Abstract

An U-shaped bifurcated pipe integral-forming process includes the steps of: (1) heating a blank in a medium-frequency furnace to 850-1200 degrees centigrade, (2) forging the blank after medium-frequency heating to a Y-shaped bar by Y-shaped forging dies, (3) drilling the Y-shaped bar to form a Y-shaped inner channel by a drilling device, (4) bending the V-shaped head of the Y-shaped bar to U shape to form the U-shaped bifurcated pipe. The present invention utilizes the die forging and extruding technology to form the U-shaped bifurcated pipe, so that the pressure resistance of the U-shaped bifurcated pipe is far excessive to that of the welded bifurcated pipe, and the production cost is low.

Description

分叉管的 休成型工  Folding tube
木領域  Wood field
本 涉及分叉管制各 木領域 尤其涉及 U 分叉管的 休 成型工 。 背景 木  This is related to the fork control of various wood fields, especially the U-shaped forks. Background
在 沒有 休制造 木 U 分叉 內外制造此 焊接 且在 上注明"焊接不宜" 因U型分叉 在 中的工作 。  This welding is made inside and outside the manufacturing U-fork and the "welding is not suitable" due to the work of the U-branch.
高溫高 溫度大于400 C 大于 16 Mpa 所以焊接 有 多 因素的 、 焊接 力集 容易造成 二、 焊接力人工操作 手工保 所以 相 大 三、 拍片、 高 要求高 氫 打底再用 休 成本 高 且形成內向 至少降低20% 通 在 制造 是至 重要的 介 木 而直接 休 由于 不能 至 底部 所以拍片 合形成 有 假象  High temperature and high temperature greater than 400 C is greater than 16 Mpa. Therefore, welding has many factors, and the welding force set is easy to cause. 2. The welding force is manually operated by hand. Therefore, the film is large, the film is required, the high hydrogen base is used again, and the cost is high and the inward direction is formed. At least 20% reduction in manufacturing is the most important thing, and the direct rest is due to the inability to reach the bottom.
很大雅 。 上 在U 分叉 焊接上 直是 介 不 費工、 、 不 而且 、 很高。  Very elegant. On the U-fork welding, it is straightforward, not expensive, and very high.
內容 本 力克服現有 木的不足 中 加熱 休成型工 各 神不易爆裂、 的U 分叉 。 Content The force overcomes the shortcomings of the existing wood, and the U-fork which is not easy to burst, is heated by the molding workers.
上 目的 本 的 U 分叉管的 休成型工 其特 在于 如下加工步驟 將 好的料加熱至850 120 C 2 第一 休成型 將中 的料 The U-fork tube of the above purpose is characterized by the following processing steps: heating the good material to 850 120 C 2
3 內 成型 將  3 Inner molding will
各 內通道 4 成型 再將 的 U 形成U 狀分叉 。  Each inner channel 4 is formed and the U is formed into a U-shaped bifurcation.
的加工步驟 中 加熱完成 至 成型完成的60 90  Processing steps in the heating finish to 60 90
本 現有 木相比 、 木 U 分叉 休 成型 性能近近 焊接分叉 不易爆裂 且制造成本只 有焊接 的50 60 因 所以不必 同 。  Compared with the existing wood, the wood U bifurcation is close to the welding, the welding fork is not easy to burst, and the manufacturing cost is only 50 60 because of welding, so it is not necessary.
是 焊接 的U 分叉管的 示意Is the indication of the welded U-furcation tube
2是本 明中U 分叉管的 示意 。  2 is an illustration of the U-furcation tube in the present invention.
