How to operate the shear safely?

1 shear

1.1 check whether the material and thickness of the sheet are in accordance with the drawing, whether the surface of the plate is uneven and defective, pay attention to the direction of the grain 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 stop, and check whether the cut material is accurate and whether the width of the two ends is the same.

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

1.4 the cut sheets shall be placed by category, stacked in a regular manner, marked with the title and size, so as to protect the board surface from damage.

1.5 when cutting small pieces of sheet metal, it must be cut after the pressing column of plate shearer, and pay attention to the safety of operation.

  1. How to use plate shears

2.1 after the plate shears are started, several idling cycles are carried out to ensure that the plates with different thickness (t ≤ 6 mm) are cut under normal conditions, and the functions of the plate shears are understood.

2.2 it is necessary to adjust the blade clearance before cutting the plate. If the corresponding blade gap is not adjusted, the blade durability will be affected.

2.3 in the process of shearing, open the pressure gauge to investigate the oil pressure. When cutting 1.0 mm stainless steel plate, the pressure should be less than 1.5 MPa. It is not allowed to cut the plate with thickness greater than 6 mm in violation of regulations to avoid damage to the machine tool!

3 operation 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 beyond the function.

3.2 before starting the equipment, add oil according to the smooth rules of the equipment and check the oil volume of the oil 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 shear steel plate. Generally, it is between 8-10% of the thickness of the plate to be cut, and each gap adjustment should be locked and adjusted according to the thickness of each plate. (refer to the gap adjustment reference table on the machine tool)

3.4 during the operation, it is forbidden to wipe the machine tool and the worktable, and it is not allowed to place sundries or things on it, so as to prevent the blade from being damaged by the edge of the pushing blade. It is necessary to avoid material rebound when pressing material.

3.5 always pay attention to the abnormal or failure of locking organization, gathering and scattering, braking and foot switch, and concentrate on cutting. In case of abnormal equipment phenomenon, stop cutting immediately, cut off power supply and inform maintenance personnel for maintenance.

3.6 according to the relevant rules, pay attention to safe and civilized production and keep the surrounding environment clean.
