Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cover shell material blocking integrated structure of a handheld cooling saw. Background Art

[0002] For steel, the metal cutting method generally uses shearing machine and sawing machine. The requirement of cutting is to ensure that the cross section of the steel is not damaged. Except for a few simple sections of square, round and angle steel, which sometimes use forming shears that match the cross section, most steel is cut by sawing. Sawing can be divided into hot sawing and cold sawing. The sawing process of metal circular sawing machine is referred to as metal cold sawing. When metal is cold sawed, the heat generated by the saw blade teeth cutting the workpiece is transferred to the sawdust through the saw teeth, and the sawed workpiece and saw blade are kept cool, hence the name cold sawing. The saw blade has no surface treatment and is mainly used for sawing non-ferrous metal materials such as copper and aluminum. The main advantage is that the saw blade is thin. Sawing copper and other non-ferrous metals can greatly reduce material loss and save costs. Hot sawing has the advantages of rapid post-rolling processing, compact equipment, and low sawing force, and is widely used.

[0003] When sawing, the object to be cut needs to be placed at the cooling saw opening cutting position, and an additional block structure needs to be set at the cutting position to make the cutting material and the block structure offset each other to ensure the accuracy of the cutting operation. The current block structure mainly consists of additional metal parts set at the cutting position. The additional installation and fixation of metal parts will increase the equipment processing procedures, resulting in high production costs. It also has defects such as inconvenient disassembly and replacement. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the utility model is to provide a cover shell material stopper integrated structure of a handheld cooling saw to solve the problems of complex cutting position processing and high production cost of the existing handheld cooling saw.

[0006] In the present technical solution, the saw blade cover and the saw blade cover are assembled and installed at the front end of the cooling saw to accommodate the saw blade structure. By setting a cutting port as the cutting position of the cooling saw, the present technical solution adopts an extended stop block at the bottom of the cutting port, and the stop iron on the saw blade cover is directly bent to fit the stop block position, thereby ensuring the stability of the stop block structure. During cutting, the stop iron area can directly contact the material to ensure the accuracy of the cutting position, while having a higher wear-resistant effect. Compared with the prior art of adding an additional metal structure at the cutting port position, the present technical solution has a simpler and more reasonable structure, a more solid structure, and is easy to assemble and process, which can effectively reduce production costs.

[0007] Preferably, the surface of the stop block is provided with a stepped groove that cooperates with the stop iron.

[0008] Preferably, the edge of the saw blade cover is provided with a plurality of connection holes arranged at intervals, and the edge of the saw blade cover is provided with rivet nuts arranged one-to-one corresponding to the connection holes.

[0009] Preferably, the saw blade cover and the saw blade cover plate are provided with an assembly hole at the center thereof for the saw blade shaft to pass through, and the saw blade cover is provided with a plurality of mounting holes at the periphery thereof corresponding to the assembly hole.
