Spiral metal sheet winding forming device

Abstract

The invention relates to the technical field of machining and provides a spiral metal sheet winding-forming device. The spiral metal sheet winding-forming device comprises a base material fixing seat, a base material supporting seat and a sliding seat provided with a metal sheet coiled material, wherein a rotary chuck is arranged on the base material fixing seat, a metal sheet fixing clamp is installed on the rotary chuck, a positioning chuck is arranged on the base material fixing seat, a base material is installed between the rotary chuck and the positioning chuck, and one end of a metal sheet is installed on the metal sheet fixing clamp. The sliding seat is installed on a linear guiding rail in a sliding mode. The base material is installed between the base material fixing seat and the base material supporting seat, two ends of the base material are fixedly arranged, and the phenomenon that non-uniform sheet winding is caused by instable rail axis during rotation and the product quality is affected is avoided. Due to the fact that the metal sheet coiled material is arranged on the sliding seat, the sliding seat is installed on the linear guide rail in a sliding mode, the sliding seat slowly moves according to a screw pitch while sheet winding, the screw pitch accuracy of the spiral metal sheet is ensured, and spiral metal sheet winding accuracy and quality are improved.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a coil forming device for spiral metal sheets. Background technique [0002] At present, finned tubes are widely used in petrochemical, shipbuilding, automobile, papermaking, refrigeration and many other industries as heat exchange and heat dissipation components. The forms of existing finned tubes are mostly sleeve type and spiral wound type. The sleeve type is mostly a mechanical set, which has high noise, poor stability and safety; the equipment price is relatively expensive, and the technical requirements for the maintenance personnel are high and the productivity is low. The sheet-wound type is a long strip-shaped metal sheet with good thermal conductivity that is connected with a metal tube by winding, embedding, folding and welding methods to form a spiral-shaped finned tube.

Problems solved by technology

[0003] Spiral-wrapped finned tubes first wrap metal sheets on the outside of the heat pipe, generally using manual winding and mechanical winding. The obvious disadvantages of manual winding are low efficiency, slow speed, and inaccurate control of pitch by manual winding, resulting in spiral The winding of the sheet is uneven, which affects the quality of the heat pipe; although the mechanical winding method is fast and inefficient, because the existing mechanical winding equipment is too simple, a chuck driven by a motor is generally used to fix the pipe, and the metal sheet It is easy to shift and deform during the winding process, and the winding quality of the spiral sheet is not high, which cannot meet the production needs
