Why is the wire diameter of the extrusion machine unstable?
Release time:
2023-12-11
If it is found that the wire diameter is unstable, first check whether the efficiency coordination of each step of the equipment is consistent and whether there is a large fluctuation of the local damage value, which can be analyzed from the following points:
(1) Traction part (2) Electronic control part (3) Extrusion die (4) Main machine speed (5) Screw barrel (6) Reduction box ratio (7) Screw problem (8) Process temperature
(1) Traction part: The unfinished cooling forming wire harness is stretched and deformed due to too fast tractor or too slow, which causes the material opening compound to adhere and not expand. And whether the tension of the rear winding reel can be wound smoothly.
(2) Electronic control part: whether the parameters set by the control system meet the current process requirements of wire harness production, whether the program logic is correct, and whether the steps of the equipment are synchronized
(3) Extrusion mold: whether there is damage during the use of the mold, whether the mold leaves the factory with defects, and whether the discharge port is smooth and free of foreign matter
(4) Main engine speed: whether the abnormal setting of the frequency converter leads to insufficient torque and the speed does not meet the current discharging standard of the wire harness compound
(5) Screw barrel: The equipment is operated for a long time, resulting in excessive wear and tear, resulting in serious material backflow and unstable internal pressure, resulting in uneven discharge.
(6) Ratio of reduction gearbox: whether there is abnormal noise in the operation of reduction gearbox and whether the oil level is at the standard ruler position. Unstable gearbox ratio output will also lead to unstable rear-end discharge
(7) Screw problem: Whether the compression ratio and structure of the current screw are suitable for this rubber compound can be removed from the mold and discharged from the extruder to see if there is instability. If it is still intermittent, it can basically be ruled out that the mold causes are concentrated on the motor, reduction box, frequency converter and screw barrel heating for investigation.
(8) Process temperature: whether the temperature setting of each mold section is reasonable, whether the heating is abnormal and whether the heating ring is damaged

What inspections must be done in the whole process of high-speed stranding machine application
Stranding machine alias high speed stranding machine. Wire binding machine. Nim wire machines are commonly used in various types of soft or hard electrical conductor wires (copper core wires. Wire-coated wires. Electroplated tin wires. Copper-clad steel. Copper-clad aluminum, etc.) and stranded wires for electronic wires. Today, let's specifically talk to you about what checks must be made in the whole process of high-speed stranding machine application? High Speed Stranding Machine. jpg Check whether all parts of the equipment are normal, and install the pitch wheel according to the provisions of the process documents. When installing the pitch wheel, loosen the clamping screw at the passive wheel (the pitch wheel is the rotating shaft), push the passive wheel away from the original position, and then install the pitch wheel. Be careful to point the health groove first and then gently hit the pitch wheel to make it accurately positioned. Do not blindly follow the trend and cause the pitch wheel to be destroyed. The location of the gear ring is clear with the location of the pitch wheel. When the pitch wheel is installed on both sides (with the blue baffle plate as the inner side), the gear ring is installed on the inner side; on the contrary, it is installed on both sides. After the pitch wheel is installed, pull back the passive wheel to make it fit with the pitch wheel properly (not too tight or too loose), and tighten the clamping screw of the passive wheel. Proper installation of pitch wheels shall be determined. It is also necessary to check whether the high temperature resistant grease in the full-automatic lubricating grease cup on the top of the machine is lacking. When the lubricating grease in the lubricating grease cup is smaller than the lower line on the cup body, be sure to give oil. The amount of oil cannot make the leather pad on the lower layer of the cup higher than the red bar on the cup body. There is no need to fill grease at the worm gears of each transmission system in the cradle of the stranding machine. It is OK to have a cleaned grease film on the main rod at the cable arrangement, and there is no need to add more.

Wire and cable extruder how to do daily maintenance
The wire and cable extruder belongs to the mechanical professional machinery and equipment. After a long period of use, it is inevitable to do a good job of maintenance. So how can we do a good job of daily maintenance for the wire and cable extruder in general? 202109160952542426 (1).jpg (1) Daily maintenance is a habitual routine work, which does not account for the operation and construction time of machinery and equipment, and is generally carried out during the start-up period. The key is environmental protection equipment, moistening all fitness sports parts, tightening the externally threaded parts that are easy to loosen, immediately checking, adjusting motors, control instruments, spare parts and pipelines in each work, etc. (2) No open operation is allowed to prevent the screw and the machine from rolling. (3) If the extruder produces abnormal sound during operation, it should be parked immediately for inspection or maintenance. (4) Resolutely prevent stainless steel or other dirt from falling into the silo to prevent damage to the screw and barrel. In order to prevent iron dirt from entering the charging cylinder, a magnetic absorption member or a magnetic frame can be installed at the charging outlet of the charging cylinder to prevent impurities from falling into the raw materials. (5) Pay attention to the cleaning of the working environment, and do not let the waste residue penetrate into the packing material to block the filter element filter, thus endangering the production volume, quality and frictional resistance of the lifting machine head. (6) For the DC motor that pushes the screw to rotate, it is necessary to check the damage and touch conditions of the carbon brush. Whether the grounding resistance value of the motor is at the standard value above should also be measured accurately. In addition, it is necessary to check whether the electrode connection line and other components are rusted, and select safeguard measures. (7) Specific full-time personnel to undertake the maintenance of machinery and equipment. And the detailed records of each maintenance and repair status shall be included in the equipment maintenance archives of the processing plant. The above is the "wire and cable extruder how to do daily maintenance?" All the content, looking forward to helping everyone. If everyone also has other knowledge about wire and cable extruders need to know, warmly welcome to pay close attention to this site continuously. If you don't understand, you can understand our online customer service, and we will serve you wholeheartedly.
