Shear

Shear Introduction
The sheets shear is used on the uncoiling and leveling line of sheets and it is a high-speed sheets shear designed to match the fast speed and shearing requirements of the production line. The thick sheets lines most have hydraulic high-speed shears and the thin sheets line most have electric and pneumatic sheets shears.
Shear Working Principle:
After shearing, the sheets shear shall guarantee the straightness and parallelism requirements of the shearing face of the sheared material, and reduce plate twisting as far as possible, so as to get workpieces of high quality. The upper blade of the sheets shear is fixed on the blade carrier, and the tower blade is fixed on the worktable. On the worktable, there is installed carrier roller, so that the plate material is not scratched when sliding thereon. The backgauge is used for sheets positioning, and the position is controlled by the motor. The material-pressing cylinder is used to compress the sheets, so as to prevent plate from moving during shearing.

Announcements of shear:
1.Electric shear: start the sheet shear in empty running for several cycles and ensure to try shearing sheets of different thicknesses in normal conditions, from thin to thick.
2.When shearing, different blade gaps must be correctly regulated for different sheets thicknesses, otherwise, the blade durability will be affected.
3.Hydraulic sheets shear: open the switch of the pressure gauge during the shearing process and observe the pressure value of oil line, and the pressure shall be less than 10Mpa when shearing sheets of 2mm. It is prohibited to increase the pressure for shearing sheet face exceeding the specified and thus damage the machine.
4.The sound is balanced when operating, and if the shear has noise, the machine shall be stopped for inspection.
5.When the  sheet shear is running, the increased temperature of oil tank shall be less than 60％℃, and when the increased temperature exceeds 60℃, the machine shall be stopped for rest.
