Abstract

Device for manufacturing springs, which is intended to manufacture springs or bass drums for percussion boxes corresponding to musical instruments, and whose manufacture can be made to the desired length, is characterized because it is constituted from a bridge or former with a transverse hole through which a mother thread is passing through, on the one hand, it is linked to the head of a turning motor and on the other end to a bearing mounted on a fixed support, keeping said mother wire tense, with the particularity of that a second element that is to constitute the bead or spring proper, also held in the head of the motor, runs in a relaxed and through a hole of the same former, this hole being perpendicular to the passage of the mother wire, so that the rotation of the motor head carries with it the winding of the element that has to form the bead or spring around the mother wire, obtaining the econ the length you want.

Description

Device for manufacturing springs.

Object of the invention

The present invention relates to a device for manufacturing springs, specifically springs called beards that are used as ropes in boxes of percussion of musical instruments such as drums and Similar.

The object of the invention is to be able to manufacture springs of the type referred to above, with a large length and enable roll storage to facilitate acquisition of the measure that in each case the user wants or consumer.

Background of the invention

Currently, the manufacturing systems of percussion box springs are planned to perform only springs with limited dimensions, and that correspond to the standard measurements of the classic strings of batteries or those provided for similar musical instruments of percussion.

This limitation is a shortage in the manufacturing process and therefore a higher economic cost for the consumer.

Description of the invention

The device that has been recommended has been conceived to solve the problem previously exposed, since which is planned to allow the manufacture of springs, of greater or less thick, but with great length, making it possible for the springs have the ability to get on a roll and leave providing in the length that each user wants.

More specifically, the device of the invention is constituted from a constitutive piece of a form through which a length thread is passed variable, which is related to the head of a turning motor in which the element that is to constitute the bead or spring itself, so that the mother thread, from the rotation motor head, it is passed through a hole established for that purpose in the former, and is tensioned by its end on a bearing mounted on a fixed support, while that the element or thread that will form the curb or spring, runs from the commented head of the rotation motor, and in position distended is passed through another transverse hole to the passage of mother wire, so that the rotation of that motor head carries with it the winding of the element around the mother wire, forming thus the curb or spring, with the desired length.

Based on the bearing that holds and tightens the thread mother, you get this one, having to be perfectly stretched, do not break by twisting.

According to another of the characteristics of the invention, it is envisioned that the former be movable longitudinally along a guide arranged parallel to the mother thread, in order to improve the stability conditions of said former.

As is evident, these curbs or springs are of very small diameter although this is variable depending on the type of percussion box in which it is applied, and being preferably made of carbon steel with different types of finishing, being manufactured closed and being able to be placed in such situation or more or less stretched as it deems appropriate luthier, determining in all cases a hollow element and flexible.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation longitudinal of the device of the invention intended for manufacturing curbs or springs.

Figure 2.- Shows a representation according to a perspective corresponding to the detail of the passage of the threads to across the bridge or former

Preferred Embodiment of the Invention

As you can see in the referred figures, the device of the invention is constituted from a form (1) equipped with a transverse hole through which it is through a mother wire (2) that at one end is mounted on the head (3) of a turning motor (4), while at its other end it is through a bearing (5) mounted on a support (6) properly anchored or fixed.

The mother thread (2) will be of indefinite length and it will remain tense between the head (3) of the drive motor (4) and the bearing (5).

A second element (7) that will constitute the bead or dock proper, also runs from the engine head (3) (4), distended from there, and posing as an axial hole of the former (1), that is a hole perpendicular to the passage of the mother wire (2), all of such that the rotation of the head (3) produced by the motor (4) carries with it the winding of the element (7) on the mother thread (2) and consequently the conformation of the dock or staff proper, which as is evident may be of length undefined

The mother thread (2) in its hold on the bearing (5) will rotate freely to prevent torsional breakage, being removed once the spring is obtained.

For better stabilization of the former (1), it is planned that it can be moved along a guide, not represented in the drawings, a guide that will obviously be parallel to the mother thread (2).

Therefore, the length of said spring or refrain may be any, logically depending on the Length of both the mother wire (2) and the element (7) that is going to form that curb or dock, being able to finish the manufactured or conformation at the time you want and give it to the dock or bead the length you want, which allows your winding on a reel or coil to get a roll of the to be able to extract the desired length and supply the consumer of the required spring or bead length, or well go sectioning sections to form strings of instruments percussion, with the desired lengths.

As already said, the element (7) with which the spring or bead is manufactured, it may have different diameters, for example between 0.15 and 0.55 mm, in terms of springs or curbs that must form ropes used in drawers of Peruvian percussion or flamenco.

Claims (2)

1. Device for manufacturing springs, which being intended to manufacture springs or beadings for percussion boxes corresponding to musical instruments, and whose manufacture can be carried out with the desired length, is characterized in that it is constituted from a bridge or former with a transverse hole through which a mother wire is passed through, which, on the one hand, is linked to the head of a turning motor and on the other end to a bearing mounted on a fixed support, keeping said mother thread tense, with the particularity of that a second element that will constitute the curb or spring itself, also held in the motor head, runs distended and through an orifice of the same form, this orifice being perpendicular to the passage of the mother wire, so that the rotation of the motor head carries with it the winding of the element that must form the bead or spring around the mother wire, obtaining the muell e with the desired length. 2. Device for manufacturing springs, according to claim 1, characterized in that the former is movable along a longitudinal guide parallel to the mother wire.
