[0003] Main existing problems: During the quenching process of the wear-resistant steel bars, there are phenomena such as bending and jamming of the steel bars, resulting in the abnormal operation of the wear-resistant steel bars and causing quenching at both ends of the steel bars (the production requirement is that the positions 10 cm at both ends of the wear-resistant steel bars are not quenched). The steel bars quenched at both ends need to be picked out separately. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a temperature measuring and sorting device for wear-resistant steel bars, which solves the problem of how to detect and sort the temperatures at both ends of the finished steel bars.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

Specific implementation mode

[0029] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the attached drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0030] As Figure 1 Shown in the top view of the wear-resistant steel bar temperature measurement and sorting device, it includes a transfer roller path 1, a temperature measurement component 2, a qualified steel bar storage rack 3, and a scrap steel bar storage rack 4.

[0031] The temperature measurement component 2 is used to detect the temperatures of the front and rear ends of the steel bar 10 on the transfer roller path 1. If the front and rear ends are not quenched, the temperature value is relatively high, and it is a qualified product, which is stored on the qualified steel bar storage rack 3. If the front and rear ends are quenched, the temperature value is relatively low, and it is an unqualified product, which is stored on the scrap steel bar storage rack 4. Since the qualified steel bar storage rack 3 and the scrap steel bar storage rack 4 are arranged on both sides of the transfer roller path 1, the qualified and unqualified steel bars 10 are placed separately, so the steel bars 10 are placed in an orderly manner and are not easily damaged.

[0032] The temperature measurement component 2 includes a first temperature measurement probe 21 and a second temperature measurement probe 22. Define Figure 1The right front is the front, and the left is the back. The first temperature measuring probe 21 is arranged at the front end of the conveying roller path 1, and the second temperature measuring probe 22 is arranged at the back end of the conveying roller path 1. The steel bar 10 is placed on the conveying roller path 1. The front end of the steel bar 10 corresponds to the first temperature measuring probe 21 and is measured by the first temperature measuring probe 21; the back end of the steel bar 10 corresponds to the second temperature measuring probe 22 and is measured by the second temperature measuring probe 22. The temperatures of the front and back ends of the steel bar 10 are obtained by the first temperature measuring probe 21 and the second temperature measuring probe 22 respectively. Since the wear-resistant steel bar requires no quenching within 10 mm at both ends, under normal production conditions, the temperatures at both ends are much higher than the temperature in the middle, and the temperatures at both ends are about 600 °C; however, due to the bending and malfunction of the blank during the quenching process, the two ends of the steel bar are quenched, and the temperatures at the two ends of the steel bar are relatively low, between 220 °C and 230 °C. Therefore, it is possible to judge whether the two ends of the steel bar have experienced quenching according to the temperature values at the two ends of the steel bar.

[0033] As Figure 1 and Figure 2 , a striker 7 is arranged on the front side of the conveying roller path. The striker 7 is used to stop and position the steel bar 10. A buffer structure can also be arranged in the striker 7 so that there is a buffer when the steel bar 10 is stopped. The striker 7 can accurately stop the front end of the steel bar 10 at the position of the first temperature measuring probe 21.

[0034] Figure 2 As shown, there are two first temperature measuring probes 21, which are distributed on both sides of the steel bar 10 and are aligned with an area of about 10 cm at the front end 101 of the steel bar 10. Two detection values can be obtained, and the two detection values can be compared or averaged to improve the accuracy of temperature detection. The two first temperature measuring probes 21 can also be staggered in the front-back direction by a first set distance, so as to detect the temperatures at different axial positions of the front end 101 of the steel bar, increasing the sampling points and improving the reliability of the detection values. At least one first temperature measuring probe 21 can be arranged.

[0035] As Figure 3 shown, two second temperature measuring probes 22 are arranged corresponding to the back end 102 of the steel bar 10. The two second temperature measuring probes 22 are distributed on both sides of the conveying roller path 1 and are aligned with the back end 102 of the steel bar 10 for measuring the temperature of the back end 102 of the steel bar. The two second temperature measuring probes 22 can also be staggered in the front-back direction by a second set distance. The second set distance can be equal to or different from the aforementioned first set distance.

[0036] The second temperature measuring probe 22 is connected to the probe position adjusting rod 23. The probe position adjusting rod 23 is arranged on the side of the conveying roller path 1. The extending direction of the probe position adjusting rod 23 is the same as the extending direction of the conveying roller path 1 and is also the same as the length direction of the steel bar 10 on the conveying roller path 1. The second temperature measuring probe 22 can change its position on the probe position adjusting rod 23. In this way, the temperature measurement operation can be carried out on steel bars 10 with different lengths.

[0037] AsFigure 1 On both sides of the transfer roller path 1, a qualified steel bar storage rack 3 and a scrap steel bar storage rack 4 are respectively arranged. A qualified steel bar turning mechanism 5 is arranged between the qualified steel bar storage rack 3 and the transfer roller path 1, and is used for turning the qualified steel bars 10 on the transfer roller path 1 onto the qualified steel bar storage rack 3. A scrap steel bar turning mechanism 6 is arranged between the scrap steel bar storage rack 4 and the transfer roller path 1, and is used for turning the unqualified steel bars 10 on the transfer roller path 1 onto the scrap steel bar storage rack 4.

