[0001] This utility model relates to the field of bearing material processing technology, specifically to a multi-purpose cutting steel blade for hot cutting of bearing hot material sections. Background Technology
[0002] In the bearing manufacturing industry, hot cutting of the hot material section is a crucial step, as its cutting quality and efficiency directly affect subsequent processing steps and the performance of the final product. Traditional hot cutting blades are typically designed for single-sided use, meaning there is only one cutting surface on the blade. When this cutting surface wears or is damaged due to prolonged use, the entire blade needs to be replaced. This not only increases production costs but also reduces production efficiency. Furthermore, frequent blade replacements can affect the consistency and stability of cutting, thereby impacting the overall quality of the bearing product.
[0003] With the increasing demands for production efficiency, cost control, and product quality in the bearing manufacturing industry, traditional single-sided cutting blades can no longer meet the needs of modern production. Therefore, it is particularly important to develop a multi-purpose steel cutting blade with multiple cutting surfaces that can extend service life, reduce replacement frequency, and ensure cutting quality.

The bottom edge of the mounting side plate is provided with a concave arc-shaped clearance groove corresponding to the concave arc-shaped blade edge. A limiting block for limiting the top edge of the blade body is detachably provided on the mounting side plate. The mounting side plate is provided with a through groove that corresponds to and mates with the countersunk hole.
[0008] Furthermore, the blade body includes a cutting surface, and the side of the blade body is square.
[0009] Furthermore, the through groove includes a vertically arranged movable positioning groove and an arc-shaped adjustment guide groove disposed between two adjacent movable positioning grooves, and multiple arc-shaped adjustment guide grooves are connected to form an annular channel.
[0010] Furthermore, the top of the mounting side plate is provided with a top plate for fixed connection with the upper template, and an L-shaped connector is provided below the top plate. The free end of the crossbar of the L-shaped connector is connected to the center of the annular groove on the mounting side plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0025] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.
[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0027] An embodiment of the multi-purpose steel cutting blade for hot cutting of bearing hot material sections provided by this utility model:
[0028] As shown in Figures 1 to 4
[0029] The blade body 1 is detachably mounted on the blade holder 2. The blade body 1 includes four cutting surfaces 11. The side of the blade body 1 is square, and each cutting surface 11 is provided with a concave arc-shaped cutting edge 12.
[0030] In this embodiment, the thickness of the blade body 1 is 5cm.
[0031] The blade body 1 has multiple usable cutting surfaces. By rotating the blade body 1, the concave arc-shaped cutting edges 12 on different cutting surfaces 11 can be used with the face down, which greatly increases the number of usable cutting edges. In this embodiment, the four cutting surfaces can theoretically achieve the use of eight cutting edges (both the front and back surfaces have concave arc-shaped cutting edges), which effectively extends the service life of the blade body 1 and reduces the frequency of replacing the blade body 1.
[0032] The blade body 1 has countersunk holes 13 on both sides of its edge for connecting with the blade holder 2.
[0033] By setting countersunk holes 13, when the bolt is connected to the blade holder 2, the end of the bolt is recessed into the blade body 1, which avoids interference with materials or other components during the cutting process and ensures the smooth progress of the cutting operation.
[0034] In this embodiment, the blade holder 2 includes a mounting side plate 21. One side of the mounting side plate 21 is provided with a limiting bottom plate 22 for limiting the bottom edge of the blade body 1. The bottom edge of the mounting side plate 21 is provided with a concave arc-shaped clearance groove 221 corresponding to the concave arc-shaped blade edge 12. A limiting block 23 for limiting the top edge of the blade body 1 is detachably provided on the mounting side plate 21. The mounting side plate 21 is provided with a through groove 24 corresponding to the countersunk hole 13.
[0035] The positioning and installation of the blade body 1 are achieved through the cooperation of the limiting base plate 22 and the limiting block 23, which also helps to improve the stability of the blade body 1 during installation.
[0036] In this embodiment, the through groove 24 includes a vertically arranged movable positioning groove 241 and an arc-shaped adjustment guide groove 242 disposed between two adjacent movable positioning grooves 241. Multiple arc-shaped adjustment guide grooves 242 are connected to form an annular channel. Through the structural design of this through groove 24, rotation adjustment can be completed without disassembling the blade body 1, which improves the adjustment efficiency and avoids the cumbersome disassembly and installation caused by completely removing the bolts and then adjusting the position.
[0037] In this embodiment, the top of the mounting side plate 21 is provided with a top plate 25 for fixed connection with the upper template, and an L-shaped connector 26 is provided below the top plate 25. The free end of the crossbar of the L-shaped connector 26 is connected to the center of the annular groove on the mounting side plate 21. The L-shaped connector 26 ensures the integrity of the structure of the mounting side plate 21.
[0038] In this embodiment, the limiting blocks 23 are two arranged at intervals on both sides of the concave arc-shaped cutting edge 12 at the top of the blade body 1, and the end of the limiting block 23 pointing towards the blade body 1 is provided with a guide slope.
[0039] The mounting side plate 21 and the vertical plate of the L-shaped connector 26 are provided with slots that allow the limiting block 23 to slide through.
[0040] The limiting block 23 is detachable. When the orientation needs to be adjusted, it can be removed to avoid interfering with the adjustment of the blade body 1. After adjustment, the limiting block 23 is reinstalled to improve the overall structural coordination.

They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
[0042] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
