Description

Technical Field

[0001] The utility model relates to the technical field of saw blade production and processing, in particular to a saw blade burr remover. Background Technique

[0002] A saw blade is a cutting tool, usually installed on a hand saw or a table saw, and cuts an object through the structure of the saw teeth. The material of the saw blade is mostly steel, which has certain flexibility and hardness and can adapt to different cutting requirements. According to different uses, saw blades can be divided into metal cutting saw blades, woodworking saw blades, stone saw blades, etc. Their saw tooth shapes and densities are also different to meet the cutting requirements of different materials.

[0003] At present, there are various uneven burrs on the surface of the saw blade during the production process. Especially during the process of blanking and tooth making of the saw blade, there are many burrs on the edge of the tooth pattern of the saw blade, which need to be removed. Currently, the main method is to remove the burrs by manual or machine grinding. Manual grinding has low grinding efficiency, slow grinding speed, high labor intensity of workers, and is prone to over-grinding and damaging the tooth profile of the saw blade during the burr removal process. Machine grinding can only grind one side at a time, and the saw blade needs to be turned over during the grinding process, resulting in low grinding efficiency. Therefore, a saw blade burr remover is needed. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a saw blade burr remover to solve the problem that currently, there are various uneven burrs on the surface of the saw blade during the production process. Especially during the process of blanking and tooth making of the saw blade, there are many burrs on the edge of the tooth pattern of the saw blade, which need to be removed. Currently, the main method is to remove the burrs by manual or machine grinding. Manual grinding has low grinding efficiency, slow grinding speed, high labor intensity of workers, and is prone to over-grinding and damaging the tooth profile of the saw blade during the burr removal process. Machine grinding can only grind one side at a time, and the saw blade needs to be turned over during the grinding process, resulting in low grinding efficiency.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A saw blade burr remover includes a workbench. Four support legs are arranged at the bottom end of the workbench. A saw blade slide rail is arranged on the top surface of the workbench. A chute is arranged at the top of the saw blade slide rail. A burr removal box is fixedly installed on the top of the workbench. Two burr grinding pieces are installed inside the burr removal box. The two burr grinding pieces are respectively arranged on the front and back sides of the saw blade slide rail. A saw blade with burrs to be removed is installed in the chute at the top of the saw blade slide rail.

[0007] As a preferred technical solution of the present utility model, the two burr grinding sheets arranged on the front and rear sides of the saw blade slide rail are arranged non-coaxially and staggeredly inside the burr removal box.

[0008] As a preferred technical solution of the present utility model, two working cavities are provided inside the burr removal box, and the two working cavities are arranged staggeredly inside the burr removal box. A servo motor is arranged inside each working cavity, and an output shaft extends from the servo motor towards the saw blade slide rail. The burr grinding sheets are respectively arranged at the top ends of the output shafts of the servo motors in the two working cavities.

[0009] As a preferred technical solution of the present utility model, a threaded lead screw is rotatably connected to the inner wall of each working cavity, and servo motors I are symmetrically installed on the front and rear sides of the burr removal box. The output shafts of the two servo motors I are respectively fixedly connected to the top ends of the threaded lead screws.

[0010] As a preferred technical solution of the present utility model, a walking frame is slidably connected inside each working cavity. The servo motor is fixed to the top end of each walking frame. A slider is fixed to the top end of the walking frame, and a through threaded hole is provided in the middle of the slider. The threaded hole in the middle of the slider is threadedly connected to the threaded lead screw in the corresponding working cavity.

[0011] As a preferred technical solution of the present utility model, a slide rail groove is provided at the bottom end of each working cavity, and the bottom end of the walking frame is slidably connected inside the slide rail groove.

[0012] As a preferred technical solution of the present utility model, a supporting plate is fixed in the middle of the four support legs.

[0013] In the present utility model, the saw blade to be deburred is placed in the chute at the top end of the saw blade slide rail. By pushing the saw blade to slide in the chute of the saw blade slide rail, when the saw blade passes through the burr removal box, the burr grinding sheets located on the front and rear sides of the saw blade slide rail inside the burr removal box are used to polish the saw blade to be deburred, so that both sides of the saw blade can be polished when the saw blade slides once in the chute of the saw blade slide rail, thus eliminating the need to turn the saw blade over to polish the burrs and improving the burr removal efficiency.

[0014] In the present utility model, the two non-coaxially and staggeredly arranged burr grinding sheets inside the burr removal box can simultaneously polish the burrs on both sides of the saw blade with a relatively thin thickness, and have high polishing efficiency and fast polishing speed. The two burr grinding sheets inside the burr removal box are driven by a threaded transmission between the walking frame and the threaded lead screw to realize the reciprocating movement of the burr grinding sheets inside the working cavity. The threaded transmission can make the burr grinding sheets be fixed at any position during movement, and has high movement accuracy, which can effectively ensure the polishing uniformity of the burr grinding sheets and effectively avoid excessive polishing during the polishing process.

[0015] In the present utility model, the saw blade is manually placed into the chute at the top of the saw blade slide rail. By manually pushing and pulling the saw blade to move it once in the chute, both sides of the saw blade can be polished. The polishing efficiency is high and the polishing speed is fast. Compared with manual polishing, the labor intensity of workers can be significantly reduced.
