Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a scraper-type saw blade. Background Technology

[0002] Saw blades are a general term for thin, round cutting tools used to cut solid materials. Saw blades used for cutting wood have scrapers fixed to their sides to protect the steel plate from deformation during use and make the cut surface of the wood smoother. However, if the blade is welded directly to the saw blade, it will cause the saw blade to deform and crack, and the fixing force will be insufficient, making it easy to break off. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a scraper-type saw blade, which solves the existing problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a scraper-type saw blade, including a saw blade body, an opening inside the saw blade body, a sandwich layer on one side of the opening, a clamping opening inside the sandwich layer, a scraper fixedly connected inside the clamping opening, and linear holes inside the saw blade body, the linear holes being arranged in four groups in a circumferential distribution.

[0005] Preferably, the openings are provided in multiple sets arranged in opposite directions, and the openings are C-shaped.

[0006] Preferably, the scraper is provided in multiple sets, all of which are located inside the opening.

[0007] Beneficial effects

[0008] This invention provides a scraper-type saw blade. Compared with the prior art, it has the following advantages:

[0009] 1. This scraper-type saw blade is provided with an opening, a sandwich, a clamp, a scraper, and a linear hole. The scraper is welded and fixed in the clamp in the sandwich, so that part of the scraper is located in the saw blade body, making it less likely to break during use. The linear hole can eliminate stress, reduce thermal tensile cracks, and prevent the saw blade from deforming and cracking during use. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This utility model provides two technical solutions:

[0015] Example 1:

[0016] A scraper-type saw blade includes a saw blade body 1. The saw blade body 1 has an opening 2 inside. A sandwich 3 is provided on one side of the opening 2. A clamping opening 31 is provided inside the sandwich 3. A scraper 4 is fixedly connected inside the clamping opening 31. The saw blade body 1 has linear holes 5 inside. Four sets of linear holes 5 are arranged in a circular pattern.

[0017] Example 2:

[0018] A scraper-type saw blade includes a saw blade body 1. The saw blade body 1 has an opening 2 inside. Multiple sets of openings 2 are arranged oppositely. The openings 2 are C-shaped. The corners of the openings can be used for chip removal. A sandwich 3 is provided on one side of the opening 2. A clamping opening 31 is provided inside the sandwich 3. A scraper 4 is fixedly connected inside the clamping opening 31. Multiple sets of scrapers 4 are provided and are all located inside the openings of the openings 2, resulting in high cutting efficiency. The saw blade body 1 has linear holes 5 inside. Four sets of linear holes 5 are arranged in a circular pattern.

[0019] The scraper 4 is welded and fixed in the clamp 31 in the interlayer 3, so that part of the scraper 4 is located in the saw blade body 1, which makes it less likely to break during use. It is also provided with linear holes 5, which can eliminate stress, reduce thermal tensile cracks, and prevent the saw blade from deforming and cracking during use.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
