DW38CNC-3A-2S fully automatic pipe bending machine is servo and hydraulic driven. The electrical appliances centrally control the bending angle, feeding accuracy, pipe rotation accuracy, left and right mold change of the bending machine head, hydraulic control clamping, guiding, up and down mold change of the machine head, mandrel, mechanism, etc. have their own independent oil cylinders. When the bending arm bends the pipe, under the control of the hydraulic system, the clamping, guiding, mandrel, and bending parts coordinate and cooperate to complete high-quality bending. It is an economical and practical general equipment. The equipment can bend metal pipes with or without cores. The machine has a single-action function, which is easy to use and maintain. It is widely used in shipbuilding, boilers, chemicals, automobile manufacturing and other industries.
a) It adopts Japan Mitsubishi’s servo motor, Delta PLC control system and Weilun 10-inch color touch screen, which has strong anti-interference ability and is suitable for use in various harsh working environments.
b) It adopts a human-computer dialogue program, which is professional and easy to use, allowing users to become familiar with the system operation in a very short time.
c) Standard Chinese display, Chinese and English dual languages can be installed according to customer needs.
d) It has multiple sets of processing programs and multiple sets of bending programs.
e) The processing program and bending program memory storage time is unlimited, and the program will not be lost due to power outages or long-term non-use.
f) The processing program is equipped with protection and locking functions to prevent others from modifying it at will.
g) It has a coordinate conversion function (XYZ->YBC), which is convenient for operators to use.
G1) The program can choose the mirror function.
h) The bending program can set the independent processing speed of each axis in each processing step 0-9 segments. It can be used flexibly for different workpieces to improve work efficiency. The processing speed can be reduced or increased at any time as needed through the external speed knob.
i) During automatic processing, it has the “direct feed” and “clamp and place” feeding function switching to meet the processing needs of different workpieces.
j) During automatic processing, it has processing counting and timing functions.
k) If an error or fault occurs during automatic processing, the mechanical action can be suspended. After the error or fault is eliminated, the machine can still be selected to continue to complete the unfinished work of the pipe fitting, so as to appropriately avoid the waste of pipe fittings.
l) The control program has the function of automatically detecting errors and displaying countermeasures in text. Information about machine failures or illogical operations will be directly displayed on the screen, with instructions to prevent human operation errors from damaging the machine. The above-mentioned abnormal information detected automatically will be recorded and automatically stored for future maintenance reference.
m) It has a mode setting function in both automatic and manual mode, and can set a variety of different working modes, such as core penetration, auxiliary push, single-step execution and other different states to improve production efficiency.
n) It has multiple delay parameter setting values, and can select the most appropriate time difference for each axis action to meet various bending changes.
o) It has a button circuit input and output automatic detection function, which can easily find the possible fault location.
p) During the processing, the mobile touch screen displays the current processing values of the feeding Y (axis), corner B (axis), and bending pipe C (axis). It can also set single-step execution, half-cycle operation, and full-cycle operation. At the same time, it can freely select manual, semi-automatic, fully automatic, and slow bending functions. It adopts elastic button switches and has three functions: automatic start, emergency stop, and emergency stop to continue working. It is convenient for manual intervention when bending special workpieces and has high safety performance.
q) The feeding Y (axis) and corner B (axis) are both driven by electric servo motors. The two axes can choose the return to origin function. At the same time, each bend can set the rebound compensation value and demolding gap according to the change of material.
Q1) The feeding device (Y) axis can realize the bending position of each bend and the distance between the bends.
Q2) The corner device (B) axis can realize the corner and positioning of each bend in different directions.
r) The design of the machine head, bending arm, and clamping mechanism is exquisite and reasonable. At the same time, the bending mold is simple and convenient to replace, which is convenient for flexible production and provides the largest three-dimensional bending space for pipe bending.
s) The hydraulic main clamping and auxiliary clamping mechanism uses a cylinder and a connecting rod mechanism to push the mold to clamp, and the clamping also has a self-locking function.
t) The bending (C) axis has fast bending and slow bending functions. The slow bending function is used for bending pipes with thin wall thickness or small bending radius, which can effectively reduce the breakage caused by the fast bending process of the pipe.
w) The auxiliary push function of the guide mold can more effectively ensure the thinning rate of the pipe.
x) The hydraulic automatic core pulling function can withdraw the core in advance and advance the core in a single step, which can more effectively ensure the bending ovality of the pipe.
y) Hydraulic support mechanism: The support mechanism can reduce the pressure on the machine tool structure when the material is clamped by a single head, and can effectively ensure the straight bending of long pipes, and the pipes are not easy to twist.
