Automatic scroll spring forming apparatus

Abstract

The automatic scroll spring forming apparatus includes a disc type feeder frame, a material failure optoelectronic controller, a length determining feeder, a punch with die, a high frequency annealer, an electromagnetic sucking head, a crimper, a former, a hook feeding device, a hook bender, an unloading device, an acceptor, a collector and controlling system. Under the control of the controlling system, the present invention completes the whole process including material feeding, cutting, high frequency annealing, bending hook, feeding hook, curling, unloading and collecting. The present invention has the advantages of integrated production line, low production cost, high product precision, etc.

Description

technical field [0001] The invention relates to an automatic spring forming device, in particular to a scroll spring automatic forming device capable of cutting a steel strip to a fixed length, annealing, hooking and crimping. Background technique [0002] The general steps of the existing scroll spring processing are as follows: first cut the entire steel strip according to the length requirement, after cutting, manually bind it according to a certain number, then the workers move the cut steel strip to the high-frequency annealing area, and the whole bundle The material is placed flat on the workbench, and the two ends of the steel strip are manually annealed. The annealing time and material annealing length are determined by the experience of the operator; after the annealing process, the worker moves it to the hook processing area, and manually , After debugging the special mold and punching machine, the material heads are sent into the mold one by one manually, and sent...

AI Technical Summary

Problems solved by technology

The annealing process is controlled by manual experience to control the annealing length and time, which is far from the consistency and stability of annealing; the manual hook, the length of the hook determined by manual positioning and manual operation alone cannot reach the consistency of the product, and There are certain potential safety hazards; manual feeding of hooks, manual operation of curling, high labor intensity, and potential safety hazards. At the same time, the site is spread out during the transfer between processes, and manual handling alone is labor-intensive.

It can be seen that the entire spring manufacturing process is basically carried out manually, and some processes are completely controlled by manual experience. The product process is complicated, the operation is very inconvenient, and the labor intensity of the operator is high, there are certain safety hazards, and the equipment and handling occupy a large area. , and the prepared spring has poor consistency, it is difficult to meet the high precision requirements, and each process needs to be equipped with an operator to operate and process
