Embodiment Construction
[0029] Attached below Figure 1-3 The present invention will be described in detail.
[0030] A U-shaped heating furnace tube bending process using a clamp position sensing sensor and performing stress relief heat treatment, 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. passageway through; on the guide rod 15, three bending hydraulic devices 9 are sequentially slid between the left frame 13 and the pu...

The invention discloses a U-shaped furnace tube bending process adopting a clamp position sensor and carrying out stress relief annealing. According to the U-shaped heating furnace tube bending machining process, furnace tube bending equipment is adopted and comprises a left rack and a pushing and pressing mechanism, the pushing and pressing mechanism is arranged on the right side of the left rack, a guide rod is fixedly arranged in the middle of the right side of the left rack, the guide rod horizontally extends in the left-and-right direction, the left end of the guide rod is fixedly connected with the left rack, the right end of the guide rod is in sliding connection with the middle of the pushing and pressing mechanism, and a channel which allows an original fed U-shaped furnace tube to pass and allows a discharged machined furnace tube to pass is arranged in the left rack. Three bending hydraulic devices are sequentially arranged at the position, between the left rack 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...
