Pipes are widely used in various industries, and the blanking process is the basis of the subsequent processing steps of the pipe. The accuracy and efficiency of the blanking process directly affect the quality of the products and the cost. The pipe is cut to length, mainly to cut the pipe to the required length. If the current pipe cutting method is still in the way of manual feeding and manual picking, it will not meet the needs of today's high-speed development of machinery, shipbuilding, military, petrochemical, energy, vehicle manufacturing, aerospace and Other industries. Therefore, it is very important to realize the automatic cutting and feeding. Through mechanical transmission or electrical control, a series of actions required by people can be completed according to certain rules, which can improve working conditions, reduce labor intensity, ensure production safety, improve production efficiency and product quality, and reduce raw material consumption and save. Equipment investment, reducing production costs. Automating the cutting of pipe fittings is the fundamental way and measure to improve the cutting efficiency of pipe fittings, improve the cutting precision and ensure the safety of cutting.
1 Design requirements 1.1 Overall layout design requires continuous and process of work process; high cutting efficiency; high cutting precision and strong stability; suitable for cutting of pipe fittings of various sizes and shapes; compact structure and clear hierarchy; convenient operation, maintenance and adjustment Long life and beautiful appearance.
1.2 Determination of the main parameters The original length of the cut pipe is not more than 12m; the diameter of the pipe is 15~50mm; the height of the rectangular pipe is 200mm, the width is 35mm; the length of the pipe is 2m; the height of the main axis of the table is 0.8. m. 2 Overall design and working principle of each part The overall structure diagram is as shown. The overall structure of the machine is mainly composed of a frame, a stepping motor, a ball screw drive pair, a moving pneumatic clamp, two fixed pneumatic clamps, a cutting wheel device and a control system.
2.2 Working principle of automatic feeding device Before cutting the pipe fittings, first rely on the positioning plate on the fixed starting fixture to put a plurality of pipe parts to be cut into the fixture and align them. After confirming that the pipe fitting is placed, the automatic cutting operation is performed by the control button starting device. When the pipe is cut, the moving pneumatic clamp first clamps the pipe, and then the stepping motor drives the screw to rotate through the coupling, so that the moving pneumatic clamp performs a certain axial movement on the frame rail to drive the movement of the pipe to be cut. . Then, the two fixed pneumatic clamps clamp the pipe fittings for cutting work, and at the same time, the moving pneumatic clamps are released and returned to the original position for the next feeding. The control system controls the rotation of the stepping motor to achieve precise cutting of various lengths of the pipe fittings. The precision reading error is 0.1mm. 2.3 The working principle of the clamping device is automatically controlled by the control system through advance programming, and the movement in the feeding phase. The pneumatic clamp and the fixed pneumatic clamp in the cutting stage position and clamp the pipe with compressed air.
2.4 The working principle of the cutting device uses a high-speed rotating grinding wheel to cut the pipe. The grinding wheel is made by bonding abrasives with fiber, resin or rubber. In the skilled operation, the grinding wheel can be cut quickly and accurately, and it is cut neatly and without burrs.
2.5 The working principle of the control system is pre-programmed to complete the control requirements of the reservation to realize the whole process automation of the machine. This is the core of the whole machine. Through the PLC control system, the supply and return of the stepping motor is completed, the clamping and relaxation of the moving pneumatic clamp and the fixed pneumatic clamp are completed, the cutting of the grinding wheel is completed, and the above actions are completed. At the same time, it also meets the indicators and requirements that each process needs to achieve.
After placing the pipe fittings into the fixture, first use the positioning plate for zero calibration, and then use the PLC control system to control the cornering of the stepping motor and the clamping and loosening of the clamp, as well as the fixed length cutting. Each link in the working process of the automatic feeding device requires the input and output of the corresponding signals, so as to smoothly complete the entire working process.
3 Design and calculation of main components 3.1 Drive design and calculation drive methods are various, you can choose linear motor drive, mechanical drive using electric motor, reciprocating magnet drive, hydraulic drive, pneumatic and so on. The automatic feeding device has two parts: the driving of the axial movement of the pipe feeding; the second is that the clamping and clamping movements are driven. Since the axial movement of the pipe needs to be stopped at multiple positions and the precision is required, the linear stepping motor is selected for driving, and the clamping and loose driving of the clamp is pneumatic.
3.2 Design of transmission mechanism for axial movement This project is mainly for the use of pipes for furniture. The original length of the pipe is 10m, the maximum cutting length is 2m, and the precision requirement is 0.1mm. Therefore, the axial transmission mode of the automatic feeding device adopts the ball screw transmission. . It can guarantee high precision, micro feed, efficiency (down to page 34) second, cultural consumption facilities and places, the consumption concept of friends and family and other factors are also important factors influencing residents' cultural consumption. The cultural consumption of residents and the cultural consumption places around the community are closely related to the environment and the completeness of the facilities. Most residents will adopt the principle of proximity when they are engaged in cultural consumption in their spare time. Therefore, it is necessary to strengthen the cultural foundation, infrastructure construction and improvement of related supporting services. To provide residents with convenient conditions for cultural consumption and to improve the satisfaction of residents' cultural consumption. The cultural industry itself has many public welfare natures. Only through the support of the government can we promote the vigorous development of the cultural industry. The cultural infrastructure is not only the carrier and platform for the realization of cultural consumption. The developed countries have many public cultural facilities such as museum art centers, and a large number of High-density cultural facilities have created favorable conditions for urban prosperity and provided a basis for civic cultural consumption. The choice of cultural facilities and places for consumption and the time for cultural consumption can be combined, and the consumption concepts of friends and family will affect each other.
Third, the average monthly consumption expenditure level is also a factor that cannot be ignored in the cultural consumption of residents.
The process of cultural consumption is actually a process of economic movement, and consumption must be carried out with savings. Cultural consumption is not a necessity. If savings are not enough, the first thing to control is cultural consumption. Cultural consumption activities are affected by the market economy and the law of value. The total consumption and structure of cultural consumption are restricted by the income level of the consumers and their income distribution.
Although economic income will affect the cultural consumption behavior of residents to a certain extent, it is not a key issue affecting consumer cultural consumption. Economic income has an impact on cultural consumption behavior, but it is not a decisive factor affecting the consumption of cultural products of residents. According to international experience, when per capita GDP exceeds 3,000 US dollars, cultural consumption will grow rapidly; when it is close to or exceeds 5,000 US dollars, cultural consumption will appear “wellâ€. To enhance the cultural consumption power of the citizens, we must first raise the disposable income of the citizens. On the one hand, the government can reform the income distribution system and establish a revenue growth mechanism to increase the income level of the citizens by expanding the income channels of the citizens; on the other hand, establish a sound income. The social security system, reducing household savings is also an effective way to increase disposable income.
Fourth, the price of cultural products (services) in research is not so important. On the one hand, the survey results show that most residents rely on traditional low-cost media to obtain information and meet spiritual and cultural needs, such as online, newspaper reading and so on. On the other hand, the proportion of student groups in the sample is higher, their consumption expenditure depends on parents, or parents are more willing to invest in cultural consumption for their children, and thus are not sensitive to the price of cultural products or services.
Fifth, media propaganda has a good guiding role. Some residents will carry out some unplanned consumption due to media propaganda, or carry out more cultural consumption on the basis of the original, and their consumption will also It has a certain diffusion effect on the relatives and friends around.
