Description

Technical Field

[0001] The present invention relates to the field of mechanical processing, and in particular to a device for real-time data collection and optimization of a numerically controlled spinning process. Background Art

[0002] Spinning is a metal plastic forming process that rotates the workpiece and applies local pressure to gradually adhere the material to the mold and form it. It has the advantages of high material utilization, good surface quality and high dimensional accuracy, and is widely used in the automotive, home appliance and military industries. In the current CNC spinning process, although the CNC system can control the basic processing parameters, it cannot effectively optimize the parameters during the processing. It only focuses on data collection and recording, and therefore inevitably encounters problems such as unstable processing quality or low processing efficiency, which can seriously lead to production safety hazards. For example, when the material properties of the workpiece change or tool wear affects processing, if the processing parameters are not adjusted in time, the workpiece may have dimensional deviations or surface unevenness and other abnormalities.

Then, an industrial computer processes the data and outputs a control signal, thereby dynamically adjusting the processing parameters of the spindle mechanism, tail top mechanism and spinning wheel mechanism, making the spinning process more accurate, efficient and safe. When the spinning pressure or temperature exceeds the safety warning line, the industrial computer can promptly control the electromagnet to adsorb the spring pin, so that the spindle can shrink in time under the action of the spinning pressure, thereby avoiding safety accidents such as workpiece displacement or tool breakage and flying out, and safety is significantly improved.

[0014] Wherein, the vibration sensor is arranged on one side of the base.

[0015] The present invention has the following beneficial effects:

[0016] 1. The industrial computer of the present invention integrates a data processing center, a parameter adjustment module, analog-to-digital conversion, and digital-to-analog conversion. It can analyze the process information transmitted by the sensor in real time. The data is processed and analyzed by the data processing center, and the process status of the spinning process can be quickly determined. Finally, a control signal is sent through the parameter adjustment module to dynamically adjust the processing parameters of the spindle mechanism, tail top mechanism, and spinning wheel mechanism, making the spinning process more accurate, efficient, and safe.

[0017] 2. The speed sensor of the present invention is arranged on one side of the main shaft, which can accurately measure the speed of the main shaft and transmit it to the industrial computer; after completing the data analysis, the industrial computer can timely control the speed of the motor so that the speed of the main shaft is within the set safety range, which can ensure the processing rhythm and the forming quality of the workpiece.

[0018] 3. The pressure sensor of the present invention is arranged at the mounting position of the first cutting wheel and the second cutting wheel, and the temperature sensor is arranged at the end of the extended fixed shaft, which can monitor the spinning pressure and the temperature of the workpiece in real time, and transmit the pressure and temperature information to the industrial computer; after the industrial computer completes the data analysis, if the pressure or temperature exceeds the range allowed by the current workpiece material and processing stage, the industrial computer can timely control the spindle speed and the feed amount of the spinning wheel mechanism, thereby reducing the spinning pressure and ensuring the processing quality and production safety.

[0019] 4. The displacement sensors of the present invention are respectively arranged on one side of the first feeding system and the second feeding system. The displacement sensors can monitor the feed amount of the rotary wheel mechanism in real time, so that the feed amount and feed speed are within the optimal range, and the forming quality of the workpiece is guaranteed.

[0020] 5. The wear sensor of the present invention is arranged on one side of the first cutting wheel and the second cutting wheel, which can monitor the wear condition of the cutting wheel and send the information to the industrial computer. When the wear degree exceeds the set specification, the industrial computer can stop the motor and feed system in time, which can effectively ensure the processing quality and avoid safety problems.

[0021] 6. The vibration sensor of the present invention is arranged on one side of the base. When abnormal vibration occurs during the spinning process, the vibration sensor can monitor it in time and transmit the information to the industrial computer. Under the control of the industrial computer, the motor and feed system can be shut down in time, which can effectively ensure the processing quality and avoid safety problems.

[0022] 7. The spindle of the present invention is an electromagnetically controlled retractable structure. When the spinning pressure or workpiece temperature exceeds the warning value or the vibration sensor detects abnormal jitter, the industrial computer will receive a signal and control the electromagnet to open. The electromagnet then absorbs the spring pin, and the spindle contracts in time under the action of the spinning pressure, which can avoid safety accidents such as workpiece displacement or tool breakage and flying out, and safety is significantly improved.

[0023] 8. The fixed shaft of the present invention is slidably connected to the sliding groove on the connecting shaft through the sliding teeth. The connection between the sliding teeth and the sliding groove not only ensures that the fixed shaft can move smoothly in the axial direction, but also drives the fixed shaft to rotate synchronously when the connecting shaft rotates, and the force is uniform and reliable.

[0024] 9. The present invention provides a compressed first spring between the fixed shaft and the connecting shaft, and the restoring force of the first spring is less than the axial extrusion force exerted on the fixed shaft during spinning. When the spring pin is released from the limit, the fixed shaft can move toward the motor under the action of the spinning pressure, thereby avoiding damage to the workpiece or the main shaft. When the abnormality is released, the fixed shaft moves toward the end of the workpiece under the action of the restoring force of the first spring, and is finally limited by the spring pin. The restoring structure is simple and reliable, and can simultaneously reduce the shear force exerted on the spring pin during normal spinning production, thereby greatly improving the service life of the spring pin.

[0025] 10. The fixed shaft of the present invention is electrically connected to the conductive stator via a conductive slip ring, enabling an industrial computer to control a high-speed rotating electromagnet. The spacing between the positive slip ring and the negative slip ring is greater than the width of the crimped stator. When the fixed shaft is squeezed and moved toward the motor, the crimped stator moves between the positive slip ring and the negative slip ring, or the crimped stator contacts only one of the positive slip ring or the negative slip ring, making it impossible to charge the electromagnet. When the abnormality is resolved, the fixed shaft is pushed back and reset by the first spring, and the spring pin can normally clamp the reset fixed shaft. The on-off control of the conductive slip ring is simple and effective, and the manufacturing and maintenance costs are greatly reduced.

[0026] 11. A shaft sleeve is provided on the outer side of the push rod of the present invention, and the shaft sleeve is slidably connected to the guide rod sleeves on both sides of the base through the guide rod; the shaft sleeve can increase the strength of the push rod, prevent the push rod from bending and deformation, effectively ensure the coaxiality of the push rod and the main shaft, and improve the processing accuracy and stability.
