The first strip-shaped plate is fixedly connected to the support, and both ends of the second strip-shaped plate are respectively installed on the connecting plates through rotating shafts, so that the second strip-shaped plate can be opened around the rotating shafts; since there is no blocking structure under the two strip-shaped plates, the second strip-shaped plate is conveniently opened and the spring is wound and then falls, and the problem that a bottom plate in the prior art hinders the falling spring is overcome.

Description

Technical Field

[0001] This invention relates to the field of spring component manufacturing technology, and more particularly to a guide rail for a spring with a large length-to-diameter ratio. Background Technology

[0002] Currently, many springs used in aviation involve large length-to-diameter ratios, typically ≥236. During manufacturing, these slender springs, due to their high length-to-diameter ratio and elastic nature, tend to sag as they are wound. This sag pulls on subsequent springs being processed, increasing gaps and failing to meet requirements. It can even cause bent springs to detach from the cutting tool, significantly negatively impacting product quality. Furthermore, this sag can cause the spring to serpentine in its free state, affecting its overall quality. Therefore, designing a device to improve spring manufacturing quality is crucial.

[0003] For example, patent application number CN201620227997.9 discloses a horizontal guide rail assembly for a spring press and the spring press. The rail body includes a base plate connected to a telescopic rod and two inclined support plates that are tilted outwards. The two inclined support plates can slide closer to or further away from each other on the bottom and are positioned on the base plate.

[0004] However, in the existing patented guide rails, when the finished spring needs to fall from the bottom of the guide rail to the bottom collection box, the base plate obstructs the falling spring, which is not conducive to practical use. Summary of the Invention

[0005] The main objective of this invention is to provide a guide rail with a large length-to-diameter ratio spring, aiming to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention proposes a guide rail for a spring with a large length-to-diameter ratio, comprising a first strip plate, a second strip plate, and a bracket; the first strip plate is fixedly connected to the bracket, and connecting plates are fixedly connected to both ends of the first strip plate; both ends of the second strip plate are respectively mounted on the connecting plates via rotating shafts; the first strip plate and the second strip plate form a V-groove structure; a reset structure is provided between the first strip plate and the second strip plate.

[0007] With the above structure, the wound spring is conveyed straight forward along the V-shaped groove formed by the first strip plate and the second strip plate, which avoids the wound spring from falling and affecting the quality of the spring being processed. After the entire spring is processed, the second strip plate is opened to facilitate the falling of the wound spring. After the wound spring falls, the second strip plate automatically closes under the action of the reset structure.

[0008] Preferably, the reset structure is a reset spring, with one end of the reset spring fixed on the long side of the second strip plate and the other end fixed on the plane of the first strip plate forming the V-groove.

[0009] Preferably, the bracket includes a telescopic support member, a horizontal plate disposed on the top side of the telescopic support member, and an L-shaped bracket disposed on the horizontal plate; the first strip plate is connected to the L-shaped bracket.

[0010] Preferably, a waist-shaped groove is provided on the horizontal plate, and the horizontal plate and the L-shaped bracket are connected by bolts, with the bolts passing through the waist-shaped groove. By providing the waist-shaped groove, the L-shaped bracket can be adjusted to move along the length of the waist-shaped groove, thereby adjusting the position of the V-shaped guide rail formed by the first strip plate and the second strip plate, which facilitates alignment with the spring machine.

[0011] Preferably, the telescopic support is a telescopic rod, a telescopic cylinder, or an electric telescopic cylinder.

[0012] Preferably, a connecting block is provided at the bottom of the telescopic support member. This connecting block is perpendicular to the axis of the telescopic support member and is used to insert into the spring machine. By providing the connecting block, the guide rail can be installed simply by inserting it directly into the spring machine.

[0013] Preferably, the connecting plate is arc-shaped. By setting the connecting plate to an arc shape, interference with the processed spring is avoided.

[0014] Preferably, a first narrow plate and a second narrow plate are respectively provided at one end of the first strip plate and the second strip plate for extending into the spring machine to better guide the processed spring. The width of the first narrow plate and the second narrow plate are respectively smaller than the width of the first strip plate and the second strip plate.