[0038] As Figure 4 , the qualified steel bar turning mechanism 5 includes a first turning cylinder 51, a first lever 52, and a first rotating shaft rod 53. The driving end of the first turning cylinder 51 is connected to the first rotating shaft rod 53 (or a connecting rod is arranged below the first rotating shaft rod 53, and the driving end of the first turning cylinder 51 is connected to the lower end of the connecting rod). The first turning cylinder 51 can drive the first rotating shaft rod 53 to rotate along the axis of the first rotating shaft rod 53 itself. The first lever 52 is connected to the first rotating shaft rod 53. When the first rotating shaft rod 53 rotates along the axis of the first rotating shaft rod 53 itself, the first lever 52 can swing around the axis of the first rotating shaft rod 53. The first lever 52 extends into the gap between two adjacent transfer rollers 11, and the initial position is below the steel bar 10. When the first lever 52 swings upward, it lifts the steel bar 10 and turns the steel bar 10 onto Figure 1 the first tabletop 31 as shown.

[0039] As Figure 1 , a plurality of first levers 52 are arranged and distributed in the length direction of the first rotating shaft rod 53. The extending direction of the first rotating shaft rod 53 is the same as the extending direction of the transfer roller path 1 and also the same as the length direction of the steel bar 10. Using a plurality of first levers 52 to lift the steel bar 10 at multiple points can prevent the steel bar 10 from deforming when being transferred.

[0040] The first lever 52 can also be directly driven by the first turning cylinder 51 without passing through the first rotating shaft rod 53. The first rotating shaft rod 53 can drive a plurality of first levers 52 to rotate simultaneously, improving the efficiency.

[0041] The first tabletop 31 is composed of a plurality of inclined rods arranged in parallel in the length direction of the transfer roller path 1. The inclined direction of the first tabletop 31 gradually decreases from the end close to the transfer roller path 1 to the far end, that is Figure 1 gradually decreases in the direction from top to bottom in Figure 1is a top view and cannot show the height), which prompts the steel bar 10 to roll downward on the first tabletop 31. At the lower end of the first tabletop 31, that is, the lower height position, there is a first stop 32. The first stop 32 blocks the downward rolling of the steel bar 10 and keeps the steel bar 10 on the first tabletop 31. There are multiple first stops 32, all connected to the stop shaft rod 9, so as to block the steel bar 10 at multiple points. The stop shaft rod 9 is also rotatably arranged and connected to the driving end of the stop rotating cylinder 8 (or a connecting rod is arranged below the stop shaft rod 9, and the driving end of the stop rotating cylinder 8 is connected to the lower end of the connecting rod), and can be driven to rotate by the stop rotating cylinder 8. When the stop shaft rod 9 rotates, it drives the first stop 32 to swing. The first stop 32 can swing to a position where it loses the blocking effect on the steel bar 10, and the qualified steel bar 10 is discharged from the far side of the first tabletop 31.

[0042] As Figure 1 , the scrap steel bar turning mechanism 6 and the qualified steel bar turning mechanism 5 are arranged based on the same principle, including a second turning cylinder 61, a second lever 62, and a second rotating shaft rod 63.

[0043] The driving end of the second turning cylinder 61 is connected to the second rotating shaft rod 63 (or a connecting rod is arranged below the second rotating shaft rod 63, and the driving end of the second turning cylinder 61 is connected to the lower end of the connecting rod). The second turning cylinder 61 can drive the second rotating shaft rod 63 to rotate along the axis of the second rotating shaft rod 63 itself. The second lever 62 is connected to the second rotating shaft rod 63. When the second rotating shaft rod 63 rotates along the axis of the second rotating shaft rod 63 itself, the second lever 62 can swing around the axis of the second rotating shaft rod 63. The second lever 62 extends into the gap between two adjacent transmission rollers 11 and is initially located below the steel bar 10. When the second lever 62 swings upward, it lifts the steel bar 10 and flips the steel bar 10 to Figure 1 the second tabletop 41 shown in

[0044] As Figure 1 , there are multiple second levers 62, which are distributed in the length direction of the second rotating shaft rod 63. The extending direction of the second rotating shaft rod 63 is the same as the extending direction of the transmission roller path 1 and also the same as the length direction of the steel bar 10. Using multiple second levers 62 to lift the steel bar 10 at multiple points can prevent the steel bar 10 from deforming when being transferred.

[0045] The second lever 62 can also be directly driven by the second turning cylinder 61.

[0046] The second tabletop 41 is composed of multiple inclined rods arranged in parallel in the length direction of the transmission roller path 1. The inclination direction of the second tabletop 41 gradually decreases from the end close to the transmission roller path 1 to the far end, that is Figure 1 gradually decreases in the direction from bottom to top in Figure 1(The top view cannot show the height), which prompts the steel bar 10 to roll downward on the second tabletop 41. At the upper end of the second tabletop 41, that is, the lower height position, a second stop 42 is provided. The second stop 42 blocks the continuous downward rolling of the steel bar 10 and holds the steel bar 10 on the second tabletop 41. A plurality of second stops 42 are provided to block the steel bar 10 at multiple points. Since the second tabletop 41 is used to collect unqualified steel bars 10 and the number of steel bars 10 is not large, the second stop 42 can be made non-swingable. Of course, the second stop 42 can also be set to be swingable like the first stop 32.

[0047] In summary, the wear-resistant steel bar temperature measurement and sorting device in this example can measure the temperatures of the front end and the rear end of the steel bar 10, and decide whether to activate the qualified steel bar turning mechanism 5 or the scrap steel bar turning mechanism 6 according to the temperature measurement results. The qualified steel bar turning mechanism 5 turns the qualified steel bars 10 to the qualified steel bar storage rack 3 for storage, and the scrap steel bar turning mechanism 6 turns the unqualified steel bars 10 to the scrap steel bar storage rack 4 for storage. The steel bars 10 are sorted orderly, which is conducive to the subsequent packing operation.

The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly.
