Qc11y-20x4000 fast hydraulic plate shears

Qc11y-20x4000 fast hydraulic plate shears the machine structure

 

The whole machine adopts steel welding structure, wall panel, table, tool rest body and other welded parts vibration to eliminate stress, with good rigidity and stability.

 

Ii. Technology and process

 

1, this machine is a new generation of hydraulic plate shearing machine. Adopt advanced hydraulic integrated valve block. Compact structure, reduce pipeline connection, improve system reliability and easy maintenance.

 

2. The series cylinder makes the machine tool in shearing, the cylinder synchronization is good, the shearing Angle will not change.

 

3. The mounting surface of the upper tool holder is helical to ensure the uniformity of blade clearance and good quality of shear section in the shearing process. The sub-shaft supports the upper tool rest swing up and down, and the eccentric mechanism adjusts the blade clearance quickly to improve the shear accuracy.

 

4. The return of the accumulator is smooth and fast.

 

5, the upper blade is diamond, the lower blade is rectangular, the material is 9CrSi, good hardness, long life.

 

6, the upper and lower blade gap is adjusted by the handle, the dial indicates the value, the adjustment is light, fast, correct and reliable.

 

7, the tool rest stroke can be stepless adjustment, the pressure can be automatically adjusted with the thickness of the shear plate.

 

8, with light line device, electric mechanical rear stopper, and can be manually adjusted, stopper size and shear times are digital display device, easy to use.

 

9, protection grid and electrical interlocking, electrical box is equipped with a power switch and mechanical interlocking device, to ensure the safety of operation and maintenance.

 

10, work table with rolling structure, reduce sheet scratches, and can reduce friction resistance.

 

11, oil cylinder: 45 steel quenching and tempering treatment, inner hole fine boring, extrusion.

 

12, Piston rod: 45 steel quenching and tempering treatment, outer round hard chrome plating fine grinding.

i

Four, the use of hydraulic plate shearing machine:

 

1. Be careful before work:

 

1) Before the empty running test run, manual steering should be used for a working stroke, and the equipment can be started only after the confirmation of normal operation.

 

2) For equipment with hydraulic device, check the oil volume of oil storage tank should be sufficient. After starting the oil pump, check whether the valve and pipeline leak, and the pressure should meet the requirements. Open the valve to let air out of the system.

 

2. Work carefully to:

 

1), do not shear laminated sheet, do not trim the edge of the burr edge sheet, do not shear pressure is not tight narrow sheet and short material.

 

2), the gap between the knife plate should be adjusted according to the thickness of the plate, but not more than 1/30 of the plate. The knife plate should be firmly fastened, the upper and lower knife plate surfaces should be kept parallel, and manual turning inspection should be applied after adjustment to avoid accidents. [1]

 

3) The edge of the blade should be kept sharp. If the edge becomes blunt or cracked, it should be replaced in time.

 

4), when cutting, the material pressing device should be firmly pressed sheet material, not allowed to shear in the state of pressure is not tight.

 

5) For equipment with hydraulic device, except throttling and cutting, other hydraulic valves are not allowed to be adjusted without permission.

 

6), for the thickness of the hydraulic pendulum shear sheet, should be determined according to the "sheet ultimate strength and plate thickness relationship curve".

 

3, after work, the upper knife plate should fall on the bottom position.

 

Hydraulic brake type plate shearing machine before operation to wear tight protective clothing, cuffs buckle, coat hem can not be opened, not in the machine tool in operation, wear, take off clothes, or around the body, to prevent machine wound. Must wear a helmet, braid should be put into the hat, not wearing skirts, slippers.

 

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, and must be no hard mark, welding slag, slag, welding seam material, not allowed to exceed the thickness.

 

The use of plate 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; Before the operation of the shearing machine, make 1-3 empty stroke first, and then the shearing work can be implemented after normal operation.

 

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.
