Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling design technology, and in particular to automated control and detection for bar finishing lines, including material feeding, deceleration position, full material position, and counting. Background Technology
[0002] In the bar production of steel rolling mills, the finishing processes such as shot blasting, straightening, chamfering, flaw detection, and peeling and grinding all suffer from problems such as high pace, large vibration, and significant dust impact. Online chamfering and other finishing processes also involve high temperatures, resulting in unstable automated detection signals (easily lost, long-term signals, failure to reset or jamming, intermittent signals, etc.). Detection elements and mounting brackets are prone to loosening, deformation, and damage leading to failure, resulting in short lifespans, high safety risks from false signals, high maintenance difficulty, and poor reliability of automated production. This severely restricts the production efficiency of bar finishing lines. In conjunction with the improvement of automated bar finishing line technology, and through continuous research on the production operations and automatic detection control of bar finishing lines, a highly reliable detection element bracket has been developed for automated control detection of material presence, deceleration position, full material position, and counting on bar finishing lines. This effectively meets the automated detection requirements and production needs of bar finishing lines. Utility Model Content
[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a high-reliability detection element bracket for bar finishing lines. This can solve the problems of short lifespan, such as easy loosening, deformation and damage leading to failure of detection elements and mounting brackets, high safety risks of false signals, high maintenance difficulty, poor reliability of automated production, and serious constraints on the production efficiency of bar finishing lines.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-reliability testing element bracket for a bar finishing line, comprising a support square steel and a testing device; the surface of the support square steel is welded with a first support lug and a second support lug; the testing device comprises a swing arm, a pin, a self-lubricating bushing, bolts, spring washers, flat washers, a pressure cap, screws, a counterweight plate, and nuts. Before welding, the distance between the first support lug and the second support lug is adjusted to be greater than the thickness of the swing arm. The counterweight plate is installed on the swing arm by bolts, spring washers, flat washers, screws, and nuts.
[0005] Preferably, the self-lubricating bushing is installed in the inner hole of the swing arm.
[0006] Preferably, the swing arm is mounted in the self-lubricating bushings of the first and second support lugs via a pin, and the swing arm can rotate around the pin.
[0007] Preferably, the pressure cap secures the detection element to the first and second support lugs using bolts, spring washers, and flat washers.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] 1. The bar finishing line uses a high-reliability detection element bracket. The bracket structure and the installation method of the detection element have been optimized. The bracket structure is more robust, less prone to deformation and damage, and has a longer service life. The detection element is fixed with bolt caps, which is not easy to loosen and the signal is more stable.
[0010] 2. This bar finishing line uses a high-reliability detection element bracket with minimal axial movement of the swing arm, which improves the stability of the input signal. The structural design of the swing arm and the ear seat effectively controls the gap between them, preventing axial oscillation caused by swing arm gap changes, which could lead to signal loss or intermittent signal issues. Self-lubricating bushings are used in the rotating parts of the sensing swing arm, effectively avoiding signal non-reset and long-term erroneous signals caused by swing arm rotation jamming, thus greatly improving the reliability of the bracket.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a high-reliability detection element bracket for a bar finishing line, including a support square steel 4 and a detection device. The surface of the support square steel 4 is welded with a first support ear 5 and a second support ear 6. The detection device includes a swing arm 1, a pin 2, a self-lubricating bushing 3, a bolt 7, a spring washer 8, a flat washer 9, a pressure cap 10, a screw 11, a counterweight plate 12, and a nut 13. Before welding, the distance between the first support ear 5 and the second support ear 6 is adjusted to be greater than the thickness of the swing arm 1. The counterweight plate 12 is installed on the swing arm 1 by bolts 7, spring washers 8, flat washers 9, screws 11, and nuts 13. The self-lubricating bushing 3 is installed in the inner hole of the swing arm 1. The swing arm 1 is installed in the self-lubricating bushing of the first support ear 5 and the second support ear 6 by pin 2. The swing arm 1 can rotate around the pin 2. The pressure cap 10 fixes the detection element on the first support ear 5 and the second support ear 6 by bolts 7, spring washers 8, and flat washers 9.
[0022] When using this detection element bracket, the operator first determines and fixes the bracket according to the specific requirements of the site. When the detection device is not in operation, the swing arm 1 hangs down under gravity and falls to the position of the detection element mounting hole. Figure 3 As shown; when the bar reaches the detection position, the swing arm 1 contacts the bar and rotates around the pin 2. At this time, the relative position of the swing arm 1 and the detection element (the mounting position of the round hole of the pressure cap 10) changes. When the swing arm 1 rotates to the position where it is disengaged from the sensing position of the detection element (e.g., Figure 4As shown, the detection element senses a change in the input signal and obtains the incoming material signal. When the bar stock leaves the detection position, the swing arm 1 rotates around the pin 2 to its original position under the action of gravity. The detection element senses that the swing arm 1 has returned to its original position and outputs a no-material signal, ready to detect the next incoming material. Compared with traditional detection elements, this detection bracket has optimized the bracket structure and the installation method of the detection element. The mounting bracket structure is more robust, less prone to deformation and damage, and has a longer service life. The detection element is fixed by bolts 7 and caps 10, which is not easy to loosen and the signal is more stable.
[0023] The small axial movement of the swing arm 1 is beneficial to improving the stability of the input signal. The structural design of the swing arm 1 and the ear seat allows for effective control of the gap between them, preventing axial oscillation caused by changes in the gap of the swing arm 1, which could lead to signal loss or intermittent signal. The use of a self-lubricating bushing 2 in the rotating part of the sensing swing arm 1 effectively avoids signal non-reset and long-term erroneous signals caused by the rotation of the swing arm 1, thus greatly improving the reliability of the bracket.
[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
