Automatic spring coiling equipment of measuring tape

Abstract

The invention relates to automatic spring coiling equipment of a measuring tape, in particular to measuring tape spring coiling equipment which can precisely control the model, the length and the dynamics of a coiling spring in high-speed running and can automatically anneal the part of the coiling spring needing to be annealed. The automatic spring coiling equipment comprises a controller, a rack, an unwinding mechanism, a feed mechanism, a punching mechanism and a spring coiling mechanism, wherein the unwinding mechanism, the feed mechanism, the punching mechanism and the spring coiling mechanism are sequentially arranged on the rack. A spring belt is wound on the unwinding mechanism, and an electromagnetic heating induction coil as an annealing mechanism is also arranged on the rack between the unwinding mechanism and the feed mechanism. Horizontal grooves used for causing the coiled measuring tape to horizontally pass are formed between the unwinding mechanism and the electromagnetic heating induction coil, between the electromagnetic heating induction coil and the feed mechanism, between the feed mechanism and the punching mechanism, and between the punching mechanism and the spring coiling mechanism. The equipment can precisely determine the lengths of the spring head and the spring tail of the coiling spring in the high-speed running, and meanwhile can anneal the spring head and the spring tail of the coiling spring together or anneal any one of the spring head and the spring tail.

Description

technical field [0001] The invention relates to an automatic tape spring coiling device, in particular to an automatic tape spring coiling device capable of accurately controlling the shape, length and strength of a coil spring during high-speed operation, and capable of automatically annealing the part of the coil spring that needs to be annealed. Background technique [0002] At present, the automatic spring coiling equipment for tape measures on the market has different shapes and sizes of the inner diameter of the coil spring, which affects the quality of the coil spring. The mechanical failure caused by the quality of the spring belt cannot be quickly eliminated, resulting in low production efficiency and high labor intensity for workers. The equipment does not have annealing equipment, or the annealing area is uneven and the annealing intensity cannot be adjusted freely, which will affect the quality of the entire coil spring. Most of the unwinding mechanism adopts fre...

Problems solved by technology

[0002] At present, the tape measure automatic coil spring equipment on the market has different coil spring inner diameter shapes, which affects the coil spring quality.

The mechanical failure caused by the quality of the spring belt cannot be quickly eliminated, resulting in low production efficiency and high labor intensity for workers

The equipment does not have annealing equipment, or the annealing area is uneven and the annealing intensity cannot be adjusted freely, which will affect the quality of the entire coil spring. Most of the unwinding mechanism adopts free dragging and unloading, resulting in a large load on the coil spring motor, serious machine wear, and product scrapping high rate
