How to choose a high quality roll forming machine?
【The present situation of roll forming machine at home and abroad】
Where does the roll forming machine go wrong?
Spindle roll bearing shear defective
Then, a good roll molding machine need to have what conditions?
How do we choose a good roll forming machine——
With the development of economy, the construction of light steel structure in construction application expansion, increasing demand for production equipment, the production equipment automation requirements also more and more high, each big company investment, research and development of various types of caigang pressure plate (tile) production line and C, Z section steel (purlin) production equipment, use of simple operation, increase productivity, reduce production cost, etc. Existing various types of color steel pressure plate (tile)C, Z section steel (purline) automatic control production lines are in the leading position at home and abroad, with lightweight structure, reasonable design, and constantly updated progress and light steel builders and products manufacturers favor and praise.
However, in the rapid development of the economy today, there will always be some black heart manufacturers do some black heart earn money.
Today small make up for you to reveal a little bit about the industry. Small make up in XXX factory made before a month-long investigations, during the one month small make up striking finding their production machines are very unprofessional, used by the assembly of parts and materials is also a patchwork, is a parts factory, doesn't care about the subsequent assembly machine and used in the process of using an integrated and ductility.
Even more than that, some dark enterprises will have some shoddy phenomenon! Driven by profits, these enterprises lower their heads towards money, turning spindles, rollers, molds, bearings... These have been replaced by cutting corners, resulting in the subsequent production process of the customer product quality is not up to standard, process accuracy can not reach, fault repair rate is high and so on.
So how can we buy a really good roller press? It's easy! Next small series will sort out the most concerned about a few questions, for everyone to answer one by one.
Q: what are the requirements for a good roller mill?
A: to find the machine in your mind, you must first find A factory that doesn't cheat you.
Xiaobian think this manufacturer should do the following:
1. Have a personalized and customized production process.
2. Exquisite processing technology to ensure the precision of equipment requirements.
3. Strictly specialized quality inspection, ensure the tolerance requirements of equipment parts and components, and strictly control the quality.
4. Not only pay attention to the precision of the machine, but also attach great importance to the assembly and debugging process, because the overall assembly of the whole machine is the last and most important stage in the production process, which includes asembly, adjustment, inspection and commissioning.
5. Perfect after-sales service system, provide various emergency solutions for customer service.
6. Have a scientific, standard and streamlined production system.
If you find a manufacturer that meets all the above requirements, then congratulations!This is indeed a factory that is not a pothole.
But Xiao Bian believes that people who read this chapter are not just trying to achieve this effect!What we are asking for is a machine with a higher-end atmosphere (good quality, excellent price, high precision)!
Q: what is the process and production process of the roller press?
A: after the above knowledge about manufacturers, the next point about professional. Only when you have a real understanding of the small series, you can achieve the purpose of reading this article.
Roller processing technology:
(1) production process of cold bending equipment:
The production process of cold bending equipment is as follows: uncoiling, leveling, online servo feeding punching, forming rolling, straightening, cutting off with fixed size, packaging and later spraying treatment.
The corresponding equipment is: uncoiler - leveling machine - servo feeding device - press - cold bending rolling set - straightening head - hydraulic cutting device and hydraulic station - baler or other ancillary equipment.
(2) cold bending equipment design and production should pay attention to the problem:
The tolerance range is reserved according to the size of the drawing, so as to ensure the accuracy after processing, so as to avoid the obvious influence on the model or equipment caused by the accuracy tolerance during the test run. The hardness range shall be adjusted and tempered or quenched in strict accordance with the specified requirements to ensure the hardness of shear blades, spindles and rollers.
Production process of roller press:
1. Discussed the version with the customer, customized and changed the design and construction scheme according to the customer's requirements, including: uncoiling structure, servo feeding punching, roll forming, hydraulic scale cutting, molding speed, automatic stacking, etc.
2.Selecthighquality h-shaped steel as the rack part of the equipment to ensure the accuracy of welding process.
