The development of electronic technology, digital control technology, laser technology, microwave technology and high pressure jet technology brought new vitality to the automation, flexibility, intelligence and integration of wood furniture machinery.
The development trends at home and abroad are as follows:
1) High and new technology is involved in woodworking machinery to promote automation and intelligence. No matter the application of numerical control processing technology in woodworking machinery or the popularization of computer technology, it indicates that high and new technology is advancing to various technical fields. Electronic technology, nanotechnology, space technology, biotechnology and other technologies are or will be widely used in the field of woodworking machinery.
(2) More imitate metal processing means. From the development history of woodworking machinery in the world, wood processing methods tend to assimilate with metal processing methods, such as the emergence of CNC carving machine, for example, as we predict boldly that in the future, wood will be reshaped like forged ingots. More follow the example of metalworking.
From the perspective of domestic development pattern, wood processing enterprises or woodworking machinery and equipment tend to scale up, or they will be eliminated. At the present stage, backward and simple woodworking machinery still has a large market, and many woodworking enterprises are still carrying out labor-intensive operation mode. The future wood processing enterprises must take the road of industrialization and extensive development.
(4) Improve the comprehensive utilization rate of wood. The shortage of high quality raw materials has become the main reason to restrict the development of wood industry because of the decreasing of forest resources in China and even in the world. The main task of wood industry is to maximize the utilization rate of wood. Developing all kinds of wood-based panel products and improving their quality and application range are the most effective ways to utilize wood resources efficiently. In addition, the utilization rate of wood can be improved to a certain extent by developing the whole tree utilization, reducing processing losses and improving processing accuracy.
(5) Green Environmental Protection as China's government has promoted for the conversion of farmland to forests, natural forest protection project, forestry two major system construction and six projects construction, are wise environmental protection; Since July 1, 2002, wood-based panel product standards have been fully enforced, and production and sales are not allowed if they fail to meet environmental protection requirements. The development of wood processing industry must follow two principles. First, it is to protect the environment, obtain the natural resources to the minimum and reduce the pollution to the environment to the maximum extent. Secondly wood processing products must be harmless to human body or harmful degree control in the lowest range. Accordingly, the woodworking machinery that has vitality in the future and lumber industry product, it is to press ergonomic design necessarily, in accordance with environmental protection requirement.
(6) Improve production efficiency and automation. There are two ways to improve production efficiency: one is to shorten the processing time and cheapen auxiliary time. Shortening processing time, in addition to improve the cutting speed, increases the feeding, the main measures are a process of concentration, because the cutting tool, vibration and noise reasons, the cutting speed and feed cannot be unlimitedly increased, because many knives by type of concentrated with combination of machine tools and machining center has become the main development direction. Such as combined saw, milling, drilling, tenon, sanding and other functions of the double end milling machine; Edge sealing machine combined with a variety of processing techniques; It is a CNC machining center with a variety of cutting processes. To shorten the auxiliary working time is mainly to reduce the non-processing time. The auxiliary working time can be reduced to the minimum by using the machining center with a knife library or the automatic exchange table between the NC assembly line and the flexible processing unit.
1) High speed cutting.
(2) The manufacturing precision of some parts is relatively low.
(3) High noise level of woodworking machine tools.
(4) Woodworking machine tools generally do not need cooling devices, but entail chip removal and dust removal devices.
(5) The woodworking machine adopts more automatic feeding methods but less NUMERICAL control station processing methods.
At startup of oodworking machinery, its motor current will be higher than the rated 5-6 times, not only will it affect the service life of motor but also it consumes more electricity. The system in the motor will have a certain margin while the speed of the motor is fixed, but in the actual use process, sometimes at a lower or higher speed, the frequency conversion reform is very necessary.
The inverter can realize the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage frequency of the equipment, and it can provide the equipment with over current, over voltage, overload and other protection functions.
(1) Woodworking machinery operators must be highly skilled in the construction, performance and operation and maintenance methods of various wood machinery, and msut be responsible for the use of species-designated persons.
(2) When operating woodworking machinery, workers should wear work clothes, tie tight cuffs, female comrades must wear a good working cap, with braids into the cap; Do not wear gloves, scarves, etc.
(3) A test run must be conducted before the machine begins to work, and each component can be started to work only after it operates normally.
(4) Protective covers and protective plates shall be installed on shafts, chains, belt wheels, belts and other operating parts of woodworking machinery.
(5) In case of any abnormal conditions or other faults in the operation of the machine, it shall immediately cut off the power supply and stop for maintenance.
(6) For replacing the planer knife or saw blade, the main power must be cut off. Check the lubrication system of the machine before work every day.
(7) Stop wood machine when cleaning the wood machine workbench.
(1) Alarm failure
An overpass alarm indicates that wood machine has reached the limit position during operation. Please follow the following steps for inspection:
