Description
Technical field
The invention belongs to the protective device field that cylinder moves up and down, more particularly to a kind of bringing onto load moves up and down cylinder
Protective device.
Background technology
With the development of science and technology mobile phone shell material is being constantly changing also with the upgrading of change in taste, communication signal
It.Moulding from several years ago develops to current Al-alloy parts, stainless steel part and more attractive tempered glass part.This also band
The innovation of technology is carried out.Phenomena such as in order to evade the material injustice run into processing, knife mark, fold.Grinding, polishing technology
One of necessary process is become.In view of processing efficiency and cost, grinding, polishing machine use batch machining under normal conditions
Mode produced.The grinding of the overwhelming majority, polishing machine grind product by the way that grinding medium is given to apply certain pressure
Mill, polishing.The lower pressure that this partial pressure is mainly derived from abrasive wheel dead weight and cylinder generates.Cylinder is not only played to be situated between to polishing
Matter increases stressed effect, it is also necessary to polishing medium are raised to certain position after processing, worker is facilitated to take workpiece
Put and wait other cleaning works.Polishing medium quality is differed from 100kg to 500kg, and the pushing, upper lift for continuation are contour negative
Movement is carried, the failure rate of cylinder greatly increases.Once cylinder deactivation, big quality polish medium will quickly drop, in board
There are greater risks for the life security of the personnel of operation.Patent of the present invention is applied to during being lifted on cylinder and reaches position of appearing on the stage
The safeguard protection postponed avoids personnel and equipment from coming to harm, and has extremely strong commercial application value in terms of labour protection.
Present cylinder, the main problems are as follows：
1st, present cylinder does not possess the protective device to itself mostly, once cylinder fails, powerful air pressure in cylinder
Cylinder can be made quickly to move, great threat is caused to neighbouring personnel and object.
The content of the invention
