[0003] The purpose of this invention is to provide a narrow profile with protrusions on the substrate, which, while ensuring sufficient strength, forms a narrow surface on the top of the substrate.

[0004] The objective of this invention is achieved through the following technical solutions.

[0005] A narrow profile is long and narrow, with a base and protrusions on the top of the base.

[0006] A narrow profile is long and narrow, with a base, a boss on the top of the base, and a protrusion on the top of the boss.

[0007] A narrow profile is long and narrow, with a base. A left boss is provided on the upper left side of the base, and a protrusion is provided on the upper right side of the base. A right boss is provided on the upper right side of the base, and a protrusion is provided on the upper right side of the base.

[0008] In a preferred manner, the height of the protrusion is ≤0.11mm to 0.02mm.

[0009] In a preferred embodiment, the height of the protrusion may be ≤0.09mm to 0.02mm, or ≤0.08mm to 0.02mm.

[0010] In a preferred manner, the protrusion is an arc-shaped surface or a circular arc surface.

[0011] In a preferred manner, the protrusion is partially elliptical.

[0012] In a preferred embodiment, the protrusion is formed by having a downward step.

[0013] In a preferred manner, the protrusion is a small trapezoid.

[0014] In a preferred manner, the protrusion is a small boss.

[0015] In a preferred embodiment, the protrusion has a small boss at the bottom and an arc-shaped or circular arc surface at the top.

[0016] In a preferred embodiment, a step is provided next to the protrusion below it.

[0017] In a preferred embodiment, a left step is provided on the left side next to the protrusion below; and a right step is provided on the right side next to the protrusion below.

[0018] In a preferred embodiment, a left step is provided on the left side and a right step is provided on the right side below the protrusion; the width of the left step is preferably equal to the width of the right step, and the protrusion is preferably located in the middle of the left and right steps.

[0019] In a preferred embodiment, the height of the protrusion is preferably 0.03 mm to 0.05 mm. More preferably, it is 0.03 mm to 0.06 mm. More preferably, it is 0.03 mm to 0.07 mm. More preferably, it is 0.03 mm to 0.08 mm.

[0020] In a preferred manner, the upper surfaces of the steps, left steps, and right steps located beside the protrusion are preferably flat.

[0021] In a preferred embodiment, the upper surfaces of the steps, left step, and right step located next to the protrusion are conical surfaces, and the angle between the conical surface and the horizontal plane is preferably ≤10 degrees.

[0025] According to a preferred embodiment, the substrate is made thin, such that the profile height is ≤1.65mm, preferably ≤1.5mm to 1.3mm, or preferably <1.4mm to 1.3mm. This makes it a profile with good flexibility.

[0026] This invention relates to steel profiles with extremely high manufacturing precision, particularly in the critical raised narrow surfaces, where the manufacturing tolerance can be achieved to <0.005mm. Furthermore, mass production ensures consistent precision, high production efficiency, and low energy consumption. This profile also boasts high strength and toughness. A particularly outstanding advantage is that its surface can be nitrided (using materials such as 6Cr13MO) and coated with a DLC coating that exhibits a low coefficient of friction and excellent wear resistance. Especially noteworthy is the ability to create raised, arc-shaped narrow surfaces on steel profiles, reducing the width of the steel profile substrate and the raised surfaces, resulting in exceptionally good performance.

[0099] The combined surface

[0022] is a combination of a plane and a circular arc surface, or a combination of a cone and a circular arc surface.

[0100] Holes

[0011] may be provided on the substrate of this narrow profile [1]. See Figure 28.

[0101] This profile is long and narrow. For ease of storage and transportation, it is often rolled into a coil.

[0102] The narrow-faced steel profile of the present invention has the following particularly significant advantages:

[0103] The steel profile in this invention's technical field is a narrow profile with a raised [2] on its upper surface, which significantly reduces the width of its upper surface. The raised [2] on this profile is the contact and friction surface for other product parts to be manufactured further, and for parts that cooperate with it. It can significantly reduce the width of its upper surface, greatly reduce the contact area, reduce friction, and save energy. In addition, the height of the raised [2] can be ≤0.11mm to 0.02mm. If the height of the raised [2] is less than 0.02mm, it is too low and will wear due to friction, resulting in a short service life. If the height of the raised [2] is greater than 0.11mm, it protrudes too much, and the profile is prone to damage such as bumps and dents during the further manufacturing and conversion into other product parts, resulting in a low yield; and the raised [2] of the product parts further manufactured using this profile is not firm enough. In particular, to increase the wear resistance of the protrusion [2], nitriding treatment is performed on the upper surface of the profile. If the protrusion [2] is too high, nitriding cracks will penetrate, break, or even fracture, which will affect the yield and reliability. The height of the protrusion [2] is preferably 0.03mm to 0.06mm, or 0.02mm to 0.08mm. This not only ensures a satisfactory yield in the manufacturing process of products made from this profile, but also provides a long service life and good reliability during use. It can avoid quality accidents caused by excessively high protrusion [2].

[0104] The height of the small boss

[0016] can be adjusted during the design process to accommodate the height of the protrusion [2]. The height of the protrusion [2] determines the service life and reliability of the parts made from this profile. The width of the small boss

[0016] is related to the width of the top of the protrusion [2], which determines the width of the contact surface of the parts made from this profile. In addition, the shape of the small boss

[0016] can be trapezoidal (small trapezoid), asymmetrical trapezoid, or semi-trapezoidal, etc. The shape and angle can be flexibly varied to meet the design requirements of various situations. It has better strength and performance.

[0105] A left step

[0019] is provided on the left side below the protrusion [2], and a right step

[0020] is provided on the right side below the protrusion [2], so that the base [1], the boss [3], the left boss [6] and the right boss [8] are widened in a stepped shape, so that the base [1] and the boss have sufficient strength. It also ensures that the protrusion [2] has sufficient strength and reliable and stable operation. In particular, the protrusion [2] is located in the middle position between the left step

[0019] and the right step

[0020] , which can stably support the protrusion [2]. The protrusion [2] with a small height (0.03mm to 0.06mm) is connected in the middle position between the left step

[0019] and the right step

[0020] , which together form a relatively wide and solid area, which can prevent the protrusion [2] and other parts from cracking and nitriding crack penetration during the further manufacturing of other product parts, protect the protrusion [2] from damage, and achieve a satisfactory yield. It can eliminate the fracture caused by nitriding of protrusions[2], ensure the reliability of use, and avoid quality accidents.

[0106] The upper surfaces of the left step

[0019] and the right step

[0020] are preferably flat. This helps to protect the protrusion [2] from damage.

[0107] The angle between the conical surface [4] and the horizontal plane should ideally be ≤10 degrees to avoid the bulge [2] from being excessively protruding and isolated, thus preventing cracks or breaks.

[0108] The upper surfaces of the steps, left step

[0019] and right step

[0020] located next to the protrusion [2] are configured as composite surfaces

[0022] . This not only protects the protrusion [2] from damage, but also allows for more flexible design, resulting in better performance of the profile.

[0109] A protrusion[2] is provided on this narrow profile, and its upper surface is a narrow surface, which can greatly reduce the width of the contact surface between the product parts made of this narrow profile and other mating parts, thus greatly reducing the contact area, reducing friction, and improving mechanical efficiency.

[0110] In particular, products made using the curved or rounded surfaces of this profile have excellent lubrication, strong pressure resistance, small contact area, and particularly good performance in their contact surfaces with mating parts.
