Description

Technical Field

[0001] This utility model relates to the field of roller blackening technology, specifically to a batch roller blackening equipment. Background Technology

[0002] Black oxidation, or blackening for short, is a common surface chemical treatment method. Blackening improves the wear resistance and rust prevention of steel materials. Bearings in demanding industries such as wind power and tunnel boring machines often require blackening treatment of the bearing rings and rolling elements to improve surface quality. Blackening is typically done using an immersion method, where the steel product is placed in a prepared high-temperature blackening solution. After a certain period of chemical reaction, a black film forms on the surface of the steel product, completing the blackening process. For rollers, the blackened layer must be uniform and free of breaks.

[0003] In existing technologies, the blackening process typically involves supporting one end of the roller with angle steel and then placing a batch of rollers obliquely into a blackening tank to ensure full contact between the blackening liquid and the rollers. The drawback of this method is that the portion of the roller raceway surface in contact with the angle steel does not fully contact the blackening liquid, leading to blackening faults in that area. Furthermore, since the roller raceway surface is a stress-bearing area, uneven stress distribution on the raceway can easily occur, causing significant damage.

[0004] In addition, the circulation direction of the blackening liquid in the blackening pool is from bottom to top. The method of using the angle steel to tilt the rollers will cause the flow of the blackening liquid to become worse at the angle steel, especially near the fulcrum. This may have a certain impact on the blackening effect at that point, resulting in marks on the appearance of the rollers.

[0005] In conclusion, it is necessary to design a better roller blackening device that can achieve the ideal blackening effect by fully and evenly contacting the blackening liquid. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a novel batch roller blackening equipment.

[0007] The technical solution adopted by this utility model is: a batch roller blackening device, including multiple connecting plates and multiple supporting plates. Each connecting plate has several grooves that are spaced apart. The positions of the grooves on the multiple connecting plates are corresponding to each other. Each supporting plate has at least one V-shaped groove. The multiple supporting plates are arranged parallel to each other and are clamped in the grooves of the connecting plates through their bottom edges to form multiple rows of support structures for supporting the rollers.

[0008] As a preferred embodiment, the width of the groove is the same as the thickness of the supporting plate, and the spacing between each groove is equal.

[0009] As a preferred embodiment, the support plate is provided with several V-shaped grooves, and the positions of the V-shaped grooves on adjacent support plates correspond to each other.

[0010] As a preferred embodiment, the spacing between the two rows of rollers is greater than half the diameter of the rollers.

[0011] As a preferred embodiment, the roller is placed horizontally on the support plate, with the chamfered part of the roller in contact with the support plate.

[0012] As a preferred embodiment, the supporting plate and the connecting plate are made of thin plates with a thickness of 3mm-6mm, and the two are assembled by a slot connection method.

[0013] The beneficial effects of this utility model are:

[0014] In view of the shortcomings of the existing technology, this utility model provides a batch roller blackening tooling. Through optimized structural design, this utility model has the following technical effects:

[0015] Firstly, this invention incorporates V-grooves on a supporting thin plate and places the rollers horizontally within the support structure formed by adjacent V-grooves. This ensures the rollers contact the supporting thin plate only through the chamfered area, avoiding direct contact between the raceway surface and the tooling. This design solves the problem of blackening discontinuity on the raceway surface caused by traditional angle steel support methods. Furthermore, by controlling the spacing and angle of the V-grooves, sufficient intervals are ensured between the rollers, allowing the blackening liquid to flow evenly and fully contact the roller surface, thereby improving the uniformity and comprehensiveness of the blackening effect.

[0016] Secondly, this invention utilizes the interlocking and matching of grooves on the connecting plate and the supporting plate, along with a slot connection method to fix multiple rows of supporting plates onto the connecting plate, forming a stable support structure. This design not only simplifies the tooling assembly process but also reduces the equivalent area of ​​the tooling in the radial direction, minimizing the obstruction to the flow of the blackening liquid. This ensures that the roller can fully contact the blackening liquid during the blackening process, improving blackening efficiency and quality.

[0017] Thirdly, the connecting thin plate in this utility model is provided with several grooves for fixing the supporting thin plate. By fixing different numbers of supporting thin plates, support structures of different widths can be formed. At the same time, the angle of the V-groove on the supporting thin plate can also be adjusted, thereby forming a support structure suitable for different rollers, which greatly expands the scope of application of this utility model.

