To address this, we designed an aperture detection device for tungsten carbide wire drawing dies to provide an alternative technical solution to the above-mentioned technical problems.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-6 A hole diameter detection device for tungsten steel wire drawing die includes a V-shaped support frame 1, an L-shaped base plate 2 at one end of the V-shaped support frame 1, a movable transverse sliding plate 7 at the top of the L-shaped base plate 2, an H-shaped lifting frame 10 at the top of the transverse sliding plate 7, a rotatable circular rotating box 12 inside the H-shaped lifting frame 10, a transverse detection needle 6 at one end of the circular rotating box 12, and an industrial camera at one end and on the surface of the transverse detection needle 6.

[0025] The outer side of the H-shaped lifting frame 10 is provided with a rotating mechanism for rotating the circular rotating box 12;

[0026] The top of the V-shaped support frame 1 is provided with a V-shaped clamping plate 3, and both ends of the V-shaped support frame 1 are provided with a first hydraulic cylinder 4. The output end of the first hydraulic cylinder 4 is fixedly connected to the V-shaped clamping plate 3. Through the setting of the first hydraulic cylinder 4, the V-shaped clamping plate 3 can be vertically raised and lowered, thereby fixing the wire drawing die between the V-shaped support frame 1 and the V-shaped clamping plate 3 to prevent the wire drawing die from displacement during testing.

[0027] One end of the L-shaped base plate 2 is bolted with a first drive motor 5. The output end of the first drive motor 5 is fixed with a transverse threaded rod 8. The transverse threaded rod 8 passes through the interior of the transverse sliding plate 7 and is threadedly connected to the transverse sliding plate 7. Through the operation of the first drive motor 5, the transverse threaded rod 8 can rotate, thereby enabling the transverse sliding plate 7 to move laterally inside the L-shaped base plate 2.

[0028] Both sides of the L-shaped base plate 2 are fixed with transverse light rods 9. The transverse light rods 9 pass through the interior of the transverse sliding plate 7 and are slidably connected to the transverse sliding plate 7, so that the transverse sliding plate 7 can slide laterally on the outside of the transverse threaded rod 8, thereby guiding the movement trajectory of the transverse sliding plate 7.

[0029] Here, the operation of the first drive motor 5 enables the transverse threaded rod 8 to rotate. The rotation of the transverse threaded rod 8 enables the transverse sliding plate 7 to move laterally outside the transverse light rod 9, thereby enabling the circular rotating box 12 to move toward the V-shaped support frame 1, and thus enabling the transverse detection needle 6 to enter the interior of the wire drawing die.

[0030] The rotating mechanism includes a third hydraulic cylinder 14. The third hydraulic cylinder 14 is fixed on the outside of the H-shaped lifting frame 10. The output end of the third hydraulic cylinder 14 is rotatably connected to a longitudinal connecting column 15 through a bearing. The outside of the longitudinal connecting column 15 is rotatably connected to an oblique transmission column 16 through a bearing. The top of the oblique transmission column 16 is rotatably connected to an oblique rotating column 17 through a pin. The inside of the top of the oblique rotating column 17 is fixed to a longitudinal rotating column 18. The longitudinal rotating column 18 passes through the inside of the H-shaped lifting frame 10 and is rotatably connected to the H-shaped lifting frame 10 through a bearing. The longitudinal rotating column 18 is located on the side close to the circular rotating box 12 and is fixedly connected to the circular rotating box 12.

[0031] A dovetail slider is fixed at one end of the longitudinal connecting column 15 near the H-shaped lifting frame 10. A vertical dovetail groove is provided inside the H-shaped lifting frame 10. The longitudinal connecting column 15 and the circular rotating ring 19 are slidably connected by the cooperation of the dovetail slider and the vertical dovetail groove. Through the cooperation of the dovetail slider and the vertical dovetail groove, the longitudinal connecting column 15 can slide vertically on the outside of the H-shaped lifting frame 10.

[0032] Both ends of the transverse sliding plate 7 are fixed with a second hydraulic cylinder 13. The output end of the second hydraulic cylinder 13 is fixedly connected to the H-shaped lifting frame 10. Through the operation of the second hydraulic cylinder 13, the H-shaped lifting frame 10 can slide vertically on the outside of the transverse sliding plate 7, thereby adjusting the position and height of the transverse detection needle 6 to adapt to the height of different radial positions of the wire drawing die.

