[Prior art]
在目前使用的現代桿軋機中’熱軋桿成品由最後的軋 機座被送出，且藉通過一或更多的水箱加以冷卻。該等桿 成品隨後藉剪機分割成桿區段’該剪機包括用以將該等桿 區段交替的引導至通向冷卻床的兩下游輸送路徑的任一路 徑的轉轍器。夾緊滾輪單元、摩擦墊及其他類似物可使沿 輸送路徑行進的桿區段減速’因此’桿區段可在橫向移轉 至冷卻床上之前，逐漸滑移而完全停止。In the modern rod rolling mills currently used, the 'hot-rolled rod finished products are sent out from the final rolling stand and cooled by passing through one or more water tanks. The rod finished products are then divided into rod sections by a shearing machine. The shearing machine includes a switch for alternately guiding the rod sections to either of the two downstream conveying paths to the cooling bed. The clamping of the roller unit, the friction pad, and the like can slow down the rod section traveling along the conveying path ', so that the rod section can be gradually slipped and stopped completely before being laterally moved to the cooling bed.
當乳機滾乳較大尺寸的成品’例如直徑大於1 〇 · 0至 1 2.0 mm的成品時，此種配置可獲得相當大的總噸數。這 些較大成品在以相當高的軋機輸送速度下（】『3 Q米/秒 )被推動通過水箱時，因具有足夠的柱強度而可承受彎曲 變开多。 然而，當成品尺寸減小時，柱強度也降低，故軋機輸 送速度必須減慢，以避免當推動較小尺寸成品通過水箱時 而彎曲變形。 因此，例如，單一滾軋8 . 〇 ni m桿以輸送至舖設頭的 絞軋機可在6 0米/秒或大於6 0米/秒的輸送速度下作業 ，而得8 5噸/小時的產量。 -4- (2) 1244949 然而’相同的滾軋8 · 0 mm桿以輸送至冷卻床的絞軋 機卻需在顯著減緩的輸送速度，約3 2米/秒下作業，而 僅得4 5噸/小時的產量。桿成品輸送速度的減慢主要原 因是習知的桿處理系統無法在較快速移動成品在橫向移轉 至冷卻床上之前將其等停住。 本發明一目的爲提升軋機可滾軋桿成品的噸位定額， 尤其是滾軋較小尺寸成品，例如直徑小於1 2.0 mm者。 本發明另一目的是提升自軋機輸送較小桿成品的速度 ，然後在該等成品藉水箱冷卻前，及被輸送至冷卻床之前 使其等減速。 【發明內容】 依據本發明，熱軋桿成品被剪機分割成桿區段，而該 等桿區段被交替的引導至兩下游中間路徑的任一路徑。在 各中間路徑上的一轉轍器隨後將桿區段交替的導引至兩通 向冷卻床的下游輸送路徑的任一路徑。將沿四條輸送路徑 行進的桿區段加以減速’最好是以至少兩階段行之。第一 減速階段的作甩是使得桿區段減慢抵一中級速度，此中級 速度比桿成品自軋機送出的速度爲慢，而第二減速階段的 作用是進一步使桿區段減慢抵一適於將桿成品輸送至冷卻 床的較低速度。桿區段在以中級速度行進的同時，在第一 及第二減速階段之間被冷卻。 【實施方式】 ~ 5 - (3) 1244949 首先參考圖1及圖2A_C，顯示依據本發明的一系統 位於連續性桿熱軋機之最後滾軋台1 〇及習知冷卻床1 2之 間。自滾軋台1 0沿路徑PA送出的桿成品通過一系列水箱 1 4，之後藉一分割剪機1 6再分割成桿區段。剪機1 6可以 是精於本技藝之人士所熟知的設計，其包含可將該等經細 分的桿區段交替的引導至兩下游中間路徑Pb、Pc的任一 路徑的轉轍機構。在中間路徑P B上的一轉轍器1 8可交替 的將該等桿區段引導至兩下游輸送路徑]?0、？£的任一路 徑’而在中間路徑Pc上的一轉轍器20同樣交替的將成品 區段引導至兩下游輸送路徑P F、p G的任一路徑。並側配 置的輸送路徑組P D、P E及P F、P G經一系列水箱2 2通向 夾緊滾輪單元24、26，而後環繞部分由兩相對成18〇。的 線C】、C2所界定的側環。曲線c 1 一部份是由一可移除 的導引邰分2 8構成。側运包括水箱3 0，且在曲線c 2處 ，雨組輸送路徑組P D、P e及P F、P g在繼續前進至位於冷 卻床】2之前的夾緊滾輪單元3 2、3 4前變成垂直對齊。 參考圖3，可知具有相互側向間隔開之導引管4 〇的 層疊單一導引單元3 6、3 8被採用以沿側向配置且垂直向 偏位的輸送路彳空組P D、p E及P F、P G引導桿區段，且當該 兩組輸送路徑組相垂直對齊時，兩層疊槽單元4 2被採用 以導引該等桿區段。 如0 4及5所不’夾緊浪輪單兀3 2具有兩組分別與 輸送路徑PF及PG相互對齊的夾緊滾輪44、46，且夾緊滾 輪單兀3 4也具有兩組分別與輸送路徑p 〇及p £相互對齊 -6- 52、 1244949 (4) 的夾緊滾輪48、5〇。各組夾緊滾輪獨立的藉驅動軸 齒輪箱5 4及驅動馬達5 6驅動之。夾緊滾輪係以選定 度被驅動，以適當使以摩擦方式被夾持於其等之間的 段減速。 夾緊滾輪單元2 4、2 6以相同方式構製，但在配 面稍有不同，以與側向配置且垂直向交錯配置的導引 相對齊。 現利用在6 0米/秒的相當高速及約9 5 〇 _丨〇 5 〇。〇 下自最後滾乳台1 〇輸送至冷卻床的8.0 m m直徑桿成 一範例以進一步敘述上述系統的作業。關閉水箱！ 4 許桿成品自由通過抵剪機1 6，桿成品在此被細分成 的桿區段。剪機的轉轍機構將該等桿區段交替的引導 間路徑PB、Pc。在路徑PB上行進的桿區段隨後藉由 器】8交替的引導至輸送路徑p D、P E，而在路徑p c 進的桿區段藉由轉轍器20以相同方式交替的引導至 路徑PF 、 PG 。 之後，夾緊滾輪單元24、26做動以首先使得桿 減慢抵約30米/秒的較低中級速度。桿區段由彎曲 引部分28所導引而環繞該側環及通過水箱30。夾緊 單元24、26及水箱30之間的線性距離最好是小於桿 的長度。因此，桿區段以有利的減緩速度進入水箱 且同時是受夾緊滾輪單元24、2 6的作用下。水箱3 0 區段通過曲線C2前加以冷卻至約5 00-600 °C。夾緊滾 元3 2、3 4隨後進一步使得桿區段減速抵約3 - 8米/ 的速 桿區 置方 路徑 溫度 品當 以允 連續 至中 轉轍 上行 輸送 區段 的導 滾輪 區段 30， 在桿 輪單 秒的 1244949 (5) 速度，而使得桿區段可在冷卻床1 2之進入端處完全停止 。由此處，移轉機構（未示）將桿區段橫向的移轉至及冷 卻床上，桿區段在抵達冷卻床的輸送側前在此處受到進一 步的冷卻。 本發明的一特點是爲自分割剪機16送出的連續桿區 段設置的複數輸送路徑，其中該分割剪機1 6與供通過轉 轍器1 8、20的成品使用的複數輸送路徑相連接。在上述 範例中，連續桿區段將重複的受下列次序所支配。 中間路徑 輸送路徑When the milking machine rolls a larger-sized finished product, for example, a finished product having a diameter larger than 1.0 to 1 2.0 mm, this configuration can obtain a considerable total tonnage. When these larger finished products are pushed through the water tank at a relatively high rolling mill conveying speed (] [3 Q m / s), they can withstand bending and opening due to sufficient column strength. However, when the size of the finished product is reduced, the column strength is also reduced, so the rolling mill conveying speed must be slowed down to avoid bending and deformation when pushing the smaller size finished product through the water tank. Therefore, for example, a single stranding mill that rolls a 8.0 mm rod to the laying head can operate at a conveying speed of 60 m / s or more, resulting in an output of 85 tons / hour. . -4- (2) 1244949 However the 'same rolling mill that rolls 8 · 0 mm rods to the cooling bed needs to