[0024] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0026] To more clearly describe the specific structural composition of this batch of roller blackening equipment, in conjunction with the attached... Figure 1 -Appendix Figure 4 This embodiment is described in detail below:

[0027] This embodiment provides a batch roller blackening fixture, including multiple connecting plates 3 and multiple supporting plates 2. Each connecting plate 3 has several spaced grooves 3-1, and the grooves 3-1 on the multiple connecting plates 3 are positioned corresponding to each other. Each supporting plate 2 has at least one V-shaped groove. The multiple supporting plates 2 are arranged parallel to each other and are clamped into the grooves 3-1 of the connecting plates 3 by their bottom edges to form multiple rows of support structures for supporting the rollers. The rollers 1 are placed horizontally on the supporting plates 2, and the chamfered part of the rollers 1 is in contact with the supporting plates 2. The entire fixture is placed on a grid-like pallet, and the batch of rollers is sent into the blackening tank for full blackening by lifting the pallet.

[0028] Furthermore, the width of the groove 3-1 is the same as the thickness of the supporting thin plate 2, and the spacing between each groove 3-1 is equal.

[0029] Furthermore, the support plate 2 is provided with a plurality of V-shaped grooves, and the positions of the V-shaped grooves on adjacent support plates 2 correspond to each other. According to the length of the roller, the appropriate "V" angle 2-2 and the height 2-1 of the support plate are determined.

[0030] In this embodiment, the distance 1-2 between each row of rollers should be more than half the length of a roller to ensure sufficient contact between the rollers and the blackening liquid; at the same time, the distance 1-2 between each row of rollers should not be too large, otherwise it will waste space and reduce the blackening efficiency.

[0031] Furthermore, the spacing 1-2 between the two rows of rollers 1 is greater than half the diameter of the roller 1. The connecting plate 2 is provided with multiple grooves 3-1, the width of which is the same as the thickness of the supporting plate 3. Multiple supporting plates 2 are arranged side by side on the connecting plate 3. Two adjacent supporting plates 2 support one row of rollers 1. These two adjacent supporting plates 2 form a group of supporting plates 2, and each group of supporting plates 2 is separated by a groove 3-1. Therefore, the spacing 3-2 between adjacent grooves needs to be designed according to the diameter of the roller 1 to ensure that a group of supporting plates 2 can firmly fix one row of rollers 1. At the same time, the distance 1-1 between two rows of rollers 1 needs to be controlled to be more than half the diameter of the roller 1. Therefore, the dimensions of this fixture must not only maximize the use of space, but also ensure that there is a certain distance between the rollers to ensure that the flow of blackening liquid between the rollers is not affected, and to ensure full contact with the roller surface to ensure the blackening effect.

[0032] Compared to the angled placement method, this "V"-shaped placement of the rollers avoids contact between the roller raceway surface and the tooling support point. Instead, the chamfered area of ​​roller 1 contacts the support point, ensuring that the blackening of the roller raceway surface is seamless. Simultaneously, the horizontal placement of roller 1, perpendicular to the upward flow direction of the blackening liquid, ensures uniform flow and contact of the blackening liquid at every point on the roller raceway surface.

[0033] Optionally, the supporting plate 2 and the connecting plate 3 are made of thin plates with a thickness of 3mm-6mm, and are assembled by means of a slot connection.

[0034] In this embodiment, the operator selects five connecting plates 3, each with fifteen grooves, and ten supporting plates 2, each with four V-grooves. The supporting plates 2 are inserted in pairs into the grooves 3-1 on the connecting plates 3 to form a batch of roller blackening equipment, with each pair of supporting plates 2 separated by one groove 3-1.

[0035] In this implementation, the tooling uses 3mm thin plates connected by slots, which reduces the equivalent area in the radial direction and greatly reduces the obstruction of the blackening liquid flowing from bottom to top. The effect achieved is almost close to suspending the roller neatly in the blackening liquid for full blackening.

[0036] It should be noted that this utility model can form support structures of different widths by fixing different numbers of support plates. At the same time, the angle of the V-groove on the support plate can also be adjusted, thereby forming support structures suitable for different rollers. Support structures formed by adjusting the number of support plates and the angle of the V-groove are all within the protection scope of this utility model.

[0037] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
