Products Description

 

The hydraulic mandrel pipe bender is an advanced machine tool designed for the precise bending of metal pipes. It consists of key components such as a hydraulic drive system, servo motor control system, mandrel support device, and high-precision mold. The equipment provides stable support for the inside of the pipe during the bending process through the mandrel, effectively preventing the deformation of the pipe. It is widely used in automobile manufacturing, industrial vehicle production, metal processing, construction, fitness equipment manufacturing, boiler manufacturing, shipbuilding, heavy transport vehicle manufacturing, chemical industry, power plants, diesel engines, CNC pipe bending machines, and other fields.

Feature

 

High-precision bending
The servo motor control system of the hydraulic mandrel pipe bender can accurately control the bending angle and speed to ensure that each bend meets the preset parameters. The mandrel support device provides uniform and stable support for the pipe during the bending process, effectively preventing the deformation and wrinkling of the pipe, thereby ensuring bending accuracy. The hydraulic mandrel pipe bender can accurately control the bending angle and speed to ensure that each bend meets the preset parameters. The mandrel support device provides uniform and stable support for the pipe during the bending process, effectively preventing the deformation and wrinkling of the pipe, thereby ensuring the bending accuracy, and the bending accuracy can reach ±0.1°.

 

High-efficiency processing
The hydraulic drive system provides strong power support, allowing the hydraulic mandrel pipe bender to respond quickly to operating instructions and achieve high-speed bending. The multi-axis control system achieves precise bending of complex three-dimensional pipes through the coordinated movement of components such as the Y-axis slide, B-axis chuck, and C-axis bending arm, further improving processing efficiency.

 

Intelligent operation
The hydraulic mandrel pipe bender is equipped with an industrial PC control system, using the Windows system, and has powerful data processing and computing capabilities. The system supports intelligent functions such as 3D preview, remote control, and 3D bending simulation collision prevention. Combined with touchscreen display technology, the operation interface is intuitive and convenient, effectively reducing the difficulty of operation and the rate of misoperation.

 

The high degree of automation
The hydraulic Mandrel Pipe Bender is highly automated thanks to the synergy of the automatic lubrication system, tool shifting function, and vertical base design. The automatic lubrication system regularly provides lubrication for equipment components to reduce wear and failure rate; the tool shifting function uses hydraulic or servo motors to achieve flexible movement of tools and improve the degree of processing automation; the vertical base design facilitates emergency stop, two-hand start, and remote control, improving operational safety and convenience.

FAQ

Q: How about the delivery time?

A: Usually, it takes 30 working days for production.

Q: Do you provide all the operations and maintenance manuals in English?

A: Rich in overseas transaction experience, we have a full set of documentation, user manuals, and assembly guidance, all in English. You do not need to have any concerns about language issues.

Q: Do you offer any after-sales services?

A: After finalizing the product, we clear up the production line and send you photos and videos for your assurance. Upon request, our experienced technicians and engineers can provide installation and training services. Our customer service team is also always available to answer any inquiries if needed.

Q: What's your payment term?

A: T/T or L/C, 30% as deposit, the balance needs to be paid before delivery, but after inspection.

Q: Can your pipe-bending machines be customized?

A: Yes, we can use your control systems and print your logo on the machine; OEM is accepted for Hippo.

Q: What is the purpose of the mandrel in a Hydraulic Pipe Bender?

A: The mandrel serves as an internal support inside the pipe during the bending process. It helps prevent the pipe from collapsing or wrinkling, especially in tight radius bends. The mandrel maintains the pipe's internal structure, ensuring the material retains its shape and integrity throughout the bending process.

Q: Can a Hydraulic Mandrel Pipe Bender bend pipes at multiple angles simultaneously?

A: While most Hydraulic Mandrel Pipe Benders are designed to bend pipes at one angle at a time, some advanced models equipped with multi-axis controls can perform bends at different angles in a single operation. However, for multiple bends in different directions, the machine would need to be reprogrammed or repositioned for each bend.

Q: Is a Hydraulic Mandrel Pipe Bender suitable for mass production?

A: Yes, Hydraulic Mandrel Pipe Benders are highly suitable for mass production, especially when precision and consistency are required across large quantities of tubes or pipes. With automated controls and the ability to set parameters for repeated use, these machines are ideal for continuous, high-volume production runs.

Q: Can a Hydraulic Mandrel Pipe Bender bend pipes of different materials?

A: Yes, these machines are versatile and can handle a variety of materials, including stainless steel, aluminum, copper, carbon steel, and alloys. The hydraulic system can be adjusted to accommodate different pipe materials by modifying the bending pressure, ensuring precise results without damaging the material.

Q: What type of pipes can be problematic for a Hydraulic Mandrel Pipe Bender?

A: Pipes with very thin walls or those made from brittle materials can be more challenging for a Hydraulic Mandrel Pipe Bender, as they are more likely to deform or crack during the bending process. Some machines may require special tooling or settings to handle these materials without causing damage. Pipes with an extremely large diameter may also require larger machines with higher hydraulic capacity.
