4 Roller CNC Hydraulic Plate Rolling Machine, Roller Bending Machine

Product Description

Product Description
W12NC 4-roller plate rolling machine/plate bending machine Introduce: The machine adopts the four-roller structure with the upper roller as the main drive. The equipment has the function of pre-bending the end of the plate. The metal sheet can be loaded at one time, and the plate end pre-bending and the roll forming of the workpiece can be completed without turning. The upper working roller of this machine is the main driving roller. The lower roller and both sides of the roller adopt hydraulic transmission. The lifting displacement is controlled by the computer, automatic leveling, screen display, and the tilting and resetting of the turning bearing body to adopt hydraulic transmission. The tail of the upper roller Equipped with a balance mechanism to facilitate the unloading of the rolled workpiece and cylinder. Equipped with a mobile independent operating table, which can be moved and operated at any time, and the machine is equipped with a safety interlock device. The machine has a high technical level, complete functions, high precision, and easy operation. It is the most ideal model for rolling round, arc, and conical workpieces in industries such as energy, transportation, petroleum, chemical industry, boilers, shipbuilding, hydropower, and metal structures.

Working principle:
Quality assurance measure
Quality assurance system
Company 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" or "program files" and "job files" and a variety of technical standards, management standards, enterprise custom standards and regulations. The product quality really full, the entire process control.
Quality testing
Company laboratory analysis of chemical elements with conventional equipment, WE-300 hydraulic universal testing machine, ultrasonic flaw detector, XCTY-12 CT-1000 magnetic particle testing machine, automatic microprocessor-based carbon HV-4B Analyzer, HB-2H high-speed automatic ignition oven, WS2-226-77-heating Distiller, 722 Visible Spectrophotometers, TG-3288 analytical balance, as well as a variety of specialized measuring tools, universal measuring and large gauge, etc.
Important outsourcing quality assurance program
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, such as 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, chasis, 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-finishing
Note: the above each process in the check for the next procedure.
