Description

TECHNICAL FIELD

[0001] The present application relates to a kind of bar wire sheared material identification system's inclusion removal device. BACKGROUND

[0002] In the bar wire production process, generally application diameter gauge is detected on-line to product, in prior art diameter gauge is mainly used in rolling process size detection and screening abnormal product, and cannot provide timely and effective data for automatic control, and the measurement accuracy of diameter gauge is susceptible to the influence of environment and appears fluctuation. Bar wire in the rolling process high temperature can produce hot airflow, and vibration is generated while running at high speed. The higher the running speed, the faster the vibration frequency, and the more difficult to guarantee the measurement accuracy. Traditional screw thread steel because of complex shape, diameter gauge cannot be detected in the high-speed motion state of screw thread steel. Screw thread steel general appearance size detection is sampling inspection, i.e. taking finished product from production line, using special outside diameter measuring tool to measure. If artificial monitoring is not timely, it will cause the existence of defects in appearance quality of waste.

[0003] Therefore, a system for identifying sheared material generated in the rolling process of bar wire by using visual recognition technology is developed (has another case application). First, the sheared material is collected by the sheared material collecting device arranged under the flying shear chute and transported to the designated detection platform. After the sheared material is visually recognized on the detection platform, including the length, outside diameter, crack, groove type, etc. of the sheared material, the processed data information is finally transmitted to the control system to realize high-precision detection of bar sheared material, and finally transported to the waste frame through the chute. However, the inclusion attached to the surface of the sheared material usually interferes with the visual recognition, thereby affecting the visual recognition in the later period. SUMMARY

[0004] In view of the above problems, the present application relates to a kind of bar wire sheared material identification system's inclusion removal device.

[0005] To achieve the above purpose, the inclusion removal device of the bar wire sheared material identification system of the present application, the bar wire sheared material identification system comprises: an angle inclined chute, a first collecting frame is arranged at the lower opening of the chute; a second collecting frame is arranged on one side of the chute, and a discharge port is arranged on the chute corresponding to the second collecting frame; a visual recognition device is arranged at the discharge port;

[0006] A rotating plate is arranged on the chute bottom plate at the discharge port perpendicularly to the chute bottom plate,

[0007] A driving device drives the rotating plate to rotate along the chute bottom plate to be located at the first working position or the second working position; when the rotating plate is located at the first working position, the material in the chute falls into the first collecting frame along the chute; when the rotating plate is located at the second working position, the material in the chute falls into the second collecting frame along the chute and the rotating plate;

[0008] The inclusion removing device is arranged at the discharge port and comprises a guide device, and a plurality of compressed air nozzles are arranged in the guide device, and the air inlet ends of the compressed air nozzles are communicated with compressed air pipes.

[0009] Further, the compressed air nozzles are arranged towards the discharging direction.

[0013] Further, an opening is arranged on the chute, and the spray head is arranged in the opening.

[0014] The high-pressure air is sprayed from the compressed air nozzles arranged on the guide to remove the inclusions on the surface of the sheared material, and further, the sheared material can be sprayed with water by the spray head to reduce the temperature, so as to facilitate the subsequent visual identification. After the inclusions are removed, the sheared material is visually identified at the discharge port, and the length, outer diameter, crack, groove and the like of the sheared material are identified, and finally the processed data information is transmitted to the control system. After the data information of the sheared material is collected, the rolling mill control system judges the adjustment amount required by the rolling mill roll gap, controls the feeding time of the blank, controls the rolling mill control system to adjust the rolling mill roll gap without load in the rolling gap of the two blanks, and realizes the high-precision detection of the sheared material of the rod.

[0031] When the sheared material needs to be detected, the rotating plate 2 leans against the fixed plate 1, and the sheared material falls from the flying shear and is collected outside the gate 5 at the discharge port through the rotating plate 2. When the sheared material slides through the v-shaped groove 7, it is recognized (photographed or filmed) by the visual recognition device 9 arranged on the v-shaped groove 7, and the sheared material is discharged into the second collecting frame 10 through the v-shaped groove.
