine is not designed correctly, the eddy current generated by the molten metal will be trapped in the gas and cause the generation of pores; when the hammer is drilled, the exhaust gas is poor, and the gas cannot be discharged from the mold, which may result in the generation of the pores. We are required to strictly control the pouring temperature during casting, and evenly can not be interrupted during casting. In order to facilitate the casting exhaust, inclined casting can be used.
The tyre recycling machine hammer will have different degrees of wear after use. Due to the low impact working conditions, the surface hardening effect of the hammer head will be intensified. The wear of the hammer head refers to the metal hammer under the action of mechanical force. The surface gradually separates from the parent body, causing the performance of the hammer to change, and the wear has the greatest impact on the service life of the hammer.
