130CNC-2A-1S Pipe Bending Machine

Introduction of 130 CNC-2A-1S pipe bending machine

The 130 fully automatic pipe bending machine is a three-dimensional, fully automatic, single-layer, two-axis CNC pipe bending machine. It employs a hydraulic cylinder-driven toothed sprocket bending mechanism. Clamping, material handling, material support, mold guiding, and core pulling are all driven by hydraulic cylinders. Automatic feeding is on the Y-axis, and rotation on the B-axis is driven by an electrically controlled servomotor and planetary reducer.

It features high bending power and high three-axis control precision. All program writing and input are performed directly on a conversational Windows computer touchscreen, ensuring convenient, fast, and accurate information operation.

This high-performance, large-scale, three-dimensional fully automatic CNC pipe bending machine is widely used in mass production or standardized production, such as in automotive and locomotive parts (e.g., oil pipes, gas pipes, and air conditioning parts), as well as in pressure vessels, nuclear power, aerospace, and general engineering piping.

a) It adopts a servomotor from Mitsubishi, a Delta PLC control system, and a Weintek 15-inch color touchscreen, 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-language options can be installed according to customer needs.

d) It has multiple processing programs and multiple bending programs.

e) The processing and bending programs have unlimited memory storage time and will not be lost due to power outages or long-term disuse.

f) The processing program has protection and locking functions to prevent others from modifying it at will.

g) It has a coordinate transformation function (XYZ → YBC), which is convenient for operators to use.
G1) Programming can select the mirroring function.

h) The bending program allows for setting independent machining speeds for each axis in 0–9 segments at each machining step. This allows for flexible application to different workpieces and improves work efficiency. The machining speed can also be increased or decreased at any time as needed via an external speed knob.

i) During automatic processing, it has the function of switching between “direct feed” and “clamping” to meet the processing needs of different workpieces.

j) It has processing counting and timing functions during automatic processing.

k) If an error or malfunction occurs during automatic processing, the machine can be paused. After the error or malfunction is resolved, the machine can be allowed to continue the work that was not completed for the pipe fitting, thus avoiding waste of the pipe fitting.

l) The control program has an automatic error detection and countermeasure text display function. Information about machine malfunctions or illogical operations will be directly displayed on the screen, along with explanatory instructions, to prevent human error from damaging the machine. The aforementioned automatically detected anomalies and all routine information will be recorded and automatically stored for future maintenance reference.

m) It has a mode setting function in both automatic and manual modes, and can set a variety of different working modes, such as different states such as no core insertion, auxiliary push, single step execution, etc., to improve production efficiency.

n) It has multiple delay parameter settings, which can select the appropriate time difference for each axis movement to meet various bending changes.

o) It has a button with automatic circuit input/output detection function, which can easily find possible fault locations.

p) During the processing, the current processing values of feeding Y-axis, rotation B-axis, and bending C-axis are displayed on the mobile touchscreen. It can also set single-step execution, semi-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 rotation B-axis are both driven by electric servomotors. Both axes can be selected to return to the origin. At the same time, each bend can be set with a rebound compensation value and demolding gap according to material changes.

Q1) The feeding device (Y-axis) can locate the bending position of each bend and the distance between bends.

Q2) The corner device (B-axis) can realize cornering and positioning in different directions for each bend.

r) The machine head, bending arm, and clamping mechanism are ingeniously and reasonably designed. At the same time, the bending mold is easy to replace, which facilitates flexible production and provides a large three-dimensional bending space for pipe bending.

s) The hydraulic main clamping and auxiliary clamping mechanisms use hydraulic cylinders and linkage mechanisms to drive mold clamping, and the clamping also has a self-locking function.

The pipe bending (C-axis) has both fast and slow bending functions. The slow bending function is used for bending pipes with thin walls or small bending radii, which can effectively reduce breakage caused by the pipe during fast bending.

w) The guide mold assist function can more effectively ensure the thinning rate of pipe fittings.

x) The hydraulic automatic core-pulling function can retract the core in advance and advance the core in one step, which can more effectively ensure the bending ovality of the pipe fitting.

y) Hydraulic material support mechanism: The material support mechanism can reduce the pressure on the machine tool structure when the material is clamped at one end, and at the same time can effectively ensure that long pipes are bent in a straight line and that the pipes are not easily twisted.
