In the production of steel wire and wire ropes, high-speed, continuous operation has been recognized by many metal products companies. In recent years, it has been gradually realized through technological transformation. The steel wire spools are rewinded and processed in various processes. In the middle of the flow, the caster is a 'red line' that runs through the entire production process. The process of making the stranded wire through a water tank drawing machine and converting it directly into the strand or rope machine after winding by the spool , Partially realize the turn of the turn between the workshops, thus gradually canceling the traditional shafting process.
Since the spool take-up and the wire drawing machine match each other, they have a reliable winding mechanism and a constant tension winding function, so the winding quality is greatly improved, and the process and wire storage turnover cycle are reduced. However, in the quality monitoring It can only be sampled first and foremost. It can not be measured from the middle of the yarn like a winding-up, which makes it difficult for the operator to perform self-inspection in the production process. Therefore, in the continuous chemical character wheel rewinding line, the wire is measured online. Diameter and tolerance control become the necessary means in production. The two-way diameter measuring instrument performs non-contact online detection of the outer diameter of the steel wire in a high-speed and high-precision manner to meet the measurement requirements.
The bidirectional diameter measuring instrument is a device for detecting the outer diameter of the steel wire by a dynamic non-contact measurement method. The bidirectional diameter measuring instrument adopts a CCD image sensor and a one-chip computer processing system to realize bidirectional dynamic non-contact diameter measurement with an accuracy of 0.003 mm. Continuous measurement of wire diameter with high accuracy.
The entire system can be mainly divided into four modules: High-brightness, high-power LED green light as a point light source, equipped with an optical lens group for concentrating the auxiliary optical lighting module; Using a complex programmable logic device to drive the linear array CCD, the output synchronous sampling Clock to the high-speed A/D drive module; After the output signal of the linear CCD is pre-processed by the differential amplifier circuit, it enters the high-speed A/D conversion module for analog-to-digital conversion; Finally, the converted digital quantity is sent to the processor. The processing system carries out the operation processing, and the operation result is the data processing module of the liquid crystal display in real time.
Two-way diameter measuring instrument can realize outer diameter measurement in both directions of the steel wire, ellipticity measurement, audible and visual alarming when the measurement data is out of tolerance, and PID adjustment module, which can connect various external devices to form a closed-loop control for wire dynamic online Automatic control in detection. The jitter of the steel wire does not affect the measurement accuracy. The two-way diameter measuring instrument is an important equipment for quality inspection in steel wire production. The two-path diameter measuring instrument is a touch screen operation mode. It is displayed in Chinese, easy to operate and easy to use.
Two-way caliper instrument is installed on the wire drawing machine for continuous measurement. The wire diameter measured by the caliper instrument is compared with the measurement value of the micrometer.
Two-way diameter measuring instrument adapts to the production workshop environment, anti-jamming, anti-dust, long-term continuous operation can meet the expected requirements.
Two-way diameter measuring instrument on the wire diameter measurement and micrometer detection value.
Two-way caliper can display the real-time change of wire diameter in the process of drawing steel wire. When it exceeds the upper and lower tolerance of steel wire setting, it can carry out over-alarm.
Sudden rupture of the wire drawing core, if using the micrometer to measure the diameter of the line, the operator is difficult to find in time, and the two-way diameter measuring instrument can immediately give an over-alarm signal.
Two-way diameter gauge dynamic online, non-contact measurement and over-delivery alarm, automatic control features, can increase production efficiency, reduce scrap rate, and two-way diameter measuring instrument successfully developed a touch screen operation mode, easy to use.
