Four roller metal bending machine, 1) ISO9001-2000, 2) Easy operation, 3) Easy mantenance, 4) After service for 14 mouths - details see: https://www.machineto.com/four-roller-metal-bending-machine-hydraulic-show-window-1-10123658

W12 FOUR ROLLER METAL BENDING MACHINE

SUPERIORITY OF FOUR ROLLER SHEET BENDING MACHINE

1. Hydraulic-driven, high efficiency(driving power equivalent 60% traditional)

2. Permanent lubrication technology(bearing life period without refueling)

3.Ciamping pressure is adjustable(non-existent skidding, productivity is 50%-80% than three roller plate rolling machine)

4. Rolling diameter can catch 1.1 times of the top roller

MACHINE CHARACTERISTICS

1. CNC control system

2. Leveling easily

3. Once circle forming

4. Large cone rolling more convenient

5. Easy to correct the wrong edge

FOUR ROLLER METAL SHEET BENDING MACHINE TWO STRUC- TURAL CHARACTERISTICS

1. Arc swing of the side roller, leverage increased pressure forces

2. Proportional valves on both sides of the roll sync- Carbonization

FOLLOWING USERS APPLY TO USE THE MACHINE

1. First use of the user, because this is one of the most easy-to-operate machine

2. Operators lack of inspection requires high productivity

3. Requires high accuracy, improving quality

4. Want only one operator, reducing labor costs

5. Due to the large size of the board, production of high or for security reasons require handling device, Feeding plate form, side and upper feeding device

5. Want to use CNC operations, reduce operational personnel action levels and other factors

Technical advantage:

All working components have a safety shield and action alert;

Electrical control system has safe emergency stop devices, security lights;

Hydraulic cylinder with the refrigeration unit, make sure that hydraulic pump works at room temperature;

All the hydraulic valve, seal, not need to change in 3 years, hydraulic oil does not need to be replaced each year, reduce maintenance costs;

Only need one operator, facility CNC control, wireless remote control.

Quality Assurance Measure

We in order to achieve customer satisfaction, to ensure that customer needs and expectations are determined, as “strict management, sophisticated, high-quality service and customer satisfaction, continuous improvement, sustainable development” to the quality policy. Realization of a product from the design, control and manufacturing process control, inspection and control until the equipment leave factory, installation, service throughout the entire process of the control. Quality system strictly implement the “quality manual” “program files” “job files” and a variety of technical standards, management standards, enterprise custom standards and regulations. The product quality really realize the full-crew, full processing control.

Important Out Sourcing Quality Assurance Measure

•a. Native important outsourcing: upper roller, lower roller, support roller stock, master cylinder, bearings, hydraulic components, motor, reducer, bearings, etc;

•b. Select after evaluation of qualified suppliers as incoming channels;

•c. According to the plan, purchase contract, quality requirements, technical standards, acceptance criteria for procurement;

•d. From the company's quality control department at the supplier site, or at the supplying party scene, our company site acceptance verification before release into production.

Provide testimony of information

1.Top, bottom, and supporting roller available: chemical composition, mechanical properties, heat treatment, ultrasonic flaw detection, machining precision and hardness report;

2.Structural sheet material available: sheet material, relieve stress and processing reports;

3.Certificate of motor, bearings, seals, hydraulic pump, hydraulic valve, electric devices, etc.

Major parts of the manufacturing process

1.Working rollers: cast steel ingot (chemical composition analysis): check performance-forging roughcast—forging annealing-UT flaw—roughing (mechanical tests)-heat treatment (hardening and tempering)—UT flaw—semi finishing—finishing—MT

2.Large forgings: cylinder body, gear, gear shaft forging roughcast—surface inspection–roughing—UT flaw—UT flaw detector heat treatment—finishing semi—finishing—MT

3.Welding structure: racks, chassis, wheel box

Plate into the factory (chemical composition analysis, mechanical properties test)—pretreatment—for sheet metal cutting-welding-seam UT or RT flaw—annealing treatment—roughing-finishing—vibration destressing—hot blasting —finishing

Note: the above each process in the check for the next procedure.

After-sales service

After acceptance, in 14 mouths warranty, if the problem due to the design and manufacture, will resolve by the supplier.

In the device warranty, suppliers of equipment need to provide maintenance services on a timely basis, free of charge on non-human caused damage of all kinds of components, free replacement should be timely, the replacement warranty from the date of replacement.

The warranty period if the equipment appears the breakdown, suppliers at short notice to buyer's 24-hour response, free maintenance.

Post-warranty equipment failure, supplier upon receipt of notification from the buyer within 24 hours to respond, the maintenance charge will include the cost of spare parts,the fly tickets of our engineers and pay for USD50.00/one day/one person.

Bending machine for all parts, spare parts, attachments, ensure supply for all life of the equipment. Once spare parts stop the production must inform the buyer in advance of three months. For this matter, the supplier shall provide drawings and technical data for processing to buyer freely, in order to ensure the follow-up of the spare parts supply.
