What problems should be paid attention to during the use of hydraulic bending machines?

1. The hydraulic bending machine does not generate pressure

1. Check whether the forward and reverse rotation of the bending machine motor and the oil pump are correct

2, clean the spool of the safety relief valve of the bending machine

3. Clean the spool of the YV1 two-position four-way solenoid valve of the hydraulic system of the press brake.

4. Check whether there is internal leakage in the large hydraulic control check valve of the bending machine.

Second, hydraulic bending machine slide block self-falling

1. Clean the spool of the small hydraulic control check valve of the bending machine.

2. Clean the spool of the lift valve of the hydraulic press brake.

3. Check whether there is leakage in the left and right cylinders of the hydraulic press brake.

Three, the two sides of the bending machine are not balanced when the plate is folded

1. Anhui Yongya CNC bending machine manufacturer believes that according to the error of the angle of the two ends of the bending machine, it can be adjusted unilaterally by using the hexagonal tube on the bending machine to disassemble one end. The Y-axis handwheel is 0.10mm. You can adjust it to a suitable state according to the size of the angle error, and connect the loose end of the hexagonal tube to the normal use.

2. Check whether there is a deviation in the free state of the two sides of the bending machine (the normal range is allowed to be 0.20-0.30mm on both sides), and the deviation value is not within the range. You can use the unilateral eccentric sleeve to adjust appropriately until the two sides are adjusted to the allowable range. use.

Safety technical requirements for CNC shears

Shearing machine is a kind of shearing equipment widely used in machining, which can cut steel plate materials of various thicknesses. Commonly used shears are divided into three types: flat shear, rolling shear and vibration shear. Flat shears are used in large quantities. Shears with a cutting thickness of less than 10mm are mostly mechanically driven, and those with a thickness greater than 10mm are hydraulically driven. Generally, single or continuous metal cutting is performed by pedal or button operation. Pay attention to when operating the shearing machine:

CNC Shearing Machine

(1) The CNC shearing machine manufacturer believes that before working, it is necessary to carefully check whether all parts of the shearing machine are normal, whether the electrical equipment is intact, and whether the lubrication system is unblocked; remove the tools, measuring tools and other debris and corner waste placed on and around the countertop.

(2) Do not operate the shearing machine by one person alone. Two or three people should coordinate feeding, control dimensional accuracy and reclaiming, etc., and be sure to have one person under the unified command.

(3) Adjust the shear gap of the shearing machine according to the specified shearing thickness. It is not allowed to cut two different specifications and different materials at the same time; it is not allowed to cut by overlapping materials. The cut sheet requires a flat surface, and it is not allowed to cut narrow sheets that cannot be compressed.

(4) The belt, flywheel, gear, shaft and other moving parts of the shearing machine must be equipped with a protective cover.

(5) The fingers of the shearing machine operator should keep a distance of at least 200mm away from the scissors mouth, and leave the pressing device. The protective fence installed on the shearing machine cannot block the eyes of the operator and cannot see the cut part. The waste generated after the operation has edges and corners, and the operator should remove it in time to prevent stab wounds and cuts.
