Adjustment of wire harness processing equipment on product production

In the current domestic wire harness processing market pressure, such as tin-plated such composite steel strip in a number of wire harness factory is still used, even including some large wire harness processing plant. The quality of the harness has strict requirements of the user, the need to control the performance of the raw materials to ensure that the long-term service life of the harness. Polyethylene should have you show rheological properties, good polyethylene has a uniform and stable melt index. Suitable for different bundle diameter, can achieve a certain extrusion speed. Stable extrusion flow, grounding wire processing to ensure product geometry, appearance of the integrity of the product, that is, the product will not appear surface roughness, wrinkles, bamboo, blistering, localized thinning and so on. In order to adapt to large-scale production, as a wire harness sheathing material between the batch performance stability is also critical, because the instability between the batch and frequently adjust the extrusion process will inevitably affect the terminal performance of the wire harness. Poor quality sheath material, especially recycled sheath material within each batch and batch to batch is very difficult to ensure the stability of its performance, so the extrusion of wire harnesses in the processing of the sheath, the need to constantly adjust the process parameters, which will affect the stability of the quality of the harness. The idle process is set to a lower priority among all processes, and thus gets executed when other processes are idle, and its function is to make the indicator light blink as an indication of the load condition. The results of the modal analysis have guided the selection of materials and the optimization of the geometry, resulting in a reduced mass and a more rationalized layout of the load-bearing platform while meeting the strength requirements. The dynamic characteristics of the whole load-bearing platform are also improved with the adjustment of the layout of the reinforcement and the reasonable distribution of the mass, and the first six orders of the load-bearing platform are above the frequency, which is far away from the frequency of the Lupu excitation signal, and the dynamic performance of the model meets our requirements, and it can provide a good load-bearing environment for the test. To detect the connection information of the selected numbered harness, turn the function selector switch to the detection input and run the test bench. If the test result is qualified, the instrument prompts qualified; if the test result is unqualified, it prompts error, and at the same time, it displays the terminal position where the error occurs and the type of error in the unqualified wire position and error type display area, in which the error code indicates short circuit, indicates broken circuit, and the number with a decimal point is the on-resistance is too large, and the number is the resistance value measured. The type of error detected is. Another important feature is the skin effect, which is a phenomenon that at higher frequencies causes the current flowing through a round conductor to flow onto the surface of the conductor, making the conductor almost as if it were a hollow tube, and it is this effect that makes coaxial wiring harnesses possible. This effect increases the surface resistance of the conductor at high frequencies and causes a phase shift. The elaboration of the wire processing and wire harness automatic test system platform is based on the cable tester of course, can also be other models of similar testers, through the design and production of special test adapter to realize the system test. The tester consists of a host computer and a number of test expansion modules, each test expansion module has a core test interface, a total of high-speed relays arranged in a matrix, a host computer can drive the test expansion module.
