Modification and maintenance of a common punching machine CNC transformation He Su regret Wu Haibin 2 Department of Mechanical Engineering, Fuzhou University; 2 State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, Hangzhou 327 components and software design, 0 overview with the development of science and technology. A variety of CNC equipment; 4 emerged. Find the number of devices. It not only mentions the production efficiency, reduces the labor intensity, but also raises the processing precision, which also improves the quality of the product, which undoubtedly adds a strong vitality to the enterprise. However, the popularity of CNC equipment is limited by certain conditions. It is expensive for CNC equipment. In particular, small enterprises want to be completely updated and replaced. The funds are limited. It is the old equipment of the enterprise that is abandoned, and it is also the transformation of resources. Its automation capability saves the company money and makes full use of the existing resources to achieve the best of both worlds! This article will address the process of CNC transformation for the Dan 4 person type 4 ordinary punch. 1 scheme design can be active, and in the training period, Shijin motor must be finished. The 944 type punch is a kind of ordinary machine with relatively small power. Different molds can be used to process media of different materials and shapes. It is a very thin material. 1 is the application of the punch in a company to process round copper tin for welding. Before the transformation, it is manually fed. The mold itself has a clamping device. After the operator pulls the distance forward, the medium is automatically stuck. The punching speed of the punching machine has two speeds, one fast speed and one slow speed. In the case of hand 1 operation. Only use slow files. The fierce speed is too fast to punch 3 times in 1 second, and the clamping device of the mold itself can easily jam the medium. The purpose is to detect the boundary between the upper half cycle and the lower half cycle of the die motion, and send this signal to the microcontroller to complete the feed motion. Here, the stepping motor is selected from the top of the company's 89051 single-chip microcomputer, because it uses the 08 process, power saving, high load capacity, special station 1 memory technology. Make the wipe 4 of the program extremely easy and fast. and so. In recent years, a wide variety of component slotted photointerrupters have been produced in various fields. high sensitivity. No, delay, stepper motor is the hardware principle of the CNC system. Although the required persuasion rate is not very large, it is obviously impossible to directly drive with a single-chip microcomputer. Therefore, a driving component is added in the middle, and the current 4, brew driver is used. In order to improve the processing quality and increase the running speed, the press was technically modified. Adding an automatic feeding system, which can take full advantage of the punch's overall solution. The main drive shaft system base + change. Remove the clamping mechanism of the mold. The feeding device of the feeding system is realized by two rollers, and a stepping motor is used to drive one of the rollers, and the stepping motor is controlled by the single chip microcomputer to realize the entire numerical control feeding system. The hardware design of the CNC system is based on the feeding process of the punching machine. The movement of the stepping motor is intermittent. The driving current can be adjusted freely between 0 and 3 people, and the control part and the driving part of the drive adopt photoelectric isolation technology. Does not affect. 3 is the meaning of the numerical control system hardware. The system plays a key role, and its activity explores the principle of the body of the ice machine itself. It moves synchronously with the upper punch of the punching machine, so the movement of the test mold can be compared to the movement of the detecting rod. The infrared light-emitting diode is obtained by a photosensitive tube. The method of detecting the moving position of the movable rod is to fix a downward rotation on the rod. The output item on page 102 is the relay output. Can meet the on-off AC or virtual flow load; negative 哉. Can be mountain, direct drive; for a relatively load, such as papermaking, its resistive load is 2. points. The sense load is below 80 and the contact life is increased by the contactor as the power drive, and the input 4 is connected to the output as 10,000 times. This is the type of solenoid valve lights and alarms. 1 factory input and output point address allocation address description address description address description address description total stop 1 standing 1 set of mechanical hand extended back to the fire hand claw drop hand automatic conversion position, 1 mechanical hand shrink automatic cycle refers to single cycle arm upgrade single cycle Refers to automatic cycle 1 by water quenching to select arm drop manual refers to not mechanical hand stretched into position corner pulse arm left turn pavilion machine mechanical contraction in place counter reset arm right turn salt bath finger raised into position heating hand claw rising oil groove means arm lowered into position heating claw The descending water tank refers to the quenching hand claw rising nitrate salt furnace finger position 詈 1 quenching hand claw falling cleaning tank refers to the tempering hand claw rising in situ refers to the 3 control system element design according to the process sequence and control requirements described in the first part, it can be seen that The entire work process is divided into 39 steps to complete the continuous cycle work. According to its working characteristics, it should adopt the step-by-step control method to control it, and combine the stepping instructions with state transfer and other programming methods for software design. During the design of the program, the whole process of anger transfer, the work process can be divided into 39 program steps, using a single-flow cycle programming form state transfer conditions by the system's signaling device line, switch. Pressure relay. External hard devices such as button pulses and soft timer counters are provided. The state transition mode is used to program the tool, and the front and back steps are interlocked. According to the characteristics of step by step, the safety of the program is improved when the program is executed, and the conclusion is 4, after the technology is applied to the production system of the above production line. The production line overcomes the shortcomings of the control system composed of electronic logic devices and relays, which is vulnerable to the failure of the fault and maintenance difficulties, thereby improving the product quality. In addition, only by modifying the software, we can adapt to the new, artistic requirements. In many factories and mines in China, there are still a large number of old equipment and old production lines with good mechanical structure, if highly reliable programmable control is adopted. The computer control device and other technical control devices are technically modified to reduce the efficiency, and the easy to promote technical road 1 Zhao Yanxiang Xiangfa.

Beijing Machinery Industry Press, 1993, connected to the 9th narrow-band aging board. The movement of the light plate passes through the slot of the photointerrupter. and so. As long as the position of the photointerrupter and the length of the light barrier are reasonably determined, the demarcation point of the half cycle and the second half cycle of the inulin can be detected. In the second half cycle, the light blocking plate blocks the infrared light emitted by the pole tube. Therefore, the photointerrupter outputs a high level; in the upper half of the cycle, the light-emitting plate leaves the slot of the photointerrupter and the photo-sensing element is low-powered. 3 The design of the numerical control system is not complicated by the design of the cow system. The pulse signal output from the detection head is externally interrupted by the inverter through the inverter, so the entire program is divided into two parts: the main program and the interrupt service program. The feed rate of the medium is changed to the rotation angle of the stepping motor by the conversion department, and the following force is refined into the rotation of the stepping motor. > The ring number is stored as a tag value in a fixed address, and each execution cycle, The tag value is reduced, and 0 inch is waiting. If in the step of the stepper motor. When the MCU receives the interrupt of the detection head, it should immediately terminate the operation of the stepping motor, and at the same time detect the rising edge of the output signal of the detection head. After detecting the rising edge, reset the tag value, and end the execution of the interrupt service program and re-execute the main program. 4, the end of the scraping cluster 4; ice rushing through the NC re-election.