3. Tolerances reserved for blank size include: rack, spindle, wall plate or memorial arch, roller, shear blade, etc. Strictly in accordance with the requirements.
4. The workpiece that needs to be quenched or quenched in the equipment shall be heat treated according to the specified requirements according to the different materials.
5, the use of advanced CNC, gantry, CNC lathe, boring machine and other equipment absolutely ensure the workpiece processing size requirements in the process of production and processing, to ensure that after installation and debugging due to production and processing parts defects affect the plate forming effect.
6, the use of bearing: choose domestic quality assured brand (wafangdian bearing, Harbin bearing, etc.), to ensure that the bearing seals and lubricants can fully play their due performance, improve the production efficiency of the equipment.
7. Selection of motor: it can completely meet the requirements of mechanical characteristics of production machinery, such as the required working speed, speed regulation index, acceleration, starting and braking time, etc., to ensure that its power is fully utilized.
Choose the motor with reasonable structure, reliable operation, excellent protection level and high cost performance to prolong the service life.
8, how to choose the hydraulic station, generally according to the speed and cylinder size, to calculate the pump flow, and then select the pump (according to the pump power select motor), design the size of the oil tank (select oil tank accessories), select the control valve, select the pipeline and joint. Under the operating conditions of the main engine, the flow of the actuator, the larger the flow required, of course, the system will be larger, the valve block is larger, the oil tank is larger, of course, the hydraulic station is larger.
Structure: mainly in the form of the structure of the pump, installation position and cooling way to distinguish, according to the structure of the pump installation position can be divided into three:
(1) upper vertical: pump device vertical installation on the tank cover plate, mainly used for quantitative pump system.
(2) the position of horizontal: horizontal pump device installed in the tank cover plate, mainly used for variable pump system, easy to adjust the flow.
(3) side-mounted: the pump unit is mounted horizontally beside the tank on a separate basis. Side-mounted can be equipped with standby pump, mainly used for the system with the tank capacity of more than 250 liters and the motor power of more than 7.5 kilowatts.
Cooling methods can be divided into two types:
(1) natural cooling: by the fuel tank itself and air heat exchange cooling, generally used for the tank capacity less than 250 liters of system.
(2) forced cooling: take the cooler for forced cooling, generally used for the tank capacity of more than 250 liters of system.
Knowing the above professional knowledge, xiaobian believe you will be more easily to get the roller press you want. But remember that machines have a bad day, just like food has a shelf life. So how do we deal with this in the easiest, most cost-effective way?
Q: the molding machine should be maintained and how can we use the sale to maximize profits?
A: maintenance of molding machine
1. Check the electronic control device of mechanical equipment to ensure the normal operation during the production period, and check the normal operation of indicator lights during the trial operation of the electronic control cabinet.
2, for its oil road, mainly to see whether there is no oil leakage and other problems, such as timely treatment, can not delay, and also to prevent the deterioration of oil should be immediately replaced once found.
3, the transmission part of the machine is well lubricated, refueling or changing oil on time, continuous oil, dry friction phenomenon, normal oil pressure, bright oil mark, smooth oil road, oil quality meet the requirements, oil gun, oil cup, linoleum clean.
4. The hydraulic oil used by the molding machine should be replaced regularly and the mailbox should be cleaned at the same time.
5, the cleaning of the equipment is to give the equipment a good appearance, a good working environment, clean including the inside and outside of the equipment clean, screw, rack, tile oil hole and other places without oil, no oil leakage, the chip around the equipment, debris, dirt to clean; Ensure that the operation of the equipment can be done without any risk. Tidy tools, accessories, workpieces (products) should be neatly placed, pipelines, lines to be organized.
6, safety comply with the safety operating procedures, not overload use of equipment, equipment safety protection device is complete and reliable, timely eliminate unsafe factors. When the equipment is used, it must be operated in accordance with the production instructions. The safety of production personnel is the weight of each factory.
