Detailed analysis and detailed explanation of the structure of automatic pipe bending machine

Detailed analysis and detailed explanation of the structure of automatic pipe bending machine

The difference and difficulty between this system and traditional single head hydraulic pipe bending machine is that the system can meet the needs of different condensers with bending radius R50, R60 and R70 respectively. Second, when all the bending parts at one end are formed automatically, the bending parts at the other end can be bent automatically by turning the head, and the condenser products with both ends bent can be removed from the bending roll. The main purpose of U-turn is to reduce the radius of curvature that has been bent with bending action. Three, we can bend different angles according to the different requirements of each bending part.

The main purpose of U-turn is to reduce the radius of curvature that has been bent with bending action. Three, we can bend different angles according to the different requirements of each bending part.


By adjusting the center distance between roller 1 and roller 2 and replacing the roller connecting plate, it is possible to meet the needs of different condensers with bending radius of RS0, R60 and R70 respectively. The open roller is also allowed to turn and bend, and the condenser product at both ends is bent out of the bending roll. In order to bend different angles according to the different requirements of each bending part, we adopt the combined limit mechanism which has been successfully developed in the process of long-distance positioning, and meet the requirements of bending different angles according to the different bending parts.


In order to improve the reliability of the system, we adopt a closed-loop control method with a terminal position sensor for all actions. Compressed air is used in all power parts and the cylinder is used as the action actuator. The double electric control reversing valve controls the movement of the cylinder, so that each action has a memory function. The main control part adopts high-performance programmable logic controller. In the design of control program and control circuit, all kinds of complex situations in the process of equipment adjustment and operation are fully considered. Whenever power failure or gas failure occurs, the program state is remembered by the holding counter and the holding status register. When the program is called and the gas supply is restored, the operation can be resumed. Caller instantaneous dual-electronic control reversing valve maintains the state of gas path before power cut and gas cut, and starts the next state transition condition until the corresponding action reaches the end of stroke and the position sensor has signal, then carries on the corresponding follow-up action, so as to avoid waste products due to power cut and gas cut. In order to meet the needs of different products, corresponding control programs are designed for different types of main condenser parts. When replacing condenser parts, the corresponding control program can only be switched by using a selector switch.

Three criteria for correctly selecting solenoid valves of China single head hydraulic automatic pipe bender

Three criteria for correctly selecting solenoid valves of China single head hydraulic automatic pipe bender

Selection of solenoid valves for pipe bender 1. The fluid in the applicability pipeline must be consistent with the medium calibrated in the series of solenoid valves selected.

Selection of solenoid valves for pipe bender
1. The fluid in the applicability pipeline must be consistent with the medium calibrated in the series of solenoid valves selected. The temperature of the fluid must be smaller than the calibration temperature of the solenoid valve. Solenoid valve allows liquid viscosity generally below 20CST, greater than 20CST should be noted. When the working pressure difference is less than 0.04 MPa, the direct-acting and step-by-step direct-acting type such as ZS, W, ZQDF, ZCM series should be selected; when the minimum working pressure difference is greater than 0.04 MPa, the pilot (differential pressure) solenoid valve can be selected; the maximum working pressure difference should be less than the maximum demarcation pressure of solenoid valve; generally solenoid valves are unidirectional, because of This should pay attention to whether there is a reverse pressure difference, if there is a check valve installed. When the fluid cleanliness is not high, the filter should be installed in front of the solenoid valve. Generally, the solenoid valve requires a good cleanliness of the medium. Pay attention to the flow aperture and nozzle aperture; solenoid valve is generally only controlled by two switches; conditions permit the installation of bypass pipe for easy maintenance; water hammer phenomenon to customize the opening and closing time of solenoid valve adjustment. Attention should be paid to the influence of ambient temperature on the solenoid valve power supply current and power consumption should be selected according to the output capacity, power supply voltage is generally allowed to be around + 10%, it must be noted that AC starting VAs higher.
2. Reliable pipe bender solenoid valve is divided into normally closed and normally open two kinds; generally choose normally closed type, power on, power off and close; but in a very short time to choose normally open type when the opening time is very long. Life test, factories generally belong to type test items, to be exact, there is no professional standards for solenoid valves in China, so choose solenoid valve manufacturers carefully. Action time is very short, when frequency is high, generally choose direct acting type, large diameter selects fast series.
3. The safety of the general solenoid valve is not waterproof, when conditions do not permit, please choose waterproof type, factory can be customized. The maximum nominal pressure of solenoid valve must exceed the maximum pressure in the pipeline, otherwise the service life will be shortened or other accidents will occur. All stainless steel type should be used for corrosive liquids, and plastic king (SLF) solenoid valve should be used for strong corrosive liquids. Explosion-proof products must be selected for explosive environment. 4. Economy has a lot of solenoid valves can be used in general, but on the basis of meeting the above three points should choose the most economical products.

