How to operate the shearing machine safely?

　1 cut

　　1.1 Check whether the material and thickness of the sheet are correct as shown in the figure, whether the sheet has unevenness, defects, pay attention to the grain direction, and confirm the cutting sequence.

　　1.2 Adjust the gap between the upper and lower cutters according to the thickness of the plate, adjust the position of the back gauge, whether the cut material is accurate, and whether the width of the two ends is the same.

　　1.3 In the process of cutting, it is often checked whether the size of the cut sheet (length, width, diagonal) conforms to the drawing.

　　1.4 The cut sheets should be sorted and placed, stacked neatly, and marked with the title and size to protect the surface of the board from damage.

　　1.5 When cutting small pieces of sheet material, it must be done after the pressure column of the shearing machine can be cut, and pay attention to the safety of the operation.

　　2 How to use the shearing machine

 cnc processing

　　2.1 After starting the shearing machine, make a few cycles of idling to ensure that sheets of different thickness (T≤6mm) are tested under normal conditions and understand the function of the shearing machine.

　　2.2 It is necessary to adjust the blade gap before trial cutting. If the corresponding blade gap is not adjusted, the durability of the blade will be affected.

　　2.3 Open the pressure gauge to investigate the oil pressure during the shearing process. The pressure should be less than 1.5Mpa when cutting 1.0mm stainless steel plates. It is not allowed to cut sheets with a thickness greater than 6mm illegally to avoid damage to the machine tool!

　　3 Operating procedure

　　3.1 It is necessary for the operator to understand the general structure and function of the equipment, and it is forbidden to use the equipment with super functions.

　　 3.2 Before starting the equipment, add oil according to the smooth rules of the equipment and check the oil volume of the cylinder.

　　3.3 The upper and lower blades should be adjusted before operation, and the blade gap should be confirmed according to the thickness of the sheared steel plate. Generally, it is between 8-10% of the thickness of the cut sheet. Each gap adjustment should be locked and adjusted according to the thickness of each sheet. (Refer to the gap adjustment control on the machine tool for the adjustment comparison table)

　　3.4 During the operation, it is prohibited to wipe the machine tool, and no debris or objects are allowed to be placed on the workbench to prevent the blade from being damaged by the blade. When cutting the material, the pressing plate must be pressed tightly to avoid the material rebound and hurt people.

3.5 Always pay attention to whether there are abnormalities or malfunctions of the locking organization, gathering and dispersing, braking, and foot switch. When cutting, you should concentrate your energy. If the equipment is abnormal, stop cutting immediately, block the power supply and notify the maintenance personnel for maintenance .

　　3.6 In accordance with relevant rules, pay attention to safe and civilized production, and the surrounding environmental sanitation.
