Abstract

Disclosed is a bending technology for a furnace tube of a linear heating furnace. According to the heating technology of the furnace tube of the linear heating furnace, furnace tube bending equipment is adopted and comprises a left frame (13) and a pushing and pressing mechanism (10). The pushing and pressing mechanism (10) is arranged on the right of the left frame (13), a dovetail guide rail (15) is fixedly connected on the rear portion of the right side of the left frame (13) and extends in left and right directions horizontally, the left end of the dovetail guide rail (15) is fixedly connected with the left frame (13) while the right end of the same is slidably connected with a dovetail groove in the rear portion of the pushing and pressing mechanism (10), a through hole allowing the furnace tube to penetrate through is formed in the front portion of the left frame (13), and three bent hydraulic devices (9) are sequentially slidably arranged from left to right between the left frame (13) and the pushing and pressing mechanism (10).

Description

[0001] technical field [0002] This application relates to the manufacture of heating furnace tubes, specifically a straight-line heating furnace tube bending process. [0003] Background technique [0004] 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. [0005] 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...
