Description

Technical Field

[0001] The present invention relates to the technical field of spring wire processing, and specifically, to a straightening device for spring wire. Background Art

[0002] During the manufacturing process of spring wire, due to the influence of various factors such as material properties, processing technology, and equipment precision, shape deviations such as bending and twisting often occur. These deviations not only affect the dimensional accuracy and appearance quality of the spring, but may also lead to a decline in the mechanical properties of the spring, thereby affecting its service life and reliability. Therefore, straightening the spring wire is a key link to ensure product quality. However, the existing straightening devices have the following problems when straightening spring wire: 1) Insufficient straightening accuracy, resulting in the wire still being bent, wavy or locally deformed after straightening (caused by roller or die wear, improper adjustment of roller pressure, too fast straightening speed, etc.); 2) Surface damage, resulting in scratches, indentations or coating peeling on the wire surface (caused by rough roller / die surface or adhesion of metal chips, excessive straightening pressure causing plastic deformation, insufficient lubrication, etc.); 3) Wire breakage or excessive deformation, the wire breaks or the cross-section deforms during the straightening process (the straightening device is overloaded, the guide wheels are misaligned). In view of this, there is an urgent need for a straightening device for spring wire to solve the above problems. Summary of the Invention

[0034] The specific embodiments of the present invention are as follows:

[0035] A support component for fixedly supporting the spring steel wire 5.

[0036] Further, the support component includes two vertically parallel support rollers 3, and the spring steel wire 5 passes between the two support rollers 3.

[0037] A correction component, including a plurality of correction units, each correction unit consisting of a pair of oppositely arranged correction rollers 4, and all correction units are used to correct the spring steel wire 5.

[0038] Further, the number of correction units is greater than or equal to 3.

[0039] A driving component, connected to the support component and the correction component, for driving the support rollers 3 in the support component and the correction rollers 4 in the correction component to rotate, ensuring the smooth conveyance of the spring steel wire within the correction device.

[0040] Further, the driving assembly includes a variable-frequency motor 7 and a frequency converter 8. The frequency converter 8 is electrically connected to the variable-frequency motor 7. The variable-frequency motor 7 is connected to both the support roller 3 and the correction roller 4 through a chain.

[0041] The control assembly includes a control module 13. By collecting the torque sensor data in the driving assembly, the pressure sensor data in the correction assembly, and the position sensor data during the conveying process of the spring wire, the correction device is adjusted once.

[0042] The detection assembly includes a laser rangefinder 9 and an image module 10, which are used to perform quality detection on the corrected spring wire 5 to obtain a detection result. Based on the detection result, the correction device is adjusted a second time.

[0043] Further, the laser rangefinder 9 is used to measure the diameter and straightness of the spring wire 5, and the image module 10 is used to detect the defects and deviations on the surface of the spring wire 5.

[0044] It further includes: a base 1 and a bracket 2. The bracket 2 is fixed on the base 1. A hollow area 6 is provided inside the base 1. The driving assembly and the control assembly are both installed in the hollow area 6. The support assembly and the correction assembly are both installed on the base 1. The detection assembly is installed on the bracket 2.

[0045] Further, a plurality of sliding grooves are provided on the base 1. All the support rollers 3 and all the correction rollers 4 are slidably connected to the corresponding sliding grooves and are all equipped with locking mechanisms.

[0046] Among them, the locking mechanism includes an electric push rod 12 and a baffle 11. One end of the electric push rod 12 is connected to the top of the sliding groove, and the other end of the electric push rod 12 is connected to the baffle 11.

[0047] Further, the device further includes a temperature sensor, which is installed on the base 1 and is used to monitor the temperature of all the correction rollers 4.

[0048] The working principle of the present invention is as follows:

[0049] The support assembly is used to fix and support the spring wire 5 to ensure its stability during the processing. This assembly includes two support rollers 3 arranged in parallel. The spring wire passes through between the two support rollers 3. By adjusting the position and spacing of the support rollers 3, spring wires 5 with different diameters can be adapted. Specifically, the position and spacing of the support rollers 3 are adjusted by the electric push rod 12 pushing the baffle 11.

[0050] The calibration component is the core component for calibrating the spring wire 5. It includes multiple calibration units, and each calibration unit consists of a pair of oppositely arranged calibration rollers 4. The surface of the calibration roller 4 is specially treated, with high hardness and wear resistance, and can apply uniform pressure to the spring wire 5, thereby achieving calibration. The calibration units are arranged in sequence along the conveying direction of the spring wire 5. Through multi-stage calibration, the bending and twisting of the spring wire 5 are gradually eliminated.

[0051] The driving component is used to drive the rotation of the support roller 3 and the calibration roller 4 to ensure the stable conveyance of the spring wire 5 within the device. This mechanism uses a variable-frequency motor 7 as the power source, and controls the rotation speed of the variable-frequency motor 7 through a frequency converter 8, thereby achieving precise control of the wire conveying speed. At the same time, the driving mechanism is also equipped with a torque sensor, which can monitor the change in resistance during the calibration process in real time and provide a feedback control signal for the calibration process.

