Description

Technical Field

[0001] This utility model relates to the technical field of copper tube billet defect detection, and in particular to a device for detecting defects in horizontal continuous casting copper tube billets. Background Technology

[0002] In the continuous casting production of copper and copper alloy tubes, horizontal continuous casting technology is widely used due to its advantages of high efficiency and continuous production. However, during the solidification process, copper tube billets are prone to defects such as surface cracks, inclusions, and porosity due to fluctuations in process parameters or abnormal equipment conditions. If these defects are not detected in time during production, they will directly affect the yield and quality of subsequent processing. Traditional inspection methods mostly rely on manual sampling or offline inspection, which suffers from low inspection efficiency, high missed detection rate, and poor real-time performance, making it difficult to meet the high standards of quality control required by modern continuous casting production lines.

[0003] However, the automation level of existing automated testing equipment is insufficient. Traditional equipment mostly uses manual or semi-automatic loading and unloading methods, which are labor-intensive and prone to deviations in tube blank positioning due to operational errors, affecting the testing accuracy. When tube blanks are stacked, friction or jamming can easily cause interruptions in the material supply, requiring frequent manual intervention and restricting the production cycle. The lack of efficient connection between loading and unloading actions and the testing process results in low overall equipment efficiency. Utility Model Content

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Reference Figures 1-7 This embodiment provides equipment for defect detection in horizontally continuously cast copper tube billets, including:

[0037] The main support frame 1 is supported on the ground, and the testing housing 11 is mounted on the main support frame 1.

[0038] Automatic loading and unloading mechanism 2 is set at the top of the main support 1 and inside the detection housing 11;

[0039] The testing mechanism 3 is located on the top of the testing housing 11 and is used to test the tube blank;

[0040] The automatic loading and unloading mechanism 2 includes:

[0041] The storage rack 21 is fixedly installed on the main support 1. Multiple feeding plates 22 are arranged crosswise on the storage rack 21, and the adjacent feeding plates 22 correspond to each other.

[0042] A tube blank support frame 23 is fixedly installed on the main support frame 1. A tube placement groove is provided on the top of the tube blank support frame 23, and a partition strip 24 is provided on the side of the tube blank support frame 23. The partition strip 24 is in contact with the lowest set of feeding plates 22. Two sliding grooves 25 are provided on the tube blank support frame 23.

[0043] The pusher cylinder 26 is fixedly installed on the tube blank support frame 23;

[0044] The lifting plate 27 is slidably mounted on the tube blank support frame 23 and is driven to slide up and down by the pushing cylinder 26. The lifting plate 27 is provided with two feeding blocks 28 and two discharging blocks 29. The two feeding blocks 28 are located on the outside of the partition bar 24 and are used to lift the tube blank to be tested on the feeding plate 22. The two discharging blocks 29 are located on the inside of the partition bar 24 and are slidably mounted in the two slide grooves 25 to lift the tube blank in the conveying tube groove.

[0045] In this embodiment, copper tube blanks are horizontally stacked on the cross-feeding plates 22 of the storage rack 21. Adjacent feeding plates 22 form a stepped structure, and the tube blanks naturally roll down to the contact point between the bottom feeding plate 22 and the spacer 24 by gravity. The design of the spacer 24 and the bottom feeding plate 22 prevents the tube blanks from accidentally slipping down, and at the same time limits the stacking height of the tube blanks by friction to avoid jamming. The pushing cylinder 26 drives the lifting plate 27 to slide upward, and the loading support block 28 is inserted from the outside of the spacer 24 between the bottom feeding plate 22 and the tube blank, lifting the tube blank to be tested and detaching it from the feeding plate 22. The lifting plate 27 continues to rise, sending the tube blank into the tube placement groove at the top of the tube blank support frame 23, completing the precise positioning. After the group of tube blanks is pushed up, the loading support block 28 moves down. After resetting, the tube blanks on the feeding plate 22 will automatically roll to the spacer 24, completing the automatic replenishment of the tube blanks; the detection mechanism 3 performs non-contact scanning on the tube blanks in the tube slot, collecting surface and internal defect data in real time; after the detection is completed, the pusher cylinder 26 drives the lifting plate 27 to descend, and the unloading support block 29 lifts the tube blank and slides it out of the tube slot, pushing the tube blank out of the tube slot at the top of the tube blank support frame 23; after the lifting plate 27 resets, the next set of tube blanks automatically enters the detection station, realizing continuous cycle operation; through the cross feeding plate 22 of the storage rack 21 and the double support block collaborative mechanism of the lifting plate 27, manual or semi-automatic loading and unloading are replaced, significantly reducing labor costs; the loading support block 28 and the unloading support block 29 are arranged in sections and driven by the same cylinder to realize "picking up - The integrated "inspection-feeding" action simplifies the mechanical structure and improves the coordination of actions; the feeding plates 22 with cross-shaped storage racks 21 use geometric structure to realize automatic layered falling of tube blanks without the need for additional power devices, reducing energy consumption and improving the stability of material supply; the number of tube blanks conveyed is precisely controlled by mechanical limiters to avoid multiple tubes entering the inspection area at the same time, ensuring the uniqueness and accuracy of the inspection station.

[0046] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, the top of both the feeding support block 28 and the unloading support block 29 are set with inclined guide surfaces. The inclined guide surface of the feeding support block 28 faces the side of the unloading support block 29, and the inclined guide surface of the unloading support block 29 is in the direction away from the feeding support block 28.

[0047] In this embodiment, when the pushing cylinder 26 drives the lifting plate 27 to rise, the inclined guide surface of the feeding support block 28 faces the unloading support block 29. When the inclined guide surface contacts the tube blank, its tilt angle can guide the tube blank to roll smoothly down the inclined surface into the tube placement groove, avoiding tube blank jamming or displacement due to horizontal friction. After the inspection is completed, the lifting plate 27 descends, and the inclined guide surface of the unloading support block 29 lifts the tube blank and slides it out of the tube placement groove. The reverse tilt design of the inclined guide surface allows the tube blank to roll naturally down the inclined surface to the sorting area when it leaves the tube placement groove, reducing the damage to the surface of the tube blank caused by the vertical falling impact. The back-facing design of the inclined guide surface can be seamlessly connected with the conveying track of the sorting mechanism, allowing the tube blank to slide to the qualified or defective product area along a preset path, avoiding manual intervention.

[0048] Specifically, such as Figure 1 As shown, a transfer plate 2a is provided on the main support 1. The transfer plate 2a is used to receive the tube blank after testing, which is supported by the feeding support block 29. An output plate 2b is provided on the main support 1. The output plate 2b is used to receive the tube blank output by the transfer plate 2a and to transport the tube blank to the outside of the equipment.

[0049] In this embodiment, after the test is completed, the pusher cylinder 26 drives the lifting plate 27 to descend, and the unloading support block 29 lifts the tube blank and slides it out of the tube placement groove; the inclined guide surface of the unloading support block 29 causes the tube blank to roll down the inclined surface to the surface of the transfer plate 2a; the transfer plate 2a transports the tube blank to the output plate 2b, and the output plate 2b further transports the tube blank to the outside of the equipment; the transfer plate and the output plate achieve fully automatic transfer through a mechanical structure, reducing manual intervention and labor intensity; the tube blank after the test can be immediately received and transported by the transfer plate, which is synchronized with the test process, avoiding the tube blank from staying at the test station and improving the overall efficiency of the equipment.

[0050] More specifically, such as Figure 6 As shown, testing organization 3 includes:

[0051] The lifting cylinder 31 is fixedly installed on the top of the testing machine housing 11;

[0052] The testing frame 32 is installed inside the testing machine housing 11 and is driven to move up and down by the lifting cylinder 31.

[0053] A sliding plate 33 is horizontally mounted on a detection frame 32, and a detector 34 is mounted on the sliding plate 33.

[0054] The screw 35 is rotatably mounted in the detection frame 32. The screw 35 is driven by a motor and is threadedly engaged with the slide plate 33 to drive the slide plate 33 to slide.

[0055] In this embodiment, the lifting cylinder 31 is in a retracted state, the detection frame 32 is located at the top of the detection housing 11, and the detector 34 is far away from the tube blank. After the automatic loading and unloading mechanism 2 transports the tube blank to the tube placement slot, the lifting cylinder 31 extends and drives the detection frame 32 to descend vertically, bringing the detector 34 closer to the surface of the tube blank. According to the diameter of the tube blank or the detection requirements, the lifting cylinder 31 can adjust the height of the detection frame 32 in real time to ensure that the detector 34 maintains a constant distance from the surface of the tube blank, adapting to the tube blank detection. After the detection frame 32 is in place, the motor drives the screw 35 to rotate, which drives the slide plate 33 to slide horizontally through the threaded engagement. The slide plate 33 slides at a constant speed, and the detector 34 completes a full surface scan along the axial direction of the tube blank, which can improve the detection accuracy and coverage, and improve the detection efficiency and real-time performance.

[0056] Furthermore, such as Figure 6 As shown, two guide posts 36 are symmetrically arranged on the testing frame 32, and both guide posts 36 are slidably inserted into the top of the testing housing 11;

[0057] In this embodiment, the guiding function of the guide post 36 can control the deviation of the lifting trajectory of the inspection frame 32, ensure the accuracy of the distance between the inspection instrument 34 and the surface of the tube blank, and avoid the distortion of the inspection signal caused by the distance fluctuation; the vertical lifting of the inspection frame 32 ensures that the scanning plane of the inspection instrument 34 is always perpendicular to the axis of the tube blank, thereby improving the measurement accuracy of surface defects.

[0058] Furthermore, such as Figure 7 As shown, a positioning cylinder 12 is provided on the side of the main support 1, a transmission plate 13 is provided at the output end of the positioning cylinder 12, and a tube blank push plate 14 is provided on the transmission plate 13. The tube blank push plate 14 is used to position and adjust the tube blank in the tube blank placement groove of the tube blank support frame 23.

[0059] In this embodiment, when the automatic loading and unloading mechanism 2 lifts the tube blank to be tested into the tube slot of the tube blank support frame 23, the tube blank may be axially or radially offset due to stacking, transportation or gravity. The piston rod of the positioning cylinder 12 extends and pushes the transmission plate 13 to move along the tube blank axis, driving the tube blank push plate 14 to move synchronously. The tube blank push plate 14 contacts the end of the tube blank and pushes the tube blank to the designated center position of the tube slot, ensuring that the tube blank axis is perpendicular to the scanning plane of the detection mechanism 3. The combined design of the positioning cylinder 12, the transmission plate 13 and the tube blank push plate 14 significantly improves the accuracy and efficiency of tube blank positioning, solves the problems of large error and low efficiency of traditional manual positioning, and can improve detection accuracy.

[0060] Furthermore, a protective rubber pad is adhered to the side end face of the billet pusher plate 14;

[0061] In this embodiment, the soft material of the protective pad avoids rigid contact between the tube blank pusher plate 14 and the tube blank, reducing defects such as scratches and indentations on the tube blank surface caused by collision or friction, and improving the surface quality of the tube blank. For thin-walled copper and copper alloy tube blanks, it can prevent tube blank deformation or cracking caused by excessive positioning pressure. As a buffer layer, the protective pad reduces direct friction between the tube blank pusher plate 14 and the tube blank, reduces the wear rate of the pusher plate, and extends the service life of the equipment. Due to the protective effect of the protective pad, the downtime for equipment maintenance caused by damage to the tube blank surface is reduced, and maintenance costs are lowered.

[0062] Furthermore, such as Figure 7 As shown, two guide rods 15 are symmetrically arranged on the transmission plate 13, and both guide rods 15 are slidably inserted into the side end of the detection housing 11.

[0063] In this embodiment, the sliding engagement of the guide rod 15 ensures the linear movement trajectory of the transmission plate 13 and the billet pusher plate 14, avoiding positioning errors caused by offset or rotation. The guiding effect of the guide rod 15 makes the pushing force of the billet pusher plate 14 on the billet more uniform and stable, improving the positioning accuracy. The sliding engagement of the guide rod 15 reduces the vibration and impact during the driving process of the positioning cylinder 12, making the entire positioning adjustment process smoother. By reducing mechanical wear caused by offset or rotation, the guiding effect of the guide rod 15 extends the service life of key components such as the transmission plate 13 and the positioning cylinder 12.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