[0015] Preferably, the first narrow plate and the second narrow plate are provided with chamfered angles. By providing the chamfered angle structure, interference between the narrow plate and the spring mechanism is further avoided.

[0016] Preferably, the first narrow plate and the first strip plate are integrally formed; the second narrow plate and the second strip plate are also integrally formed. Using an integrally formed structure ensures that the surfaces of the first narrow plate and the second narrow plate that form the V-groove with the first strip plate and the second strip plate are on the same plane. If a separate structure is used, the resulting seam can easily affect the guidance of the processed spring.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: (1) In this invention, a guide rail forming a V-groove structure using a first strip plate and a second strip plate is installed in the direction of spring winding and conveying, so that the spring is conveyed in a straight direction along the V-groove during processing. Since the first strip plate is fixed to the bracket, and both ends of the second strip plate are respectively mounted on the connecting plate via rotating shafts, the second strip plate can be opened around the rotating shafts, making it convenient to remove the wound spring from the fall. In addition, by providing a reset structure between the first and second strip plates, when the wound spring falls, the reset structure causes the second strip plate to automatically rotate and reset, forming a V-groove structure with the first strip plate again. This invention simplifies the processing operation and improves processing efficiency.

[0018] (2) In this invention, the first strip plate is fixed to the bracket, and the two ends of the second strip plate are respectively mounted on the connecting plate through the pivot, so that the second strip plate can be opened around the pivot. Since there is no obstruction structure under the two strip plates, the opening of the second strip plate facilitates the winding of the spring to fall, overcoming the problem that the bottom plate in the prior art hinders the falling spring.

[0019] (3) In this invention, a waist-shaped groove is provided on the horizontal plate, and the horizontal plate and the L-shaped bracket are connected by bolts, with the bolts passing through the waist-shaped groove. By providing the waist-shaped groove, the L-shaped bracket can be adjusted to move along the length of the waist-shaped groove to adjust the position of the V-shaped guide rail formed by the first strip plate and the second strip plate, which is convenient for aligning with the spring machine. With the help of the telescopic support, the height can be adjusted, thereby adjusting the height of the guide rail formed by the V-shaped groove structure of the first strip plate and the second strip plate, so as to be suitable for different models of spring machines.

[0020] (4) The guide rail provided by the present invention is suitable for the processing and conveying of springs with a large length-to-diameter ratio. Attached Figure Description

[0028] With the above structure, the wound spring is conveyed straight forward along the V-shaped groove formed by the first strip plate 1 and the second strip plate 2, which avoids the wound spring from falling and affecting the quality of the spring being processed. After the entire spring is processed, the second strip plate 2 is opened to facilitate the falling of the wound spring. After the wound spring falls, the second strip plate 2 automatically closes under the action of the reset structure.

[0029] In this embodiment, the reset structure is a reset spring 9. One end of the reset spring 9 is fixed on the long side of the second strip plate 2, and the other end is fixed on the plane of the first strip plate 1 forming a V-groove.

Further, a waist-shaped groove 10 is provided on the horizontal plate 5, and the horizontal plate 5 and the L-shaped bracket 6 are connected by bolts, with the bolts passing through the waist-shaped groove 10. By providing the waist-shaped groove 10, the L-shaped bracket 6 can be adjusted to move along the length of the waist-shaped groove, thereby adjusting the position of the V-shaped guide rail formed by the first strip plate 1 and the second strip plate 2, facilitating alignment with the spring machine.

[0031] In this embodiment, the telescopic support 4 is a telescopic rod, a telescopic cylinder, or an electric telescopic cylinder.

The widths of the first narrow plate 11 and the second narrow plate 12 are smaller than the widths of the first strip plate 1 and the second strip plate 2, respectively. Furthermore, chamfered angles 13 are provided on the first narrow plate 11 and the second narrow plate 12.

[0035] In this embodiment, the first narrow plate 11 and the first strip plate 1 are integrally formed; the second narrow plate 12 and the second strip plate 2 are integrally formed.
