Description

Technical Field

[0001] The utility model relates to the technical field of section steel cutting equipment, in particular to a small section steel cutting device. Background Art

[0002] In the production and processing of steel structures, steel materials such as angle steel, channel steel, and square tubes are often used. These steel materials often have standard models and sizes for selection. During the production and processing process, the steel only needs to be cut according to the required length before use. Currently, the cutting of steel is mainly completed by cutting machines. However, during the cutting process, a large amount of metal debris will be generated by the cutting machine, which poses a certain fire risk and has low cutting efficiency. Especially in the process of cutting some small steel sections, the heat generated by friction may also cause deformation of the steel section, stress concentration and other problems, affecting the quality of the steel section. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a small steel cutting device to solve the problems of low efficiency in current small steel cutting and possible deformation and stress concentration of steel due to heat, which may affect the quality of steel.

[0004] The technical solution adopted by the present invention is: a small-sized steel cutting device, comprising an equipment support and a cutting assembly, wherein the cutting assembly is detachably connected to the equipment support, the cutting assembly comprises a mold mechanism, a cutting knife and a first driving mechanism, the first driving mechanism is connected above the mold mechanism, the cutting knife is connected to the first driving mechanism, and the cutting knife is slidably connected to the inner side of the mold mechanism, and a support assembly for supporting the steel section is also installed on the equipment support, the support assembly comprises a first support and a plurality of first support wheels detachably connected to the first support.

[0005] The above structure has the following beneficial effects:

[0006] 1. The cutting assembly is detachably connected to the equipment bracket, so that different cutting assemblies can be switched according to different steel sections, so as to be suitable for cutting steel sections of different models and sizes.

[0007] 2. The cutting knife slides inside the mold mechanism, which can ensure that the cutting knife can stably cut the steel. At the same time, the first driving mechanism adopts a hydraulic cylinder, which drives the cutting knife to cut the steel. Not only is the cutting speed fast, but it also avoids excessive heat generation during the cutting process, thereby avoiding the problem of steel deformation or stress concentration due to heat.

[0008] 3. The support component supports the section steel through a detachable first support wheel, ensuring that the section steel can enter the cutting component stably. At the same time, the first support wheel can also be switched into different shapes according to the specification model of the section steel to ensure stable support for different section steels.

[0009] Preferably, a receiving plate is further installed on the equipment support. A length - fixing mechanism is installed on the receiving plate. The receiving plate is an angle steel, and the length - fixing mechanism includes a mobile end slidably connected to one side edge of the angle steel and a limiting end for limiting the section steel. The mobile end is in a "冂" shape, and the limiting end is fixedly connected to one side of the mobile end.

[0010] The receiving plate can receive the cut section steel, preventing the section steel from falling from the equipment support and being damaged. At the same time, it can adjust the position of the length - fixing mechanism slidably connected to the receiving plate according to the required size to position the cut section steel. This not only improves the cutting efficiency but also accurately positions the size, thus improving the product quality.

[0011] Preferably, the length - fixing mechanism and the receiving plate are locked by a first locking mechanism. The first locking mechanism includes a threaded hole opened on the side of the mobile end away from the limiting end, and a locking bolt is threadedly connected to the threaded hole.

[0012] By rotating the locking bolt, the locking bolt can be tightened against the side wall of the receiving plate to fix the relative position of the length - fixing mechanism and the receiving plate, thereby blocking the section steel during the feeding process of the section steel, so that the cutting length of the section steel does not exceed the length set by the length - fixing mechanism, further improving the stability of the length - fixing mechanism for length limitation.

[0013] Preferably, a number of teeth are provided on the side plate of the mobile end away from the threaded hole.

[0014] When the locking bolt is tightened against the receiving plate, the length - fixing mechanism is pulled to translate, so that the teeth are abutted against the receiving plate. Through the friction between the teeth and the receiving plate, the stability of the fixed state of the length - fixing mechanism can be further improved, making the length - fixing mechanism not move easily.

[0015] Preferably, a number of rollers are further provided on the mobile end, and the rotating shaft of the roller is connected to the mobile end through a first elastic member.

[0016] The setting of several rollers enables the fixed-length mechanism to be connected to the receiving plate through the rollers when adjusting the position, thereby reducing the friction between the fixed-length mechanism and the receiving plate. On the one hand, it reduces the wear of the material, and on the other hand, it can also make the position adjustment of the fixed-length mechanism smoother and faster; at the same time, the setting of the first elastic member enables the roller to be pushed into the side wall of the moving end when the locking bolt is tightened, so that the teeth are against the receiving plate, and when the locking bolt is loosened, the roller is against the receiving plate under the action of the first elastic member, facilitating its movement.

[0017] Preferably, the equipment bracket is further detachably connected to a first guide wheel, and the first guide wheel is located above the first support wheel.

[0018] The setting of the first guide wheel can guide the steel section during feeding, so that the steel section remains in the center position; at the same time, the first guide wheel is detachably connected, which also allows the first guide wheel to be replaced with guide wheels of different specifications according to the specifications of the cut steel section, thereby being able to stably support different steel sections.

[0019] Preferably, a lifting mechanism is provided between the first guide wheel and the equipment bracket, and the lifting mechanism includes a second bracket, a slider and a second driving member. A slide groove is provided inside the second bracket, the slider is slidably connected to the slide groove, and the first guide wheel is connected to the slider.

[0020] The lifting mechanism can drive the first guide wheel to rise and fall, so that the first guide wheel only descends when in use, maintains a state of contact with the steel section, and ensures that the steel section is centered. During the steel section loading process, it can be raised to facilitate the steel section to enter between the first guide wheel and the first support wheel, thereby improving the loading efficiency.

[0021] Preferably, a second elastic member is further provided between the rotating shaft of the first guide wheel and the slider.

[0022] The provision of the second elastic member allows the first guide wheel to have a certain amount of movement margin during the lifting process, thereby ensuring that the first guide wheel can stably contact the section steel.

[0023] Preferably, the equipment bracket is further connected with several groups of second guide wheels, two of the second guide wheels form a group, and the two second guide wheels in each group are respectively located on both sides of the steel section, and the second guide wheels are against the steel section.

[0024] The second guide wheel can guide the side of the steel section, further ensuring that the steel section can remain in a centered position, thereby improving stability during the cutting process.

[0025] Preferably, an adjustment assembly is provided between the two second guide wheels in each group, and the adjustment assembly includes an adjustment base and two adjustment arms. The second guide wheel is rotatably connected to the adjustment arm. A guide groove is provided on the adjustment base, and a guide block matching the guide groove is provided on the adjustment arm, and a stud is connected between the two adjustment arms.

[0026] By rotating the stud, the adjustment arms on both sides of the adjustment base can be moved in opposite directions, so that the two adjustment arms can be moved closer or farther away synchronously to adjust the position of the second guide wheel; at the same time, the setting of the guide groove and the guide block can guide the movement of the adjustment arm, ensuring that the adjustment process of the adjustment arm is stable and smooth.
