What should be paid attention to in the operation of wc67k series cnc hydraulic press brake?

wc67k series cnc hydraulic press brake must be familiar to you, and then Sheng film machinery Xiaobian for you to explain in detail the operation of cnc hydraulic press brake should pay attention to what:

Based on the principle of hydraulic transmission, the implementation of components (cylinder and plunger or piston) simple structure, structure is easy to complete a large task pressure, large task space and long task stroke, mechanical manual bending machine company, thus strong compliance, easy to suppress large or long higher workpiece.

The maximum extra pressure on the press can occur at any point in the outer stroke.It can maintain pressure for a long time at the lower conversion point, which is very necessary for many processes.

The sliding block speed can be adjusted at the level of affirming the category connotation commensurate, so as to comply with the process of the different requirements of the sliding block speed.When the pump is used for indirect transmission, the speed adjustment of the slider can be related to pressure and stroke.

The total stroke of the slider can be arbitrarily changed in a certain category, and the lower conversion point of the slide stroke can be controlled or changed according to the pressure or stroke.

The operation of hydraulic bending machine should pay attention to the following points:

1. In this process, the pressure will automatically stop falling after pressurizing the weak point, and the pressure will slow down in the process of sharp rise, and can not fall or rise.

2, automatic stop when the pressure;The increase is normal, not a rapid drop, but the normal pressure of the product.

3, when high and low pressure products.Sometimes it's half normal, sometimes it's half abnormal.But when the two are normal, the two are not.The two sides of the normal, abnormal middle.

Asymmetric heating of bending machine failure

The bending machine comprises a bracket, a working table and a clamping plate, the working table is arranged on the bracket, the working table is composed of a base and a pressing plate, the base is connected with the clamping plate through a hinge, the base is composed of a shell, a coil and a cover plate, the coil is placed in the depression of the shell, the top of the depression is covered with a cover plate.When in use, the wire is energized to the coil, and after energized, the pressure plate generates gravity, so as to realize the clamping of the thin plate between the pressure plate and the base.Because of the use of electromagnetic force clamping, so that the plate can be made into a variety of workpiece requirements, and can be processed on the side wall of the workpiece.

The so-called heavy bending machine is simply a large bending machine, heavy bending machine is divided into manual bending machine, hydraulic bending machine and CNC bending machine.

Before holding the bending machine maintenance or cleaning machine, the upper die should be aligned with the lower die after the shutdown, until the end of the matter, any metal heating to expand, because the steel in the heating, unified a heavy bending machine mold parts of the temperature imbalance (i.e., heating error called).Hydraulic bending machine according to the flow essentials can be divided into: up - moving, down - moving.

This will certainly cause the non-uniformity of the expansion of each part of the mold steel, resulting in the formation of uneven internal stress due to heating.If you need to hold the boot or other use, you should choose the mode in manual and -- silent.Bending machine in the steel phase change point below the temperature, mechanical manual bending machine quotation, error called the heating emergency breeding breeds thermal stress, so the faster the heating speed, heavy bending machine mold appearance and the heart of the temperature difference is greater, the greater the stress.

Imagine, if the accuracy and Angle of the bending machine can not --, then, it is likely to lead to the whole production into the road of non-standard.The fault of the bending machine is called heating.

More than cross phase change temperature heating divergence error said, will also breed breed produce layout change of unequal time, both breeds breeds produce layout stress.The whole production process will cause a certain impact.

And bending machine mold heat treatment punishment after breeding deformation is greater, so the heavy bending machine filter is used to eliminate impurities in the medium, in order to cover the normal use of the valve and configuration.Whether the scale of the bending machine mold production lies in the specification of precision and Angle.Hydraulic bending machine according to the synchronization points can be divided into: torsional shaft synchronization, machine - hydraulic synchronization, and electric - hydraulic synchronization.

CNC bending machine is a new kind of large machine, manual bending machine, its accuracy is many people - and can adopt flexible mode of operation, as well as linkage of two, solve the problem of long plate production, and can be made of single machine processing operation, improve the utilization rate, reduce the energy consumption and compensation by CNC system automatic adjustment, convenient.

Ordinary bending machine we have seen, and CNC bending machine is a CNC operating system, through the system for bending operation.Frequent process conversion can reduce the labor intensity of operators.NC bending machine has multi - step programming function, can realize multi - automatic operation, complete multi - step parts -- processing.

CNC bending machine, also divided into point move CNC bending machine, the frequency of CNC bending machine, servo CNC bending machine, servo nc servo nc and digital servo nc is also divided into pulse, from - for, twisted axis nc belong to semi-automatic nc, from a certain extent, improve the accuracy of the bending machine, speed, and also brought some special, can greatly improve the work efficiency of function,For example, automatic avoiding, mold library, cycle single step, Angle direct calculation, precision can reach 0.05mm, at the same time the torsion axis CNC mold is higher than the ordinary bending machine requirements, machine frame processing requirements are higher, and then there is an electric hydraulic servo CNC bending machine, belongs to the automatic bending machine, can real-time synchronous control,Do not need to be like ordinary bending machine with a balance bar forced synchronization, can be sold through proportional servo valve, Guangshan ruler, monitoring, mechanical manual bending machine to achieve pressure distribution control, functional aspects, you can directly control material properties, control pressure.

The operation requirements and skills of CNC bending machine are much higher than that of hydraulic bending machine, and relatively complex.The hydraulic bending machine is electrified by the wire to the coil. After electrified, the pressure plate generates gravity, so as to realize the clamping of the thin plate between the pressure plate and the base.Because of the use of electromagnetic force clamping, so that the plate can be made into a variety of workpiece requirements, and can be processed on the side wall of the workpiece.The hydraulic bending machine comprises a bracket, a working table and a clamping plate, the working table is arranged on the bracket, the working table is composed of a base and a pressing plate, the base is connected with the clamping plate through a hinge, the base is composed of a shell, a coil and a cover plate, the coil is placed in the depression of the shell, the top of the depression is covered with a cover plate.When in use, the wire is energized to the coil, and after energized, the pressure plate generates gravity, so as to realize the clamping of the thin plate between the pressure plate and the base.Because of the use of electromagnetic force clamping, so that the plate can be made into a variety of workpiece requirements, and can be processed on the side wall of the workpiece.
