Automatic terminal machine operation process and machining accuracy of parts

Automatic terminal machine operation process

1. Turn on the power switch of the automatic terminal machine, and the power indicator light is on. Pay attention to the abnormal noise inside and outside the machine. If there is a suspension, ask the mechanic to determine if it needs to be repaired.

2. Selecting the knife to be installed: It is operated by the designated personnel. Before the tool is loaded, it must be manually compared with the selected blade. If the comparison is correct, the knife can be loaded. After the tool is completed, the hand test must be used. Firstly, the automatic terminal machine is closed. Power, press the touch button, use the special wrench to shake the main driven wheel, so that the terminal presses the press stroke to the maximum. If the hand is not moving, consider whether the pressure is too large or other problems, check and debug to OK. Before each operation, check each locking screw and confirm that it is not loose.

3. Loading: Install the automatic terminal machine that needs to be hit. Use the hexagonal wrench to adjust the feeding platen so that the automatic terminal machine can pass easily. Visually check whether the feeding position is suitable. If not, adjust it and use the inner hexagon plate. Loosen the feeder lock screw, turn the adjustment lever to adjust it to the best condition, then lock the feeder lock screw to start the operation.

4. Test tension: After adjusting the machine OK, take the waste wire and test it, and carry out the tensile test. The main reference value is shown in the “Tursion Test Comparison Table”. The specific operation method is as follows. Press the pull test to reset the zero key to zero. The terminal wire is clamped and tested. If the measured tension is not within the standard range, the mechanic should re-adjust until the standard value is reached.

5, trial production 10PCS to send IPQC for the first piece of confirmation, inspection OK, in order to mass production, the operator must self-test the terminal is not covered with rubber, hanging neck and other bad, and once every 1 hour terminal Machine pull test. After the production is completed, the good products and waste products are sorted out, and the environmental sanitation around the fully automatic terminal machine is cleaned.

Machining accuracy of fully automatic terminal parts

(1) Dimensional accuracy. It refers to the extent to which the actual size of the part is close to the ideal size, as indicated by common dimensional tolerances. According to the national standard GB/T 1800. 1 - 2009, the standard tolerance is divided into 20 grades, namely IT01, ITO, 171 YIT18. IT indicates standard tolerance, and Arabic numerals indicate tolerance level. The larger the number, the larger the tolerance value is. The smaller the dimensional accuracy is. 1TOI---IT13 is used for the matching size. The commonly used matching dimensional tolerance is below IT5; IT14-ITIS Used for non-mating dimensions.

(2) Fully automatic terminal machine shape accuracy. It refers to the extent to which the actual shape of the part is close to the ideal shape. Shape tolerances include straightness, flatness, resilience, columnarity, line profile, and face profile.

(3) Stereo tolerances. It refers to the extent to which the actual wall between the surface, axis or plane of symmetry of the part is close to the ideal position. Terminal machine position tolerances include parallelism, verticality, inclination, position, concentricity, symmetry, mouth bounce and full bounce.

Stripping the terminal machine to introduce the terminal machine can be divided into which

Fully automatic terminal machine: It integrates a server (silent type) terminal machine. Its operation principle is different from that of a general terminal machine. It only needs to give the server a message. This information is transmitted to the motor and the automatic terminal machine. Can be an action. The entire job ends automatically.

Semi-automatic terminal machine: generally referred to as terminal machine, it is also the type of erected desktop terminal machine that we often see on the market today. This type of terminal machine has a pedal-type power-off gathering because of the terminal machine. During operation, the motor motor is continuously operated. Each time the pedal is pressed, an "O" power-off signal is given to stop the operation, which is much lower than the price of the fully automatic terminal machine.

The terminal machine needs to be eliminated when it is used.

In production, the commonly used cutting wire machine - terminal machine, there will always be such a problem when it is used. If you want to use the machine to troubleshoot and make the machine work better, we need to take care of several core faults with great care. What core faults should we pay attention to? Xiaobian will give you a detailed discussion.

First of all, the terminal machine often suffers from the death of the terminal when it is used. The terminal machine transmits the voltage of the external wire or cable, as well as the current or signal to the corresponding touch component of the connector. In this process, it is easy to appear that the appearance of the machine is unreasonable or the assembly is not proper, the use environment is bad, etc. The phenomenon of poor contact affects the use of the terminal machine.

Secondly, the insulator of the terminal machine has excellent electrical function. If it is used, the metal residue appears on the exterior or inside of the insulator, or the machine is affected by dust, flux and other pollution, and the organic data is separated. The combination of the harmful gas adsorption film and the external water film to form an ionic conductive channel and other insulation aging phenomena may constitute a short circuit of the machine or a phenomenon of poor insulation such as leakage or breakdown, which is not conducive to the operation of the machine.

Third, whether it is a fully automatic terminal machine or a terminal machine, the insulator also plays a fixed role. If the fixing is poor, it is easy to cause a machine malfunction.