operate at a significantly slower conveying speed, about 32 meters per second, and only 45 tons Output per hour. The main reason for the slowdown of the finished rod conveying speed is that conventional rod processing systems cannot stop the faster moving finished products before they are laterally transferred to the cooling bed. An object of the present invention is to improve the tonnage quota of the finished product of the rollable rod of the rolling mill, especially for rolling smaller-sized finished products, such as those with a diameter less than 1 2.0 mm. Another object of the present invention is to increase the speed of conveying smaller rod products from the rolling mill, and then decelerate these products before they are cooled by the water tank and before being transported to the cooling bed. [Summary of the Invention] According to the present invention, a finished hot-rolled rod is divided into rod sections by a shearing machine, and the equal rod sections are alternately guided to any one of two downstream intermediate paths. A switch on each intermediate path then alternately guides the rod section to either of the two downstream conveying paths to the cooling bed. Deceleration of the rod section traveling along the four conveying paths is preferably performed in at least two stages. The first deceleration phase is to slow down the rod section to an intermediate speed. This intermediate speed is slower than the speed of the rod finished product sent from the rolling mill, and the second deceleration phase is to further slow the rod section by one. Lower speed suitable for conveying finished rods to a cooling bed. The rod segment is cooled between the first and second deceleration phases while traveling at an intermediate speed. [Embodiment] ~ 5-(3) 1244949 First, referring to FIGS. 1 and 2A-C, it is shown that a system according to the present invention is located between the last rolling stand 10 and the conventional cooling bed 12 of the continuous rod hot rolling mill. The finished rod sent from the rolling table 10 along the path PA passes through a series of water tanks 14 and then is divided into rod sections by a cutting shear 16. The shear 16 may be a design well known to those skilled in the art, and it includes a switch mechanism that can alternately guide the divided rod sections to any one of the two downstream intermediate paths Pb, Pc. A switch 18 on the intermediate path P B can alternately guide the equal rod section to the two downstream conveying paths]? 0,? Any path of £ 'and a switch 20 on the intermediate path Pc also alternately guides the finished product section to any of the two downstream conveying paths P F, p G. The parallel-set conveying path groups P D, P E, and P F, P G pass through a series of water tanks 22 to the clamping roller units 24, 26, and the surrounding portions are formed by two opposing ones. The side ring defined by line C] and C2. The part of the curve c 1 is composed of a removable guide element 28. The side transport includes the water tank 3 0, and at the curve c 2, the rain group transport path groups PD, Pe, and PF, Pg continue to advance to the clamping roller unit 3 2, 3, 4 before the rain group 2 becomes Align vertically. Referring to FIG. 3, it can be seen that a stacked single guide unit 3 6, 3, 8 having laterally spaced guide tubes 4 0 is adopted to transport the air gap groups PD, p E in a laterally arranged and vertically offset position. And PF and PG guide rod sections, and when the two sets of conveying path groups are aligned vertically, two stacked groove units 42 are adopted to guide the rod sections. As shown in 0 4 and 5, the clamping roller unit 3 2 has two sets of clamping rollers 44 and 46 respectively aligned with the conveying paths PF and PG, and the clamping roller unit 34 also has two groups of The conveying paths p 0 and p £ are aligned with the clamping rollers 48, 50 of -6-52, 1244949 (4). Each group of clamping rollers is independently driven by the driving shaft gear box 5 4 and the driving motor 56. The clamping rollers are driven at a selected degree