Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting saw blades, in particular to an assembled metal cutting saw blade component. Background Art

[0002] Saw blade is a general term for thin circular tools used to cut solid materials. Metal cutting saw blades include multiple parameters such as the type of alloy cutter head, base material, diameter, number of teeth, thickness, tooth shape, angle, aperture, etc. These parameters determine the processing capacity and cutting performance of the saw blade.

[0003] After searching, a kind of assembled saw blade assembly with the publication number CN209021347U is found, which includes: a circular tube, a fixed saw blade assembly sleeved on the outer circle of the circular tube and two adjustable saw blade assemblies located on the outer side of the circular tube, the adjustable saw blade assemblies are respectively located on both sides of the fixed saw blade assembly and are rotatably connected thereto; the fixed saw blade assembly includes a shaft sleeve tightly matched with the outer circle of the circular tube and a first saw blade sleeved on the outer circle of the shaft sleeve, and the outer circles at both ends of the shaft sleeve are respectively provided with external threads; the adjustable saw blade assembly includes a rotating sleeve and a second saw blade connected to the outer end of the rotating sleeve, and the inner wall of the rotating sleeve is provided with internal threads corresponding to the external threads. Through the above-mentioned method, the assembled saw blade assembly described in the utility model can use three saw blades for cutting at the same time, which improves the cutting efficiency. Loosen the locking nut and rotate the adjustable saw blade assembly to determine the cutting distance between the first saw blade and the second saw blade, which improves the convenience of adjustment.

[0004] In view of the above-mentioned related technologies, the inventor believes that although the above-mentioned device can adjust the cutting distance between the saw blades, the distance adjustment between the saw blades is completed through the nut and the corresponding threaded connection relationship. Since the saw blade will vibrate during the cutting process, as the use time increases, the nut will loosen and the sleeve and the rotating sleeve will loosen, which will affect the stability of the saw blade during use. In addition, the above-mentioned device cannot increase the number of saw blades according to specific use requirements, resulting in certain limitations during use. For this reason, we propose an assembled metal cutting saw blade assembly. Utility Model Content

[0005] In view of the problems existing in the above-mentioned existing assembled metal cutting saw blade assembly, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide an assembled metal cutting saw blade assembly, which solves the problem that although the above-mentioned device can adjust the cutting distance between the saw blades, the distance adjustment between the saw blades is completed by a nut and a corresponding threaded connection relationship. Since the saw blade will vibrate during the cutting process, as the use time increases, the nut will become loose and the sleeve and the rotating sleeve will become loose, which will affect the stability of the saw blade during use. In addition, the above-mentioned device cannot increase the number of saw blades according to specific use requirements, resulting in certain limitations during use.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Preferably, the adjustable cutting saw blade is provided with two limiting mechanisms, and the two limiting mechanisms are symmetrically distributed on the sleeve.

[0010] Preferably, a pull ring is provided on the engaging connection end of the insertion rod and the fixing seat, and a rubber sleeve is nested on the pull ring.

[0011] Preferably, a fixing plate is provided at a section of the insertion rod located inside the fixing seat, a spring is nested on the insertion rod, and the spring is press-fitted between the fixing plate and the top inner wall of the fixing seat.

[0012] Furthermore, a protective cover is provided on the fixing seat, and the inner wall height of the protective cover is consistent with the height of the pull ring.

[0013] Preferably, a guide groove is provided on the outer wall of the circular tube, a guide strip is welded on the inner wall of the sleeve, and the sleeve is engaged and connected with the guide groove via the guide strip.

[0026] The utility model discloses an assembled metal cutting saw blade assembly, wherein two limiting mechanisms 8 are provided on the adjustable cutting saw blade 3, and the two limiting mechanisms 8 are symmetrically distributed on the sleeve 6, which can improve the limiting and fixing effect of the adjustable cutting saw blade 3, thereby improving the stability of the adjustable cutting saw blade 3 during use.

[0027] The utility model is an assembled metal cutting saw blade assembly, a pull ring 15 is provided on the chimeric connection end of the insertion rod 12 and the fixing seat 10, and a rubber sleeve is embedded on the pull ring 15, which can conveniently drive the insertion rod 12 to move through the pull ring 15, thereby improving the convenience of use.

[0028] The utility model is an assembled metal cutting saw blade assembly, in which a section of an insertion rod 12 located inside a fixed seat 10 is provided with a fixed plate 13, a spring 14 is nested on the insertion rod 12, and the spring 14 is pressed between the fixed plate 13 and the top inner wall of the fixed seat 10. Through the elastic force of the spring 14, a certain external force can be applied to the fixed plate 13 and the insertion rod 12, so that the insertion rod 12 can always be inserted into the inside of the limiting hole 4.

[0029] The utility model discloses an assembled metal cutting saw blade assembly, a protective cover 16 is provided on the fixed seat 10, the inner wall height of the protective cover 16 is matched with the height of the pull ring 15, and the pull ring 15 can be limited, so as to avoid the adjustable cutting saw blade 3 being affected by the centrifugal force during the rotation process, causing the spring 14 to deform, thereby affecting the connection stability between the sleeve 6 and the round tube 1.

[0030] The utility model discloses an assembled metal cutting saw blade assembly, a guide groove 5 is opened on the outer wall of a circular tube 1, a guide strip 9 is welded on the inner wall of a sleeve 6, and the sleeve 6 is engaged with the guide groove 5 through the guide strip 9, which can provide a limiting guide function for the sleeve 6, avoiding the need to re-position the adjustable cutting saw blade 3 after adjustment, thereby improving the convenience of use, and at the same time providing a certain support force for the rotation of the adjustable cutting saw blade 3.
