Find the right tube bender for metal tube processing

Metal sheet and pipe processing is one of the most important links in the manufacturing industry. Faced with the large-scale sheet metal processing needs from industries such as new energy vehicles, energy storage, and communication cabinets, it is very important to find a suitable pipe bending machine. Faced with the different needs of each sheet metal factory, often only customized solutions can solve their transformation pain points.

Find a suitable bending machine

In application fields such as chassis cabinets and elevator manufacturing, the accuracy and efficiency of bending are extremely high. For example, when changing the mold, it is necessary to clamp the mold quickly and accurately to improve production efficiency. At the same time, the bending equipment itself must be equipped with automatic mechanical compensation and guide rail devices to ensure high-quality bending accuracy.
The CNC bending machine built by ANTISHICNC has higher transmission accuracy than traditional hydraulic bending machines, so it can effectively control the bending angle error and meet the needs of high-precision processing. At the same time, it is equipped with a precise and stable back gauge system and a precise quick clamping device to ensure positioning accuracy and convenient and fast mold change, and improve production efficiency.
In addition to the requirements of high efficiency and high precision, the sheet metal bending industry is still facing the current situation of large changes in product batch demand and frequent order customization. To reduce costs and increase efficiency, ANTISHICNC bending centers are also needed to meet the needs of small batches of multiple varieties. It is used to help sheet metal companies solve the problem of reducing labor costs and fully meet the needs of increasing production capacity.

Find a suitable pipe bending machine

For the pipe bending processing of automobile and motorcycle industry pipe fittings and medical equipment pipe fittings, the bending angle and position have high-precision processing requirements. In such a market background, the fully automatic pipe bending machine has begun to shine in the pipe processing of high-end manufacturing fields such as automobiles, medical equipment, aerospace, etc. with its advantages of high precision, energy saving and environmental protection, and high degree of automation.
ANTISHICNC’s CNC pipe bending machine is mainly used for bending and forming tasks such as round tubes, square tubes, hollow tubes, solid tubes, and special-shaped tubes. It adopts a full gear clamping transmission system, and the clamping position can be adjusted by the program to accurately control the clamping position. After changing the mold, there is no need to adjust the mold, and the corresponding program can be directly called, saving time and effort.

Structural features of the fully automatic pipe bending machine:

1. Material rack: automatic material discharge

2. Straightening device: The straightening wheels are arranged crosswise on the horizontal and vertical planes to round and straighten the copper tube from two planes. Each copper tube has 2 round wheels and 12 straightening wheels, of which 1 round wheel and 4 straightening wheels are adjusted through the eccentric shaft to ensure the straightness of the large U tube.

3. Feeding device: Friction feeding is adopted, and its structural form is cylinder pressing synchronous belt feeding. Each group of synchronous belts has an independent cylinder. When feeding, the cylinder presses the synchronous belt. The upper and lower synchronous belts clamp a copper tube for friction feeding. When the feeding is almost in place, the feeding speed changes from fast to slow. The pressing cylinder on the synchronous belt changes from high pressure to low pressure, and the cylinder pressing the group loses pressure to avoid friction bending of the copper tube. The hydraulic oil motor drives the feeding, and the high and low speed hydraulic valves easily realize the working rhythm of feeding from slow speed (starting) → fast → slow speed (in place) to ensure high efficiency and workpiece quality.

4. The induction switch is used to detect the feeding in place.

5. Copper tube cutting device: The copper tube is cut by an external roller. Oil mist is sprayed during cutting for lubrication. The cutting depth of each copper tube is adjusted by the swing shaft to ensure that the copper tube cutting is synchronized and the shrinkage is less. After the cutting is completed, the feeding synchronous belt is reversed to separate the copper tube.

6. Bending device: It consists of bending clamping, bending rotation, bending die lifting and lowering. The bending rotation device is driven by the swing cylinder to rotate the bending device. The bending die is installed on a fixed plate driven by the cylinder. When the die is lowered, it can feed or unload. When the template rises, the bending die is assisted to complete the bending.

7. Unloading, core pulling, and mandrel device: The above devices are all installed on rolling guide rails. After the copper tube is bent, the active mandrel is driven by the cylinder in the clamping state of the bending die, withdraws from the bending tangent point, and then clamps and releases the material. The servo motor drives the unloading seat forward quickly through the ball screw to unload the large U tube. Connected to the movable mandrel is a connecting rod made of thick-walled cold-drawn seamless pipe. The machine is equipped with an oil mist lubricator and a distributor. The oil mist is sprayed on the inner wall of the copper pipe after the mold clamps it and bends it through the small holes on the connecting rod through the distributor to ensure the quality of the bent pipe.

8. Pipe length adjustment device: When the pipe length specification changes, it should be adjusted through the length adjustment device. The length adjustment device has the following parts:

① Bending length adjustment: used to adjust the length of the workpiece after bending. The unloading seat positioning is driven by the servo motor through the synchronous belt; the bending machine positioning is driven by the reducer to drive the lead screw nut, and the rotary encoder feedback is provided. After it is in place, it is fixed to the base by the automatic clamping device.

② Guide rack and feeder adjustment device: According to the different lengths of the pipe, the equipment is equipped with guide racks of different lengths. The feeder is driven by a cylinder, and the feeder arm is installed on a long axis. The feeder arm can slide along the long axis. Changing the distance between the feeder arms or increasing the number of feeder arms can meet the feeder requirements of workpieces of different lengths.

9. Hydraulic station
Arranged in the frame-type cutting machine frame, using variable pump with air cooler.