[0033] A second drive motor 11 is bolted to one end of the circular rotating box 12 away from the transverse detection needle 6. The output end of the second drive motor 11 is fixedly connected to the transverse detection needle 6. A circular rotating ring 19 is provided outside the transverse detection needle 6 and inside the circular rotating box 12. A T-shaped rotating ring 20 is rotatably connected inside the circular rotating ring 19 via a bearing. The T-shaped rotating ring 20 is located inside the circular rotating box 12 and is fixedly connected to the circular rotating box 12. Through the rotatable connection between the T-shaped rotating ring 20 and the circular rotating ring 19, the transverse detection needle 6 can rotate inside the circular rotating box 12. When the circular rotating box 12 rotates, the transverse detection needle 6 can rotate.

[0034] Here, when the inner diameter of the wire drawing die is smaller than the diameter of the transverse detection needle 6, the operation of the third hydraulic cylinder 14 enables the longitudinal connecting column 15 to be vertically raised and lowered. The raising and lowering of the longitudinal connecting column 15, through the oblique transmission column 16 and the oblique rotating column 17, enables the longitudinal rotating column 18 to rotate inside the H-shaped lifting frame 10. The rotation of the longitudinal rotating column 18 enables the circular rotating box 12 to rotate inside the H-shaped lifting frame 10, thereby enabling the transverse detection needle 6 to rotate around the radial direction of the longitudinal rotating column 18. Through the operation of the second drive motor 11, the transverse detection needle 6 can rotate inside the circular rotating box 12, so that the industrial camera at one end of the transverse detection needle 6 can observe the internal aperture of the wire drawing die.

[0035] When the inner diameter of the wire drawing die is larger than the diameter of the transverse detection needle 6, the transverse detection needle 6 can enter the interior of the wire drawing die, so that the industrial camera on the top of the transverse detection needle 6 can detect the internal aperture of the wire drawing die. Through the operation of the second drive motor 11, the transverse detection needle 6 can rotate around the radial direction of the transverse detection needle 6 to facilitate the detection of the wire drawing die space.

[0036] Through a series of designs, the large-diameter wire drawing die adopts a transverse detection needle 6 for active detection, while the small-diameter wire drawing die adopts an inclined non-contact detection, which significantly improves the equipment's adaptability to wire drawing dies of different sizes. The non-contact optical measurement avoids mechanical damage to the inner wall of the die hole caused by traditional probes. By having the transverse detection needle 6 enter the interior of the wire drawing die and rotate, complete three-dimensional data of the inlet, middle and outlet of the wire drawing die hole can be obtained, enabling a comprehensive assessment of the wear condition.

[0037] Working principle: The operation of the first drive motor 5 enables the transverse threaded rod 8 to rotate. The rotation of the transverse threaded rod 8 enables the transverse sliding plate 7 to move laterally outside the transverse light rod 9, thereby enabling the circular rotating box 12 to move towards the V-shaped support frame 1, and thus enabling the transverse detection needle 6 to enter the interior of the wire drawing die.

[0038] When the inner diameter of the wire drawing die is smaller than the diameter of the transverse detection needle 6, the operation of the third hydraulic cylinder 14 enables the longitudinal connecting column 15 to be vertically raised and lowered. The raising and lowering of the longitudinal connecting column 15, through the inclined transmission column 16 and the inclined rotating column 17, enables the longitudinal rotating column 18 to rotate inside the H-shaped lifting frame 10. The rotation of the longitudinal rotating column 18 enables the circular rotating box 12 to rotate inside the H-shaped lifting frame 10, thereby enabling the transverse detection needle 6 to rotate around the radial direction of the longitudinal rotating column 18. Through the operation of the second drive motor 11, the transverse detection needle 6 can rotate inside the circular rotating box 12, so that the industrial camera at one end of the transverse detection needle 6 can observe the internal aperture of the wire drawing die.

[0039] When the inner diameter of the wire drawing die is larger than the diameter of the transverse detection needle 6, the transverse detection needle 6 can enter the interior of the wire drawing die, so that the industrial camera on the top of the transverse detection needle 6 can detect the internal aperture of the wire drawing die. Through the operation of the second drive motor 11, the transverse detection needle 6 can rotate around the radial direction of the transverse detection needle 6 to facilitate the detection of the wire drawing die space.
