The thickness of the bite plate should be within the specified range of various specifications. If it is less than the minimum thickness, it will be prone to crack and wrinkle.
If the thickness is greater than the maximum thickness, due to the square of the thickness of the plate, it will cause the abnormal damage of the forming roller wheel, the overload of the transmission system and the failure of the boring car, due to the obvious increase of bending force.
The processing power of the
pittsburgh lock former machine is designed according to the ordinary steel plate, and the commonly used ordinary thin steel plate, galvanized steel sheet and plastic composite steel plate have good bite forming performance.
The strength of stainless steel plate should be higher than that of ordinary steel plate. Before using the stainless steel plate, it is necessary to make the forming experiment to avoid overloading the equipment and causing excessive wear or mechanical accident.
Due to the poor plasticity of the aluminum plate, it is easy to crack when the bite is formed, and the forming test should be done before the construction. Meanwhile, due to the lack of elasticity of the aluminum plate, the aluminum duct can not carry out the snap bite.
Before the use of the pittsburgh lock former machine, the commissioning of the feeding guide shall be adjusted strictly according to the equipment's commissioning requirements, and the feeding guide shall be adjusted to the specified position size and fixed.
If the actual position of the feeding guide is less than the specified position, the bite is not formed.
If the size is greater than the specified position, the size of the bite is too poor because the feed is too wide, causing two plates to be unable to bite or waste material;
If the feeding guide is skewed badly, it is easy to produce the deviation of the uneven width of the bite.
