Forming device and method of mesh-shaped steel framework

Abstract

The invention discloses a forming device of a mesh-shaped steel framework. The forming device comprises a machine frame, a rotary frame, a weft pay-off spool and a wire spool. A mandrel is inserted in the rotary frame. A welding sleeve and a wire sleeve are detachably fixed to the mandrel. Warp grooves are circumferentially and evenly distributed in the wire sleeve. Threading channels corresponding to the warp grooves one to one are arranged on the mandrel. A weft electrode wheel and a weft wire wheel are arranged on the wire spool. Weft of the weft pay-off spool is wound on the periphery of warp at the welding sleeve through the weft wire wheel. The weft electrode wheel presses the weft and the pressing position is located between two pieces of warp and the weft. The weft electrode wheel is connected with a weft welding power supply. The welding sleeve is connected with a warp welding power supply. Threading of a warp steel wire of the forming device and installing of the welding sleeve are quite convenient, meanwhile it can be ensured that the warp steel wire and a weft steel wire make close contact during welding, and welding quality is better.

Description

technical field [0001] The invention relates to a forming device of a reticular steel skeleton, and also relates to a forming method of a reticular steel skeleton using the forming device. Background technique [0002] In the automatic production of steel wire reinforced composite pipes, it is necessary to add mesh steel wire skeleton to strengthen the composite pipes. At present, there are mainly two types of steel skeleton additions. One is to use multiple steel wires to wind into a mesh shape. The warp and weft steel wires are not welded. The steel skeleton of this steel wire reinforced composite pipe will slip. The quality is not stable, and the enhancement effect is relatively poor. And another kind of forming device of steel frame is to utilize the mode of continuous spot welding to complete the welding of warp and weft steel wires, for example, the patent of ZL98119383.8 discloses the manufacturing method and device of mesh steel frame--plastic composite pipe mesh st...

AI Technical Summary

Problems solved by technology

[0003] 1. The weft steel wire is wound on the warp wire by the self-tension of the welding roll, and the welding roll is still a long distance away from the solder joint. Between 20mm-60mm, this section of the weft steel wire still has a certain resistance, resulting in a loss of electricity. waste

[0004] 2. The weft wire is pressed on the warp wire by tension, and the tension is difficult to adjust. Therefore, once the weft wire and the warp wire are not in tight contact, the resistance during welding will increase, which will lead to welding poor effect
