Description

Technical Field

[0001] The invention relates to the technical field of guide springs, in particular to a guide spring of an electric heating furnace control device. Background Art

[0002] The guide spring plays a major role in guiding and positioning the electric furnace control device. It is usually designed to have a certain degree of elasticity and recovery to ensure that during the operation of the electric furnace, the control device can accurately move to the predetermined position and maintain a stable operating state.

[0003] When the existing guide springs are used in electric heating furnaces, they may be affected by various factors such as high temperature, vibration and wear, which may cause them to be easily deformed and loose, making it difficult to maintain stable performance.

[0004] Therefore, we propose a guide spring for an electric furnace control device to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a guide spring for an electric furnace control device to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A guide spring for an electric furnace control device comprises an integrally formed mounting body, a positioning tube and a spring body, wherein the mounting body comprises a flat plate portion, a raised portion and a through hole, the center of the flat plate portion is punched to form the positioning tube, and both ends of the positioning tube are punched through to form a through hole, the raised portion is formed by bending the two ends of the flat plate portion toward one side of the positioning tube, the two sides of the raised portion are punched to form a spring body, and the spring body comprises a connecting portion, an extending portion and a rebound portion, the two ends of the extending portion are respectively bent to form a connecting portion and a rebound portion, and the connecting portion is connected to the raised portion.

[0007] In a further embodiment, the bending angle between the flat plate portion and the positioning tube is 90°.

[0008] In a further embodiment, the bending angle between the flat plate portion and the raised portion is 90°.

[0009] In a further embodiment, the spring bodies are symmetrically distributed on both sides of the positioning tube and the mounting body.

[0010] In a further embodiment, the width of the elastic sheet body is smaller than the outer diameter of the positioning tube.

[0011] In a further embodiment, the extension portion is bent toward a side away from the positioning tube, and a bending angle between the extension portion and the connecting portion is 105°.

[0012] In a further embodiment, the rebound portion is bent toward a side close to the positioning tube, and a bending angle between the rebound portion and the extension portion is 150°.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention arranges that the entire shrapnel structure is formed by punching, bending and other processes from a whole piece of material, and has higher stability. The cooperation between the flat plate portion and the positioning tube makes the entire shrapnel easier to position and assemble, and is not easy to loosen during use. The provided raised portion provides better support for the shrapnel body, so that the shrapnel body is not easy to deform under long-term extrusion and wear, and has better recovery ability, effectively maintaining its stable performance, thereby extending the service life of the shrapnel.
