Abstract

The invention discloses a forming tool for draw spring mouth closing. The tool comprises a mold handle, an upper module, a lower module, a template and a fixing screw; the lower module is fixed to thetemplate by the fixing screw, the upper module is arranged on the lower module, and the mold handle is fixed to the upper module; during working, a draw spring before the draw spring to be processedis combined is placed on the lower module, the punching machine drives the mold handle, thereby driving the upper module to move up and down, the draw spring before combination is closed and processed, a hook of the draw spring is processed, and the combined draw spring is processed. The tool improves the dimensional stability of produced draw spring parts and improves work efficiency.

Description

1. Technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a forming tool for closing the mouth of a tension spring. 2. Background technology [0002] Extension springs are helical springs that bear axial tension. Extension springs are generally made of circular cross-section materials. When not under load, the coils of the extension spring are generally tight and there is no gap. Extension springs are suitable for high and low temperature, corrosion-resistant and other working environments. The materials mainly include stainless steel spring wires, carbon steel wires, oil quenched and tempered alloy spring wires, high and low temperature alloy spring wires, etc. [0003] At present, in the production process, manual combination processing is usually used for the combined production of extension springs and draw hooks. The labor intensity of production workers is high and the efficiency is low. Different production worke...
