hydraulic shearing machine Primary risk

A Shearing machine is a machine that cuts metal sheets into different standard blocks according to production needs. The shearing machine has upper and lower blades. Generally, the lower blade is installed on the worktable, and the upper blade reciprocates to cut. The maximum thickness and width of the blank that can be cut by a particular shearing machine and the strength limit value of the blank are restricted, and the machine may be destroyed if used beyond the limit. The cutting edge of the shearing machine is very sharp, and the fingers operated in the operation are very close to the cutting edge, so improper operation will cause serious incidents such as cutting fingers.

2. Security measures

(1) Before operation, carefully check whether all parts of the shearing machine are normal, whether the electrical equipment is intact, whether the safety protection device is reliable, and whether the smooth system is unblocked, and then add lubricating oil, test drive, and test cutting before it is used. When two or more people are working together, it is necessary to confirm that one person is in command, and the machine tool can only be cut when the table and the surroundings are obstructed.

(2) The shearing machine is forbidden to cut two different standards and different materials together. It is forbidden to cut without material. The surface of the cut sheet must be flat, and it is forbidden to cut the narrow sheet that cannot be compressed.

(3) When operating the shearing machine, be concentrated, your fingers should be 200mm away from the knife edge when feeding, and should be separated from the pressing device. During feeding and reclaiming, the steel plate should be avoided from scratching, and the steel plate should not be cut off and hurting people. The foot switch should be equipped with a solid protective cover to prevent heavy objects from falling on the foot switch or stepping on it by mistake. It is forbidden to refuel or adjust the machine when driving. hydraulic shearing machine

(4) All kinds of shears should be adjusted appropriately according to the thickness of the regular shears to avoid accidents caused by improper use.

(5) The brake of the shearing machine should be checked frequently to ensure it is reliable, avoid the brake loosening, and prevent the upper knife from falling down and hurting people.

(6) The sheet material and the cut strip have sharp edges and sometimes burrs, so avoid scratches.

(7) In the operation process, use safe hand tools to complete the operations of feeding, positioning, picking up and sorting leftovers, etc., to avoid fingers being injured by the mold. hydraulic shearing machine

3. Safe operation of shears

1. Add grease according to the equipment lubrication regulations before starting, check the oil quantity and quality of the oil cup, and cover the oil cup hole cover;

2. Before work, the upper and lower blades should be set. The blade gap should be determined according to the thickness of the sheared steel plate, generally between 5 and 7% of the thickness of the sheared plate. Every time the gap is adjusted, the flywheel should be turned by hand Make the upper and lower blades reciprocate once, and use a feeler gauge

3. According to the requirements of frying and cutting workpieces, loosen the bolts of the positioning stopper, adjust the size and position of the positioning stopper, and open it to be firm. Before working, you should try dry running for 2~3 times to confirm that the lubrication is good and there is no abnormal operation before working: hydraulic shearing machine

4. It is forbidden to use percussion to tighten the stopper or adjust the blade gap. When adjusting the gap between the guide rail and the knife edge, stop the machine before proceeding. It is forbidden to enter the cutting area by hand or pick up and pick up materials by hand during the working process;

5. The blade edge must be kept sharp. If damage, wear or dullness is found, it should be sharpened or replaced in time; operation hydraulic shearing machine

6. When cutting sheets of different thicknesses and different materials, the pressure of the plate spring and the blade gap should be adjusted appropriately to prevent the spring from collapsing

7. It is forbidden to cut bar materials, and no other items are allowed on the worktable to avoid entering the cutting edge and damaging the blade:

8. It is forbidden to blank over-length, over-thick, high-speed steel, tool steel and cast iron that have been cut and quenched;

9. Pay attention to whether the pull rod fails, whether the fastening screw is firm, and the fingers cannot enter the knife edge when feeding, and it is strictly forbidden for two people to be on the same machine at the same time

10. Stop in time at the end of work, cut off the power supply, wipe the machine tool, and clean up the environment;

11. The clutch should be disengaged before starting, and the motor is not allowed to start with load:

12. Before starting the machine, cut before the empty car test, and can only process after the empty car test is normal;

13. Adjust, repair and clean equipment: it must be shut down.
