Embodiment Construction

[0054] like Figure 1 to Figure 11 As shown, it is a manufacturing process of a dumbbell-shaped member with a gradual change in section height of the present invention, comprising the following steps:

[0055] A manufacturing process for a dumbbell-shaped component with a gradual change in section height, comprising the following steps:

[0056] (1) Processing of arc semi-circular tubes:

[0057] a. Process a straight round tube according to the design size, cut the straight round tube in half to obtain a straight half round tube, and mechanically cut the welding groove on the straight half round tube by cutting equipment; directly cut the straight round tube in half to obtain a straight half round tube. Semi-circular pipe, and mechanically cut the welding groove on the straight semi-circular pipe, which can effectively ensure the precision of the cut groove, and the use of mechanical cutting processing can ensure cutting efficiency and cutting quality, reduce labor intensity...

Abstract

The invention discloses a manufacturing process of a dumbbell-shaped component with gradually-changed section height. The manufacturing process comprises the following steps: (1) processing an arc-shaped semicircular pipe; (2) machining a welding backing and a web steel plate; (3) welding and fixing the welding lining plate and the arc-shaped semicircular pipe; and 4) welding and fixing the arc-shaped semicircular pipe and the web steel plate. According to the machining method, the welding groove is machined in the straight semicircular pipe firstly, machining is convenient and automatic, the semicircular pipe with the machined welding groove is subjected to segmented bending machining, and the semicircular pipe is machined into the arc-shaped semicircular pipe finally meeting the requirement step by step through segmented multi-time micro-bending machining; the product performance and quality of the finally formed arc-shaped semicircular pipe are effectively ensured, the semicircular pipe is limited and fixed through the fixed clamping frame in the actual machining process, the flame heating device conducts high-temperature heating on the to-be-bent section, the yield strength of the semicircular pipe is reduced, and the movable clamping frame assists in supporting and limiting the semicircular pipe; and then the semicircular pipe is stretched by moving the clamping frame in cooperation with radial tension until micro-bending is completed.

Description

technical field [0001] The invention belongs to the technical field of processing a Y-shaped member formed by group welding of a steel plate and an arc-shaped semi-circular tube, and particularly relates to a manufacturing process of a dumbbell-shaped member whose cross-section height changes. Background technique [0002] Dumbbell-shaped components are favored by construction engineers because of their beautiful shapes, and are used more and more. Such components are composed of semicircular tubes as main limbs, steel plates as webs, and curved semicircular tubes are combined with steel plates by welding. In the prior art, after the semi-circular tube is bent and formed, a welding cutout needs to be processed according to requirements. According to the current processing technology, the welding slit cannot be mechanically processed, and manual flame cutting is required. Manual flame cutting cannot guarantee the groove precision and the groove processing speed. SUMMARY O...
