Embodiment Construction

[0031] Attached below Figure 1-5 The present invention will be described in detail.

[0032] A U-shaped heating furnace tube bending process for performing stress-relieving heat treatment and ejecting and removing materials, which uses a furnace tube bending device. The U-shaped furnace tube bending device includes a left frame 13 and a pushing mechanism 10, and the pushing Mechanism 10 is on the right side of left frame 13, and guide rod 15 is fixedly arranged at the middle position on the right side of said left frame 13. Guide rod 15 extends horizontally in the left-right direction. The frame 13 is fixedly connected, and the right end of the guide rod 15 is slidably connected with the middle part of the pushing mechanism 10. The left frame 13 is provided with the original U-shaped furnace tube loading and unloading for the completed process. Passing channel 101; on the guide rod 15, three bending hydraulic devices 9 are slidingly arranged in sequence from left to right be...

Abstract

The invention provides a bending technology for U-shaped heating furnace tubes. According to the bending technology, a furnace tube bending device is applied. The furnace tube bending device comprises a left machine frame and a pushing and pressing mechanism, wherein the pushing and pressing mechanism is located on the right side of the left machine frame, a guide rod is fixedly arranged at the middle position of the right side of the left machine frame, the guide rod horizontally extends leftwards and rightwards, the left end of the guide rod is fixedly connected with the left machine frame, and the right end of the guide rod is connected with the middle portion of the pushing and pressing mechanism in a sliding mode. A channel is arranged in the left machine frame, and the channel is used for feeding and penetrating of original U-shaped furnace tubes and discharging of the machined furnace tubes. Three bending hydraulic devices are sequentially arranged on the portion, between the left machine frame and the pushing and pressing mechanism, of the guide rod from left to right in a sliding mode.

Description

technical field [0001] This application relates to the manufacture of heating furnace tubes, specifically a U-shaped heating furnace tube bending process. Background technique [0002] Heating furnaces are widely used in industry, such as billet heating, workpiece heat treatment, etc. In order to increase the heating uniformity of the heating furnace, the furnace tube is often bent. [0003] In the prior art, in order to ensure the requirements for the specific shape of the heating furnace and meet the respective requirements for the specific heating heat, it is usually necessary to bend the shape of the furnace tube in a specific shape. For the bending of the furnace tube of the heating furnace, stamping is often used in the prior art. This forming method can efficiently and quickly realize bending processing, has high processing precision and low cost, and is widely used in the prior art. However, this heating method is easy to produce a large amount of uneven deformati...
