Understand the precautions before the operation of the hydraulic ironworker combined punching and shearing machine
In the process of using the hydraulic hydraulic ironworker combined punching and shearing machine, some failures may occur sometimes. We can correctly analyze the reasons for the failures, which is the premise and basis for problem solving. Now let’s take a closer look at what are the reasons for the failure of the equipment, and understand these actual situations in a targeted manner, which will have more guarantees for solving problems in the future.
On the one hand, the failure of the hydraulic hydraulic ironworker combined punching and shearing machine may be due to the quality of the equipment itself, so the service life will be very short. There are many different kinds of equipment on the market. Some products are of good quality, while others are not so good. Therefore, in the process of purchasing, don’t be greedy for cheapness, but choose carefully and buy better quality products. Good equipment, which reduces the occurrence of failures in the process of use.
On the other hand, in the process of using the hydraulic hydraulic ironworker combined punching and shearing machine, the use environment and the specific operation method will have a certain impact on the equipment. Use it in an appropriate environment and use a more suitable operation method, so as to reduce the occurrence of some faults, so as to truly ensure a better effect in the process of use. Different faults have different causes. After careful analysis, future use will be guaranteed.
Understand the precautions before the operation of the hydraulic ironworker combined punching and shearing machine
Precautions before the operation of the hydraulic ironworker combined punching and shearing machine:
1) The lubrication of each transmission part should be sufficient, and each lubrication point should be refueled 2-3 times per shift;
2) The shearing and punching dies should be intact without cracking and fastened firmly;
3) The gap between the punch and the wall of the die hole should be uniform and meet the requirements of punching and shearing, and the punch configuration should slightly exceed the plane of the die hole;
4) The equipment is electrically insulated and well grounded. The operation steps of the hydraulic hydraulic ironworker combined punching and shearing machine test run. The dial indicator is fastened on the slider, so that the probe of the dial indicator is on the inspection surface of the square. As the slider moves down, it checks in two mutually perpendicular deflections. The difference between the readings on the dial gauge is the error of the verticality. The stroke length is 25 to 50mm, 0.04 to 0.08; Put the dial gauge probe on the surface of the inspection rod; when the slider moves down, inspect in two mutually perpendicular directions.
The reading difference on the dial indicator; the value is the error of parallelism; the stroke length is less than or equal to 25mm>25～50mm>0mm. Fasten the dial indicator on the outer end of the upper tool holder, so that the dial indicator can measure the top of the head; The vertical support surface where the blade is attached; when the upper tool holder moves down, check the reading difference on the dial gauge; it is the error of parallelism. Shear thickness ≤ 10mm at 100mm stroke length; shear thickness > 10mm On 100mm stroke length;
The hole on the punch holder to fasten the punch, the parallelism of this middle line to the movement of the slider is 0.040.060.08; the vertical support surface that fits with the lower blade; the parallelism to the movement of the upper tool rest; 0.05 to 0.160. 05～0.24 Note: When the upper tool holder moves downward, the distance between the two verticals that fit the upper blade and the lower blade; only the vertical support surface that fits the upper blade can be increased; the parallelism of the movement of the upper tool holder ;
Put the dial indicator on the outer end of the workbench, so that the dial indicator can measure the top of the head; on the vertical support surface that fits with the upper blade; check when the upper tool holder moves down. The reading difference on the dial gauge is the error of parallelism. The shear thickness is less than or equal to 10mm at 100mm; the stroke length is: shear thickness > 10mm at 100mm stroke length: the hydraulic ironworker combined punching and shearing machine uses a feeler gauge to check both ends The gap between the blades; the small difference is the error of parallelism.
Preparations before the hydraulic ironworker combined punching and shearing machine work
The hydraulic ironworker combined punching and shearing machine is a machine tool that integrates various functions such as metal shearing, punching, plate shearing and bending. It has the advantages of easy operation, low energy consumption and low maintenance cost. It is a modern manufacturing industry (such as: Metallurgy, bridge, communication, electric power, military and other industries) metal processing equipment of choice. hydraulic ironworker combined punching and shearing machine is divided into hydraulic hydraulic ironworker combined punching and shearing machine and mechanical hydraulic ironworker combined punching and shearing machine. Today, I will explain to you the preparations before the joint punching and shearing machine works.
- Before starting the hydraulic ironworker combined punching and shearing machine, check whether the driving parts of the punching and shearing machine and the connecting screws and pins of each part are loose, and whether the electrical grounding is in good condition.
10 correct opening methods of hydraulic ironworker combined punching and shearing machine
- Before working, lubricate all parts of the hydraulic ironworker combined punching and shearing machine, and start the machine for two to three minutes. No problem can be put into work.
- Overloading is not allowed, and punching and shearing of quenched steel is strictly prohibited.
- When operating the hydraulic ironworker combined punching and shearing machine, you should wear gloves and labor protection articles, and sandals and slippers are strictly prohibited.
- When the hydraulic ironworker combined punching and shearing machineis punching and shearing, it is necessary to always refuel the punching tools to prevent the upper and lower punching tools from being skewed.
- Pay attention to the safety of fingers when feeding the hydraulic ironworker combined punching and shearing machine, especially when the sheet is rushed to the last presser foot and cannot press the sheet, it is forbidden to punch and shear.
- It is strictly forbidden to disassemble, proofread the cutting edge and punching die when starting up. Do not beat dies, cutting blades and other parts with force.
- Strictly control the specification range of the sheet, and it is strictly forbidden to punch and cut when it exceeds.
- The workplace must not accumulate other items and a large amount of flushing materials, and must stop when adjusting and cleaning.
- After the work is completed, the hydraulic ironworker combined punching and shearing machineshould be shut down and powered off in time, and the site should be cleaned up.
