The parts of the hydraulic shearing machine need regular maintenance, in order to prolong the service life of the hydraulic shearing machine, improve productivity, the shearing machine is by the high-tech enterprises to adopt electromechanical hydraulic integration, and absorb the advantages and advantages of the traditional mechanical brake shearing. The failure of general mechanical equipment is more easily damaged parts become vulnerable parts. The failure of moving machinery often refers to the failure of wearing parts. Improve the quality and service life of wearing parts: timely update scrapped parts, is an important task to prevent accidents. The optimization design of plate shears solves the problem that swing plate shears are easy to distort when cutting narrow plates. Solve the slow down speed, noise, unreliable work and other phenomena, especially through the double nitrogen cylinder return, so that the tool rest speed increased by 30%; The frame and other main components through UG finite element analysis, so that it has good strength and stiffness; On the basis of ensuring the working accuracy and geometric accuracy of the optimized design, the material used for the product is well controlled and utilized.
1, regularly check whether there are problems with the parts of the plate shearing machine, and ensure that the wire insulation is good.
2, often check the blade edge, if the blade is passivated, to polish or replace as soon as possible, otherwise it is inconvenient to use.
3. Do not install oxygen, compressed air or combustible gas in the nitrogen cylinder.
4, the staff must fully understand the performance structure of the shearing machine, which is beneficial to the equipment and itself.
5, oil pump suction filter should be kept clean, so as not to affect the normal use.
6, hydraulic oil quantity and temperature should meet the standard, and according to the specific requirements of the hydraulic oil.
7. Check the switches, buttons and limits regularly to ensure normal use.
8. Add lubricating oil to some parts on time, so that they can start and run normally.
How to calibrate the accuracy of data bending machine? Is in fact the so-called bending machine bending machine is a kind of can be carried out on the thin plate bending machine, the structure mainly includes the bracket, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, the base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate. When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping between the pressure plate and the base plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall, the operation is also very simple. But the accuracy produced by each bending machine is not the same, today we will come to understand the problem of bending machine calibration!
Formerly, the operation of laser calibration instruments required professional metrologers. The bending machine sawing cover needs to be opened so that the optical elements can be controlled on the worktable, spindle and self-supporting tripod. The process of space calibration takes several days, depending on the size of the sawing machine. Therefore, when the workpiece is within the tolerance range as measured by the CMM, spatial calibration is not so necessary.
The trajectory of the measured target is not straight, and its lateral movement is large. Traditional reference instruments cannot do these surveys because such large lateral movements are not permitted. A single aperture laser reference instrument such as a laser Doppler displacement meter is not affected by large lateral movement. A plane mirror is used as the object to be measured. The movement parallel to the mirror will not divert the laser trip, nor will it adjust the gap from the light source.
When requirements weigh quality matters closely, alignment and offsetting directly affect cycle time. A sawing machine in the accuracy range can work at high speed while maintaining polishing accuracy. Calibration permits the on-line picking up of parts, saving the time spent moving parts between the sawing machine and the CMM. In addition, periodic calibration can also be used to predict whether the sawing machine deviates from the accuracy index.
When using a CNC bending machine picked up online, replace the dagger with a modest probe to map the proportions of the piece. The specified errors in space can be listed as error tables or offset tables so that the software can correct the coordinates of the mapped probe.
