[0002] Steel cord production involves multiple processes including rough drawing, medium drawing, electroplating, wet drawing, and stranding. The rough and medium drawing of steel wire requires the use of drawing dies, and the quality of the drawing surface of the die directly affects the surface quality of the steel wire after drawing. The surface quality of the steel wire will affect the wire breakage rate of the finished cord product. Therefore, the control of the drawing die is particularly important.

[0003] At present, the inspection of drawing dies all uses a microscope. The microscope is used to magnify the drawing surface inside the drawing die. The main purpose is to observe whether the compression area and sizing area of ​​the drawing surface have scratches, cracks, etc., and to judge whether the drawing die meets the production requirements. However, when observing with a microscope, there is currently no corresponding fixture that can support the drawing die. As a result, the drawing die is mostly fixed by hand when observed under a microscope. The position and angle of the drawing die are difficult to adjust accurately. In addition, the drawing die is difficult to keep stable during observation, and the operation is relatively laborious, resulting in the inability to guarantee the accuracy of observation and inspection.

[0024] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0025] When using a microscope to observe the drawing die, there is no corresponding fixture to support the drawing die, resulting in the drawing die mostly being fixed by hand when observed under a microscope. The position and angle of the drawing die are difficult to adjust accurately, and the drawing die is difficult to keep stable during observation. The operation is relatively laborious, resulting in the inability to guarantee the observation and detection accuracy.

[0026] Combine Figure 1-Figure 3 As shown, the utility model provides a cord drawing die optical detection support, comprising a movable seat 1 and a fixed base 2, wherein the fixed base 2 can carry the movable seat 1;

[0027] A first light hole 102 is provided through the center of the movable seat 1, and a step hole 101 for fixing the drawing die is provided at the top of the first light hole 102. A second light hole 201 is provided through the center of the fixed base 2. When the movable seat 1 is placed on the fixed base 2, the step hole 101, the first light hole 102 and the second light hole 201 are in a coaxial position and are interconnected. The reflector of the microscope can transmit light from the first light hole 102 and the second light hole 201 to the step hole 101, providing a light source for the drawing die installed in the step hole 101.

[0028] In an optional embodiment, the material of the fixed base 2 is plastic, which can reduce the overall weight of the support.

[0029] Combine Figure 2 As shown, the movable seat 1 is configured as a hemispherical structure, and the top surface of the second light-through hole 201 is provided with a curved surface 202 corresponding to the outer shape of the movable seat 1. When the bottom of the movable seat 1 is set in the curved surface 202, the movable seat 1 can rotate axially in the curved surface 202 and can also be tilted to adjust the angle. It has high flexibility and can fully inspect the inside of the drawing die.

[0030] In this way, during inspection, the fixed base 2 is first placed on the stage of the microscope and fixed, and then the drawing die is installed in the step hole 101 of the movable seat 1. The drawing die is stably supported by the fixed base 2 and the movable seat 1, and then the drawing die is rotated and the tilt angle is adjusted by the movable seat 1 to fully inspect the inside of the drawing die. Compared with hand-held adjustment, the use of support adjustment can make the drawing die more stable and improve the observation and detection accuracy.

[0031] Furthermore, a plurality of magnets 21 capable of generating magnetic attraction to the movable seat 1 are embedded and fixed around the inner wall of the curved surface 202, and the movable seat 1 is correspondingly configured to be made of a magnetic material that can be magnetically attracted. When the movable seat 1 is movable and adjusted within the curved surface 202, the magnetic attraction force is utilized to enable the movable seat 1 to be magnetically fixed when adjusted to any position, thereby maintaining the current position and angle, facilitating observation by personnel, and further improving the stability of observation and detection.

[0032] In a preferred embodiment, the magnet 21 is configured as a neodymium iron boron magnet, which has a strong magnetic force. A relatively small number of neodymium iron boron magnets can be used to complete the magnetic fixation of the movable seat 1 .

[0033] In a specific embodiment, the side surface of the magnet 21 located on the arc surface 202 is set to be an arc surface with the same curvature as the arc surface 202 and does not protrude from the surface of the arc surface 202, maintaining the smoothness of the arc surface 202 and avoiding interference with the movement of the movable seat 1.

[0034] Furthermore, a lubricating layer 103 capable of reducing friction is provided on the outer side surface of the movable seat 1 , thereby reducing wear between the movable seat 1 and the arc-shaped surface 202 .

[0035] In a preferred embodiment, the lubricating layer 103 is a polytetrafluoroethylene coating. The friction coefficient of polytetrafluoroethylene is extremely low, which can play a role in lubrication and reducing wear.

[0036] Drawing dies of different sizes only have changes in diameter, and no changes in shape.

[0037] Combine Figure 3 As shown, the stepped hole 101 is configured as a multi-level stepped hole with different diameters, which can adapt to the installation of drawing dies of various sizes and improve applicability.

[0038] Furthermore, the depth of each step hole 101 is 3.0-5.0 mm, preferably 5.0 mm, so that the drawing die can be inserted into the step hole 101 for a longer distance, which can maintain the stability of the drawing die installation and prevent the drawing die from falling during the detection and adjustment process.

[0039] Combine Figure 3 As shown, the inner diameter of the second light hole 201 is larger than the inner diameter of the first light hole 102, so that when the step hole 101 is tilted, light can pass through the second light hole 201 and enter the first light hole 102, maintaining the light required for observation and detection of the drawing die.

[0040] Combine Figure 1 As shown, the fixed base 2 is provided with two mutually symmetrical fixing grooves 203 for clamp fixing, and the pressing plate on the microscope stage can be pressed and fixed to the fixed base 2 through the fixing grooves 203.

[0041] In combination with the above embodiments, a movable seat 1 and a fixed base 2 capable of supporting the movable seat 1 are provided, and the movable seat 1 is provided with a stepped hole 101 for fixing the drawing die. At the same time, the movable seat 1 is configured to be able to rotate axially on the fixed base 2, and can also be tilted to adjust the angle. It has high flexibility and can fully inspect the inside of the drawing die. Compared with hand-held adjustment, the use of support adjustment can make the drawing die more stable and improve the observation and detection accuracy.

[0042] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
