The glass fiber forming is a crucial link in the whole glass fiber product production process, and the bushing plate is a key component in the production process. In the whole production period, the structure of the bushing plate can deform to generate deviation due to the change of temperature difference of glass liquid, environment and the like. If the glass fiber is continuously used for production in such a situation, the difference between products obtained by splitting can be caused, and the linear density, the yarn group tension and other properties of the glass fiber products can be seriously influenced.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The calibration device provided according to the present invention will be described in detail below with reference to the accompanying drawings.

The utility model provides a calibrating device which is used for calibrating a cooler of a bushing in fiber production. Fig. 1 shows a schematic structural diagram of a specific embodiment of the calibration device of the present invention, and referring to fig. 1, the calibration device includes a frame 1 and at least one set of calibration mechanisms 2 spaced apart from the frame 1, and each set of calibration mechanisms 2 can be calibrated for one cooler in one operation. Illustratively, in a production line of glass fiber, the cooler of the bushing is divided into three parts, and three groups of calibration mechanisms 2 can be arranged on the frame 1 at intervals, so as to simultaneously calibrate the three parts of coolers, thereby improving the calibration efficiency and ensuring the normal operation of glass fiber production. For example, the tooth mouth inclination directions and angles of the three parts of the cooler are different, and three sets of the calibration mechanisms 2 can be respectively arranged for the tooth mouth structures of the cooler at corresponding positions.

The main body of the frame 1 can be made of metal, the whole set of calibration device is fixed on the ground, and the whole set of calibration device does not displace with the ground in the calibration process, so that the calibration precision is guaranteed.

Fig. 2 shows a schematic structural diagram of the alignment mechanism 2 in an embodiment of the present disclosure, and referring to fig. 1 and fig. 2 together, the alignment mechanism 2 includes a bottom mold 21, a calibration mold 22, a driver 23, and a positioning assembly 24. The bottom die 21 and the driver 23 are both fixed on the frame 1, the calibration die 22 is located above the bottom die 21 and is fixedly connected with the output end of the driver 23, and the driver 23 drives the calibration die 22 to reciprocate towards the bottom die 21. The cooler to be calibrated is placed on the bottom die 21, then the driver 23 drives the correction die 22 to press downwards, and the cooler is calibrated by utilizing the impact force of the downward pressing of the correction die 22 and the support of the bottom die 21.

The positioning assembly 24 is fixedly connected to the frame 1 to position the cooler, so as to prevent the position of the cooler from shifting during the pressing process of the calibration die 22 and affecting the calibration effect.

In an alternative embodiment, the positioning assembly 24 is arranged flush with the bottom die 21 and is used to define the position between the cooler and the bottom die 21, ensuring the positional stability between the cooler and the bottom die 21 during the pressing down of the correcting die 22, and thus ensuring the accuracy of the alignment of the cooler.

In an alternative embodiment, the positioning assembly 24 comprises a fixing rail 241, a push rod 242 and a linkage locking structure 243, wherein the fixing rail 241 is fixed on the frame 1, the extending direction of the rail 241 is set towards the bottom mold 21, the push rod 242 is slidably connected with the fixing rail 241, and the height of the push rod 242 on the fixing rail 241 is set to be equal to the height of the cooler placed on the bottom mold 21. One end of the linkage locking structure 243 is rotatably connected with the fixed track 241 or the frame 1, the other end of the linkage locking structure 243 is in transmission connection with the push rod 242, the push rod 242 can be driven to slide along the fixed track 241 by adjusting the linkage locking structure 243, and the push rod 242 is fixed at a certain position on the fixed track 241, so that the position limitation of the cooler is realized.

Illustratively, the linkage locking structure 243 can adopt a multi-link structure, and includes an operating handle 244, and the operating handle 244 can be used to push the linkage locking structure 243 to drive the push rod 242 to move on the fixed track 241, and limit the push rod 242, so as to realize the positioning and releasing of the cooler.

As the cooler calibration needs stronger pressure, SKD11 material with higher hardness and yield strength is used as the material type of the bottom die 21 and the correction die 22 of the calibration mechanism 2, the strength is greater than the yield strength of the copper sheets of the cooler, the distance between the cooler sheets and the angle position of each sheet can be better adjusted, and the standardization of accurate calibration is achieved.

In order to further ensure the calibration precision of the cooler, the position of the cooler sheet is calibrated by adopting a mode that the driver 23 drives the correction die 22 to punch downwards. In the actual calibration process, for the calibration of one cooler, the driver 23 may be used to drive the calibration die 23 to perform reciprocating punching downward at least once, for example, three times, so as to ensure the calibration accuracy.

In an alternative embodiment, the actuator 23 is a hydraulic actuator. Illustratively, the actuator 23 may comprise a linear reciprocating hydraulic cylinder. In this embodiment, the actuator 23 is in a top-up mode in order to ensure that pressure stabilization is provided and that cooler calibration quality is guaranteed.

In order to improve the calibration accuracy and the uniformity of the calibration strength, the operating parameters of the driver 23, such as the number of operations and the operating power, need to be controlled. In an optional embodiment, the calibration mechanism 2 further includes a controller 25, the controller 25 is electrically connected to the driver 23, and the controller 25 is used to control start-stop and operation parameters of the driver 23, so as to ensure that the strength and accuracy of each calibration are consistent, and also can be adjusted according to calibration requirements of coolers of different production lines.

In an alternative embodiment, the calibration mechanism 2 further comprises a sensor 26 in signal communication with the controller 25 for sensing whether the cooler is in place. When the sensor 26 senses that the cooler is placed in place, a signal is sent to the controller 25, and the controller 25 receives the signal and controls the driver 23 to start up, so that automatic control of the calibration process is realized.

In another alternative embodiment, the sensor 26 is not used to sense the signal of the cooler, but rather is used to sense other object signals within the press range, such as a human body or other tool. When the sensor 26 senses that an object is blocked in the stamping range, the sensor sends a signal to the controller 25, and the controller 25 controls the driver 23 to stop running so as to avoid safety accidents. Illustratively, the sensor 26 may be a photoelectric sensor.

The above-described aspects may be implemented individually or in various combinations, and such variations are within the scope of the present invention.