to appropriately decelerate the segments held between them in a frictional manner. The clamping roller units 2 4 and 2 6 are constructed in the same manner, but are slightly different in alignment to align with the guides arranged sideways and vertically staggered. A fairly high speed at about 60 meters per second and about 95 ° _ 丨 〇 5 〇 are now utilized. An example of the 8.0 mm diameter rod conveyed to the cooling bed from the last milking table 10 is given below to further describe the operation of the above system. Close the water tank! 4 The finished rod is allowed to pass freely through the shearing machine 16. The finished rod is here subdivided into rod sections. The switch mechanism of the shears alternates the inter-guide paths PB, Pc of the equal rod sections. The rod section traveling on the path PB is then guided alternately to the conveying path p D, PE by the device], and the rod section advancing on the path pc is alternately guided to the path PF by the switch 20 in the same manner. , PG. Thereafter, the clamping roller units 24, 26 act to first slow the lever down to a lower intermediate speed of about 30 m / s. The rod section is guided by the curved guide portion 28 to surround the side ring and pass through the water tank 30. The linear distance between the clamping units 24, 26 and the water tank 30 is preferably smaller than the length of the rod. Therefore, the rod section enters the water tank at a favorable slowing speed and is simultaneously under the action of the clamped roller units 24, 26. Section 3 of the water tank is cooled to approximately 500-600 ° C before passing through curve C2. The clamping rollers 3 2, 3 4 then further decelerate the rod section to a temperature of approximately 3-8 meters per square path of the speed rod zone. The guide roller section 30 is allowed to continue to the intermediate point upward conveying section. At a speed of 1244949 (5) per second for the rod wheel, the rod section can be completely stopped at the entry end of the cooling bed 12. From here, the transfer mechanism (not shown) laterally transfers the rod section to the cooling bed, where the rod section is further cooled before reaching the conveying side of the cooling bed. A feature of the present invention is a plurality of conveying paths provided for the continuous rod sections sent from the splitting shears 16, wherein the splitting shears 16 are connected to a plurality of conveying paths for finished products passing through the switches 18, 20. . In the above example, the continuous bar section will be repeatedly dominated by the following sequence. Intermediate path

As shown in Fig. 6, when processing a larger rod and a slower rod, the system reorganizes the curved guide portion 28 by a straight, tapered guide portion 58. This omits formation at 180 ° from each other. The side ring between the curved parts C 1 and C 2. In this operating mode, the enhanced column strength of the larger diameter finished product and the lower conveying speed of the rolling mill allow cooling to take place in the water tank 22. Therefore, a two-stage deceleration will occur, first performed by the clamping roller units 24, 26, and then by -8-1244949 (6) clamping roller units 3, 34. It can be seen that the system of the present invention is extremely flexible, as it can accommodate a wide range of finished products with high tonnage quotas. Finished products with smaller diameters, such as those between 6.35 and 1 2.0 mm, can pass freely through the water tank 22 at a high conveying speed of 60 to 32 meters per second, and use clamping before cooling in the water tank 30 The roller units 24, 26 perform initial deceleration to handle this. Large diameter finished products with a diameter greater than 12.0 mm and delivered from the rolling mill at a lower speed of less than 30 meters per second can be cooled in the water tank 22 before the initial deceleration by the clamping roller units 24, 26. . As shown in Fig. 7, the two systems of the type disclosed in Fig. 1 can be arranged side by side to correspond to the same cooling bed.
