Overview of cnc hydraulic shearing machine
Plate shearing machine is borrowed from the movement of the upper blade and fixed under the blade, the use of reasonable blade clearance, the various thickness of the metal plate shear force, so that the plate according to the size of the required fracture separation. Plate shears can be divided into: pedal type (manpower), mechanical plate shears, hydraulic pendulum plate shears and so on. Shears are often used to cut blanks with straight edges. Shearing process should be able to shear sheet material shear surface straightness and parallelism requirements, and minimize plate distortion to obtain the workpiece.
Shearing machine should be able to be shearing straightness and parallelism requirements, and minimize the plate distortion, to obtain the workpiece. The upper blade of the plate cutter is fixed on the knife rest and the lower blade is fixed on the working table. The working table is provided with a feeding ball, so that the sheet material will not be scratched when sliding on it. The rear stopper is used for plate positioning, and the position is adjusted by the motor. The press cylinder is used to compress the sheet to prevent it from moving during shearing. Guardrails are devices to prevent accidents at work.
Two, the shearing machine operation rules
Before operation, wear tight protective clothing with tight cuffs, and do not open the bottom of the coat. Do not wear, take off or change clothes beside the operating machine tool, or wrap them around the body to prevent the machine from being twisted. Wear a good hat, braids should be put into the hat, do not wear skirts, slippers.
Shearing machine operators familiar with the main structure, performance and use of shearing machine.
Plate shears are suitable for cutting all kinds of steel plate, copper plate, aluminum plate and non-metallic material plate whose thickness is rated as the machine tool. Moreover, they are the materials without hard marks, welding slag, slag and welding seam, and are not allowed to exceed the thickness.
Three, the use of shearing machine
According to the thickness of the material to be cut, adjust the gap of the blade; Adjust the die or fixture according to the width of the material to be cut; Plate shearing machine before operation for 1 & MDash; 3 times of empty stroke, the shearing work can be implemented after normal.
If the machine is found to run abnormally, the power should be cut off immediately and stop for inspection.
When adjusting the machine, cut off the power supply and move the workpiece, pay attention to the hand.
Each part of the plate shearing machine should always be lubricated, and each shift should be filled with lubricating oil by the operator once, and the rolling bearing part should be filled with lubricating oil by the mechanic once every six months.
