Tiger head shears operators must be familiar with the main structure,performance and application methods of the shears.
Tiger head shears are suitable for cutting various steel plates,copper plates,aluminum plates and non-metal material plates whose material thickness is the rated value of the machine tool,and it must be materials free of hard marks,welding slag,slag inclusion,and welding seams.Excessive thickness is not allowed .
The operator of the tiger head scissors must be used according to the process above the clarification book. Generally speaking, the method of use is as follows:
1.Adjust the blade gap according to the thickness of the material to be cut.
2.Adjust the master or fixture according to the width of the cut data.
3.Make 1,3 idle strokes before operating the machine tool,and then cut operation can be performed after normal.If the shearing machine is found to work abnormally during operation,immediately block the power supply and shut down for inspection.
With the rapid growth of the world's population,the consumption of textiles is also rapidly increasing,resulting in a shortage of textile raw materials and a substantial increase in prices.On the other hand,a large amount of waste textiles are directly buried and incinerated as garbage,which not only causes a waste of resources,but also pollutes the environment.Therefore,the recycling and reuse of textiles can not only save a lot of resources,but also reduce the environmental pollution caused by the textile industry.It also conforms to the situation of social development and meets the requirements of the scientific development concept;it is also a resource-rich and low-
investment,Emerging industries with significant benefits can not only alleviate the current situation of resource shortage in the textile industry,the recycled old clothes can also be transported to third world countries for further use by local residents,which has huge economic and social benefits.
There are two main sources of waste textiles,one is from the blanking,leftovers,waste yarn,waste cloth,etc.produced in each process of spinning,weaving and finished product processing.Others are old clothes,old carpets,etc.
2.Check whether the coaxiality of the plunger pump and the engine is out of tolerance: the plunger pump and the engine are installed differently,so that the plunger pump and the drive shaft are subjected to radial force, and the coaxiality is readjusted.
3.Check that the movement of the servo piston and the variable piston is not flexible,and occasional or frequent pressure fluctuations occur:if it is an occasional pulsation,it is mostly caused by oil and dirt stuck in the piston.The dirt can be washed away and normal ,You can clean and change the oil at this time.If it is frequent pulsation,it may be due to strain or awkwardness of the mating parts.At this time,the parts should be removed for research and distribution or replaced.
2.When the hydraulic system is designed,it can also reduce the change of the liquid flow rate by shortening the length of the pipeline,reducing unnecessary bends,or adopting a hose that has the effect of removing the impact force,so as to help when the reversing valve is closed.Reduce instantaneous pressure to prevent hydraulic shock.
3.In the hydraulic system,in response to the hydraulic shock caused by the sudden braking of the moving parts in high-speed motion,the treatment measures are to set a buffer device at the end of the cylinder,or use a reduction valve at the end of the cylinder stroke to relieve the hydraulic shock.The installation of accumulators in the hydraulic system or the use of rented rubber hoses with shock absorption capacity can also reduce the hydraulic shock.
2.The equipment has a high degree of automation,and only one person can complete the production;
3.The equipment is under high pressure and the finished product has high density.Whether it is steelmaking or casting,it can reduce production costs,and there will be no slag drop or break during transportation;
