In the fields of steel structure, profile processing and hardware manufacturing, roll forming technology is recognized by the industry as the core technology of cost reduction, efficiency increase and stable mass production. Many new friends and those in charge of procurement and production of enterprises often have two questions: what exactly is cold roll forming technology? There are all kinds of roll forming machine on the market. How should we choose? Next, I will explain these two questions for you. After reading it, you can understand and choose equipment without stepping on a mine!
I. What is cold roll forming technology?
Many people understand “roll forming” as a simple bending, but in fact it is not accurate. Cold roll forming, the full name of cold rolling continuous forming, is an advanced processing technology that relies on multiple sets of precision rollers to gradually crush and bend at normal temperature to continuously deform the metal strip and finally form a fixed cross-section profile. Simply put: no need for heating, no need for segmented stamping, a line from beginning to end, directly out the finished profile.
Compared with the traditional hot bending, bending and stamping processes, the advantages of cold roll forming are very obvious, which is also the mainstream upgrading direction of profile processing enterprises now:
1. Processing at room temperature, more energy-saving and material-saving
There is no need for high-temperature heating, which greatly reduces the cost of energy consumption; the utilization rate of continuous roller forming materials is extremely high, and there is almost no waste. Long-term production capacity helps enterprises save considerable raw material costs.
2. The size is accurate and the finished product is consistent.
Relying on precision roller form shaping to avoid the error problems of manual bending and single stamping. The flatness, straightness and cross-sectional size of the same batch of products are unified, without distortion or deformation, which fully meets the requirements of engineering support and precision processing.
3. Continuous production, the efficiency far exceeds that of traditional technology
Assembly line-type uninterrupted operation can operate stably for a long time, and the production capacity is much higher than that of segmented processing, which is very suitable for large-scale and standardized profile production.
4. The material performance is stable and the appearance is better.
Normal temperature processing will not destroy the original mechanical properties of the metal, and the strength and toughness of the profile are more stable; there are no traces of high-temperature oxidation and black burning on the surface, and the finish is high. Many products do not need secondary polishing and repair.
At present, it is widely used in: steel structure profiles, colored steel roof tiles, photovoltaic brackets, door and window profiles, storage shelves, auto parts, rail transit accessories, pipeline guards, special-shaped hardware profiles and other industries.
II. How to choose roll forming machine?
Many customers buy equipment only by looking at the price. In the end, they appear: unstable size, surface scratches, frequent deviations, unable to increase the production capacity, and continuous failures, which delay production and increase costs. Combined with many years of on-site landing experience, we have summarized 6 core selection dimensions, covering the selection needs of more than 90% of processing factories.
1.First determine the demand, and then choose the equipment
The first step of machine selection is to sort out your own production parameters and accurately match the roll forming machine:
· Processing materials: galvanized sheet, color coated steel, stainless steel, aluminum alloy, etc., the material hardness is different, and the equipment roller configuration, power and forming pressure are completely different;
·Type and Material: ordinary C/U/Z steel, square tube, round tube, or all kinds of special-section profiles, special-shaped products require multiple secondary forming rollers and customized processes;
·Plate thickness and width: the roll forming machine has standard processing intervals, forced production beyond the scope, which is very prone to deformation, running deviation and load overload;
·Production demand: small batch , multi-category selection of standard economic equipment; large-scale, single-category priority is given to high-speed fully automatic production lines.
2.Focus on the core accessories to determine the accuracy and service life.
Whether the roll forming machine is durable or not depends on the shell, but on the core configuration.
Roller: the top priority. The high-quality roll forming machine is made of high-strength alloy material and the whole quenching treatment. It has high hardness and strong wear resistance. Long-term mass production is not easy to wear and does not damage the plate, ensuring long-term size stability.
Transmission and mainframe structure: The solid transmission structure runs smoothly, the power output is uniform, and the molding process is not stuck or shaken, which effectively avoids the deviation of the plate and the uneven length.
Control system: standard equipped with a mature PLC numerical control system, adjustable parameters, simple operation, accurate and controllable ruler, punching, cutting, and ordinary workers can operate with simple training.
3.Adapt to your own production capacity mode and choose as needed
· fully automatic integrated production line: fully automatic completion of decoiling, leveling, forming, punching, cutting and discharge, labor-saving, high production capacity, suitable for large-scale mass production;
· non-standard customized intelligent line: embossing, forming, welding, automatic coding, etc. can be added according to product demand Yes, suitable for complex profiles and high-end customized orders.
4.Give priority to the stability of equipment and reduce the loss of downtime to factory production.
Downtime is a direct loss. Reliable roll forming machine should have a solid fuselage structure, mature welding technology, small vibration of the whole machine, and no deviation, no deformation, and few failures in continuous long-term operation. Before leaving the factory, each roll forming machine of HENER Machinery will undergo load testing and accuracy verification to ensure that the equipment can be put into production stably after landing, and adapt to the normalized continuous production of the factory.
5. Look at the price rationally and reject the low price trap.
Many users compare devices and only look at the quotation, which is easy to fall into the misunderstanding of low price. Low-priced equipment often compresses the roller material, motor power, main frame material and control system cost. After being put into production: the finished product has poor accuracy, many scratches, high failure rate, frequent maintenance, non-standard production capacity, and the later hidden cost is extremely high. Real cost-effectiveness: matching production needs, stable operation, reliable accuracy, and long-term durability.
6. The essence of choosing equipment is to choose manufacturers.
After-sales industrial equipment is not a one-time sale, and after-sales and technical services are very important. Priority is given to source manufacturers with independent research and development, physical production and customization capabilities, so as to avoid intermediaries’ price increases and after-sales insecurity. Reliable manufacturer’s standard configuration: on-site plan docking, personalized customization, door-to-door installation and debugging, worker technical training, lifelong after-sales maintenance, equipment upgrade support.
