1.Before starting the machine, check whether the transmission parts and connecting screws and pins of the punching and shearing machine are loose.Whether electrical grounding is in good condition.
2.Before work to the lubrication of each department, drive test for two to three minutes, no problem can be put into work.
3.No overload, no punching and shearing of hardened steel.
4.Work should wear gloves and wear good labor protection products, sandals and slippers are strictly prohibited.
5.When punching shears, we should often add oil to the punching tool to prevent the skew of the upper and lower punching tool.
6.Pay attention to the safety of the fingers when feeding, especially when the plate is rushed to the press foot can not press the plate, forbid punching shear.
7.When driving, do not disassemble, proofread the cutting edge and die.Do not hammer the punching die, cutting edge and other parts.
8.Strictly control the specification range of the sheet material, and strictly forbid punching and shearing when exceeding.
9.No other items and large amount of material should be piled up in the work place. Stop for adjustment and cleaning.
10.After completion of work, shut down and power off in time, and clean up the site.
How to reduce the noise when the combined punching and shearing machine works:
1. Ensure that the combined punching and shearing machine always works in a good technical state.
2. Ensure the integrity and reliability of the working parts of the punching and shearing machine.Especially to install a good exhaust pipe, because the exhaust pipe is mostly equipped with a silencer, it will reduce a large part of the noise.
3. Prevent loosening of parts, which will cause vibration.
4. Check the maintenance of the combined punching and shearing machine.According to the provisions of the qualified lubricating oil, grease, in order to prevent the relative movement of poor lubrication and dry friction or semi dry friction, so that the noise increase.
5. Maintain good fit clearance of relative moving parts.The driver must be assembled or adjusted according to the technical requirements.
6. Do not change the oil supply at will.If the fuel supply becomes larger, the fuel injected into the cylinder can not be completely burned, which wastes fuel and pollutes the air, and increases the noise of the tractor.
Tighten the dial gauge on the guide rod so that the top of the dial gauge is on the inspection surface of the square.When the guide rod is connected down to China, check on the two vertical points between each other.The large reading error on the dial table will be the error of flatness road length of 20 ~ 60mm0.04 ~ 0.08;In the hole of tightening the punching needle, hardware equipment is inserted into the inspection rod. A dial meter is placed on the table so that the top of the dial meter is on the face of the inspection rod.When the guide rod is connected down to China, check on the two vertical points between each other.
A large read difference on the dial;The value will be an error in flatness;The length of the journey is less than or equal to 20mm > 20 ~ 60mm BBB>m will be the dial table tightened on the outer end of the knife table, so that the dial table measuring the top of the head;The surface layer of the vertical support column wrapped with the lower blade;When the knife table is checked down to China Unicom, a large reading error on the dial table;The error of flatness will be cut thickness ≤12mm on the road length of 150mm;Cut the thickness > 12mm on the road length of 150mm;Tighten the hole of the punching needle on the punching lathe fixture, and the flatness of the middle line to the guide rod is 0.040.060.08;And the vertical support point of the lower blade edge gluten;The flatness of China Unicom on the knife table;Note: 0.05 ~ 0.160.05 ~ 0.24
The upper cutter table down China Unicom, with the upper blade and the lower blade edge of the two vertical interval;Only the vertical support point of the expansion and the upper blade edge of the gluten;The flatness of China Unicom on the knife table;Put the dial meter on the outer end of the desk so that the dial meter measures overhead;The surface layer of the vertical support column wrapped with the upper blade;Check when turning into a knife platform to China Unicom.A large reading error on the dial gauge;The error of flatness will be cut thickness ≤12mm in 150mm;The length of the road is: cut thickness > 12mm and the length of the road is: check the clearance between the two sides of the tooth surface with the feeler of the joint punching and shearing machine;Its large error, it will be the error of flatness.