How is the accuracy of cnc pipe bending machine bending the aircraft tubing?

How is the accuracy of cnc pipe bending machine bending the aircraft tubing?

A few years ago, the accuracy of the cnc pipe bending machine was not the main contradiction. Because the process of bending is not so much science, it is better than art. Machine repeat ability is more important. When the setting is satisfactory, the bending machine only needs to repeat the bend. Nowadays, the materials are expensive and the batch size is small. Aircraft manufacturers must look for machines that can be accepted for the first time. Therefore, the first step in producing a good product is to have a sophisticated machine.

A few years ago, the accuracy of the cnc pipe bending machine was not the main contradiction. Because the process of bending is not so much science, it is better than art. Machine repeat ability is more important. When the setting is satisfactory, the bending machine only needs to repeat the bend. Nowadays, the materials are expensive and the batch size is small. Aircraft manufacturers must look for machines that can be accepted for the first time. Therefore, the first step in producing a good product is to have a sophisticated machine.

The benefits of some precision cnc pipe bending machine are obvious. If the tube is produced for the first time, the productivity will increase and the defective rate will drop. Some of the benefits are not obvious: if a factory has several bending machines, as long as the machines are sophisticated, the bend data of the good work pieces can be shared. This is an important difference between accuracy and repeat ability. A single machine can be repetitive, producing the same product at the same time with the same data; but a group of machines must be sophisticated in order to produce the same product on the same data on any of the machines.

Rotary pull elbows are commonly used in the aircraft industry, where the tubes are formed along a rotating bending die. The production process is relatively simple: pipe positioning, bending, pipe to the next bend position. The accuracy of the bending machine can be divided into three curved tube forming axes: the bending length (DBB), the bending plane (POB), and the bending angle (DOB).

A typical aircraft conduit linear requirement is +/- .010 inches. However, due to the long length of the conduit, it is more realistic to specify the basic accuracy and then accumulate tolerances per foot. The accuracy of modern CNC cnc pipe bending machines is +/- .004 inches, plus an accumulated tolerance of +/- .001 inches per foot. Repeatability is +/- .004 inches for the entire length.

The accuracy of the two rotating axes of the aircraft quality cnc pipe bending machine is +/- 0.01 degrees and the repeatability is +/- 0.05 degrees.

There are several designs on the CNC bending machine to ensure these high precision. On the C-axis, the feedback element (usually a high-resolution encoder) is mounted directly on the elbow arm to directly read the position. On small cnc pipe bending machines, if the encoder is likely to interfere with the pipe, it can be operated by parallel links. The bearings at the joints must have very small tolerances to reduce migration and maintain accuracy.

The B-axis of the bending machine is usually driven by several stages of speed reduction mechanisms. The feedback encoder is mounted on the last stage drive shaft to optimize accuracy and repeatability.

The Y-axis of the bending machine has special problems. Aircraft ducts are much longer than other industries. The most efficient positioning methods are gears and racks. To achieve an accuracy of +/- .001 inches per foot, precision ground racks, high quality gears and direct drive feedback must be used.

Another design requirement for a precision bending machine is that the servo system of the positioning shaft must be "hard". The movement of the mechanical components must be minimal and the electronic servo loop must be positioned and maintained within the required tolerances.

There are other factors that affect the accuracy of the workpiece when using a very precise bending machine. These process variables include various material properties and dimensional tolerances, tooling and tooling settings, lubrication, and weld location.
