CONCRETE IMPLEMENTATION

[0028] Embodiment one:

[0029] Please refer to Figures 1-5The embodiment is an electric guide rail cutting machine 100, which comprises a machine body 1 and a cutter head module 2 arranged at the front end of the machine body 1. The cutter head module 2 comprises a fixed cutter assembly 21 for positioning the guide rail and a movable cutter blade 22 capable of rotating to cut the guide rail. The fixed cutter assembly 21 is provided with a profiled opening 23 for the guide rail to pass through and to position the guide rail. The profiled opening 23 is profiled with the longitudinal section of the guide rail.

[0030] The fixed cutter assembly 21 comprises a first fixed cutter blade 211 arranged on the machine body 1 and a second fixed cutter blade 212 detachably arranged on the first fixed cutter blade 211. The first fixed cutter blade 211 and the second fixed cutter blade 212 are arranged in parallel relative to each other and form a clearance for the movable cutter blade 22 to rotate. The first fixed cutter blade 211 is provided with a first profiled opening 214, and the second fixed cutter blade 212 is provided with a second profiled opening 215. The first profiled opening 214 and the second profiled opening 215 are both profiled with the longitudinal section of the guide rail, and the first profiled opening 214 and the second profiled opening 215 are aligned and coincide to form the profiled opening 23.

[0031] In the embodiment, the product to be cut is a guide rail, and therefore the profiled opening 23 is profiled with the longitudinal section of the guide rail. When the guide rail is to be cut, the entire guide rail is inserted into the profiled opening 23. On the one hand, the profiled opening 23 can realize profiled positioning of the guide rail, thereby improving the positioning accuracy of the guide rail. On the other hand, when the movable cutter blade 22 cuts the guide rail, even if the movable cutter blade 22 has a large pressure on the guide rail, the profiled positioning of the profiled opening 23 can prevent the guide rail from moving, thereby ensuring the stability of the positioning of the guide rail and ensuring the smoothness of the cut of the guide rail, and improving the cutting accuracy of the guide rail. Therefore, the profiled opening 23 can not only improve the positioning accuracy of the guide rail, but also improve the cutting accuracy of the guide rail.

[0032] In other embodiments, the profiled opening 23 can be used to cut other products, and the shape of the profiled opening 23 can be adjusted according to different products. The specific structure of the profiled opening 23 is not limited herein. For example, if a pipe is to be cut, the profiled opening 23 is a circular opening profiled with the pipe. If a square profiled material is to be cut, the profiled opening 23 is a square opening profiled with the profiled material.

[0033] The first fixed blade 211 is provided with a mounting block 216 on the side facing the second fixed blade 212, and the second fixed blade 212 is mounted on the mounting block 216 by means of fasteners 217, so as to achieve the fixed mounting of the second fixed blade 212 on the first fixed blade 211. The first fixed blade 211, the mounting block 216 and the second fixed blade 212 are all provided with mounting holes 218 matched with the fasteners 217. The mounting block 216 is spaced between the first fixed blade 211 and the second fixed blade 212, so that an avoiding gap is formed between the first fixed blade 211 and the second fixed blade 212 for the rotating movement of the moving blade 22. The thickness of the mounting block 216 is the size of the avoiding gap, and the size of the avoiding gap is set according to the thickness of the moving blade 22. The size of the avoiding gap is set to enable the moving blade 22 to rotate smoothly and quickly, and the size of the avoiding gap is not limited herein and can be set according to actual conditions.

[0034] Since the moving blade 22 will rotate into the avoiding gap to avoid the interference between the mounting block 216 and the moving blade 22, the mounting block 216 is arranged on the outer edge of the first fixed blade 211 and is located on the side away from the moving blade 22. The moving blade 22 is made of quenched material of pre-hardened plastic mold steel (P20), which has higher hardness and better durability, so as to improve the service life of the moving blade 22 and the service life of the electric guide rail cutting machine 100.

[0035] In the embodiment, two mounting blocks 216 are arranged to ensure the stability of the installation of the second fixed blade 212. In other embodiments, the mounting block 216 can be arranged in multiple numbers, or multiple mounting blocks can be arranged in an integrated structure to form one mounting block 216. The number of the mounting blocks 216 and the specific structure thereof are not limited herein and can be set according to actual conditions.

[0036] The fasteners 217 are arranged in multiple numbers to ensure the stability of the installation of the second fixed blade 212. The fasteners 217 can be selected from one of a screw, a bolt or a countersunk head pin, or can be other fasteners according to actual conditions. In order to ensure the aesthetics of the installation of the first fixed blade 211 and the second fixed blade 212, the fasteners 217 are arranged in a recessed manner, i.e. the two ends of the fasteners 217 are arranged inside the surfaces of the first fixed blade 211 and the second fixed blade 212, respectively.

[0037] The inside of the machine body 1 is provided with a driving module 3 for driving the moving blade 22 to rotate, and the tail of the machine body 1 is provided with a battery mounting groove 11, and a battery pack 4 is detachably mounted in the battery mounting groove 11 in a sliding and inserting manner. The structure of the machine body 1 adopts a portable handheld structure, and the handheld machine body is a conventional design which will not be described herein. In the embodiment, the machine body 1 adopts a handheld structure, which is convenient to carry, small in size and light in weight, and can be directly held to cut the guide rail, without the need to carry the guide rail back and forth, saving time and effort. In other embodiments, the structure of the machine body 1 can be adjusted according to actual conditions, which is not limited herein.

[0038] The structure of the machine body 1, the structure of the driving module 3, the connection structure of the first fixed blade 211 and the machine body 1, the connection structure of the first fixed blade 211 and the moving blade 22, and the connection structure of the moving blade 22 and the driving module 3 are all prior art, and conventional designs can be adopted, and details are not described herein again, and can also refer to the designs in the documents of the electric pipe cutting machine cutter head and the electric pipe cutting machine published in CN214163084U.

[0039] When the electric guide rail cutting machine 100 provided by the scheme is applied, before cutting, the electric guide rail cutting machine 100 can be moved to one end of the guide rail, so that one end of the guide rail extends into the profiling opening 23, the electric guide rail cutting machine 100 is held by hand and moved along the guide rail to a position to be cut, the switch is actuated, the driving module 3 drives the moving blade 22 to rotate to one side of the fixed blade assembly 21, the moving blade 22 gradually cuts the guide rail, the cut guide rail is removed, the electric guide rail cutting machine 100 is continuously held by hand and moved along the guide rail to the next position to be cut, and the next section of the guide rail is continuously cut.

[0040] Embodiment two:

[0041] The structure of the electric guide rail cutting machine 100 in the embodiment is substantially the same as that in the first embodiment, and the difference lies in the structure of the fixed blade assembly 21. In the first embodiment, the fixed blade assembly 21 includes the first fixed blade 211 arranged on the machine body 1 and the second fixed blade 212 arranged on the first fixed blade 211 in a detachable manner, the first fixed blade 211 and the second fixed blade 212 are arranged opposite to each other and form an avoiding gap for the rotating movement of the moving blade 22. In the embodiment, the fixed blade assembly 21 includes a fixed blade, and the cutter body of the fixed blade is also provided with a profiling opening 23 for the guide rail to pass through and for positioning the guide rail. The profiling opening 23 is arranged in profile with the longitudinal section of the guide rail, and the driving module 3 drives the moving blade to rotate to one side of the fixed blade to cut the guide rail.
