Contrast of CNC bending machine and hydraulic bending machine

Introduction to the working mode of hydraulic bending machine

In the process of hydraulic bending machine bending, Suqian manual bending machine, the pressure between the upper die and the lower die is not, by adjusting the die of the concave die - open access to the required bending Angle, this bending way is called bending gap.Deep into the lower die mold, the bending Angle of the bending machine is smaller, the larger the bending Angle is, and vice versa.Because of the elastic material, there is also a need to consider when bending to control the amount of springback with over-bending, the advantage of bending clearance is that you can use a smaller number of molds, achieve multiple forming angles, require less handling and less pressure.In general, in order to achieve the best bending effect, the material thickness T and V lower die V type opening width ratio according to T: 1:8V: Today, the film Xiaobian to introduce the working method of hydraulic bending machine to you:

(1) Set pressure holding time, pressure relief time, horizontal stopper advance and retreat distance, adjust the position of horizontal stopper.

(2) Set the number of working steps, the blocking position of each working step and the number of bending sheets.

(3) select the continuous operation gear, the lower bending mechanism is not in the upper travel switch position, the first automatic return to the upper travel switch position;Step down the foot slowly into, down the bending mechanism automatically down pressure;When the travel switch is touched, the horizontal retaining mechanism sets the distance back, and the pressure is kept automatically.Pressure holding time to automatic pressure relief, pressure relief time to press down the bending mechanism automatic return, while the horizontal retaining mechanism automatic forward setting distance;Hit the travel switch, a bending action over, for the next bending.

(4) When the bending times of the current working step are completed, the horizontal retaining position will be automatically adjusted when the travel switch is touched, and the bending action of the next working step will be entered.

(5) all the work step action is completed, hit the travel switch, electric manual bending machine company, continuous bending action is over.This article is reprinted from laser cutting machine

Contrast of CNC bending machine and hydraulic bending machine

The bending machine can be divided into CNC bending machine, hydraulic bending machine and manual bending machine.Today, the performance of the filling film is simple and you compare what are the differences between CNC bending machine and hydraulic bending machine:

Numerical control bending machine and hydraulic bending machine, is characterized by its numerical control operating system, which is the ordinary bending machine and reduce the operator's labor force and can enhance processing efficiency.But at the same time, the operation requirements and skills of the CNC bending machine are much higher than the hydraulic bending machine, and relatively complex.Numerical control bending machine has multi-step programming function, can realize multi-automatic operation, mechanical manual bending machine, complete multi-step 0 pieces 1 processing.

manual clamp

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 the wire is energized by the coil, the mechanical manual bending machine will generate gravity on the pressing plate after energizing, so as to realize the clamping of the thin plate between the pressing 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.

Hydraulic bending machine must be familiar to you, and then Sheng film machinery Xiaobian for you to explain in detail the operation of hydraulic bending machine should pay attention to what:

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

back gauge

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.

40T

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.
