Abstract

The invention relates to a U-shaped heating furnace tube bending machining process. Furnace tube bending equipment is adopted by the process 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...
