9. The swing mould to form bottom have water cooling device.
10. The sliding table with scraper (mould) have thickening function .the scraper can run more than once at horizontal and vertical on the basis of setting parameters in the touch screen at any time
11. Location mode of workpiece adopts the back of the positioning for product conformance The positioning length can be manually adjusted according to the requirements .
12. By replacement of the tooling, mould and adjusting the process parameters, can be quickly implemented different specification products.
13. That machine is for bottom forming and bottom pushing. If you want to save cost, you can also use the machine to form the mouth when you change the moulds. But it is inconvenient to change moulds.
Bottom pressing machine
1. The max pressure for bottom pressing: 150Ton
2. The max traveling distance for bottom pressing: 150mm
3. Main structures: the bottom pressing machine consists of the main frame, inner mould driving
and reversing device, auxiliary tightening device, rotating V-frame etc...
4. Main features: machine main body adopts 4-column structure; the moulds are made from
3Cr2W8V; different sizes of cylinder requires different thickness V-frame, sleeves, and inner and outer mould.
5. The max length of the tube can be 1250mm.
The main structure can be seen as above. The machine is used to press the bottom after the bottom is formed. Working process: workpiece will enter the V-frame from last process, mandrel pushing cylinder will push the workpiece to the front by pushing the mandrel, the slide actuating cylinder push the gate to the opening of the mandrel, after that, the oil cylinder push slide block to drive the out-die work,and return after forming the bottom. slide actuating cylinder make the gate open,mandrel-push&pull-cylinder drive the mandrel to reset,then the flip cylinder rise up ,the flip V-rack flips through the flip hinge frame,the last,the workpiece is sent to the feeding rack.

Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
