Q11 series mechanical brake plate shears

Q11 series mechanical brake type plate shearing machine is composed of bed, knife rest, transmission, clutch brake, pressing material, blocking material, lubrication other parts. The bed is of high quality steel plate welding structure, with good rigidity high strength.

Main structural features

1. This machine is a mechanical shearing machine. The upper tool carrier moves up down. The bed is composed of left right columns, worktable, upper crossbeam, platform movable worktable. The bed stiffness is good, the bed is required to be stable under load.

2. The machine body adopts all steel plate welding structure, which can effectively eliminate the stress by vibration aging annealing, so as to ensure that the machine tool has high static dynamic stiffness shock absorption performance, that the accuracy of the machine tool can be maintained for a long time.

3. The sliding block (upper tool rest) is an integral welding structure of plate weldment. The swing shear movement is realized within a certain angle range around a fixed circle center through the transmission of connecting rod crankshaft; the blade clearance is adjusted to worm gear structure, the scales are set on both sides of the bed respectively, the zero position limit function is also provided. The blade clearance can be adjusted within 2-3 minutes.

4. The transmission system adopts the first-class belt drive the second-class gear drive, with reasonable transmission layout convenient maintenance. In the process of shear transmission, it has shear overload protection function to prevent overload shear workpiece damaging the equipment.

5. The structure of the machine should be compact, its main principle is composed of motor → flywheel → clutch / brake (friction type) → gear mechanism → spindle → upper lower movement of upper tool rest; traction electromagnet hydraulic drive clutch is adopted; the friction plate of clutch brake is required to domestic famous products with reliable quality.

6. The equipment should have a strong mechanical pressing system, the pressing force should be large enough, there should be no movement of sheet metal during shearing. The fence type safety protection device is installed at the pressing system to prevent the operator entering the cutting edge by hand.

7. The transmission rotating parts are equipped with safety protection cover to ensure that the safety performance of the equipment meets the national requirements.

8. The blade material can meet the following plate shear: carbon steel, 1Cr20Ni14Si2, 0cr23ni13, 1Cr18Ni9Ti. The blade is delivered after flaw detection.

9. The double button switch controls the shearing operation has the functions of inching, single operation continuous operation. It is equipped with safety protection device of electrical interlocking, which meets the national safety standard.

10. It is equipped with infrared ray line-up device, which is convenient for scribing shearing.

11. Centralized automatic control is adopted for equipment lubrication, which is composed of oil pump, distribution valve pipeline. If there is oil shortage in lubricating parts, automatic alarm will be given. The lubrication is manual multi-point dry oil pump lubrication, the oil distribution can be completed by the oil separator, the lubrication performance is reliable.

12. Cam oil pump pressure device, through the cam pump body piston movement to achieve the pressure action. Eight pressing feet are installed on the bed (above the worktable), the pressing force can be adjusted according to the thickness of the shearing plate, so as to ensure reliable compaction shearing accuracy.

13. Manual blocking device, the baffle plate can be lifted up to realize longitudinal infinite shear.

Exclusion method of plate shears:

1. Ask the equipment operator to understand the operation status of the hydraulic system of the hydraulic shear. It includes: whether the hydraulic system of the shear works normally; whether the hydraulic pump has abnormal phenomenon; the time result of the hydraulic oil detection cleanliness; the cleaning replacement of the filter element;

Whether the hydraulic components have been adjusted before the failure; whether the sealing elements have been replaced; what abnormal phenomena have occurred in the hydraulic system of the shear before after the fault; what faults have occurred in the system in the past how to eliminate them need to be understood one by one.

2. Look at the actual working condition of the hydraulic system of the shear, observe whether there are problems in the pressure, speed, oil, leakage vibration of the system.

3. Listen to the sound of the hydraulic system of the shear, such as: impact sound; pump noise abnormal sound; judge whether the hydraulic system works normally.

4. Touch the temperature rise, vibration, crawling the tightness of the joint to determine whether the working state of the hydraulic system of the shear is normal.
