First of all, the surface of the cutter board should not be uneven, and the joint of the door and the cover should be leveled. All components shall be internally lapped and painted, and the painted surface shall be smooth, uniform in color and free from wrinkles and appendages. Secondly, the transmission gear should be greased again. Move the cutter board by hand to check whether each part can operate normally.

If there is no problem, you can start the high-voltage electric shock, high speed to see if it can also run, two to four hours to see if the temperature of the rolling bearing is less than 63 degrees.

Combined with punching and shearing machine and mechanical profile punching and shearing machine, it integrates punching, plate shearing, angle steel shearing, profile shearing and other capabilities. Combined with the advantages of light weight, small volume and low noise, punching and shearing machine is an ideal equipment for modern machinery manufacturers, such as metallurgy, bridge, communication, electric power and other industries.

In order to meet the needs of real production, the new combined punching and shearing machine independently designed a multi-capacity hydraulic combined punching and shearing machine, in order to reach the net surface more neat and smooth, good-looking, small rib mark, high added value.

Pollution control and purification of hydraulic oil for 3 roller plate bending machine

Pollution control and purification of hydraulic oil for 3 roller plate bending machine

1、Pollution control of hydraulic oil in 3 roll plate bending machine

The working life and reliability of hydraulic components are mainly determined by the pollution tolerance of components and the pollution degree of hydraulic oil of three roll bending machine. In order to ensure the service life and reliability of components, the pollution control measures can be taken to achieve a reasonable balance between the pollution degree of hydraulic oil and the pollution tolerance degree of key hydraulic components, which is the basic content and purpose of pollution control.
There are two ways to improve the working life and reliability of components: one is to develop pollution resistant components to improve the pollution resistance of components by improving the design parameters, structure and material of components; The second is to take pollution control measures to reduce the degree of pollution of hydraulic oil in three roll bending machine. Experience shows that the latter is a more economical and effective way.

In order to effectively control the pollution of the hydraulic system, the following measures are mainly taken: 1) cleaning the components and system, removing the residual pollutants in the process of processing and assembly. 2) Take measures to prevent pollutants from invading the system and control pollutants from outside. 3) High efficiency oil filter is used in the hydraulic system to continuously filter out the pollutants generated inside and intruded from outside.

2、 Purification of hydraulic oil for 3 roll plate bending machine

Prolonging the service life of the hydraulic oil of the three roll bending machine can not only save the cost of replacing the hydraulic oil of the three roll bending machine, but also save the oil resources. At present, due to the imperfect pollution control measures in some industrial sites, the hydraulic oil of the three roll plate bending machine in the hydraulic system is seriously polluted, which affects the normal operation of the equipment. Therefore, the method of frequently changing the oil has to be adopted. In fact, the dirty oil replaced is only polluted beyond the limit, and the physical and chemical properties do not reach the degree of deterioration. This kind of hydraulic oil can still be used after proper treatment. The experience shows that improving the cleanliness of hydraulic oil of three roll plate rolling machine through pollution control can significantly delay the deterioration of hydraulic oil performance of three roll plate rolling machine, and the service life of hydraulic oil of three roll plate rolling machine can be extended by 3-5 times. The Japanese industry has put forward that the service life of the hydraulic oil of the three roll bending machine can be extended to 10 years through the purification measures of the hydraulic oil.

Purification methodPrincipleApplication
filterThe use of porous media to filter out insoluble substances in oilSeparation of solid particles
centrifugalThe fluid can be moved in a circular way by mechanical means of separating insoluble substances with different density by using the radial acceleration generatedSeparation of solid particles and free water (centrifuge)

Advantages and basic operation of hydraulic ironworker machine

Advantages and basic operation of hydraulic ironworker machine

 

Hydraulic ironworker machine integrates intelligent mechanical equipment, mainly including metal cutting, steel plate processing, punching machine, and sheet metal bending. It is easy to use in the operation process, low energy consumption, low maintenance cost, and effectively saves the investment of assets. It is an ideal equipment for precision processing in intelligent processing industry; It is widely used in steel structure processing, hardware processing, grain machinery shell and large parts processing, thresher template support, trailer body mechanical parts processing, etc; There are many types of punching and shearing machines in the market, including hydraulic press combined punching and shearing machine, double hydraulic press combined punching and shearing machine, etc; The equipment is compact in structure, superior in performance, exquisite in appearance, convenient in use and safe in use;

In the operation process of the hydraulic ironworker machine, the first step is to check the switching power supply, and the next step can be carried out when the air switch is intact and the working voltage is stable; Next, open the equipment wiring cabinet for wiring, and then close the cabinet door tightly; Step 4: step on the foot switch. If the device doesn’t respond, switch the power supply of the switch when the emergency stop button is turned off; Then, the power needs to be cut off when the grinding tools are removed and replaced. Finally, after the work is finished, turn off the switching power supply and remove the slag.

How to reduce the noise of Hydraulic punching and shearing machine

How to reduce the noise of Hydraulic punching and shearing machine

1. Ensure that the combined punching and shearing machine is always in good technical condition.
2. Ensure the integrity and reliability of the working parts of the punching and shearing machine. In particular, the exhaust pipe should be installed well, because most of the exhaust pipes are equipped with silencers, which will reduce a large part of the noise.
3. Prevent the parts from loosening, which will cause vibration.
4. Do a good job in the maintenance and inspection of the combined punching and shearing machine. Add qualified lubricating oil and grease according to regulations to prevent dry friction or semi dry friction caused by poor lubrication of relative moving parts and increase noise.
5. Keep good fit clearance relative to moving parts. The driver must assemble or adjust according to the technical requirements.
6. Do not change the oil supply quantity at will. If the fuel supply volume becomes larger, the fuel injected into the cylinder will not burn completely, which not only wastes the fuel, pollutes the air, but also increases the noise of the tractor.
The oil supply advance angle should be adjusted accurately. The accuracy of oil supply advance angle adjustment not only directly affects the power of the combined punching and shearing machine, but also affects the noise of the combined punching and shearing machine. We often meet some combined punching and shearing machine in the emission of exhaust gas when the sound is particularly loud, often accompanied by “Pa, Pa” sound, this is because the oil supply advance angle is too large.