[0052] The control component is the control core of the entire device, and the control module uses a PLC control system. This system comprehensively monitors and adjusts the operating state of the device by collecting data from the torque sensor in the driving component, the pressure sensor in the calibration component, and the position sensor during the wire conveying process. The control component can automatically adjust the pressure of the calibration roller 4, the position of the support roller 3, and the conveying speed of the spring wire 5 according to the preset calibration parameters and the actual state of the spring wire 5, realizing intelligent calibration control.

[0053] The detection component is used to conduct quality detection on the spring wire 5. This mechanism includes a laser rangefinder 9 and an image module 10. The laser rangefinder 9 can accurately measure the diameter and straightness of the spring wire 5, and the image module 10 takes the surface image of the wire through a high-speed camera and uses image processing algorithms to detect defects and shape deviations on the wire surface. The detection component feeds back the detection results to the control component in real time for targeted adjustment during the calibration process.

[0054] Specific implementation steps of this embodiment:

[0055] 1). Equipment preparation and debugging

[0056] Equipment inspection: Before starting the device, conduct a comprehensive inspection of the device to ensure that all components are working properly. The inspection contents include whether the installation of the support roller 3 and the calibration roller 4 is firm, whether the variable-frequency motor 7 is normal, and whether the sensors are correctly connected, etc.

[0057] Parameter setting: Set the calibration parameters, including the pressure of the calibration roller 4, the position of the support roller 3, and the conveying speed of the spring wire 5.

[0058] Equipment debugging: Start the drive component to make the support roller 3 and the calibration roller 4 rotate idly, check whether the equipment runs smoothly, and whether there are abnormal sounds or vibrations. Ensure that the equipment is in a normal working state by checking whether the sensor signals are normal.

[0059] 2). Steel wire installation and initial calibration

[0060] Steel wire installation: Pass the spring steel wire 5 to be calibrated through between the two support rollers 3 in the support component, ensure that the spring steel wire is smoothly conveyed between the support rollers 3, and adjust the position and spacing of the support rollers 3 according to the diameter of the spring steel wire 5 to keep the spring steel wire 5 stable during the conveying process.

[0061] Initial calibration: Start the drive component to make the spring steel wire 5 start to be conveyed under the action of the support roller 3 and the calibration roller 4. In the initial calibration stage, the control component automatically adjusts the pressure of the calibration roller 4 and the position of the support roller 3 according to the preset parameters to perform preliminary calibration on the spring steel wire 5. At this time, the pressure applied by the calibration roller 4 to the spring steel wire 5 is relatively small, and the main purpose is to make the spring steel wire gradually adapt to the correction device to avoid wire deformation caused by excessive pressure.

[0062] 3). Multi-stage calibration and real-time monitoring

[0063] Multi-stage calibration: After the spring steel wire 5 passes through the initial calibration, it enters multiple calibration units in the calibration component. The calibration roller 4 of each calibration unit applies different pressures to the steel wire to gradually eliminate the bending and twisting of the steel wire. The control component adjusts the pressure of the calibration roller 4 and the position of the support roller 3 in real time according to the sensor data collected to ensure the stability and accuracy of the calibration process.

[0064] Real-time monitoring: During the multi-stage calibration process, the control component comprehensively monitors the calibration process by collecting the signals of the torque sensor, pressure sensor and position sensor. If abnormal conditions are detected, such as a sudden increase in resistance or abnormal calibration roller pressure, the control component will automatically adjust the calibration parameters to ensure the smooth progress of the calibration process.

[0065] 4). Quality inspection and feedback adjustment

[0066] Quality inspection: The calibrated steel wire enters the detection component. The laser rangefinder 9 accurately measures the diameter and straightness of the steel wire. The image module 10 takes pictures of the surface image of the steel wire through a high-speed camera and uses image processing algorithms to detect defects and shape deviations on the surface of the steel wire. The detection results are fed back to the control mechanism in real time.

[0067] Feedback adjustment: The control component optimizes and adjusts the correction process according to the detection results. If it is detected that the straightness or surface quality of the steel wire does not meet the preset standards, the control component will automatically adjust the pressure of the correction roller 4, the position of the support roller 3, or the conveying speed of the steel wire for targeted correction until the quality of the steel wire meets the requirements.

[0068] 5) Completion of correction and equipment shutdown

[0069] Completion of correction: When the detection component confirms that both the straightness and surface quality of the steel wire meet the preset standards, the correction process is completed. At this time, the control mechanism sends a signal to stop the operation of the drive mechanism, and the steel wire correction is completed.

[0070] Equipment shutdown: After the correction is completed, the equipment is shut down. The drive component is turned off, and the rotation of the support roller 3 and the correction roller 4 is stopped.

Therefore, the appended claims are intended to be construed as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