Terminal machine connection skills and performance characteristics decomposition

[Puncture connection method of terminal machine]

In our daily lives, electronic devices are always used. Some electronic devices use a rechargeable type, and another electronic device uses a battery. Among them, no matter which kind of electronic equipment, the terminal is generally used. What is a terminal? The terminal is a component that is associated with the battery and other conductors, which is very helpful for the use of the electronic device.

Puncture connection, also known as insulation displacement connection, is a novel end technology invented by the United States in the 1960s. It has the characteristics of high reliability, low cost and convenient use. It has been widely used in various printed circuit board terminals. Cold-pressed terminal, cold-pressed end, and ring terminal. It is suitable for the connection of ribbon cables.

The connecting layer does not need to be stripped of the insulating layer of the cable, and the "U"-shaped contact spring of the connecting terminal penetrates into the insulating layer, so that the conductor of the cable slides into the groove of the contact spring and is clamped, thereby making the cable A close electrical connection is formed between the conductor and the terminal spring. It requires only simple tools, but cables with specified wire gauges must be used.

Terminals are still very widely used in real life. Many industrial products, as well as information transportation, are inseparable from the use of terminal blocks. Terminals also have a lot of techniques and processing methods, such as winding, such as welding, such as crimping. Semi-automatic terminal machine manufacturers provide high-quality automatic terminal machines, piercing terminals, semi-automatic terminal machines, terminal molds, terminal copper strips. Welcome to inquire.

[Type and function of terminal machine]

In many industries, the work of a piece of mechanical equipment always needs to be used in conjunction with other mechanical equipment to achieve the final communion result. There is an old saying that "there is a specialization in the industry." People are like this, and so is machinery. Different mechanical response work is professional. Like the current wire harness industry, fully automatic terminal machines and computer wire strippers are also a good pair in production. What is the role of their respective roles?

The computer wire stripping machine is an electronic wire processing equipment that is aligned within 3mm2 line. It can cut 15 meters in cutting and can reach 120mm in stripping length. 32#-14# wire can be processed freely without damaging copper wire, precision It can be self-regulated within 2 meters without any mistakes, which greatly reduces the labor intensity of workers and ensures the degree of wire processing.

Briefly speaking, the terminal machine is a kind of machine used for wire processing. It can press the hardware head to the wire end and then conduct it. The terminals that are driven out by the terminal machine are generally convenient for the connection. The two wires can be connected together without being welded, and only need to be unplugged when the time is removed.

The work of the automatic terminal machine and the computer wire stripping machine is like when we are cooking, one person is responsible for cutting vegetables, one person is responsible for cooking, two machines work together, and the production of the online beam industry cannot be combined. The missing part helps people to produce more quickly.

How to change the blade of the automatic terminal machine?

When using the terminal machine for production and processing, the use of the tool is very important. If the thickness and size of the wire are different, the blade of the terminal machine needs to be changed, which is very simple; and the die of the terminal machine is mainly processed by different types. For wire, different types of molds are used.

1. Disassembly and installation of the mold:

Case 1, if you want to delete the mold, you should first adjust the machine to manual mode, press the "down" or "down" punch, when you see the high-end die rotate the mold lock lock counterclockwise, pull, keep the lock The mold is then pushed horizontally to the left.

Case 2: If you plan to install the mold, you should first remove the mold lock, the level of the mold is then pushed to the right, and punching into the top of the mold is enough (if the punch has sunk, move the hand tool inside the mold gate) Ascending will require a too high or too low punch, adjustable in manual mode to the appropriate height), then into the mold fixing fixture and tighten the clockwise rotation.

2, the installation method of the upper and lower blades:

The terminal machine is equipped with 2 knives (upper boring tool) and 2 knives (lower knives), or some specific terminal machine dies have only one knives.

3. The mold filling terminal to be put into use:

The adjustment of the terminal machine blade has been completed, the terminal can be placed in the mold, the front needs to be placed on the frame, fixed by the guide plate cutter, and the circuit terminal.

4. At the end position of the drive pin and the hole cover:

Pull out the "drive pin fixing screw" so that the "drive pin and hole cover" and the only insert material can have holes just in the terminal, then the lock drive pin fixes the middle of the screw. Will go to "end back eccentric", then go to manual mode will go to the head to adjust to low, the terminal position is lower than it, if not below the need to tighten the "screw fixing screw", then turn "driver needle adjustment" by hand The screw is used to observe the tightness, so that the terminal is lower than the die, and the fixing screw for locking the screw can be used. Then you need to adjust the hole cover hole with the material such as the next block and the hole cover.

Steps for replacing the blade with the automatic terminal machine:

1. Unplug the mechanical equipment and let the terminal machine stop.

2. Locate the appropriate screwdriver to loosen the place where the blade is fixed.

3. Take the blade down and replace it with another blade;

4, according to the original steps to install directly on the line.
