Abstract

The utility model relates to a coiling mould of a conjoined tension spring, which comprises a spring coiling paw head module, a spring coiling mould core, a steel wire press shaft, a hand crank and a mould core bracket. The utility model is characterized in that the spring coiling mould core is connected with the mould core bracket, one end of the spring coiling mould core is connected with the crank handle, and the other end of the spring coiling mould core is sheathed with the spring coiling paw head module; the rotary steel wire press shaft is connected with a position near the spring coiling mould core; a position near a sheath hole of the spring coiling paw head module is provided with a steel wire through hole. The utility model can symmetrically control the conjoined tension spring on left and right sides, and the operation and use is convenient. The length of a conjoined steel wire of a double tension spring can be prolonged optionally, the specification of a same batch of products is the same and the quality of the products is guaranteed.

Description

The winding mould of disjunctor extension spring

Technical field

The utility model relates to a kind of winding mould of disjunctor extension spring.

Background technology

Extension spring is widely used in workers and peasants' production, and the disjunctor extension spring is meant that the two ends of same steel wire are wound with two extension springs.Characteristics such as it is widely used on mattress, the car seat cushion etc., and it is few to have a consumptive material, easy to use, are made by hand and are difficult to the standard of ensuring the quality of products disjunctor extension spring production technology trouble.

Summary of the invention

The purpose of this utility model just provides a kind of coiling disjunctor extension spring mould.

The utility model is achieved like this, it comprises around spring pawl head module, around spring core rod, steel wire last item, wind, die spider, it is characterized in that being connected on the die spider around the spring core rod, one end connects wind, other end socket is around spring pawl head module, be connected with rotating steel wire last item around the next door of spring core rod, have the steel wire perforation around the trepanning next door of spring pawl head module.

The utility model can the extension spring of symmetrical coiling disjunctor, and easy for operation, the disjunctor steel wire length of two extension springs can elongate arbitrarily, with batch product specification the same, guarantee product quality.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model work schematic diagram.

Fig. 3 is disjunctor extension spring product structure figure.

Specific implementation method

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises that around spring pawl head module (1), around the spring spring other end insertion threaded hole of steel with extension spring leans against on the steel wire last item, the backward rotation wind, and then the disjunctor extension spring of symmetry forms.Core rod (2), steel wire last item (3), die spider (4), wind (5), be connected on the die spider (4) around spring core rod (2), one end connects wind (5), other end socket is around spring pawl head module (1), be connected with the steel wire last item (3) of rotation around the next door of spring core rod, have steel wire perforation (7) on trepanning (6) next door around spring pawl head module.During use, as long as people will be enclosed within on the spring core rod around spring pawl head module, one end of finer wire (8) is passed threaded hole of steel, lean against on the steel wire last item rotary handle crank, then finer wire will be around on the spring core rod, take out extension spring,, accuse on the steel wire last item the other end insertion threaded hole of steel of the spring of relieving, the backward rotation wind, then the disjunctor extension spring of symmetry forms.

Claims

1, a kind of winding mould of disjunctor extension spring, it comprises around spring pawl head module, around spring core rod, steel wire last item, wind, die spider, it is characterized in that being connected on the die spider around the spring core rod, one end connects wind, other end socket is around spring pawl head module, be connected with rotating steel wire last item around the next door of spring core rod, have the steel wire perforation around the trepanning next door of spring pawl head module.
