Precision punching machine equipment structure

   Precision punching equipment overload oil pump has a protection of moulds, emergency stops in critical situations, jamming the mould when the disengagement, reduce the connection gap, sense the eccentric load and so on five major functions. To use a good precision high-speed punch press, understand the working principle of the overload oil pump is essential, my company machinery in its do a detailed description:

     The actual use of precision high-speed punch press, overload oil pump on the pressure switch on (ON), so that the company's precision high-speed punch press is in operation. Indicates overload protection, square tube CNC punch press machine, can be punched. After the pump starts, the main valve of the overload oil pump moves slightly to the right direction due to the initial pressure.

    When the oil pressure in the cylinder of the high-speed precision punch press rises above the set pressure, the main valve overcomes the spring force and moves to the right direction, pushing open the main valve seal to return the high-pressure oil to the tank.
Shelves can be divided into general-purpose shelves and special-purpose shelves according to the applicability of shelves.
According to the manufacturing material of shelves steel shelves, reinforced concrete shelves, steel and reinforced concrete mixed shelves, wooden shelves, steel and wooden shelves.
According to the degree of closure of the shelves are divided into open shelves, semi-closed shelves, closed shelves and so on.

   According to the structural characteristics of the shelf, layer frame, cabinet shelf, drawer shelf, cantilever shelf, tripod, grid-type rack.
   According to the mobility of shelves, fixed shelves, mobile shelves, rotating shelves, combined shelves, adjustable shelves, mobile storage shelves.
   According to the use of shelves shelves, convenience store shelves and so on.
   According to the structure of the shelves, the whole structure, shelves directly support the warehouse roof and perimeter shed, split structure, shelves and buildings are divided into two independent systems.
