Use and classification of corner shearing machine  . The shearing machine is mainly used in cutting the straight edge of various sizes of sheet metal and is widely used in cars, planes, steel rolling, tractors, ships, Bridges, electric appliance, instrumentation, boiler, pressure vessel and other industries.

There are many kinds of shearing machine. According to shearing machine function, shearing machine working principle and structure, they can be divided into:

First, the Flat blade shearing machine.

It features superior quality, small deformation but large energy consumption. And the two blades are parallel to each other. It is often used in the hot shearing of the Square bloom and the slab in plants.

Second, inclined blade shearing machine.

The upper and lower blade of the shearing machine form an Angle, and the upper blade inclines 1 ° ~ 6 °. The shearing force of the inclined blade shears is smaller than that of the flat blade shearing machine, so the power of the motor and the weight of the whole machine is smaller. It is commonly seen in the practical application. This kind of shearing machine is divided into guillotine shearing machine and pendulum sheet shearing machine according to the motion of the tool holder. And according to the main drive system, it can be divided into two types: mechanical transmission and hydraulic transmission shearing machine.

Third, Multi-purpose shearing machine:

The sheet bending and shearing machine can complete the cutting and bending process on the same machine, which is convenient and practical. Combined punching and shearing machine can be used for cutting of sheets and proximate matter, most of which occur in the laying-off process.

Forth, Special shearing machine:

Sheet flat line shearing machine is used in sheet coil straightening lines. The high-speed shearing machine is designed to cooperate with fast shear requirements. On the thick sheet shearing line, there is mostly hydraulic high-speed shearing machine. While on the thin sheet line, there is mostly pneumatic guillotine shearing machine. And on the high-speed line, there is flying shear, which can work continuously and brings high production efficiency. Steel structure production line shears are mostly used in Angle steel and H section automatic production line to complete the cutting process. Cold bending molding line shears, such as the cold bending line of automobile longitudinal beam, the production line of the side baffle of the car, the molding line of color steel sheet and other special shearing machines.

How does a balancing valve work?
Balancing valve is a special function valve. It has good flow characteristics. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal. As long as the balance valve with appropriate specifications is installed in each branch and user's entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value.
Static balancing valves are also called balancing valves, manual balancing valves, digital locking balancing valves, double-position regulating valves, etc. It is through changing the clearance between the spool and the seat (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating flow. Its object of action is the resistance of the system, which can distribute the new water in proportion to the design calculation, increase and decrease the branches in proportion at the same time, still meet the flow demand of part of the load under the current climate needs, and play the role of heat balance. Dynamic balancing valves are divided into dynamic flow balancing valves, dynamic differential pressure balancing valves, self-operated differential pressure control valves and so on.
Dynamic flow balance valve is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes the drag coefficient according to the change of system working condition (differential pressure). In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. On the contrary, when the pressure difference decreases, the valve opens automatically and the flow rate remains constant. However, when the pressure difference is smaller or larger than the normal working range of the valve, it can not provide additional pressure head after all. At this time, the flow rate of the valve to the full open or closed position is still lower or higher than the set flow rate can not be controlled.
Dynamic differential pressure balancing valve, also known as self-operated differential pressure control valve, differential pressure controller, constant voltage variable synchronizer, differential pressure balancing valve, etc. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. The valve working principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system, that is, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases by automatically closing the valve. When the pressure difference decreases, the valve opens automatically, and the pressure difference remains constant. The self-operated pressure difference control valve has an automatic plug closing state within the control range. The pressure difference between the two ends of the valve exceeds the preset value. The plug opens automatically and adjusts the opening automatically under the action of the pressure sensitive film to keep the pressure difference between the two ends of the valve relatively constant.

The mechanical press machine working design principle of the mechanical power press is to convert the circular motion into a linear motion, and the main motor outputs the force to drive the flywheel. The clutch drives the gear, the crankshaft (or the eccentric gear), the connecting rod, etc. to achieve the linear motion of the slider. The motion of the motor to the connecting rod is a circular motion. There is a need for a circular motion and a linear motion transfer point between the connecting rod and the slider. The design has roughly two mechanisms, one is a spherical type and the other is a pin type (cylindrical type), and the circular motion is performed via this mechanism to a linear motion of the slider. The presses release the force on the material to plastically deform it to obtain the required shape and precision. Therefore, it is necessary to match a set of molds (dividing the upper mold and the lower mold), placing the material between them, and applying pressure by the machine to make it deformed, the reaction force caused by the force applied to the material during processing is absorbed by the mechanical body of the press.

The power source of electric forklift truck is mainly battery and DC motor. The correct use of battery for forklift truck includes correct charging operation and correct replacement. Those two correct uses and other operation problems are the basic skills to keep the parts of electric forklift truck in the optimal state.

First of all, the charging operation of forklift truck batteries. Forklift truck batteries are a relatively fragile aspect. If the maintenance work is done well in this respect, it will prolong the use time and life of electric forklift truck batteries. On the contrary, it will reduce work efficiency and speed up the loss of batteries, and ultimately the batteries can not work properly.

1.Forklift drivers should pay attention to the battery power displayed on the forklift display board before starting or charging each time. The best way to recharge the battery is to recharge the battery when there is still 20% of the power, instead of using up all the power.

2.Before charging the forklift battery, it is necessary to confirm the matching of the forklift charger. Charging machines which is not matched will seriously affects the service life of the battery, or directly damages the battery.

3.Charging should be done in a well-ventilated place, opening the top cover or removing the battery from the forklift truck. The best way to charge a battery is to open the lid and let it be ventilated.

4.Connection plug of charger must be in place.

5.In the charging of forklift truck battery, if the battery needs to be used before it is full, the suspension switch must be turned off first. Otherwise the electricity will return, so that it will be easy to burn the charger computer board.

6.Battery surface or connection must be clean and dry.

7. Do not place tools or other metal objects on batteries.
